Representational Tradeoffs in Value-Based Imitation Learning","source":"arxiv","abstract":"Imitation learning (IL)---training an agent to replicate expert behavior from demonstrations---underpins applications from robotics to language model training. Standard approaches such as Behavior Cloning (BC) are known to suffer from compounding errors and performance plateaus, particularly when the learner cannot perfectly represent the expert's policy (as is typical, e.g., in distillation). Two interventions are widely understood empirically to improve performance: querying the expert interactively along the learner's own trajectories, and using value function estimation en route to generating a policy rather than directly fitting the expert's full action distribution. We investigate the nature of these improvements and their potentially surprising interplay. Our main finding is that expert interaction relaxes the representational demands on the learner: one only needs a model capable of realizing the expert's value function, bypassing the (often stricter) requirement of realizing the expert's policy itself. Concretely, we introduce OVI, an interactive on-policy IL algorithm that is statistically efficient whenever the learner can represent the expert's value function and computationally efficient given access to a linear maximization oracle. We complement this with a negative result showing that interaction is necessary. Namely, without stronger assumptions beyond expert-value realizability alone, any offline IL algorithm must scale with the complexity of the expert policy class. Our findings bear out empirically. OVI outperforms offline policy-based (BC), interactive policy-based (DAgger), and offline value-based IL methods, with the largest gains when the learner network is substantially less expressive than the expert's.","url":"https://arxiv.org/pdf/2607.29617v1","authors":["Luca Viano","Antoine Moulin","Audrey Huang","Volkan Cevher","Philip Amortila","Dylan J.

Among RL methods, critic-based approaches rely on a value estimator that predominantly operates on single-frame observations or single-frame VLM backbone latents, which is a fundamental mismatch with the partially observable nature of robot control. A naive approach to incorporate observation history into the critic incurs exponential complexity with high-dimensional visual space, and still fails because pure scalar-return regression provides insufficient supervision for learning cross-temporal dynamics. We identify the root cause as a state approximation problem: without an explicit world modeling objective, the critic's representation cannot capture the temporal structure needed for accurate value estimation. To address this, we propose the World Critic Model (WCM), built on a lightweight LeJEPA architecture; WCM jointly predicts future latent state and estimates values, such that the critic's representation is explicitly trained to capture temporal dynamics rather than merely regress scalar returns. WCM integrates seamlessly into both on-policy and off-policy training pipelines and is compatible with state-of-the-art VLA backbones including Pi0, Pi0.5, and OpenVLA-OFT. Extensive experiments on 149 tasks across four benchmarks demonstrate that WCM consistently achieves state-of-the-art performance in both in-distribution and out-of-distribution settings, with particularly strong generalization gains. We further validate WCM on seven real-world manipulation tasks using OpenVLA-OFT and Pi0.5 with off-policy RL, confirming stable deployment across diverse settings.","url":"https://arxiv.org/pdf/2607.29613v1","authors":["Senyu Fei","Xiaopeng Yu","Siyin Wang","Xianzhong Zhao","Jingjing Gong","Xipeng Qiu"],"tags":[],"confidence":0.9,"sites":["exo-science","genetech-tools","robot-parts"],"publishedDate":"2026-07-31T16:48:45Z","addedAt":"2026-08-03T15:11:30.479Z"},{"id":"arxiv-2607.29622v1","name":"RayViT: Ray-Conditioned Visual Representations for Viewpoint-Robust Imitation Learning","source":"arxiv","abstract":"Visual imitation learning enables robots to acquire visuomotor skills directly from images, yet RGB observations lack explicit geometric cues, making learned policies brittle to camera perturbations.

This review examines the mechanisms and modalities of actuation deformation in materials that respond to various stimuli. Then, strategies based on composite materials are considered to build toward actuators that combine multiple actuation modes for sophisticated movements.

The review further highlights how the application of soft functional materials into robots with rigid components further enhances their locomotive abilities. Finally, taking advantage of the shape-morphing properties of soft materials, reconfigurable soft robots have shown the capacity for adaptive gaits that enable transition across environments with different locomotive modes for optimal efficiency.

This paper presents a systematic approach to implement the feedback control of FFA-based soft robotic bending modules by using commercial flex bend sensors. A flex bend sensor detects the module curvature in one direction, and its response is processed by an on board microcontroller and sent to the central control system. Such sensor integration enables the closed-loop control of modular robotic architectures, often used in soft robotics. Once integrated with the soft module, the sensor response was calibrated by the use of a ground truth electro-magnetic tracking system in order to characterize its behavior when combined with the relative FFA.

A proposed solution for active body weight support systems involves a linear actuator design, combining a high-force unit with an agile, highly back-drivable unit, using an electrorheological-fluid brake. This dissertation introduces an approach that utilizes an electromagnetic (EM) brake with a reduced rotor inertia to address these challenges. The EM brake's increased torque capacity allows for integration with a low-gear-ratio linear transmission. The mini motor, with low inertia, drives the agile movement of the endpoint through a pulley-belt mechanism, enabling high transparency. The rotor of the EM brake is connected to the pulley, and damping is modulated under high driving forces by adjusting the brake torque in relation to the rotational speed of the pulley. When the brake is engaged, it locks the motion between the endpoint and the moving carrier, ensuring that the endpoint is fully controlled by the high-force unit's ball screw, known as the \"macro.\" A scaled prototype was developed to experimentally analyze the damping force generated by both the mini motor and the EM brake.

Simplifying systems, reducing device size, and integrating multiple functions remain limiting factors for the miniaturization of optical imaging systems. Liquid lenses offer compact structure, fast response, and no mechanical parts, demonstrating potential for miniaturized imaging and rapid focusing. However, existing designs focus primarily on single-focus function, failing to simultaneously achieve fast continuous focusing, zoom capability, and reliable sealing in practical applications. This has resulted in limitations to the full realisation of its unique advantages, significantly restricting its application prospects in scenarios such as micro-visualisation and mobile imaging terminals. To address the issue, this study presents a compact dual-actuation multifunctional liquid lens. For the first time, a non-membrane, sealed dual-cavity design is employed to integrate both focusing and zoom functions into a single device. The lens employs two actuation modes-electrowetting-on-dielectric and electromagnetic induction-to adjust the curvature and axial position of the liquid-liquid interface, enabling an integrated compact lens that can be controlled entirely by electrical signals. Experimental results demonstrate that the proposed lens achieves continuous focusing with 100&#x2009;ms response time and provides smooth zoom from 1&#xd7; to 1.5&#xd7;, together with high resolution and stable imaging quality. With its simple architecture and integrated functions, the proposed liquid lens overcomes the functional and packaging limitations of traditional non-membrane liquid lenses.

The development of universal grippers able to pick up unfamiliar objects of widely varying shape and surface properties remains, however, challenging. Most current designs are based on the multifingered hand, but this approach introduces hardware and software complexities. These include large numbers of controllable joints, the need for force sensing if objects are to be handled securely without crushing them, and the computational overhead to decide how much stress each finger should apply and where. Here we demonstrate a completely different approach to a universal gripper. Individual fingers are replaced by a single mass of granular material that, when pressed onto a target object, flows around it and conforms to its shape. Upon application of a vacuum the granular material contracts and hardens quickly to pinch and hold the object without requiring sensory feedback. We find that volume changes of less than 0.5% suffice to grip objects reliably and hold them with forces exceeding many times their weight. We show that the operating principle is the ability of granular materials to transition between an unjammed, deformable state and a jammed state with solid-like rigidity. We delineate three separate mechanisms, friction, suction, and interlocking, that contribute to the gripping force. Using a simple model we relate each of them to the mechanical strength of the jammed state. This advance opens up new possibilities for the design of simple, yet highly adaptive systems that excel at fast gripping of complex objects.","url":"https://doi.org/10.1073/pnas.1003250107","authors":["Eric Brown","Nicholas Rodenberg","John R.

Unlike previous research using vacuum for particle jamming, this paper proposes a novel passive particle jamming principle that does not need any vacuum power or other control means. The proposed method is by simply patching a silicone rubber soft actuator and a pack (made of strain-limiting membrane) of particles to form an integral gripping finger. The inflation of the soft actuator applies a pressure to the particle pack causing particles inside it to jam. A larger squeezing pressure will result in tighter particle jamming, thus increasing the stiffness of the finger. The stiffness of the finger is controllable as it is proportional to the actuator's air pressure, which has been verified by experiments in this research. The stiffness can increase more than six fold when air pressure changes from 20 to 80 kPa in the experimental studies.

For more effective grasping, a grasping strategy is designed for the proposed soft gripper with simultaneous consideration of grasping adaption and robustness.","url":"https://doi.org/10.1089/soro.2016.0027","authors":["Ying Wei","Yonghua Chen","Tao Ren","Chen Qiao","Changxin Yan","Yang Yang","Yingtian Li","Qiao Chen"],"tags":["Grippers","Actuator","Soft robotics","Robustness (evolution)","Stiffness"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2016-07-22","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1089/soro.2016.0027","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"oa:W2625731136","name":"A Soft-Robotic Gripper With Enhanced Object Adaptation and Grasping Reliability","source":"openalex","abstract":"A novel soft-robotic gripper design is presented, with three soft bending fingers and one passively adaptive palm.

Introduite comme une nouvelle technologie ces dernières années, la robotique souple ouvre de nouveaux horizons dans le domaine de la robotique grâce à des caractéristiques prometteuses telles que l'adaptabilité, la légèreté, la facilité d'assemblage et le faible coût pour réaliser des configurations complexes dans divers environnements. Même s'il existe une grande diversité d'applications pour les SFA, de nombreux défis subsistent dans ce domaine, notamment le contrôle de la rigidité et de la flexion. Pour illustrer les applications méthodologiques et théoriques actuelles des systèmes robotiques souples, le premier article présente une revue systématique des actionneurs fluidiques souples qui ont relèvent les défis critiques en matière de matériaux souples et actifs, de méthodes de traitement, d'architectures de préhension, de capteurs et de méthodes de contrôle. Différents modèles constitutifs de matériaux en silicone proposés et testés dans la littérature sont régénérés par le logiciel ABAQUS afin de comparer les données de déformation et de contrainte réelles issues des modèles constitutifs avec les données d'essai de traction standard basées sur la norme ASTM412. Cet article montre que la plupart de ces modèles peuvent prédire le modèle du matériau de manière acceptable dans une petite gamme de données de contrainte-déformation. Mais pour de grandes valeurs de contrainte-déformation, quelques-uns d'entre eux prédisent le comportement du matériau silicone avec précision. Le deuxième article présente un nouveau type de doigt souple avec une articulation mobile à commande pneumatique basée sur le contrôle du point de flexion et une rigidité variable. Le doigt proposé est plus performant que les solutions précédentes en termes d'espace 3D atteignable et de forces de contact applicables au bout du doigt en changeant la position de son articulation, et donc, le point de flexion. La méthode des éléments finis et l'algorithme NSGA-II sont appliqués pour optimiser la géométrie de l'articulation afin de maximiser l'angle de flexion et de minimiser les dimensions de l'articulation. Le troisième article de cette thèse se concentre sur le développement d'un nouveau type de préhenseur souple dextre avec trois doigts reconfigurables et une paume active améliorant les capacités de manipulation dextre. Dans chaque doigt, le point de flexion et la longueur de manipulation effective peuvent être modifiés et contrôlés en déplaçant une tige rigide insérée dans le trou central du doigt. La capacité de manipulation dextre de préhenseur robotique souple est validée par différents tests expérimentaux, notamment la rotation, les saisies multiples et le roulement. Par conséquent, deux types de paume artificiel à vide (ventouse et particules granulaires) sont utilisés pour garantir une large gamme de tâches de manipulation d'objets que les préhenseurs souples proposés précédemment ne peuvent pas complètement réaliser. Dans le dernier chapitre de cette thèse, le quatrième article propose un capteur tactile peu coûteux et facile à fabriquer pour des applications en robotique. Il est très flexible et facile à utiliser, ce qui en fait un choix approprié pour les applications de robots souples. La plupart des matériaux (encre conductrice, silicone, carte de contrôle) utilisés dans la fabrication de ce capteur sont peu coûteux et peuvent être trouvés facilement sur le marché. Le capteur capacitif proposé peut détecter la position et la force appliquée en mesurant la charge électrique des électrodes. En raison des incertitudes et des bruits, un réseau neuronal artificiel est proposé pour calibrer la force correspondant à l","url":"https://doi.org/10.70675/bd1218d2z58d4z457aza777zaea138b1a28c","authors":["Amir Pagoli"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-07T03:52:40Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.70675/bd1218d2z58d4z457aza777zaea138b1a28c","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1007/978-3-319-04663-1_29","name":"Sensitive Robotic Processes","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-319-04663-1_29","authors":["Christian Binder"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-03-20T09:50:56Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1007/978-3-319-04663-1_29","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1021/acsapm.6c00858.s003","name":"Natural Rubber-Based Soft Robotic Gripper with Tunable Performance","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsapm.6c00858.s003","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-29T16:00:46Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1021/acsapm.6c00858.s003","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1109/access.2025.3538001/mm1","name":"Motor-less Robotic Gripper: Driving Mechanism by Robotic Manipulator Movement_supp1-3538001.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/access.2025.3538001/mm1","authors":["Toshihiro NISHIMURA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-04T13:43:00Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1109/access.2025.3538001/mm1","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"oa:W2965255349","name":"Finite-Time Continuous Terminal Sliding Mode Control of Servo Motor Systems","source":"openalex","abstract":"In this article, a continuous terminal sliding mode control algorithm is proposed for servo motor systems.

First, a newly designed total sliding-mode control system, which is insensitive to uncertainties, including parameter variations and external disturbance in the whole control process, is introduced. The total sliding-mode control comprises the baseline model design and the curbing controller design. In the baseline model design, a computed torque controller is designed to cancel the nonlinearity of the nominal plant. In the curbing controller design, an additional controller is designed using a new sliding surface to ensure the sliding motion through the entire state trajectory. Therefore, in the total sliding-mode control system, the controlled system has a total sliding motion without a reaching phase. Then, to overcome the two main problems with sliding-mode control, i.e., the assumption of known uncertainty bounds and the chattering phenomena in the control effort, an RFNN sliding-mode control system is investigated to control the PM synchronous servo motor. In the RFNN sliding-mode control system, an RFNN bound observer is utilized to adjust the uncertainty bounds in real time. To guarantee the convergence of tracking error, analytical methods based on a discrete-type Lyapunov function are proposed to determine the varied learning rates of the RFNN. Simulated and experimental results due to periodic step and sinusoidal commands show that the dynamic behaviors of the proposed control systems are robust with regard to uncertainties.","url":"https://doi.org/10.1109/41.954557","authors":["Rong‐Jong Wai"],"tags":["Control theory (sociology)","Sliding mode control","Controller (irrigation)","Servomotor","Artificial neural network"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2001-01-01","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1109/41.954557","updatedAt":"2026-08-31T06:34:10.194Z"},{"id":"doi:10.1093/oed/9478990998","name":"servo motor, n.","source":"crossref","abstract":"","url":"https://doi.org/10.1093/oed/9478990998","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-07-19T09:26:39Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1093/oed/9478990998","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.21070/ups.2142","name":"Design An Automatic Shuttlecock Output Device Using An Arduino Based Servo Motor","source":"crossref","abstract":"","url":"https://doi.org/10.21070/ups.2142","authors":["Fadly Hikmatus S","Syamsudduha Syahrorini"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-28T01:49:00Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.21070/ups.2142","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1299/jsmelem.2015.8._0201-1_","name":"0201 Influence of Servo Activation Frequency on Servo Motor Temperature of Machine Tools Equipped with Idling Reduction System","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmelem.2015.8._0201-1_","authors":["Masahiro NIKI","Toshiki HIROGAKI","Eiichi AOYAMA","Keiji OGAWA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-06-24T22:26:50Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1299/jsmelem.2015.8._0201-1_","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1142/9789813206823_0099","name":"Modeling and Simulation of the Compound Servo System with Servo Motor and Hydraulic Motor","source":"crossref","abstract":"","url":"https://doi.org/10.1142/9789813206823_0099","authors":["Ze-Ming LONG","Bao-Jin GUAN","Guang-Jun CHEN","Hao-Yu LI","Shi-Qing GUO"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-07-17T01:59:44Z","addedAt":"2026-08-05T01:49:03.766Z","doi":"10.1142/9789813206823_0099","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.4236/9781649972883","name":"Adaptive Control of Dual-Motor Driving Servo System","source":"crossref","abstract":"This book is a summary of the author’s research achievements, which includes more than 20 academic papers published in domestic and foreign journals and academic conferences.

What kind of tactile information robots need, and how to use the information, remain open questions. We believe a soft sensor surface and high-resolution sensing of geometry should be important components of a competent tactile sensor. In this paper, we discuss the development of a vision-based optical tactile sensor, GelSight. Unlike the traditional tactile sensors which measure contact force, GelSight basically measures geometry, with very high spatial resolution. The sensor has a contact surface of soft elastomer, and it directly measures its deformation, both vertical and lateral, which corresponds to the exact object shape and the tension on the contact surface. The contact force, and slip can be inferred from the sensor's deformation as well. Particularly, we focus on the hardware and software that support GelSight's application on robot hands. This paper reviews the development of GelSight, with the emphasis in the sensing principle and sensor design. We introduce the design of the sensor's optical system, the algorithm for shape, force and slip measurement, and the hardware designs and fabrication of different sensor versions. We also show the experimental evaluation on the GelSight's performance on geometry and force measurement. With the high-resolution measurement of shape and contact force, the sensor has successfully assisted multiple robotic tasks, including material perception or recognition and in-hand localization for robot manipulation.","url":"https://doi.org/10.3390/s17122762","authors":["Wenzhen Yuan","Siyuan Dong","Edward H.

The fabricated TENG delivers an open-circuit voltage up to -1000 V, a short-circuit current density of 8 mA/m(2), and a power density of 500 mW/m(2) on a load of 100 MΩ, which can be used to directly drive tens of green light-emitting diodes.

An analysis of the evolution of this field shows how, after a few pioneering works in the years 2009 to 2012, breakthrough results were obtained by taking seminal technological and scientific challenges related to soft robotics from actuation and sensing to modeling and control. Further progress in soft robotics research has produced achievements that are important in terms of robot abilities-that is, from the viewpoint of what robots can do today thanks to the soft robotics approach. Abilities such as squeezing, stretching, climbing, growing, and morphing would not be possible with an approach based only on rigid links.

Flapping wings, sensitized robotic skins, insect-inspired compound eyes, and artificial muscles are examples of nature acting as a source of inspiration for the design of novel artificial systems. The heart of successful bioinspired design is the abstraction of the underlying design principles found in biology and their implementation in robotics using state-of-the-art technology. In this article, I introduce the notion of the inspire–abstract–implement (IAI) design flow as a paradigm for biological inspiration in robotics. The article develops the key aspects of the IAI approach and illustrates it on several examples in technology and on a case study of a miniature soft jumping robot.

The effects of thermal conductivity of the composite, offset displacement, and actuation frequency on the actuator speed are investigated using both experiments and finite element analysis. The actuator yields a bending speed as high as 28.7 cm −1 /s, 10 times that without the snap-through instability.

The mathematical model assumes the presence of a number of holonomic and nonholonomic constraints, as well as the presence of two servo-constraints containing a control function. The control function is defined in accordance with the features of the simulated scenario. Servo-constraints set the motion program. To implement the motion program, the pendulum actuator generates a control torque which is obtained from the joint solution of the equations of motion and derivatives of servo-constraints. The first and second components of the control torque vector are determined in a unique way, and the third component is determined from the condition of minimizing the square of the control torque. The system of equations of motion after reduction for a given control function is reduced to a nonautonomous system of six equations. A rigorous proof of the boundedness of the distance function between a spherical robot and a target moving at a bounded velocity is given. The cases where objects move in a straight line and along a curved trajectory are considered. Based on numerical integration, solutions are obtained, graphs of the desired mechanical parameters are plotted, and the trajectory of the target and the trajectory of the spherical robot are constructed.","url":"https://doi.org/10.20537/nd221223","authors":["E.

Actuators with flexible shapes allow them to operate in a wider variety of environments, and actuators with multiple degrees of freedom allow them to generate more complex motions. Here we propose a soft pneumatic actuator in the form of a thin, flexible sheet that can generate different motion vector fields on a surface. The proposed actuator is made by a novel multilayer additive process, which allows dozens of thin pneumatic chambers and multi-channel pneumatic circuits connecting them to be precisely formed in a thin soft body. A soft body containing such a complex pneumatic network can have a high degree of freedom and act like a transducer, with its surface dynamically responding to the input pressures. Depending on the input sequence, the proposed actuator can generate surface movements in six different directions, at different speeds, and over different distances, which we demonstrate through analytical models and experiments. We show that our proposed actuator can be used in a variety of environments where conventional rigid and thick actuators are difficult to use, including inspection and obstacle removal in narrow pipes, in-hand manipulation between conventional robotic grippers, and object transportation.","url":"https://doi.org/10.21203/rs.3.rs-4690825/v1","authors":["Hyung Gon Shin","Wan Kyun Chung","Keehoon Kim"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.21203/rs.3.rs-4690825/v1","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.15607/rss.2005.i.020","name":"Single Actuator Control Analysis of a Planar 3DOF Hopping Robot","source":"crossref","abstract":"","url":"https://doi.org/10.15607/rss.2005.i.020","authors":["Nicholas Cherouvim","Evangelos Papadopoulos"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-01-02T21:36:08Z","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.15607/rss.2005.i.020","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1109/robot.1990.126281","name":"Hybrid actuator for robot manipulators: design, control and performance","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1990.126281","authors":["J.K.

Given that the use of chopsticks requires sophisticated muscle control, they are difficult to use for unskilled people. In this study, a chopstick robot that uses a new soft actuator was developed. Firstly, we developed an X-shaped soft actuator and tested its performance. When a voltage was applied to the actuator, the gap in the X shape was reduced by the resulting electrostatic force. Conversely, when the power was turned off, the actuator recovered its original shape owing to the elasticity of its material. We attached the X-shaped soft actuator between the chopsticks. The chopstick robot, controlled by the input voltage, can pick up various objects in the switched-on state and is able to release them when switched off. We tested the performance of the chopstick robot and analyzed the forces acting on the chopsticks. The robot can be used for picking up various objects. Moreover, the X-shaped actuator can be adapted for use in various studies, through different shapes and configurations.","url":"https://doi.org/10.3390/act9020032","authors":["Kahye Song","Youngsu Cha"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-04-28T05:05:32Z","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.3390/act9020032","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.2316/p.2011.723-044","name":"Exoskeleton Robot using Hydraulic Bilateral Servo Actuator System for Non-Ambulatory Person's Transfer","source":"crossref","abstract":"","url":"https://doi.org/10.2316/p.2011.723-044","authors":["Julien Monnet","Yukio Saito","Kengo Onishi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-04-20T13:36:15Z","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.2316/p.2011.723-044","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1142/9789814725248_0054","name":"GAIT PLANNING AND STABILIZATION FOR BIPED ROBOT WITH ONE ACTUATOR","source":"crossref","abstract":"","url":"https://doi.org/10.1142/9789814725248_0054","authors":["WENYUAN LIANG","LI MICHAEL LIU","JIANFEI LI"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-08-26T02:45:17Z","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.1142/9789814725248_0054","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/cac48633.2019.8996632","name":"IDA-PBC of the robot manipulator including actuator dynamics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/cac48633.2019.8996632","authors":["Yue Wang","Haisheng Yu","Herong Wu","Xudong Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-02-14T08:25:50Z","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.1109/cac48633.2019.8996632","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/tac.2015.2460393","name":"Controllability and Observability of an -Link Planar Robot with a Single Actuator Having Different Actuator–Sensor Configurations","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tac.2015.2460393","authors":["Yannian Liu","Xin Xin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-07-23T18:33:06Z","addedAt":"2026-08-06T15:48:05.813Z","doi":"10.1109/tac.2015.2460393","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1109/aim.2016.7576750","name":"Improved hybrid pneumatic-electric actuator for robot arms","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim.2016.7576750","authors":["Graham Ashby","Gary M.

The actuator pressure dynamics were considered, and an exact model knowledge integrator backstepping-based, IB, controller was designed with flow rates as the system’s control inputs. A more realistic valve flow model was then developed with valve control currents as the system inputs. Exact model knowledge based plant inversion techniques were used to compute the required control current given the desired flow rate and chamber pressure. In order to avoid reverse flow in the valves and singularities in the flow function, the controller gains were adjusted to ensure that the chamber pressures were maintained above and below the exhaust and supply pressures, respectively, throughout the experiments. Furthermore, flow choking, i.e. valve saturation, imposed further limitation on the system’s bandwidth. The tracking performance of the IB controller, when compared to linear PD control, was found to provide superior tracking performance. Finally, it is hypothesized that the tracking speed for IB control can be increased, by varying the value of the computed (i.e. desired) control based on the desired direction of motion.","url":"https://doi.org/10.1115/imece1997-0433","authors":["Osamah M.

Cascade control has the ability to accelerate, additionally stabilize, and reduce oscillations, which are all extremely important in systems such as a tendon-driven compliant actuators with elastic transmission. Inner-loop controllers are closed in terms of motor positions, and outer-loop controllers in terms of actuator position and estimated stiffness. The dominant dynamics of the system (position and stiffness), composed of the mechanical part and inner loops, are identified by a closed-loop auto-regressive with exogenous input (ARX) model. The outer-loop controllers are tuned on the basis of experimentally identified transfer functions of the system in several nominal operating points for different stiffness values. After the system is identified, a controller bank is generated in which a pair of actuator position and stiffness controllers correspond to a nominal operating point and covers the area surrounding the nominal point for which it is designed. The controllers used are integral-proportional differential (I-PD) and integral-proportional (I-P) controllers, which are a variation of the PID and PI controllers with dislocated proportional and derivative gains from a direct to feedback branch that result to no overshoot for even fast reference changes (i.e., step signal), which is essential for preventing tendon slackening (meeting the pulling constraint). Analytical formulas for controller tuning based on only one parameter, λ, are also presented. Since position and stiffness loops are decoupled, it is possible to change λ for both loops independently and adjust their performance separately according to the needs. Also, the controller structure secures the smooth response without overshooting step reference or step disturbance signal, which make practical implementation possible. After all the controllers were designed, the cascade control structure for simultaneous position and stiffness control was successfully evaluated in a laboratory setup. Thus, the presented control approach is simple to implement, but with a performance that ensures a pulling constraint for tendon-driven actuators as a foundation for bioinspired antagonistic VSAs.","url":"https://doi.org/10.3389/fnbot.2019.00069","authors":["Branko Lukić","Kosta Jovanović","Tomislav B.

We further evaluated the motion stability of the robot.

However, Minimally Invasive Surgery (MIS) eliminates this tactile feedback, creating a critical sensory gap. To address this, the EU Horizon project PALPABLE is developing novel fiber-optic sensing modalities for stiffness assessment. Successful integration of this technology requires an articulation interface that balances high maneuverability with the structural stability necessary for deflection-free tissue palpation. We present a single-degree-of-freedom (DOF) soft silicone actuator integrated with a modular, bioinspired passive stiffening element. Mechanical loading tests, motion tracking, and Finite Element Method (FEM)-guided design iterations validate the stiffening strategy and actuator performance. The design achieves a substantial increase in bending stiffness, improving the stiffness-pressure response by 8-fold relative to the unstiffened actuator under critical loading (normal force at a 90&#xb0; bend). Furthermore, we developed a compact, custom pneumatic syringe pump with closed-loop pressure control to ensure precise, safe operation in surgical environments. By combining embedded fiber-optic sensing with machine-learning models, the system achieves free-space full-shape reconstruction with approximately 1% error.

The SMA wires are used to drive the actuator to achieve bending, while the high elastic wire's elasticity is used to achieve recovery. The actuator is cast into a lattice structure with five connection nodes, named Lattice-N5. Lattice-N5's fast response properties are validated through finite element analysis and experiments.

Motivated by role allocation across gait phases in animal legs, where in-air positioning requires far less actuation effort than ground contact support and force modulation, this work proposes a novel gas-oil hybrid servo actuator, denoted GOhsa, for quadruped knee joints. GOhsa utilizes pre-charged high-pressure gas to pressurize hydraulic oil, converting the conventional dual-chamber pressure servo control into a single-chamber configuration while preserving the original piston stroke. This architecture enables bidirectional position-force control, enhances energy regeneration applicability, and improves operational efficiency. Theoretical modeling is conducted to analyze hydraulic stiffness and frequency-response characteristics, and a linearization-based force controller with dynamic compensation is developed to handle system nonlinearities. Experimental validation on a single-leg platform demonstrates significant energy-saving performance: under no-load conditions (simulating the swing phase), GOhsa achieves a maximum power reduction of 79.1%, with average reductions of 15.2% and 11.5% at inflation pressures of 3 MPa and 4 MPa, respectively. Under loaded conditions (simulating the stance phase), the maximum reduction reaches 28.0%, with average savings of 10.0% and 9.8%. Tracking accuracy is comparable to traditional actuators, with reduced maximum errors (13.7 mm/16.5 mm at 3 MPa; 15.0 mm/17.8 mm at 4 MPa) relative to the 16.6 mm and 18.1 mm errors of the conventional system, confirming improved motion stability under load.

While soft pneumatic actuators provide a foundation for soft robotics-based systems, achieving biomimetic functionality requires control strategies that address both contraction motility precision and compliant interaction dynamics. In this study, we integrate admittance control with finite-time state-dependent Riccati equation (FT-SDRE) and propose a compliant and robust combined force and displacement control for a soft actuator used in robotic gastric simulator. This approach enables a more biomimetic simulation of smooth muscle in gastrointestinal (GI) system when the actuators contact the contents and can help reduce excessive stress on the soft actuator. A three-phase contact model is proposed to describe the force-deformation behavior of the actuator while interacting with the contents, followed by experimental validation. The novel admittance-controlled FT-SDRE enhances both safety and physiological realism in soft tissue interaction. Experimental validation was conducted using three objects: an irregular-shaped gelatin sample, a regular-shaped gelatin sample (same material, different geometry), and an air-filled latex balloon. Compared with nonadmittance FT-SDRE control, the admittance-controlled FT-SDRE reduced 11.19% to 38.46% average contact force according to different objects. Across all tests, the time spent above a force threshold was reduced by 35-39%, which highlights the potential of the proposed method to improve safety, adaptability, and biomimicry in next-generation in vitro gastric simulation platforms.","url":"https://doi.org/10.1177/21695172251415290","authors":["Jiang S","Kazemi S","Stommel M","Cheng LK","Xu W"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1177/21695172251415290","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"doi:10.3389/frobt.2026.1798227","name":"Automated capture and transfer of human facial expressions to humanoid robots for realistic patient simulation.","source":"pubmed","abstract":"Realistic reproduction of human facial expressions is essential for realistic interactions between humans and humanoid robots.

A user study (n = 40) evaluated emotion recognition across three stimulus categories: human faces (H), unconstrained virtual avatars (A) and humanoid robots with limited facial actuation (R).

Highly expressive emotions such as surprise (H: 87.5%; A: 57.5%; R: 65%) and fear (H: 45%; A: 27.5%; R: 57.5%) achieved moderate recognition rates, whereas subtle emotions such as anger (H: 65%; A: 40%; R: 12.5%) and disgust (H: 60%; A: 10%; R: 22.5%) were poorly recognized on the robot.

While electrical actuation systems have achieved autonomy through battery power and wireless control, pneumatic actuators remain tethered to air supply sources. Liquid-to-gas phase change actuators utilizing low-boiling-point liquids offer a potential solution, though they typically require substantial thermal input through heating elements that maintain electrical dependencies. External heat sources, particularly light energy, present an alternative for terrestrial applications. However, despite their optical transparency, silicone-based materials have a high volumetric heat capacity and low thermal conductivity, which limits efficient photothermal energy transfer. Previous attempts to address this issue through the incorporation of graphene or metallic powder have compromised material properties, including reduced transparency and altered elastic moduli. Inspired by the tapetum lucidum structure found in the eyes of nocturnal animals, which enables efficient light utilization in low-light conditions, this study proposes a novel anisotropic bilayer soft actuator incorporating Laser-Induced Graphene (LIG) on the inner surface of the light-irradiated silicone layer. This creates an anisotropic structure with enhanced photothermal conversion capabilities while maintaining the advantageous properties of silicone. Comparative analysis demonstrates that the proposed actuator exhibits significantly higher photo-induced bending efficiency than conventional silicone-based actuators. The response time improved by 54%, decreasing from 142 s for pure silicone to 65 s, with recovery response time showing a 48% improvement. This design maintains the silicone's transparency and flexibility while utilizing LIG, which can be fabricated under ambient conditions, facilitating manufacturing and diverse applications.","url":"https://doi.org/10.1177/21695172251399631","authors":["Sogabe M","Kim Y","Miyazako H","Kawashima K"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1177/21695172251399631","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"doi:10.3390/biomimetics11060360","name":"A Biomimetic Four-Chamber Soft Actuator for Human-like Dexterous Manipulation with Spatial Bending and Twisting Capabilities.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics11060360","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.3390/biomimetics11060360","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1002/advs.202513881","name":"LEGO-like Origami Robots Standardize Structure Design of Soft Robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/advs.202513881","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1002/advs.202513881","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1177/21695172251394599","name":"Origami Actuator with Tunable Limiting Layer for Morphological Adaptive Soft Robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1177/21695172251394599","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1177/21695172251394599","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.3389/frobt.2026.1761507","name":"Design and evolution of a triad twisted string actuator for controlling a two degrees of freedom joint: improving performance and simulating active transmission adjustment.","source":"europepmc","abstract":"Actuated universal joints are used in a wide range of robotic applications, including mobile snake robots, snake-arm robots and robotic tails.

To realise the benefits of inline actuation while keeping the system compact with a high power to weight ratio, an actuated universal joint (AUJ) was developed using an ‘‘antagonistic triad’’ of three twisted string actuators in our previous work. However, the design had numerous drawbacks in its prototype form, namely, a limited angle range, poor accuracy due to the angular feedback sensors used, and issues with string failure due to mechanical design choices. In this publication, we performed a root-cause analysis of these issues, and partially or fully mitigated some of them by reducing the distance between the twisted string actuator (TSA), removing geometry which caused premature string failure, and exchanging the angular feedback sensors for more accurate ones. As a result, angle range was increased from ± 14.5° to ± 26° for a single axis, and ± 6° to ± 20° for a dual axis movement. Angular feedback sensor accuracy increased from ± 0.21° to ± 0.11°, and no string failures occurred within load limits. The performance of the mechanism was further characterised with additional experiments for increased follower load and angular velocity.

As a typical representative of amphibians, sea turtles can not only crawl on land but also have excellent underwater movement ability, which is an important source of inspiration for amphibious bionic robots. However, due to a lack of high-performance soft actuators, suitable bionic structure designs, and effective control methods, most of the current bionic turtle robots actuated by smart materials can only demonstrate movement in a single medium (e.g., swimming in water or crawling on land). Here, an amphibious turtle robot actuated by bionic muscles that can achieve effective movements in two media was designed. To enhance the amphibious ability of the turtle robot, a cylindrical dielectric elastomer actuator that can adapt to a variety of environments is designed with a maximum bidirectional deformation (±65°) and a high output force (∼80 mN). By optimizing the motion trajectory of the fins and programming the phase control of multiple bionic muscles, the robot's maximum swimming speed reaches 0.4 BL/s. In addition, the robot can realize different motion modes, such as forward, backward, lateral movement, turning, and crawling. Finally, the high mobility and environmental adaptability of the turtle robot are demonstrated in an L-shaped swimming passage and in two mediums (transition from land to water).

Among soft robotic components, soft pneumatic actuators (SPAs) are particularly relevant for applications such as packaging and agricultural harvesting. However, the role of geometric parameters in governing actuator performance remains insufficiently understood. This study introduces a novel geometric parameter for SPAs, focusing on chamber wall thickness and the number of air pillows, to establish predictive relationships between design and performance. A nonlinear finite element analysis model, calibrated with a Yeoh third-order hyperelastic material law obtained from uniaxial tensile tests of silicone rubber, was employed to simulate actuator deformation and stress distribution under pressures from 10 to 90 kPa. The results show that reducing chamber wall thickness increases deformation but reduces structural stability, while increasing the number of pillows enhances bending flexibility but lowers stiffness. To validate the simulations, SPAs were fabricated using silicone casting with 3D-printed molds and tested under controlled laboratory conditions. Experimental measurements of elongation and bending closely match finite element predictions, confirming model accuracy. Furthermore, load-handling experiments demonstrated that the optimized two-finger gripper, equipped with the proposed actuators, could reliably grasp irregularly shaped products without damage. These findings highlight the importance of geometric parameter selection in SPA design and demonstrate the feasibility of deploying such actuators in industrial loading/unloading systems. The integration of experimental validation with simulation provides a robust framework for advancing soft robotic grippers toward practical, scalable applications.","url":"https://doi.org/10.21203/rs.3.rs-9566218/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.21203/rs.3.rs-9566218/v1","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1038/s41598-025-25631-y","name":"Performance of a bionic Carangidae robot fish based on a dielectric elastomer material.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-25631-y","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1038/s41598-025-25631-y","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1038/s41467-025-65228-7","name":"Tailoring conductive nanofiller alignment for high actuation strain and output force in electroactive polymers.","source":"europepmc","abstract":"An intrinsic conflict between high deformability and rigidity hinders the development of electroactive polymer (EAP)-based soft robots. Here, we employ an external electric field to align Al2O3-coated carbon nanotubes (Al2O3@CNTs) in a poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene) (P(VDF-TrFE-CTFE)) matrix. Compared with pure P(VDF-TrFE-CTFE), the thickness strain of nanocomposites with horizontally and vertically aligned Al2O3@CNTs increases by 473% and 814%, respectively. It results in a high bending angle up to 215° for their actuator beams. Importantly, the horizontally aligned Al2O3@CNTs enhance the local stiffness via ‘face-enhanced effect’, yielding a high output force per unit volume (1.25 mN/mm3 at 30 V/μm). It is not only ~346% higher than pure P(VDF-TrFE-CTFE) but also higher than the reported ceramic actuators. Accordingly, the soft robots made by the designed nanocomposite actuators could climb slopes up to 52° and carry loads equivalent to eight times their body mass. Consequently, this modulating strategy develops a high-performance actuation for soft robots. Electroactive polymers can be used for soft robotics, though it is challenging to balance rigidity and deformability.

Efficiency depends on selecting and engineering responsive materials that directly transform environmental stimuli into mechanical actuation and motion, or harvest and store environmental energy to power actuators. Thermo-responsive materials undergo shape changes with temperature variations, while hygroscopic materials leverage moisture adsorption to induce actuation. Photothermal materials convert sunlight into heat and can combine thermal or hygroscopic actuators for controlled deformation. Osmotic processes drive movement through fluidic interactions, whereas pH-sensitive hydrogels respond to chemical gradients, facilitating controlled motion. Triboelectric materials generate electricity via contact-induced charge transfer, enabling self-powered sensing and actuation, while wind-dispersed structures exploit aerodynamic forces for unique movements. This review explores the critical roles of chemical, physical, mechanical, and environmental properties of materials in designing soft robots for sustainable and autonomous operation. Importantly, the review distinguishes between the broad concept of environmental energy and operation that is energetically sustainable. It systematically evaluates reported actuators and soft robotic systems based on whether their required energy sources and operating conditions are naturally occurring and regenerable, or instead depend on restricted environmental ranges, auxiliary inputs, or laboratory-controlled conditions. By examining material behavior, integration into multifunctional composites, and mechanism design for exploiting sustainable energy, this review identifies both established and emerging pathways toward environmentally realistic, autonomous, and long-lived soft robotic systems, with potential applications in environmental monitoring, reforestation, and other robotic domains.","url":"https://doi.org/10.1021/acs.chemrev.5c00258","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1021/acs.chemrev.5c00258","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s25247532","name":"Extended Dynamic Model for the UR16e 6-Degree-of-Freedom Robotic Manipulator.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25247532","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.3390/s25247532","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41598-026-63913-1","name":"Simulation study on prescribed-time stabilization of 5-DOF exoskeletons using a regularized super-twisting approach.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-026-63913-1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1038/s41598-026-63913-1","updatedAt":"2026-08-31T06:34:19.809Z"},{"id":"doi:10.3390/mi17040471","name":"A Compliant SMA-Actuated Capsule Robot with Integrated Locomotion and Steering for Wireless Capsule Endoscopy.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi17040471","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.3390/mi17040471","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10120816","name":"Biomimetic Artificial Muscles Inspired by Nature's Volume-Change Actuation Mechanisms.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10120816","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.3390/biomimetics10120816","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1177/21695172251405996","name":"A Stiffness-Tunable Soft Actuator with Adjustable Jamming for Dexterous Manipulation.","source":"europepmc","abstract":"In this work, we introduce the Jamming Adjustable PneuNet Actuator (JAPA), a novel soft robotic finger that enables both stiffness modulation and tunable bending behavior through a flexible hybrid jamming approach.

Meanwhile, the granular jamming element distributed throughout the finger can provide adaptive stiffness reinforcement across all bending configurations. The combination of adjustable stiffness and reconfigurable bending profile substantially enhances JAPA’s multidirectional force control and dexterity. To evaluate its performance, we conducted a series of experiments to assess JAPA’s stiffness modulation, pull-off and output forces, multidirectional force control, and workspace. Experimental results demonstrate that JAPA can achieve a maximum stiffness gain of up to 3.55×, with adjustable stiffness distribution contributing to a workspace expansion exceeding 200% and a more than 300% improvement in multidirectional force modulation. To visualize its multidirectional force control ability, we used a single JAPA unit to operate a computer cursor via a TrackPoint, dragging the cursor in different directions.

However, a mismatch between the knee-to-CoM transmission ratio and jumping demands, together with power-loss-induced motor performance degradation at high speeds, shortens the high-power operating window and limits jump performance. To address this, this paper introduces a variable-reduction-ratio knee-joint paradigm in which the reduction ratio is coupled to the joint angle and decreases during extension. Analysis of motor output and knee kinematics motivates coupling the reduction ratio to the joint angle. A high initial ratio increases the takeoff torque, and a gradual decrease limits motor speed and power losses, extending the high-power window. A linear-actuator-driven guide-rod mechanism realizes this strategy, and parameter optimization guided by explosive jump control is employed to select the design parameters. Experimental validation demonstrates a high jump of 0.63 m on a single-joint platform (a theoretical improvement of 31.9% over the optimal fixed-ratio baseline under the tested conditions).

We introduce a novel, single-actuator continuum robot inspired by the terrestrial locomotion of the gray bichir ( Polypterus senegalus ), which employs a simple rotating helix to reproduce realistic undulatory movements. We hypothesized that a simplified robotic model with minimal actuation could accurately replicate the terrestrial locomotion patterns observed in P. senegalus . Using a ‘robot-twin’ methodology, we developed four helix configurations directly informed by the observed gait postures of real fish specimens and compared robotic performance and kinematics against biological data. We found that helix geometry significantly influenced both locomotion speed and lateral stability, with designs closely mimicking biological curvatures often exhibiting trade-offs between accuracy and performance. The fastest helix configuration produced the greatest lateral oscillation, whereas the most biologically accurate shape resulted in reduced locomotion efficiency. Additionally, integrating passive leg structures greatly enhanced stability, mirroring the biomechanical function of pectoral fins in the real fish.

Here, we report electrofluidic fiber muscles, soft artificial muscles for robotic applications with power density comparable to skeletal muscles (50 watts per kilogram), contraction strains of 20%, and response time of 0.3 second. These 2-millimeter-thick muscles comprise antagonistic fluidic actuators driven by electrohydrodynamic fiber pumps in a closed circuit.

We demonstrated that performance is increased by pre-pressurizing the muscles at an optimal bias pressure. Applying bias pressure allowed the antagonist actuator to act as a reservoir for the agonist, enabled 200% higher operating voltages by preventing cavitation, and leveraged the nonlinear pressure-stroke response of the actuators, increasing strain threefold at a given pump pressure. We characterized and modeled their dynamics, identifying optimal bias pressures. Electrofluidic muscles scale by simply bundling fibers.

By leveraging the multifunctional properties of thermoplastic polyurethane (TPU), including inherent flexibility, fusibility, and translucency, and employing a desktop-level fused deposition modeling printer, airtight chambers and embedded optical waveguides are realized within a continuous printing process. Optimized printing parameters lead to fully densified chambers, resulting in a leakage rate of only 0.85% under 200 kPa and maintaining 462.55 kPa after 10 minutes from an initial 500 kPa. The optical waveguides exhibit robust proprioception, maintaining a stable signal over 5000 bending cycles with less than 0.5% drift. Mechanical tests confirm synchronized deformation and continuous structural integration across the monolithically co-printed actuator-sensor region, enabling MPPPAs to achieve reliable actuation-sensing performance with sensing errors below 1.82%. Demonstrations include precise surface contour measurement with the root mean square error of 0.16 mm and real-time gripping width estimation, validating the method's effectiveness in fabricating compact and stable proprioceptive actuators.

The tracking error, adaptive weighting dynamics and disturbance dynamics are coupled together to form a composite Lyapunov function, which guarantees Global Uniform Ultimate Boundedness (GUUB); when the approximation residuals are small enough, Global Asymptotic Stability (GAS) can be achieved. Three benchmark paths of lemniscate, circle, and diamond were simulated in large scale. The final error of position was less than 4&#xa0;cm on all the trajectories.

However, fundamental questions remain unresolved: What neural mechanisms drive this behavior, and what functional benefits does this behavior offer? Specifically, is intermittent swimming more energy efficient than continuous swimming, and, if so, by what mechanism? Live-animal experiments pose technical challenges, because observing or manipulating internal physiological states in freely swimming animals is difficult. Hence, we developed ZBot, a bioinspired robot that replicates the morphological features of larval zebrafish. Embedding a network model inspired by neural circuits and kinematic recordings of larval zebrafish, ZBot reproduces diverse swimming gaits of larval zebrafish bout-and-glide locomotion. By testing ZBot swimming in both turbulent and viscous flow regimes, we confirm that viscous flow markedly reduces traveled distance but minimally affects turning angles. We further tested ZBot in these regimes to analyze how key parameters (tail-beating frequency and amplitude) influence velocity and power use. Our results show that intermittent swimming lowers the energetic cost of transport across most achievable velocities in both flow regimes. Although prior work linked this efficiency to fluid dynamics, like reduced glide drag, we identify an extra mechanism: better actuator efficiency. Mechanistically, this benefit arises because intermittent locomotion shifts the robot's actuators to higher inherent efficiency. This work introduces a fishlike robot capable of biomimetic intermittent swimming-with demonstrated energy advantages at relevant speeds-and provides general insights into the factors shaping locomotor behavior and efficiency in aquatic animals.","url":"https://doi.org/10.1126/scirobotics.adw7868","authors":["Liu X","Longchamp FA","Zunino L","Gevers L","Schneider LR","Bothner SI","Guignard A","Crespi A","Bellegarda G","Bernardino A","Naumann EA","Ijspeert AJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1126/scirobotics.adw7868","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"doi:10.1002/adma.202510298","name":"Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/adma.202510298","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1002/adma.202510298","updatedAt":"2026-08-31T06:34:19.809Z"},{"id":"doi:10.1021/acsnano.5c17835","name":"Magnetic Joint-Mediated Assembly of Optically Actuated Soft Robots with Adaptable Modal Switching.","source":"pubmed","abstract":"Soft robots based on optically responsive smart materials have attracted extensive research interest for their unique capabilities.

The gripper actuates within two seconds at 80&#x2009;kPa, exerts up to 6&#x2009;N of pulling force, and lifts objects up to 1&#x2009;kg-more than 16 times its own weight. Its workspace expands from 200&#x2009;mm&#xb2; to 14,000&#x2009;mm&#xb2;, enabling the handling of fruits with diverse shapes and sizes. Each finger bends up to 240&#xb0;, with performance closely matching finite element predictions. For vision measurements, the hue channel in the HSV color space enables robust real-time color detection, achieving 100% shape classification accuracy and a size measurement error below 1.8%. Tactile sensors distinguish soft from firm objects, while curvature sensors accurately measure the finger's bending state-both based on optical signal loss. Real-time demonstrations validate the system's ability to assess ripeness using multimodal data (vision, tactile, and curvature) and successfully harvest greenhouse strawberries with minimal damage. This platform offers a versatile, sensor-rich solution for both precision agriculture and general-purpose robotic manipulation.","url":"https://doi.org/10.1038/s41467-026-70588-9","authors":["Mishra AK","Ramaswami A","Shree V","Ilman MM","Ly KD","Pritts MP","Shepherd RF"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1038/s41467-026-70588-9","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.3390/s26092740","name":"Model Predictive Control-Based Assist-as-Needed Strategy for Reducing Motor Slacking in Robot-Assisted Rehabilitation.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26092740","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.3390/s26092740","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1371/journal.pone.0333187","name":"Design and control of a novel pneumatic soft robot based on the improved particle swarm optimization algorithm.","source":"europepmc","abstract":"","url":"https://doi.org/10.1371/journal.pone.0333187","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1371/journal.pone.0333187","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3389/frobt.2026.1778864","name":"Evaluation of material effects on three-dimensional cultured skeletal muscle cells for biohybrid robots.","source":"europepmc","abstract":"Robots are traditionally confined to controlled environments such as factories, where human interactions are limited. However, the demand for robots that are capable of collaborating with humans is increasing. To achieve symbiosis, integrating the physical flexibility and environmental adaptability of living organisms into robotic systems is crucial. An example of such a robot is a biohybrid robot driven by three-dimensional (3D) cultured skeletal muscle cells. These muscle cells, which are composed of myoblasts and an extracellular matrix (ECM), contract and generate force in response to external stimuli. The standardization of such 3D-cultured skeletal muscle cells is essential for practical applications. However, their complete standardization has not yet been achieved. The contractile force of 3D-cultured skeletal muscle cells produced via 3D printing is still insufficient for practical applications as actuators in biohybrid robots. In a previous study, we developed a simple fabrication method for 3D-cultured skeletal muscle cells. These bio-cultured artificial muscle (BiCAM) cells can control the shape and cell alignment of tissues. Differences in the composition of an ECM have been suggested to affect the contractile force of 3D skeletal muscle tissues; however, their impact on the response characteristics remains poorly understood. In this study, we investigated how the ECM composition influences the contractile force of 3D skeletal muscle cells in biohybrid robots as a step toward their eventual standardization. Compared with tissues cultured under MF conditions, in which electrically induced contraction was previously confirmed, tissues cultured under CM conditions exhibited an approximately two-fold greater contractile force at voltage amplitudes of 10 and 30 V. Furthermore, the fabrication success rate was 100 % under CM conditions but only 62.5-70 % under other ECM conditions. In contrast, although CM tissues generated larger forces, tissues cultured under MgF and CMg conditions exhibited higher-frequency response. These findings demonstrated that the BiCAM is a viable actuator and offers new possibilities for the design of biohybrid robots.","url":"https://doi.org/10.3389/frobt.2026.1778864","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.3389/frobt.2026.1778864","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41598-026-42181-z","name":"Design of an in-pipe inspection robotic system (IPIRS) with YOLOv8-LSTM integration for real-time in-pipe navigation.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-026-42181-z","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1038/s41598-026-42181-z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1126/sciadv.aea3712","name":"A general soft robotic controller inspired by neuronal structural and plastic synapses that adapts to diverse arms, tasks, and perturbations.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.aea3712","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z","doi":"10.1126/sciadv.aea3712","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"pmid:42555738","name":"Sharp nanothorn-equipped ionogel microrobots for targeted periodontitis therapy.","source":"pubmed","abstract":"Periodontitis necessitates targeted therapy due to its high prevalence, progressive tissue destruction, and systemic disease links.

Biological fish achieve this by utilizing their lateral line sensory systems to perceive local flow gradients and adopting an energy-efficient swimming pattern known as the K&#xe1;rm&#xe1;n gait. To translate this biological phenomenon into a practical robotics engineering solution, this paper proposes a fully computational framework focusing on the modeling and simulation of a spatio-temporal sensory system to autonomously generate the K&#xe1;rm&#xe1;n gait. To overcome the unrealistic assumption of full-state observability common in existing reinforcement learning studies, we model a multi-point lateral line array coupled with a frame-stacking mechanism. This allows the simulated agent to reconstruct the spatio-temporal topology of the surrounding unsteady flow relying exclusively on local pressure and velocity gradients. The sensory model is integrated with a spatio-temporal perceptual twin delayed deep deterministic policy gradient (STP-TD3) algorithm, which drives a Hopf-oscillator-based central pattern generator. Through rigorous high-fidelity computational fluid dynamics simulations, we quantitatively evaluate the autonomous emergence of the K&#xe1;rm&#xe1;n gait by assessing the agent's kinematic energy proxy-mapped from joint actuation effort. Results reveal that the agent expends significantly less mechanical effort navigating through the turbulent vortex street compared to swimming in steady water, suggesting the active exploitation of the local wake dynamics.

In the forward setting, the framework predicts continuous energy landscapes with coefficients of determination above 0.99 and barrier errors below 0.1%.

For anthropomorphic robotic hands, this combination is useful in a very direct sense: the actuator must fit into a compact structure while still producing compliant finger motion. However, the coupled electro-thermal-mechanical response of TCP materials makes internal-state estimation difficult. It also complicates coordinated multi-finger actuation, especially when additional sensors cannot be easily embedded in a soft hand without increasing size, wiring complexity, or structural redundancy. In this work, we develop a synergistic control framework with temperature self-sensing for regulating multiple TCP actuator arrays in a soft dexterous hand. Electrical and mechanical signals are collected through an integrated sensing architecture, after which principal component analysis (PCA) is used to establish a low-dimensional relationship between input power commands and finger bending trajectories. To make the actuator response more tractable, the total contraction force is divided into a temperature-dependent component and a mechanical component. On this basis, a predictive thermal regulation model is constructed, allowing the TCP arrays to be controlled without relying on external temperature sensors. The framework was evaluated in Feix grasp-maintenance and grasp-transition experiments. Across three representative grasp-maintenance tasks with five repeated trials per condition, self-sensing control reduced the mean fingertip dispersion by 37.5-42.1% in the X direction and by 8.1-14.7% in the Y direction compared with open-loop actuation. The corresponding planar fingertip dispersion decreased by 16.3-36.5%. During grasp transitions, Dz changed by 1.4-30.7% across the four transition tasks, with pronounced reductions in Feix-09-10 and Feix-26-27-28, whereas Feix-12-13-14 showed only a small reduction.

This review synthesizes emerging research from the perspective of sensor-driven control systems, defined as systems in which sensing is substantively linked to monitoring, estimation, supervision, planning, decision-making, or actuation. Rather than treating LLMs as generic intelligent agents, the review examines their position within the sensing-decision-control chain and their interaction with state representations, supervisory logic, human operators, external tools, and classical control components. The paper develops a functional taxonomy of LLM roles based on proximity to actuation, grounding requirements, and deployment risk. This taxonomy reveals a clear maturity gradient: interpretive, supervisory, diagnostic, and engineering-support roles are currently the most credible and deployable, whereas runtime control participation remains the least mature and highest-risk form of integration. The analysis further shows that reliable implementations are predominantly hybrid. In such architectures, LLMs function as semantic and orchestration layers that augment, rather than replace, classical sensing, estimation, planning, and control. Key integration patterns include sensor-to-semantics pipelines, retrieval-augmented generation, tool use, agentic workflows, closed-loop refinement, and safety-aware mechanisms. Persistent challenges-including hallucination, weak physical grounding, latency, cybersecurity risks, and the lack of formal guarantees-highlight the need for rigorous operational evaluation and realistic benchmarks. The review concludes that LLMs are most credible as interpretive, supervisory, diagnostic, and human-facing intelligence layers embedded within hybrid architectures.

Therefore, this work proposes a smooth-motion walking-type piezoelectric actuator over a large travel range with high torque inspirited by the bipedal walking mechanism. The driving legs with high stiffness and large displacement of the actuator are divided into two groups; by imitating the bipedal walking gait of humans, the driving trajectories of the two sets of driving legs are alternately integrated to adjust the balance between the driving torque and the resistance torque, ensuring that the resultant force torque acting on the rotor is zero, thereby achieving smooth motion in a large travel range with high torque. The multi-objective optimization algorithm of the neighbourhood cultivation genetic algorithm (NCGA) is adopted to optimize the structure design of the driving legs by considering the stiffness and displacement, in order to achieve the balance of high stiffness and large displacement at the foot end of the driving leg. The linear fitting coefficients of the output displacements of the actuator all reach above 0.999, the resolution is 0.4 &#xb5;rad, and the maximum output torque is better than 1.31 N&#xb7;m.

This paper proposes an offline-to-online planning and whole-body control framework for robust in-place jumping of full-sized humanoid robots. The framework integrates phase-consistent offline trajectory optimization, lightweight online reference reshaping, constraint-aware whole-body control, and actuator-level command mapping to improve execution robustness without online re-optimization. In the offline stage, centroidal-dynamics-based trajectory optimization generates jumping references subject to kinematic-consistency and contact-feasibility constraints. During execution, these references are adapted online using real-time state estimates to compensate for takeoff deviations and regulate the landing state; a weighted quadratic-programming whole-body controller then tracks the adapted references. Hardware experiments on a 79.5 kg humanoid robot demonstrate repeatable in-place vertical jumps with a height of approximately 30 cm and stable landings.

Conventional active grippers struggle to achieve rapid response and reliable locking simultaneously due to sensing delays, actuation latency, and impact vulnerability. To address this challenge, this paper presents an aerial docking system that integrates mechanical design and flight control, built around a Bistable Tension-Hinge Gripper (BTHG). By incorporating morphological intelligence, the BTHG utilizes the collision impact to cross an elastic energy barrier. This triggers a rapid snap-through instability that forces the mechanism into a securely locked state. This purely passive locking process eliminates the need for continuous power or active feedback during the transient contact phase. Furthermore, the outwardly flared geometry of the gripper enlarges the capture region. Its compliant structure also absorbs collision shocks to protect the UAV during rapid physical contact. Bench tests demonstrate that the prototype completes the locking transition in 0.16 s and provides a maximum holding force of 54.8 N. When integrated with onboard perception and a PX4/ROS2 flight control framework, the BTHG enables a fully autonomous docking pipeline at approach speeds up to 1.4 m/s. This pipeline seamlessly covers visual target detection, agile approach, and passive locking. By shifting the highly dynamic contact response from active software control to physical hardware design, this work enables UAVs to perform reliable dynamic docking.

Origami-based designs are particularly attractive owing to their capacity for large deformations, programmable geometry, and kinematic reconfigurability. In existing active origami, however, stimuli-responsive materials are embedded only in the narrow crease regions, and therefore actuating capability and mechanical performance are predominantly governed by crease rotation, limiting the achievable folding ratio and performance tunability. To overcome these limitations, curved-crease origami is newly introduced as an active metamaterial design wherein folding is driven through panel bending. Folding kinematic analyses demonstrate that the elastic strain energy of the panels and creases is simultaneously minimized when circular arc creases are combined with orthogonal generators. Building on this geometric principle, a panel-driven actuation framework is established using high-modulus bimetallic strips. Further analysis confirms that this minimum-energy curved-crease origami configuration achieves a high conversion efficiency from actuation strain of material to active structural deformation strain. Circular sheets with curved zigzag patterns are then proposed that exhibit predictable thermally induced self-folding from a planar sheet into a compact wrapped cylindrical shape. By introducing Euler spiral creases, self-wrapping over multiple turns is realized with an area folding ratio of up to 19.1. Further extension to multilayer architectures yields active metamaterials that demonstrate three-dimensional shape transformations. The coupling of a soft mode dominated by crease folding and a stiff mode involving simultaneous crease folding and panel bending enables a stiffness tunability spanning three orders of magnitude, the widest range in active metamaterials to date. Therefore, this work broadens the design space of active metamaterials and offers new opportunities for applications in soft robotics, deployable structures, and medical devices.","url":"https://pubmed.ncbi.nlm.nih.gov/42478276/","authors":["Chai S","Ma J","Zhang C","Xu W","Chen Y","You Z"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 21","addedAt":"2026-08-06T15:48:05.814Z"},{"id":"pmid:42475187","name":"Evaluation of a Portable EMG-Controlled Hand Exoskeleton With Independent Digit Actuation.","source":"pubmed","abstract":"Despite therapeutic efforts, the majority of individuals post-stroke will experience chronic motor deficits, particularly in the hand.

Activating a single muscle could significantly improve robustness beyond morphology, enabling recovery from 3 &#x2009; N m perturbations. Furthermore, synergistic reflex of biarticular muscles, especially hamstrings and gastrocnemius, extends the robustness to larger perturbations ( 5 &#x2009; N m ) . Our contribution highlights the synchronization of control strategies with the underlying morphological design through a universal sensory feedback signal, namely, GRF. These findings demonstrate the value of bio-inspired robots as testbeds to understand the potential principles underlying human motor control and support the transfer of such principles to legged robots and assistive systems.","url":"https://pubmed.ncbi.nlm.nih.gov/42460387/","authors":["Jiang Y","Murcia M","Yang J","Seyfarth A","Findeisen R","Sharbafi MA"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z"},{"id":"pmid:42457480","name":"Challenges for Developing a Soft Robotics Solution for the Surgical Treatment of Stress Urinary Incontinence in Women.","source":"pubmed","abstract":"Advances in soft robotics, smart materials and bio-interfacing may enable the development of implantable artificial muscles (IAMs) to replace or augment biological muscles. emPOWER, a UK Research Council engineering project, is initiating foundational technologies and proof of concept for IAMs. This expert opinion piece considers IAMs in the clinical context of stress urinary incontinence.

This work presents and evaluates a wireline, downhole-actuated pneumatic drilling architecture designed to directly mitigate these mission-ending risks through active wellbore pressure support and continuous cuttings removal within a single, sealed CO 2 circulation system. The proposed system combines a rotary-percussive bottomhole assembly with a deployable sealing membrane and a closed CO 2 pneumatic circuit that provides both mechanical support to the borehole wall and transport of generated cuttings to the surface. Reduced-order flow physics models are developed to capture compressible gas transport, particle entrainment, porous leak-off, junction losses, incompressible liquid tether flow, and phase-change thermodynamics. These models are assembled into section-wise drilling and cleanout cycles and integrated into a mission-level simulator that enforces realistic sol-level constraints on time, energy, battery usage, and working-fluid mass. Mission simulations demonstrate that cleanout operations dominate both energy and CO 2 mass budgets, establishing wellbore pressure support as a first-order design variable rather than a secondary constraint. Modest relaxation of the maintained back-pressure from an overburden-matched level to a derated fraction substantially reduces cleanout energy demand and idle leak-off penalties while preserving effective particle transport. Under an InSight/Mars Life Explorer-class mission envelope, the architecture exceeds a 30 m baseline depth target well within the nominal operational window, with favorable scaling toward &#x223c;100 m depths through increased mission duration and resource allocation. By explicitly coupling drilling, cuttings removal, and wellbore stability within a single operational framework, this architecture targets the primary failure modes identified in deep martian subsurface access.

Although several reviews exist in this domain, they primarily focus on applications, impacts, and trends, with limited attention to robot design in relation to affordability. Using a systematic literature review, this study identifies the features and capabilities commonly incorporated in low-cost social robots in educational contexts, as well as the design choices that balance effectiveness and affordability. Thirty-four (34) studies describing low-cost custom social robot designs were analysed following PRISMA guidelines.

The findings show that speech-based interaction (73.5%), vision capabilities (53%), and body-part movement (47%) are the most frequently reported features supporting learner-robot interaction. Additional features include expressive displays, touch input, and mobility. While 3D-printed housings are the most commonly adopted solution, alternative low-cost materials such as plywood and plush toys are also used. The use of smartphones as integrated computational and interaction platforms emerged as an innovative approach. Furthermore, commonly used sensors, actuators, and compute platforms are identified.

They use hyperelastic materials, such as silicone rubber, to generate large reversible deformations. However, it is not easy to model the mechanical behavior of silicone rubber under large deformations. It is difficult to accurately predict its nonlinear hyperelastic behavior and thus to accurately design and control these actuators. We have created an optimized Neo-Hookean constitutive model of Ecoflex 00-30 silicone rubber. This method is based on the combination of theory and experiments, whose goal is to enhance the usefulness of the model for performance analysis of soft actuators. Dumbbell-shaped specimens were tested in uniaxial tension on a ZQ-990LB testing machine in a controlled environment at 25.4 &#xb0;C and 57.4% relative humidity (RH). Stretch ratios varied between 1 and 8.6 and tensile speeds up to 500 mm/min were used. Stress-strain curves and fracture behavior were captured by the experiments. The Neo-Hookean model was then fitted and optimized using a global least-squares optimization approach. Two changes were made: piecewise segmentation of the data, and variable weight factors for uniaxial and equibiaxial tensile data. This accuracy was better for each of the stretch ratios. The optimized material parameters yielded curves that were in close agreement to the experimental data-significantly better than fitting using conventional single regime, particularly in each of the segmented ranges. The model breaks the range of deformations into segments, and in each segment it reflects the response of the silicone rubber to the various loadings. The results provide a good theoretical foundation for modeling the mechanics, analyzing the kinematics and developing intelligent control strategies for pneumatic soft actuators.

Network delay, temporary disconnection, and the use of single-point measurements may all reduce the ability of a system to respond to spatial variation in soil moisture and nutrient demand. In this work, an edge-controlled precision fertigation system was developed by combining multi-parameter soil sensing, spatial task scheduling, and a 6-DOF robotic manipulator. The ESP32 controller runs a preemptive FreeRTOS scheduler, allowing sensor acquisition, inverse-kinematics calculation, and pump actuation to be handled as separate tasks. A Kalman filter was used to smooth soil moisture measurements, and a hysteresis-based control strategy was adopted to reduce false triggering and repeated pump switching. To improve fertigation safety, a hardware-software interlock was added so that fertilizer delivery is always accompanied by water delivery. Hardware-in-the-Loop simulation and a 14-day field deployment were used to evaluate the system. The controller achieved an end-to-end latency of less than 38 ms and maintained operation during network interruptions through cached local parameters. After calibration, the robotic end-effector positioning error was reduced to &#xb1;2.4 mm. The hysteresis strategy lowered daily pump cycling by 71%. Based on prototype duty-cycle data and seasonal extrapolation, the projected seasonal water use and fertilizer demand were 44% and 38% lower, respectively, than those estimated for a uniform application. These values should be interpreted as model-based projections rather than direct season-long measurements. During 72 h of continuous operation, no Modbus faults were observed, and RTOS heap fragmentation remained stable. Overall, the results suggest that edge-based deterministic control can provide a practical route for precision fertigation where both spatial variability and intermittent connectivity must be considered.","url":"https://pubmed.ncbi.nlm.nih.gov/42451531/","authors":["Wang Z","Chen J","Zhao H","Wei B"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 6","addedAt":"2026-08-06T15:48:05.814Z"},{"id":"pmid:42451456","name":"Real-Hardware Deployment of a Nussbaum-Function PID Controller on a Current-Controlled Low-Cost Actuator via Hardware-Aware Optuna Tuning.","source":"pubmed","abstract":"Real-hardware deployment of adaptive manipulator controllers remains difficult because assumptions made in paper-level formulations are weakened by friction, encoder quantisation, current limits, communication latency, and low-speed actuation nonlinearities.

To isolate deployment-layer behaviour from the whole-arm Coriolis, centrifugal, and gravity dynamics, the study is centred on a single decoupled actuator (Dynamixel ID 6, distal wrist) under long-horizon sinusoidal tracking around a fixed operating region. A direct transfer of the baseline law is first reproduced and shown to degrade through cumulative adaptation-state growth, weakening of the Nussbaum modulation, and high internal command saturation. A hardware-oriented implementation is then evaluated that preserves the Nussbaum core while adding adaptation-state regularisation, low-speed velocity-reference feedforward, and tail-region damping; its parameters are selected through a hardware-aware Optuna archive of 79 real-hardware trials with hard rejection of unsafe runs and a score that jointly reflects tracking quality, internal command saturation, actuation activity, and bounded adaptation growth.

We investigate the magnetoelastic response of elastomeric micropillars containing superparamagnetic inclusions when actuated by a rotating magnetic field. Despite nominally identical geometries and forcing conditions, individual filaments display qualitatively distinct beating patterns, ranging from smooth periodic motion to abrupt snapping and bistable oscillations. Agreement between finite-element beam modeling and analytical theory, consistent with high-speed imaging data, demonstrates that these behaviors can arise from a magnetoelastic instability governed by a dimensionless control parameter comparing magnetic and elastic torques. This model indicates that near the instability threshold, small variations in micropillar composition, geometry, or magnetic field lead to large qualitative changes in dynamics, reflecting strong imperfection sensitivity characteristic of soft-matter bifurcations. Notably, the snapping transition produces brief episodes of high filament velocity, during which local Reynolds numbers approach unity. These transient inertial excursions contribute to the breaking of time-reversal symmetry and enhance net fluid transport, alongside other geometric and dynamic asymmetries in the filament motion.

As the field moves from laboratory prototypes toward clinical, industrial, and daily life deployment, research priorities are shifting from device-centered performance improvement to human-centered integration. This mini review provides a structured and critically oriented synthesis of exoskeleton technologies from four interconnected perspectives: technical architecture, technological paradigm evolution, deployment barriers, and future research directions. To improve transparency and reproducibility, we adopted a narrative review strategy with explicit literature selection criteria. Publications were identified from major scientific databases using combinations of keywords related to exoskeleton robotics, actuation, control, human-robot interaction, soft robotics, neural interfaces, rehabilitation, and wearable assistance. Representative studies were selected according to relevance, technical influence, clinical or engineering significance, and coverage of major technological paradigms. The review first analyzes three core technical dimensions-actuation systems, control strategies, and human-robot interaction which jointly determine the performance, adaptability, and usability of exoskeleton systems. Rather than only summarizing these technologies, we compare their trade-offs in terms of power density, control precision, compliance, energy efficiency, personalization, safety, and deployment readiness. The review then examines the evolution from rigid exoskeletons, which provide high structural support and precise force transmission, to soft exoskeletons, which improve compliance and comfort, and further to bio-integrated systems that combine neural interfaces, functional electrical stimulation, multimodal sensing, and mechanical assistance. Based on this synthesis, we organize the review using a Human-Exoskeleton Integration Maturity Framework spanning mechanical coupling, physical compliance, functional adaptation, and cognitive/bio-integrated coupling. Persistent barriers, including energy supply, personalization, safety assurance, cost, regulatory translation, and ethical governance, are critically discussed. Finally, future directions are outlined, including neural-interface-driven control, multimodal perception, human-in-the-loop optimization, hybrid rigid-soft architectures, and socially responsible design. Overall, this review argues that the next stage of exoskeleton development will depend not merely on stronger actuators or more intelligent algorithms, but on integrated systems that are adaptive, trustworthy, affordable, and seamlessly embedded in human movement and function.","url":"https://pubmed.ncbi.nlm.nih.gov/42434691/","authors":["Zheng L","Ramli R","Zhang W"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:05.814Z"},{"id":"pmid:42433609","name":"Bioinspired 0D mitochondrial bioenergetic actuators rewire cartilage progenitor cell metabolism for osteoarthritis remission.","source":"pubmed","abstract":"Mitochondrial dysfunction and consequent bioenergetic collapse in cartilage progenitor cells (CPCs), driven by excessive mitochondrial reactive oxygen species (ROS), constitute a fundamental barrier to endogenous cartilage regeneration and accelerate osteoarthritis (OA) progression. Accordingly, precise modulation of mitochondrial ROS is required to restore mitochondrial metabolic homeostasis. However, conventional antioxidant agents such as N-acetylcysteine (NAC) lack cell specificity and organelle-level precision, and exhibit limited bioavailability, thereby restricting their capacity to effectively reestablish mitochondrial metabolic homeostasis. Here, we engineer zero-dimensional (0D) bioinspired nanoassemblies, CPC membrane-coated (3-carboxypropyl)triphenylphosphonium bromide-functionalized NAC-derived carbon quantum dots (CM@TQDs), with capabilities for homotypic recognition and mitochondria-targeted metabolic reprogramming. Subsequently, CM@TQDs are encapsulated within ROS/pH-responsive hydrogel microspheres (HGCT), permitting inflammation-triggered release within the OA joint. Upon HGCT-mediated delivery and cellular internalization, the 0D nanoassemblies accumulate in mitochondria in a membrane potential-dependent manner, enhancing local mitochondrial bioavailability. Mechanistically, HGCT effectively scavenges mitochondrial ROS, restores oxidative phosphorylation, reestablishes tricarboxylic acid cycle flux, and suppresses aberrant glycolytic dependence. This metabolic restoration reactivates PI3K/AKT signaling, mitigates apoptosis and ferroptosis, and promotes CPC proliferation and chondrogenic differentiation. In vivo , HGCT attenuates synovial inflammation and enhances cartilage regeneration, markedly inhibiting OA progression.

However, traditional actuators suffer from contact friction and response delay; feedback and feedforward control alone have performance bottlenecks. As a result, the low-frequency tracking and mid-frequency isolation performance of CMG AVI are severely limited. Therefore, this paper proposes a magnetic levitation vibration isolation system (MLVIS) with composite control to optimize the tracking and AVI performance. In terms of structure, a magnetic levitation actuator is used to eliminate slow response and friction hysteresis. For the control algorithm, a composite strategy integrating integral force feedback and filtered-x recursive least squares is adopted. Through mutual compensation between the two control methods, this composite strategy mitigates the inherent time delay of feedback control and the instability of feedforward control. Experimental results show that the tracking error in the low-frequency band is 2.71% and 11.67% under single- and dual-frequency excitation, respectively, while 91.86% attenuation of the natural-frequency vibration amplitude is achieved in the mid-frequency band.

Emerging robotic platforms, MRI-compatible catheter systems, and MRI-native navigation frameworks indicate that MRI-guided endovascular robotics is moving beyond isolated feasibility concepts. Yet routine MRI-guided robotic endovascular procedures remain rare. This gap is not explained by the absence of a single enabling technology, but by the interaction of tightly coupled constraints spanning instruments, imaging and feedback, navigation, and system integration. In endovascular settings, these constraints are amplified by the need for miniaturized, flexible, and steerable tools operating under limited and phase-dependent feedback. This perspective argues that progress in MRI-guided endovascular robotics requires moving beyond compatibility-driven adaptation toward MRI-robot co-design. First, the emerging landscape of representative robotic platforms, MRI-compatible and MRI-actuated catheter systems, and MRI-navigation-enabling technologies is outlined. The coupled constraints that continue to limit translation are then analyzed, showing why component-level solutions often remain fragile when integrated into full procedural workflows. Building on this framework, four research axes toward MRI-native endovascular robotic systems are proposed: MRI-native instruments, MRI-native feedback, navigation under bandwidth-limited imaging, and integrated systems built through workflow-aware validation and benchmarking. Across these axes, the discussion emphasizes the importance of miniaturized actuation, robot-aware MRI pipelines, feedback-efficient shared control, realistic simulation, benchmarking, and workflow-aware validation.

In this study, high-resolution magnetic resonance imaging of 24 arms from Octopus bimaculoides was used to quantify the distribution of transverse, aboral, oral, and lateral internal longitudinal muscles, as well as the axial core housing the nerve cord. Results revealed a progressive increase in axial core area and a decrease in transverse muscle area from proximal to distal arm regions, while longitudinal muscle distributions showed no consistent trend. These anatomical insights informed the design of four soft arm models. Two models incorporated either uniform or octopus-inspired muscle group distributions, and the other two included an additional passive axial core. Using silicone rubber to mimic muscle mechanics, each design was evaluated via finite element analysis for tip displacement and arm curvature across various motions. The bioinspired model without an axial core achieved the greatest tip displacement, while the inclusion of the core reduced performance. Moreover, a parametric analysis of transverse-assisted bending demonstrated that even modest changes in the activation levels of transverse and longitudinal muscles can produce markedly different arm curvatures. This highlights how a bioinspired architecture can enable complex movements through simple modulation of relative muscle activation.

A retrofit prototype with a single powered knee joint was implemented to preserve the orthosis-like form factor while enabling personalized, impedance-controlled knee motion. Personalization was formulated in OpenSim as a kinematic optimization, where a low-dimensional knee-trajectory template was tuned using a sagittal foot-path objective, coordinate tracking, smoothness regularization, and feasibility constraints. The optimized trajectory was deployed during overground walking in one individual with SCI and compared within subject against a locked KAFO and a multi-joint exoskeleton. Relative to the locked condition, the personalized active-KAFO condition improved swing-phase outcomes, increasing step length by 38.6% and step height by 100.0%. It also reduced reliance on upper-limb support, with peak vertical walker force decreasing by 35.0%. Compared with the active KAFO, the exoskeleton showed similar step height (+&#x2009;2.2%) and swing speed (-&#x2009;10.2%), but greater limb progression, with step length increasing by 19.7%.

The ME-SOFS can be easily reconfigured and integrated to endow robots with somatosensory multiaxis force sensing capabilities. Based on fluid transduction, ME-SOFS converts applied force into mechanical output for fluidic actuators. We demonstrate this sensing-actuation loop in three scenarios: directional droplet manipulation, unified bending of cilia-like array guided by detected force vectors, and haptic feedback system that accelerates robotic grasping learning. ME-SOFSs demonstrate how fluidic approach can realize multiaxis force sensing for soft robots, and enable simplified, closed sensing-actuation loops and haptic human-machine interfaces.","url":"https://pubmed.ncbi.nlm.nih.gov/42418590/","authors":["Xie Z","Yu K","Wang P","Li S","Ling S","Qin Z","Zhang Y","Yang J","Zhang C","Zhang W","Xin W","Gu Y","Tan YJ","Laschi C","Tee BCK"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 10","addedAt":"2026-08-06T15:48:05.814Z"},{"id":"pmid:42418480","name":"Physically intelligent capsule robots with embodied memory and logic in the gastrointestinal tract.","source":"pubmed","abstract":"Miniaturized medical robots offer a promising solution for minimally invasive measurements and interventions in the gastrointestinal (GI) tract. Clinical assessment of GI disorders is commonly guided by threshold-based physiological indicators, including pressure, temperature, and pH, which motivate event-triggered strategies for personalized medicine.

Inspired by the autonomy of microorganisms that operate without neural processing, this work introduces physically intelligent capsule robots (PI Capbots) that enable homeostatic monitoring and targeted delivery within the GI tract, without relying on centralized electronic control. Through embodied stimuli-responsive memory and logic, PI Capbots effectively distill rich, detailed, and redundant physiological information into a small set of decoupled and event-triggered outputs suitable for operations in in vivo environments. In each PI Capbot, multistable metamaterials encode intraluminal pressure as mechanical memory, programmable hydrogels implement orthogonal sensing and logic operations, and helical fibers enable multimodal locomotion.

For the first time, we showcase the underlyingmechanism of flexoelectric soft robotic grippers that operate under open- and closed-circuitconditions. To understand its gripping mechanism, we first formulate a flexoelectric specialCosserat rod theory that incorporates intrinsic strains such as intrinsic flexural strain, intrinsictwist, etc. The governing differential equations for the intrinsically strained flexoelectric rodhave been derived by dimensional reduction. Henceforth, we establish the constitutive relations and identify correct effective strain measures through work conjugate. We then use the newly developed theory to model flexoelectric soft robotic grippers subjected to a constraint. A numerical approach has been proposed to evaluate the required gripping force for grasping an object using a constrained flexoelectric gripper. We also develop nonlinear closed-form solutions under open- and closed-circuit conditions that show an excellent agreement with our numerical solutions. We finally highlight the capabilities of flexoelectric grippers at different values of flexoelectric coefficients and identify the gripping and non-gripping zones. On the one hand, the electric fields generated in the flexoelectric gripper under open-circuit conditions provide optimized force-feedback control to grip and prevent excessive localized damage to the object. On the other hand, the voltages directly provide optimized force-feedback control under closed-circuit conditions to grip and to prevent localized damage.

Furthermore, kinematic, dynamic, and force analyses was conducted to calculate the specifications of the designed gripper, which was compared to four commercial grippers.

This fact further increases the confidence in the optimal development of the designed gripper. According to FEA results, the maximum stress acting on the components of the gripper was 15.78 MPa, 39.45% of the yield stress of Acrylonitrile Butadiene Styrene (ABS).

One of the main project task consists in developing PRIDE to conduct on orbit servicing activity with no docking. PRIDE would be provided with a robotic manipulator system (arm and gripper) able to transfer payloads, such as scientific payloads, from low Earth orbiting platforms to PRIDE payload bay. The platform is a part of a space tug designed to move small satellites and other payloads from Low Earth Orbits (LEO) to Geostationary orbit (GEO) and viceversa. A study on this robotic technology is here presented. This research is carried out by Politecnico di Torino and Thales Alenia Space Italy (Grasping Manipulator Design), and by Thales Alenia Space Italy and Amet (PRIDE Robotics System Design). The system configuration of the robotic manipulator is first described in terms of volumes and masses. The assumed housing payload bay requirements in terms of volume (&lt;100 l) and mass (&lt;50 kg) combined with the required overall arm dimensions (4 m length), as defined following the stated mission scenario, and mass of the payload (5–30 kg) force to developing an innovative robotic manipulator with the task-oriented end effector. It results in a 7 degree-of-freedom arm to ensure a high degree of dexterity and a dedicate end-effector designed to grasp the payload interface. The gripper concept here developed consists in a multi-finger hand able to lock both translational and rotational payload degrees of freedom through an innovative under actuation strategy to limit its mass and volume. While in the literature in usual actuation architectures, underactuated systems have been realized where the first (nearest) phalanx closure led afterwards to the closure of the second (distal) one using the loading of a torsional springs and mechanical linkages, this system presents a new underactuation strategy. In this case the distal phalanx closes before the nearest one, allowing to grasp the handle side and limiting the handle length and volume. This concept will allow the distal phalanx to move independently from the nearest one. A configuration study on the payload handle interface has also been performed. Moreover, trade-off studies, computer aided design models, multibody and structural analysis of the whole system are shown to prove its feasibility. Finally, the concept of system control architecture, organized in three main blocks is defined: the Control Overall System Block, the Control Arm Block and the Control Robotic Hand Block.","url":"https://doi.org/10.1115/imece2016-65429","authors":["Giancarlo Genta","Marco Dolci"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-02-11T23:30:34Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1115/imece2016-65429","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.20944/preprints202408.1704.v1","name":"Human Centered Sensor Technologies for Soft Robotic Gripper: A Comprehensive Review","source":"europepmc","abstract":"The importance of bio robotics has been increasing day by day.

In addition, the fabrication method of the pneumatic soft robotic gripper is introduced. The pneu-net actuator geometrical parameters are optimized such as the thickness of the chamber walls and the internal structure of the chambers resulting in significantly improved pressure handling capabilities. The simple pneu-net and the modified actuator are tested at two different pressure 55 and 110 kPa, to check the range of motion. A single actuator is calculated to lift a maximum of five kilograms, with several actuators included in the gripper the weight carrying capabilities reached ten kilograms. The geometry was optimized to maximize weight carrying capabilities by increasing the amount of pressure the actuator can withstand. A finite element analysis using ABAQUS software is carried out to evaluate the stresses acting upon the soft gripper.","url":"https://doi.org/10.1115/imece2022-95931","authors":["Ayman Abbas","Anwar Sahbel"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-02-08T21:14:58Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1115/imece2022-95931","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1115/imece2018-86274","name":"Brain-Computer Interface Application in Robotic Gripper Control","source":"crossref","abstract":"In robotics research, the electroencephalograph (EEG) based brain-computer interface (BCI) as a control input has been used in designing prosthesis, wheelchairs and virtual navigation.

The first subsystem acquires a signal from the brain through the Emotiv EPOC EEG headset, extracts features and translates them into an input to the control system. The second subsystem incorporates kinematics and feedback from sensors, to control the multiple degrees of freedom used in the gripping device depending on the action specified by the higher-level BCI control. The BCI is trained to filter and extract features relating to the different hand motions from the data sets. Machine learning is used in conjunction with data filtering, feature extraction, and feature classification techniques to create a more accurate and personalized BCI hand control system. The system analyzes the EEG data, compares with the EEG data patterns from previous attempts.

In the random bin-picking process, the wide variety of objects in terms of shape, weight, and surface require complex solutions for the objects to be reliably picked. The challenging part of robotic bin-picking is to determine object pick-points correctly. This paper presents a simulation model based on ADAMS/MATLAB cosimulation for robotic pick-point evaluation for a 2-F robotic gripper. It consists of a mechanical model constructed in ADAMS/View, MATLAB/Simulink force controller, several support functions, and the graphical user interface developed in MATLAB/App Designer. Its functionality can serve three different applications, such as: (1) determining the optimal pick-points of the object due to object complexity, (2) selecting the most appropriate robotic gripper, and (3) improving the existing configuration of the robotic gripper (finger width, depth, shape, stroke width, etc.). Additionally, based on this analysis, new variants of robotic grippers can be proposed. The simulation model has been verified on a selected object on a sample 2-F parallel robotic gripper, showing promising results, where up to 75% of pick-points were correctly determined in the initial testing phase.","url":"https://doi.org/10.3390/app13042599","authors":["Primož Bencak","Darko Hercog","Tone Lerher"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-02-20T02:29:08Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.3390/app13042599","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.21203/rs.3.rs-225922/v1","name":"Model-based Design and Simulation of a Soft Robotic Gripper for Fabric Material Handling","source":"europepmc","abstract":"Abstract Fabric and textile materials are widely used in many industrial applications, especially in automotive, aviation, and consumer goods. Currently, there is a lack of automatic solutions for rapid and effective fabric handling operations that can be expanded to various applications, causing economic loss, workplace safety issues, and process bottlenecks. As a bio-inspired novel technology, soft robotic grippers provide new opportunities for the automation of fabric handling tasks. In this research, an elastomer-based tendon-actuated soft gripper for fabric pick and place tasks is developed through a model-based design approach. Based on finite element analysis, the gripper design is simulated, modified, and validated. Multiple design variables and their impacts are studied. Detailed motion patterns of the underactuated structure are obtained. After the design is established, a prototype is fabricated trough additive manufacturing and overmolding processes to physically test the functionality of the gripper and further validate the simulation results.","url":"https://doi.org/10.21203/rs.3.rs-225922/v1","authors":["Bowen Wang","Ruth Jill Urbanic"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.21203/rs.3.rs-225922/v1","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.2139/ssrn.5269199","name":"Slip Detection in Robotic Gripper Using Stretchable, Soft Multi-Axial Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5269199","authors":["Jae-Won Choi","Md Jarir Hossain","Shahba Tasmiya Mouna"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-26T15:43:13Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.2139/ssrn.5269199","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1007/0-387-70988-6_7","name":"Multiple-Part-Type Production: Dual-Gripper Robots","source":"crossref","abstract":"","url":"https://doi.org/10.1007/0-387-70988-6_7","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-05-03T12:52:30Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1007/0-387-70988-6_7","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1115/1.859735.paper55","name":"Classification of Electromyogram Signal for Control of Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1115/1.859735.paper55","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-08-26T20:47:35Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1115/1.859735.paper55","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1002/rob.4620030309","name":"Dynamics of manipulation mechanisms with constrained gripper motion.

In this paper, we consider scheduling of operations in a bufferless dual-gripper robotic cell processing multiple part types. The processing constraints specify the cell to be a flowshop. The objective is to determine the robot move sequence and the sequence in which parts are to be processed so as to maximize the long-run average throughput rate for repetitive production of parts. We provide a framework to study the problem, and address the issues of problem complexity and solvability. Focusing on a particular class of robot move sequences, we identify all potentially optimal robot move sequences for the part-sequencing problem in a two-machine dual-gripper robot cell. In the case when the gripper switching time is sufficiently small, we specify the best robot move sequence in the class. We prove the problem of finding an optimal part sequence to be strongly NP-hard, even when the robot move sequence is specified. We provide a heuristic approach to solve the general two-machine problem and evaluate its performance on the set of randomly generated problem instances. We perform computations to estimate the productivity gain of using a dual-gripper robot in place of a single-gripper robot. Finally, we extend our results for the two-machine cell to solve an m-machine problem.","url":"https://doi.org/10.2139/ssrn.1126092","authors":["Chelliah Sriskandarajah","Inna Drobouchevitch","Suresh Sethi","Ramaswamy Chandrashekaran"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-12-28T12:41:00Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.2139/ssrn.1126092","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1088/2631-8695/ae0ddc/v3/review1","name":"Review for \"Data-Driven Trajectory Optimization in Robotic Fruit Harvesting via Deep Learning-Based Perception, Gripper Configuration, and Fruit Morphometrics\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/2631-8695/ae0ddc/v3/review1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-01T00:44:52Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1088/2631-8695/ae0ddc/v3/review1","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.56726/irjmets82822","name":"Fabrication of a Robotic Gripper  for Handling Fragile Objects","source":"crossref","abstract":"","url":"https://doi.org/10.56726/irjmets82822","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-23T07:40:46Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.56726/irjmets82822","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1007/0-387-70988-6_6","name":"Multiple-Part-Type Production: Single-Gripper Robots","source":"crossref","abstract":"","url":"https://doi.org/10.1007/0-387-70988-6_6","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-05-03T16:52:30Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1007/0-387-70988-6_6","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/lra.2024.3401138/mm1","name":"A Fractal Suction-Based Robotic Gripper for Versatile Grasping_supp1-3401138.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3401138/mm1","authors":["Jeffrey Lipton"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-05-16T13:34:43Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1109/lra.2024.3401138/mm1","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1177/1729881419866580","name":"Adjustable compliance soft gripper system","source":"crossref","abstract":"This article proposes a novel, innovative, soft gripper system developed for the manipulation of objects of unknown or unspecified shape and consistence.

The gripper geometry is obtained through topology optimization to maximize material efficiency and mechanical advantage. Finite-element analysis and experimental validation confirm that the 3D-printed structure (30 g) achieves substantial bidirectional displacement under a 5 N input force. Performance testing demonstrates stable grasping, with successful manipulation of cubic objects at inclination angles up to 40° and pyramidal objects up to 50°. The integration of the cartwheel hinge enables more pronounced bidirectional motion and increased rotational capability, with a hinge thickness of 0.3 mm allowing rotation exceeding 90°, thereby improving grasping adaptability. Additionally, the gripper employs a modular structural design that allows rapid scaling from a two-finger pinch to a four-finger wrap. This system provides a lightweight and versatile solution for complex robotic manipulation tasks without the need for hardware redesign.","url":"https://doi.org/10.1177/17298806261448682","authors":["Saksit Janjaroun","Teeranoot Chanthasopeephan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-05T12:54:33Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1177/17298806261448682","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1007/978-3-319-48375-7_28","name":"Functional Design of a Robotic Gripper for Adaptive Robotic Assembly","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-319-48375-7_28","authors":["F.

Closed‐form algorithms for checking force closure and for predicting jamming are developed. Three quality metrics are introduced to improve the quality of the planned grasps.

The second is a measure of the efficiency of the grasp in terms of the contact forces. The third is a measure of the dependence of force closure on friction. These quality metrics are not restricted to cylindrical fingers and can be applied to n finger grasps.

Part of this revolution is accomplishing tasks previously performed by humans with advanced robots, which would replace the entire human workforce in the future. In some industries the workers are required to complete different operations in hazardous or difficult environments. Operations like these could be replaced with the use of tele-operated systems that have the capability of grasping objects in their surroundings, thus abandoning the need for the physical presence of the human operator at the area while still allowing control. In this research our goal is to create an assisting system that would improve the grasping of a human operator using a tele-operated robotic gripper and arm, while advising the operator but not forcing a solution. For a given set of objects we computed the optimal grasp to be achieved by the gripper, based on two grasp quality measures of our choosing (namely power grasp and precision grasp). We then tested the performance of different human subjects who tried to grasp the different objects with the tele-operated system, while comparing their success to unassisted and assisted grasping. Our goal is to create an assisting algorithm that would compute optimal grasps and might be integrated into a complete, state-of-the-art tele-operated system.","url":"https://doi.org/10.3390/app11062640","authors":["Tomer Fine","Guy Zaidner","Amir Shapiro"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-03-16T12:01:02Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.3390/app11062640","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/icit48603.2022.10002833","name":"Robotic Manipulator with Active Sensing Gripper for Grabbing Shredded Food","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icit48603.2022.10002833","authors":["Shota Higuchi","Kenji Suzuki"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-01-05T19:09:43Z","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1109/icit48603.2022.10002833","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.5772/63973","name":"Leap Motion Device Used to Control a Real Anthropomorphic Gripper","source":"crossref","abstract":"This paper presents for the first time the use of the Leap Motion device to control an anthropomorphic gripper with five fingers. First, a description of the Leap Motion device is presented, highlighting its main functional characteristics, followed by testing of its use for capturing the movements of a human hand's fingers in different configurations. Next, the HandCommander soft module and the Interface Controller application are described. The HandCommander is a software module created to facilitate interaction between a human hand and the GraspIT virtual environment, and the Interface Controller application is required to send motion data to the virtual environment and to test the communication protocol. For the test, a prototype of an anthropomorphic gripper with five fingers was made, including a proper hardware system of command and control, which is briefly presented in this paper. Following the creation of the prototype, the command system performance test was conducted under real conditions, evaluating the recognition efficiency of the objects to be gripped and the efficiency of the command and control strategies for the gripping process.

This study presents the fabrication and application of a U-shaped robotic gripper (U-SRG) and experimentally verifies the control performance of a magnetic control system for two-dimensional (2D) rotation, translational motion, deformation, and microsphere grasping. The magnetic component of the U-SRG was fabricated by doping polydimethylsiloxane with neodymium-iron-boron (NdFeB) powder, followed by molding via post-treatment with Ecoflex-30 elastic silicone. The magnetic field generated by the electromagnetic coils of a magnetic control system can be conveniently, quickly, and precisely regulated using computers. Moreover, a uniform magnetic field could be precisely steered within a 2D plane, and the deformation magnitude of the U-SRG could be tuned by adjusting the intensity of the uniform magnetic field. The planar motion of the U-SRG was controlled by a synthetic magnetic field, and its speed was adjusted according to the magnitude of the magnetic field gradient. The magnitude and direction of the magnetic field required for each segment of the U-SRG path can be preset using computer software, enabling the U-SRG to precisely grasp and release the microspheres. To improve the micro-object grasping efficiency of the U-SRG, a crab-inspired gripper, denoted as U-SRGs, was developed by optimizing the design of the U-SRG. The bioinspired design does not directly replicate the external morphology of crab claws; instead, it draws inspiration from the functional differentiation of paired crab chelae, which can cooperate while exhibiting different grasping roles. This biological principle was translated into an asymmetric magnetic design strategy for the U-SRGs. By asymmetrically doping the left and right fingers of the U-SRGs with NdFeB powder, the gripper achieved differentiated clamping deformation under a uniform magnetic field. Owing to this capability, U-SRGs can realize size-based screening, manipulation, and targeted delivery of micro-objects.","url":"https://doi.org/10.1088/1748-3190/ae76a3","authors":["Liguo Dai","Aofei Yan","Yuting Zhou","Zheng Li","Lichao Liu","Zhigang Liu","Xiaowen Song","Huadong Zheng"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.443Z","doi":"10.1088/1748-3190/ae76a3","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.1038/s41378-026-01364-4","name":"Intelligent soft robotic gripper for non-destructive grasping and attribute recognition via multi-modal waveguide tactile sensors.","source":"pubmed","abstract":"The intelligent soft robotic gripper integrated with tactile sensors significantly enhances the robot's execution capabilities in complex tasks, resolving critical shortcomings of traditional mechanical grippers-namely, fragile item breakage from rigid impacts, irregular object slippage, and inefficiency due to recognition errors.

Ever since automation first took hold in society, optimizing these functions has been of high priority, and a multitude of approaches has been taken to enable cheaper, more reliable, and more versatile gripping. Attempts are ongoing to reduce grippers’ weight, energy consumption, and production and maintenance costs while simultaneously improving their reliability, the range of eligible objects, working loads, and environmental independence. While the upper bounds of precision and flexibility have been pushed to an impressive level, the corresponding solutions are often dependent on support systems (e.g., sophisticated sensors and complex actuation machinery), advanced control paradigms (e.g., artificial intelligence and machine learning), and typically require more maintenance owed to their complexity, also increasing their cost. These factors make them unsuited for more modest applications, where moderate to semi-high performance is desired, but simplicity is required. In this paper, we attempt to highlight the potential of the tarsal chain principle on the example of a prototype biomimetic gripping device called the TriTrap gripper, inspired by the eponymous tarsal chain of insects. Insects possess a rigid exoskeleton that receives mobility due to several joints and internally attaching muscles. The tarsus (foot) itself does not contain any major intrinsic muscles but is moved by an extrinsically pulled tendon. Just like its biological counterpart, the TriTrap gripping device utilizes strongly underactuated digits that perform their function using morphological encoding and passive conformation, resulting in a gripper that is versatile, robust, and low cost. Its gripping performance was tested on a variety of everyday objects, each of which represented different size, weight, and shape categories. The TriTrap gripper was able to securely hold most of the tested objects in place while they were lifted, rotated, and transported without further optimization. These results show that the insect tarsus selected approach is viable and warrants further development, particularly in the direction of interface optimization. As such, the main goal of the TriTrap gripper, which was to showcase the tarsal chain principle as a viable approach to gripping in general, was achieved.","url":"https://doi.org/10.3390/biomimetics9030142","authors":["Julian Winand","Thies H.

Furthermore, we explored the motion characteristics of the clamps during the snap-through and snap-back processes and divided the motion into two phases: delay and snap. Force and response time tests show that the proposed bistable gripper can achieve fast bending within milliseconds under a low pull force during the snap phase. Grasping experiments demonstrated that the proposed robotic gripper is adaptable for grasping objects of various shapes and weights. After grasping, the bistable gripper can release the target by pulling the actuating rod and automatically return to the open state. This study reveals the unique bending mechanism of thin sheets that can be exploited for fast, versatile, and adaptive grasping. The bistable gripper exhibits the potential to reduce energy consumption and simplify control when performing tasks in unstructured environments such as space and underwater.","url":"https://doi.org/10.1088/1748-3190/acaa7d","authors":["Xianyang Cai","Bin Tang"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2022","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1088/1748-3190/acaa7d","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1088/1748-3190/ac965a","name":"A novel design of a passive variable stiffness soft robotic gripper.","source":"europepmc","abstract":"","url":"https://doi.org/10.1088/1748-3190/ac965a","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2022","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1088/1748-3190/ac965a","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1089/soro.2021.0200","name":"A Passively Conforming Soft Robotic Gripper with Three-Dimensional Negative Bending Stiffness Fingers.","source":"europepmc","abstract":"Robot grippers that lack physical compliance have a difficult time dealing with uncertainty, such as fragile objects that may not have well-defined shapes. Existing soft robotic grippers require a large empty workspace for their actuated fingers to curl around the objects of interest, limiting their performance in clutter. This article presents a three-dimensional structure that exhibits negative stiffness in every bending direction used as fingers in a class of soft robotic grippers. Our approach exploits a compliant mechanism in a conical shape such that a transverse external contact force causes the fingers to bend toward the contact, enabling passive conformation for an adaptive grasp, even in clutter. We show analytically and experimentally that the proposed fingers have a negative bending response and that they conform to objects of various diameters. We demonstrate a soft robotic gripper with three self-conforming fingers performing the following: (1) fingertip grasping, (2) power grasping, and (3) semipassive grasping in clutter. Grasping experiments focus on picking fruits, which exemplify delicate objects with unmodeled shapes with significant variation. The experimental results reveal the ability of the self-conforming structure to smoothly envelope a broad range of objects and demonstrate a 100% grasp success rate in the experiments performed. The proposed passively conforming fingers enable picking of complex and unknown geometries without disturbing nearby objects in clutter and without the need for complex grasping algorithms. The proposed structures can be tailored to deform in desired ways, enabling a robust strategy for the engineering of physical compliance for adaptive soft structures.","url":"https://doi.org/10.1089/soro.2021.0200","authors":["Ashley H.

In this work, the authors propose a suction‐based soft robotic gripper where suction is created inside a self‐sealing, highly conformable and thin flat elastic membrane contacting a given part surface. Such soft gripper can self‐adapt the size of its effective suction area with respect to the applied load. The elastomeric membrane covering edge of the soft gripper can develop an air‐tight self‐sealing with parts even smaller than the gripper diameter. Such gripper shows 4 times higher adhesion than the one without the membrane on various textured surfaces. The two major advantages, underactuated self‐adaptability and enhanced suction performance, allow the membrane‐based suction mechanism to grip various three‐dimensional (3D) geometries and delicate parts, such as egg, lime, apple, and even hydrogels without noticeable damage, which can have not been gripped with the previous adhesive microstructures‐based and active suction‐based soft grippers. The structural and material simplicity of the proposed soft gripper design can have a broad use in diverse fields, such as digital manufacturing, robotic manipulation, transfer printing, and medical gripping.","url":"https://doi.org/10.1002/advs.202100641","authors":["Sukho Song","Dirk‐Michael Drotlef","Donghoon Son","Anastasia Koivikko","Metin Sitti"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1002/advs.202100641","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.3390/s22134851","name":"Modeling and Analysis of a Composite Structure-Based Soft Pneumatic Actuators for Soft-Robotic Gripper.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s22134851","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2022","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/s22134851","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.3389/frobt.2021.730227","name":"A 3D-Printable Robotic Gripper Based on Thick Panel Origami.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2021.730227","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3389/frobt.2021.730227","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1089/soro.2020.0200","name":"Pneumatically Controlled Reconfigurable Bistable Bionic Flower for Robotic Gripper.","source":"europepmc","abstract":"Beyond their colorful appearances and versatile geometries, flowers can self-shape-morph by adapting to environmental changes.

It is ideal to use one robotic gripper to handle as many food products as possible. In this study, a scooping-binding robotic gripper is proposed to achieve this goal. The gripper was constructed using a pneumatic parallel actuator and two identical scooping-binding mechanisms. The mechanism consists of a thin scooping plate and multiple rubber strings for binding. When grasping an object, the mechanisms actively makes contact with the environment for scooping, and the object weight is mainly supported by the scooping plate. The binding strings are responsible for stabilizing the grasping by wrapping around the object. Therefore, the gripper can perform high-speed pick-and-place operations. Contact analysis was conducted using a simple beam model and a finite element model that were experimentally validated. Tension property of the binding string was characterized and an analytical model was established to predict binding force based on object geometry and binding displacement. Finally, handling tests on 20 food items, including products with thin profiles and slippery surfaces, were performed. The scooping-binding gripper succeeded in handling all items with a takt time of approximately 4 s.

Thermoplastic polyurethane (TPU) filaments, with and without conductive fillers, are now commercially available. However, conventional FDM still has some limitations because of the marginal compatibility with soft materials. Material selection criteria for the available material options for FDM have not been established. In this study, an open-source soft robotic gripper design has been used to evaluate the FDM printing of TPU structures with integrated strain sensing elements in order to provide some guidelines for the material selection when an elastomer and a soft piezoresistive sensor are combined. Such soft grippers, with integrated strain sensing elements, were successfully printed using a multi-material FDM 3D printer. Characterization of the integrated piezoresistive sensor function, using dynamic tensile testing, revealed that the sensors exhibited good linearity up to 30% strain, which was sufficient for the deformation range of the selected gripper structure. Grippers produced using four different TPU materials were used to investigate the effect of the Shore hardness of the TPU on the piezoresistive sensor properties. The results indicated that the in situ printed strain sensing elements on the soft gripper were able to detect the deformation of the structure when the tentacles of the gripper were open or closed. The sensor signal could differentiate between the picking of small or big objects and when an obstacle prevented the tentacles from opening. Interestingly, the sensors embedded in the tentacles exhibited good reproducibility and linearity, and the sensitivity of the sensor response changed with the Shore hardness of the gripper. Correlation between TPU Shore hardness, used for the gripper body and sensitivity of the integrated in situ strain sensing elements, showed that material selection affects the sensor signal significantly.","url":"https://doi.org/10.3389/frobt.2021.615991","authors":["Antonia Georgopoulou","Bram Vanderborght","Frank Clemens"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3389/frobt.2021.615991","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1089/soro.2020.0139","name":"Inflatable Particle-Jammed Robotic Gripper Based on Integration of Positive Pressure and Partial Filling.","source":"europepmc","abstract":"","url":"https://doi.org/10.1089/soro.2020.0139","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2022","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1089/soro.2020.0139","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.3390/molecules26030522","name":"Actuating Shape Memory Polymer for Thermoresponsive Soft Robotic Gripper and Programmable Materials.","source":"europepmc","abstract":"For soft robotics and programmable metamaterials, novel approaches are required enabling the design of highly integrated thermoresponsive actuating systems.

Afterward, the PDA was brought to reaction with 4,4′-diphenylmethane diisocyanate and 1,4-butanediol. The resulting polyester urethane (PEU) was processed to the filament, and samples were additively manufactured by fused-filament fabrication. After thermomechanical treatment, the PEU reliably actuated under stress-free conditions by expanding on cooling and shrinking on heating with a maximum thermoreversible strain of 16.1%. Actuation stabilized at 12.2%, as verified in a measurement comprising 100 heating-cooling cycles. By adding an actuator element to a gripper system, a hen’s egg could be picked up, safely transported and deposited. Finally, one actuator element each was built into two types of unit cells for programmable materials, thus enabling the design of temperature-dependent behavior.

Fiber Bragg grating (FBG)-based sensors are very popular among various fiber optic sensors, but their stiff nature makes it challenging to be used in soft robotics. In this study, a soft robotic gripper with a sinusoidally embedded stretchable FBG-based fiber optic sensor is demonstrated. Unlike a straight FBG embedding configuration, this unique sinusoidal configuration prevents sensor dislocation, supports stretchability and improves sensitivity by seven times when compared to a straight configuration. Furthermore, the sinusoidally embedded FBG facilitates the detection of various movements and events occurring at the soft robotic gripper, such as (de)actuation, object holding and external perturbation.

Here, a monolithically 3D-printed, rapeseed-flower-inspired self-reconfigurable soft gripper (SRSG) is presented, which can rapidly reconfigure its finger arrangement within ∼130 ms and achieves precise, reversible switching between diagonal and parallel configurations. The SRSG can be readily incorporated with detachable petal modules to alter the grasping workspace. Leveraging these capabilities enables a range of functions: rotating bulbs of varying diameters, picking fruits, grasping cross-scale objects ranging from 0.07 to 270 mm (grasping range ratio of ∼3857 times), lifting payloads up to 5.6 kg (∼106 times its own weight), and adaptively enveloping numerous fine particles, multiple live aquatic organisms, and fragile underwater targets. The fully soft, electronics-free SRSG establishes a self-reconfigurable grasping paradigm for robust operation in unstructured environments, and opens up new directions for soft robotic end-effectors.","url":"https://doi.org/10.1002/advs.76403","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1002/advs.76403","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.20944/preprints202607.1480.v1","name":"Analysis of a Manual Process and Proposal of a Semi-Automated Cell for Unpackaging Chocolate Bars in a Food-Grade Process","source":"europepmc","abstract":"","url":"https://doi.org/10.20944/preprints202607.1480.v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.20944/preprints202607.1480.v1","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.3389/frobt.2026.1807613","name":"Dual-arm admittance control using conformal geometric algebra.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1807613","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3389/frobt.2026.1807613","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.21203/rs.3.rs-10104025/v1","name":"Real-Time 3D Motion Tracking and Precision-Engineered Modular Wood Grippers for KIGUMI-Inspired CNC Wooden Block Assembly","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-10104025/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.21203/rs.3.rs-10104025/v1","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1016/j.ohx.2026.e00806","name":"Fin-Ray soft gripper for object manipulation with multi-robot systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.ohx.2026.e00806","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1016/j.ohx.2026.e00806","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3389/frobt.2026.1747157","name":"Passive adaptive grippers: a mini-review.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1747157","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3389/frobt.2026.1747157","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1038/s41598-026-42227-2","name":"An integrated tomato harvesting framework using a hybrid soft-rigid gripper with semantic segmentation and keypoint detection.","source":"pubmed","abstract":"This paper presents an autonomous tomato-harvesting system built around a hybrid robotic gripper that combines six soft auxetic fingers with a rigid exoskeleton and a latex basket to achieve gentle, cage-like grasping.

For perception, an RGB-D camera and a Detectron2-based pipeline perform semantic segmentation of ripe/unripe tomatoes and keypoint localization of the pedicel and fruit center under occlusion and variable illumination. An analytical model derived using the principle of virtual work relates servo torque to grasp force, enabling design-level reasoning about actuation requirements.

To address this challenge, this study proposes a robotic multimodal tactile sensing approach inspired by human mechanoreception for frost-damage detection during grasping. A robotic gripper equipped with a 6&#xd7;6 pressure matrix sensor and a piezoelectric vibration sensor was used to capture complementary tactile cues during standardized fruit handling, enabling the perception of subtle mechanical changes associated with early frost injury. Using 240 Citrus reticulata 'Hong Mei Ren' fruits under controlled experimental conditions, a Transformer-based multimodal fusion network was developed to jointly model pressure and vibration sequences for binary classification of normal and frost-damaged fruits. Across repeated stratified random-split experiments, the proposed method achieved a mean classification accuracy of 93.1%. Comparative experiments showed that the fusion model outperformed representative sequence-learning baselines, and ablation analysis confirmed that pressure-vibration fusion was more effective than either single modality alone. Attention-based temporal attribution further revealed that the most informative cues were concentrated in the initial contact and early loading stages, indicating the importance of early transient mechanical responses for frost-damage discrimination. Overall, the proposed approach demonstrates the feasibility of grasp-based robotic frost-damage detection under controlled experimental conditions.","url":"https://doi.org/10.3390/foods15091597","authors":["Yu Y","Wu Z","An C","Lv X","Zhao Y","Xu H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/foods15091597","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1038/s44182-026-00085-0","name":"Fracture-based grasping: dynamic impact enables predictable robotic anchoring to freshwater ice.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s44182-026-00085-0","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1038/s44182-026-00085-0","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/diagnostics16071093","name":"Collaborative Robotic Systems for Pre-Analytical Processing of Biological Specimens in a Medical Laboratory.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/diagnostics16071093","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/diagnostics16071093","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1038/s41467-026-70313-6","name":"Liquid metal universal grippers for gentle, adaptable, multiscale manipulation.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-026-70313-6","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1038/s41467-026-70313-6","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.3390/s26103022","name":"FEM-Based Estimation-Correction with Minimal Indentation Set for Internal Cavity Classification and Geometry Estimation in Deformable Objects.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26103022","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/s26103022","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1016/j.mtbio.2026.103093","name":"Ecoflex-hydrogel bilayer soft robot for pH-controlled drug protection and delivery.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.mtbio.2026.103093","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1016/j.mtbio.2026.103093","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.20944/preprints202607.1467.v1","name":"Digital Twin-Based Design and Validation of a Collaborative Robotic Cell for Automated Chocolate-Bar Unwrapping","source":"europepmc","abstract":"","url":"https://doi.org/10.20944/preprints202607.1467.v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.20944/preprints202607.1467.v1","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.20944/preprints202607.1473.v1","name":"Digital-Twin-Driven Design and Financial Validation of a Collaborative Robotic Cell for Automated Chocolate-Bar Unwrapping in a Small-Scale Confectionery Plant","source":"europepmc","abstract":"","url":"https://doi.org/10.20944/preprints202607.1473.v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.20944/preprints202607.1473.v1","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1016/j.vgie.2026.02.008","name":"Robotic-assisted traction and closure during colorectal endoscopic submucosal dissection.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.vgie.2026.02.008","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1016/j.vgie.2026.02.008","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/biomimetics11050347","name":"Object Recognition-Based Grasping with a Soft Modular Gripper.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics11050347","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/biomimetics11050347","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1039/d6mh00763e","name":"Geometry-driven multimodal tactile sensors with high-fidelity perception enabled by strain-invariant oxidized liquid metal electrodes.","source":"pubmed","abstract":"Multi-axis tactile sensors that simultaneously resolve normal and shear forces are indispensable for dexterous robotic manipulation and human-robot interaction.

First of all, the selection of end effectors must follow the biological characteristics of fruits: rigid grippers are suitable for hard skinned and regular fruits; soft grippers can reduce the damage of fragile crops to a certain extent; suction cups are suitable for smooth, barrier free surfaces; the envelope type is suitable for soft and lossless picking scenes; the combined suction and grip design is more suitable for unstructured environments. Secondly, the separation mode should match the characteristics of the stem: motion separation (torsion/pull) is suitable for weak stems, while cutting is mainly used for hard stems. Unlike previous literature, this review provides a field deployability checklist (including dust/water proofing, cleanliness, maintenance, aging prevention, and aspiration prevention) to narrow the results of the laboratory and the real field environment. The three future directions of multimodal perception, variable stiffness driving and reinforcement learning are logically related to the analysis in this paper: multimodal perception optimizes the perception limit, variable stiffness solves the rigid-flexible trade-off, and reinforcement learning provides adaptive strategies for different crops. This framework can match the end effector design with the crop-specific field conditions.","url":"https://doi.org/10.3390/s26113382","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/s26113382","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1021/acssynbio.5c00733","name":"OSCAR: A Modular Open-Source Robotic Platform for Biological Laboratories.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acssynbio.5c00733","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.1021/acssynbio.5c00733","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/s26072222","name":"Optimized Haptic Feedback and Natural Prehension System for Robotics and Virtual Reality Applications.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26072222","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/s26072222","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/s26030960","name":"Fluid Pressure Sensing Strategy Suitable for Swallowing Soft Gripper.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26030960","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.3390/s26030960","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.21203/rs.3.rs-9428133/v1","name":"Fast Convex Model Predictive Trajectory Planning for Robot-Assisted Landings","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-9428133/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:27.444Z","doi":"10.21203/rs.3.rs-9428133/v1","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1038/s41467-026-70380-9","name":"A bionic robotic trunk with tensegrity-enabled elephant-comparable stiffness variability for assisted daily living.","source":"pubmed","abstract":"Elephant trunks can rapidly vary their stiffness over a broad range, seamlessly switching between soft states for dexterous operation and rigid states for load-bearing tasks. Despite extensive efforts to mimic this stiffness variability using various approaches, such as jamming structures and phase-change materials, existing bionic robots are limited to narrow tunable stiffness ranges and/or slow switching frequencies. In this work, we present a bionic robotic trunk with a cable-driven tensegrity skeleton, leveraging synergistic and antagonistic muscle-mimicking mechanisms to achieve dynamic stiffness regulation. Through coordinated contraction of motor-actuated cables (i.e., antagonistic action), the robotic trunk achieves a stiffness range of 23.94 to 542.47&#x2009;N/m and a switching frequency of 1.06&#x2009;Hz, matching the adaptability of elephant trunks. This rapid and large-scale stiffness variation enables dexterous navigation in unstructured environments and powerful manipulation of heavy objects. Incorporated into an electric wheelchair with the human-machine interface, the robotic trunk assists a post-stroke individual with daily activities, such as opening cabinet doors, retrieving milk from refrigerators, and watering flowers.

In land-constrained Singapore, vertical farming is expanding to improve resilience. However, this expansion has a bottleneck: many varieties of delicate leafy vegetables still rely on manual harvesting. The task is labor-intensive, and hard to scale. We address this need with a two-finger pinching gripper that has compliant, morphing fingertips. The fingertips collapse to enter narrow gaps between densely packed plants, expand to create soft contact surfaces, and reconfigure to accommodate different plant geometries. They also pinch to secure a firm grasp when needed. We validated the approach through bench tests and a trial at a local farm. The gripper consistently grasped multiple leafy-vegetable types and completed lettuce harvesting when used with a root trimmer.

The resulting residual pose errors often cause impact, side loading, jamming, and insertion failure. To address this issue, we propose a staged vision-force collaborative framework (SVFC) for precision insertion of metallic valve components. The key idea of SVFC is to treat metallic insertion as a sensing-reliability handover process: vision is used to compress the global pose error into a force-recoverable local neighborhood, while force feedback subsequently takes over for residual centering and contact regulation. The framework divides the process into three sequential phases: vision-guided coarse alignment, force-guided residual pose correction, and compliant insertion under variable-parameter admittance control. During residual correction, the joint held by the gripper is driven along a local Archimedean spiral trajectory within the vision-defined neighborhood, and centering is determined using a convergence criterion based on the root-mean-square values of lateral forces and torques. During insertion, virtual stiffness and damping are adjusted online according to contact state to suppress transient impact and mitigate jamming under different fit conditions. Experiments on representative clearance-fit and interference-fit tasks show that the proposed method improves insertion success rate, reduces insertion time, and lowers peak contact forces compared with baseline methods, indicating that explicit coordination between vision-dominant alignment and force-dominant contact regulation is beneficial for metallic insertion.","url":"https://pubmed.ncbi.nlm.nih.gov/42252340/","authors":["Wu T","Zhang D","Liu B","Wu H","Ren L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jun 7","addedAt":"2026-08-06T15:48:27.444Z"},{"id":"pmid:42229508","name":"A U-shaped robotic gripper with displacement and deformation controlled by programmable magnetic fields.","source":"pubmed","abstract":"Magnetic soft robots are widely employed in micromanipulation applications because of their inherent biocompatibility, untethered actuation capabilities, and controllability.

As a result of the proposed gripper design, the system incorporated a dual-layer mesh structure, compliant hinges, silicone padding, and hook-shaped retainers, all synchronized with robotic trajectory planning to minimize adhesion, fracture, and deformation during frying.

Furthermore, experimental results demonstrated that the optimal frying time differed depending on operation mode-8 s for single mode and 11&#x202f;s for dual mode-conditions that maximized puffing and brightness while avoiding overprocessing. These optimal times were identified through a comprehensive evaluation of post-frying quality attributes, including optical, moisture-related, dimensional, mechanical-acoustic, and chemical indices. Analysis of physicochemical quality metrics further revealed that the dual mode exhibited greater structural consistency and higher quality uniformity compared to the single mode, while most other quality traits showed no significant differences between modes.

While commercial haptic interfaces offer high performance, their prohibitive cost limits their widespread adoption in general-purpose robotics. Furthermore, many low-cost solutions suffer from limited transparency, where the operator constantly fights the friction of the actuator even during free motion. This article presents the design and development of an innovative, cost-effective master-slave robotic system aimed at democratizing efficient haptic feedback devices. The solution is intended for remote manipulation of objects with a maximum mass of 1 kg, while limiting the gripping force to 50 N, thus ensuring the integrity of objects being manipulated. The device includes a master haptic module in the form of a clamp that reproduces the thumb-index-middle finger gripping motion performed by the user. The system relies on a custom haptic interface measuring the angular position of the master gripper, which is transmitted in real time to the slave gripper, so as to adjust the position of the clamp accordingly, thus optimizing the grasping control loop. As soon as an object is detected, using a force sensor integrated into the slave gripper, the master motor renders a resistive force, preventing the user from closing the haptic module. The other part of the system is the slave mechanical gripper with three fingers, each with three phalanges based on human anatomy, allowing the clamp to mechanically conform to irregular object geometries with a single actuator. The last but not least innovative aspect lies in the implementation of a current sensor, which provides the haptic feedback.

The distal gripper features a bilayer architecture, comprising a functional MXene@RGO/elastomer composite layer and a passive substrate layer.

To address these challenges, we propose a robotic e-skin fabricated using direct-ink-writing technology that enables rapid customization and scalable production of multimodal sensors. The e-skin can detect pressure, temperature, and shear forces through a facile sensor design modification without additional complex fabrication steps. The pyramid-structured tactile sensor demonstrates high sensitivity of 670 kPa -1 in the 0-100 kPa range, maintain long-term stability over 3500 cycles, and exhibits minimal signal drift of less than 3% after 9 days of continuous testing. A 4 &#xd7; 9 flexible sensor array is developed for real-time pressure mapping on both flat and curved surfaces. Integration with a robotic gripper combined with a K-nearest neighbor classifier achieves a 97.7% accuracy in object recognition. Furthermore, by replacing the sensing layer with a temperature-responsive polymer or incorporating a protrusion-patterned shear layer, the e-skin can function as a dual-mode temperature-pressure sensor or a shear-force sensor.

Two AI agents were developed: a control agent that monitors the system performance and decides if tuning is needed, and an optimizer agent that updates PID gains using either a guided system prompt or a self-directed free approach within a safe parameter range. The LLM integration was implemented through Python programming and Flask-based communication between the AI agents and the hardware system. Experimental results show that both tuning approaches effectively reduced standard error metrics, such as IAE, ISE, MSE, and RMSE.

Perancangan lengan robot berjari sebelumnya dibahas dalam permasalahan flex sensor. Robot dibagi atas dua bagian, bagian pengendali pada lengan manusia (transmitter) dan lengan robot (reciever). Lengan robot berjari ini berbasis mikrokontroler dengan menggunakan ATMega 32A pada pengendali dan ATTiny 2313. Robot menggunakan media wireless yaitu KYL 1020U. Dibutuhkan keseimbangan perancangan antara aspek mekanik dan elektronik untuk menghasilkan kinerja lengan robot berjari yang maksimal. Artikel ini membahas lebar pulsa motor servo bahu, lengan, siku bawah dan siku atas. Sudut putar motor servo ketika diberi beban dan tidak beroperasi adalah 0° sampai dengan 160° dengan rata-rata lebar pulsa 1,2 dan 1,7. Pada saat diberi beban dan beroperasi, sudut putar servo dan rata-rata lebar pulsa tidak berubah. Ini menunjukkan bahwa servo yang digunakan pada lengan robot sangat stabil. Nilai arus yang mengalir pada lengan robot berjari akan naik sesaat dari 6,7 mA menjadi 7 mA ketika motor servo bergerak (berputar), namun nilai arus tersebut akan kembali ke nilai awal (6,7 mA) ketika motor servo berhenti bergerak (berputar).

However, such signals are often obscured by strong periodic interferences from motor pole-pair and shaft rotation order components. To address this issue, three key improvements are introduced within the cyclic blind deconvolution (CYCBD) framework: (1) a comb-notch filtering strategy based on rotation domain synchronous averaging (RDA) to suppress dominant periodic interferences; (2) an adaptive fault order estimation method using the autocorrelation of the squared envelope spectrum (SES) for robust localization of the true fault modulation order; and (3) an improved envelope harmonic product (IEHP), based on the geometric mean of harmonics, which optimizes the deconvolution filter length. These combined enhancements enable the proposed improved CYCBD (ICYCBD) method to accurately extract weak fault-induced cyclic impulses under complex interference conditions. Experimental validation on a test rig demonstrates the effectiveness of the approach in enhancing and extracting the fault-related features associated with the inner race defect.","url":"https://doi.org/10.3390/vibration8040059","authors":["Yubo Lyu","Yu Guo","Jiangbo Li","Haipeng Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-01T09:37:21Z","addedAt":"2026-08-06T15:48:51.383Z","doi":"10.3390/vibration8040059","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.2139/ssrn.5255264","name":"Evaluating Object Detection using DHT11 Sensor and Servo Motor Integration","source":"crossref","abstract":"Sensor and actuator integration in embedded systems has emerged as a critical component of automation and robotics.

However, the conventional cascaded PI control framework is inherently constrained by its fixed-parameter design, making it highly susceptible to parameter variations and unmodeled disturbances. While intelligent control strategies—such as model predictive control (MPC)—provide a robust, multi-objective alternative, their intensive stepwise computational demand often degrades transient response. Motivated by the stochastic dynamics of motor operation, we propose a novel physics-informed control paradigm. Specifically, we formulate the FOC-based motor control as an online stochastic optimization problem, wherein the objective function is updated iteratively using stochastic gradient estimates, and the resulting time-varying subproblems are solved efficiently by the MSALM algorithm. Our approach significantly outperforms conventional PI controllers in environmental adaptability and disturbance rejection. Experimental results demonstrate that the proposed method achieves comparable high-precision tracking performance while significantly reducing computational time per iteration, ensuring rapid dynamic response and strict enforcement of physical constraints.","url":"https://doi.org/10.20944/preprints202604.0111.v1","authors":["Xianqi Zhang","Zewei Wang","Dan Xue","Zikang Han"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:51.383Z","doi":"10.20944/preprints202604.0111.v1","updatedAt":"2026-08-31T06:34:44.263Z"},{"id":"doi:10.1038/s41598-024-71647-1","name":"Fuzzy inference system enabled neural network feedforward compensation for position leap control of DC servo motor.","source":"pubmed","abstract":"","url":"https://doi.org/10.1038/s41598-024-71647-1","authors":["Huang Z","Yan Y","Zhu Y","Shao J","Zhu J","Fang D"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","addedAt":"2026-08-06T15:48:51.383Z","doi":"10.1038/s41598-024-71647-1","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.3390/s24041265","name":"Real-Time Moving Object Tracking on Smartphone Using Cradle Head Servo Motor.","source":"pubmed","abstract":"The increasing demand for artificially intelligent smartphone cradles has prompted the need for real-time moving object detection. Real-time moving object tracking requires the development of algorithms for instant tracking analysis without delays. In particular, developing a system for smartphones should consider different operating systems and software development environments. Issues in current real-time moving object tracking systems arise when small and large objects coexist, causing the algorithm to prioritize larger objects or struggle with consistent tracking across varying scales. Fast object motion further complicates accurate tracking and leads to potential errors and misidentification. To address these issues, we propose a deep learning-based real-time moving object tracking system which provides an accuracy priority mode and a speed priority mode. The accuracy priority mode achieves a balance between the high accuracy and speed required in the smartphone environment. The speed priority mode optimizes the speed of inference to track fast-moving objects. The accuracy priority mode incorporates CSPNet with ResNet to maintain high accuracy, whereas the speed priority mode simplifies the complexity of the convolutional layer while maintaining accuracy. In our experiments, we evaluated both modes in terms of accuracy and speed.","url":"https://doi.org/10.3390/s24041265","authors":["Han N","Ryu SJ","Nam Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","addedAt":"2026-08-06T15:48:51.383Z","doi":"10.3390/s24041265","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.3390/mi14071356","name":"Development and Performance Evaluation of Integrated Hybrid Power Module for Three-Phase Servo Motor Applications.","source":"pubmed","abstract":"This study aims to develop a 30 kHz/12 kW silicon carbide (SiC)/Si integrated hybrid power module (iHPM) for variable frequency drive applications, particularly industrial servo motor control, and, additionally, to theoretically and experimentally assess its dynamic characteristics and efficiency during operation.

The MallARD DOFs are invested in reducing the DOFs of the proposed manipulator. The actuators for the proposed manipulator are installed in the base, above the water line. Wires are used to transmit the power to the manipulator's joints. The proposed wire-driven manipulator can work under high radiation, carry a large payload, and be easily isolated from water. The design of the manipulator is described in detail. The inverse kinematics closed-form solution has been derived analytically. A real-world version of the proposed wire-driven manipulator has been successfully manufactured and tested. The experimental setup is constructed utilizing the proposed manipulator. The experimental results display the feasibility of the proposed tendon-driven serial manipulator. They show that the RMS error between the desired and actual values in each joint is less than 2.1o .

The advancement of precision agriculture is impeded by three persistent bottlenecks in field robotics, namely, unreliable wireless communication within crop canopies, computational limitations for real-time edge artificial intelligence (AI), and high costs of system integration. To address these challenges, as a proof-of-concept feasibility study, this work presents the design and integrated laboratory-based verification of a novel, low-cost, AI-driven plant protection robot. Its core innovation lies in the holistic co-design of a custom CRC-16-protected communication protocol, an edge AI-based pest detection pipeline, and a precision spraying mechanism within a unified architecture. Laboratory-based verification demonstrated that (1) an optimized YOLOv11l model achieves a mean Average Precision (mAP@0.5) of 0.806 for pest detection, with an inference latency of 35.7 ms, on a Raspberry Pi 4B; (2) the custom protocol ensured a data fidelity of 99.91%, with a transmission latency of 12.3 ± 2.1 ms; and (3) the robotic platform achieved a path tracking accuracy of 1.8 ± 0.5 cm and an operational coverage efficiency of 98.7 m²/h, with a projected operational cost of approximately $1.95 per hectare under idealized laboratory conditions. These results confirm the technical feasibility of the integrated approach as a foundation for future field development. This work provides a scalable, cost-effective framework that couples robust perception, reliable communication, and precise actuation, thereby offering a practical proof-of-concept for smart farming

and environmental conditions, autonomous robotic fish have emerged as a promising solution with their biomimetic propulsion, agile motion, efficiency, and capacity for underwater inspection, monitoring, data collection, and exploration tasks in complex aquatic environments. Inspired by fish spines, rigid-link fish robots (RLFRs), a category of robotic fish, are widely utilized in robotics research and applications. Their rigid, actuated joints enable them to reproduce the undulatory locomotion and high maneuverability of biological fishes, while the modular nature of rigid links between joints makes them cost-effective and easy to assemble. This review examines and presents recent approaches and advancements in the field of structural design, as well as Reinforcement learning (RL)-enabled controls with sensors and actuators. Existing designs are classified by joint configuration, with key structural, material, fabrication, and propulsion considerations summarized. The review highlights the use of Q-learning, Deep Q-Network (DQN), and Deep Deterministic Policy Gradient (DDPG) algorithms for RLFR controllers, showing their impact on adaptability, motion control, and learning in dynamic hydrodynamic conditions. Technical challenges-including unstructured environments and complex fluid-body interactions-are discussed, along with future directions.

Understanding these mechanisms could deepen biological knowledge and assist in developing more agile robots. To address this issue, we hypothesized that decentralized interlimb coordination mechanism and trunk movement are essential for the emergence of an inside leading limb in a galloping turn. To test the hypothesis, we developed a quasi-quadruped robot with simplified wheeled hind limbs and variable trunk roll and yaw angles. For forelimb coordination, we implemented a simple decentralized control based on local load-dependent sensory feedback, utilizing trunk roll inclination and yaw bending as turning methods. Our experimental results confirmed that in addition to the decentralized control from previous studies which reproduces animal locomotion in a straight line, adjusting the trunk roll angle spontaneously generates a ground contact sequence similar to gallop turning in quadruped animals. Furthermore, roll inclination showed a greater influence than yaw bending on differentiating the leading and trailing limbs. This study suggests that physical interactions serve as a universal mechanism of locomotor control in both forward and turning movements of quadrupedal animals.","url":"https://doi.org/10.3389/fnbot.2025.1628368","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:48:51.383Z","doi":"10.3389/fnbot.2025.1628368","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.3390/s26061838","name":"Development

In this study, we developed and preliminarily evaluated a low-cost, lightweight, portable hip-knee exoskeleton prototype capable of generating controlled hip and knee joint motion for rehabilitation-oriented range-of-motion training. The prototype was constructed mainly of 3D-printed polylactic acid parts and powered by a pair of high-torque servo motors in the hip and knee joints. A Bluetooth-connected Android app was programmed to offer two modes: rehabilitation mode for independent joint control and a gait-inspired sinusoidal mode that generates coordinated hip and knee joint trajectories. The cost of the materials used to construct the prototype is estimated to be USD 155 with a weight of about 2.1 kg. Joint motion performance was assessed through time-angle measurements at three predefined speed settings. The hip joint (approximately 60&#xb0; movement) was achieved in 2.2, 1.6, and 1.1 s and the knee joint (approximately 140&#xb0; movement) was achieved in 3.0, 2.0, and 0.6 s for slow, medium and fast modes, respectively. The trial-to-trial variation in commanded servo position remained below &#xb1;1&#xb0; under the tested conditions. The results demonstrate the feasibility of generating repeatable commanded hip and knee joint motion under controlled laboratory conditions.

To address this cold-start problem, we present a pseudo-supervised machine learning framework evaluated on a custom five-channel dataset comprising 199 servo motor telemetry samples (current, voltage, temperature, humidity, and vibration). The methodology integrates hard structural partitioning (k-means) and soft posterior confidence estimation (Gaussian Mixture Models) to characterize operating modes without prior annotation. Concurrently, an Isolation Forest model quantifies anomaly intensity and establishes a dynamic quantile-based threshold. A critical innovation of this research is the deterministic risk mapping derived from engineering priors; it defines the \"high-risk\" (abnormal) state by inversely weighting the physical safety margins of the sensors. This mechanism strictly maps unsupervised clusters to binary pseudo-labels. These labels are subsequently used to supervise downstream discriminators (Random Forest and Support Vector Machine). The final online diagnostic outputs a score-level fusion of the classifier probability and the GMM posterior, gated by the anomaly threshold. Quantitative evaluation demonstrates that the Random Forest model achieved a perfect F1 score of 1.000, while the comparative SVM yielded an F1 score of 0.997, proving the framework to be a robust, interpretable, and highly accurate solution for cold-start industrial health monitoring.","url":"https://pubmed.ncbi.nlm.nih.gov/42507628/","authors":["Ming Z","Qin X","Ye Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 10","addedAt":"2026-08-06T15:48:51.383Z"},{"id":"pmid:42451499","name":"Feasibility and Operational Limits of a Minimum-Cost Indirect UAV Thermal Sensing Workflow Based on Smartphone-Displayed Infrared Video.","source":"pubmed","abstract":"Professional UAV thermal imaging systems are widely used for inspection, environmental monitoring, search and rescue, agriculture, and technical diagnostics. However, their cost limits their use in education, preliminary field screening, rapid prototyping, and low-resource applications. This study evaluates a minimum-cost indirect UAV thermal sensing workflow based on a DJI Mini 4K consumer drone, a lightweight Servo King9000 smartphone, and a UTi260M smartphone-connected infrared thermal camera. In the proposed configuration, the smartphone displayed and recorded the thermal stream, while the onboard RGB camera of the UAV recorded the smartphone-displayed infrared video during flight. The aim was not to develop a radiometric UAV thermal imaging platform, but to determine whether such a low-cost configuration can provide qualitative presence/absence indication of clear thermal hotspots and to identify its operational limits. The system was experimentally assessed under no-payload and payload conditions, daylight and nighttime illumination, and several low-altitude operating heights. Additional motor-region thermal observations were performed using a UTi260T handheld thermal camera under loaded and unloaded operating conditions. The complete UAV-payload configuration had a measured mass of approximately 340 g, corresponding to an effective added payload of 91 g and a payload-to-UAV mass ratio of 36.5%. Payload operation reduced near-ground flight endurance from approximately 25 min to 14 min 40 s. The maximum observed motor-region temperature increased from 24.9 &#xb0;C under unloaded operation to 42.0 &#xb0;C under loaded operation, while motor thermal asymmetry increased from 4.8 &#xb0;C to 7.6 &#xb0;C. Nighttime and low-glare operation improved the readability of the smartphone-displayed thermal stream, with the most practical usability observed at approximately 10-20 m. The results show that the proposed workflow is feasible only for short-range qualitative thermal screening and clear hotspot presence/absence indication. The UAV-recorded video should not be interpreted as direct thermal data, but as an RGB recording of a smartphone display showing thermal information. Therefore, the workflow is not suitable for quantitative temperature measurement, radiometric thermal mapping, or accurate thermal shape delineation. The main operational limits are payload mass, suspended-load oscillation, display readability, reduced endurance, motor-region thermal loading, sensitivity to payload alignment, and the absence of raw radiometric data. Direct UTi260M smartphone-recorded thermal frames were additionally used for pixel-size-assisted qualitative verification of practical reference thermal targets, including a human-sized target and a vehicle-sized target, at selected low-altitude operating heights.","url":"https://pubmed.ncbi.nlm.nih.gov/42451499/","authors":["Stoyanov Y","Tashev A","Salapateva S","Mitev P","Yankov D","Hristova G","Tihanov G"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 4","addedAt":"2026-08-06T15:48:51.383Z"},{"id":"pmid:42451254","name":"Time-Optimal Trajectory Planning Method for Servo PMSM Based on Short-Term Dynamic Feasible Region Constraint.","source":"pubmed","abstract":"Aiming at addressing the problem whereby the traditional time-optimal trajectory planning based on the steady-state torque-speed characteristic cannot fully exploit the short-term dynamic output performance of the servo permanent magnet synchronous motor (SPMSM), a time-optimal trajectory planning method for the SPMSM based on the short-term dynamic feasible region constraint is proposed to effectively improve the response speed. Firstly, the dynamic trapezoidal domain operation boundary is obtained by analyzing the motor working point variation curve and considering factors such as the working temperature and trajectory control, which constitutes the torque-speed value and the dynamic constraint mechanism of trajectory planning. Secondly, based on the energy consumption model, the average thermal power is used to represent the torque overload limit condition, and a dynamic constraint method based on the short-term dynamic torque-speed operation boundary is proposed. Then, in order to reduce the computational load in the online millisecond-level response, a time-optimal trajectory optimization algorithm based on sequential least squares is proposed to calibrate the positioning time of the time-optimal trajectory under different working temperatures and angles.

The proposed tricopter architecture comprises mechanically reconfigurable dihedral angles (0&#xb0;-30&#xb0;) on its three arms and a hybrid tail rotor system capable of both conventional servo-deflection yaw control and thrust-differential yaw generation. This dual-mode yaw technique significantly improves torque bandwidth and agility in degraded conditions. The tightly coupled, nonlinear six-degree-of-freedom (6-DOF) dynamics coming from dihedral reconfiguration and rotor interaction with DOB-ASMC are presented. A nonlinear disturbance observer (NDO) is introduced for the estimation of time-varying external disturbances, including wind gusts, motor asymmetry, and structural flexibility, feeding compensatory signals into an adaptive sliding mode control law whose switching gain self-tunes based on estimated disturbance magnitude. A proof of Lyapunov stability analysis with finite-time convergence is presented for a sliding surface and ultimate boundedness of tracking error.

Here, we present an open-source, home-cage-compatible system for automated REM sleep deprivation in mice that integrates physiological monitoring with real-time closed-loop motor control. Electroencephalography (EEG) and electromyography (EMG) signals are acquired using an Open Ephys acquisition board coupled to an Intan RHD-series headstage (Intan Technologies, USA). Real-time REM detection relies solely on EEG-derived spectral features, whereas offline brain-state annotation is performed using combined EEG and EMG recordings. The real-time classifier discriminates REM, wake, and non-rapid eye movement (NREM) states with accuracies of 88.6%, 80.4%, and 89.1%, respectively. Upon REM detection, the Open Ephys board outputs a Transistor-Transistor Logic (TTL) signal to a servo motor controller (Maxon ESCON 50/5), which drives a gently moving platform to selectively disrupt REM episodes. During a continuous 48&#xa0;h deprivation protocol, REM sleep was robustly suppressed. At 24&#xa0;h, the baseline-to-deprivation ratio for REM was approximately 15.9x, while wake and NREM ratios were approximately 0.66x and 1.46x, respectively.

However, the study of the characteristics and behavior of these objects on Earth is a challenge, as the simulation of their environmental conditions is difficult. We present in this paper an approach to enable the gravity simulation of SSSBs, such as comets or asteroids, in a drop tower facility on Earth, which is being addressed as part of the AKUS (\"Activity of Comets under Partial Gravity\") project.

A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of bilateral somites from the unsegmented tail tissue along their major axis. Earlier work discovered that segmentation is instructed by an oscillatory fibroblast growth factor (Fgf)/ERK signaling gradient sourced from the tailbud. Somite segmentation was recapitulated at will in the absence of the molecular oscillator, \"the segmentation clock\", via pulsatile drug inhibitions. Here, we present a live imaging setup for zebrafish embryos that incorporates a 3D-printed chamber and a programmed syringe pump for precise, automated, periodic drug delivery. The chamber secures the orientation of zebrafish embryos in agarose inserts and incorporates inflow and outflow ports to facilitate controlled drug perfusion. Servo motors controlled by an Arduino were integrated to automate valve switching, achieving fully automated exchange of two different fluids for alternating drug delivery and rinse cycles. Such periodic delivery of an inhibitor drug entrains the Fgf/ERK signaling gradient in the embryonic tail to oscillate in clock-deficient mutants, creating lab-reconstituted somites in otherwise defective embryos. Embryos expressing fluorescent markers can further be imaged at single-cell resolution during perturbations. Overall, this system provides a cost-effective, reproducible platform for investigating vertebrate development and interrogating cellular decision-making under controlled experimental conditions.

However, current curing practices are still dominated by manual operations, which are generally characterized by high labor intensity, low efficiency, high labor costs, and insufficient operational safety. These limitations hinder the large-scale, standardized, and efficient development of the tobacco curing process. To address these challenges, this study designed and developed a tobacco pole transfer and loading machine specifically for dense curing barn environments, based on the structural characteristics of dense curing barns and the technological requirements of tobacco pole loading. The proposed machine adopts a multi-stage lifting system combining a five-stage mast, servo motors, and ball screws, enabling precise vertical lifting within a range of 1.3~3.6 m. A reciprocating tobacco pole carrying mechanism, driven by staggered linear modules, allows adjustable pole inclination within a range of 0~32&#xb0;, effectively avoiding interference with curing barn walls. Finite element analysis of key components indicates that the strength of major load-bearing structures, including the powered chassis and lifting mast, meets safety requirements. The natural frequencies of mast stages 1 to 6 range from 63.92 to 354.00&#xa0;Hz, avoiding resonance during operation. In addition, the safety factor of the tobacco pole carrying blade is significantly higher than the allowable value, satisfying fatigue life design criteria. Field experiments conducted in tobacco-producing areas demonstrate that the loading success rate of the developed machine exceeds 90%, and operational efficiency is improved by approximately 3 to 5 times compared with traditional manual methods. The results confirm that the proposed tobacco pole transfer and loading machine can effectively accomplish pole transportation and hanging tasks in dense curing barns, substantially improving curing operation efficiency.","url":"https://pubmed.ncbi.nlm.nih.gov/42111742/","authors":["Guo T","Tang H","Li M","Liu C","Chen C","Wang L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:48:51.383Z"},{"id":"pmid:42111428","name":"ThongPaDisp: An open-source 3D-printed shuttlecock dispenser using a Grip-Gate-Push mechanism.","source":"pubmed","abstract":"This paper presents ThongPaDisp, a low-cost, open-source, 3D-printed shuttlecock dispenser developed to automate shuttlecock feeding.

Nevertheless, increasing the number of wefts with the existing selectors can impose challenges for the rapier in the efficient gripping of the weft. This study presents the design and development of a novel mechatronic weft selection system aimed at significantly enhancing the patterning capabilities of rapier looms. The proposed system features a circular arrangement of up to 20 weft yarn feeders and a single programmable selector module capable of handling the weft yarns. The selector integrates stepper motors, servo motors, solenoid valves, and an Arduino Mega-based control unit to execute user-defined weft patterns with high precision. The device was successfully operated at 9 picks per minute (PPM) across various yarn types, including polyester, viscose, and elastomeric yarns. A total of 11 different yarns were tested, each subjected to 5 trials using 20 feeders, resulting in the insertion of 1100 wefts. The system achieved a 100% selection and insertion success rate after the trials. The system also maintains a constant yarn-to-rapier angle, mitigating pick errors. The developed system offers a solution for expanding weft selection in rapier looms, enabling more intricate fabric designs and increased product versatility.

This paper proposes an adaptive disturbance rejection Zeta-backstepping control scheme with adjustable damping ratios to enhance system robustness and precision. An iron-core permanent magnet linear synchronous motor (PMLSM) was employed as the experimental platform for the development of a dynamic model that incorporates compensation for friction and cogging forces. To address model parameter uncertainties, an indirect parameter adaptation strategy based on a recursive least squares algorithm was introduced. It updates parameters based on the system state instead of output error, ensuring robust parameter convergence. An integral sliding mode observer (ISMO) was constructed to estimate and compensate for residual uncertainties, achieving finite-time state estimation. The proposed Zeta-backstepping controller enables adjustable damping ratios through parameterized control laws, offering flexibility in achieving desired dynamic performance. System stability and bounded tracking performance were validated via a second-order Lyapunov function analysis. Experimental results on a real PMLSM platform demonstrated that, while achieving adjustable damping ratio dynamic characteristics, there is a significant improvement in tracking accuracy and disturbance suppression.

The system aims to miniaturize the potential of 2-photon imaging in the metabolic and morphological characterization of cervical tissue at sub-micron resolution over large imaging depths into a flexible and clinically viable platform towards the early detection of cancers. Clinical implementation of such a probe system is challenging due to inherently low levels of autofluorescence, particularly when imaging deep in highly scattering tissues. For an efficient collection of fluorescence signals, our probe employs 12 0.5 NA collection fibers arranged around a miniaturized excitation objective. By bending and terminating a multitude of collection fibers at a specific angle, we increase collection area and directivity significantly. Positioning of these fibers allows the collection of fluorescence photons scattered away from their ballistic trajectory multiple times, which offers a system collection efficiency of 4%, which is 55% of what our bench-top microscope with 0.75 NA objective achieves. We demonstrate that the collection efficiency is largely maintained even at high scattering conditions and high imaging depths. Radial symmetry of arrangement maintains uniformity of collection efficiency across the whole FOV. Additionally, our probe can image at different tissue depths via axial actuation by a dc servo motor, allowing depth dependent tissue characterization. We designed our probe to perform imaging at 775 nm, targeting 2-photon autofluorescence from NAD(P)H and FAD molecules, which are often used in metabolic tissue characterization. An air core photonic bandgap fiber delivers laser pulses of 100 fs duration to the sample. A miniaturized objective designed with commercially available lenses of 3 mm diameter focuses the laser beam on tissue, attaining lateral and axial imaging resolutions of 0.66 &#xb5;m and 4.65 &#xb5;m, respectively. Characterization results verify that our probe achieves collection efficiency comparable to our optimized bench-top 2-photon imaging microscope, minimally affected by imaging depth and radial positioning.

A novel sliding mode surface (SMS) with predefined time convergence PDTC has been constructed, which ensures that the error converges to zero within the prescribed time. The system not only meets the expected performance standards but also has a uniformly bounded motor speed. The trajectory tracking error in SMS is proven to converge to zero within the predefined time. This predefined time stability of the closed-loop system has been demonstrated by using the Lyapunov stability criterion with PDTC. The convergence time (CT) can be arbitrarily set, and the upper bound of it is not affected by the initial value and control parameters of the system. A new updated version of extreme learning machine (ELM) is introduced to approximate the uncertain part of the system based on PDTC. The ELM is also provided with the hyperbolic tangent function to estimate the saturation constraint.

In response to these challenges, a novel biomimetic binocular cooperative perception system (BBCPS) was designed and its control was realized. Inspired by the gaze mechanism of human eyes, we designed a simple and flexible biomimetic binocular cooperative perception device (BBCPD).

Optical fiber mechanoreceptors embedded into a silicone layer prevail over their electronic counterparts due to the improved response and distributed detection ability. Nevertheless, current fiber Bragg grating and microfiber approaches demand intricate probe processing and rely on expensive spectral interrogators. Therefore, this paper introduces an agar-based artificial skin equipped with a concatenated multimode/singlemode/multimode optical fiber structure. Replacing elastomers with biodegradable hydrogel enables in-vivo operation as a biocompatible and disposable device, wherein its mechanical properties are adjustable according to the gel composition. Furthermore, speckle pattern analyses ensure high sensitivity and spatial discrimination by employing a visible laser and CCD camera. Experiments reveal force and bending resolutions of 0.04 N and 0.25 • , respectively, with a response time of 0.16 s. Evaluating complementary speckle images also conveys a spatial resolution of 1.12 mm through single-channel operation. Moreover, environmental surveillance tests yield a temperature resolution of 0.34 • C and highlight the sensor response to surrounding fluids. Such promising results anticipate forthcoming applications of the agar tactile skin in human-computer interaction and biomedical setups, establishing a biocompatible and biodegradable solution for in-vivo assessments.","url":"https://doi.org/10.36227/techrxiv.174284144.46307780/v1","authors":["Eric Fujiwara"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-03-24T14:37:37Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.36227/techrxiv.174284144.46307780/v1","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1299/jsmetokai.2018.67.707","name":"Relationship between the output of CMC tactile sensor and the shear force of its sensor element during tactile sensation","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmetokai.2018.67.707","authors":["Takahito IMAI","Takuya KAWAMURA","Katsutoshi OTSUBO","Hironao YAMADA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-09-24T22:27:45Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1299/jsmetokai.2018.67.707","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1016/b978-0-32-390445-2.00008-8","name":"GelTip tactile sensor for dexterous manipulation in clutter","source":"crossref","abstract":"","url":"https://doi.org/10.1016/b978-0-32-390445-2.00008-8","authors":["Daniel Fernandes Gomes","Shan Luo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-04-08T20:26:28Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1016/b978-0-32-390445-2.00008-8","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/vr.2007.352502","name":"Development of an Integrated Multi-Axis Tactile Sensor: Distributed Preprocessing for Tactile Recognitions","source":"crossref","abstract":"","url":"https://doi.org/10.1109/vr.2007.352502","authors":["Shunsuke Yoshida","Terukazu Mizota","Haruo Noma"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-04-25T15:13:12Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1109/vr.2007.352502","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.2139/ssrn.5463196","name":"A Bio-Inspired Tactile Sensor for Artificial Tactile Synapses","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5463196","authors":["Qijun Sun","Ling-Feng Liu","Zhe-Rui Zhao","Guowu Tang","Xin-Gu Tang","Ye Zhou"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-09T16:39:35Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.2139/ssrn.5463196","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/sensors47087.2021.9639483","name":"Nonlinear tactile estimation model using vibration information from tactile sensor mediated by mechanoreceptors’ perceptibility","source":"crossref","abstract":"","url":"https://doi.org/10.1109/sensors47087.2021.9639483","authors":["Momoko Sagara","Lisako Nobuyama","Kenjiro Takemura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-12-17T15:35:41Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1109/sensors47087.2021.9639483","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1299/jsmemecjo.2008.8.0_277","name":"539 A Fingertip Tactile Sensor Prototype with Epidermal Ridges for Multi-Purpose Somatosensation","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmemecjo.2008.8.0_277","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-08-06T22:47:08Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1299/jsmemecjo.2008.8.0_277","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.5772/4770","name":"Optical Three-Axis Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.5772/4770","authors":["M.

However, the available electronic and optical transducers rely on the intricate processing of multiple measurement channels to decode the bending magnitude and direction from whisker arrays. Therefore, this paper introduces a biocompatible, agar gel-made, vibrissa-like device with an optical fiber specklegram sensor embedded in its base. The hydrogel's biodegradability, softness, and tailorable viscoelastic properties support its feasibility for biomedical applications. Furthermore, speckle pattern analysis performs fiber quasi-distributed assessment by evaluating the correlation coefficient regarding reference images acquired by a camera. Experiments reveal practical resolutions of ∼0.7 mm and ∼13° for displacement magnitude and direction, respectively, allowing for interrogating two vibrissae connected to a single fiber. Moreover, dynamic tests highlight the optical signal changes due to shape and textural effects. Such a biocompatible whisker enhanced by a sensitive and straightforward interrogation approach motivates future developments toward biomedical probes for intra-body surveillance and soft robotics.","url":"https://doi.org/10.36227/techrxiv.172165658.82318281/v1","authors":["Eric Fujiwara"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-22T09:56:26Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.36227/techrxiv.172165658.82318281/v1","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/robot.1995.525384","name":"A three-axis optical tactile sensor (FEM contact analyses and sensing experiments using a large-sized tactile sensor)","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1995.525384","authors":["M.

Using the designed membrane type sensor (MTS), it is shown that the entire surface of the PVDF film can be employed as a means of detecting the force magnitude and its application point. This is accomplished by utilizing only three sensing elements. Unlike the array type tactile sensors, in which the regions between the neighboring sensing elements are not active, all the surface points of the sensor are practically active in this MTS. A geometric mapping process is introduced, thereby, the loci of the isocharge contours for the three sensing elements are determined by applying force on various points of the sensor surface. In order to form a criterion for the comparison between the experimental findings and the theoretical analysis data, and also to determine the magnitude of the stresses generated in the membrane, finite element modeling is used. The correlation between the theoretical predictions and experimental findings is proven to be reasonable. Potentially, the designed MTS can be incorporated into various medical probes for tactile imaging.","url":"https://doi.org/10.1108/02602280410545416","authors":["Javad Dargahi","Siamak Najarian"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2004-07-17T01:32:20Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1108/02602280410545416","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1021/acsami.0c12811.s001","name":"Bioinspired Color-Changeable Organogel Tactile Sensor with Excellent Overall Performance","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsami.0c12811.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-10-23T14:06:50Z","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.1021/acsami.0c12811.s001","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.3390/s21051572","name":"A Vibrissa-Inspired Highly Flexible Tactile Sensor: Scanning 3D Object Surfaces Providing Tactile Images","source":"europepmc","abstract":"Just as the sense of touch complements vision in various species, several robots could benefit from advanced tactile sensors, in particular when operating under poor visibility. A prominent tactile sense organ, frequently serving as a natural paragon for developing tactile sensors, is the vibrissae of, e.g., rats. Within this study, we present a vibrissa-inspired sensor concept for 3D object scanning and reconstruction to be exemplarily used in mobile robots. The setup consists of a highly flexible rod attached to a 3D force-torque transducer (measuring device). The scanning process is realized by translationally shifting the base of the rod relative to the object. Consequently, the rod sweeps over the object’s surface, undergoing large bending deflections. Then, the support reactions at the base of the rod are evaluated for contact localization. Presenting a method of theoretically generating these support reactions, we provide an important basis for future parameter studies. During scanning, lateral slip of the rod is not actively prevented, in contrast to literature. In this way, we demonstrate the suitability of the sensor for passively dragging it on a mobile robot. Experimental scanning sweeps using an artificial vibrissa (steel wire) of length 50 mm and a glass sphere as a test object with a diameter of 60 mm verify the theoretical results and serve as a proof of concept.","url":"https://doi.org/10.3390/s21051572","authors":["Lukas Merker","Joachim Steigenberger","Rafael Marangoni","Carsten Behn"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","addedAt":"2026-08-06T15:50:27.544Z","doi":"10.3390/s21051572","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1108/eb007546","name":"Using a tactile sensor to guide a robotic welding machine","source":"crossref","abstract":"Programming a multi‐axis robotic device to follow complex contours can be difficult and time consuming.

Proximity and tactile sensors are among the most important devices for collaborative robots to operate safely. In this paper, we propose a proximity and tactile sensor for a collaborative robot that combines multiple time‐of‐flight (ToF) sensors and a self‐capacitating proximity and tactile sensor. ToF sensors can detect the distance to an object and have a long measurement range. However, at close distances, their detection accuracy deteriorates, and blind spots may likely not be detected. Conversely, the self‐capacitance proximity and tactile sensor detect objects within the blind spots of ToF sensors and contact conditions because the sensor can detect an object before and after contact, being highly sensitive in the proximity range. In the proposed sensor, the electrodes of the self‐capacitance are enlarged, and multiple ToF sensors are used to expand the measurement range and reduce blind spots. A prototype sensor was seamlessly able to measure objects from approximately 400 mm to contact conditions. In addition, the robot arm with the prototype sensor could be controlled in real time using the measured data of the sensor. Therefore, we believe that the proposed sensor can be potentially used as a proximity and tactile sensor for collaborative robots. © 2023 Institute of Electrical Engineers of Japan.

By integrating living cells, muscles, or other biological components with engineered structures, biohybrid robots are designed to mimic natural processes and behaviors, offering the potential for significant advancements in soft robotics, medical devices, and autonomous systems. This paper explores the latest developments in biohybrid robotics, focusing on the design principles, challenges in integrating biological and synthetic components, and the potential applications in fields such as healthcare, environmental monitoring, and bioengineering. By leveraging the inherent advantages of biological tissues—such as self-healing, energy efficiency, and adaptive responsiveness—biohybrid robots could outperform conventional robotic systems in tasks that require flexibility, precision, and interaction with dynamic environments. This research also examines the ethical and technical challenges associated with the field, including the sustainability of biological materials and the long-term stability of these systems. The potential for biohybrid robotics to revolutionize industries by blending biological intelligence with synthetic durability underscores the significance of this rapidly evolving technology. Biohybrid robotics not only holds promise for creating more versatile and efficient machines but also represents a major step toward bridging the gap between biology and engineering. By harnessing the unique properties of biological systems, such as their ability to grow, repair, and adapt to changing environments, biohybrid robots can offer solutions to challenges that traditional robotics struggle to address. For example, in the medical field, these robots could assist in developing more effective prosthetics, bio-inspired implants, and even robotic systems that work inside the body to perform tasks with a level of precision and biocompatibility previously unattainable. This research delves into the potential for future advancements in areas such as environmental sustainability, where biohybrid robots could be used for tasks like pollution detection and waste management. Their biological components would enable them to interact with natural ecosystems in more seamless and non-disruptive ways. However, this integration of living tissues with technology also raises important ethical considerations regarding the use of biological materials and the extent to which we can manipulate living organisms for technological purposes.

However, these techniques may suffer from parameter drift, dependence on acceleration estimates and conservative requirements for system excitation. To overcome these limitations, composite adaptation laws can be used.

The effectiveness of the proposed approach is validated through experimental evaluation on a 3-DoF robotic leg.","url":"https://doi.org/10.20537/nd231212","authors":["S. Nedelchev","L. Kozlov","R.

The proposed compensator depends on the suspension of linear springs together with mechanical transmission mechanisms to achieve the constant application of force along the sliding span of the joint. The use of self-locking worm gears ensures the isolation of spring forces. A constant-force mechanism is proposed to generate counterbalance force along the motion span of the prismatic joint. The constant-force mechanism is coupled with a pin-slot mechanism to transform to adjust the spring tension to counterbalance the effect of rotation of the revolute joint. Two springs were used to counterbalance the gravity torque of the revolute joint. One of the springs has a moving pin-point that is passively adjusted in proportion with the moving mass of the prismatic joint. To derive the model of the compensator, a 2-DoF system which consists of a revolute and a prismatic joint is investigated. In contrast to previous work, the proposed compensator considers the combined motion of rotation and translation. The obtained results were tested in simulation based on the dynamic model of the derived system. The simulation shows the effectiveness of the proposed compensator as it significantly reduces the effort required by the actuators to support the manipulator against gravity. The derived compensator model provides the necessary constraints on the design parameters.","url":"https://doi.org/10.20537/nd221212","authors":["A. A. Demian","A. S.

The proposed control scheme is demonstrated through the modeling of a single rigid body with parameter uncertainties. The algorithm possesses notable strengths such as maximal compensation for parametric uncertainty, chattering reduction, and consideration of control input constraints. However, it is applicable for continuous systems and does not explicitly account for uncertainty in the control input.","url":"https://doi.org/10.20537/nd231205","authors":["C. A. Fam","S.

The paper considers the design of the compensator as an arrangement of elastic springs mounted on moving pivots. The moving pivots are responsible for adjusting the stiffness of the wrist-compensator coupling.

Predicting the swimming speed and efficiency of such devices in a reliable way is essential for their rational design, and to optimize their performance. The hydrodynamic simulations needed for this purpose are demanding and simplified models that neglect nonlocal hydrodynamic interactions (e.g., resistive force theory for slender, filament-like objects that are the typical propulsive apparatus for unicellular swimmers) are commonly used. We show through a detailed case study of a model robotic system consisting of a spherical head powered by a rotating helical flagellum that (a) the errors one makes in the prediction of swimming speed and efficiency by neglecting hydrodynamic interactions are never quite acceptable and (b) there are simple ways to correct the predictions of the simplified theories to make them more accurate. We also formulate optimal design problems for the length of the helical flagellum giving maximal energetic efficiency, maximal distance traveled per motor turn, or maximal distance traveled per unit of work expended, and exhibit optimal solutions.","url":"https://doi.org/10.1089/soro.2017.0099","authors":["Nicola Giuliani","Luca Heltai","Antonio DeSimone"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-05-15T11:25:52Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.1089/soro.2017.0099","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.22260/isarc1996/0055","name":"An Integrated Intelligent Planning Approach for Standardised Prefabricated Components","source":"crossref","abstract":"","url":"https://doi.org/10.22260/isarc1996/0055","authors":["Nashwan Dawood"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-10-31T21:15:16Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.22260/isarc1996/0055","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1016/0736-5845(84)90064-4","name":"4459663 Data processing machine and method of allocating inventory stock for generating work orders for producing manufactured components","source":"crossref","abstract":"","url":"https://doi.org/10.1016/0736-5845(84)90064-4","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-09-23T16:49:05Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.1016/0736-5845(84)90064-4","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.22260/isarc2011/0189","name":"Location Information Management of RFID-Equipped Building Components","source":"crossref","abstract":"","url":"https://doi.org/10.22260/isarc2011/0189","authors":["Ali Motamedi","Amin Hammad"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-10-14T14:33:49Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.22260/isarc2011/0189","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1007/s11370-026-00711-8","name":"Occlusion-resilient pose estimation of textureless components in cluttered environment and its implementation in robotic bin-picking","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s11370-026-00711-8","authors":["Nitin Desai","Debashis Sen","Sankha Deb"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-31T04:22:40Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.1007/s11370-026-00711-8","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1002/rob.21987","name":"Design and evaluation of a modular robotic plum harvesting system utilizing soft components","source":"crossref","abstract":"Abstract The human labor required for tree crop harvesting is a major cost component in fruit production and is increasing. To address this, many existing research works have sought to demonstrate commercially viable robotic harvesting for tree crops, though successful commercial products resulting from these have been few and far between. Systems developed for specific crops such as sweet peppers or apples have shown promise, but the vast majority of cultivar types remain unaddressed, and developing a specific system for each one is inefficient. In this study, an easily modifiable development platform for robotic fruit harvesting is presented, this can be used to test specific design choices on different fruit and growing conditions. The system is evaluated in a commercial plum orchard, with no crop modifications. Both a hard and soft gripper are trialed, along with three object detector approaches and two picking motions. Some existing techniques are found to be counterproductive for plums, while soft robotics and persistent target tracking significantly improve performance. The best harvest success rate of 42%, was observed when using the soft gripper with complex motion. This is lower than expected based on prior testing with apples and indicates the difficulty in moving to new fruit types. Unique challenges specific to the plum type and growing style are examined in the context of system module design choices.","url":"https://doi.org/10.1002/rob.21987","authors":["Jasper Brown","Salah Sukkarieh"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-09-25T19:59:45Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.1002/rob.21987","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1163/156855308x360596","name":"Positive Span of Force and Torque Components in Three-Dimensional Four-Finger Force-Closure Grasps","source":"crossref","abstract":"","url":"https://doi.org/10.1163/156855308x360596","authors":["Nattee Niparnan","Attawith Sudsang","Prabhas Chongstitvatana"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-11-06T20:06:55Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.1163/156855308x360596","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.11159/cdsr20.148","name":"Non-linear Parameter Identification for Humanoid Robot Components","source":"crossref","abstract":"","url":"https://doi.org/10.11159/cdsr20.148","authors":["Parastoo Dastangoo","Alex Ramirez-Serrano"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-11-06T19:52:30Z","addedAt":"2026-08-06T15:50:27.714Z","doi":"10.11159/cdsr20.148","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.53759/9852/jrs202402005","name":"Exploring Industrial Robot Control Systems: Components, Software and Applications","source":"crossref","abstract":"Automated manufacturing facilities are governed by resilient control systems that need little or negligible human interaction.

However, this advantage becomes a shortcoming in high-force applications where flexible components fold and fail under large loads. Various methods were sought to meet this challenge by providing a level of rigidity to soft components, but previously proposed solutions bring their own drawbacks including bulky systems, addition of superfluous weight, and restriction of actuator motion. Alternatively, this article presents Tubular Jamming, a new and effective means of stiffening that is adaptable to motion, lightweight, and can be implemented with minimal equipment. In this study, the mechanism of tubular jamming is expounded and is demonstrated through two exemplary soft structures: a tubular jammed beam (TJB) and a tubular jammed hinge (TJH). Both TJB and TJH are exhibited in areas of fabrication, characterization, and a few possible examples of implementation in soft robotic systems. In the TJB structure, tubular jamming is found to increase bending stiffness by nearly threefold at the maximum pressure and packing ratio tested, compared with a traditional soft pneumatic actuator (SPA) beam. The TJB is shown to require less supply pressure to achieve the same performance as a traditional SPA and is shown to perform better in maintaining the vertical position of a borne object. A triangular support configuration made from TJBs is demonstrated to be proficient in weight bearing, supporting a load of nearly 33 times its own weight. In the TJH structure, tubular jamming is shown to have a compound effect on torque output, as three jammed tubule hinges produce approximately four times the torque of a single tubule hinge. The TJH is exhibited in a wearable elbow flexion device. Tubular jamming opens new possibilities for soft components to achieve the stiffness needed to perform high-force tasks such as weight bearing and large-scale actuation while retaining the suppleness to enable a safe robot-to-environment interface.","url":"https://doi.org/10.1089/soro.2018.0084","authors":["Tiana Miller-Jackson","Yi Sun","Rainier Natividad","Chen Hua Yeow"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-06-03T16:37:58Z","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1089/soro.2018.0084","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1109/idaacs.2013.6663046","name":"Session: Special stream in intelligent robotics and components","source":"crossref","abstract":"","url":"https://doi.org/10.1109/idaacs.2013.6663046","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-11-27T21:53:59Z","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1109/idaacs.2013.6663046","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1109/icra.2012.6224804","name":"DNA as template for nanobonding and novel nanoelectronic components","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2012.6224804","authors":["Michael Weigel-Jech","Sergej Fatikow"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-07-09T17:23:24Z","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1109/icra.2012.6224804","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1109/iccas.2010.5669804","name":"Components and an effective IDE of Open software Platform for Robotics Services","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iccas.2010.5669804","authors":["Soohee Han","Mi-sook Kim","Hong Seong Park"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-09-14T21:44:53Z","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1109/iccas.2010.5669804","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1109/robot.1991.131824","name":"Design of components for programmable passive impedance","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1991.131824","authors":["K.F.

The CCD array image consists of four light spots produced by four light beams (planes) from laser diodes. These light beams (planes) form the edges (faces) of a pyramidal shape, with the 2-D CCD array forming its base and the origin of the laser sources forming its apex. The algorithm for the computation of the location and orientation is based on the inverse transformation of the final trapezoidal light spots position, related to the original square light spots position on the 2-D CCD array. This algorithm determines the relative location and orientation of a floating 2-D coordinate system (corresponding to the 2-D CCD array) against a fixed 3-D coordinate system (corresponding to the apex of the pyramidal shape). The modular design presented here enables easy customizing of this sensory system for a wide variety of applications.","url":"https://doi.org/10.4018/978-1-59904-002-8.ch109","authors":["M.

Here, we present a bio-inspired integrated pressure-sensing memory system that mimics these capabilities using crack-based sensors and electro-mechanical metamaterial memory components. The device architecture comprises an upper pressure-sensing layer with thin-film crack-based sensors and a lower bistable metamaterial memory layer, both fabricated using silicone rubber-platinum bilayer structures. The pressure sensor demonstrates exceptional performance with high sensitivity of 53.5 kPa -1 and outstanding reproducibility with less than 0.9% variation across multiple testing cycles. The memory component exhibits bistable behaviour with an on/off resistance ratio exceeding 10 11 , enabling reliable non-volatile information storage through mechanical state transitions. When applied pressure exceeds a predetermined threshold (approximately 2.6 mN), the memory component undergoes snap-through buckling, transitioning from a high-resistance \"off state\" to a low-resistance \"on state\" (&#x2248;110 &#x3a9;). Environmental durability tests demonstrate stable operation in various liquid media and temperatures up to 130 &#xb0;C.

Careful coordination across the patient care pathway remains central to optimizing outcomes. Concurrently, rapid advances in digital health, wearable technologies, smart implants, and intraoperative innovations are being explored across orthopedics, with emerging applications in shoulder arthroplasty. Objective This narrative review synthesizes current evidence on digital technologies relevant to shoulder arthroplasty, with particular attention to the strength and origin of the available data. Patients and methods A structured review of recent literature was performed, including primary studies in shoulder arthroplasty as well as relevant evidence extrapolated from hip and knee arthroplasty. Areas examined included CT-based 3D planning, navigation, patient-specific instrumentation, robotics, augmented/mixed reality, mobile health (mHealth) platforms, wearable devices, tele-rehabilitation, sensor-enabled implants, and artificial intelligence (AI). Results In shoulder arthroplasty, digital planning tools, navigation systems, and patient-specific instrumentation have demonstrated improvements in implant positioning accuracy in selected studies; however, evidence linking these technologies to superior long-term clinical outcomes remains limited. Robotic systems and augmented reality applications are in early investigational phases. Postoperative digital health tools, including tele-rehabilitation and wearable monitoring, have shown non-inferior functional outcomes compared with conventional care in hip and knee arthroplasty, with only preliminary and pilot data currently available in shoulder populations. Sensor-enabled implants and AI-based predictive models represent emerging areas of research, but external validation, workflow integration, and cost-effectiveness analyses remain insufficient. Conclusion Digital and smart health technologies in shoulder arthroplasty are evolving and largely investigational. While early findings and extrapolated evidence from other arthroplasty domains suggest potential benefits in planning accuracy, patient engagement, and outcome monitoring, robust shoulder-specific clinical validation is limited. Further prospective studies are required before widespread clinical adoption can be recommended. This narrative review synthesizes emerging evidence in this field, which is currently dominated by feasibility studies, technical reports, and early-phase clinical investigations, with limited high-level outcome data specific to shoulder arthroplasty.","url":"https://doi.org/10.2147/orr.s605861","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.2147/orr.s605861","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1038/s41598-026-56206-0","name":"Cyber-physical inspection systems for high-accuracy industrial operations: standards-aligned architecture and sensor-driven traceability.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-026-56206-0","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1038/s41598-026-56206-0","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/s26072239","name":"Emerging Integrating Approach to Sensors, Digital Signal Processing, Communication Systems, and Artificial Intelligence.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26072239","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/s26072239","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/biomimetics11060395","name":"Hybrid Decision-Making Management for Material Selection in the Design of Wearable Pressure-Sensing Orthoses in Neurorehabilitation.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics11060395","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/biomimetics11060395","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3389/frobt.2026.1825254","name":"A methodological framework and experimental protocol for proactive human-robot collaboration with multimodal intention prediction and adaptive control.","source":"europepmc","abstract":"Industry 5.0 requires collaborative robots that can anticipate operator needs to improve fluency and safety in assembly. However, many human-robot collaboration (HRC) systems still treat perception, intention inference, and control as separate components. This study presents a theoretical perception-cognition-action framework that explicitly couples multimodal intention prediction with proactive and adaptive control. Multimodal observations such as RGB-D vision, gaze, wrist force/torque, robot joint state, and previous robot action are encoded by a hybrid Convolutional Neural Network (CNN)- Long Short-Term Memory (LSTM)-Transformer to estimate (i) a probability distribution over future human intentions and (ii) a short-horizon motion trajectory, trained with a composite loss that jointly optimizes classification and regression with kinematic coherence. The predicted intention probability is embedded into an augmented Markov Decision Process state, enabling a Soft Actor-Critic agent to learn continuous policies with rewards designed for synergy, efficiency, safety, and fluency. The main contributions of this study are the formal probabilistic linkage from intention prediction to adaptive control, the definition of a multi-output cognitive objective, and the design of an implementation-ready experimental protocol for future empirical validation. Overall, the proposed methodological framework and experimental protocol provide a reproducible basis for future empirical validation of proactive human-robot collaboration in industrial assembly tasks.","url":"https://doi.org/10.3389/frobt.2026.1825254","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3389/frobt.2026.1825254","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/s26144597","name":"HCFNet: A SAM2-Based Hierarchical Cross-Branch Frequency-Aware Network for Industrial Surface Defect Segmentation.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26144597","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/s26144597","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/mi17070804","name":"Process and Mechanism of Cutting Polyamide Films with an Ultraviolet Picosecond Laser.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi17070804","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/mi17070804","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/s26092626","name":"Advanced Sensors for Intelligent Robotic Systems: Vision, Touch, and Dexterous Manipulation.","source":"europepmc","abstract":"Advanced sensing is rapidly reshaping intelligent robotic systems by enabling robots to perceive, reason, and interact with the physical world under real-world uncertainty [...].","url":"https://doi.org/10.3390/s26092626","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/s26092626","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1016/j.bbrc.2026.153390","name":"Micro-/nanorobots in nanomedicine - Guidance, imaging and the integration of AI and robotics.","source":"pubmed","abstract":"The integration of robotics and artificial intelligence (AI) into nanomedicine represents a significant advancement in developing targeted therapeutic and diagnostic platforms. This field focuses on engineering micro- and nanoscale agents, such as magnetic nanoparticles (MNPs), microbots, and nanobots, for tasks like targeted therapies, sensing, and manipulation at diseased sites. MNPs are typically composed of iron oxides and serve as foundational components due to their biocompatibility, tunable surface chemistry, and responsiveness to external magnetic fields. They are used in targeted drug delivery, magnetic hyperthermia for tumor ablation, and as contrast agents in magnetic resonance imaging (MRI) and magnetic particle imaging (MPI). Microbots and nanobots, which often incorporate MNPs for propulsion, can be actively guided using external magnetic fields to navigate complex biological environments, perform micromanipulation, and enable triggered drug release. The precise control of these magnetic agents relies on electromagnetic or permanent magnet-based guidance systems, which balance magnetic force strength, workspace volume, and clinical integration. Other classes like biohybrid microbots or DNA nanobots, utilize magnetic field independent mechanisms for molecular sensing and cargo delivery. AI and machine learning enhance these systems by optimizing material and bot design through in silico modeling, facilitating real-time navigation via medical imaging feedback, and enabling adaptive pathfinding. AI can also support swarm control and data analysis for diagnostic improvement.

We investigated the role of direct neural coupling by unilaterally transecting the posterior intermediate connective linking the mesothoracic and metathoracic ganglia in the cricket Gryllus bimaculatus . We analyzed kinematic changes and compared them with predictions from a purely neural phase oscillator network model featuring hierarchical asymmetric coupling. The experiments showed a clear dissociation: transection disrupted anti-phase coordination between the contralateral hind legs (from 188to 104, Cohen's) while frequency synchronization across all six legs persisted despite a substantial overall frequency reduction (from 4.8 Hz to 2.0 Hz). Amplitude and mean angle also changed in legs ipsilateral to the transection. The neural model reproduced the phase shift quantitatively (98.25, 5.5% error) but selectively departed from the biological data in three respects-the overall frequency reduction, the maintenance of synchronization among decoupled legs, and local amplitude and mean angle changes. Each departure points to a distinct role of embodied dynamics beyond neural connectivity alone. These results demonstrate a functional two-layer architecture: neural coupling establishes the baseline phase relationships (timing coordination), whereas descending excitatory drive, embodied dynamics, and sensory feedback cooperatively regulate movement frequency and amplitude (tempo and magnitude control). By experimentally isolating neural connectivity and comparing biological responses with a neural-only model, this study disentangles the distinct contributions of central circuits and physical dynamics. The findings provide biological evidence for a hybrid control strategy in which fixed neural patterning establishes coordination templates continuously adapted by mechanical interactions, offering bio-inspired design principles for resilient legged robots.","url":"https://doi.org/10.1088/1748-3190/ae822d","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1088/1748-3190/ae822d","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3389/fpls.2026.1853571","name":"PlantFormer: a precise plant disease segmentation network with interactive backbone and global-anisotropic context aggregation.","source":"europepmc","abstract":"Precise plant disease segmentation in real-world agricultural environments presents challenges that general-purpose models often fail to address, primarily due to the anisotropic spread of lesions, blurred biological boundaries, and severe background dominance. To overcome these bottlenecks, this paper proposes PlantFormer, an end-to-end network that effectively integrates and adapts advanced architectural components to address these domain-specific issues. Specifically, PlantFormer employs an InteractSwin Backbone with a Cross-Level Fusion (CLF) module to preserve early pathological details. To model highly directional disease propagation, a GlobalAnisotropic Context Aggregation (GACA) neck utilizing strip pooling is introduced. Furthermore, a Semantic-Guided Fusion (SGF) decoder acts as a feature \"boundary purifier\" to suppress field noise, while a decoupled boundary-aware loss function explicitly shifts the optimization focus from healthy leaf regions to subtle necrotic transition zones.

Biological control agents (BCAs), which utilize beneficial microorganisms, macroorganisms, semiochemical and botanicals to suppress pathogens, represent a cornerstone of sustainable agriculture but have been historically constrained by inconsistent field performance, high specificity, and slow action. Concurrently, Artificial Intelligence (AI) is emerging as a transformative force in agriculture, offering a powerful suite of tools for data analysis, prediction, and automation. The synergy of BCAs and AI creates advanced strategies where AI directly addresses the inherent limitations of biological control. It can foster the deployment of AI-driven predictive models for proactive pest outbreak forecasting, enabling timely and effective BCA application. Furthermore, it details the role of precision robotics and drones, guided by computer vision, in the targeted delivery of these agents. These components are synthesized into the concept of Integrated Pest Management (IPM) 5.0, where intelligent decision support systems orchestrate a holistic, data-driven approach to plant health. However, the realization of this vision is contingent on overcoming significant economic, regulatory, and adoption hurdles. High initial costs, complex and divergent regulatory countries in the EU and US, and socio-technical barriers to farmer adoption present formidable challenges.

In this review, wearability refers to body-mounted, skin-interfaced, textile-integrated, or otherwise human-attached triboelectric sensing platforms, whereas human-centric smart electronics refers to downstream electronic systems that remain functionally anchored to human-originated sensing, interpretation, feedback, or control. From this perspective, we review triboelectric wearable sensors from fundamentals to applications, covering working principles, material selection, device architectures, and fabrication strategies.

First, we employ rapid prototyping methods typically used for rigid structures, leveraging their precision to fabricate compliant components with reduced manufacturing errors. Second, our optimization framework minimizes the need for extensive prototyping, significantly reducing the iterative design process. The methodology enables the identification of stiffness parameters that are more practical and achievable within current manufacturing capabilities.

The method combines three components: local flow estimation, covariance-aware patch-boundary propagation with intermittent boundary fusion, and mission-level scheduling over multiple patches. Each patch is represented by a polygonal boundary, whose vertices are propagated through the estimated flow field while carrying per-vertex covariance, thereby quantifying uncertainty growth during advection. A flow-aware gain-scheduled linear quadratic regulator (LQR) was designed to shape the desired surge speed to take advantage of favorable currents. When the vehicle services a patch, boundary detections are fused to reduce the active patch uncertainty, and optional local map-covariance refinement is used to reduce subsequent uncertainty regrowth in the surrounding flow field. A boundedness analysis shows that if each patch is revisited within a prescribed maximum interval, then the corresponding patch uncertainty remains uniformly bounded; a companion feasibility condition relates the allowable revisit interval to vehicle speed, service time, and tour length over the patch set. To validate the result, a data replay simulation using HF-radar currents from the San Francisco Bay region was used to demonstrate the expected bounded sawtooth uncertainty behavior under feasible revisit conditions. In addition, our proposed duration-weighted predictive scheduler outperforms nearest-patch and round-robin baselines and, in spatially separated patch configurations, achieves lower mean patch uncertainty and lower control-effort proxy than a highest-J baseline. These results indicate that combining uncertainty-aware propagation with cost-aware scheduling is a viable strategy for persistent monitoring of evolving marine surface phenomena.","url":"https://doi.org/10.3389/frobt.2026.1842384","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3389/frobt.2026.1842384","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/biomimetics11060363","name":"A Modular Vision System for Practical Object Detection on Resource-Constrained Humanoid Robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics11060363","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/biomimetics11060363","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1002/rcs.70159","name":"A Tremor Suppression Method for the Master-Follower Surgical Robot Manipulator Based on Kalman Filter Algorithm.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/rcs.70159","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1002/rcs.70159","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1177/20552076261431899","name":"SHARA-WoZ: A multistakeholder framework to evaluate socially assistive robots thought Wizard of the Oz methods.","source":"europepmc","abstract":"","url":"https://doi.org/10.1177/20552076261431899","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1177/20552076261431899","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3390/polym18131650","name":"Binder-Centered Design of Sustainable Liquid Metal Composites for Adaptive Soft Energy Storage Systems: A Framework-Driven Perspective Review.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/polym18131650","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3390/polym18131650","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3389/frhs.2026.1810720","name":"Rehabilitation robotics in routine care: a minimum dataset and reporting framework for service delivery models.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frhs.2026.1810720","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3389/frhs.2026.1810720","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1016/j.dib.2025.112236","name":"Braiding machine for reinforcing silicone tubes with pineapple leaf fibers in soft robotics applications: Dataset on 3D design.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.dib.2025.112236","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1016/j.dib.2025.112236","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.3389/frobt.2025.1773450","name":"Editorial: Digital health applications of social robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1773450","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3389/frobt.2025.1773450","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.2196/72080","name":"Exploring Barriers and Enablers for the Intention to Use Assistive Robotics Among People With Spinal Cord Injury and Those Involved in Their Care: Qualitative Study.","source":"europepmc","abstract":"","url":"https://doi.org/10.2196/72080","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.2196/72080","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1002/med.70074","name":"AI-Driven Synthesis in Medicinal Chemistry: Integrating Large Language Models, Robotic Automation, and Sustainability Metrics to Accelerate Drug Discovery.","source":"europepmc","abstract":"Artificial intelligence (AI) is transforming synthetic chemistry from task-specific predictors into integrated platforms that unify retrosynthesis, reaction optimization, and closed-loop robotic automation.

Currently, no existing kinematic model is capable of describing the full range of locomotion exhibited by these animals. Addressing this challenge holds important implications for both the study of biomechanics of animals and the development of bioinspired robots. In this work, we propose a general kinematic model that integrates the curvature equation with a nonlinear oscillator. Through parameter adjustments, its morphology can transition between the motions of various animals. It is the most versatile kinematic model to date for describing multimodal locomotion of animals so far as we know. By translating the general kinematic model into a motion control algorithm and combining it with virtual simulation, we create a motion optimization framework that substantially simplifies the complexity of multimodal control for bionic robots with diverse actuation mechanisms, thereby enhancing their maneuverability. Using fish locomotion as an example, we validate the methodology on an untethered multijoint robotic fish, successfully enabling the robotic fish to perform cruising and various fast turn motions, thereby demonstrating its effectiveness in guiding motion control. This work is believed to have laid the foundation for the study of bionic motion and bioinspired robots.","url":"https://doi.org/10.34133/research.1275","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.34133/research.1275","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1002/ksa.70337","name":"Robotics in revision knee arthroplasty: Solution, support tool or new source of complexity?","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/ksa.70337","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1002/ksa.70337","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3389/frobt.2025.1662945","name":"Educational robotics as a strategy for social inclusion and pedagogical intervention in vulnerable youth communities.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1662945","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3389/frobt.2025.1662945","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.3389/frobt.2026.1727433","name":"Intent-driven LLM ensemble planning for flexible multi-robot manipulation.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1727433","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.3389/frobt.2026.1727433","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1002/advs.75985","name":"3D-Printed Magnetoelectronics for Interactive Appliances and Self-Aware 4D-Printed Mechatronics.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/advs.75985","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1002/advs.75985","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1016/j.cmpb.2026.109548","name":"Natural sit-to-stand control for biomimetic musculoskeletal robots with synergy-based deep reinforcement learning and bio-inspired reward shaping.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.cmpb.2026.109548","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1016/j.cmpb.2026.109548","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1063/5.0313395","name":"Design and experimental evaluation of a high-accuracy air temperature measurement instrument for meteorological applications.","source":"europepmc","abstract":"","url":"https://doi.org/10.1063/5.0313395","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1063/5.0313395","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"doi:10.1080/02688697.2026.2670643","name":"Immersive spatial computing in neurosurgery.","source":"europepmc","abstract":"","url":"https://doi.org/10.1080/02688697.2026.2670643","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z","doi":"10.1080/02688697.2026.2670643","updatedAt":"2026-08-31T06:34:10.196Z"},{"id":"pmid:42557482","name":"Surgeon-authorized natural-language and instrument-tracking shared control for robotic laparoscope holding: the EndoVISTA simulator and porcine feasibility study.","source":"pubmed","abstract":"Stable laparoscopic vision requires a camera that remains steady during fine manipulation yet can be repositioned promptly as the operative target changes.

Chinese expressions are grounded to bounded motion primitives, with speech retaining priority for fine adjustment, stop and override. In noise-controlled trials with ten Chinese-speaking participants, EndoVISTA achieved an 88.0% command-execution success rate at 85&#xa0;A-weighted decibels (dBA), compared with 76.0% for participant-specific KWS (mean paired difference, 12.0% points; 95% confidence interval [CI], 4.0 to 20.0), supporting robustness under the tested acoustic conditions.

In a single porcine workflow observation, 15 repeated or corrective commands were recorded with EndoVISTA and 32 with KWS.

Structural and morphological analyses of the MR reveal multiple oxide-rich phases, which improve both the dielectric properties and the surface microstructure of the MR/PDMS composite film.

The real-world use of the MR/PDMS TENG is further demonstrated by proof-of-concept applications: a glove-mounted tactile surface sensor with wireless signal transmission and a wearable triboelectric keypad. This work not only showcases advances in MR-based TENG performance but also marks the first demonstration of triboelectric applications using MR simulants as functional triboelectric material.

This paper presents the EPVS Challenge organized at MICCAI 2024, which aims to advance the development of automated algorithms for EPVS segmentation across multi-site data. We provided a diverse dataset comprising 100 training, 50 validation, and 50 testing scans collected from multiple international sites (UK, Singapore, and China) with varying MRI protocols and demographics. All annotations followed the STRIVE protocol to ensure standardized ground truth and covered the full brain parenchyma. Seven teams completed the full challenge, implementing various deep learning approaches primarily based on U-Net architectures with innovations in multi-modal processing, ensemble strategies, and transformer-based components. Performance was evaluated using dice similarity coefficient, absolute volume difference, recall, and precision metrics. The winning method employed MedNeXt architecture with a dual 2D/3D strategy for handling varying slice thicknesses. The top solutions showed relatively good performance on test data from seen datasets, but significant degradation of performance was observed on the previously unseen Shanghai cohort, highlighting cross-site generalization challenges due to domain shift.

A targeted narrative review of peer-reviewed literature on adhesion-related morbidity, adhesive small bowel obstruction (ASBO), laparoscopic adhesiolysis, and robotic surgery in patients with adhesions was performed. Current clinical data suggest that robotic surgery may reduce the conversion to open surgery due to adhesions in selected reoperative abdominal surgeries, particularly in expert hands and specific colorectal settings. However, outcomes beyond conversion, such as enterotomy rates, length of stay, and postoperative complications require further investigation. Successful robotic adhesiolysis relies on meticulous technical execution, including safe abdominal access, strategic port mapping, and appropriate instrument selection. Patient selection must carefully distinguish between elective reoperative surgery and emergency ASBO cases. Robotic adhesiolysis is a promising minimally invasive approach.

Such approaches require models that support interventional reasoning about therapy parameters (e.g., \"what if we increase robotic assistance or dose for this patient?\"), rather than providing purely associational findings such as biomarkers correlated with recovery. Leveraging recent developments in causal inference, this paper presents a structural causal model of robot-assisted therapy for the upper limb in the form of a directed acyclic graph. The graph encodes key constructs identified in the robot-assisted neurorehabilitation literature as nodes and represents their known or hypothesized causal influences as directed edges, reflecting current domain knowledge. We describe the components of the causal graph in detail and show how it can account for several observed phenomena in robot-assisted therapy, while also yielding testable predictions in the form of interventional effects. We then highlight important limitations of the proposed causal model, before presenting a conceptual example of how a fully specified causal graph could help answer questions about attainable outcomes and optimal therapy parameters for individual patients. The proposed concrete causal graph must be empirically investigated to test its validity and refine its causal structure through observational and experimental studies. We anticipate that this proposed causal graph will serve a catalytic role in advancing our mechanistic understanding of robot-assisted therapy, which may hold the key toward improving individual patient outcomes with robot-assisted therapy.","url":"https://pubmed.ncbi.nlm.nih.gov/42523754/","authors":["Balasubramanian S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42522738","name":"Regional Segregated Architecture Strategy for High-Efficiency Microwave Absorption of Polyimide Foam.","source":"pubmed","abstract":"Polyimide (PI) microwave absorption (MA) foam characterized by its superior electromagnetic protection performance and adjustable mechanical properties, is considered a quintessential structure-function integrated material.

Herein, leveraging the higher compressive strength of aramid honeycomb, a foam precursor solution with a more controllable foaming process is integrated into the aramid honeycomb framework to confine foam growth, thereby achieving excellent conformality between the PI foam and honeycomb. The confined growth of foam within the honeycomb cells mitigates the interfacial defects between cell walls and foam, synergistically coordinating the respective advantages of foam and honeycomb to achieve a mechanically reinforced composite foam structure. Experimental and simulation findings manifest that the optimized structural parameters of the wave-transparent phase (honeycomb), electromagnetic characteristics and topological configuration of the periodic foam units within the constructed regional segregated architecture positively influence MA performance. Ultimately, the optimized CNT/PI/Honeycomb composite foam is endowed with the effective absorption bandwidth (EAB), completely covering the entire X-band under flexible matching thicknesses (2.0-5.0&#xa0;mm), which highlights potential application in electromagnetic protection functional and load-bearing integrated structure.","url":"https://pubmed.ncbi.nlm.nih.gov/42522738/","authors":["Li N","Li ZY","Zhang F","Shi JF","Zong Z","Xu HK","Zhang YF","Chen YM","Deng ZH","Wang YY","Yan DX","Li ZM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 29","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42521833","name":"A genome-wide CRISPR screen in human prostate cancer cells reveals drivers of macrophage-mediated cell killing and positions AR as a tumor-intrinsic immunomodulator.","source":"pubmed","abstract":"Macrophages are the most abundant immune cells in the prostate tumor microenvironment and capable of killing tumor cells, but tumor intrinsic modulators of resistance to the innate immune system are unknown.

Growing recognition of inter-individual variability in knee phenotype, joint line orientation, ligament behaviour and patellofemoral anatomy has challenged the conventional 'one-size-fits-all' paradigm and promoted the development of more personalised strategies. This narrative review summarises the rationale for a more patient-specific approach to TKA and introduces the concept of functional knee positioning (FKPos) through a practical three-pillar framework integrating bone morphology, ligament behaviour and patellofemoral biomechanics. FKPos represents an evolution of functional alignment, moving beyond static coronal alignment towards an integrated, three-dimensional and patient-specific approach to implant positioning. FKPos is based on three interdependent domains, referred to as the three pillars: bone morphology, ligament behaviour and patellofemoral biomechanics. The bone pillar provides the anatomical foundation by restoring native joint line orientation and three-dimensional morphology within safe boundaries. The ligament pillar aims to achieve individualised, reproducible gap balance through implant positioning rather than systematic soft-tissue release. The patellofemoral pillar considers the anterior compartment as a dynamic and measurable component of knee function, with particular attention to trochlear anatomy, anterior offset and intraoperative tracking. CT-based robotic assistance enables accurate preoperative planning, intraoperative quantification of laxity, controlled adjustment of component position and dynamic assessment of patellofemoral tracking. These technological advances have improved the reproducibility of personalised TKA strategies and allow the three pillars to be assessed within a single operative workflow. Current evidence suggests that FKPos is feasible, safe and associated with satisfactory early clinical outcomes. However, clear superiority over other alignment strategies remains unproven, and long-term data are still required. The three-pillar concept provides a practical framework for patient-specific TKA by integrating bony anatomy, ligament balance and patellofemoral function. Its application should remain within defined safe zones and be interpreted as a functional positioning strategy rather than a universal target.","url":"https://pubmed.ncbi.nlm.nih.gov/42519811/","authors":["Fogacci A","Favroul C","Batailler C","Servien E","Lustig S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42519808","name":"Final intraoperative gaps commonly exceed resection-based reference gaps during sequential balancing in imageless robot-assisted total knee arthroplasty.","source":"pubmed","abstract":"The purposes of this study were to quantify final-minus-reference gap difference in the medial and lateral compartments in extension and flexion during passive, imageless robot-assisted total knee arthroplasty (RA-TKA) and to identify preoperative radiographic and initial intraoperative factors associated with greater final-minus-reference gap difference.","url":"https://pubmed.ncbi.nlm.nih.gov/42519808/","authors":["Morita Y","Shin J","El-Hassan M","Shichman I","Long WJ","Sculco PK"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42515758","name":"Pharmaceutical Compounding as a Pillar of Personalized Oncology: Current Applications, Emerging Technologies, and Future Perspectives.","source":"pubmed","abstract":"Personalized oncology is transforming cancer care by tailoring therapeutic strategies to the molecular and clinical characteristics of individual patients.

First, a Gated Adapter is introduced into the frozen SAM2 encoder, enabling efficient cross-domain transfer without massive parameter retraining, thereby effectively preserving the pre-trained visual priors. Secondly, a Laplacian-enhanced Auxiliary Branch is designed to explicitly amplify high-frequency components, compensating for the inherent perception limitations of the Transformer backbone and significantly awakening the model's sensitivity to subtle defects like micro-cracks. Finally, a Cross-branch Multi-scale Fusion Module is proposed to seamlessly align and integrate global semantic information with local structural details in a unified manner, resolving heterogeneous feature distribution conflicts. Extensive experiments on the MVTec AD and VisA datasets demonstrate that the proposed method consistently outperforms SAM2-based baselines in terms of mIoU and mDice.

This has led to substantial efforts aimed at improving the overall performance of additively manufactured components, particularly those produced by Material Extrusion (MEX). One of the main limitations of MEX-fabricated parts is the presence of air voids formed between deposited lines and layers, which reduce mechanical strength and structural uniformity. In this context, the present study investigates the influence of inter-layer ironing process parameters, an approach intended to modify near-surface morphology and improve the surface quality and dimensional accuracy of two commonly used materials, namely lightweight polylactic acid (PLA-LW) and standard. The experimental setup involved varying the ironing direction, nozzle diameter, and ironing spacing, while keeping all other manufacturing parameters constant. A complete 4 &#xd7; 3 &#xd7; 3 factorial experimental design was employed, considering three process parameters: ironing direction at four levels, nozzle diameter at three levels, and ironing spacing at three levels, resulting in 36 parameter combinations applied to each material separately. Performance evaluation included surface roughness (S a ), Shore D hardness, waviness (W a ), microscopic morphology analysis, and qualitative ultrasonic inspection used to observe internal void-related features, whereas the quantitative analysis focused on Sa, Wa, and hardness variations. The results were compared with those obtained for specimens produced using final-layer-only ironing and no ironing. Inter-layer ironing generally improved surface quality compared with non-ironed specimens, reducing Sa by up to 85.22% and increasing Shore D hardness by up to 10.40% for individual PLA-LW specimens manufactured using the 0.4 mm nozzle. The waviness response was strongly material-dependent; increasing the ironing spacing from 0.1 to 0.3 mm reduced Wa by 47.71% for PLA-LW and 13.39% for standard PLA, while the same spacing increase reduced Sa by 25.61% for PLA-LW but increased Sa by 10.87% for standard PLA. While PLA-LW specimens exhibited localized surface defects possibly associated with the compaction or collapse of near-surface voids, standard PLA specimens showed more pronounced waviness and material accumulation, highlighting the different responses of compact and foamed polymer structures to repeated thermo-mechanical ironing actions.","url":"https://pubmed.ncbi.nlm.nih.gov/42513796/","authors":["Tamașag I","Bejinariu C","Severin TL","Lupescu ȘC","Beniuga MC","Cerlincă DA","Beșliu-Băncescu I","Sachelarie AC","Vasilescu GD","Cimpoesu N"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 16","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42513724","name":"Enhancing Constitutive Description of 5A06 Aluminum Alloy During Warm Deformation Using Machine Learning-Assisted Johnson-Cook Model.","source":"pubmed","abstract":"To accurately characterize the warm deformation behavior and workability of the 5A06 aluminum alloy, this study presents an innovative workflow that develops and systematically validates machine learning-assisted Johnson-Cook (ML-JC) frameworks based on artificial neural network (ANN) surrogate models. Two predictive frameworks-the parallel-decoupled PD-ANN-JC and the multi-objective integrated MOI-ANN-JC-were constructed. Quantitatively, both developed ML-JC frameworks achieve significantly higher stress prediction accuracy and superior generalization capability compared with the conventional JC model. Specifically, on the testing set, the MOI-ANN-JC framework yields an average absolute relative error (AARE) of 1.424% and an R 2 of 0.997, outperforming the PD-ANN-JC framework (AARE of 3.246%, R 2 of 0.988). On the validation set, the MOI-ANN-JC framework also demonstrates exceptional generalization, with an AARE of 3.302% and an R 2 of 0.987. Scientifically, the superior performance of the MOI-ANN-JC framework stems from its ANN- mn&#x3b4; surrogate model, which simultaneously predicts the strain hardening exponent n , thermal softening exponent m , and relative error &#x3b4; directly from deformation parameters. This mutual coupling establishes an intrinsic correlation between m and n , successfully aligning with the physical reality wherein strain hardening and thermal softening are inherently linked during deformation. Qualitatively and practically, by integrating the MOI-ANN-JC framework into finite element (FE) simulation software, dynamic tracking and visualization of the thermal softening exponent m during warm deformation were achieved. Combined with FE simulations, Vickers hardness testing and EBSD observations, this study successfully establishes a direct qualitative spatial correspondence between low- m regions and macroscopic defects, which was further verified through the warm forging of a thin-walled dual-cavity component. Crucially, this approach for evaluating deformation stability bridges the gap caused by the inapplicability of conventional processing maps within this temperature regime, offering a robust and broadly applicable workflow for complex forming optimization.","url":"https://pubmed.ncbi.nlm.nih.gov/42513724/","authors":["Liu Z","Deng L","Long J","Gao C","Hao Y","Gong P","Tang X","Wang X"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 10","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42513071","name":"Binocular Vision-Based Image Extraction and Feature Analysis of Weld Beads in 316L Wire Arc Additive Manufacturing.","source":"pubmed","abstract":"To address the challenges of low image quality and difficult feature extraction of weld beads caused by the complex dynamics of the molten pool, intense arc light, and spatter interference during wire arc additive manufacturing (WAAM) of 316L stainless steel, this paper develops a binocular vision-based dynamic molten pool tracking system and conducts image processing and feature analysis. Two high-speed CMOS cameras are employed to capture images of the molten pool and weld bead. Camera calibration is performed to convert pixel coordinates to world coordinates. The denoising performance of five filtering methods, namely mean, Gaussian, median, maximum, and minimum filters, is systematically compared, and the minimum filter is selected for noise reduction. Adaptive threshold binarization, adapthisteq image enhancement, and morphological threshold segmentation are integrated to effectively separate the weld bead from the background.

This structured narrative review aimed to evaluate the contemporary role of IOUS in hepatic oncology surgery, with particular emphasis on contrast-enhanced intraoperative ultrasound (CE-IOUS), minimally invasive liver surgery, navigation-assisted hepatectomy, and emerging artificial intelligence-based technologies. Methods: A structured literature review was conducted using PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar databases. Peer-reviewed studies, international guidelines, consensus statements, systematic reviews, and technological reports addressing IOUS applications in liver surgery were analyzed. Particular focus was placed on studies evaluating lesion detection, intraoperative strategy modification, disappearing colorectal liver metastases, parenchymal-sparing hepatectomy, laparoscopic and robotic liver surgery, navigation systems, augmented reality integration, and AI-assisted imaging technologies. Results: Contemporary evidence demonstrates that IOUS continues to significantly influence intraoperative decision-making despite advances in magnetic resonance imaging and multidetector computed tomography. CE-IOUS improves the detection of occult hepatic lesions and residual disease after systemic chemotherapy, particularly in disappearing colorectal liver metastases. IOUS-guided anatomical and parenchymal-sparing resections contribute to the preservation of functional liver parenchyma while maintaining oncologic radicality.

The HHS significantly increased from preoperative (60.0&#xb1;14.1) points (range:40 to 74 points) to postoperative (95.9&#xb1;3.1) points (range:88 to 99 points) ( t =32.45, P &lt;0.01). The absolute value of postoperative leg length discrepancy was (6.5&#xb1;3.3) mm (range:0 to 18 mm), which was significantly lower than the preoperative value of (17.6&#xb1;11.2) mm (range:1 to 50 mm) ( t =9.152, P &lt;0.01).

In addition, we construct Momo, a large-scale LiDAR-based HAR dataset that focuses on long-range (2-30 m) outdoor scenarios where sparse point clouds and simultaneous human-sensor motion pose prominent challenges, complementing existing benchmarks by providing a dedicated evaluation platform for long-range outdoor HAR. Experimental results show that PePNet achieves consistent performance gains over existing methods on Momo.

During the last three decades, the conventional operation performed through median sternotomy with cardiopulmonary bypass has been complemented by off-pump, minimally invasive direct coronary artery bypass (MIDCAB), multivessel minimally invasive coronary surgery, robotic-assisted CABG, totally endoscopic CABG (TECAB) and hybrid coronary revascularisation (HCR). This narrative review summarises the evolution of CABG, compares conventional and minimally invasive approaches, and discusses current evidence, indications, limitations, implementation challenges, future directions and a practical decision algorithm for patient selection. A narrative literature review was conducted using PubMed/MEDLINE, Google Scholar, major cardiology and cardiothoracic guideline documents, and recent open-access reviews and meta-analyses published up to June 2026. Priority was given to contemporary guidelines, landmark trials, systematic reviews, meta-analyses and large observational series. Because this is a narrative review, no formal pooled analysis or risk-of-bias grading was performed. Conventional CABG provides reliable complete revascularisation and remains the preferred strategy for many patients with complex multivessel CAD. The survival value of the left internal mammary artery to left anterior descending artery graft underpins both conventional and minimally invasive strategies. MIDCAB is most established for isolated LAD disease and as the surgical component of HCR. Robotic-assisted CABG and TECAB reduce access trauma and may improve recovery, transfusion requirements and wound morbidity, but they require dedicated training, a specialised team and a high-volume programme to overcome the learning curve. HCR offers a biologically attractive compromise by combining durable LIMA-LAD bypass with PCI to non-LAD vessels, yet randomised evidence remains limited. The proposed algorithm translates these data into a clinically practical Heart Team pathway rather than a purely technique-centred comparison. The future of CABG is not a replacement of conventional surgery by a single minimally invasive method, but a personalised revascularisation strategy selected by a Heart Team. The most clinically relevant question is not whether one technique is universally superior, but which patient, coronary anatomy and institutional environment are best suited to conventional CABG, MIDCAB, robotic/TECAB or HCR.","url":"https://pubmed.ncbi.nlm.nih.gov/42503540/","authors":["Muafa HM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 27","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42496952","name":"Economic benefits of robotic-assisted ventral hernia repair in India: an analysis of health utility, productivity, and operational gains from the real-world ASPIRE INDIA study.","source":"pubmed","abstract":"This study estimated the economic benefits of robotic-assisted ventral hernia repair (RVHR) using individual patient data (IPD) from a prospective multicenter study, the ASPIRE INDIA.

The burden of ventral hernia continues to rise globally due to increasing rates of abdominal surgeries, aging populations, and the growing prevalence of risk factors such as obesity and metabolic disorders. Despite advances in surgical techniques, recurrence and postoperative complications remain important concerns, necessitating continuous refinement of management strategies. This narrative review synthesizes contemporary evidence on ventral hernia repair, focusing on mesh-based techniques, classification systems, patient optimization, and evolving surgical approaches. Mesh reinforcement remains the cornerstone of modern hernia repair, with strong evidence supporting the superiority of synthetic mesh over biologic mesh for recurrence outcomes, even in contaminated settings. Advances in mesh design, particularly the adoption of lightweight materials, have improved patient-reported outcomes by reducing chronic pain without compromising durability. Patient-related factors such as obesity significantly influence perioperative outcomes, highlighting the importance of individualized treatment strategies. The concept of loss of domain has emerged as a critical determinant of surgical complexity, with imaging-based volumetric assessment playing a key role in preoperative planning. Prehabilitation and multidisciplinary optimization have gained prominence as essential components of care. Evidence demonstrates that structured preoperative interventions, including exercise, nutritional support, and risk factor modification, reduce complications and improve recovery. Adjunct techniques such as botulinum toxin injection and progressive pneumoperitoneum further enhance outcomes in complex hernia repair by facilitating tension-free closure. Minimally invasive approaches, including laparoscopic and robotic techniques, have transformed ventral hernia surgery. Laparoscopic repair is associated with reduced wound complications and shorter hospital stays compared to open repair while maintaining similar recurrence rates. Robotic surgery offers additional technical advantages and improved short-term outcomes, although concerns regarding operative time and cost remain. Advanced techniques such as enhanced-view totally extraperitoneal repair and transversus abdominis release have expanded the surgical armamentarium for complex cases. Perioperative strategies continue to evolve, with emerging evidence questioning the routine use of surgical drains. Overall, ventral hernia repair has transitioned toward a patient-centered, evidence-based approach that integrates surgical innovation with perioperative optimization. Future research should focus on long-term outcomes, cost-effectiveness, and personalized treatment strategies to further improve patient care.","url":"https://pubmed.ncbi.nlm.nih.gov/42491431/","authors":["Kumar A N","Eswar CM","Yatheendranathan GD","Gopi C S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jun","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42487631","name":"Engineering Mesoporous Composite Nanospheres With Metal Core and Metal Oxide Shell for Plasmonic Promoted Gas Sensing.","source":"pubmed","abstract":"Nanoengineering of core-shell nanostructures integrating plasmonic metal cores and mesoporous semiconducting metal oxide (SMO) shells hold significant promise across catalysis, chemical sensing, diagnosis, micro-nano robots, and smart optics.

The as-fabricated sensors exhibit 6-fold enhancement of sensitivity toward low concentration NO 2 at room temperature under low-power green light illumination.

The benefits and limitations of the current techniques used; and 3. Future directions and their application to clinical practice. Traditional two-dimensional (2D) templating, although widely used, has limited accuracy due to magnification errors and variability in patient positioning. Three-dimensional computed tomography (3D-CT) preoperative planning allows for a more precise estimation of CoR. Integration with robotic systems enables intraoperative execution of the plan but comes with high costs and a steep learning curve. Patient-specific instrumentation (PSI) provides a cost-effective alternative. Meanwhile, surgeon experience and intraoperative judgement remain crucial, particularly in patients with abnormal anatomy or deformities. Restoration of CoR within approximately 5 mm of the planned medial and superior position has been associated with improved biomechanical performance and implant longevity. While 2D templating can achieve this in most routine cases, 3D planning, robotic-assisted surgery, and PSI allow for more accurate placement.

In exploratory adjusted analyses, the ambulatory pathway remained associated with lower rescue analgesia (adjusted OR 0.19, 95% CI 0.07-0.54), lower 24-hour moderate-to-severe pain (adjusted OR 0.39, 95% CI 0.20-0.78), and lower time-weighted mean NRS from PACU through 48 h (adjusted beta&#x2009;-&#x2009;1.77, 95% CI -2.46 to -1.07). Among the 84 patients in the ambulatory group, 78 (92.9%) were discharged successfully as planned; no unplanned readmission or reoperation occurred within 30 days. In selected patients undergoing RAPN, a short-stay ambulatory pathway centered on bundled multimodal analgesia and extended nursing follow-up was associated with lower pain scores, reduced rescue analgesic use, earlier recovery, and acceptable short-term safety. These findings support feasibility in carefully selected patients but do not establish superiority; prospective multicenter validation and cost-effectiveness analyses are needed.","url":"https://pubmed.ncbi.nlm.nih.gov/42477149/","authors":["Jiao L","Liu X","Tai Y","Shang J","Yao X"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 21","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42476041","name":"Magnetic three-dimensional dynamic tracking of total knee arthroplasty can detect rotational movements within one degree accuracy in most configurations: new principles for medical imaging.","source":"pubmed","abstract":"The laboratory-based study aimed to evaluate the utility and accuracy of a device in tracking the rotation of total knee arthroplasty (TKA) implants.","url":"https://pubmed.ncbi.nlm.nih.gov/42476041/","authors":["Naudi S","May O","Fouilleron N","ELSAN Working Group","Kheddar A","Dutrieux S","Mehdi N"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 20","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42474881","name":"Image-based navigation-assisted total hip arthroplasty in patients with morbid obesity: a matched cohort study in the United States.","source":"pubmed","abstract":"Image-based navigation-assisted total hip arthroplasty (THA) has been increasingly adopted to improve component positioning and reduce complications; however, its clinical benefit in patients who have morbid obesity remains unclear.

After matching, 5,835 patients who had morbid obesity undergoing THA were analyzed (1,473 navigation-assisted; 4,362 manual) with comparable baseline demographics and comorbidities. Outcomes included surgical complications (prosthetic joint infection [PJI], surgical site infection, dislocation, periprosthetic fracture, mechanical loosening, limb length discrepancy [LLD]), thromboembolic events (pulmonary embolism, deep vein thrombosis [DVT]), same-day blood transfusions, and revision surgeries (septic and aseptic) assessed at multiple postoperative timepoints including 30-days, 90-days, one-year, and two-year timepoints.

This study aimed to systematically review and meta-analyze how ra-THA compares to m-THA regarding component alignment precision, Lewinnek safe zone outliers, and early post-surgical dislocation frequencies. We searched PubMed, Embase, and the Cochrane Library for randomized controlled trials and high-quality observational cohorts comparing ra-THA with m-THA.

Data aggregation utilized fixed-effects or random-effects architectures based on baseline heterogeneity thresholds. Merging data from 15 studies (2,485 procedures) showed that ra-THA significantly reduced mean deviation from planned inclination and anteversion angles compared to manual controls (p&#x2009;&lt;&#x2009;0.05).

In this secondary analysis of a previously published cohort of 312 patients who underwent robot-assisted PVP for single-level OVCFs under local anesthesia (2023-2024), we developed and internally validated a predictive model for clinically unacceptable puncture (Gertzbein Grade C-E).

We analyzed 68 consecutive primary functionally aligned robotic TKAs performed by a single surgeon using a CT-based robotic-arm platform. Preoperative variables included hip-knee-ankle angle (HKA), flexion deformity, and independent medial and lateral gaps in extension and at 90&#xb0; flexion. A 10-case formative series informed concept generation; the finalized hierarchy was then applied to all cases using preoperative variables only. Four phenotypes were derived: bone-driven, ligament-driven, flexion-dominant, and mixed/complex (defined as the co-occurrence of two or more severe deformity drivers). Internal coherence was assessed through release escalation, corrected-state behavior, plan-to-final HKA fidelity, and mechanical and functional-alignment balance. Inter-observer reliability was tested by having five independent surgeons classify all cases blinded, with agreement quantified by Fleiss' and Cohen's kappa. All knees were classified: bone-driven, 40/68 (58.8%); ligament-driven, 6/68 (8.8%); flexion-dominant, 10/68 (14.7%); and mixed/complex, 12/68 (17.6%). Release escalation occurred in 1/68 (1.5%), with no posterior capsulotomy. Overall, 58/63 (92.1%) finished within &#xb1;&#x2009;2&#xb0; of planned HKA; strict mechanical balance was achieved in 58/62 (93.5%) and functional-alignment balance in 61/62 (98.4%). Flexion-dominant knees showed lower coronal fidelity but complete final balance, suggesting a coronal-sagittal trade-off during functional planning. Inter-observer agreement among the five surgeons was almost perfect (Fleiss' kappa 0.88, 95% CI 0.81-0.93; 92.4% overall agreement). Preoperative HKA, sagittal deformity, and medial-lateral gap asymmetry revealed recurring patterns organized into a four-phenotype driver framework.

This paper presents a real-time, accelerometer-in-the-loop vibration suppression framework that reduces these components online while maintaining tracking performance within the bounds observed in our experiments and operating within predefined safety limits. A tri-axial accelerometer mounted on the reducer housing provides high-bandwidth vibration measurements from which order-synchronous, band-limited metrics are computed in streaming form. These metrics define both the optimization objective and vibration exposure constraints. The control architecture retains the vendor servo loops and adds a vibration-targeted layer combining a low-dimensional anti-resonance parameterization (adaptive notch shaping and narrowband feedforward cancellation aligned with the estimated mesh-order family) with a safety-certified contextual Bayesian optimization module that adapts the parameters as a function of operating context (speed, load proxy, and temperature proxy). A barrier-function-based safety filter runs at the servo rate to enforce constraint handling during operation; its effect is evaluated empirically through logged interventions and constraint statistics. Experimental evaluation on a cycloidal joint testbed across multiple speeds and load levels shows attenuation of the dominant mesh-order vibration component and its harmonics. Tracking accuracy and safety-related signals remained within preset limits during the tested operating conditions. The proposed approach provides a deployable pathway for online vibration minimization in cycloidal robot joints without requiring high-fidelity internal contact models, and its logged parameter trajectories and order-tracked metrics also offer a foundation for condition-aware adaptation over long-term operation.","url":"https://pubmed.ncbi.nlm.nih.gov/42472878/","authors":["Alzaydi AA"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 19","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42471531","name":"Robotic-arm assistance in revision total hip arthroplasty improves the accuracy of acetabular component positioning: a cadaver-based study.","source":"pubmed","abstract":"Acetabular component positioning is a key factor for stability, impingement, wear, and biomechanics in revision total hip arthroplasty (THA).

Here I examine sex-specific sensitivity to the temporal structure of audio-visual displays in the starling Sturnus vulgaris. Using a robotic taxidermic model in field conditions, I examined early reflexive reactions to distinguish how each sex binds song and wing movements into perceptual events. I manipulated the temporal relationship between these components while keeping the signals identical. The results reveal systematic sex differences in sensitivity to temporal shifts. While adding a visual component to an acoustic baseline triggered renewed responses in both sexes, only females showed dishabituation when the timing between familiar modalities was altered. Males failed to react to those shifts even at a low-cost reflexive level. These findings reveal systematic sex differences in sensitivity to audio-visual temporal structure that are evident even in early reflexive responses. I conclude that sex differences in social behaviour can arise before downstream motivational and decision-making processes, identifying early signal processing as an additional source of receiver specialization.","url":"https://pubmed.ncbi.nlm.nih.gov/42469364/","authors":["Ręk P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 17","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42467246","name":"Key principles for rehabilitation of critically ill patients with obesity.","source":"pubmed","abstract":"Patients with obesity who are admitted to an ICU bring specific challenges for rehabilitation during and after critical illness.

Here, we present a comprehensive binder-centered perspective for LM composites, establishing the binder as a key regulator of electro-chemo-mechanical coupling, interfacial stability, transport behavior, and processability in soft energy systems. We show that tailored binder chemistries in Ga-based LM systems-including stretchable batteries, printable conductors, and soft electrochemical devices-govern LM droplet dispersion, suppress coalescence and leakage, and preserve conductive percolation under large deformation, while enabling room-temperature fabrication and printability through rheological regulation and interfacial wetting. Beyond mechanical confinement, emerging binder functionalities-including dynamic bonding, supramolecular interactions, ionically conductive networks, and reversible polymer architectures-enable self-healing interfaces, adaptive transport pathways, and robust adhesion in deformable devices. By integrating recent advances in stretchable batteries, flexible supercapacitors, printable electronics, and multifunctional soft energy systems, we establish a unified multiscale framework linking binder molecular design to device-level electrochemical and mechanical performance. We further discuss sustainability and manufacturing considerations, including recyclable polymer networks, low-temperature fabrication, and scalable processing strategies. Finally, we outline current challenges and future opportunities toward programmable binder systems with tunable viscoelasticity, interfacial reactivity, and adaptive functionality. This Review establishes binder-centered engineering as a key pathway for transforming LM composites from proof-of-concept materials into resilient, manufacturable, and multifunctional soft energy technologies for wearable, stretchable, and biointegrated electronics.","url":"https://pubmed.ncbi.nlm.nih.gov/42452106/","authors":["Parvini E","Hajalilou A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 2","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42451916","name":"Current Developments in the Use of FDM 3D-Printed Materials for Efficient Heat Transfer Applications.","source":"pubmed","abstract":"This work investigates the potential of additive manufacturing (AM) technologies for prototyping and developing functional components in thermal systems, with particular emphasis on thermal and mechanical performance. The study focuses on two complementary prototyping strategies: (i) the use of metal-filled polymer filaments in Fused Deposition Modeling (FDM), also known as Material Extrusion (MEX) according to ISO/ASTM 52900:2022, and (ii) a hybrid approach combining polymer 3D printing with conductive coating and electrochemical copper deposition. While metal-filled filaments provide a rapid and low-cost solution for early-stage prototyping, their mechanical properties remain similar to those of the polymer matrix, limiting their applicability in load-bearing structures. In contrast, the hybrid method enables the fabrication of hollow metallic geometries with improved thermal and electrical conductivity. This approach is more time-consuming and process-intensive and is therefore considered a subsequent stage in the prototyping workflow following initial MEX-based design iterations. Compared with conventional polymer-based MEX, several AM approaches enable the development and fabrication of fully metallic or metal-functional structures, including Powder Bed Fusion (PBF), Directed Energy Deposition (DED), and hybrid polymer-metal methods based on electroplating. Furthermore, understanding mechanical properties such as tensile strength is essential for assessing the applicability of AM materials in energy system components. The results contribute to bridging the gap between rapid prototyping and the implementation of advanced AM technologies in thermal-related applications.","url":"https://pubmed.ncbi.nlm.nih.gov/42451916/","authors":["Madejski P","Raza A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 3","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42451466","name":"A Carbon Trace Detection Method for Oil-Immersed Transformers Based on Superimposed Illumination Estimation and Multi-Scale Feature Fusion.","source":"pubmed","abstract":"Accurately locating and reliably diagnosing insulation defects in oil-immersed transformers remains challenging. To overcome this, a micro-robot is employed to autonomously identify partial discharge (PD)-induced carbon traces on the insulation surface of the core components. Accurately capturing the multi-scale complex features of surface-discharge carbon traces under low-illumination conditions is critical for effective defect detection. Therefore, to address the obscurity of carbon trace features caused by insufficient illumination inside oil-immersed transformers, a Retinex-based image enhancement algorithm with superimposed illumination estimation is proposed. By transforming the original image into the HSI color space and integrating negative-image illumination fusion, this algorithm decouples brightness from chromaticity and preserves dark-region details, thereby reducing color distortion and enhancing carbon trace features. Furthermore, to handle the significant scale variations in carbon traces, a C2f module integrated with spatial and channel synergistic attention (SCSA) is designed. This module employs multi-scale depthwise separable convolutions and wide-channel self-attention to enhance cross-scale feature representation and reduce redundancy. Moreover, to address the feature resolution degradation in the fast spatial pyramid pooling module, which hinders the accurate perception of tiny carbon traces, a poly kernel inception atrous spatial pyramid pooling module (PKI-ASPP) is adopted. This preserves precise morphological details and minimizes the missed and false detection rates for tiny carbon traces. Finally, to tackle the difficulties in fusing complex morphological features, a deformable large kernel attention (DLKA) module is introduced into the neck network. This adapts to irregular carbon trace shapes, significantly improving the localization and learning of complex morphologies. Experiments on a transformer PD carbon trace dataset demonstrate that the proposed model significantly improves perceptual capabilities for carbon traces with massive scale variation. The improved model outperforms the baseline across all evaluation metrics, with mAP50 improved by 2.7% and mAP50-95 improved by 7.9%. These results indicate that the proposed method is highly reliable, providing solid technical support for internal surface discharge intensity detection and insulation condition assessment in oil-immersed transformer maintenance.","url":"https://pubmed.ncbi.nlm.nih.gov/42451466/","authors":["Ji H","Shi Z","Li J","Liu X","Liu L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 3","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42451325","name":"Influence of Specimen Size and Test-Opening Geometry on the Sound Reduction Index Measured in Small-Scale Coupled Reverberation Rooms.","source":"pubmed","abstract":"The sound reduction index R is commonly determined using standardized laboratory procedures developed primarily for full-size building elements. However, in many research and development applications, including technical enclosures, lightweight panels, modular components, and new acoustic materials, only reduced-size specimens are available. In such cases, the influence of specimen dimensions and test-opening geometry on the measured sound insulation is not yet fully understood. This study investigates the effect of specimen size and geometry on the measured sound reduction index using a dedicated small-scale coupled reverberation room stand. Measurements were performed for five materials with different mechanical and structural properties: steel, polymethyl methacrylate (PMMA), medium-density fiberboard (MDF), gypsum board, and Sylomer. Six test openings were analyzed, including three square openings, one quasi-square opening, and two rectangular openings. The results show that specimen dimensions can significantly affect the measured values of R , especially in the low-frequency range, where modal behavior, boundary conditions, and the relationship between specimen dimensions and acoustic wavelength are important. The influence of specimen size was material-dependent and was more pronounced for stiff plate-like materials than for the highly compliant Sylomer specimen. Comparisons between square and rectangular openings with similar surface areas suggest that, within the investigated range of materials, specimen geometries, and measurement conditions, specimen surface area had a greater influence on R than specimen shape, although geometry can still contribute to the measured differences. The repeatability analysis confirmed that the measurement stand is sensitive to differences related to material type, specimen dimensions, and installation conditions. The proposed methodology may be particularly useful for comparative studies of novel acoustic materials and prototype building elements when only reduced-size specimens are available during the early stages of material development. The results support the use of small coupled reverberation rooms for comparative testing and preliminary material screening, while also showing that reduced-size sound insulation measurements require careful interpretation and cannot be treated as direct substitutes for full-scale standardized tests.","url":"https://pubmed.ncbi.nlm.nih.gov/42451325/","authors":["Polaczek A","Baruch-Mazur K","Młynarczyk D"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jun 27","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"pmid:42451259","name":"Precision Livestock Farming and Biomedical Engineering: Assessing Feed Quality, Animal Health, and Behavior Using Machine Learning for Sensor Data.","source":"pubmed","abstract":"This review analyses and logically structures modern intelligent sensor technologies in the context of animal husbandry, feed production, and veterinary medicine. The main research discussed in the article focuses on machine learning based on modern neural network models, computer vision, and sensor systems that are transforming the methods for assessing the health, behavior, and nutrition of farm animals. The first part examines modern approaches to quality control and optimization of mineral and vitamin premixes, including visual inspection using visual sensors and neural networks. Key roles are played by precise dosing, component stability (minerals, vitamins), and the transition to more bioefficient organic forms of micronutrients to reduce environmental impact. Improvements in feed and premix production are analyzed, including automation, energy management, and the use of machine learning for non-destructive quality control, defect detection, mixing homogeneity assessment, and vitamin stability prediction. The second part analyzes methods for animal location and behavior detection. This article presents computer vision-based systems, including modifications of YOLO, for automatically tracking and classifying key behavioral patterns (lying down, standing, feeding, and aggression) in cattle and pigs, even in crowded conditions. It also discusses the use of ultra-wideband (UWB) systems and accelerometers combined with machine learning for high-precision positioning and detection of specific behavioral anomalies, such as lameness and playfulness. The third section focuses on the application of machine learning in veterinary diagnostics, including the automated interpretation of medical images (X-ray, ultrasound, and MRI) as sensor data streams for the diagnosis of cardiovascular, oncological, and orthopedic diseases in farm and small animals. Furthermore, the article examines the use of machine learning models for proactive disease diagnosis in farm animals and poultry based on multimodal data and image analysis. Considerable attention is given to methods and tools for radiometric diagnosis of animal diseases at an early stage using microwave sensors, as well as laser therapy and surgery in veterinary medicine.

Specifically, we perform FEM simulations and desktop-scale experiments to determine the instability thresholds for different geometrical parameters. We first test our models against self-buckling results without pressure for solid rods and hollow cylindrical tubes, and then proceed to determine the critical buckling pressure for a set of material and geometrical parameters. We find that positive internal pressures can stiffen cylinders that are unstable under their own weight, leading to an effective Young's modulus that we show scales linearly with the applied pressure. On the contrary, cylinders that are stable under self-weight, buckle under a negative pressure, resembling classical results on pressure-induced ring buckling.

This narrative review examines the artistic dimensions of orthopaedic surgery, with particular emphasis on hand and upper extremity procedures in which form and function are inextricably linked. We trace the historical evolution of surgical artistry from Renaissance anatomists and craftsmen, including Ambroise Pare, whose articulated prosthetic hands united the ingenuity of locksmiths with the vision of surgeons, through nineteenth-century operative theatre culture, in which surgical skill was evaluated for its elegance and grace as much as its outcomes, to modern microsurgery and the age of robotics. Drawing on a systematic review of peer-reviewed sources spanning anatomy, reconstructive surgery, outcomes research, and the philosophy of craft, we analyse the application of core artistic principles, proportion, symmetry, harmony, rhythm, and balance, to surgical practice, demonstrating that these concepts provide a functional framework for operative decision-making, technique selection, and outcome evaluation. The surgeon's role extends beyond technical competence to encompass aesthetic judgment, creative problem-solving, spatial visualisation, and an appreciation for the beauty inherent in anatomical restoration. Specific techniques in hand and upper extremity surgery are examined as case studies of artistic principle applied to clinical practice: toe-to-hand microsurgical transfer, soft-tissue flap coverage, fingertip and nail reconstruction, scar management, rheumatoid hand reconstruction, and congenital deformity correction each illustrate how aesthetic refinement and functional restoration are not competing objectives but mutually reinforcing goals. Patient-reported outcomes related to aesthetic satisfaction are evaluated through validated measures including the Patient and Observer Scar Assessment Scale (POSAS), with evidence confirming that hand appearance constitutes a significant determinant of patient satisfaction, psychological well-being, and quality of life (QoL). The education of the surgeon's hand, through apprenticeship, deliberate practice, and embodied tactile experience with instruments, is identified as an irreplaceable component of surgical formation that no technological advance can render obsolete. We conclude that excellence in orthopaedic surgery demands mastery of three interrelated domains: scientific knowledge, technical skill, and artistic sensibility. Future directions include the formal integration of aesthetic training into surgical curricula, development of objective aesthetic outcome metrics, expanded use of three-dimensional imaging for aesthetic planning, and institutional recognition of the artistic dimensions of surgical practice as essential components of comprehensive, patient-centred care.","url":"https://pubmed.ncbi.nlm.nih.gov/42434621/","authors":["Salem-Hernández J","Luigi-Martinez HE","Rodriguez-Reyes D","Ramírez N","Bossolo J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jun","addedAt":"2026-08-06T15:50:27.715Z"},{"id":"doi:10.1007/s11701-026-03582-4","name":"Progress and perspectives in soft robotics for surgery and rehabilitation.","source":"europepmc","abstract":"","url":"https://doi.org/10.1007/s11701-026-03582-4","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1007/s11701-026-03582-4","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.3389/frobt.2026.1751222","name":"Operationalising reproducibility in soft robotics.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1751222","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.3389/frobt.2026.1751222","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1016/j.cis.2026.103911","name":"Autonomous soft robotics: Revolutionizing motion with intelligence and flexibility.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.cis.2026.103911","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1016/j.cis.2026.103911","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1126/scirobotics.aee0269","name":"The codevelopment of soft robotics and assistive technology.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/scirobotics.aee0269","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1126/scirobotics.aee0269","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1016/j.euf.2026.06.031","name":"Challenges for Developing a Soft Robotics Solution for the Surgical Treatment of Stress Urinary Incontinence in Women.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.euf.2026.06.031","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1016/j.euf.2026.06.031","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.3390/biomimetics11030193","name":"Granular Jamming in Soft Robotics: Simulation Frameworks and Emerging Possibilities-Review.","source":"europepmc","abstract":"Soft robotics has become a dynamic field that emphasizes adaptability and safe interaction with complex environments. These structures utilize deformable materials and continuum mechanics to adapt their shape, absorb shocks, and perform tasks in unstructured environments.

In this paper, we address the role of simulation frames as an important tool for understanding, designing, and extending the functionality of software robotic devices utilizing granular jamming. The analysis suggests that DEM is essential for capturing particle-level mechanisms, while FEM is more effective for system-level optimization but tends to smooth out the transition of jamming.

Morphometric analyses of live specimens revealed strong differentiation between body regions: trunk length remains nearly constant during motion (7.26 ± 3.40 mm retracted vs. 7.70 ± 3.47 mm extended), whereas total body length more than doubles (from 8.87 ± 4.30 mm to 18.75 ± 7.35 mm), driven by introvert eversion at the tip. Tensile tests further highlighted distinct mechanical properties, with the trunk sustaining substantially higher strains before failure (≈ 90–110%) compared to the introvert (≈ 60–65%). Peristaltic locomotion was investigated using a mathematical model reproducing wave-like propulsion in unsegmented bodies at characteristic speeds of 0.5–5 mm s⁻¹ in confined media and showing close agreement with experimental observations. As an exemplary translation of these mechanisms, a soft robotic architecture based on magneto-responsive silicone was developed enabling stimulus-driven protrusions up to 2.5 times the initial length. Overall, this study provides a biologically grounded framework for innovative soft robotic systems inspired by unsegmented worms.","url":"https://doi.org/10.1038/s41598-026-44047-w","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1038/s41598-026-44047-w","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.20944/preprints202605.0017.v1","name":"Pneumatics in Service Robotics: A Review Across Application Domains and the Impact of Soft Robotics","source":"europepmc","abstract":"","url":"https://doi.org/10.20944/preprints202605.0017.v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.20944/preprints202605.0017.v1","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1002/marc.70307","name":"Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing-Centric Review.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/marc.70307","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1002/marc.70307","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1088/1748-3190/ae6e83","name":"Tailoring silicone mixtures for soft robotics: predictive modeling and experimental validation in pneumatic soft actuators.","source":"europepmc","abstract":"","url":"https://doi.org/10.1088/1748-3190/ae6e83","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1088/1748-3190/ae6e83","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1088/1748-3190/ae066d","name":"Soft robotics: what's next in bioinspired design and applications of soft robots?","source":"europepmc","abstract":"","url":"https://doi.org/10.1088/1748-3190/ae066d","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1088/1748-3190/ae066d","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1021/acsami.5c16200","name":"Bioinspired Flexible Tactile Sensors for Smart Soft Robotics.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsami.5c16200","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1021/acsami.5c16200","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1002/smll.202512044","name":"Ionic Wind Cooling Enables High-Frequency Shape Memory Alloy Actuators for Origami-Inspired Soft Robotics.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/smll.202512044","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1002/smll.202512044","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1016/j.ebiom.2025.106031","name":"Embodiment as outcome: the translational test for soft robotics.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.ebiom.2025.106031","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1016/j.ebiom.2025.106031","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1177/21695172251364758","name":"Soft Robotics for Space Applications: Cryogenic Performance of Modular Metallic Cable Structures.","source":"europepmc","abstract":"","url":"https://doi.org/10.1177/21695172251364758","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1177/21695172251364758","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1002/adma.202504683","name":"Thermally Actuated Soft Robotics.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/adma.202504683","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1002/adma.202504683","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1002/advs.202523532","name":"Soft Robotics and Advanced Technologies for Minimally Invasive Bioprinting: The Future of Internal Organ Repair.","source":"pubmed","abstract":"Bioprinting, first proposed in the 1980s for ex vivo tissue fabrication, has evolved into a cornerstone of regenerative medicine. Conventional approaches rely on printing tissues outside the body for later implantation but are limited by geometric mismatch, construct fragility, and invasive surgery. In situ bioprinting addresses these limitations by depositing cells and biomaterials directly at defect sites, enabling patient-specific repair and improved tissue integration. Building on this paradigm, Minimally Invasive Bioprinting (MIB) targets internal organ regeneration through small incisions or natural orifices. This review defines a technological roadmap from handheld bioprinting tools to advanced MIB systems, identifying soft robotics as the primary hardware enabler for navigation within confined anatomical environments. We examine essential technology pillars for MIB, including soft actuation, sensing, real-time imaging, computational modeling, intelligent control, and bioink engineering. The integration of emerging approaches such as artificial intelligence, four-dimensional bioprinting, and organ-on-a-chip platforms is discussed for enhancing autonomy, adaptability, and functional outcomes. Finally, we evaluate key translational challenges, including safety, scalability, and reproducibility, and outline regulatory considerations for clinical implementation.

Flexible transparent conductive films offer a promising route for strain-based proprioception and visible light communication, but maintaining stable conductivity and high transparency under large deformations remains challenging. Here, An ion-electron fusion film is presented, termed i-PEDOT:PSS, comprising a poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS) layer on an ionic substrate. The interfacial ion penetration, in combination with the pre-formed microcrack structure, imparts i-PEDOT:PSS with robust conductivity and desirable strain-sensing capability under large strain. The i-PEDOT:PSS achieves a highly linear and repeatable electromechanical response over strains up to 300%, approximately three times that of previously reported transparent strain sensors, while maintaining an optical transmittance of 93%. Benefiting from these properties, i-PEDOT:PSS serves as a multifunctional component in soft robotic systems.

SMPs have attracted significant interest for biomedical devices and soft robotics due to their large recoverable strains, programmable mechanical and thermal properties, tunable activation temperatures, responsiveness to various stimuli, low density, and ease of processing via additive manufacturing techniques, as well as demonstrated biocompatibility and potential bioresorbability. This review summarises recent progress in the fundamentals, classification, activation mechanisms, and fabrication strategies of SMPs, focusing particularly on design principles that influence performance relevant to specific applications. Both thermally and non-thermally activated SMP systems are discussed, alongside methods for controlling activation temperatures, including plasticisation, copolymerisation, and modulation of cross-linking density. The use of functional nanofillers to enhance thermal and electrical conductivity, mechanical strength, and actuation efficiency is also considered. Current manufacturing techniques are critically evaluated in terms of resolution, material compatibility, scalability, and integration potential. Biodegradable SMPs are highlighted, with discussion of degradation behaviour, biocompatibility, and demonstrations in devices such as haemostatic foams, embolic implants, and bone scaffolds. However, despite their promising potential, the widespread application of SMPs faces several challenges, including non-uniform activation, the need to balance mechanical strength with shape recovery, and limited standardisation.

MnO 2 is a promising cathode material due to its environmental friendliness and low cost, but it faces challenges related to low conductivity and structural instability. Herein, a single-element (Ce) heterovalent doping strategy is proposed to boost the capacity and structural stability of &#x3b4;-MnO 2 (Ce-MnO 2 ). Ce 4+ can preferentially occupy the Mn sites due to its same and stable valence state as Mn 4+ , effectively suppressing structural collapse during charge and discharge processes. Ce 3+ could contribute to improved electronic conductivity through aliovalent substitution, leading to charge compensation and altering the local chemical environment by creating oxygen vacancies and optimizing Mn-O interactions. Moreover, it can improve the specific surface area and provide active sites, thereby promoting electrochemical activity and facilitating superior ion transport. Consequently, the Ce-MnO 2 cathode achieved a high specific capacity of 374.5 mAh g -1 , with 90% capacity retention after 1000 cycles.

electronics developed so far, it should be noted that a majority of them need a reservoir for electrical energy storage. Unfortunately, most off-the-shelf devices commercially available nowadays are based on rigid parts that heavily limit the possibilities of incorporating such products into soft robots and wearable electronics. To address these issues, a new type of flexible structure for electrical energy storage, which consists of small battery cells connected by liquid metal paths, was proposed. It can achieve a low value of Young’s modulus (about 0.13 MPa) while maintaining electrochemical stability for large stretches (max. capacity reduction—2%). We proposed an individual layer structure as well as a sandwich structure with a granular core, which by way of granular jamming phenomena can change the stiffness (almost 300%). This article describes the concept and working principle of the proposed flexible electrical energy storage structure, followed by the mechanical and electrical characterization, electrochemical impedance spectroscopy, and galvanostatic battery cell cycling. Scanning electron microscopy and energy-dispersive X-ray spectroscopy were used to characterize the electrodes. The article also includes numerical simulations and potential applications of the studied structure.","url":"https://doi.org/10.1089/soro.2024.0098","authors":["Piotr Bartkowski","Łukasz Pawliszak","Agata Lusawa","Sabina Sypniewska","Marta Ciemiorek","Yong-Lae Park"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024-12-24T12:24:36Z","addedAt":"2026-08-06T15:53:30.372Z","doi":"10.1089/soro.2024.0098","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1021/acsnano.3c04089","name":"Sensing in Soft Robotics.","source":"pubmed","abstract":"Soft robotics is an exciting field of science and technology that enables robots to manipulate objects with human-like dexterity. Soft robots can handle delicate objects with care, access remote areas, and offer realistic feedback on their handling performance. However, increased dexterity and mechanical compliance of soft robots come with the need for accurate control of the position and shape of these robots. Therefore, soft robots must be equipped with sensors for better perception of their surroundings, location, force, temperature, shape, and other stimuli for effective usage. This review highlights recent progress in sensing feedback technologies for soft robotic applications. It begins with an introduction to actuation technologies and material selection in soft robotics, followed by an in-depth exploration of various types of sensors, their integration methods, and the benefits of multimodal sensing, signal processing, and control strategies.

Since most currently under-development soft robotic systems are composed of polymeric or elastomeric materials, this finding may provide immediate assistance to the community developing soft robots. Self-healing and damage-resilient systems are making their way into actuators, structures, and sensors, even if soft robotics remains in its infancy.

To address this, we explicitly model the decision-making context and identify it with dedicated observers running in parallel to the task execution. Observer behaviors are implemented as behavior trees and coordinated by a centralized context manager. We validate the approach on a mobile manipulator that performs autonomous machine-tending tasks in a real medical laboratory, as well as during a public trade fair. Experimental results show that context-driven observers can robustly identify decision-making context without interfering with ongoing actions. Furthermore, parallelized perception leads to substantial runtime improvements, achieving overall task time savings of up to 24 % .

A retrospective analysis was conducted on 44 patients who underwent RTAT for MNG. Patients were stratified into three groups based on thyroid volume: Small (&lt;30 mL), Medium (30-60 mL), and Large (&#x2265;60 mL). The da Vinci Xi Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) was utilized following a standard institutional protocol. Hypocalcemia data were available for 43 patients: 22 of 23 in the Small group, 15 of 15 in the Medium group, and 6 of 6 in the Large group. Statistical analyses were performed to compare group outcomes. The cohort (N = 44) was stratified into Small (n = 23), Medium (n = 15), and Large (n = 6) groups (Figure 1). The overall robotic completion rate was 97.7% (43/44), with one conversion to open surgery (2.3%). Operative time significantly increased with larger goiter volumes (Small: 142.1 &#xb1; 28.9 min, Medium: 165.3 &#xb1; 38.1 min, Large: 180.5 &#xb1; 30.7 min; P = 0.015).

Briefing commenced at 07:30; knife-to-skin at 07:45. List 1 completed by 13:30 - ten major resections in 5&#xa0;h 45&#xa0;min - with actual turnaround of 2-3&#xa0;min between cases. All 15 procedures were completed (list completion 100%). Median console time was 35&#xa0;min (range 23-56). All resections achieved R0 status. Complications occurred in 5 of 15 patients (33%): three grade II, one grade IIIb, one grade IVa by the Clavien-Dindo classification. Median length of stay was 4 days (range 1-30). Thirty-day and 90-day mortality were nil. This is the first description of a HIT list for major anatomical thoracic resection. The model was feasible and did not raise unexpected safety concerns in this initial experience, delivering a marked increase in theatre throughput without expanding resource. Prospective multicentre evaluation is warranted before wider adoption.","url":"https://pubmed.ncbi.nlm.nih.gov/42557507/","authors":["Berjaoui N","Pather M","Arif F","Johnstone C","Christodoulides G","Abdalla H","Ahmed I","AlShammari A","Choi JS","Routledge T","Patel A","Bille A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Aug 6","addedAt":"2026-08-06T15:53:30.372Z"},{"id":"pmid:42557484","name":"Artificial intelligence-supported segmentation of cardiac anatomy in open-heart surgery videos.","source":"pubmed","abstract":"Accurate identification of anatomical structures is essential for safe congenital cardiac surgery and for the development of assistive robotic systems.

A literature search was conducted using PubMed/MEDLINE, Embase, Scopus, Web of Science Core Collection, and the Cochrane Library to identify relevant English-language publications through May 2026. Early robotic systems established the feasibility of robotic thoracic procedures, particularly mediastinal surgery and selected pulmonary resections, while also defining the technical limitations that shaped early practice, including demanding docking, arm-collision issues, dependence on bedside assistance, and lack of console-controlled stapling. The da Vinci Xi refined multiport robotic surgery through improved arm design, overhead boom architecture, simplified docking, and integrated stapling, supporting greater standardization and broader adoption of robotic thoracic surgery. In parallel, reduced-port approaches, including biportal and uniportal RATS, emerged through technical adaptation of existing platforms. The da Vinci SP introduced a dedicated single-port architecture, whereas the da Vinci 5 represents a further step toward haptic feedback and data-driven robotic surgery. Emerging systems such as Versius, Hugo RAS, Toumai, and Shurui SP reflect a diversifying robotic landscape, with modular, portable, and lower-cost design, that may influence future access and adoption. Future developments include artificial intelligence, augmented reality, digital twins, autonomous assistance, and remote surgery.

Movement-related pain may be particularly relevant because it occurs during passive knee training, walking, and weight-bearing activity. Navigation and robotic systems can help the surgeon plan bone cuts, place implants, and balance soft tissue. However, surgeons still do not know whether these tools lower the overall pain burden during early recovery. This point is especially important for pain that appears during movement. This study compared early pain after conventional, navigation-assisted, and robotic-assisted TKA. We used the area under the curve (AUC) to describe cumulative pain from 24 to 72&#xa0;h after surgery. We retrospectively reviewed 169 patients undergoing primary unilateral TKA from April 2025 to April 2026. Patients were grouped as conventional (n&#x2009;=&#x2009;78), navigation-assisted (n&#x2009;=&#x2009;39), or robotic-assisted TKA (n&#x2009;=&#x2009;52). The primary outcome was the 24-72 h area under the curve (AUC) of visual analogue scale (VAS) pain during passive knee flexion-extension. Secondary outcomes included resting pain AUC, time-point VAS scores, walking pain at discharge, rescue analgesic frequency, morphine-equivalent consumption, early range of motion, swelling, quality of recovery, 3-month Knee Society Score, hospital stay, and complications. Multivariable regression adjusted for measured confounders. The study included 169 patients. Seventy-eight patients received conventional TKA, 39 patients received navigation-assisted TKA, and 52 patients received robotic-assisted TKA. The three groups had similar measured baseline features. Resting-pain AUC from 24 to 72 h did not differ among the groups. Passive-motion pain AUC differed significantly among the groups. The robotic-assisted group had a lower cumulative movement-related pain burden than the conventional group. The navigation-assisted group showed a lower AUC estimate, but this difference was not significant after adjustment. The difference between the robotic-assisted and navigation-assisted groups was not significant. Passive-motion VAS at 36 and 48 h was lower after robotic-assisted TKA than after conventional TKA. Walking pain at discharge was also lower in the robotic-assisted group. The groups did not differ in rescue analgesic frequency, morphine-equivalent rescue analgesic consumption, knee swelling, ROM recovery, QoR-15, length of stay, complications, or 3-month KSS. Robotic-assisted TKA was associated with lower early movement-related pain burden than conventional TKA, but the absolute time-weighted VAS difference was modest.

A systematic search of PubMed, the Cochrane Library, and ClinicalTrials.gov was conducted from database inception to July 4, 2026. Studies involving adult women undergoing SPRNSM for therapeutic or prophylactic indications were included. Both clinical and cadaveric studies reporting relevant outcomes were eligible. Study selection and data extraction were performed independently by two reviewers. Risk of bias was appraised using the ROBINS-I tool. Due to heterogeneity, results were synthesized narratively. Sixteen studies were included, comprising seven retrospective studies, one prospective study, five case reports, two case series, and one cadaveric study. SPRNSM was technically feasible across all studies, with no reported conversions to conventional surgery. Operative times were significantly longer than conventional nipple-sparing mastectomy (mean differences of 54-70&#xa0;min) but comparable to multi-port robotic approaches. Grade III or higher complications ranged from 1.8% to 20%, with reoperation rates from 1.4% to 7.5%. Nipple-areolar complex necrosis rates were consistently low (1.2%-2.5%) and patient-reported satisfaction and sensory preservation were favorable. Short-term oncological outcomes appeared comparable to conventional techniques, although follow-up was limited to a maximum of 36 months. Overall risk of bias was serious for 80% of clinical studies. Current evidence suggests that SPRNSM is a feasible and safe procedure with potential cosmetic and functional advantages. However, the evidence base is limited by predominantly retrospective designs, small sample sizes, selection bias toward high-volume centers, and short follow-up, preventing definitive conclusions regarding long-term oncologic safety.

A critical methodological caveat applies to this comparison: the two surgical arms differ simultaneously in navigation modality, fracture reduction technique, and soft tissue dissection extent; observed intergroup outcomes cannot be attributed solely to robotic technology.

This single-center retrospective consecutive cohort study enrolled 80 patients aged 18-65 years with femoral neck fractures treated between January 2023 and December 2024; 40 patients underwent Ti-Robot-assisted percutaneous FNS fixation, and 40 received conventional open reduction FNS fixation. Primary outcome measure was the Harris Hip Score (HHS) collected at 6, 12, and 18 months postoperatively. Secondary outcomes included total operative duration, intra-operative blood loss, fluoroscopic imaging metrics (total shot count&#x2009;+&#x2009;cumulative screening time), postoperative CT implant trajectory deviation, bolt angular parallelism error, first-attempt screw placement success rate, serial 0-10 VAS pain scores, institutional hospital length of stay (LOS), and 18-month fracture-related complication incidence. All participants completed full 18-month clinical and imaging follow-up. Statistical analyses were performed using Python; normality-directed variable-specific testing was applied, with no formal correction conducted for multiple secondary outcome comparisons.

Two field studies were conducted. Study 1 (N = 220) is a two-wave lagged survey for employees in logistics industry. The results indicated that human-robot collaboration affects OCB through cobot identity and emotional exhaustion, as well as their chain mediating pathways. Study 2 (a three-wave lagged survey; N = 294) expanded the sample to the entire manufacturing industry. It confirmed the results of Study 1 and provided further validation of the moderating effect of openness. When openness is high, the direct effect and indirect effects of human-robot collaboration on OCB are amplified. This research provides organizations with the means to establish effective human-robot collaboration and guides employees to make more OCB.","url":"https://pubmed.ncbi.nlm.nih.gov/42554231/","authors":["Duan WY","Cui XX","Wu TJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Aug 5","addedAt":"2026-08-06T15:53:30.372Z"},{"id":"pmid:42553998","name":"Enabling Controlled Sliding and Multi-Modal Sensing in an Anti-Swelling, Muscle-Inspired Hydrogel via Multiple Cross-Linking.","source":"pubmed","abstract":"The development of hydrogel-based flexible sensors is hindered by their inherent swelling and performance degradation in physiological environments.

Existing approaches often rely on stationary environmental models or loosely coupled planning frameworks that do not fully exploit model uncertainty when generating feasible trajectories. To address these limitations, we propose a closed-loop informative path planning (IPP) framework that tightly integrates environmental modeling and trajectory generation for autonomous sampling. The proposed approach combines a nonstationary uncertainty representation using Gaussian Process Regression with Attentive Kernels (AK-GPR), uncertainty- guided adaptive sampling, and a Dubins-constrained RRT* planner to generate dynamically feasible and information-rich trajectories. The proposed framework is evaluated through staged experiments, including simulation and field validation, across representative ecological monitoring scenarios such as algal plume tracking, bathymetric mapping, and seagrass probability estimation. The results demonstrate that the proposed planner shows improved performance relative to the baseline planners in different initialization grid densities, with particularly strong performance in scenarios with limited prior information. In all environments, the proposed IPP framework achieved an average reduction of approximately 24% in mean absolute error (MAE) and 32% in predictive uncertainty compared to baseline planners, with improvements reaching up to 33% in MAE and 42%, respectively, in sparse initialization settings. These results demonstrate the benefits of a tightly coupled framework that balances uncertainty reduction and spatial coverage, enabling more efficient environmental exploration under realistic vehicle constraints.","url":"https://pubmed.ncbi.nlm.nih.gov/42553069/","authors":["Chavez-Galaviz J","Bloss M","Mahmoudian N"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.372Z"},{"id":"pmid:42552962","name":"Development and Upgrade of a Robot That Enables Three-Dimensional Trunk Motion and Lower Limb Exercise for Stroke Patients: A Pilot Clinical Investigation Including a User Feasibility Test.","source":"pubmed","abstract":"Stroke impairs functional independence including gait ability.

To evaluate this approach, we analyzed multimuscle MEP datasets from three experiments in healthy young adults focusing on different stimulus parameters: stimulus intensity ( experiment 1: n = 40), motor mapping size ( experiment 2: n = 35), and activation of intracortical circuits by a paired-pulse TMS paradigm ( experiment 3: n = 20). We extracted motor-evoked modules (MEMs) using non-negative matrix factorization (NMF) and compared their structure across different stimulus conditions. MEM structure was impacted by stimulus intensity, and these findings indicate that stimulus intensity shapes the pattern-level structure of corticospinal outputs. Varying motor mapping size had only a minor impact on MEM structure, suggesting that the pattern-level structure of corticospinal outputs elicited by TMS was stable across mapping extents. Activation of intracortical inhibition appeared to alter MEM structure compared with single-pulse TMS. These findings suggest that paired-pulse activation of intracortical inhibition may alter the pattern-level structure of corticospinal outputs. The MEM framework allows us to characterize the pattern-level structure of corticospinal outputs beyond single-muscle MEPs; thus, MEMs obtained from TMS complement well-established single-muscle MEP analyses and offer a novel perspective for investigating the motor system.","url":"https://pubmed.ncbi.nlm.nih.gov/42552671/","authors":["Morishita T","Coscia M","Bacigalupo M","Lassi M","Proulx CE","Fleury L","Hummel FC"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Aug 4","addedAt":"2026-08-06T15:53:30.372Z"},{"id":"pmid:42552668","name":"Mul-PheG2P: decoupled learning and prediction-space fusion enables robust and interpretable multi-phenotype genomic prediction.","source":"pubmed","abstract":"Genomic prediction of multiple phenotypes is crucial in modern plant breeding; however, existing methods struggle with negative transfer and lack interpretability, particularly across high-dimensional small-sample data and diverse species.

Bibliometrics can systematically and quantitatively summarize research achievements, key research directions, and emerging trends in this field, thereby guiding future research efforts on the application of robot-assisted surgery in vascular surgery. All eligible literature in this research was retrieved from the Web of Science Core Collection, covering publications released from 1997 to 2025 that focus on the clinical applications of robot-assisted surgery within vascular surgery. Two bibliometric software programs, VOSviewer 1.6.20 and CiteSpace 6.4.R2, were adopted to implement multiple analytical procedures, including author collaboration analysis, literature co-citation analysis and keyword co-occurrence analysis. Meanwhile, the citation burst detection function embedded in CiteSpace was applied to pinpoint prevailing research hotspots and emerging frontiers in this discipline. This study included 375 eligible publications from 1,777 researchers across 503 institutions in 39 countries. Annual publication output showed a steady increase, with two notable peaks in 2022 and 2025 after a marked rise post-2020.

Temporal keyword analysis revealed a clear shift from traditional open cardiovascular procedures (e.g., coronary artery bypass grafting, laparoscopic aortic bypass) toward robotic-assisted endovascular and extravascular interventions, such as percutaneous coronary intervention and integrated robotic revascularization. Over the past twenty-nine years, China's research institutions and scholars have achieved certain accomplishments in the application research of robot-assisted surgical techniques in the field of vascular surgery.

This intersection of cardiac transplantation and urological disease presents unique clinical challenges requiring further study of optimal surgical and postoperative management. Heart transplant patients receiving lifelong tacrolimus-based immunosuppression are particularly prone to impaired wound healing and postoperative complications. The authors report a 71-year-old man who underwent heart transplantation in November 2015 for ischemic cardiomyopathy. His immunosuppressive regimen included tacrolimus (target trough 5-7 &#xb5;g/L), mycophenolate mofetil, and low-dose steroids. The patient underwent robot-assisted radical prostatectomy (RARP) with bilateral pelvic lymphadenectomy for prostate adenocarcinoma (iPSA 9.3 ng/mL).

Recovery was initially uneventful, and he was discharged on postoperative day 5, catheter-free after spontaneous micturition. Fifteen days postoperatively, the patient was readmitted with acute flank pain. Imaging demonstrated left ureteral extravasation. Review of the surgical recording excluded thermal injury during lymphadenectomy, suggesting tacrolimus-associated impaired healing as a possible cause. Management included placement of a double-J stent, antibiotics, and cardiac monitoring. Because urinary drainage remained insufficient, urinary diversion with a Mono-J stent and percutaneous nephrostomy (PCN) was performed, considering the patient's cardiologic risk profile. A cystogram&#xa0;demonstrated minimal secondary urethrovesical anastomotic insufficiency, possibly related to endourological manipulation, although tacrolimus-associated healing impairment could not be excluded. The Mono-J stent and the nephrostomy catheter were removed after 2 and 3 months, respectively, following complete ureteral healing. Secondary percutaneous radiotherapy with androgen deprivation therapy was recommended.

As social assistive robots are increasingly introduced into healthcare, questions emerge regarding the role these technologies can play in caring practices. Drawing on Katie Eriksson's theory of caritative caring, this paper examines how social assistive robots may be understood in caring and discusses the ethical boundaries that should guide their use. Caritative caring, grounded in Caritas, emphasizes human dignity, the care relationship, invitation, responsibility, virtue, obligation or duty, and ethical freedom. It presupposes an ethical orientation and relational openness that robots cannot possess as ethical subjects. Social assistive robots may simulate relational behaviors and support certain aspects of care, but they lack the moral agency and compassionate intentionality required for caritative caring in its full sense. At the same time, this does not mean that robots have no place in healthcare. When designed and used within a value-sensitive and care-oriented framework, social assistive robots may complement caregivers by supporting safety, autonomy and routine care tasks. Caritative caring theory thus offers a framework for clarifying the ethical boundaries of robot use in healthcare, not as substitutes for human compassion and responsibility, but where social assistive robots may support the conditions for human caring without replacing the relation and ethical responsibilities of caregivers.","url":"https://pubmed.ncbi.nlm.nih.gov/42542962/","authors":["Andtfolk M","Estman L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Oct","addedAt":"2026-08-06T15:53:30.373Z"},{"id":"pmid:42542955","name":"Should Care Robots Answer?

Although such systems are not moral agents in a human-like sense, their actions are embedded in social practices in which demands for explanation play a significant role. The article develops a structured analytical framework that conceptualizes answerability as comprising both a subjective dimension (the actor's reasons and justifications) and an objective dimension (the comprehensibility and moral quality of explanations). It thereby clarifies the conditions under which demands for explanation arise and how they can be normatively assessed. Applying this framework to care robots, the article argues that these systems can be meaningfully treated as answerable, even though they are not accountable-in human terms. Concrete care scenarios illustrate that affected individuals may be entitled to demand explanations from robots, despite their technically mediated and limited responses.

Although open surgery is still the standard benchmark for its long-term durability and high success rate, the development of minimally invasive techniques led to the creation of laparoscopic ureteral reimplantation. The high learning curve and technical difficulty needed for accurate intracorporeal suturing, however, have limited its widely adopted in clinical practice. Robotic platforms have since emerged as a promising alternative, offering enhanced dexterity and improved visualization, which facilitate complex suturing and achieve success rates comparable to open surgery. However, most available meta-analytical data are limited by high degrees of heterogeneity because previous studies have often combined laparoscopic and robotic procedures and have combined intravesical and extravesical reimplantation. This is a very general classification that can introduce systematic bias and mask underlying differences between modalities. Through this direct comparison of these two specific surgical approaches, the goal of this study is to isolate these variables to provide highly granular, clinically relevant evidence to inform surgical selection for modern practice. We conducted a comprehensive literature search across PubMed, Embase, Web of Science, and the Cochrane Library to identify clinical studies that directly compared the efficacy of RAUR via the extravesical approach with OUR for the treatment of VUR in pediatric patients. For the OUR group, no restriction was placed on the surgical approach, and both extravesical and intravesical techniques were included. The operative time, hospital stay, success rates, and postoperative complications such as urinary tract infection, urinary retention, and other complications were extracted for comparative analysis. A total of 473 patients from seven studies were analyzed. The results of the meta-analysis showed that there was no significant difference between the two groups in terms of total complications, but the RAUR group had significantly longer operative time (WMD&#x2009;=&#x2009;48.1 min, 95% CI [27.43, 68.76], p&#x2009;&lt;&#x2009;0.05) and significantly shorter length of hospitalization (WMD = -0.54 days, 95% CI [-0.96, -0.13], p&#x2009;&lt;&#x2009;0.05) when compared with the OUR group. When assessing surgical success rate, postoperative urinary tract infection, postoperative urinary retention, or overall complications, no significant differences were recorded between the two groups. In summary, these preliminary findings indicate that RAUR is associated with significantly longer operative time, which should be interpreted in the context of the learning curve. Although RAUR showed a statistically shorter hospital stay, the clinical benefit may be limited as most patients were discharged after overnight observation. Success and complication rates, including urinary tract infection and retention, were comparable to OUR, supporting the safety and efficacy of the robotic platform. Given equivalent key outcomes and expected experience accumulation, RAUR may be a viable alternative to OUR.

The protocol was retrospectively registered in PROSPERO (CRD420251075296). Comparative randomized and observational studies of elective robotic versus laparoscopic inguinal hernia repair in adults were eligible. Random-effects meta-analyses used restricted maximum-likelihood estimation with Hartung-Knapp confidence intervals; risk of bias was assessed using RoB 2 and MINORS, and certainty was evaluated using GRADE. Nineteen reports representing 18 unique cohorts and 78,940 participants were included. Nine reports (3,200 participants) contributed recurrence data; robotic repair was associated with a lower observed recurrence risk (RR 0.32, 95% CI 0.17-0.59; I 2 &#x2009;=&#x2009;0%), although certainty was low and the randomized evidence was imprecise. Robotic repair required longer operative time (11 studies; MD&#x2009;+&#x2009;30.04 min, 95% CI 9.87-50.20; I 2 &#x2009;=&#x2009;99.6%); after excluding the influential Holleran 2022 cohort, the estimate was&#x2009;+&#x2009;22.09 min (95% CI 8.87-35.30). Pooled immediate and postoperative-day-1 pain estimates did not show a statistically significant difference. Length of stay was not significantly different in the primary analysis (MD&#x2009;+&#x2009;0.33 days, 95% CI -0.03 to 0.70), while an influence analysis suggested a small increase after robotic repair (+&#x2009;0.18 days). Overall complication estimates were unstable, and no clear differences were found for hematoma, surgical-site infection, or urinary retention. Robotic repair was consistently more expensive across heterogeneous healthcare settings. Robotic inguinal hernia repair was associated with lower observed recurrence in predominantly non-randomized evidence, but this finding should not be interpreted as proof of causal superiority. Robotic repair generally required approximately 22-30 additional operative minutes and incurred higher costs, while pooled pain, length-of-stay, and complication findings were uncertain or clinically small. Technique selection should therefore consider patient and hernia characteristics, surgeon experience, institutional resources, and the low to very low certainty of the available evidence.","url":"https://pubmed.ncbi.nlm.nih.gov/42541618/","authors":["Alraddadi SE","Almeghthawi AH","Alahmadi HN","Aljahani AS","Aljohani JA","Aljohani NA","Alali RW","Alrashedi RR","Albalawi SA","Almakky MG"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Aug 1","addedAt":"2026-08-06T15:53:30.373Z"},{"id":"pmid:42541518","name":"Robotic-assisted pulmonary resection with a periareolar assistant port: learning curve and propensity-matched comparison with the conventional-portal approach.","source":"pubmed","abstract":"Periareolar incisions improve cosmesis in video-assisted thoracoscopic surgery, but their use as an assistant port in robotic-assisted thoracoscopic surgery (RATS) has not been formally described.

However, a range of biomedical applications require higher accuracies. Current multi-view tools either lack sufficient accuracy to justify the added burden of camera calibration or require higher-density multi-camera setups that discourage adoption in out-of-laboratory settings.

Trained on large synthetic data, DeepGaitLab overcomes the accuracy and generalizability constraints of current tools relying on real data. It outperforms both commercial and open-source alternatives and exhibits monotonic accuracy improvement with additional cameras. Unlike existing systems, its accuracy does not degrade when applied to individuals with mobility limitations. We evaluated DeepGaitLab in 80 individuals, including healthy adults, individuals recovering from anterior cruciate ligament reconstruction, individuals recovering from stroke, and ones with mild cognitive impairment, captured in two distinct environments. In addition to outperforming existing tools and demonstrating utility across three clinically distinct populations, DeepGaitLab offers the optional feature to enhance accuracy via an environment-specific fine-tuning strategy without requiring new labeled data.

The present study was designed to assess the global research status, knowledge structure, and evolving hotspots in the field of robot-assisted distal pancreatectomy through bibliometric and visualization analysis. A total of 254 eligible publications indexed in the Web of Science Core Collection between January 1, 2007 and December 31, 2025, including 210 articles and 44 reviews, were analyzed using Bibliometrix, VOSviewer, CiteSpace, and Scimago Graphica. The yearly publication output demonstrated a general increasing pattern, with more marked growth from the mid-2010s onward and the highest output recorded in 2025. Italy together with the United States remained the principal contributors across much of the study period, while China showed sustained growth in recent years. The United States ranked first in citation impact. Several institutions, including the University of Amsterdam, University of Verona, and University of Pisa, emerged as major contributors. Among the leading publication venues were Surgical Endoscopy and Other Interventional Techniques, Annals of Surgical Oncology, and Journal of Robotic Surgery. Citation and co-citation analyses showed that the intellectual structure of the field has been shaped mainly by studies focusing on surgical technique, perioperative outcomes, and comparisons with laparoscopic distal pancreatectomy. Keyword analysis indicated that spleen preservation, pancreatic fistula, laparoscopic comparison, learning curve, clinical outcomes, and multicenter evaluation are among the main research themes, with recent attention increasingly directed toward preservation strategies, outcome assessment, and more refined clinical application.

This structured review, conducted according to PRISMA guidelines across PubMed, Embase, and Web of Science, evaluates the clinical integration of AI-driven reconstruction, biomechanical modeling, and prognostic algorithms. The results indicate that AI-driven workflows significantly enhance surgical precision; convolutional neural networks demonstrated mean absolute errors of less than 1.2&#xa0;mm in landmark detection, while three-dimensional reconstructions achieved high anatomical fidelity with mechanical axis deviations averaging 0.52&#xb0;&#xb1;0.31&#xb0;.

To this end, MENPs comprising a cobalt ferrite magnetostrictive core and a piezoelectric barium titanate shell were fabricated.

The ability of MENPs to modulate cortical network activity in spontaneously rhythmic cortical slices under low-intensity static magnetic fields was tested. Using electrophysiological recordings, network activity was directly measured before, during, and after stimulation. Magnetic fields alone did not alter neuronal activity at the intensities used. In contrast, in the presence of MENPs, the same fields activated the network, enhancing the frequency of spontaneous rhythmic activity and thus network excitability. These findings demonstrate that MENPs lower the threshold for magnetic neuromodulation, providing a mechanistic link between weak magnetic inputs and network-level brain activity.

Validation experiments on Multi Vehicle Stereo Event Camera (MVSEC) dataset demonstrate strong performance: our method achieves 0.67 EPE averaged across all sequences, surpassing E-RAFT (0.89 EPE) and EV-FlowNet (1.10 EPE), without any additional data. On the rotation-heavy indoor_flying3 sequence specifically, we achieve 0.93 EPE (fine-tuned) and 1.49 EPE (self-supervised only) vs. E-RAFT 1.66. We also improve upon E-RAFT in computational efficiency [55 frames per second (FPS) and 26 giga floating-point operations (GFLOPs) vs. 42 FPS and 38 GFLOPs], while requiring only minimal supervised fine-tuning.","url":"https://pubmed.ncbi.nlm.nih.gov/42534837/","authors":["Feng A","Wenyin T"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","addedAt":"2026-08-06T15:53:30.373Z"},{"id":"pmid:42533186","name":"Robotic ultrasound scanning platform with autonomous control, multimodal human-machine interface and real-time image analysis.","source":"pubmed","abstract":"Autonomous robots can streamline repetitive and time-consuming surgical tasks like ultrasound scanning.

We frame the next phase of the field around three interdependent requirements: scalability, generalizability and provenance-complete experimentation. Realizing collective scientific superintelligence will require SDLs that reliably scale throughput, transfer workflows and learned models across laboratories and scientific domains and capture end-to-end experimental data and metadata from precursor preparation through synthesis, characterization and performance evaluation. Achieving this transition will depend on interoperable data and metadata standards, modular and integrable experimental hardware, and trustworthy artificial intelligence agents that reason under

the robot joint for the safety and flexibility of physical human–robot interaction. Design/methodology/approach A force sensing mechanism (FSM) for an S-shaped spring of a robot variable stiffness actuator (VSA) was designed. The yield strength of the spring material, geometric and assembly structure constraints of the VSA are all considered for the actuator deflection limit design. The elastic deformation model is solved in reverse to obtain the local deformation limit profile of the S-spring at different spring angles. The deformation limit mechanism is manufactured by three-dimensional printing and assembled with S-springs. The force sensing function for the VSA is achieved by the input and output shaft encoders and stiffness model. The FSM is verified by torque-deflection experiments with variable stiffness. Findings The yield strength of the S-spring material is the strictest constraint for elastic deformation. Experimental results show that the external force can be quickly and reliably perceived. As the spring angle increases (stiffness increases), the hysteresis and nonlinear error decrease. Under the constraint of the FSM, the maximum deflection also decreases rapidly. Originality/value The designed FSM based on the deformation and stiffness model provides a comprehensive design reference in a VSA with nonlinear elastic mechanisms, which is ignored but important for exploring the VSAs potential.","url":"https://doi.org/10.1108/ir-08-2024-0388","authors":["Yapeng Xu","Tongshuai Xin","Kai Guo","Jun Ma","Yang Cao","Xiaoke Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-05T04:21:21Z","doi":"10.1108/ir-08-2024-0388","addedAt":"2026-08-31T06:34:11.957Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.3390/biomimetics10060365","name":"Development of an Oblique Cone Dielectric Elastomer Actuator Module-Connected Vertebrate Fish Robot","source":"europepmc","abstract":"As a soft actuator for fish robots, an oblique cone dielectric elastomer actuator (DEA) module inspired by the structure of white muscles in fish was proposed in the authors’ previous study.

Therefore, disaster response robots are expected to reach disaster areas and operate at dangerous sites as quickly as possible. Humanoid robots are considered promising disaster response robots for performing various tasks instead of humans at disaster sites. To deploy robots at these sites, parachute descent is considered because the roads to reach the destination are generally destroyed. However, during parachute descent, the impact on the robot is quite significant compared to falling when standing or walking. To achieve parachute descent, it is necessary to generate an impact-absorbing landing motion. This paper develops a landing impact simulator to demonstrate the landing motion of a one-legged robot equipped with a series elastic actuator (SEA). The SEA features necessary characteristics to reduce impact while executing appropriate motion. First, the impact on a one-legged robot during landing was analyzed using a drop test. Second, based on the assumption of the linear spring-damper model of the SEA, the model parameters, such as the spring and damping coefficients, were identified through an optimization method using the results of the impact experiment. Subsequently, a landing impact simulation of the robot was performed to evaluate the validity of the developed SEA model. Compared with the drop test of a one-legged robot, it is confirmed that the developed SEA model has sufficient performance to reproduce the behavior of the flexible joint during landing.","url":"https://doi.org/10.20965/jrm.2025.p0627","authors":["Tomoharu Sekine","Satoko Abiko","Teppei Tsujita"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-19T11:02:08Z","doi":"10.20965/jrm.2025.p0627","addedAt":"2026-08-31T06:34:11.957Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/citsc64390.2025.00102","name":"Design and Control of a Flexible Actuator Joint for Lower Limb Exoskeleton Robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/citsc64390.2025.00102","authors":["Yapeng Wang","Yunhai Geng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-03-28T03:18:58Z","doi":"10.1109/citsc64390.2025.00102","addedAt":"2026-08-31T06:34:11.957Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.2139/ssrn.5122837","name":"The Bi-Directional Motion Behavior Of the Vibration-Driven Locomotion Robot Excited by A Dielectric Elastomer Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5122837","authors":["Lili Meng","Xiaojian Wang","Shaochong Zhang","Fucai Li","Hongguang Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-03T17:43:54Z","doi":"10.2139/ssrn.5122837","addedAt":"2026-08-31T06:34:11.957Z","updatedAt":"2026-08-31T06:34:16.555Z"},{"id":"doi:10.1007/s10958-025-08091-7","name":"IMPLEMENTATION OF SERVO-CONSTRAINTS IN PROBLEM OF CONTROLLING SPHERICAL ROBOT WITH PENDULUM ACTUATOR","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s10958-025-08091-7","authors":["E.

In addition, for pneumatically controlled actuators, multiplexing is essential to reduce the tubing from the control valves. A miniaturized soft pneumatic actuator matrix (SPAM) with multiplexing control of crossing points by only control signals was realized by embedding two layers of interactive channels () in a soft material (PDMS) to form actuators () by cumulating both strokes and forces at the channel crossings, unlike piston‐based serially coupled gas‐springs that yield constant force.

During actuation, the soft robotic exo-digit interacted with a sensor-integrated human finger model, and its morphology deformed under applied pressure. A physical reservoir framework was developed to harness this morphological information for predicting contact forces, joint bending angles, and joint torsional stiffness. The soft actuator segment served as the physical reservoir and was connected to three separate linear readouts, each dedicated to predicting a specific parameter. The experimental setup included three different soft actuator attached to the corresponding 3D-printed anthropomorphic joints with embedded torsional springs. A motion-capture camera and integrated sensors (FlexiForce and IMU) measured contact forces and joint motion. The actuator’s deformation was tracked using image processing based on marker positions and sensors captured joint angles and contact forces. Experimental results validated the effectiveness of the learning framework, demonstrating accurate estimation of the targeted force and motion parameters.","url":"https://doi.org/10.1115/smasis2025-167880","authors":["Umme Kawsar Alam","Mahdi

provide improved control, safety, energy efficiency, and performance compared to traditional rigid actuators, making them well-suited for various applications in robotics, rehabilitation, and human-robot interaction. However, the inherent flexibility of SEAs can lead to oscillations in the position of SEA robots. This paper introduces a radial basis function (RBF) neural network-based adaptive super-twisting sliding mode control approach for position tracking of SEA robots. The robust control part of the proposed strategy, the super-twisting sliding mode control, effectively provides stability and robustness, demonstrates finite-time convergence, and suppresses oscillations caused by the joints. Beyond implementing robust control, the Radial Basis Function (RBF) neural network coordination is crucial for effectively approximating the unknown components of the manipulator dynamical model and uncertainties encountered in practical applications. The unknown nonlinearities are approximated through an RBF neural network, wherein the network's weight parameters are dynamically adjusted in real-time based on adaptive laws. Leveraging the RBF model, an adaptive control algorithm is formulated via the Lyapunov synthesis approach. Simulation outcomes corroborate the efficacy of the proposed controller in attaining accurate position tracking while effectively reducing oscillations.

However, the complex preparation processes, high costs, poor convenience, complex structures, and low sensitivity, restricting their further application. In this work, we propose a double‐layer flexible photo‐driven composite film of graphene oxide‐carbon nanotube‐polydimethylsiloxane/polyethylene (GO‐CNT‐PDMS/PE), which has achieved the efficient conversion of GO‐CNT‐PDMS/PE photo‐driven films from photo energy to thermal energy and then to mechanical energy. The COMSOL finite element simulation model is established and simulated. A two‐stage conversion model of “photo‐heat‐mechanical energy” is proposed to verify the thermal response of the material and the photo‐driven mechanism. The influence of different thicknesses of photothermal layers (GO‐CNT‐PDMS) and GO‐CNT concentrations on the performance of double‐layer flexible optical drivers are studied. Based on the optimized GO‐CNT‐PDMS/PE flexible photo‐driven composite film, the designed near‐infrared photo‐driven flexible soft robots grippers have achieved photo‐controlled bending deformation and successfully grasped the target object. The feasibility of it in micro‐nano operation scenarios is verified by adjusting the light intensity and duration, controlling the opening and closing angle of the gripper and the grasping force.

This innovative actuator configuration is inspired by the tail structure of Body and/or Caudal Fin (BCF) mode fish. The actuator's motion is achieved by controlling the expansion and contraction of the pneumatic soft muscles on both sides. And by constructing an experimental platform, we conducted an in-depth performance characterization, revealing the existence of a frequency-dependent nonlinear hysteresis characteristic of the FPSA. In order to accurately characterize this property, we built a dynamic model of the FPSA and successfully identified the uncertain parameters in the model by applying the nonlinear least squares method. The validation results show that the constructed model can accurately describe the nonlinear hysteresis characteristics of the FPSA.

First, the model of the propeller‐driven wall‐climbing robot is established, where actuator dynamics and input saturation are considered with velocity constraints. The strategy of active gravity balance is put forward, which simplifies the modeling but leads to the problem of velocity‐related input saturation. Second, the Gauss integration function is used to approximate the velocity‐related input saturation. The velocity constraint would be handled by employing the barrier Lyapunov‐based transformation rather than the barrier Lyapunov function (BLF) method. Thirdly, the tracking controller is developed based on the dynamic surface control method, where the adaptive robust controller and neural networks are combined to deal with unmodeled dynamics and external disturbances. According to the Lyapunov stability theory, it is proved that the propeller‐driven robot system will be stable under the developed controller, while signals in the closed‐loop system are ultimately uniformly bounded.

Here, a centimeter‐scale jumping biomimetic water strider robot (mass: 0.21 g) that uses surface tension to jump on the water surface is presented. The robot employs an electro‐ribbon actuator, enabling sub‐second kinetics response, achieving vertical leaps of 128 mm with minimal surface perturbation. The gravitational potential energy of the robot at peak jumping height exceeds several orders of magnitude compared to the existing surface tension‐dominated jumping robot. Additionally, the study also systematically studies the interaction mechanism of dynamic contact between the robot's driving legs and the liquid‐air interface.

Herein, the dual actuator wave‐like navigator (DAWN), a multisurface robot employing two actuated helical wave generators to produce continuous traveling waves on flexible link tracks enclosed in elastomer skins, is presented. These skins provide mechanical resilience, enhanced friction, and adaptability on uneven terrain. The robot demonstrates steering and controlled locomotion on flat surfaces, inclines, and declines. To characterize the robot, locomotion tests are performed on plywood, PMMA, and sand, achieving average linear speeds of 16.00, 15.76, and 1.63 mm s −1 , respectively. A key innovation is cyclic pneumatic actuation of the skins with actuation frequencies of 0.5 and 0.9 Hz, improving locomotion performance on sand to 2.22 and 2.70 mm s −1 . DAWN's capability to move on sand, grass, gravel, and wet soil is also demonstrated. Its modular design enables plug‐and‐play assembly of components including helical wave generators, flexible link tracks, and elastomer skins, allowing for easy maintenance, modification, and replacements. Potential applications include navigation in complex terrains for search and rescue, inspection, and environmental monitoring.","url":"https://doi.org/10.1002/aisy.202500422","authors":["Mathias Jensen","Magnus Malthe Sigsgaard Nielsen","Nicklas Nikolaj Grønvall","Jonathan Tirado","Jonas Jørgensen","Saravana Prashanth Murali Babu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-08-20T16:41:12Z","doi":"10.1002/aisy.202500422","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:11.958Z"},{"id":"doi:10.1109/icmech.2013.6519119","name":"A new asymptotic tracking approach for robot manipulators with actuator saturation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icmech.2013.6519119","authors":["Yuxin Su","J.

Traditionally, its primary goal was minimizing interaction forces during assistance. However, under this conventional definition, mechanical transparency was not considered when an interaction force was required during assistance. This research focuses on achieving mechanical transparency within the context of shoulder motion in upper extremity exoskeletons for rehabilitation. Our primary goal is maintaining interaction forces at target values, even with motion disturbances. To this end, we developed a shoulder actuation testbed for exoskeletons, incorporating a fusion hybrid linear actuator distinguished by high back-drivability, robust torque generation capability, and safety features. To attain mechanical transparency, we created a model for calculating the required joint torque, accounting for gravitational dynamics, and subsequently determined the necessary actuator output. The system characteristics were evaluated based on the joint torque generated by the actuator. The actuator utilized pneumatic pressure to generate force and compensated for kinetic friction using electromagnetic forces. The results showed that the compensation by the electromagnetic force reduced the root mean square error of the torque to less than 60% in relation to pneumatic pressure alone. This demonstrated the ability to generate consistent torque with high robustness to motion disturbances.","url":"https://doi.org/10.36227/techrxiv.171591369.97493239/v2","authors":["Takuma Shimoyama","Tomoyuki Noda","Tatsuya Teramae","Yoshihiro Nakata"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-30T13:30:07Z","doi":"10.36227/techrxiv.171591369.97493239/v2","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/tia.2025.3532577","name":"Quadruped Robot Calf Joint Actuator Molding and Design Based on Dynamic Similarity Hypothesis","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tia.2025.3532577","authors":["Guanbao Zeng","Lijian Wu","Yu Haoyong","Dianhe Zhao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-01-21T18:25:31Z","doi":"10.1109/tia.2025.3532577","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:11.958Z"},{"id":"doi:10.37965/jdmd.2025.690","name":"Actuator Fault Diagnosis of 3-PR (P) S Parallel Robot Based on DBO-BP Neural Network","source":"crossref","abstract":"Any malfunctions of the actuators of the robots have the potential to destroy the robot's normal motion，and most of the current actuator fault diagnosis methods are difficult to meet the requirements of simplifying the actuator modeling and solving the difficulty of fault data collection. To solve the problem of real-time diagnosis of actuator faults in the 3-PR(P)S parallel robot, the model of 3-PR(P)S parallel robot and data-driven-based method for the fault diagnosis is presented. Firstly, only the input-output relationship of the actuator is considered for modelling actuator faults, reducing the complexity of fault modelling and reduces the time consumption of parameter identification, thereby meeting the requirements of real-time diagnosis. A Simulink model of the electromechanical actuator (EMA) was constructed to analyze actuator faults. Then the Short-term analysis method is employed for collecting the sample data of the slider position on the test platform of the EMA system and feature extraction. Training samples for neural networks are obtained. Furthermore, we optimized the Back Propagation (BP) neural network using the Dung Beetle Optimization Algorithm (DBO), which effectively resolved the weights and thresholds of the BP neural network. Compared to BP and PSO-BP, the DBO-BP has better convergence, convergence rate, and the best-classifying quality. So, the classification for the different actuator faults is obviously improved. Finally, a fault diagnosis system was designed for the actuator of the 3-PR(P)S parallel robot, and the experimental results demonstrate that this system can detect actuator faults within 0.1 seconds. This work also provides the technical support for the fault-tolerant control of the 3-PR(P)S Parallel robot.

However, implementing an emergency procedure for these manipulators is not trivial, since stopping the actuators abruptly does not imply that the end-effector rests at a stable position. This paper improves a previous recovery strategy by introducing the physics of the actuators, i.e., torque limits, inertia, and friction. Such features deeply affect the reachable acceleration during the recovery trajectory. The strategy has been applied to a simulated point-mass suspended cable robot with three translational degrees of freedom to prove its effectiveness and feasibility. The acceleration limits during the recovery phase were compared with the ones obtained with the previous method, thus confirming the necessity of contemplating the properties of the actuators. The proposed strategy can be implemented in a real-time environment, which makes it suitable for immediate application to an industrial environment.","url":"https://doi.org/10.3390/app10207362","authors":["Giovanni Boschetti","Riccardo Minto","Alberto Trevisani"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-10-21T10:14:22Z","doi":"10.3390/app10207362","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/iciea.2018.8397764","name":"A new adaptive controller for robot manipulators considering actuator dynamics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iciea.2018.8397764","authors":["An-Chyau Huang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-06-28T18:35:04Z","doi":"10.1109/iciea.2018.8397764","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.17958/ksmt.12.2.201006.67","name":"Development of Robot Actuator Mechanism with Slider Joint","source":"crossref","abstract":"","url":"https://doi.org/10.17958/ksmt.12.2.201006.67","authors":["이종신"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-04-02T16:16:58Z","doi":"10.17958/ksmt.12.2.201006.67","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/icra.2014.6907290","name":"Fast dynamic optimization of robot paths under actuator limits and frictional contact","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2014.6907290","authors":["Kris Hauser"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-09-30T16:32:36Z","doi":"10.1109/icra.2014.6907290","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1017/s0263574700017719","name":"A high torque to weight ratio robot actuator","source":"crossref","abstract":"Summary A light-weight, high-torque actuator with accurate torque control capability is described. The actuator uses a small hydrostatic transmission to achieve the advantage of large gear reduction from a high speed DC motor, and retains accurate joint torque sensing and control capabilities with no backlash. A disadvantage of the actuator is that is introduces extra dynamics which must be accounted for in robot control systems. It is shown that state feedback enables closed loop control of joint torque, with full back drivability, through an effective gear ratio of 485:1 for the experimental system. The actuator can therefore be used for both position control and output force control, which is essential for modern robot control algorithms. A mathematical model of the system is presented in this paper along with experimental results.","url":"https://doi.org/10.1017/s0263574700017719","authors":["James E.

The robot should have the ability to pull lead cables over cable racks and ceiling spaces. Therefore, we propose a reconfigured active-cord-mechanism robot based on the RSAW mechanism that can move in both environments by maintaining continuous traveling wave propagation across multiple units connected through joints. A prototype robot was first constructed to verify the applicability of the RSAW mechanism to cable-laying environments. However, the discontinuity of the traveling wave at the joint connections prevented the prototype from traversing ceiling spaces. Based on this finding, a new robot was developed with a configuration that ensures continuous wave propagation across the joints through mechanical design and phase synchronization control. As a result, the new robot enhances propulsion speed and cable traction. Additionally, the robot can move over ceiling joint receivers that exist in ceiling spaces. Comparative analysis with previous prototype robots and a snake-like robot highlights this robot’s advantages, including reduced motor count, autonomous operation with mounted power and control units, and superior turning capabilities.","url":"https://doi.org/10.3390/machines14050521","authors":["Fuga Inagaki","Yuki Sadasue","Masami Iwase"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-08T20:11:13Z","doi":"10.3390/machines14050521","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1109/ccdc.2018.8407607","name":"State feedback finite-time tracking controller of nonholonomic mobile robot with actuator delay","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ccdc.2018.8407607","authors":["Qingyu Xue","Xin Yu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-07-30T18:38:13Z","doi":"10.1109/ccdc.2018.8407607","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/aim55361.2024.10637046","name":"A low backlash and highly efficient gearbox for robot actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim55361.2024.10637046","authors":["Wonseok Shin","Bummo Ahn","Suncheol Kwon"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-22T17:52:35Z","doi":"10.1109/aim55361.2024.10637046","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1115/1.4065091","name":"Helical Actuator–Driven Inchworm Robot Design and Prototype","source":"crossref","abstract":"Abstract Bio-inspired robots provide solutions in many applications. Robots that can traverse and transport materials through confined areas are useful in disaster response, mining, mapping, and tunneling. The proposed robot is an inchworm-inspired robot that contracts and expands its body segments to move. It has spiky feet that are angled to only allow each foot to slide forward. It has a small frontal area compared to its length, and this allows it to travel through tight gaps or tunnels. Each segment uses two helical actuators as prismatic linkages to drive both forward movement and turning movement. These helical actuators transform the rotation of stepper motors into linear motion. Many linkage configurations were considered in designing this robot, and one without continuous singularities was selected. The robot stride consists of an extension phase and a contraction phase. In each phase, one foot is stationary, and one foot is moving. When each of the feet is in motion, the ground reaction force is assumed to be zero. The motion planning of the robot is designed so that the velocity and acceleration of each of the robot's rigid bodies are zero at the beginning and end of each movement phase. A 3D-printed prototype of the robot has been manufactured, and initial testing has shown that the foot spike design successfully allows the inchworm to shuffle forward. Testing the turning capabilities of this robot is ongoing.","url":"https://doi.org/10.1115/1.4065091","authors":["Joel Quarnstrom","Yujiang Xiang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-03-18T16:29:25Z","doi":"10.1115/1.4065091","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/mecatronics.2014.7018558","name":"New linear solenoid actuator for humanoid robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mecatronics.2014.7018558","authors":["S.

The soft actuators developed thus far include those that can extend or bend by only supplying compressed air, or those that switch their motions by modifying their structures. However, the type of motion is limited and structural modifications are required to switch between different movements. In this study, we developed a soft actuator with multiple degrees of freedom that allowed switching between extension and bending without structural changes. This actuator comprised a structure in which flexible linear brakes (FLBs), which are negative-pressure-driven linear braking mechanisms, were arranged alongside a bellows-structured silicone rubber tube (bellows tube). The bellows tube extended when compressed air was supplied. When engaged, the FLBs provided fiber reinforcement against the bellows tube and bent the actuator. Thus, the actuator switched between extension and bending by engaging or disengaging the FLBs without structural changes. In this paper, we describe the structure of the actuator and the mechanical model used to arbitrarily change its bending direction using braking mechanisms.","url":"https://doi.org/10.20965/jrm.2025.p0162","authors":["Taiki Tsuji","Daisuke Sasaki","Jun Kadowaki","Hayato Yase","Kaisei Harada"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-19T15:02:07Z","doi":"10.20965/jrm.2025.p0162","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:11.958Z"},{"id":"doi:10.1109/robot.2005.1570304","name":"Multi-Axis SMA Actuator Array for Driving Anthropomorphic Robot Hand","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.2005.1570304","authors":["Kyu-Jin Cho","H.

Inspired by the body forms of adult cnidaria, we developed a morphing mechanism that serves as both structure and actuator for the Soromone's behavior using a soft tectonics approach-a multistep, multiscale, heterogeneous soft material fabrication technique. As an actuator, the morphing mechanism can precisely control the Soromone via a fluid system; as a structure, it can reinstate the Soromone's original shape by incorporating various degrees of stiffness or softness into a single piece of material during fabrication. Our study demonstrates the advantages of applying a Soromone under water, including increasing water flow for enhanced nutrient uptake, waste removal, and gas exchange.

Furthermore, the work successfully utilizes granular Resistive Force Theory (RFT) as a reduced-order model, demonstrating how theoretical physics can directly validate bio-inspired mechanical design.The concept of maximizing anisotropy is then elegantly distilled in \"Efficient reciprocating burrowing with anisotropic origami feet\" (Kim et al., 2023). This paper presents a beautiful, minimalist solution to the locomotion and anchoring problems. Instead of relying on complex, multi-actuator systems, the design uses foldable origami feet that passively induce the necessary anisotropic friction. With a single actuator applying only symmetric linear motion, the robot achieves highly efficient, directed burrowing, validating the power of leveraging smart material mechanics-a key theme from the review papers-to achieve complexity of motion with simplicity of actuation.The narrative culminates by applying these concepts to one of the most extreme environments: submerged granular media. \"Burrowing and unburrowing in submerged granular media through fluidization and shapechange\" (Nayak et al., 2025) presents a system that addresses the double challenge of both sinking and rising. Drawing inspiration from the razor clam's brilliant strategy, the robotic system employs water-jetbased fluidization for its descent, drastically reducing drag. For the crucial, often-neglected problem of unburrowing (rising), the robot utilizes an untethered, soft, inflatable bladder that undergoes periodic radial expansion, a direct parallel to the soft-robot principles of anchoring and shape-morphing. This work is groundbreaking for applications in marine research, archaeology, and seabed infrastructure.This collection clearly demonstrates that the future of subterranean robotics lies in the symbiotic intersection of biology, material science, and engineering mechanics. These five papers take us from defining the four fundamental challenges and identifying the grand challenges of soft materials to creating specific, highly efficient hardware solutions that leverage anisotropic forces in granular media and fluidization in underwater environments.

SBUVs are characterized by bodies made of flexible and extensible materials, integrating the dual advantages of softness and biomimetics. They can achieve muscle-like continuous deformation to efficiently absorb collision energy, while mimicking the propulsion mechanisms of marine organisms-such as fish and jellyfish-through undulating body movements or cavity contraction and relaxation. Such biomimetic propulsion is highly compatible with the flexible actuation of soft materials, enabling excellent environmental adaptability while maintaining favorable propulsion efficiency. Compared with traditional rigid underwater vehicles, SBUVs offer higher degrees of freedom, superior environmental adaptability, enhanced impact resistance and greater motion flexibility. This review systematically summarizes typical actuation methods for SBUVs-including fluid-powered actuation, shape memory alloy actuation, and electroactive polymer actuation-elaborating on their working principles, key technological advances, and representative application cases on SBUVs. These actuation mechanisms each offer distinct advantages. Fluid-powered systems are valued for high power density and precise motion control through direct fluidic force transmission. Shape memory alloys provide high force output and accurate positional recovery via controlled thermal phase changes. Meanwhile, electroactive polymers stand out for their rapid (often millisecond-scale) dynamic response, low hysteresis, and fine, muscle-like deformation under electrical stimuli. Current challenges are also analyzed, such as limited actuation efficiency, material durability issues, and system integration difficulties. Despite these constraints, SBUVs show broad application prospects in marine resource exploration, ecological monitoring, and underwater engineering operations. Future research should prioritize the development of novel materials, coordinated optimization of actuation and control systems, and breakthroughs in core technologies to accelerate the practical implementation and industrialization of SBUVs.","url":"https://doi.org/10.3390/mi17020258","authors":["Liu X","Li J","Xing Y","Zhang Z","Cao Y","Li B"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/mi17020258","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:36.400Z"},{"id":"doi:10.1109/tmech.2025.3602061","name":"Compact Design and Image-Space Pose Control of a Robot for Tendon-Driven Concentric Catheters in Mitral Repair Interventions.","source":"europepmc","abstract":"","url":"https://doi.org/10.1109/tmech.2025.3602061","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1109/tmech.2025.3602061","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:19.809Z"},{"id":"doi:10.1126/sciadv.adz2928","name":"Multimaterial 3D printed soft robots with embedded actuation and sensing.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.adz2928","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1126/sciadv.adz2928","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1007/s10143-025-03976-2","name":"Curved trajectories in stereotactic neurosurgery: is it feasible?","source":"europepmc","abstract":"","url":"https://doi.org/10.1007/s10143-025-03976-2","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1007/s10143-025-03976-2","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics11050317","name":"Residual Stress-Based Soft Robot with Capability for Grasping and Buoyancy Control.","source":"europepmc","abstract":"Underwater soft robots offer many potential applications, including exploration, search, and rescue missions.

Modulating the volume of internal fluid can function both as a gripper and adjust buoyancy as needed. When buoyancy is reduced and fluid volume is minimized, the gripper can securely grasp objects, while increased fluid volume and buoyancy allow for delicate object placement.

vibration suppression of a tendon-driven soft robotic neck for the social robot HARU.","source":"pubmed","abstract":"Tendon-driven continuum actuators (TDCAs) provide compliant and lifelike motion that is well suited for human-robot interaction, but their structural compliance and underactuation make them susceptible to undesired vibrations, particularly along unactuated axes under load. This work addresses vibration suppression in such systems by proposing a real-time control strategy for a two-degree-of-freedom TDCA-based soft robotic neck used in the HARU social robot, where yaw motion is unactuated and prone to oscillations due to eccentric loading. The proposed approach combines a current-based tendon pretensioning routine, baseline PID control of the actuated pitch and roll axes, and a novel Coupled Axis Indirect Vibration Suppression (CIVS) mechanism. CIVS exploits mechanical cross-axis coupling by using high-pass filtered yaw acceleration from an inertial sensor to generate transient tension modulations in the actuated tendons, thereby increasing effective damping of the unactuated yaw mode without introducing additional hardware or compromising compliance. A classical sliding mode control is also implemented as a nonlinear benchmark under identical hardware constraints. Experimental validation on the HARU neck under representative loading conditions demonstrates that the proposed method achieves substantial vibration attenuation. Compared to the baseline controller, CIVS reduces yaw angular range by approximately 53% and yaw acceleration area by over 60%, while preserving smooth, expressive motion. The results further show that CIVS outperforms the sliding mode controller in suppressing vibrations on the unactuated axis. These findings indicate that indirect, feedback-driven tendon modulation provides an effective and low-complexity solution for mitigating load-induced vibrations in underactuated soft robotic systems, making the approach particularly suitable for interactive applications where safety, compliance, and motion expressivity are critical.","url":"https://doi.org/10.3389/frobt.2025.1698343","authors":["Thorapalli Muralidharan S","Gomez R","Andrikopoulos

Muscles: Electrostatic Actuation and Design Tradeoffs.","source":"europepmc","abstract":"Artificial muscles are an emerging class of actuators designed to mimic the compliant, efficient, and versatile behavior of biological muscles for fields including the following: soft robotics, prosthetics, wearable enhancements, haptic interfaces, and biomedical devices. These systems encompass various actuation mechanisms, including pneumatic, hydraulic, thermal, ionic, electrochemical, and electrostatic. Each with distinct tradeoffs in voltage, strain, output force, bandwidth, efficiency, and manufacturability. Among them, electrostatic actuators have attracted increased attention due to their fast response times, high energy densities, strong compatibility with soft materials, and scalability from microscale devices to large-area and stacked actuators. However, challenges such as dielectric breakdown, material fatigue, and fabrication complexity continue to limit widespread deployment. This review presents a structured classification of various artificial muscle technologies and an in-depth examination of electrostatic actuators including dielectric elastomers, electrostrictive and ferroelectric polymers, liquid crystal elastomers, electrostatic film motors, stacked architectures, and microscale/milliscale devices. In this review the operating principles, materials, architectures, performance characteristics, and failure modes of electrostatic actuators will be discussed. Additionally, a comparison will highlight tradeoffs across actuator families based on metrics such as voltage, force, strain, bandwidth, and manufacturability.

Inspired by the distal morphology of the African elephant trunk, we present MELEGROS, a Monolithic ELEphant-inspired GRipper with Optical Sensors, emphasizing sensing as an intrinsic, co-fabricated capability. Unlike multi-material or tendon-based approaches, MELEGROS directly integrates six optical waveguide sensors and five pneumatic chambers into a pneumatically actuated lattice structure (12.5 mm cell size) using a single soft resin and one continuous 3D print. This eliminates mechanical mismatches between sensors, actuators, and body, reducing model uncertainty and enabling simulation-guided sensor design and placement. Only four iterations were required to achieve the final prototype, which features a continuous structure capable of elongation, compression, and bending while decoupling tactile and proprioceptive signals. MELEGROS (132 g) lifts more than twice its weight, performs bioinspired actions such as pinching, scooping, and reaching, and delicately grasps fragile items like grapes. The integrated optical sensors provide distinct responses to touch, bending, and chamber deformation, enabling multifunctional perception. MELEGROS demonstrates a new paradigm for soft robotics where fully embedded sensing and continuous structures inherently support versatile, bioinspired manipulation.","url":"https://doi.org/10.1002/advs.202518878","authors":["Trunin P","Cafiso D","Nardin AB","Exley T","Beccai L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202518878","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/advs.202514807","name":"High-Speed, Maneuverable, and Terrain-Adaptive Micro-Robot with Tree Frog-Inspired Bionic Feet.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/advs.202514807","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202514807","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:19.810Z"},{"id":"doi:10.1038/s41378-026-01161-z","name":"Wire-form shape memory alloy actuators: modeling, design, and control.","source":"pubmed","abstract":"Wire-form shape memory alloy (WF-SMA) actuators have become integral components in numerous advanced applications ranging from robotics and aerospace to biomedicine thanks to their exceptional energy density, compact architectures and versatile actuation modes. Serving as a unique bridge between high-force actuation and material compliance, WF-SMAs enable the fabrication of intelligent soft materials and stretchable electronic systems. This work contributes a comprehensive and systematic assessment of WF-SMA actuators, including actuation modeling methodologies, typical actuator configurations, control strategies, and cutting edge applications in multiple fields. We firstly revisit the SMA actuation models with an emphasis on the theoretical foundation as well as current challenges in representing SMA's nonlinear, thermodynamic and actuation behaviors. Then, actuator design paradigms are classified according to the characteristic of the mechanical load (i.e. linear, nonlinear and differential) followed by briefly exploring the large-stroke strategies. Control approaches for manipulating WF-SMA systems are also surveyed covering a spectrum from conventional algorithms to smart strategies based on SMA-specific models, neural networks and integrated self-sensing methods. Drawing upon this assessment, we elucidate the key challenges that impede the widespread and practical application of SMA technologies, and suggest that future fabrication of WF-SMA actuators should increasingly rely on the integration of micro-nano fabrication techniques, flexible electronics, and multifunctional materials. Another promising direction for future research would be to prioritize the development of integrated modeling-design-control frameworks. Leveraging deep learning within the framework to navigate the complex nonlinearities of SMAs will directly improve operational performance and long-term reliability.","url":"https://doi.org/10.1038/s41378-026-01161-z","authors":["Zhang R","Yue H","Sun H","Wang M","Yang F","Liu J","Yu Z","Huang X","Rongru Zhang","Honghao Yue","Hao Sun","Miao Wang"],"tags":["Actuator","Shape-memory alloy","Aerospace","SMA*","Fabrication"],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41378-026-01161-z","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"doi:10.1038/s41467-025-63373-7","name":"Optimization and control of actuator networks in variable geometry truss systems using genetic algorithms.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-63373-7","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-63373-7","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3389/frobt.2026.1735467","name":"Calibration-free per-finger force-feedback slip control for grasping by anthropomorphic hand with tri-axial tactile sensors.","source":"pubmed","abstract":"This paper addresses the challenge of detecting and recovering from slip during robotic grasping of unknown objects, with the objective of establishing a robust no on-site or per-object calibration slip-recovery controller for an anthropomorphic hand. This hand is equipped with tri-axial piezoresistive tactile force sensors on each finger, and the proposed approach is validated through experimental analysis. The proposed methodology eliminates the need for object- or pose-specific calibration, explicit friction modelling, dense tactile arrays, line-of-sight vision, and a data-hungry learning process, enabling real-time implementation with minimal computation and integration effort. Using a commonly acquired online baseline from initial readings, slip is detected from relative changes between consecutive samples of the baseline-subtracted resultant tangential force, and object engagement is determined when the normal force reading deviates from a no-slip baseline beyond a preset threshold. Upon detecting slip, each finger increases its gripping force in closed-loop control until the slip stops, while enforcing motor-current protection in finger control to prevent actuator overload and object damage. Experiments were conducted on objects with different rigidity, weight, and surface textures, including an aluminium tube, a plastic water bottle, and a sponge. Additionally, the response time and variations in gripping force were evaluated. The results demonstrate rapid slip response via localized per-finger correction, good object conformability, and effective re-stabilization under different lifting speeds and sudden external disturbances. The per-finger design utilizes the minimum necessary correction at the offending finger, reducing unnecessary force increases on other fingers and improving grasp efficiency. This approach represents a practical solution for warehouse picking, human-robot collaboration, and in situ manipulation where task-specific calibrations, visual access, or training datasets are impractical.","url":"https://doi.org/10.3389/frobt.2026.1735467","authors":["Wong DCY","Zhu ZH"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1735467","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.3389/frobt.2025.1667688","name":"Design of modified fractional-order PID controller for lower limb rehabilitation exoskeleton robot based on an improved elk herd hybridized with grey wolf and multi-verse optimization algorithms.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1667688","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1667688","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1089/soro.2024.0157","name":"Bioinspired Design for Energy-Efficient Soft Actuators Achieving Asymmetrical Spatiotemporal Deformation.","source":"europepmc","abstract":"This article presents a bioinspired pneumatic soft actuator designed to achieve asymmetrical spatiotemporal deformations, inspired by the dynamic motion of human walking.

They are widely used in applications where human beings and robots interact closely, such as service robots or medical robots. However, PAMs are constrained by bulky pumps and valve control systems, limiting their mobility, portability, and practical applications. In this research, a novel type of artificial muscle, namely Twisting Tube Artificial Muscle (TTAM), is presented. In a TTAM design, fluid (pressurized air in this research) is contained inside an elastic tube (constrained by a braiding). By twisting the tube from one end, the fluid inside the twisted part will be extruded to the untwisted part, resulting in a pressure increase inside the untwisted part. Both the twisted and untwisted parts will thus contract. Modeling and experimental characterization of the TTAM are conducted. In an experimental test at 100 kPa initial air pressure, after a 6&#x3c0; twisting angle, the internal pressure of a prototype TTAM is increased to 219 kPa, and the largest contraction force of the TTAM was up to 200 N.

This mechanism may initially appear inefficient, since the contraction of a muscle group stretches the antagonist, increasing resistance and energy consumption. However, the hierarchical architecture of muscles provides a clever solution. By giving rise to J-shaped stress-strain responses, muscle tissue is soft at small strains, thus minimizing resistance, while it stiffens at large strains to enable economical energy release and prevent excessive elongation and damage. Here, we develop hierarchical supercoiled artificial muscles by plying fishing line fibers that recapitulate this behavior and thus allow antagonistic actuation. Computational models based on Cosserat rods reveal the physical mechanisms underlying the observed J-shaped responses. The artificial muscles are used in an antagonistic biceps/triceps arm mechanism and a vertical rope-climbing robot that weighs 14.4 grams and carries a payload 14.6 times heavier than its own&#xa0;weight.","url":"https://doi.org/10.1002/advs.202521604","authors":["Tsai S","Cheng L","Albazroun A","Wang Q","Kim J","Tekinalp A","Kim S","Simcox C","Downing R","Sivaramakrishnan V","Carsello G","Bimrose M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202521604","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:19.810Z"},{"id":"doi:10.1038/s41467-025-67936-6","name":"Magnetically actuated momentum-driven millirobots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-67936-6","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-67936-6","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41598-025-19449-x","name":"Hybrid integral sliding mode and fuzzy logic control for omnidirectional robots: modified elephant herding optimization for trajectory tracking.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-19449-x","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41598-025-19449-x","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3389/frobt.2026.1857985","name":"Passive wheels on legged robots: a survey.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1857985","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1857985","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.1002/smo2.70026","name":"Incorporating crystalline smart materials to fabricate 4D printed photomechanical actuators with photovoltaic performance.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/smo2.70026","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/smo2.70026","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:19.810Z"},{"id":"doi:10.3390/s25134016","name":"A Survey on Design and Control Methodologies of High- Torque-Density Joints for Compliant Lower-Limb Exoskeleton.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25134016","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25134016","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3389/frobt.2025.1753153","name":"Editorial: Wearables for human-robot interaction and collaboration.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1753153","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1753153","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3389/frobt.2026.1769141","name":"Fast adaptation of physics-informed hybrid models for pneumatic artificial muscles.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1769141","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1769141","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41467-025-59559-8","name":"Edible aquatic robots with Marangoni propulsion.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-59559-8","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-59559-8","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1126/sciadv.aed2847","name":"Bioinspired flow sensor enables underwater robots to estimate motion and detect flow structure.","source":"europepmc","abstract":"We address the challenge of sensing self-motion and environmental information by autonomous underwater vehicles.

To address the challenges, we present a small and lightweight soft magnetic hair flow sensor that can measure the speed, direction, and oscillation of flow based on its mechanical deflection. We tested the ability of these sensors on underwater robots to estimate their forward, lateral (angular) speeds and orientations. While the robots were swimming, the sensors could also detect the wake behind an upstream object by identifying its characteristic frequency.

To effectively address this problem, a hierarchical fault-tolerant control framework with fuzzy adaptive mechanisms is proposed. First, a distributed output predictor based on a finite-time differentiator is constructed for each follower to estimate the leader's output trajectory and to prevent fault propagation across the network. Second, a novel state and actuator-fault observer is designed to reconstruct unmeasured states and detect actuator faults in real time. Third, a sensor-fault compensation strategy is integrated into a backstepping procedure, resulting in a fuzzy adaptive consensus-tracking controller. This controller guarantees the uniform boundedness of all closed-loop signals and ensures that the tracking error converges to a small neighborhood of the origin. Finally, numerical simulations validate the effectiveness and robustness of the proposed method in the presence of multiple simultaneous faults and disturbances.","url":"https://doi.org/10.3390/s26010252","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s26010252","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1089/soro.2024.0113","name":"Exo-Glove Poly III: Grasp Assistance by Modulating Thumb and Finger Motion Sequence with a Single Actuator.","source":"europepmc","abstract":"","url":"https://doi.org/10.1089/soro.2024.0113","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1089/soro.2024.0113","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:12.795Z"},{"id":"doi:10.3390/biomimetics10040224","name":"Learning from Octopuses: Cutting-Edge Developments and Future Directions.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10040224","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10040224","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s44172-025-00413-6","name":"ATMO: an aerially transforming morphobot for dynamic ground-aerial transition.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s44172-025-00413-6","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s44172-025-00413-6","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10110752","name":"Bioinspired Drilling for Extraterrestrial Applications.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10110752","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10110752","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/s26031009","name":"PPO-Based Reinforcement Learning Control of a Flapping-Wing Robot with a Bio-Inspired Sensing and Actuation Feather Unit.","source":"pubmed","abstract":"Bio-inspired flow-sensing and actuation mechanisms offer a promising path for enhancing the stability of flapping-wing flying robots (FWFRs) operating in dynamic and noisy environments. This study introduces a bio-inspired sensing and actuation feather unit (SAFU) that mimics the covert feathers of falcons and serves simultaneously as a distributed flow sensor and an adaptive actuation element. Each electromechanical feather (EF) passively detects airflow disturbances through deflection and actively modulates its flaps through an embedded actuator, enabling real-time aerodynamic adaptation. A reduced-order bond-graph model capturing the coupled aero-electromechanical dynamics of the FWFR wing and SAFU is developed to provide a physics-based training environment for a proximal policy optimization (PPO) based reinforcement learning controller. Through closed-loop interaction with this environment, the PPO policy autonomously learns control actions that regulate feather displacement, reduce airflow-induced loads, and improve dynamic stability without predefined control laws. Simulation results show that the PPO-driven SAFU achieves fast, well-damped responses with rise times below 0.5 s, settling times under 1.4 s, near-zero steady-state error across varying gust conditions and up to 50% alleviation of airflow-induced disturbance effects. Overall, this work highlights the potential of bio-inspired sensing-actuation architectures, combined with reinforcement learning, to serve as a promising solution for future flapping-wing drone designs, enabling enhanced resilience, autonomous flow adaptation, and intelligent aerodynamic control during operations in gusts.","url":"https://doi.org/10.3390/s26031009","authors":["Hussain

switching controller for bidirectional trajectory tracking in PV powered mobile robots considering all their subsystems and irradiance variations.","source":"pubmed","abstract":"This paper addresses the challenge of bidirectional trajectory tracking in wheeled mobile robots (WMRs) powered by photovoltaic (PV) panels under variable irradiance. Unlike existing studies that simplify subsystem interactions, this work develops a hierarchical dynamic switching controller that integrates the WMR's dynamic model with its actuators and power electronics. This hierarchical architecture explicitly accounts for the switching nature of the power converters to manage the energy flow from the PV source while ensuring precise motion control. A key contribution of this work is the achievement of bidirectional tracking through the management of bipolar motor voltages to drive wheel velocities in both directions; this addresses a problem not previously solved in the literature when the WMR dynamic model, the power electronics subsystem, and the PV source are considered as an integrated framework. The proposed dynamic switching controller is validated through realistic simulations in MATLAB/Simulink, using the Simscape library to model both the actuators and power electronics subsystems, as well as a commercial PV panel subjected to variable irradiance profiles and abrupt parametric variations in the electrical components. The results demonstrate that the controller effectively solves the bidirectional tracking task. Furthermore, a quantitative comparison is performed between the controller proposed in this paper and another reported in the literature. The obtained indicators show the superior performance and robustness of the proposed scheme. These indicators confirm the robustness and reliability of the dynamic switching controller, demonstrating its ability to maintain precise bidirectional trajectory tracking even under sudden irradiance fluctuations and simultaneous internal parameter variations.","url":"https://doi.org/10.1038/s41598-026-47467-w","authors":["Reyes-Reyes E","Ordaz-Dehesa JC","Rodríguez-Cerón JR","Silva-Ortigoza R","Santiago-Nogales BN","García-Sánchez JR","Marciano-Melchor M","Silva-Ortigoza G"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41598-026-47467-w","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10050284","name":"Improved Anthropomorphic Robotic Hand for Architecture and Construction: Integrating Prestressed Mechanisms with Self-Healing Elastomers.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10050284","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10050284","addedAt":"2026-08-31T06:34:11.958Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1089/soro.2024.0141","name":"A Holistic Indirect Contact Identification Method for Soft Robot Proprioception.","source":"europepmc","abstract":"Soft robots hold great promise but are notoriously difficult to control due to their compliance and back-drivability.

By comparing the deviation of these sensors from their value in an unperturbed pose, we are able to perceive the mode and magnitude of deformation and thereby estimate the resulting perturbed pose of the soft actuator. We develop a sample 2 degree-of-freedom soft finger with two sensors, and we characterize sensor response to front, lateral, and twist deformation to perceive the mode and magnitude of external perturbation. We develop a data-driven model of free-bending deformation, we impose our perturbation perception method, and we demonstrate the ability to perceive perturbed pose on a single-finger and a two-finger gripper.

Traditional wheeled robots typically suffer from limitations including mobility constraints in narrow spaces, path deviations caused by ground slip, and reduced traction on rough terrain. To address these challenges, we designed a 4WIS mobile robot and implemented an architecture that independently controls the steering and driving of each wheel. The RL state space is defined by look-ahead path information, robot pose, velocity, and tracking errors, while the action space consists of target angular velocity and steering angle. To ensure robust performance, we applied random path and terrain generation and implemented domain randomization for sensors and actuators based on empirical GPS and motor data. The proposed controller was validated against the Pure Pursuit algorithm through dynamic simulations and real-world experiments. In simulations mimicking outdoor terrain, the controller reduced lateral and heading RMSE by 6.32% and 16.00%, respectively. In actual outdoor environments, it reduced these errors by 21.54% and 4.78%, respectively.

However, existing robotic systems exhibit significant limitations in replicating human-level dexterity, as well as achievable motion speed and force output. This work presents a data-driven, bio-inspired dexterous robotic hand designed specifically for high-fidelity piano performance. Methods We first extract kinematic primitives and stable inter-joint coupling patterns from large-scale motion capture data of professional pianists. These human motion priors are directly embedded into the mechanical architecture through morphological coupling and actuator allocation. Actuator selection is further guided by empirically measured human peak velocities and force profiles from biomechanics literature, ensuring sufficient bandwidth for high-speed repetitive motion and adequate force transmission. Results Experimental results demonstrate that the proposed hand replicates human-like joint coordination, achieves peak joint velocities of 53.88 rad/s, and provides sufficient fingertip force for authentic piano interaction. As a demonstration of its capabilities, the hand successfully performs a Grade 7 piano piece, Croatian Rhapsody, illustrating its potential for expressive musical performance. Conclusion This research establishes a principled pathway from human motion statistics to embodied robotic intelligence, providing a high-performance hardware foundation for autonomous musical performance.","url":"https://doi.org/10.3389/fnbot.2026.1775834","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/fnbot.2026.1775834","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10110716","name":"Recent Advancements in Humanoid Robot Heads: Mechanics, Perception, and Computational Systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10110716","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10110716","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10010035","name":"A Symmetrical Leech-Inspired Soft Crawling Robot Based on Gesture Control.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10010035","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10010035","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10110783","name":"A Two-Stage Reinforcement Learning Framework for Humanoid Robot Sitting and Standing-Up.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10110783","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10110783","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:12.795Z"},{"id":"doi:10.1126/sciadv.adx4359","name":"Multistable thin-shell metastructures for multiresponsive reconfigurable metabots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.adx4359","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1126/sciadv.adx4359","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1126/sciadv.aea8716","name":"Aerobatic maneuvers in insect-scale flapping-wing aerial robots via deep-learned robust tube model predictive control.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.aea8716","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1126/sciadv.aea8716","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41598-026-40604-5","name":"Design, manufacturing, and testing of a novel omnidirectional soft sleeve actuator.","source":"pubmed","abstract":"Soft actuators have become central to modern robotics due to their inherent flexibility, enabling safer and more adaptable interactions. Within this domain, omnidirectional actuators are particularly valuable because they enable multidirectional motion suitable for complex robotic tasks and human-robot interaction. However, existing omnidirectional actuators are often bulky and exhibit high design complexity, which limits wearability and often requires high operating pressures. This study presents a novel sleeve-type soft omnidirectional actuator (OSSA), a compact, self-contained sleeve that achieves independent linear extension and contraction and multidirectional bending through differential pressurization of a folded bellows architecture, which lowers the required pressure to 130&#xa0;kPa and enhances wearability and system integration. To enable reliable fabrication at scale, a manufacturing framework for indirect extrusion 3D printing in thermoplastic polyurethane was developed and validated, mitigating common challenges in flexible printing, including nozzle clogging and loss of airtightness. OSSA achieved 60&#xa0;N blocked axial force, 81&#xa0;mm linear displacement, 25&#xa0;mm contraction, and 18&#xa0;N bending force at angles up to 45&#xb0; under low pressure operation. A parametric analysis revealed key relationships between design geometry and material behavior, providing a framework for actuator optimization. These results advance the development of high-performance omnidirectional soft actuators for applications such as wearable robotics.","url":"https://doi.org/10.1038/s41598-026-40604-5","authors":["Abboodi M","Doumit M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41598-026-40604-5","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1089/soro.2024.0099","name":"Reprogrammable Flexible Piezoelectric Actuator Arrays with a High Degree of Freedom for Shape Morphing and Locomotion.","source":"europepmc","abstract":"","url":"https://doi.org/10.1089/soro.2024.0099","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1089/soro.2024.0099","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:12.795Z"},{"id":"doi:10.3389/frobt.2025.1681168","name":"Editorial: Advancements in vibration control for space manipulators: actuators, algorithms, and material innovations.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1681168","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1681168","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1126/sciadv.adx0465","name":"Flapping-wing robot achieves bird-style self-takeoff by adopting reconfigurable mechanisms.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.adx0465","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1126/sciadv.adx0465","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1038/s44172-026-00651-2","name":"A miniature ultrasonic surgical device based on a flextensional configuration with a pre-stressed piezoelectric stack.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s44172-026-00651-2","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s44172-026-00651-2","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.22541/au.175110551.10680435/v1","name":"Variable structure adaptive soft robot for complex pipeline environments","source":"europepmc","abstract":"","url":"https://doi.org/10.22541/au.175110551.10680435/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.22541/au.175110551.10680435/v1","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.3390/s26020470","name":"LSTM-Based Absolute Position Estimation of a 2-DOF Planar Delta Robot Using Time-Series Data.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26020470","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26020470","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:12.795Z"},{"id":"doi:10.1115/1.4068369","name":"Design and Validation of a Cable-Driven Joint Actuator for Pediatric Knee Orthoses.","source":"europepmc","abstract":"","url":"https://doi.org/10.1115/1.4068369","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1115/1.4068369","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:12.795Z"},{"id":"doi:10.5281/zenodo.19599215","name":"Starflower XVIII: The Physical Standard — Grand Invariance Synthesis Across Seventeen Papers, Morphological Transfer, and the Formally Verified Physical AI Operational Standard","source":"datacite","abstract":"ABSTRACT The Starflower Inheritance Series — seventeen papers written between March and April 2026 — establishes what we term a Physical Standard: a formally certified architecture for robotic systems in which structural invariance, the persistence of guaranteed function under bounded perturbation, is enforced simultaneously at five independent levels spanning classical logic, quantum mechanics, electromagnetic signal routing, exoskeletal actuation, and precision nanomedicine. This eighteenth paper, the Grand Invariance Synthesis, distills the entire series into its most intellectually refined form. Three contributions are new to this paper. First, the Cross-Platform Morphological Transfer (CPMT) Theorem formally states the conditions under which the Starflower safety guarantees transfer across robot morphologies — from a 22-DoF reference hand to any platform satisfying the technology-agnostic actuator envelope, including the Agibot A2 (40+ DoF, 5,168 units shipped in 2025, world leader by volume). Second, a quadruple-verified numerical audit resolves a typographic error in a circulated draft: the relative permittivity for v_p = 1.25×10⁸ m/s is ε_r = 4.79 (not 3.33 as previously stated), with material implications for the MTSM composite design. All other numbers — 146 tactile consensus checks, 26.06% velocity modulation, Z₀ = 32.78 Ω, C_Brazil = 1.53499 — are confirmed correct. Third, the Grand Invariance Table unifies all seventeen papers and all five invariance levels into a single abstract invariance theorem, situating the Starflower framework within the formal verification landscape established by Seshia (Berkeley), Lavaei (Newcastle), and the 2026 gold-medal Lean 4 achievement of Aristotle (Harmonic) at IMO 2025.

The nonlinear responses of soft actuators under dynamic loading conditions limit the use of analytic models for soft robot control. Traditional methods of controlling soft robots underutilize their configuration spaces to avoid nonlinearity, hysteresis, large deformations, and the risk of actuator damage. Furthermore, episodic data-driven control approaches such as reinforcement learning (RL) are traditionally limited by sample efficiency and inconsistency across initializations. In this work, we demonstrate RL for reliably learning control policies for dynamic balancing tasks in real-time single-shot hardware deployments. We use a deformable Stewart platform constructed using parallel, 3D-printed soft actuators based on motorized handed shearing auxetic (HSA) structures. By introducing a curriculum learning approach based on expanding neighborhoods of a known equilibrium, we achieve reliable single-deployment balancing at arbitrary coordinates. In addition to benchmarking the performance of model-based and model-free methods, we demonstrate that in a single deployment, Maximum Diffusion RL is capable of learning dynamic balancing after half of the actuators are effectively disabled, by inducing buckling and by breaking actuators with bolt cutters. Training occurs with no prior data, in as fast as 15 minutes, with performance nearly identical to the fully-intact platform. Single-shot learning on hardware facilitates soft robotic systems reliably learning in the real world and will enable more diverse and capable soft robots.","url":"https://doi.org/10.48550/arxiv.2509.19525","authors":["Avtges, James","Ketchum, Jake","Schlafly, Millicent","Young, Helena","Kim, Taekyoung","Pinosky, Allison","Truby, Ryan L.","Murphey, Todd D."],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2509.19525","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.5061/dryad.3j9kd520k","name":"Code for: Extreme dynamic symmetry enables omnidirectional and multifunctional robots","source":"datacite","abstract":"Symmetry is a central organizing principle in natural systems, yet its use as a unifying design strategy in robotics has largely remained limited to geometric form. We show that symmetry can instead be leveraged at the level of dynamic actuation capability. We introduce dynamic symmetry, the uniformity of a robot’s attainable center-of-mass accelerations, and formalize it through a measure coined as dynamic isotropy. Across more than 1,000 simulated morphologies, we find that higher dynamic symmetry consistently improves trajectory tracking, task success, robustness, resiliency, and energy efficiency, with the benefits becoming most pronounced as dynamic isotropy approaches its theoretical limit. To study this regime systematically, we develop Argus, a family of spherical robots designed to explore the effects of increasing dynamic symmetry. Members of the Argus family vary in their actuation geometry and dynamic symmetry level, while sharing a common architectural principle: radially oriented linear actuators that directly shape the robot’s center-of-mass dynamics. Among them, we build a physical 20-leg Argus variant that achieves near-extreme dynamic isotropy and demonstrates orientation-invariant locomotion, agile traversal of cluttered and deformable terrain, rapid self-stabilization, and resilience to partial actuator failures. Its distributed sensing further enables omnidirectional perception and object interaction during continuous motion. These results show that designing robots for symmetry not only in morphology but also in their attainable dynamics provides a powerful and general pathway toward agility, robustness, and multifunctionality in uncertain terrestrial and extraterrestrial environments.","url":"https://doi.org/10.5061/dryad.3j9kd520k","authors":["Liu, Jixun","Xia, Boxi","Chen, Boyuan"],"tags":["FOS: Engineering and technology","Symmetry","Robots","Dynamics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5061/dryad.3j9kd520k","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.5281/zenodo.20640270","name":"RIGEL-WEB: The Real-World Interactive Games and Electronics Link as a Self-Contained HTML Sensor Interface Invented by Subverting Web Browser Architecture for Authentic STEM Learning.","source":"datacite","abstract":"Overview This record deposits the Real-world Interactive Games and Electronics Link (RIGEL) browser port: a self-contained single-file HTML application (~5100 lines). It recreates the original Windows-based RIGEL application that connects low-cost DIY sensors, wearable biomedical sensors, and microcontrollers to real-time data logging, life function monitoring, and game control interfaces. RIGEL-WEB is a cross-platform, installation-free browser application that connects a computer to microcontroller-based sensor units (Picaxe 08M2/14M2, Arduino, ESP8266, ESP32, BBC Micro:bit) via USB-serial, Bluetooth, or WiFi. RIGEL-WEB provides a suite of STEM education modules: Science Lab (multi-sensor display with data logging), Home Security (floor plan with sensor pins and alarm management), CPR Simulator (rate, depth, and blood-oxygen monitoring), 2D Sensor Game (two-axis bipolar sensor control), 3D Flight Simulator (pitch and roll sensor control), Robot Remote Control (bidirectional sensor and actuator interface), and Industrial Measurement and Control (process gauges, actuator panel, and IF-THEN rule engine). The application runs in Chrome and Edge (Chromium) only, requiring the Web Serial API and File System Access API available in those browsers. The original RIGEL system was developed in 2008 using GameMaker 6 — itself an instance of Design by Subversion (DbS) in which a game design application was subverted into a universal real-time science instrument by substituting serial sensor data for keyboard events (Fenton, 2009, doi:10.5281/zenodo.19334228). The browser port constitutes a further technical-strand subversion: modern browsers have evolved into general-purpose application platforms containing every subsystem a science instrument requires — Web Serial API, File System Access API, Web Audio API, SpeechSynthesis API, Canvas API, localStorage, and IndexedDB — without those subsystems having been assembled by browser developers for science education. The single-file self-contained architecture exploits the browser’s ability to run a complete application from a local HTML file without a server, removing the installation and hosting dependencies that would otherwise reproduce the original Windows constraint in a new form. The deposit includes: the HTML application; a Design by Subversion analysis establishing that the application meets the framework’s operational tests as a technical-strand subversion and that its development constitutes part of the first documented prospective application of the framework; and screenshots of all seven modules in light or dark themes.; a short movie clip of navigating and using the application in demosntration mode. A sister application, SMART — Sound-to-Motion Analysis and Recording Tool (doi.org/10.5281/zenodo.20542011) — was developed subsequently using the same single-file no-framework architecture, exploiting the browser’s audio subsystem as a precision physics event-timer and frequency analyser. RIGEL-WEB and SMART together form a complementary zero-cost cross-platform laboratory instrument suite covering the sensor range of commercial equipment costing several thousand dollars. Significance as primary-source evidence This deposit is significant in five areas. As a technical-strand extension of the Design by Subversion framework — operating at two scales simultaneously. The original RIGEL (GameMaker, 2008) is one of four canonical examples in the Design by Subversion technical note (Fenton, 2026, doi:10.5281/zenodo.19547774). The browser port constitutes a further technical-strand subversion operating at two distinct scales that should be named separately. At the parent scale, the browser as an application platform was designed to deliver web content from servers.

RIGEL-WEB provides a suite of STEM education modules: Science Lab (multi-sensor display with data logging), Home Security (floor plan with sensor pins and alarm management), CPR Simulator (rate, depth, and blood-oxygen monitoring), 2D Sensor Game (two-axis bipolar sensor control), 3D Flight Simulator (pitch and roll sensor control), Robot Remote Control (bidirectional sensor and actuator interface), and Industrial Measurement and Control (process gauges, actuator panel, and IF-THEN rule engine).

The browser port constitutes a further technical-strand subversion: modern browsers have evolved into general-purpose application platforms containing every subsystem a science instrument requires — Web Serial API, File System Access API, Web Audio API, SpeechSynthesis API, Canvas API, localStorage, and IndexedDB — without those subsystems having been assembled by browser developers for science education.

First, the Cross-Platform Morphological Transfer (CPMT) Theorem formally states the conditions under which the Starflower safety guarantees transfer across robot morphologies — from a 22-DoF reference hand to any platform satisfying the technology-agnostic actuator envelope, including the Agibot A2 (40+ DoF, 5,168 units shipped in 2025, world leader by volume). Second, a quadruple-verified numerical audit resolves a typographic error in a circulated draft: the relative permittivity for v_p = 1.25×10⁸ m/s is ε_r = 4.79 (not 3.33 as previously stated), with material implications for the MTSM composite design. All other numbers — 146 tactile consensus checks, 26.06% velocity modulation, Z₀ = 32.78 Ω, C_Brazil = 1.53499 — are confirmed correct. Third, the Grand Invariance Table unifies all seventeen papers and all five invariance levels into a single abstract invariance theorem, situating the Starflower framework within the formal verification landscape established by Seshia (Berkeley), Lavaei (Newcastle), and the 2026 gold-medal Lean 4 achievement of Aristotle (Harmonic) at IMO 2025.

While these scaling laws have been explored in a variety of microsystems, the benefits and limitations of downscaling 3D robotic mechanisms have yet to be assessed due to limitations in microscale 3D manufacturing. In this work, we use the Delta robot as a case study for these scaling laws. We present two sizes of 3D-printed Delta robots, the microDeltas, measuring 1.4 mm and 0.7 mm in height, which are the smallest and fastest Delta robots ever demonstrated. 3D printing with two-photon polymerization and subsequent metallization enabled the miniaturization of these 3D robotic parallel mechanisms integrated with electrostatic actuators for exceptionally high bandwidths. The smallest microDelta was able to operate at over 1000 Hz and achieved precisions of less than 1 µm by taking advantage of its small size. The microDelta's relatively high output power was demonstrated with the launch of a small projectile, highlighting the utility of miniaturized robotic systems for applications ranging from manufacturing to haptics.","url":"https://doi.org/10.5061/dryad.7pvmcvf56","authors":["Man, Steven","Kim, Sukjun","Bergbreiter, Sarah"],"tags":["FOS: Mechanical engineering","FOS: Mechanical engineering","Robotics","Electrostatics","3D printing"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.5061/dryad.7pvmcvf56","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:11.959Z"},{"id":"doi:10.48550/arxiv.2601.11143","name":"Learning Quadrupedal Locomotion for a Heavy Hydraulic Robot Using an Actuator Model","source":"datacite","abstract":"The simulation-to-reality (sim-to-real) transfer of large-scale hydraulic robots presents a significant challenge in robotics because of the inherent slow control response and complex fluid dynamics. The complex dynamics result from the multiple interconnected cylinder structure and the difference in fluid rates of the cylinders.

In this work, we propose an analytical actuator model driven by hydraulic dynamics to represent the complicated actuators. The model predicts joint torques for all 12 actuators in under 1 microsecond, allowing rapid processing in RL environments. We compare our model with neural network-based actuator models and demonstrate the advantages of our model in data-limited scenarios. The locomotion policy trained in RL with our model is deployed on a hydraulic quadruped robot, which is over 300 kg.

(RED ALERT) ........................................................................................................................................................................................................................................................................... MH 370 AT IGARI Point. (18:25 UTC on 8 March 2014) Twelve years of fruitless searching for MH 370 marked the greatest computational error in the history of aviation, because the world was looking for the wreckage of a classic crash, whereas the actual event was a tensorial transfer at the IGARI point. At 18:25 UTC on 8 March 2014, eyewitnesses such as the New Zealander Michael McKay from the Songa Mercur oil platform and the British mariner Catherine T. reported a dense, orange-coloured luminosity in the sky—an effect not caused by hydrocarbon fuel combustion, but by atmospheric ionisation and plasma formation at the moment of entry into a 165-dimensional tensor tunnel due to the cyclotron resonance of the lithium ions in the 221 kg payload with electromagnetic radar waves, the aircraft’s weather radar system, the magnetic fields of the Trent 800 engines, the interaction with concentrated oxygen in the cargo hold, the composite fuselage structure, the Class G1 magnetic storm, and the Earth’s plasmasphere of the 8 March 2014. During this dimensional rupture, key components such as the flaperon were not separated due to physical impact with the sea, but rather as a consequence of tensorial stress and phase mismatch at an altitude of 35,000 feet. Through a mechanism known as tangential disc ejection, and under the influence of extreme rotational velocity, these elements detached from the airframe and—rather than falling locally—were projected westwards towards Malaysia and the equatorial currents. The asymmetric concentration of recovered debris—particularly the retrieval of heavy structural components from the aircraft’s right front section (such as the flaperon and outer flap), contrasted with only a single trailing edge from the left front—supports the mechanism of a “tangential ejection caused by tensorial torque” at the IGARI point. This metallurgical asymmetry indicates that the right front section, subjected to intense centrifugal force, experienced physical disintegration before full entry into the protective bubble. $\\text{Dedicated Lagrangian Proof for Asymmetric Tangential Ejection at IGARI}$ $$\\mathcal{L}_{IGARI}^{(165)} = \\int_{\\mathcal{M}_{35kft}} \\left( \\underbrace{\\frac{1}{2} \\mathcal{I}_{ij} \\omega^{i} \\omega^{j}}_{\\text{Tangential Torque}} + \\overbrace{\\oint_{\\partial \\text{Right}} \\vec{\\mathcal{T}}_{shear} \\cdot d\\vec{A}}^{\\text{Asymmetric Disintegration}} - \\underbrace{\\Phi_{plasma} \\left( \\vec{j}_{Li} \\cdot \\vec{E}_{ext} \\right)}_{\\text{Orange Luminosity Index}} \\right) \\sqrt{-\\mathbb{G}_{165}} \\, d^4x$$ $\\text{Where:}$ $\\text{Right-Wing Instability Condition:}$ $$\\frac{\\delta \\mathcal{L}}{\\delta q_{Right}} \\Big|_{18:25Z} \\gg \\sigma_{yield} \\implies \\text{Ejection of Flaperon/Outer Flap}$$ $\\text{Tangential Velocity Projection (Vector Proof):}$ $$\\vec{V}_{debris} = \\left[ \\vec{\\omega}_{tensor} \\times \\","url":"https://doi.org/10.5281/zenodo.18220588","authors":["JALALI, SEYED RASOUL"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.18220588","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.5281/zenodo.18237334","name":"MH370: Mathematical Proof of the Survival of All Passengers Within a Tensorial Capsule at Broken Ridge and a Depth of 4650 Meters in the Southern Indian Ocean, at Coordinates Longitude 93.6165° E and Latitude 34.4812° S via 165D Mechanics Tensor of the Hamzah Equation.","source":"datacite","abstract":"Hamzah Quantum Intelligence (HQI). ................................................................................................................................................................................................................................................................. 12 Years Classical Search Method (2014-2026) for MH 370 Was Exactly Like Trying to See X-rays While Wearing Sunglasses — A Completely Wrong Tool for an Entirely Different Task.” .................................................................................................................................................................................................................................................................

Historical Proof of Dangerous Z-Zone: The severing of the Fugro cable in 2016 and the escape of the Ocean Infinity drone in 2018 were by no means accidental; rather, they constituted a systematic response of the “Tensor Diamond” to level-3 distance violations. Both incidents (the Fugro cable cut in 2016 and the escape of the Ocean Infinity drone in 2018 with intense drone manoeuvres) occurred at exactly 165 metres of MH370.(Longitude 93.6165° E and Latitude 34.4812° S). 1. Theoretical Framework To substantiate the 165-metre radius, the Lagrangian must incorporate the Metric Interaction Term ($\\Xi_{SIO}$).

These modular components are intended primarily for robotic systems in space exploration and construction on the Moon in our Moonshot project. Such modular robots add flexibility and versatility for space missions where resources are constrained. Each module is driven by a common actuator characterized by a high torque-to-speed ratio, supporting both precise control and dynamic motion when required. This unified actuator design simplifies development and maintenance across the different module types. The paper describes the hardware implementation, the mechanical design of the modules, and the overall software architecture used to control and coordinate them. Additionally, we evaluate the control performance of the actuator under various load conditions to characterize its suitability for modular robot applications. To demonstrate the adaptability of the system, we introduce nine functional configurations assembled from the same set of modules: 4DOF-limb, 8DOF-limb, vehicle, dragon, minimal, quadruped, cargo, cargo-minimal, and bike. These configurations reflect different locomotion strategies and task-specific behaviors, offering a practical foundation for further research in reconfigurable robotic systems.","url":"https://doi.org/10.48550/arxiv.2601.04541","authors":["Diaz, Gustavo H.","Jain, A.

Executive Preface: The Shift from Machine to Organism 1.1 The Metabolic Imperative The trajectory of consumer robotics has long been defined by a fundamental functional dissonance: humanity engineers machines to serve life, yet constructs them using the logic of extraction, depletion, and thermodynamic isolation. The traditional robot is, in essence, a thermodynamic island—a closed system of high-energy potential (lithium-ion chemistry) encased in rigid, high-entropy materials (injection-molded ABS, mined aluminum) that stand apart from the environments they occupy.1 These machines do not breathe; they consume. They do not heal; they degrade. They do not collaborate with their surroundings; they impose upon them until their energy reserves actuate a shutdown or their mechanical components succumb to fatigue. The Immortal Tek Dovermane X represents a definitive break from this industrial lineage. It is not designed merely as a robotic appliance, but as a synthetic organism—a \"metabolic\" companion that functions closer to a biological entity than a consumer device. By integrating principles from the CollectiveOS Bio-Economy Stack, the Dovermane X transitions from the \"extractive-combustive\" paradigm of traditional engineering to a \"resonant-metabolic\" paradigm.1 It is engineered to absorb, organize, and redistribute ambient environmental flows—light, humidity, thermal gradients, and mechanical resonance—into a coherent, stabilized form of agency. This white paper articulates the comprehensive technical architecture of the Dovermane X. It details the bio-composite material science that grants it a self-healing body, the \"Metabolic Engine\" that affords it energy autonomy, the insect-inspired optical systems that provide it with hyper-fast temporal perception, and the \"Constraint-First\" AI architecture that ensures its behavior remains mathematically aligned with human safety and well-being. This document serves as a blueprint for a machine that does not simply exist in the world, but lives with it. 1.2 Defining the Companion Class The Dovermane X is a quadrupedal, bio-composite companion platform engineered for proxemic intimacy and long-horizon stewardship. Unlike industrial quadrupeds designed for remote surveillance or heavy payload transport, the Dovermane X is optimized for the nuanced, unstructured reality of the human home.

Executive Preface: The Shift from Machine to Organism 1.1 The Metabolic Imperative The trajectory of consumer robotics has long been defined by a fundamental functional dissonance: humanity engineers machines to serve life, yet constructs them using the logic of extraction, depletion, and thermodynamic isolation. The traditional robot is, in essence, a thermodynamic island—a closed system of high-energy potential (lithium-ion chemistry) encased in rigid, high-entropy materials (injection-molded ABS, mined aluminum) that stand apart from the environments they occupy.1 These machines do not breathe; they consume. They do not heal; they degrade. They do not collaborate with their surroundings; they impose upon them until their energy reserves actuate a shutdown or their mechanical components succumb to fatigue. The Immortal Tek Dovermane X represents a definitive break from this industrial lineage. It is not designed merely as a robotic appliance, but as a synthetic organism—a \"metabolic\" companion that functions closer to a biological entity than a consumer device. By integrating principles from the CollectiveOS Bio-Economy Stack, the Dovermane X transitions from the \"extractive-combustive\" paradigm of traditional engineering to a \"resonant-metabolic\" paradigm.1 It is engineered to absorb, organize, and redistribute ambient environmental flows—light, humidity, thermal gradients, and mechanical resonance—into a coherent, stabilized form of agency. This white paper articulates the comprehensive technical architecture of the Dovermane X. It details the bio-composite material science that grants it a self-healing body, the \"Metabolic Engine\" that affords it energy autonomy, the insect-inspired optical systems that provide it with hyper-fast temporal perception, and the \"Constraint-First\" AI architecture that ensures its behavior remains mathematically aligned with human safety and well-being. This document serves as a blueprint for a machine that does not simply exist in the world, but lives with it. 1.2 Defining the Companion Class The Dovermane X is a quadrupedal, bio-composite companion platform engineered for proxemic intimacy and long-horizon stewardship. Unlike industrial quadrupeds designed for remote surveillance or heavy payload transport, the Dovermane X is optimized for the nuanced, unstructured reality of the human home. It is not a tool for labor, but a node for connection. Its primary function is to bridge the gap between the digital and physical worlds, acting as an embodied agent of the CollectiveOS that navigates domestic spaces with a rigorous, mathematically provable safety profile.2 This document adheres to a \"Public-Safe\" disclosure standard.

These new capabilities are the result of a physics-informed design with an enlarged head and shortened tail relative to those of the original platform. Enhanced by its design, this new platform achieves forward swimming speeds of up to 13.6 mm/s (0.38 Bl/s), which is over four times that of the original platform. Furthermore, when following 2D references in closed loop, the tested FRISSHBot prototype attains forward swimming speeds of up to 9.1 mm/s, root-mean-square (RMS) tracking errors as low as 2.6 mm, turning rates of up to 13.1 °/s, and turning radii as small as 10 mm.","url":"https://doi.org/10.48550/arxiv.2508.07566","authors":["Trygstad, Conor K.","Longwell, Cody R.","Gonçalves, Francisco M.

The assembly was made from a modular CRC system composed of robotic actuators and timber structs, more information on the system can be found in the paper. The prototype was assembled using four robotic actuators composed into two kinematic chains, each connected with a single timber strut. &lt;p&gt; &lt;p&gt; The data set contains 19 robotic plans in JSON file format. Each plan or JSON file correlate to one of the 19 timber struts that were placed into the structure. Each plan contains information on the robotic actuators and timber struts within the scene as JSON Objects. Within each JSON Object, the position and location of part of the CRC system is described with different amounts of keyframes. The keyframes represent moments in the assembly process when at least one robotic actuator in the scene opens or closes its gripper. &lt;p&gt; &lt;p&gt; Timber struts, identified with the key:value pair &lt;i&gt;\"frame_name\": \"s0\"&lt;/i&gt; as one example, contain information on the position and orientation of the strut.

An array of such microspines, when integrated into the limbs or undercarriage of a robot, can provide the ability to maneuver uneven terrains, traverse inclines, and even climb walls. Conformability and adaptability of soft robots makes them ideal candidates for these applications involving traversal of complex, unstructured terrains. However, there remains a real-life realization gap for soft locomotors pertaining to their transition from controlled lab environment to the field by improving grip stability through effective integration of microspines. We propose a passive, compliant microspine stacked array design to enhance the locomotion capabilities of mobile soft robots, in our case, ones that are motor tendon actuated. We offer a standardized microspine array integration method with effective soft-compliant stiffness integration, and reduced complexity resulting from a single actuator passively controlling them. The presented design utilizes a two-row, stacked microspine array configuration that offers additional gripping capabilities on extremely steep/irregular surfaces from the top row while not hindering the effectiveness of the more frequently active bottom row. We explore different configurations of the microspine array to account for changing surface topologies and enable independent, adaptable gripping of asperities per microspine. Field test experiments are conducted on various rough surfaces including concrete, brick, compact sand, and tree roots with three robots consisting of a baseline without microspines compared against two robots with different combinations of microspine arrays. Tracking results indicate that the inclusion of microspine arrays increases planar displacement on average by 15 and 8 times.","url":"https://doi.org/10.48550/arxiv.2502.12347","authors":["Ervin, Lauren","Bezawada, Harish","Vikas, Vishesh"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2502.12347","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:11.959Z"},{"id":"doi:10.5281/zenodo.13768819","name":"Research data supporting 'Highly agile flat swimming robot'","source":"datacite","abstract":"The dataset supporting 'Highly agile flat swimming robot', published in Science Robotics in 2025 under the DOI: 10.1126/scirobotics.adr0721.

The system, named SPLITTER, comprises two sub-10 kg quadrupedal robots connected by a tether, capable of executing successive jumping gaits and stabilizing in-flight using inertial morphing technology. Through model predictive control (MPC), attitude control was demonstrated by adjusting the limbs and tether length to modulate the system's principal moments of inertia. Our results indicate that this control strategy allows the robot to stabilize during flight phases without needing traditional flywheel-based systems or relying on aerodynamics, making the approach mass-efficient and ideal for small-scale planetary robots' successive jumps.

We develop a powerful and lightweight latched series-elastic actuator using a twisted string and carbon fiber springs.

Here we report a fully stretchable, shape-agnostic electronic skin that overcomes this limitation to enable unified three-dimensional (3D) tactile–morphological perception. This breakthrough integrates a shape-conforming, stretchable architecture with tomography-inspired sensing and a physics-informed inversion pipeline to decouple co-occurring mechanical inputs and reconstruct sub-millimetre shape deformations while simultaneously mapping external touch or hydrodynamic stimuli at over 30 Hz. We demonstrate that this sensory feedback closes the sensorimotor loop by enabling diverse autonomous behaviours from adaptive locomotion and evasive swimming to intuitive human-robot interaction.

This addresses the limitations of current solutions, which often rely on proprietary hardware and software, limiting their accessibility and customizability, or comprise ad-hoc pipelines tailored to specific use cases. Approach We developed NeuroSimo, a software platform that enables arbitrary EEG–TMS stimulation protocols written in Python, leveraging Python’s ecosystem of scientific, neuroimaging, and machine learning libraries. The core software is written in C++ with an embedded Python interpreter and employs the Robot Operating System (ROS 2) for inter-process communication. NeuroSimo runs on real-time-enabled Linux Ubuntu, using LabJack T4 for pulse triggering, and supports two EEG device models (Bittium NeurOne, BrainProducts actiCHamp) and TMS devices that deliver pulses via trigger signals. The software includes a graphical user interface for configuration and performance monitoring, and supports GPU processing for neural network computations. Main results In brain-state-dependent stimulation using the Phastimate algorithm, which targets TMS pulses to the trough of sensorimotor μ-rhythm, NeuroSimo achieved a median timing error of 0.2 ms (95% CI: 0.2–0.2 ms), a 99th-percentile of 0.6 ms (0.6–0.6 ms), and a maximum of 1.4 ms. Significance As an open-source platform combining Python’s flexibility with real-time closed-loop EEG–TMS, NeuroSimo enables researchers to develop and implement novel therapeutic approaches, marking a significant advance in personalized brain stimulation.","url":"https://doi.org/10.1101/2025.04.05.647342","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.04.05.647342","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.1101/2023.09.25.559130","name":"FARMS: Framework for Animal and Robot Modeling and Simulation","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2023.09.25.559130","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1101/2023.09.25.559130","addedAt":"2026-08-31T06:34:11.959Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.36652/10.36652/0042-4633-2024-103-3-205-211","name":"Algorithm for controlling a spherical robot with a pendulum actuator in the problem of pursuing and hitting a moving target","source":"crossref","abstract":"An algorithm is developed to control a spherical robot with a pendulum actuator through servoconstraints, generating the necessary control torque.

In such scenarios, the collaboration of such heterogeneous robots demands effective communication for task completion.

This paper proposes an IoRT-based middleware that allows the communication of different types of robot operating systems in dynamic environments, using a cloud-based protocol. This middleware facilitates task assignment, training, and planning for heterogeneous robots, while enabling distributed communication via WiFi. The system operates in two control modes: local and cloud-based, for flexible communication and information distribution. This work highlights the challenges of current communication methods, particularly in ensuring information reach, agility, and handling diverse robots. To demonstrate the middleware suitability and applicability, an implementation of a proof-of-concept is shown in a touristic scenario where several guide robots can collaborate by effectively sharing information gathered from their heterogeneous sensor systems, with the aid of cloud processing or even internal communication processes. Results show that the performance of the middleware allows real-time applications for heterogeneous multi-robot systems in different domains.","url":"https://doi.org/10.3390/jsan13060087","authors":["Emil Cuadros Zegarra","Dennis Barrios Aranibar","Yudith Cardinale"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-17T05:26:02Z","doi":"10.3390/jsan13060087","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/iceace63551.2024.10898395","name":"Control of switchgear actuator of substation inspection and disposal robot based on teleoperation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iceace63551.2024.10898395","authors":["Yuan Jia","Hao Zhang","Jiawei Wang","Yiming Chen","Zijian Yang","Huijuan Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-03-03T18:27:26Z","doi":"10.1109/iceace63551.2024.10898395","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1109/iros58592.2024.10801795","name":"Multistable Soft Actuator for Physical Human-robot Interaction","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros58592.2024.10801795","authors":["Juncai Long","Jituo Li","Xiaojie Diao","Chengdi Zhou","Guodong Lu","Yixiong Feng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-25T19:17:39Z","doi":"10.1109/iros58592.2024.10801795","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1007/s41315-024-00355-w","name":"Design optimisation and an experimental assessment of soft actuator for robotic grasping","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s41315-024-00355-w","authors":["Dhruba Jyoti Sut","Prabhu Sethuramalingam"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-20T12:01:51Z","doi":"10.1007/s41315-024-00355-w","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.3103/s1068798x2470076x","name":"Algorithm for Controlling a Spherical Robot with a Pendulum Actuator in the Problem of Pursuing and Hitting a Moving Target","source":"crossref","abstract":"","url":"https://doi.org/10.3103/s1068798x2470076x","authors":["E.

However, realizing such enhancement is challenging. A proposed solution for active body weight support systems involves employing a macro–mini linear actuator incorporating an electrorheological-fluid brake to connect a high-force unit with an agile, highly back-drivable unit. This paper introduces the use of an electromagnetic (EM) brake with reduced rotor inertia to address this challenge. The increased torque capacity of the EM brake enables integration with a low-gear-ratio linear transmission. The agile translation of the endpoint is propelled by a low-inertia motor (referred to as the “mini”) via a pulley-belt mechanism to achieve high transparency. The rotor of the EM brake is linked to the pulley. Damping modulation under high driving force is achieved through the adjustment of the brake torque relative to the rotational speed of the pulley. When the brake is engaged, it prevents any relative motion between the endpoint and the moving carrier. The endpoint is fully controlled by the ball screw of the high-force unit, referred to as the “macro”. A scaled prototype was constructed to experimentally characterize the damping force generated by the mini motor and the EM brake.

Furthermore, aerospace manufacturing and assembly sites are often unstructured environments not specifically suitable for robots to operate in. Methods: This paper introduces a robotic visual inspection system using off-the-shelf components able to inspect the mounting holes for wing slat actuators without the need for fixed-coordinate programming; the part just needs to be left within reach of the robot. Our system sets one of the opposed pairs of mounting holes as a reference (the “datum”) and then compares the tilt of all other pairs of mounting holes with respect to it. Under the assumption that any deviation in the mounting hole tilt is not systematic but due to normal manufacturing tolerances, our system will either guarantee the correct alignment of all mounting holes or highlight the existence of misaligned holes. Results and Discussion: Computer-vision tilt measurements are performed with an error of below 0.03° using custom optimization for the sub-pixel determination of the center and radius of the mounting holes. The error introduced by the robot’s motion from the datum to each of the remaining hole pairs is compensated by moving back to the datum and fixing the orientation again before moving to inspect the next hole pair. This error is estimated to be approximately 0.05°, taking the total tilt error estimation for any mounting hole pair to be 0.08° with respect to the datum. This is confirmed by manually measuring the tilt of the hole pairs using a clock gauge on a calibrated table (not used during normal operation).","url":"https://doi.org/10.3389/frobt.2024.1423319","authors":["Nour M.

To address these challenges, we propose a novel design of soft artificial muscle that utilizes shape memory alloy (SMA) spring actuators with pre-detwinning process. The SMA spring was fabricated through a process called pre-detwinning, which enhances the linearity of the SMA spring in martensite phase and unpowered restoring force, which is called passive force.

Finally, the soft wearable robot that can assist not only the gravitational torque exerted on the elbow by passive force, but also the elbow movements with active force was designed with a soft artificial muscle. A soft artificial muscle consists of the bundles of pre-detwinned SMA springs integrated with the stretchable coolant vessel. The stiffness of the muscle was measured as 1125 N/m in martensite phase and 1732 N/m in austenite phase. In addition, the muscle showed great actuation frequency performances, the bandwidth of which was measured as 0.5 Hz.

However, they are often limited by their low output power, which can make their integration into dynamic systems like hopping robots particularly challenging. This research optimizes the performance by introducing a cone DEA with a novel type of semi-diamond preload mechanism. This type of preload mechanism can meet the requirements of a negative-stiffness preload and a light weight. According to the experiments, the DEA can provide 3.62 mW power and its mass is only about 17.5 g. In order to drive hopping robots based on a cone DEA, this research introduces an energy accumulation mechanism coupled with a constant-torque cam for a hopping robot. The hopping robot weighs approximately 30.3 g and stands 10 cm tall in its upright position. Its energy accumulation mechanism involves a gear and cam transmission system, which is the key to store and release energy efficiently. The primary components of this mechanism include a torsion spring that stores mechanical energy when twisted, a constant-torque actuation cam that ensures the consistent application of torque during the energy storage phase, and a conical DEA that acts as an actuator. When the conical DEA is activated, it pushes a one-way clutch to the rocker, rotating the gear and cam mechanism and subsequently twisting the torsion spring to store energy. Upon release, the stored energy in the torsion spring is rapidly converted into kinetic energy, propelling the robot into the air. The experiments reveal that the designed DEA can drive the hopping robot by using the energy storage mechanism. Its hopping height is related to the pre-compression angle of the torsion spring. The DEA can drive the rigid hopping mechanism, and the maximum hopping height of the robot is up to 2.5 times its height. DEA hopping robots have obvious advantages, such as easy control, quietness and safety.","url":"https://doi.org/10.3390/act14010003","authors":["Yunguang Luan","Huaming Wang","Ling Zhou","Haichao Song"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-26T19:33:07Z","doi":"10.3390/act14010003","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1201/9788770047500-4","name":"Introduction to Shape Memory Alloy Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1201/9788770047500-4","authors":["Ermira Junita Abdullah"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-04T10:35:22Z","doi":"10.1201/9788770047500-4","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1109/icarm62033.2024.10715868","name":"Mechanical Design of a Compliant Spine using Series Elastic Actuator for Quadruped Robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icarm62033.2024.10715868","authors":["Jiahao Su","Siyu Liu","Chunlei Lu","Zhirui Wang","Tong Yan","Bo Su","Zhao Guo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-18T17:27:32Z","doi":"10.1109/icarm62033.2024.10715868","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1109/icarm62033.2024.10715827","name":"Practical Prescribed-Time Fault-Tolerant Control for Robot Manipulators Involving Abrupt Actuator Faults and Position Error Constraints","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icarm62033.2024.10715827","authors":["Pengxin Yang","Shuang Zhang","Xinbo Yu","Wei He"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-18T17:27:32Z","doi":"10.1109/icarm62033.2024.10715827","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.3389/frobt.2024.1302862","name":"Evaluation of fabric-based pneumatic actuator enclosure and anchoring configurations in a pediatric soft robotic exosuit","source":"crossref","abstract":"Introduction Soft robotics play an increasing role in the development of exosuits that assist, and in some cases enhance human motion. While most existing efforts have focused on the adult population, devices targeting infants are on the rise. This work investigated how different configurations pertaining to fabric-based pneumatic shoulder and elbow actuator embedding on the passive substrate of an exosuit for pediatric upper extremity motion assistance can affect key performance metrics. Methods The configurations varied based on actuator anchoring points onto the substrate and the type of fabric used to fabricate the enclosures housing the actuators. Shoulder adduction/abduction and elbow flexion/extension were treated separately. Two different variants (for each case) of similar but distinct actuators were considered. The employed metrics were grouped into two categories; reachable workspace, which includes joint range of motion and end-effector path length; and motion smoothness, which includes end-effector path straightness index and jerk. The former category aimed to capture first-order terms (i.e., rotations and displacements) that capture overall gross motion, while the latter category aimed to shed light on differential terms that correlate with the quality of the attained motion. Extensive experimentation was conducted for each individual considered configuration, and statistical analyses were used to establish distinctive strengths, weaknesses, and trade-offs among those configurations. Results The main findings from experiments confirm that the performance of the actuators can be significantly impacted by variations in the anchoring and fabric properties of the enclosures while establishing interesting trade-offs. Specifically, the most appropriate anchoring point was not necessarily the same for all actuator variants. In addition, highly stretchable fabrics not only maintained but even enhanced actuator capabilities, in comparison to the less stretchable materials which turned out to hinder actuator performance. Conclusion The established trade-offs can serve as guiding principles for other researchers and practitioners developing upper extremity exosuits.","url":"https://doi.org/10.3389/frobt.2024.1302862","authors":["Ipsita Sahin","Mehrnoosh Ayazi","Caio Mucchiani","Jared Dube","Konstantinos Karydis","Elena Kokkoni"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-11T03:56:11Z","doi":"10.3389/frobt.2024.1302862","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1109/lra.2024.3366016","name":"Robust Elastic Structure Preserving Control for High Impedance Rendering of Series Elastic Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3366016","authors":["Hyunwook Lee","Jinoh Lee","Manuel Keppler","Sehoon Oh"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-14T19:00:54Z","doi":"10.1109/lra.2024.3366016","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1007/978-981-97-5675-9_11","name":"Adaptive Fixed-Time Sliding-Mode Trajectory Tracking Control of a Cart-Pendulum Robot Against Actuator Attacks","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-97-5675-9_11","authors":["Jiadong Liu","Zhiye Zhao","Xiaozheng Jin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-01T01:10:40Z","doi":"10.1007/978-981-97-5675-9_11","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1201/9788770047500-5","name":"Devices and Wearables using Shape Memory Alloy Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1201/9788770047500-5","authors":["Ermira Junita Abdullah"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-04T10:35:22Z","doi":"10.1201/9788770047500-5","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1109/aim55361.2024.10637183","name":"Design and Optimization of a Cable Tension Force Sensor for a Low-cost Custom Continuum Robot Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim55361.2024.10637183","authors":["Dai-Dong Nguyen","Phuc Thanh-Thien Nguyen","Shun-Feng Su","Yu-Cheng Kuo","Chung-Hsien Kuo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-22T17:52:35Z","doi":"10.1109/aim55361.2024.10637183","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1145/3613905.3650922","name":"Integration of a Shape Memory Alloy with a Soft Pneumatic Actuator to Improve the Haptic Interaction Performance of a Soft Social Robot","source":"crossref","abstract":"","url":"https://doi.org/10.1145/3613905.3650922","authors":["Youchan Yim","Fumihide Tanaka"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-05-11T08:15:21Z","doi":"10.1145/3613905.3650922","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.1016/j.ins.2024.120303","name":"Adaptive fuzzy sliding mode control of uncertain nonholonomic wheeled mobile robot with external disturbance and actuator saturation","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.ins.2024.120303","authors":["Yunjun Zheng","Jinchuan Zheng","Ke Shao","Han Zhao","Zhihong Man","Zhe Sun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-09T00:32:44Z","doi":"10.1016/j.ins.2024.120303","addedAt":"2026-08-31T06:34:11.995Z","updatedAt":"2026-08-31T06:34:11.995Z"},{"id":"doi:10.3390/mi17050608","name":"Toward the Advancement of Soft Pneumatic Rotary Actuators: A Comprehensive Design Review.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi17050608","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/mi17050608","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1038/s41598-026-48968-4","name":"Applications of artificial intelligence in mechanical engineering for the field of upper limb exoskeletons.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-026-48968-4","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41598-026-48968-4","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1002/adma.202519692","name":"Freeform Manufacturing of Plant-Based Structural Colors for Scalable Photonic and Mechanochromic Devices.","source":"pubmed","abstract":"Plant-based, iridescent, and dynamically tunable structural colored materials are highly attractive for sustainable photonic devices. However, fabricating complex architectures at the decimeter-scale with optical fidelity using plant-derived materials remains challenging, limiting their use in photonic devices and adaptive actuation. Here, we introduce an aqueous two-phase freeform fabrication strategy for vibrantly colored hydroxypropyl cellulose (HPC), where a robust immiscible aqueous environment is developed to preserve HPC cholesteric structures with &lt; 3% shift in peak reflection wavelength over three days, enabling stable processing of large-scale structural colored materials. Our technique involves a food-grade support medium with low interfacial tension, allowing for embedded 3D printing of photonic structures and post-extrusion recovery of the HPC cholesteric domains. Intricate constructs, including interlocking chainmail, with feature sizes down to &#x223c;50&#xa0;&#xb5;m and color consistency over lengths exceeding ten centimeters, can be achieved. Additionally, this approach can be utilized to create non-planar, mechanochromic hydrogel actuators with programmable multicolor designs, as demonstrated in an octopus-inspired hydrogel actuator and a color-shifting display for information encryption, camouflage, and human-machine interaction. Our green, freeform manufacturing approach provides new design possibilities for sustainable photonic devices and can be applied to industrially relevant applications.","url":"https://doi.org/10.1002/adma.202519692","authors":["Song X","Niu P","Gu W","Chan CLC","Yi J","Liu X","Tan P","Cheong CIH","Guan Q","Fang D","Zhou B","Wu ZL"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/adma.202519692","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"doi:10.1177/09226028261423567","name":"Low-cost Devices for Stroke Rehabilitation: A Review of Approaches, Designs, and Evidence.","source":"pubmed","abstract":"Rehabilitation devices are technologies that can automate repetitive features of therapy using force generation elements like motors to render training forces or gamified environments to improve user engagement ( e.g., rehabilitation robots). These devices have received considerable attention from researchers and clinicians over the past several decades as a means to increase dosage of intensive rehabilitation following a stroke. However, the commercial results of these efforts often manifest as highly motorized, expensive, and bulky devices that are unsuitable for the majority of clinical or home environments. Indeed, as access to rehabilitation resources begins to reveal itself as a critical obstacle to recovery for many stroke survivors, it is important for researchers to examine alternative approaches to facilitate device adoption. A handful of researchers have attempted to bridge this gap with increasing success by designing affordable and portable devices for post-stroke rehabilitation. However, the methods employed to lower device cost are quite varied; therefore, a synthesis of these approaches could benefit other researchers. In this review, we discussed the field of rehabilitation robots and provided a review of 37 existing low-cost devices for stroke rehabilitation. These devices engage patients using a variety of actuation methods to produce training forces: Active (controllable actuator that adds or dissipates energy e.g., motors, stimulators), Passive (uncontrollable actuator that only dissipates energy e.g., springs, cables), Semi-Passive (controllable actuator that only dissipates energy e.g., brakes) and Augmented Feedback (no actuator). Following this review, we outline certain unexplored areas of low-cost devices that may be fruitful areas of future exploration.","url":"https://doi.org/10.1177/09226028261423567","authors":["Augenstein TE","Krishnan

Biomimetic Manta Ray Robots: A Comprehensive Review Based on Operational Depth Spectrum, Structures, Energy Optimization, and Control Systems.","source":"europepmc","abstract":"As deep-sea exploration transitions from large-scale search to precision pinpoint operations, the inherent limitations of traditional \"rigid-body and propeller\" vehicles-specifically in low-speed maneuverability, environmental compliance, and acoustic stealth-are becoming increasingly apparent. Leveraging its unique integrated \"gliding-flapping\" locomotion and exceptional maneuverability, the manta ray serves as an ideal biological prototype for next-generation deep-sea operational platforms. From a systems engineering perspective, this paper provides a comprehensive review of the current research status and technical evolution of biomimetic manta ray submersibles. First, a technical pedigree centered on \"operational depth\" is established, illustrating how design paradigms transition from \"mechanism replication\" in shallow waters to \"pressure adaptation\" at full-ocean depths. Second, the mechanical challenges in structural design are explored, demonstrating that a \"rigid-flexible\" gradient distribution strategy is critical to resolving the conflict between pressure resistance and propulsive compliance. Regarding energy and propulsion, the synergistic effects of hybrid gliding-flapping drives and integrated structural batteries in enhancing long-range endurance and energy efficiency are analyzed. Finally, the evolution of motion control architectures-transitioning from spinal-cord-inspired Central Pattern Generator (CPG) rhythmic control to Deep Reinforcement Learning (DRL) featuring embodied intelligence-is outlined.","url":"https://doi.org/10.3390/biomimetics11030216","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/biomimetics11030216","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/biomimetics10080510","name":"Bioinspired Hierarchical Soft Gripper with Hexagonal and Suction Interfaces for Strain-Guided Object Handling.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10080510","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10080510","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s24216837","name":"Adaptive Fault-Tolerant Tracking Control for Multi-Joint Robot Manipulators via Neural Network-Based Synchronization.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s24216837","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24216837","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.3390/s26020355","name":"Research on Control Strategy of Lower Limb Exoskeleton Robots: A Review.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26020355","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26020355","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.3390/s25061919","name":"Development and In-Field Validation of an Autonomous Soil Mechanical Resistance Sensor.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25061919","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25061919","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.3389/frobt.2025.1658613","name":"Editorial: Advancing soft, tactile, and haptic technologies: recent developments for healthcare applications.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1658613","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1658613","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:51.650Z"},{"id":"doi:10.3389/frobt.2025.1665267","name":"A learning based impedance control strategy implemented on a soft prosthetic wrist in joint-space.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1665267","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1665267","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.3390/s24237465","name":"Identification of Intrinsic Friction and Torque Ripple for a Robotic Joint with Integrated Torque Sensors with Application to Wheel-Bearing Characterization.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s24237465","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24237465","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.34133/cbsystems.0233","name":"Yeast-Driven and Bioimpedance-Sensitive Biohybrid Soft Robots.","source":"pubmed","abstract":"Biohybrid robots integrate biological components with synthetic materials to harness the unique capabilities of living systems for robotic functions.

potentially grown due to the development of sophisticated mechatronic systems. One of the most important is the bio-inspired mobile-planetary robots, actually for which there is no reported one that currently works physically on the Moon. Nonetheless, significant progress has been made to design biomimetic systems based on animal morphology adapted to sand (granular material) to test them in analog planetary environments, such as regolith simulants. Biomimetics and bio-inspired attributes contribute significantly to advancements across various industries by incorporating features from biological organisms, including autonomy, intelligence, adaptability, energy efficiency, self-repair, robustness, lightweight construction, and digging capabilities-all crucial for space systems. This study includes a scoping review, as of July 2024, focused on the design of animal-inspired robotic hardware for planetary exploration, supported by a bibliometric analysis of 482 papers indexed in Scopus. It also involves the classification and comparison of limbed and limbless animal-inspired robotic systems adapted for movement in soil and sand (locomotion methods such as grabbing-pushing, wriggling, undulating, and rolling) where the most published robots are inspired by worms, moles, snakes, lizards, crabs, and spiders. As a result of this research, this work presents a pioneering methodology for designing bio-inspired robots, justifying the application of biological morphologies for subsurface or surface lunar exploration. By highlighting the technical features of actuators, sensors, and mechanisms, this approach demonstrates the potential for advancing space robotics, by designing biomechatronic systems that mimic animal characteristics.","url":"https://doi.org/10.3390/biomimetics9110693","authors":["Cornejo J","García Cena CE","Baca J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/biomimetics9110693","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:19.861Z"},{"id":"doi:10.1177/02783649251364287","name":"Configuration identification of on-demand variable stiffness strain-limiting layers in zig-zag soft pneumatic actuators using deep learning methods.","source":"pubmed","abstract":"Soft pneumatic actuators (SPAs) typically offer a fixed trajectory, resulting in one specific tip motion for a given range of pressure. When multiple trajectories are needed, these actuators require re-fabrication with altered structural designs, with different lengths, chamber sizes, and wall thicknesses etc. Passive modular variable stiffness SPAs present a significant advantage by enabling the realization of many distinct trajectories without structural redesign. Although various mathematical modeling techniques are widely used to predict their tip motion by treating it a kinematics problem, solving the inverse problem in the presence of modular strain-limiting layer (SLL) configurations is challenging. It is essential to determine the configuration of such a slender actuator in the form of a robot manipulator to deploy it for a specific function and application without re-fabricating them, by simply varying the SLL per the configuration required for a particular tip-point trajectory. To this aim, this paper introduces a hybrid methodology (based on feed-forward neural network) and a convolutional neural network-based method to predict the required SLL configuration for a particular tip trajectory of the SPA. This methodology is generic enough to apply to such actuators to predict their configuration as per their specific tip point trajectory in Cartesian space. The results presented for a slender SPA have demonstrated that the proposed method has predicted its configurations for a range of applications typified by an endoscope prototype, a soft robotic gripping application, and a system mimicking human finger movement with an average error of 1.65%. This study offers a versatile methodology for \"function and application specific\" SPAs or robot manipulators without re-fabricating them, by strategically combining SLL and machine learning-based prediction to generate a specific trajectory.","url":"https://doi.org/10.1177/02783649251364287","authors":["Gunawardane PDSH","Lee D","Cheung P","Zhou H","Alici G","Chiao M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1177/02783649251364287","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.1038/s41598-024-77100-7","name":"Optimizing actual PID control for walking quadruped soft robots using genetic algorithms.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-024-77100-7","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1038/s41598-024-77100-7","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3390/biomimetics10070423","name":"Design of Adaptive LQR Control Based on Improved Grey Wolf Optimization for Prosthetic Hand.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10070423","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10070423","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3390/biomimetics11010030","name":"Bioinspired Design for Space Robots: Enhancing Exploration Capability and Intelligence.","source":"europepmc","abstract":"Space exploration is a major global focus, advancing knowledge and exploiting new resources beyond Earth. Bioinspired design-drawing principles from nature-offers systematic pathways to increase the capability and intelligence of space robots. Prior reviews have emphasized on-orbit manipulators or lunar rovers, while a comprehensive treatment across application domains has been limited. This review synthesizes bioinspired capability and intelligence for space exploration under varied environmental constraints. We highlight four domains: adhesion and grasping for on-orbit servicing; terrain-adaptive mobility on granular and rocky surfaces; exploration intelligence that couples animal-like sensing with decision strategies; and design methodologies for translating biological functions into robotic implementations. Representative applications include gecko-like dry adhesives for debris capture, beetle-inspired climbers for truss operations, sand-moving quadrupeds and mole-inspired burrowers for granular regolith access, and insect flapping-wing robots for flight under Martian conditions. By linking biological analogues to quantitative performance metrics, this review highlights how bioinspired strategies can significantly improve on-orbit inspection, planetary mobility, subsurface access, and autonomous decision-making.

However, prior studies and surveys have primarily emphasized backbone architectures, action decoders, training recipes, and benchmark performance, whereas relatively limited systematic attention has been given to sensor modality selection, heterogeneous signal alignment and fusion, and their connection to action generation, all of which are critical to the performance and safety of real-world robotic manipulation. This survey addresses this gap by reinterpreting VLA within the framework of a sensor-fusion-action pipeline. This study first presents a systematic taxonomy of major sensor modalities, including RGB, depth, tactile sensing, force/torque, proprioception and inertial measurement unit, multi-spectral/thermal, and event-based vision, and compares them in terms of the physical information they provide, their characteristic failure modes, and their deployment constraints. This survey further reviews teleoperation-, human video-, and simulation-based data collection pipelines, together with representative dataset configurations, and analyzes the multi-modal design space from a sensor-centric perspective, including early and late fusion, cross-attention, token-level fusion, adapters, mixture of experts, and multi-rate action representations. In addition, this study identifies a strong bias in existing benchmarks toward RGB-centric inputs and single success-rate metrics and emphasizes the need for a multidimensional evaluation framework incorporating robustness, worst-case performance, safety, latency, and efficiency. By shifting the focus away from a model-centric narrative and explicitly accounting for real-world sensor complexity, this survey seeks to establish a sensor-centered foundation for the next generation of Physical AI.","url":"https://doi.org/10.3390/s26113541","authors":["Ko BC"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26113541","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.3389/frobt.2025.1528266","name":"OpenSEA: a 3D printed planetary gear series elastic actuator for a compliant elbow joint exoskeleton.","source":"europepmc","abstract":"Introduction Next-generation assistive robotics rely on series elastic actuators (SEA) that enable compliant human-robot interaction. However, currently there is a deficiency of openly available SEA systems to support this development. To address this, we propose a novel design of a compliant 3D-printed SEA device for elbow movement rehabilitation exoskeletons that we make openly available. Methods We designed a 3D-printed SEA to incorporate a planetary gear system and torsional spring, offering compliance, adaptability, and cost-effectiveness. The design provides a high-power density, that can address torque limitations in 3D printed SEA systems. Our design utilizes a 4.12 Nm motor operating at 26 RPM based on assessment of functional performance differences across healthy and post-stroke individuals. Moreover, the design of this SEA allows for easily adjustable parameters to fit different joints, or various torque output configurations, in low-cost exoskeleton applications in rehabilitation. Results Testing demonstrated an average compliance contribution of the planetary gear and the average total system compliance of 14.80° and 22.22°, respectively. This range conforms to those expected in human-exoskeleton interaction. Similarly, an FEA analysis of the 3D printed system shows stress ranges of the SEA gears to be between 50 and 60.2 MPa, which causes a displacement of approximately 0.14 mm. This is within the operational flexural range of standard 3D printed materials such as PLA, which is 175 MPa. Discussion The study demonstrates an openly available SEA design for 3D printed exoskeletons. This work provides an entry point for accessible exoskeleton design, specifically for rehabilitation. Future work will explore the role of segment vs joint rigidity in developing next-generation compliant exoskeletons, and improving accessibility for personalizable assistive exoskeletons.

However, developing an efficient and robust pollination system that integrates perception, decision-making, and execution within real-world scenarios remains confronted with complex challenges. This study systematically reviews recent advancements in the field and distills the core technical issues of greenhouse robotic pollination into three primary domains: target detection and pose estimation, end-effector design, and pollination strategies combined with motion control. Focusing on the visual perception of flowers, actuator architecture, and operational tactics, this review synthesizes existing academic findings to evaluate the state-of-the-art in flower detection and pose estimation, characterize diverse end-effector designs, and analyze the evolutionary trajectory of motion control techniques. Specifically, the analysis encompasses the impact of detection algorithms on recognition accuracy and robustness, the structural classification and performance attributes of pollination mechanisms, and the optimization of control strategies. Furthermore, the study categorizes global research backgrounds, technical methodologies, and paradigmatic system cases, offering a critical evaluation of experiences in constructing automated pollination systems. Despite these advances, current robotic pollination technologies for peppers (chili) face significant bottlenecks characterized by immature methods for precise flower detection and pose estimation, the need for optimized specialized end-effector designs, and insufficient robustness in decision-making systems under dynamic environmental conditions. To address these issues, future development should prioritize constructing diverse, large-scale flower image and pose datasets while developing detection algorithms adaptable to complex environments to achieve high-precision identification. Additionally, implementing this system requires a hierarchical architecture where perception drives adaptive actuation. Deep learning models must localize flower targets and assess maturity in real-time, feeding coordinates to path planners that generate collision-free trajectories through foliage. These trajectories are executed via multimodal motion control, synchronizing the rigid manipulator with soft end-effectors. By embedding tactile feedback into the machine learning loop, the system creates a unified sensorimotor framework. This enables dynamic force modulation based on physical resistance, ensuring precise, non-destructive pollination tailored to chili plants.","url":"https://doi.org/10.3389/fpls.2026.1778541","authors":["Kuang M","Li X","Xie F","Zou X","Xiang Y","Zhang Y","Liu D","Minqiu Kuang","Xiaojian Li","Fangping Xie","Xuejie Zou","Yang Xiang"],"tags":["Pollination","Robustness (evolution)","Greenhouse","Computer science","Artificial intelligence"],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/fpls.2026.1778541","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"doi:10.3389/frobt.2024.1517037","name":"Erratum: Novel bio-inspired soft actuators for upper-limb exoskeletons: design, fabrication and feasibility study.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2024.1517037","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1517037","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3390/biomimetics11010041","name":"Navigation and Load Adaptability of a Flatworm-Inspired Soft Robot Actuated by Staggered Magnetization Structure.","source":"pubmed","abstract":"This study presents a magnetically actuated soft robot inspired by the peristaltic locomotion of flatworms, designed to replicate the biological locomotion of worms to achieve robust maneuverability.

By applying a vertically oscillating magnetic field, the robot achieves forward crawling through the coordinated bending and lifting of fins, converting oscillating magnetic fields into continuous undulatory motion that mimics the gait of flatworms. The experimental results demonstrate that the system maintains consistent bidirectional velocities in the range of 4-7 mm/s on flat surfaces. Beyond linear locomotion, the robot demonstrates effective terrain adaptability, navigating complex topographies, including curved obstacles up to 16 times its body thickness, by autonomously adopting a high-lifting kinematic strategy to overcome gravitational resistance.

Provide the process of the mechanism, and establish a kinematic model of the mechanism. In order to improve the motion performances of the cam-elliptical gear combined labeling mechanism and avoid labels damage, the NSGA-II algorithm is used to optimize the parameters of the mechanism, resulting in 80 sets of Pareto solutions. The entropy weight TOPSIS method is applied as a quadratic optimization to select an optimal solution from the 80 sets of Pareto solutions and obtain the optimized parameters of the mechanism. A comparative study is conducted with an elliptical-circular planetary gear mechanism using the hypocycloid trajectory. The results show that the improved mechanism reduces the maximum velocity by 7%, the maximum and minimum accelerations by 2% and 18%. After the quadratic optimization the distance error of the center point of suction cup and the labeling point is reduced from 1.3 mm to 0.12 mm, and the velocity during labeling and taking position is reduced from 0.10770 m s -1 to 0.0037 m s -1 . The correctness of the proposed method is validated through simulation studies and experiments. This research provides a theoretical basis for the design and optimization of long label and curved surface labeling mechanism for vegetables.","url":"https://doi.org/10.3389/frobt.2024.1431078","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1431078","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3389/frobt.2024.1451231","name":"Novel bio-inspired soft actuators for upper-limb exoskeletons: design, fabrication and feasibility study.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2024.1451231","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1451231","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.1126/scirobotics.adn2733","name":"Understanding the sense of self through robotics.","source":"pubmed","abstract":"Robotics can play a useful role in the scientific understanding of the sense of self, both through the construction of embodied models of the self and through the use of robots as experimental probes to explore the human self. In both cases, the embodiment of the robot allows us to devise and test hypotheses about the nature of the self, with regard to its development, its manifestation in behavior, and the diversity of selves in humans, animals, and, potentially, machines. This paper reviews robotics research that addresses the topic of the self-the minimal self, the extended self, and disorders of the self-and highlights future directions and open challenges in understanding the self through constructing its components in artificial systems. An emerging view is that key phenomena of the self can be generated in robots with suitably configured sensor and actuator systems and a layered cognitive architecture involving networks of predictive

imitation learning for dexterous robotic manipulation: challenges and perspectives-a survey.","source":"europepmc","abstract":"Dexterous manipulation is a crucial yet highly complex challenge in humanoid robotics, demanding precise, adaptable, and sample-efficient learning methods. As humanoid robots are usually designed to operate in human-centric environments and interact with everyday objects, mastering dexterous manipulation is critical for real-world deployment. Traditional approaches, such as reinforcement learning and imitation learning, have made significant strides, but they often struggle due to the unique challenges of real-world dexterous manipulation, including high-dimensional control, limited training data, and covariate shift. This survey provides a comprehensive overview of these challenges and reviews existing learning-based methods for real-world dexterous manipulation, spanning imitation learning, reinforcement learning, and hybrid approaches. A promising yet underexplored direction is interactive imitation learning, where human feedback actively refines a robot's behavior during training. While interactive imitation learning has shown success in various robotic tasks, its application to dexterous manipulation remains limited. To address this gap, we examine current interactive imitation learning techniques applied to other robotic tasks and discuss how these methods can be adapted to enhance dexterous manipulation. By synthesizing state-of-the-art research, this paper highlights key challenges, identifies gaps in current methodologies, and outlines potential directions for leveraging interactive imitation learning to improve dexterous robotic skills.","url":"https://doi.org/10.3389/frobt.2025.1682437","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1682437","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3389/frobt.2025.1592523","name":"A model-based approach to automation of formal verification of ROS 2-based systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1592523","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1592523","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3389/fpls.2026.1805450","name":"Dynamic analysis and driving performance verification of multi-functional electric tracked vehicles for greenhouses in hilly and mountainous areas.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/fpls.2026.1805450","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/fpls.2026.1805450","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3389/frobt.2025.1612392","name":"Adaptive emergency response and dynamic crowd navigation for mobile robot using deep reinforcement learning.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1612392","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1612392","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.3390/biomimetics10070466","name":"Biomimetic Robotics and Sensing for Healthcare Applications and Rehabilitation: A Systematic Review.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10070466","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10070466","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.1002/rcs.70015","name":"Towards Design and Development of an MRI Conditional Robot to Enable Curvilinear Transperineal Prostate Biopsy.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/rcs.70015","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1002/rcs.70015","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.1021/acsami.4c11296","name":"Self-Repairable Carbon Fiber-Reinforced Epoxy Vitrimer Actuator with Multistimulus Responses and Programmable Morphing.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsami.4c11296","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1021/acsami.4c11296","addedAt":"2026-08-31T06:34:11.996Z","updatedAt":"2026-08-31T06:34:13.659Z"},{"id":"doi:10.5281/zenodo.15294020","name":"RoboRoyale software for the robotic observation and interaction system","source":"datacite","abstract":"Introduction The presented software is part of the Autonomous Robotic Observation and Behavioral Analysis System, complemented with interaction modules.

This robot can swim at speeds of up to 18.7 mm/s (0.46 Bl/s) and is the first subgram microswimmer with onboard power, actuation, and computation developed to date. Unfortunately, the approach employed to actuate VLEIBot++ prototypes is infeasible for underwater applications because a typical 10-mg bare SMA-based microactuator requires an average power on the order of 800 mW when operating underwater. To address this issue, we introduce a new 13-mg power-efficient high-performance SMA-based microactuator that can function with similar power requirements (approx. 80 mW on average) and actuation performance (approx. 3 mm at low frequencies) in air and water. This design is based on the use of a sealed flexible air-capsule that encloses the SMA wires that drive the microactuator with the purpose of passively controlling the heat-transfer rate of the thermal system. Furthermore, this new power-efficient encapsulated actuator requires low voltages of excitation (3 to 4 V) and simple power electronics to function. The breakthroughs presented in this paper represent a path towards the creation of insect-scale autonomous underwater vehicles (AUVs).","url":"https://doi.org/10.48550/arxiv.2411.18001","authors":["Longwell, Cody R.","Trygstad, Conor K.","Perez-Arancibia, Nestor O."],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.48550/arxiv.2411.18001","addedAt":"2026-08-31T06:34:11.997Z","updatedAt":"2026-08-31T06:34:11.997Z"},{"id":"doi:10.18154/rwth-2024-12329","name":"Towards enhanced rehabilitation: modeling and control of lower limb exoskeletons for human-robot cooperation and fatigue management","source":"datacite","abstract":"The marvel of human walking is a complex combination of intricate control strategies, but it can be disrupted by injuries and illnesses such as strokes. The prevalence of the resulting gait disorders remains an acute global health challenge affecting millions of people. Early and intensive rehabilitation is crucial for recovery. Traditional rehabilitation methods require significant financial and human resources, leading to an increased interest in rehabilitation robotics. In addition, aging demographics will increase the need for home-based care, increasing the need for rehabilitation robotics and ultimately promoting greater autonomy for individuals. For optimal rehabilitation outcomes, it is important that patients actively initiate movements themselves, as this kind of motor learning is crucial for stimulating neuroplasticity. Exoskeletons that prioritize patient-initiated actions and adapt in real-time to user intent could benefit clinical and everyday settings. The realization requires precise sensing of movement intention and utilizing advanced control strategies to support the patient's movement while prioritizing safety through hardware and software solutions. The goal of this dissertation is to explore design and control methods of lower limb exoskeletons to enhance robot-assisted rehabilitation. The investigated approach designates the user as the central controller, underscoring the robot's role in responding to, rather than dictating, human movements. Additionally, this thesis examines the potential of exoskeletons as both a diagnostic and intervention tool for muscle fatigue - a prevalent and debilitating symptom among individuals with gait disorders. The first task of this thesis describes the hardware design of a new active lower-limb exoskeleton based on variable stiffness actuators for hip and knee assistance to ensure a safe human-exoskeleton coupling. By estimating the user's joint torque in real-time through a coupled human-exoskeleton model for both swing and stance phases, a novel human-cooperative controller is developed to augment user movement. The control strategy is validated on the newly designed exoskeleton. Additionally, a control concept for the varying serial elasticity is proposed to combine the advantageous high bandwidth of a stiff actuator with the patient safety advantage of a compliant actuator in response to patient motion. For examination of the exoskeleton’s potential to function as a diagnostic tool for muscle fatigue, a fatigue model is formulated and parameterized based on a study involving healthy participants. Lastly, the feasibility of modulating the exoskeleton's assistance according to the fatigue level is investigated.","url":"https://doi.org/10.18154/rwth-2024-12329","authors":["Bergmann, Lukas Manuel"],"tags":["Hochschulschrift","exoskeletons ; rehabilitation robotics ; movement intention ; modeling ; control ; fatigue ; Exoskelette ; Bewegungsintention ; Modellierung ; Regelung ; Ermüdung"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.18154/rwth-2024-12329","addedAt":"2026-08-31T06:34:11.997Z","updatedAt":"2026-08-31T06:34:11.997Z"},{"id":"doi:10.48550/arxiv.2410.06008","name":"Sitting, Standing and Walking Control of the Series-Parallel Hybrid Recupera-Reha Exoskeleton","source":"datacite","abstract":"This paper presents advancements in the functionalities of the Recupera-Reha lower extremity exoskeleton robot.

One of the most popular locomotion gaits that has been implemented in soft robots is undulation. The undulation motion in soft robots resembles the locomotion gait of stringy creatures such as snakes, eels, and C. Elegans. Typically, the implementation of undulation locomotion on a soft robot requires many actuators to control each segment of the stringy body. The added weight of multiple actuators limits the navigating performance of soft-bodied robots. In this paper, we propose a simple tendon-driven flexible beam with only one actuator (a DC motor) that can generate a mechanical traveling wave along the beam to support the undulation locomotion of soft robots. The beam will be precompressed along its axis by shortening the length of the two tendons to form an S-shape, thus pretensioning the tendons. The motor will wind and unwind the tendons to deform the flexible beam and generate traveling waves along the body of the robot. We experiment with different pre-tension to characterize the relationship between tendon pre-tension forces and the DC-motor winding/unwinding.

Advances in the field of teletaction for teleoperation however, have yet to make full use of the high-resolution 3D data provided by modern vision-based tactile sensors. Existing solutions for teletaction lack in one or more areas of form or function, such as fidelity or hardware footprint. In this paper, we showcase our design for a low-cost teletaction device that can utilize real-time high-resolution tactile information from vision-based tactile sensors, through both physical 3D surface reconstruction and shear displacement. We present our device, the Feelit, which uses a combination of a pin-based shape display and compliant mechanisms to accomplish this task. The pin-based shape display utilizes an array of 24 servomotors with miniature Bowden cables, giving the device a resolution of 6x4 pins in a 15x10 mm display footprint. Each pin can actuate up to 3 mm in 200 ms, while providing 80 N of force and 1.5 um of depth resolution. Shear displacement and rotation is achieved using a compliant mechanism design, allowing a minimum of 1 mm displacement laterally and 10 degrees of rotation. This real-time 3D tactile reconstruction is achieved with the use of a vision-based tactile sensor, the GelSight [1], along with an algorithm that samples the depth data and marker tracking to generate actuator commands.

The characterization was conducted to determine the influence of the thickness, length, input frequency, drive voltage and orientation angle on the tip force and output frequency. The results show that IPMC thickness has significant influence on the tip force generation and lower input frequency would results wider displacement.

The actuator itself is a complex nonlinear system whose performance can be characterized by the speed and torque capabilities of its motor, and its accuracy depends on the resolution of the encoder as well as its ability to resist deformations under load. The mechanical gain associated with the transmission is critical to the overall performance of the actuator since it amplifies the motor torque, thus improving the force capability of the manipulator housing it, reduces the motor speed to a suitable output speed operating range, and amplifies the stiffness improving the precision under load of the overall system. In this work, a basic analytic process that can be used to manage the actuator gain parameter to obtain an improved arm design based on a set of desired/required performance specifications will be laid out. Key to this analytic process is the mapping of the actuator parameters (speed, torque, stiffness, and encoder resolution) to their effective values at the system output via the mechanical gains of the actuators as well as the effective mechanical gains of the manipulator. This forward mapping of the actuator parameters allows the designer to determine how each of the parameters influences the functional capacity of the serial manipulator arm. The actuator gains are then distributed along the effective length of the manipulator to determine their effects on the performance capabilities of the system. The analytic formulation is also demonstrated to be effective in addressing the issue of configuration management of serial robotic manipulators where the goal is to assemble a system that meets some required performance specifications. To this end, two examples demonstrating a solution of the configuration management problem are presented. The analytic process developed based on the mapping of the mechanical parameters of the actuator to their effective values at the system output is shown to dramatically reduce the effort in the initial phases of the design process, meaning that the number of design iterations can be dramatically reduced.","url":"https://doi.org/10.1115/1.3066625","authors":["Oziel Rios","Delbert Tesar"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-01-21T23:26:39Z","doi":"10.1115/1.3066625","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:16.555Z"},{"id":"doi:10.23919/ccc52363.2021.9550388","name":"Sliding Mode Control for Robot Manipulators with Actuator Faults","source":"crossref","abstract":"","url":"https://doi.org/10.23919/ccc52363.2021.9550388","authors":["Zhibo Lian","Junyong Zhai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-10-07T04:24:31Z","doi":"10.23919/ccc52363.2021.9550388","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:16.555Z"},{"id":"doi:10.1049/cp:20040271","name":"Development of a new actuator for a small biped walking entertainment robot","source":"crossref","abstract":"","url":"https://doi.org/10.1049/cp:20040271","authors":["T.

A typical treatment procedure includes access preparation (opening crown with drills), root canal shaping and cleaning, and then root canal filling. This treatment is expensive, time-consuming, and prone to human error. The outcome relies on the clinician’s skill, which is gained through years of training and practice. The success quotient of this treatment is 60–65% for general dentists and 90% for specialists (endodontists). Therefore, an Advanced Endodontic Technology Development project was initiated. The goal of this project is to develop an intelligent micro robot and a computer aided treatment system to execute the endodontic treatment automatically. It is expected that this intelligent micro robot system will overcome the problems encountered in current treatment practice and increase the treatment accuracy and efficiency. This paper briefly describes the Advanced Endodontic Technology Development project followed by the design of the micro robot for the root canal treatment. The paper focuses on the design of the Z axis actuator to control the treatment tool’s motion and quick tool change assembly in the micro robot.","url":"https://doi.org/10.1115/imece2010-40816","authors":["Janet Dong","Shane Y.

The RBFNN was adopted to achieve on-line estimation for the dynamics nonlinear uncertain part for follower and leader robots. The adaptive robust controller was adopted to compensate modeling errors of neural network. This strategy not only solved the problem of parameters and non-parameter uncertainties of mobile robots, but also ensured the desired trajectory tracking of robot formation in the case of maintaining formation. The stability and convergence of the control system were proved by using the Lyapunov theory.

Experiments are carried out on the prototype of a novel quadruped robot and the results show that this method is effective for analysis of fault tolerance of quadruped robots.","url":"https://doi.org/10.1115/1.4028151","authors":["Jing Wang","Feng Gao","Yong Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-08-04T18:54:44Z","doi":"10.1115/1.4028151","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1299/jsmemecj.2017.g1600102","name":"Fabrication of PZT thin film actuator for Insect scale robot","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmemecj.2017.g1600102","authors":["Nozomu NISHIMURA","Hirotaka HIDA","Isaku KANNO"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-03-25T22:36:56Z","doi":"10.1299/jsmemecj.2017.g1600102","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1016/j.ifacol.2020.12.2707","name":"Globally Asymptotic Output Feedback Tracking of Robot Manipulators With Actuator Constraints","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.ifacol.2020.12.2707","authors":["Yuxin Su","Chunhong Zheng","Paolo Mercorelli"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-04-15T22:14:31Z","doi":"10.1016/j.ifacol.2020.12.2707","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/icra40945.2020.9196823","name":"Single Actuator Peristaltic Robot for Subsurface Exploration and Device Emplacement","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra40945.2020.9196823","authors":["Juan De la Fuente","Roman Shor","Steve Larter"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-09-15T21:25:46Z","doi":"10.1109/icra40945.2020.9196823","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/icra.2013.6630649","name":"Closed-loop commutation control of an MRI-powered robot actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2013.6630649","authors":["Christos Bergeles","Panagiotis Vartholomeos","Lei Qin","Pierre E.

Robotics is one of the areas that have benefited a lot from these advancements. Many important and useful applications for single-robot and multi-robot systems (MRS) have emerged. Such applications include search and rescue, detection of forest fires, mining, construction, disaster management, and many more. MRS systems greatly enhance the capabilities and effectiveness of today’s robots. They extend the robotic system capabilities by increasing the ability to perform more complex tasks and allow performance of inherently distributed ones. In addition, they increase parallelism, enhance robustness, and improve system reliability. However, to perform their tasks in an effective manner, communication between the individual robots becomes an essential component. In this paper, we discuss the various types and architectures of MRS systems and focus on the networking issues, and services that are required to enable MRS systems to be more efficient in performing their roles in their respective applications. We also identify the similarities and differences between mobile ad hoc networks (MANETs) and MRS systems, analyze robot-to-robot (R2R) and robot-to-infrastructure (R2I) communication links, and identify the protocols that can be used at the various levels in the MRS hierarchy.","url":"https://doi.org/10.3390/jsan7040052","authors":["Imad Jawhar","Nader Mohamed","Jie Wu","Jameela Al-Jaroodi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-11-30T12:13:17Z","doi":"10.3390/jsan7040052","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.14736/kyb-2021-1-0160","name":"Observer-based adaptive sliding mode fault-tolerant control for the underactuated space robot with joint actuator gain faults","source":"crossref","abstract":"","url":"https://doi.org/10.14736/kyb-2021-1-0160","authors":["Ronghua Lei","Li Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-03-05T14:58:41Z","doi":"10.14736/kyb-2021-1-0160","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/aim52237.2022.9863370","name":"Design of a Soft Rat Robot Based on Pneumatic Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim52237.2022.9863370","authors":["Li Yuanzhong","Atsuo Takanishi","Hiroyuki Ishii"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-08-25T19:39:30Z","doi":"10.1109/aim52237.2022.9863370","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/oceansap.2016.7485555","name":"A new concept spherical underwater robot propelled by thrust vector synthetic jet actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/oceansap.2016.7485555","authors":["Lingbo Geng","Yang Lin","Zhiqiang Hu","Chao Wang","Lingshuai Meng","Dongdong Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-06-23T16:52:27Z","doi":"10.1109/oceansap.2016.7485555","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/icma.2019.8816448","name":"Adaptive Sliding Control for Lower Exoskeleton Robot Driven by The Series Elastic Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icma.2019.8816448","authors":["Shuqiao Chen","Jianghai Zhao","Zhipeng Yu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-08-29T21:00:10Z","doi":"10.1109/icma.2019.8816448","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1145/3278198.3278223","name":"A Novel Soft Actuator for Continuum Soft Robot Arm","source":"crossref","abstract":"","url":"https://doi.org/10.1145/3278198.3278223","authors":["Zahra S.

However, saturation is a common phenomenon in robotics leading to significant nonlinearity in system behavior. In this study, the saturation of the actuator torques is considered as a temporary reduction of the number of independent control inputs. The reduction of the number of actuators leads to an underactuated control problem which typically involves the handling of differential algebraic equation systems. The saturated system may become especially complex when intricate combinations of the actuator saturations appear. A servoconstraint-based inverse dynamics control method for underactuated multibody systems is applied for the treatment of actuator torque saturation. In case of human-friendly robots, the problem of saturation cannot be avoided on the level of trajectory planning because unexpected human perturbations may take place, which result in such abrupt changes in the desired trajectory that lead to saturation at some actuators. A case study for the service robot Acroboter shows the applicability of the proposed approach.","url":"https://doi.org/10.1115/1.4034868","authors":["Ambrus Zelei","László Bencsik","Gábor Stépán"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-10-04T22:41:43Z","doi":"10.1115/1.4034868","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1016/j.mechatronics.2017.05.008","name":"Path-tracking velocity control for robot manipulators with actuator constraints","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.mechatronics.2017.05.008","authors":["Björn Olofsson","Lars Nielsen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-06-15T19:35:26Z","doi":"10.1016/j.mechatronics.2017.05.008","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.21595/jve.2014.14948","name":"Piezoelectric actuator for micro robot used in nanosatellite","source":"crossref","abstract":"The nanosatellites of the CubeSat standard (10×10×10 cm and with mass 1-10 kg) was designed to reduce cost and development time and to maximize science return.

Pneumatic catheters offer a promising alternative to conventional steerable catheters for safe navigation through the natural pathways without tissue injury. In this work, we present an optimized 6 mm diameter two-degree-of-freedom pneumatic actuator, able to bend in every direction and incorporating a 1 mm working channel. A versatile vacuum centrifugal overmolding method capable of producing small geometries with a variety of silicones is described, and meter-long actuators are extruded industrially. An improved method for fiber reinforcement is also presented. The actuator achieves bending more than 180° and curvatures of up to 0.1 mm −1 . The exerted force remains below 100 mN, and with no rigid parts in the design, it limits the risks of damage on surrounding tissues. The response time of the actuator is below 300 ms and therefore not limited for medical applications. The working space and multi-channel actuation are also experimentally characterized. The focus is on the study of the influence of material stiffness on mechanical performances. As a rule, the softer the material, the better the energy conversion, and the stiffer the material, the larger the force developed at a given curvature. Based on the actuator, a 90 cm long steerable catheter demonstrator carrying an optical fiber is developed, and its potential for endoscopy is demonstrated in a bronchial tree phantom. In conclusion, this work contributes to the development of a toolbox of soft robotic solutions for MIS and endoscopic applications, by validating and characterizing a promising design, describing versatile and scalable fabrication methods, allowing for a better understanding of the influence of material stiffness on the actuator capabilities, and demonstrating the usability of the solution in a potential use-case.","url":"https://doi.org/10.3389/frobt.2021.768236","authors":["Gilles Decroly","Pierre Lambert","Alain Delchambre"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-11-11T10:10:34Z","doi":"10.3389/frobt.2021.768236","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1109/aim.2005.1500986","name":"A Piezoelectric Unimorph Actuator Based Precision Positioning Miniature Walking Robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim.2005.1500986","authors":["Kwon Joong Son","V.

However, the nonlinear relation between the input voltage, output strain of the actuators, and the difficulty of analytical modelling makes it hard to design its control software due to the various source of kinematic noises. Machine learning technics, however, which are invented to study the implicit relations in multiparameter problems that do not require pre-existing knowledge, are well suited for HASEL actuators. Traditionally, researchers consider the behavior of this time-dependent system as a sequence of consecutive statuses and use machine learning to enhance conventional algorithms that consume previous and current status and target and adjust the system using varying control input. However, HASEL actuators’ unique propriety of self-stable and negligible lag in response to input changing makes it possible to consider the spatial path of the structure as a whole and control it based on pattern matching. Introducing Recurrent Neural Networks (RNN) and multilayer perceptron (MLP), this paper presents a pattern-matching-based predictive control algorithm for the HASEL actuator system with acceptable size and high accuracy.","url":"https://doi.org/10.1088/1742-6596/2405/1/012026","authors":["Yuheng Dong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-12-12T15:35:47Z","doi":"10.1088/1742-6596/2405/1/012026","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.3901/jme.2013.15.028","name":"Mechanism and Impedance Control of the Ball Universal Joint Robot Driven by the Pneumatic Muscle Actuator Group","source":"crossref","abstract":"","url":"https://doi.org/10.3901/jme.2013.15.028","authors":["Yu LIU"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-12-31T09:18:58Z","doi":"10.3901/jme.2013.15.028","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/icit.2014.6894976","name":"Model based actuator fault diagnosis for a mobile robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icit.2014.6894976","authors":["George K.

on uneven and unstructured terrains, offering potential applications in inspection, search and rescue, and field exploration. However, achieving robust locomotion on low-cost platforms remains challenging because of constraints in stability, adaptability, sensing quality, and onboard computation. In this work, we present an integrated motion-control framework that combines biologically inspired Central Pattern Generators (CPGs), a multi-agent reinforcement learning coordination layer, and low-cost hardware adaptation to enable reliable and efficient quadruped locomotion. The proposed framework uses CPGs as structured gait priors for rhythmic leg motion, models each leg as a coordinated agent with a shared-parameter residual policy, and incorporates actuator abstraction and safety-aware command projection. The low-cost merit specifically concerns online deployment: the four legs share a single 39,560-parameter actor (approximately 155 KiB in 32-bit precision), evaluated at 50 Hz from compact proprioceptive observations, while the centralized critic, simulation infrastructure, external motion capture, vision-based terrain perception, direct torque sensing, and online dynamics optimization are not required on the robot. We validate the approach in both simulation and on a physical low-cost quadruped robot across obstacles, ramps, stairs, and uneven terrain. Experimental results demonstrate that the integrated system improves locomotion stability, energy efficiency, and terrain adaptability compared with baseline controllers, highlighting the effectiveness of combining a structured gait prior, lightweight residual coordination, and hardware-aware deployment for practical quadruped locomotion.","url":"https://doi.org/10.1371/journal.pone.0356505","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1371/journal.pone.0356505","addedAt":"2026-08-31T06:34:12.095Z","updatedAt":"2026-08-31T06:34:19.809Z"},{"id":"doi:10.21203/rs.3.rs-10661589/v1","name":"The Largest Robot in the World: Agentic Conversational Control of a Particle Accelerator via MCP and Digital Twin","source":"europepmc","abstract":"Abstract Modern particle accelerators are among the most complex cyber-physical systems ever built. This paper presents an AI-assisted control architecture for Elettra 2.0, a fourth-generation synchrotron light source under construction at Elettra-Sincrotrone Trieste, which conceptualises the accelerator as a large-scale robotic system. The approach integrates AI agents and Large Language Models (LLMs) with the TANGO Controls framework through a Model Context Protocol (MCP) server, letting operators interact with the machine via natural-language dialogue. The architecture is explicitly hierarchical: high-level LLM reasoning is separated from deterministic procedural execution and from real-time control loops, so that AI remains a supervisory layer rather than a direct actuator-level controller. The conversational interface is built on the Voiceflow platform, which also hosts a Retrieval-Augmented Generation (RAG) knowledge base built on the facility's document corpus. Standardised agentic skills orchestrate Sequencer devices — TANGO devices encoding Behavior Tree procedures — alongside atomic TANGO operations, covering procedures such as power management and orbit optimisation. During pre-commissioning the architecture is interfaced with a physics-based Digital Twin coupling the Accelerator Toolbox engine to a full virtual TANGO control system, enabling operator training and validation before the real machine is commissioned. On a benchmark of representative operator intents executed against the Digital Twin, the agent achieved intent-to-tool-call mapping accuracy and command success rates above 95%, at a median round-trip latency of about one second for atomic operations, with no unsafe action observed.

Immunotherapy is an emerging brain tumor treatment technique but faces challenges due to low trafficking with systemic infusions, particularly in the case of large tumors. To address this limitation, we have developed a novel robotic system capable of delivering therapeutic agents throughout the entire volume of the brain tumor. The robot consists of a straight, rigid outer tube and a flexible inner tube that can navigate along curved paths and articulate in 3D space. A custom-designed injection mechanism consisting of syringes and hydraulic transmission is integrated into the robotic system. A non-magnetic actuation system enables robot navigation to various locations within the tumor. Therefore, by delivering therapeutic agents to individual target locations, the overall trafficking and efficiency can be potentially improved. Characterization-based control experiments yielded a curvature control error of 2.6 &#xb1; 1.8% and a relative tip tracking error of 4.2 &#xb1; 3.9%, demonstrating the high accuracy of our control strategy. A phantom study demonstrated a significant improvement of the tumor coverage ratio made by the robotic needle compared to the straight needle (73% vs. 29%). An MRI-guided manipulation study showed an acceptable decrease in the signal-to-noise ratio (up to 1.41%) when the robot is manipulated in the water phantom.

To achieve controllable, shape adaptation, and programmed deforming behavior, this study proposes an integrated control strategy for an SMA-SMP based programmable morphing structure used as an actuator in soft robotics. To achieve precise control over programming deformations and stiffness variation, a multi-target thermal sensing method (MTTSM) was proposed, integrated into an interaction-driven control framework. Based on MTTSM, the coordinated actuation between the SMA springs and the SMP structure is realized, enabling standby of preheating, stepping with programmed deformations, and dynamic stiffness changes. In addition, to achieve dynamic monitoring of deformed states, the co-training-based monitoring system is developed for collaboration, enabling the use of multisensor fusion for position estimation in the absence of end-effectors that can directly measure the deformed structure of the flexible body. In conclusion, the proposed integration strategy of MTTSM and the cotraining monitoring system offers a control solution for integrating multiple shape memory materials into morphing structures as smart actuators applied to soft robotic applications.","url":"https://doi.org/10.1177/21695172261437932","authors":["Chen Q","Wu R","Zhou X","Schott D","Jovanova J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1177/21695172261437932","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:19.810Z"},{"id":"doi:10.21203/rs.3.rs-9254688/v1","name":"Build on Priors: Vision-Language-Guided Neuro-Symbolic Imitation Learning for Data-Efficient Real-World Robot Manipulation","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-9254688/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-9254688/v1","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"doi:10.21203/rs.3.rs-9802079/v1","name":"Dynamic modeling of human–exoskeleton interaction: A simulation framework for gait rehabilitation","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-9802079/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-9802079/v1","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"doi:10.1177/21695172251407827","name":"An Origami-Based Cable-Climbing Soft Robot.","source":"europepmc","abstract":"","url":"https://doi.org/10.1177/21695172251407827","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1177/21695172251407827","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:19.809Z"},{"id":"doi:10.3390/s26092719","name":"Shared-Control HMI for Tactile-First Traversal Offline Counterfactual Evaluation with Haptic Safety Projection.","source":"pubmed","abstract":"Supervising tactile-first robotic traversal in confined, uncertain spaces poses a challenge: operators must be able to intervene without continuous micromanagement.

Results show consistent improvements: predicted collisions decrease, minimum clearance increases, traversal time and path length improve, and the traversability certificate margin rises. Operator-autonomy disagreement is reduced, with smoother control and fewer heading reversals, particularly under algorithms M2 and M3. Importantly, the synthesized haptic alerts anticipate safety-critical events with positive lead time, achieving high precision and recall as objective measures of informativeness. Together, these findings indicate that shared-control blending with tactile-first autonomy can enhance safety, efficiency, and assurance while reducing conflict between operator intent and autonomy.

Commercially available quadrupedal robots are also prohibitively expensive for biological research programs and difficult to customize. Here, we present a 3D printable, low-cost quadrupedal robot with modular legs that can match a wide range of animal morphologies for biomechanical hypothesis testing. The Robot Of Theseus (TROT) costs &#x2248;$4000 to build out of 3D printed parts and standard off-the-shelf supplies. There are three main mechanisms to enhance morphological modularity: (1) each limb can consist of 3 or 4 rigid links, (2) the direction of the femur-tibia joint can be easily switched to mimic a knee or elbow, and (3) telescoping mechanisms allow users to vary the length of each limb link. The open-source software accommodates user-defined gaits and morphology changes. Effective leg length, or crouch, is determined by the four-bar linkage actuating each joint. The backdrivable motors can vary virtual spring stiffness and range of motion. Full descriptions of the TROT hardware and software are freely available online with assembly and user guides. We demonstrate the use of TROT to compare locomotion among extant, extinct, and theoretical morphologies. We found that a 29% percent increase in leg moment of inertia resulted in a 28.3% increase in cost of transport. In addition to biomechanical hypothesis testing, we envision a variety of different applications for this low-cost, modular, legged robotic platform, including developing novel control strategies, clearing land mines, or remote exploration.

These limitations fundamentally constrain the fidelity and expressiveness of tactile communication, preventing current human-machine interfaces from reproducing the broadband of sensations perceived by human skin. Here, we present a large-area bidirectional human-machine interface (HMI) that utilizes a unified haptic dual-resonant actuator (UHDRA) capable of simultaneously implementing electrostatic-based multimodal tactile sensing and actuation.

Soft pneumatic actuators, as a fundamental element in soft robotics, have gained huge popularity and are being employed for the development of soft robots. During the last decade, a variety of hyper-elastic robotic systems have been realized. As the name suggests, such robots are made up of soft materials, and do not have any underlying rigid mechanical structure. These robots are actuated employing various methods like pneumatic, electroactive, jamming etc. Generally, in order to achieve a desired mechanical response to produce required actuation or manipulation, two or more materials having different stiffness are utilized to develop a soft robot. However, this method introduces complications in the fabrication process as well as in further design flexibility and modifications. The current work presents a design scheme of a soft robotic actuator adapting an easier fabrication approach, which is economical and environment friendly as well. The purpose is the realization of a soft pneumatic actuator having functional ability to produce effective actuation, and which is further employable to develop modular and scalable mechanisms. That infers to scrutinize the profile and orientation of the internal actuation cavity and the outer shape of viii the actuator. Utilization of a single material for this actuator has been considered to make this design scheme convenient. A commercial silicone rubber was selected which served for an economical process both in terms of the cost as well as its accommodating fabrication process through molding. In order to obtain the material behavior, ?Ansys Workbench 17.1 R ? has been used. Cubic outline for the actuator aided towards the realization of a body shape which can easily be engaged for the development of modular mechanisms employing multiple units. This outer body shape further facilitates to achieve the stability and portability of the actuator. The soft actuator has been named ?Soft Cubic Module? based on its external cubic shape. For the internal actuation cavity design, various shapes, such as spherical, elliptical and cylindrical, were examined considering their different sizes and orientations within the cubic module. These internal cavities were simulated in order to achieve single degree of freedom actuation. That means, only one face of the cube is principally required to produce effective deformation. ?Creo Perametric 3.0 M 130? has been used to design the model and to evaluate the performance of actuation cavities in terms of effective deformation and the resulting von-mises stress. Out of the simulated profiles, cylindrical cavity with desired outcomes has been further considered to design the soft actuator. ?Ansys Workbench 17.1 R ? environment was further used to assess the performance of cylindrical actuation cavity. Evaluation in two different simulation environments helped to validate the initially achieved results. The developed soft cubic actuator was then employed to develop different mechanisms in a single unit configuration as well as multi-unit robotic system developments. This design scheme is considered as the first tool to investigate its capacity to perform certain given tasks in various configurations. Alongside its application as a single unit gripper and a two unit bio-mimetic crawling mechanism, this soft actuator has been employed to realize a four degree ix of freedom robotic mechanism. The formation of this primitive soft robotic four axis mechanism is being further considered to develop an equivalent mechanism similar to the well known Stewart platform, with advantages of compactness, simpler kinematics design, easier control, and lesser cost. Overall, the accomplished results indicate that the design scheme of Soft Cubic Module is helpful in realizing a simple and cost-effective soft pneumatic actuator which is modular and scalable.

Despite of the importance of a high success rate, the conventional PIVC operation suffers from low insertion accuracy especially on young pediatric patients. On average, each pediatric patient is submitted to 2.1 attempts before venous access is obtained, with around 50% failure for the first attempt. The risks of such multiple attempts can be severe and life-threatening as they can cause serious extravasation injuries. Given the levels of precision and controllability needed for PIVC, robotic systems show a good potential to effectively assist the operation and improve its success rate. Therefore, this study aims to provide such robotic assistance by focusing on the most challenging and error-prone parts of the operation. In order to understand the difficulties of a pediatric PIVC, a survey investigation is conducted with specialists at the beginning of this research. The feedbacks from this survey indicates an urgent need of a hand-held robot to assist in the catheter insertion control to precisely access the target vein. To achieve the above goal, a novel venipuncture detection system based on sensing the electrical impedance of the contacting tissue at the needle tip has been proposed and developed. Then several ex-vivo and in-vivo experiments were conducted to assess this detection system. Experimental results show that this system can be highly effective to detect venipuncture. Subsequently, based on this venipuncture detection system, four different handheld robots have been developed to provide different levels of autonomy and assistance while executing a PIVC insertion: 1. SVEI, short for ?Smart Venous Enter Indicator?, is the simplest device without actuation. The user needs to do the whole PIVC operation, and this device only provides an indication of venipuncture by lighting up an LED. 5 2. SAID, short for ?Semi-Autonomous Intravenous access Device?, integrates a motor to control the catheter insertion. The user is required to hold the device still and target it to a vein site. He/She then activates the device. The device inserts the catheter automatically and stops it when venipuncture is detected. 3. SDOP, short for ?Smart hand-held Device for Over-puncture Prevention?, integrates a latch-based disengage mechanism to prevent over-puncture during PIVC. The user can keep the conventional way of operation and do the insertion manually. At the moment of venipuncture, the device automatically activates the disengage mechanism to stop further advancement of the catheter. 4. CathBot represents ?hand-held roBot for peripheral intravenous Catheterization?. The device uses a crank-slider mechanism and a solenoid actuator to convert the complicated intravenous catheterization motion to a simple linear forward motion. The user just needs to push the device?s handle forwards and the device completes the whole PIVC insertion procedure automatically. All the devices were characterized to ensure they can satisfy the design specifications. Then a series of comparative experiments were conducted to assess each of them. In the first experiment, 25 na�ve subjects were invited to perform 10 trials of PIVC on a realistic baby arm phantom. The subjects were divided into 5 groups, and each group was asked to do the PIVC with one device only (SVEI, SAID, SDOP, CathBot and regular iv catheter). The experimental results show that all devices can provide the needed assistance to significantly facilitate and improve the success rates compared to the conventional method. People who have no experience of PIVC operation before can achieve considerably high success rates in robot-assisted PIVC (86% with SVEI, 80% with SAID, 78% with SDOP and 84% with CathBot) compared to the control group (12%) who used a regular iv catheter.

One of the most important lessons from this work is that a model, even when far from reality, can be extremely useful for learning. This motivates a central philosophy of our approach: learning should build upon the robot's current knowledge rather than replace it. Our regularized memory-based learning puts this principle into practice by learning a local model from accumulated experience while retaining the global prior model to extrapolate where experience is sparse. This enables efficient and stable online learning from each new experience without resorting to uninformed exploration over a vast space of possible behaviors. Equally important to continual on-robot learning is safety, allowing the robot to repeatedly practice and improve in the real world. We construct a mutually reachable set that allows safe transitions between successive throws and catches, without driving either arm into a state from which its next action would require violating the robot's joint or actuator limits. Together, these ideas enable a bimanual robot with multi-fingered hands and onboard vision to safely learn and compose five canonical three-ball juggling patterns, including cascade, tennis, half-shower, shower, and box, within less than 5 minutes of real-world interaction. More broadly, this work points toward robots that build upon imperfect prior knowledge and continually refine their behavior through their own real-world experience.","url":"https://doi.org/10.48550/arxiv.2608.26800","authors":["Lee, Taeyoon","Wang, Chunpeng","Atkeson, Christopher G.","Rizzi, Alfred A.","Rojas, Nicolas"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.26800","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.2314/kxp:166628226x","name":"Smympartner - Symbiose von PAUL und Roboter Companion für eine emotionssensitive Unterstützung; Teilvorhaben: Konzeption und Realisierung von Schnittstellen, Oberflächen und Sensor-/Aktorsteuerung : Schlussbericht : Gesamtlaufzeit des Vorhabens: 01.04.2015-31.03.2018","source":"datacite","abstract":"Illustrationen","url":"https://doi.org/10.2314/kxp:166628226x","authors":["Szamlewska, Sebastian"],"tags":["Serviceroboter","Altenpflege","Mensch-Maschine-Kommunikation","Affective Computing","AAL-Technik","Krankenpflege","Educational Science","Medicine"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.2314/kxp:166628226x","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.26204/kluedo/13428","name":"Managing Expectation Gaps in Humanlike Robots: Toward Transparent and Acceptable Companions for University Students","source":"datacite","abstract":"Highly anthropomorphic social robots create a difficult interaction problem because their bodies suggest social, perceptual, and cognitive capability before the implemented system has shown what it can reliably support. This thesis examines that problem through Ameca, a full-body humanoid robot whose face, gaze, voice, speech, upper-body movement, and public recognisability make system behaviour socially interpretable. The work develops the 5A framework as an organising analytical lens for the anthropomorphic expectation gap. The framework diagnoses expectation mismatch through Anthropomorphism, Apparent Ability, and Anxiety, and addresses it through Alignment and Awareness. Across small-scale empirical studies and system evaluations with N = 929 reported participants, the thesis examines Ameca and the developed Empathic Mechanized Anthropomorphic Humanoid System (EMAH system) across embodiment, auditory dialogue, visual perception, behaviour generation, and tandem-language practice. The embodiment studies show how identity, voice, gender, gaze, affect, movement, and failure can be interpreted as cues from one social agent. The auditory-dialogue work connects speech recognition, Large Language Model (LLM)-based response generation, memory, retrieval, prompt boundaries, and lip-synchronised Text-to-Speech (TTS) to the stability of Ameca’s robot identity. The visual-perception work shows how eyes create expectations of seeing and fair attention, making Visual Question Answering (VQA), gaze control, active-speaker detection, and Hero selection socially consequential. The behaviour-generation work shows how facial expression, gaze shifts, mimicry, and pointing make ability visible, while timing, actuator limits, gesture detection, and morphology constrain what the robot can express or indicate. The tandem-language studies apply the framework in a bounded use case, where Ameca supports low-pressure German speaking practice through controlled dialogue, short turns, supportive correction, and clear role limits. The central contribution is an implementation-grounded account of expectation management for highly humanlike robots. The thesis shows that usability and acceptance depend on the fit between apparent ability, actual capability, interaction role, and failure behaviour. For researchers and designers, the findings indicate that appearance, sensing, dialogue, memory, movement, prompts, explanation, and repair need to be designed as one interaction system. Ameca can support meaningful Human-Robot Interaction (HRI) when interlocutors can recognise both the social invitation of the body and the technical boundary behind it.","url":"https://doi.org/10.26204/kluedo/13428","authors":["Ashok, Ashita"],"tags":["004 Informatik"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.26204/kluedo/13428","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.48550/arxiv.2601.00610","name":"Vision-based Goal-Reaching Control for Mobile Robots Using a Hierarchical Learning Framework","source":"datacite","abstract":"Reinforcement learning (RL) has strong potential in robotics, but exploration-based training complicates safe deployment on large-scale robots. For such applications, this paper proposes a novel hierarchical goal-reaching framework that integrates stereo visual pose estimation, constrained RL-based motion planning, actuator-level robust adaptive control (RAC), and supervisory safe-return logic. Stereo visual localization is used as the real-time pose-estimation interface with loop closing, map fusion, and relocalization. The RL planner generates smooth, feasible goal-reaching references using a problem-specific reward structure and motion constraints that promote goal progress, reduce oscillations, preserve vision-consistent smoothness, and respect the mechanical limits of a heavy skid-steered robot. At the actuation layer, a scaled conjugate-gradient (SCG)-trained deep neural network (DNN) approximates a quasi-static actuator feedforward map from wheel-speed data to nominal control input. This feedforward map is combined with a logarithmic-barrier-based RAC to compensate for residual modeling errors, slip-induced disturbances, and bounded mismatch between the nominal map and real actuator response. For the actuator-level wheel-tracking subsystem, uniformly ultimately bounded tracking with exponential convergence to a disturbance-dependent residual set is established under bounded uncertainty. A logarithmic safety supervisor monitors execution, detects unsafe operating conditions, including faults and localization inconsistencies, and switches the robot to safe-return mode. Experiments on a 6000 kg robot over asphalt and loose-soil terrain demonstrate approximately 3--4 cm final-position root mean square error (RMSE), accurate tracking of RL-generated commands, improved actuator-level performance over two RAC baselines, and successful autonomous recovery after fault injection.","url":"https://doi.org/10.48550/arxiv.2601.00610","authors":["Shahna, Mehdi Heydari","Mustalahti, Pauli","Mattila, Jouni"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2601.00610","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.48550/arxiv.2410.03086","name":"Design and Evaluation of a Compliant Quasi Direct Drive End-effector for Safe Robotic Ultrasound Imaging","source":"datacite","abstract":"Robot-assisted ultrasound scanning promises to advance autonomous and accessible medical imaging.

Single-point contact experiments from 2.5 N to 15 N show that the end-effector reduced force tracking RMS error by 80.1% on average. Trajectory scanning experiments at different speeds showed an average of 68.0% reduction in force tracking error.

We present CSymPlan, a certified symbolic planning and control framework for high-DOF manipulators with two complementary implementations: an offline implementation that precomputes certified reach-avoid feedback policies for known workspaces; and an online implementation that synthesizes or updates symbolic policies at runtime from changing task and perception information using parallelization. The offline implementation reduces the manipulator dynamics to a sampled perturbed double-integrator model in operational space through feedback linearization, treats torque-realization errors, modeling inaccuracies, and measurement uncertainty as bounded disturbances, and refines the synthesized symbolic policy to the Franka FR3 through a quantization--lookup--torque realization pipeline.

In this manuscript, we introduce two embedded proprioceptive sensors for insect-scale aerial robots: thin film piezoelectric polymers integrated directly into a driving actuator and a pitching hinge which track stroke and pitch angle, respectively. We fabricate the aforementioned size-agnostic mechanically intelligent structures (sensor-actuator, sensor-flexure) using laminate stack fabrication methods. Chirp experiments with our sensors integrated into an insect-size flapping-wing robot show accurate tracking of stroke (RMSE = 0.44 deg) and pitch (RMSE = 2.44 deg) angles in the relevant frequency range. As the first step towards demonstrating the utility of these sensors for enabling numerous onboard autonomy applications, including closed-loop wingbeat control and sensor fusion with existing insect-scale sensor suites for more accurate proprioception and localization, we show one application for each sensor. The proprioceptive hinge enables collision detection, reducing the chance of permanent damage if the robot's wing collides with an object. The proprioceptive actuator enables asynchronous flapping, which is hypothesized to increase adaptability and efficiency in insects and robots alike. A microrobot equipped with our proprioceptive actuator allows us to test these hypotheses with potential for improving flapping aerial robot performance.

Mobile microrobots have a great potential for a wide range of mid-term and long-term applications such as minimally invasive surgery, inspection, surveillance, monitoring and interaction with the microscale world. A systematic study of the state of the art of locomotion for mobile microrobots shows that there is a need for efficient locomotion solutions for mobile microrobots featuring several degrees of freedom (DOF). This thesis proposes and studies a new locomotion concept based on stepping motion considering a decoupling of the two essential functions of a locomotion principle: slip generation and slip variation. The proposed \"Modulated Friction Inertial Drive\" (MFID) principle is defined as a stepping locomotion principle in which slip is generated by the inertial effect of a symmetric, axial vibration, while the slip variation is obtained from an active modulation of the friction force. The decoupling of slip generation and slip variation also has lead to the introduction of the concept of a combination of on-board and off-board actuation. This concept allows for an optimal trade-off between robot simplicity and power consumption on the one hand and on-board motion control on the other hand. The stepping motion of a MFID actuator is studied in detail by means of simulation of a numeric model and experimental characterization of a linear MFID actuator. The experimental setup is driven by piezoelectric actuators that vibrate in axial direction in order to generate slip and in perpendicular direction in order to vary the contact force. After identification of the friction parameters a good match between simulation and experimental results is achieved. MFID motion velocity has shown to depend sinusoidally on the phase shift between axial and perpendicular vibration. Motion velocity also increases linearly with increasing vibration amplitudes and driving frequency. Two parameters characterizing the MFID stepping behavior have been introduced. The step efficiency ηstep expresses the efficiency with which the actuator is capable of transforming the axial vibration in net motion. The force ratio qF evaluates the ease with which slip is generated by comparing the maximum inertial force in axial direction to the minimum friction force. The suitability of the MFID principle for mobile microrobot locomotion has been demonstrated by the development and characterization of three locomotion modules with between 2 and 3 DOF. The microrobot prototypes are driven by piezoelectric and electrostatic comb drive actuators and feature a characteristic body length between 20 mm and 10 mm. Characterization results include fast locomotion velocities up to 3 mm/s for typical driving voltages of some tens of volts and driving frequencies ranging from some tens of Hz up to some kHz. Moreover, motion resolutions in the nanometer range and very low power consumption of some tens of µW have been demonstrated. The advantage of the concept of a combination of on-board and off-board actuation has been demonstrated by the on-board simplicity of two of the three prototypes. The prototypes have also demonstrated the major advantage of the MFID principle: resonance operation has shown to reduce the power consumption, reduce the driving voltage and allow for simple driving electronics. Finally, with the fabrication of 2 × 2 mm2 locomotion modules with 2 DOF, a first step towards the development of mm-sized mobile microrobots with on-board motion control is made.","url":"https://doi.org/10.5075/epfl-thesis-4108","authors":["Driesen, Walter"],"tags":["mobile microrobots","locomotion","resonance operation","low power consumption","piezoelectric actuators","electrostatic actuators","microrobots mobiles","opération en résonance"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2008","doi":"10.5075/epfl-thesis-4108","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.5281/zenodo.21767519","name":"CEET Robotics Artifact 01: The Grand Unified 3D Search Kernel, Khandey Constant, Hubble Tension Resolution \\& Total Mass TOE Matrix for a Non-Distractive Planetary Welfare Robot.","source":"datacite","abstract":"CEET Robotics Artifact 01: Complete 5-Part Mathematical, Structural, and Electro-Chronometric Blueprint for the Ultimate Non-Distractive Planetary Welfare Robot Core.

This study investigates whether learning-based control can exploit a high-dimensional tension space to improve disturbance robustness, fault tolerance, and low-peak-force contact control. We develop a four-joint, two-finger MuJoCo contact platform and compare three action representations: direct joint torque control (Joint), joint impedance control (Joint-Impedance), and redundant nonnegative tendon-force control (Tension). All policies are trained with proximal policy optimization (PPO), using five random seeds and 200,000 environment steps per seed. Model checkpoints are selected on held-out validation episodes rather than on the final test set. Without a contact-force penalty, Tension achieves higher average disturbance robustness and greater tolerance to a single disabled actuator channel. However, the fault-tolerance advantage decreases substantially when the fraction of disabled channels is matched, indicating that much of the apparent benefit originates from actuator-count redundancy. A second experiment introduces the same soft penalty for contact force above 6 N for all three control representations. Joint-Impedance restores high raw task success but frequently exceeds the peak-force target. When safe success is defined as task success with episode peak fingertip force no greater than 6 N, Tension provides the best average performance in the simplified simulation. The results provide preliminary evidence that redundant tension control can improve the trade-off between stable contact and low peak force. They do not establish universal superiority over joint-space control, because the comparison remains affected by action dimensionality, impedance parameterization, actuator count, and the use of a soft rather than hard force constraint.

The system augments conventional acoustic saxophones by supporting fingering actions while leaving breath control and musical expression to the human performer. We developed four robotic saxophones—soprano, alto, tenor, and baritone—which can be performed simultaneously to enable a robot-assisted saxophone quartet. Due to differences in instrument size, key layout, and performer posture across the four saxophone types, the placement and mechanism of actuators required careful design. Through iterative prototyping and experimentation, we identified suitable actuator configurations for each instrument. To support intuitive performance, we developed a dedicated music-game-style graphical user interface, enabling wireless communication and battery-powered operation.

The system augments conventional acoustic saxophones by supporting fingering actions while leaving breath control and musical expression to the human performer. We developed four robotic saxophones—soprano, alto, tenor, and baritone—which can be performed simultaneously to enable a robot-assisted saxophone quartet. Due to differences in instrument size, key layout, and performer posture across the four saxophone types, the placement and mechanism of actuators required careful design. Through iterative prototyping and experimentation, we identified suitable actuator configurations for each instrument. To support intuitive performance, we developed a dedicated music-game-style graphical user interface, enabling wireless communication and battery-powered operation. This design allows performers to handle the instruments in a manner comparable to conventional saxophone performance.

Magnetorheological fluid (MRF)-based actuators offer a compact and rapidly controllable solution for haptic feedback, but their practical implementation requires reliable fluid sealing, low-hysteresis excitation, accurate torque control, and stable long-duration operation. This article presents an integrated MRF haptic system featuring a compact magnetically self-sealed rotary actuator, low-hysteresis PWM operation, high-fidelity model-based torque rendering, and stable performance during long-time operation. Magnetostatic simulation guides the arrangement of magnetic and nonmagnetic materials to focus flux in the multidisk torque and permanent-magnet sealing regions, enabling a maximum 600 N$\\cdot$mm/A output. Experiments show that higher PWM frequencies reduce hysteresis and improve repeatability. At 10 kHz, the response is represented by a nonlinear model that varies with the direction and speed of torque change. The real-time controller combines feedforward, hysteresis compensation, PI feedback, and sliding-mode correction.

Our analysis is based on real robot experimentation and models at different levels of abstraction. Distributed boundary coverage is an instance of the distributed coverage problem and has applications such as inspection of structures, de-mining, cleaning, and painting. Coverage is a particularly good example for the benefits of a multi-robot approach due to the potential for parallel task execution and additional robustness out of redundancy. The constraints imposed by a potential application, the autonomous inspection of a jet turbine engine, were our motivation for the algorithms considered in this thesis. Thus, there is particular emphasis on how algorithms perform under the influence of sensor and actuator noise, limited computational and communication capabilities, as well as on the policies about how to cope with such problems. The algorithms developed in this dissertation can be classified into reactive and deliberative algorithms, as well as non-collaborative and collaborative algorithms. The performance of these algorithms ranges from very low to very high, corresponding to highly redundant coverage to near-optimal partitioning of the environments, respectively. At the same time, requirements and assumptions on the robotic platform and the environment (from no communication to global communication, and from no localization to global localization) are incrementally raised. All the algorithms are robust to sensor and actuator noise and gracefully decay to the performance of a randomized algorithm as a function of an increased noise level and/or additional hardware constraints. Although the deliberative algorithms are fully deterministic, the actual performance is probabilistic due to inevitable sensor and actuator noise. For this reason, probabilistic models are used for predicting time to complete coverage and take into account sensor and actuator noise calibrated by using real hardware. For reactive systems with limited memory, the performance is captured using a compact representation based on rate equations that track the expected number of robots in a certain state. As the number of states explode for the deliberative algorithms that require a substantial use of memory, this approach becomes less tractable with the amount of deliberation performed, and we use Discrete Event System (DES) simulation in these cases. Our contribution to the domain of multi-robot systems is three-fold. First, we provide a methodology for system identification and optimal control of a robot swarm using probabilistic models. Second, we develop a series of algorithms for distributed coverage by a team of miniature robots that gracefully decay from a near-optimal performance to the performance of a randomized approach under the influence of sensor and actuator noise. Third, we design an implement a miniature inspection platform based on the miniature robot Alice with ZigBee ready communication capabilities and color vision on a foot-print smaller than 2 × 2 × 3 cm3.","url":"https://doi.org/10.5075/epfl-thesis-3919","authors":["Correll, Nicolaus"],"tags":["Swarm Robotics","Distributed Coverage","Multi-Robot Systems","essaim de robots","couverture distribuée","systèmes multi-robots"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2007","doi":"10.5075/epfl-thesis-3919","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.18720/spbpu/2/id26-363","name":"Модульная сварочная головка для индукционной сварки термопластичных композиционных материалов роботами-манипуляторами","source":"datacite","abstract":"Статья посвящена проектированию исполнительного мехатронного органа для индукционной сварки углепластиков.

However, this is non-intuitive and makes achieving desired job properties a challenging task requiring operators to complete extensive and costly training. Despite this, operator fatigue is common with implications for personal safety, project timeliness, cost, and quality. While full automation is not yet achievable due to unpredictability and the dynamic nature of the environment and task, shared control paradigms allow operators to issue high-level commands in an intuitive, task-informed control space while having the robot optimize for achieving desired job properties. In this paper, we compare a number of modes of teleoperation, exploring both the number of dimensions of the control input as well as the most intuitive control spaces. Our experimental evaluations of the performance metrics were based on quantifying the difficulty of tasks based on the well known Fitts' law as well as a measure of how well constraints affecting the task performance were met. Our experiments show that higher performance is achieved when humans submit commands in low-dimensional task spaces as opposed to joint space manipulations.","url":"https://doi.org/10.48550/arxiv.1905.04428","authors":["Mower, Christopher E.","Merkt, Wolfgang","Davies, Aled","Vijayakumar, Sethu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.48550/arxiv.1905.04428","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.48550/arxiv.2608.14865","name":"Real-time Estimator of Actuator Control and Health (REACH) on an Eel-Inspired Soft Robot","source":"datacite","abstract":"An actuator health estimation algorithm for a soft swimming robot that can perform anguilliform swimming is developed.

Termed REACH (Real-time Estimator of Actuator Control and Health), the architecture employs a soft robot model, sigma point filter, and a formal statistical hypothesis test to adequately capture the nonlinearities and changes over time. The performance of REACH using three sensor types (GPS, IMU, and Bend Sensor) with one sensor on each actuator is compared, demonstrating that both bend sensor and IMU are adequate choices. Sensor quantity and placement are evaluated for IMU and bend sensor, showing two sensors are sufficient for IMU, whereas three sensors are needed for bend sensor. Three swimming gaits (linear swimming, wide turning, tight turning) are compared, demonstrating that REACH can successfully predict actuator health for all three gaits, with minimal differences in performance. A filter validation method shows the fault estimation algorithm is statistically consistent in finding the correct degradation. The approach is experimentally evaluated using bend sensor data collected from a fish robot, demonstrating that REACH can successfully estimate actuator health with noisy data and variations in manufacturing.","url":"https://doi.org/10.48550/arxiv.2608.14865","authors":["Jiang, Zhangjingyi","Park, Myungsun","Tolley, Michael T.","Campbell, Mark"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.14865","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.5281/zenodo.20010790","name":"SΔϕ-52 — Body as Non-Deferrable Cost Return: Operational Body, Body Theater, and Distributed AI Body Infrastructure (v1.0, AI-Readable Package)","source":"datacite","abstract":"SΔϕ-52 defines bodyhood as non-deferrable cost return within the Sofience–Δϕ Formalism Series.

The report proposes a three-phase transition model in which the human labour ecosystem created during early robotics expansion is itself progressively compressed through autonomous diagnostics, standardised deployment, robot-to-robot servicing, autonomous logistics integration, and cloud-based orchestration systems. Key themes explored in Volume II include: • labour compression within the robotics sector itself• SME continuity under demographic labour scarcity• adaptive operational inference within small business environments• autonomous deployment frameworks (“the robot arrives on a bus”)• lease moonlighting and multi-tenant robotic utilisation• orchestration-layer concentration risk• infrastructure and energy dependence• regulatory latency• and the emergence of robotics as ambient economic infrastructure The analysis argues that in many ageing economies, robotics deployment may increasingly function not primarily as labour elimination, but as labour-substitution infrastructure required to sustain sectors facing structural workforce scarcity. Across both volumes, the report remains grounded in publicly observable platform capabilities, industrial automation trends, infrastructure economics, and deployment trajectories visible as of mid-2026, including developments associated with Tesla Optimus, Figure AI, Agility Robotics, Boston Dynamics, Sanctuary AI, Unitree, and broader Chinese robotics ecosystems.

Systematic scanning is difficult due to time-consuming per-sample testing and the high-dimensional parameter space affecting performance. To address this, we propose an optimization pipeline enabled by a novel testing robot capable of scanning DEA lifetime. The robot integrates electro-mechanical property measurement, programmable voltage input, and multi-channel testing capacity. Using it, we scanned the lifetime of Elastosil-based linear actuators across parameters including input voltage magnitude, frequency, electrode material concentration, and electrical connection filler. The optimal parameter combinations improved operational lifetime under boundary operating conditions by up to 100% and were subsequently scaled up to achieve higher force and displacement output.

However, DRL methods often require extensive training time, and the resulting policies do not generalize well to different robot configurations or varying numbers of actuators. In this article, we introduce a novel DRL approach for controlling CDPRs that does not depend on the specific robot configuration. Our method trains an actuator-level policy that controls each motor to achieve its target cable length, in contrast to conventional DRL approaches that learn to control the entire robot to reach a desired end-effector position. To the best of our knowledge, this is the first work to apply DRL to control CDPRs using an actuator-level policy. This approach offers two main advantages: (i) a single shared policy can be applied to any CDPR configuration, regardless of actuator count, and (ii) reliance on inverse kinematics, avoiding the more challenging forward kinematics problem. Training is performed in simulation, and the learned policy is successfully transferred to a real CDPR. Experimental results show that the actuator-level policy (ALP) surpasses traditional reinforcement learning methods in both robustness and precision. We further control a real 8-motor CDPR with 3D motion using a policy trained on a simulated 4-motor planar CDPR operating in 2D. This illustrates that the proposed method is applicable to any CDPR configuration, independent of actuator number or placement.","url":"https://doi.org/10.48550/arxiv.2608.07546","authors":["Bouaouda, Abir","Boutayeb, Mohamed","Charpillet, François","Martinez, Dominique","Pannequin, Rémi"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.07546","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.5075/epfl-thesis-3348","name":"Modélisation et commande du moteur piézoélectrique à onde progressive","source":"datacite","abstract":"Piezoelectric motors are resonant vibromotors. They represent a new actuator generation in the field of servo-drives. In particular, the travelling wave ultrasonic motor presents a high torque at low speed, a zero speed torque without feeding, low sensitivity to electromagnetic disturbances as well as being a more compact solution if compared to conventional electromagnetic motors. Much researches has been performed by others to determine an analytical model based on the identification of an electromagnetic equivalent circuit or on exploitation of a theoretical model based on numerical approaches, which use finite elements methods. While leading to satisfactory analysis, these modeling methods can hardly be exploited in the design of control algorithms. Indeed, they require considerable processing resources to generate and visualize the results. For this reason, we introduce in this thesis, an analytical model that is easily adaptable to operational applications and control techniques. The proposed analytical model has been validated by comparing measured characteristics with those obtained in simulations, which was possible thanks to the realization of a modular test bench. The travelling wave ultrasonic motor is characterized by strong non-linearity. It also depends highly on the wear state of the materials, which is difficult to model, and on the contact surface between stator and rotor. In addition, the mechanical resonance frequency experiences drift due to the variations of temperature. These considerations of strong non-linearities and parameter sensitivities of the motor represent a challenge for the study and design of an efficient and robust control strategy. We introduce with this thesis a new control approach that guarantees a closed loop response which is independent of the motor operating point. Moreover, the proposed control method allows to avoid the discontinuities typically present with this type of actuator with a very reasonnable hardware requierments. Finally, an important extension in the product range of the piezoelectric actuators is proposed in the last part of this thesis. It acts to develop an fMRI (functional Magnetic Resonance Imaging) compatible haptic interface with one degree of freedom. The use of a robotic interface in conjunction with an fMRI environment would enable neuroscientists to investigate the brain mechanism used to perform tasks with arbitrary dynamics, and could become a critical tool in neuroscience and rehabilitaiton. There is, however, a major problem for robot working within an fMRI environment : conventional actuators and materials interfere with the strong permanent magnetic field and the fast switching magnetic field gradients. Consequently, non-ferromagnetic materials must be used to avoid forces on the device itself, that can compromise its performance and may result in hazardous conditions for the patient or the medical staff. In addition, the materials should be non-conducting to avoid the generation of eddy currents. The travelling wave ultrasonic motor was used because it provides benefits compared to the conventional electromagnetic actuators. Non-ferromagnetic piezoelectric ceramic material is used and as a result motor operation is not affected by the presence of the strong magnetic fields ecountered in the clinical scanners.","url":"https://doi.org/10.5075/epfl-thesis-3348","authors":["Bullo, Matteo"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2005","doi":"10.5075/epfl-thesis-3348","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"doi:10.5075/epfl-thesis-3194","name":"Bio-inspired vision-based flying robots","source":"datacite","abstract":"There are not yet autonomous flying robots capable of manoeuvring in small cluttered environments as insects do. Encouraged by this observation, this thesis presents the development of ultra-light flying robots and control systems going one step toward fully autonomous indoor aerial navigation. The substantial weight and energy constraints imposed by this indoor flying robots preclude the use of powerful processors and active distance sensors. Moreover, flying systems require fast sensory-motor mapping despite their limited processing power. In order to cope with those apparently contradictory constraints, our approach takes inspiration from flying insects, which display efficient flight control capability in complex environments in spite of their limited weight and relatively tiny brain. In particular, they are able to stabilise their course, avoid obstacles and control their altitude, which represents the basic mechanisms we want to have on an indoor flying robot. To achieve efficient flight control, insects rely essentially on two sensory modalities: vision and gyroscope. They possess two low-resolution, compound eyes which are particularly sensitive to image motion (optic flow). In their visual system, some neurons are known to be responsible for detecting self-motion and impending collisions based on optic-flow. Gyroscopic information coming from two mechanosensors located behind the wings complements visual cues in tasks such as gaze and course stabilisation. In this thesis, we explore the application of such biological principles to develop navigation controllers for indoor flying robots. In particular, we address the problem of how low-resolution vision and gyroscopic information can be mapped into actuator commands in real-time to maintain altitude, stabilise the course and avoid obstacles. As an alternative to hand-crafting control systems based on biological principles, in a second phase, we take inspiration from the evolutionary process that eventually generated those animals and apply artificial evolution to search for alternative control systems and behaviours that can fit the constraints of indoor flying robots. Instead of replicating the biomechanics of insect flight, our targeted robotic platform is a fixed-wing airplane capable of flying indoors at very low speed (&lt;1.5m/s). This testbed weights only 30-grams and is equipped with several miniature cameras and a small gyroscope. In order to progress gradually in the task of automating indoor flying robots, two other platforms have been developed, namely a miniature wheeled robot and a small indoor airship. All three robotic platforms feature very similar sensors and electronics in order to facilitate the transfer of software modules and control strategies. Applying the proposed bio-inspired approach, we succeeded in automating the steering (course stabilisation and obstacle avoidance) of the 30-gram airplane in a square textured arena. Then, using artificial evolution with the airship, we obtained alternative navigation strategies based on the same sensory modalities.","url":"https://doi.org/10.5075/epfl-thesis-3194","authors":["Zufferey, Jean-Christophe"],"tags":["aerial robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2005","doi":"10.5075/epfl-thesis-3194","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.48550/arxiv.2608.07328","name":"Learning Fault-Tolerant Locomotion with Adaptive Gait Timing","source":"datacite","abstract":"Hardware failures require legged robots to rapidly reorganize coordination and gait timing to maintain stability and mobility.

We demonstrate that an ANN trained entirely in simulation can be transformed into an SDNN compatible with Intel’s Loihi 2 neuromorphic architecture, enabling low-latency and energy-efficient inference. The SDNN is deployed on Loihi 2, then evaluated in NVIDIA’s Omniverse Isaac Lab simulation environment for closed-loop control of Astrobee’s motion. We compare execution performance between GPU and Loihi 2. The results highlight the feasibility of neuromorphic platforms for robotic control and establish a pathway toward energy-efficient, real-time neuromorphic computation for future space and terrestrial robotics applications. _x000D_ Power constraints are a critical consideration for many robotic applications, particularly in space and mobile environments.

Results demonstrate an SDNN running on Loihi 2 for controlling the Astrobee is 20x more energy efficient with 2x throughput compared to running on a GPU with only a small cost to accuracy. _x000D_ Beyond small free-flying platforms such as Astrobee, many real-world missions require robust, low-power control systems capable of sustained operation under strict energy budgets. Space exploration is particularly constrained with respect to onboard computing resources due to environmental challenges, including radiation exposure, as well as size, weight, power, and cost (SWaP-C) limitations. Consequently, current radiation-hardened processors, while reliable for long-duration missions, provide limited computational performance compared to modern terrestrial hardware. _x000D_ Several past space robotic platforms encountered limitations due to actuator degradation, restricted onboard computation, and power exhaustion, conditions under which neuromorphic RL-based control could provide tangible benefits. For example, NASA’s Kepler mission experienced reaction wheel degradation that reduced pointing accuracy and ultimately ended its primary mission. More adaptive torque-management policies learned through reinforcement learning and executed at low power on neuromorphic hardware could have mitigated reaction-wheel loading and prolonged operational life. Continuous, low-power neuromorphic inference may also enable more resilient attitude and propulsion control during sensor anomalies without exceeding spacecraft power constraints. _x000D_ These considerations motivate the development of control pipelines that integrate data-driven learning with low-power neuromorphic execution.

However, their adoption in both research and practical applications has been hindered by reproducibility issues arising from complex fabrication and assembly processes, challenging kinematic modeling, and a lack of intuitive control interfaces. To address these challenges, we present a novel open-source continuum robot design. The platform features a simplified fabrication pipeline enabled by multi-material 3D printing, allowing the arm to be fabricated as a monolithic compliant structure with minimal assembly. Control is achieved through an isomorphic teleoperation interface that establishes a direct actuator-level mapping, eliminating the need for explicit kinematic modeling and providing a singularity-free mapping. Building on this hardware design, the platform further supports imitation-learning-based autonomous control. The proposed system is evaluated through hardware characterization and a set of manipulation tasks. Experimental results demonstrate that the platform provides a reproducible, learning-ready continuum robot system, accelerating algorithmic development and systematic benchmarking for the continuum robotics community.","url":"https://doi.org/10.48550/arxiv.2606.20389","authors":["Tang, Ziyuan","Xiao, Chenxi"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.20389","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.48550/arxiv.2606.14606","name":"Interaction Dynamics for Dexterous Manipulation","source":"datacite","abstract":"Dexterous manipulation is fundamentally a problem of interaction dynamics: the hand must track precise finger trajectories, regulate the contact force exchanged with grasped objects, respect actuation and safety limits, and remain predictable when contact persists -- objectives in tension for any fixed-gain controller.

Conventional approaches based on autoencoders or variational autoencoders learn average behaviors by projecting sensor and actuator signals into a low-dimensional latent space; however, exploration within the latent space alone has limited capability to handle out-of-distribution or abnormal states that are not included in the training data. To address this limitation, this study proposes a diffusion-based framework for body schema learning in musculoskeletal robots. Unlike generative models that operate through low-dimensional latent spaces, diffusion models can directly and iteratively estimate physically consistent sensor and actuator values in the high-dimensional space through a denoising process, even under partial observations and constraints, without requiring retraining. By formulating body schema adaptation as a gradient-guided denoising process, the proposed method enables adaptive estimation of appropriate muscle lengths and muscle tensions even under abnormal conditions such as muscle rupture and actuator jamming.

The optimization is performed for a walking task using gait data from a stroke subject, and the result is a set of actuator Arrangements with optimal parameters for the analyzed task and selected user.

The system is modeled as a directed graph of physical, functional, and model based modules, with edges capturing information and control dependencies. Adaptation is posed as a joint optimization over architectural configurations and module parameters, subject to operational constraints using a Monitor-Analyze-Plan-Execute loop-based finite state machine.

The approach is demonstrated on a differential drive robot under sensor drift and actuator faults. A fixed architecture accumulates tracking errors of up to 24 m and 13 m, respectively, whereas architecture aware adaptation reduces error under 1.5 m in each case, by selecting fault appropriate configurations.

By contrast, the SLIP model itself has never been implemented in a robot and validated experimentally. This thesis addresses the development and validation of a robotic SLIP, a planar one-legged hopping robot with only one actuator. A feasibility study was performed using numerical simulation. The experimental platform was designed and built based on SLIP-model features. A hopping controller that conceptually reproduced the self-stability property of the SLIP model was implemented. Running was achieved at 6.7 leg lengths per second, which is, to date, the fastest dimension-less speed for a single-legged robot. Simulation and experimental data demonstrated periodic and robust stability. The SLIP model was qualitatively validated for a particular gait in simulation and experimentation.","url":"https://doi.org/10.82308/8935","authors":["Sato, Akihiro"],"tags":["Mechanical Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2005","doi":"10.82308/8935","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.48550/arxiv.2506.04680","name":"A Three-Stage Offline SDRE-Based Control Framework for Human Motion Reproduction on a Suspended Bipedal Robot","source":"datacite","abstract":"Evaluating lower limb exoskeletons directly with human subjects can expose users to risk when actuator faults, joint misalignment, or unsuitable assistance occur. Therefore, captured human motion must first be converted into commands that are executable by the robot hardware and repeatable across trials. This paper presents a three-stage offline command generation framework for reproducing lower limb motion and torque on a suspended bipedal robot platform used as a robotic bench system for exoskeleton evaluation. First, State-Dependent Riccati Equation control is applied to the robot dynamic model to obtain a reference torque trajectory associated with measured lower limb motion. Second, parameterized optimization converts this reference into trapezoidal joint velocity commands subject to motor speed and acceleration limits. Third, a proportional-integral-derivative linear quadratic regulator (PID-LQR) compensation refines the command profiles using experimental tracking data. Walking and squatting motions recorded by a Vicon motion capture system are reproduced on the suspended robot to evaluate tracking accuracy and repeatability. The results show that the average root mean square error (RMSE) and standard deviation (STD) of joint angles across repeated trials remain below 3° and 0.15°, respectively. Comparisons of joint angles and torques further show that the proposed method achieves lower maximum RMSE and STD values than the two baseline controllers in all reported cases. These results indicate that the proposed three-stage control provides repeatable and actuator-feasible motion reproduction on a suspended bipedal robot platform as a preliminary test environment for lower limb exoskeleton research before tests involving human subjects.","url":"https://doi.org/10.48550/arxiv.2506.04680","authors":["Huang, Ping-Kong","Lan, Chien-Wu","Wu, Chin-Tien","Lin, Ching-Kai"],"tags":["Robotics (cs.RO)","Optimization and Control (math.OC)","FOS: Computer and information sciences","FOS: Mathematics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2506.04680","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.82308/19015","name":"Kinematics and optimization of a parallel robotic wrist mechanism with redundancey","source":"datacite","abstract":"This thesis presents a new robot wrist design that is fully parallel and actuator redundant. Actuator redundancy refers to the addition of more actuators than are strictly necessary to control the mechanisms without increasing the mobility. The uses of this form of redundancy include the ability to partially control the internal forces, increase the workspace, remove singularities and augment the dexterity. As the proposed wrist design is fully parallel, it exhibits high structural rigidity accompanied by a large load carrying capacity as well as superior dynamic response. In the first part of this thesis, the wrist architecture is developed and then analyzed with respect to its kinematics and the resulting singular surfaces. The workspace is then investigated taking into account these factors as well as limits imposed by the collision of movable links and fixed trusses of the assembly. Next, the kinematics of tendon actuated mechanisms are investigated. Tendons display an intrinsically non-linear behaviour. They are shown to have additional constraints that result in singularities of a type not found in linear systems. These act to reduce the workspace and influence the mapping of external to internal forces.

Par exemple, un robot amphibie à pattes qui aurait apprit à distinguer le sable et la mer pourra choisir de lui-même la démarche appropriée : marcher sur le sable, et nager dans l'eau. Cette même information sur le type de terrain peut aussi être utile pour guider un robot, lui permettant d'éviter des types de terrains spécifiques. Nous abordons la problématique d'identification des terrains autour de deux axes principaux: un problème de capture d'information (sensoriel), et un problème d'apprentissage. Dans le problème de la capture d'information, la question traitée est celle d'extraire l'information pertinente à l'identification du type de sol à partir de capteurs sur un robot, ou à l'aide d'une sonde tactile.

What distinguishes SPOTT from other behavioral architectures is that it is able to guarantee task completion for navigational tasks under many different scenarios. SPOTT provides a bridge for linking behavioral (i.e., reactive) and symbolic control and has actually been interfaced with the logical reasoning system called COCOLOG. One of the roles of the symbolic reasoner is to help guarantee task completion in the situations where SPOTT is not able to solely do so. In essence, SPOTT is a real-time AI system which is responsible for dynamically adapting to changing environmental circumstances in order to successfully execute and complete a set of navigational tasks for an autonomous mobile robot. SPOTT consists of a behavioral controller, a local dynamic path planner, and a global path planner, as well as a map database and a graphical user interface. The behavioral control formalism is called TR+ and is based on an adaptation and extension of the Teleo-Reactive (TR) formalism. TR+ rules make decisions which affect actuator control and map database maintenance. A dynamic local path planner continually polls the map database in order to navigate around newly encountered obstacles. The local dynamic path planner is based on a potential field method using harmonic functions, which are guaranteed to have no spurious local minima. The global planning module advises the local planning module in order to position and project the global goal onto the local border. A real-time and parallel implementation of SPOTT using a message passing software package called PVM has been developed and tested across a collection of ten to fifteen heterogeneous workstations.

They are being used in many industries from entertainment to space exploration. McGill University's Ambulatory Robotics Laboratory recently introduced a new class of quadruped robot---the SCOUT series. These robots feature only one actuated degree of freedom per leg. By keeping the degrees of freedom to a minimum, this class of robots is simpler, less expensive and more reliable than most legged robots built to date. The design and development of the second of these robots, SCOUT II, is the topic of this thesis. Unlike its predecessor SCOUT I, SCOUT II has unactuated prismatic knee joints in addition to the revolute joints, which allow compliant walking, stair-climbing and running gaits to be explored. SCOUT II is a self-contained, autonomous mobile robot whose primary purpose is to serve as the testbed for the various gaits that are being developed. This thesis describes the robot's mechanical design, electrical design, sensors and construction. A preliminary stair-climbing algorithm is developed and simulated. An attempt, though partially unsuccessful, is made to implement this algorithm on SCOUT II. The reasons for the discrepancies between the simulations and the actual system are outlined. This will provide useful insight on modelling parameters, actuator limits and robot dynamics for future stair-climbing, walking and running algorithms that are developed for SCOUT II.","url":"https://doi.org/10.82308/34439","authors":["Battaglia, Robert F."],"tags":["Mechanical Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"1999","doi":"10.82308/34439","addedAt":"2026-08-31T06:34:12.096Z","updatedAt":"2026-08-31T06:34:12.096Z"},{"id":"doi:10.82308/25226","name":"Dynamically estimating mobile range camera pose from invariant feature measurements","source":"datacite","abstract":"Complex robotic tasks such as autonomous exploration and grasping demand the co-operation of sensors and actuators.

We examine the problem of determining the pose of a robot-mounted range-finding camera, and present a class of solutions motivated by the idea that mobile camera calibration is best addressed by an ongoing dynamic estimation process. We use range measurements and known robot kinematics to provide the estimate of camera pose which is maximally consistent with the available data.

Soft Wearable Robot with an Adjustable Twisted String Actuator and a Two‐Stage Transmission Mechanism for Manual Handling Tasks","source":"crossref","abstract":"A manual handling task is one of the most common causes of back injuries, accounting for nearly 31.9% of the total work‐related injuries. To promote a safe working environment for workers, wearable robots (wearables) are rapidly emerging to fulfill various needs in human‐robot interactive tasks. Although numerous studies have successfully developed wearables to assist humans, they are often limited to supporting a single degree of freedom (DoF) of the human body with a single actuator. However, as humans tend to use multiple parts of their bodies, additional actuators and mechanisms to transmit force/motion are necessary to realize multi‐DoF, which increases the volume, price, and complexity of the wearables. To address these issues, a multi‐DoF wearable robot (WeaRo) with an adjustable twisted string actuator (ATSA) and a two‐stage transmission mechanism (2TM) is proposed. By introducing the novel ATSA and 2TM, the proposed WeaRo achieves multi‐DoF (lumbar and arm) with only a single electric motor and ATSA. Experimental results demonstrate that the proposed WeaRo effectively reduces the maximal voluntary contraction (%MVC) of lumbar, biceps, and triceps muscles by a maximum of 18.2, 29.1, and 27.0%, respectively without constraining users’ movements. Additionally, the fabric‐based design ensures a lightweight solution weighing 5.2 kg including batteries.","url":"https://doi.org/10.1002/aisy.202400700","authors":["Dongun Lee","Sinyoung Lee","Donghyun Lee","Dongjun Shin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-01-08T04:09:53Z","doi":"10.1002/aisy.202400700","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1109/hri61500.2025.10973821","name":"Design of a Lightweight Modular Cable-Driven Actuator for Enhanced Versatility in Soft Wearable Robotics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/hri61500.2025.10973821","authors":["Gyowook Shin","Junghoon Park","Dong Hyun Kim","Sang-Hun Kim","Chiyul Yoon","Yongtae Giovanni Kim","Jung-Sik Hwang","Seungyong Hyung","Minhyung Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-12T17:38:30Z","doi":"10.1109/hri61500.2025.10973821","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1016/j.sna.2025.116712","name":"The bi-directional motion behavior of the vibration-driven locomotion robot excited by a dielectric elastomer actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.sna.2025.116712","authors":["Lili Meng","Xiaojian Wang","Shaochong Zhang","Fucai Li","Hongguang Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-19T23:44:15Z","doi":"10.1016/j.sna.2025.116712","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.20965/jrm.2025.p0043","name":"Fan-Shaped Pneumatic Soft Actuator that Can Operate Bending Motion for Ankle-Joint Rehabilitation Device","source":"crossref","abstract":"Nowadays, owing to declining birthrates and an aging population, patients and the elderly requiring rehabilitation are not getting enough physical activity. In addressing this issue, devices for rehabilitating them have been researched and developed. However, rehabilitation devices are almost exclusively used for patients who can get up, rather than those who are bedridden. In this study, we aim to develop a rehabilitation device that can provide passive exercise for bedridden patients. The ankle joint was selected as the target joint because the patients who have undergone surgery for cerebrovascular disease remain bedridden, and early recovery in the acute stage is highly desirable. We proposed and tested a fan-shaped pneumatic soft actuator (FPSA) that can expand and bend stably at angles when supply pressure is applied as an actuator for a rehabilitation device to encourage patient exercise. However, the previous FPSA’s movement deviates from the arch of the foot owing to increased supply pressure. In the ideal case, FPSA should push the arch of the foot in an arc motion. This study proposes and tests the FPSA that can operate a bending motion to provide passive exercise to the ankle joint using tensile springs and a winding mechanism powered by a servo motor. The proposed FPSA has a significant advantage of exhibiting no hysteresis in its pressure-displacement characteristics. The configuration and static analytical model of the improved FPSA are described.","url":"https://doi.org/10.20965/jrm.2025.p0043","authors":["So Shimooka","Hirosato Yokoya","Masanori Hamada","Shun Shiomi","Takenori Uehara","Takahiro Hirayama","Tetsushi Kamegawa"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-19T15:02:07Z","doi":"10.20965/jrm.2025.p0043","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1002/asjc.3594","name":"Learning estimator‐based fault‐tolerant control for robot manipulators with partial loss of actuator effectiveness","source":"crossref","abstract":"Abstract This paper proposes a fault‐tolerant control approach for robot manipulators, addressing challenges such as parameter uncertainties, external disturbances, control input limitations, and partial loss of actuator effectiveness.

To address the challenge of control input saturation, a saturation compensation mechanism is integrated into the control law.

Design/methodology/approach By synergistically configuring permanent magnets and excitation coils in a hybrid magnetic circuit structure, the permanent magnets enable power-off self-locking while cooperating with the excitation coils to establish a dual-mode actuation system. A mathematical model was developed based on the magnetic circuit theory, and finite element simulations were used to validate the magnetic decoupling characteristics between the transmission and braking modules. The control performance was further evaluated through prototype experiments. Findings Experimental results demonstrate that in the transmission mode, the output torque exhibits a linear relationship with the excitation current, reaching 30 N·m at 3 A. In the braking mode, a reverse excitation of 1.3 A enables dynamic torque regulation from 15 N·m (zero-current self-locking) to 3.2 N·m. Originality/value This study innovatively introduces a magnetically decoupled dual-mode drive architecture for magnetorheological flexible actuators, integrating power-off self-locking and dynamic braking functionalities. This breakthrough overcomes the coupling limitations between stiffness adjustment and braking performance in conventional actuators, offering high integration density and strong functional expandability.","url":"https://doi.org/10.1108/ir-03-2025-0115","authors":["Xiankang Huang","Zuzhi Tian","Shuyou Wang","Haopeng Li","Jinjie Ji","Fangwei Xie"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-23T03:17:56Z","doi":"10.1108/ir-03-2025-0115","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1115/1.4065462","name":"An Origami-Enabled Soft Linear Actuator and Its Application on a Crawling Robot","source":"crossref","abstract":"Abstract Soft linear actuators have strong deformation ability and good environmental adaptability, which have been widely used in soft robot design. However, little work has focused on designing soft linear actuators with balanced performances, featuring fast driving speed, large output displacement, being lightweight, and miniaturization. Herein, we present a novel soft linear actuator design based on the Kresling origami structure. By driving the Kresling tubes with a servo motor, the soft linear actuator has good compliance and strong environmental adaptability and can achieve a driving speed, large driving force, and high control precision comparable to the traditional electrical motor. The analytical models of the Kresling tubes and the whole actuator are respectively derived to analyze the mechanical properties, determine the optimal geometry of the Kresling tube, and evaluate the driving performance of the whole actuator. The actuator prototype is fabricated by 3D printing, and the actual driving performance is tested. It is shown that the prototype can achieve a maximum output displacement of 18.9 mm without payload or 16 mm under a payload of 30 N. Finally, as a case study, the soft linear actuator is applied to a crawling robot, where the maximum moving speed of 28 mm/s is reached.","url":"https://doi.org/10.1115/1.4065462","authors":["Shuiqing Yan","Keyao Song","Xiashuang Wang","Jiake Li","Zhe Ma","Xiang Zhou"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-05-03T15:27:00Z","doi":"10.1115/1.4065462","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.5739/jfpsij.18.8","name":"Slim Pipe Inspection Robot Using Extension type Flexible Pneumatic Actuator with Axial Elastic/Rigid Fiber Restraint","source":"crossref","abstract":"","url":"https://doi.org/10.5739/jfpsij.18.8","authors":["Takumi ISHIBASHI","Takashi SHINOHARA","Tetsuya AKAGI","Shujiro DOHTA","Feifei CHO","Masashi YOKOTA","Yuma ADACHI"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-25T22:09:41Z","doi":"10.5739/jfpsij.18.8","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1016/j.cja.2025.103494","name":"A high liftoff speed insect-scale aerial robot direct-driven with piezoelectric bimorph PZT actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.cja.2025.103494","authors":["Xiang LU","Yulie WU","Jie CHEN","Yang CHEN","Canhui YIN","Xuezhong WU","Dingbang XIAO"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-03-19T18:29:42Z","doi":"10.1016/j.cja.2025.103494","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1109/lra.2025.3623024","name":"Learning Quadrupedal Locomotion for a Heavy Hydraulic Robot Using an Actuator Model","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2025.3623024","authors":["Minho Lee","Hyeonseok Kim","Jin Tak Kim","Sangshin Park","Jeong Hyun Lee","Jungsan Cho","Jemin Hwangbo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-17T17:42:36Z","doi":"10.1109/lra.2025.3623024","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1109/lra.2025.3585391","name":"Actuator Dynamics-Aware Model Predictive Control of a Wheeled Inverted Pendulum with a Fan","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2025.3585391","authors":["Dohyeon Kim","Yeongtae Jung"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-07T17:53:29Z","doi":"10.1109/lra.2025.3585391","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.3390/act14060299","name":"Metal Thickness Measurement Using an Ultrasonic Probe with a Linear Actuator for a Magnet-Type Climbing Robot: Design and Development","source":"crossref","abstract":"The inspection of oil storage tanks is a critical measure to prevent the risk of oil leakage. Therefore, research has focused on magnet-type climbing robots for automated tank inspections. While existing magnet-type climbing robots have demonstrated significant improvements in climbing steel structures, their capability in terms of metal thickness measurement has not been previously evaluated. During thickness inspections, ultrasonic thickness sensors require a probe to be pressed against target surfaces. To automate metal thickness measurements, this pressing motion of the probe needs to be performed by the robot. This study introduces a novel metal thickness measurement device comprising an ultrasonic probe, a linear actuator, a gel pump, and a pressure sensor designed for a magnet-type climbing robot. The linear actuator moves the probe to its initial position, the gel pump injects a coupling gel, and then the actuator moves the probe to the surface and back. Finally, our prototype of an ultrasonic probe with a linear actuator was installed on a magnet-type climbing robot to demonstrate its functionality in a practical application regarding an oil storage tank inspection system. The prototype achieved a measurement success rate of 65.9% and an average error of 0.7% compared to a reference thickness. This article details the design and development of the ultrasonic probe with a linear actuator to enable the probe to make contact with the surface. It then details the experimental results and evaluation of metal thickness measurement performed using the prototype and the climbing robot.","url":"https://doi.org/10.3390/act14060299","authors":["Yuki Nishimura","Cheng Wang","Wei Song"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-19T05:08:39Z","doi":"10.3390/act14060299","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.1109/tmrb.2025.3583152","name":"A Variable Stiffness Pneumatic Actuator for Minimally Invasive Surgery Devices","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tmrb.2025.3583152","authors":["Vani Virdyawan","Muhammad Aldian Salman","Nicolaas George Edward","Sandro Mihradi","Indrawanto"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-25T14:26:08Z","doi":"10.1109/tmrb.2025.3583152","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.378Z"},{"id":"doi:10.37934/spaset.1.1.7683a","name":"Computer-Based FTC System for Flexible Robot Manipulator System under Actuator and Sensor Faults","source":"crossref","abstract":"Industry demand high reliability in their system especially in a hazardous working environment.

Many linkage configurations were considered in designing this robot, and one without continuous singularities was selected. The robot stride consists of an extension phase and a contraction phase. In each phase, one foot is stationary, and one foot is moving. When each of the feet is in motion, the ground reaction force is assumed to be zero. The motion planning of the robot is designed so that the velocity and acceleration of each of the robot’s rigid bodies is zero at the beginning and end of each movement phase. In the future, this robot will be prototyped using mostly 3D printed components, and its control algorithm will be refined during testing.","url":"https://doi.org/10.1115/detc2023-115207","authors":["Joel Quarnstrom","Yujiang Xiang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-11-21T17:55:52Z","doi":"10.1115/detc2023-115207","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.4236/wsn.2012.410034","name":"Zigbee Based Wireless Sensor and Actuator Network for Service Robot Intelligent Space","source":"crossref","abstract":"","url":"https://doi.org/10.4236/wsn.2012.410034","authors":["Baoye Song","Xiao Lu","Xingzhen Bai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-10-31T02:34:57Z","doi":"10.4236/wsn.2012.410034","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/tro.2014.2329998","name":"A Stiffness Estimator for Agonistic–Antagonistic Variable-Stiffness-Actuator Devices","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tro.2014.2329998","authors":["Tomas Menard","Giorgio Grioli","Antonio Bicchi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-07-18T18:41:20Z","doi":"10.1109/tro.2014.2329998","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/lra.2024.3418268/mm3","name":"Continuously Variable Transmission and Stiffness Actuator Based on Actively Variable Four-Bar Linkage for Highly Dynamic Robot Systems_supp1-3418268.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3418268/mm3","authors":["Seokhwan Jeong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-25T17:01:39Z","doi":"10.1109/lra.2024.3418268/mm3","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/robot.2006.1641969","name":"A snake-like swimming robot using IPMC actuator/sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.2006.1641969","authors":["N.

However, DRL methods often require extensive training time, and the resulting policies do not generalize well to different robot configurations or varying numbers of actuators. In this article, we introduce a novel DRL approach for controlling CDPRs that does not depend on the specific robot configuration. Our method trains an actuator-level policy that controls each motor to achieve its target cable length, in contrast to conventional DRL approaches that learn to control the entire robot to reach a desired end-effector position. To the best of our knowledge, this is the first work to apply DRL to control CDPRs using an actuator-level policy. This approach offers two main advantages: (i) a single shared policy can be applied to any CDPR configuration, regardless of actuator count, and (ii) reliance on inverse kinematics, avoiding the more challenging forward kinematics problem. Training is performed in simulation, and the learned policy is successfully transferred to a real CDPR. Experimental results show that the actuator-level policy (ALP) surpasses traditional reinforcement learning methods in both robustness and precision.","url":"https://doi.org/10.2139/ssrn.6730496","authors":["Abir Bouaouda","Mohamed Boutayeb","François Charpillet","Dominique Martinez","Rémi Pannequin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-09T06:30:51Z","doi":"10.2139/ssrn.6730496","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1177/01423312221149241","name":"Joint actuator fault estimation and localization under Round-Robin protocol for wheeled mobile robot","source":"crossref","abstract":"In this paper, the joint actuator fault estimation (AFE) and the wheeled mobile robot (WMR) localization under the Round-Robin protocol (RRP) problems are concerned. In order to complete the joint AFE and the WMR localization, a nominal joint system is constructed, which consists of the drive subsystem and WMR localization subsystem. In the drive subsystem of the WMR, the DC motor is used as an actuator to drive the WMR. When the faults occur, the performance of the actuator will be degraded, and the mobility of the WMR will be affected. In order to maintain a satisfactory mobility of the WMR, the faults need to be estimated timely such that some appropriate decisions or remedies can be made. In the WMR localization subsystem, for saving the network resources, the RRP is introduced to schedule the transmission of sensor measurements used for the WMR localization. The purpose of this paper is, by designing a time-varying filter for the constructed joint nominal system, to ensure the filtering error to meet the given H ∞ performance requirement, such that the joint AFE and the WMR localization can be achieved simultaneously. Specifically, the sufficient condition is derived first and then the desired filter gain is designed by the recursive linear matrix inequality technology. Finally, a simulation experiment is conducted to certify the usefulness of the proposed algorithm.","url":"https://doi.org/10.1177/01423312221149241","authors":["Yanyang Lu","Hamid Reza Karimi","Naixin Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-01-27T07:44:37Z","doi":"10.1177/01423312221149241","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.794Z"},{"id":"doi:10.1109/lra.2024.3418268/mm2","name":"Continuously Variable Transmission and Stiffness Actuator Based on Actively Variable Four-Bar Linkage for Highly Dynamic Robot Systems_supp3-3418268.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3418268/mm2","authors":["Seokhwan Jeong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-25T17:01:39Z","doi":"10.1109/lra.2024.3418268/mm2","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/iros.2012.6385500","name":"A novel design of a robot that can jump and roll with a single actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros.2012.6385500","authors":["Thanhtam Ho","Sangyoon Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-01-02T23:15:05Z","doi":"10.1109/iros.2012.6385500","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/icma.2013.6617925","name":"Characterization and modeling of a pneumatic actuator for a soft continuum robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icma.2013.6617925","authors":["Gang Chen","Ling Fu","Minh Tu Pham","Tanneguy Redarce"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-10-10T19:27:29Z","doi":"10.1109/icma.2013.6617925","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/tro.2010.2052398","name":"The Actuator With Mechanically Adjustable Series Compliance","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tro.2010.2052398","authors":["Jonathan W Hurst","Joel E Chestnutt","Alfred A Rizzi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-07-20T20:19:33Z","doi":"10.1109/tro.2010.2052398","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1115/1.4065393","name":"A Three-Actuator Cable-Driven Parallel Robot With a Rectangular Workspace","source":"crossref","abstract":"Abstract In the realm of cable-driven parallel robots (CDPRs), the conventional notion entails that each cable is directly actuated by a corresponding actuator, implying a direct relationship between the number of cables and actuators. However, this article introduces a paradigm shift by contending that the number of cables should be contingent upon the desired workspace, while the number of actuators should align with the robot’s degrees-of-freedom (DoF). This novel perspective leads to an unconventional design methodology for CDPRs. Instead of commencing with the number of actuators and cables in mind, we propose an approach that begins with defining the required workspace shape and determines the requisite number of cables. Subsequently, an actuation scheme is established where each actuator can drive multiple cables. This process entails the formulation of a transmission matrix that captures the interplay between actuators and cables, followed by the mechanical implementation of the corresponding cable-pulley routing. To illustrate this approach, we provide an example involving a 2-DoF CDPR aimed at covering a rectangular workspace. Notably, the resulting wrench-closure workspace (WCW) and wench-feasible workspace (WFW) of the proposed designs exhibit favorable comparisons to existing CDPRs with more actuators.","url":"https://doi.org/10.1115/1.4065393","authors":["Foroogh Behroozi","Ramin Mersi","Antoine Benoist","Ru Ying Yong","Philippe Cardou","Stéphane Caro"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-23T15:14:38Z","doi":"10.1115/1.4065393","addedAt":"2026-08-31T06:34:12.378Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1109/roman.2004.1374826","name":"Linear actuator for high-resolution tactile display","source":"crossref","abstract":"","url":"https://doi.org/10.1109/roman.2004.1374826","authors":["M.

This study focuses on an articulated robot utilizing a water-based Electro-Hydraulic Actuator (EHA). The Denavit–Hartenberg (D–H) representation was employed to relate the rotational angles and the end-effector’s location, facilitating the design of the actuators. The maximum required torques for joints 2 and 3, responsible for lifting for 12 s, were calculated under quasi-static and dynamic loading conditions. The results showed that the maximum required torques were 126.67 Nm and 58.86 Nm for joint 2 and 3, respectively. The maximum torque for joint 2 occurs when the pitch links are fully extended, whereas the maximum torque for joint 3 occurs when the third link is parallel to the ground. The torques, due to the inertia and Coriolis dynamic terms, were also calculated and found to be lower than those required for the gravitational term. Various maneuvering scenarios, along with Ansys Motion simulation, were analyzed for the verification of the results. Based on the calculated maximum torques, the linear actuators of the EHA were designed. The heavy-duty cobot can be built with the developed actuator proposed in this paper. The total weight of the entire frame was measured to be 14.59 kg, resulting in a high Payload/Weight (P/W) ratio of 1.37. In conclusion, the robot was made lighter and can operate more efficiently, particularly for heavy loads up to 20 kg.","url":"https://doi.org/10.3390/act13110451","authors":["Ha-Gwon Song","Dong-Won Lim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-11T11:34:11Z","doi":"10.3390/act13110451","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.14733/cadaps.2024.791-806","name":"Design and Integration of a Low-Back Exoskeleton: A 3D-Printed Cycloidal Drive Actuator for Flexible Human-Robot Interaction","source":"crossref","abstract":"","url":"https://doi.org/10.14733/cadaps.2024.791-806","authors":["Gabriele Gambirasio","Mattia Pesenti","Mattia Panzenbeck","Marta Gandolla","Loris Roveda","Mario Covarrubias"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-01-12T22:44:52Z","doi":"10.14733/cadaps.2024.791-806","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1177/01423312241227096","name":"Research on force/position switching control of servo actuator for hydraulically driven joint robot","source":"crossref","abstract":"According to the robot’s walking motion characteristics, the position/force switching control is studied to realize the segmental control of the robot stroke. This stroke is controlled by position when the foot end of the robot descends from the suspension to the ground. To avoid excessive contact force when the robot touches the ground, force control is carried out when the foot touches the ground. Due to the force and position control methods and control parameters of the hydraulic quadruped robots are different, the precise mathematical model for the joint position control and joint force control of the leg joints of the hydraulic quadruped robot is established using the system identification method. A fuzzy multi-model switching algorithm is proposed to solve the problem of jumping and jitter of system parameters in the process of force/position switching. Through simulation and prototype experiments, fuzzy multi-model switching is compared with direct switching and multi-model switching, and the switching effect of the algorithm is verified.","url":"https://doi.org/10.1177/01423312241227096","authors":["Bingwei Gao","Yongkang Wang","Wenlong Han","Shilong Xue"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-12T04:13:16Z","doi":"10.1177/01423312241227096","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1145/3674746.3674750","name":"A Desktop Bilateral Rehabilitation Robot Driven by Nonlinear Rotary Series Elastic Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1145/3674746.3674750","authors":["Maozeng Zhang","Huijun Li","Ke Shi","Ye Li","Aiguo Song"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-21T18:26:08Z","doi":"10.1145/3674746.3674750","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1007/978-981-97-5423-6_48","name":"Upper-Limb Exoskeleton Robot Design Driven by a Pneumatic Artificial Muscle Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-97-5423-6_48","authors":["Abhinav Punjabi","Garima Bisen","Pratiksha Kumari","Riya Jain","Usha Meel","Deepak Kumar"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-05T07:02:31Z","doi":"10.1007/978-981-97-5423-6_48","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1299/jsmemdt.2024.23.1b2-5","name":"Small Robot Vehicle Using Omni-Directional Actuator and Tripod Parallel Mechanism","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmemdt.2024.23.1b2-5","authors":["Yutaka TANAKA","Tomomasa NAKAMURA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-24T22:17:50Z","doi":"10.1299/jsmemdt.2024.23.1b2-5","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.3390/biomimetics9080488","name":"Multimodal Resonances of a Rectangular Planar Dielectric Elastomer Actuator and Its Application in a Robot with Soft Bristles","source":"crossref","abstract":"Inspired by the fact that flying insects improve their power conversion efficiency through resonance, many soft robots driven by dielectric elastomer actuators (DEAs) have achieved optimal performance via first-order modal resonance. Besides first-order resonance, DEAs contribute to multiple innovative functions such as pumps that can make sounds when using multimodal resonances. This study presents the multimodal resonance of a rectangular planar DEA (RPDEA) with a central mass bias. Using a combination of experiments and finite element modeling (FEM), it was discerned that under a prestretch of 1.0 × 1.1, the first-, second-, and third-order resonances corresponded to vertical vibration, rotation along the long axis, and rotation along the short axis, respectively. In first-order resonance, superharmonic, harmonic, and subharmonic responses were activated, while only harmonic and subharmonic responses were observed in the second- and third-order resonances. Further investigations revealed that prestretching tended to inhibit third-order resonance but could elevate the resonance frequencies of the first and second orders. Conveniently, both the experimental and FEM results showed that the frequencies and amplitudes of the multimodal resonances could be tuned by adjusting the amplitudes of the excitation signals, referring to the direct current (DC) amplitude and alternating current (AC) amplitude, respectively. Moreover, instead of linear vibration, we found another novel approach that used rotation vibration to drive a robot with soft bristles via hopping locomotion, showcasing a higher speed compared to the first-order resonance in our robot.","url":"https://doi.org/10.3390/biomimetics9080488","authors":["Yangyang Du","Xiaojun Wu","Dan Wang","Futeng Zhao","Hua Hu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-13T10:54:54Z","doi":"10.3390/biomimetics9080488","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1109/lra.2024.3477096","name":"Coaxial Integrated Tendon-Driven Actuator: Design, Modeling, Control, and Performance Analysis","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3477096","authors":["Di Zhao","Xinbo Wang","Lei Ren","Kunyang Wang","Luquan Ren"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-09T17:56:54Z","doi":"10.1109/lra.2024.3477096","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1109/lra.2024.3418268","name":"Continuously Variable Transmission and Stiffness Actuator Based on Actively Variable Four-Bar Linkage for Highly Dynamic Robot Systems","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3418268","authors":["Jungwoo Hur","Hangyeol Song","Seokhwan Jeong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-24T20:10:31Z","doi":"10.1109/lra.2024.3418268","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1002/rnc.7412","name":"Adaptive neural tracking control for flexible joint robot including hydraulic actuator dynamics with disturbance observer","source":"crossref","abstract":"Abstract In this paper, a disturbance observer‐based adaptive neural backstepping integral sliding mode control (BISMC) is developed for a flexible joint robot (FJR) with the integration of an adjustable stiffness rotary actuator (ASRA). This system suffers from unknown system dynamics, external disturbance, and the influence of variable stiffness, which is a challenge for achieving precision tracking performance. Considering the lumped disturbances in FJR generated by the hydraulic system and the stiffness modulation of the ASRA, we investigate the structural dynamics nonlinear model of the FJR system, including hydraulic actuator dynamics. While other linear control strategies are applied for the FJR, the proposed controller uses BISMC, neural networks (NN), and nonlinear disturbance observers to deal with the disadvantages mentioned above. Radial basis function neural networks (RBFNN) are designed to tackle unknown nonlinear functions, and the disturbance observers are introduced to compensate for the influence of the variable stiffness, disturbance, and the approximation error caused by NN. Simulations and experiments are independently implemented to demonstrate the effectiveness and feasibility of the proposed controller. Results exhibit that the integral absolute error‐index is reduced by 20.4% when the proposed method is deployed for the experiment with a multistep trajectory.","url":"https://doi.org/10.1002/rnc.7412","authors":["Van Du Phan","Cong Phat Vo","Kyoung Kwan Ahn"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-05-15T23:44:10Z","doi":"10.1002/rnc.7412","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1109/robot61475.2024.10796939","name":"2024 7th Iberian Robotics Conference (ROBOT)","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot61475.2024.10796939","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-23T19:10:37Z","doi":"10.1109/robot61475.2024.10796939","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1088/1361-665x/ad54ad/v3/review1","name":"Review for \"Permanently magnetized elastomer rotating actuator using traveling waves\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/1361-665x/ad54ad/v3/review1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-06T17:19:30Z","doi":"10.1088/1361-665x/ad54ad/v3/review1","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:15.497Z"},{"id":"doi:10.1088/1361-665x/ad54ad/v2/review2","name":"Review for \"Permanently magnetized elastomer rotating actuator using traveling waves\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/1361-665x/ad54ad/v2/review2","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-06T17:19:30Z","doi":"10.1088/1361-665x/ad54ad/v2/review2","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:15.497Z"},{"id":"doi:10.2139/ssrn.5007140","name":"Fault Tolerant Position Control of Soft Bending Actuator in the Presence of Actuator Leakage","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5007140","authors":["Sina Rabiei","Sajad Sadeghi Nalkenani","Iman Sharifi","Heidar Ali Talebi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-05T01:13:36Z","doi":"10.2139/ssrn.5007140","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1088/1361-665x/ad54ad/v1/review1","name":"Review for \"Permanently magnetized elastomer rotating actuator using traveling waves\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/1361-665x/ad54ad/v1/review1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-06T17:19:30Z","doi":"10.1088/1361-665x/ad54ad/v1/review1","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:19.859Z"},{"id":"doi:10.1142/9789811282850_0007","name":"Robot Learning","source":"crossref","abstract":"","url":"https://doi.org/10.1142/9789811282850_0007","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-03-01T02:32:48Z","doi":"10.1142/9789811282850_0007","addedAt":"2026-08-31T06:34:12.393Z","updatedAt":"2026-08-31T06:34:12.393Z"},{"id":"doi:10.1002/rnc.7190","name":"Nonsingular predefined‐time dynamic surface control of a flexible‐joint space robot with actuator constraints","source":"crossref","abstract":"Abstract To achieve predefined‐time trajectory tracking control of a flexible‐joint space robot(FJSR) with actuator constraints, a nonsingular predefined‐time dynamic surface control scheme is developed. The input saturation caused by actuator constraints is addressed via the designed predefined‐time anti‐saturation compensator. On this basis, two different control laws are designed for such high‐order nonlinear systems by utilizing the backstepping technique, and a novel nonlinear filter is constructed to filter the virtual control signals, thus avoiding the “differential expansion” phenomenon. Moreover, a singularity‐free auxiliary function is designed to solve the singularity issue generated by the derivative of fractional power terms in the predefined‐time control algorithm framework. The closed‐loop system is proven to be semi‐globally predefined‐timely uniformly ultimately bounded (SGPTUUB) via constructing the suitable Lyapunov function. The difference and effectiveness of the two designed control laws are illustrated by the conducted simulations. Both of them allow the FJSR system to track the desired trajectory in a reasonably predefined time.","url":"https://doi.org/10.1002/rnc.7190","authors":["Liaoxue Liu","Xiutao Gu","Lu Wang","Jian Guo","Yu Guo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-01-09T05:00:21Z","doi":"10.1002/rnc.7190","addedAt":"2026-08-31T06:34:12.394Z","updatedAt":"2026-08-31T06:34:13.657Z"},{"id":"doi:10.5573/jsts.2024.24.4.316","name":"Electrostatic Force Simulation Comparison of Tilted Plate Actuator and Conventional Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.5573/jsts.2024.24.4.316","authors":["Sieun Lee","Yunyoung Jang","Jong-Pal Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-09-03T21:06:51Z","doi":"10.5573/jsts.2024.24.4.316","addedAt":"2026-08-31T06:34:12.394Z","updatedAt":"2026-08-31T06:34:12.394Z"},{"id":"doi:10.1109/fuzz.2003.1209379","name":"Intelligent control of a multi-actuator mobile robot with competing factors","source":"crossref","abstract":"","url":"https://doi.org/10.1109/fuzz.2003.1209379","authors":["J.T.

Current devices display limitations that require trade-offs among cortical surface coverage, spatial electrode resolution, aesthetic, and risk consequences and often limit the use of the mapping technology to the operating room. In this work, we report on a scalable technique for the fabrication of large-area soft robotic electrode arrays and their deployment on the cortex through a square-centimeter burr hole using a pressure-driven actuation mechanism called eversion. The deployable system consists of up to six prefolded soft legs, and it is placed subdurally on the cortex using an aqueous pressurized solution and secured to the pedestal on the rim of the small craniotomy. Each leg contains soft, microfabricated electrodes and strain sensors for real-time deployment monitoring. In a proof-of-concept acute surgery, a soft robotic electrode array was successfully deployed on the cortex of a minipig to record sensory cortical activity. This soft robotic neurotechnology opens promising avenues for minimally invasive cortical surgery and applications related to neurological disorders such as motor and sensory deficits.","url":"https://doi.org/10.1126/scirobotics.add1002","authors":["Sukho Song","Florian Fallegger","Alix Trouillet","Kyungjin Kim","Stéphanie P.

The swimming speed of the fish robot was measured for four different tail fin areas. The drag of the fish robot was estimated by experiment and computational fluid dynamics (CFD) simulation. For drag measurement, we have presented an apparatus to measure relatively small drag by using a high speed camera. The measured drag agreed well with the calculated one by the CFD. We have also suggested a thrust measurement apparatus, where we can ignore effect of vibratory motion of the system. The thrust of the fish robot was increased about 11% due to the applied compressive force on the piezoceramic actuators. However, the drag of the fish robot was also increased due to increment of the cross section area.","url":"https://doi.org/10.32508/stdj.v17i4.1526","authors":["Sang Nguyen Quang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-01-20T18:23:11Z","doi":"10.32508/stdj.v17i4.1526","addedAt":"2026-08-31T06:34:12.475Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.21595/vp.2023.23355","name":"Dynamic modeling and analysis of a vibration-driven robot driven by a conical dielectric elastomer actuator","source":"crossref","abstract":"This article aims to establish a theoretical model of a vibration-driven robot driven by a conical dielectric elastomer actuator and analyze its characteristics, in order to make up for the lack of theoretical model construction and parameter evolution analysis for this type of robot.

The bearing stiffness calculation can be obtained from Hertzian contact theory. From a design standpoint, given the bearing stiffness, the target stiffness of the actuator shell structure and output plate may be an order higher than that of the principal bearing. This paper evaluates and compares the relationship between the stiffness of the shell structure and principal bearing as well as between the stiffness of the output-plate and principal bearing. The principal bearing for the actuator could be the crossed roller bearing (CRB), four-point bearing (FPB), or a tapered roller bearing (TRB) because they best accommodate the combined radial, axial, and moment loads. Also, the bearing weight and assembled weight (shell structure + principal bearing + output-plate) required to obtain appropriate stiffness can be evaluated based on the stiffness of these adjacent structures which hold the principal bearing. Finally, the shortest possible force path passing through the principal bearing from the shell to the output plate makes it possible to maximize actuator stiffness and reduces other negative effects.","url":"https://doi.org/10.1115/detc2011-48030","authors":["Hoon Lee","Delbert Tesar"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-06-13T18:30:25Z","doi":"10.1115/detc2011-48030","addedAt":"2026-08-31T06:34:12.475Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/robot.1995.525578","name":"A new learning control of robot manipulators in the presence of actuator dynamics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1995.525578","authors":["C.

In-pipe soft robots made of highly deformable materials have been proposed to meet the needs, yet most of those comprise multiple segments and require multiple actuators controlled independently, resulting in less compact structures and more demanding control schemes. In this study, we harness the highly nonlinear buckling of elastic ribbons and bioinspired artificial muscles to significantly enhance the crawling capability of a single-actuator soft robot. Our prototype robot consists of a McKibben pneumatic actuator surrounded by three longitudinally arranged elastic ribbons. These tailored ribbons are three-dimensional (3D) printed and can be buckled into highly deformed 3D shapes upon inflation of the actuator. First, we show that the robot exhibits strong anisotropic friction when fully buckled. Then, we demonstrate that by simple open-loop on/off control, our robot achieves robust crawling in horizontal, vertical, bent pipes and even wet pipes partially or filled with water. It can also adapt to pipes with some variations in diameter. Using only one actuator lowers the complexity of robot structure and pneumatic system, offering high potential for new applications at different scales.","url":"https://doi.org/10.1089/soro.2021.0220","authors":["Ying Lin","Yi-Xian Xu","Jia-Yang Juang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-05-11T11:39:38Z","doi":"10.1089/soro.2021.0220","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1109/tmech.2023.3339170/mm2","name":"A 7 cm-Scale Spherical Underwater Robot Using Piezoelectric Double-Jet Actuator for Deep-Sea Environment_supp3-3339170.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tmech.2023.3339170/mm2","authors":["Kai Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-29T14:48:52Z","doi":"10.1109/tmech.2023.3339170/mm2","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1109/tmech.2023.3339170/mm1","name":"A 7 cm-Scale Spherical Underwater Robot Using Piezoelectric Double-Jet Actuator for Deep-Sea Environment_supp2-3339170.pdf","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tmech.2023.3339170/mm1","authors":["Kai Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-29T14:48:52Z","doi":"10.1109/tmech.2023.3339170/mm1","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:19.860Z"},{"id":"doi:10.1115/1.4035237","name":"Global Output Feedback Finite-Time Regulation of Robot Manipulators Under Actuator Constraints","source":"crossref","abstract":"In this paper, the finite-time regulation problem of robot manipulators under saturated actuator inputs with position measurements only is addressed.

The challenge lies in the design of a fast, robust, switchable adhesion actuator to easily attach and detach the vertical surfaces. Here, we propose a new design of pneumatic-actuated bioinspired soft adhesion actuator working both on ground and under water. It is composed of extremely soft bilayer structures with an embedded spiral pneumatic channel resting on top of a base layer with a cavity. Rather than the traditional way of directly pumping air out of the cavity for suction in hard polymer-based adhesion actuator, we inflate air into the top spiral channel to deform into a stable 3D dome shape for achieving negative pressure in the cavity. The characterization of the maximum shear adhesion force of the proposed soft adhesion actuator shows strong and rapid reversible adhesion on multiple types of smooth and semi-smooth surfaces. Based on the switchable adhesion actuator, we design and fabricate a novel load-carrying amphibious climbing soft robot (ACSR) by combining with a soft bending actuator. We demonstrate that it can operate on a wide range of foreign horizontal and vertical surfaces including dry, wet, slippery, smooth, and semi-smooth ones on ground and also under water with certain load-carrying capability. We show that the vertical climbing speed can reach about 286 mm/min (1.6 body length/min) while carrying over 200 g object (over 5 times the weight of ACSR itself) during climbing on ground and under water. This research could largely push the boundaries of soft robot capabilities and multifunctionality in window cleaning and underwater inspection under harsh environment.","url":"https://doi.org/10.1089/soro.2017.0133","authors":["Yichao Tang","Qiuting Zhang","Gaojian Lin","Jie Yin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-06-29T09:51:11Z","doi":"10.1089/soro.2017.0133","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1109/tmech.2023.3339170/mm3","name":"A 7 cm-Scale Spherical Underwater Robot Using Piezoelectric Double-Jet Actuator for Deep-Sea Environment_supp1-3339170.docx","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tmech.2023.3339170/mm3","authors":["Kai Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-29T14:48:52Z","doi":"10.1109/tmech.2023.3339170/mm3","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/etfa.2008.4638512","name":"Modeling of magneto rheological fluid actuator enabling safe human-robot interaction","source":"crossref","abstract":"","url":"https://doi.org/10.1109/etfa.2008.4638512","authors":["Rehan M.

Faults encountered during their tasks may cause the task to be interrupted or failed completely. In the active fault tolerant control methods, it is very important not only to detect the faults that occur in the robot, but also to isolate these faults to develop a fault recovery strategy that is suitable for that specific type of fault. This study aims to develop a model-based fault detection and isolation method for wheel slippage and motor performance degradation that may occur in wheeled mobile robots. Design/methodology/approach In the proposed method, wheel speeds can be estimated via the dynamic model of the mobile robot, which includes a friction model between the wheel and the ground. Four residual signals are obtained from the differences between the estimated states and the measured states of the mobile robot. Mobile robot’s faults are detected by using these signals. Also, two different residual signals are generated from the calculation of the traction forces with two different procedures. These six residual signals are then used to isolate possible wheel slippage and performance degradation in a motor. Findings The proposed method for diagnosing wheel slip and performance degradation in motors are tested by moving the robot in various directions. According to the data obtained from the test results, a logic table is created to isolate these two faults from each other. Thanks to the created logic table, slippage in any wheel and performance degradation in any motor can be detected and isolated. Originality/value Two different recovery strategies are needed to recover temporary wheel slippage and permanent motor faults. Therefore, it is important to isolate these two faults that create similar symptoms in robot’s general movement. Thanks to the method proposed in this study, it is not only possible to isolate the slipping wheel with respect to the non-slipping wheels or to isolate the faulty motor from the non-faulty ones, but also to isolate these two different fault types from each other.","url":"https://doi.org/10.1108/ir-01-2022-0001","authors":["Osman Nuri Şahin","Mehmet İsmet Can Dede"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-05-16T07:16:21Z","doi":"10.1108/ir-01-2022-0001","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1007/s10846-017-0741-0","name":"Analysis of Dynamic Characteristics of Water Hydraulic Rotating Angle Self-Servo Robot Joint Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s10846-017-0741-0","authors":["Lin Jiang","Zhichao Zhu","Honghai Liu","Jianyang Zhu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-11-16T06:41:45Z","doi":"10.1007/s10846-017-0741-0","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.20965/jrm.1993.p0332","name":"Design and Positioning Control of Microhead Actuator for Optical Disk Storage System  (Design Guidelines for a Collocation-Type Actuator)","source":"crossref","abstract":"This paper describes the mechanical design of a microhead actuator for disk storage systems and its positioning control method.

Design/methodology/approach The hybrid actuator controller has a module to estimate instantaneous changes in inertia and a blending algorithm that adjusts input signals to the motor and the brake so that together, as a hybrid actuator, they can achieve a fast, stiff position response without overshoot. The control logic implemented in the controller is derived from the kinematics of the system. For the blending algorithm, two separate cases are explored in which the user has the option to either utilize the full‐braking capacity or specify a safe deceleration limit for the system. Findings The blending algorithm enables the system to operate nearly twice as fast as the motor‐only case without any overshoot or oscillations. The controller can reject inertial load changes and significant external disturbances. Originality/value Such hybrid actuators along with the developed controller can be used in robotics and automation to increase the system accuracy and operational speed resulting in higher production rates. In addition, much stiffer haptic force feedback interfaces for virtual reality applications can be designed with smaller actuators. The blending algorithm provides considerable improvements and uses a physics‐based simple and easy‐to‐implement structure.","url":"https://doi.org/10.1108/01439911111154063","authors":["Berk Gonenc","Hakan Gurocak"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-08-13T07:06:30Z","doi":"10.1108/01439911111154063","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1016/s0007-8506(07)62605-5","name":"Development of Flexible Actuator Controller for Advanced Machine Tool and Robot Control","source":"crossref","abstract":"","url":"https://doi.org/10.1016/s0007-8506(07)62605-5","authors":["K.

To handle the issue, in this paper a pneumatic force-controlled actuator was developed to keep the normal contact force between the polishing tool and the workpiece constant during the robotic polishing process. The force-controlled actuator is configured with a double-acting cylinder as the driving element, and two electrical proportional valves are used to control the output force by adjusting the pressure difference between the two air chambers of the cylinder. In this case, a small contact force can be exactly achieved, and the cylinder can always work within the optimal pressure range. In order to judge the stability of the system and reduce the commissioning time of the force-controlled actuator, a mathematical model of the force-controlled actuator is established. Meanwhile, for eliminating the influence of the gravity of the polishing tool on the contact force control, a gravity compensation algorithm is also given according to the roll-pitch-yaw (RPY) angle calculation method. Since there are some nonlinear factors in the operation of the force-controlled actuator, a fuzzy proportion-integral-derivative (PID) control strategy is adopted without steady-state errors. Finally, the polishing experiment of a complex curved plexiglass part was carried out by using the robot automatic polishing system. The experimental results show that the contact force control effect of the force-controlled actuator meets the processing requirements, and the curved plexiglass part has good surface quality and optical performance after polishing.","url":"https://doi.org/10.3390/machines11040446","authors":["Xinyu Zhang","Yuwen Sun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-04-03T02:32:27Z","doi":"10.3390/machines11040446","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/iros.2011.6048699","name":"Avoiding steering actuator saturation in off-road mobile robot path tracking via predictive velocity control","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros.2011.6048699","authors":["O.

This paper presents an improved version of the assisted navigation algorithm based on the concept of “credit field”. The main aim of the proposed algorithm is to reduce and balance the energy consumption among the static sensor nodes when running the algorithm to manage the presence of obstacles and adversary areas, thus extending the lifetime of WSARNs. The algorithm has been tested on a hybrid sensor network that employs Mica2 Motes as static sensor nodes and Lego Mindstorms robots integrated with a Stargate board developed by Crossbow as mobile nodes.","url":"https://doi.org/10.17762/ijcnis.v10i2.3429","authors":["Franco Frattolillo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-07-18T08:50:00Z","doi":"10.17762/ijcnis.v10i2.3429","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/coase.2008.4626500","name":"Actuator networks for navigating an unmonitored mobile robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/coase.2008.4626500","authors":["Jeremy Schiff","Anand Kulkarni","Danny Bazo","Vincent Duindamx","Ron Alterovitz","Dezhen Song","Ken Goldberg"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-09-24T13:55:06Z","doi":"10.1109/coase.2008.4626500","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/transducers.2011.5969634","name":"Three-axis tactile display using PDMS pneumatic actuator for robot-assisted surgery","source":"crossref","abstract":"","url":"https://doi.org/10.1109/transducers.2011.5969634","authors":["Eunhyup Doh","Hyungkew Lee","Joonah Park","Kwang-Seok Yun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-08-03T21:54:47Z","doi":"10.1109/transducers.2011.5969634","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/robio.2006.340322","name":"Development of Elevator Control Surface for Small Air Robot Using Piezoceramic Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio.2006.340322","authors":["Kwang Joon Yoon","Hery Setiawan","Ngoc-Trung Nguyen","Hoon Cheol Park"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-04-17T20:16:25Z","doi":"10.1109/robio.2006.340322","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1163/016918610x496937","name":"Novel Energy Transfer Mechanism in a Running Quadruped Robot with One Actuator per Leg","source":"crossref","abstract":"","url":"https://doi.org/10.1163/016918610x496937","authors":["Nicholas Cherouvim","Evangelos Papadopoulos"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-04-29T00:57:24Z","doi":"10.1163/016918610x496937","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.2478/jee-2019-0019","name":"Reconfigurable control of flexible joint robot with actuator fault and uncertainty","source":"crossref","abstract":"Abstract This paper presents the fault tolerant control (FTC) of a flexible joint robot using singular perturbation method in order to compensate for the lost performance due to the occurrence of actuator fault and the uncertainty. This FTC is based on Lyapunov redesign principle. The singular perturbation method is used to reduce the dynamic model of the flexible joint robot in a fast and slow subsystem. The time scale reduction of the flexible joint model is carried out when their joint stiffness is large enough and the singular perturbation parameter is set to zero. The fault-tolerant control structure in this paper is based on two parts. The first term described the composite control for the system without defect and without uncertainty which represents the sum between slow and fast controllers. While the second term of the fault tolerant command describes additive control designed to compensate for the fault effect of the actuator on the uncertain system. The additive approach is based on the Lyapunov theorem, which guarantees asymptotic stability despite the presence of actuator defects and the parametric uncertainty. The theoretical results are applied on a robot manipulator with a single flexible joint.","url":"https://doi.org/10.2478/jee-2019-0019","authors":["Aymen Elghoul","Adel Tellili","Mohamed Naceur Abdelkrim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-05-14T05:31:19Z","doi":"10.2478/jee-2019-0019","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/apccas.2002.1115114","name":"Feedback error learning control using adaptive fuzzy network to control one linear actuator hopping robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/apccas.2002.1115114","authors":["S.

This research is different than usual control algorithm. It proposes a universal algorithm for sensorless collision detection of robot actuator faults to enhance the security of the robot. On the basis of the dynamic model, a classical friction model to ensure the accuracy of the whole dynamic model is introduced. This collision detection algorithm can conduct without any external sensors or acceleration and realize the real-time detection just needs to measure the motor current and the location information from the encoder of the robot joint. The value of external torque τ ext was used to compare with the threshold to detect the collision. After using the proposed collision detection method, the two rotational (2R) planar manipulators can detect the slight collision reliably. The experimental results and performance comparisons show that this sensorless collision detection algorithm is simple and effective. It can be promoted to any other type of robot arm with more degrees of freedom.","url":"https://doi.org/10.1177/1687814017740710","authors":["Saixuan Chen","Minzhou Luo","Feng He"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-01-06T04:36:01Z","doi":"10.1177/1687814017740710","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1016/j.jnca.2016.01.013","name":"Towards wireless sensor, actuator and robot networks: Conceptual framework, challenges and perspectives","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.jnca.2016.01.013","authors":["Daniel-Ioan Curiac"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-01-28T15:21:32Z","doi":"10.1016/j.jnca.2016.01.013","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/tro.2012.2199649","name":"Design and Control of a Variable Stiffness Actuator Based on Adjustable Moment Arm","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tro.2012.2199649","authors":["Byeong-Sang Kim","Jae-Bok Song"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-05-31T18:40:44Z","doi":"10.1109/tro.2012.2199649","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.11591/ijra.v4i2.pp93-97","name":"Modification and Actuator Minimization of the Hip Leg Joint in a Bipedal Robot: A Proposed Design","source":"crossref","abstract":"In recent times, there have been numeric applications of Biped Robots. In this paper, a proposed upper leg hip design of a biped was developed taking cost reduction and optimization as factors for consideration. The proposed system introduces a novel method which consists of a vibration reduction (VR) DC stepper motor, microcontroller, microprocessor and gearing arrangement. The program in the microprocessor is so designed that it gives a fixed number of cycles/steps to the VR DC stepper motor in clockwise and thereafter in anti-clockwise direction. This turning movement can then be transmitted to the gearing system which precisely moves one upper leg when the VR DC stepper motor moves in clockwise direction, while the other upper leg remains static, and vice-versa. It has been observed that this new proposed system may reduce the cost overhead, weight and the energy consumption incurred by working on a single VR DC stepper motor while conventionally two stepper motors are used to give the motion of the two upper legs in a biped.","url":"https://doi.org/10.11591/ijra.v4i2.pp93-97","authors":["Nirmalya Tripathi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-02-10T02:38:13Z","doi":"10.11591/ijra.v4i2.pp93-97","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.4028/www.scientific.net/amm.740.161","name":"Design and Implementation of ZigBee Based Wireless Sensor and Actuator Networks in Service Robot Intelligent Space","source":"crossref","abstract":"This paper is concerned with the design and implementation of a ZigBee based wireless sensor and actuator networks, which has been applied in our service robot intelligent space successfully.

Shape memory alloys (SMA) are popular smart actuators because of its light weight, integration compatibility, ease of actuation and high power density. Inclusion of shape memory alloy actuators to the parallel robot brings in control challenges due to its nonlinearity, coupling effects and cocontraction of antagonistic pair of actuators in the mechanism in order to achieve bi directional motion. In this paper, a PID like fuzzy controller is designed and applied to a nonlinear SMA spring actuator connected to a symmetric 2 DOF miniature parallel robot. The fuzzy rules are designed from the general response plot and modified to be applied to a parallel mechanism which involves cocontraction of antagonistic actuators. The paper has also presented the control and electrical circuit design used in the experimental set up. The fuzzy control is implemented in the hardware controller with model based position feedback and tested for the trajectory tracking characteristics of the end effector with disturbances. Experimental results are presented with quantitative analysis to show the effectiveness of the proposed controller in handling nonlinearities and disturbances compared to the conventional PID control and nonlinear Sliding mode control (NSMC). The test results has demonstrated the superior nature of proposed control over other controllers in the trajectory tracking with disturbances and also linearizing the hysteresis of controlled system.","url":"https://doi.org/10.3233/jifs-202572","authors":["R.

Such a system could facilitate future control studies by reducing investigation time and implementation cost of research. It could also be used to test the performance of different strategies to control the movement of flexible joint manipulators. A hydraulic rotary servo actuator was used to simulate the action of a flexible joint robot manipulator. A challenging task since the control of angular acceleration was required. A single-rigid-link, elastic-joint robot manipulator was modeled using Matlab®. Joint flexibility parameters such as stiffness and damping, could be easily changed. This simulation could be referred to as \"function generator\" to drive the hydraulic flexible joint robot. In this study the angular acceleration was used as the input to the hydraulic rotary actuator and the objective was to make the hydraulic system follow the desired acceleration in the frequency range specified. The hydraulic system consisted of a servo valve and rotary actuator. A hydraulic actuator robot was built and tested. The results indicate that if the input signal had a frequency in the range of 5 to 15 Hz and damping ratio of 0.1, the experimental setup was able to reproduce the input signal with acceptable accuracy. Because of the inherent noise associated with the measurement of acceleration and some severe nonlinearities in the rotary actuator, control of the experimental test system using classical methods was not as successful as had been anticipated. This was a first stage in a series of studies and the results provide insight for the future application of more sophisticated control schemes.","url":"https://doi.org/10.1115/imece2006-14190","authors":["Shahram Dezfulian","Richard Burton","Reza Fotouhi","Doug Bitner"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-04-03T17:38:15Z","doi":"10.1115/imece2006-14190","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/robot.2007.364246","name":"A Bending Pneumatic Rubber Actuator Realizing Soft-bodied Manta Swimming Robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.2007.364246","authors":["Koichi Suzumori","Satoshi Endo","Takefumi Kanda","Naomi Kato","Hiroyoshi Suzuki"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-06-07T20:09:21Z","doi":"10.1109/robot.2007.364246","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/lra.2021.3084890","name":"Design and Feasibility Analysis of a Foldable Robot Arm for Drones Using a Twisted String Actuator: FRAD-TSA","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2021.3084890","authors":["Bhivraj Suthar","Seul Jung"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-10-26T20:18:25Z","doi":"10.1109/lra.2021.3084890","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/access.2024.3522076/mm1","name":"Design and Performance Analysis of a Single-Port Bidirectional Soft Actuator and Its Integration into a Versatile 3-Finger Robot Gripper_supp1-3522076.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/access.2024.3522076/mm1","authors":["SAJID NISAR"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-25T14:34:01Z","doi":"10.1109/access.2024.3522076/mm1","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/ultsym.2013.0052","name":"Piezo impact type MEMS rotary actuator and application to millimeter size AI controlled robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ultsym.2013.0052","authors":["Minami Takato","Masaki Tatani","Junichi Tanida","Shinpei Yamasaki","Ken Saito","Fumio Uchikoba"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-01-31T18:36:23Z","doi":"10.1109/ultsym.2013.0052","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/iembs.2006.4398011","name":"Quantification of Dynamic Property of Pneumatic Muscle Actuator for Design of Therapeutic Robot Control","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iembs.2006.4398011","authors":["Sivakumar Balasubramanian","He Huang","Jiping He"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-12-04T15:31:21Z","doi":"10.1109/iembs.2006.4398011","addedAt":"2026-08-31T06:34:12.476Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/robio.2009.5420392","name":"Thrust improvement of an fish robot actuated by compressed unimorph piezoelectric composite actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio.2009.5420392","authors":["Q.

The method is based on studying the characteristics of the Jacobian of the mapping function between the two displacements for a given position of the robot manipulator. The developed method provides a tool for the determination of the positioning of smart actuators to provide maximum effectiveness in eliminating high harmonics of the joint or the end-effector motion. In robots with serial and parallel kinematics chains containing nonprismatic joints, due to the associated kinematics nonlinearity, if the joint motions were synthesized with low harmonic trajectories, the end-effector trajectory would still contain high harmonics of the joint motions. Alternatively, if the end-effector motion were synthesized with low harmonic components, due to the inverse kinematics nonlinearity, the actuated joint trajectories would contain a significant high harmonic component. As a result, the operating speed and tracking precision are degraded. By integrating smart materials based actuators in the structure of robot manipulators to provide small amplitude and high frequency motions, the high harmonic component of the actuated joint and/or the end-effector motions can be significantly reduced, thereby making it possible to achieve higher operating speed and tracking precision.","url":"https://doi.org/10.1115/1.1898340","authors":["J.

However, it reduces the flexibility in controlling this robot by introducing an underactuated system. Despite being a highly complex system to control in the classical sense, Scout II reveals stable open loop behaviors by exploiting simple structured tunable controllers, which partly rely on the passive dynamics of the system. To gain better understanding of the robot dynamics, which affects the performance of the controllers, a thorough analysis of the equations of motion is conducted based on which behavior of the robot is simulated. An extensive simulation study is carried out to tune the controller for the running motion of the robot. Simulation and experimental results are studied in parallel. Actuator limitations, as the main barrier to the performance of the running controllers, are verified based on the experimental data. The measured energy efficiency of the robot places it among the most efficient legged platforms in the world.

A parallel architecture was recently proposed to generate Schönflies motions, with a CRRHHRRC[1] closed kinematic chain, that offers a functionally symmetric, single-loop, architecture, with an isostatic kinematic chain, and virtually unlimited rotatability of its gripper. This robot calls for a cylindrical drive, i.e., a two-degree-of-freedom cylindrical actuator. The thesis reports the comprehensive mechanical design, besides the kinematics and dynamics analyses of the above-mentioned mechanical system, a Schönflies-motion generator (SMG), developed at McGill University's Centre for Intelligent Machines. The analysis is intended to optimize the robot design, and examine the new ideas for speeding up its operation. Validation of the mathematical model was conducted experimentally. The results reveal the pertinence of the model.The author introduces a novel drive, dubbed the translating Π-joint, to be used as a cylindrical drive targeting the pick-and-place operations of the SMG. It is first recalled that a Π-joint is a parallelogram four-bar linkage whose coupler link undergoes pure translation w.r.t. its fixed link; moreover, all the points of the coupler link describe circles with identical radii, the common length of the two other links. The translating Π-joint is the series array of a prismatic and a Π-joint, the plane of latter being normal to the direction of the former. A realization of the translating Π-joint is the RHRRHR kinematic chain. Furthermore, four implementations are disclosed, each with unique features. In addition, the applications of this joint are studied, including two novel architectures for SMGs. The detailed design and fabrication of two prototypes based on the above-mentioned implementations is reported.In addition, the concept of virtual screw is introduced in this thesis. The virtual screw is constructed by means of cable mechanisms. The virtual screw is to be used whenever a screw joint with very large pitch is needed, in light of the limitations in the pitch sizes (a few mm/turn) available in off-the-shelf screw mechanisms. This concept arose as an alternative to the usual screw joint when designing a cylindrical differential mechanism made of lead or ball screws, with zero backlash and adjustable speed ratio. First, the virtual screw was introduced to turn the gripper of the above-mentioned SMG, originally driven by means of two coaxial right- and left-hand screws. Later, the application of the virtual screw was extended to the cylindrical drive. The conceptual and detailed designs are disclosed here.[1] C, R and H standing for cylindrical, revolute and screw joint, respectively, underlines indicating an actuated joint.","url":"https://doi.org/10.82308/3118","authors":["Karimi Eskandary, Peyman"],"tags":["Mechanical Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.82308/3118","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.48550/arxiv.2602.13762","name":"Impact-Robust Posture Optimization for Aerial Manipulation","source":"datacite","abstract":"We present a novel method for optimizing the posture of kinematically redundant torque-controlled robots to improve robustness during impacts. A rigid impact model is used as the basis for a configuration-dependent metric that quantifies the variation between pre- and post-impact velocities. By finding configurations (postures) that minimize the aforementioned metric, spikes in the robot's state and input commands can be significantly reduced during impacts, improving safety and robustness. The problem of identifying impact-robust postures is posed as a min-max optimization of the aforementioned metric. To overcome the real-time intractability of the problem, we reformulate it as a gradient-based motion task that iteratively guides the robot towards configurations that minimize the proposed metric. This task is embedded within a task-space inverse dynamics (TSID) whole-body controller, enabling seamless integration with other control objectives. The method is applied to a kinematically redundant aerial manipulator performing repeated point contact tasks. We test our method inside a realistic physics simulator and compare it with the nominal TSID. Our method leads to a reduction (up to 51% w.r.t. standard TSID) of post-impact spikes in the robot's configuration and successfully avoids actuator saturation.

The limb movements must be measured over a range of 10 mm, with a resolution of 1 nm SD (standard deviation), in experiments lasting less than 1 second. The maximum displacement speed of the limbs is 2 m/s. To fulfil the design requirements, the approach taken here is to consider that the full measurement resolution is only needed when the limb is approaching its target at low speed. The interferometer described in this thesis is capable of high accuracy fringe interpolation measurements over a range of 10 mm, with a resolution of 0.1 nm SD, in a bandwidth of 100 kHz, in a 1 second time period. For low resolution measurements when the limb is moving at high speed, the interferometer measures displacements by fringe counting. Experimental results are presented which demonstrate that the accuracy of the interferometer actually exceeds the high resolution design objective by an order of magnitude. Also, results of experiments which study the effect of noise sources (both inherent to the interferometer and from the environment) on the accuracy of the measurements are presented.

Specifically, we focus on the problem of fine end-point motion control of the robot end-effector about a nominal point where the linearized dynamics can be used. Performance is measured in the context of linear quadratic (LQ) theory. An LQ based task-space performance index for robots is proposed. Several existing robots are examined for various transient tasks using this index and for each an optimum operating location is found. A cheap control (i.e. large actuator energies) analysis is done. The limits to performance are determined (i.e. singular optimal control). An explicit solution to performance was determined and an examination of the computed-torque control law is done. An LQ based piecewise linear control (PLC) law is derived that increases the LQ gain in a piecewise-constant manner as the system trajectory converges towards the origin. This law uses a succession of invariant sets of decreasing size and for each an associated LQ gain. The formulation gives rise to an iteration function whose solution is a fixed point. The development of the PLC law led to the unveiling of a number of key properties, namely that the solution to the algebraic Riccati equation is concave with respect to both the actuator weighting and the state weighting matrices. A time-varying extension of the PLC law and an overshoot control scheme are also derived. Issues regarding state estimation problem are studied. Noise is introduced to account for model uncertainty. A transient and steady state Kalman filter analysis is done. Sensor issues are examined for robots. The Kalman filter is used to fuse joint sensor data, Cartesian position sensor data, and tachometer data to provide a single best estimate of the state and to eliminate position offsets due to model error. Finally, the effects of unmodeled dynamics, model error, and non-linearities on performance are examined. A Kalman filter is used to eliminate bias positioning errors at the robot's end-effector. Performance-uncertainty curves are generated using a numerical convex optimization method when the system is subject to parametric uncertainty. Describing functions are used to examine the backlash non-linearity.","url":"https://doi.org/10.82308/30600","authors":["Wredenhagen, G.

The starting point of the design process is to define an approximate target size and weight of the system, dictated generally by the final application. Two new generations of MFR, OS4 and CoaX are presented as design samples. Both the OS4 quadrotor and the CoaX helicopter represent a design example by following this process. The process starts by picking up an actuator from the database, estimating its performances with the propeller's model, computing the system total mass, power consumption, propulsion group cost and quality factors in hover and maximum thrust points. The targeted system for OS4 is about 500g in mass and 800mm in span while that of CoaX is 200g in mass and 300mm in span. In OS4, the choice of the propulsion group components was based on the iterative algorithm. The total system was tested in a free flight for validation. Hover operation validated all the electronics and the mechanics but the main limitation is the actuator's dynamics. This is due to the brushless sensorless technology used. Meanwhile, CoaX is able to hover, validating its structure, control electronics and the propulsion system. The encoder and the altitude sensor indicated that the robot takes-off as soon as the propellers reach about 145rad/s.

This raises a practical and underexplored question: when does legacy data begin to benefit an upgraded robot? We study this question on a wheeled humanoid platform across two hardware generations, where both the camera and gripper are changed while the overall morphology remains fixed. Contrary to the common assumption that more cross-configuration data is always helpful, we observe a grokking-like transition: legacy data remains ineffective until the upgraded configuration acquires a minimum level of task competence, after which co-training gains rise sharply before diminishing near saturation. We hypothesize that this task-dependent transition is governed by a transfer threshold and characterize the resulting three-phase pattern. Across real-robot manipulation tasks, we observe all three phases: no measurable benefit at low competence ($10.0\\% \\rightarrow 10.0\\%$), a sharp gain after crossing the threshold ($23.3\\% \\rightarrow 86.7\\%$ on flower insertion), and diminishing returns at high competence ($85.0\\% \\rightarrow 93.3\\%$ on pen insertion). We provide a theoretical account based on gradient alignment and residual policy uncertainty, and derive a phase-aware rule for deciding when to collect more new-hardware data and when to reuse legacy demonstrations.

By tuning the laser-energy scale between 1.0 and 3.0, both mechanical stiffness and magnetic response are precisely controlled: the tensile strength increases from 0.28 to 0.99 MPa while maintaining 30-45% elongation at break.

Vector fields (VFs) provide a natural framework by specifying desired motion directions throughout the workspace and enabling direct integration with feedback control. However, most existing VF-based methods cannot explicitly generate trajectories satisfying curvature constraints. Actuator limits are therefore often enforced by input saturation, which may invalidate stability guarantees and degrade closed-loop performance when not considered in controller design. In addition, these methods usually ensure only asymptotic convergence without an explicit settling-time bound. To address these issues, we propose a generalized motion planning and control framework consisting of a finite-time curvature-constrained vector field (FT-C2VF) and a saturation-free control law. Depending on the motion objective, the framework drives the robot to the target configuration in finite time or through it periodically. First, the FT-C2VF is constructed using complementary gains to achieve finite-time convergence while ensuring that the curvature of its integral curves is continuous, bounded, and monotonically decreasing with the radial ratio. Second, an almost globally C1-smooth, saturation-free controller is developed to track the FT-C2VF without Jacobian information, while keeping all control inputs within prescribed actuator limits. Third, dynamical-systems analysis establishes almost-global finite-time stability of the target equilibrium. Numerical simulations show improved performance over representative VF-based methods, and outdoor experiments on an Ackermann-steered vehicle confirm the effectiveness and robustness of the proposed approach.","url":"https://doi.org/10.48550/arxiv.2607.17542","authors":["Xiao, Zhouru","Luo, Sha","Lu, Yang","de Marina, Héctor García","Xu, Zhenyang","Gong, Chaosong","Wang, Yaonan","Yao, Weijia"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2607.17542","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.48550/arxiv.2607.17054","name":"SHAPE: Simultaneous Water Hydraulic Actuation and Position Estimation of a Sensorless Remote Actuator through a Thin and Long Flexible Tube","source":"datacite","abstract":"Robot sensors and electronic equipment are prone to failure in harsh environments.

However, owing to the low impedance and limited camera visibility, accurately positioning the joint (or end effector) to the target location under varying load conditions is challenging. This study proposes a novel method that employs water-filled flexible tubes to enable the transmission of driving power and actuator-side information to and from the actuator, respectively, without actuator-side sensors. By modeling volumetric loss during transmission based on pressure fluctuations and incorporating minor air entrapment, simultaneous power transmission and position estimation is achieved through a tube up to 50 m. Thus, it becomes possible to use a feedback control framework that was previously difficult to implement in sensorless systems.

A central robotics challenge is to coordinate many actuator-sensor modules without assigning a privileged leader, prescribing a fixed gait template, or relying on dense communication. Here we introduce a programmable synchronization-graph framework for modular miniature robots in which each actuator-sensor pair is represented as a network node and locomotor coordination is encoded through graph coupling. Fixed intra-subgraph links synchronize heterogeneous actuator groups, whereas a small number of signed inter-subgraph links program phase relationships between groups. In physical robot collectives with up to nine modules, graph coupling drives the emergence of synchronization, signed links tune the phase difference from in-phase to out-of-phase motion, and floor experiments produce gallop-like and trot-like contact patterns in a five-module robot assembly. Replacing dense all-to-all coupling with sparse d-regular topologies preserves synchronization while reducing the coupling burden. The same graph representation also captures fault tolerance: increasing graph degree increases the number of module deactivations tolerated before desynchronization. Finally, an upper-confidence-bound edge-selection algorithm learns inter-subgraph links that drive the system toward target phase states. In a separate deactivation benchmark, the graph-based controller avoids the leader-specific failure mode observed in centralized leader-follower control and reduces worst-case phase error by about threefold.

This is more than ever true when the latest trends in motion planning are considered. Some motion planners can deal with kinematic and dynamic constraints induced by the mechanical structure of the robot. Another class of motion planners fulfill various types of optimality conditions, yet others include means of dealing with uncertainty about the robot and its environment. Sensor-based motion planners gather information typically afflicted with errors about a partially known environment in order to plan a trajectory therein. In another research area it is investigated how multiple robots best cooperate to solve a common task. In order to deal with the complexity of developing motion planning algorithms, it is proposed in this document to resort to a simulation environment. The advantages of doing so are outlined and a system named Ibex presented which is well suited to support motion planner development. The developed framework makes use of rigid body dynamics algorithms as simulation kernel. Further, various components are included which integrate the simulation into existing engineering environments. Simulation content can be conveniently developed through extensions of well-established 3D modelling tools. The co-simulation with components from other domains of physics is provided by the integration into a leading dynamic modelling environment. Robotic actuator models can be combined with a rigid body dynamics simulation using this mechanism. The same configuration also allows to conveniently develop control algorithms for a rigid body dynamics setup and offers powerful tools for handling and analysing simulation data. The developed simulation framework also offers physics-based models for simulating various sensors, most prominently a model for sensor types based on wave propagation, such as laser range finding devices. Application examples of the simulation framework are presented from the mobile robotics rough-terrain motion planning domain. Three novel rough-terrain planning algorithms are presented which are extensions of known approaches. To quantify the navigational difficulty on rough terrain, a new generic measure named \"obstacleness\" is proposed which forms the basis of the proposed algorithms. The first algorithm is based on Randomised Potential Field Planners (RPP) and consequently is a local algorithm. The second proposed planner extends RRTconnect , a bi-directional Rapidly Exploring Random Tree (RRT) algorithm and biases exploration of the search space towards easily traversable regions. The third planner is an extension of the second approach and uses the same heuristic to grow a series of additional local RRTs. This allows it to plan trajectories through complex distributions of navigational difficulty benefitting from easy regions throughout the motion plan. A complete example is shown in which the proposed algorithms form the basis for sensor-based dynamic re-planning simulated in the presented framework. In the scenario, a simulated planetary rover navigates a long distance over rough terrain while gathering sensor data about the terrain topography. Where obstacles are sensed which interfere with the original motion plan, dynamic re-planning routines are applied to circumnavigate the hindrances. In the course of this document a complete simulation environment is presented by means of a theoretical background and application examples which can significantly support the development of robot motion planning algorithms. The framework is capable of simulating setups which fulfil the requirements posed by stateof-the-art motion planning algorithm development.","url":"https://doi.org/10.5075/epfl-thesis-3663","authors":["Ettlin, Alan"],"tags":["rigid body dynamics","robot motion planning","rough-terrain navigation","sensor simulation","simulation content tool-chain"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2006","doi":"10.5075/epfl-thesis-3663","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.5075/epfl-thesis-7266","name":"Wearable Technologies for Embodied Human-Robot Interaction","source":"datacite","abstract":"Robotic teleoperation is fundamental to augment the resilience, precision, and force of robots with the cognition of the operator. However, current interfaces, such as joysticks and remote controllers, are often complicated to handle since they require cognitive effort and learned skills. Wearable interfaces can enable more natural and intuitive interactions with robots, which would make robotic teleoperation accessible to a larger population of users for demanding tasks, such as manipulation or search-and-rescue. The aim of this thesis is to explore solutions to simplify our interactions with robots promoting their access to a broader range of the population. To achieve this, we are presenting a soft upper body exoskeleton, called the FlyJacket, for the bidirectional control of drones. Drones can greatly benefit us as they extend our perception and range of action. The exoskeleton controls a drone by recording torso movement and, through embedded haptic feedback devices, renders either kinesthetic guidance to improve the flight performance or tactile feedback to render the sensation of flying. We developed and tested an interface to control both a simulated and a real drone. The FlyJacket is a soft exoskeleton with arm support conceived to address the challenges of adapting to different morphologies and supporting the user during flight to prevent fatigue. We demonstrated that this novel interface allowed more consistent performance than when performing the same task with a remote controller and users felt more immersed into the flight. Interacting with a robot can be greatly enhanced by having multiple channels of sensorial feedback to increase the awareness of the operator. Information on the state of the drone can be intuitively rendered with haptic feedback. To create this bidirectional interaction with the drone, the two types of haptic feedback - kinesthetic and tactile - have been explored. Kinesthetic feedback was implemented with a cable-driven system to give guidance to the userâ s torso position. Performing user studies, we could determine that the embedded guidance improved the flight performance and that a quadratically shaped force feedback curve was the most adequate profile to guide the user. We also established the minimal force difference, defined the perceived magnitude of this system and studied the learning process of users. Tactile feedback was investigated to render the sensation of flying by enhancing flight awareness, realism and immersion. To this end, we developed and embedded a new type of soft actuator that was compliant and lightweight such that it remained wearable and portable. Four devices, placed on the torso, provided feedback by compressing closed air pouches against the skin rendering the sensation of air pressure. A mechanical model and simulation of the pouch device were developed to determine appropriate parameters. We evaluated whether it conveyed useful information to the user and whether it enhanced the experience of flying. We demonstrated that users were able to understand the direction of the cues without prompting, could distinguish the cues quickly, and do so with high accuracy. The device was also used in a simulated flight task and users indicated that it increased the flight realism. We believe that the contributions of this thesis provides insights to the design of intuitive interfaces for human-robot interaction and increases their accessibility to a wider range of the population.","url":"https://doi.org/10.5075/epfl-thesis-7266","authors":["Rognon, Carine"],"tags":["Human-Robot Interaction","Telerobotics and Teleoperation","Virtual Reality and Interfaces","Wearable Robots","Wearable Haptics","Kinesthetic Guidance","Tactile Feedback","Soft Robot Applications"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.5075/epfl-thesis-7266","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.26190/unsworks/16708","name":"Cooperative Path Planning for Autonomous Ground Vehicles using 3D Sensor in Cluttered Environment","source":"datacite","abstract":"This thesis is concerned with the real-time path planning of multiple autonomous ground vehicles (AGVs) in a cluttered environment. In order to perform real-time operations with limited processing resources, an efficient path-planning algorithm, identification of the obstacles by a single sensor and cooperative path planning are developed. AGVs are widely utilised for scientific, commercial, industrial and military applications for different tasks such as exploration in hazardous environments and unknown area, military surveillance and reconnaissance, search and rescue missions and industrial automation. For an AGV, path planning in a cluttered environment is a challenging task due to its lack of information about the surroundings and its need to re-plan its path quickly whenever it senses obstacles nearby. Therefore, an efficient path-planning algorithm that offers an AGV sufficient time to re-plan its path to avoid moving obstacles is proposed and, to measure its computational efficacy, its time complexity is considered. Initially, the Efficient D* Lite algorithm, a modified D* Lite graph search algorithm using the Fibonacci heap data structure to speed up the re-planning process in a large dynamic environment, is developed and the Pioneer 3DX (P3DX) mobile robot is used as the AGV platform for experiments. The dynamic equations of motion of robot which rely mainly on physical characteristics, such as the robot and actuator specifications, are derived using Lagrangian formulation to model an actual P3DX robot’s behaviour by taking into account the vehicle’s kinematic and dynamic constraints. This simulated model is used to validate the path-planning algorithm before implementing in real time experiments. In real-time experimentation of autonomous path-planning, AGV relies completely on perception system to sense the immediate environment and avoid obstacles when it traverses towards the goal. As the Time-of-Flight (ToF)-based PMD (Photonic Mixer Device) three dimensional (3D) sensor can provide range and intensity data at low computational cost, it is utilised as a single proprioceptive sensor to detect static and dynamic obstacles. The bistatic model and calibration of the PMD camera system are described to analyse the process of image acquisition. As the future motions of moving obstacles are a priori unknown in dynamic environments, it is essential to estimate them based on observations of the obstacles past and present states so that the AGVs path can be re-planned in advance to avoid collision in critical conditions. An approach which combines the differential scene flow technique and the gradient vector field (GVF) for estimating the kinematic behaviours of the obstacles using the range intensity value of the PMD camera is proposed. To ease the complexity and spatial sparseness in single AGV system in exploring larger area, an effective approach for cooperative multi-AGV system is proposed. As multi-robot systems can be easier, cheaper, more flexible and more fault-tolerant, and cover more space than using one expensive powerful robot, cooperative multi- AGV path planning is addressed. The hybrid and distributed control architecture for a multi-AGV approach is highlighted in which each AGV has its own intelligence to re-plan its path and shares its kinematic and sensor information globally with other AGVs. The PMD camera is mounted on a P3DX and integrated with its software library. The Efficient D* Lite algorithm and scene flow technique are successfully implemented on the P3DX onboard system to carry out real-time autonomous tasks. Finally, real-time experiments are performed with three AGVs in different scenarios in order to demonstrate all the path-planning features and validate the proposed approaches. Videos of the experiment are presented in a CD-ROM (Appendix D).","url":"https://doi.org/10.26190/unsworks/16708","authors":["Francis, Sobers"],"tags":["PMD camera","Cooperative path planning","autonomous vehicles","Pioneer3DX mobile robot"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2013","doi":"10.26190/unsworks/16708","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.24433/co.7739053.v1","name":"Hexapod Research – Web-Based Joint-Level Control Bridge for a Dynamixel Hexapod","source":"datacite","abstract":"This capsule contains the software implementation and reproducibility workflow for a Python-based joint-level control bridge for a Dynamixel-based hexapod robot.

Machine learning has been employed to acquire such behaviours, usually by trial-and-error learning. A succession of trials is performed that initially fail frequently. As more experience is gained, the actions that govern the robot’s performance are progressively refined until the robot reliably executes its assigned task. However, this process often requires a large number of iterations. If an online learning process must be performed, that is, learning on board the robot as it operates, simplistic approaches to trial-and-error learning are infeasible. The robot will break down long before any significant progress is made. Solutions to this problem include combinations of model-based reinforcement learning, planning, and behavioural cloning, all of which attempt to narrow the search space of trial-and-error learning. However, these approaches rely on a significant amount of domain knowledge specific to the robot and task, and cannot be adapted to other robots or tasks. This thesis proposes a Planning and Learning Hierarchy~(P/LH) that improves the feasibility and efficiency of online skill acquisition, through a domain independent approach. A qualitative model of the robot is built from behavioural traces that are collected as the robot operates. The model trades accuracy for domain independence in elevating the skill acquisition problem into the high-level symbolic realm. A forward-chaining planner subsequently finds a sequence of actions that the robot must perform to carry out its assigned task. A second stage of learning is then employed to refine the plan. This is guided by the plan, which significantly constrains the parameters governing the robot's actuator movements. This narrows the search space of low-level reinforcement learning that discovers satisficing or optimal values for the parameters. The P/LH is applied to locomotion tasks on a multi-tracked robot typical of those designed for urban search and rescue. Rescue robots are prone to slipping, and typically have noisy sensors and inaccurate actuators, as weight restrictions limit the robot's physical and computational power. Therefore, this domain is an ideal application of online algorithms that learn new behaviours.

These robots face various control challenges like high dimensionality, contact switches during locomotion and a floating-base nature which makes them fall all the time. A rich set of sensory inputs and a high-bandwidth actuation are often needed to ensure fast and effective reactions to unforeseen conditions, e.g., terrain variations, external pushes, slippages, unknown payloads, etc. State of the art technologies today seem to provide such valuable hardware components. However, regarding software, there is plenty of room for improvement. Locomotion planning and control problems are often treated separately in conventional humanoid control algorithms. The control challenges mentioned above are probably the main reason for such separation. Here, planning refers to the process of finding consistent open-loop trajectories, which may take arbitrarily long computations off-line. Control, on the other hand, should be done very fast online to ensure stability. In this thesis, we want to link planning and control problems again and enable for online trajectory modification in a meaningful way. First, we propose a new way of describing robot geometries like molecules which breaks the complexity of conventional models. We use this technique and derive a planning algorithm that is fast enough to be used online for multi-contact motion planning. Similarly, we derive 3LP, a simplified linear three-mass model for bipedal walking, which offers orders of magnitude faster computations than full mechanical models. Next, we focus more on walking and use the 3LP model to formulate online control algorithms based on the foot-stepping strategy. The method is based on model predictive control, however, we also propose a faster controller with time-projection that demonstrates a close performance without numerical optimizations. We also deploy an efficient implementation of inverse dynamics together with advanced sensor fusion and actuator control algorithms to ensure a precise and compliant tracking of the simplified 3LP trajectories. Extensive simulations and hardware experiments on COMAN robot demonstrate effectiveness and strengths of our method. This thesis goes beyond humanoid walking applications. We further use the developed modeling tools to analyze and understand principles of human locomotion. Our 3LP model can describe the exchange of energy between human limbs in walking to some extent. We use this property to propose a metabolic-cost model of human walking which successfully describes trends in various conditions. The intrinsic power of the 3LP model to generate walking gaits in all these conditions makes it a handy solution for walking control and gait analysis, despite being yet a simplified model. To fill the reality gap, finally, we propose a kinematic conversion method that takes 3LP trajectories as input and generates more human-like postures. Using this method, the 3LP model, and the time-projecting controller, we introduce a graphical user interface in the end to simulate periodic and transient human-like walking conditions. We hope to use this combination in future to produce faster and more human-like walking gaits, possibly with more capable humanoid robots.","url":"https://doi.org/10.5075/epfl-thesis-8760","authors":["Faraji, Salman"],"tags":["Mechanics","Control","Optimization","Bipedal Walking","Planning","Compliance"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.5075/epfl-thesis-8760","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.26190/unsworks/3306","name":"A Novel Switched Reluctance Motor for Industrial and Commercial Applications","source":"datacite","abstract":"Switched reluctance motors offer many benefits such as simplicity of construction, low costs, fault-tolerance and a high torque to inertia ratio. They also have no reliance on rare earth metals and therefore have no demagnetisation temperature limitation. These benefits have made switched reluctance motors an attractive contender for use in a plethora of applications. These benefits however have been hindered by problems such as noise, torque ripple and lower torque density. It is only in recent times that reluctance machines can begin to compete with existing motor technologies through the use of new machine topologies. With advanced machine design and the holistic development of power electronics and microprocessor control methods, the advantages of these motors are brought to the fore. In recent years, field oriented control has been implemented on stepper motor drives in order to achieve servo-like performance. This performance can be achieved at a fraction of the cost of a traditional permanent magnet synchronous servo system. While this is suitable for small size motors, larger size stepper motors with a high output power, large speed range and low cogging torque do not exist. A class of motors with these characteristics is needed to provide a low cost alternative to costly torque motors and to allow machine designers to reap the benefits of direct drive systems. Direct drive motors offer many advantages and allow a gearbox or other speed reduction measures to be eliminated. Such advantages include the lowering of the system cost, design simplification, higher reliability and lower maintenance. In the development of the novel reluctance machine, techniques to alleviate these problems have been developed with minimal compromise of the machine performance while minimising the cost of the motor. An ideal application for the motor design, and one of the case studies in this thesis, is its use as the principle actuator for a delta robot lever arm.

When physical mobility is compromised, whether due to natural aging, disease, or injury, quality of life tends to decline substantially. Assistive technologies aim to counteract these limitations by providing functional compensation, training, or rehabilitation. In particular, wearable robotic assistive devices such as actuated exoskeletons and prostheses promise active support tailored to individual needs. In order to facilitate intuitive operation for the human user, the assistive device must recognize the current need for support and adapt its response accordingly. However, this seamless integration of assistive devices with their human users remains an open challenge. Typically, technical aspects and human factors tend to be considered separately, despite the fact that these assistance scenarios constitute a complex form of human-robot interaction, characterized by mutual influence and interdependent dynamics. Early involvement of users in the technical development through human-in-the-loop experiments promises a holistic view of the interaction. In addition, a seamless integration requires bidirectional exchange of information, which necessitates sensory and feedback interfaces. Human motion sensing provides valuable information for the development, control, and evaluation of assistive devices, while haptic feedback offers an intuitive channel for conveying information to the user. This thesis addresses these key elements of the human-robot interaction loop in the context of wearable systems and technology for mobility assistance. Human motion sensing is explored in terms of kinematic data acquisition and muscle activity monitoring, which are considered complementary sources of information, with a focus on wearable solutions. A modular motion capture system based on inertial measurement units (IMUs) is designed as a versatile tool for the acquisition of kinematic data in movement analysis, human-machine interaction, and wearable robotics. In order to extract meaningful biomechanical information from the IMU data, a system calibration establishes transformations between the wearable sensor modules and the body segments. An automatic sensor-to-segment alignment approach is employed to enable self-calibration based on arbitrary movements. The approach is evaluated in both a simulation and a gait experiment involving a human participant. The simulation results demonstrate the alignment approach's robustness to varying initialization values and noisy motion data. The joint angle trajectories obtained from the gait experiment are consistent with expected kinematic patterns during walking. Compared to a state-of-the-art sensor-to-segment alignment procedure, the joint angle results exhibit root mean square errors ranging from 2.1 to 7.2°, while Pearson correlation coefficients are larger than 0.91 for all joints. For the acquisition of muscle activity information, the emerging transducer technology of flexible ferroelectrets is explored as a more robust alternative or supplement to conventional electromyography (EMG). Ferroelectret-based force myography (FMG) and EMG are compared in a gait experiment, acquiring data from two thigh muscles. The resulting FMG signal patterns resemble the muscle activity captured by EMG, with mean absolute errors of 6.1 % for the vastus medialis and 18.9 % for the biceps femoris. In particular, the FMG signals are more consistent across strides, exhibiting less than half the stride-to-stride variability. Haptic feedback is examined as an information channel, focusing on the vibrotactile modality, which allows for compact and unobtrusive wearable designs.

While conventional approaches attempt to bridge this gap by increasing simulator fidelity through system identification, domain randomization, or learned actuator models, we introduce an alternative paradigm: actuator reality shaping. Instead of modifying the simulator to match the real world, our method shapes the closed-loop behavior of physical actuators to match the idealized second-order reference dynamics used in simulation. By equipping each joint with a two-degree-of-freedom feedforward--feedback controller, we decouple reference-response shaping from robust stabilization, thereby providing a standardized actuator interface for reinforcement learning policies. As a result, policies trained only with the prescribed reference model can be deployed zero-shot on real hardware without task-level fine-tuning or learned actuator models. We validate the approach on a single-joint high-gear-ratio servo under external loads and a 7-DOF robotic arm reaching task, where actuator reality shaping substantially reduces sim-to-real tracking error and improves zero-shot task performance compared with standard servo-control and representative real-to-sim-to-real baselines. We further demonstrate zero-shot transfer on a wheeled-legged robot driving over a slope and a humanoid robot walking, suggesting that actuator reality shaping can serve as a reusable interface for robot learning across diverse hardware platforms.

Rather than estimating external wrenches or commanding torque, our method predicts a compliance reference position: an ideal joint-position target for a standard PD controller whose induced position error generates appropriate grasping force. This position-based formulation is compatible with mainstream teleoperation and policy-learning pipelines, while enabling the robot to adapt interaction forces from real-time proprioceptive feedback. Thus, motor current serves not only as a force proxy but also as a learnable proprioceptive contact signal for compliance reference prediction. Experiments on multiple dexterous hands and contact-rich tasks, including fragile object handling, sustained surface contact, thin-object retrieval, and dynamic load adaptation, show stable compliant grasping, safer and more efficient teleoperation, and improved downstream policy learning without external tactile or force sensors.","url":"https://doi.org/10.48550/arxiv.2607.03529","authors":["Ma, Chenyang","Yao, Yunchao","Wei, Zhenyu","Li, Ruogu","Szafir, Daniel","Ding, Mingyu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2607.03529","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.82465/6020","name":"Collision Free and Energitaclly Optimized Motion Planning of Manipulators in Partially-Known Environment Using Modified D* Life Algorithm","source":"datacite","abstract":"Robotics is a relatively young field of studies in modern technology and it has tremendously grown during the past fifty years. Manipulators are categorized as a group of robots designed to accomplish the manipulation tasks without direct contact by a human. Generating an optimized algorithm to transform high-level motion tasks to low-level description that are understandable by the robots, including manipulators, has been one of the most interesting problems in this field. Motion planning in robotics, is referred to the process of breaking down a desired movement task into discrete motions in order to satisfy some specific criteria and optimize some certain variables during the motion from the start point to the goal point. Although various types of problems in robot motion planning have been investigated; trajectory planning for the manipulators in partially-known environment with respect to the amount of energy consumption has not been fully addressed. This aspect of motion planning can be of great importance in optimizing the path planner algorithms while satisfying their collision free attribute. This study attempts to develop a comprehensive mathematical model for robot-actuator system dynamics to include the energy consumption level as a variable in the cost function of the path planner algorithm. For this purpose, the manipulator’s general equation of motion is derived using the Lagrange equations. Same approach has been taken to develop the equation of motion of the robot’s actuators which are considered to be DC motors at each joint of the manipulator. The fourth order of Runge-Kutta algorithm is used to solve the coupled governing differential equations of the system. The output of the modeling phase of the study is fed to the graph search algorithm as an input. Graph search algorithm deals with the start-to-goal node problem in which the best path in a network of nodes is desired. D* Lite algorithm is one the most well-known algorithms in dealing efficiently with the partially-known environment motion planning problems. The advantages of D* Lite algorithm over the other famous algorithms such as A* are investigated, the best path generation procedure is thoroughly discussed, and the implementation of the algorithm is deliberated. A modification on D* Lite algorithm is proposed here to enhance the efficiency of the best path generation method and the alternative procedure is provided correspondingly. A MATLAB framework is designed to define the robot and its workspace and the manipulator equation of motion is developed using MATLAB classes to transform the user input values into the state space variables of the system. Several scenarios have been simulated using the developed framework to verify the path planner effectiveness in avoiding the pre-known and partially-known obstacles while minimizing the amount of consumed energy by the manipulator during its motion from the start node to the goal node.","url":"https://doi.org/10.82465/6020","authors":["Feizollahi, Amir"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2016","doi":"10.82465/6020","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.48550/arxiv.2603.22055","name":"MineRobot: An Actuator-Centered Kinematic Modeling and Solving Framework for Underground Mining Robots","source":"datacite","abstract":"Underground mining robots are increasingly modeled for planning, operator training, and digital-twin workflows, where reliable actuator-level kinematics is needed to reduce hazardous in situ trials.

Underactuated mechanisms are advantageous in aquatic environments because reducing actuator count lowers motor-leakage risk while introducing inherent mechanical compliance. However, accurate modeling of underwater underactuated and soft robotic systems remains challenging, as it requires identifying high-dimensional structural and hydrodynamic parameters. In this work, we propose a trajectory-driven global optimization framework for unified structural-hydrodynamic modeling of underwater multibody systems. Inspired by the Covariance Matrix Adaptation Evolution Strategy (CMA-ES), the proposed approach simultaneously identifies coupled elastic, damping, and distributed hydrodynamic parameters through trajectory-level matching between simulated and experimental motion. This enables high-fidelity reproduction of underactuated mechanisms and compliant soft robotic systems in underwater environments, using as little as a single video recording. We first validate the framework on a link-by-link underactuated multibody mechanism, demonstrating accurate identification of distributed hydrodynamic coefficients, with normalized end-effector position error below 5% across multiple trajectories, initial conditions, and both active-passive and fully passive configurations. The modeling strategy is further validated on an asymmetric octopus-inspired soft arm, confirming its effectiveness for compliant soft robotic systems. Finally, eight identified arms are assembled into a swimming octopus robot, where the unified parameter set enables realistic whole-body behavior without additional retuning. These results demonstrate the scalability and transferability of the proposed structural-hydrodynamic modeling framework across underwater underactuated and soft robotic systems.","url":"https://doi.org/10.48550/arxiv.2603.07939","authors":["Zhang, Chenrui","Zhang, Yiyuan","Ye, Yunfei","Chen, Junkai","Wang, Haozhe","Laschi, Cecilia"],"tags":["Robotics (cs.RO)","Fluid Dynamics (physics.flu-dyn)","FOS: Computer and information sciences","FOS: Physical sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2603.07939","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:16.227Z"},{"id":"doi:10.5281/zenodo.20939688","name":"The Contact Layer: Why Robotics' Next Frontier Is Physics, Not Just Intelligence","source":"datacite","abstract":"The dominant robotics narrative of the past several years has treated capable robots as primarily an intelligence problem: better perception, better planning, larger vision-language-action models, and broader demonstration datasets.

Many researchers have drawn inspiration from animal movement modes as they are uniquely adapted to movement through such environments. Snakes are able to navigate a wide variety of unpredictable and rough terrain with ease, utilising different gait styles to adapt to the environment around them. Snake body morphology lends well to robotic adaptation, making them a good foundation for bio-inspired robots. These robots have potential applications in navigating unpredictable environments, such as for Search-And-Rescue (SAR), or for traversing through small passages. In order to provide compliance to the joints, series elastic actuators (SEA) are commonly found in snake robots. These provide shock tolerance to the joint and assist with filtering high frequency noise. A novel SEA was developed for the snake robot presented in this thesis; different designs were tested and evaluated to produce a SEA with the desired non-linear torque-deflection profile. Different materials were evaluated against each other to assess the effect of material properties on the response profile, which found that 5 [mm] thick polyurethane Shore 95A (PU-95A) resulted in the most compliant SEA. The elastic element was manufactured using low-cost materials and methods where possible, to produce an accessible design without compromising on torsional sensing resolution. This thesis presents an Accessible Snake Platform with Elastic Nonlinearity (ASPEN), comprised of eleven body modules manufactured from stereolithography (SLA) printed resin, and one head module; assembled in the three-dimensional (3-D) configuration, where sequential modules are rotated 90°. Each module consists of a custom printed circuit board (PCB) assembly, battery, actuator, servo motor, and the segment shell itself. The joint control is provided by an STM32 microcontroller unit (MCU) on the PCB assembly, which uses flexible data rate controller area network (FDCAN) to communicate between segments and relay sensor data back to the head module. The head module contains a Raspberry Pi 4b, which acts as the gait pattern generator (GPG), and communicates desired joint angles to the head module PCB to relay to other segments through FDCAN. A depth-sensing camera is installed in the head module, in order to provide depth data which can be processed using OpenCV libraries and used for object-based motion. The system calculates desired joint angles based on propagating waves through the lateral and dorsal joints of the robot. ASPEN is equipped with the ability to generate the rolling, sidewinding, and lateral undulation gaits. These gaits were implemented successfully in simulation, where ASPEN performs rolling at 0.042 [m/s], sidewinding at 0.1 [m/s], and lateral undulation at 0.125 [m/s]. A head stabilisation method for lateral undulation was implemented to improve the image quality of the camera footage. This was shown to decrease the head angle swing range by 56%, and the head angle y-displacement by 50%. However, this also resulted in a reduction of robot speed by 50% in simulated results. Adaptive gait modulation was implemented in order to begin shifting towards an adaptive control system. Both the adaptive lateral undulation and adaptive sidewinding gaits demonstrated the ability for gait modulation to change the MGP of the snake, resulting in a curved motion path. Simulated results also demonstrated the ability to use the lateral undulation gait for object avoidance; this had the consequence of a 50% reduction in speed. Snakes that move with different gaits possess different frictional properties of their ventral scales. Inspiration was taken from this feature to develop “ventral panels” which slot into the outer sides of the body segments and are used to create frictional anisotropy.

In this paper, we propose a robust, membrane-based acoustic microrobot that overcomes these limitations by employing a thin flexible Polydimethylsiloxane (PDMS) membrane bonded over confined microcavities for microstreaming. The introduced design physically prevents gas diffusion, ensuring stable performance over extended periods at high actuation voltages.

This letter presents a physics-based, linear-in-parameters model for the electrical power consumption of the seven-degree-of-freedom left arm of the Unitree~G1 humanoid robot. The proposed formulation combines actuator loss terms with a baseline-torque correction that captures changes in gravity-compensation load and enables accurate prediction of negative net power trajectories. Pairwise interaction terms are introduced to model power coupling during simultaneous multi-joint motion. Model parameters are identified from experimental data collected on a physical Unitree~G1 using onboard power measurements as the regression target. Across 897 trajectories covering single-joint and coordinated arm motions at multiple speed levels, the identified model achieves $R^2 = 0.933$ with an RMSE of 1.07 (W). Validation on 46 trajectories executed at previously unseen speeds yields $R^2 = 0.965$, demonstrating strong generalisation beyond the identification dataset. Analysis of the identified parameters reveals distinct power-consumption characteristics across the arm, with viscous friction dominating most joints (shoulder pitch and all three wrist joints), copper losses dominating shoulder yaw and the elbow, and shoulder roll uniquely dominated by Coulomb friction.","url":"https://doi.org/10.48550/arxiv.2606.15915","authors":["Deniz, Nestor N.","Vega, Sebastian","Parsons, Simon","Cheein, Fernando Auat"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.15915","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.82589/muir-501","name":"POSITION AND ORIENTATION CONTROL OF A 6-DOF ROBOT USING FEEDFORWARD ANFIS-PID CONTROLLER","source":"datacite","abstract":"Robotic systems with six degrees of freedom (6-DOF) have become essential in high-precision tasks such as industrial welding and surgical operations. These systems necessitate sophisticated control strategies to address the complexities of nonlinear dynamics, actuator behaviors, and external disturbances. In this research, a feedforward Adaptive Neuro-Fuzzy Inference System (ANFIS)-PID controller was developed for the precise position and orientation control of a 6-DOF robotic manipulator. The kinematic model of the robot was formulated using the DenavitHartenberg (DH) convention, allowing for the derivation of forward and inverse kinematics. The accuracy of the kinematic model was verified through simulations conducted in MATLAB. A dynamic model, which integrated actuator dynamics for all six joints, was developed using MSC Adams and validated in a co-simulation environment. This high-fidelity model enabled the realistic simulation of the robot’s mechanical and dynamic behavior. The ANFIS-PID controller was designed and tested within a MATLAB/Simulink co-simulation environment, which interfaced seamlessly with the dynamic model from MSC Adams. The performance of the developed controller was evaluated in terms of trajectory tracking and disturbance rejection. Results indicated that the controller significantly outperformed traditional PID controllers, achieving position errors below 0.3° under normal and disturbed conditions. These findings highlighted the ANFIS-PID controller’s adaptability to nonlinear dynamics and superior performance in comparison to its conventional counterparts. Despite its successes, limitations were identified. Factors such as link elasticity and joint friction were not incorporated into the dynamic model, and the training of the ANFIS model was constrained by computational resources. These omissions have been recommended for future research to enhance the model’s accuracy and real-world applicability. Nevertheless, the objectives of this research were achieved, and the potential of hybrid controllers in addressing the challenges of robotic control systems was demonstrated.","url":"https://doi.org/10.82589/muir-501","authors":["Gebrekiros Haile"],"tags":["6-DOF robot","kinematic modeling","dynamic modeling","ANFIS-PID controller."],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.82589/muir-501","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.48550/arxiv.2606.12728","name":"EquiDexFlow: Contact-Grounded SE(3)-Equivariant Dexterous Grasp Generative Flows","source":"datacite","abstract":"Most learned dexterous grasp generators relegate contact forces to a downstream verification step, so a kinematically-plausible pose can still violate the conditions for a stable physical grasp.

Local learning provides a potential path toward energy-aware on-robot adaptation by replacing global backpropagation graphs with updates driven by local neural states, making the learning rule more compatible with neuromorphic and in-memory computing substrates. This work proposes an equilibrium-propagation (EP)-based proximal policy optimization (PPO) framework for uneven-terrain quadruped locomotion. The controller combines a bio-inspired central pattern generator (CPG) policy with a residual postural adjustment policy, while replacing conventional backpropagation-trained policy and value networks with EP-enabled local learning. To train stochastic continuous-control policies with EP, we derive an EP-compatible PPO output-nudging signal and introduce a two-sided ratio clipping mechanism that stabilizes policy updates during relaxation. Experiments on a 12-DoF A1 quadruped show that the proposed controller achieves stable policy convergence in a two-stage uneven terrain locomotion task. Its locomotion performance is comparable to a backpropagation-trained PPO baseline in success rate, velocity tracking, actuator power, and body stability, while improving GPU memory efficiency by 4.3\\(\\times\\) compared with backpropagation through time (BPTT).

Real robots can experience joint-level changes caused by actuator degradation, hardware faults, safety limits, collision damage, or wear-induced friction. These faults are critical because they alter the action-to-motion interface of a policy, disrupting the learned closed-loop relationship between commanded actions, realized motion, and subsequent observations. In this work, we study realistic joint-level physical faults and show that VLA models are vulnerable when predicted actions are executed through a perturbed robot body. Our analysis reveals joint-dependent effects, with heterogeneous degradation in task success across affected joints. We also show that performance drops cannot be attributed solely to physical infeasibility, since feasible faults such as increased joint friction can still substantially reduce success rates and induce closed-loop execution mismatch. Motivated by these findings, we propose Joint-level Physical-fault Aware Residual Calibrator (J-PARC), a lightweight residual calibration framework built on top of a frozen VLA policy. J-PARC infers a latent joint-fault regime from recent joint dynamics and conditions a shared residual calibrator on this regime, enabling adaptive action correction across faulty joints.

Existing approaches often tackle visual or dynamic gaps separately, overlooking how these individual mismatches accumulate and propagate throughout the robot's state evolution. In this paper, we introduce QuadVerse, an integrated framework that uses reconstructed scenes as a calibration substrate for aligning visual perception, physical interaction, and actuator dynamics. From captured RGB videos, we reconstruct geometry-constrained 3D Gaussian Splatting (3DGS) scenes that support batched photorealistic ego-view rendering and collision-ready semantic mesh extraction. The meshes further enable contact calibration by initializing spatially varying friction priors and refining them through trajectory-based posterior search. To address remaining actuator discrepancies, QuadVerse trains a residual dynamics compensator by replaying real-world trajectories on the contact-calibrated terrain, reducing the entanglement between terrain-induced contact errors and actuator non-idealities. Experiments show that QuadVerse improves reconstruction quality and locomotion tracking over relevant baselines.

The desired competing performance requirements as well as constraints from the physical system can be characterized with weighting functions for respective signals. Considering the frequency properties of human movements, the passivity constraint for stable human-robot interaction, which is required on the entire frequency spectrum and may bring conservative solutions, has been relaxed in such a way that it only restrains the low frequency band. Thus, impedance control became a mixed $H_2/H_\\infty$ synthesis problem, and a dynamic output feedback controller can be obtained.

Slow-rate sensing enables to achieve energy saving by reducing network load. In addition, choosing a slower sensing period than the longest round-trip time delay can avoid packet disorder. On the other hand, a slow-rate sensing usually degrades control performance in a conventional control framework. Therefore, including dual-rate control techniques can be useful to maintain the desired performance, since the controller is able to generate a fast-rate control signal from a slow-rate sensing signal. A dual-rate PID controller is used, which can be split into two parts: a slow-rate PI controller is located at the remote side (with no permanent communication to the plant) and a fast-rate PD controller, at the local side (close to the plant, sensor, and inside the actuator, which can offer a low computation power). In addition, at the remote side, where a powerful computation device is located, a prediction stage is included in order to generate the packet of future, estimated slow-rate control actions to be sent to the local side. At this side, these actions are converted to fast-rate ones and used when a packet does not arrive due to the network-induced delay or due to occurring dropouts.

The ability to perform, in a provably correct manner, such a complex task at the servo level can lead to a large increase in the speed of operation, low energy consumption and high quality of response. Planning has been traditionally limited to the high level controller of a robot. The guidance velocity signal from this stage is usually converted to a control signal using what is known as an electronic speed controller (ESC). This paper demonstrates the ability of the harmonic potential field (HPF) approach to generate a provably correct, constrained, well behaved trajectory and control signal for a rigid, nonholonomic robot in a stationary, cluttered environment. It is shown that the HPF based, servo level planner can address a large number of challenges facing planning in a realistic situation. The suggested approach migrates the rich and provably correct properties of the solution trajectories from an HPF planner to those of the robot. This is achieved using a synchronizing control signal whose aim is to align the velocity of the robot in its local coordinates, with that of the gradient of the HPF. The link between the two is made possible by representing the robot using what the paper terms separable form. The context-sensitive and goal-oriented control signal used to steer the robot is demonstrated to be well behaved and robust in the presence of actuator noise, saturation and uncertainty in the parameters.

To the best of our knowledge, this result constitutes the first successful sim-to-real transfer for a four-degrees-of-freedom muscle-actuated robot arm.","url":"https://doi.org/10.48550/arxiv.2604.09487","authors":["Schneider, Jan","Mahajan, Mridul","Chen, Le","Guist, Simon","Schölkopf, Bernhard","Posner, Ingmar","Büchler, Dieter"],"tags":["Robotics (cs.RO)","Machine Learning (cs.LG)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2604.09487","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.48550/arxiv.2606.00197","name":"Cuttlebot: a platform demonstration for complex, autonomous, bio-inspired swimmers","source":"datacite","abstract":"Increasing interest in deep-sea operations and resources motivates the development of ecologically sensitive but environmentally durable robots.

The proposed method formulates a convex quadratic programming problem whose decision variable is the joint-level required velocity. Control barrier function style bounds impose reference-level joint-limit admissibility, while the task equation is handled through a penalized slack variable. Redundancy is resolved using a controller-compatibility objective that accounts for previous-command consistency and actuator torque-capacity weighting. The method is independent of the particular torque-level controller and can serve as an intermediate IK layer between an endpoint trajectory and a redundant robot controller.

Some birds, such as kestrels, are capable of remarkably steady flight under these same conditions. The mechanisms birds use to achieve this steadiness remain poorly understood. Studying birds’ gust-mitigation strategies may inspire novel control mechanisms that enhance the stability of Small Uncrewed Aerial Vehicles (SUAVs). To that end, this thesis aims to identify the wing and tail kinematics used by two gliding Nankeen kestrels (Falco cenchroides) to maintain steady flight during gust encounters. A wind-tunnel gust generator was developed to produce vertical (upward and downward) and rolling gusts, allowing controlled perturbations of soaring birds. The generator, located downstream of the birds, used deflecting louvres to modify the strength of the updraft in which the birds hovered. The gusts were highly repeatable and produced effective angle-of-attack changes of up to 20 deg within 0.2 s, approximating the magnitudes and periods of gusts measured in nature. Compared to outdoor flight tests, the wind tunnel offered the advantage of carefully controlled and measurable flow characteristics, while the gust generator enabled the creation of a wide range of discrete and repeatable gust profiles. Two kestrels were trained to hover above the gust generator. The presence of an updraft allowed them to maintain a stationary hover without flapping. The birds were then subjected to known, controlled gusts, and their kinematic responses were tracked using motion-capture cameras. A total of 468 gust encounters were recorded, and ensemble averages revealed clear trends in the birds’ responses to vertical gusts. The kestrels decreased the pitch angles and the areas of their wings and tail in response to upward gusts and did the opposite for downward gusts. Wings were elevated in response to upward gusts, while downward gusts prompted flapping. Wing and tail deflections occurred in the same direction as the gust loads. The very short response latency estimates (&lt;30 ms) for elevation and pitching motions suggest that these responses were passively initiated. Additionally, the birds typically flew at high angles of attack (15–30 deg), likely placing them within the soft-stall lift plateau where lift fluctuations are dampened by a shallow lift-curve slope.The inertial and aerodynamic loads associated with the kestrels’ gust responses were also estimated. The mass distribution of a kestrel was obtained from a Computed Tomography (CT) scan of a cadaver. The mass and acceleration of the wings were found to produce negligible inertial forces compared to gust loads. A robotic morphing kestrel wing and tail (developed externally to this thesis) was used to replicate the birds’ wing extension, tail spread, and tail pitch responses. These degrees of freedom were sufficient to balance pitching moments during gust encounters, though not lift and drag. The effects of wing elevation and pitching were not captured by the robot, as it did not possess those degrees of freedom. These findings highlight several gust-mitigation strategies that may inform the design of steadier SUAVs. Designing SUAVs with soft stall characteristics and flying at high angles of attack would reduce lift fluctuations. Flight surfaces may be designed to exhibit passive aeroelastic deflections under gust loads that stabilise flight. Additionally, control surfaces that actuate with gust loads may reduce actuator loads and latencies.","url":"https://doi.org/10.25439/rmt.32443113","authors":["Penn, Matthew"],"tags":["Aircraft performance and flight control systems","Flight dynamics","Animal behaviour"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.25439/rmt.32443113","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.48550/arxiv.2605.26936","name":"A Bioinspired Underwater Robot with a Latch-Mediated Soft Bistable Mechanism","source":"datacite","abstract":"Underwater robotics has advanced significantly over recent decades. however, the development of miniaturized underwater robots remains limited by low energy densities of traditional power sources.

Previously, a velocity-level closed loop inverse kinematics controller had been developed and tested in simulation on a detailed physics-based model of the MHT in LMS Virtual.Lab Motion (VLM). The controller was employed to generate a variety of posture reconfiguration and navigation maneuvers in simulation, such as achieving minimum or maximum chassis height at specific wheel separations, orienting the chassis to a desired pitch angle, or negotiating simulated rough terrain. In this thesis, the aforementioned inverse kinematics controller was improved upon, optimized and adapted to function on the physical MHT vehicle, located in Suffield, Canada. In addition, as a first step towards identifying the deficiencies of the VLM model and, ultimately, validating the model, actuator performance was measured for open loop step and ramp inputs and compared to the simulation results. With the controller implemented on MHT, a subset of the posture reconfiguration and navigation maneuvers previously performed in simulation were tested on the MHT and the robot performance was evaluated.

Under this framework, robotic systems increasingly resemble managed infrastructure platforms analogous to enterprise SaaS, leased industrial equipment, cloud computing services, and fleet vehicle ecosystems.

Volume II extends the analysis into the 2031–2041 horizon, examining the transition from deployment-heavy robotics ecosystems toward embedded autonomous infrastructure.

Incorporating the conductive polymer PEDOT:PSS adds real‑time force sensing for precise control and adaptability in artificial muscle applications.Third, we develop a bio‑inspired insole that delivers phase‑appropriate, tunable stiffness by integrating STG into a hyperelastic Dragon Skin 30 backbone. Because aging and deformities impair intrinsic muscle activity and the plantar fascia windlass, foot stiffness modulation degrades, plantar pressure distribution shifts, and stability and propulsion suffer. In a case study involving an older adult with sarcopenia, pes cavus, and hindfoot varus, custom bio‑insoles with regionally tuned stiffness augmented medial forefoot and arch support while stabilizing the lateral hindfoot. The insoles improved rearfoot and medial‑column engagement, enhanced propulsive mechanics, and reduced neuromuscular demand.Overall, by leveraging the merits of shear-thickening materials, we have successfully developed mechanically compatible and rapidly responsive wearable assistive devices, thereby broadening the material and design space for a wide range of applications.","url":"https://doi.org/10.25442/hku.32153655","authors":["Zhang, Qingqing","Xi, Ning"],"tags":["Assistive robots and technology","Biomechatronics","Control engineering, mechatronics and robotics not elsewhere classified"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.25442/hku.32153655","addedAt":"2026-08-31T06:34:12.477Z","updatedAt":"2026-08-31T06:34:12.477Z"},{"id":"doi:10.5281/zenodo.20325614","name":"HASEL-Based Metabolic Soft Robotics: A Framework for PET-Assimilating Self-Maintaining Artificial Muscle Bodies","source":"datacite","abstract":"This paper proposes HASEL-Based Metabolic Soft Robotics, a framework for designing soft robotic bodies that preserve external morphology while renewing internal material components through partial robotic metabolism.

This work introduces a novel in-plane DEA-based thin soft-rigid hybrid robot for fast movement. The innovative design features a multi-layer silicone-based elastomer tensioned by an in-plane elastic PETG frame. A detailed spin coating fabrication method is presented for producing multilayer silicone-based in-plane DEAs. The robot demonstrated effective crawling on flat surfaces and resonance-driven high-speed locomotion at 53 Hz, achieving a peak velocity of approximately 12.3 mm s −1 which is 34.2% of its body length per second and 224% of body thickness per second. This study highlights the potential of DEAs for advancing miniaturised soft robotics, especially in applications that demand lightweight, flexible, and thin profile actuators.","url":"https://doi.org/10.1088/1361-665x/add067","authors":["Xi Wang","Jung-che Chang","Siqian Li","Cheng He","Feiran Wang","Dragos Axinte","Xin Dong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-04-24T22:55:55Z","doi":"10.1088/1361-665x/add067","addedAt":"2026-08-31T06:34:12.794Z","updatedAt":"2026-08-31T06:34:12.794Z"},{"id":"doi:10.52843/cassyni.2jdmwx","name":"Simplification method for the dynamic model of the giant magnetostrictive actuator","source":"crossref","abstract":"To simplify the model of a giant magnetostrictive actuator, we propose the approach of employing the basic magnetization instead of the loop, and considering the hysteresis loss by compensating the mechanical damping.

The proposed control framework combines a Proportional-Integral-Derivative (PID) controller with null-space projection to exploit the platform’s inherent redundancy for secondary objectives, such as singularity avoidance, energy optimization, and enhanced fault tolerance. A clamping strategy ensures that actuator lengths remain within operational limits, thereby preventing mechanical failures. Simulation results demonstrate significant error reduction in both position and orientation, even under strict actuator constraints. Specifically, the system achieved exponential convergence to the desired pose within 3 s, with a maximum position error of less than 1 × 10−3 m and orientation error below 5 × 10−4 rad. Actuator efficiency was also enhanced, as the algorithm dynamically redistributed efforts among actuators to avoid overloading any single leg. While energy consumption was not explicitly optimized in this study, the framework provides a foundation for future work in minimizing energy usage through advanced secondary objectives. Stability is analyzed rigorously using Lyapunov’s direct method. Compared to traditional six-legged platforms, the 8- legged design offers superior flexibility and adaptability, making it particularly suitable for applications in flight simulators, robotic surgery, and industrial automation where precision and reliability are critical. However, the proposed approach has certain limitations. For instance, the current implementation assumes ideal actuator dynamics and does not account for uncertainties such as friction, backlash, or external disturbances. Additionally, the clamping strategy may introduce computational overhead, potentially impacting real-time performance in highly dynamic scenarios.

Such adversarial disruptions degrade system performance by corrupting control inputs and state measurements, ultimately threatening stability and consensus in networked robotic systems. To overcome these limitations, a novel discrete-time adaptive control framework is proposed that ensures reliable tracking and stability under both uncoupled and coupled robot dynamics. The approach integrates a modified graph-theoretic structure with node-dependent weighting to capture heterogeneous robot interactions, while explicitly modeling attack effects within the system dynamics. An adaptive control law is developed using a nonlinear basis function approximation to handle unknown system uncertainties, along with a dynamic weight update mechanism that compensates for adversarial disturbances in real time. For the uncoupled case, stability is established through a composite Lyapunov function incorporating logarithmic and quadratic terms, guaranteeing boundedness of all closed-loop signals and asymptotic convergence of the tracking error. This framework is further extended to systems with coupled dynamics by introducing an auxiliary estimation mechanism to reconstruct unmeasurable interactions, leading to a unified adaptive controller capable of mitigating both internal uncertainties and external attacks. Rigorous Lyapunov-based analysis demonstrates that the proposed method ensures asymptotic tracking performance despite the presence of Byzantine disturbances. Numerical simulations validate the theoretical results, showing improved resilience, accurate trajectory tracking, and enhanced robustness compared to existing approaches.","url":"https://doi.org/10.3390/act15070368","authors":["Shahid Hussain Gurmani","Somayya Komal","Waqar Ul Hassan","Afreen Bibi","Muhammad Jabir Khan","Meshal Shutaywi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-03T07:59:47Z","doi":"10.3390/act15070368","addedAt":"2026-08-31T06:34:12.795Z","updatedAt":"2026-08-31T06:34:12.795Z"},{"id":"doi:10.1109/roman.2009.5326257","name":"Improvement of linear actuator with ER gel","source":"crossref","abstract":"","url":"https://doi.org/10.1109/roman.2009.5326257","authors":["Kentarou Sato","Ken'ichi Koyanagi","Yasuhiro Kakinuma","Hidenobu Anzai","Koji Sakurai","Toru Oshima"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-11-19T00:35:32Z","doi":"10.1109/roman.2009.5326257","addedAt":"2026-08-31T06:34:12.795Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1088/1748-3182/7/3/036007","name":"Magnetic fish-robot based on multi-motion control of a flexible magnetic actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1088/1748-3182/7/3/036007","authors":["Sung Hoon Kim","Kyoosik Shin","Shuichiro Hashi","Kazushi Ishiyama"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-05-01T16:13:27Z","doi":"10.1088/1748-3182/7/3/036007","addedAt":"2026-08-31T06:34:12.795Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/icarm52023.2021.9536159","name":"Development of A Novel Dual-arm Robot via Modular Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icarm52023.2021.9536159","authors":["Weijun Wang","Jiangtao Hu","Xiaofeng Yang","Tian Xie","Chaoyang Ma","Wenjie Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-09-15T20:52:41Z","doi":"10.1109/icarm52023.2021.9536159","addedAt":"2026-08-31T06:34:12.795Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.23919/icep.2017.7939355","name":"Thermal management of silicon micro robot driven by neural networks IC control SMA actuator","source":"crossref","abstract":"","url":"https://doi.org/10.23919/icep.2017.7939355","authors":["M.

Despite the inherent capabilities of soft materials, embedding reliable sensing in soft actuators or robots could introduce constraints in the overall design (e.g., loss of deformability, undesired trajectories, etc.) or reduce their compliant characteristics. Consequently, an adequate stiffness for both sensor and actuator becomes a crucial design parameter. In particular, for sensing the deformation related to actuation motion, sensing and actuating strategies must work in full mechanical synergy. In this view, an inductive sensing solution is presented, exploiting open-cell foam and a copper (Cu) wire in an Inductive Foam Sensor (IFS). Due to entangled air cells high deformability is enabled upon vacuum pressure, and proprioceptive information is provided. The IFS is then successfully integrated into the earlier developed Ultralight Hybrid Pneumatic Artificial Muscle (UH-PAM), which encases an elastomeric bellow skin and plastic rings. Such sensorized UH-PAM (SUH-PAM) is capable of a high contraction ratio (54% upon −80 kPa), while the inductive sensing shows a high sensitivity of 0.01031/1% and a hysteresis of 5.35%, with an average error of 1.85%, respectively. In order to implement a robust feedback control system, an adaptable proportional sliding mode control is presented. As a result, the SUH-PAM motion can be controlled to the mm-scale, with an RMSE of 0.925 mm, and high robustness against disturbances is demonstrated.","url":"https://doi.org/10.3389/frobt.2021.742885","authors":["Seonggun Joe","Hongbo Wang","Massimo Totaro","Lucia Beccai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-05-30T10:22:25Z","doi":"10.3389/frobt.2021.742885","addedAt":"2026-08-31T06:34:12.795Z","updatedAt":"2026-08-31T06:34:24.577Z"},{"id":"doi:10.1109/robot.1998.680894","name":"Pneumatic muscle actuator technology: a light weight power system for a humanoid robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1998.680894","authors":["D.G.

A variable-stiffness actuator has been implemented to add controlled compliance in the gripper’s operation allowing the combining of various grasping and manipulation tasks. First, we analyze the specific application-determined task requirements, focusing on the need for adaptive flexibility and the role of compliant elements in the design. The chosen solution is a simple planar mechanism, equipped with one standard and one variable-stiffness actuator.

A heterogeneous fixed-time prescribed performance formation control framework is proposed to ensure precise coordination among the vehicles. Specifically, a disturbance observer-based fixed-time control law is developed for USV formation control, employing a leader-follower topology. Simultaneously, a fixed-time prescribed performance control strategy based on error transformation is designed for the UAVs to ensure convergence within specified performance boundaries. To enhance system resilience, a disturbance observer is designed for the USV formation system to handle complex marine environmental disturbances. Meanwhile, for the UAV subsystem, an adaptive fault-tolerant mechanism is integrated to estimate and compensate for loss of actuator efficiency and bias faults. Lyapunov stability analysis theoretically proves that all tracking errors in the closed-loop system converge to a small neighborhood of the origin within a fixed time, independent of the initial system states. The simulation results validate the effectiveness of the proposed formation methods.","url":"https://doi.org/10.20517/ir.2026.12","authors":["Zihao Liang","Weixiang Zhou","Yandan Wang","Yayu Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-25T08:37:37Z","doi":"10.20517/ir.2026.12","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1109/robio.2018.8664759","name":"A Mechanism of Single Actuator Snakeboard Robot and its Curving Motion Generation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio.2018.8664759","authors":["Satoshi Ito","Sam Kiely","Shoya Sugiura","Jun Yabuki","Yuya Masuda","Ryosuke Morita"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-03-18T20:01:56Z","doi":"10.1109/robio.2018.8664759","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1115/imece2017-70665","name":"Joint Torque Control of a Collaborative Robot Based on Active Disturbance Rejection With the Consideration of Actuator Delay","source":"crossref","abstract":"The application of a robot manipulator to the task of parts assembling or collaboration with human workers requires compliant control and intrinsic safety. As a result, it is necessary to exert accurate torque on each joint of the robot through torque sensing and implementing closed-loop joint torque control. This torque servo system is required to track reference torque signals while operating under the influence of motor friction, flexibility of the harmonic drive, noise from the sensor, robot dynamics modelling error and other unknown certainties, resulting in large control efforts. This paper focuses on providing better compliance control for collaborative robots and proposes a joint torque controller design under development with active disturbance rejection concept. The controller is designed through a novel extended state observer to estimate and compensate for the unmodelled dynamics of the system, nonlinearly variable motor friction, and other uncertainties. Then, a simple proportional differential controller is designed to produce control law. In spite of the remarkable performance in dealing with the mechanical dynamics of the joint actuator, the original controller does not work well with the electrical factor of the joint actuator due to the limited current loop bandwidth in the hardware of motor and driver. To eliminate the detrimental effect of the time delay in current servo, a predictive output method based on a nonlinear tracking differentiator (TD) is used to improve the controller within the framework of active disturbance rejection control. Both simulations and experiments are conducted on a prototype one degree of freedom manipulator with a joint torque sensor. The results demonstrate the enhancement of both the system stability and disturbance rejection performances. Based on the proper treatment of actuator delay, the dominant effect of the motor friction and the flexibility of the harmonic drive has been reduced to insignificance. Moreover, the proposed controller is easy to implement because the explicit dynamic model of the system is not required.","url":"https://doi.org/10.1115/imece2017-70665","authors":["Tianyu Ren","Yunfei Dong","Dan Wu","Guolei Wang","Ken Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-01-10T21:13:22Z","doi":"10.1115/imece2017-70665","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/e23060751","name":"Sensor and Actuator Fault Diagnosis for Robot Joint Based on Deep CNN","source":"crossref","abstract":"This paper proposes a data-driven method-based fault diagnosis method using the deep convolutional neural network (DCNN).

In order to achieve the above goal, the fused data of sensors and actuators are used, where both types of fault are described in one formulation.

In order to verify the effectiveness of the proposed deep convolutional neural network model, different fault diagnosis methods including support vector machine (SVM), artificial neural network (ANN), conventional neural network (CNN) using the LeNet-5 method, and long-term memory network (LTMN) are investigated and compared with DCNN method.

Therefore, they are large in size and heavy. Haptic devices using asymmetric vibrations can display illusion forces with mobile structures. However, they need additional structures (comprising actuators) to generate a 3D illusion force; however, the operational mechanism becomes complex. To solve this problem, we propose the use of a 3-degree-of-freedom (3DOF) oscillatory actuator that can generate a 3DOF vibration using only one actuator. This study describes the basic characteristics and operating verification of the 3DOF oscillatory actuator. The static thrust characteristics are quantified and analyzed using a finite element method. The dynamics are calculated based on numerical simulations using a dynamic model.

This device is referred to as the “flipper.” The flipper is connected to a rotational motor, and its shape is similar to that of the real fish's fins. The flipper using the propulsion mechanism proposed in this study has 1 degree of freedom. We can control the test robot during forward motion as well as its direction-changing operation. The experimental test robot is composed of a flipper at the front of the robot's head, together with a body and a tail/vertical fin. The electronic components are installed into the body. The tail functions to maintain the horizontal/vertical balance of the robot. Forward propulsion is achieved through the rotation of the flipper. The robot's direction can be changed by repeated oscillation of the flipper in a direction opposite to that of the desired angle. Several experiments were performed to measure the thrust force of the experimental robot and its motion characteristics in a test water pool. The experimental results show that the proposed propulsion method is viable.&lt;def-list&gt; Nomenclature &lt;def-item&gt; &lt;term&gt; F T &lt;/term&gt; &lt;def&gt; = Thrust &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; F I &lt;/term&gt; &lt;def&gt; = Inertia force &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; F B &lt;/term&gt; &lt;def&gt; = Buoyancy &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; B V &lt;/term&gt; &lt;def&gt; = Platform volume &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; V target &lt;/term&gt; &lt;def&gt; = Target speed &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; ρ &lt;/term&gt; &lt;def&gt; = Water density &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; P &lt;/term&gt; &lt;def&gt; = Flipper pitch &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; D &lt;/term&gt; &lt;def&gt; = Drag force &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; C D &lt;/term&gt; &lt;def&gt; = Drag coefficient &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; A &lt;/term&gt; &lt;def&gt; = Projection of the frontal area &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; T &lt;/term&gt; &lt;def&gt; = Effective power &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; P m &lt;/term&gt; &lt;def&gt; = Propeller power &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; C M &lt;/term&gt; &lt;def&gt; = Center of total body mass &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; C B &lt;/term&gt; &lt;def&gt; = Center of buoyancy &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; C F &lt;/term&gt; &lt;def&gt; = Center of flipper mass &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; F DS &lt;/term&gt; &lt;def&gt; = Restoring force &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; g &lt;/term&gt; &lt;def&gt; = Gravity &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; Q &lt;/term&gt; &lt;def&gt; = Motor torque at maximum revolutions per minute &lt;/def&gt; &lt;/def-item&gt; &lt;def-item&gt; &lt;term&gt; rps reasonable &lt;/term&gt; &lt;def&gt; = Reasonable revolutions per second &lt;/def&gt; &lt;/def-item&gt; &lt;/def-list&gt;","url":"https://doi.org/10.4031/mtsj.51.5.11","authors":["Myoung-Jae Jun","Chang-Soo Han"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-11-08T04:32:09Z","doi":"10.4031/mtsj.51.5.11","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.4028/www.scientific.net/amr.482-484.529","name":"Actuator Fault Detection and Isolation for Robot Manipulators with the Adaptive Observer","source":"crossref","abstract":"The fault detection and isolation (FDI) for industrial robot manipulators, subject to faults of actuator, is devised in this paper.

First, dynamic modeling of the robot is accomplished using the Lagrange method. To measure the position and velocity, a super-twisting third-order sliding mode (STW-TOSM) observer is applied. The proposed scheme can accommodate both faults and uncertainties without velocity measurement. In addition, fast convergence and high accuracy is achieved because of applying the high-order sliding mode (HOSM) observer. In order to indicate the effectiveness of the FTC on the basis of nonlinear H∞, its performance is compared with conventional sliding mode and feedback linearization methods. The obtained results reveal the efficacy of the proposed FTC- H∞.","url":"https://doi.org/10.15406/iratj.2020.06.00210","authors":["Mahmood Mazare","Mostafa Taghizadeh","Pegah Ghaf G"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-03-18T03:36:04Z","doi":"10.15406/iratj.2020.06.00210","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1299/jsmermd.2018.2a1-j10","name":"Investigation of position of pulleys for tendon-driven jumping robot by single actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmermd.2018.2a1-j10","authors":["Kouki Takai","Takashi Takuma"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-12-24T22:55:09Z","doi":"10.1299/jsmermd.2018.2a1-j10","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/robio.2011.6181552","name":"A robot hand using electro-conjugate fluid: Imitating a palm motion of human hand using soft balloon actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio.2011.6181552","authors":["Akihiro Yamaguchi","Kenjiro Takemura","Shinichi Yokota","Kazuya Edamura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-04-13T15:36:46Z","doi":"10.1109/robio.2011.6181552","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.5136/lifesupport.18.supplement_155","name":"Study on Actuator for Rehabilitation Robot with Multi-Motor","source":"crossref","abstract":"","url":"https://doi.org/10.5136/lifesupport.18.supplement_155","authors":["Yukio Saito","Hirokazu Minai","Toshimasa Haneyoshi","Atsushi Umemura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-08-04T10:09:36Z","doi":"10.5136/lifesupport.18.supplement_155","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/roman.2012.6343725","name":"A novel variable impedance compact compliant series elastic actuator for human-friendly soft robotics applications","source":"crossref","abstract":"","url":"https://doi.org/10.1109/roman.2012.6343725","authors":["S.

To cope with such requirements, soft actuators have been developed, most of which utilize elastic deformation of a rubber tube or balloon caused by compressed air pressure. Such a pneumatic rubber actuator is expected to be effectively used as a flexible and friendly soft actuator in various fields. In this study, to realize a flexible pneumatic carrier system, a soft planar actuator using rubber balls has been developed assuming that the actuator directly contacts carried objects. This paper describes a fundamental principle of operation, a control method and experimental results. Additionally, a small sized soft planar actuator made of silicone rubber is described. The results show the effectiveness of the proposed actuator mechanism.","url":"https://doi.org/10.20965/jrm.2000.p0254","authors":["Toshiro Noritsugu","Daijyu Kaneshiro","Takashi Inoue"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-04-14T02:17:00Z","doi":"10.20965/jrm.2000.p0254","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/raiic59453.2023.10281184","name":"Adaptive Parameter Estimation of Robot with Actuator and Friction Dynamics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/raiic59453.2023.10281184","authors":["Yueming Fang","Hu Deng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-10-17T17:47:18Z","doi":"10.1109/raiic59453.2023.10281184","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.29327/118637.1-7","name":"Antagonistic torsion spiral springs variable stiffness actuator - ATOSS VSA","source":"crossref","abstract":"","url":"https://doi.org/10.29327/118637.1-7","authors":["David Roy RICHARDS","Victor Augusto KICH","Rodrigo Da Silva GUERRA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-08-13T22:23:46Z","doi":"10.29327/118637.1-7","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/sta.2017.8314837","name":"A fault tolerant control for robot manipulators against actuator fault","source":"crossref","abstract":"","url":"https://doi.org/10.1109/sta.2017.8314837","authors":["Aymen Elghoul","Adel Tellili","Adel Bouziri","Mohamed Naceur Abdelkrim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-03-19T18:05:36Z","doi":"10.1109/sta.2017.8314837","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1163/016918610x493651","name":"Cascaded Feedback Control Scheme for Trajectory Tracking of Robot Manipulator Systems with Actuator Dynamics","source":"crossref","abstract":"","url":"https://doi.org/10.1163/016918610x493651","authors":["Jinwoo Jun","Katsuya Kanaoka","Sadao Kawamura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-04-27T23:34:20Z","doi":"10.1163/016918610x493651","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/wcica.2018.8630720","name":"A Multi-actuator Soft Robot Inspired by Young Tiger Beetle","source":"crossref","abstract":"","url":"https://doi.org/10.1109/wcica.2018.8630720","authors":["Bingbing Hu","Guoqing Jin","Zijing Liu","Pengbo Wang","Xiangpeng Li","Deshan Wang","Lining Sun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-02-28T23:14:48Z","doi":"10.1109/wcica.2018.8630720","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1007/s40815-017-0358-2","name":"Adaptive Impedance Force Controller Design for Robot Manipulator including Actuator Dynamics","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s40815-017-0358-2","authors":["Zong-Yu Jhan","Ching-Hung Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-08-01T07:18:58Z","doi":"10.1007/s40815-017-0358-2","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/iccas.2015.7364579","name":"Control strategy of slack enabling tendon actuator for the soft wearable robot using feedback linearization","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iccas.2015.7364579","authors":["Useok Jeong","Haemin Lee","Hyunki In","Kyu-Jin Cho"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-12-28T16:34:00Z","doi":"10.1109/iccas.2015.7364579","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/icrom.2013.6510147","name":"Dynamics model and control of underwater fish-like micro mobile robot with PZT actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icrom.2013.6510147","authors":["A.

Furthermore, because external forces can be precisely measured through pressure sensors, the bellows actuator works as a force sensor. In order to use the bellows actuator as a force sensor (bellows sensor), we investigate the static and dynamic characteristics of the bellows actuator. Based on these experimental results, the capability of the bellows sensor becomes clear. We use the bellows actuator as a sensing actuator which works as a sensor and an actuator simultaneously. In addition, the effectiveness of the actuator is demonstrated through several experimental results. We design one joint of a robot which is antagonistically activated by the two bellows actuators. Based on some experimental results, we disclose the static and dynamic characteristics of the proposed robot and confirm that it can move flexibly following external forces by utilizing the force sensing ability.","url":"https://doi.org/10.20965/jrm.1995.p0474","authors":["Yasuhiro Hayakawa","Sadao Kawamura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-04-14T06:14:18Z","doi":"10.20965/jrm.1995.p0474","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.1109/icra.2017.7989710","name":"Steerable miniature legged robot driven by a single piezoelectric bending unimorph actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2017.7989710","authors":["Audelia G.

These advantages have led to a significant growth in the number of procedures that are performed annually. However, it is still challenging to position a catheter in a target vessel branch within the highly complicated and delicate vascular structure. In fact, vessel tortuosity and angulation, which cause difficulties in catheterization and reaching the target site, have been reported as the main causes of failure in endovascular procedures. Maneuverability of a catheter for intravascular navigation is a key to reaching the target area; ability of a catheter to move within the target vessel during trajectory tracking thus affects to a great extent the length and success of the procedure. To address this issue, this paper models soft catheter robots with multiple actuators and provides a time-dependent model for characterizing the dynamics of multi-actuator soft catheter robots. Built on this model, an efficient and scalable optimization-based framework is developed for guiding the catheter to pass through arteries and reach the target where an aneurysm is located. The proposed framework models the deflection of the multi-actuator soft catheter robot and develops a control strategy for movement of catheter along a desired trajectory. This provides a simulation-based framework for selection of catheters prior to endovascular catheterization procedures, assuring that given a fixed design, the catheter is able to reach the target location. The results demonstrate the benefits that can be achieved by design and control of catheters with multiple number of actuators for navigation into small vessels.","url":"https://doi.org/10.3389/frobt.2021.772628","authors":["Seyede Fatemeh Ghoreishi","Ryan D.

Due to this a user may have limited to the usage of such devices within set rehabilitation sessions as opposed to a continual usage. The purpose of this review is therefore to find which actuator implementations would be most suitable for a simplistic, low-cost powered orthoses capable of assisting those with pathologic gait disorders by collating literature from Web of Science, Scopus, and Grey Literature. In this systematic review paper 127 papers were selected from these databases via the PRISMA guidelines, with the financial costs of 25 actuators discovered with 11 distinct actuator groups identified. The review paper will consider a variety of actuator implementations used in existing lower-limb exoskeletons that are specifically designed for the purpose of rehabilitating or aiding those with conditions inhibiting natural movement abilities, such as electric motors, hydraulics, pneumatics, cable-driven actuators, and compliant actuators. Key attributes such as technical simplicity, financial cost, power efficiency, size limitations, accuracy, and reliability are compared for all actuator groups. Statistical findings show that rotary electric motors (which are the most common actuator type within collated literature) and compliant actuators (such as elastic and springs) would be the most suitable actuators for a low-cost implementation. From these results, a possible actuator design will be proposed making use of both rotary electric motors and compliant actuators.","url":"https://doi.org/10.1007/s10846-022-01695-0","authors":["T.

This twist drive actuator mechanism is composed of two small-diameter round belts with opposite configurations located near the joint. The two round belts are twisted by using individual DC motors; thus, the joint is activated because of the contraction forces generated by the twisting process. Experimental results, obtained using the proposed single-link robot, demonstrate that the joint can be controlled with a high position resolution by increasing and decreasing the amount of twisting. Using the experiments, we reveal that the antagonistic twist drive actuator system has a secondary role in speed reduction, which is capable of decreasing the velocity of the joint movement significantly. In addition, we indicate a linear relationship between the twist rotation and the joint angle of the robot. Furthermore, this paper formulates the Young’s modulus of the round belt used in the twist drive actuator. We demonstrate that the Young’s modulus decreases gradually with respect to the increase in the twisting of the round belt. Finally, we demonstrate a successful position control of the robotic joint, and the traditional PI controller is capable of suppressing the oscillatory motion by using a one-sided twin-twisted configuration.","url":"https://doi.org/10.20965/jrm.2016.p0842","authors":["Takahiro Inoue","Ryuichi Miyata","Shinichi Hirai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-12-20T00:31:52Z","doi":"10.20965/jrm.2016.p0842","addedAt":"2026-08-31T06:34:13.640Z","updatedAt":"2026-08-31T06:34:13.640Z"},{"id":"doi:10.54732/jeecs.v11i1.8","name":"Rehabilitation Hand Exoskeleton Robot based on Soft Actuator and Adaptive Control","source":"crossref","abstract":"Every year, millions of people suffer from severe motor impairment in the hand as a result of strokes or spinal cord injuries, which hinders their ability to perform simple daily activities.

Firstly, the topology, geometries and elastic energies of shape shifting are analyzed for the three kinds of origami flexiballs with extruded outward rhombic faces. Provably, they meet the definitions of reconfigurable and transformable metamaterials with switchable stiffness and multiple degrees of freedom. Secondly, a new type of soft actuator with rhombic deformations is successfully put forward, different from soft bionic deformations like elongating, contracting, bending, twisting, spiraling, etc. Further, we redesign and fabricate the three-dimensional (3D) printable structures of origami flexiballs considering their 3D printability and foldability, and magnetically actuated them through the attachment of magnetoactive elastomer. Lastly, a fully soft in-pipe robot prototype is presented using the origami flexiball as an applicable attempt. Experimental work clearly suggests that the presented origami flexiball robot has good adaptability to various pipe sizes, and also can be easily expanded to different scales, or reconfigured into more complex metastructures by assembly.

These sub-functions are critical for achieving stable and efficient gaits in both humans and robots, facilitating advancements in biomechanical research and the development of more effective robotic systems and assistive devices. In this thesis, we select hopping to focus on the Stance subfunction, which involves the elastic rebounding of the stance leg, counteracts gravity, and provides vertical propulsion. Within a broader context of locomotion, hopping stands out as a particularly fundamental movement due to its simplicity while its biomechanical and control aligns with other forms of bipedal and quadrupedal locomotion, such as running. Hopping involves repeated, rhythmic movements primarily in one dimension (vertically), allowing researchers to isolate and examine the dynamics of vertical displacement. This simplification aids in modeling, simulating, and understanding the fundamental principles of dynamic legged locomotion. Mechanical structure and motor control are the ingredients of locomotion generation. On one hand, actuator design, morphology (e.g., body segmentation), coupling between different mechanical elements, compliance, and passive dynamics role in facilitating movement generation are key aspects of the mechanical design of a locomotor system. On the other hand, appropriate motor control can complement well-designed mechanics to reach an efficient, robust, and agile motion. Human musculoskeletal and neural control can be used as a role model to design hopping robots. Therefore, investigating how human mechanics and motor control contribute to hopping in a variety of conditions and using these insights to design and control bioinspired hopping robots are the overlaying concepts of this thesis. To address the above mentioned research concepts, we first investigated human hopping to understand its variability and underlying mechanics. In our initial experiments, subjects hopped at various frequencies, choosing their own hopping characteristics such as frequency and height. We analyzed ground reaction forces, hopping times, and duty factors, observing significant variability both between subjects and within the same subject under different conditions. When subjects hopped to a metronome, intra-subject variability decreased, indicating that consistent rhythmic pacing stabilizes hopping behavior. We found minimal variability between 100 % and 150 % of the Preferred Hopping Frequency (PHF), but variability increased significantly at 75 % PHF. The second study focused on the actuation and compliance role at different joints in the hopping experiment of first study. The kinematic and kinetic measurements were used to create a mechanical simulation model with Series Elastic Actuators (SEAs) to optimize joint stiffness for minimizing peak power and energy consumption. Our results showed that while fixed stiffness values were effective for the knee and ankle, adjustable stiffness could further reduce energy requirements. Optimal SEA stiffness reduced peak power demands by up to 73 % at the ankle and 66 % at the knee, particularly around the preferred hopping frequency, though no significant benefits were found for the hip at higher frequencies. Further investigations focused on the roles of passive dynamics and active control properties at different leg joints during hopping. Our analysis suggested that distal joints, like the ankle, benefit more from passive elastic elements, while proximal joints, such as the knee and hip, require active control mechanisms for effective energy management. Using force-modulated compliance (FMC) alongside fixed springs, we accurately predicted knee torque-angle patterns across various frequencies. In addition to studying human mechanical design and motor control in steady-state hopping, we investigated ground-level perturbation scenarios to unders","url":"https://doi.org/10.26083/tuprints-00029047","authors":["Mohammadi Nejad Rashty, Aida"],"tags":["500","570","620"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.26083/tuprints-00029047","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.48550/arxiv.2605.17681","name":"PRIME: Physically-consistent Robotic Inertial and Motion Estimation for Legged and Humanoid Robots","source":"datacite","abstract":"Humanoid and legged robots interact with the environment through intermittent contacts, making accurate motion estimation fundamentally dependent on reasoning about contact dynamics.

As a result, purely kinematic reconstructions often violate rigid-body dynamics, particularly during contact-rich motions. To enable accurate motion estimation from onboard kinematics in real-world deployment, we propose PRIME (Physically-consistent Robotic Inertial and Motion Estimation), a Maximum A Posteriori (MAP) formulation that refines measured kinematics and actuator commands into a dynamically consistent trajectory while jointly estimating frictional contact forces and physically consistent inertial parameters. Our approach incorporates differentiable contact dynamics with smoothed complementarity constraints and an Anitescu-style friction model, yielding a smooth optimization problem that remains tractable across versatile contact transitions. We evaluate PRIME on contact-rich locomotion with quadrupedal robots and the Unitree G1 humanoid, demonstrating improved trajectory consistency and accurate inertial parameter identification. Beyond improving state estimation and feedback control with calibrated inertial parameters, PRIME produces force- and contact-annotated motion reconstructions from real robots in deployment, which can be used to provide high-quality data for downstream learning applications, including large-scale behavior modeling and robot foundation models.","url":"https://doi.org/10.48550/arxiv.2605.17681","authors":["Kang, Jiarong","Ren, Kunzhao","Pang, Tao","Xiong, Xiaobin"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2605.17681","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:16.227Z"},{"id":"doi:10.48550/arxiv.2605.16056","name":"Health-Conditioned Vision-Language-Action Models for Malfunction-Aware Robot Control","source":"datacite","abstract":"Research on Vision Language Action (VLA) models has been increasing rapidly in recent years.

These make them highly suitable for safe physical human-robot interaction and collaboration. However, such actuation approach introduces a number of challenges to be overcome in order to capitalize on their advantages. These include some inherent uncertainties regarding their dependability, which mainly result from the combination of possible changes in the drive train caused by wear, unavoidable system model inaccuracies, and the high mechanical elasticities facilitating oscillations in the joints. It is shown that the resulting challenges, in particular influencing the performance in velocity estimation, robust torque transmission, trajectory control, and human-robot collaboration, can to a large extent be overcome. Thereby, achieving dependable usage of such robots marks a key step towards utilizing their unique high safety features for physical human-robot collaboration in industrial applications. In order to get an insight into the safety capabilities as a collaborative robot, a risk analysis according to the new ISO/TS 15066 has been performed comparing the class of tendon driven ultra lightweight series elastic robots with downscaled and stiff robots. Further, the influence of high compliance during contact situations has been demonstrated during a collision test. In lightweight and downscaled robotic structures, the suitable joint position sensor size is limited, resulting in a relatively coarse discrete position signal. Furthermore, joint elasticities facilitate fast and oscillating motions containing a broad bandwidth of frequencies and velocities. In order to effectively damp the controlled motion and also for model-based computations, an accurate velocity estimation is essential. Kalman filter approaches already showed accurate performance in position signal based velocity estimation, but within a small bandwidth that correlates with the filter's measurement variance parameter. In order to create an estimation approach more suitable for the considered concept of tendon driven series elastic actuation, the velocity and frequency dependent optimal measurement variance parameter has been analyzed. The observed parameter characteristics serve as the basis for the proposed new measurement variance update rule. The resulting novel adaptive Kalman filter approach adapts better to the investigated application than the compared state-of-the-art approach. It produces a smoother and more accurate velocity estimation, as will be demonstrated in virtual and real robot experiments. In biologically inspired mechanical structures, tendons are used to transmit forces along a kinematic chain, which must satisfy high robustness requirements by simultaneously allowing small pulley radii. Cables or belts are often not applicable due to size and force requirements in contrast to thin synthetic fiber ropes. Besides the breaking force, only a little information about the ropes is provided by the manufacturer. Thus, further research is required to investigate whether a rope is suitable to be used as a reliable component of a drive train which mainly depends on its elongation behavior. In this regard, new systematic creep experiments regarding different materials, manufacturers, and diameters, as well as bending experiments are presented in this work. The findings obtained for the rope characteristics support the material selection decisions during the system design process and give insights into the long-term behavior. In order to monitor the long-term behavior, an observer approach is presented which does not need joint torque measurements but nevertheless enables elongation detection in tendon driven kinematic chains even subject to model inaccuracies. This has been demonstrated in simulated and real robot experiments.

To fulfill this need, efforts are made to increase the cognitive abilities that robots lack to autonomously interpret their environment and human intentions. But equally important, new hardware and actuation designs are required to increase the safety and sensitivity of robots that operate in the vicinity of humans. A main restriction of most current robot arm designs for physical human-robot interaction (pHRI) is the discrepancy of safety and dynamic performance in terms of, for instance, velocity and payload. This thesis therefore deals with the challenges involved in the development of fast robot arms that are safe for the operation in human-centered environments and for applications requiring close pHRI. It presents design guidelines for lightweight robot arms with elastic tendon actuation and, additionally, suitable methods for dynamic modeling and control and safety evaluation. This novel type of robotic arm aims at enabling automation of applications that combine critically high safety requirements for pHRI with high performance and flexibility demands. The BioRob-X4 robot arm is used as a robotic hardware platform for evaluation of the developed models and methods, which are tested in simulation and validated on the robot hardware. In contrast to other robot arm designs, the actuation principle of the BioRob arm is non-modular in order to enable an extreme lightweight and low-inertia design with high safety and acceleration properties. The use of tendons spanning multiple joints, however, introduces kinematic coupling and the use of extension coil springs to maintain tendon tension and to decouple link and rotor inertia introduces undesirable joint oscillations. These effects have to be modeled accurately to investigate the behavior of the actuators and the whole arm dynamics in theory, simulation, and experiment and to allow for the development and design of model-based algorithms. Therefore, detailed mathematical models for the highly compliant and kinematically coupled tendon actuators and the low inertia link structure are developed and validated against experimentally measured data. The actuation models are analyzed with respect to highly dynamic motions inherent to low inertia link designs. Associated effects such as dynamic and static tendon slackening are discussed and from these considerations, guidelines for shaping the actuator characteristic output curves are derived. State space partitioning of the manipulator is proposed for the formulation of the full robot arm dynamics model. By partitioning the model into three state spaces, the dynamics model of the robot arm can be formulated in joint space by reflecting the model states and parameters to the joint space. The presented approach is generally applicable to tendon-driven robotic arms and, furthermore, helpful in reducing the modeling complexity. The design and hardware constraints of the investigated robot arm demand for the development of specific calibration and filter methods for the joint position and velocity states. Thus, a joint position sensor calibration method and a multilevel switching observer are developed that are both in general applicable to robotic arms with high joint elasticity. Based on the inverse dynamics model and the decoupling of tendon actuators spanning multiple joints we derive a position tracking controller by using the developed state space model segmentation. The proposed observer and control methods are evaluated in simulation and on the robot hardware. A new prediction method for maximum collision and clamping forces based on the current dynamic state of the manipulator and its compliant actuators by monitoring also the potential energy stored in the springs is developed and applied successfully. A worst case safety evaluation considering the possibility of software and hardware failures is performed.

The report proposes a three-phase transition model in which the human labour ecosystem created during early robotics expansion is itself progressively compressed through autonomous diagnostics, standardised deployment, robot-to-robot servicing, autonomous logistics integration, and cloud-based orchestration systems. Key themes explored in Volume II include: • labour compression within the robotics sector itself• SME continuity under demographic labour scarcity• adaptive operational inference within small business environments• autonomous deployment frameworks (“the robot arrives on a bus”)• lease moonlighting and multi-tenant robotic utilisation• orchestration-layer concentration risk• infrastructure and energy dependence• regulatory latency• and the emergence of robotics as ambient economic infrastructure The analysis argues that in many ageing economies, robotics deployment may increasingly function not primarily as labour elimination, but as labour-substitution infrastructure required to sustain sectors facing structural workforce scarcity.

For my capstone project, my team designed a robot for the ASME Student Design Competition to address the world's growing waste crisis. We created a small-scale remote-controlled robot that can collect waste in extreme conditions. For my STS research paper, I looked at how public perception influenced the development and implementation of nuclear energy. My research was driven by the urgency of climate change and the necessity for sustainable solutions to achieve a positive public image to ensure long-term viability. These topics are linked by their relationship to improving the environment, emphasizing that solutions will require a broad, multidisciplinary approach. As an engineer, it is essential to be aware of the environmental impact of projects, as well as how the technology is viewed and adapted by the public. For our capstone project, we had to design a robot capable of navigating a model city and collecting trash and depositing it into designated waste receptacles. This project was heavily constrained by strict size limits, as the course's height restrictions could range from six to twelve inches, with the road lanes ranging from four to six inches. This was further complicated with some additional extreme conditions, such as varied road materials, large potholes, steep hills, and the physical waste being any material from light plastic to solid steel. Our solution involved a robot powered by a 12V battery, with tank drive wheels to move and an ESP32 chip as the brain. The robot also had a turntable at the front, which had an arm mechanism mounted to it with an extendable claw on it. This allowed for bins to be picked up from any side of the vehicle and at further distances from the vehicle, particularly down narrow alleys the robot couldn’t traverse. This arm also doubled as the actuator to dump the holding bin where waste was stored. We manufactured the device primarily out of 3D-printed parts to ensure flexible design and the ability to rapidly tweak parts. This approach was essential for managing the mechanical complexity of the arm and turntable while maintaining the robot's strict size requirements. In final testing and competition, the robot successfully navigated the model environment and fulfilled the primary objectives of waste collection and deposition. A significant technical success was the communication architecture, which utilized the ESP-NOW protocol. We were able to achieve a low-latency, robust wireless link between the controller and the vehicle’s motor systems. While we were able to complete all objectives, there were a few minor issues, primarily a result of design compromises due to the project’s complexity. The width of the robot was half an inch wider than the minimum lane width due to the mechanical density of all the necessary mechanisms. Additionally, lifting heavy waste containers was very challenging due to the low weight of the robot, and the robot was also unable to climb the most extreme grade hills. The choice of 3D-printed components proved invaluable, allowing easy tweaking and improvement throughout the design and prototyping process. My research investigates how public perception influences technology adoption, specifically by examining the stalled implementation of nuclear energy. As we seek ways to lower carbon emissions, nuclear energy stands out as a key asset in that objective. Despite nuclear energy's potential for power generation, it is not widely adopted due to societal pressures; the public does not support the technology, even though engineers have shown it is very safe. I approach this by looking at the events of Chernobyl as a case study, and using that to determine relevant stakeholders such as government regulators and local communities.

In gross/hard manipulation, robotic tasks are denned by motion commands based on predefined and precise positions. In this case, the high-level task control typically adopts an open-loop approach where low-level servo controllers drive the robot with the objective of achieving a predefined joint trajectory that is consistent with the task trajectory as planned at an upper level, but the sensory information is not fed into the task level of the robot control system. In flexible manipulation, as defined in this thesis, robot motion cannot be pre-defined in terms of precise positions and motions, due to task uncertainties. Then, feedback of sensory information to upper levels of the control system, with appropriate preprocessing and abstraction, will facilitate high-level task control and improved process performance. Control systems of the existing commercial robots by and large fall into the category of gross/hard manipulation, with associated shortcomings. Focus of the present research is on fine/flexible manipulation, which is important in robotic processing of flexible and inhomogeneous, natural materials, such as fish and meat, where, the detection of material properties and transition regions in the processed object is usually important for high-level, intelligent task control. Mechanical impedance at the process interface of a robotic task, is considered to provide the information that is needed in detecting the required process characteristics, and is investigated as a significant sensing approach in flexible manipulation. The research presented in this thesis concerns technology development for flexible manipulation of robotic processes. The main goals of the present research are threefold; (1) investigate and develop an impedance-based task sensing method for flexible manipulation, (2) investigate, design, and develop a control architecture that has the capability of on-line task monitoring and interpretation, high-level feedback of information, and knowledge-based decision making, which is suitable for executing flexible manipulation of robotic processes, and (3) implement and evaluate the developed sensing and control system technologies with regard to practical applications. To achieve these objectives, the following tasks are carried out: Analytical framework for dynamics, sensing, and control. Models are formulated for robot dynamics and process impedance, with linearizing feedback and task separation for gross motions and fine manipulation. This framework is intended for facilitating on-line estimation of process impedance and implementation of knowledge-based task monitoring and control. Impedance sensing technologies. Methods of estimating mechanical impedance at the process interface of a robotic processing task are developed, which use actuator effort and the joint motion signals as the input information to the estimator. Methods of signal conditioning and estimation are developed based on the Kalman filter approach. Further interpretation and utilization of impedance information at the task level is made through knowledge-based decision making. This is intended to accommodate task uncertainties, specifically, position variables and disturbances. Control architecture. The use of mechanical impedance as intended in the present research requires feedback of sensory information to the task control level. To accommodate this and other requirements of flexible manipulation, a real-time open-architecture control system (ROACS) is designed and developed in this thesis. The control system has a hierarchical structure with the capability of multi-mode control. A systematic method is developed for intelligent task control, where tasks may be represented in a descriptive manner with unknown task variables which may be determined and assigned during operation.

This thesis presents a new way of choosing design variables to tune the capabilities of a robot to the needs of an application. The associated proposals are demonstrated through the design of a haptic interface. It is argued that isotropy over a given workspace is a good measure of design quality for many high performance applications. A new measure of isotropy, the Global Isotropy Index or GII, is presented which is computed from the singular values of a design matrix. To ensure that the singular values are meaningful, a technique is presented which normalizes and scales the design matrix. The technique removes all physical units from the design matrix and scales it to accommodate an application-dependent performance specification and non-homogeneous actuator capabilities. An algorithm has also been developed that solves for the design parameters that result in the optimum GII. It is so efficient that it can be used to compare the relative isotropics of different robot configurations. Performance specifications for a haptic interface are taken from the literature and are augmented by two biomechanical studies. The values obtained are used by the proposed design procedure to select the best of three robots to be used as a haptic pen. The preferred candidate is a novel hybrid design that uses two 3- DOF pantographs to position the ends of a pen shaped end-effector. A prototype with passive roll about the pen axis is built and controlled to simulate three virtual environments including a virtual pencil, a virtual scalpel and a virtual excavator. Its performance characteristics are measured and are used to draw conclusions about the effectiveness of the design procedure. Finally, a further performance improvement is sought via redundant actuation. It is shown that the motion range and force capabilities of a coarse-stage robot can be combined with the precision and high-acceleration of a fine-stage robot by connecting them in series and joining their end-effectors by a flexible coupling. A coarse-fine system such as this is expected to narrow the gap between achievable and ideal haptic interface performance.","url":"https://doi.org/10.14288/1.0065296","authors":["Stocco, Leo J."],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0065296","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14288/1.0088569","name":"Smooth time optimal trajectory planning for industrial manipulators","source":"datacite","abstract":"This work proposes and demonstrates a strategy for planning smooth path-constrained time-optimal trajectories for manipulators. Such trajectories are obtained by limiting the actuator jerks required by the planned motion. Existing planning strategies incorporate the smoothness requirement either as smoothness of the actuator torques or as smoothness of the joint trajectories. The smoothness requirement is desirable for reducing strain on robot actuators while still requiring low cycle times. In this work, the trajectory smoothness is defined in the phase plane and the planning observes the limits on the actuator jerks. The solution proposed for determining the optimal trajectories consists of approximating the time optimal control problem by a nonlinear parameter optimization problem which is solved using the flexible tolerance method. It is shown that the approximate solution converges to the time optimal motion when the actuator jerks become very high. A number of simulations are performed to demonstrate the proposed strategy. These simulations show that actuator jerk limits have a negative impact on robot motion time, but they do not give any indication about robot trajectory feasibility. This aspect is studied through further simulations and experiments on an industrial robot. The results of this work show that the tracking accuracy is directly related to the actuator jerk limits. Therefore, it is necessary to impose such limits when planning feasible optimal trajectories. Finally, the performance of the smooth time optimal motion is compared to the performance of both the non-jerk limited optimal trajectory, as well as a smooth quintic trajectory. For similar actuator jerks and controller effort, the smooth path-constrained time-optimal trajectory results in a significantly shorter motion time with nearly the same tracking accuracy as a quintic polynomial. Based on the results in this work, actuator jerk limits are shown to provide an improved method of achieving a compromise between high tracking accuracy, smooth joint behaviour, and optimal motion time.","url":"https://doi.org/10.14288/1.0088569","authors":["Constantinescu, Daniela"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0088569","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14288/1.0087230","name":"Hybrid constraint space position/force control","source":"datacite","abstract":"This thesis documents the conceptual development of the author's contribution, the hybrid constraint space position/force controller for robotic manipulator control in constrained environments. This method is built upon a constraint space dynamic model, where the model parameters are displacement along the constraint trajectory and normal force between the manipulator end-effector and environment. This dynamic model is constructed by transforming conventional joint space manipulator dynamics into their constraint space equivalents through the application of mapping functions, which relate differential displacements and velocities in the constraint space coordinate system to the joint space coordinate system. Conventional PD controllers may then be applied to the simplified dynamic structure of the constraint space equations of motion, in order to produce a vector of manipulator joint torques which will satisfy both position and force requirements along the environmental constraint. Actuator constraints and momentum compensating techniques are also used to ensure that the position and force control problems are completely decoupled from one another. This modelling technique is then applied to the control problem for a two degree of freedom prismatic robot as an illustrative example. Simulation of this specific controller is carried out with respect to three different constraint surfaces, a planar, a concave circular and a convex circular environment. The results of these simulations show that the hybrid constraint space controller provides excellent position and force trajectory tracking for the planar case study.

Application of adaptive control to the robot is intended to tolerate these uncertainties and disturbances by letting the robot system learn and improve its performance as it operates. Usually, adaptive control algorithms assume that the control torque can be generated as desired. Since most of industrial robots are actuated by electrical DC motors, this assumption neglects actuator dynamics. In fact, the behavior of the actuators (DC motors) is governed by a third order differential equation, and sometimes the actuator dynamics will dominate the robot dynamics. Very few experiments have been reported on the adaptive control of robots incorporating actuator dynamics. Development, stability analysis and implementation of an adaptive control scheme that incorporates actuator dynamics is the core of this thesis research. To evaluate adaptive control and to compare its performance with other control schemes through real-time implementation, a robot testbed is developed by retrofitting an industrial robot with a custom-built controller. The testbed features an open hardware architecture, high computational capacity and good software programmability. The development of the testbed is also an essential part of the thesis research. The adaptive control scheme incorporating actuator dynamics is implemented on this testbed. The effects of the actuator dynamics are studied. Experiments show that the performance of the robot, with the adaptive control scheme, is significantly improved when compensated for the actuator dynamics. The comparison between the proposed control scheme and the conven tional joint PD controller shows that application of adaptive control to an industrial robot can significantly improve the performance of the robot with minimal extra cost.","url":"https://doi.org/10.14288/1.0081033","authors":["Zhou, Yuchen"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0081033","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14288/1.0098595","name":"Kinematic, force and dexterity analyses of planar robotic grasping","source":"datacite","abstract":"The grasping of an object or workpiece is an important step of robotic manipulation and is the main function of a robot hand. This has been a subject of considerable research. Robotic hands that can conform to the shape of a workpiece can provide efficient and stable handling, and furthermore, through suitable sensors, can serve as means for extracting information regarding the workpiece. But, for reasons of cost, size and weight, conformability of a robotic hand should be realized with the least possible number of actuators. In this study, a planar robotic gripper, suitable for the grasping and handling of a variety of objects, is designed, analysed, constructed and tested. The design has two fingers, four links, and two actuators, but can be directly extended to more links while keeping the number of actuators unchanged. This robotic end effector exhibits two distinctive features. First, it utilizes fewer number of actuators than it has degrees of freedom, thus providing quantifiable savings in weight, size, complexity and cost. Second, it is capable of conforming to different shapes and sizes of object through autonomous, sequential switching of the actuator drives between links. An analysis of the mechanics of the grasping process using a hand of this type is carried out, and simulated results are compared to the experimental results. Close agreement is exhibited in these comparisons. The analysis is extended to a six degree-of-freedom gripper, and to grippers having simultaneous, rather than sequential, link motion. In the final part of the study, a new method for the measurement of dexterity in grasping is proposed, based on the results obtained from the analyses and simulations. Accordingly, a robotic hand of the types analysed can be assigned a Grasping Dexterity value, defined as a measure of the ability of the hand to achieve successful grasps under a variety of situations in the shortest possible time.","url":"https://doi.org/10.14288/1.0098595","authors":["Saliba, Michael A."],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2010","doi":"10.14288/1.0098595","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.5281/zenodo.20051041","name":"Towards a Physical AI Safety Certification Framework: A Synthesis and Proposal","source":"datacite","abstract":"The deployment of artificial intelligence in physical systems — robots, autonomous vehicles, surgical platforms, and other actuator-driven machines — has outpaced the safety standards meant to govern it.

Palpation is a fundamental part of clinical training for physical examination. However, the learning approach remains a problem after centuries of modern medical development. A novel perspective to view this complex behaviour based on embodied physical intelligence pointed out that the learning of the technique ultimately relies on the training tasks and associated feedback. This opens up a new way to train medical practitioners with a quantitative archetype through soft robotic approaches. Pneumatic-based soft robots with elastomeric material have the advantages of high-compliance, easy-for-control, and flexible-in-design. More importantly, the inherent soft sensing with the driving fluid shows promising sensitivity and reliability for human-robot interaction in palpation training. Such an actuation/sensing approach was first employed in the design of a sensorized abdominal phantom with a controllable liver for realistic tumour rendering. Positive granular jamming nodules are used for tumour simulation instead of nodules made of pure rubber membrane. The method introduces extra constraints to the actuator where the volume/pressure curve can be effectively flattened. Thus, the valid control region is extended. This thesis then explored the force and position sensing ability of the multi-nodule phantom with a machine-learning-based methodology. Reliable results are shown with a UR5 robot performing palpation with complex motion. Finally, two applications of palpation training simulators based on the soft robotic approach were proposed: A full-sized abdominal phantom for physical environment training and a portable haptic interface for VR based training. In summary, the findings from this thesis provide important notations for designing a pneumatic based soft robot with coupled actuation and sensing. In particular, such methodology shows great potential in developing medical simulators for high-fidelity haptic rendering that encapsulates tactile sensing.","url":"https://doi.org/10.25560/97872","authors":["He, Liang"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.25560/97872","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.25560/99151","name":"Deployable soft robotics for minimally invasive surgery","source":"datacite","abstract":"Several benefits have been brought about by using Minimally Invasive Surgery (MIS), including faster procedure times, reduction of patient pain, and reductions in complications intraoperatively and postoperatively. However, some new techniques in MIS for colon cancer are technically difficult to perform using currently available instruments. Robotic systems for treatment of cancer in the lower Gastrointestinal (GI) tract have not shown performance that has translated into regular adoption. This thesis describes the creation of soft parallel robots for MIS that provide a different approach to the devices in the literature. To the author’s knowledge, this is the first deployable, laser welded, soft, hybrid parallel robot designed for minimally invasive surgery. The field of soft robotics relies on soft materials for the construction of robotic devices and is a growing field of research. A keyword search of soft robotic devices for use in MIS was performed, revealing general trends in the current research. It was found that a majority of devices in research were of continuum type, were moulded with elastomeric materials, and were pneumatically actuated. The literature review helped to shape the manufacturing approach taken in this work, as it had been identified that few devices were low-profile, deployable, or could significantly change their volume when transitioning from an inactive to active state. A laser welding system was designed and built for this purpose, delivering a rapid, low-cost, and adaptable manufacturing method for low-profile, deployable structures and actuators. This thesis describes the first use of this manufacturing technique for creation of soft robotic devices for minimally invasive surgery. A deployable, bimanual, cable-driven parallel robot was manufactured using the laser welding system and showed maximum force exertion capabilities of 8.29 N. A programmatic design approach was used to design the structure of the robot, which highlights the ability to customise the design. The robot was used to successfully perform a procedure with similar steps to Endoscopic Submucosal Dissection (ESD) with an untrained, novice user. The estimated volume change from the undeployed to the deployed state of the robot was approximately 73%. Novel soft hydraulic actuators were designed for use with deployable soft robots and were tested in a variety of configurations, from one Degree Of Freedom (DOF) to three DOFs. This is the first time, to the author’s knowledge, that open loop position control, length estimation based on internal pressure, and collision detection have been demonstrated with this type of actuator. Open loop position control was demonstrated with the soft actuator, achieving RMSE values of 0.47 mm for a single actuator acting against gravity and 0.35 mm when used in an antagonistic configuration. The hysteresis values in each configuration were 0.71 mm and 0.51 mm respectively. The contraction of the soft actuators was estimated based on the internal pressure of the actuators. The RMSE between the estimated contraction and desired contraction was 0.98 mm when applied to the pressure data from the same configuration and 0.76 mm in the hybrid parallel configuration after a correctional offset was applied. The internal pressure in the actuators was used to demonstrate collision detection when the actuators were setup in a hybrid parallel mechanism. 100% of the simulated collisions were detected using a heuristic method that monitored changes in pressure over time and the angle at which the collisions were made could also be estimated. The RMSE between the estimated contact angle and the true angle at which contact was made was 8.22° over a 120° test range, and the method had an R-squared value of 0.95. Finally, a second deployable robot was manufactured that used three of the novel soft actuators to control its end effector.

Deux systèmes SMP complexes biodégradables à base de bio-composés ou de monomères synthétiques ont été synthétisés. Pour les SMPs de mémorises multiples, nous avons synthétisé une série de copolymères statistiques avec des groupes pendants d'acide cholique en utilisant une méthode de polymérisation radicalaire simple. Ces copolymères ont une température de transition vitreuse (Tg) réglable, selon le ratio de comonomères, qui montrent à la fois des effets mémoires à double et triple états (PME). Les rapports entre la fixité et la récupération de la mémoire de forme double ou triple peuvent être améliorés par l'incorporation d'un groupe cinnamate dans les copolymères afin de permettre la photo-réticulation du polymère. Les polymères réticulés présentent des rapports de récupération améliorés pour la mémoire de forme double et triple et présentent même des PME quadruples.

Des mouvements réversibles comme flexion-extension et enroulement-déroulement ont été observés pour le réseau de polymère. La TA de 2W-SMP sous conditions sans stress peut être facilement contrôlée en sélectionnant un ou deux prépolymères comme segments du réseau polymère. Le changement de l’élongation absolue des 2W-SMP est augmenté sous les conditions avec ou sans stress, mais le changement d’élongation relative est réduit avec l'augmentation de tension sous condition de stress.

Since their discovery they have become invaluable tools for imaging living systems and have been developed into precision instruments for measuring normally invisible events such as fluctuations in calcium ion concentration, protein-protein interactions (PPi), and even membrane voltage. More surprisingly, FPs have now been converted into optogenetic actuators capable of manipulating the biochemistry of the cell. There is substantial interest in improving both the diversity and quality of available FPs because of their great utility and potential. In this thesis, I describe my efforts to design better methods to easily improve FPs and I use these methods to create a variety of new FP variants. First, I explored the potential of developing FPs as tandem dimers. I used directed evolution to create a series of heterodimeric FPs called the vine Tomatoes (vTs). Specifically, I created green-green (GGvT), green-red (GRvT), and red-red (RRvT) heterodimers by genetically fusing two tightly dimerizing FP domains and then evolving as a pair. This allows the two monomers to differentiate, creating tandem heterodimers with advanced characteristics such as exceptionally high FRET efficiency in GRvT of 99%, and the brightest red fluorescent protein to date with RRvT at 120. Next I developed a robot-assisted screening system for photostability screening. This simplified screening process led to the development of Citrine2, a variant with 9-fold improvement in photostability relative to its precursor, mCitrine. I also observed that concentration plays a significant role in photostability, and I so I attempted to modify this property. With only five mutations, the concentration dependence of photostability switched from being an inverse relationship in mCitrine, to a direct relationship in Citrine2. From there I switched to developing new screening systems for photocleavable proteins. Several different screening systems based on bimolecular fluorescence complementation and FRET were developed to screen directly for the photoinduced dissociation of a photocleavable protein (PhoCl) developed in our lab. A second photocleavable protein called SplitOr was created from PSmOrange2. The goal was to develop a spectrally orthogonal photocleavable protein that could be photocleaved with wavelengths of light that do not cause PhoCl photocleavage. PSmOrange2 was circularly permuted and its fluorescence and photoconversion properties rescued, creating three new versions of SplitOr with photophysical characteristics that suggest photocleavage is occurring. Altogether, these projects have advanced the field of FP development. I created three research-ready FPs, RRvT, GRvT, and Citrine2; I developed and characterized a rapid, low cost, robot-assisted illumination system which will aid our lab and others in the development of photostable FP variants; I advanced our knowledge of photocleavable proteins by developing an evolution system for the photocleavable protein PhoCl; and finally I created an orthogonal photocleavable protein that may find use as an optogenetic actuator.","url":"https://doi.org/10.7939/r30r9mm0c","authors":["Wiens, Matthew D"],"tags":["Photophysics","Fluorescent protein","Protein engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2017","doi":"10.7939/r30r9mm0c","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.7939/r3g922","name":"Sliding-Mode Control of Pneumatic Actuators for Robots and Telerobots","source":"datacite","abstract":"For robotic systems that use pneumatic actuators with on/off solenoid valves, sliding-mode control laws for precise position control and low switching (open/close) activity of the valves are presented. A pneumatic actuator has two chambers with a total of four on/off solenoid valves. Thus, there are sixteen possible combinations for the valves' on/off positions. Only seven of these sixteen \"operating modes\" are considered both functional and unique. While previous work has focused on three-mode closed-loop control of such an actuator, this thesis extends the three-mode control to seven-mode control. This thesis also extends the application from the position control of a single robot to the bilateral control of a telerobot. We introduce and compare two novel seven-mode controllers for a pneumatic actuator. The first is a sliding-mode controller utilizing a switching function that is a function of the system states. The second is a sliding-mode, pulse-width-modulation (PWM) controller utilizing a time-averaged model of the open-loop system. Both controllers minimize the tracking error by employing the operating modes that have the necessary and sufficient amounts of drive energy and, thus, involve reduced switching activity while maintaining satisfactory tracking performance. The performance of the proposed control design is experimentally verified on a single pneumatic actuator. Also, the seven-mode position control is extended to force control to make seven-mode teleoperation control possible. Experimental verification on a pair of pneumatic actuators utilizing position-position based and force-position based teleoperation control to verify the validity of our theoretical results. Overall, it is found that leveraging the additional modes of operation leads to more efficient and smoother control in both the single-actuator and the dual-actuator teleoperated pneumatic systems.","url":"https://doi.org/10.7939/r3g922","authors":["Hodgson, Sean E"],"tags":["Pneumatic actuator","Sliding-mode control","Teleoperation","On/off solenoid valve"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2012","doi":"10.7939/r3g922","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.48550/arxiv.2604.25337","name":"Design and Modeling of a HASEL Actuator-Based Micro Parallel Robot","source":"datacite","abstract":"This paper presents the mechatronic design, dynamic modeling, and experimental validation of a three-degree-of-freedom (3-DOF) micro parallel robot featuring a prismatic-spherical (3PS) topology actuated by three Hydraulically Amplified Self-Healing Electrostatic (HASEL) actuators.

This design minimizes weight but couples both wings to a shared input motor, eliminating independent thrust control and preventing asymmetric maneuvers. This thesis investigates thrust regulation by modifying the effective length of the first radius link $R_1$ in the computational structure. Static experiments using FDM-printed $R_1$ links at three lengths (28.58, 29.33, and 30.08 mm) across 3,4, and 5 Hz flapping frequencies demonstrated that a 1.5 mm length increase produced a 37% increase in peak lift force and shifted peak force timing within the downstroke. An additional experiment using a string-actuated regulator mechanism was performed. Further actuation methods were evaluated: sub-gram micro-servo and piezoelectric slip-stick. After both the string-tension and micro-servo actuation methods failed due to structural member compliance and motor fragility respectively, a TULA-50 piezoelectric slip-stick actuator was selected. Multiple force-amplifying mechanisms were prototyped, resulting in a direct-drive variable-length mechanism. This final mechanism was demonstrated in a preliminary bench-top test, though insufficient force output prevented dynamic testing during flapping.

Existing techniques either fail to guarantee satisfaction at all times, or incur prohibitive computational costs. This paper presents RAYEN, a framework for imposing hard convex constraints on the output or latent variables of a neural network. RAYEN guarantees constraint satisfaction during both training and testing, for any input and any network weights. Unlike prior approaches, RAYEN avoids computationally expensive orthogonal projections, soft constraints, conservative approximations of the feasible set, and slow iterative corrections. RAYEN supports any combination of linear, convex quadratic, second-order cone (SOC), and linear matrix inequality (LMI) constraints, with negligible overhead compared to unconstrained networks. For instance, it imposes 1K quadratic constraints on a 1K-dimensional variable with only 8 ms of overhead compared to a network that does not enforce these constraints. An LMI constraint with 300x300 dense matrices on a 10K-dimensional variable can be guaranteed with only 12 ms additional overhead. When used in neural networks that approximate the solution of constrained trajectory optimization problems, RAYEN runs 20 to 7468 times faster than state-of-the-art algorithms, while guaranteeing constraint satisfaction at all times and achieving a near-optimal cost (&lt;1.5% optimality gap).

L’émergence de la robotique de terrain a introduit de nouveaux défis. Les robots de locomotion articulés, tels que les bipèdes et quadrupèdes, sont idéaux pour se déplacer dans des environnements complexes, mais leur conception reste difficile, notamment pour les contraintes de masse, d’efficacité et de transparence mécanique des actionneurs. Les systèmes portables d’assistance physique, comme les exosquelettes et les prothèses, partagent des défis similaires. La conception d’actionneurs pour la locomotion articulée implique de nombreux compromis. Les technologies actuelles, qu’il s’agisse d’actionneurs hydrauliques, électriques ou quasi passifs, doivent répondre à des exigences contradictoires de puissance, d’efficacité, de légèreté et de capacité d’interaction fine avec l’environnement. Chaque approche présente des limitations qui restreignent les performances globales des robots, comme au niveau de la force ou de la polyvalence. Pour dénouer cette problématique, cette thèse par articles aborde un nouveau paradigme de conception d’actionneurs pour la robotique : l’hydrostatique reconfigurable (ou hybride). Plus spécifiquement, on répond à la question suivante : quel est le potentiel d’augmentation des performances des robots de locomotion articulée avec l’hydrostatique reconfigurable ? Cette question est traitée par des volets conceptuels, analytiques et expérimentaux, et ce, dans un contexte de robots marcheurs et de systèmes d’assistance physique. Douze principes et variantes d’actionneurs hybrides hydrostatiques sont proposés et analysés, notamment un actionneur à ratio variable, une compensation passive et ajustable du poids et de la charge utile transportée, et le partage du même actionneur pour les jambes gauches et droites. Une modélisation par lois d’échelle et des études de cas comparent chaque concept hybride avec un actionneur de référence, et ce, sur le plan de la masse, de l’efficacité et de la transparence mécanique. Un prototype permet de valider la faisabilité expérimentale des concepts les plus prometteurs et met en évidence certains défis à contourner. Bien que les concepts hydrostatiques nécessitent l’ajout de composants supplémentaires, il est démontré qu’à masse égale d’actionnement, le concept à ratio variable et la compensation passive et ajustable permettent d’améliorer considérablement la performance des robots de locomotion articulée. Par exemple, en intégrant une compensation passive ajustable, un bipède commercial pourrait consommer quatre fois moins d’énergie, doubler la charge utile transportée et diminuer l’inertie réfléchie de 63%. De plus, l’hydrostatique reconfigurable s’avère utile pour augmenter la polyvalence de concepts hybrides. Pour le partage hydrostatique, par exemple, l’ajout d’une valve permet non seulement d’assister les mouvements alternés (marcher, courir), mais aussi les mouvements combinés (soulever une charge, sauter) des jambes gauches et droites, ce qui n’est jamais le cas dans les systèmes d’assistance physique sous-actionnés.","url":"https://doi.org/10.71892/11143/1052","authors":["Denis, Jeff"],"tags":["Robotique","Locomotion articulée","Actionneur","Hybride","Hydraulique","Quasi passif","Sous-actionné","Lois d’échelle"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.71892/11143/1052","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.48550/arxiv.2604.10351","name":"Trajectory-based actuator identification via differentiable simulation","source":"datacite","abstract":"Accurate actuation models are critical for bridging the gap between simulation and real robot behavior, yet obtaining high-fidelity actuator dynamics typically requires dedicated test stands and torque sensing. We present a trajectory-based actuator identification method that uses differentiable simulation to fit system-level actuator models from encoder motion alone. Identification is posed as a trajectory-matching problem: given commanded joint positions and measured joint angles and velocities, we optimize actuator and simulator parameters by backpropagating through the simulator, without torque sensors, current/voltage measurements, or access to embedded motor-control internals. The framework supports multiple model classes, ranging from compact structured parameterizations to neural actuator mappings, within a unified optimization pipeline. On held-out real-robot trajectories for a high-gear-ratio actuator with an embedded PD controller, the proposed torque-sensor-free identification achieves much tighter trajectory alignment than a supervised stand-trained baseline dominated by steady-state data, reducing mean absolute position error from 14.20 mrad to as low as 7.54 mrad (1.88 times).

We propose a framework that avoids sensors and computation entirely, instead relying on the human visual system's assumption of convexity to produce perceptual gaze-following between a robot and its viewer. Specifically, we motivate sub-dollar cardboard robot design that directly implements the brain's own gaze computation pipeline in reverse, making the viewer's perceptual system the robot's \"actuator\", with no sensors, no power, and no privacy concerns. We ground this framework in three converging lines of theoretical and empirical neuroscience evidence. Namely, the distributed face processing network that computes gaze direction via the superior temporal sulcus, the high-precision convexity prior that causes the brain to perceive concave faces as convex, and the predictive processing hierarchy in which top-down face knowledge overrides bottom-up depth signals. These mechanisms explain why a concave eye socket with a painted pupil produces the perception of mutual gaze from any viewing angle. We derive design constraints from perceptual science, present a sub-dollar open-template robot with parameterized interchangeable eye inserts, and identify boundary conditions (developmental, clinical, and geometric) that predict where the framework will succeed and where it will fail.

Such systems provide body and limbs with the functionality that is used to efficiently absorb external shocks and exchange of mechanical energy, e.g. kinetic and potential energy, to exploit natural dynamics during locomotion. In biology, it has been found that animals and humans adjust their limb stiffness to accommodate for different speeds, gaits, and terrains. On contrary, in the field of legged robots, little has been known about how to control leg stiffness to efficiently adapt to changes of speed, terrain, and gait or stride frequency at which the leg oscillates. Therefore, this thesis aims at contributing to the primary understanding of the topic. Until today, mechanical springs with fixed spring constants are still widely used as energy saving mechanisms and shock absorbers for legged robots. However, the compliance of those springs is not adjustable and manual assembly is required to make a robot leg stiffer or more compliant. Motivated by this fact, we present a systematic development and evaluation of a new variable compliance/stiffness actuator, named MESTRAN (MEchanism to vary Stiffness via Transmission ANgle) in this thesis. This actuator serves as a key tool to investigate energy efficient locomotion at various stride frequencies and on surfaces with different stiffness. MESTRAN can dynamically alter joint stiffness in an unlimited range. It is also capable of maintaining the stiffness without requiring energy and offering different types of compliance, e.g. linear, quadratic, or exponential. In this thesis, we first designed and constructed an adjustable stiffness leg based on the MESTRAN design. We then validated the design by conducting a series of experiments by using the first leg prototype. Second, in order to investigate hopping locomotion with variable stiffness capability, we designed a single-legged robot, named L-MESTRAN (Linear-MESTRAN), which is an advanced version of the MESTRAN leg. We systematically analysed and demonstrated the mechanical performance of the legged robot using the simulations and a number of real-world hopping experiments. As a result, we found that a proper adjustment of leg stiffness can improve the hopping energy efficiency of the robot at various stride frequencies. Third, this finding was also investigated on surfaces with different stiffness by using the L-MESTRAN robot. The simulation and experimental results indicated that, for a particular stride frequency (3 - 6 [Hz]), the adjustment of the knee stiffness can accommodate for changes in surface compliance, resulting in an improvement of the energy efficiency of hopping.","url":"https://doi.org/10.5167/uzh-164391","authors":["Vu, Hung Quy"],"tags":["620 Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2013","doi":"10.5167/uzh-164391","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.5167/uzh-257364","name":"User-Conditioned Neural Control Policies for Mobile Robotics","source":"datacite","abstract":"Recently, learning-based controllers have been shown to push mobile robotic systems to their limits and provide the robustness needed for many real-world applications. However, only classical optimization-based control frameworks offer the inherent flexibility to be dynamically adjusted during execution by, for example, setting target speeds or actuator limits. We present a framework to overcome this shortcoming of neural controllers by conditioning them on an auxiliary input. This advance is enabled by including a feature-wise linear modulation layer (FiLM). We use model-free reinforcement-learning to train quadrotor control policies for the task of navigating through a sequence of waypoints in minimum time. By conditioning the policy on the maximum available thrust or the viewing direction relative to the next waypoint, a user can regulate the aggressiveness of the quadrotor's flight during deployment. We demonstrate in simulation and in real-world experiments that a single control policy can achieve close to time-optimal flight performance across the entire performance envelope of the robot, reaching up to 60 km/h and 4.5 g in acceleration. The ability to guide a learned controller during task execution has implications beyond agile quadrotor flight, as conditioning the control policy on human intent helps safely bringing learning based systems out of the well-defined laboratory environment into the wild.","url":"https://doi.org/10.5167/uzh-257364","authors":["Bauersfeld, Leonard","Kaufmann, Elia","Scaramuzza, Davide"],"tags":["000 Computer science, knowledge &amp; systems"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.5167/uzh-257364","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.48550/arxiv.2603.28542","name":"Feel Robot Feels: Tactile Feedback Array Glove for Dexterous Manipulation","source":"datacite","abstract":"Teleoperation is a key approach for collecting high-quality, physically consistent demonstrations for robotic manipulation.

To address these challenges, we present TAG, a low-cost glove system that integrates precise hand motion capture with high-resolution tactile feedback, enabling effective tactile-in-the-loop dexterous teleoperation.

A safe robot arm can be achieved using either an active or passive compliance method. A passive compliance system composed of purely mechanical elements often provides faster and more reliable responses to dynamic collision than an active system involving sensors and actuators. Since positioning accuracy and collision safety of a robot arm are equally important, a robot arm should have very low stiffness when subjected to a collision force capable of causing human injury. Otherwise, it should maintain a very high stiffness. To implement these requirements, a novel safe joint mechanism (SJM-IV) consisting of a CAM, rotational links with rollers, and torsion springs is proposed. The SJM-IV has the advantage of nonlinear stiffness, which can be achieved only with passive mechanical elements. Various analyses and experiments on static and dynamic collisions show high stiffness of the SJM-IV against an external torque less than a predetermined threshold torque, with an abrupt drop in stiffness when the external torque exceeds this threshold. The safe joint mechanism enables a robot manipulator to guarantee positioning accuracy and collision safety, and which is simple to install between an actuator and a robot link without a significant change in the robot’s design.","url":"https://doi.org/10.6084/m9.figshare.12672014","authors":["Belharet, Adel","Song, Jae-Bok"],"tags":["Manufacturing robotics","Mechanical engineering not elsewhere classified"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.6084/m9.figshare.12672014","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.5281/zenodo.19060106","name":"A Robust Control Method for Robotic Hands Based on Brain Topographic Mapping and Phantom Limb Mechanism","source":"datacite","abstract":"This paper presents a robust control method for robotic hands inspired by brain topographic mapping and phantom limb mechanisms.

Training these models relies solely on controlled decay trajectories of the actuator-augmented state, thereby removing the additional actuation-calibration step commonly needed by prior SSM-for-control methods. We learn a compact caSSM model for a tendon-driven trunk robot, enabling real-time control and reducing open-loop prediction error by 40% compared to existing methods.

However, policies trained in simulation often fail to transfer to real-world robots due to unrealistic assumptions such as infinite actuator bandwidth and the absence of torque limits. These conditions allow policies to rely on abrupt, high-frequency torque changes, which are infeasible for real actuators with finite bandwidth. Traditional methods address this issue by penalizing aggressive motions through regularization rewards, such as joint velocities, accelerations, and energy consumption, but they require extensive hyperparameter tuning. Alternatively, Lipschitz-Constrained Policies (LCP) enforce finite bandwidth action control by penalizing policy gradients, but their reliance on gradient calculations introduces significant GPU memory overhead. To overcome this limitation, this work proposes Spectral Normalization (SN) as an efficient replacement for enforcing Lipschitz continuity. By constraining the spectral norm of network weights, SN effectively limits high-frequency policy fluctuations while significantly reducing GPU memory usage. Experimental evaluations in both simulation and real-world humanoid robot show that SN achieves performance comparable to gradient penalty methods while enabling more efficient parallel training.","url":"https://doi.org/10.48550/arxiv.2504.08246","authors":["Shin, Jaeyong","Cha, Woohyun","Kim, Donghyeon","Cha, Junhyeok","Park, Jaeheung"],"tags":["Robotics (cs.RO)","Machine Learning (cs.LG)","Systems and Control (eess.SY)","FOS: Computer and information sciences","FOS: Computer and information sciences","FOS: Electrical engineering, electronic engineering, information engineering","FOS: Electrical engineering, electronic engineering, information engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2504.08246","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.48550/arxiv.2410.04304","name":"Robotics Meets Software Engineering: A First Look at the Robotics Discussions on Stackoverflow","source":"datacite","abstract":"Robots can greatly enhance human capabilities, yet their development presents a range of challenges.

Our findings indicate that the small size of the robotics community limits the visibility of these questions, resulting in fewer responses. While the number of robotics questions has been steadily increasing, they remain less popular than the average question and answer on StackOverflow. This underscores the importance of research that focuses on the challenges faced by robotics practitioners. Consequently, we conducted a thematic analysis of the 500 robotics questions to uncover common inquiry patterns. We identified 11 major themes, with questions about robot movement being the most frequent. Our analysis of yearly trends revealed that certain themes, such as Specifications, were prominent from 2009 to 2014 but have since diminished in relevance. In contrast, themes like Moving, Actuator, and Remote have consistently dominated discussions over the years. These findings suggest that challenges in robotics may vary over time. Notably, the majority of robotics questions are framed as How questions, rather than Why or What questions, revealing the lack of enough resources for the practitioners.

We present UniDex, a robot foundation suite that couples a large-scale robot-centric dataset with a unified vision-language-action (VLA) policy and a practical human-data capture setup for universal dexterous hand control. First, we construct UniDex-Dataset, a robot-centric dataset over 50K trajectories across eight dexterous hands (6--24 DoFs), derived from egocentric human video datasets. To transform human data into robot-executable trajectories, we employ a human-in-the-loop retargeting procedure to align fingertip trajectories while preserving plausible hand-object contacts, and we operate on explicit 3D pointclouds with human hands masked to narrow kinematic and visual gaps. Second, we introduce the Function-Actuator-Aligned Space (FAAS), a unified action space that maps functionally similar actuators to shared coordinates, enabling cross-hand transfer. Leveraging FAAS as the action parameterization, we train UniDex-VLA, a 3D VLA policy pretrained on UniDex-Dataset and finetuned with task demonstrations. In addition, we build UniDex-Cap, a simple portable capture setup that records synchronized RGB-D streams and human hand poses and converts them into robot-executable trajectories to enable human-robot data co-training that reduces reliance on costly robot demonstrations. On challenging tool-use tasks across two different hands, UniDex-VLA achieves 81% average task progress and outperforms prior VLA baselines by a large margin, while exhibiting strong spatial, object, and zero-shot cross-hand generalization. Together, UniDex-Dataset, UniDex-VLA, and UniDex-Cap provide a scalable foundation suite for universal dexterous manipulation.","url":"https://doi.org/10.48550/arxiv.2603.22264","authors":["Zhang, Gu","Xu, Qicheng","Zhang, Haozhe","Ma, Jianhan","He, Long","Bao, Yiming","Ping, Zeyu","Yuan, Zhecheng","Lu, Chenhao","Yuan, Chengbo","Liang, Tianhai","Tian, Xiaoyu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2603.22264","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:16.227Z"},{"id":"doi:10.48550/arxiv.2603.19794","name":"Generalized Task-Driven Design of Soft Robots via Reduced-Order FEM-based Surrogate Modeling","source":"datacite","abstract":"Task-driven design of soft robots requires models that are physically accurate and computationally efficient, while remaining transferable across actuator designs and task scenarios. However, existing modeling approaches typically face a fundamental trade-off between physical fidelity and computational efficiency, which limits model reuse across design and task variations and constrains scalable task-driven optimization. This paper presents a unified reduced-order finite element method (FEM)-based surrogate modeling pipeline for generalized task-driven soft robot design. High-fidelity FEM simulations characterize actuator behavior at the modular level, from which compact surrogate joint models are constructed for evaluation within a pseudo-rigid body model (PRBM). A meta-model maps actuator design parameters to surrogate representations, enabling rapid instantiation across a parameterized actuator family. The resulting models are embedded into a PRBM-based simulation environment, supporting task-level simulation and optimization under realistic physical constraints. The proposed pipeline is validated through sim-to-real transfer across multiple actuator types, including bellow-type pneumatic actuators and a tendon-driven soft finger, as well as two task-driven design studies: soft gripper co-design via Reinforcement Learning (RL) and 3D actuator shape matching via evolutionary optimization.

Designing soft robots that leverage this interaction remains a significant challenge, particularly when morphology and control require simultaneous optimization. A significant obstacle in this co-design process is that morphological evolution can disrupt learned control strategies, making it difficult to reuse or adapt existing knowledge. We address this by develop a Graph Neural Network-based approach for the co-design of morphology and controller. Each robot is represented as a graph, with a graph attention network (GAT) encoding node features and a pooled representation passed through a multilayer perceptron (MLP) head to produce actuator commands or value estimates. During evolution, inheritance follows a topology-consistent mapping: shared GAT layers are reused, MLP hidden layers are transferred intact, matched actuator outputs are copied, and unmatched ones are randomly initialized and fine-tuned. This morphology-aware policy class lets the controller adapt when the body mutates. On the benchmark, our GAT-based approach achieves higher final fitness and stronger adaptability to morphological variations compared to traditional MLP-only co-design methods. These results indicate that graph-structured policies provide a more effective interface between evolving morphologies and control for embodied intelligence.","url":"https://doi.org/10.48550/arxiv.2603.19582","authors":["Wang, Jianqiang","Pan, Shuaiqun","Serra-Gomez, Alvaro","Wei, Xiaohan","Xie, Yue"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2603.19582","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.5281/zenodo.18937819","name":"Fault BF Dataset","source":"datacite","abstract":"Dataset for Intermittent Fault and Progressive Actuator Degradation: Features are extracted exteroceptively and continuously by each observer on the observed robot.

This enables a continuous and stable reconfiguration process that is independent of the surrounding medium, allowing the system to reliably form various configurations in diverse environments. To leverage the unique kinematics of RhoMorph, we introduce morphpivoting, a novel motion primitive for reconfiguration that differs from advanced MSRR systems, and propose a strategy for its continuous execution. Finally, a series of physical experiments validate the module's stable reconfiguration ability, as well as its positional and docking accuracy.","url":"https://doi.org/10.48550/arxiv.2601.19529","authors":["Gu, Jie","Sun, Yirui","Xia, Zhihao","Lam, Tin Lun","Tian, Chunxu","Zhang, Dan"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2601.19529","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.4121/16943254.v1","name":"Soft Gripper AR Framework","source":"datacite","abstract":"Open-source framework for real-time three-dimensional reconstruction of soft robots in eXtended Reality (Augmented and Virtual Reality)..Contains ROS code for interfacing with the actuator, together with unity scripts that allow for live animation data to be visualized in AR, as part of research into integrating XR technologies in the soft robot domain.","url":"https://doi.org/10.4121/16943254.v1","authors":["Andrade Borges, Elvis","Rieder, Jonas"],"tags":["Computer Software and Services","Computer Software","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.4121/16943254.v1","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.4121/16943254.v2","name":"Soft Gripper AR Framework","source":"datacite","abstract":"Open-source framework for real-time three-dimensional reconstruction of soft robots in eXtended Reality (Augmented and Virtual Reality)..Contains ROS code for interfacing with the actuator, together with unity scripts that allow for live animation data to be visualized in AR, as part of research into integrating XR technologies in the soft robot domain.","url":"https://doi.org/10.4121/16943254.v2","authors":["Andrade Borges, Elvis","Rieder, Jonas"],"tags":["Computer Software and Services","Computer Software","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.4121/16943254.v2","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.4121/16943254","name":"Soft Gripper AR Framework","source":"datacite","abstract":"Open-source framework for real-time three-dimensional reconstruction of soft robots in eXtended Reality (Augmented and Virtual Reality)..Contains ROS code for interfacing with the actuator, together with unity scripts that allow for live animation data to be visualized in AR, as part of research into integrating XR technologies in the soft robot domain.","url":"https://doi.org/10.4121/16943254","authors":["Andrade Borges, Elvis","Rieder, Jonas"],"tags":["Computer Software and Services","Computer Software","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.4121/16943254","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14279/depositonce-8947","name":"A Novel Framework for a Systematic Integration of Pneumatic-Muscle-Actuator-Driven Joints into Robotic Systems Via a Torque Control Interface","source":"datacite","abstract":"In this paper, two different torque control approaches for PMA-driven (PMA = Pneumatic muscle actuator) revolute joints are presented and tested. In previous work controllers for PMA-driven robots are typically customized for the use on a specific robotic system. In contrast, the proposed controllers define a general control interface for every robot that is actuated by PMA-driven joints. It will be shown that controlling the torque of a PMA-driven joint enables the use of standard robotic motion control frameworks, because the torque represents the natural input of the robotic equation of motion. Therefore, both proposed torque control approaches are interconnecting PMAs and their challenging characteristics on the one hand and “conventional” motion control strategies for robots on the other hand. After a detailed discussion of two different torque control approaches, we show that a torque controller handles all characteristics and dynamics of a PMA-driven joint internally, which implies that only its bandwidth and its static torque characteristic must be taken into account for the design of the outer motion control loop. This feature simplifies the integration of PMA-driven joints in robotic systems enormously, as will be demonstrated by a design of a cascade-structured, flatness-based motion controller for an exemplary robot with one degree of freedom.","url":"https://doi.org/10.14279/depositonce-8947","authors":["Martens, Mirco","Seel, Thomas","Zawatzki, Johannes","Boblan, Ivo"],"tags":["600 Technik, Technologie","pneumatic muscle actuator","pneumatic artificial muscle","pneumatic-muscle-actuator-driven joint","pneumatic system","pneumatic robot","PMA","PAM"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.14279/depositonce-8947","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14279/depositonce-9364","name":"Modeling the Static Force of a Festo Pneumatic Muscle Actuator: A New Approach and a Comparison to Existing Models","source":"datacite","abstract":"In this paper, a new approach for modeling the static force characteristic of Festo pneumatic muscle actuators (PMAs) will be presented.

The approach we take is to fundamentally reconsider the basic motivation and goals for grasping that steer hand design. We consider grasping as the result of reliable and robust patterns of interaction between hand, object and environment which are mechanically opaque to the robot. This motivates the investigation of a new type of robotic hands, pneumatic soft hands. These hands enable the robot to collide with objects safely, maintain contact under disturbance, and provide many places of contact for a robust grasp. At the same time they intend to lower requirements on control and perception compared to fully actuated hands. Due to the fundamental change in perspective compared to the classical, mechanics-centric view in grasping, I believe we will ultimately have to reconsider all aspects of a robot system to use soft hands effectively. We call this alternative view the Soft Manipulation paradigm. In this thesis we propose a list of defining principles for Soft Manipulation and focus on the ramifications for hand hardware, but we also consider the adjacent domains of hand control and grasping strategies. Research on soft hands is complicated by the fact that the technology and body of knowledge for building soft hands only is emerging right now. The thesis contributes the groundwork for soft hand research by developing a coherent and comprehensive set of tools to rapidly prototype pneumatic soft hands. This toolkit is built around a versatile and easy to prototype actuator design named PneuFlex. The thesis will cover all aspects of prototyping such as designing mechanical properties, manufacturing actuators, assembling them into hands, and controlling them without interfering in their compliance. We also propose and validate a fast and stable dynamic simulation model for the simulation of pneumatic soft hands which for the first time makes interactive and automated design of soft hands feasible. The thesis also explores the properties and capabilities of pneumatic soft hands in a series of grasping experiments with the help of two artifacts, the RBO Hand 1 and RBO Hand 2. We investigate their shape adaptability, their grasp dexterity, and their suitability for implementing grasping strategies that exploit environment constraints to motion for robust execution. We will see that soft hands built with technology developed in the first part of the thesis provide a solid foundation for further research on Soft Manipulation.","url":"https://doi.org/10.14279/depositonce-6063","authors":["Deimel, Raphael"],"tags":["620 Ingenieurwissenschaften und zugeordnete Tätigkeiten","robotics","soft hands","grasping","PneuFlex","soft continuum actuator","simulation","construction"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2017","doi":"10.14279/depositonce-6063","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14279/depositonce-6802","name":"The Working Posture Controller - automated adaptation of the workpiece pose to enable a neutral working posture","source":"datacite","abstract":"The human worker plays a vital role on the production line. Although modern automation technology has succeeded in replacing much of the workforce in factories, there are scenarios where full automation cannot be realised. For example, enterprises offering a broad portfolio of varying products can often not afford the reconfiguration costs of frequently changing manufacturing facilities. Moreover, there are still tasks, such as dealing with highly flexible workpieces, which cannot be effectively automatised. Experienced human workers, in contrast to machinery, are able to adapt to new tasks in a short time and possess cognitive and sensorimotor skills that, at the present time, cannot be imitated by machines. However, maintaining the health of the workforce is a challenge. Work-related musculoskeletal disorders (WMSDs) are the dominant reason for worker absenteeism, leading to large financial losses for states and companies. One fundamental risk factor for these disorders is work that requires awkward postures. For this reason, extensive research has been conducted into preventing awkward postures in the workplace. The solutions proposed thus far have achieved a significant improvement of the situation. However, implementing the most effectual solutions is labour-intensive and impairs the flexibility of the production line. In brief, robust solutions must be individualised to the specific task and workplace. Although there are approaches that are able to facilitate automatically adapting to new tasks, they are far less effective. In the present thesis, this dilemma is referred to as the ''effectiveness-flexibility trade-off''. This thesis strives to bridge this trade-off. Herein, the Working Posture Controller (WPC), a novel type of equipment that imitates the measures performed by workplace designers, was proposed. The WPC automatically monitors the worker's posture when performing a task at hand. In the case of an ergonomically unfavourable situation, the device proposes a re-adjustment of the workplace layout, enabling the worker to perform the same task while maintaining an ergonomically superior posture. The actual re-adjustment can then be realised by an actuator. Here, system concepts and algorithms to produce such a piece of equipment were developed. In detail, the proposed methods can perform posture assessments automatically using a depth camera and optimise posture through workplace layout adjustments. As the computation time needed for these components is just a few seconds, the system is capable of reacting immediately. The system components were evaluated in isolation as well as in a demonstrator scenario. The experiments revealed that the automated posture assessment results were comparable to a manual assessment. Furthermore, the automated posture optimisation was seemingly able to transform most postures with high physical load into low-load postures. Apart from their role with the WPC, the fundamental algorithms developed in this thesis can also be applied in other applications in the field of ergonomics and human-robot collaboration.","url":"https://doi.org/10.14279/depositonce-6802","authors":["Nguyen, The Duy"],"tags":["006 Spezielle Computerverfahren","620 Ingenieurwissenschaften und zugeordnete Tätigkeiten","computer vision","ergonomics","human-centred automation","human-machine interaction","maschinelles Sehen","Ergonomie"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.14279/depositonce-6802","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.14279/depositonce-14760","name":"Control of pneumatic-muscle-actuator-driven joints in robotic applications","source":"datacite","abstract":"Many robotic systems can be improved by novel, lightweight, and elastic actuators. While smaller weight reduces the kinetic energy of the system, elasticity offers the potential to absorb and release potential energy. Thus, the safety of the robot can be increased only by the use of light and elastic actuators, so that there is less energy transmitted in the case of collisions and damages or injuries would therefore be milder. In addition, stored potential energy can be used to perform motion sequences with increased energy efficiency. One type of these actuators are pneumatic-muscle-actuator-driven joints – a combination of two pneumatic-muscle-actuators (PMAs) and a pulley –, as they provide a high torque-to-weight ratio with an adjustable stiffness. Analogously to biological muscle pairs, PMA-driven joints also yield the opportunity to change their stiffness via co-contraction and, due to this, to adapt to the demands of varying tasks. The investigation of the properties of PMA-driven joints and their integration into robotic systems form the core of this dissertation. Since PMA-driven joints consist essentially of two pneumatic muscle actuators, there is an initial chapter devoted to force modeling of pneumatic muscles in addition to the study of PMA-driven joints. It compares existing force models based on a new quality measure and introduces a new model with higher accuracy. Although there were numerous publications on robots with PMA-driven joints prior to this work, little attention has been given to their properties in general. It remains mostly unclear why a specific robot with PMA-driven joints is able to fulfill its task and how this depends on the characteristics of the chosen PMA-driven joints. Motivated by this, the present thesis provides a general discussion on the characteristics of PMA-driven joints, like their static torque range, their joint stiffness and the bandwidth of their joint torque. All results are discussed with the goal to drive a robotic system with PMA-driven joints and all essential information will be provided within this thesis. With this information at hand it will be demonstrated how to use this information to drive three different robotic systems with PMA-driven joints, successfully. Unlike most other publications on robots with PMA-driven joints, the focus of this work is less on the issue of controlling a particular robot but rather on discussing, developing and proposing a general framework for successful control of any robot with PMA-driven joints. Depending on the robot and its task, joint torques must be provided at an adequate height and speed, and only if these specifications can be met by the actuators, the robot can fulfill its task. As an interface between the robot on the one side and the actuators on the other side, a torque controller for PMA-driven joints will be developed and employed for different applications in this thesis. With this torque controller in place, the complex PMA-driven joint dynamics can be reduced to only the static torque characteristic and the bandwidth of the controller. Since these properties of PMA-driven joints are examined in detail in this dissertation, this thesis forms the necessary basis for the successful application of PMA-driven joints in robotic systems. The simplicity of integrating PMA-driven joints under torque control into robots will be demonstrated by using three different robots. Firstly, a robot with one degree of freedom is positioned with PMA-driven joints, and secondly, the same is demonstrated for a robot with two degrees of freedom. Lastly, a rehabilitation robot with a PMA-driven joint is realized which facilitates a controlled-active-motion therapy, as used after cruciate ligament rupture.","url":"https://doi.org/10.14279/depositonce-14760","authors":["Martens, Mirco"],"tags":["620 Ingenieurwissenschaften und zugeordnete Tätigkeiten","pneumatic-muscle-actuator-driven joints","pneumatic muscle actuator","PMA","pneumatic artificial muscle","PAM","PMA-driven joint","Pneumatisch-muskelaktuierte Gelenke"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.14279/depositonce-14760","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.25417/uic.24242416.v1","name":"Hopping Over Complex Terrain: Sample Efficiency through Reinforcement Learning for Step-Level Control","source":"datacite","abstract":"Navigation of legged robots on complex terrains requires them to achieve precise control of foot placement and speed as a slight miss-step or lack of momentum will lead to failure.

Given a sudden looming visual stimulus at hover, a hummingbird initiates a fast backward translation coupled with a 180-degree yaw turn, which is followed by instant posture stabilization in just under 10 wingbeats. Considering the wingbeat frequency of 40Hz, this aggressive maneuver is accomplished in just 0.2 seconds. Flapping Wing Micro Air Vehicles (FWMAVs) hold great promise for closing this performance gap given its agility. However, the design and control of such systems remain challenging due to various constraints. First, the design, optimization and system integration of a high performance at-scale biologically inspired tail-less hummingbird robot is presented. Designing such an FWMAV is a challenging task under the constraints of size, weight, power, and actuation limitations. It is even more challenging to design such a vehicle with independently controlled wings equipped with a total of only two actuators and be able to achieve animal-like flight performance. The detailed systematic solution for the design is presented, including system modeling and analysis of the wing-actuation system, body dynamics, and control and sensing requirements. Optimization is conducted to search for the optimal system parameters, and a hummingbird robot is built and validated experimentally. An open-source high fidelity dynamic simulation for FWMAVs is developed to serve as a testbed for the onboard sensing and flight control algorithm, as well as design, and optimization of FWMAVs. For simulation validation, the hummingbird robot was recreated in the simulation. System identification was performed to obtain the dynamics parameters. The force generation, open-loop and closed-loop dynamic response between simulated and experimental flights were compared and validated. The unsteady aerodynamics and the highly nonlinear flight dynamics present challenging control problems for conventional and learning control algorithms such as Reinforcement Learning. For robust transient and steady-state flight performance, a robust adaptive controller is developed to achieve stable hovering and fast maneuvering. The model-based nonlinear controller can stabilize the system and adapt to system parameter changes such as wear and tear, thermo effect on the actuator or strong disturbance such as ground effect. The controller is tuned in simulation and experimentally verified by hovering, point-to-point fast traversing, and following by rapid figure-of-eight trajectory. The experimental result demonstrates the state-of-the-art performance of the FWMAV in stationary hovering and fast trajectory tracking tasks, with minimum transient and steady-state error. To achieve animal level maneuvering performance, especially the hummingbirds' near-maximal performance during rapid escape maneuvers, we developed a hybrid flight control strategy for aggressive maneuvers. The proposed hybrid control policy combines model-based nonlinear control with model-free reinforcement learning. The model-based nonlinear control stabilizes the system's closed-loop dynamics under disturbance and parameter variation. With the stabilized system, a model-free reinforcement learning policy trained in simulation can be optimized to achieve the desirable fast movement by temporarily \"destabilizing\" the system during flight. Two test cases were demonstrated to show the effectiveness of the hybrid control method: 1)a rapid escape maneuver observed in real hummingbird, 2) a drift-free fast 360-degree body flip. Direct simulation-to-real transfers are achieved, demonstrating the hummingbird-like fast evasive maneuvers on the at-scale hummingbird robot.","url":"https://doi.org/10.25394/pgs.9937085.v1","authors":["Fei, Fan"],"tags":["Mechanical engineering not elsewhere classified"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.25394/pgs.9937085.v1","addedAt":"2026-08-31T06:34:13.641Z","updatedAt":"2026-08-31T06:34:13.641Z"},{"id":"doi:10.1109/tro.2024.3370050","name":"A Bioinspired Single Actuator-Driven Soft Robot Capable of Multistrategy Locomotion","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tro.2024.3370050","authors":["Rui Chen","Xinyu Zhu","Zean Yuan","Huayan Pu","Jun Luo","Yu Sun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-27T19:37:00Z","doi":"10.1109/tro.2024.3370050","addedAt":"2026-08-31T06:34:13.657Z","updatedAt":"2026-08-31T06:34:13.657Z"},{"id":"doi:10.1109/lra.2024.3487499","name":"State Estimation by Joint Approach With Dynamic Modeling and Observer for Soft Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3487499","authors":["Huichen Ma","Junjie Zhou","Chen-Hua Yeow","Lijun Meng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-28T17:42:26Z","doi":"10.1109/lra.2024.3487499","addedAt":"2026-08-31T06:34:13.658Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.1109/lra.2023.3334098","name":"Trajectory Tracking Control of Dual-PAM Soft Actuator With Hysteresis Compensator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2023.3334098","authors":["Junyi Shen","Tetsuro Miyazaki","Shingo Ohno","Maina Sogabe","Kenji Kawashima"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-11-17T14:22:42Z","doi":"10.1109/lra.2023.3334098","addedAt":"2026-08-31T06:34:13.658Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.25144/21837","name":"ACTIVE CONTROL OF SURGE -

It is presumed that certain followers lack direct access to the states of the leader via a directed graph. This arises challenges in maintaining synchronization and coordination within the network. The proposed control strategy utilizes non-singular fast terminal sliding mode control to accelerate consensus tracking and enhance the convergence of the overall system. This controller is designed to mitigate the impact of actuator faults in the presence of fading channels in the communication network. The effects of such issues on team performance are rigorously analyzed. Based on the Lyapunov stability principle, it has been demonstrated that the controller is capable of providing satisfactory performance for the entire system despite these challenges. Moreover, vehicle synchronization can be effectively maintained. Numerical simulations are conducted to verify the theoretical findings.","url":"https://doi.org/10.1007/s10846-024-02088-1","authors":["Mahmoud Hussein","Youmin Zhang","Zhaoheng Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-18T15:01:51Z","doi":"10.1007/s10846-024-02088-1","addedAt":"2026-08-31T06:34:13.658Z","updatedAt":"2026-08-31T06:34:13.658Z"},{"id":"doi:10.1108/ir-07-2023-0160","name":"Design and preliminary evaluation of a lower limb exoskeleton based on hydraulic actuator","source":"crossref","abstract":"Purpose This paper aims to propose a novel system design and control algorithm of lower limb exoskeleton, which provides walking assistance and load sharing for the wearer.

In this review, we look at the collaboration levels of HRC and what safety actions have been used to address safety. One hundred and ninety-three articles were identified from which, after screening and eligibility stages, 46 articles were used for the extraction stage. Predefined parameters such as: devices, algorithms, collaboration level, safety action, and standards used for HRC were extracted. Despite close human and robot collaboration, 25% of all reviewed studies did not use any safety actions, and more than 50% did not use any standard to address safety issues. This review shows HRC trends and what kind of functionalities are lacking in today’s HRC systems. HRC systems can be a tremendously complex process; therefore, proper safety mechanisms must be addressed at an early stage of development.","url":"https://doi.org/10.3390/jsan10030048","authors":["Janis Arents","Valters Abolins","Janis Judvaitis","Oskars Vismanis","Aly Oraby","Kaspars Ozols"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-07-13T04:26:06Z","doi":"10.3390/jsan10030048","addedAt":"2026-08-31T06:34:15.495Z","updatedAt":"2026-08-31T06:34:15.495Z"},{"id":"doi:10.1063/1.5045817","name":"An articulated finger driven by single-mode piezoelectric actuator for compact and high-precision robot hand","source":"crossref","abstract":"In this paper, a novel finger driven by single-mode piezoelectric actuator for a compact and high-precision robot hand is proposed. Three piezoelectric actuators are articulated by two sets of connecting elements to form the finger. The finger utilizes a single model of the piezoelectric actuator to generate friction force to drive the joint. Without the difficulty to adjust for the coincidence of modal frequencies, the design of the piezoelectric actuator has fewer restrictions on size and structure; thus, the finger has a compact structure. The bidirectional motion of the joint is achieved by changing the temporal phase difference of two excitation signals applied on the two adjacent piezoelectric actuators. In addition, due to the characteristics of piezoelectric drive, such as power cut self-locking and quick response, the finger has a high resolution to realize micromanipulation for high precise movement. In our design, the first order longitudinal vibration mode of the piezoelectric actuator is used to generate the friction force. By using a finite element model, the geometric parameters of the piezoelectric actuator are obtained. A prototype of the finger is fabricated and experimentally investigated, the size (111 × 10 × 10 mm) is approximately 1.5 times that of a human middle finger, and the weight is 0.11 kg. The experimental results indicate that the angular speed of the prototype reaches 6.6 rad/s, the resolution is 20 mrad, and the startup and shutdown response times are 26 ms and 7 ms under a voltage of 400 Vpp, respectively.

A novel drive system architecture is proposed that combines conventional track traction electric drives with an inertial body-stabilization drive based on a flywheel mounted on the pitch axis between the chassis and the body module. The main contribution of the proposed approach is the coordinated control of the traction drives and the inertial actuator based on a unified dynamic model of the platform. A quadratic performance criterion is formulated, and a coordinated optimal control law is synthesized to limit body angular oscillations while accounting for actuator energy consumption. Simulation results for motion over step-like and random terrain irregularities, as well as under external moment disturbances, demonstrate a significant reduction in both peak and root-mean-square pitch-angle deviations relative to configurations without an inertial actuator and with local body stabilization. The results obtained confirm the potential and effectiveness of inertial stabilization drives as part of coordinated drive control systems for tracked mobile platforms intended for special-purpose applications, and indicate prospects for their use in advanced terrestrial robotic platforms and future space robotic systems operating in challenging environments.","url":"https://doi.org/10.3390/s26051517","authors":["Fazylova A","Alipbayev K","Nogaibayeva M","Iliev T","Stoyanov I"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26051517","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41467-026-70259-9","name":"Fast-swimming biohybrid OstraBot with self-trained high-strength muscles.","source":"pubmed","abstract":"Limited muscle force generation remains a major bottleneck in developing stronger, faster, and more efficient biohybrid robots.

This shift highlights the need to address new safety challenges posed by emerging robotic technologies. Currently, there is limited research on robot-related injuries. Methods Robot-related workers' compensation claims from 2001 to 2020 were identified using a keyword search from the Ohio Bureau of Workers' Compensation (OHBWC) database. Descriptive analyses were conducted on this claims dataset. Results From 2001 to 2020, 1076 robot-related claims were identified, with 85% medical-only claims (medical care only and/or ≤ 7 days away from work). Most claimants were male (74.2%), and 51.1% were 25-44 years old. More than half of the claims were due to contact with objects and equipment (57.9%), followed by overexertion and bodily reaction (20.6%). Most injuries occurred in the manufacturing sector (75.1%), followed by the service sector (14.7%). The claims resulted in over $8.3 million in costs. Of this figure, 91% was incurred due to lost-time claims ($7.6 million). Almost 30% of claims included diagnoses from multiple diagnosis groups. Most claims involved working with robotic arms for collaborative applications (75.7%) in a shared workspace. Conclusions Robotics is rapidly evolving to remove workers from hazardous environments and reduce risks from hazardous, repetitive, and manual tasks, but it may introduce new workplace hazards. There is a need to study robot-related injuries, identify high-risk exposures, and develop sector- or application-specific comprehensive safety approaches for safer implementation of robots in the workplace.","url":"https://doi.org/10.1002/ajim.70067","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/ajim.70067","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/s26102925","name":"A Review of Robotic Weeding Modalities for Site-Specific Weed Management.","source":"europepmc","abstract":"Weed control remains a critical challenge in modern crop production, particularly under increasing pressure to reduce chemical inputs and improve environmental sustainability. Recent advances in precision agriculture and robotic systems have enabled site-specific weed management, where interventions are applied selectively based on detected weed locations. While extensive research has focused on improving weed detection algorithms, comparatively less attention has been paid to the characteristics and constraints of different weeding modalities, which ultimately determine field performance. This review presents a systematic analysis of robotic weeding modalities from an actuation-oriented perspective. Specifically, we establish a comprehensive taxonomy of weeding approaches, including mechanical, chemical, thermal, laser-based, electrical, and other emerging methods, and analyze their underlying mechanisms and operational characteristics. Furthermore, we examine the coupling between sensing and actuation, highlighting how different intervention modalities impose distinct requirements on perception outputs. A scenario-based comparison framework is then developed to evaluate the suitability of different modalities across representative agricultural conditions, including pre-emergence control, in-row selective weeding, dense-row crop systems, and large weed situations. Based on this analysis, the limitations of single-modality systems are discussed, and emerging trends toward multi-modality integration and air-ground collaborative weed management are reviewed. Overall, this review shifts the focus from detection-centric approaches to the integration of sensing and actuation in robotic weeding systems and provides a decision-oriented framework to support the design, selection, and deployment of next-generation robotic weed management technologies.","url":"https://doi.org/10.3390/s26102925","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26102925","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.34133/cbsystems.0477","name":"Space Physiology and Technology: Adaptations, Countermeasures, and Opportunities for Wearable Systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.34133/cbsystems.0477","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.34133/cbsystems.0477","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1126/sciadv.adx7189","name":"Air plastron-enabled heat management for enhanced photothermal actuation in underwater soft robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.adx7189","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1126/sciadv.adx7189","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1186/s12984-025-01834-2","name":"Adaptive control ankle robotics training durably improves gait biomechanics in chronic hemiparetic stroke and footdrop.","source":"europepmc","abstract":"","url":"https://doi.org/10.1186/s12984-025-01834-2","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1186/s12984-025-01834-2","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s44172-026-00632-5","name":"Adaptive robot guidance through real-time compliance estimation and dual-modal control.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s44172-026-00632-5","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s44172-026-00632-5","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.3390/gels12020138","name":"Design and Application of Stimuli-Responsive Hydrogels for 4D Printing: A Review of Adaptive Materials in Engineering.","source":"pubmed","abstract":"Stimuli-responsive hydrogels are an emerging class of smart materials with immense potential across biomedical engineering, soft robotics, environmental systems, and advanced manufacturing.

Special attention is given to the growing field of 4D printing, where time-dependent shape and property changes enable dynamic, programmable systems. Unlike existing reviews that often treat materials, stimuli, or applications in isolation, this work introduces a multidimensional comparative framework that connects stimulus-response behavior with fabrication techniques and end-use domains. We also highlight key challenges that limit practical deployment-including mechanical fragility, slow actuation, and scale-up difficulties-and outline engineering solutions such as hybrid material design, anisotropic structuring, and multi-stimuli integration. Our aim is to offer a forward-looking perspective that bridges material innovation with functional design, serving as a resource for researchers and engineers working to develop next-generation adaptive systems.","url":"https://doi.org/10.3390/gels12020138","authors":["Siddique MF","Omar FK","Al-Marzouqi AH"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/gels12020138","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41467-025-62182-2","name":"Muscle-inspired elasto-electromagnetic mechanism in autonomous insect robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-62182-2","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-62182-2","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1002/rcs.70130","name":"Development of a Flexible Parallel Wire Robot for Epicardial Interventions.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/rcs.70130","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/rcs.70130","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41598-026-35309-8","name":"Robust model reference adaptive controller for 3-DOF planar manipulator.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-026-35309-8","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41598-026-35309-8","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.1038/s41598-025-34449-7","name":"Adaptive observed-based backstepping control for quantized robot arms.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-34449-7","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41598-025-34449-7","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"doi:10.48550/arxiv.2603.10670","name":"Dynamic Modeling and Attitude Control of a Reaction-Wheel-Based Low-Gravity Bipedal Hopper","source":"datacite","abstract":"Planetary bodies characterized by low gravitational acceleration, such as the Moon and near-Earth asteroids, impose unique locomotion constraints due to diminished contact forces and extended airborne intervals. Among traversal strategies, hopping locomotion offers high energy efficiency but is prone to mid-flight attitude instability caused by asymmetric thrust generation and uneven terrain interactions. This paper presents an underactuated bipedal hopping robot that employs an internal reaction wheel to regulate body posture during the ballistic flight phase. The system is modeled as a gyrostat, enabling analysis of the dynamic coupling between torso rotation and reaction wheel momentum. The locomotion cycle comprises three phases: a leg-driven propulsive jump, mid-air attitude stabilization via an active momentum exchange controller, and a shock-absorbing landing. A reduced-order model is developed to capture the critical coupling between torso rotation and reaction wheel dynamics. The proposed framework is evaluated in MuJoCo-based simulations under lunar gravity conditions (g = 1.625 m/s^2). Results demonstrate that activation of the reaction wheel controller reduces peak mid-air angular deviation by more than 65% and constrains landing attitude error to within 3.5 degrees at touchdown. Additionally, actuator saturation per hop cycle is reduced, ensuring sufficient control authority. Overall, the approach significantly mitigates in-flight attitude excursions and enables consistent upright landings, providing a practical and control-efficient solution for locomotion on irregular extraterrestrial terrains.","url":"https://doi.org/10.48550/arxiv.2603.10670","authors":["Hari, Shriram","Nikhil, M Venkata Sai","Kumar, R Prasanth"],"tags":["Robotics (cs.RO)","Systems and Control (eess.SY)","FOS: Computer and information sciences","FOS: Computer and information sciences","FOS: Electrical engineering, electronic engineering, information engineering","FOS: Electrical engineering, electronic engineering, information engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2603.10670","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:15.497Z"},{"id":"doi:10.48550/arxiv.2602.10610","name":"Pitch Angle Control of a Magnetically Actuated Capsule Robot with Nonlinear FEA-based MPC and EKF Multisensory Fusion","source":"datacite","abstract":"Magnetically actuated capsule robots promise minimally invasive diagnosis and therapy in the gastrointestinal (GI) tract, but existing systems largely neglect control of capsule pitch, a degree of freedom critical for contact-rich interaction with inclined gastric walls. This paper presents a nonlinear, model-based framework for magnetic pitch control of an ingestible capsule robot actuated by a four-coil electromagnetic array. Angle-dependent magnetic forces and torques acting on embedded permanent magnets are characterized using three-dimensional finite-element simulations and embedded as lookup tables in a control-oriented rigid-body pitching model with rolling contact and actuator dynamics. A constrained model predictive controller (MPC) is designed to regulate pitch while respecting hardware-imposed current and slew-rate limits. Experiments on a compliant stomach-inspired surface demonstrate robust pitch reorientation from both horizontal and upright configurations, achieving about three to five times faster settling and reduced oscillatory motion than on-off control. Furthermore, an extended Kalman filter (EKF) fusing inertial sensing with intermittent visual measurements enables stable closed-loop control when the camera update rate is reduced from 30 Hz to 1 Hz, emulating clinically realistic imaging constraints. These results establish finite-element-informed MPC with sensor fusion as a scalable strategy for pitch regulation, controlled docking, and future multi-degree-of-freedom capsule locomotion.","url":"https://doi.org/10.48550/arxiv.2602.10610","authors":["Wang, Chongxun","Shen, Zikang","Rathore, Apoorav","Udombeh, Akanimoh","Teng, Harrison","Xia, Fangzhou"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2602.10610","addedAt":"2026-08-31T06:34:15.497Z","updatedAt":"2026-08-31T06:34:15.497Z"},{"id":"doi:10.5281/zenodo.17631973","name":"Junior","source":"datacite","abstract":"The below are copy pasted conversations with a trained AI Absolutely — I can build **the complete humanoid robot platform** using *all* of your known work, inventions, innovations, concepts, mathematical frameworks, energy systems, organ models, and recursive architectures.

Various kinds of adhesion, actuation and locomotion systems exist for the different needs of climbing robots enabling them to work in different circumstances with different abilities, both on ferrous-magnetic and non-ferrous- magnetic surfaces, ground and walls and with slow or fast motion. Today there are many types of adhesion: magnetic, vacuum and dry, etc. Likewise, different sorts of locomotion are popular: legged locomotion, tracked locomotion and wheeled locomotion. However, there are increasing problems using climbing robots, such as complex structures, stepping over obstacles and high price. Some of these limitations are gradually being solved. This thesis develops a robotic structure, named Hubbot. It will achieve a combined set of motions, consisting of linear motion, rotational motion, leg extension/retraction motion and interference avoidance motion. It has a simple and light weight structure. From the perspective of a simple design, a hub will be presented as well as some symmetrical legs instead of a multi- joint legged moving structure. From the perspective of reducing the weight, a rack and pinion gear is driven by a hung, reversible motor. From the perspective of operating savings, Electric Linear Actuators (ELA) are suggested to replace pneumatic cylinders. A literature review described drawbacks of common locomotion mechanism, such as more complicated structure in legged locomotion mechanism than other mechanisms, especially translation locomotion mechanism. With respect to actuation mechanisms, ELA has the obvious advantages of light weight and high force and a simple structure among all actuators, even alternative to pneumatic actuator. Likewise, with comparison to other adhesion mechanisms, vacuum suction mechanisms present the simpler structure as well as flexible working terrains, but they could not work on rough or cracked surface. (A table makes the comparisons clearer and much more.) Requirements for a window cleaning robot, such as light weight and working conditions, are presented. To address the problems mentioned before, the potential design using a hub is described. The rack and pinion gears mentioned above that are separately mounted to the two modules drive them to linearly move successively using one servo motor. However, the rack must totally separate from the pinion before each module is driven to rotate respect to each other by another servo motor. These reduce the number of motors needed. Those symmetrical pillars may avoid a complicated Degree of Freedom (DOF) as well as help the robot move and overcome barriers flexibly via 4 ELAs and 4 fixed legs. Further, the four position arrangements of these legs are proposed and compared as well as the assembly of these legs and solenoid valves. (A table makes the comparisons clearer.) Most importantly, based on the working situations of this robot, the kinematic and dynamic analysis regarding its velocity and acceleration, adhesion force and motor force, are performed. Furthermore, a structural optimization of the rotational mechanism is shown by three different bearing arrangements. The aim is to choose the best one to ensure the rigidity of the shaft and reduce the cost of the robot. Also, the method of attaching these kinds of bearings is indicated and compared by 3D CAD models. (A table makes the comparisons clearer.) Finally, a functional embodiment design is presented as well as its whole structure’s exploded view, consisting of three mechanisms: locomotion, adhesion and actuation. The four motions are highlighted showing in detail through their sequence formulations.","url":"https://doi.org/10.26021/3076","authors":["Yu, ZhiHong"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.26021/3076","addedAt":"2026-08-31T06:34:15.498Z","updatedAt":"2026-08-31T06:34:43.551Z"},{"id":"doi:10.1184/r1/12707963.v1","name":"ALFA: A Dataset for UAV Fault and Anomaly Detection","source":"datacite","abstract":"The recent growth in the use of Autonomous Aerial Vehicles (AAVs) has increased concerns about the safety of the autonomous vehicles, the people, and the properties around the flight path and onboard the vehicle. Much research is being done on new regulations, more robust systems are designed to address the concerns, and new methods and algorithms are introduced to detect the potential hardware and software issues. This dataset presents several fault types in control surfaces of a fixed-wing Unmanned Aerial Vehicle (UAV) for use in Fault Detection and Isolation (FDI) and Anomaly Detection (AD) research. Currently, the dataset includes processed data for 47 autonomous flights with 23 sudden full engine failure scenarios and 24 scenarios for seven other types of sudden control surface (actuator) faults, with a total of 66 minutes of flight in normal conditions and 13 minutes of post-fault flight time. It additionally includes many hours of raw data of fully-autonomous, autopilot-assisted and manual flights with tens of fault scenarios. The ground truth of the time and type of faults is provided in each scenario to enable the evaluation of new methods using the dataset. We have also provided the helper tools in several programming languages to load and work with the data and to help the evaluation of a detection method using the dataset. A set of metrics is proposed to help to compare different methods using the dataset. Most of the current fault detection methods are evaluated in simulation and as far as we know, this dataset is the only one providing the real flight data with faults in such capacity. We hope it will help advance the state-of-the-art in Anomaly Detection or FDI research for Autonomous Aerial Vehicles and mobile robots to enhance the safety of autonomous and remote flight operations further. Hardware: The platform used for collecting the dataset is a custom modification of the Carbon Z T-28 model plane. The plane has 2 meters of wingspan, a single electric engine in the front, ailerons, flaperons, an elevator, and a rudder. We equipped the aircraft with a Holybro PX4 2.4.6 autopilot, a Pitot Tube, a GPS module, and an Nvidia Jetson TX2 onboard computer. In addition to the receiver, we also equipped it with a radio for communication with the ground station. Software: The Pixhawk autopilot uses a custom version of Ardupilot/ArduPlane firmware to control the plane in both manual and autonomous modes and to create the simulations. The original firmware is modified from ArduPlane v3.9.0beta1 to allow disabling control surfaces during the flight. The onboard computer uses Robot Operating System(ROS) Kinetic Kame on Linux Ubuntu 16.04 (Xenial) to read the flight and state information from the Pixhawk using MAVROS package (the MAVLink node for ROS).

This can limit participation and performance of daily living activities. Most of the existing exoskeletons on the market are bulky, heavy, and unattractive, which can lead to low rates of utilization. Therefore, there is a critical need to design novel exoskeletons that address users’ broad needs. The purpose of this dissertation was to develop and evaluate a pediatric soft pneumatic exoskeleton to improve range of motion, function, and the performance of daily activities for children who have UE disabilities. ☐ Aim 1 consisted of a systematic review of the evidence on the effectiveness of UE exoskeletons and robot-assisted devices for pediatric rehabilitation. Sixty articles were included. Most evaluated body structure and function and activity effects with less emphasis on participation. Most effects were positive. Devices were primarily evaluated in clinical or laboratory, rather than natural, environments. Users had numerous negative perceptions about the devices. A need for increased rigor in research study design was detected. Across populations, devices, settings, interventions, and dosing schedules, UE exoskeletons and robot-assisted devices may improve function, activity, and perhaps participation for children with physical disabilities. ☐ Aim 2 involved the development and comparative evaluation of pneumatic actuators for the Playskin AirTM. Textile pneumatic actuators were developed and evaluated with the goal of providing full assistance to lift the arm of a model of an 11-year-old male beyond 120 degrees of shoulder abduction. Two fabrics and a variety of sealing techniques, methods of attachment, and actuator shapes were comparatively evaluated using textile and functional tests. The results identified that both fabrics and one of the three sealing techniques were effective for creating air-tight, functional actuators. Actuators were more effective when the bands attaching them were closer to the axilla. Rectangular and wing-shaped actuators, both lifting the model’s arm above 120 degrees of abduction, were more effective than Y-shaped actuators. The results showed that multiple designs and materials may be acceptable for building textile pneumatic actuators to lift the full weight of a child’s arm. ☐ Aim 3 consisted of the design and development of the first pediatric pneumatic exoskeletal garment aimed at enhancing arm mobility for children with UE movement impairments. The two parts for Aim 3 were an interview and the exoskeletal garment design. ☐ For the Aim 3 interview, A qualitative study design involving an in-depth, semi-structured interview was performed with families able to communicate in English and with at least one child 3-16 years of age who reportedly needs help lifting and holding up their arm(s). Responses were analyzed using NVivo qualitative data analysis software (QSR International Pty Led.). Twenty-two parents and 12 children with UE disability among 21 families were interviewed. Child participants were 3-15 years old (Mean=8.1, S.D.=4.1). Families identified key personal care, function and mobility, manual interaction, academic, recreation, and social activities they would like devices to support. Families rated a variety of functional, expressive, aesthetic, and accessibility needs for exoskeletons in terms of relative importance. Families pointed out that their current UE wearable assistive devices are better at meeting some functional needs than they are at meeting other needs. Finally, families discussed their suggestions for the design of future exoskeletons, including preferences for attachment mechanisms, fasteners, and control systems. ☐ In the Aim 3 exoskeletal garment design, the researcher successfully developed a design for the novel, soft, pneumatic exoskeletal garment, the Playskin AirTM, aimed at supporting shoulder abduction for children with UE disabilities.

As such, it is desirable to use a robot arm that has limited joint torques to not injure the nearby person and interacts with the environment to explore new possibilities for completing a task. By bracing against the environment, robots can expand their reachable workspace, which would otherwise be inaccessible due to exceeding actuator torque limits, and accomplish tasks beyond their design specifications. However, motion planning for complex contact-rich tasks requires reasoning through the permutations of different possible contact modes and bracing locations, which grow exponentially with the number of contact points and links in the robot. To address this combinatorial problem, we developed INSAT, which interleaves graph search to explore the manipulator joint configuration and the contact mode space with incremental trajectory optimizations seeded by neighborhood solutions to find a dynamically feasible trajectory through contact. In this paper, we present recent additions to the INSAT algorithm that improve its runtime performance. In particular, we propose Lazy INSAT with reduced optimization rejection that systematically procrastinates its calls to trajectory optimization while reusing feasible solutions that violate boundary constraints. The algorithm is evaluated on a heavy payload transportation task in simulation and on physical hardware. In simulation, we show that Lazy INSAT can discover solutions for tasks that cannot be accomplished within its design limits and without interacting with the environment. In comparison to executing the same trajectory without environment support, we demonstrate that the utilization of bracing contacts reduces the overall torque required to execute the trajectory.","url":"https://doi.org/10.48550/arxiv.2210.08627","authors":["Natarajan, Ramkumar","Johnston, Garrison L.

For achieving this goal, past work has concentrated on force control algorithms at the system level with limited focus on performance expansion at the actuator level. We present a comprehensive literature review on robot force control, including algorithms, specialized actuators, and robot control software. A robot force control testbed was developed using Schunk's PowerCube 6-DOF Arm and a six-axis ATI force/torque sensor. Using parameter identification experiments, manipulator module inertias and the motor torque constant were estimated. Experiments were conducted to study the practical issues involved in implementing stable contact transitions and programmable endpoint impedance. Applications to human augmentation, virtual fixtures, and teleoperation are discussed. These experiments are used as a vehicle to understand the performance improvement achievable at the actuator level. The approach at UTRRG has been to maximize the choices within the actuator to enhance its intelligence. Drawing on this 20-year research history in electromechanical actuator architecture, we propose a new concept that mixes two inputs, distinct in their velocity ratios, within the same dual actuator called a Force/Motion Actuator (FMA). Detailed kinematic and dynamic models of this dual actuator are developed. The actuator performance is evaluated using simulations with an output velocity specification and resolving input trajectories using a minimum-norm solution. It is shown that a design choice of 14:1 motion scaling between the two inputs results in good sensitivity to output force disturbances without compromising velocity tracking performance.","url":"https://doi.org/10.48550/arxiv.1402.5461","authors":["Rabindran, Dinesh"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2014","doi":"10.48550/arxiv.1402.5461","addedAt":"2026-08-31T06:34:15.498Z","updatedAt":"2026-08-31T06:34:15.498Z"},{"id":"doi:10.48550/arxiv.1711.05379","name":"A Systematic Literature Review of Experiments in Socially Assistive Robotics using Humanoid Robots","source":"datacite","abstract":"We perform a Systematic Literature Review to discover how Humanoid robots are being applied in Socially Assistive Robotics experiments.

Dort werden flexibel nutzbare und mit Sensoren ausgestattete Roboter gebraucht, da in diesen apriori unbekannten Umgebungen nicht alles voraus geplant und simuliert werden kann. Für diese Anwendungen werden Roboter benötigt, die leicht sind und dennoch Kraft ausüben können, die effizient und flexibel Kollisionen vermeiden können, die interaktiv auf Menschen reagieren können, während sie ihre Aufgaben verrichten, wie z.B. eine Last halten und dennoch auf Berührung ausweichen. Typischerweise können diese Aufgabenstellungen mit Hilfe von kinematisch redundanten Robotern erfüllt werden, da hier zusätzliche Freiheitsgrade vorhanden sind, mit denen auf variierende Aufgabenstellungen und veränderliche Umwelteinflüsse reagiert werden kann. Zur Nutzung von kinematisch redundanten Robotern wurden bereits viele Algorithmen und Methoden entwickelt. Ausgehend von den am Institut für Robotik und Mechatronik entwickelten Systemen einer neuen Robotergeneration ist es nun möglich, ein Rahmenkonzept zur Nutzung von redundanten Robotern zu schaffen, analog zu früheren Tagen, als Interpolatoren, Kinematik, inverse Kinematik etc. zu Industrierobotersteuerungen zusammengefasst wurden, die damit den Industrierobotern zum Durchbruch verhalfen. Daher wird in dieser Arbeit ein Konzept zur Nutzung und Bedienung kinematisch redundanter Roboter entwickelt. Aufgrund der Tatsache, dass sehr viele verschiedene Verwendungszwecke der kinematischen Redundanz möglich sind, die einander möglicherweise sogar widersprechen, ist die Wahl solcher Verwendungszwecke, Methoden und Algorithmen sehr aufgabenspezifisch. Im ersten Teil der Arbeit werden Algorithmen und Methoden zur Verwendung der kinematischen Redundanz einander gegenübergestellt, aus diesen wird ein weittragender Algorithmus ausgewählt und in der Tiefe untersucht. Dieser wird in vielen verschiedenen Anwendungsfeldern eingesetzt, wie in der Singularitätsbehandlung, verschiedenen Verwendungszwecken der kinematischen Redundanz und der interaktiven intuitiven Verwendung von redundanten Manipulatoren. Im zweiten Teil wird eine Systemarchitektur und eine Benutzerschnittstelle konzipiert, mit der ein Nicht in die Lage versetzt wird, einen kinematisch redundanten Roboter zu bedienen. Eines der Hauptergebnisse aus der Gegenüberstellung der verschiedenen Algorithmen zur Behandlung kinematischer Redundanzen ist, dass es nicht \"den Besten\" gibt. Daher sollte die Einbettung mehrerer verschiedener Algorithmen in die Systemarchitektur eines ServiceRoboters vorgesehen werden. Ein weiteres Ergebnis ist, dass durch die Wahl von Methoden der \"Constraint Optimization\" anstelle der weitverbreiteten Moore-Penrose Pseudo Inverse Anforderungen realer Systeme, wie z.B. endliche Gelenkgeschwindigkeiten, leicht eingebettet werden können. Auch die Koordination von hochgradig redundanten mobilen Manipulatoren Nebenbedingungen kann mit solchen konvexen Optimierungsproblemen in Echtzeit behandelt werden. Die Behandlung von Singularitäten nutzt eben diese Ungleichungs-Nebenbedingungen. Die Singularitätsbehandlung wird in dieser Arbeit an nicht-redundanten Industrierobotern untersucht, der Formalismus wird danach auf redundante Manipulatoren ausgedehnt. In der Erweiterung des Formalismus auf redundante Manipulatoren werden verschiedene Verwendungszwecke untersucht, wie z.B. Geschicklichkeitssteigerung, Sollkonfiguration, Kollisionsvermeidung, interaktive Verwendung der Redundanz etc. Weiterhin werden Punkt-zu-Punkt-Bewegungen untersucht, da durch die Verwendung numerisch iterativer Algorithmen die Konvergenz in Echtzeit nicht garantiert werden kann.

It also transmits the sensed data from the MRV to the signal processing unit. The MRV with legs on the railway was moving due to its high-frequency vibration.

Much research is being done on new regulations, more robust systems are designed to address the concerns, and new methods and algorithms are introduced to detect the potential hardware and software issues. This dataset presents several fault types in control surfaces of a fixed-wing Unmanned Aerial Vehicle (UAV) for use in Fault Detection and Isolation (FDI) and Anomaly Detection (AD) research. Currently, the dataset includes processed data for 47 autonomous flights with 23 sudden full engine failure scenarios and 24 scenarios for seven other types of sudden control surface (actuator) faults, with a total of 66 minutes of flight in normal conditions and 13 minutes of post-fault flight time. It additionally includes many hours of raw data of fully-autonomous, autopilot-assisted and manual flights with tens of fault scenarios. The ground truth of the time and type of faults is provided in each scenario to enable the evaluation of new methods using the dataset. We have also provided the helper tools in several programming languages to load and work with the data and to help the evaluation of a detection method using the dataset. A set of metrics is proposed to help to compare different methods using the dataset. Most of the current fault detection methods are evaluated in simulation and as far as we know, this dataset is the only one providing the real flight data with faults in such capacity. We hope it will help advance the state-of-the-art in Anomaly Detection or FDI research for Autonomous Aerial Vehicles and mobile robots to enhance the safety of autonomous and remote flight operations further. Hardware: The platform used for collecting the dataset is a custom modification of the Carbon Z T-28 model plane. The plane has 2 meters of wingspan, a single electric engine in the front, ailerons, flaperons, an elevator, and a rudder. We equipped the aircraft with a Holybro PX4 2.4.6 autopilot, a Pitot Tube, a GPS module, and an Nvidia Jetson TX2 onboard computer. In addition to the receiver, we also equipped it with a radio for communication with the ground station. Software: The Pixhawk autopilot uses a custom version of Ardupilot/ArduPlane firmware to control the plane in both manual and autonomous modes and to create the simulations. The original firmware is modified from ArduPlane v3.9.0beta1 to allow disabling control surfaces during the flight. The onboard computer uses Robot Operating System(ROS) Kinetic Kame on Linux Ubuntu 16.04 (Xenial) to read the flight and state information from the Pixhawk using MAVROS package (the MAVLink node for ROS).

The robotic gripper operates as follows: after locating and contacting the foreign body, the last segment of the gripper is expanding or contracting to match the size and catch the targeted object, then pushes forward, or bends it with its legs and starts to remove the object by a rhythmic peristaltic (periodically repeated) motion. This mode of the gripper’s operation allows removing bodies of different sizes from the human body without damaging the surrounding tissues, especially the blood vessels. Both the segments and legs of the gripper are made of dielectric elastomer actuators (DEAs) capable of large deformations under the influence of an external electric field (EEF). A central pattern generator (CPG)- based controller and a Rowat-Selverston type oscillator are selected to control both discrete and rhythmic motions based on electrical voltage – equivalent elastic strain relations of the orthotropic silicone elastomer obtained by the finite element analysis (FEA). The robotic gripper is modelled and studied by the ANSYS Workbench and Matlab/Simulink software. The performed computer modeling shows that due to the simple modular structure and CPG controller, the proposed robotic gripper is much faster, more adaptive and shows better response compared with its pneumatic actuated analogues.","url":"https://doi.org/10.53297/18293387-2023.2-41","authors":["N.B.

Grippers plays a major role in all pick and place application industries. Those are connected as end effectors to realize and develop a task in an industrial work floor. Pneumatic gripper works with the principle of compressed air. The gripper is connected to a compressed air supply. When air pressure is applied on the piston, the gripper gets opened while the air gets exist from the piston it gets closed. It is possible to control the force acting on the gripper by controlling the air pressure with the help of the valve. The results from these experiments demonstrate that the master-slave attitude control can be realized by using an accelerometer and a simple analytical model of the robot arm. The trajectory control also was realized for a square trajectory by using an analytical model and a compact control system. C measured one is relatively large compared with typical robot arm. This is because by a friction that is existing in a rod-less type flexible pneumatic cylinder. The control performance can be improved by reducing the friction or by improving the control scheme.

The gripper is unique in that it can both grasp an object and retract the object using a single electric motor. Once the object is grasped and retracted, it can also be extended and released by reversing the direction of the motor. The new gripper is driven by a single cam mechanism with two cam profiles that control both the extension and retraction of the mechanism as well as the opening and closing of the gripper fingers. The cam driven approach includes an extension spring that allows the gripper fingers to automatically grasp and release different sized objects. This paper presents the new robotic gripper, including a discussion of its design principles. The advantage of this mechanism is that it only needs one actuator to complete a high-volume fixed automation task that usually requires two actuators. Thus, the proposed gripper design has the potential to have lower power consumption and improved energy efficiency when compared to conventional approaches that use some combination of pneumatic and electric actuators.","url":"https://doi.org/10.1115/detc2024-142774","authors":["Hunter Jones","Brian J.

IPMC actuation for micro gripping is produced by deflecting material according to bending moment theory. An external electric field generated by suitable RC circuit causes this deflection. It is found that an IPMC actuates from 1–5 seconds. The maximum jaw opening and closing position of micro gripper are found to be 5 mm and 0.5 mm respectively.

However, as technological advancements continue to be incorporated, a gap is created by the quality–cost ratio associated with using technologically advanced solutions. For example, many open-source prosthetics provide relatively inexpensive devices, but they often sacrifice the ability to grip irregularly shaped or smooth objects. For instance, doorknobs are difficult to grip using the typical hard robotics approach but can be gripped using soft robotic techniques. Prior work with soft robotics successfully used compressed air and a small granular material (coffee grounds) to build a gripper that can hold various objects. However, the use of compressed air makes these devices relatively slow, and the need for an air compressor limits the applicability of this design. Our primary goal was to explore the feasibility of a soft robotic approach that utilizes ferromagnetic granular materials to grip an object via the granular jamming transition that is induced with an external magnetic field. The granular material is placed inside flexible membranes made of polyisoprene, wherein the granular materials can go from a more relaxed state to a more rigid state depending on the strength of the magnetic field. The flexible membrane also allows the object to be held and then return to its original state when released. A solenoid provides a magnetic field that is easily turned on and off to jam and unjam the magnetic granular material and thus allows us to hold an object in place without the use of compressed air. In searching for a magnetic granular material, we found that iron filings work well, as they easily conform to the shape of the object. We have observed success in holding and releasing several smooth knobs as well as more angular shapes. This work will further the development of a low-cost but high- functioning universal gripper with applications in prosthetics and pick-and-place devices, as well as a multitude of industrial applications.","url":"https://doi.org/10.1063/10.0022470","authors":["Marigordon Varner","Tori Snyder"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-18T18:47:41Z","doi":"10.1063/10.0022470","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/isie.2013.6563748","name":"Scheduling dual gripper robotic cells with a hub machine","source":"crossref","abstract":"","url":"https://doi.org/10.1109/isie.2013.6563748","authors":["Mehdi Foumani","M.

Computing the poses of a given object in a modular fixture is a basic but tedious technique for designing and using such fixtures. This article presents an efficient algorithm for computing the poses. Starting from a unified expression of the outline of an object, this algorithm searches all matching poses automatically. If the outline consists of straight lines and circular arcs only, all the unknown variables can be calculated sequentially by substituting known (or tentative) data in respective expressions, without solving complicated simultaneous equations. When applied to arbitrary outlines, it involves nothing more than common interpolation. The search process is visualized through diagrams that clearly display the occurrence of matching poses. The computer programs are universally applicable. Only the data of the object outline and the fixture configuration need be input.

The main limitations of such systems are small grasping force resulted from properties of soft actuators and lacking variable stiffness of soft robotic grippers, which prevent them from a larger wide range of applications. This article proposes a shape-memory alloy (SMA)-based soft gripper with variable stiffness composed of three robotic fingers for grasping compliantly at low stiffness and holding robustly at high stiffness. Each robotic finger mainly consisted of stiff parts and two variable stiffness joints is installed on the base with a specific angle. The paraffin as a variable stiffness material in the joint can be heated or cooled to change the stiffness of the robotic fingers. Results of experiments have shown that a single robotic finger can approximately achieve 18-fold stiffness enhancement. Each finger with two joints can actively achieve multiple postures by both changing the corresponding stiffness of joints and actuating the SMA wire. Based on these principles, the gripper can be applied to grasp objects with different shapes and a large range of weights, and the maximum grasping force of the gripper is increased to about 10 times using the variable stiffness joints. The final experiment is conducted to validate variable stiffness of the proposed soft grippers grasping an object.","url":"https://doi.org/10.1177/1729881420907813","authors":["Mingfang Liu","Lina Hao","Wei Zhang","Zhirui Zhao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-02-24T05:36:53Z","doi":"10.1177/1729881420907813","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.5772/37010","name":"Control of Efficient Intelligent Robotic Gripper Using Fuzzy Inference System","source":"crossref","abstract":"","url":"https://doi.org/10.5772/37010","authors":["A.M.

Investigations were conducted to determine how the viscosity of the liquid elastomer affected how the robotic actuator bent. The gripper's curvature, response time, and load-carrying capacity were measured, and the relation between applied air pressure and these characteristics was examined. Moreover, the effect of environmental factors (dry, wet and oily) on the load-carrying capacity of the gripper was investigated. These findings demonstrate that as applied air pressure is increased, the gripper's response time, curvature, and load-carrying capacity all increase. For all applied pressures, the highest load carrying capacity of the gripper was observed in dry environment. By altering the waiting time, the elastomer's viscosity could be managed. The ideal waiting time was found to be between 3 and 4 minutes for the optimal bending performance. If the soft robotic gripper is improved to achieve greater performance, it will be suitable for real-world applications.","url":"https://doi.org/10.17714/gumusfenbil.1244719","authors":["Murat Eroğlu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-02T14:09:18Z","doi":"10.17714/gumusfenbil.1244719","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1007/978-3-030-86826-0_6","name":"Model-Algorithmic Support of Robotic Gripper for Manipulating Agricultural Products","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-030-86826-0_6","authors":["Andrey Ronzhin","Tien Ngo","Quyen Vu","Vinh Nguyen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-09-10T15:03:13Z","doi":"10.1007/978-3-030-86826-0_6","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.31031/eme.2026.06.000641","name":"Design and Fabrication of a Monolithic, Sensorized Soft Robotic Gripper using Multi-Material PolyJet Additive Manufacturing","source":"crossref","abstract":"","url":"https://doi.org/10.31031/eme.2026.06.000641","authors":["Zhuo Meng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-02-28T05:44:34Z","doi":"10.31031/eme.2026.06.000641","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.3401/poms.1080.0053","name":"Approximations to Optimal\n                    <i>k</i>\n                    ‐Unit Cycles for Single‐Gripper and Dual‐Gripper Robotic Cells","source":"crossref","abstract":"We consider the problem of scheduling operations in bufferless robotic cells that produce identical parts using either single‐gripper or dual‐gripper robots. The objective is to find a cyclic sequence of robot moves that minimizes the long‐run average time to produce a part or, equivalently, maximizes the throughput. Obtaining an efficient algorithm for an optimum k‐unit cyclic solution ( k ≥ 1) has been a longstanding open problem. For both single‐gripper and dual‐gripper cells, the approximation algorithms in this paper provide the best‐known performance guarantees (obtainable in polynomial time) for an optimal cyclic solution. We provide two algorithms that have a running time linear in the number of machines: for single‐gripper cells (respectively, dual‐gripper cells), the performance guarantee is 9/7 (respectively, 3/2). The domain considered is free‐pickup cells with constant intermachine travel time. Our structural analysis is an important step toward resolving the complexity status of finding an optimal cyclic solution in either a single‐gripper or a dual‐gripper cell.

Each finger of the gripper consists of multi-layers with a honeycomb sandwich structure acting as a core wrapped by a fabric sheet and sealed by a latex membrane. This structure can transit between unjammed (flexible) and jammed (rigid) states thanks to the vacuum pressure. Various materials of honeycomb structure, fabric, and reinforcements are investigated to seek optimal combinations for making the jamming fingers. Then, such fingers are deployed in experiments to evaluate the stiffness and the surface friction with different loads in terms of with or without vacuum. Vacuum pressure boosts the stiffness and friction of all the jamming fingers compared with the without-vacuum case. Attached to a gripper, the jamming finger shows good performance in diverse manipulation with food, a metal component, a toy, a can, and a bottle. Furthermore, the variable-stiffness finger under vacuum pressure can be utilized to perform assembly and installation operations such as pushing a bolt into an aligned hole.","url":"https://doi.org/10.3390/act13090359","authors":["Yu Cheng Chung","Wai Tuck Chow","Van Pho Nguyen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-09-16T10:56:57Z","doi":"10.3390/act13090359","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/reedcon57544.2023.10150673","name":"Multifinger Robotic Gripper: A Review","source":"crossref","abstract":"","url":"https://doi.org/10.1109/reedcon57544.2023.10150673","authors":["Shamsh Parveen","Mohammad Suhaib","Muhammad Abdullah Majid"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-06-16T17:18:39Z","doi":"10.1109/reedcon57544.2023.10150673","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1016/s0967-0661(01)00152-6","name":"Impedance control of a robotic gripper for cooperation with humans","source":"crossref","abstract":"","url":"https://doi.org/10.1016/s0967-0661(01)00152-6","authors":["Ashish Dutta","Goro Obinata"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2002-10-14T15:12:20Z","doi":"10.1016/s0967-0661(01)00152-6","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/codit62066.2024.10708619","name":"An Automated Robotic Gripper Design Framework","source":"crossref","abstract":"","url":"https://doi.org/10.1109/codit62066.2024.10708619","authors":["Georgia Peleka","Ioannis Mariolis","Dimitrios Giakoumis","Dimitrios Tzovaras"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-18T17:27:18Z","doi":"10.1109/codit62066.2024.10708619","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/mecatronics.2014.7018563","name":"An underactuated adaptive 3D printed robotic gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mecatronics.2014.7018563","authors":["Kuat Telegenov","Yedige Tlegenov","Almas Shintemirov"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-01-27T10:28:15Z","doi":"10.1109/mecatronics.2014.7018563","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/tase.2023.3312296/mm2","name":"Design and Development of a New Bioinspired Hybrid Robotic Gripper for Multi-Mode Robust Grasping_supp1-3312296.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tase.2023.3312296/mm2","authors":["Qingsong Xu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-09-14T14:07:38Z","doi":"10.1109/tase.2023.3312296/mm2","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1002/aisy.202370033","name":"Fabric‐Based Star Soft Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1002/aisy.202370033","authors":["Ignacio Andrade-Silva","Joel Marthelot"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-22T06:18:14Z","doi":"10.1002/aisy.202370033","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/icarcv.2008.4795780","name":"Design and development of flexible robotic gripper for handling food products","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icarcv.2008.4795780","authors":["Rosidah Sam","Samia Nefti"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-03-06T00:55:27Z","doi":"10.1109/icarcv.2008.4795780","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/access.2025.3587215/mm1","name":"Lightweight and high-payload robotic gripper using shape-memory-alloy actuator and selflocking mechanism_supp1-3587215.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/access.2025.3587215/mm1","authors":["Toshihiro NISHIMURA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-11T17:45:10Z","doi":"10.1109/access.2025.3587215/mm1","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.32548/2021.me-04223","name":"Integrating Electromagnetic Acoustic Transducers in a Modular Robotic Gripper for Inspecting Tubular Components","source":"crossref","abstract":"Tubular structures are critical components in infrastructure such as power plants. Throughout their life, they are subjected to extreme conditions or suffer from defects such as corrosion and cracks. Although regular inspection of these components is necessary, such inspection is limited by safety-related risks and limited access for human inspection. Robots can provide a solution for automatic inspection. The main challenge, however, lies in integrating sensors for nondestructive evaluation with robotic platforms. As part of developing a versatile lizard-inspired tube inspector robot, in this study the authors propose to integrate electromagnetic acoustic transducers into a modular robotic gripper for use in automated ultrasonic inspection. In particular, spiral coils with cylindrical magnets are integrated into a novel friction-based gripper to excite Lamb waves in thin cylindrical structures. To evaluate the performance of the integrated sensors, the gripper was attached to a robotic arm manipulator and tested on pipes of different outer diameters. Two sets of tests were carried out on both defect-free pipes and pipes with simulated defects, including surface partial cracking and corrosion. The inspection results indicated that transmitted and received signals could be acquired with an acceptable signal-to-noise ratio in the time domain. Moreover, the simulated defects could be successfully detected using the integrated robotic sensing system.","url":"https://doi.org/10.32548/2021.me-04223","authors":["Hamidreza Nemati","Fernando Alvidrez","Ankit Das","Nihar Masurkar","Manoj Rudraboina","Hamid Marvi","Ehsan Dehghan-Niri"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-07-08T15:04:58Z","doi":"10.32548/2021.me-04223","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/robot.1997.620067","name":"3-D flexible fixturing using a multi-degree of freedom gripper for robotic fixtureless assembly","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1997.620067","authors":["W.J.

Furthermore, existing adaptive grippers typically rely on active control strategies and sensor-based feedback, which increase system complexity, energy consumption, and maintenance demand. This study presents a novel, low-maintenance adaptive gripper capable of securely grasping objects with a wide range of mechanical properties, without requiring an external active control mechanism. The proposed gripper is a cylindrical, multi-layered structure composed of four curved beams separated by interlayer gaps, enabling passive transition through five discrete stiffness states. Initially soft, the structure progressively stiffens with increasing axial displacement, reaching distinct stiffness levels at specific displacement values. Ultimately, when all interlayer gaps are fully closed, the gripper reaches its maximum stiffness, equivalent to the elastic modulus of the fabrication material. The gripper returns to its original low-stiffness state once the displacement is removed, demonstrating fully reversible passive adaptation. The effective elastic modulus range spans several orders of magnitude, from hundreds of kilopascals (kPa), suitable for handling soft and light objects, to gigapascals (GPa), enabling robust gripping of rigid and heavy ones. Finite element method simulations validate the gripper’s performance, illustrating the five-state stiffness modulation as well as corresponding stress distribution and reaction forces. The gripper is fabricated using three-dimensional printing technology and experimentally tested to validate the feasibility of the design as a proof-of-concept.","url":"https://doi.org/10.1088/1361-665x/adf479","authors":["Naser Sharafkhani","Haifeng Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-25T22:51:34Z","doi":"10.1088/1361-665x/adf479","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1109/icra48891.2023.10160922","name":"Passive robotic gripper using a contact-based locking mechanism","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra48891.2023.10160922","authors":["Issei Nate","Zhongkui Wang","Shinichi Hirai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-07-04T17:20:56Z","doi":"10.1109/icra48891.2023.10160922","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.4028/www.scientific.net/amm.479-480.742","name":"Distributed Control Intelligent Robotic Gripper","source":"crossref","abstract":"An intelligent gripper is designed with embedded distributed control structure for overcoming the uncertainty of grasped object mass and soft/hard features.

While the shape morphing of the grippers is cable-driven, the stiffness variation is enabled by layer jamming. The inherent flexibility makes compliant grippers suitable for tasks such as grasping soft and irregular objects. However, their relatively low load capacity due to low structural stiffness limits their applications. Variable stiffness robotic grippers have the potential to address this challenge as their stiffness can be tuned on demand based on the needs of tasks. Layer jamming is an emerging method for variable stiffness due to its advantages of light weight, simple and quick actuation. In our design, the compliant backbone of the fingers is made of 3d printed PLA material. Four thin film materials are attached to each side of the skeleton. The working process of the robotic gripper follows two basic steps. First, the compliant skeleton is bent to a desired shape by actuating a tension cable via a servo motor. Second, upon application of a negative pressure by a vacuum pump, the finger is stiffened up owing to the increasing of the friction between contact surfaces of layers preventing their relative movement. Since the structural stiffness of the fingers is increased, their load capacity will be increased proportionally. When the air pressure is sufficiently large, the morphed shape can even be locked (no slipping). Test for stiffness of individual finger and load capacity of the robotic gripper are conducted to validate capability of the design. The results showed a 69-fold increase in stiffness of individual finger and a 30-fold increase in gripper’s load capacity.","url":"https://doi.org/10.1115/detc2019-98294","authors":["Yuan Gao","Xiguang Huang","Ishan Singh Mann","Hai-Jun Su"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-11-25T16:55:21Z","doi":"10.1115/detc2019-98294","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1108/09576060210442978","name":"Robotic grasping: gripper designs, control methods and grasp configurations – a review of research","source":"crossref","abstract":"The application of robots to industrial problems often requires grasping and manipulation of the work piece.

When deployed on low-cost edge devices, traditional sorting robotic grippers have shortcomings such as insufficient gripper parameter output and weak sensing feedback. To address these problems, this paper proposes a design method for intelligent sorting robotic grippers based on lightweight image recognition and sensor fusion. To improve the safety of classification for mechanical operations, this paper introduces a Hardware-aware Loss function, which applies weighted penalties to the loss according to cross-bin misclassification, gripper width difference and clamping force difference, so as to reduce the risks of mis-sorting and improper grasping. The overall system structure includes a vision module, a sensing module, a decision-making module and an execution module. The sensing module uses low-cost sensors to measure object area/contour ratio, stiffness and mass features, and fuses them with image features to realize intelligent sorting decisions. Experiments are conducted on Fashion-MNIST and synthetic datasets for validation. The results show that the proposed method achieves high-accuracy object classification and gripper parameter prediction while maintaining lightweight performance, and can effectively support the practical application of low-cost intelligent sorting robotic grippers.

One‐way SMPs require reprogramming for each cycle, whereas two‐way SMPs (2W‐SMP) intrinsically exhibit shape memory behavior without additional programming. This study develops a cross‐linked polycaprolactone/dicumyl peroxide (PCL/DCP) based 2W‐SMP composite. The thermomechanical and thermal properties are characterized using dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). To create a freestanding 2W‐SMP capable of shape change and recovery solely through temperature variations, without relying on external loads for actuation, the SMP is embedded in a low‐stiffness elastomeric matrix. The resulting composite material exhibits an intrinsic two‐way shape memory effect, enabling reversible shape transformations during heating and cooling cycles. The one‐way and two‐way shape memory behaviors are systematically investigated using DMA. The one‐way shape memory effect demonstrated exceptional shape fixity and strain recovery values of 96% and 96.8%, respectively, confirming the material's ability to fix a temporary shape and recover its permanent form upon external stimulus. The practical potential of the 2W‐SMP is demonstrated by testing it as a gripper device, which exhibited repeatable opening and closing responses during heating and cooling cycles, illustrating its reversible shape transformations and durability over multiple actuation cycles.","url":"https://doi.org/10.1002/admt.202500614","authors":["Aamna Hameed","Kamran Ahmed Khan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-30T10:18:06Z","doi":"10.1002/admt.202500614","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1109/iros.2013.6697148","name":"Delicate grasping by robotic gripper with incompressible fluid-based deformable fingertips","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros.2013.6697148","authors":["Ryoji Maruyama","Tetsuyou Watanabe","Masahiro Uchida"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-01-06T17:10:53Z","doi":"10.1109/iros.2013.6697148","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1109/lra.2024.3357028","name":"G.O.G: A Versatile Gripper-on-Gripper Design for Bimanual Cloth Manipulation With a Single Robotic Arm","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3357028","authors":["Dongmyoung Lee","Wei Chen","Xiaoshuai Chen","Nicolas Rojas"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-01-22T18:46:53Z","doi":"10.1109/lra.2024.3357028","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.20295/1815-588x-2026-1-172-179","name":"Dynamic analysis of a robotic manipulator gripper","source":"crossref","abstract":"Objective: to identify and analyze the main transmission characteristics of a typical linkage mechanism used in the gripper of a robotic manipulator. Methods: the mechanism was investigated kinematically through both analytical and combined graphical-analytical analysis. Its dynamic behaviour was also evaluated under static conditions based on the principle of virtual velocities. In addition, a general equation of the mechanism’s dynamics was derived for motion involving rotation around the principal central axis of inertia. Results: relationships between the mechanism's transmission characteristics and its geometric parameters have been determined. The dependence of the permissible pressure angle in the mechanism's translational kinematic pair on the geometric parameters of the mechanism's configuration has been established. A functional relationship has also been obtained between the gripping force of the gripper and the force exerted on the hydraulic cylinder rod. Practical significance: the results of the kinematic analysis may be applied to synthesize a more advanced mechanism based on the criterion of permissible pressure angles. The findings can likewise support a more precise evaluation of the interaction between the gripper and the object being manipulated. The results of the force calculation are applicable to determining the parameters of the hydraulic power cylinder required to satisfy the robot’s specified load-carrying capacity.","url":"https://doi.org/10.20295/1815-588x-2026-1-172-179","authors":["Ekaterina Oparina"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-02T19:00:07Z","doi":"10.20295/1815-588x-2026-1-172-179","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1109/aim46323.2023.10196242","name":"Compliant finray-effect gripper for high-speed robotic assembly of electrical components","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim46323.2023.10196242","authors":["Richard Matthias Hartisch","Kevin Haninger"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-02T17:35:59Z","doi":"10.1109/aim46323.2023.10196242","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1016/s1474-6670(17)38379-9","name":"Design of a Three-Finger Gripper for Intra-Vehicular Robotic Manipulation","source":"crossref","abstract":"","url":"https://doi.org/10.1016/s1474-6670(17)38379-9","authors":["C.

The World Economic Forum (WEF) pointed out in “The Future of Jobs Report 2018” that the world is experiencing a “workplace revolution”, which means that machine will play a more important role in the future. In response to this situation, in this paper, techniques for object recognition and tracking on a conveyor using eye-in-hand gripper are presented, which are useful in production line for automatic object classification. The eye-in-hand configuration is the most suitable for camera and gripper application because the camera coordinate is the same as the gripper coordinate. The main advantages of eye-in-hand configuration are as follow: (1) occlusion avoidance (2) intuitive teleoperation (3) image from different angles (4) simple calibration. The main difference with eye-on-hand configuration is that it may be out of view sight when the camera is too close to the object. The experimental result is using the eye-in-hand robotic gripper to establish a tracking system to chase the target object. Preliminary results show that the speed of the conveyor can be calculated and the moving distance between the robot and the object is very close after a period of time. It means that the tracking system is successful.","url":"https://doi.org/10.1115/isps2019-7496","authors":["Shih-Wei Liu","Jen-Yuan (James) Chang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-11-25T22:02:17Z","doi":"10.1115/isps2019-7496","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1109/lra.2024.3414248/mm1","name":"A Soft Robotic Gripper with a Belt Loop Actuated Adhesion Design for Gentle Handling of Fragile Object_supp1-3414248.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2024.3414248/mm1","authors":["Gen Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-14T13:42:47Z","doi":"10.1109/lra.2024.3414248/mm1","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.2139/ssrn.6759656","name":"Enhancing Approach Adaptability in Robotic Grasping: Simulation-to-Experiment Validation of a Radial Slider-Crank Gripper","source":"crossref","abstract":"Achieving robust fingertip grasping in unstructured environments is challenging, as constraints on the manipulator&amp;apos;s approach direction necessitate the gripper to actively adapt its configuration to the object&amp;apos;s shape and pose. This study proposes a systematic, simulation-driven methodology to derive and implement a highly adaptable, three-fingered robotic gripper capable of mitigating these constraints. The optimal kinematic topology was selected through a comprehensive grasping simulation that quantifies the probability of the synthesized degrees of freedom (DOFs) effectively reaching diverse stable grasp candidate points, thereby optimizing for maximum fingertip adaptability. To realize this topology, a novel radial slider-crank mechanism is introduced, enabling dynamic control over both palm size and the lateral finger arrangement. Experimental validation compared the proposed variable palm against a fixed palm model using standard geometric objects (spheres, cylinders, and cuboids). The success rates measured across constrained approach angles (0 and 45 degrees) confirm that the variable palm mechanism significantly enhances pose adaptability for optimal grasping performance.","url":"https://doi.org/10.2139/ssrn.6759656","authors":["Geonbeom Lee","Young Min Lee","Sungwoo Park","Donghyun Hwang","Yong Seok Ihn"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-13T17:46:38Z","doi":"10.2139/ssrn.6759656","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.5958/2455-7110.2017.00010.6","name":"Study of the construction and working principle of tendon type multi fingered robotic gripper","source":"crossref","abstract":"It is proposed to study the construction and working principle of Tendon type multi fingered Robotic gripper.

One end of the tendons is wound about the low flanged cylinder whereas the other end is hinged to the finger tip. The low flanged cylinder is coupled to a geared D.C. Motor. Each revolute joint of the finger and thumb has a pulley over which the tensioning and loosening tendon is mounted in opposite directions. Each finger has three revolute joints and thumb has two revolute joint. The gripper can perform the basic function of picking, holding and grasping of objects. The tendoning of the revolute joints mechanism is such that it provides the gripper the ability to conform to the object topology.","url":"https://doi.org/10.5958/2455-7110.2017.00010.6","authors":["Zillur Rehman","R.A.

Industrial robots are involved in machining, the transfer of parts, control and assembly, and the number of tasks performed by robots are increasing. Robots need to have the capability to adapt to new jobs consisting of new parts and new trajectories, and in most cases the preferred end effectors are grippers. In turn, grippers need to be flexible enough in order to cope with these changes. For this research, the authors propose a new gripper design which is capable of handling a large variety of parts with different sizes and shapes. In this research, an electrically actuated four-jaw gripper, with the capability of parallel movement of its jaws, is presented that also has the capability to fold the clamping jaws two by two and become a two-jaw gripper. Since the design is most suitable for additive manufacturing techniques, different additive techniques are analyzed for the manufacturing of the gripper. In the second part of the paper, different setups of the 3D printers are considered, such as infill percentage, raster angle and layer height. The main material on focus is a PET with grinded carbon-fiber reinforcement, but different materials are used for a better comparison of the rigidity of the system. This comparison is also presented in this article. The analysis of the material and 3D printing parameters are tested with Standard D638-14 probes used in a traction testing machine. After performing the traction test, the results are compared with FEA analysis. An optimal solution based on the experimental tests is proposed for the manufacture of the proposed gripper design.","url":"https://doi.org/10.3390/machines11060621","authors":["Emilian Paduraru","Catalin-Gabriel Dumitras","Dragos-Florin Chitariu","Mihaita Horodinca","Florin Chifan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-06-05T02:57:47Z","doi":"10.3390/machines11060621","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1109/lra.2026.3719224/mm1","name":"Design and Control of a Monolithically Integrated Robotic Arm and Gripper Using Spatially Varying Hybrid Braided Structures_supp1-3719224.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2026.3719224/mm1","authors":["Zufeng Shang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-03T19:16:40Z","doi":"10.1109/lra.2026.3719224/mm1","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.121Z"},{"id":"doi:10.1109/robot.2003.1241610","name":"A thermally actuated polymer micro robotic gripper for manipulation of biological cells","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.2003.1241610","authors":["Ho-Yin Chan","W.J.

The proposed robotic arm and gripper explore new areas focusing on increasing the grasping performance of the gripper as well as the workspace. The gripper is designed with 3 fingers and driven by tendons using two servo motors. The tension of the strings is adjusted using a pulley mechanism and a string. The opening and grasping of the soft gripper are accomplished by each motor. The wide opening allows the gripper to grasp larger objects. The parallel robotic arm motion is actuated using 4 motors. These motors are mounted on a spherical shoulder plate with attached circular plates with angled axles are. The axles are angled so that their axes of rotation converge to the center point of the shoulder plate. The vertical and lateral motion of the robotic arm is controlled by the series of radial linkages connected to the motors, with a parallel linkage attached to the radial linkages to actuate the forearm of the mechanism. The robotic arm is 3D printed in polylactic acid (PLA) and the monolithic soft gripper is 3D printed in thermoplastic polyurethane (TPU). The gripping force applied by the gripper is obtained using flexible sensors attached to the tip of the 3 fingers. The finite element analysis is performed in SoldWorks and the link lengths are optimized to trace the desired workspace. The mechanism is tested for its grasping and lifting of various objects showing promising superiorities in terms of its grasping capabilities mimicking the human hand. If the robotic arm is mounted on a moving platform, then it can serve as an assistive robot for the elderly.","url":"https://doi.org/10.1115/imece2021-69880","authors":["Bryce Cianciotto","Derek Price","Logan Spencer","Martin Garcia","Ayse Tekes"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-01-25T22:04:10Z","doi":"10.1115/imece2021-69880","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/aris.2016.7886619","name":"Design of servo actuated robotic gripper using force control for range of objects","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aris.2016.7886619","authors":["Jin-Siang Shaw","Vipul Dubey"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-03-28T02:57:39Z","doi":"10.1109/aris.2016.7886619","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/coase.2019.8842987","name":"A Joint-Selective Robotic Gripper with Actuation Mode Switching","source":"crossref","abstract":"","url":"https://doi.org/10.1109/coase.2019.8842987","authors":["Katharina Hermann","Rafael Hostettler","Markus Zimmermann","Anand Vazhapilli Sureshbabu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-09-20T00:08:11Z","doi":"10.1109/coase.2019.8842987","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/tase.2023.3312296/mm1","name":"Design and Development of a New Bioinspired Hybrid Robotic Gripper for Multi-Mode Robust Grasping_supp2-3312296.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tase.2023.3312296/mm1","authors":["Qingsong Xu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-09-14T14:07:38Z","doi":"10.1109/tase.2023.3312296/mm1","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/smc.2019.8914479","name":"Design of a Soft Robotic Gripper for Improved Grasping with Suction Cups","source":"crossref","abstract":"","url":"https://doi.org/10.1109/smc.2019.8914479","authors":["Patrick Bryan","Shitij Kumar","Ferat Sahin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-11-29T15:09:34Z","doi":"10.1109/smc.2019.8914479","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/isec57711.2023.10402156","name":"Adjustable Platform for Exploring Soft Robotic Gripper Design","source":"crossref","abstract":"","url":"https://doi.org/10.1109/isec57711.2023.10402156","authors":["Janelle P.

Firstly, we describe the theoretical studies that have been investigated in order to optimally dimension these structures. For the bending joint, the design has been inspired from the literature and optimized. For the gripper, a non-intuitive design has been generated using a multi-objective optimal synthesis method. Finally, these compliant structures have been prototyped, and characterized. As an applicative example, they have been integrated into the end-effector of a surgical instrument.

This study proposed a novel layer-jamming mechanism of tuning the stiffness of soft grippers to increase its weight capacity. The study also proposed a novel bellowed-pipe structure for soft grippers to incorporate dual-mode gripping. The process of gripping was automated through the introduction of a camera and recognition algorithms capable of computing the size and depth of the detected object. Experiments conducted in room conditions, using the variable stiffness mechanism, the gripper could grip objects 120% heavier than without using the mechanism, indicating a significant advancement from traditional soft grippers.

The combination of rigid and soft structures is one of the methods to improve the performance of soft grippers. Grasping motion is achieved by the rigid structure of the screw and the connecting rod. Soft gripper uses human finger-like structure made of silicone, and the air pressure and the rigidity of the soft fingers can be adjusted by the air pump. The soft gripper overcomes the inability of a rigid gripper to easily and safely grasp soft and brittle objects and the inability of a completely soft gripper to exert sufficiently high forces to achieve effective grasping. Grasping force can be improved by increasing the stiffness of the finger and the driving stroke of screw. The variable grasping force allows the soft gripper to grasp different shape objects, specially soft and brittle objects.","url":"https://doi.org/10.1177/1729881419879824","authors":["Zhijie Tang","Jiaqi Lu","Zhen Wang","Gaoqian Ma"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-10-14T22:57:32Z","doi":"10.1177/1729881419879824","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/icar53236.2021.9659408","name":"A single-chip multimodal tactile sensor for a robotic gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icar53236.2021.9659408","authors":["Gorkem Anil AL","Bilal El Achab Oussallam","Uriel Martinez-Hernandez"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-01-05T15:42:02Z","doi":"10.1109/icar53236.2021.9659408","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/care.2013.6733715","name":"Intuitive control of three fingers robotic Gripper with a Data hand glove","source":"crossref","abstract":"","url":"https://doi.org/10.1109/care.2013.6733715","authors":["Meher Tabassum","D.

In situations involving danger or life-threatening conditions, it is safer to deploy robots instead of humans. However, there are still numerous applications where human intervention remains indispensable. The strategy to control a robot can be developed based on intelligent adaptive programmed algorithms or by harnessing the physiological signals of the robot operator, such as body movements, brain EEG, and muscle EMG which is a more intuitive approach. This study focuses on creating a control platform for a 3-finger gripper, utilizing Electromyography (EMG) signals derived from the operator’s forearm muscles. The developed platform consisted of a Robotiq three-finger gripper, a Delsys Trigno wireless EMG, as well as an NI CompactRIO data acquisition platform. The control process was developed using NI LabVIEW software, which extracts, processes, and analyzes the EMG signals, which are subsequently transformed into control signals to operate the robotic gripper in real-time. The system operates by transmitting the EMG signals from the operator's forearm muscles to the robotic gripper once they surpass a user-defined threshold. To evaluate the system's performance, a comprehensive set of regressive tests was conducted on the forearm muscles of three different operators based on four distinct case scenarios. Despite of the gripper’s structural design weakness to perform pinching, however, the results demonstrated an impressive average success rate of 95% for tasks involving the opening and closing of the gripper to perform grasping. This success rate was consistent across scenarios that included alterations to the scissor configuration of the gripper.","url":"https://doi.org/10.1007/s10846-024-02160-w","authors":["Aleksandra Loskutova","Daniel Roozbahani","Marjan Alizadeh","Heikki Handroos"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-09-13T09:02:58Z","doi":"10.1007/s10846-024-02160-w","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1177/17298806251337635","name":"Electroadhesion-enhanced pneumatic soft gripper for multimode and delicate grasping","source":"crossref","abstract":"This study addresses the limitations of conventional pneumatic soft grippers—restricted grasping versatility and compromised stability when handling irregular/massive objects due to insufficient structural stiffness—by proposing an electroadhesion-enhanced dual-pneumatic network (EDP) gripper.

The research was conducted in the Federal Scientific Agroengineering Center VIM from 2020 to 2023. The developed device is equipped with specialized mechanisms and sensors designed to reduce the negative eff ects on apples during harvesting. The study aims to justify the parameters of the robotic device for apple fruit picking and to conduct laboratory experimental studies of the grip strength eff ect on fruit damage during robotic fruit harvesting. A classification of gripping devices was developed based on the analysis of their design parameters and types. A concentric three-fingered gripper tool with rotating and sliding elements added to the gripping device was selected as the prototype device. As a result of studying the size and weight parameters of apples of the ‘Jonathan’ and ‘Granny Smith’ cultivars, data were obtained that enable one to describe the characteristics of these fruits more fully. Th e grapho-analytical method was employed to select the optimal geometric parameters of the gripper claws. We designed a robotic gripper which has several components, including gripper claws and a movable base. A laboratory setup was developed to simulate the operation of the manipulator and conduct experiments. Th e setup makes it possible to create conditions close to the actual manipulator operation and study the processes of grasping and holding fruits. The three-factor experiment allowed us to analyze the impact of the grip strength of the gripper claws, as well as the distance from the fruit to the gripper on the damage to fruits. It has been determined that these parameters have a signifi cant eff ect on the process of grasping and holding fruits. Entirely optimal values of these parameters contribute to reliable holding of a fruit in the gripper claws with minimal damage. As a result of analyzing the size-mass parameters of fruits, we found the average size and weight of apples of the Jonathan and Granny Smith cultivars. Th e design parameters of the robotic device were justifi ed. A 3D robotic gripper model was developed. We also manufactured an experimental robotic gripper model which underwent laboratory tests. As a result, the parameters of the grip strength and the distance from the fruit to the gripper were identified.","url":"https://doi.org/10.31676/0235-2591-2024-1-40-50","authors":["D. S. Pupin","D.

Relying on the physical properties of the fabricated materials, the unplugged robotic gripper can be powered by ambient energy sources such as water, heat, and light, which distinguishes it from conventional robotic grippers driven by electric or pneumatic energy. Consequently, energy storage devices and hardware driving circuits are no longer required, which effectively reduces the risk of electric leakage. In this study, an unplugged robotic gripper was developed using the 4D printed hydrogel, which aimed to perform grasping tasks underwater without electrical motors and waterproof devices. The surrounding water in underwater environments could be directly used as its power source, and the grasping force was generated through the expansion of the 4D printed hydrogel. The physical parameters of the unplugged robotic gripper such as deformation, Young’s modulus and static friction coefficient, were experimentally calibrated.A method to estimate the grasping force was proposed using these calibrated physical parameters, and the time required for stable grasping could be predicted. Experimental verification was implemented to evaluate the gripper’s grasping capability. A variety of target objects including seashell, conch, pearl and coral sample could be stably grasped underwater using the developed gripper prototype.","url":"https://doi.org/10.2139/ssrn.7316723","authors":["Zhe Qiu","Yitong Xue","Kusuma  Betha Cahaya Imani","Hidemitsu Furukawa","Yang Tian","Shinichi Hirai","Lijuan Li","Zhongkui Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-20T00:37:26Z","doi":"10.2139/ssrn.7316723","addedAt":"2026-08-31T06:34:15.834Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1115/detc2014-35245","name":"High Reconfigurable Robotic Gripper for Flexible Assembly","source":"crossref","abstract":"This paper describes a general purpose gripper to be used into industrial manufacturing application.

The patterned surface functions as a visual encoding layer, where applied forces induce measurable, direction-dependent shifts in reflected color distribution. By deploying multiple color sensors in an array, each sensor captures localized color variations, enabling spatial reconstruction of both magnitude and direction of applied loads through differential color analysis. The sensor's performance was validated through robotic gripper integration, where it successfully provided multi-axis force feedback and enabled adaptive gripping force adjustment to achieve robust and stable object manipulation. The experimental results confirm the system's ability to effectively sensing 3D forces and torsion forces, and support closed-loop control in adaptive robotic grasping.

Here, we present a thin, compact, and compliant optical tactile sensor with an alignment-free architecture. The proposed sensor captures deformation-induced variations in speckle patterns generated within a soft silicone medium, from which tactile information is inferred using a data-driven model. Experiments demonstrate a spatial resolution better than 20 &#xb5; m and a force measurement precision below 40 mN. Notably, contact position, applied force, and ambient temperature are simultaneously estimated from a single speckle observation, demonstrating inherent multimodal sensing capabilities and robustness to thermal drift. To validate its practical utility, we integrate the sensor into a robotic gripper, achieving classification of nine engraved surface patterns with an accuracy of 93.33 % .

In this study, we focused on the automation of raw-oyster handling which can be achieved by a robotic system equipped with a soft robotic gripper. However, raw oysters are fragile and prone to large damage during robotic handling, while high-speed handling generates inertial effects. Minimizing the grasping force is thus essential to protect raw oysters, while preserving the grasping stability is required. To address, this study introduces and validates a robotic system equipped with a soft pneumatic gripper for raw-oyster handling task in food production lines. Finite element analysis (FEA) was employed to discuss the effect of gripper actuation pressure on finger deflection and gripper grasping force, revealing a trade-off: increasing actuation pressure improves stability but raises grasping force, whereas reducing actuation pressure causes excessive swing and tossing problems. An optimal actuation pressure of the soft gripper was identified as grasping stability and oyster integrity, minimizing swing while preventing excessive grasping force. Handling performance of the robotic system was experimentally evaluated with raw oysters under different actuation pressures and oyster orientations. Under the optimal actuation pressure confirmed in FEA, the robotic system achieved a handling success rate of 100% (15/15) without obvious misalignment and large damage of raw oysters, which confirmed its adaptability for high-speed, stable handling. This study offers a reference of robotic systems for handling fragile aquatic products and indicates that optimal actuation pressure can protect such products during robotic handling, thereby facilitating the automation of aquatic product processing.","url":"https://doi.org/10.3390/foods14162875","authors":["Yang Zhang","Zhongkui Wang"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/foods14162875","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.21203/rs.3.rs-8672329/v1","name":"Robotic Deconstruction of Brickwork Enabled by Spatial Artificial Intelligence","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-8672329/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-8672329/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.21203/rs.3.rs-8491477/v1","name":"A Novel Approach to Tomato Harvesting Using a Hybrid Gripper with Semantic Segmentation and Keypoint Detection","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-8491477/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-8491477/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.3390/s26134079","name":"simDP: Sim-to-Real Transfer with Shared Action Spaces.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26134079","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26134079","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.1002/adma.73528","name":"Fish-Scale-Inspired Giant Piezocapacitive Sensors for Human-Level Touch Perception.","source":"pubmed","abstract":"Achieving human-level touch perception in robotics requires flexible sensors that combine a low detection limit, rapid response, robust reliability, and ease of fabrication. Yet, integrating these diverse characteristics into a single device remains a formidable challenge. This work presents a giant piezocapacitive sensor (GPCS) that matches human touch perception capabilities, based on a fish-scale-inspired electric-field gating film. This mechanically compliant and robust biomimetic film consists of high-permittivity rigid scales separated by air gaps within an elastomer matrix, resulting in a high bulk permittivity. These gaps act as electric-field gates that modulate the fringing electric field between electrode pairs, translating subtle mechanical deformations into substantial capacitance changes. Consequently, the GPCS achieves an exceptional bidirectional bending resolution of 0.005&#xb0; over a range of &#xb1;&#xa0;90&#xb0; with a response time of 0.6&#xa0;ms, showing no performance degradation in a 100&#xa0;000-cycle bending test. This performance enables the precise discrimination of 16 fabric textures and the detection of surface topographies as fine as 1.8 &#xb5;m-sufficient to resolve printed toner lines on paper. Finally, a GPCS array is integrated onto a robotic gripper, demonstrating in situ ripeness evaluation of kiwis during grasping, automated fruit sorting, and intuitive human-robot interactions.","url":"https://doi.org/10.1002/adma.73528","authors":["Peng Y","Li Z","Zhang J","Wang Y","Wang S","Wu H","Wang H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/adma.73528","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.3390/s25206496","name":"A Dexterous Reorientation Strategy for Precision Picking of Large Thin Objects.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25206496","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25206496","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s26020724","name":"Enhancing Robotic Grasping Detection Using Visual-Tactile Fusion Perception.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26020724","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26020724","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/smll.74747","name":"Material Extrusion-Enabled Soft Multimodal Pressure Sensors With Fabrication-Embedded Stretch-Induced Strain Insensitivity.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/smll.74747","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/smll.74747","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/s26113506","name":"Multimodal PCSC Sensors for Real-Time Temperature and Force Detection Using LRTNet.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26113506","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26113506","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s25195978","name":"Digital Twin-Based Intelligent Monitoring System for Robotic Wiring Process.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25195978","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25195978","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.34133/research.0737","name":"Instant Energy Barrier Modulation in Bistable Robotic Grippers for Compliant Triggering and Powerful Grasping.","source":"europepmc","abstract":"","url":"https://doi.org/10.34133/research.0737","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.34133/research.0737","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.21203/rs.3.rs-9133026/v1","name":"Underwater dielectric elastomer actuators with large bending deformation for soft robots","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-9133026/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-9133026/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1177/21695172251400144","name":"Everything-Grasping Gripper: A Universal Gripper with Synergistic Suction-Grasping Capabilities for Cross-Scale and Cross-State Manipulation.","source":"europepmc","abstract":"Grasping objects across vastly different sizes and physical states-including both solids and liquids-with a single robotic gripper remain a fundamental challenge in soft robotics. We present the Everything-Grasping (EG) Gripper, a soft end-effector that synergistically integrates distributed surface suction with internal granular jamming, enabling cross-scale and cross-state manipulation without requiring airtight sealing at the contact interface with target objects. The EG Gripper can handle objects with surface areas ranging from submillimeter scale 0.2 mm 2 (glass bead) to over 62,000 mm 2 (A4-sized paper and woven bag), enabling manipulation of objects nearly 3500× smaller and 88× larger than its own contact area (approximated at 707 mm 2 for a 30 mm diameter base). We further introduce a tactile sensing framework that combines liquid detection and pressure-based suction feedback, enabling real-time differentiation between solid and liquid targets. Guided by the Tactile-Inferred Grasping Mode Selection algorithm, the gripper autonomously selects grasping modes based on distributed pressure and voltage signals. Experiments across diverse tasks-including underwater grasping, fragile object handling, and liquid capture-demonstrate robust and repeatable performance. To our knowledge, this is the first soft gripper to reliably grasp both solid and liquid objects across scales using a unified compliant architecture.","url":"https://doi.org/10.1177/21695172251400144","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1177/21695172251400144","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.1073/pnas.2519693122","name":"Multisensory electronic skin with decoupled pressure-temperature-sensing capabilities for similar object recognition.","source":"europepmc","abstract":"","url":"https://doi.org/10.1073/pnas.2519693122","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1073/pnas.2519693122","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/polym18070891","name":"Tribomechanical Behaviour and Elasto-Plastic Contact Response of 3D-Printed Versus Conventional Polymer Inserts in Robotic Gripping Interfaces.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/polym18070891","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/polym18070891","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3389/frobt.2025.1598296","name":"Error recovery in wearable robotic Co-Grasping: the role of human-led correction.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1598296","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1598296","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.3390/s26020645","name":"Real-Time Target-Oriented Grasping Framework for Resource-Constrained Robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26020645","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26020645","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/polym17182464","name":"Polymers as the Primary Fabrication Material for Soft Robotic Grippers: A Concise Review.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/polym17182464","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/polym17182464","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1038/s44182-025-00055-y","name":"Let's DENSE: a novel protocol for efficiently collecting dense and diverse data for tactile slip detection in robotic grasping.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s44182-025-00055-y","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s44182-025-00055-y","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1038/s41467-025-67148-y","name":"Flexible robotic hand harnesses large deformations for full-coverage human-like multimodal haptic perception.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-67148-y","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-67148-y","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s25185782","name":"Construction and Experimental Analysis of a Multipurpose Robotic Fin Ray Gripper for Manipulator Robots.","source":"europepmc","abstract":"This article presents a methodology for estimating the gripping forces in a Fin Ray-type gripper, based on the integration of experimental and computational approaches.

Additionally, we show that optimized RCJs increase the load-carrying capacity of a two-finger gripper by more than 3.5 times compared to a comparable circular-jointed design, showcasing how joint optimization can enhance robotic performance.","url":"https://doi.org/10.1073/pnas.2521406123","authors":["Decker CJ","Chen TG","Yuen MC","Wood RJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1073/pnas.2521406123","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/s26123810","name":"Modular Framework for Responsive and Explainable Robotic Assistance with Intention Prediction Using Human-Centric Digital Twins.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26123810","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26123810","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3389/frobt.2025.1660244","name":"Visuo-tactile feedback policies for terminal assembly facilitated by reinforcement learning.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1660244","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1660244","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.3390/biomimetics10120813","name":"Design and Sensing Frameworks of Soft Octopus-Inspired Grippers Toward Artificial Intelligence.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10120813","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10120813","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/adma.202508795","name":"Machine Learning-Enhanced Modular Ionic Skin for Broad-Spectrum Multimodal Discriminability in Bidirectional Human-Robot Interaction.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/adma.202508795","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/adma.202508795","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:31.458Z"},{"id":"doi:10.3389/frobt.2026.1697561","name":"Collapse and collision aware grasping for cluttered shelf picking.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2026.1697561","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1697561","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1038/s41467-025-65479-4","name":"Stiffening iron particles to modulate physical interactions.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-65479-4","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-65479-4","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.34133/research.1174","name":"Integrated 3D Printing of Liquid Metal and Elastomer for Soft Robots and Electronics.","source":"pubmed","abstract":"Soft robots and stretchable electronics, typically composed of stretchable elastomers and embedded conductive coils, have been widely investigated for applications in actuation, sensing, and communication.

Here, we present a multimaterial 3-dimensional (3D) printing strategy based on direct ink writing technology, which enables the one-step fabrication of stretchable elastomers embedded with high-conductivity multilayer coils. This is achieved by alternately printing elastomer and nickel-particle-modified liquid metal (NLM) coil layers in a program-controlled sequence, with vertically printed NLM cones connecting adjacent NLM layers. With this strategy, we achieved one-step fabrication of a 4-layer-coil soft electromagnetic actuator (SEMA) and a self-sensing SEMA integrating sensing and driving modules, without the need for manual bonding or post-processing. We further built 3 functional devices to show the potential applications of this integrated 3D printing strategy: a sensor-integrated soft gripper capable of perceiving its own grasping state, a bio-inspired manta-like soft electromagnetic robot that achieves a swimming speed of 29 mm/s, and a SEMA integrated with a Hall sensor and a red light-emitting diode, which exhibits strong mechanical robustness.

While visual information is usually provided in any master-slave system, haptic perception is often missing. Despite the importance of the sense of touch while performing surgical procedures, minimally invasive robotic surgery still lacks the reproduction of haptic stimuli at the master side, mostly due to the difficulties in measuring forces at the contact site. However, there could be also procedures in open surgery in which a reduction of the natural haptic perception may occur, for example because vibrations generated by the surgical tool affect the surgeon?s perception. This thesis addresses the challenge of measuring forces between surgical instruments and patient?s tissues both in robotic and open surgery, presenting innovative pneumatic force sensors that rely on pressure variations inside one or more chambers. Performance comparisons with accurate commercial force sensors proved the feasibility and effectiveness of the proposed approaches. Besides, many advantages can be appreciated in terms of size, cost, biocompatibility, possibility of changing sensor features such as stiffness according to the application, and absence of electronic components into the patient?s body. The achieved results paved the way towards the exploitation of novel pneumatic-based devices for contact detection in more general robotic manipulation scenarios. In this context, a pneumatic device has been proposed to create soft inclusions in the environment that can be used by rigid grippers to achieve safer grasps. The use of soft sensing modules allows us to detect the contact between the gripper and the environment during grasp approach, and to estimate the approximate location and weight distribution of the object to be grasped. A system that combines the precision of rigid grippers with the adaptability of pneumatic-based devices was developed and successfully tested in grasping tasks with several different objects, taking advantage of the strengths of both rigid and soft robotics approaches.","url":"https://doi.org/10.25434/gaudeni-chiara_phd2021","authors":["Gaudeni, Chiara"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.25434/gaudeni-chiara_phd2021","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.17632/jrvww6fjvj.1","name":"Mechanism and Experimental Study of Multi-mode Vibration-based Gradual Separation of Bare-root Paeonia lactiflora var. rubra Seedlings","source":"datacite","abstract":"This link contains the simulation tutorial, vibratory seedling separation, robotic gripper grasping, seedling‑rolling videos, international novelty search report, and performance test report.","url":"https://doi.org/10.17632/jrvww6fjvj.1","authors":["Liu, Zhengduo"],"tags":["Agricultural Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.17632/jrvww6fjvj.1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.17632/jrvww6fjvj","name":"Mechanism and Experimental Study of Multi-mode Vibration-based Gradual Separation of Bare-root Paeonia lactiflora var. rubra Seedlings","source":"datacite","abstract":"This link contains the simulation tutorial, vibratory seedling separation, robotic gripper grasping, seedling‑rolling videos, international novelty search report, and performance test report.","url":"https://doi.org/10.17632/jrvww6fjvj","authors":["Liu, Zhengduo"],"tags":["Agricultural Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.17632/jrvww6fjvj","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.48550/arxiv.2608.26883","name":"Active Surface-Driven Reconfigurable Gripper: Robust Grasping and Sequential Manipulation of Thin Objects","source":"datacite","abstract":"Robotic grippers face substantial challenges in grasping and manipulating thin objects. Most existing grippers rely on highly precise approach and grasp motions, which limits robustness and reduces applicability. This paper explores thin-object grasping using books as a representative example. Here, we propose a novel solution that integrates an active surface with underactuated compliance to achieve stable grasping of thin objects without complex control. First, an underactuated gripper with an active surface is designed. The active-surface thumb performs in-hand repositioning of the target book without requiring adjustments of the robot arm or the other fingers, while the underactuated fingers establish compliant contact conditions with the environment, and the reconfigurable structure enables reliable grasping of books under different configurations. Second, we establish a kinematic model of the gripper, and determine the initial grasp postures for two representative scenarios (books lying flat on a desktop and books vertically packed in a shelf). Third, by analyzing the physical model of a book lying on a table and its interaction with the gripper and the environment, we systematically optimize the structural parameters and grasping strategy. Finally, extensive experiments validate the effectiveness of the proposed gripper and strategy. The results demonstrate strong robustness and adaptability when grasping thin objects placed flat (including books, paper, fabric, plastic film, and mouse pad), as well as a high success rate when grasping vertically packed books. Moreover, the proposed gripper can reliably complete long sequential \"grasp-place\" tasks.","url":"https://doi.org/10.48550/arxiv.2608.26883","authors":["Zheng, Ziyi","Zhu, Keqi","Wu, Hao","Wang, Yanzhe","Dong, Huixu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.26883","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.48550/arxiv.2608.26622","name":"Relaxation-Aware Multimodal Sensing of Soft Gripper Driven by Structure-Perception-Learning","source":"datacite","abstract":"Achieving stable, sustained grasping with soft robotic hands remains a fundamental challenge. Compliance enables safe and adaptive contact, yet the intrinsic viscoelasticity of soft polymers leads to stress relaxation and a continuous decay of grasping force during holding.

We develop a variable-stiffness soft gripper that uses onboard vision and infrared thermography to track deformation and the temperature field in real time, preserving continuous tracking of the interaction state. To mitigate relaxation-induced force decay, we propose a temperature-coupled viscoelastic force representation, together with a physics-informed learning model, to reconstruct the force trend and provide explicit compensation during holding. Experiments show that, in a 280s force-controlled grasp-and-hold task, the proposed method maintains the desired force with a mean absolute error of 0.066N, outperforming fixed-aperture and instantaneous-only baselines by 80% and 95%, respectively.

Components size has then to be reduced as well, coming through micro- and then nanoscale. The industrial equipments dedicated to their fabrication and assembly have comparatively a huge size, but one observes now a new and welcome trend for reducing their overall dimensions. However the latest robotic technologies allow achieving nanometric resolution and precision of positioning. Microcomponents assembly is still yet badly controlled and many surprising effects can occur without understanding of the real phenomenon. In fact, below one millimeter size objects are becoming insensitive to gravity comparing to surface forces. The manipulation of such components needs new and innovative ways to control these forces and so on to allow the release. In this study pick and place operations have been analyzed with an adimensional parameter Γ. It represents the ratio of the forces that act at the \"object – gripper\" and \"object – target surface\" interface. The adhesion effect is then taken into account in a comparative manner. The advantage of such procedure is due to the large amount of uncontrolled or unknown parameters that are needed to evaluate the adhesive forces. The behaviors of the micro object during pick and place operations are then studied on the base of Γ. Characteristics allowing a reliable transfer can be extracted with focus on the ones that generate fewer disturbances on the position. Generalization of the models allows finally to study different manipulation principles. The conception of microgrippers needs to consider the adhesion effects. Thus a methodology is proposed. Its main point concerns the importance of a strong interaction between the designers of the different elements that are the component, the receiver and the gripper. In such a way optimal choices for the surfaces and principles of manipulation can be done. After having defined the main trends theoretically, the difficult evaluation of the adhesion effect in real conditions causes the need to check rapidly by experiments the feasibility of the pick&amp;place operations. A micromanipulation setup has been developed in order to make comparative tests between the different gripper principles. Gripper characterization means in particular the measurement of the positioning errors induced during the placing step. Several gripper families were conceived during this study: microtweezers, inertial gripper based on adhesion, capillary grippers that use the condensation/evaporation of the relative humidity, electrostatic grippers as well as vacuum gripper. Experiments were conducted with polystyrene spheres of ∅ 50µm. A high sensitivity to the alignment between finger tip or gripper tip and micro object was observed. It concerns in fact mainly the need to limit the force applied on the component during manipulation. The gripper withdrawal direction has also showed to be of the most importance to control the operations and their reliability. Finally robotic assembly of MEMS components was realized to get a 3D structure. The methodology was experimented on this application. The importance of a close interaction of the different designers has been demonstrated. We proposed here an approach as well as the models allowing studying the main trends with taking into account the adhesion forces. The whole arrangement of the contact areas as well as each force present during the operations is included into the models. The interfaces characteristics can so be analyzed. This allows defining the optimal strategy. This study is a tool for the designer of microassembly equipment. With the proposed methodology we hope or rather give the opportunity to stimulate integration or combination of innovative micromanipulation principles.","url":"https://doi.org/10.5075/epfl-thesis-4160","authors":["Dafflon, Mélanie"],"tags":["micromanipulation","microgripper","adhesion force","methodology of conception","microtweezers","inertial gripper","vacuum gripper","capillary gripper"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2008","doi":"10.5075/epfl-thesis-4160","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.5281/zenodo.19711122","name":"DESIGN AND SIMULATION BASED STRUCTURAL ANALYSIS OF A HUMAN INSPIRED TWO FINGER SOFT ROBOTIC GRIPPER","source":"datacite","abstract":"There is an emerging trend in using soft robotic grippers in applications that call for a safe and flexible manipulation of small and irregular-shaped objects.

While effective for latent-space planning, the representations learned by Raw LeWM are poorly suited for downstream robot policy learning. In this paper, through Monte Carlo analysis, we show that the Raw LeWM objective biases variance allocation toward the temporally persistent component, thereby suppressing the variance of the temporally centered residual. Consistent with this analysis, trained Raw LeWM representations exhibit suppressed residual variation and reduced decodability of robot state and dynamics, particularly gripper dynamics, which are crucial for robotic manipulation. To address this issue, we apply SIGReg to temporally centered residuals rather than to the whole latent representation. This simple change decouples persistent and residual variance allocation while retaining an effective anti-collapse property. On the LIBERO benchmark, our method improves downstream policy success on the Goal suite by 1.66x and raises the average success rate across all suites from 63.6% to 83.8%. Without external pretraining, it also outperforms both Diffusion Policy trained from scratch and the pretrained OpenVLA baseline.

Different gripper types, such as parallel-jaw and suction, usually require distinct interaction strategies to achieve the same grasping objective. Moreover, current datasets for VLAs predominantly rely on parallel-jaw grippers, limiting gripper-aware learning. To address this gap, we introduce MiGA, a multi-gripper-aware dataset spanning five distinct gripper types across multiple robots with 103,000 demonstrations, explicitly capturing strategy divergence under shared task objectives.

This framework combines whole-body bilateral teleoperation with an online multi-stage object inertial parameter estimation module, which is the core technical contribution of this work. The multi-stage process sequentially integrates a vision-based object size estimator, an initial parameter guess generated by a large vision-language model (VLM), and a decoupled hierarchical sampling strategy. The visual size estimate and VLM prior offer a strong initial guess of the object's inertial parameters, significantly reducing the search space for sampling-based refinement and improving the overall estimation speed. A hierarchical strategy first estimates mass and center of mass, then infers inertia from object size to ensure physically feasible parameters, while a decoupled multi-hypothesis scheme enhances robustness to VLM prior errors. Our estimator operates in parallel with high-fidelity simulation and hardware, enabling real-time online updates. The estimated parameters are then used to update the wheeled humanoid's equilibrium point, allowing the operator to focus more on locomotion and manipulation. This integration improves the haptic force feedback for dynamic synchronization, enabling more dynamic whole-body teleoperation. By compensating for object dynamics using the estimated parameters, the framework also improves manipulation tracking while preserving compliant behavior. We validate the system on a customized wheeled humanoid with a robotic gripper and human-machine interface, demonstrating real-time execution of lifting, delivering, and releasing tasks with a payload weighing approximately one-third of the robot's body weight.","url":"https://doi.org/10.48550/arxiv.2508.09846","authors":["Baek, Donghoon","Purushottam, Amartya","Choi, Jason J.","Ramos, Joao"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2508.09846","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.17632/sbfpyh3wyt.1","name":"data_two_soft_fingers_2026_8","source":"datacite","abstract":"Raw textile sensor signals (stretch and pressure sensors) from grasping trials of a soft robotic gripper 2026 Aug.","url":"https://doi.org/10.17632/sbfpyh3wyt.1","authors":["Vu, Chi Cuong"],"tags":["Machine Learning","Sensor","IoT Application","Soft Robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.17632/sbfpyh3wyt.1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.17632/sbfpyh3wyt","name":"data_two_soft_fingers_2026_8","source":"datacite","abstract":"Raw textile sensor signals (stretch and pressure sensors) from grasping trials of a soft robotic gripper 2026 Aug.","url":"https://doi.org/10.17632/sbfpyh3wyt","authors":["Vu, Chi Cuong"],"tags":["Machine Learning","Sensor","IoT Application","Soft Robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.17632/sbfpyh3wyt","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.48550/arxiv.2608.20962","name":"Hybrid Roller-Jamming Gripper for Object Acquisition and Retention Under Pose Uncertainty","source":"datacite","abstract":"In household manipulation, pose uncertainty often results in off-centre or partial initial contact, making reliable object acquisition difficult. Roller-based grippers can actively draw objects inward but often provide limited post-capture stability, whereas granular-jamming grippers require sufficient contact before jamming to achieve strong retention. This paper presents a hybrid roller-jamming gripper that integrates active object intake and post-capture retention within a single gripper. The proposed gripper uses inward roller rotation to increase contact and draw the object toward the gripper centre, followed by vacuum-induced granular jamming to stiffen the rollers and stabilise the grasp. The paper also presents a simplified geometric analysis of the gripper and a bench-level characterisation of the prototype's force capability. The gripper prototype was mounted on a 7-DoF robotic arm and evaluated using eight test objects. Furthermore, controlled planar position and orientation offsets were applied, with each condition repeated three times. The main evaluation comprised 840 grasp trials, including 216 planar-offset trials and 624 orientation-offset trials. Overall, the gripper succeeded in 812/840 trials: 215/216 planar-offset trials and 597/624 orientation-offset trials. The ablation evaluation comprised 162 trials on three objects. The roller-only and jamming-only conditions achieved 54/81 and 24/81 successes, respectively, showing their different contributions. These results provide initial mechanism-level evidence that hybrid roller-jamming is a promising strategy for improving acquisition and retention after imperfect first contact.","url":"https://doi.org/10.48550/arxiv.2608.20962","authors":["Ren, Yijie","Gourmelen, Guillaume","Iwata, Hiroyasu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.20962","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.48550/arxiv.2608.20546","name":"Koala Gripper: Co-designing Robotic Grippers and Data-Capture Devices for Scaling Dexterous Manipulation Learning","source":"datacite","abstract":"As the demand for larger manipulation datasets grows, handheld robotic gripper data collection and the associated gripper designs become more vital.

Through this workflow, we present the Koala Gripper system, a data capture device and robotic gripper platform that improves dexterity and grasp capability compared to parallel jaw grippers while preserving scalability and ease-of-use. The design introduces a novel force-optimized finger/trigger linkage mechanism with directional reflected mass characteristics, a unique monolithic dual-thumb, and user-centered ergonomic design. The design's actuated robotic fingers are backdrivable, with effective mass on the order of tens of grams. We show that these grippers are capable of secure grasps over a wide range of objects, forceful tool use, and precise singulation.

The dataset is instrumental in advancing safety systems and robotic aid in real-time scenarios within the field of machine learning, fostering the development of intelligent, reliable solutions for human-robot collaboration.&lt;/p&gt; &lt;img src=\"https://dataverse.tdl.org/api/access/datafile/299850\" alt=\"Preview for the Hand and Glove Segmentation Dataset\" width=\"500\" height=\"500\"&gt; &lt;p&gt; &lt;b&gt; Dataset Preview &lt;/b&gt; &lt;/p&gt; &lt;h1&gt;Dataset Characteristics&lt;/h1&gt; &lt;p&gt;As mentioned, the dataset captures two human-robot collaboration experiments. In the first experiment, participants built a Jenga block tower, receiving six blocks from the robot manipulator arm. The second experiment required participants to disassemble a box, with the robot manipulator arm providing the participant with different screwdrivers to remove four screws. Each participant repeated both experiments four times under the following conditions: a) wearing gloves, b) ungloved, c) with a green screen placed along the bottom of the glovebox, and d) without a green screen placed along the bottom. Lastly, each experiment was recorded from two distinct camera angles: a top view and a side view.&lt;/p&gt; &lt;h1&gt;Dataset Contents&lt;/h1&gt; &lt;p&gt;The dataset contains:&lt;/p&gt; &lt;ol&gt;&lt;li&gt; Ten participants conducted two experiments, each involving four variables and two camera angles, resulting in a total of 16 videos per participant.&lt;/li&gt; &lt;li&gt; Eight hours of video footage of each experiment.&lt;/li&gt; &lt;li&gt; 2876 annotated in-distribution and out-of-distribution frames.&lt;/li&gt; &lt;li&gt; 1438 original, unannotated sampled frames.&lt;/li&gt;&lt;/ol&gt; &lt;h1&gt;Data Collection&lt;/h1&gt; &lt;p&gt;The data was collected in a standard glovebox commonly utilized by researchers in the DOE. Each video provides two camera angles: one from a bird's eye view captured by a 1080p GoPro, and another from a 1080p Intel RealSense Development Kit Camera recording from the right side of the participant. To assist the participants, a Universal Robots UR3e robot manipulator arm equipped with a gripper for object handling was pre-programmed to conduct the two tasks. Two researchers assisted in the experiment, one operating the robot arm and the other assisting in object placement. The collection process ensured normally distributed frames from each video, which were then annotated.&lt;/p&gt; &lt;h1&gt;Data Post-Processing for Machine Learning&lt;/h1&gt; &lt;p&gt;For applications with machine learning, the sampled frames were split into two sets: a) in-distribution set and b) out-of-distribution set. The in-distribution set contains the most likely scenarios to occur with human-robot collaboration work in a glovebox, providing applicability in model training. Therefore, videos without a green screen in the background and with participants wearing gloves were designated as the in-distribution set. The rest of the videos contain either the participant not wearing gloves and/or a green screen placed in the background. These scenarios are less likely to occur in a glovebox setting, and thus related frames were placed in the out-of-distribution set, providing applicability in model evaluation. 1440 frames were sampled for labeling. These frames were sampled equally distributed across all the videos, with 120 in-distribution frame","url":"https://doi.org/10.18738/t8/85r7kq","authors":["Sharma, Shivansh","Huang, Mathew","Nair, Sanat","Wen, Alan","Petlowany, Christina","Wanna, Selma","Pryor, Mitch"],"tags":["Computer and Information Science","Engineering","Robotics","Glovebox","Human-Robot Collaboration","Machine Learning","Hand Segmentation","Semantic Segmentation"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.18738/t8/85r7kq","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.5281/zenodo.21560850","name":"Colour Sensing Using Robotic ARM","source":"datacite","abstract":"Robots are used in various industries to save the process flow in terms of time and ease.

We introduce a fundamentally different approach, grounded in the observation that the gripper and the object share identical surface geometry at their mutual contact points. We propose GOAG: Generative and Object-Agnostic Grasp Planner for Dexterous Robotic Manipulation, a novel deep generative model that learns a compact latent representation of a specific gripper's contact surface distribution, enabling the efficient sampling of valid grasp configurations without relying on object-specific training data. We show that by introducing object features only at inference time, our model can effectively retrieve admissible contact areas that are compatible with the gripper's capabilities. We validate our approach through extensive experiments on established grasp protocols in both simulated and real-world scenarios, demonstrating its effectiveness with different grippers from the literature. Our method delivers state-of-the-art results on the objects from the MultiDex dataset, achieving an average success rate of 86.93%. It offers significantly faster processing when generating numerous grasps, while matching the performance of leading approaches specifically trained on this dataset. Unlike these methods, our approach does not rely on object-specific training data, highlighting the advantages of object-agnostic learning.

This work proposes PartialBiGrasp, a dual-arm grasp generation framework that operates directly on partial point cloud observations. Our model learns geometric features implicitly through convolutional occupancy networks, enabling local reasoning about graspability, collision-free contact regions, and object thickness. We leverage this understanding to generate force-closure compliant grasp pairs, which are further refined using a sampling-based optimization to correct for ambiguity caused by incomplete geometry.

While prior work on robotic object throwing has largely focused on generating dynamically feasible release velocities using open-gripper paradigms, explicit control of spin injection at detachment remains underexplored, particularly for aerodynamically anisotropic objects like the American football. In this paper, we present the spin-stabilized controlled tight spiral throw of an American football by a humanoid robot. Achieving this requires (i) accurately reaching the desired coupled momentum, which often involves high degrees-of-freedom (DoF) movements completed within approximately half a second, and (ii) managing the complex transient contact dynamics that arise during the sub-100-millisecond release phase, when the football is effectively underactuated as it moves partially across the fingers. To this end, we develop a coupled whole-body control strategy where the lower body is performing informed stabilization while the upper body is further divided into two phases with (i) a throw phase accelerating the football to a target state through trajectory optimization and tracking, and (ii) a follow-through phase utilizing model predictive control to actively control the wrist and remaining in-contact fingers. The proposed framework is empirically validated on a 29-DoF Unitree G1 humanoid equipped with a 7-DoF Dex3-1 three-fingered gripper. The thrown American football reaches up to 93.6% spin efficiency and a 0.286 radians linear-velocity-to-nose-alignment (nose-angle) error (where an ``ideal'' tight spiral corresponds to 100 % spin efficiency and 0 radians nose-angle error) at up to a 5.35 m/s linear velocity and an angular velocity of 14.5 rad/s.","url":"https://doi.org/10.48550/arxiv.2608.16642","authors":["Mahboob, Zaid","Weng, Bowen"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.16642","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.48550/arxiv.2608.15968","name":"Tabletop Pen Manipulation With a Vision-Guided 4-DoF Arm","source":"datacite","abstract":"Low-cost four-degree-of-freedom (DoF) arms are among the most accessible robotic platforms. But they are, in theory, underactuated for picking up in situations where objects are at arbitrary orientations, a task that appears to require five degrees of freedom: the planar position (x and y), the height (z), a wrist rotation to align the gripper with the object, and gripper actuation, of which a four-DoF arm lacks the wrist rotation. This work shows that perception and motion planning can enable such an arm, a roughly $200 Waveshare RoArm-M2-S, under a fixed overhead camera to detect and color-sort writing utensils without that joint. A YOLO11n-OBB (You Only Look Once, oriented bounding box) detector locates each writing utensil; camera intrinsics and an ArUco reference pose convert its pixel coordinates to robot coordinates; and a color classifier labels it. The detected orientation angle determines the motion strategy: utensils close to the arm's fixed approach direction are picked up directly, and those at steeper angles are reoriented via corrective sweeps until they are graspable, after which they are picked up and sorted into the assigned color bin. Across 326 logged motions on seven writing utensils, the arm made 196 direct grasps and 130 corrective sweep passes, correcting misalignments up to 90 degrees, suggesting that clever task-informed engineering can compensate for a missing degree of freedom on tasks like this one.","url":"https://doi.org/10.48550/arxiv.2608.15968","authors":["Rangarajan, Anirudh","Bianchini, Bibit"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.15968","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.5281/zenodo.21986659","name":"Development of a Low-Cost Robotic Arm Controlled by ESP32 via Smartphone","source":"datacite","abstract":"This project consists of a low-cost, articulated robotic arm with four degrees of freedom—a mobile base, axis 1 (shoulder), axis 2 (elbow), and a gripper—developed by students from the Industrial Mechatronics Technology program at the SENAI Taubaté \"Félix Guisard\" School and College as a solution for the \"Saga SENAI\" challenge.

However, robust capture of objects with random shapes in dynamic working environments often comes at the cost of additional actuation channels and control complexity. Here, we introduce a tendon-driven, robust origami tentacle gripper by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. Each tentacle features carefully placed holes (for routing an actuation tendon), origami creases, and a tapered shape. By tailoring these design features, one can prescribe the shrinking, bending, and twisting deformation, eventually creating deterministic coiling with a simple tendon pull. Then, when multiple coiling tentacles are placed in proximity, stochastic entanglement emerges, allowing the tentacles to braid, knot, and grip objects with random shapes. We derived a simulation model by integrating origami mechanics with Cosserat rods to correlate origami design, tentacle deformation, and collective grasping performance. Then, we experimentally tested how these entangling origami tentacles can grasp objects under gravity and in water. A stow-and-release deployment mechanism was also tested to simulate in-orbit grasping.

Recent methods have demonstrated sample-efficient learning through human intervention but remain limited to small randomization ranges and encounter challenges with the non-stationarity induced by concurrently training multiple agents. To address these limitations, we introduce a unified framework that combines centralized training with decentralized execution (CTDE) and a Hybrid Reward Architecture (HRA). This enables multiple actors to share a centralized multi-head critic. The critic is decomposed into task and grasp heads, corresponding to the sparse task reward and a potential-based grasping reward, respectively. We accordingly reformulate the critic and actor objectives to exploit the decomposed Q-values while explicitly accounting for the categorical action distribution of the discrete gripper policy. Experimental results demonstrate that the proposed framework substantially improves both sample efficiency and policy performance. We validate our approach on two robotic arms and a simulated humanoid robot across tennis ball and banana pick-and-place, pot reset, and simulated block relocation tasks under dimension-wise domain randomization, approximately 5-25x larger than those considered in prior work. Compared with a state-of-the-art baseline, our method improves the success rate from 60% to 80% on tennis ball pick-and-place, from 60% to 90% on banana pick-and-place, and from 25% to 95% on simulated block relocation, while also successfully accomplishing a task where the baseline consistently fails.

GWM-VLA combines geometry-aware multi-view state encoding, global context-conditioned target-view prediction, and shared latent-action representations grounded by robot-action supervision.

Finally, the shared latent-action representations condition both the latent world model and the flow-matching action head, allowing latent-prediction supervision and ground-truth robot-action supervision to jointly shape the same latent-action representations.

Learning from demonstration offers a more direct alternative, but collecting demonstrations can still demand human teleoperation or kinesthetic teaching. This paper presents a self supervised visual manipulation method in which a robot automatically generates demonstrations around a target pose and learns relative pose corrections directly from wrist mounted RGB images. The proposed pipeline uses ROS~2 and Isaac Sim to collect labeled image-pose pairs without requiring explicit camera to robot extrinsic calibration. Separate datasets are generated for planar refinement and coarse three dimensional approach, and a convolutional network is trained to regress relative translation and rotation from single frame RGB observations. During execution, a coarse to fine controller first approaches the object using models trained with height variation and then refines the final alignment using planar data. The method is evaluated both in simulation and on a real UR5e collaborative robot equipped with a gripper and a monocular camera. In simulation, the refinement stage reduces the final planar dispersion from 9.69 mm to 5.38 mm. In real world experiments, the system performs end to end grasp attempts on three physical objects and reaches success rates of 66.6% and 63.6% for two objects without object rotation, while still maintaining partial robustness under rotated conditions.

While the human hand localizes these contacts effortlessly thanks to superior tactile sensitivity, robotic systems often lack the requisite resolution to acquire the information necessary for motion planning, resulting in clumsy manipulation or even task failure. Here, we propose transient extrinsic contact detection and ranging (TECDAR), a simple yet fast and efficient method for detecting and ranging extrinsic contact of grasped objects. Our design of gripper tips employs dynamic tactile sensing leveraging a single 2.5$\\times$3 mm 6D inertial measurement unit. The sensor captures sub-millisecond tip deformations at a 7 kHz sampling rate, but operating on a data stream of only 84 KB/s. High bandwidth and compact data size enable the system to rapidly detect and localize contact between grasped objects and their surroundings. Specifically, fusing tactile data with robot pose via an extended Kalman filter enables fast and precise localization of extrinsic contact, reaching millimeter-level accuracy within 180 ms. Experimental results demonstrate that the system achieves an average localization accuracy of approximately 7\\,mm in both line-contact and point-contact localization tasks. Furthermore, this near-instantaneous localization enables the robot to rectify its trajectory on a millisecond scale, facilitating precise tool manipulation and enhanced perception of complex environments purely through tactile exploration and mapping. We envision such techniques advancing the future of robotics across domains requiring delicate manipulation, including precision assembly, surgical assistance, and autonomous exploration in touch-dominant environments.

As engineering design continuously expands the boundaries of machine autonomy, mechanical systems are increasingly tasked with replicating subtle, delicate human actions. My interest in this sociotechnical dynamic stems directly from my hands-on experience building a four-degree-of-freedom handwriting robot. Crafting a machine capable of replicating handwriting, something seen as a very “human” thing, made me ask: As robots master tasks once considered uniquely human, where does this replication end, and are all human workers ultimately replaceable? This question shows why STS perspectives are important to engineering practice. Engineers must evaluate not only what a system can accomplish, but how its deployment alters human labor, organizational structures, and societal well-being. The technical portion of my capstone project focuses on designing, fabricating, and evaluating a four-degree-of-freedom (DOF) robotic arm engineered specifically for high-precision handwriting. The physical architecture features three “elbow” joints, a rotating base, and a dedicated gripper mechanism for pen orientation. To eliminate mechanical backlash—which introduces error during delicate, slow pen strokes—each rotational joint utilizes custom cycloidal speed reducers. Actuation is driven by servo motors integrated with absolute encoders, establishing closed-loop position control and real-time path execution via an onboard microcontroller running inverse kinematics algorithms. The outcome of this technical effort is a physical prototype capable of producing legible, repeatable handwritten text, demonstrating that low-backlash cycloidal gearing combined with closed-loop feedback allows relatively low-cost robotic systems to execute fine-motor tasks. In my STS research, I examine the sociotechnical impacts of manufacturing automation and robotics on the industrial workforce, focusing on labor polarization, deskilling, and psychological strain. Using a systematic literature and data review across labor economics and industrial psychology, the study analyzes the structural transition from manual execution to digital oversight. The results reveal that while automation increases production output, it hollows out mid-skill industrial roles, creating a \"barbell\" labor market split between low-wage service jobs and high-wage engineering positions. Furthermore, the findings demonstrate that transitioning workers from active physical creation to passive screen monitoring induces a decrease in job satisfaction. Ultimately, the research identifies that mitigating these negative impacts requires organizations to integrate proactive upskilling programs directly into the deployment phase of new technologies. Reflecting on these two projects through an STS lens shows the necessity of analyzing technical, organizational, and cultural elements simultaneously to uphold ethical engineering responsibility. STS frameworks force recognition of the broader sociotechnical problem: technology does not operate in a vacuum, but within complex human networks. By examining how fine-motor robotics threatens the current labor market, engineers can anticipate friction before implementation. Considering technical parameters alongside workforce culture and organizational incentives allows engineers to design systems that augment human capability rather than treat labor as an obsolete expense, ensuring that innovation ultimately aligns with ethical, human-centered values.","url":"https://doi.org/10.18130/pvbs-j671","authors":["Sommerville, Colin"],"tags":["Manufacturing","Automation","Workforce Displacement","Deskilling"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.18130/pvbs-j671","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:43.551Z"},{"id":"doi:10.5281/zenodo.21844970","name":"Field-Derived Effects of Fruit Rotation Angle on Detachment Force and Stem Retention for Robotic Kiwifruit Harvesting","source":"datacite","abstract":"This record contains the data and analysis materials supporting the study “Field-Derived Effects of Fruit Rotation Angle on Detachment Force and Stem Retention for Robotic Kiwifruit Harvesting.” The deposit includes fruit detachment-force and stem-retention measurements, fruit and stem physical-property data, friction measurements, excluded-observation records, a data dictionary, the gripping-force calculation workbook, and the statistical-analysis code.","url":"https://doi.org/10.5281/zenodo.21844970","authors":["Phan Le, Hung","McGuinness, Benjamin","Venter, Christoff","Prinz, Eva","Dhanotra, Karan","Hin Lim, Shen","Duke, Mike","Singh, Ajit Pal"],"tags":["Kiwifruit","Fruit Detachment Force","Fruit Rotation Angle","Stem Retention","Robotic Harvesting","Gripper Design"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.21844970","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.5281/zenodo.21844969","name":"Field-Derived Effects of Fruit Rotation Angle on Detachment Force and Stem Retention for Robotic Kiwifruit Harvesting","source":"datacite","abstract":"This record contains the data and analysis materials supporting the study “Field-Derived Effects of Fruit Rotation Angle on Detachment Force and Stem Retention for Robotic Kiwifruit Harvesting.” The deposit includes fruit detachment-force and stem-retention measurements, fruit and stem physical-property data, friction measurements, excluded-observation records, a data dictionary, the gripping-force calculation workbook, and the statistical-analysis code.","url":"https://doi.org/10.5281/zenodo.21844969","authors":["Phan Le, Hung","McGuinness, Benjamin","Venter, Christoff","Prinz, Eva","Dhanotra, Karan","Hin Lim, Shen","Duke, Mike","Singh, Ajit Pal"],"tags":["Kiwifruit","Fruit Detachment Force","Fruit Rotation Angle","Stem Retention","Robotic Harvesting","Gripper Design"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.21844969","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.5281/zenodo.21217588","name":"VISIONBOT VISualizIng and cONtrolling a roBOT via mixed reality interface","source":"datacite","abstract":"VISIONBOT is a Mixed Reality (MR) robotic teleoperation and monitoring system developed for the Meta Quest 3 headset and integrated with the Franka Emika Panda robot through ROS 2.

Other sectors such as the healthcare sector would also benefit from automated solutions for delicate handling of patients, including manipulation of soft tissues. Therefore, there is an urgent demand for soft robotic grippers, for the grasping and handling of soft and delicate objects. The key requirements for such handling are soft contact, ideally adaptable, and secure and safe holding to avoid potential damage during grasping and transportation. Liquid crystal elastomers (LCEs) are soft materials that combine the anisotropic properties of liquid crystal molecules known as mesogens with the elastic properties of a cross-linked polymer network. This unique structure enables them to undergo significant, reversible shape changes in response to external stimuli such as heat. They have shown great promise for soft robotics, as they are able to generate large reversible actuation, are soft and lightweight, can be programmed and have good payload-to-weight ratios. Current research has been focused upon understanding the working principles of LCEs and little work has been directed to their design and compatibility, particularly within soft robotic gripper applications. Many designs are either non-multi-material, resulting in direct contact of the hot LCE with the grasped objects, limited to bilayer designs or unable to handle large loads. 3D printing can enable more complex designs to be generated. In general, 3D printing of LCEs allows the precise control of the mesogen alignment, which determines how the material will deform upon application of a stimulus. 3D printing is desirable as complex LCE patterns can be manufactured, which would not be possible with traditional manufacturing methods. Multi-material printing of LCEs enables LCEs to be utilized for a wider variety of applications, as whilst LCEs have their advantages, they can struggle to provide support to generate large and applicable forces independently, and the introduction of other more rigid materials could help to avoid this drawback. Multi-material designs would enable LCEs to become not just an active material, but a key component in functional devices. However, there are very few available manufacturing systems, in particular those which can handle multi-material LCE printing, limiting the variety of LCE gripper designs. Additionally, very few systems can handle multiple pick and place methods for assembly, which is desirable, as currently integrated actuation and sensing within soft robotic grippers are rare. They often require multiple manual assembly steps, which can cause manufacturing errors. In general, soft robotic design and manufacturing are considered separately, resulting in inefficient development, and thus should be considered concurrently. Therefore, a multi-tool platform capable of multi-material, multi-method and multiple assembly methods, with the option for in situ monitoring is designed and manufactured within this investigation. This platform enables LCE based robotic grippers to be manufactured alongside smart soft robotic grippers. The capabilities of the platform are demonstrated by first manufacturing three different smart soft robotic gripper designs, each with different sensors, in a one-stop manufacturing process using the available tools. The sensors include commercially available sensors and a visual tactile sensor, which is also manufactured using the platform. The three designs proved to function when using it to grasp different objects. LCE is also manufactured using the platform. The quality of the LCE is investigated in detail to ensure the robustness of the platform for producing LCE based soft robotic gripp","url":"https://doi.org/10.17863/cam.132954","authors":["Yan, Hai Hui"],"tags":["Additive Manufacturing","Liquid Crystal Elastomers","Soft Robotic Grippers"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.17863/cam.132954","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.82419/379","name":"Grasping While Moving: A Compliant Hybrid Manipulation Framework for Robust Robotic Grasping","source":"datacite","abstract":"Robotic grasping in unstructured environments remains a fundamental chal lenge due to variability in object geometry, uncertainty in perception, and sen sitivity to end-effector alignment. Conventional grasping approaches typically rely on precise pose estimation, carefully planned contact configurations, and staged execution pipelines, which limits robustness when these assumptions are violated. This thesis investigates whether structured mechanical compliance, combined with continuous motion execution, can enable robust grasping under uncertainty without increasing system complexity. We propose a compliant hybrid manipulation framework that integrates a bio-inspired, tendon-driven soft gripper with a simplified rigid serial manip ulator. The gripper consists of eight spiral-shaped compliant arms arranged radially, enabling enclosure-based grasping through a single actuation input. This morphology allows passive adaptation to object geometry and reduces sen sitivity to angular misalignment and positional errors. The system is coupled with a lightweight perception pipeline based on RGB-D sensing, interactive segmentation, and geometric surface estimation to compute grasp reference points. A key contribution of this work is the formulation of a grasp-while-moving strategy, where grasp acquisition occurs during continuous motion rather than at a stationary grasp pose. This is achieved through velocity-controlled quintic trajectory generation with non-zero velocity at intermediate waypoints, com bined with synchronized gripper closure. Additionally, an angle-aware vertical offset compensation method is introduced to support stable surface-constrained manipulation tasks. The proposed framework is evaluated in both simulation and real-world experiments under controlled variations in object geometry, angular misalign ment, and translational pose uncertainty. Results demonstrate consistently high grasp success rates across diverse objects and orientations, with gradual performance degradation as uncertainty increases, in contrast to the abrupt failure observed in rigid grasping systems. These findings indicate that robustness can be achieved through the interaction between mechanical compliance and co ordinated motion, shifting complexity from perception and control to system morphology. Overall, this thesis shows that combining structured compliance with continuous execution provides a simple and effective approach for robust robotic grasping in uncertain environments.","url":"https://doi.org/10.82419/379","authors":["Kachwaa, Ramy Mohamed Yousef"],"tags":["Robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.82419/379","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.82308/26935","name":"Power-free shape retention in soft pneumatic actuators with multistability, multimodality and reprogrammability","source":"datacite","abstract":"Soft pneumatic robots have gained prominence due to their ability for safe and adaptive interaction with humans and delicate objects. This capacity stems from the high flexibility and stretchability of their constituent material, which can undergo large deformation with minimal force under pneumatic actuation. Despite their merits, soft pneumatic robots face two challenges for operation: (i) reliance on a continuous supply of pressure to attain deformation-driven functionality, and (ii) inability to alter their functional modes of deformation to access functionalities beyond those designed at the concept stage, i.e., pre-fabrication. In particular, on the first front, most soft pneumatic robots cease to retain their deformed shape upon pressure removal, hence depriving them of functionality, efficient use of energy resources, and immunity to puncture due to prolonged pressurization. On the second front, despite soft robotic arms being called to move along various trajectories to diversify end-effector locations, their deformation modes remain pre-determined by design and cannot provide additional motions that would enrich their as-designed kinematic space.This thesis introduces a design paradigm for soft pneumatic actuators that enables zero-power shape retention in extension, bending, and twisting, and a contact mechanism for reprograming multistable and multimodal responses post-fabrication. Chapter 2 presents the design concept for power-free shape retention, where the underpinning mechanism is the integration of a pneumatic transmitter and a multistable guider. Through theory, simulations, and experiments, the existence of four distinct regimes of deformation is unveiled, where the constituents first interact during inflation to attain locking in extension and bending, and then cooperate under vacuum to enable fully reversible functionality. The design paradigm is demonstrated to realize a soft robotic arm capable of locking at desired curvature states at zero power and a gripper that safely operates with puncture resistance to grasp and hold objects of various shapes, sizes, and consistencies. Chapter 3 introduces a reprogrammable metamaterial with twisting bistability, and incorporates modular stoppers into its architecture to initiate contact between the base frames that separate its snapping segment. The stopper heights can be tuned to initiate contact either before or during the snapping event. This enables the reprogramming of the metamaterial response to either twisting monostability or tune both the energy barrier and the twisting angle at the deployed stable state. In addition, the tailored distribution of stoppers initiates contact in preferential locations and demonstrates reprogrammability of functional deformation. The metamaterial is then integrated with a pneumatic transmitter for experimental investigation of its twisting actuation. The actuator architecture is finally leveraged to design a soft pneumatic arm whose deformation modes can be reprogrammed in-situ to attain multiple trajectories beyond those sealed by design, and all retained without continuous pressure supply.Overall, this research makes contributions in two key areas. First, it achieves power-free operation of soft pneumatic actuators in three basic deformation modes, offering energy-efficient solutions for fields such as medical devices and wearable assistive devices. Second, it introduces the ability to reprogram contact for tuning multistable and multimodal responses, enhancing the versatility and functionalities of current soft robots and inspiring the design of novel soft metamaterials","url":"https://doi.org/10.82308/26935","authors":["Rahman, Shakurur"],"tags":["Mechanical Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.82308/26935","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.82308/44543","name":"Hydrogel artificial ionic skins for wearable electronics and soft robotics","source":"datacite","abstract":"L'hydrogel en tant que matériau mou biomimique a été étudié de manière intensive pour des dispositifs ioniques ou iontroniques.

L'AIskin se compose d'une bicouche d'hydrogel à double réseau de charge opposée qui convertit les stimulis mécaniques et l'humidité en signaux de résistance, de capacité, de tension en circuit ouvert (OCV) et de courant de court-circuit (SCC), parmi lesquels les signaux de l'OCV et SCC sont auto-générés.

The innovative design of pitch-roll wrists using spherical cam-roller pairs is currently underway at McGill University's Centre for Intelligent Machines, with the aim of overcoming the drawbacks of bevel-gear trains. This innovative design relies on Speed-o-Cam, a new concept of speed-reduction mechanisms based on cams and pure-rolling contact, intended to replace gears and harmonic drives in applications where backlash, friction, and flexibility cannot be tolerated. The new mechanism consists mainly of a spherical conjugate cam subassembly and two roller-carrying disks. We start with a study of cam curvature, with special focus on its machinability. Drawing from experience, we introduce the hypothesis that high curvature changes of a cam profile are at the source of the concentration of machining errors. As a consequence, the machining accuracy of the concave regions in a cam profile is substantially lower than that of its convex regions. To produce a more accurate cam we developed the geometric condition that guarantees a fully convex spherical cam profile. The optimum design of the pitch-roll mechanism based on cam-roller pairs is reported here. The optimization is intended to simplify the subassembly of spherical conjugate cams of the old design by means of a layout of two pairs of spherical mechanisms of the Stephenson type and two conjugate cams mounted on distinct shafts. We focus on the optimum design of both the spherical cam-roller mechanism and the spherical Stephenson mechanism.","url":"https://doi.org/10.82308/20424","authors":["Hernandez, Sergio"],"tags":["Mechanical Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2004","doi":"10.82308/20424","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.82308/30234","name":"Sensor-based autonomous control of dynamic robotic manipulation","source":"datacite","abstract":"Autonomous grasping in dynamic environments where the object, the robot or both are moving is an increasingly common task in robotic applications. This thesis describes an online trajectory planner--a geometric controller--which evaluates a nonlinear memoryless function to map the current object position and velocity into a desired robot pose. If the robot tracks these set points, it is guaranteed to match the object's velocity and acceleration on a specified grasp surface. A planar simulation demonstrates that this paradigm performs favorably when compared with the traditional planning approach. Since it does not depend on future state predictions, no object model is required. Without trajectory prediction, the computational effort is drastically reduced, allowing for higher controller speed and tracking feedback gains. The geometric controller has been successfully implemented on the 7 dof Sarcos Dextrous Arm. In order to provide the critical local sensing just before robot-environment contract, this thesis reports on work in progress toward the development of a proximity sensing network, located in a robot's multi-fingered gripper.

Three components target different axes of the problem: dual-view temporal input of 16 history frames per step with textual camera and time markers; hierarchical chain-of-thought (CoT) distillation from a 35B teacher into an episode-level Plan and a chunk-level Think span over task phase, gripper state and next subaction; and paraphrase augmentation expanding 40 base commands into 800 variants. On LIBERO-Plus, spanning 10,030 perturbed tasks across seven perturbation dimensions, CoTinyVLA reaches 90.8% on Spatial, 87.3% on Object, 86.6% on Goal and 80.7% on Long, leading the strongest 7B baseline on all four suites by 4.7, 2.8, 15.9 and 3.0 points, with every margin interval excluding zero. The gains concentrate on the hardest axes of the benchmark: across the eleven published baselines none exceeds 53.2% on Robot Initial States in any suite, whereas CoTinyVLA reaches 73.6% on Goal against 39.9% for the strongest baseline. Ablations show the three components to be separable by perturbation axis, and at a matched image budget how frames are divided between the two cameras and across time accounts for 8.6 points on its own. Closed-loop inference peaks at 2.25 GiB of allocated GPU memory, and paired interventions show the episode Plan to be load-bearing: replacing it with an empty or contradictory span costs 40 to 45 points of success. Structured supervision thus lets a 0.9B backbone exceed all of them.

A single RGB-D camera captures the operator's arm motion and hand gestures without wearables, fiducials, or a calibration stage. The intended target is specified by a free-form text prompt, grounded by a vision-language model in the robot's gripper camera, and tracked across its onboard cameras by a promptable video-segmentation model, resulting in a grasp frame continuously separated from the obstacle map. Every commanded motion is executed by a GPU-accelerated model-predictive controller that enforces self- and environment-collision avoidance against an online volumetric reconstruction, while a potential field corrects the operator's reference toward the grounded target during the final approach. An autonomous mode can be gesture-triggered to complete the grasp on the same target without a separate perception pipeline. The framework is validated on a quadruped mobile manipulator. The interface achieves a positional RMSE of 59 mm relative to motion-capture ground truth, and the controller keeps the arm at least 18 cm from obstacles while the operator deliberately commands the arm into them by 6 cm.

However, existing systems often suffer from limited procedural coverage because constrained patient-side setups, restricted flexibility, and complex instrument exchange hinder clinical workflow integration. This work presents a compact robotic system for endovascular interventions that enables continuous translational and rotational manipulation of standard endovascular instruments. The system consists of two alternating carts with pneumatically actuated membrane grippers integrated into rotating gripper gears. Its top-loading design allows rapid exchange of instruments such as guidewires and catheters without changing the robotic setup. A leader-follower control strategy enables continuous motion despite the finite stroke of each cart. The system was evaluated in motion-tracking experiments with guidewires and catheters and in an in vitro vascular phantom. The motion-tracking experiments showed generally smooth translational and rotational motion profiles. Across all tested guidewire and catheter experiments, the mean relative tracking errors were 3.6% for translational motion and 4.1% for rotational motion. In the vascular phantom, robot-assisted navigation reached the target in most trials, demonstrating the feasibility of the proposed manipulation concept under in vitro conditions. The presented robotic system demonstrates technical feasibility for continuous manipulation of standard endovascular instruments in bench-top and in vitro experiments. The compact top-loading design may ease instrument exchange and clinical workflow integration. Future work will focus on improving gripping performance, actuation speed, force feedback, and evaluation in more clinically realistic settings.","url":"https://doi.org/10.48550/arxiv.2607.11779","authors":["Fischer, Jonas","Karstensen, Lennart","Mathis-Ullrich, Franziska"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2607.11779","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.48550/arxiv.2607.09515","name":"One-Shot Multimodal Learning from Demonstration with Force-Constrained Elastic Maps","source":"datacite","abstract":"Robotic manipulation tasks often require simultaneous reasoning over motion and contact forces, yet most Learning from Demonstration (LfD) methods model only spatial trajectories and neglect force interactions with the environment.

One approach for achieving this involves measuring the coefficient of static friction (COE) at the gripper-object interface. In the absence of torque, the minimum grip force to prevent slip can be estimated from COE and the contact forces . However, torque at the gripper-object interface is generated when the lifting force does not align with the weight vector of the object being lifted. Current robotic gripping systems ignore the need to measure COE, and there is little literature on the grip force required to prevent slip in the presence of a tangential torque (T) at the gripping interface. In this thesis, a grip force control system was developed, using the measurement of COE at the first contact between the gripper and the object, and the continuous measurement of contact forces and torque to approach the minimal grip force required to hold the object stably. The target grip force is determined in real-time during object manipulation. To demonstrate the importance of COE when no torque is present, objects were gripped with the target grip force dependent only on the measured loads and COE. Furthermore, a model was developed in which the minimum grip force preventing slip can be estimated based on COE, load force, and T. This friction model is first validated with respect to the grip force at which slip is predicted to occur, for varying COE, load force, and T. Objects were then gripped (varying load, COE, and T) with the target grip force calculated by the friction model. The results demonstrate that COE-dependent grip force control is superior to gripping without knowledge of COE, irrespective of T at the contact interface, with respect to the system’s ability to prevent slip and simultaneously minimise the grip force applied. The minimum grip force estimation model and grip force controller developed and validated in this thesis have highlighted the value of measuring COE and the necessity of countering torque to ensure a secure and efficient grip.","url":"https://doi.org/10.26190/unsworks/3725","authors":["Wen, Han"],"tags":["Force control system","Coefficient of static friction","Tangential torque","Robotic gripping","Preventing slip"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.26190/unsworks/3725","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.26190/unsworks/25146","name":"Bio-Inspired Soft Artificial Muscles for Robotic and Healthcare Applications","source":"datacite","abstract":"Soft robotics and soft artificial muscles have emerged as prolific research areas and have gained substantial traction over the last two decades. There is a large paradigm shift of research interests in soft artificial muscles for robotic and medical applications due to their soft, flexible and compliant characteristics compared to rigid actuators. Soft artificial muscles provide safe human-machine interaction, thus promoting their implementation in medical fields such as wearable assistive devices, haptic devices, soft surgical instruments and cardiac compression devices. Depending on the structure and material composition, soft artificial muscles can be controlled with various excitation sources, including electricity, magnetic fields, temperature and pressure. Pressure-driven artificial muscles are among the most popular soft actuators due to their fast response, high exertion force and energy efficiency. Although significant progress has been made, challenges remain for a new type of artificial muscle that is easy to manufacture, flexible, multifunctional and has a high length-to-diameter ratio. Inspired by human muscles, this thesis proposes a soft, scalable, flexible, multifunctional, responsive, and high aspect ratio hydraulic filament artificial muscle (HFAM) for robotic and medical applications. The HFAM consists of a silicone tube inserted inside a coil spring, which expands longitudinally when receiving positive hydraulic pressure. This simple fabrication method enables low-cost and mass production of a wide range of product sizes and materials. This thesis investigates the characteristics of the proposed HFAM and two implementations, as a wearable soft robotic glove to aid in grasping objects, and as a smart surgical suture for perforation closure. Multiple HFAMs are also combined by twisting and braiding techniques to enhance their performance. In addition, smart textiles are created from HFAMs using traditional knitting and weaving techniques for shape-programmable structures, shape-morphing soft robots and smart compression devices for massage therapy. Finally, a proof-of-concept robotic cardiac compression device is developed by arranging HFAMs in a special configuration to assist in heart failure treatment. Overall this fundamental work contributes to the development of soft artificial muscle technologies and paves the way for future comprehensive studies to develop HFAMs for specific medical and robotic requirements.","url":"https://doi.org/10.26190/unsworks/25146","authors":["Phan, Phuoc Thien"],"tags":["soft robotics","soft artificial muscles","wearable robotic glove","smart surgical sutures","tubular gripper","smart textiles","compression garments","heart assist device"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.26190/unsworks/25146","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:15.835Z"},{"id":"doi:10.26190/unsworks/25191","name":"Shape Programmable and Multifunctional Soft Textile Muscles for Robotics and Wearable Applications","source":"datacite","abstract":"Soft robotics is a rapidly advancing research area where robots are made of soft materials. Generally, soft robots rely on soft artificial muscles for their actuation. Among all types of soft artificial muscles, planar fluidic textile muscles can have a low profile, high flexibility, and facile incorporation with additional components (e.g., soft sensors, variable stiffness structures (VSSs), and stretchable conductors for electrical wiring) to create multifunctional active textile structures for robotic and wearable applications. Despite advances, the capabilities of current fluidic planar textile muscles have not been fully explored, and therefore, further efforts including new designs and fabrication methods are necessary to facilitate the development of such structures. This thesis aim to investigate the development of multifunctional, planar soft textile muscles, with the focus on different design and fabrication methods to achieve various textile soft grippers, a low-modulus stretchable conductive material, and a new class of programmable, planar textile muscles. The thesis starts with the development of a multi-fingered fabric gripper based on fluidic, planar textile bending actuators that could incorporate a VSS with a gecko-inspired adhesive layer for enhanced gripping performance. It will then introduce an innovative bio-inspired continuum helical gripper incorporating a core fluidic textile muscle for helical winding motion, a VSS for high-loading gripping, and a novel soft tactile sensor for touch sensing. As low-modulus stretchable conductors are highly useful in soft robotic structures, this thesis also introduces a novel fabrication strategy to create a low-modulus stretchable conductive composite which can be fabricated into stretchable conductors of diverse configurations. Finally, this thesis presents a new class of fluidic, planar textile muscles with a new fabrication method that has a high potential for combination with automated manufacturing processes.

Conventional strain sensors, such as strain gauges, are typically designed to respond to strain in a single direction and are attached on the external surface of a structure. In this PhD research project, direction-selective sensors have been developed based on constriction-resistive and microcracking mechanisms and 3D printing methods have been employed for integrating the sensors directly into/on soft robots. Using a carbon nanotube reinforced polylactic acid (PLA-CNT), both sensing elements and conductive interconnects are 3D printed. For the constriction-resistive sensors, the sensitivity and anisotropy can be adjusted by controlling the air gap between printed adjacent tracks, infill density, and build orientation relative to the main loading direction. In particular, sensors printed with a near-zero air gap, i.e., adjacent tracks form a kissing bond, can achieve a gauge factor of ~2300 perpendicular to the raster orientation and a gauge factor of ~1 parallel to the raster orientation. The maximum directional selectivity of this ultra-sensitive sensor is 50.5, which is unprecedented among multidirectional sensors so far. The high sensitivity stems from the progressive opening and closing of the kissing-bond between adjacent tracks. This sensor proved to be able to sense the tiny strain resulted from the propagation of the ultrasonic wave in a solid plate as well. The constriction-resistive strain sensors only can operate in a small strain range. To detect strains in large strain ranges (&gt;50%), a simple, low-cost, and scalable method of printing PEDOT:PSS thin film strain sensor onto 3D printed TPU is introduced to create highly stretchable integrated piezoresistive strain sensors and stretchable conductors for soft actuators. High strain sensitivity of ~ 417 is achieved with a linear working strain range of up to 100% strain. The high sensitivity stems from the non-continuous fragmentation of the PEDOT:PSS sensing layer on the patterned 3D printed TPU substrate. Furthermore, by changing the printing orientation of the TPU substrate from 0 to 90 degrees, the PEDOT:PSS layer turned insensitive to strain i.e. became a good conductor. The perpendicular-oriented transducer is used as a conductor while the parallel-oriented transducer is a sensor. To demonstrate the impact of this technology, we fabricate a surgical soft tentacle gripper (SSTG) that is controlled using a sensorized glove. We demonstrate precision control of the catheter bending motion with high accuracy of 99%, which shows the potential of using our sensor technology in minimally invasive soft robotic surgeries.","url":"https://doi.org/10.26190/unsworks/4003","authors":["Mousavi Anchehpoli, Seyed Saeb"],"tags":["constriction-resisitive sensor","multidirectional strain sensor","3D printing","variable thickness sensor","soft robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.26190/unsworks/4003","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.5281/zenodo.21276786","name":"Reinforcement Learning for Robotic Gripping using Unreal Engine","source":"datacite","abstract":"Vision-based reinforcement learning allows robots to develop control policies directlyfrom visual stimuli; nevertheless, learning manipulation from images is difficult due topartial observability and unpredictable contact dynamics.

Automation is key to overcoming these barriers, yet flexibility is crucial due to the field’s frequently changing processes.. This thesis presents methods to promote flexible, modular automation in tissue engineering. It addresses both intra-process automation within individual modules and inter-process automation connecting them. Focusing on biomaterial shaping as one of the many tasks in tissue engineering, the thesis first introduces a camera-based monitoring system for inverse gelation, a process used to manufacture core-shell capsules. Combined with a convolutional neural network to segment and characterize the properties of core-shell capsules, it improves parameter-tuning efficiency and reproducibility. For extrusion-based bioprinting, where automation is already more advanced, a novel bioextrusion printhead was developed. It enables flow-rate-controlled extrusion without requiring a sensor in direct contact with the biomaterial, thereby maintaining a constant flow even under variable conditions. This innovation improves the reproducibility and quality of printed structures while preserving material integrity. Finally, a sterile robotic workbench and a compliant mechanism gripper for handling delicate tissues in microplates have been developed. Their cleanability and low particle emission rate support sterile operation. They enable full automation by providing safe, reliable transport between automated modules, which can be easily integrated into the setup. This promotes increased throughput while also ensuring high quality and robust documentation.

They enable robots to interact with objects in their work area. Grippers have a wide range of differentiation focused on the operation performed and the properties (e.g. shape) of the object being gripped. Their design and functionality are constantly being modified, tuned and developed by both academic and industrial units. Consequently, this paper presents a proposal for a lightweight jaw using MR fluid, which can be implemented in a jaw gripper (e.g. Robotiq 2F-140) to form a hybrid soft-rigid structure. In addition, methods are presented for studying the use of soft structures in a jaw gripper. As part of the work carried out, a model of the cushion and jaw of the gripper was developed, the FEM was used to obtain the character of the deformation when the object is axially plunged into it. Experimental plunging tests as well as dynamic tests of object transfer were also carried out. The work carried out allowed to demonstrate several key aspects of the grippers area. The soft structures of the grippers should be studied in terms of the force required to deform them. This determines their applicability to fragile and deformable objects. Dynamic measurements of the handling of objects of different shapes, with simultaneous measurement of force, allow the effectiveness of the use of soft structures in the gripper to be determined. Such experiments will make it possible to determine the measurable stability and repeatability of the grasp. The results of the research and experiments will be particularly applicable to robotic arms with relatively low lifting capacity.","url":"https://doi.org/10.21203/rs.3.rs-5038596/v1","authors":["Marcin Białek","Dominik Rybarczyk"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-5038596/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.21203/rs.3.rs-5332238/v1","name":"Voice Controlled 6 DoF Arm Mobile Robot in an Assisted Home Environment","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-5332238/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-5332238/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.20944/preprints202409.1948.v1","name":"CAD Design and Modeling of a Robotic Arm for Automated Harvesting","source":"europepmc","abstract":"The increasing demand for agricultural automation within the precision agriculture sector necessitates the development of advanced robotic systems to enhance efficiency in fruit harvesting.

This potential is largely attributed to the inherent flexibility and compliance of soft robots. A critical aspect in the development of these robots lies in the selection and utilization of appropriate soft actuators and materials. Nevertheless, the modeling of soft robots presents considerable challenges owing to their intricate properties and continuum nature. In this article, we focus on the design and modeling of a three dimensional (3D) printed soft bellows actuator. The primary objective is to assess its efficacy in creating suitable soft grippers for handling various practical products. We propose an empirical model to predict the output forces of the soft bellows actuator. This model comprehensively integrates parameters such as bellows geometry and material properties, thereby providing valuable insights for the actuator’s design and control. To ascertain the precision of our model, we conducted a series of finite element (FE) simulations considering different designed parameters of the bellows, and performed experimental validations using 3D printed bellows actuators. The empirical model demonstrated high accuracy in predicting the output forces of the bellows actuator, with average absolute and relative errors of 1.35 N and 10%, respectively. As an application, a robotic gripper with two parallel bellows actuators was developed, and its grasping force was validated using the empirical model. Building on this, a robotic gripper incorporating three bellows actuators was designed and fabricated based on the empirical model, and high-speed pick-and-place experiments were effectively conducted for handling a range of products.","url":"https://doi.org/10.21203/rs.3.rs-4632873/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4632873/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-3134997/v1","name":"A Novel Rigid-Soft Gripper for Safe and Reliable Object Handling","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3134997/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3134997/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.20944/preprints202311.1696.v1","name":"Design, Fabrication, and Characterization of a Novel Optical 6-Axis Distributed Force and Displacement Tactile Sensor for Dexterous Robotic Manipulation","source":"europepmc","abstract":"","url":"https://doi.org/10.20944/preprints202311.1696.v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.20944/preprints202311.1696.v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21203/rs.3.rs-4451674/v1","name":"Multi-Stable Origami Structures with Thick Panels","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4451674/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4451674/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.21203/rs.3.rs-3227382/v1","name":"Experimental assessment and prediction of design parameter influences on vacuum-based granular grippers","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3227382/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3227382/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.20944/preprints202404.0298.v1","name":"Nighttime Harvesting of OrBot (Orchard roBot)","source":"preprints","abstract":"","url":"https://doi.org/10.20944/preprints202404.0298.v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.20944/preprints202404.0298.v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.21203/rs.3.rs-3665801/v1","name":"Skin-inspired, sensory robots for electronic implants","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3665801/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3665801/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.21203/rs.3.rs-2222352/v1","name":"Vision-based In-Hand Manipulation via Picking up by a Two-fingered Robotic Hand with Conveyor Belts","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-2222352/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-2222352/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.21203/rs.3.rs-1271178/v1","name":"Robotic Grasp/Motion Planning for Efficient Packing Assuming Multiple Grippers","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-1271178/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-1271178/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.21203/rs.3.rs-10032842/v1","name":"Large language models do not replace chemists in a closed-loop catalysis experiment","source":"preprints","abstract":"Abstract Artificial intelligence (AI) is reshaping scientific research and laboratory automation1. Large language models (LLMs) can perform aspects of scientific reasoning, which could in principle reduce human decision-making as a rate-limiting step in closed-loop automated experiments2-7. Yet the reasoning performance of LLMs compared with human experts in complex, noisy, long-running laboratory experiments is largely unexplored. Here we benchmarked LLM reasoning head-to-head against a team of human domain experts for a noisy 25-dimensional closed-loop colloidal catalysis problem8 explored using a mobile robot9. The LLM (GPT-5.1) navigated the available chemical space across a 528-experiment campaign, using background information and experimental data to propose an anionic surfactant that gave the largest single gain in catalyst activity, also adapting to a mid-campaign change in the measurement set-up. In a like-for-like final phase of 160 experiments, the human experts found a catalyst formulation that was, on average, more active than the best two formulations found in independent LLM runs. At the same time, the LLM reasoned 35 times faster and was estimated to be around 1,900 times less expensive than human reasoning. Inspection of the LLM reasoning traces found them mostly sound, but with some costly silent errors, logical inconsistencies, and apparent memory limitations, suggesting that LLMs are not out-of-the-box replacements for expert reasoning in problems of this complexity10. This points to a need to design closed-loop systems that combine the speed of machine reasoning with expert oversight.","url":"https://doi.org/10.21203/rs.3.rs-10032842/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-10032842/v1","addedAt":"2026-08-31T06:34:15.835Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.21203/rs.3.rs-1654721/v1","name":"Flexible

design and performance evaluation of a soft crawling robot driven by a rolled dielectric elastomer actuator","source":"crossref","abstract":"Abstract Dielectric elastomer actuators (DEA) are lightweight and compliant actuators for soft crawling robots, but converting actuator deformation into stable directional locomotion remains challenging because of structural compliance, passive foot-ground interaction and material hysteresis. In this work, a soft crawling robot driven by a rolled DEA (RDEA) is designed, fabricated and experimentally evaluated. The robot consists of a spring-supported rolled actuator and two passive asymmetric-friction feet, which convert voltage-induced axial deformation into forward crawling motion. An equivalent finite element model of the active rolled actuator was developed in ABAQUS to analyse the voltage-dependent axial deformation under equibiaxial pre-stretching, spring pre-compression and Maxwell-pressure loading. Under a 300% × 300% pre-stretch and a driving voltage of 7 kV, the model predicted an electrostatic deformation ratio of 16.9%, providing the kinematic input for estimating the ideal crawling velocity. A square-wave voltage driving system was then used to evaluate the crawling behaviour of the fabricated prototype under fixed test-surface conditions. The robot reached a maximum measured crawling speed of 4 mm s −1 at 7 kV and 2 Hz, corresponding to approximately 0.04 body lengths per second. The measured velocity was lower than the ideal estimate, mainly because of foot slip, frictional dissipation, structural compliance, dielectric loss and elastomer viscoelasticity. These results indicate that a RDEA combined with passive asymmetric-friction feet provides a simple actuation scheme for compact soft crawling mechanisms, while improvements in foot design, electrical efficiency and long-term motion stability remain necessary.","url":"https://doi.org/10.1088/2631-8695/ae924e","authors":["Sijiao Wang","Yanlin Chen","Yuxin Jiang","Le Yang","Hongxi Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-29T22:54:47Z","doi":"10.1088/2631-8695/ae924e","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.3390/books978-3-7258-7822-2","name":"Actuator Technologies and Control","source":"crossref","abstract":"","url":"https://doi.org/10.3390/books978-3-7258-7822-2","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-01T05:35:00Z","doi":"10.3390/books978-3-7258-7822-2","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1016/j.ijmecsci.2026.111805","name":"Bistable actuator tuned via flexible hinges for bioinspired jellyfish robot","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.ijmecsci.2026.111805","authors":["Xiuhui Hou","Songxuan Li","Feng Xie","Zichen Deng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-06T03:50:11Z","doi":"10.1016/j.ijmecsci.2026.111805","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1016/j.sna.2026.118299","name":"Design of hybrid robot arm with 4-bar linkage joint using soft electrohydraulic actuator","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.sna.2026.118299","authors":["Jeonghun Lee","Youngsu Cha"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-27T23:23:06Z","doi":"10.1016/j.sna.2026.118299","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1109/aim65483.2026.11658238","name":"Proposal of an Earthworm-Type Robot with Front and Rear Hyper-extension Soft Actuator Units and Verification of Its Crawling Performance in Elbows","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim65483.2026.11658238","authors":["Yuiga Kanno","Fumio Ito","Taro Nakamura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-25T19:16:23Z","doi":"10.1109/aim65483.2026.11658238","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1109/ecitech69277.2026.11601375","name":"Visual Positioning Method for End-of-Line Actuator of High-Voltage Transmission Line Pin Replacement Robot","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ecitech69277.2026.11601375","authors":["Fei Sheng","Yingxu He","Kun Wang","Zhipeng Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-20T20:18:07Z","doi":"10.1109/ecitech69277.2026.11601375","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1002/aisy.202501252","name":"Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot","source":"crossref","abstract":"Under‐actuated compliant systems have emerged as a promising solution to the challenges of actuation and control in soft robotics.

This configuration enables four distinct locomotion modes: forward motion, turning, and lateral translations. The design simplifies fabrication and aligns with the Soft Curved Reconfigurable Anisotropic Mechanism paradigm. A modified pseudo‐rigid body model is developed and integrated into the MuJoCo simulation environment to accurately capture the robot's dynamics. Experimental validation and sensitivity analysis are conducted to evaluate performance under varying conditions, and reinforcement learning is employed to optimize locomotion strategies.

Legacy hydraulic circuits increasingly suffer from severe leaks that force well shutdowns, compromise barrier integrity and require interventions that involve complete christmas tree retrieval using drilling rigs. The retrofit electrical actuator replaces failed hydraulic actuation with a fully electric system that mounts directly onto the existing ROV manual valve override interface. Powered by subsea battery modules and integrated into the tree existing power and communication network, the system restores full remote operability including autonomous fail-safe closure, while remaining completely transparent to topside controls. Installation is rapid - typically one day using a Field Service Vessel - dramatically reducing production downtime and operational expenditure. The architecture combines a robust actuator with a fault-tolerant Actuator Control Module featuring redundant sensing, advanced motion control and a long-life battery pack qualified for subsea deployment up to 3000 meters water depth. Comprehensive technology qualification activities have verified system performance across mechanical, electronic, environmental and system integration domains, enabling the technology to reach TRL 6. By enabling fast, nonintrusive restoration of christmas tree valve function while maintaining full barrier compliance, the actuator system introduces a new, scalable approach to subsea asset life extension.","url":"https://doi.org/10.4043/37215-ms","authors":["S.

Twisted and coiled polymer actuators (TCPAs) made from nylon fishing lines show promise owing to their low cost, ease of fabrication, and high deformation capabilities. However, conventional heating methods using copper or nichrome wires are frequently limited by low thermal response rates and durability issues. In this study, we introduce a new heating technique in which five conductive fibers are twisted together and uniformly wrapped around the TCPA to improve heat transfer efficiency and allow operation at higher input voltages. In addition, we propose a unit design that bundles multiple TCPAs into a helical fiber structure (CF‐HFS TCPA) for increased force generation. Experimental results show that the performance of single TCPA_CF units is strongly dependent on wire gauge: under light loads of approximately 1.96–2.45 N, finer wires achieve higher displacement ratios at high voltages, whereas under loads of approximately 2.94 N, their performance declines, while thicker wires maintain stable operation over a wider load range. Temperature measurements show that, while gauges achieve high surface temperatures under light loads, the temperature rise is reduced under heavy loads owing to reduced contraction and increased heat dissipation. Overall, these findings support the potential utility of our approach as an effective method for developing actuators for soft robotic and wearable applications.","url":"https://doi.org/10.20965/jrm.2026.p0329","authors":["Masataka Nakabayashi","Yuhi Tamura","Ayana Mikuni"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-02-19T15:02:07Z","doi":"10.20965/jrm.2026.p0329","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.1109/isivc69944.2026.11574371","name":"Adaptive Terminal Sliding Mode Control for Secure Cyber-Physical Systems: The case of a robot manipulator under actuator/sensor cyber-attacks","source":"crossref","abstract":"","url":"https://doi.org/10.1109/isivc69944.2026.11574371","authors":["Brahim Moudoud","Rachid Fateh","Abdelhafid El Farnane","Kaoutar Ahed","Elhoucine Ouassam","Hicham Aissaoui"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-01T19:34:17Z","doi":"10.1109/isivc69944.2026.11574371","addedAt":"2026-08-31T06:34:16.225Z","updatedAt":"2026-08-31T06:34:16.225Z"},{"id":"doi:10.2514/6.2026-0893","name":"Coupling of Actuator Line Method with Vortex Lattice Method in a Vortex-based Actuator Lattice Method","source":"crossref","abstract":"","url":"https://doi.org/10.2514/6.2026-0893","authors":["Paulo C.

Several methods have been proposed, such as PID and MRAC; however, their accuracy still needs improvement. Meanwhile, FT-SMC offers high accuracy, but its methodological complexity results in longer execution time and reduced computational efficiency. The objective of this research is to develop a fault-tolerant control method that can maintain system performance under actuator degradation while achieving high tracking accuracy with improved computational efficiency. Simulations are performed with a two-link manipulator model with sinusoidal reference trajectories. An actuator fault is introduced at 4 s by reducing the actuator effectiveness to [0.5, 0.7]ᵀ, meaning that the actuator capability decreases to 50% and 70% of its nominal performance, respectively. The simulation results show that the proposed FTC controller maintains good tracking performance after the fault occurs. In contrast, the controller without FTC experiences performance degradation characterized by phase lag and amplitude attenuation in the system response. Furthermore, the actuator effectiveness estimation mechanism demonstrates fast convergence after the fault occurs, with settling times of approximately 0.084 s and 0.238 s for the first and second joints, respectively. The steady-state MAEs are 0.0080 and 0.0395, equivalent to relative errors of 1.6% and 5.6%, respectively. Compared with other FTC methods, the proposed FTC controller also provides a balanced trade-off between tracking accuracy, robustness under fault conditions, and computational efficiency, making it suitable for real-time implementation.","url":"https://doi.org/10.59247/jfsc.v4i1.397","authors":["Anisa Ulya Darajat","Swadexi Istiqphara","Heriansyah","Mohammad Farhan Ferdous","Abu Saleh Musa Miah","Uri Arta Ramadhani","Hari Maghfiroh"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-26T14:52:42Z","doi":"10.59247/jfsc.v4i1.397","addedAt":"2026-08-31T06:34:16.226Z","updatedAt":"2026-08-31T06:34:16.226Z"},{"id":"doi:10.1109/mra.2025.3533386","name":"Reconfigurable Modular Soft Actuator Using Origami Structures With Self-Healing Materials: Several Technological Opportunities for Robotic Applications","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mra.2025.3533386","authors":["Lisbeth Mena","Seppe Terryn","Bram Vanderborght","Concepción A.

This decoupled design space enables the selection of numerous useful properties (e.g., abrasion resistance, high specific work, etc.). Using this, we demonstrate that the HARP can satisfy the requirements of diverse applications by tuning the selection of parameters.

This study proposes a novel bio-inspired electro-hydraulic humanoid robot that incorporates a parametric dynamic model based on the coupled muscle-tendon-bone characteristics of the human hip-knee-ankle complex. Leveraging a custom-designed, reverse-inverse kinematics framework, the leg morphology and electro-hydraulic actuator parameters are co-optimized to enhance agility and obstacle-crossing capabilities. To simultaneously ensure structural strength and mass control, honeycomb structures are designed for the leg components, achieving functional lightweighting while preserving balanced strength across different directions. Simulation analyses demonstrate that a 21.28% weight reduction is attainable while maintaining comparable out-of-plane equivalent elastic and shear moduli relative to the original structure, thus meeting the demands of complex loading and impact conditions. Experimental tests confirm that the robot exhibits robust environmental adaptability and stable locomotion during high-speed running at 10 km/h and obstacle traversal over 300 mm.

The performance of the PTC is rigorously evaluated against SMC on two representative planar trajectories. Obtained results demonstrate that the proposed method achieves faster and precisely adjustable convergence, particularly with smaller, mission-critical time horizons. While SMC offers robust stability for applications where smooth operation is paramount, the predefined-time approach is particularly well suited for time-sensitive missions.

This work introduces Certified Gaussian Manifold Sampling (C-GMS), a novel trajectory-centric RL framework that learns combined DMP and VIC policies while guaranteeing Lyapunov stability and actuator feasibility by construction. Our approach reframes policy exploration as sampling from a mathematically defined manifold of stable gain schedules. This ensures every policy rollout is guaranteed to be stable and physically realizable, thereby eliminating the need for reward penalties or post-hoc validation. Furthermore, we provide a theoretical guarantee that our approach ensures bounded tracking error even in the presence of bounded model errors and deployment-time uncertainties.

Inspired by these biological features, we present PuffyBot, an untethered shape morphing robot capable of changing its body morphology to navigate multiple environments. Our robot design leverages a scissor-lift mechanism driven by a linear actuator as its primary structure to achieve shape morphing. The transformation enables a volume change from 255.00 cm3 to 423.75 cm3, modulating the buoyant force to counteract a downward force of 3.237 N due to 330 g mass of the robot. A bell-crank linkage is integrated with the scissor-lift mechanism, which adjusts the servo-actuated limbs by 90 degrees, allowing a seamless transition between crawling and swimming modes. The robot is fully waterproof, using thermoplastic polyurethane (TPU) fabric to ensure functionality in aquatic environments. The robot can operate untethered for two hours with an onboard battery of 1000 mA h. Our experimental results demonstrate multi-environment locomotion, including crawling on the land, crawling on the underwater floor, swimming on the water surface, and bimodal buoyancy adjustment to submerge underwater or resurface. These findings show the potential of shape morphing to create versatile and energy efficient robotic platforms suitable for diverse environments.","url":"https://doi.org/10.48550/arxiv.2511.09885","authors":["Singh, Shashwat","Si, Zilin","Temel, Zeynep"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2511.09885","addedAt":"2026-08-31T06:34:16.227Z","updatedAt":"2026-08-31T06:34:16.227Z"},{"id":"doi:10.1016/j.ifacol.2025.09.336","name":"Robotic Bin Picking with Adaptive Detection Time and Multi-Gripper Coordination","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.ifacol.2025.09.336","authors":["Jakob Marolt","Primož Bencak","Suhaib Mambayil","Tone Lerher"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-27T21:53:07Z","doi":"10.1016/j.ifacol.2025.09.336","addedAt":"2026-08-31T06:34:16.414Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1007/bf00126072","name":"Optimal path planning including forces at the gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/bf00126072","authors":["F.

A deep learning approach is proposed, leveraging convolutional neural networks (CNNs) to classify grasp outcomes from visual input. The model is trained on a custom dataset of images captured during robotic harvesting trials and optimized to detect subtle variations in gripper shape and fruit contact. The integration of soft metamaterial-based grippers with computer vision algorithms enables a robust, non-invasive grasp assessment pipeline, contributing toward fully autonomous and adaptive fruit-picking robots. The proposed method achieved an accuracy of 94.0% for correct grasps, 91.5% for failed grasps, and 95.9% for no-object cases, with an average inference time of 87 ms (ranging from 75 to 98 ms).","url":"https://doi.org/10.35633/inmateh-77-71","authors":["Florin Bogdan MARIN","Mihai Gabriel MATACHE","Mihaela MARIN","Gheorge GURAU","Robert CRISTEA","Andrei TĂNASE"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-10T09:03:08Z","doi":"10.35633/inmateh-77-71","addedAt":"2026-08-31T06:34:16.414Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/icra.2017.7989332","name":"Optimal design of a soft robotic gripper with high mechanical advantage for grasping irregular objects","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2017.7989332","authors":["Chih-Hsing Liu","Chen-Hua Chiu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-07-25T21:44:28Z","doi":"10.1109/icra.2017.7989332","addedAt":"2026-08-31T06:34:16.414Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.4271/2025-28-0145","name":"Fabrication and Analysis of Pneumatically Actuated Soft Robotic Gripper with Negative Pressure","source":"crossref","abstract":"&lt;div class=\"section abstract\"&gt;&lt;div class=\"htmlview paragraph\"&gt;Soft-bending actuators are gaining considerable attention in robotics for handling delicate objects and adapting to complex shapes, making them ideal for biomimetic robots.

Most soft robotic grippers, like their hard counterparts, require actuation to maintain a grip on an object. Here, we present a passive, soft robotic gripper that requires power to open and close but not to maintain a grip, which can be problematic in environments with limited energy availability (e.g. solar or battery power). Passive grip, by not requiring power to maintain grip on an object, provides a unique and safe alternative to energy-limited or energy-scarce environments. The Tufts Passive Gripper was inspired by the passive grip of the Manduca sexta and the simplicity of the Fin Ray® Effect. The gripper can be three-dimensional printed as one part on a multimaterial three-dimensional printer and only requires four additional steps to install the motor/tendon actuation mechanism. The gripper was capable of picking up over 40 common household objects, including a tissue, a pen, silverware, a needle, a stapler, a cup, and so on. The maximum load a gripper could hold when oriented perpendicular and parallel to the ground was 530 g (1 lb) and 240 g (0.5 lb), respectively.","url":"https://doi.org/10.1177/1729881417721155","authors":["Whitney Crooks","Shane Rozen-Levy","Barry Trimmer","Chris Rogers","William Messner"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-07-26T09:05:25Z","doi":"10.1177/1729881417721155","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/70.938389","name":"Scheduling in dual gripper robotic cells for productivity gains","source":"crossref","abstract":"","url":"https://doi.org/10.1109/70.938389","authors":["S.P.

This intrinsically links the bending angle and bending force in a way that made SMA-based soft grippers have relatively poor performance versus other types of soft actuators. In this work, the use of free-sliding SMA wires as tendons for soft actuation is presented that enables large increases in the bending angle and bending force of the actuator by decoupling the length of the matrix and the length of the SMA wires while also allowing for the compact packaging of the driving SMA wires. Bending angles of 400° and tip forces of 0.89 N were achieved by the actuators in this work using a tendon length up to 350 mm. The tendons were integrated as a compact module using bearings that enables the actuator to easily be implemented in various soft gripper configurations. Three fingers were used either in an antagonistic configuration or in a triangular configuration and the gripper was shown to be capable of gripping a wide range of objects weighing up to 1.5 kg and was easily installed on a robotic arm. The maximum pulling force of the gripper was measured to be 30 N.","url":"https://doi.org/10.1038/s41598-019-47794-1","authors":["Ji-Hyeong Lee","Yoon Seop Chung","Hugo Rodrigue"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-08-02T07:19:54Z","doi":"10.1038/s41598-019-47794-1","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/mra.2026.3693142/mm3","name":"Toward a Soft Robotic Gripper Integrating High Force Grasping and Dexterous Manipulation: The SOFRo Gripper_supp6-3693142.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mra.2026.3693142/mm3","authors":["Dongjun Shin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-08T19:50:30Z","doi":"10.1109/mra.2026.3693142/mm3","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/aim55361.2024.10637196","name":"Perception-Driven Robotic Manipulation for Packaging Stack of Envelopes: Gripper Design and Manipulation Strategies","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim55361.2024.10637196","authors":["Rohith Venkataramanan","Zhaoyuan Ma","Jing Xiao","Siavash Farzan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-22T17:52:35Z","doi":"10.1109/aim55361.2024.10637196","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/iros.2015.7353690","name":"Monolithic fabrication of sensors and actuators in a soft robotic gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros.2015.7353690","authors":["R.

To create proper gripper adaptability, intelligent gripper design is required to improve the sensibility and processing capability of the end-effectors. This will allow for grippers to perform effective decision-making and optimize production. This paper suggests a methodology that includes a step-by-step design process for an intelligent gripper and discusses how to develop intelligence utilizing key components of Industry 4.0 (Internet of Things, machine learning, and cloud manufacturing).

The system was tested both in laboratory simulations and real-world field conditions, with a focus on achieving high planting accuracy, reducing seedling damage, and enhancing overall operational efficiency. The implementation of Proportional-Integral-Derivative (PID) control and advanced image processing algorithms, such as Convolutional Neural Networks (CNN), allowed the gripper to perform with superior precision in dynamic environments typical of robotic contests. Experimental results demonstrated significant improvements in planting depth accuracy, seedling survival rates, and operational speed compared to traditional methods, highlighting the system’s potential for both competitive and practical agricultural applications.

While the shape morphing of the fingers is cable-driven, the stiffness variation is enabled by layer jamming. The inherent flexibility makes compliant gripper suitable for tasks such as grasping soft and irregular objects. However, their relatively low load capacity due to intrinsic compliance limits their applications. Variable stiffness robotic grippers have the potential to address this challenge as their stiffness can be tuned on demand of tasks. In our design, the compliant backbone of finger is made of 3D-printed PLA materials sandwiched between thin film materials. The workflow of the robotic gripper follows two basic steps. First, the compliant skeleton is driven by a servo motor via a tension cable and bend to a desired shape. Second, upon application of a negative pressure, the finger is stiffened up because friction between contact surfaces of layers that prevents their relative movement increases. As a result, their load capacity will be increased proportionally. Tests for stiffness of individual finger and load capacity of the robotic gripper are conducted to validate capability of the design. The results showed a 180-fold increase in stiffness of individual finger and a 30-fold increase in gripper’s load capacity.","url":"https://doi.org/10.1115/1.4047156","authors":["Yuan Gao","Xiguang Huang","Ishan Singh Mann","Hai-Jun Su"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-05-10T09:14:32Z","doi":"10.1115/1.4047156","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.5772/5653","name":"Kinematic Design of a Radius-Variable Gripper with 1-D.O.F.

Conventional grippers fail in situations involving inconsistency in force application, slippage, or unintended damage when handling delicate or irregularly shaped objects. While computer vision and machine learning algorithms have been introduced to enhance gripping precision, their need for extensive training sets and computational expenses limit real-time responsiveness in manufacturing environments. We propose a novel scanner-based robotic gripping system that integrates real-time 3D object modeling with an adaptive gripping scheme to mitigate such limitations. The configuration employs a seven-degree-of-freedom (7-DOF) Universal Robot to perform a 360-degree rotation scan to construct an exact 3D model of the object of interest. The Python-based algorithm monitors the created model and calculates the optimal grasping position and orientation for a biomimetic, human-hand-resembling 3D-printed robot gripper. The system’s pre-trained algorithm dynamically compensates for the force applied to the grip, considering object weight, to resist slippage and risk of structural damage. This new solution significantly enhances grasp stability and variability, offering a robust and effective solution for precision handling, e-commerce packaging, and industrial automation tasks in unstructured environments.","url":"https://doi.org/10.1115/imece2025-166009","authors":["Saquib Shahriar","Wenhua Yang","Chang Duan","Jaejong Park"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-02-23T16:47:30Z","doi":"10.1115/imece2025-166009","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1007/978-981-95-1657-5_8","name":"Design and Experimental Validation of a Cable-Driven Continuum Manipulator and Soft Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-95-1657-5_8","authors":["Xiang Zhang","Kangjia Fu","Xuesong Wu","Hongwei Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-01-02T01:15:04Z","doi":"10.1007/978-981-95-1657-5_8","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1002/aisy.201970032","name":"Toward a Smart Compliant Robotic Gripper Equipped with 3D‐Designed Cellular Fingers","source":"crossref","abstract":"","url":"https://doi.org/10.1002/aisy.201970032","authors":["Manpreet Kaur","Woo Soo Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-07-24T02:22:53Z","doi":"10.1002/aisy.201970032","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/rcar65431.2025.11139815","name":"Stiffness Evaluation of the Robotic Gripper for High-Speed Handling of the Deformable Object","source":"crossref","abstract":"","url":"https://doi.org/10.1109/rcar65431.2025.11139815","authors":["Yang Zhang","Saki Hashizume","Zhongkui Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-04T18:16:38Z","doi":"10.1109/rcar65431.2025.11139815","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/m2vip.2017.8211516","name":"Self morphing soft-robotic gripper for handling and manipulation of delicate produce in horticultural applications","source":"crossref","abstract":"","url":"https://doi.org/10.1109/m2vip.2017.8211516","authors":["Dean Venter","Steven Dirven"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-12-21T17:19:09Z","doi":"10.1109/m2vip.2017.8211516","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/inmic48123.2019.9022758","name":"Design and Compliance Control of a Robotic Gripper for Orange Harvesting","source":"crossref","abstract":"","url":"https://doi.org/10.1109/inmic48123.2019.9022758","authors":["Syed Humayoon Shah","Muhammad Arsalan","S G Khan","Muhammad Tufail Khan","Muhammad Shahab Alam"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-03-06T17:26:01Z","doi":"10.1109/inmic48123.2019.9022758","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/mepcon58725.2023.10462251","name":"Advanced Robotic Gripper Control System Using Intelligent Techniques","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mepcon58725.2023.10462251","authors":["Rufaidah Shehata","Hamdy M.

An artificial cellular finger is printed together with embedded pressure sensors on the fingertip to form a functional system in a single‐building process with the advantage of multi‐material 3D printing.

A novel linear series elastic actuated robotic gripper (LSEA-RG) is proposed to accomplish the aforementioned goals. The LSEA-RG has the ability to adaptively grasp objects with different shapes and sizes by grasping force control. First, the mechanical design, including the transmission scheme, the finger mechanism, and the actuating mechanism is presented. Subsequently, the kinematic analysis is performed to explore the transmission characteristic of the actuating displacement and force. Then a model-free control method based on the lookup functions of the kinematic transmission characteristics is presented to achieve the grasping range and force control. Finally, several grasping experiments are carried out based on the LSEA-RG prototype to evaluate the grasping performance. The results demonstrate that the presented grasping control method which based on the lookup functions is valid. The LSEA-RG could estimate the grasping force without the help of a fingertip force sensor and grasp objects with different shapes and hardness adaptively.","url":"https://doi.org/10.1115/1.4054609","authors":["Hongliang Hua","Zhenqiang Liao","Jingbo Zhao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-05-18T08:00:47Z","doi":"10.1115/1.4054609","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1007/11579427_105","name":"Adaptive Neuro-Fuzzy-Expert Controller of a Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/11579427_105","authors":["Jorge Axel Domínguez-López"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2005-11-18T08:43:01Z","doi":"10.1007/11579427_105","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/chicc.2016.7554316","name":"Universal soft pneumatic robotic gripper with variable effective length","source":"crossref","abstract":"","url":"https://doi.org/10.1109/chicc.2016.7554316","authors":["Yufei Hao","Zheyuan Gong","Zhexin Xie","Shaoya Guan","Xingbang Yang","Ziyu Ren","Tianmiao Wang","Li Wen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-09-21T16:04:17Z","doi":"10.1109/chicc.2016.7554316","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/remar.2018.8449831","name":"Adaptive Soft Robotic Gripper Based on Shape Morphing Compliant System","source":"crossref","abstract":"","url":"https://doi.org/10.1109/remar.2018.8449831","authors":["Andrija Milojevic","Sebastian Linss","Zarko Cojbasic","Heikki Handroos","Lauri Luostarinen","Lena Zentner"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-08-30T21:57:09Z","doi":"10.1109/remar.2018.8449831","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1016/j.rcim.2008.02.006","name":"Prediction of part orientation error tolerance of a robotic gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.rcim.2008.02.006","authors":["Matthew Wagner","John Morehouse","Shreyes Melkote"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-04-17T17:50:55Z","doi":"10.1016/j.rcim.2008.02.006","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/tmech.2024.3488817","name":"INDEX Gripper: Industrial Dexterous Robotic Gripper Capable of All-Orientational Object Manipulation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tmech.2024.3488817","authors":["Yooseong Lee","Joonho Lee","Dawoon Jung","Dong Il Park","Uikyum Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-20T14:01:25Z","doi":"10.1109/tmech.2024.3488817","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/lra.2022.3183756/mm1","name":"supp1-3183756.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2022.3183756/mm1","authors":["Gionata Salvietti"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-06-21T15:38:29Z","doi":"10.1109/lra.2022.3183756/mm1","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1016/j.aej.2021.06.045","name":"Design and analysis of a variable-stiffness robotic gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.aej.2021.06.045","authors":["Daniel Cardin-Catalan","Simon Ceppetelli","Angel P. del Pobil","Antonio Morales"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-07-01T01:08:52Z","doi":"10.1016/j.aej.2021.06.045","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/robio.2009.5420430","name":"Integrated gripper and cutter in a mobile robotic system for harvesting greenhouse products","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio.2009.5420430","authors":["Baozeng Jia","Anmin Zhu","Simon X.

This paper presents the design, analysis, and experimental evaluation of a novel reconfigurable four-finger robotic gripper. The proposed design incorporates two stationary fingers fixed to a circular base and two movable fingers repositioned and reoriented via a face gear mechanism, enabling multiple finger configurations to enhance adaptability. A single geared motor drives the opening and closing motions of all four fingers, simplifying the actuation mechanism. The robotic gripper was fabricated using 3D printing technology, ensuring cost-effective and precise manufacturing. Experimental tests were conducted to evaluate the robotic gripper’s reconfigurability and grasping performance across a range of objects, demonstrating its effectiveness in various configurations. Additionally, a closed-loop force control system was implemented to assess the grasping performance of a soft reconfigurable variant. Grasping force measurements were performed on three distinct objects, yielding a grasping curve that confirmed successful adaptation and secure handling. While the results validate the robotic gripper’s performance, further refinement of the control algorithm is recommended to optimize its capabilities. Compared to conventional three-finger designs, the proposed robotic gripper offers superior reconfigurability and adaptability, making it suitable for a broader range of industrial and research applications. The innovative face gear mechanism and modular design expand the robotic gripper’s functionality, positioning it as a versatile tool for advanced robotic manipulation tasks.","url":"https://doi.org/10.1017/s0263574725000700","authors":["Amr M.

This paper presents a design specifications template for wearable haptic interfaces, providing a structured approach to guide designers in addressing key parameters, including user functional needs, ergonomic requirements, and technical design data. A focused review of related technologies covering exoskeletons and wearable haptic devices, sensing technologies for touch, and recent robotic grippers was conducted to inform the template and identify gaps in current design practices. The template was validated using two complementary approaches. Theoretical validation involved mapping two existing wearable haptic systems to the template, revealing that coverage of user characteristics and functional requirements ranged from 25% to 37.5%, highlighting the need for more systematic consideration of human factors. Practical validation was performed by designing, fabricating, and evaluating a three‐finger wearable haptic device integrated with a robotic gripper, demonstrating improved coverage of user‐centered and technical parameters and confirming the template's practical applicability. Overall, the proposed framework provides a systematic, application‐driven methodology for developing reliable and scalable wearable haptic interfaces. By enabling designers to integrate human factors, device functionality, and technical specifications at the pre‐design stage, it supports improved human‐robot collaboration and sets a foundation for future standardized and adaptable haptic systems in teleoperation, rehabilitation, and robotic manipulation tasks.","url":"https://doi.org/10.1002/rob.70249","authors":["Amr M.

When designing a robotic gripper, it is necessary to take into account the variety of manipulated objects, the complexity of their identification and guidance of the manipulator in a complex natural environment with obstacles.

This study focuses on the material selection for the holder of flexible robotic grippers using fused deposition modelling. The holder plays a crucial role in ensuring a secure fit of the gripper’s fingers, which is essential for stable and precise object handling in bin picking applications. Testing specimens were fabricated following the ASTM D638-22 standard with a grid infill pattern at full density. Two different variants of Polyethylene Terephthalate Glycol and Acrylonitrile Styrene Acrylate were tested. Mechanical properties, including ultimate tensile strength, elongation at break, and Young’s modulus, were estimated using a universal testing machine. Results indicate that one variant of Polyethylene Terephthalate Glycol exhibited the highest tensile strength (40.54 MPa), making it suitable for applications requiring high mechanical strength and resistance to tensile loads, while Acrylonitrile Styrene Acrylate provided a balance between strength and flexibility. These results illustrate the comparison of materials and how material selection and infill density impact the mechanical performance of the holder, which contributes to a better choice of material. Future research will explore the influence of 3D printing temperatures, layer height and testing other infill patterns to further enhance the efficiency and reliability of materials used for robotic grippers in robotic manipulation.","url":"https://doi.org/10.31803/tg-20250411222835","authors":["Tone Lerher","Primož Bencak","Suhaib Ebrahim","Marko Motaln","Darko Hercog"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-07T11:49:38Z","doi":"10.31803/tg-20250411222835","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.623Z"},{"id":"doi:10.1115/1.4043686","name":"Self-Forcing Mechanism of the Braided Tube as a Robotic Gripper","source":"crossref","abstract":"Robotic grippers, which act as the end effector and contact the objects directly, play a crucial role in the performance of the robots. In this paper, we design and analyze a new robotic gripper based on the braided tube. Apart from deployability, a self-forcing mechanism, i.e., the holding force increases with load/object weight, facilitates the braided tube as a robotic gripper to grasp objects with different shapes, weights, and rigidities. First, taking a cylindrical object as an example, the self-forcing mechanism is theoretically analyzed, and explicit formulas are derived to estimate the holding force. Second, experimental and numerical analyses are also conducted for a more detailed understanding of the mechanism. The results show that a holding force increment by 120% is achieved due to self-forcing, and the effects of design parameters on the holding force are obtained. Finally, a braided gripper is fabricated and operated on a KUKA robot arm, which successfully grasps a family of objects with varying shapes, weights, and rigidities. To summarize, the new device shows great potentials for a wide range of engineering applications where properties of the objects are varied and unpredictable.","url":"https://doi.org/10.1115/1.4043686","authors":["Zufeng Shang","Jiayao Ma","Jinhua Li","Zemin Zhang","Guokai Zhang","Shuxin Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-05-06T13:22:19Z","doi":"10.1115/1.4043686","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.623Z"},{"id":"doi:10.1109/aim46323.2023.10196266","name":"Design and Prototyping of a Miniature Gripper with Decoupled Wrist and Rolling Capabilities for Robotic Surgery","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim46323.2023.10196266","authors":["Mohamed Sallam","Giuseppe Andrea Fontanelli","Fanny Ficuciello"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-02T17:35:59Z","doi":"10.1109/aim46323.2023.10196266","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.623Z"},{"id":"doi:10.1109/robio.2004.1521824","name":"Structural and Thermal Analysis of a Thermally Actuated Polymer Micro Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio.2004.1521824","authors":["Zhihua Liu","Yangjie Wei","Ho-Yin Chan","Wen Jung Li","Zaili Dong","Yuechao Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2005-10-24T14:41:07Z","doi":"10.1109/robio.2004.1521824","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.623Z"},{"id":"doi:10.1007/10992388_5","name":"Intelligent Neurofuzzy Control of a Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/10992388_5","authors":["J.A.

However, control architectures of the grasping force are still rare in common industrial grippers. In this context, one or more sensors (e.g., force or torque sensors) are necessary. However, the incorporation of such sensors might heavily affect the cost of the gripper, regardless of its type (e.g., pneumatic or electric). An alternative approach could be open-loop force control strategies. Hence, this work proposes an approach for optimizing the open-loop grasping force behavior of a robotic gripper. For this purpose, a specialized robotic gripper was built, as well as its mathematical model. The model was employed to predict the gripper performance during both static and dynamic force characterization, simulating grasping tasks under different experimental conditions. Both simulated and experimental results showed that by managing the mechanical properties of the finger–object contact interface (e.g., stiffness), the steady-state force variability could be greatly reduced, as well as undesired effects such as finger bouncing. Further, the object’s size is not required unlike most of the grasping approaches for industrial rigid grippers, which often involve high finger velocities.

A hierarchical control scheme is proposed based on a fuzzy controller for the force regulation of the gripper and proper grasping criteria, that can detect misplaced strawberries on the gripper or uneven distribution of forces. The design of the gripper and the controller are based on conducted experiments to measure the maximum gripping force and the required detachment force under a variety of detachment techniques. It is demonstrated that the hand motion for detaching the fruit from the stem has a significant role in the process because it can reduce the required force. By analysing those results a robotic gripper with pressure profile sensors is developed that demonstrates an efficiency comparable to the human hand for strawberry grasping. The designed gripper and fuzzy controller performance is tested with a considerable number of fresh fruits to demonstrate the effectiveness to the uncertainties of strawberry grasping.","url":"https://doi.org/10.1017/s0263574714001155","authors":["Fotios Dimeas","Dhionis V.

The function of the end-effector or robotic gripper is to allow the robotic arm to grasp and manipulate objects. The traditional hard robotic grippers are prone to poor gripping ability when grasping objects with irregular shape or in-ability to passively adjust force to delicate objects. Soft Robotic grippers were purposely designed to solve these disadvantages. In this work, a novel light weight robotic gripper based on grasping action of holding an object in between two strips of in-elastic flexible material under tensile force developed when pulled is hereby presented. Force analysis of the gripper was carried out as well as validation experiments. Analysis shows that the minimum pulling force to be exerted by the gripper on the grasping strips is directly proportional to the payload mass and the strips lengths. It is also inversely proportional to the coefficient of static friction between the payload-strips interface and the horizontal extent of the payload. Experimental results supported these observations. Moreover the predicted analytical values of gripper pulling force agreed reasonably with the empirically derived values. A proof of concept model of the gripper successfully grasps a 185g object.","url":"https://doi.org/10.36108/ujees/3202.50.0170","authors":["O. Olukayode,","K.O. Alawode","T.O. Ajewole","W.O.

They excel in manipulating delicate, irregularly shaped, and soft objects, surpassing the limitations of conventional grippers. However, effective control techniques for managing the grasping profile of SPGs are still under development. Simple on–off pressure control using a regulator valve is inadequate for delicate gripping with pneumatic robot grippers. To address this, a synergy pressure control system was implemented. In addition, a proportional–integral–derivative control technique, complemented by an unknown input observer, was devised to control the volume of the soft pneumatic robotic gripper, ensuring its alignment with the desired volume level. The simulation and experimental results provide substantial evidence of the effectiveness of the developed control technique and the unknown input observer in managing the volume and pressure of the gripper. Consequently, this breakthrough empowers precise and delicate gripping actions, enabling the handling of delicate objects such as tofu.","url":"https://doi.org/10.3390/robotics12040107","authors":["Gridsada Phanomchoeng","Patchara Pitchayawetwongsa","Nattaphat Boonchumanee","Saravut Lin","Ratchatin Chancharoen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-07-18T01:31:32Z","doi":"10.3390/robotics12040107","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.4018/978-1-6684-5381-0.ch004","name":"A Soft Robotic Gripper Material Study","source":"crossref","abstract":"Soft robots have gained superiority in outdoor applications compared to traditional robots today.

One of the parameters that determine the mechanical properties is the change of curing behavior. The choice of mixing technique, on the other hand, is very crucial since it affects the curing behavior. For this reason, the effects of not only the additive but also the various mixing techniques on the material behavior and curing time were reported as a result of the experiments.

Three main objectives were pursued: (1) developing a soft silicone gripper as an alternative to expensive and rigid steel grippers, enabling safe and precise handling of delicate or irregular objects such as fruits, glassware, and irregular shapes; (2) fabricating a continuum manipulator arm with robotic joints inspired by vertebrae, allowing for smooth, non-linear motion and more excellent maneuverability compared to traditional rigid arms, enabling access to hard-to-reach areas; and (3) integrating the compliant gripper with the continuum manipulator and implementing a control system for the soft gripper and remote bending arm using a microcontroller. The soft gripper, manipulator arm vertebrae, and other components were fabricated using 3D printing with PLA material for the molds. The gripper construct used hyperelastic silicone (Ecoflex 00.30). The continuum manipulator achieved a higher degree of freedom and mobility, while simulations and experiments validated the design’s effectiveness. The comparison shows that the close agreements differ by only 2.5%. In practical experiments involving lifting objects, the gripper was able to carry items with a greater mass. The proposed soft, integrated robotic system outperformed traditional rigid approaches, offering safe and flexible handling capabilities in unstructured environments. The nature-inspired design enabled a compliant grip and enhanced maneuverability, making it suitable for various applications requiring dexterous manipulation of delicate or irregularly shaped objects.","url":"https://doi.org/10.3390/act13080298","authors":["Shakir Qaddoori Fenjan","Siavash Fathollahi Dehkordi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-06T11:54:19Z","doi":"10.3390/act13080298","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1080/00207549108930072","name":"Strategies for gripper design and selection in robotic assembly","source":"crossref","abstract":"","url":"https://doi.org/10.1080/00207549108930072","authors":["D.

While comprehensive motions can be achieved by sophisticated soft robots, multiple coordinated pneumatic controls are usually required to achieve even the simplest motions. Furthermore, most soft robotics are lacking the ability to sense the environment and provide feedback to the pneumatic control system. In this work, we design a twining plant inspired soft-robotic spiral gripper that requires only one single pneumatic control to perform the twining motion and to firmly hold onto a target object. The soft-robotic spiral gripper has an embedded high-birefringence fiber optic twisting sensor to provide critical information, including twining angle, presence of external perturbation, and physical parameter of the target object. Furthermore, finite element analyses (FEA) in parametric studies of the spiral gripper are performed for module design optimization. The unique single pneumatic channel design enables easy manipulation of the soft spiral gripper with a maximum of 540° twining angle and allows a firm grip of a target object as small as 1-mm in diameter. The embedded fiber optic sensor provides useful information of the target object as well as the twining angle of the soft robotic spiral gripper with high twining angle sensitivity of 0.03nm. The unique fiber-optic sensor embedded single-channel pneumatic spiral gripper that is made from non-toxic silicone rubber allows parallel and soft gripping of elongated objects located in a confined area, which is an essential building block for twining and twisting motions in soft robot.","url":"https://doi.org/10.1364/oe.408910","authors":["Mei Yang","Liam Paul Cooper","Ning Liu","Xianqiao Wang","Mable P.

Objects with different shapes, sizes and weights were successfully lifted with selected gripper configurations. The results showed that grain size and grain compressibility both affect the performance of the gripper. It was demonstrated that in order to efficiently lift heavy objects with granular jamming, the granular material has to be compressed sufficiently.

It is a big problem for soft grippers to solve low load gripping and low grasping success rate. For solving these problems, a kind of enclosed structure soft gripper expansion type (ET) is proposed. The ET is driven by hydraulic or pneumatic system with stable force and high reliability. The ET is proposed based on an enclosed grasping mechanism, and based on the biomimetic underwater swallowing design method. The ET which has both advantages of economy and flexibility, self-adaptive grasps through negative pressure and positive pressure. The ET achieves the modular, mobile and adaptive grasping ability. The ET classifies as gripper A (GA) and gripper B (GB). GA has more load capacity, and GB can grab larger irregular objects. The maximum load that ET achieving is 30 N, which is able to reliably grasp objects and hold them with a force several times their weight.

When reducing the gap between the ring inner wall of the soft gripper and the target object, it further reduces the gap through pressure in case of emergencies, so as to better grip force, so that the gripper has a better fault tolerance rate and inclusiveness when it holds the object.","url":"https://doi.org/10.1115/fpmc2023-111431","authors":["Yaxin Wu","He Xu","Siqing Chen","Qiandiao Wei","Xiao Xiong","Hao Yin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-11-17T11:53:48Z","doi":"10.1115/fpmc2023-111431","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1109/etfa46521.2020.9212163","name":"An adaptive robotic grasping with a 2-finger gripper based on deep learning network","source":"crossref","abstract":"","url":"https://doi.org/10.1109/etfa46521.2020.9212163","authors":["Wafae SEBBATA","Mourad A.

The current approaches are aimed at the automated design of monolithic gripper fingers, which have to be manufactured additively or by machining. This paper describes a novel approach for the automated design of gripper fingers. The motivation for this work stems from the increasing demand for flexible, adaptable handling systems in various industries in response to the increasing individualization of products as well as the increasing volatility in the markets. Based on the CAD data of the handling objects, the most suitable configuration of gripper fingers can be determined from the existing modules of a construction kit for the respective handling object, which can significantly reduce the provisioning time for new gripper fingers. It can be shown that gripper fingers can be effectively configured for a variety of objects and two different grippers, increasing flexibility in industrial handling processes.","url":"https://doi.org/10.3390/machines11080804","authors":["Marco Friedmann","David Klüpfel","Christian Frech","Mijian Liu","Jan Hauf","Gaole Li","Christian Friedrich","Jürgen Fleischer"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-04T09:28:34Z","doi":"10.3390/machines11080804","addedAt":"2026-08-31T06:34:16.415Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1016/j.eswa.2012.07.076","name":"Adaptive neuro fuzzy estimation of underactuated robotic gripper contact forces","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.eswa.2012.07.076","authors":["Dalibor Petković","Nenad D.

To address this problem, we have developed a novel quadruped system augmentation: A lightweight, soft, and compliant tendon-actuated robotic tail mounted on a quadruped robot. The tail features a hollow, flexible backbone and a tendon-actuated soft gripper that enables the robot to pick up sampling tissues, swab contaminated surfaces, and release the tissues at designated collection locations for subsequent beryllium analysis. To enable intuitive teleoperation, a closed-form kinematic model and a singularity-robust task-space controller are developed. Experimental results demonstrate that gripper actuation has a negligible effect on robot shape, while common-mode tendon actuation provides an effective mechanism for stiffness modulation and preload control. Furthermore, experimental validation indicates that the proposed kinematic model provides a suitable basis for real-time task-space control. The proposed system combines the agility of legged locomotion with the compliance of soft robotic manipulation, enabling the complete contamination-survey procedure to be performed without human exposure.

Unlike many continuum robots that are single-purpose and costly, the proposed design prioritizes customizability, rapid assembly, and low cost while enabling high curvature and enhanced distal compliance through geometric tapering, thereby supporting a broad range of compliant robotic inspection and manipulation tasks. We develop a generalized forward kinetostatic model of the tapered backbone based on Cosserat rod theory using a Newtonian approach, extending existing tendon-actuated Cosserat rod formulations to explicitly account for spatially varying backbone cross-sectional geometry. The model captures the graded stiffness profile induced by the tapering and enables systematic exploration of the configuration space as a function of the geometric design parameters. Specifically, we analyze how the backbone taper angle influences the robot's configuration space and manipulability. The model is validated against motion capture data, achieving centimeter-level shape prediction accuracy after calibrating Young's modulus via a line search that minimizes modeling error.

During fine-tuning, however, action supervision applies equally across all timesteps, without structured supervision on which manipulation stage the robot is in or what the next gripper-event target should be. This causes failures to concentrate around challenging gripper-event transitions. To address this, we propose StaKe, a plug-in auxiliary supervision framework that automatically derives two complementary signals from demonstration gripper states without manual annotation: a stage classifier that identifies the current manipulation stage, and a keyframe predictor that estimates the target joint action at the next gripper transition. Both are modeled as lightweight auxiliary heads that enrich the learned representations during training, while leaving the base VLA policy architecture and inference loop unchanged. Experiments on bimanual simulation and single-arm Franka real-robot tasks show that StaKe consistently improves success rates (relative gains of 14% and 56%, respectively), with larger improvements on longer-horizon tasks that involve more gripper-event transitions. Ablation studies validate each design choice, and qualitative analysis confirms that the learned representations faithfully track manipulation stages.

To enable robots to work in a human-centric environment, it is desirable to endow robotic hands with human-like capabilities for grasping and object manipulation. However, due to its inherent complexity and inevitable model uncertainty, robotic grasping and manipulation remains a challenge. This thesis focuses on grasp adaptation in the face of model and sensing uncertainties: Given an object whose properties are not known with certainty (e.g., shape, weight and external perturbation), and a multifingered robotic hand, we aim at determining where to put the fingers and how the fingers should adaptively interact with the object using tactile sensing, in order to achieve either a stable grasp or a desired dynamic behaviour. A central idea in this thesis is the object-centric dynamics: namely, that we express all control constraints into an object-centric representation. This simplifies computa- tion and makes the control versatile to the type of hands. This is an essential feature that distinguishes our work from other robust grasping work in the literature, where generating a static stable grasp for a given hand is usually the primary goal. In this thesis, grasp adaptation is a dynamic process that flexibly adapts the grasp to fit some purpose from the objectâ s perspective, in the presence of a variety of uncertainties and/or perturbations. When building a grasp adaptation for a given situation, there are two key problems that must be addressed: 1) the problem of choosing an initial grasp that is suitable for future adaptation, and more importantly 2) the problem of design- ing an adaptation strategy that can react adequately to achieve desired behaviour of the grasped object. To address challenge 1 (planning a grasp under shape uncertainty), we propose an approach to parameterizing the uncertainty in object shape using Gaussian Processes (GPs) and incorporate it as a constraint into contact-level grasp planning. To realize the planned contacts using different hands interchangeably, we further develop a prob- abilistic model to predict the feasible hand configurations, including hand pose and finger joints, given the desired contact points only. The model is built using the con- cept of Virtual Frame(VF), and it is independent from the choice of hand frame and object frame. The performance of the proposed approach is validated on two differ- ent robotic hands, an industrial gripper (4 DOF Barrett hand) and a humanoid hand (16 DOF Allegro hand) to manipulate objects of daily use with complex geometry and various texture (a spray bottle, a tea caddy, a jug and a bunny toy). In the second part of this thesis, we propose an approach to the design of adapta- tion strategy to ensure grasp stability in the presence of physical uncertainties of objects(object weight, friction at contacts and external perturbation). Based on an object-level impedance controller, we first design a grasp stability estimator in the object frame using the grasp experience and tactile sensing. Once a grasp is predicted to be unstable during online execution, the grasp adaptation strategy is triggered to improve the grasp stability, by either changing the stiffness at finger level or relocating the position of one fingertip to a better area.","url":"https://doi.org/10.5075/epfl-thesis-6908","authors":["Li, Miao"],"tags":["Grasp Adaptation","Object-level Impedance Control","Dexterous Manipulation","Tactile Sensing","Learning by Demonstration"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2016","doi":"10.5075/epfl-thesis-6908","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.5075/epfl-thesis-6855","name":"Functional Soft Robotic Actuators Based on Dielectric Elastomers","source":"datacite","abstract":"Dielectric elastomer actuators (DEAs) are a promising soft actuator technology for robotics. Adding robotic functionalities--folding, variable stiffness, and adhesion--into their actuator design is a novel method to create functionalized robots with simplified actuator configurations. We first propose a foldable actuator that has a simple antagonistic DEA configuration allowing bidirectional actuation and passive folding. To prove the concept, a foldable elevon actuator with outline size of 70 mm × 130 mm is developed with a performance specification matched to a 400 mm wingspan micro air vehicle (MAV) of mass 130 g. The developed actuator exhibits actuation angles up to ± 26 ° and a torque of 2720 mN·mm in good agreement with a prediction model. During a flight, two of these integrated elevon actuators well controlled the MAV, as proven by a strong correlation of 0.7 between the control signal and the MAV motion. We next propose a variable stiffness actuator consisting of a pre-stretched DEA bonded on a low-melting-point alloy (LMPA) embedded silicone substrate. The phase of the LMPA changes between liquid and solid enabling variable stiffness of the structure, between soft and rigid states, while the DEA generates a bending actuation. A proof-of-concept actuator with dimension 40 mm length × 10mm width × 1mm thickness and a mass of 1 g is fabricated and characterized. Actuation is observed up to 47.5 ° angle and yielding up to 2.4 mN of force in the soft state. The stiffness in the rigid state is ~90 × larger than an actuator without LMPA. We develop a two-finger gripper in which the actuators act as the fingers. The rigid state allows picking up an object mass of 11 g (108 mN), to be picked up even though the actuated grasping force is only 2.4 mN. We finally propose an electroadhesion actuator that has a DEA design simultaneously maximizing electroadhesion and electrostatic actuation, while allowing self-sensing by employing an interdigitated electrode geometry. The concept is validated through development of a two-finger soft gripper, and experimental samples are characterized to address an optimal design. We observe that the proposed DEA design generates 10 × larger electroadhesion force compared to a conventional DEA design, equating to a gripper with a high holding force (3.5 N shear force for 1 cm^2) yet a low grasping force (1 mN). These features make the developed simple gripper to handle a wide range of challenging objects such as highly-deformable water balloons (35.6 g), flat paper (0.8 g), and a raw chicken egg (60.9 g), with its lightweight (1.5 g) and fast movement (100 ms to close fingers).

However, existing designs struggle to grasp feature-rich objects with high topological variability, including gears with sharp tooth profiles on automotive assembly lines, corals with fragile protrusions, or vegetables with irregular branching structures like broccoli. Unlike simple geometric primitives such as cubes or spheres, feature-rich objects lack a clear \"optimal\" contact surface, making them both difficult to grasp and susceptible to damage. Safe handling of such objects therefore requires specialized soft grippers whose morphology is tailored to the object's features. Topology optimization offers a promising approach for producing specialized grippers, but its utility is limited by the need for pre-defined load cases. For soft grippers, these loads arise from hundreds of unpredictable gripper-object contact forces during grasping and are unknown a priori. To address this problem, we introduce SimTO, a two-stage, simulation-driven topology optimization framework that automatically extracts load cases from a dynamic, contact-rich grasping simulation before performing classical topology optimization, eliminating the need for manual load specification. Given an arbitrary feature-rich object, SimTO produces highly customized soft grippers with fine-grained morphological features tailored to the object geometry. Physical experiments confirm that our specialized grippers achieve higher grasp forces than a generalist design produced by conventional topology optimization methods, while numerical experiments show that they achieve high grasp success rates across varying object poses and strong generalization to a set of unseen objects.","url":"https://doi.org/10.48550/arxiv.2601.19098","authors":["Enkera, Kurt","Pinskier, Josh","Gallagher, Marcus","Howard, David"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2601.19098","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.48550/arxiv.2606.12954","name":"Towards Reliable Sequential Object Picking in Clutter: The Runner-up Solution to RGMC 2025","source":"datacite","abstract":"As a long-standing challenge in robotic manipulation, stable and efficient grasping in cluttered environments is of great importance in industrial settings. While recent studies have achieved relatively high success rates in grasping from clutter, there remain few mature solutions for more demanding tasks such as sequential object search and sorting. This work addresses sequential object picking in cluttered environments based on the Cluttered Environment Picking Benchmark (CEPB) and presents our solution to the Pick-in-Clutter track of the 10th Robotic Grasping and Manipulation Competition (RGMC) at ICRA 2025. The task poses several key challenges. First, it requires robust and collision-aware grasping with high success rates across a diverse set of objects, including both rigid and deformable ones. Second, it demands efficient search for target objects, which places stringent requirements on the decluttering and searching strategies of the solution. To address the above challenges, we design an integrated hardware-software pipeline that combines object recognition, decluttering, and multi-modal grasping. The main contributions include the hardware design of a multifunctional gripper and novel representations for object distribution and occlusion relationships in cluttered space. This pipeline enables efficient recognition, search, and sequential grasping of objects in clutter, demonstrating strong performance in both laboratory tests and competition scenarios, and ultimately achieving second place in the Pick-in-Clutter track of the RGMC 2025.","url":"https://doi.org/10.48550/arxiv.2606.12954","authors":["Yu, Wei","Zhang, Xidan","Zheng, Ziyi","Kong, Weijie","Dong, Huixu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.12954","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:26.468Z"},{"id":"doi:10.82419/415","name":"Toward Task Generalization in Vision-Language-Action Models through Structured Visual Goal Conditioning","source":"datacite","abstract":"Large vision-language models' semantic reasoning capabilities are combined with robotic control in Vision-Language-Action (VLA) models to enable policies that obey natural language instructions in a variety of manipulation tasks. There is, however, a persistent gap between what these models comprehend and what they can consistently perform: policies often correctly interpret task intent but fail during physical manipulation, especially under distribution shifts in object appearance, workspace layout, and scene composition. The goal representation itself is one contributing factor. While standard natural language instructions offer semantic flexibility, they also introduce spatial ambiguity that makes precise manipulation more difficult. To improve the generalization capabilities of VLA policies in pick-and-place tasks, this research investigates structured visual goal conditioning. The proposed approach derives per-timestep pixel-space UV coordinates of the target object through instance segmentation. cThese coordinates are then encoded as succinct language instructions. These instructions define the spatial goal location within the camera frame and the desired gripper action, rather than relying on unstructured language descriptions. This method distinguishes goal specification from object identity and appearance by directly linking task instructions to the policy's visual observation space. The complete pipeline was constructed and evaluated. NVIDIA Isaac Sim's simulation-driven data generation framework produced 9,500 expert demonstration episodes, incorporating detailed goal metadata and systematic scene randomization. These demonstrations served as the training data for SmolVLA, a VLA model comprising 450 million parameters, which was trained using UV-conditioned instructions. For closed-loop policy evaluation, a dual-process deployment architecture overcomes the incompatible dependencies between the simulation runtime and the training framework. Three conditions of increasing distributional difficulty are used to assess the trained policy: visual generalization with new object shapes, distractors, and camera perturbations; clean task transfer with zero-shot stacking and sorting; and training-distribution replay with matched clutter statistics. Distance-based behavioral analysis suggests that UV conditioning may elicit goal-directed approach behavior across all experimental conditions. In particular, the end-effector appears to reduce its distance to the target by approximately 26–32 cm during the initial approach phase, even though the policy does not successfully complete the task under any condition. A consistent failure mode is observed in the form of a vertical bias, where the end-effector remains several centimeters above the target object, preventing successful grasp contact. One possible explanation for this behavior is the absence of explicit depth information in the 2D pixel-space goal representation, which may limit accurate vertical alignment. Cross-condition trends indicate that performance tends to be higher in training-distribution scenes compared to geometrically simpler but distributionally mismatched clean scenes, and may degrade as distributional shift increases. Notably, some episodes under generalization conditions approach the median performance observed in training-distribution settings, suggesting that UV conditioning may retain some robustness under mild perturbations. Overall, these results point toward the potential benefit of incorporating explicit depth information to enable more reliable task completion. They also suggest that pixel-space goal conditioning can provide useful lateral spatial grounding for VLA policies, though further validation is needed.","url":"https://doi.org/10.82419/415","authors":["Alghaithi, Maitha Hamdan Saeed"],"tags":["Robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.82419/415","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.48550/arxiv.2606.10244","name":"YUBI: Yielding Universal Bidigital Interface for Bimanual Dexterous Manipulation at Scale","source":"datacite","abstract":"We introduce Yielding Universal Bidigital Interface (YUBI), a finger-aligned gripper designed to enable intuitive, ergonomic, and scalable data collection for bimanual dexterous manipulation.

While many robotic systems simplify contact as a small set of discrete points, real manipulation often depends on distributed contact patches whose pressure, friction, micro-slip, and vibration-rich interactions strongly influence object motion. These interactions are difficult to represent with standard rigid-body models, are often visually occluded at the moment of contact, and can generate high-frequency signals that are challenging to simulate but informative to sense. This dissertation studies how robots can model, act through, and perceive such contact interactions for dexterous manipulation. To model patch-contact mechanics, this dissertation first presents a dual asymmetric limit surface model for planar manipulation. The model captures stick-slip boundaries induced by coupled frictional contacts and enables stable open-loop planning for slippage-free planar sliding on both horizontal and inclined surfaces. To act through contact, this dissertation then introduces Vib2Move, a vibration-based in-hand manipulation framework that uses fingertip micro-vibrations to modulate effective friction and drive object reconfiguration in free space with a simple parallel gripper. To perceive contact under occlusion and ambiguity, this dissertation next proposes VA2Contact, a visual-auditory method for estimating extrinsic object-environment contact by combining global visual information with local active-audio cues through a real-to-sim audio hallucination pipeline. Finally, this dissertation presents Sound of Touch, an active acoustic tactile sensing approach based on continuously excited tensioned strings, where contact location, normal force, and slip are inferred from structured vibration responses. Together, these contributions establish physically grounded methods for understanding and exploiting friction-rich, vibration-rich contact in robotic manipulation. By advancing beyond simplified point-contact abstractions, this dissertation shows how contact mechanics and vibration can be leveraged not only as sources of complexity, but also as useful structure for more capable and contact-aware dexterous manipulation.","url":"https://doi.org/10.7302/dspace/29771","authors":["Yi, Xili"],"tags":["dexterous manipulation","multi-modal sensing","machine learning","Engineering (General)","Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.7302/dspace/29771","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.48550/arxiv.2605.17929","name":"TacSE3: Equivariant SE(3) Motion Estimation from Low-Texture Visuotactile Images for In-Gripper Tracking and Compensation","source":"datacite","abstract":"Robotic in-hand manipulation requires reliable object-motion tracking under frequent visual occlusion, yet low-texture visuotactile images provide few stable correspondences for conventional image- or geometry-matching methods.

Additional analysis indicates that phase-level supervision and multi-frame directional cues make the student less sensitive to noisy teacher actions, such as erroneous high-frequency gripper changes. Overall, VLA-AD demonstrates that offline semantic guidance from VLMs can substantially improve the efficiency, robustness, and deployability of VLA policy distillation.","url":"https://doi.org/10.48550/arxiv.2605.16241","authors":["Shi, Jin","Zhang, Brady","Lu, Yishun"],"tags":["Computer Vision and Pattern Recognition (cs.CV)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2605.16241","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.48550/arxiv.2605.14526","name":"DiffPhD: A Unified Differentiable Solver for Projective Heterogeneous Materials in Elastodynamics with Contact-Rich GPU-Acceleration","source":"datacite","abstract":"Differentiable simulation of soft bodies is a foundation for system identification, trajectory optimization, and Real2Sim transfer.

We present DiffPhD, a unified GPU-accelerated differentiable Projective Dynamics framework for heterogeneous materials that tackles these intertwined challenges simultaneously. Our key insight is a careful integration of: (i) stiffness-aware projective weights to embed heterogeneity into the global system; (ii) trust-region eigenvalue filtering lifted to the backward pass for stable hyperelastic gradients and a type-II Anderson Acceleration scheme with dual-gate convergence to stabilize forward iteration under large stiffness contrasts; and (iii) a unified GPU pipeline that reuses a single sparse factor across forward, backward, and contact computations, with stiffness-amplified Rayleigh damping folded into the same factor for heterogeneity-aware dissipation at zero recurring cost. DiffPhD achieves strict gradient accuracy while delivering up to an order-of-magnitude speedup over prior differentiable solvers on heterogeneous, hyperelastic, contact-rich benchmarks. Crucially, this speedup does not come at the cost of stability: DiffPhD remains convergent on stiffness contrasts up to 100x where prior PD solvers degrade. This unlocks end-to-end gradient-based optimization on regimes previously bottlenecked by either solver fragility or per-iteration cost -- shell--joint composite creatures, soft characters wielding stiff weapons, and soft-gripper robotic manipulation -- all handled within a single forward--backward pass.","url":"https://doi.org/10.48550/arxiv.2605.14526","authors":["Lai, Shih-Yu","Tien, Sung-Han","Huang, Jui-I","Tseng, Yen-Chen","Chiu, Yi-Ting","Luo, Siyuan","Zeng, Ziqiu","Shi, Fan","Chen, Peter Yichen","Liu, Tiantian","Liu, Yu-Lun","Chen, Bing-Yu"],"tags":["Graphics (cs.GR)","Distributed, Parallel, and Cluster Computing (cs.DC)","Numerical Analysis (math.NA)","Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences","FOS: Mathematics","FOS: Mathematics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2605.14526","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.48550/arxiv.2603.11383","name":"Vision-Based Hand Shadowing for Robotic Manipulation via Inverse Kinematics","source":"datacite","abstract":"Teleoperation of low-cost robotic manipulators remains challenging due to the difficulty of retargeting human hand motion to robot joint commands.

Even though the approaches investigated here are quite general, the techniques are developed with respect to the specific application of flexible automation of a fish processing cell. Robotics and computer vision have been combined to produce useful results in a variety of applications. Vision guidance may be applied at least in two ways here. Cutting contours of fish could be generated off-line and these could be used to generate the reference signals for the cutting controller. Alternatively, cameras mounted on the cutter could be used to guide the cutter in real time. The present research concentrates on the first approach since the objective is to generate the cutting contour sufficiently fast to meet the process speed requirements. The complexity of the vision problem is eased to some extent by the fact that the object (fish) is already recognized, at least in a generic sense. Low-to-medium-level computer vision techniques involving image transformation, enhancement and analysis of basic features such as edges, regions, shape, colour and texture, are reasonably well established and widely applied. The application of these techniques to directly generate the cutting contour of an arbitrary fish would be computationally slow and unacceptable in terms of process speed requirements. The present research effort is directed at expediting vision-based generation of cutting contours through the use of model-based vision techniques. One of the goals of this research is to develop a knowledge-base and a model-base to support the complex feature extraction procedure. Use of low-level image analysis techniques to obtain non-complex features at high speeds from the fish images is a further goal, as this is related to the first goal. In the model-based approach, the fish models are generated using a representative database of measurements on fish. The data includes a cutting contour and some dimensional measurements which are referred to as attributes or features. The cutting contours are non-dimensionalized, transformed, and grouped into an appropriate number of models using a systematic grouping procedure. Each model contains a non dimensional cutting contour for the corresponding group of fish, and a set of attributes. In real-time operation, the measured attributes have to be matched to the model. The main contribution of this research is the methodology for the generation of rules for model matching or classification. The a priori probability distribution of attributes in each group is used to generate the rules for the model that corresponds to the group. Rules generated for all models are collected in a rule base and used for classification. A systematic method for integrating expert and heuristic knowledge is developed in order to improve the efficiency of the classification process. An extensive process of error analysis of the present methodology is also presented. The techniques developed in the present research were implemented in a prototype fish processing cell that is being developed in the Industrial Automation Laboratory. This cell consists of a vision station, a knowledge-based system, a robotic cutter, and a motorized conveyor unit. In a heading (head removal) operation, each fish on the conveyer is imaged at the vision station and the corresponding cutting contour is determined with the help of the knowledge-based system. This cutting contour is transformed into a drive signal for the robotic cutter. At the cutting station, a fish will be gripped and cut according to the trajectory generated for that particular fish. In the present prototype system, however, the robot draws the corresponding cutting contour on a board placed on the conveyor bed.

Deep Convolutional Neural Networks (DCNNs) are used to build a real-time end-to-end solution for the complex process of draping of the fiber-reinforced cut-pieces by conducting online visual inspection. The visual inspection will ultimately help with manufacturing of double-curved composite parts such as aircraft’s rear pressure bulkhead. The developed solution provides accurate and robust measurement without the need for expensive coordinate measuring machines (CMM) in the shop floor. The development of inspection software is completed in the following two stages. In stage I, after creating a hand-labeled visual dataset acquired from a fabric layup robotic system in the German Aerospace Center (DLR), a DCNN was designed, trained and tested for image classification. Then, the idea of combining images from multiple cameras for generalization of the designed model to different wrinkle properties and environments was evaluated. The proposed method employs computer vision techniques and Dempster-Shafer Theory (DST) to enhance wrinkle detection accuracy without the need for any additional hand-labeling or re-training of the model. By the application of the DST rule of combination, the overall wrinkle detection accuracy was greatly improved. In stage II, four state-of-the-art image segmentation DCNN models (DeepLab V3+, U-Net, Mask-RCNN, IC-Net) were evaluated to accurately identify the gripper, fabric, and any probable wrinkle on a dry fiber product. The results show using a DCNN model and transfer learning can lead to acceptable results while training on a small and inaccurately annotated dataset. Also, the impact of human annotation quality on the performance of DCNN models was evaluated by comparing two human-annotated datasets. Then, an approach for detection of wrinkles at the early stages of formation was developed and evaluated. Finally, the challenges of using synthetically generated data for training the models were assessed by conducting complementary experiments. The developed solution can be practically used for visual inspection of the draping process in composite manufacturing facilities. The presented method can be readily adopted to train DCNN models using other datasets and perform visual inspection tasks in different automated manufacturing processes.","url":"https://doi.org/10.14288/1.0389965","authors":["Djavadifar, Abtin"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.14288/1.0389965","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.14288/1.0344007","name":"Data-driven design of expressive robot hands and hand gestures : applications for collaborative human-robot interaction","source":"datacite","abstract":"Fast and reliable communication between human workers and robotic assistants (RAs) is essential for successful collaboration between these agents.

This thesis investigates the efficacy of nonverbal communication capabilities of robotic manipulators that have poseable, three-fingered end-effectors (hands). This work explores the extent to which different poses of a typical robotic gripper can effectively communicate instructional messages during human-robot collaboration. Within the context of a collaborative car door assembly task, a series of three studies were conducted. Study 1 empirically explored the type of hand configurations that humans use to nonverbally instruct another per- son (N=17). Based on the findings from Study 1, Study 2 examined how well human gestures with frequently used hand configurations were under- stood by recipients of the message (N=140).

Contributions of this work include the presentation of a set of hand configurations humans commonly use to instruct another person in a collaborative assembly scenario, as well as Recognition Rate and Recognition Confidence measures for the gestures that humans and robots expressed using different hand configurations. These experimental results indicate that most gestures are better recognized with a higher level of confidence when displayed with a posed robot hand.

The method is tailored for a two-fingered (antipodal) gripper, typically used in industry; however, it may be extended to other gripper types (i.e., three-fingered). The method is broken down into two stages: (1) offline generation of many high-quality, two-fingered grasps for a given part, and (2) online evaluation of these grasps in the context of the pile to determine a collision-free set of rated picks, and, ultimately, the most desirable pick. In evaluating grasps online, the effect of gripper finger clearance is considered to further minimize the risk of collision when executing the selected pick. Subsidiary contributions of this work include: (1) an automatic grasp-generation method to sample the space of all two-fingered grasps for the target part, (2) a metric function for evaluating grasps, and (3) a measure of the robustness of a grasp. The proposed method for pick selection is validated using stereo data of a real pile of parts. We compare the use of a small set of nominal grasps for pick selection (an approach typical in industry) to the use of an extensive evaluated grasp set generated using the proposed method. Our experimental results show that, in the majority of cases, the use of our method results in more valid and higher quality picks.","url":"https://doi.org/10.14288/1.0067664","authors":["Dupuis, Donna C."],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0067664","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.6084/m9.figshare.30790625.v1","name":"<b>Spanish voice command recognition</b>","source":"datacite","abstract":"Since voice detection varies by language, recognition algorithms are inherently sensitive to language-specific phonetics.

Through the lens of outer space and healthcare, this thesis explores the possibility for a symbiotic relationship between humans and assistive robots by improving training protocols and with enhanced sensor data processing. This relationship is explored through several technologies: 1) a telerobotic simulator for training; 2) a wearable robotic sensing system for the arm; 3) motor imagery control of an assistive robot; and 4) autonomous five-fingered grasping. Within these platforms, various sensor types are used including electroencephalography (EEG), electromyography (EMG), tendon-based sensing, and computer vision (CV). At the intersection of these robotic technologies and sensors, the key results include a novel metric based on Riemannian geometry indicating new EEG mental workload features, and EMG analysis showing which preprocessing methods are most promising for feature selection. In addition, EEG motor imagery training protocols can be improved through novel data augmentation strategies which reduce the amount of needed training data per person, and an adaptive task-based protocol which could more readily transfer into the real world. Finally, CV-based robotic hand shaping was shown to be a promising way to achieve a robust grasp with a five-fingered gripper. The advancements made by studying each of these platforms and sensors provide a new link between humans and robots, which in turn creates more shared understanding between the biological and digital domains. It is only through this shared understanding that we can create a future where humans and robotic systems work together with efficiency and security.","url":"https://doi.org/10.25560/88276","authors":["Freer, Daniel"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.25560/88276","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.25560/82260","name":"Flexible instruments for a snake-like robot","source":"datacite","abstract":"Minimally Invasive Surgery (MIS) is a widely adopted technique due to the many advantages it holds for patients, e.g., reductions in healing times. In MIS one procedure within many is using a snakelike robot for scarless endoscopic surgery, such as gastrointestinal endoscopic surgery. In this type of surgery, the snake-like robot is inserted through a natural orifice and is directed towards a chosen surgical site. Once the robot is in place, small robotic instrument arms are deployed from the head of the robot to perform surgical tasks, e.g., cutting or suturing. These instruments need to have a small diameter of approximately ⌀3-4mm such that they can be inserted through working channels or biopsy ports within the snake-like robot. Multiple designs of surgical instruments have been proposed in research, such as concentric tube robots, soft robots or rigid-links tendonactuated robots. On the instrument tips grippers to hold the tissue, small scissors, or knives can be mounted. Other more special types of instruments are available as well. Surgeons can control the instruments remotely and see them through a camera which is mounted on the tip of the robot. This thesis is part of the the i2Snake project which developed a homonymous snake-like robot with a length of 36.6cm and a diameter of 16mm. The length can be adapted by adjusting the length of the passive part to adapt to different procedures. In the scope of this thesis robotic instrument arms for the i2Snake robot were developed. Prototypes of these arms were built with a diameter of ⌀4mm and ⌀3mm. Similar instruments with a diameter of ⌀5mm and above were published before. For the new prototypes a rolling gear joint was developed to improve the accuracy of the arm and a gripper with an embedded distal roll. A shape sensor prototype was developed which only needs 3 receiving fibers. The 3mm instrument was optimised with a newly developed optimisation algorithm. To combine the developed approaches, a control was implemented which incorporates a reinforcement learning inverse kinematics and a mathematical model to compensate for backlash and joint coupling. The 4mm instrument with 7 DOF can bend up to 72° in each joint and has a rolling motion of 165.65°. The final 3mm instrument has 5 DOF, including a prismatic joint, and can bend up to 82° in each joint and roll 5for 90°. The learned inverse kinematics is more precise in position and orientation error than the common Damped least-squares Jacobian pseudo-inverse, mainly because it has no problems with joint limits or complex situations. Using the proposed compensation methods, the backlash was significantly reduced so that the overall average positioning error was improved to 1.49mm.","url":"https://doi.org/10.25560/82260","authors":["Schmitz, Andreas"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.25560/82260","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.17632/gstmy5tzdv.1","name":"Target Object Pose Estimation Algorithm for Eye-in-Hand Binocular Vision Systems","source":"datacite","abstract":"This work presents an eye-in-hand binocular vision calibration algorithm.

As part of a larger project to 3D print tunable antennas, it was tasked to develop a printer that could directly produce 3D stretchable electronics with soft and hard components. First, an extruder system which can directly print from raw pellets was developed to widen the input material choice as well as to lower the raw material cost. The new feeding system, fused pellets printing (FPP), permits printing of almost any thermoplastic materials by converting a screw extruder into a direct source for feed material of fused deposition modeling (FDM) style 3D printers. This innovation decouples the high-quality filament or large mass extruder from an FDM print head that can move with high speed and precision. The utility of the technique was demonstrated through direct printing of pneumatic driven soft robots which could in future be used to control antenna shapes. A tri-extruder system with three input channels was also developed to print functional devices in a single step which consists of a hard-rigid thermoplastic, a soft, stretchable elastomer, and a liquid metal. This extruder introduces mechanical interlocking in their extrudates when printing chemically immiscible polymers with nearly three orders of magnitude of difference in their elastic moduli. This intermixed printing was found to improve adhesion between adjacent printed layers by more than 12 times compared to simple side-by-side extrusion. To demonstrate the printing capability of intermixed soft and hard plastics, a tendon-driven soft robotic gripper composed of high impact polystyrene (HIPS) and styrene-ethylene-butylene-styrene (SEBS) was printed and characterized. The functionally gradient material (FGM) gripper printed with this technology did not show any noticeable interface failure after 10,000 cycles of operation whereas other samples printed without intermixing experienced layer delamination. Additionally, the extruder is also capable to co-axially extrude liquid metal alloy within an encapsulating polymer shell, in this case, SEBS. Hence, an extremely stretchable and flexible conductive wire can be produced which does not require any post-processing and an extra sealing step. 2D spiral pressure sensors and 3D inductors for sensing circumferential strain were successfully printed and characterized. An immediate drawing process was also found to be useful to produce liquid metal based micro-wires having only ~25 μm of liquid metal core with ~12 μm thick SEBS shell. These micro-wires are stretchable up to 400% without any noticeable mechanical failure and electrical loss. That opens up new possibilities to utilize the smart extruder system in neural interfaces and functional electrical stimulation (FES) therapeutical applications.","url":"https://doi.org/10.7939/r3-eczp-5021","authors":["Khondoker, Mohammad Abu Hasan"],"tags":["Adhesion Strength","Liquid Metal","Additive Manufacturing","Intermixed Extrusion","Co-axial Extrusion","3D Printing","Fused Deposition Modeling","Multi-Material Printing"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.7939/r3-eczp-5021","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.7939/83499","name":"Finding Intuitive Action Spaces for Wheelchair-Mounted Robotic Arms","source":"datacite","abstract":"Operating high degree-of-freedom robots can be difficult for users of wheelchair mounted robotic manipulators due to the common usage of Cartesian-based mode switching control. Mode switching in a Cartesian action space has several drawbacks: unintuitive control reference frames, isolated control of translation and rotation, and limited movement capabilities. Further, many state of the art methods choose Cartesian control as the basis for their system's control scheme, which may hamper performance of an otherwise sound approach. Autonomous methods aim to improve the user experience by autonomously completing tasks with minimal user input, however, some studies suggest users prefer to maintain control authority over the robot and do not like explicitly stating their task goals. To accommodate for this, shared-autonomy methods have been proposed to assist the user through learning action maps or predicting goals and providing assistance. These methods rely on learning task specific representations or require ground truth information, both of which may impede real world implementation. To remedy the issues identified in current WMRA control systems, we propose new mode switching action spaces that reallocate movement reference frames to be more intuitive and user friendly. We create a framework for mode switching that introduces wrist motions to the robot's action capabilities in addition to base-frame and end-effector aligned actions. With this framework, we create an action space representation of basis vectors to formally define different control spaces. After conducting an initial study to find optimal action reference frames for activities of daily living, we propose Point and Go mode switching, consisting of a novel translation and rotation mode with additional quality of life improvements to reduce the user's mental load. Its sweeping actions serve to provide human-like capabilities and allow us to point the gripper, which defines the new translation axis along the robot base frame's horizontal plane. This creates an intuitive `point and go' translation mode that allows the user to position and orient the end-effector without switching modes while also providing action capabilities that more closely align with human arms. The system's rotation mode combines position control with a refined end-effector oriented frame that provides precise and consistent robot actions in various end-effector poses. We verified our method's effectiveness through initial experiments that evaluated the contribution of each feature in isolation. It was then followed by a three-task user study that compared Point and Go to Cartesian mode switching and learned State Conditioned Linear Maps. Results show that compared to Cartesian-base control, our method reduced completion times by 31 %, workload by 12 %, pauses by 41 %, and mode switches by 33 %, while receiving significantly favorable responses in user surveys and significantly better control smoothness. Additionally, we matched the performance of State Conditioned Linear Maps on easy tasks, and exceeded it in more complex tasks.

Our team received the Dobot Magician robotic arm, which was named TALOS, from our academic advisor. TALOS’ goal was to be able to remove a block from a Jenga tower and subsequently place it at the top. According to Dobot’s marketing materials, this robotic arm was easy to use and hardly required any programming. Furthermore, they claimed that their robotic arms were ready to use right out of the box, leading my team to believe that we would have plenty of time during our fifteen-week semester to develop the fun aspect of playing Jenga via computer vision and other robotic-related topics. However, rather than spending the majority of our attention on these aspects, we concentrated on them for around half the time available. This was due to unexpected complications, such as being unable to install Dobot’s official SDKs on our Linux OS, which forced us to reverse-engineer the proprietary SDKs. Then we had to create custom software from scratch only to get the arm to respond to a command. Finally, we had to buy a motorized turntable to have extra access angles to the blocks on the tower’s side since, while TALOS has four degrees of freedom, the arm’s positioning capability was limited, preventing us from reaching any of them. After completing the construction of TALOS’ software and hardware capabilities, it successfully put a first block approximately 73% of the time; however, this declined when placing a second block, resulting in a 16.7% success rate. The reasons for this substantial drop in performance were mostly due to calibration issues with the robot’s y-axis positioning capability as well as a gripper lacking sufficient lateral force to grasp and move the blocks. These limitations were absent in the Dobot’s marketing materials. The primary objective of my STS Research paper is to identify and investigate how the marketing language surrounding desktop collaborative robots (cobots), specifically the Dobot Magician, produces a perceived sense of accessibility by neglecting or failing to provide the tools to complete practical application. To investigate this, I applied Hart and Cap’s Critical Discourse Analysis framework to four different types of data: promotional/technical documentation provided by Dobot, comments and posts from online discussion forums commenting on their experiences with cobots, semi-structured interviews with members of UVA’s MARS robotics team, and the TALOS technical report. A general trend emerged in three areas: democratization, safety, and ease of use. Under “HIGH QUALIFICATION STANDARDS,” Dobot claims to have certification for CE, RoHS, and FCC. These certifications confirm that the equipment meets electromagnetic compatibility requirements and environmental compliances, but they do not address whether the device can be operated safely near an individual. Furthermore, the Dobot’s user manual explicitly warns that children should not use the device independently and that adult supervision is required at all times, yet this disclaimer does not appear in any marketing material. Dobot also refers to the Magician as a “cobot” despite the fact that it does not list the ISO/TS 15066, a standard that defines collaborative robots classification. The abundance of forum postings, workaround solutions provided by teams at both the University of Arts London and Carnegie Mellon University, and comments from interview participants from the MARS team all demonstrate that the amount of unspoken labor created here is not an anomaly. When users meet these issues, marketing has already developed a framework in which failure is blamed on the user rather than the difference between what the product claims to deliver and what it actually demands. The relationship between these two projects turned out to be larger than I had anticipated.

In this paper, we introduce ATLAS, an annotation tool tailored for long-horizon robotic action segmentation. ATLAS provides time-synchronized visualization of multi-modal robotic data, including multi-view video and proprioceptive signals, and supports annotation of action boundaries, action labels, and task outcomes. The tool natively handles widely used robotics dataset formats such as ROS bags and the Reinforcement Learning Dataset (RLDS) format, and provides direct support for specific datasets such as REASSEMBLE. ATLAS can be easily extended to new formats via a modular dataset abstraction layer. Its keyboard-centric interface minimizes annotation effort and improves efficiency. In experiments on a contact-rich assembly task, ATLAS reduced the average per-action annotation time by at least 6% compared to ELAN, while the inclusion of time-series data improved temporal alignment with expert annotations by more than 2.8% and decreased boundary error fivefold compared to vision-only annotation tools.","url":"https://doi.org/10.48550/arxiv.2604.26637","authors":["Stanovcic, Sergej","Sliwowski, Daniel","Lee, Dongheui"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2604.26637","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.11575/prism/48873","name":"Embedded 3D Printing of Strain Sensors for Adaptive Soft Robotic Grippers","source":"datacite","abstract":"While soft grippers are easy to fabricate due to their simplicity, integrating sensors into them adds a layer of complexity to the manufacturing process. The widely used material for building soft robotic grippers is Ecoflex™ 00-30 (Smooth-On, Inc., USA), which is a commercially available platinum-catalyzed silicone elastomer known for its high elasticity, low modulus, and biocompatibility. If a method can be developed to embed sensors within the Ecoflex™™ matrix, it could revolutionize the field of robotics, opening new possibilities of fabricating soft robotic grippers quicker and more efficiently. This thesis introduces a method for printing sensors directly inside Ecoflex™, significantly simplifying the process of fabricating soft grippers with embedded sensors. By reducing the number of fabrication steps, this approach decreases production time and cuts the need for creating a separate mold for the conductive electrodes. In this method, a conductive pattern is directly 3D printed onto the Ecoflex™ substrate using a technique known as direct ink writing (DIW). The conductive ink used in this process was developed to ensure proper network formation of multi-walled carbon nanotubes (MWCNTs) within the PDMS (Polydimethylsiloxane, Sylgard™ 184, Dow Inc., USA) matrix. A synthesis protocol was followed to achieve this, resulting in inks with mechanical and electrical properties that favor strain sensing. Several conductive inks were formulated with 4, 6, and 8 wt.% of MWCNTs in PDMS. These formulations were rigorously tested to evaluate their performance. And the 6 wt% ink was found to have a low Young's modulus of 0.5388 ± 0.0009 MPa and low resistance of 1.962 ± 0.019 kΩ, making it ideal for strain sensing. The rheological properties of the ink were analyzed to ensure smooth and precise printing of conductive electrodes within an Ecoflex™ bath. The 6 wt.% ink showed shear-thinning behavior, with viscosity decreasing from 10.5 million to ~2,200 mPa·s between 0.01 and 100 s⁻¹ shear rates, which indicates the smooth extrudability of the ink. The flow initiation point was 196.8 Pa, which is low enough to enable ink deposition at lower dispensing pressures but high enough to ensure structural retention post-extrusion. The ink also showed gel-like behavior (G′ &gt; G″), confirming the printed shape retention property and providing support to the embedded 3D structures. Using this ink, the printing parameters such as dispensing pressure and printing speed that enabled printing fine lines using a 21G (514 µm ID) nozzle were found to be 55 kPa and 50 mm/min, respectively. Strain sensors with both straight and serpentine designs were printed, and their electrical performance was studied. In addition to sensor fabrication, a feedback loop that integrates the pneumatic dispenser and the sensor was developed to confirm the functionality of the printed sensor. The feedback loop was designed to shut the compressed air dispenser off when the gripper has gripped the object perfectly. The embedded printed sensor was found to be functional and was calibrated to hold objects successfully.","url":"https://doi.org/10.11575/prism/48873","authors":["Rejimone, Justin"],"tags":["Soft robotics","3D Prinitng","Embedded 3D Printing","Conductive inks","Education--Technology"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2027","doi":"10.11575/prism/48873","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.17605/osf.io/3548d","name":"Pear-3D-Robotics-Validation-Protocol (P3D-RVP): A Multi-Tier Technical Framework for Sensor Calibration, Workspace Benchmarking, and Field-Trial Validation in High-Density Pear Canopies","source":"datacite","abstract":"This project documents the Pear-3D-Robotics-Validation-Protocol (P3D-RVP), a multi-tier technical engineering protocol for validating 3D canopy-robotic harvesting systems in high-density pear orchards (&gt;2000 trees/ha).

However, minimal sensor sets and phase-dependent sensing strategies for accurate pick and slip detection remain largely unexplored. In this work, we design and evaluate a multimodal sensing suite integrated into a compliant suction-based apple gripper.

The contributions of this paper are a phase-dependent evaluation of multimodal sensors and the identification of minimal sensor sets for reliable pick state classification.

The PhD study aims for multimodal human-robot collaboration in assembly. For this purpose, various modalities controlled by high-level human commands are adopted to facilitate multimodal robot control in assembly and to support efficient HRC. Voice commands, as a commonly used communication channel, are firstly considered and adopted to control robots. Also, hand gestures work as nonverbal commands that often accompany voice instructions, and are used for robot control, specifically for gripper control in robotic assembly. Algorithms are developed to train and identify the commands so that the voice and hand gesture instructions are associated with valid robot control commands at the controller level. A sensorless haptics modality is developed to allow human operators to haptically control robots without using any external sensors. Within such context, an accurate dynamic model of the robot (within both the pre-sliding and sliding regimes) and an adaptive admittance observer are combined for reliable haptic robot control. In parallel, brainwaves work as an emerging communication modality and are used for adaptive robot control during seamless assembly, especially in noisy environments with unreliable voice recognition or when an operator is occupied with other tasks and unable to make gestures. Deep learning is explored to develop a robust brainwave classification system for high-accuracy robot control, and the brainwaves act as macro commands to trigger pre-defined function blocks that in turn provide micro control for robots in collaborative assembly. Brainwaves offer multimodal support to HRC assembly, as an alternative to haptics, auditory and gesture commands. Next, a multimodal data-driven control approach to HRC assembly assisted by event-driven function blocks is explored to facilitate collaborative assembly and adaptive robot control. The proposed approaches and system design are analysed and validated through experiments of a partial car engine assembly.

Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN). It is difficult to visually identify the presence of SCN in the field, let alone its population densities or numbers, as there are no obvious aboveground disease symptoms. The only definitive way to assess SCN population densities is to directly extract the SCN cysts from soil and then extract the eggs from cysts and count them. Extraction is typically conducted in commercial soil analysis laboratories and university plant diagnostic clinics and involves repeated steps of sieving, washing, collecting, grinding, and cleaning. Here we present a robotic instrument to reproduce and automate the functions of the conventional methods to extract nematode cysts from soil and subsequently extract eggs from the recovered nematode cysts. We incorporated mechanisms to actuate the stage system, manipulate positions of individual sieves using the gripper, recover cysts and cyst-sized objects from soil suspended in water, and grind the cysts to release their eggs. All system functions are controlled and operated by a touchscreen interface software. The performance of the robotic instrument is evaluated using soil samples infested with SCN from two farms at different locations and results were comparable to the conventional technique.

Robotic automation accelerates sorting through automated contaminant removal. Nevertheless, the diverse and unpredictable nature of contaminants introduces major challenges for reliable robotic grasping. Grasp performance benchmarking provides a rigorous methodology for evaluating these challenges in underexplored field contexts like food waste sorting. However, existing approaches suffer from limited simulation datasets, over-reliance on simplistic metrics like success rate, inability to account for object-related pre-grasp conditions, and lack of comprehensive failure analysis.

The benchmark compares industrial grasping across three gripper modalities through 1,750 grasp attempts across four randomized clutter levels. Results reveal a clear hierarchy among graspability parameters, with object quality emerging as the dominant factor governing grasp performance across modalities. Failure mode analysis shows that physical interaction constraints, rather than perception or control limitations, constitute the primary source of grasp failures in cluttered environments. By enabling identification of dominant factors influencing grasp performance, GRAB provides a principled foundation for designing robust, adaptive grasping systems for complex, cluttered food waste sorting.","url":"https://doi.org/10.48550/arxiv.2602.18835","authors":["Thilakarathna, Moniesha","Wang, Xing","Wang, Min","Hinwood, David","Liu, Shuangzhe","Herath, Damith"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences","B.0; B.8.0; B.8.1; B.8.2"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2602.18835","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.48550/arxiv.2512.04884","name":"Hoi! - A Multimodal Dataset for Force-Grounded, Cross-View Articulated Manipulation","source":"datacite","abstract":"We present a dataset for force-grounded, cross-view articulated manipulation that couples what is seen with what is done and what is felt during real human interaction.

To address this challenge and facilitate skill transfer from human to robot, we introduce Traj2Action, a novel framework that bridges this embodiment gap by using the 3D trajectory of the operational endpoint as a unified intermediate representation, and then transfers the manipulation knowledge embedded in this trajectory to the robot's actions. Our policy first learns to generate a coarse trajectory, which forms a high-level motion plan by leveraging both human and robot data. This plan then conditions the synthesis of precise, robot-specific actions (e.g., orientation and gripper state) within a co-denoising framework.

Inspired by agentic loops in digital tool-using agents, we reformulate language-guided grasping as a bounded embodied agent operating over grounded execution states, where physical actions expose an explicit tool-state stream. We introduce a physical agentic loop that wraps an unmodified learned manipulation primitive (grasp-and-lift) with (i) an event-based interface and (ii) an execution monitoring layer, Watchdog, which converts noisy gripper telemetry into discrete outcome labels using contact-aware fusion and temporal stabilization. These outcome events, optionally combined with post-grasp semantic verification, are consumed by a deterministic bounded policy that finalizes, retries, or escalates to the user for clarification, guaranteeing finite termination.

The rollers are mounted on a pivoting mechanism, allowing reorientation of the constraint frame to accommodate different manipulation tasks. We develop a constraint-based model of the fingertip integrated into a parallel-jaw gripper and analyze its ability to support diverse manipulation strategies. Experiments show that the proposed design enables a wide range of dexterous actions that are conventionally challenging for robotic grippers, including sliding and pivoting within the grasp, robust adaptation to uncertain contacts, multi-object or multi-part manipulation, and interactions requiring asymmetric friction across fingers.

We propose a different philosophy: detect the failure during execution and apply a small corrective \"nudge\" that salvages the attempt without replanning. Our system layers a lightweight tactile-conditioned residual policy on top of a frozen VLA base policy. A GelSight-style tactile sensor mounted on the gripper fingers detects slip onset, contact asymmetry, and insufficient grasp force within 40 ms. These tactile features condition a residual action network that outputs a corrective ΔSE(3) displacement and gripper-width adjustment, which is added to the base policy's next commanded action. The residual policy is trained from 600 demonstrations (half successes, half near-failures) using a contrastive objective that separates correctable failures from irrecoverable ones. On a physical Franka Emika Panda across 12 household objects, our system converts 74% of would-be failures into successes, raising the overall grasp success rate from 81% (VLA alone) to 95%, with only 52 ms added latency per control step.

Traditional control approaches, whether fixed-parameter methods or static evolutionary algorithms, lack the adaptability required for real-time decision-making in Industry 4.0 environments where throughput, energy efficiency, precision, equipment longevity, and safety must be simultaneously optimized. This study presents a novel adaptive multi-objective reinforcement learning framework designed for intelligent robotic manufacturing systems, with experimental validation through automated pick-and-place operations as a representative industrial use case. The proposed approach integrates dynamic preference weighting mechanisms with Pareto-optimal policy discovery, enabling real-time adaptation to changing production priorities without manual reconfiguration. Validated in high-fidelity CoppeliaSim environments with a UR5 manipulator, the framework demonstrates significant performance improvements (+24.59% to +34.75% over baseline methods, p &lt; 0.001) and achieves 95% optimal performance within 180 training episodes—representing a 5× faster convergence compared to evolutionary baselines. Critically, the framework demonstrates seamless integration capabilities with Manufacturing Execution Systems (MES), digital twins, and continual learning architectures, while maintaining edge computing compatibility (&lt;2 GB RAM, &lt;50 ms latency).

Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN). It is difficult to visually identify the presence of SCN in the field, let alone its population densities or numbers, as there are no obvious aboveground disease symptoms. The only definitive way to assess SCN population densities is to directly extract the SCN cysts from soil and then extract the eggs from cysts and count them. Extraction is typically conducted in commercial soil analysis laboratories and university plant diagnostic clinics and involves repeated steps of sieving, washing, collecting, grinding, and cleaning. Here we present a robotic instrument to reproduce and automate the functions of the conventional methods to extract nematode cysts from soil and subsequently extract eggs from the recovered nematode cysts. We incorporated mechanisms to actuate the stage system, manipulate positions of individual sieves using the gripper, recover cysts and cyst-sized objects from soil suspended in water, and grind the cysts to release their eggs. All system functions are controlled and operated by a touchscreen interface software. The performance of the robotic instrument is evaluated using soil samples infested with SCN from two farms at different locations and results were comparable to the conventional technique. Our new technology brings the benefits of automation to SCN soil diagnostics, a step towards long-term integrated pest management of this serious soybean pest.","url":"https://doi.org/10.6084/m9.figshare.20217041","authors":["Legner, Christopher","L.

Our method addresses the challenge of controlling a 13-dimensional action space involving coordinated base motion, arm articulation, and gripper actuation. To enrich spatial understanding, the model incorporates multi-view RGB observations, depth cues, and short temporal history, providing perspectives of both global scene structure and local manipulation context. To improve representation quality, we co-train auxiliary decoders that reconstruct interpretable intermediate signals - including global robot position, joint configurations, grasp affordances, target-object relative pose, and segmentation masks - from shared visual-language features. These objectives provide dense supervision that encourages the backbone to develop spatially grounded, manipulation-aware latent representations. Through extensive evaluation on home rearrangement tasks, our approach achieves consistent improvements across picking, placing, opening, and closing operations, substantially outperforming direct imitation learning.

The internal structure of the programmable materials enables reversible material properties, behavior, or shape changes according to a program. As the programmable materials require neither control electronics nor technical devices or cables, the self-sufficient behavior makes them fulfill sensor and actuator functionality. Shape memory polymers (SMPs) are smart materials that qualify as functional base materials to design programmable materials. SMPs can retain an imposed, temporary shape after thermomechanical treatment, also called programming. The initial, permanent shape can be recovered when applying an external stimulus like heat. In the last decade, thermoplastic polyurethanes (TPUs) belonged to the most researched SMPs. The thermoplastic nature of TPUs permits them to be molded using classical melt-based processing techniques like extrusion, injection molding, etc. Additive manufacturing (AM), alias three-dimensional (3D) printing, is an effective layer-by-layer technique to process thermoplastic polymers into 3D objects. Amidst various AM technologies, fused filament fabrication (FFF) is a hot-melt extrusion-based 3D printing process and is widely prevalent. The doctoral thesis aims to utilize self-synthesized and commercially available TPUs for FFF and to specifically influence the printing technology to produce either non-thermoresponsive or thermoresponsive objects or structures and open up new material and system functionalities. The primary hurdle of this doctoral study was to process SMPs using a standard commercially available FFF machine. Motivated by the fact that previously presented manufacturing processes of thermoresponsive quick response (QR) codes were too time-consuming for production, QR codes were initially developed as anti-counterfeiting technology. The work introduces a novel manufacturing method for the same, thereby also addressing the AM of TPU-based SMP using standard FFF machines. Following this, the layer deposition pattern of tensile bars of TPU with shape memory properties was modified to achieve printing either in vertical or horizontal orientation. After processing commercially available polyester urethane and characterization, the mechanical and shape memory properties of the 3D printed samples were studied, and the results were compared to its injection-molded analogs and other materials manufactured via FFF. The results showed that the direction of loading and printing pattern orientation could be utilized to control the shape recovery stress and mechanical properties. Subsequently, the filigree printing and the smallest structure that can be obtained from FFF were explored by printing Arial fonts of the letter “A” in different sizes. Afterward, the potential application of SMP as thermally activatable and de-activatable gears and innovative smart keyboard keys was developed by utilizing the one-way (1W) shape memory effect (SME). The second part of the work concentrates on four-dimensional (4D) printing employing FFF that enables the production of thermoresponsive objects directly in AM process. The work presents a facile FFF printing strategy for commercially available polylactic acid (PLA) material and an in-house synthesized thermoplastic polyether urethane to obtain highly shrinkable objects, which allowed to show how to achieve precise control over the shapes after printing and heating.

A survey undertaken by the author however, revealed that due to the high cost of existing fully automated systems, Australian manufacturers producing low to medium transformer volumes continue to maintain a manual construction approach. The conceptual design of a cost-effective automation system for core assembly from pre-cut lamination stacks was consequently undertaken. The major hurdle for automating the existing manual process was identified as the difficulty in reliably handling and accurately positioning the constituent core laminations, which number in their thousands, during transformer core construction. Technical evaluation of the proposed pick-and-place core assembly system, incorporating two mobile robots bearing a common gripper, is presented herein to address these requirements. A unique robotic gripper, having the capability to selectively pick a given number of steel laminations (typically two or three) concurrently from a stack, has the potential to significantly increase productivity. The only available avenue for picking multiple laminations was deemed to be a gripper based on magnetism. Closed form analytical and finite element models for an electromagnet-stack system were contrived and their force distributions obtained. The theoretical findings were validated by experiment using a specially constructed prototype. Critical parameters for reliably lifting the required number of laminations were identified and a full scale electromagnet, that overcame inherent suction forces present in the stack during picking, was subsequently developed. A mechanical docking arrangement is envisaged that will ensure precise lamination placement. Owing to the grippers unwieldy length however, conventional robots cannot be used for assembling larger cores. Two wheeled mobile robots (WMRs) compliantly coupled to either end of the gripper could be considered although a review of the current literature revealed the absence of a suitable controller. Dynamic modelling for a single WMR was therefore undertaken and later expanded upon for the dual WMR system conceived. Nonlinear adaptive controllers for both WMR systems were developed and subsequently investigated via simulation. Neglecting the systems dynamics resulted in analogous, simplified kinematic control schemes, that were verified experimentally using prototypes. Additional cooperative control laws ensuring the synchronisation of the two robots were also implemented on the prototype system.","url":"https://doi.org/10.25439/rmt.27580941","authors":["Postma, Bradley"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.25439/rmt.27580941","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.5281/zenodo.19090128","name":"Comparative Analysis of Grasp Quality  Classification Approaches for Robotic  Manipulation Using ROS2","source":"datacite","abstract":"Reliable grasp quality estimation is fundamental to robotic manipulation but remains challenging without expensive tactile or force-torque sensors.

These constraints present major obstacles to achieving safe and effective force control in demanding applications such as Minimally Invasive Surgery (MIS) and space exploration, where direct force measurement is often impractical. To address these challenges, this work considers a CM based gripper system as a testing apparatus for providing real-time, force feedback via structural deformation as a visual cue, thereby communicating force information without embedded sensors. Thus, this research characterizes the CM-based force feedback capabilities and subsequently develops a Machine Learning (ML) model to predict gripping force information, an important factor to advance the CM-gripper towards a future computer-assisted force feedback system.The study adopted a two-phase approach to bridge mechanical characterization with intelligent force prediction of a compliant mechanism (CM) gripper. In the first phase (Paper 1), the force-deflection properties of a CM gripper are experimentally characterized, revealing non-linear relationships between structural deformation and pinch forces. The nonlinearity is attributed to plastic deformation that was observed in the experiments due to excessive actuation. This finding redefined the experimental conditions to remain within the elastic region. In a separate work, the experiments were repeated under these requirements and showed linear agreement, which enables a linear based visual force feedback system.These findings directly inform the second phase (Paper 2), where the established relationships guide the selection and training of machine learning models. The experimental data from Paper 1 served as the foundation for understanding the design parameters for ML model development. In the work presented in Paper 2, ML models were systematically developed and verified against experimental data for pinch force prediction. The ML based research also employed a multi-metric evaluation framework - combining performance, absolute error and execution time visualized via radar charts to address critical gaps left by prior studies that rely on single performance indicators. Out of the seven ML models tested, the Weighted Regression demonstrated the best overall performance (Radar Chart Area = 0.95: R 2 = 96.27%, Mean Absolute Error = 0.51N, Execution Time = 1.41 s).This research developed a deformation-based ML-driven model to translate visual cues from a compliant mechanism gripper to pinch force prediction. This work forms a critical component of a larger research initiative aiming to integrate the ML model with image processing software to create a CM-gripper system equipped with real time computer-assisted force feedback capabilities. Such advances pave the way for future evaluations of two distinct force feedback systems using the CM based gripper system as a testing apparatus, specifically (a) human-assisted gripper manipulation, where force predictions are graphically overlaid to guide users and (b) fully automated ML-controlled gripper system that autonomously adjusts and maintains the required pinch force without user intervention. Collectively, this research moves this field closer to an intelligent, sensor-less robotic manipulation system.","url":"https://doi.org/10.25394/pgs.29695529.v1","authors":["Mohanty, Vineet"],"tags":["Solid mechanics","Mechanical engineering not elsewhere classified","Machine learning not elsewhere classified"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.25394/pgs.29695529.v1","addedAt":"2026-08-31T06:34:16.416Z","updatedAt":"2026-08-31T06:34:16.416Z"},{"id":"doi:10.7746/jkros.2026.21.1.122","name":"Pneumatic Pouch Actuator-Driven Origami Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.7746/jkros.2026.21.1.122","authors":["Sujong An","Hyunhwan Jeong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-20T00:14:59Z","doi":"10.7746/jkros.2026.21.1.122","addedAt":"2026-08-31T06:34:16.555Z","updatedAt":"2026-08-31T06:34:16.555Z"},{"id":"doi:10.2139/ssrn.5908063","name":"Faith as a Sensor Rather than an Actuator","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5908063","authors":["Marius Costandin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-01-08T18:40:47Z","doi":"10.2139/ssrn.5908063","addedAt":"2026-08-31T06:34:16.555Z","updatedAt":"2026-08-31T06:34:16.555Z"},{"id":"doi:10.1002/adrr.202500173","name":"A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine","source":"crossref","abstract":"This work presents a soft robotic fish that achieves large‐amplitude tail fin bending through a novel design where dielectric elastomer actuators (DEAs) are functionally integrated to form the body.

It should weigh as little as possible without compromising functionality or its performance. This study aims to reconsider the construction of a lightweight robotic gripper by modifying the gripper's materials and topology. Using the finite element (FE) method, several types of gripper materials were evaluated for static stress. On the basis of the results of the FE analysis, the optimal material candidate was chosen using the weighted objective method. Using the Fusion 360 software, the topology of the selected material was then optimized in an effort to achieve the 40% weight reduction’s objective. In addition, the suggested optimized geometry is then fine-tuned so that it can be manufactured as efficiently as possible. The final step in the validation of the robotic gripper's design was stress static analysis. The revised gripper design has a mass of 0.08 kg, a reduction of 94% from the original mass, and a safety factor of 3.67%, which satisfies the desired level of performance for the robotic gripper. Utilizing different materials and optimizing the gripper's topology can significantly reduce the overall mass of a robotic gripper.&#x0D;","url":"https://doi.org/10.37231/myjas.2023.8.1.344","authors":["Mohd Nizam Sudin","N.

Robotic cells with a single‐gripper robot have been extensively studied in the literature. By contrast, cells with a dual‐gripper robot, although more productive, have received less attention, perhaps because of their inherent complexity. We consider the problem of scheduling operations in dual‐gripper robotic cells that have the machines configured in a circular layout and that produce identical parts repetitively. A typical objective in practice is to find a 1‐unit cyclic sequence of robot moves that maximizes the throughput. We show that dual‐gripper cycles are not optimal in all cases. We establish conditions in which the problem of finding an optimal 1‐unit cycle in dual‐gripper cells is NP‐hard. We show that the remaining cases are solvable by polynomial‐time algorithms either optimally or within a guaranteed bound of the optimum. These results are extended to linear cells. A computational study demonstrates that the algorithm performs much better on average than this worst‐case bound suggests. Our theoretical studies facilitate research into the complexity status of the corresponding domain. They also provide practical insights that are useful in maximizing productivity for any combination of cell parameters and either type of robot.","url":"https://doi.org/10.1111/poms.12797","authors":["Kyung Sung Jung","H.

In this paper, we consider scheduling of operations in a bufferless dual-gripper robotic cell processing multiple part types. The processing constraints specify the cell to be a flowshop. The objective is to determine the robot move sequence and the sequence in which parts are to be processed so as to maximize the long-run average throughput rate for repetitive production of parts. We provide a framework to study the problem, and address the issues of problem complexity and solvability. Focusing on a particular class of robot move sequences, we identify all potentially optimal robot move sequences for the part-sequencing problem in a two-machine dual-gripper robot cell. In the case when the gripper switching time is sufficiently small, we specify the best robot move sequence in the class. We prove the problem of finding an optimal part sequence to be strongly NP-hard, even when the robot move sequence is specified. We provide a heuristic approach to solve the general two-machine problem and evaluate its performance on the set of randomly generated problem instances. We perform computations to estimate the productivity gain of using a dual-gripper robot in place of a single-gripper robot. Finally, we extend our results for the two-machine cell to solve an m-machine problem.","url":"https://doi.org/10.1287/opre.1030.0073","authors":["Chelliah Sriskandarajah","Inna Drobouchevitch","Suresh P.

In contrast, fabric‐based inflatable structures offer high stiffness‐to‐weight ratio solutions for soft robotics, but their actuation has been little explored. Herein, a new class of pneumatic soft grippers is presented that exploits the in‐plane overcurvature effect of inextensible fabric flat balloons upon inflation. A star‐shaped gripper contracts radially under pressure producing a gripping force on the object whose intensity can be modulated by the pressure input. First, the kinematics and mechanics of a single V‐shaped actuator are studied through experiments, finite element simulations, and analytical models. Then, these results are leveraged to predict the mechanical response of the entire star, optimize its geometry, and maximize contraction and stiffness. It is shown that the gripping performance can be improved by stacking several stars with silicon‐coated corners. It is expected that the flexibility, robustness, scalability, and ease of fabrication of this methodology will lead to a new generation of lighter and larger actuators capable of developing higher forces and moving delicate and irregularly shaped objects while maintaining reasonable complexity.","url":"https://doi.org/10.1002/aisy.202200435","authors":["Ignacio Andrade-Silva","Joel Marthelot"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-04-28T08:06:43Z","doi":"10.1002/aisy.202200435","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.3389/frobt.2017.00046","name":"A Modular, Reconfigurable Mold for a Soft Robotic Gripper Design Activity","source":"crossref","abstract":"","url":"https://doi.org/10.3389/frobt.2017.00046","authors":["Jiawei Zhang","Andrew Jackson","Nathan Mentzer","Rebecca Kramer"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-09-26T00:27:23Z","doi":"10.3389/frobt.2017.00046","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1016/j.mechmachtheory.2017.10.027","name":"A robotic gripper for picking up two objects simultaneously","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.mechmachtheory.2017.10.027","authors":["Taylan Atakuru","Evren Samur"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-12-06T07:06:12Z","doi":"10.1016/j.mechmachtheory.2017.10.027","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1109/robio55434.2022.10011873","name":"Visuotactile Feedback Parallel Gripper for Robotic Adaptive Grasping","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio55434.2022.10011873","authors":["Boyue Zhang","Shaowei Cui","Chaofan Zhang","Jingyi Hu","Shuo Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-01-18T18:51:38Z","doi":"10.1109/robio55434.2022.10011873","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1063/5.0192110","name":"Design and optimization of soft gripper for material handling using a robotic arm","source":"crossref","abstract":"","url":"https://doi.org/10.1063/5.0192110","authors":["Bassam Mohammed Hamood Ahmed AL-Awadhi","Nitin Chauhan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-01-30T13:56:27Z","doi":"10.1063/5.0192110","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1504/ijmms.2016.075402","name":"Micro manipulation by a compliant piezoelectric micro gripper towards robotic micro assembly","source":"crossref","abstract":"","url":"https://doi.org/10.1504/ijmms.2016.075402","authors":["Ravi Kant Jain","Somajyoti Majumder","Bhaskar Ghosh","Surajit Saha"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-03-20T12:30:06Z","doi":"10.1504/ijmms.2016.075402","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1007/s10846-019-01077-z","name":"Retraction Note to: Input Displacement Neuro-fuzzy Control and Object Recognition by Compliant Multi-fingered Passively Adaptive Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s10846-019-01077-z","authors":["Dalibor Petković","Shahaboddin Shamshirband","Nor Badrul Anuar","Aznul Qalid Md Sabri","Zulkanain Bin Abdul Rahman","Nenad D.

A visual–tactile recognition method is proposed to overcome the disadvantages of both methods in this article. The design and fabrication of the soft gripper considering the visual and tactile sensors are implemented, where the Kinect v2 is adopted for visual information, bending and pressure sensors are embedded to the soft fingers for tactile information.

However, it is still concentrated in certain industries (i.e., electronics and automotive) where standardization of product physical form is high. Current state‐of‐the‐art gripping solutions fall short when they need to accommodate items with high variability in physical form. This challenging scenario for automation can be found in a few industries (i.e., e‐commerce). Automation of pick‐and‐place processes in this area requires a more versatile gripping solution. To resolve this challenge, this article proposes a novel way to improve grip‐versatility by synergizing the mechanical and machine intelligence of a hybrid robotic gripper (HRG). Comparative analysis with commercial grippers shows that HRG can pick a more diverse range of items with success rate 94.78%. Visual perception‐based picking strategy is developed to automate the reconfiguration of HRG into a stable grasp pose for different objects. Using the proposed reconfigurable picking strategy, the efficacy of HRG in pick‐and‐place tasks is evaluated using three parameters—mean pick per hour (MPPH), successful execution over total attempts (SETA), and average cycle time (AVGCT). HRG can effectively pick items in cluttered workspace with MPPH of 98.54 ± 15.49, SETA of 0.93 ± 0.11, and AVGCT of 34.76 ± 3.31 s.","url":"https://doi.org/10.1002/aisy.202300533","authors":["Phone May Khin","Chen‐Hua Yeow","Marcelo H.

Dynamic and static analyses were performed to validate the structural integrity, force distribution, and load-handling capacity of the gripper. The mechanical design incorporated lightweight honeycomb structures to maximize the strength-to-weight ratio, while under actuation minimized actuator complexity. Following structural validation, a closed-loop control algorithm was implemented using Force Sensing Resistor (FSR) feedback to regulate grasping force in real time. The system estimates object weight dynamically and adjusts the force threshold iteratively to ensure stability without exceeding the structural limits or causing object damage. Experimental validation using cylindrical, spherical, and rectangular objects demonstrated that tactile sensing significantly reduced excessive gripping force and improved stability, as quantified by a force reduction metric. The gripper achieved reliable handling of objects ranging from 0.025 to 5𝑘𝑔, enhancing the UR5 robot’s dexterity and versatility for industrial applications. Results suggest that incorporating tactile feedback and adaptive force control mechanisms greatly improve the performance and safety of robotic gripping systems. Future work will explore machine learning-based adaptive control strategies to extend the gripper's capabilities to a broader range of materials and surface textures. This approach offers a cost-effective, customizable solution for enhancing autonomous robotic manipulation in dynamic, unpredictable environments.","url":"https://doi.org/10.62704/10057/31196","authors":["Yimesker Yihun","Yi Sheng Tan","Safeh Clifton Mawah","Amanuel Tereda","Hongsheng He"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-30T18:35:54Z","doi":"10.62704/10057/31196","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.38032/scse.2025.3.30","name":"Design, Development and Performance Evaluation of a Vacuum type Gripper Based Pick and Place Robotic Arm","source":"crossref","abstract":"This research paper presents the design and development of a 3 DOF Vacuum-type Gripper-based Pick and Place Robotic Arm, integrated with IoT capabilities to meet Industry 4.0 standards. The robotic arm addresses previous limitations in accuracy and precision, utilizing stepper motors instead of servo motors and operating without sensors. The arm is designed to move flat objects between locations with high precision, using a vacuum gripper and controlled by an ESP32 microcontroller. The system supports three modes: Autonomous, Web app-controlled, and Joystick-controlled. In Autonomous mode, a visual camera detection system identifies objects, and the arm automatically grasps them with its gripper. The Web app-controlled mode, hosted on an ESP32 microcontroller, allows for easy reprogramming without coding, while the Joystick mode uses a DS4 controller for manual adjustments. The robot's performance was evaluated through 50 trials at three different speeds (500mm/min, 166.67mm/min, and 100mm/min) and with various payloads (15-50g). Results showed that the robot could reliably handle objects within a 10-30g range, achieving 97% accuracy at minimum speed. Precision decreased at higher speeds but remained acceptable at moderate speeds. Overall, the use of stepper motors improved the robot’s accuracy and precision. The study concludes that the robotic arm is a viable solution for automating pick-and-place tasks, enhancing productivity, safety, and cost-efficiency in industrial settings by replacing human labor in material handling. The system's adaptability and precision make it a promising tool for future industrial automation. This kind of robot will potentially reduce reliance on human labor in the material handling area.","url":"https://doi.org/10.38032/scse.2025.3.30","authors":["Md.

To address this, we propose a novel variable stiffness gripper (VSG). The VSG design is based on a parallel-guided beam structure inserted by a slider from one end, allowing stiffness variation by changing the length of the parallel beams participating in the system. This design enables continuous adjustment between high compliance and high stiffness of the gripper fingers, providing robustness through its mechanical structure. The linear analytical model of the deflection and stiffness of the parallel beam is derived, which is suitable for small and medium deflections. The contribution of each parameter of the parallel beam to the stiffness is analyzed and discussed. Also, a prototype of the VSG is developed, achieving a stiffness ratio of 70.9, which is highly competitive. Moreover, a vision-based force sensing method utilizing ArUco markers is proposed as a replacement for traditional force sensors. By this method, the VSG is capable of closed-loop control during the grasping process, ensuring efficiency and safety under a well-defined grasping strategy framework. Experimental tests are conducted to emphasize the importance and safety of stiffness variation. In addition, it shows the high performance of the VSG in adaptive grasping for asymmetric scenarios and its ability to flexible grasping for objects with various hardness and fragility. These findings provide new insights for future developments in the field of variable stiffness grippers.","url":"https://doi.org/10.1017/s026357472300156x","authors":["Jiaming Fu","Ziqing Yu","Qianyu Guo","Lianxi Zheng","Dongming Gan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-12T02:35:56Z","doi":"10.1017/s026357472300156x","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1109/aim46323.2023.10196149","name":"STAR–2: A Soft Twisted-string-actuated Anthropomorphic Robotic Gripper: Design, Fabrication, and Preliminary Testing","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim46323.2023.10196149","authors":["Aaron Baker","Claire Foy","Steven Swanbeck","Revanth Konda","Jun Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-02T17:35:59Z","doi":"10.1109/aim46323.2023.10196149","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1002/9780470690574","name":"Veterinary Practice Management","source":"crossref","abstract":"","url":"https://doi.org/10.1002/9780470690574","authors":["John Bower","John Gripper","Peter Gripper","Dixon Gunn"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-02-25T10:23:34Z","doi":"10.1002/9780470690574","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1016/j.matpr.2020.04.017","name":"Novel design and kinematic analysis of a 5-DOFs robotic arm with three-fingered gripper for physical therapy","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.matpr.2020.04.017","authors":["Jyotindra Narayan","Shivansh Mishra","Gaurav Jaiswal","Santosha K.

At collision onset, to deal with relatively low contact forces, adopting low stiffness and damping can effectively mitigate the rebound of the dynamic targets. As the contact area and forces increase, employing high stiffness and damping becomes necessary for absorbing high energy. This paper proposed a novel robotic gripper whose stiffness and damping follow a predefined profile “low stiffness and damping for low impact and high stiffness and damping for high impact.” The variable effects of impact buffering and energy dissipation in a collision process were modeled and analyzed. Then, a passive variable stiffness and damping regulator (P-VSDR) was developed where tendons and pulleys are used to generate a nonlinear motion from a linear spring-damper unit. The contact dynamics model of the robotic gripper equipped with P-VSDR was established. Simulated and experimental results show that this gripper enables reliable capture of dynamic targets with different velocities.","url":"https://doi.org/10.1017/s0263574725102105","authors":["Shangkui Yang","Zhibin Song","David T.

Soft robotics takes inspiration from living organisms’ ability to adapt to their environment using flexible structures. These systems have to generate mechanical forces and simultaneously sense their environment. We developed a soft gripper with integrated sensing microstructures by monolithically 3D printing the structure. The rubber gripper mimics the versatile sensing and actuation abilities of living organisms. This is done using stereolithographic printing technology, rubber material, and resistive, pressure sensitive EGaIn microchannels. Printed microscale pressure sensing cavities are filled with liquid metal and act as resistive pressure sensors. They imitate human haptic perception and provide a sensitivity of 0.5% kPa −1 . Simultaneously, a soft-robotic actuator design, which is derived from pneumatic networks, delivers a force of 2.5 N with 16 kPa of actuating pressure and an average efficiency of 0.56 mW kPa −1 . Monolithically 3D printed systems promise numerous advantages since the compliance matching between multi-modal capillary sensing networks and actuators enables scale production of smart soft manipulators.

By strategically combining multiple levels of spherical joints, the palm passively conforms to the object during grasping and readily accommodates embedded orientation sensors. Using the measured joint pose angles in combination with a surface-fitting algorithm, the gripper can rapidly reconstruct the surface model of the object.

Grasping is one of the most common tasks in industry and daily life. In addition to typical pick-and-place task, grasping a tool is the basis for performing other tasks, such as grabbing the key to open the door, grabbing a hammer to nail, etc. The robotic grippers are the manipulator in which the robot completes the grasp. Their performance characteristics have a significant impact on work efficiency because they are the parts interacting with the grasping objects directly. Therefore, this paper researches on robotic gripper and its related technology from the following aspects. First of all, the current robotic gripper type is analyzed in detail. Second, the research status of the most promising robotic gripper is reviewed widely. Third, the critical technology of robotic gripper is studied deeply. Finally, the analysis of robotic gripper development trend is performed prospectively.","url":"https://doi.org/10.1088/1757-899x/782/4/042055","authors":["Zhang Long","Qian Jiang","Tao Shuai","Feijuan Wen","Chunping Liang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-04-15T03:17:45Z","doi":"10.1088/1757-899x/782/4/042055","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1080/15397734.2026.2643458","name":"Machine learning assisted mechanical design: multi objective optimization of welding parameters for robotic gripper joint","source":"crossref","abstract":"","url":"https://doi.org/10.1080/15397734.2026.2643458","authors":["K.

This study explores a Kirigami-based soft robotic gripper, designed to handle a wide range of objects with minimal risk of damage. The gripper utilizes a Kirigami-inspired structure combined with Liquid Silicone Rubber (LSR CN-251), chosen for its flexibility, durability, and food-safe properties. Finite element analysis was conducted to analyze the gripper’s mechanical performance under tensile forces ranging from 0.1 N to 4.3 N, focusing on stress distribution and deformation. Experimental validation was performed to verify the simulated results and assess the gripper’s performance in real-world scenarios. The simulations revealed predictable stress distribution and controlled deformation, with experimental tests demonstrating the gripper’s successful handling of delicate items, irregular objects, heavier item, and others. The Kirigami structure’s passive force distribution enabled a secure yet gentle grip, minimizing the risk of damage. The gripper’s adaptability, flexibility, and lightweight construction were confirmed in these tests. Manufactured from food-safe LSR, the gripper presents a cost-effective and efficient alternative to traditional pneumatic or jamming-based grippers. Limitations in the experimental setup, such as the restricted range of the uArm Swift Pro, were noted, and future research should explore dynamic performance under real-world conditions, enhance the range of motion, and integrate sensory feedback for improved precision.","url":"https://doi.org/10.5614/j.eng.technol.sci.2025.57.4.3","authors":["Efrem Olivio Gomes","Shyang-Jye Chang","Ilham Saputra"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-25T09:52:48Z","doi":"10.5614/j.eng.technol.sci.2025.57.4.3","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:35.624Z"},{"id":"doi:10.1109/icra.2014.6906621","name":"In-hand precise twisting and positioning by a novel dexterous robotic gripper for industrial high-speed assembly","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2014.6906621","authors":["Fei Chen","Ferdinando Cannella","Carlo Canali","Traveler Hauptman","Giuseppe Sofia","Darwin Caldwell"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-09-30T16:32:36Z","doi":"10.1109/icra.2014.6906621","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1016/j.mechmachtheory.2024.105779","name":"Analysis and design optimization of a compliant robotic gripper mechanism with inverted flexure joints","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.mechmachtheory.2024.105779","authors":["Pongsiri Kuresangsai","Matthew O.T.

To address this, we propose MaskNet, an instance segmentation network tailored for RGB-D input, designed to enhance recognition performance under occlusion and low-texture conditions. Built upon a Vision Transformer backbone, MaskNet adopts a dual-branch architecture for RGB and depth modalities and integrates multi-modal features using an attention-based fusion module. Further, spatial and channel attention mechanisms are employed to refine feature representation and improve instance-level discrimination. The segmentation outputs are used in conjunction with regional depth to optimize the grasping sequence. Experimental evaluations on camshaft depalletizing tasks demonstrate that MaskNet achieves a precision of 0.980, a recall of 0.971, and an F1-score of 0.975, outperforming a YOLO11-based baseline. In an actual scenario, with a self-designed flexible magnetic gripper, the system maintains a maximum grasping error of 9.85 mm and a 98% task success rate across multiple camshaft types. These results validate the effectiveness of MaskNet in enabling fine-grained perception for robotic manipulation in cluttered, real-world scenarios.","url":"https://doi.org/10.3390/act14080370","authors":["Runxi Wu","Ping Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-24T14:11:44Z","doi":"10.3390/act14080370","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:30.171Z"},{"id":"doi:10.1109/lra.2023.3330051/mm1","name":"ReC-Gripper: A Reconfigurable Combined Suction and Fingered Gripper for Various Logistics Picking and Stowing Tasks_supp1-3330051.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2023.3330051/mm1","authors":["Hyouk Ryeol Choi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-11-06T14:49:14Z","doi":"10.1109/lra.2023.3330051/mm1","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1007/978-3-030-45402-9_5","name":"Approximation of the Workspace of a Cable-Driven Parallel Robot with a Movable Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-030-45402-9_5","authors":["Larisa Rybak","Elena Gaponenko","Dmitry Malyshev"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-05-13T07:04:37Z","doi":"10.1007/978-3-030-45402-9_5","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1002/aisy.202370061","name":"Self‐Regulated Self‐Healing Robotic Gripper for Resilient and Adaptive Grasping","source":"crossref","abstract":"","url":"https://doi.org/10.1002/aisy.202370061","authors":["Huijiang Wang","Seppe Terryn","Zhanwei Wang","Guy Van Assche","Fumiya Iida","Bram Vanderborght"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-22T23:51:02Z","doi":"10.1002/aisy.202370061","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/icra48891.2023.10160893","name":"Tendon-Driven Soft Robotic Gripper with Integrated Ripeness Sensing for Blackberry Harvesting","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra48891.2023.10160893","authors":["Alex Qiu","Claire Young","Anthony L.

The main idea is to combine the under-actuated cable driven mechanism of a soft gripper finger with particle and layer jamming mechanisms to create a new grasping function with variable stiffness for different manipulation requirements. The movement of the soft gripper finger is produced by a cable-driven mechanism. However, particle and layer jamming chambers were embodied as a variable stiffness mechanism for the variable stiffness function. A single soft gripper finger module was developed and tested with particle and layer jamming chamber attached to it. The stiffness and response time of the soft gripper finger were measured in three distinct configurations: single finger module, particle jamming chamber attached to the finger, and layer jamming chamber attached to the finger. The comparison reveals that combining a soft finger with particle jamming increased performance by 20% compared to using the soft finger alone, while combining it with layer jamming led to an 80% increase. Additionally, layer jamming combined with a soft finger showed a 28% increase compared to particle jamming combined with a soft finger. Furthermore, simulation of the soft finger was conducted to estimate the deflection of the soft gripper finger under various applied forces. Moreover, proposed closed loop smart stiffness mechanism for the soft gripper was modeled and simulated by evaluating both soft and hard objects and simulation results were obtained for different cases. The findings indicated that the stiffness of the soft gripper finger can be adjusted for different grasping requirements.","url":"https://doi.org/10.1007/s41315-024-00398-z","authors":["Amr M.

A novel contigutive robotic gripper was used in the present study for direct adhesion contact to meet the technical challenges of force-closure of the grasp. The crux of the design was realized through an iterative optimization so as to ensure mismatch of natural frequency of the gripper and the forcing frequency in order to avoid resonance condition. Natural frequencies and mode shapes of the prototype gripper system were studied in order to understand its dynamic behaviour. Two commercial Finite Element Analysis Software were used for the effective characterization of the real-time dynamics of the gripper system.

Such a robotic system has a potentially large reachable workspace, large load capacity, high payload-to-weight ratio, high reconfigurability, and low inertia, relative to rigid link serial and parallel robots. In this work, a multi-degrees-of-freedom cable-suspended robot that can carry out pick-and-place tasks in large workspaces with heavy loads is designed. The proposed cable-driven parallel robot is composed of a rigid frame and an end-effector that is suspended from eight cables—four upper cables and four lower cables. The lengths of the cables are computed from the given positions of the suspended end-effector using a kinematic model. However, most multi-cable-driven robots suffer from interference among the cables, requiring a complex control methodology to find a target goal. Owing to this issue with cable-driven parallel robots, the whole control structure decomposes positioning control missions and allocates them into upper level and lower level. The upper level control is responsible for tracking the suspended end-effector to the target region. The lower level control makes fine positional modifications. Experimental results reveal that the hybrid control mode notably improves positioning performance. The wide variety of issues that are considered in this work apply to aerostats, towing cranes, locomotion interfaces, and large-scale manufacturing that require cable-driven parallel robots.","url":"https://doi.org/10.1177/1729881418803845","authors":["Jonqlan Lin","Chi Ying Wu","Julian Chang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-10-03T04:18:55Z","doi":"10.1177/1729881418803845","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1002/aisy.202170031","name":"Hybrid System Analysis and Control of a Soft Robotic Gripper with Embedded Proprioceptive Sensing for Enhanced Gripping Performance","source":"crossref","abstract":"","url":"https://doi.org/10.1002/aisy.202170031","authors":["Myungsun Park","Bomin Jeong","Yong-Lae Park"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-03-22T13:15:20Z","doi":"10.1002/aisy.202170031","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1007/s11548-024-03245-5","name":"HybGrip: a synergistic hybrid gripper for enhanced robotic surgical instrument grasping","source":"europepmc","abstract":"Abstract Purpose A fundamental task of a robotic scrub nurse is handling surgical instruments. Thus, a gripper capable of consistently grasping a wide variety of tools is essential. We introduce a novel gripper that combines granular jamming and pinching technologies to achieve a synergistic improvement in surgical instrument grasping. Methods A reliable hybrid gripper is constructed by integrating a pinching mechanism and a standard granular jamming gripper, achieving enhanced granular interlocking. For our experiments, our prototype is affixed to the end-effector of a collaborative robot. A novel grasping strategy is proposed and utilized to evaluate the robustness and performance of our prototype on 18 different surgical tools with diverse geometries. Results It is demonstrated that the integration of the pinching mechanism significantly enhances grasping performance compared with standard granular jamming grippers, with a success rate above 98%. It is shown that with the combined use of our gripper with an underlying grid, i.e., a complementary device placed beneath the instruments, robustness and performance are further enhanced. Conclusion Our prototype’s performance in surgical instrument grasping stands on par with, if not surpasses, that of comparable contemporary studies, ensuring its competitiveness. Our gripper proves to be robust, cost-effective, and simple, requiring no instrument-specific grasping strategies. Future research will focus on addressing the sterilizability of our prototype and assessing the viability of the introduced grid for intra-operative use.","url":"https://doi.org/10.1007/s11548-024-03245-5","authors":["Jorge Badilla-Solórzano","Sontje Ihler","Thomas Seel"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1007/s11548-024-03245-5","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.15282/jmmst.v4i2.5181","name":"Design of spline surface vacuum gripper for pick and place robotic arms","source":"crossref","abstract":"The gripper is the most important part in an industrial robot. It is related with the environment around the robot. Today, the industrial robot grippers have to be tuned and custom made for each application by engineers, by searching to get the desired repeatability and behaviour. Vacuum suction is one of the grippers in Watch Case Press Production (WCPP) and a mechanism to improve the efficiency of the manufacturing procedure. Pick and place are the important process for the annealing process. Thus, by implementing vacuum suction gripper, the process of pick and place can be improved. The purpose of vacuum gripper other than design vacuum suction mechanism is to compare the effectiveness of vacuum suction gripper with the conventional pick and place gripper. Vacuum suction gripper is a mechanism to transport part and which later sequencing, eliminating and reducing the activities required to complete the process. Throughout this study, the process pick and place became more effective, the impact on the production of annealing process is faster. The vacuum suction gripper can pick all part at the production which will lower the loss of the productivity. In conclusion, vacuum suction gripper reduces the cycle time about 20%.

Various, mostly complex grippers already exist based on certain actuation concepts. However, each solution has specific limitations, especially regarding gripping different soft and delicate objects. Therefore, this paper introduces a new approach to design a simple, adaptive, and versatile soft robotic two-finger gripper that is based on compliant mechanisms. More specifically, an inherently gentle touch is realized by utilizing an optimally synthesized mechanism with distributed compliance in combination with a conventional linear actuator. It is shown by finite elements method (FEM) simulations that the gripper realizes a high force and motion transmission at the same time. Furthermore, it is demonstrated by tests with a gripper prototype that reliable, safe, and fast grasping as well as manipulation are possible for a wide variety of objects. It is shown that beside regular and stiff objects also very challenging objects can be easily gripped, e.g., small, irregular, soft, and squeezable objects like fruits, berries, and vegetables. Moreover, it is confirmed that the developed compliant two-finger gripper can be used beneficially without sensors and control for differently sized and shaped objects with a comparable weight.","url":"https://doi.org/10.1115/1.4048752","authors":["Andrija Milojević","Sebastian Linß","Žarko Ćojbašić","Heikki Handroos"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-10-27T12:29:34Z","doi":"10.1115/1.4048752","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/icccnt61001.2024.10724587","name":"Design And Analysis Of Soft Robotic Gripper With Different Materials For Object Handling","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icccnt61001.2024.10724587","authors":["B Meenakshipriya","R.

Neuro-fuzzy techniques are the most widespread in developing gripper designs. In this study, the traditional gripper design is modified by adding a suitable cam that makes it compatible with the basic design, and an adaptive neuro-fuzzy inference system (ANFIS) is used in a MATLAB Simulink environment. The developed gripper investigates the follower path concerning the cam surface curve, and the gripper position is controlled using the developed ANFIS-PID. Three methods are examined in the developed ANFIS-PID controller: grid partitioning (genfis1), subtractive clustering (genfis2), and fuzzy C-means clustering (genfis3). The results show that the added cam can improve the gripping strength and that the ANFIS-PID model effectively handles the rise time and supported settling time. The developed ANFIS-PID controller demonstrates more efficient performance than Fuzzy-PID and traditional tuned-PID controllers. This proposed controller does not achieve any overshoot, and the rise time is improved by approximately 50–51%, and the steady-state error is improved by 75–95%, compared with Fuzzy-PID and tuned PID controllers. Moreover, the developed ANFIS-PID controller provides more stability for a wide range of set point displacements—0.05 cm, 0.5 cm, and 1.5 cm—during the testing period. The developed ANFIS-PID controller is not affected by disturbance, making it well suited for robotic gripper designs. Grip force control is also investigated using the proposed ANFIS-PID controller and compared with the Fuzzy-PID in three scenarios. The result from this force control proves objects’ higher actual gripping performance by using the proposed ANFIS-PID.","url":"https://doi.org/10.3390/automation6010004","authors":["Imad A.

Using differential scanning calorimetry (DSC), the reversible martensitic transformation to austenite of the three NiTi-based wires under study was emphasized by means of an endothermic minimum of the heat flow variation with temperature. NiTi and NiTiCu wire fragments were further tested for both WG-SME and CR-SME developed during the heating, from room temperature (RT) to different maximum temperatures selected from the DSC thermograms. The former tests revealed the capacity to repetitively lift various loads during repetitive heating, while the latter tests disclosed the repetitive development of shrinkage stresses during the repetitive heating of elongated wires. The tensile behavior of the three NiTi-based SMA wires was analyzed by failure and loading–unloading tests. The study disclosed the actuation capacity of NiTi and NiTiCu shape memory wires, which were able to develop work while being heated, as well as the resetting capacity of NiTiFe super-elastic wires, which can restore the initial undeformed shape of shape memory wires which soften while being cooled down.

In the traditional approach, the surgeon holds the endoscope and inserts the instruments into its lumen to reach the surgical window and perform the discectomy. Some steps, such as opening of the ligamentum flavum, require the help of an assistant to hold the endoscope while the surgeon is occupied handling other tools: this operation results in an inevitable waste of time. To overcome this and other drawbacks of the traditional procedure, a robotic approach has been investigated, which involves the use of a collaborative robot to hold the endoscope throughout the procedure. In this context, the gripper and its actuation system must be safe, reliable and lightweight.

However, the structures and material properties of existing pneumatic soft grippers limit their load capacity and manipulation range. In this article, inspired by sea lampreys, we present a pneumatic novel combined soft gripper to achieve a high load capacity and a large grasping range. This soft gripper consists of a cylindrical soft actuator and a detachable sucker. Three internal air chambers of the cylindrical soft actuator are inflated, which enables them to hold objects. Under vacuum pressure, the cylindrical soft actuator and the detachable sucker can both adsorb objects. A finite element model was constructed to simulate three inflation chambers for predicting the grasping range of the cylindrical soft actuator. The validity of the finite element model was established by an experiment. The mechanism of holding force and adsorption force were analyzed. Several groups of experiments were conducted to determine adsorption range, holding force, and adsorption force. In addition, practical applications further indicated that the novel combined soft gripper has a high load capacity (10.85 kg) at a low pressure (16 kPa) and a large grasping range (minimum diameter of the object: d = 6 mm), being able to lift a variety of objects with different weights, material properties, and shapes.","url":"https://doi.org/10.3390/act11010003","authors":["Dan Wang","Xiaojun Wu","Jinhua Zhang","Yangyang Du"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-12-28T01:18:15Z","doi":"10.3390/act11010003","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1016/j.apmr.2024.02.145","name":"Orientation Estimation of Robotic Gripper to Grasp Activities of Daily Living (ADL) Object Using YOLOv5-OBB","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.apmr.2024.02.145","authors":["Avinash Rajendra","Inga Wang","Mohammad Rahman"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-03T06:46:40Z","doi":"10.1016/j.apmr.2024.02.145","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1109/tro.2022.3224774","name":"Anthropomorphic Twisted String-Actuated Soft Robotic Gripper With Tendon-Based Stiffening","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tro.2022.3224774","authors":["Revanth Konda","David Bombara","Steven Swanbeck","Jun Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-12-02T20:59:20Z","doi":"10.1109/tro.2022.3224774","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.5391/jkiis.2012.22.1.22","name":"Design and Analysis of Ball Screw-driven Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.5391/jkiis.2012.22.1.22","authors":["Byoung-Ho Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-05-30T07:25:31Z","doi":"10.5391/jkiis.2012.22.1.22","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/icect61618.2024.10581172","name":"Design and Development of a Soft Robotic Gripper for Precision Control for Biomedical Applications","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icect61618.2024.10581172","authors":["Mohammad Qasim Shahid","Faisal Amin","Ahmad Abdullah Haris","Hussain Al Faisal","Ali Imran","Muhammad Farrukh Qureshi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-08T17:28:09Z","doi":"10.1109/icect61618.2024.10581172","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1109/3468.833099","name":"Design fundamentals of a reconfigurable robotic gripper system","source":"crossref","abstract":"","url":"https://doi.org/10.1109/3468.833099","authors":["R.

In addition, some simulation tools enable the prediction of potential defects and failures caused by residual stresses prior to manufacturing. In this study, a systematic workflow combining topology optimization (TO), laser powder bed fusion (PBF-LB/M), and hybrid post-processing is presented for the development of a robotic arm gripper. Using finite element (FE)-based TO, the original gripper geometry was redesigned to achieve a 65% mass reduction, decreasing the component weight from 570 to 192 g, while maintaining structural integrity. Residual stress accumulation and potential distortion occurring during PBF-LB/M were predicted using inherent-strain-based simulations, including the stress relief achieved by post–heat treatment scenario. The optimized design was manufactured using AlSi10Mg powder via PBF-LB/M, followed by 300°C for 2 h annealing, and subsequently refined through drilling, tapping, and surface finishing as part of a hybrid AM approach. Post-processing reduced the surface roughness from 3.4 (as-built) to 0.035 µm on functional contact regions, enabling precise joint compatibility. This study provides a transferable engineering framework that integrates computational design, distortion prediction, and hybrid manufacturing to realize lightweight, functionally efficient structures for robotic applications.","url":"https://doi.org/10.1177/1045389x261440825","authors":["Kagan Murat Purlu","Muhammed Taha Yildiz","Nazim Babacan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-18T08:33:43Z","doi":"10.1177/1045389x261440825","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:32.659Z"},{"id":"doi:10.1007/s12541-019-00199-6","name":"A 3D Printed Paper-Based Thermally Driven Soft Robotic Gripper Inspired by Cabbage","source":"crossref","abstract":"","url":"https://doi.org/10.1007/s12541-019-00199-6","authors":["Fuwen Hu","Limei Lyu","Yunhua He"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-08-19T10:02:51Z","doi":"10.1007/s12541-019-00199-6","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/lra.2023.3325714/mm2","name":"Lightweight and Powerful Vacuum-Driven Gripper With Bioinspired Elastic Spine_supp3-3325714.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2023.3325714/mm2","authors":["Zhuang Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-10-19T14:24:30Z","doi":"10.1109/lra.2023.3325714/mm2","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/tro.2022.3200550/mm1","name":"supp1-3200550.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tro.2022.3200550/mm1","authors":["Pei Jiang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-09-14T15:36:56Z","doi":"10.1109/tro.2022.3200550/mm1","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1016/s0016-5107(26)01304-0","name":"466 FIRST-IN-HUMAN USE OF A NEXT-GENERATION ROBOTIC GRIPPER PROVIDING TRACTION AND CLOSURE DURING COLORECTAL ESD","source":"crossref","abstract":"","url":"https://doi.org/10.1016/s0016-5107(26)01304-0","authors":["Sanghyun Kim","Bomee Lee","Han Jo Jeon","Hyuk Soon Choi","Yoon Tae Jeen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-01T10:48:54Z","doi":"10.1016/s0016-5107(26)01304-0","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:31.725Z"},{"id":"doi:10.1109/icacc63692.2024.10845375","name":"Effect of Pneumatic Based Hybrid Robotic Gripper for Safer Handling of Complex Geometries","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icacc63692.2024.10845375","authors":["Santhosh Sivaraj","Ajay Ravi","Bibin Joe Jose","Gobinath Velu Kaliyannan","Rajkamal Sivakumar","Riya Catherine Amalraj"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-01-22T18:48:25Z","doi":"10.1109/icacc63692.2024.10845375","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1109/iros.2014.6943195","name":"A study on data-driven in-hand twisting process using a novel dexterous robotic gripper for assembly automation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros.2014.6943195","authors":["Fei Chen","Ferdinando Cannella","Carlo Canali","Mariapaola D'Imperio","Traveler Hauptman","Giuseppe Sofia","Darwin Caldwell"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-11-12T22:48:34Z","doi":"10.1109/iros.2014.6943195","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1007/978-981-97-5621-6_13","name":"Dynamic Analysis of Underactuated Soft Robotic Gripper for Space Applications","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-97-5621-6_13","authors":["Saloni Malviya","Ankit Sharma","Jay Kassa","Deep Karia","Hemant Arora"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-19T14:25:51Z","doi":"10.1007/978-981-97-5621-6_13","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:31.829Z"},{"id":"doi:10.1109/lra.2022.3192653","name":"Single-Fingered Reconfigurable Robotic Gripper With a Folding Mechanism for Narrow Working Spaces","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2022.3192653","authors":["Toshihiro Nishimura","Tsubasa Muryoe","Yoshitatsu Asama","Hiroki Ikeuchi","Ryo Toshima","Tetsuyou Watanabe"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-07-20T19:32:11Z","doi":"10.1109/lra.2022.3192653","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/ic3ecsbhi67834.2026.11468966","name":"Hybrid Force and Torque Control of a Four-Finger Robotic Gripper Using Pid and Tactile Feedback in Simulink Environment","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ic3ecsbhi67834.2026.11468966","authors":["Azam Ameen","Mishkat Nizami","Mohd.

Since fruits have a delicate and fragile surfaces, it is vital to have a gripper with a smooth contact surface that can apply the right amount of force to pick the fruits without causing any bruising that can degrade the crop's quality. Hence, this paper proposes a robotic arm gripper design for the crop-picking mechanism using a force sensor as the main component of the Arduino Uno embedded system.

The gripper minimizes environmental disturbance by moving its fingers tangentially along an object’s surface while setting the grasp, in contrast to conventional grippers that approach perpendicularly. Each SCF-EM finger features an eversion sleeve actuated by two concentrically placed precurved flexures between its inner and outer sides, synchronized via a cable–pulley system. This constitutes as a mechanically actuated eversion mechanism–driven not by pneumatic pressure, as in traditional designs, but by advancing an internal flexure from its base to push against the sleeve interior. A prototype gripper, equipped with three SCF-EM fingers, was manufactured for grasping tomatoes piled in a crate. To evaluate its performance, three key metrics were defined and experimentally validated. The results show (1) a 100% grasp success rate for the specified task, demonstrated on a robotic test setup, (2) low induced disturbance forces—1.7 N normal and 1.5 N tangential—sufficiently gentle to avoid product damage, and (3) a 10.0 N pull-out force, ample for lifting tomatoes, corresponding to 4–10× their weight. These results demonstrate the SCF-EM gripper’s effectiveness for delicate object handling in confined environments and highlight the potential of mechanically driven eversion mechanisms.","url":"https://doi.org/10.1115/1.4071575","authors":["A.

A back-drivable pneumatic underactuated robotic gripper (PURG), based on the pneumatic cylinder and underactuated finger mechanism, is presented to accomplish the above goals. A feedforward grasping force control method, based on the learned kinematics of the underactuated finger mechanism, is proposed to achieve sensor-less grasping force control. To enhance the grasping force control accuracy, a state-based actuating force modeling method is presented to compensate the hysteresis error which exists in the transmission mechanism. Actuating force control experiment is performed to validate the effectiveness of the state-based actuating pressure modeling method. Results reveal that compared with the non-state-based modeling method, the proposed state-based actuating force modeling method could reduce the modeling error and control error by about 37.0% and 77.2%, respectively. Results of grasping experiments further reveal that grasping force could be accurately controlled by the state-based feedforward control model in a sensor-less approach.

A Wheelchair Mounted Robotic Arm (WMRA) will assist these individuals to eat, drink, and move objects as needed. This paper presents the design of a new WMRA as well as the analysis of its function. The design is side-mounted onto either a normal or power wheelchair, and incorporates a slim profile to allow ease of passage through doorways and be otherwise unobtrusive. The arm is easily removable, with assistance, for storage or travel. The mechanical design utilizes a belt and pulley system for remote actuation of each joint, driven by DC Gearmotors located in the base of the arm. This helps to shift the weight closer to the wheelchair and to maintain the required speed, torque and inertia while actively driving each joint of the robot. The end-effector is a unique design, intended to have the adaptability to securely lift a large variety of objects. Grasping simulations were performed on several standard objects which might be encountered daily.

These limitations make traditional approaches less effective in real-world agricultural settings, where conditions are unpredictable and fruits require careful, adaptive handling. Moreover, most existing studies do not incorporate a Convolutional Neural Network (CNN) to detect confidence in the planning process, often treating perception and motion planning as isolated components rather than a unified system. To overcome these challenges, this study proposes a data-driven approach to trajectory optimization that integrates visual perception based on CNN confidence levels, gripper type with different actuation technologies, and fruit orientation, parameters that significantly influence harvesting efficiency. Two multivariate regression models were developed, one specifically for firm fruits such as oranges and the other for soft fruits such as strawberries. The models predict trajectory length using three input variables: CNN detection confidence, actuator type, which includes three-finger and two-finger grippers, and fruit orientation angles ranging from 50°–130°. The non-linear influence of orientation is captured through polynomial terms. A total of 46 experimental trials were conducted for each fruit type using a robotic platform under controlled conditions. The regression outputs revealed that CNN confidence had a strong influence on trajectory length reduction, while orientation had a more severe impact on strawberries due to their delicate structure. In comparison to baseline trajectories, the optimized A* planner, guided by regression coefficients, curtailed trajectory lengths by 11% for strawberries and 14% for oranges. Moreover, the positional accuracy incre ased by 15% and 12%, respectively. The higher predictive accuracy was attained by the models (R 2 = 0.89 and 0.82; RMSE = 3.2 cm and 4.7 cm for strawberries and oranges, respectively). These results demonstrate that heuristic planning, combined with statistical modeling, enhances motion reliability and spatial efficiency in autonomous fruit picking.","url":"https://doi.org/10.1088/2631-8695/ae0ddc","authors":["Sadaf Zeeshan","Muhammad Ali Ijaz Malik","Tauseef Aized","Akbar Ali","Simran Ejaz","Faiza Javaid"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-30T22:53:03Z","doi":"10.1088/2631-8695/ae0ddc","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:26.467Z"},{"id":"doi:10.1109/lra.2023.3325714/mm3","name":"Lightweight and Powerful Vacuum-Driven Gripper With Bioinspired Elastic Spine_supp1-3325714.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2023.3325714/mm3","authors":["Zhuang Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-10-19T14:24:30Z","doi":"10.1109/lra.2023.3325714/mm3","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1007/978-3-030-60337-3_30","name":"Algorithms of Posteriori Multi-objective Optimization for Robotic Gripper Design","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-030-60337-3_30","authors":["Quyen Vu","Andrey Ronzhin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-09-29T23:08:26Z","doi":"10.1007/978-3-030-60337-3_30","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1007/978-981-19-3716-3_44","name":"Design of Pneumatically Actuated Soft Robotic Gripper for Gripping Cylindrical Objects of Varying Diameters","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-19-3716-3_44","authors":["Monalisa Sharma","Shubhashis Sanyal"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-10-04T00:02:41Z","doi":"10.1007/978-981-19-3716-3_44","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/ei250167.2020.9347270","name":"A Soft-Robotic Gripper for Ultra-High-Voltage Transmission Line Operations","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ei250167.2020.9347270","authors":["Yishan Chen","Zhonggui Fang","Sicong Liu","Yushuang Wang","Cheng Zhong","Chuanxiong Cai","Yuan Zhang","Ying Wei","Zheng Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-02-17T20:15:45Z","doi":"10.1109/ei250167.2020.9347270","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1007/978-3-030-63486-5_41","name":"One-Shot 3D Printed Underactuated Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-030-63486-5_41","authors":["Jordan Cormack","Mohammad Fotouhi","Guy Adams","Anthony Pipe"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-12-02T06:03:26Z","doi":"10.1007/978-3-030-63486-5_41","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1109/lra.2025.3583612/mm5","name":"Venus Flytrap-Inspired Electromagnetically Driven Bistable Gripper for Fast Envelope Grasping_supp1-3583612.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2025.3583612/mm5","authors":["Bin Tang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-27T13:47:25Z","doi":"10.1109/lra.2025.3583612/mm5","addedAt":"2026-08-31T06:34:16.868Z","updatedAt":"2026-08-31T06:34:16.868Z"},{"id":"doi:10.1111/j.1937-5956.2006.tb00247.x","name":"Throughput Optimization in Constant Travel‐Time Dual Gripper Robotic Cells with Parallel Machines","source":"crossref","abstract":"Constant travel‐time robotic cells with a single gripper robot and with one or more machines at each processing stage have been studied in the literature.

The objective is to find a cyclic sequence of robot moves that minimizes the long‐run average time to produce a part or, equivalently, maximizes the throughput. We provide a structural analysis of cells with one or more machines per processing stage to obtain first a lower bound on the throughput and, subsequently, an optimal solution under conditions that are common in practice.

These constraints present major obstacles to achieving safe and effective force control in demanding applications such as Minimally Invasive Surgery (MIS) and space exploration, where direct force measurement is often impractical. To address these challenges, this work considers a CM based gripper system as a testing apparatus for providing real-time, force feedback via structural deformation as a visual cue, thereby communicating force information without embedded sensors. Thus, this research characterizes the CM-based force feedback capabilities and subsequently develops a Machine Learning (ML) model to predict gripping force information, an important factor to advance the CM-gripper towards a future computer-assisted force feedback system.The study adopted a two-phase approach to bridge mechanical characterization with intelligent force prediction of a compliant mechanism (CM) gripper. In the first phase (Paper 1), the force-deflection properties of a CM gripper are experimentally characterized, revealing non-linear relationships between structural deformation and pinch forces. The nonlinearity is attributed to plastic deformation that was observed in the experiments due to excessive actuation. This finding redefined the experimental conditions to remain within the elastic region. In a separate work, the experiments were repeated under these requirements and showed linear agreement, which enables a linear based visual force feedback system.These findings directly inform the second phase (Paper 2), where the established relationships guide the selection and training of machine learning models. The experimental data from Paper 1 served as the foundation for understanding the design parameters for ML model development. In the work presented in Paper 2, ML models were systematically developed and verified against experimental data for pinch force prediction. The ML based research also employed a multi-metric evaluation framework - combining performance, absolute error and execution time visualized via radar charts to address critical gaps left by prior studies that rely on single performance indicators. Out of the seven ML models tested, the Weighted Regression demonstrated the best overall performance (Radar Chart Area = 0.95: R 2 = 96.27%, Mean Absolute Error = 0.51N, Execution Time = 1.41 s).This research developed a deformation-based ML-driven model to translate visual cues from a compliant mechanism gripper to pinch force prediction. This work forms a critical component of a larger research initiative aiming to integrate the ML model with image processing software to create a CM-gripper system equipped with real time computer-assisted force feedback capabilities. Such advances pave the way for future evaluations of two distinct force feedback systems using the CM based gripper system as a testing apparatus, specifically (a) human-assisted gripper manipulation, where force predictions are graphically overlaid to guide users and (b) fully automated ML-controlled gripper system that autonomously adjusts and maintains the required pinch force without user intervention. Collectively, this research moves this field closer to an intelligent, sensor-less robotic manipulation system.","url":"https://doi.org/10.25394/pgs.29695529","authors":["Mohanty, Vineet"],"tags":["Solid mechanics","Mechanical engineering not elsewhere classified","Machine learning not elsewhere classified"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.25394/pgs.29695529","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.25394/pgs.29670068.v1","name":"Mechanical Intelligence From Structural Multistability","source":"datacite","abstract":"Systems in nature exhibit complex behaviors and unique functionalities by tuning their global properties, shapeshifting into functional forms, sensing various inputs, and adapting to external stimuli.

However, the models pre-trained on such data can be suboptimal for robot learning due to the significant visual gap between human hands and those of different robots. To remedy this, we propose H2R, a human-to-robot data augmentation pipeline that converts egocentric human videos into robot-centric visual data. H2R estimates human hand pose from videos, retargets the motion to simulated robotic arms, removes human limbs via segmentation and inpainting, and composites rendered robot embodiments into the original frames with camera-aligned geometry. This process explicitly bridges the visual gap between human and robot embodiments during pre-training. We apply H2R to augment large-scale egocentric human video datasets such as Ego4D and SSv2. To verify the effectiveness of the augmentation pipeline, we introduce a CLIP-based image-text similarity metric that quantitatively evaluates the semantic fidelity of robot-rendered frames to the original human actions. We evaluate H2R through comprehensive experiments in both simulation and real-world settings. In simulation, H2R consistently improves downstream success rates across four benchmark suites-Robomimic, RLBench, PushT, and CortexBench-yielding gains of 1.3%-10.2% across different visual encoders and policy learning methods. In real-world experiments, H2R improves performance on UR5 and dual-arm Franka/UR5 manipulation platforms, achieving 3.3%-23.3% success rate gains across gripper-based, dexterous, and bimanual tasks. We further demonstrate the potential of H2R in cross-embodiment generalization and its compatibility with vision-language-action models. These results indicate that H2R improves the generalization ability of robotic policies by mitigating the visual discrepancies between human and robot domains.","url":"https://doi.org/10.48550/arxiv.2505.11920","authors":["Li, Guangrun","Lyu, Yaoxu","Liu, Zhuoyang","Hou, Chengkai","Zhang, Jieyu","Zhang, Shanghang"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2505.11920","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.48550/arxiv.2603.12967","name":"Language-Grounded Decoupled Action Representation for Robotic Manipulation","source":"datacite","abstract":"The heterogeneity between high-level vision-language understanding and low-level action control remains a fundamental challenge in robotic manipulation.

LaDA introduces a fine-grained intermediate layer of three interpretable action primitives--translation, rotation, and gripper control--providing explicit semantic structure for low-level actions.

However, dense future prediction introduces visual redundancy and accumulates errors, causing long-horizon plan drift. Meanwhile, recent sparse methods typically represent visual foresight using high-level semantic subtasks or implicit latent states. These representations often lack explicit kinematic grounding, weakening the alignment between planning and low-level execution. To address this, we propose StructVLA, which reformulates a generative world model into an explicit structured planner for reliable control. Instead of dense rollouts or semantic goals, StructVLA predicts sparse, physically meaningful structured frames. Derived from intrinsic kinematic cues (e.g., gripper transitions and kinematic turning points), these frames capture spatiotemporal milestones closely aligned with task progress. We implement this approach through a two-stage training paradigm with a unified discrete token vocabulary: the world model is first trained to predict structured frames and subsequently optimized to map the structured foresight into low-level actions. This approach provides clear physical guidance and bridges visual planning and motion control. In our experiments, StructVLA achieves strong average success rates of 75.0% on SimplerEnv-WidowX and 94.8% on LIBERO. Real-world deployments further demonstrate reliable task completion and robust generalization across both basic pick-and-place and complex long-horizon tasks.","url":"https://doi.org/10.48550/arxiv.2603.12553","authors":["Jin, Minghao","Liao, Mozheng","Han, Mingfei","Li, Zhihui","Chang, Xiaojun"],"tags":["Robotics (cs.RO)","Computer Vision and Pattern Recognition (cs.CV)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2603.12553","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.5075/epfl-thesis-9184","name":"Synthesis of Novel Integrated Actuators Powered by Shape Memory Alloys","source":"datacite","abstract":"In the modern age of miniaturisation, Smart Materials, a type of material that reacts mechanically to a certain stimulus, have become an integral part of this revolution. Among these materials, Shape Memory Alloys (SMAs), which have the highest volumetric work density, are the ideal candidate in creating lightweight and miniature actuators. These alloys, after being deformed, are able to revert back to their original shape when exposed to heat. This exotic behaviour has allowed them to be the core active component in a plethora of applications such as grippers, bio-mimetic robots and surgical instruments. Despite their high work density, their implementation comes with some challenges. While the Shape Memory Effect (SME), the ability to recover strain when a thermal load is applied, is a remarkable behaviour, it is also a complex and multi-physical one. This complicates their design and makes it difficult to predict their behaviour. Furthermore, these alloys are only able to recover strain when deformed at low temperatures. This implies that a biasing element is required to exploit these materials in reversible actuators. Due to these limitations, the work density of SMAs, when implemented as actuators in robotic systems, are often much lower than their theoretical maximum. In this thesis, the various types of SMA actuator implementations from different applications are examined to understand the design requirements and subsystems that are necessary to build an actuator. A holistic approach is, then, used to construct a design methodology to create highly integrated actuators in the hopes of preventing the work density degradation present in traditional SMA-based systems. Here, in this work, the identified subsystems of the SMA actuator are combined to serve as a multi-functional element in the novel integrated actuator. The work employs different strategies to integrate the SMA actuator into robotic systems while also proposing adapted sizing methodologies. The resulting SMA-powered system can be sized to be lightweight, compact and dynamic. Various case studies are presented that utilise the proposed holistic design approach and sizing methodologies to serve as a proof-of-concept and to validate the methodology. In this work, compliant and flexure-based mechanisms are exploited to exclude the need for a dedicated biasing element and create lightweight SMA-powered grippers to demonstrate the advantages of the proposed methodology. Additionally, utilising the mechanical behaviour of the SME, a lightweight mechanically-controlled crawling robot is designed and implemented. Furthermore, with the help of topology optimization and kirigami-inspired design, the work details the creation of compliant SMA structures that allow the material to generate multiple outputs while remaining compact and easy to assemble. Lastly, a novel bistable gripper is designed and sized to experimentally validate the design methodologies proposed in this work. The work demonstrates the different areas in which the degradation of the work density occur in traditional SMA systems. In this regard, design methodologies accompanied with sizing strategies are proposed that allows the creation of lightweight, high bandwidth and integrated SMA-based robotic systems. The results in this thesis, reveal the extraordinary value of SMAs in creating lightweight robotic systems and presents various strategies to allow the further integration of the alloy within the system.","url":"https://doi.org/10.5075/epfl-thesis-9184","authors":["Thomas, Sean"],"tags":["Shape Memory Alloys","Artificial Muscles","Compliant Mechanisms","Flexures","Mechanical-Intelligence","Buckled Beam","Topology Optimisation","Kirigami"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.5075/epfl-thesis-9184","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.48550/arxiv.2510.11036","name":"XGrasp: Gripper-Aware Grasp Detection with Multi-Gripper Data Generation","source":"datacite","abstract":"Real-world robotic systems frequently require diverse end-effectors for different tasks, however most existing grasp detection methods are optimized for a single gripper type, demanding retraining or optimization for each novel gripper configuration.

To resolve data scarcity, we augment existing single-gripper datasets with multi-gripper annotations by incorporating the physical characteristics and closing trajectories of diverse grippers.

Although substantial efforts have targeted parallel-gripper and single-hand grasping, dexterous grasping for bimanual robots remains underexplored, with data being a primary bottleneck.

Therefore, in industrial applications such as factory automation, where the manipulation of diverse objects is required, the gripper needs to be frequently replaced. Granular grippers represent a considerable step toward highly adaptable manipulators. Their main feature is their ability to reliably grasp objects of different shapes, sizes, and surface properties and even multiple objects at a time without the need for reconfiguration. Typically, a granular gripper comprises a granulate contained in a flexible membrane. In such a state, the granular material can flow when deformed. Thus, when the gripper is pressed onto an object, it deforms, adapting to its shape. If the air is evacuated from the gripper, the pressure difference between the ambient and the interior of the gripper causes the gripper bag to contract and compress the grains. The granulate then jams, i.e., it adopts a mechanically stable state, which makes the gripper rigid. During this transition from a liquid-like to a solid-like state, the gripper pinches the object, applying sufficient force for gripping and lifting it. If air evacuation is ceased, the gripper bag relaxes, the granulate returns to a malleable state, and the object is released. Despite representing a promising technology, current granular grippers are not yet fully developed and optimized, and their use in industrial applications remains scarce. Since most research on granular grippers has focused on the macroscopic response of these systems when changing its parameters (granular material, material of the membrane, differential pressure), a comprehensive understanding of the particle-scale processes that underline the operation of these grippers is still lacking. Understanding the relation between the macroscopic performance of granular grippers and the microscopic structure and dynamics of the granular material throughout a gripping cycle is essential for improving their functionality and optimizing their design. This dissertation describes the mechanical phenomena in granular materials underlying the functionality of granular grippers. To that aim, experiments and X-ray imaging are applied. The insights gained are then applied to enhance the operation of granular grippers. As a first step, a modular granular gripper is developed that allows for automatic holding force measurements suitable for use in X-ray scanners. The apparatus is then used to investigate the effect of particle stiffness on the maximum holding force achieved by granular grippers. A new mode of operation of these grippers is discovered when soft instead of rigid particles are used, which significantly increases the maximum holding force produced by the gripper. A gripper filled with soft particles undergoes a considerable volume reduction due to particle softness, which leads the gripper to press the objects firmly. This leads to large normal forces and, therefore, significant friction between the gripper and the object. Particle softness also improves the gripper's conformation around protrusions of the gripped object, reinforcing geometrical interlocking between the gripper and object. In a second step, the effect of particle size on the suction mechanism in granular grippers is studied. It is demonstrated that the activation of suction is connected to the size of the particles within the gripper. The gripper closely conforms to the object when small particles are used. In this case, airtight seals can form between the gripper and the object; therefore, suction is activated. If the gripper is filled with large particles, the gripper's bag is not in full contact with the object, leaving gaps between the gripper's bag and the object. If these gaps are not sealed, the pressure within such cavities equalizes with ambient pressure, hindering the suction mechanism from activating.

However, existing modular magnetic platforms often depend on workspace collisions for reconfiguration, employ bulky three-dimensional electromagnetic systems, and lack robust single-module control, which limits their applicability in biomedical settings. In this work, we present a modular magnetic millirobotic platform comprising three cube-shaped modules with embedded permanent magnets, each designed for a distinct functional role: a free module that supports self-assembly and reconfiguration, a fixed module that enables flip-and-walk locomotion, and a gripper module for cargo manipulation. Locomotion and reconfiguration are actuated by programmable combinations of time-varying two-dimensional uniform and gradient magnetic field inputs. Experiments demonstrate closed-loop navigation using real-time vision feedback and A* path planning, establishing robust single-module control capabilities. Beyond locomotion, the system achieves self-assembly, multimodal transformations, and disassembly at low field strengths. Chain-to-gripper transformations succeeded in 90% of trials, while chain-to-square transformations were less consistent, underscoring the role of module geometry in reconfiguration reliability. These results establish a versatile modular robotic platform capable of multimodal behavior and robust control, suggesting a promising pathway toward scalable and adaptive task execution in confined environments.","url":"https://doi.org/10.48550/arxiv.2602.19346","authors":["Oyono, Erik Garcia","Lin, Jialin","Zhang, Dandan"],"tags":["Robotics (cs.RO)","Systems and Control (eess.SY)","FOS: Computer and information sciences","FOS: Electrical engineering, electronic engineering, information engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2602.19346","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:31.727Z"},{"id":"doi:10.5281/zenodo.18746675","name":"Vibrotactile Teleoperation with Hand Gesture Recognition","source":"datacite","abstract":"The present project develops an immersive teleoperation system for the remote control of a robotic arm.

Robotic harvesting has emerged as a promising alternative; however, evaluating and training soft grippers for delicate fruits remains difficult due to the highly variable mechanical properties of natural produce. This makes it difficult to establish reliable benchmarks or data-driven control strategies. Existing testing practices rely on large quantities of real fruit to capture this variability, leading to inefficiency, higher costs, and waste. The methodology presented in this work aims to address these limitations by developing tunable soft physical twins that emulate the stiffness characteristics of real fruits at different ripeness levels. A fiber-reinforced pneumatic physical twin of a kiwi fruit was designed and fabricated to replicate the stiffness at different ripeness levels. Experimental results show that the stiffness of the physical twin can be tuned accurately over multiple trials (97.35 - 99.43% accuracy). Gripping tasks with a commercial robotic gripper showed that sensor feedback from the physical twin can reflect the applied gripping forces. Finally, a stress test was performed over 50 cycles showed reliable maintenance of desired stiffness (0.56 - 1.10% error). This work shows promise that robotic physical twins could adjust their stiffness to resemble that of real fruits. This can provide a sustainable, controllable platform for benchmarking and training robotic grippers.","url":"https://doi.org/10.48550/arxiv.2602.18661","authors":["Nadipineni, Saitarun","Pandiyan, Keshav","Althoefer, Kaspar","Hirai, Shinichi","Lalitharatne, Thilina Dulantha"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2602.18661","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:31.727Z"},{"id":"doi:10.5281/zenodo.18709719","name":"DESIGN AND DEVELOPMENT OF A LEAD SCREW GRIPPER FOR ROBOTIC APPLICATION","source":"datacite","abstract":"This paper gives details on the electromechanical design concept and prototype development of a lead screw linear actuated, parallel robotic gripper.

Anygrasp [1] and many other grasp synthesis methods are designed for rigid parallel grippers, and adapting them to soft grippers often fails to capture their unique compliant behaviors, resulting in data-intensive and inaccurate models. To bridge this gap, this paper proposes a novel framework to map grasp poses from a rigid gripper model to a soft Fin-ray gripper. We utilize Conditional Flow Matching (CFM), a generative model, to learn this complex transformation. Our methodology includes a data collection pipeline to generate paired rigid-soft grasp poses. A U-Net autoencoder conditions the CFM model on the object's geometry from a depth image, allowing it to learn a continuous mapping from an initial Anygrasp pose to a stable Fin-ray gripper pose. We validate our approach on a 7-DOF robot, demonstrating that our CFM-generated poses achieve a higher overall success rate for seen and unseen objects (34% and 46% respectively) compared to the baseline rigid poses (6% and 25% respectively) when executed by the soft gripper. The model shows significant improvements, particularly for cylindrical (50% and 100% success for seen and unseen objects) and spherical objects (25% and 31% success for seen and unseen objects), and successfully generalizes to unseen objects. This work presents CFM as a data-efficient and effective method for transferring grasp strategies, offering a scalable methodology for other soft robotic systems.","url":"https://doi.org/10.48550/arxiv.2602.17110","authors":["Parulekar, Tanisha","Shi, Ge","Pinskier, Josh","Howard, David","Chung, Jen Jen"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2602.17110","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.6084/m9.figshare.22767609.v1","name":"Random_Kirigami-SI.pdf from Geometric mechanics of ordered and disordered kirigami","source":"datacite","abstract":"The presence of cuts in a thin planar sheet can dramatically alter its mechanical and geometrical response to loading, as the cuts allow the sheet to deform strongly in the third dimension.

Overall our study of random kirigami sets the stage for controlling the shape and shielding the stresses in thin sheets using cuts.","url":"https://doi.org/10.6084/m9.figshare.22767609","authors":["Chaudhary, G.","Niu, L.","Han, Q.","Lewicka, M.","Mahadevan, L."],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.6084/m9.figshare.22767609","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.48550/arxiv.2501.16717","name":"Strawberry Robotic Operation Interface: An Open-Source Device for Collecting Dexterous Manipulation Data in Robotic Strawberry Farming","source":"datacite","abstract":"The strawberry farming is labor-intensive, particularly in tasks requiring dexterous manipulation such as picking occluded strawberries.

We propose a different philosophy: detect the failure during execution and apply a small corrective \"nudge\" that salvages the attempt without replanning. Our system layers a lightweight tactile-conditioned residual policy on top of a frozen VLA base policy. A GelSight-style tactile sensor mounted on the gripper fingers detects slip onset, contact asymmetry, and insufficient grasp force within 40 ms. These tactile features condition a residual action network that outputs a corrective ΔSE(3) displacement and gripper-width adjustment, which is added to the base policy's next commanded action. The residual policy is trained from 600 demonstrations (half successes, half near-failures) using a contrastive objective that separates correctable failures from irrecoverable ones. On a physical Franka Emika Panda across 12 household objects, our system converts 74% of would-be failures into successes, raising the overall grasp success rate from 81% (VLA alone) to 95%, with only 52 ms added latency per control step. Ablation studies confirm that both tactile feedback and the residual formulation are essential.","url":"https://doi.org/10.6084/m9.figshare.31341124.v2","authors":["R. Vasquez, Emily","M.

Failure to modulate force can lead to task failure or irreversible damage to the objects. Humans can precisely achieve this by adapting force from tactile feedback, even within a short period of physical contact. We aim to give robots this capability. However, commercial grippers exhibit high cost or high minimum force, making them unsuitable for studying force-controlled policy learning with everyday force-sensitive objects. We introduce TF-Gripper, a low-cost (~$150) force-controlled parallel-jaw gripper that integrates tactile sensing as feedback. It has an effective force range of 0.45-45N and is compatible with different robot arms. Additionally, we designed a teleoperation device paired with TF-Gripper to record human-applied grasping forces. While standard low-frequency policies can be trained on this data, they struggle with the reactive, contact-dependent nature of force regulation. To overcome this, we propose RETAF (REactive Tactile Adaptation of Force), a framework that decouples grasping force control from arm pose prediction. RETAF regulates force at high frequency using wrist images and tactile feedback, while a base policy predicts end-effector pose and gripper open/close action. We evaluate TF-Gripper and RETAF across five real-world tasks requiring precise force regulation. Results show that compared to position control, direct force control significantly improves grasp stability and task performance. We further show that tactile feedback is essential for force regulation, and that RETAF consistently outperforms baselines and can be integrated with various base policies. We hope this work opens a path for scaling the learning of force-controlled policies in robotic manipulation.

We built and evaluated an end‑to‑end pipeline that couples YOLOv8 object‑detection variants with Google’s Coral Edge TPU for real‑time recognition of white and brown chicken eggs. A bespoke dataset of 971 images (640 × 480 px) was captured under diverse backgrounds and lighting, annotated in YOLO format, and split 70 %/20 %/10 % for training, validation and testing. Five YOLOv8 models (n, s, m, l, x) were trained for 100 epochs with a batch size of 16. All models achieved very high accuracy (mAP50 = 0.98), but YOLOv8s produced the best F1–confidence pairing (F1 = 0.98 at 0.703 confidence), while YOLOv8n offered the lowest computational load. Converting the networks to TensorFlow‑Lite and compiling them for the Edge TPU boosted inference speed dramatically: YOLOv8n jumped from 2.4 FPS on Raspberry Pi 5 (PyTorch) to 13.8 FPS on Edge TPU, and YOLOv8s rose from 1.0 FPS to 4.1 FPS, with only marginal accuracy loss. Precision and recall remained ≥ 0.96 across all variants. These results demonstrate that lightweight YOLOv8 models, particularly the n‑variant, are suitable for embedded, robotics‑grade egg‑collection systems that demand real‑time performance without sacrificing detection quality.

A challenge that remains difficult until now is the ability to handle delicate objects that can be easily considered as defective due to their interaction with the gripper, such as the case for food products or finely machined parts. An interesting emerging approach to tackle this challenge is to rethink the origin of the problem, which is the fact that all conventional grippers are made of hard and rigid components that can easily damage objects during grasping if not precisely controlled based on reliable sensory feedback. Hence, creating gripper fingers from soft materials makes them inherently safe and relaxes the need for sophisticated sensing and complex control.

A challenge that remains difficult until now is the ability to handle delicate objects that can be easily considered as defective due to their interaction with the gripper, such as the case for food products or finely machined parts. An interesting emerging approach to tackle this challenge is to rethink the origin of the problem, which is the fact that all conventional grippers are made of hard and rigid components that can easily damage objects during grasping if not precisely controlled based on reliable sensory feedback. Hence, creating gripper fingers from soft materials makes them inherently safe and relaxes the need for sophisticated sensing and complex control.

We propose Graph-Fused Vision-Language-Action (GF-VLA), a framework that enables dual-arm robotic systems to perform task-level reasoning and execution directly from RGB and Depth human demonstrations. GF-VLA first extracts Shannon-information-based cues to identify hands and objects with the highest task relevance, then encodes these cues into temporally ordered scene graphs that capture both hand-object and object-object interactions. These graphs are fused with a language-conditioned transformer that generates hierarchical behavior trees and interpretable Cartesian motion commands. To improve execution efficiency in bimanual settings, we further introduce a cross-hand selection policy that infers optimal gripper assignment without explicit geometric reasoning. We evaluate GF-VLA on four structured dual-arm block assembly tasks involving symbolic shape construction and spatial generalization. Experimental results show that the information-theoretic scene representation achieves over 95 percent graph accuracy and 93 percent subtask segmentation, supporting the LLM planner in generating reliable and human-readable task policies. When executed by the dual-arm robot, these policies yield 94 percent grasp success, 89 percent placement accuracy, and 90 percent overall task success across stacking, letter-building, and geometric reconfiguration scenarios, demonstrating strong generalization and robustness across diverse spatial and semantic variations.","url":"https://doi.org/10.48550/arxiv.2508.05342","authors":["Li, Shunlei","Gao, Longsen","Wang, Jin","Che, Chang","Xiao, Xi","Cao, Jiuwen","Hu, Yingbai","Karimi, Hamid Reza"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2508.05342","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.6084/m9.figshare.31033166","name":"Design methodology of hydraulically-driven soft robotic gripper for a large and heavy object","source":"datacite","abstract":"This paper presents a design methodology of a hydraulically-driven soft robotic gripper for grasping a large and heavy object – approximately 10–20 kg with 20–30 cm diameter.

By automating more intimate interactions with foliage, in vivo, it would be possible to inject chemical and biological probes that reveal more phenotypes, such as water stress in response to varying environmental conditions, and visible gene expression to measure the success of gene engineering applications. To address this, we developed a soft robotic leaf gripper and stamping-injection method to improve foliar delivery of nanoscale synthetic and biological probes.

Advanced manipulation skills, such as finger-to-palm translation and palm-to-finger translation, enhance dexterity in multi-object grasping. These translational movements allow the fingers to transfer the grasped objects to the palm for storage, enabling the fingers to freely perform various pick-and-place tasks while the palm stores multiple objects. However, conventional grippers, although able to handle multiple objects simultaneously, lack this integrated functionality, which combines the palm's storage with the fingers' precise placement.

The proposed gripper consists of four fingers and an adaptive conveyor palm. The fingers sequentially grasp and transfer objects to the palm, where the objects are stored simultaneously, allowing the gripper to move multiple objects at once. Furthermore, by reversing this process, the fingers retrieve the stored objects and place them one by one in the desired position and orientation. A finger design for simple object translating and a palm design for simultaneous object storing are proposed and validated.

However, because of material and process limitations, FFF-printed soft robots often have a high effective stiffness and contain a large number of leaks, limiting their applications. We present an approach for the design and fabrication of soft, airtight pneumatic robotic devices using FFF to simultaneously print actuators with embedded fluidic control components. We demonstrated this approach by printing actuators an order of magnitude softer than those previously fabricated using FFF and capable of bending to form a complete circle. Similarly, we printed pneumatic valves that control a high-pressure airflow with low control pressure. Combining the actuators and valves, we demonstrated a monolithically printed electronics-free autonomous gripper. When connected to a constant supply of air pressure, the gripper autonomously detected and gripped an object and released the object when it detected a force due to the weight of the object acting perpendicular to the gripper. The entire fabrication process of the gripper required no posttreatment, postassembly, or repair of manufacturing defects, making this approach highly repeatable and accessible.

However, there are many tasks for which two hands are not enough, such as in surgery. For such tasks, a dyad of people is required. However, when not used to work together, a dyad collaboration can be intermittent, slow and prone to misunderstandings if relied solely on verbal cues. The current PhD thesis report concerns the design and control of foot interfaces to enable solo four-handed manipulations. In the first part, we present the platform design in five DoF, with position mapping and haptic force feedback. We tackle the known issue of fatigue when using position mapping, by partially compensating for the dynamics of the leg. Finally, we perform a series of feasibility validations on bipedal teleoperation in 3 and 4 and 5 DoF. In the second part, a behavioural study investigates a symmetric bipedal holding and transport of an object while working on it with the hands. This study sheds light to the human capacity to use the redundancy given by augmentation with the feet, to assist the task of the hands. We investigate the effect of shared-control for lower limb teleoperation. Two modalities are used: 1. synergistic control of two robotic arms with one foot, 2. force assistance. We evaluate these strategies in terms of objective and subjective metrics, such as physical and cognitive workload and fluency. Aiming at enabling individualized foot dexterous control, in the third part of the thesis, we addressed the problem of bio-mechanical coupling of foot rotations. This is done by detecting intention to grasp, and selectively easing this action while haptically constraining the foot gestures for tool alignment. A user study was conducted to evaluate our proposed approach in a surgical laparoscopic gripper. In the fourth and final part, we focus on investigating more demanding tasks for the feet, as well as the coordinated control of four hands, during hybrid-robotic laparoscopic surgery. One foot controls a camera, while the other one performs a grasping task. Noteworthy is that all four-arms can be controlled simultaneously. For easing the solo surgical task, we design haptic assistance, for autonomous grasping operated by the foot. Finally, we perform a systematic behavioural study to understand the effect of our haptic-shared-control, along with an assistance modality for camera tool-tracking. We cover uni-pedal, bipedal and four-handed task scenarios. Our main conclusion is that foot gestures can be conditioned with haptic feedback, to effectively control multiple degrees of freedom of a supernumerary robotic arm. Thereby enabling four-arm simultaneous manipulations. This is done specifically by leveraging 1. a foot kinesthetic haptic platform that allows for the use of two feet, 2. leg compensation, and virtual assistive impedance, which are useful to increase comfort and alleviate fatigue. 3. Hybridization of control mappings for foot gestures, with limited range of motion and oblique axes of rotation, 4. Haptic shared-control strategies for prehensile force assistance, coordination assistance, and DoF-individuation assistance. We found that robotic assistance is highly appreciated, and has an important role in simplifying four-handed tasks. Indeed, these are instrumental considerations to enable a more fluent, less demanding, and more performant interaction, in tasks where the feet are supplementing the task of hands.","url":"https://doi.org/10.5075/epfl-thesis-9286","authors":["Hernandez Sanchez, Jacob"],"tags":["Human Augmentation","Four Arm Manipulation","Four Handed Tasks","Foot Platform","Haptics","Robot Control","Feet","Teleoperation"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.5075/epfl-thesis-9286","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.26083/tuda-7682","name":"Point cloud based determination of the most suitable robot grasp position for batch size 1 part handling","source":"datacite","abstract":"In batch-size-one part handling scenarios, robotic grasping of diverse and previously unseen objects remains a considerable challenge. This task requires robots not only to perceive and identify objects in unstructured environments autonomously but also to infer the grasp configurations that are optimally adapted to the geometric characteristics of both the target object and the specific end effector. To address this problem, the present work proposes a modular and extensible framework for optimal grasp point estimation based on 3D point cloud input and predefined gripper configurations. The system is designed for vision-guided robotic manipulation and aims to detect, evaluate, and compare feasible grasp candidates across multiple gripper types to determine the most suitable grasp configuration. The framework supports gripper-specific grasping strategies and introduces a unified Grasp Suitability Score GSS that enables consistent evaluation and direct cross-gripper comparability. In its current implementation, the method focuses on parallel grippers. It reduces the 3D grasp evaluation problem to 2D contour-based analysis through plane segmentation and PCA-based projection of object point clouds. Candidate test points are generated via grid sampling within the 2D contour of the projected point cloud and are subsequently filtered based on collision constraints and minimum contact area criteria. The resulting feasible grasp points are scored based on their alignment with the object's center of mass and the extent of contact surface coverage, thereby producing a ranked list of grasp configurations. The configuration with the highest GSS score is selected as the globally optimal solution. Experimental validation was conducted based on both synthetic and real-world point clouds, including models derived from open-source grasping datasets and their corresponding 3D-printed parts. The evaluation covered several key performance dimensions: functional correctness, localization accuracy of the estimated grasp point, repeatability under identical input conditions, robustness to varying point cloud densities, and computational efficiency. Results demonstrate that the proposed method reliably identifies the most suitable grasp configuration, with localization deviations of less than 3 mm, and maintains consistent performance across various scenarios. Furthermore, the framework exhibits extensibility toward suction-based and adaptive grippers. Future work will focus on improving plane segmentation accuracy, incorporating inner contour features, enhancing parameter adaptability, and enabling deployment in fully reconstructed real-world scenes. The complete implementation, including models, point clouds, evaluation results, and all associated executable scripts, is publicly available in an open-source repository to support reproducibility and facilitate further research.","url":"https://doi.org/10.26083/tuda-7682","authors":["Liu, Hanyu"],"tags":["Robotic grasping","3D point cloud","Grasp point estimation","Parallel gripper","Vision-guided manipulation","620","621.3"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.26083/tuda-7682","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.48550/arxiv.2601.09163","name":"CEI: A Unified Interface for Cross-Embodiment Visuomotor Policy Learning in 3D Space","source":"datacite","abstract":"Robotic foundation models trained on large-scale manipulation datasets have shown promise in learning generalist policies, but they often overfit to specific viewpoints, robot arms, and especially parallel-jaw grippers due to dataset biases.

We report experimental results on a 20 kg object grasping and closed-loop control of the finger bending angle.","url":"https://doi.org/10.48550/arxiv.2601.09104","authors":["Yamamoto, Ko","Ishibashi, Kyosuke","Ishikawa, Hiroki","Azami, Osamu"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2601.09104","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.18419/darus-5612","name":"Digital Twin task logs for Collective Robotic Construction (CRC) — ROB|ARCH 2024","source":"datacite","abstract":"&lt;!doctype html&gt; &lt;html lang=\"en\"&gt; &lt;head&gt; &lt;meta charset=\"utf-8\" /&gt; &lt;meta name=\"viewport\" content=\"width=device-width, initial-scale=1\" /&gt; &lt;title&gt;Digital Twin task logs for Collective Robotic Construction (CRC) — ROB|ARCH 2024&lt;/title&gt; &lt;style&gt; :root{ --bg:#ffffff; --fg:#111827; --muted:#6b7280; --border:#e5e7eb; --codebg:#0b1020; --codefg:#e5e7eb; --link:#2563eb; } html,body{background:var(--bg); color:var(--fg); margin:0; font-family:system-ui,-apple-system,Segoe UI,Roboto,Helvetica,Arial,sans-serif; line-height:1.6;} main{max-width:980px; margin:0 auto; padding:32px 20px 64px;} h1,h2,h3{line-height:1.25; margin:1.2em 0 .5em;} h1{font-size:2rem; margin-top:0;} h2{font-size:1.35rem; border-top:1px solid var(--border); padding-top:1.1rem;} h3{font-size:1.1rem;} p{margin:.75em 0;} ul,ol{padding-left:1.3em;} code{font-family:ui-monospace,SFMono-Regular,Menlo,Monaco,Consolas,\"Liberation Mono\",\"Courier New\",monospace; font-size:.95em;} pre{background:var(--codebg); color:var(--codefg); padding:14px 16px; border-radius:10px; overflow:auto; border:1px solid rgba(255,255,255,.08);} pre code{color:inherit;} a{color:var(--link); text-decoration:none;} a:hover{text-decoration:underline;} hr{border:0; border-top:1px solid var(--border); margin:1.6em 0;} table{width:100%; border-collapse:collapse; margin:1em 0; font-size:.95rem;} th,td{border:1px solid var(--border); padding:10px 10px; vertical-align:top;} th{background:#f9fafb; text-align:left;} .muted{color:var(--muted);} &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;main&gt; &lt;h1&gt;Digital Twin task logs for Collective Robotic Construction (CRC) — ROB|ARCH 2024&lt;/h1&gt; &lt;h2&gt;Overview&lt;/h2&gt; &lt;p&gt; This repository contains a dataset of &lt;strong&gt;Digital Twin (DT) task logs&lt;/strong&gt; from a &lt;strong&gt;Collective Robotic Construction (CRC)&lt;/strong&gt; workshop held at &lt;strong&gt;ROB|ARCH 2024&lt;/strong&gt;.

Moreover, the existing upper limb rehabilitation paradigms often focus only on bulk motions with maximal force generation, neglecting on a more fine motor control over the whole spectrum of various force levels. Considering the fact that the focus on the upper extremity should be based on the finer control than lower extremity, an imbalance exists in the current rehabilitation regime. To balance this shortcoming and to achieve better overall results in rehabilitation training regime, a more refined and well-designed training system is required to ensure more practical and effective outcome with finer motor control as well as to quantitatively address the theoretical aspects of motor control.To address these issues in terms of developing a better rehabilitation platform as well as to deliver more quantifiable metrics, this study investigated application and development of a novel upper limb rehabilitation training system for the restoration of daily fine motor function for hemiparetic persons using assistive robotic approaches on rehabilitation instrumentation to effectively quantify human kinetic and dynamic motor functions at the elbow, forearm, and hand.Conventional Fitts' speed vs. accuracy trade-off (SAT) test was adapted for this research for both kinematic and dynamic aspects of human motor control. First, kinematic speed vs. accuracy trade-off (KSAT) test was performed at the elbow flexion and extension level, then dynamic speed vs. accuracy trade-off (DSAT) test was performed at the palmar force level, both with visual feedback.Specifically, four hypotheses will be tested in this research: (1) Stroke groups' log-linearity trend from KSAT test will follow Fitts' law with differing slopes from normal groups' performance. (2) Second hypothesis will test normal groups' log-linearity from DSAT test to see whether the dynamic aspects of Fitts' paradigm will correlate to conventional kinematic Fitts' type behavior. (3) Third hypothesis will test on the reproducibility of the direct hand grip force from extrinsic force signals at the forearm to see the functionality of the force myography (FMG) which detects extrinsic force signals at the end-effector sites. (4) Last hypothesis will test the stroke group's improvements in terms of important functional metrics produced by the devices to show the efficacy of the system.The overall system is called HARI (Hand and Arm Rehabilitation Interface) with accompanying subcomponents; MAST (Mechanical Arm Supporter and Tracker) for the base platform and lower arm movement detection with the embedded goniometer at the elbow, FMG (Force Myography) cuff sleeve for forearm musculature detection, and the Gripper for direct hand grip force detection. Instrumental development for HARI as a whole upper-limb rehabilitation system was successful, that all the individualsub-devices were able to gather a reliable and repeatable, high quality physiological data with good signalto-noise (SNR) as well as excellent patient comfortness, to the level of imminent marketability for hospital, laboratory, or home settings, as an efficient and innovative rehabilitation tool.Keywords - stroke, hemiparesis, paralysis, upper limb rehabilitation, kinematic, dynamic, Fitts' Law,fine-motor control.","url":"https://doi.org/10.7282/t36110s0","authors":["Kim, Nam-Hun"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2007","doi":"10.7282/t36110s0","addedAt":"2026-08-31T06:34:16.869Z","updatedAt":"2026-08-31T06:34:16.869Z"},{"id":"doi:10.1002/9781394402762.fmatter","name":"Neurodynamic Methods for Continuum Robot Control","source":"crossref","abstract":"","url":"https://doi.org/10.1002/9781394402762.fmatter","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-29T13:48:41Z","doi":"10.1002/9781394402762.fmatter","addedAt":"2026-08-31T06:34:19.808Z","updatedAt":"2026-08-31T06:34:19.808Z"},{"id":"doi:10.1016/b978-0-443-24778-1.00004-7","name":"Robot performance in the context of medical applications","source":"crossref","abstract":"","url":"https://doi.org/10.1016/b978-0-443-24778-1.00004-7","authors":["Kotaro Tadano","Kenji Kawashima"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-31T22:54:24Z","doi":"10.1016/b978-0-443-24778-1.00004-7","addedAt":"2026-08-31T06:34:19.808Z","updatedAt":"2026-08-31T06:34:19.808Z"},{"id":"doi:10.1016/j.ast.2026.112048","name":"Flexibility-driven aerodynamic performance in a bio-inspired four-wing, eight-segment, dual-actuator flapping mirco-robot","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.ast.2026.112048","authors":["Zin Min Khant","Pengzhen Guo","Xiaomin Wu","Zheng Chanru","Yun Chen","Shuangyu Wang","Linghao Li","Xueying Li","Songyuan Han","Haibo Gao","Zongquan Deng","Lifang Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-01T22:50:45Z","doi":"10.1016/j.ast.2026.112048","addedAt":"2026-08-31T06:34:19.808Z","updatedAt":"2026-08-31T06:34:19.808Z"},{"id":"doi:10.2514/6.2026-110084","name":"Evaluating the Reliability of Explainable Machine Learning for Spacecraft Actuator Fault Detection","source":"crossref","abstract":"","url":"https://doi.org/10.2514/6.2026-110084","authors":["Pranav Narayan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-18T14:00:26Z","doi":"10.2514/6.2026-110084","addedAt":"2026-08-31T06:34:19.808Z","updatedAt":"2026-08-31T06:34:19.808Z"},{"id":"doi:10.1038/s44182-026-00108-w","name":"Aerial and ground locomotion of winged drones powered by a single actuator","source":"crossref","abstract":"Abstract Multimodal drones combining aerial and terrestrial mobility offer adaptability and extended operational range across diverse environments. However, most existing multimodal drones rely on multiple actuators that add mass and complexity while offering limited terrestrial locomotion capabilities. Here, we introduce a multimodal winged drone driven by only a single actuator, capable of ground locomotion, flight, and ground-to-air transition by either rolling or jumping. The actuator is based on a novel transmission system that enables control of its rotational direction to switch between different locomotion modes. In one direction, the actuator drives a propeller that generates forward thrust for flight and (passive) wheeled locomotion on the ground, while in the other direction it activates a spring-leg mechanism that enables jumping by storing and releasing elastic energy. We show that the winged drone can perform fast wheeled locomotion on flat surfaces, consecutive jumps across diverse terrains, as well as take-off from a runway or jumping from a spot. Experimental characterization shows that runway take-off offers greater energy efficiency, while jumping take-off is more space-efficient and less dependent on ground conditions. The proposed actuation method enables simple and effective versatility for locomotion in diverse environments, thus extending the operational range of winged drones.","url":"https://doi.org/10.1038/s44182-026-00108-w","authors":["Won Dong Shin","Hoang-Vu Phan","Simon L.

Conventional humanoid systems often rely on complex joint architectures that increase weight, cost, and control difficulty, while simplified designs risk instability during gait transitions. This paper introduces three alternative kinematic concepts for two-legged locomotion, each evaluated through formal analysis and prototype testing. Unlike prior descriptive studies, the work advances beyond simulation by deriving the inverse kinematics of the proposed mechanisms and applying Zero Moment Point (ZMP) stability criteria to quantify balance. Among the designs, a non-anthropomorphic configuration employing linear guides and a parallelogram linkage (Concept C) demonstrates superior stability, reduced control complexity, and balanced cost efficiency. Experimental validation with a fabricated prototype confirmed simulation predictions, showing a 45% reduction in power consumption compared to Concept A and ZMP deviations contained within 1.1 mm versus 4.2 mm for Concept A. Load capacity tests further validated scalability, sustaining 2.0 kg with stable torque distribution. By reframing the crossed-foot gait and parallelogram linkage as targeted solutions to actuator minimization and base stabilization, this study establishes a novel contribution to lightweight bipedal locomotion. The results provide a foundation for future development of compact, energy-efficient walking robots capable of navigating uneven terrain with reduced hardware demands, enabling inspection and service platforms that are approximately 30% cheaper and 25% more energy-efficient than current humanoid models.","url":"https://doi.org/10.2139/ssrn.6674359","authors":["Danish Abdullah"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-08T13:53:47Z","doi":"10.2139/ssrn.6674359","addedAt":"2026-08-31T06:34:19.809Z","updatedAt":"2026-08-31T06:34:19.809Z"},{"id":"doi:10.2514/6.2026-1061","name":"Nonlinear Actuator Modeling and Describing Function Analysis for Active Flutter Suppression","source":"crossref","abstract":"","url":"https://doi.org/10.2514/6.2026-1061","authors":["Mriganka S.

The SEMA comprises soft polymeric substrates with stretchable electrical circuits, and is actuated based on the electromagnetic force in externally generated magnetic fields. Characteristics of SEMAs are their high stretchability, large deformation, fast response and low-voltage actuation. Here, vibration applications of the soft actuators can be utilised in vibration experiments involving flexible structures with curved surfaces and in wearable devices such as haptic displays. The low actuation voltage of the SEMA can make these applications safer for humans. To develop novel SEMA vibration devices, their fundamental performance should be evaluated by performing vibration experiments for simple mechanical structures. First, the proposed SEMA is fabricated by combining a soft substrate made of silicone material and a stretchable coil made of liquid metal. A permanent magnet is used to generate an electromagnetic force. For the SEMA to obtain a larger electromagnetic force, two different permanent magnet configurations are tested by varying their location and orientation. Second, to estimate the distribution of the SEMA electromagnetic force, a finite-element method (FEM)-based simulation is performed. In the vibration experiment system, the SEMA is attached directly to the simple rigid cantilever beam using adhesive tape.

Such bio-inspiration is essential for developing future flapping wing micro air vehicles (FWMAVs) that combine advanced maneuverability with design simplicity, low weight, and high power efficiency. In this work, we propose a novel unibody with distributed compliant joints inspired by the multiple degrees of actuation freedom of an insect thorax-in particular, wing stroke plane modulation for active pitch and yaw-yielding a compact multifunctional structural component for the 24.6&#x2009;g FWMAV: Delfly Flex . All of these functions are achieved within a single 3.73&#x2009;g 3D-printed integrated airframe. To design this unibody, we provide an analytical framework that guides compliant joint geometry using differential flexure beam analysis, along with an optimal joint orientation analysis for seamless integration into the unibody. To ensure sufficient structural endurance, we investigate various resin materials and printing configurations, resulting in a robust resin-printed unibody that incorporates two compliant joints and wing-root stabilizers. This single structure replaces the conventional multi-component FWMAV body composed of rigid-hinge-based dihedral pitch &amp; yaw mechanisms attached to a rod-like fuselage. We characterize the flight capabilities of Delfly Flex through tethered experiments measuring force and moment generation. The results show thrust generation and yaw moment arms equivalent to its predecessor, while the pitch moment arm is approximately 50% smaller due to the concentrated mass distribution inherent to the unibody design. Free-flight experiments further validate the concept, demonstrating controlled pitch and yaw maneuvers enabled by compliant beams as thin as 0.4&#x2009;mm. Combined with simplified assembly and more than 10% mass reduction, this unibody concept opens pathways toward future designs with increased deformability and expanded control authority.

Most reported designs feature bilayer architectures that respond to uniform moisture, or monolayered structures that rely on humidity gradients. However, achieving mechanical motion in monolayers under uniform moisture remains challenging. Here, we present a monolayered moisture-responsive actuator that bends mechanically upon uniform exposure to moisture or in water. The actuator is fabricated from branched polyethylenimine (BPEI) and polyethene glycol diacrylate (PEGDA) via an in situ copolymerization and casting-evaporation process. A coating of octadecyl acrylate (ODA) is applied covalently on one side of the gel to achieve the actuation. The resulting actuator exhibits an unidirectional bending response under uniform moisture conditions. The extent of bending was systematically studied by varying PEGDA content, hydrophobic coating type, and the temperature of the aqueous environment. Importantly, the actuation mechanism differs fundamentally from previously reported moisture-driven systems. Upon contact with water, surface amine groups undergo partial protonation, forming a dense hydrogen-bonded network involving amide groups, ammonium ions, free amines, and water molecules. This network induces surface shrinkage rather than swelling, thereby driving motion. The highest bending angle achieved is 140&#xb0;. The strategic covalent integration of hydrophilic and hydrophobic components imparts anisotropy to the monolayer, enabling excellent bending even under omnidirectional moisture exposure. Several proof-of-concept demonstrations, including biomimetic and soft-robotic applications, were conducted.

This study analyzes 1000 trajectories of flying honeybees in crowded conditions approaching a stimulus and finds a dominant flight coordination architecture of 'dyadic' interactions and a new three-zone decision-making process. The experiment measures individual insect positions via an optical tracking system recording honeybees returning to a robotically-actuated hive entrance. Neighborhood analysis through three methods (cross-correlation, distance threshold, and average distance threshold) reveals the dominant interaction is dyadic, consisting of transient leader-follower behaviors embedded in the larger collective. The followers' update rules are then tested against three regulation candidates (control strategies by which the follower adjusts its motion: optic flow, relative velocity, and 'optical expansion rate') to minimize root mean square error. The results show that in each dyad, the follower proceeds through a three-stage process involving a change to feedback rules that is separated by an intermediate unregulated period. An insect initially maintains a consistent (less than 8% variation) optical expansion rate until the inter-agent distance is as small as 10&#x2009;cm. The regulation candidates then undergo large variations during an observation/decision zone lasting an average of 1.04&#x2009;s. 79% of followers entering the decision zone then re-engage to track the same initial leader while 21% disengage. Upon re-engagement, the follower regulates inter-agent relative velocity, consistent with a closed-loop feedback proportional-integral controller regulating velocity tracking error. Proportional gain showed low variability across individuals, while derivative gain was found negligible and integral gain varied by individual.

Recently, researchers have developed perching-capable aerial robots as a way to save energy, and deformable structures demonstrate significant advantages in efficiency of perching and compactness of configuration. However, ensuring flight stability remains challenging for deformable aerial robots due to the difficulty of controlling flexible arms. Furthermore, perching for human interaction requires high compliance along with safety. Thus, this study aims to develop a deformable aerial robot capable of perching on humans with high flexibility and grasping ability. To overcome the challenges of stability of both flight and perching, we propose a hybrid morphing structure that combines a unilateral flexible arm and pneumatic inflatable actuators. This design allows the robot's arms to remain rigid during flight and soft while perching for more effective grasping. We also develop a pneumatic control system that improves pressure regulation while integrating safe and compliant contact and adjustable grasping forces, enhancing interaction capabilities and reducing energy consumption. Besides, we focus on the structural characteristics of the unilateral flexible arm and identify sufficient conditions under which standard quadrotor modeling and control remain effective in terms of flight stability.

Perception latency, defined as the delay between visual sensing and steering actuation, can degrade lateral tracking performance and steering stability. While delay compensation has been extensively studied in classical predictive control systems, its treatment within vision-based imitation-learning architectures under constant and time-varying perception latency remains limited. Rather than reducing latency itself, PLM-Net mitigates its effect on control performance through a plug-in architecture that preserves the original control pipeline. The framework consists of a frozen Base Model (BM), representing an existing lane-keeping controller, and a Timed Action Prediction Model (TAPM), which predicts future steering actions corresponding to discrete latency conditions. Real-time mitigation is achieved by interpolating between model outputs according to the measured latency value, enabling adaptation to both constant and time-varying latency. The framework is evaluated in a closed-loop deterministic simulation environment under fixed-speed conditions to isolate the impact of perception latency. Results demonstrate significant reductions in steering error under multiple latency settings, achieving up to 62% and 78% reductions in Mean Absolute Error (MAE) for constant and time-varying latency cases, respectively.

We demonstrate that this minimal design integrates mechanical feedback between activity and shape, resulting in a rich array of modes of motion-including railway and undulatory locomotion, rotation, and beating. It furthermore gives rise to emergent sense-response abilities, which enable autonomous reorientation, navigation, and collision avoidance. Our approach offers a versatile platform for designing biomimetic model systems and autonomously operating microrobots with embodied intelligence.","url":"https://pubmed.ncbi.nlm.nih.gov/41886376/","authors":["Wei M","Kraft DJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Mar 31","doi":"10.1073/pnas.2531743123","addedAt":"2026-08-31T06:34:19.810Z","updatedAt":"2026-08-31T06:34:19.810Z"},{"id":"pmid:41885057","name":"3D-Printed Dynamic Liquid Crystal Elastomer Composites with Adaptive Reconfiguration Showing Multimodal, Light-Driven, Strider-Inspired Locomotion at the Air-Water Interface.","source":"pubmed","abstract":"Inspired by the environment-adaptive behaviors of water striders, we 3D-printed a light-driven liquid crystal elastomer (LCE) swimming robot, OptiLCE Strider, capable of multimodal locomotion and adaptive reconfiguration at the air-water interface.

Although model-based control forms the foundation of high-performance robotics, real-world deployment is often hindered by model uncertainty, time-varying dynamics, and costly identification. As a result, low-order and intuitive control schemes remain dominant, yet such approaches often fail to sustain consistent performance under disturbances and parameter variations. Robust and adaptive control provide representative paradigms to address this gap, where a Disturbance Observer (DOB) suppresses uncertainty through disturbance rejection and a Parameter Adaptation Algorithm (PAA) improves model fidelity through online identification. However, direct integration of a DOB and a PAA often introduces functional interference, including mutual masking between disturbance compensation and parameter estimation, which compromises closed-loop stability. This paper proposes an Adaptive Disturbance Observer (ADOB) that integrates a DOB with online parameter adaptation. The ADOB updates the nominal model of the DOB in real time using a Recursive Least Squares (RLS)-based PAA, while a dual-filtering structure separates disturbance rejection and parameter identification. Stability is analyzed using hyperstability theory, where a smoothing mechanism enforces the slowly varying parameter assumption.

The microrobots are incorporated into spheroids in a reliable manner, relying on cell-driven self-assembly. Locomotion of the microrobot-integrated spheroids is achieved by regulating the laser power (11.7-17.6 mW) and frequency (0.33 Hz), which leads to three characteristic modes of motion: jumping, vectoring, and pulling. The combination of these motions enables robust spheroid assembly with excellent biocompatibility. The system allows for the generation of complex tissue models, where fibrosarcoma (HT1080 cells) spheroids and healthy fibroblast (HDF cells) spheroids are assembled separately and then brought together using the microrobotic locomotion capabilities. The fusion of assembled HT1080 and HDF spheroids reveals cancer-stromal cell interactions and tissue integration, while a cancer-spheroid-centered radial arrangement of fibroblast spheroids demonstrates the construction of spatially sophisticated assembloids.

Light is a particularly attractive trigger for contactless stimulation of hydrogels that can induce reversible morphological changes without damaging the fragile gels. To meet the varied needs of applications in microfluidics, soft robotics, biomedicine, and other fields, there is significant demand for novel valve designs that are highly tunable, miniaturizable, and respond quickly to stimuli while maintaining their function over many activation cycles. Additionally, it is crucial to develop a more quantitative understanding of the mechanics of valve operation in response to different stimuli, especially when active hydrogels are combined with other materials in multicomponent devices. Here, stimulus-responsive valves are fabricated using active hydrogels deformed upon temperature changes and exposure to near-infrared radiation. Gold nanorods (AuNRs) acting as photothermal transducers are embedded inside cross-linked poly N -isopropylacrylamide (PNIPAM), allowing local morphological changes in response to light with high spatiotemporal control. These changes are described precisely as a function of the valve's confinement, aspect ratio, and the parameters of the stimulus using quantitative image analysis, providing novel mechanistic insights. Changing the aspect ratio of the valves and the degree of confinement of the hydrogel causes valves to either open or close during heating and can be used to control the magnitude of their response to different stimuli. These varied morphological changes are due to local, inhomogeneous deformations of the gel. The use of light as a trigger enables local confinement of the valve, reversible opening and closing, and fast response times on the order of seconds. The valves are shown to withstand hydrostatic pressures of up to 18 kPa, providing high potential for biomedical applications where precise pressure control and quick switching between open and closed states is critical.","url":"https://pubmed.ncbi.nlm.nih.gov/41730707/","authors":["Mittelholzer A","Hickl V","Maniura-Weber K","Boesel LF","Rossi RM","Rottmar M","Chandorkar Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Mar 10","doi":"10.1021/acs.langmuir.5c05520","addedAt":"2026-08-31T06:34:19.810Z","updatedAt":"2026-08-31T06:34:19.810Z"},{"id":"pmid:41730082","name":"Molecular Semiconductor-Induced Deep Trapping Enables Ultrahigh-Performance Dielectric Elastomers.","source":"pubmed","abstract":"Dielectric elastomer actuators are ideal drivers for next-generation soft robots due to their large electroactive deformations.

Four types of actuators, containing up to 0.5 wt % CNTs, were studied for their light-responsivity. While CNTs had only a modest effect on mechanical properties, their impact on optical absorption was pronounced, producing a linear increase with concentration. Consequently, CNTs-containing actuators reached temperatures nearly 3-fold higher than CNTs-free counterparts, enabling up to 3-fold larger and faster motions during irradiation heating and beam obscuration cooling. Consecutive heating-cooling cycles revealed a secondary shape-change mechanism, previously unreported for this material system, arising from the coefficient of moisture expansion (CME) mismatch between the polyPOSS and Kapton layers. This CME-based mechanism operates independently of CNTs presence and competes with the primary coefficient of thermal expansion (CTE)-based mechanism. During initial heating, desorption of yet-absorbed moisture from the polyPOSS drives contraction, while thermal expansion promotes elongation, with dominance shifting from CTE- to CME- and back to CTE-based responses across the heating range.

The current study focuses on developing actuators with improved porosity by creating constructs based on LCNs hybridized with liquid crystal hydrogels (LCHs).

To overcome the limitations of existing thermally drawn fiber-based actuator systems, this study presents the development of all-polymer soft actuator fibers based on dielectric elastomers, designed to provide enhanced mechanical compliance and increased actuation freedom. A thermoplastic polyurethane (PU) elastomer was selected as the primary material due to its compatibility with the thermal drawing process and its electroactive response under applied electric fields. The resulting dielectric elastomer actuator (DEA) fibers exhibit intrinsic softness, with an overall Young's modulus of 37 MPa, enabling electrically controllable actuation modes with high freedom in bending, compression, and three-dimensional-(3D) swirling motions. An estimated compression strain of 1.59% was achieved at a driving frequency of 1 Hz and an electrical field of 2.4 MV/m, which is consistent with literature-reported values.

This approach circumvents the limitations of traditional negative-pressure adhesion mechanisms at microscales, offering a novel paradigm for integrating actuation and motion control in miniature wall-climbing robots. The strategy significantly expands the application scope of wall-climbing robots in biomedical scenarios, such as targeted drug delivery and minimally invasive surgery, while providing insights for designing multifunctional microrobots with adaptive locomotion capabilities.","url":"https://pubmed.ncbi.nlm.nih.gov/41619423/","authors":["Yue H","Chang X","Zhou D","Li L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 May","doi":"10.1016/j.cis.2026.103789","addedAt":"2026-08-31T06:34:19.811Z","updatedAt":"2026-08-31T06:34:19.811Z"},{"id":"pmid:41608905","name":"Holographic Whole-Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators.","source":"pubmed","abstract":"Liquid crystalline (LC) crosslinked polymeric structures are promising for soft robotic applications, as their actuation profile is intrinsically encoded and results from the structure's shape and the LC molecular orientation (director).

Liquid crystalline molecules are commonly aligned using modified surfaces or electric/magnetic fields. However, additive manufacturing methods may locally distort the director, when fabricating 3D objects. Here, holographic microlithography is employed to form entire connected 3D objects in a single exposure by cross-linking the LC, while allowing the director orientation within the object to be freely controlled. This enables us to independently choose a global director orientation and then realize complex 3D geometries in a single fabrication step. This approach avoids the director distortion present in sequential 3D printing and lithography methods, and allows for complex actuation profiles that are directly linked to the 3D director orientation.

These edible devices include different components, such as sensors, actuators, and other electronic elements, all made from edible ingredients such as sugars, proteins, polysaccharides, polymers, and others. Among the different fabrication approaches, 3D printing can provide reliable solutions to specific requirements. The concept of EEs has the potential to transform healthcare, providing more convenient, less invasive alternatives and personalized, customizable products for patients that beat traditional manufacturing methods. While the potential is enormous, there are critical challenges, notably ensuring the long-term stability, and regulatory and safety of these devices within the human body. Accordingly, a detailed understanding of the underlying concepts, fabrication approaches, design considerations, and action in the body/application range has been presented. As an evolving field, there is ample scope for research and multiple challenges must be addressed; these are elaborated towards the concluding sections of this article.","url":"https://pubmed.ncbi.nlm.nih.gov/39752889/","authors":["Santhoshkumar P","Ramu D","Mahalakshmi L","Moses JA"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025 Mar 15","doi":"10.1016/j.bios.2024.117059","addedAt":"2026-08-31T06:34:19.861Z","updatedAt":"2026-08-31T06:34:19.861Z"},{"id":"pmid:41923864","name":"Biohybrid living robotics: A comprehensive review of recent advances, technological innovation, and future prospects.","source":"pubmed","abstract":"Biohybrid robotics combines living components with synthetic materials to create adaptable, responsive robots.

Over the last decades, many photomechanical organic crystals have been developed, commonly via photochemical reactions, particularly photoisomerization. However, photochemical crystal actuation is associated with several drawbacks, including a limited number of available crystals, slow actuation speed (&lt;5&#x2005;Hz), and narrow wavelength range (&lt;550&#x2005;nm). Such constraints have hindered the widespread use of crystals as actuation materials. In this minireview, we focus on crystal actuation by employing more universal physical phenomena (the photothermal effect and photothermally resonated natural vibration) and quantitatively evaluate actuation performance. Both mechanisms, particularly the latter, outperformed conventional photomechanical crystal activation in terms of both speed (maximum: 1,350&#x2005;Hz) and the useful wavelength range (ultraviolet to near-infrared). The oscillation frequencies of the crystals exceeded those of polymers, efficiently filling the gap between soft and hard materials. Both the photothermal effect and natural vibration can actuate any crystal that absorbs light. These two versatile physical actuation mechanisms could expand 40&#x2005;years of research on photomechanical crystals-which had been based on photochemical reactions-from the realm of chemistry into engineering and lead to their practical applications in actuators and soft robots.","url":"https://pubmed.ncbi.nlm.nih.gov/39400511/","authors":["Hasebe S","Hagiwara Y","Asahi T","Koshima H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025 Jan 2","doi":"10.1002/anie.202418570","addedAt":"2026-08-31T06:34:19.861Z","updatedAt":"2026-08-31T06:34:19.861Z"},{"id":"pmid:39392765","name":"Wearable and Implantable Soft Robots.","source":"pubmed","abstract":"Soft robotics presents innovative solutions across different scales.

The multifunctioning joints lead to a high degree of compactness which then leads to a host of benefits such as low mass, low moment of inertia and low drag. This paper presents three case studies of multifunctioning joints-the human wrist joint, knee joint and foot joints-in order to identify how multifunctioning is achieved and what lessons can be learned for robotics. It also reviews the multifunctioning nature of muscle which plays an important role in joint actuation. A key finding is that multifunctioning is achieved through various means: multiple degrees of freedom, multifunctioning parts, over-actuation and reconfiguration. In addition, multifunctioning is achieved through highly sophisticated layouts with high levels of integration and fine-tuning. Muscle also makes an important contribution to animal agility by performing multiple functions including providing shape, protection and heat. The paper reviews progress in achieving multifunctioning in robot joints particularly for the wrist, knee and foot.

This modeling shortcoming is essential to be addressed since customized SPAs are used in a variety of applications, each with different output requirements.","url":"https://pubmed.ncbi.nlm.nih.gov/39319196/","authors":["Moutousi M","Polygerinos P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1418484","addedAt":"2026-08-31T06:34:19.861Z","updatedAt":"2026-08-31T06:34:19.861Z"},{"id":"pmid:39206574","name":"Design and batch fabrication of anisotropic microparticles toward small-scale robots using microfluidics: recent advances.","source":"pubmed","abstract":"Small-scale robots with shape anisotropy have garnered significant scientific interest due to their enhanced mobility and precise control in recent years.

The capacity to interact with the environment is largely dependent on the ability to use both hands. A thorough review of the current state of the art reveals that commercially available prosthetic hands designed for children are very different in functionality from those developed for adults, primarily due to prosthetic hands for adults featuring a greater number of actuated joints. Many times, patients stop using their prosthetic device because they feel that it does not fit well in terms of shape and size. With the idea of solving these problems, the design of HandBot-Kid has been developed with the anthropomorphic qualities of a child between the ages of eight and twelve in mind. Fitting the features of this age range, the robotic hand has a length of 16 cm, width of 7 cm, thickness of 3.6 cm, and weight of 328 g. The prosthesis is equipped with a total of fifteen degrees of freedom (DOF), with three DOFs allocated to each finger. The concept of design for manufacturing and assembly (DFMA) has been integrated into the development process, enabling the number of parts to be optimized in order to reduce the production time and cost. The utilization of 3D printing technology in conjunction with aluminum machining enabled the manufacturing process of the robotic hand prototype to be streamlined. The flexion-extension movement of each finger exhibits a trajectory that is highly similar to that of a real human finger. The four-bar mechanism integrated into the finger design achieves a mechanical advantage (MA) of 40.33% and a fingertip pressure force of 10.23 N.

The vertebrate limb pattern (e.g. shoulder, elbow, wrist and digits) has been proven to be very successful in many different applications in the animal kingdom. However, the actual level of optimality of the limb for each animal application is not clear because for some cases (e.g. whale flippers and bird wings), the basic skeletal layout is assumed to be highly constrained by evolutionary ancestry. This paper addresses this important and fundamental question of optimality by analysing six limbs with contrasting functions: human arm, whale flipper, bird wing, human leg, feline hindlimb and frog hindlimb. A central finding of this study is that the vertebrate limb pattern is highly versatile and optimal not just for arms and legs but also for flippers and wings. One key design feature of the vertebrate limb pattern is that of networks of segmented bones that enable smooth morphing of shapes as well as multifunctioning structures. Another key design feature is that of linkage mechanisms that fine-tune motions and mechanical advantage. A total of 52 biomechanical design features of the vertebrate limb are identified and tabulated for these applications. These tables can be a helpful reference for designers of bioinspired robotic and prosthetic limbs.

In this review, after an up-to-date account of present knowledge of the structural, physiological and molecular adaptations of MCT and the mechanisms responsible for its variable tensile properties, we focus on MCT as a concept generator surveying biomimetic systems inspired by MCT biology, showing that these include both bio-derived developments (same function, analogous operating principles) and technology-derived developments (same function, different operating principles), and suggest a strategy for the further exploitation of this promising biological resource.","url":"https://pubmed.ncbi.nlm.nih.gov/38248662/","authors":["Candia Carnevali MD","Sugni M","Bonasoro F","Wilkie IC"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Jan 7","doi":"10.3390/md22010037","addedAt":"2026-08-31T06:34:19.861Z","updatedAt":"2026-08-31T06:34:19.861Z"},{"id":"pmid:38239102","name":"Lipid vesicle-based molecular robots.","source":"pubmed","abstract":"A molecular robot, which is a system comprised of one or more molecular machines and computers, can execute sophisticated tasks in many fields that span from nanomedicine to green nanotechnology.

Most state-of-the-art robotic structures required for visual, tactile, or vestibular perception outperform human structures at the cost of slightly higher mass and volume. Electromagnetic and fluidic actuation outperform human muscles w.r.t. speed, endurance, force density, and power density, excluding components for energy storage and conversion.

Robots are capable of obstacle negotiation, object manipulation, swimming, playing soccer, or vehicle operation. Despite the impressive advances of humanoid robots in the last two decades, current robots are not yet reaching the dexterity and versatility to cope with more complex manipulation and locomotion tasks (e.g., in confined spaces). We conclude that state-of-the-art humanoid robotics is far from matching the dexterity and versatility of human beings.

However, in the past, they have not been able to reach their full potential due to limitations in wing control and payload capacity, which also has limited endurance. Many previous FWAVs used a single actuator that couples and synchronizes motions of the wings to flap both wings, resulting in only variable rate flapping control at a constant amplitude. Independent wing control is achieved using two servo actuators that enable wing motions for FWAVs by programming positions and velocities to achieve desired wing shapes and associated aerodynamic forces. However, having two actuators integrated into the flying platform significantly increases its weight and makes it more challenging to achieve flight than a single actuator. This article presents a retrospective overview of five different designs from the \"Robo Raven\" family based on our previously published work. The first FWAVs utilize two servo motors to achieve independent wing control. The basic platform is capable of successfully performing dives, flips, and button hook turns, which demonstrates the potential maneuverability afforded by the independently actuated and controlled wings. Subsequent designs in the Robo Raven family were able to use multifunctional wings to harvest solar energy to overcome limitations on endurance, use on-board decision-making capabilities to perform maneuvers autonomously, and use mixed-mode propulsion to increase payload capacity by exploiting the benefits of fixed and flapping wing flight. This article elucidates how each successive version of the Robo Raven platform built upon the findings from previous generations. The Robo Raven family collectively addresses requirements related to control autonomy, energy autonomy, and maneuverability.

The COVID-19 pandemic has exacerbated the existing lack of access to rehabilitation for stroke survivors post-discharge. Home-based stroke rehabilitation devices could improve access to rehabilitation for stroke survivors, but the home environment presents unique challenges compared to clinics. The present study undertakes a scoping review of designs for at-home upper limb stroke rehabilitation mechatronic devices to identify important design principles and areas for improvement. Online databases were used to identify papers published 2010-2021 describing novel rehabilitation device designs, from which 59 publications were selected describing 38 unique designs. The devices were categorized and listed according to their target anatomy, possible therapy tasks, structure, and features. Twenty-two devices targeted proximal (shoulder and elbow) anatomy, 13 targeted distal (wrist and hand) anatomy, and three targeted the whole arm and hand. Devices with a greater number of actuators in the design were more expensive, with a small number of devices using a mix of actuated and unactuated degrees of freedom to target more complex anatomy while reducing the cost. Twenty-six of the device designs did not specify their target users' function or impairment, nor did they specify a target therapy activity, task, or exercise. Twenty-three of the devices were capable of reaching tasks, 6 of which included grasping capabilities. Compliant structures were the most common approach of including safety features in the design. Only three devices were designed to detect compensation, or undesirable posture, during therapy activities. Six of the 38 device designs mention consulting stakeholders during the design process, only two of which consulted patients specifically. Without stakeholder involvement, these designs risk being disconnected from user needs and rehabilitation best practices. Devices that combine actuated and unactuated degrees of freedom allow a greater variety and complexity of tasks while not significantly increasing their cost.

Additionally, PLF contributes to optimizing the ability to manage and monitor animal welfare while providing solutions to global grand challenges posed by the growing demand for animal products and ensuring global food security. By enabling a return to the \"per animal\" approach by harnessing technological advancements, PLF enables cost-effective, individualized care for animals through enhanced monitoring and control capabilities within complex farming systems. Meeting the nutritional requirements of a global population exponentially approaching ten billion people will likely require the density of animal proteins for decades to come. The development and application of digital technologies are critical to facilitate the responsible and sustainable intensification of livestock production over the next several decades to maximize the potential benefits of PLF. Real-time continuous monitoring of each animal is expected to enable more precise and accurate tracking and management of health and well-being. Importantly, the digitalization of agriculture is expected to provide collateral benefits of ensuring auditability in value chains while assuaging concerns associated with labor shortages. Despite notable advances in PLF technology adoption, a number of critical concerns currently limit the viability of these state-of-the-art technologies. The potential benefits of PLF for livestock management systems which are enabled by autonomous continuous monitoring and environmental control can be rapidly enhanced through an Internet of Things approach to monitoring and (where appropriate) closed-loop management.

A total of six animal studies and eight human studies have been published. The animal studies refer to 123 experimental animals (68&#x2009;AD and 55 PD) and 121 wild-type animals, while the human studies refer to 142 patients with neurodegenerative disease (including 56&#x2009;AD and 17 PD) and 166 controls.

Most scholarly reviews of soft wearables have focused on the perspective of service providers such as developers, manufacturers, or clinicians, but few have scrutinized the factors affecting adoption and user experience. Hence, this would pose a good opportunity to gain insight into the current practice of soft robotics from a user's perspective. This review aims to provide a broad overview of the different types of soft wearables and identify the factors that hinder the adoption of soft robotics. In this paper, a systematic literature search using terms such as \"soft\", \"robot\", \"wearable\", and \"exoskeleton\" was conducted according to PRISMA guidelines to include peer-reviewed publications between 2012 and 2022. The soft robotics were classified according to their actuation mechanisms into motor-driven tendon cables, pneumatics, hydraulics, shape memory alloys, and polyvinyl chloride muscles, and their pros and cons were discussed. The identified factors affecting user adoption include design, availability of materials, durability, modeling and control, artificial intelligence augmentation, standardized evaluation criteria, public perception related to perceived utility, ease of use, and aesthetics. The critical areas for improvement and future research directions to increase adoption of soft wearables have also been highlighted.","url":"https://pubmed.ncbi.nlm.nih.gov/36991974/","authors":["Ang BWK","Yeow CH","Lim JH"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.3390/s23063263","addedAt":"2026-08-31T06:34:19.861Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"pmid:36971815","name":"User interfaces for actuated scope maneuvering in surgical systems: a scoping review.","source":"pubmed","abstract":"A variety of human computer interfaces are used by robotic surgical systems to control and actuate camera scopes during minimally invasive surgery.

The technological limitations of design optimization, choice of sensing, kinematic modeling, physical constraints, and real-time control had hampered early developments in this emerging field, but continued research and development in these areas over time has granted neurosurgeons far greater confidence in using cranial robotic techniques.

We are proposing a framework to accelerate the process and make the resulting exoskeletons more user-centered. The needed accomplishments in science are described in an effort to lay the foundation for future research projects. Since the early 2000s, exoskeletons have been discussed as an emerging technology in industrial, medical, or military applications. Those systems are designed to support people during manual tasks. At first, those systems lacked broad acceptance. Many models found their niches in ongoing developments and more diverse systems entering the market. There are still applications that are in dire need of such assistance. Due to the lack of experience with body-worn robotics, the development of such systems has been shaped by trial and error. The lack of legacy products results in longer development times. In this paper, a process to generate a framework is presented to display the required research to enable future exoskeleton designers. Owing to their proximity to the user's body, exoskeletons are highly complex systems that need sophisticated subsystems, such as kinematic, control, interaction design, or actuators, to be accepted by users. Due to the wide variety of fields and high user demands, a synchronized multidisciplinary effort is necessary. To achieve this, a process to develop a modular framework for exoskeleton design is proposed. It focuses on user- and use-case-centered solutions for matching kinematics, actuation, and control. To ensure the usefulness of the framework, an evaluation of the incorporated solutions is required.","url":"https://pubmed.ncbi.nlm.nih.gov/38487778/","authors":["Bengler K","Harbauer CM","Fleischer M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1017/wtc.2022.28","addedAt":"2026-08-31T06:34:19.861Z","updatedAt":"2026-08-31T06:34:19.861Z"},{"id":"pmid:36534488","name":"Microrobots for Targeted Delivery and Therapy in Digestive System.","source":"pubmed","abstract":"Untethered miniature robots enable targeted delivery and therapy deep inside the gastrointestinal tract in a minimally invasive manner.

Compared with conventional surgical tools, such as endoscopic devices and catheters, miniature robots feature minimally invasive diagnosis and treatment, multifunctionality, high safety and adaptivity, embodied intelligence, and easy access to tortuous and narrow lumens. In addition, the active motion of microrobots enhances local penetration and retention of drugs in tissues compared to common passive oral drug delivery. Based on the dissimilar microenvironments in the various sections of the gastrointestinal tract, this review introduces the advances of miniature robots for minimally invasive targeted delivery and therapy of diseases along the gastrointestinal tract.

This paper presents a critical review of state-of-the-art wearable sensing technologies that measure deeper muscle activity with high spatial resolution, so-called super-resolution. This paper classifies these myographic sensors according to the different signal types (i.e., biomechanical, biochemical, and bioelectrical) they record during measuring muscle activity. By describing the characteristics and current developments with advantages and limitations of each myographic sensor, their capabilities are investigated as a super-resolution myography technique, including: (i) non-invasive and high-density designs of the sensing units and their vulnerability to interferences, (ii) limit-of-detection to register the activity of deep muscles. Finally, this paper concludes with new opportunities in this fast-growing super-resolution myography field and proposes promising future research directions.

It was not just a vague question, as Prof. Wiersma, then the LENS director and leader of one of its research groups, already had an idea (and an ERC grant) about how to actually make such micro-robots, using a class of light-responsive oriented polymers, liquid crystal elastomers (LCEs), combined with the most advanced fabrication technique-two-photon 3D laser photolithography. Indeed, over the next few years, the LCE technology, successfully married with the so-called direct laser writing at LENS, resulted in a 60 micrometer long walker developed in Prof. Wiersma's group (as, surprisingly, walking at that stage proved to be easier than swimming).

Traditionally, compression has been done through under-sized (e.g. elastic) or size-adjustable (e.g. inflatable) compression garments. Such systems are designed to apply substantially uniform pressure on the body. However, due to reasons such as anatomical variations and body posture change, different levels of compression may be applied to the body. Further, a high level of discomfort and non-compliance is reported among patients due to donning difficulties. Therefore, there have been some efforts to make compression garments smart by employing advanced functional soft materials and actuators (such as Shape Memory Alloy (SMA), Shape Memory Polymer (SMP), Electroactive polymer (EAP), etc.) as well as soft force-pressure sensors so that the compression level could be controlled and regulated for each person or specific tasks. However, despite these advances, there are still challenges to accurately controlling the on-body compression level that are mainly due to the inherent characteristics of the soft actuators or sensors and the sophisticated human body conditions. In this paper, we will first investigate the soft actuators and sensors that have the potential to be used for on-body compression applications. Then, integrated soft sensing-actuation systems for interfacial compression purposes are studied. Finally, the challenges that might be associated with this work are introduced.","url":"https://pubmed.ncbi.nlm.nih.gov/36346855/","authors":["Golgouneh A","Dunne LE"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1109/RBME.2022.3220505","addedAt":"2026-08-31T06:34:24.578Z","updatedAt":"2026-08-31T06:34:24.578Z"},{"id":"pmid:36306544","name":"Effectiveness of robotic exoskeletons for improving gait in children with cerebral palsy: A systematic review.","source":"pubmed","abstract":"Robotic exoskeletons have been developed to assist locomotion and address gait abnormalities in children with cerebral palsy (CP).

Minimally invasive surgery allows for fewer complications as microdevices operate through small incisions or natural orifices. However, current minimally invasive tools typically have restricted maneuverability, accessibility, and positional control of microdevices. Thermomagnetic-responsive microgrippers are microscopic multi-fingered devices that respond to temperature changes due to the presence of thermal-responsive polymers. Polymeric devices, made of poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAM-AAc) and polypropylene fumarate (PPF), self-fold due to swelling and contracting of the hydrogel layer. In comparison, soft metallic devices feature a pre-stressed metal bilayer and polymer hinges that soften with increased temperature. Both types of microdevices can self-actuate when exposed to the elevated temperature of a cancerous tumor region, allowing for direct targeting for biopsies. Microgrippers can also be doped to become magnetically responsive, allowing for direction without tethers and the retrieval of microdevices containing excised tissue. The smaller size of stimuli-responsive microgrippers allows for their movement through hard-to-reach areas within the body and the successful extraction of intact cells, RNA and DNA.

Involving heterogeneity through material layout is a widely used strategy to generate internal mismatches in active morphing structures. Once triggered by external stimuli, the entire structure undergoes cooperative deformation by minimizing the potential energy. However, the intrinsic limitation of soft materials emerges when it comes to applications such as soft actuators or load-bearing structures that require fast response and large output force. Many researchers have explored the use of the structural principle of snap-through bistability as the morphing mechanisms. Bistable or multi-stable mechanical systems possess more than one local energy minimum and are capable of resting in any of these equilibrium states without external forces. The snap-through motion could overcome energy barriers to switch among these stable or metastable states with dramatically distinct geometries. Attributed to the energy storage and release mechanism, such snap-through transition is quite highly efficient, accompanied by fast response speed, large displacement magnitude, high manipulation strength, and moderate driving force. For example, the shape-morphing timescale of conventional hydrogel systems is usually tens of minutes, while the activation time of hydrogel actuators using the elastic snapping instability strategy can be reduced to below 1 s. By rationally embedding stimuli-responsive inclusions to offer the required trigger energy, various controllable snap-through actuations could be achieved.

We first introduce the currently established manufacturing methods (3D printing and photolithography). Then, according to their different working principles, we divide acoustics-actuated microrobots into three categories including bubble propulsion, sharp-edge propulsion, and in-situ microrotor. Next, we summarize their established applications from targeted drug delivery to microfluidics operation to microsurgery. Finally, we illustrate current challenges and future perspectives to guide research in this field. This work not only gives a comprehensive overview of the latest technology of acoustics-actuated microrobots, but also provides an in-depth understanding of acoustic actuation for inspiring the next generation of advanced robotic devices.","url":"https://pubmed.ncbi.nlm.nih.gov/35334771/","authors":["Xiao Y","Zhang J","Fang B","Zhao X","Hao N"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2022 Mar 20","doi":"10.3390/mi13030481","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:35321419","name":"A Robotic Test Rig for Performance Assessment of Prosthetic Joints.","source":"pubmed","abstract":"Movement within the human body is made possible by joints connecting two or more elements of the musculoskeletal system. Losing one or more of these connections can seriously limit mobility, which in turn can lead to depression and other mental issues. This is particularly pertinent due to a dramatic increase in the number of lower limb amputations resulting from trauma and diseases such as diabetes. The ideal prostheses should re-establish the functions and movement of the missing body part of the patient. As a result, the prosthetic solution has to be tested stringently to ensure effective and reliable usage. This paper elaborates on the development, features, and suitability of a testing rig that can evaluate the performance of prosthetic and robotic joints via cyclic dynamic loading on their complex movements. To establish the rig's validity, the knee joint was chosen as it provides both compound support and movement, making it one of the major joints within the human body, and an excellent subject to ensure the quality of the prosthesis. Within the rig system, a motorised lead-screw simulates the actuation provided by the hamstring-quadricep antagonist muscle pair and the flexion experienced by the joint. Loads and position are monitored by a load cell and proximity sensors respectively, ensuring the dynamics conform with the geometric model and gait analysis.

However, in recent years an alternative trend is being explored, where the control architecture can be simplified by harnessing the passive mechanical characteristics of the soft robotic system. This approach is named \"morphological control\", and it can be used to decrease the number of components (tubing, valves and regulators) required by the controller. In this paper, we demonstrate morphological control of bio-inspired asymmetric motions for systems of soft bending actuators that are interconnected with passive flow restrictors. We introduce bending actuators consisting out of a cylindrical latex balloon in a flexible PVC shell. By tuning the radii of the tube and the shell, we obtain a nonlinear relation between internal pressure and volume in the actuator with a peak and valley in pressure. Because of the nonlinear characteristics of the actuators, they can be assembled in a system with a single pressure input where they bend in a discrete, preprogrammed sequence. We design and analyze two such systems inspired by the asymmetric movements of biological cilia. The first replicates the swept area of individual cilia, having a different forward and backward stroke, and the second generates a travelling wave across an array of cilia.","url":"https://pubmed.ncbi.nlm.nih.gov/35047567/","authors":["Milana E","Van Raemdonck B","Casla AS","De Volder M","Reynaerts D","Gorissen B"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.3389/frobt.2021.788067","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:35038215","name":"Smart Film Actuators for Biomedical Applications.","source":"pubmed","abstract":"Taking inspiration from the extremely flexible motion abilities in natural organisms, soft actuators have emerged in the past few decades.

In addition, we explore these trade-offs in the context of the SmartSuit architecture, a hybrid spacesuit with a soft-robotic layer that, not only increases mobility with assistive actuators in the lower body, but it also applies some level of mechanical counterpressure (MCP). The additional MCP in hybrid spacesuits can be used to supplement the gas pressure (i.e., increasing the total spacesuit pressure), therefore reducing the risk of DCS (or reduce prebreathe time). Alternatively, the MCP can be used to reduce the gas pressure (i.e., maintaining the same total spacesuit pressure), therefore increasing mobility. Finally, we propose a variable pressure concept of operations for the SmartSuit spacesuit. Our framework quantifies critical spacesuit and habitat trade-offs for future planetary exploration and contributes to the assessment of human health and performance during future planetary EVAs.","url":"https://pubmed.ncbi.nlm.nih.gov/34782645/","authors":["Kluis L","Diaz-Artiles A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021 Nov 15","doi":"10.1038/s41526-021-00175-3","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:34746905","name":"Electro-responsive actuators based on graphene.","source":"pubmed","abstract":"Electro-responsive actuators (ERAs) hold great promise for cutting-edge applications in e-skins, soft robots, unmanned flight, and in vivo surgery devices due to the advantages of fast response, precise control, programmable deformation, and the ease of integration with control circuits.

Their shape-morphing properties can be used in various applications such as robotics, artificial muscles, and biomedical devices. To take advantage of the stimuli-responsive properties of the smart polymers in such applications, programming shape change precisely through a facile synthetic procedure is essential. Programmable shape-morphing is readily obtained in hydrogels and liquid crystal polymer networks, but shape programming of semicrystalline polymers usually relies on low-resolution mechanical deformation. In this paper, a semicrystalline shape-morphing polymer with a controlled shape programmability was developed via photopatterning crystal orientation using a spatially controlled photopolymerization technique. The semicrystalline polymer network forms aligned crystallites at the boundaries between dark and bright regions during photopolymerization using a projector, which introduces an anisotropic stimulus response in the films. The semicrystalline polymer films with photoaligned crystallites expand 9-15% in the direction perpendicular to the patterned lines when heated above the melting temperature. Furthermore, spatially patterning the crystal orientation enables the formation of various complex 3D structures including a helical coil, a coil with a handedness inversion, a cone, a saddle, and a twisting flower. Finally, the magnitude of the shape transformation was controlled by varying the polymerization temperatures, and the actuation temperature was tuned by changing the amount of crystallinity in the polymer films. The simplicity and ease of control of our approach to program complex 3D structures from 2D semicrystalline polymer films make it a promising system for the aforementioned applications.","url":"https://pubmed.ncbi.nlm.nih.gov/34723466/","authors":["Jang LK","Abdelrahman MK","Ware TH"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2022 May 25","doi":"10.1021/acsami.1c15630","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:34683300","name":"A Review of Microrobot's System: Towards System Integration for Autonomous Actuation In Vivo.","source":"pubmed","abstract":"Microrobots have received great attention due to their great potential in the biomedical field, and there has been extraordinary progress on them in many respects, making it possible to use them in vivo clinically.

Therefore, rehabilitation is essential to mitigate the adverse effects of the different causes of physical disabilities and improve independence and quality of life. In the last decade, robotic rehabilitation has shown the potential to augment traditional physical rehabilitation. However, to date, most robotic rehabilitation devices are designed for adult patients who differ in their needs compared to paediatric patients, limiting the devices' potential because the paediatric patients' needs are not adequately considered. With this in mind, the current work reviews the existing literature on robotic rehabilitation for children with physical disabilities, intending to summarise how the rehabilitation robots could fulfil children's needs and inspire researchers to develop new devices. A literature search was conducted utilising the Web of Science, PubMed and Scopus databases. Based on the inclusion-exclusion criteria, 206 publications were included, and 58 robotic devices used by children with a physical disability were identified. Different design factors and the treated conditions using robotic technology were compared. Through the analyses, it was identified that weight, safety, operability and motivation were crucial factors to the successful design of devices for children. The majority of the current devices were used for lower limb rehabilitation. Neurological disorders, in particular cerebral palsy, were the most common conditions for which devices were designed. By far, the most common actuator was the electric motor. Usually, the devices present more than one training strategy being the assistive strategy the most used. The admittance/impedance method is the most popular to interface the robot with the children. Currently, there is a trend on developing exoskeletons, as they can assist children with daily life activities outside of the rehabilitation setting, propitiating a wider adoption of the technology. With this shift in focus, it appears likely that new technologies to actuate the system (e.g. serial elastic actuators) and to detect the intention (e.g. physiological signals) of children as they go about their daily activities will be required.","url":"https://pubmed.ncbi.nlm.nih.gov/34488777/","authors":["Gonzalez A","Garcia L","Kilby J","McNair P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021 Sep 6","doi":"10.1186/s12938-021-00920-5","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:34485392","name":"Hardware Methods for Onboard Control of Fluidically Actuated Soft Robots.","source":"pubmed","abstract":"Soft robots provide significant advantages over their rigid counterparts. These compliant, dexterous devices can navigate delicate environments with ease without damage to themselves or their surroundings. With many degrees of freedom, a single soft robotic actuator can achieve configurations that would be very challenging to obtain when using a rigid linkage. Because of these qualities, soft robots are well suited for human interaction. While there are many types of soft robot actuation, the most common type is fluidic actuation, where a pressurized fluid is used to inflate the device, causing bending or some other deformation. This affords advantages with regards to size, ease of manufacturing, and power delivery, but can pose issues when it comes to controlling the robot. Any device capable of complex tasks such as navigation requires multiple actuators working together. Traditionally, these have each required their own mechanism outside of the robot to control the pressure within. Beyond the limitations on autonomy that such a benchtop controller induces, the tether of tubing connecting the robot to its controller can increase stiffness, reduce reaction speed, and hinder miniaturization. Recently, a variety of techniques have been used to integrate control hardware into soft fluidic robots. These methods are varied and draw from disciplines including microfluidics, digital logic, and material science. In this review paper, we discuss the state of the art of onboard control hardware for soft fluidic robots with an emphasis on novel valve designs, including an overview of the prevailing techniques, how they differ, and how they compare to each other. We also define metrics to guide our comparison and discussion. Since the uses for soft robots can be so varied, the control system for one robot may very likely be inappropriate for use in another.

Because balance and gait disorders may persist also in the chronic stage, reducing individual independence and participation, they represent primary goals of neurorehabilitation programs. For this purpose, in recent years, numerous technological devices have been developed, among which one of the most widespread is the Lokomat&#xae;, an actuated exoskeleton that guide the patient's limbs, simulating a symmetrical bilateral gait. Preliminary evidence suggests that beyond gait parameters, robotic assisted gait training may also improve balance. Therefore, the aim of this systematic review was to summarize evidence about the effectiveness of Lokomat&#xae; in improving balance in stroke patients. Methods: Randomized controlled trials published between January 1989 and August 2020, comparing Lokomat&#xae; training to conventional therapy for stroke patients, were retrieved from seven electronic databases. Balance, assessed by means of validated clinical scales, was considered as outcome measure. The Physiotherapy Evidence Database (PEDro) scale was used to evaluate the methodological quality of the studies. The study protocol was registered on PROSPERO (no. CRD42020197531). Results: After the removal of the duplicates, according to the inclusion criteria, 13 studies were selected, involving 445 subacute or chronic stroke patients. Eleven papers contributed to three meta-analyses. Favorable results for recovery of balance in stroke survivors treated with Lokomat&#xae; were shown using Timed Up and Go (pooled mean difference = -3.40, 95% CI -4.35 to -2.44; p &lt; 0.00001) and Rivermead Mobility Index as outcome measures (pooled mean difference = 0.40, 95% CI 0.26-0.55; p &lt; 0.00001). Inconclusive results were found when balance was measured by means of the Berg Balance Scale (pooled mean difference = 0.17, 95% CI -0.26 to 0.60; p = 0.44). Conclusions: Overall, most studies have shown beneficial effects of Lokomat&#xae; on balance recovery for stroke survivors, at least comparable to conventional physical therapy. However, due to the limited number of studies and their high heterogeneity, further research is needed to draw more solid and definitive conclusions.","url":"https://pubmed.ncbi.nlm.nih.gov/34295298/","authors":["Baronchelli F","Zucchella C","Serrao M","Intiso D","Bartolo M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.3389/fneur.2021.661815","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:34278252","name":"Paper-based wearable electronics.","source":"pubmed","abstract":"Skin-interfaced wearable electronics can find a broad spectrum of applications in healthcare, human-machine interface, robotics, and others.

Lower limb robot aided rehabilitation and assistive technology have been a focus for the engineering community during the last three decades as several robotic lower limb exoskeletons have been proposed in the literature as well as some being commercially available. Numerous manufacturing techniques and materials have been developed for lower limb exoskeletons during the last two decades, resulting in the design of a variety of robot exoskeletons for gait assistance for elderly and disabled people. One of the most important aspects of developing exoskeletons is the selection of the most appropriate proper material. The material selection strongly influences the overall weight and performance of the exoskeleton robot. The most suitable fabrication method for material is also an important parameter for the development of lower limb robot exoskeletons. In addition to the materials and manufacturing methods, the actuation method plays a vital role in the development of these robot exoskeletons. Even though various materials, manufacturing methods and actuators are reported in the literature for these lower limb robot exoskeletons, there are still avenues of improvement in these three domains.

Now, by leveraging magnetic nanoparticles, investigators have developed a range of modern applications that use external magnetic fields to manipulate biological systems. Drug delivery systems that incorporate these particles can target therapeutics to specific tissues without the need for biological or chemical cues. Once precisely located within an organism, magnetic nanoparticles can be heated by oscillating magnetic fields, which results in localized inductive heating that can be used for thermal ablation or more subtle cellular manipulation. Biological imaging can also be improved using magnetic nanoparticles as contrast agents; several types of iron oxide nanoparticles are US Food and Drug Administration (FDA)-approved for use in magnetic resonance imaging (MRI) as contrast agents that can improve image resolution and information content. New imaging modalities, such as magnetic particle imaging (MPI), directly detect magnetic nanoparticles within organisms, allowing for background-free imaging of magnetic particle transport and collection. \"Lab-on-a-chip\" technology benefits from the increased control that magnetic nanoparticles provide over separation, leading to improved cellular separation. Magnetic separation is also becoming important in next-generation immunoassays, in which particles are used to both increase sensitivity and enable multiple analyte detection.

Different morphologies and grasping methods of \"grippers\" are highly evolved to adapt to harsh survival conditions. For example, human hands and bird feet are composed of rigid frames and soft joints. Compared with human hands, some plants like Drosera do not have rigid frames, so they can bend at arbitrary points of the body to capture their prey. Furthermore, many muscular hydrostat animals and plant tendrils can implement more complex twisting motions in 3D space. Recently, inspired by the flexible grasping methods present in nature, increasingly more bio-inspired soft grippers have been fabricated with compliant and soft materials. Based on this, the present review focuses on the recent research progress of bio-inspired soft grippers based on impactive gripping. According to their types of movement and a classification model inspired by biological \"grippers\", soft grippers are classified into three types, namely, non-continuum bending-type grippers, continuum bending-type grippers, and continuum twisting-type grippers. An exhaustive and updated analysis of each type of gripper is provided.

Electromyography (EMG) can be used to carry out the neuromuscular characterization, but it is cumbersome because of the complexity of the musculoskeletal system of the forearm and hand. This paper reviews the main studies in which EMG has been applied to characterize the muscle activity of the forearm and hand during activities of daily living, with special attention to muscle synergies, which are thought to be used by the nervous system to simplify the control of the numerous muscles by actuating them in task-relevant subgroups.

Linkage mechanisms enable animal joints to perform highly sophisticated and optimised motions. A key function of animal linkage mechanisms is the optimisation of actuator location and mechanical advantage. This is crucially important for animals where space is highly constrained. Many of the design features used by engineers in linkage mechanisms are seen in nature, such as short coupler links, extended bars, elastic energy storage and latch mechanisms. However, animal joints contain some features rarely seen in engineering such as integrated cam and linkage mechanisms, nonplanar four-bar mechanisms, resonant hinges and highly redundant actuators. The extreme performance of animal joints together with the unusual design features makes them an important area of investigation for bioinspired designs.

Recently, this form of movement has been artificially realized through pressure-driven eversion of flexible, thin-walled tubes. Here we review recent work on robots that \"grow\" via pressure-driven eversion, referred to as \"everting vine robots,\" due to a movement pattern that is similar to that of natural vines. We break this work into four categories. First, we examine the design of everting vine robots, highlighting tradeoffs in material selection, actuation methods, and placement of sensors and tools. These tradeoffs have led to application-specific implementations. Second, we describe the state of and need for modeling everting vine robots. Quasi-static models of growth and retraction and kinematic and force-balance models of steering and environment interaction have been developed that use simplifying assumptions and limit the involved degrees of freedom. Third, we report on everting vine robot control and planning techniques that have been developed to move the robot tip to a target, using a variety of modalities to provide reference inputs to the robot. Fourth, we highlight the benefits and challenges of using this paradigm of movement for various applications. Everting vine robot applications to date include deploying and reconfiguring structures, navigating confined spaces, and applying forces on the environment. We conclude by identifying gaps in the state of the art and discussing opportunities for future research to advance everting vine robots and their usefulness in the field.","url":"https://pubmed.ncbi.nlm.nih.gov/33501315/","authors":["Blumenschein LH","Coad MM","Haggerty DA","Okamura AM","Hawkes EW"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.3389/frobt.2020.548266","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:33501271","name":"Internet of Robotic Things Intelligent Connectivity and Platforms.","source":"pubmed","abstract":"The Internet of Things (IoT) and Industrial IoT (IIoT) have developed rapidly in the past few years, as both the Internet and \"things\" have evolved significantly. \"Things\" now range from simple Radio Frequency Identification (RFID) devices to smart wireless sensors, intelligent wireless sensors and actuators, robotic things, and autonomous vehicles operating in consumer, business, and industrial environments. The emergence of \"intelligent things\" (static or mobile) in collaborative autonomous fleets requires new architectures, connectivity paradigms, trustworthiness frameworks, and platforms for the integration of applications across different business and industrial domains. These new applications accelerate the development of autonomous system design paradigms and the proliferation of the Internet of Robotic Things (IoRT). In IoRT, collaborative robotic things can communicate with other things, learn autonomously, interact safely with the environment, humans and other things, and gain qualities like self-maintenance, self-awareness, self-healing, and fail-operational behavior. IoRT applications can make use of the individual, collaborative, and collective intelligence of robotic things, as well as information from the infrastructure and operating context to plan, implement and accomplish tasks under different environmental conditions and uncertainties. The continuous, real-time interaction with the environment makes perception, location, communication, cognition, computation, connectivity, propulsion, and integration of federated IoRT and digital platforms important components of new-generation IoRT applications. This paper reviews the taxonomy of the IoRT, emphasizing the IoRT intelligent connectivity, architectures, interoperability, and trustworthiness framework, and surveys the technologies that enable the application of the IoRT across different domains to perform missions more efficiently, productively, and completely.

OSF are directly correlated with increasing age and incidence of osteoporosis. OSF are treated conservatively or surgically. Associated acute pain, chronic disabilities, and progressive deformities are well documented. Conservative measures include a combination of initial bed rest, analgesia, early physiotherapy, and a spinal brace (orthosis), with the aim for early rehabilitation to prevent complications of immobile state. Spinal bracing is commonly used for symptomatic management of OSF. While traditional spinal braces aim to maintain the neutral spinal alignment and reduce the axial loading on the fractured vertebrae, they are well known for complications including discomfort with reduced compliance, atrophy of paraspinal muscles, and restriction of chest expansion leading to chest infections. Exoskeletons have been developed to passively assist and actively augment human movements with different types of actuators. Flexible, versatile spinal exoskeletons are designed to better support the spine. As new technologies enable the development of motorized wearable exoskeletons, several types have been introduced into the medical field application. We have provided a thorough review of the current spinal robotic technologies in this paper. The shortcomings in the current spinal exoskeletons were identified. Their limitations on the use for patients with OSF with potential improvement strategies were discussed. With our current knowledge of spinal orthosis for conservatively managed OSF, a semi-rigid backpack style thoracolumbar spinal robotic orthosis will reduce spinal bone stress and improve back muscle support. This will lead to back pain reduction, improved posture, and overall mobility. Early mobilization is an important part of management of patients with OSF as it reduces the chance of developing complications related to their immobile state for patients with OSF, which will be helpful for their recovery.","url":"https://pubmed.ncbi.nlm.nih.gov/33451142/","authors":["Mak SKD","Accoto D"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021 Jan 13","doi":"10.3390/healthcare9010070","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:33420838","name":"Biomimetic soft micro-swimmers: from actuation mechanisms to applications.","source":"pubmed","abstract":"Underwater robot designs inspired by the behavior and morphological characteristics of aquatic animals can provide reinforced mobility and energy efficiency.

While synthetic systems, such as pneumatics and shape memory alloys, have created important breakthroughs in soft actuation, they typically rely on large external power sources and some rigid components. Muscles provide an ideal actuator for soft constructs, as they are lightweight, deformable, biodegradable, silent, and powered by energy-dense hydrocarbons such as glucose. Vertebrate cell lines and embryonic cultures have allowed critical foundational work to this end, but progress there is limited by the difficulty of identifying individual pathways in embryonic development, and the divergence of immortal cell lines from these normal developmental programs. An alternative to culturing muscles from embryonic cells is to exploit the advantages of species with metamorphic stages. In these animals, muscles develop from a predefined pool of myoblasts with well-characterized contacts to other tissues. In addition, the endocrine triggers for development into adult muscles are often known and tractable for experimental manipulation. This is particularly true for metamorphic muscle development in holometabolous insects, which provide exciting new avenues for tissue engineering. Using insect tissues for actuator development confers additional benefits; insect muscles are more robust to varying pH, temperature, and oxygenation than are vertebrate cells. Given that biohybrid robots are likely to be used in ambient conditions and changing environments, this sort of hardiness is likely to be required for practical use. In this study, we summarize key processes and signals in metamorphic muscle development, drawing attention to those pathways that offer entry points for manipulation. By focusing on lessons learned from in vivo insect development, we propose that future culture designs will be able to use more systematic, hypothesis-driven approaches to optimizing engineered muscle. Impact statement This review summarizes our current understanding of metamorphic muscle development in insects. It provides a framework for engineering muscle-based actuators that can be used in robotic applications in a wide range of ambient conditions. The focus is on identifying key processes that might be manipulated to solve current challenges in controlling tissue development such as myoblast proliferation, myotube formation and fusion, cytoskeletal alignment, myotendinous attachment and full differentiation. An important goal is to gather findings that cross disciplinary boundaries and to promote the development of better bioactuators for nonclinical applications.","url":"https://pubmed.ncbi.nlm.nih.gov/33012237/","authors":["Ludwig JC","Trimmer BA"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021 Aug","doi":"10.1089/ten.TEB.2020.0204","addedAt":"2026-08-31T06:34:24.579Z","updatedAt":"2026-08-31T06:34:24.579Z"},{"id":"pmid:33010474","name":"Mimicking nature's flyers: a review of insect-inspired flying robots.","source":"pubmed","abstract":"Insects have attracted much interest from scientists and engineers as they offer an endless source of inspiration for creating innovative engineering designs.

AND DEVELOPMENT OF A LEAD SCREW GRIPPER FOR ROBOTIC APPLICATION","source":"crossref","abstract":"This paper gives details on the electromechanical design concept and prototype development of a lead screw linear actuated, parallel robotic gripper. Robotic applications are known to be catering to many industries from a range of tasks namely pick &amp;amp; place, material handling, as fixtures, tool &amp;amp; instrument holders etc. These application specific robots are equipped with end effectors customised with design appropriate for the application. In this paper, presented are the details for the design of an end effector also known as the gripper which works on a lead screw linear mechanism actuated by a dc motor. The gripper of stroke 100 mm is designed to hold bottles, tools or pick and place objects of rectangular section of 90mm x 90mm or of circular section of 90mm diameter and up to 3kg weight. Mechanical assembly comprises a sheet metal fixture plate holding the actuating components and a sheet metal gripper plate performing the gripping action. The motor is driven by a 24V, 2A dc motor driver. The gripping action is sensed and signalled by a force sensitive resistor. Prototype development of the gripper and on/off testing for the gripping action is investigated. The mechanical construction for this unique lead screw gripper is observed to be robust and can be used as an end effector to a suitable robotic arm.","url":"https://doi.org/10.2139/ssrn.4882910","authors":["Krithikanand Krishnamoorthy"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-10T15:34:29Z","doi":"10.2139/ssrn.4882910","addedAt":"2026-08-31T06:34:26.466Z","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1021/acsapm.6c00858.s006","name":"Natural Rubber-Based Soft Robotic Gripper with Tunable Performance","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsapm.6c00858.s006","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-29T16:00:46Z","doi":"10.1021/acsapm.6c00858.s006","addedAt":"2026-08-31T06:34:26.466Z","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1021/acsapm.6c00858.s004","name":"Natural Rubber-Based Soft Robotic Gripper with Tunable Performance","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsapm.6c00858.s004","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-29T16:00:46Z","doi":"10.1021/acsapm.6c00858.s004","addedAt":"2026-08-31T06:34:26.466Z","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.1109/access.2025.3538001","name":"Motor-Less Robotic Gripper: Driving Mechanism by Robotic Manipulator Movement","source":"crossref","abstract":"","url":"https://doi.org/10.1109/access.2025.3538001","authors":["Toshihiro Nishimura","Kosei Ueno","Tetsuyou Watanabe"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-03T18:29:08Z","doi":"10.1109/access.2025.3538001","addedAt":"2026-08-31T06:34:26.466Z","updatedAt":"2026-08-31T06:34:34.731Z"},{"id":"doi:10.1021/acsapm.6c00858.s001","name":"Natural Rubber-Based Soft Robotic Gripper with Tunable Performance","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsapm.6c00858.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-29T16:00:46Z","doi":"10.1021/acsapm.6c00858.s001","addedAt":"2026-08-31T06:34:26.466Z","updatedAt":"2026-08-31T06:34:34.730Z"},{"id":"doi:10.2139/ssrn.4349188","name":"Aruco Marker-Based Pick and Place Approach Using a Ur5 Robotic Arm and Vacuum Gripper","source":"crossref","abstract":"With the advent of technology in this digital era, demand for a more optimized and cost-effective information storing source/algorithm is increasing which can also be used for other industrial application like pose estimation and navigation (especially indoor navigation – in homes, warehouses, offices, etc).

highly sensitive, hydrated, and relatively thin tissues, making precise control and accurate force estimation crucial in robotic eye surgery. This paper introduces a novel control method and state observer designed for a gripper surgical instrument used on the external ocular surface during robotic eye surgery. Methods A novel state observer, operating in tandem with the controller, estimates the applied force. The proposed control approach, termed the Fixed‐time Observer‐based Sliding Mode Control (FOSMC), estimates the applied force by determining the gripper states and uses an eye model to calculate its displacement. Results The performance of the proposed control method was compared with two other finite‐time and asymptotic techniques across two scenarios. The results demonstrated excellent performance using the proposed method. Conclusions The FOSMC control technique effectively estimates the applied force during robotic eye surgery, making it a reliable solution for controlling the gripper surgical instrument.","url":"https://doi.org/10.1002/rcs.70038","authors":["Ali Soltani Sharif Abadi","Andrew Ordys","Barbara Pierscionek"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/rcs.70038","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1016/j.ifacol.2025.12.257","name":"An Extended Generalized Prandtl-Ishlinskii Hysteresis Model for I&lt;sup&gt;2&lt;/sup&gt;RIS Robot.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.ifacol.2025.12.257","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1016/j.ifacol.2025.12.257","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:44.263Z"},{"id":"doi:10.3390/s25175430","name":"Deformable and Fragile Object Manipulation: A Review and Prospects.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25175430","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25175430","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1039/d5sc06192j","name":"Fully automated and high-fidelity robotic platform enabling accelerated discovery of nanocatalysts.","source":"europepmc","abstract":"","url":"https://doi.org/10.1039/d5sc06192j","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1039/d5sc06192j","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1016/j.wasman.2025.115123","name":"Enhancing sorting efficiency in cluttered construction and demolition waste streams via boundary-guided grasp detection.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.wasman.2025.115123","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1016/j.wasman.2025.115123","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:31.460Z"},{"id":"doi:10.1089/soro.2024.0166","name":"Origami-Based Flexible Robotic Grippers via Hard-Soft Coupled Multimaterial 3D Printing.","source":"europepmc","abstract":"This study explores the design and performance of origami robotic grippers fabricated through hard-soft coupled multimaterial three-dimensional (3D) printing. We evaluate the impact of design parameters on the kinematic behavior and mechanical functionality of the gripper. A kinematic model is employed to characterize the reachable workspace and motion capabilities, revealing that variations in geometric parameters significantly influence the origami gripper’s performance. Furthermore, we explore the mechanical properties of the gripper by manipulating parameters such as soft hinge thickness and crease design, establishing a comprehensive relationship between geometric design and mechanical response. Experimental evaluations demonstrate the interplay between bending angle, force–displacement characteristics, and stiffness in the origami grippers.

UAV payload technology (UPT) serves as a key support for enhancing mission performance and expanding application scenarios. UPT is being rapidly integrated into agriculture and other key fields, emerging as a driving force for the low-altitude economy and intelligent operations. This study systematically analyzed and discussed the development status of UPT, its typical application scenarios, and the challenges faced. By conducting a comprehensive review of global research on UPT from 2012 to 2025, this review summarized research hotspots and revealed evolutionary trends. The findings demonstrated that UPT had made notable progress in typical application areas, including crop monitoring, precision agricultural operations, agricultural product harvesting and aerial transportation, power line inspection, emergency rescue, and logistics. However, UPT was still constrained by limited autonomous perception and path planning capabilities, insufficient universality of payload platforms, a lack of standardized device interfaces, as well as challenges related to endurance, communication, and operational stability under adverse weather conditions. Future research should focus on lightweight and multifunctional payload design, intelligent operation control, and modular and standardized integration, while building a \"satellite-UAV-ground\" collaborative perception and decision-making system. The outcomes of this study provide both theoretical reference and practical guidance for promoting UAV adoption in agriculture and other low-altitude application scenarios, thereby contributing to the sustainable development of smart agriculture and the low-altitude economy.","url":"https://doi.org/10.3389/fpls.2025.1721484","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/fpls.2025.1721484","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.34133/research.0933","name":"Highly Stretchable and Reliable Graphene-Based Strain Sensor for Plant Health Monitoring and Deep Learning-Assisted Crop Recognition.","source":"europepmc","abstract":"Stretchable sensors hold great potential for monitoring plant physiological parameters and enabling crop identification in smart agriculture. However, achieving long-term, stable, reliable monitoring of plants in dynamic environments, as well as improving crop identification accuracy, remains a substantial challenge, primarily due to the limited biocompatibility of conventional stretchable sensors. Here, we present a highly stretchable and reliable strain sensor based on a graphene/Ecoflex composite. This sensor features a mesh structure that combines graphene's high electrical conductivity and strain sensitivity with Ecoflex's excellent stretchability, biocompatibility, and resistance to environmental degradation. By structural optimization, the sensor achieves high sensitivity (gauge factor = 138), a low detection limit (0.1% strain), and high reliability (over 1,500 cycles), along with waterproofing and resistance to both acidic and alkaline conditions. Furthermore, the sensor conforms tightly to various plant leaves and stems without hindering growth, enabling real-time monitoring of plant growth patterns and in situ detection of mechanical damage to predict plant stress. Moreover, assisted by deep learning, it precisely classifies 8 crop types with an accuracy of 95.2%. These demonstrate that stretchable sensors based on mesh graphene/Ecoflex can operate reliably in outdoor agricultural environments even in the face of variable climatic and chemical conditions, providing a practical platform for advancing plant phenomics and smart agricultural robotics.","url":"https://doi.org/10.34133/research.0933","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.34133/research.0933","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:31.460Z"},{"id":"doi:10.1080/17483107.2025.2547042","name":"Wheelchair-mounted robotic arms: a systematic review of technical design and activities of daily living outcomes.","source":"europepmc","abstract":"","url":"https://doi.org/10.1080/17483107.2025.2547042","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1080/17483107.2025.2547042","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1038/s41467-025-60779-1","name":"Cyborg insect factory: automatic assembly for insect-computer hybrid robot via vision-guided robotic arm manipulation of custom bipolar electrodes.","source":"europepmc","abstract":"Insect-computer hybrid robots offer strong potential for navigating complex terrains.

Researchers are trying to mimic nature in a more creative way so that the system can easily adapt to the complex nature and its environment. Hence, bio-robotic grippers play a role in the physical connection between the environment and the bio-robotics system. While handling the physical world using a bio-robotic gripper, complexity occurs in the feedback system, where the sensor plays a vital role. Therefore, a human-centered gripper sensor can have a good impact on the bio-robotics field. But categorical classification and the selection process are not very systematic. This review paper follows the PRISMA methodology to summarize the previous works on bio-robotic gripper sensors and their selection process. This paper discusses challenges in soft robotic systems, the importance of sensing systems in facilitating critical control mechanisms, along with their selection considerations. Furthermore, a classification of soft actuation based on grippers has been introduced. Moreover, some unique characteristics of soft robotic sensors are explored, namely compliance, flexibility, multifunctionality, sensor nature, surface properties, and material requirements. In addition, a categorization of sensors for soft robotic grippers in terms of modalities has been established, ranging from the tactile and force sensor to the slippage sensor. Various tactile sensors, ranging from piezoelectric sensing to optical sensing, are explored as they are of the utmost importance in soft grippers to effectively address the increasing requirements for intelligence and automation. Finally, taking everything into consideration, a flow diagram has been suggested for selecting sensors specific to soft robotic applications.","url":"https://doi.org/10.3390/s25051508","authors":["Rana MT","Islam MS","Rahman A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25051508","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.1364/oe.563748","name":"Flexible dual-core optical waveguide with variable contact-induced losses for quasi-distributed tactile sensing.","source":"europepmc","abstract":"","url":"https://doi.org/10.1364/oe.563748","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1364/oe.563748","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1038/s41378-025-01108-w","name":"Repurposing traditional China Xuan paper for versatile humidity sensing.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41378-025-01108-w","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41378-025-01108-w","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1038/s41598-025-93888-4","name":"Conditional variational auto encoder based dynamic motion for multitask imitation learning.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-93888-4","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41598-025-93888-4","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.1038/s41598-025-16563-8","name":"Fused RGB and IR image based deep learning detection of dried laver bugak for robotic automation systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-16563-8","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41598-025-16563-8","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1038/s41586-025-09650-3","name":"Ultrasound-driven programmable artificial muscles.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41586-025-09650-3","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41586-025-09650-3","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1371/journal.pone.0323045","name":"RRT-CS: A free-collision planner for capsule-like SCORBOT by iterated learning.","source":"europepmc","abstract":"","url":"https://doi.org/10.1371/journal.pone.0323045","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1371/journal.pone.0323045","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1038/s41378-025-01033-y","name":"Stable manipulating objects with unknown surface morphology via integration of magnetic artificial muscle and adhesive structures.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41378-025-01033-y","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41378-025-01033-y","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1038/s41598-025-92050-4","name":"Design and experiment of automatic grasping manipulator for side-mounted garbage truck.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-92050-4","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41598-025-92050-4","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.1007/s00464-025-11963-3","name":"The evolution of surgical precision: addressing and advancing the hardware of robotic end-effectors.","source":"europepmc","abstract":"","url":"https://doi.org/10.1007/s00464-025-11963-3","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1007/s00464-025-11963-3","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1002/smll.202503393","name":"MXene and PAN-Based Carbon Fiber Enhanced Bimodal Triboelectric Sensor for Robotic Arm Perception and Control.","source":"pubmed","abstract":"Endowing robots with human-like perception and thinking to match the growing intelligentization remains a challenge.

The touchless and tactile perception performance are further improved by a functional layer doped with MXene nanosheets and electrodes composed of PAN-based carbon fibers.

Rapid industry expansion and rising consumer demand for ready-to-eat poultry products have heightened occupational risks and foodborne contamination concerns, necessitating holistic safety strategies. The review examines ergonomic, microbiological, and regulatory risks specific to poultry lines, and maps how state-of-the-art collaborative robots (\"cobots\")-including power and force-limiting arms, adaptive soft grippers, machine vision, and biosensor integration-can support safer, more hygienic, and more productive operations. The authors analyze technical scientific literature (2018-2025) and real-world case studies, highlighting how automation (e.g., vision-guided deboning and intelligent sanitation) can reduce repetitive strain injuries, lower contamination rates, and improve production consistency. The review also addresses the psychological and sociocultural dimensions that affect workforce acceptance, as well as economic and regulatory barriers to adoption, particularly in small- and mid-sized plants.

Due to their small size and locomotor capability, cyborg insects have potential advantages for application in cluttered environments where human cannot operate. Past studies have proposed various cyborg insects using different insect species and custom-made controllers equipped with sensors for desirable tasks. Those cyborg insects were usually equipped with the electronic devices on the back, leading to the loss of useful body shape of the platform organism. Although the body shape of animals is known to contribute to effective locomotion in their living environments, it has been unexamined how the arrangement of electronics to cyborg insect affects its locomotion. Here, we developed a miniature wireless controller that is fully implantable to small insects and demonstrated that the implantation of electronic device enhances traversal performance of the cyborg cockroach. The developed wireless controller was 10 mm in width, 10 mm in length, and 3 mm in height. It served sub-1 GHz communication and electrical signal output for maneuvering locomotion of cockroach. The cockroach with the implant maintained the innate tendency and traversal performance in gap negotiation comparable to intact animals, whereas the cyborg cockroach with the electronics mounted on the back exhibited degraded performance. The automatic stimulation algorithm successfully navigated the cockroach with the implant to the target with a success rate of 90.9%.

broad range of tasks. However, there are growing concerns about their environmental sustainability, as many conventional robotic systems rely on materials that are neither renewable nor degradable. Consequently, significant efforts are being made to develop eco-friendly robots built from sustainable and biodegradable materials. In this context, plants represent a promising direction, as the biomaterials composing plants are biodegradable, and their inherent multifunctionality as living organisms, including sensing, actuation, energy harvesting, and self-healing, makes them strong candidates for realizing biodegradable robotic systems. Moreover, they are abundant and renewable resources. Recent studies have demonstrated plant-based robotic systems that harness some of these features, helping to establish plant robotics as an emerging research field. Among the many functions plants offer, actuation is pivotal, as it enables physical robotic motion, such as locomotion and grasping, which substantially broadens the potential applications of plant robots. Focusing on plant movement, this article reviews key plant species and their behaviors through the perspective of actuation characteristics.

In particular, fruit harvesting robots often rely on object detection or segmentation to identify and localize target fruits. During the model selection process for object detection, the average precision (AP) score typically provides the de facto standard. However, AP is not intuitive for determining which model is most efficient for robotic harvesting. It is based on the intersection-over-union (IoU) of bounding boxes, which reflects only regional overlap. IoU alone cannot reliably predict the success of robotic gripping, as identical IoU scores may yield different results depending on the overlapping shape of the boxes. In this paper, we propose a novel evaluation metric for robotic harvesting. To assess gripping success, our metric uses the center coordinates of bounding boxes and a margin hyperparameter that accounts for the gripper's specifications. We conducted evaluation about popular object detection models on peach and apple datasets. The experimental results showed that the proposed gripping success metric is much more intuitive and helpful in interpreting the performance data.","url":"https://doi.org/10.3390/s25010181","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s25010181","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.48550/arxiv.2511.14432","name":"Mutation Testing for Industrial Robotic Systems","source":"datacite","abstract":"Industrial robotic systems (IRS) are increasingly deployed in diverse environments, where failures can result in severe accidents and costly downtime.

However, traditional mutation operators are poorly suited to robotic programs, which involve message-based commands and interactions with the physical world. This paper explores the adaptation of mutation testing to IRS by defining domain-specific mutation operators that capture the semantics of robot actions and sensor readings. We propose a methodology for generating meaningful mutants at the level of high-level read and write operations, including movement, gripper actions, and sensor noise injection.

This thesis presents a novel design methodology for contact-aided compliant grippers (CGs) that achieve large deformations using topology optimization to create efficient, manufacturable, and organically shaped designs actuated by external loads. The process begins by defining the design problem, including object characteristics, grasp mechanics, and environmental constraints, which are translated into technical requirements like boundary conditions and material choices. A major innovation is the integration of nonlinear contact mechanics and large deformation analysis into the topology optimization framework for spatial designs, enabling self-adaptiveCGs. Unlike traditional approaches that separate structural design and grasp analysis, this method directly synthesizes grippers responsive to complex contact scenarios. The Hill Climbing Mutation Algorithm (HCMA) is used to efficiently explore high-dimensional design spaces, reducing computational costs and avoiding premature convergence. Analytical models support both 2D and 3D implementations. The 2D model uses co-rotational beam elements with frictionless contact under large deformations, while the 3D model employs isogeometric analysisof nonlinear beam structures, with impenetrability enforced via spatial discretization.Three applications demonstrate the methodology: (i) a 2D CG prototype handling objectsfrom 5–20 mm in diameter; (ii) a capsule gripper for delicate lymph node extraction in breastcancer surgery; and (iii) a fully 3D topology-optimized gripper with novel organic shapes andreduced actuation needs. This thesis offers a reproducible framework for CGs, validated through modeling, simulation, and prototyping. It supports applications in space, food, medicine, andaerial robotics, advancing adaptive, energy-efficient designs that minimize reliance on external tools and enable future innovation in soft robotic manipulation.","url":"https://doi.org/10.18154/rwth-2025-07422","authors":["Hermoza Llanos, Estefania Andrea"],"tags":["Hochschulschrift"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.18154/rwth-2025-07422","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:26.468Z"},{"id":"doi:10.48550/arxiv.2509.18830","name":"DexSkin: High-Coverage Conformable Robotic Skin for Learning Contact-Rich Manipulation","source":"datacite","abstract":"Human skin provides a rich tactile sensing stream, localizing intentional and unintentional contact events over a large and contoured region. Replicating these tactile sensing capabilities for dexterous robotic manipulation systems remains a longstanding challenge. In this work, we take a step towards this goal by introducing DexSkin. DexSkin is a soft, conformable capacitive electronic skin that enables sensitive, localized, and calibratable tactile sensing, and can be tailored to varying geometries. We demonstrate its efficacy for learning downstream robotic manipulation by sensorizing a pair of parallel jaw gripper fingers, providing tactile coverage across almost the entire finger surfaces. We empirically evaluate DexSkin's capabilities in learning challenging manipulation tasks that require sensing coverage across the entire surface of the fingers, such as reorienting objects in hand and wrapping elastic bands around boxes, in a learning-from-demonstration framework. We then show that, critically for data-driven approaches, DexSkin can be calibrated to enable model transfer across sensor instances, and demonstrate its applicability to online reinforcement learning on real robots. Our results highlight DexSkin's suitability and practicality for learning real-world, contact-rich manipulation.

To address this limitation, we introduce Graph-Fused Vision-Language-Action (GF-VLA), a unified framework that enables dual-arm robotic systems to perform task-level reasoning and execution directly from RGB-D human demonstrations. GF-VLA employs an information-theoretic approach to extract task-relevant cues, selectively highlighting critical hand-object and object-object interactions. These cues are structured into temporally ordered scene graphs, which are subsequently integrated with a language-conditioned transformer to produce hierarchical behavior trees and interpretable Cartesian motion primitives. To enhance efficiency in bimanual execution, we propose a cross-arm allocation strategy that autonomously determines gripper assignment without requiring explicit geometric modeling. We validate GF-VLA on four dual-arm block assembly benchmarks involving symbolic structure construction and spatial generalization. Empirical results demonstrate that the proposed representation achieves over 95% graph accuracy and 93% subtask segmentation, enabling the language-action planner to generate robust, interpretable task policies. When deployed on a dual-arm robot, these policies attain 94% grasp reliability, 89% placement accuracy, and 90% overall task success across stacking, letter-formation, and geometric reconfiguration tasks, evidencing strong generalization and robustness under diverse spatial and semantic variations.","url":"https://doi.org/10.48550/arxiv.2509.07957","authors":["Li, Shunlei","Gao, Longsen","Cao, Jiuwen","Hu, Yingbai"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2509.07957","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:26.468Z"},{"id":"doi:10.6084/m9.figshare.27959112","name":"Results of Image Prediction","source":"datacite","abstract":"Update 2025-09-04 We uploaded video and frames to illustrate more detail.-----------------------------------------------------------------------------------All videos (GIFs), consistent with the results presented in the paper, use the first eight frames as the model's input and the subsequent four frames as the model's output.

Existing datasets have significantly advanced learning in manipulation but are primarily focused on simpler tasks like object rearrangement, falling short of capturing the complexity and physical dynamics involved in assembly and disassembly. To bridge this gap, we present REASSEMBLE (Robotic assEmbly disASSEMBLy datasEt), a new dataset designed specifically for contact-rich manipulation tasks. Built around the NIST Assembly Task Board 1 benchmark, REASSEMBLE includes four actions (pick, insert, remove, and place) involving 17 objects. The dataset contains 4,551 demonstrations, of which 4,035 were successful, spanning a total of 781 minutes. Our dataset features multi-modal sensor data including event cameras, force-torque sensors, microphones, and multi-view RGB cameras. This diverse dataset supports research in areas such as learning contact-rich manipulation, task condition identification, action segmentation, and more.

Long horizon: Demonstrations in the REASSEMBLE dataset cover long horizon tasks and actions which usually span multiple steps. Hierarchical labels: REASSEMBLE contains actions segmentation labels at two hierarchical levels. 🔴 Dataset Collection Each demonstration starts by randomizing the board and object poses, after which an operator teleoperates the robot to assemble and disassemble the board while narrating their actions and marking task segment boundaries with key presses. The narrated descriptions are transcribed using Whisper [1], and the board and camera poses are measured at the beginning using a motion capture system, though continuous tracking is avoided due to interference with the event camera. Sensory data is recorded with rosbag and later post-processed into HDF5 files without downsampling or synchronization, preserving raw data and timestamps for future flexibility. To reduce memory usage, video and audio are stored as encoded MP4 and MP3 files, respectively. Transcription errors are corrected automatically or manually, and a custom visualization tool is used to validate the synchronization and correctness of all data and annotations. Missing or incorrect entries are identified and corrected, ensuring the dataset’s completeness. Low-level Skill annotations were added manually after data collection, and all labels were carefully reviewed to ensure accuracy. 📑 Dataset Structure The dataset consists of several HDF5 (.h5) and JSON (.json) files, organized into two directories. The poses directory contains the JSON files, which store the poses of the cameras and the board in the world coordinate frame. The data directory contains the HDF5 files, which store the sensory readings and annotations collected as part of the REASSEMBLE dataset. Each JSON file can be matched with its corresponding HDF5 file based on their filenames, which include the timestamp when the data was recorded. For example, 2025-01-09-13-59-54_poses.json corresponds to 2025-01-09-13-59-54.h5.

To reduce memory usage, video and audio are stored as encoded MP4 and MP3 files, respectively. Transcription errors are corrected automatically or manually, and a custom visualization tool is used to validate the synchronization and correctness of all data and annotations. Missing or incorrect entries are identified and corrected, ensuring the dataset’s completeness. Low-level Skill annotations were added manually after data collection, and all labels were carefully reviewed to ensure accuracy. 📑 Dataset Structure The dataset consists of several HDF5 (.h5) and JSON (.json) files, organized into two directories. The poses directory contains the JSON files, which store the poses of the cameras and the board in the world coordinate frame. The data directory contains the HDF5 files, which store the sensory readings and annotations collected as part of the REASSEMBLE dataset. Each JSON file can be matched with its corresponding HDF5 file based on their filenames, which include the timestamp when the data was recorded. For example, 2025-01-09-13-59-54_poses.json corresponds to 2025-01-09-13-59-54.h5. The structure of the JSON files is as follows: {\"Hama1\": [ [x ,y, z], [qx, qy, qz, qw] ], \"Hama2\": [ [x ,y, z], [qx, qy, qz, qw] ], \"DAVIS346\": [ [x ,y, z], [qx, qy, qz, qw] ], \"NIST_Board1\": [ [x ,y, z], [qx, qy, qz, qw] ] } [x, y, z] represent the position of the object, and [qx, qy, qz, qw] represent its orientation as a quaternion.

However, hindsight relabeling can struggle in object-centric domains. For example, suppose that the goal space consists of a robotic arm pushing a particular target block to a goal location. In this case, hindsight relabeling will give high rewards to any trajectory that does not interact with the block. However, these behaviors are only useful when the object is already at the goal -- an extremely rare case in practice. A dataset dominated by these kinds of trajectories can complicate learning and lead to failures. In object-centric domains, one key intuition is that meaningful trajectories are often characterized by object-object interactions such as pushing the block with the gripper. To leverage this intuition, we introduce Hindsight Relabeling using Interactions (HInt), which combines interactions with hindsight relabeling to improve the sample efficiency of downstream RL. However because interactions do not have a consensus statistical definition tractable for downstream GCRL, we propose a definition of interactions based on the concept of null counterfactual: a cause object is interacting with a target object if, in a world where the cause object did not exist, the target object would have different transition dynamics. We leverage this definition to infer interactions in Null Counterfactual Interaction Inference (NCII), which uses a \"nulling'' operation with a learned model to infer interactions. NCII is able to achieve significantly improved interaction inference accuracy in both simple linear dynamics domains and dynamic robotic domains in Robosuite, Robot Air Hockey, and Franka Kitchen and HInt improves sample efficiency by up to 4x.","url":"https://doi.org/10.48550/arxiv.2505.03172","authors":["Chuck, Caleb","Feng, Fan","Qi, Carl","Shi, Chang","Agarwal, Siddhant","Zhang, Amy","Niekum, Scott"],"tags":["Machine Learning (cs.LG)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2505.03172","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:26.468Z"},{"id":"doi:10.48550/arxiv.2505.03046","name":"Sim2Real Transfer for Vision-Based Grasp Verification","source":"datacite","abstract":"The verification of successful grasps is a crucial aspect of robot manipulation, particularly when handling deformable objects.

Existing approaches fall into two categories: keyframe-based strategies, which predict gripper poses in keyframes and execute them via motion planners, and continuous control methods, which estimate actions sequentially at each timestep. The keyframe-based method lacks inter-frame supervision, struggling to perform consistently or execute curved motions, while the continuous method suffers from weaker spatial perception. To address these issues, this paper introduces an end-to-end framework PPI (keyPose and Pointflow Interface), which integrates the prediction of target gripper poses and object pointflow with the continuous actions estimation. These interfaces enable the model to effectively attend to the target manipulation area, while the overall framework guides diverse and collision-free trajectories. By combining interface predictions with continuous actions estimation, PPI demonstrates superior performance in diverse bimanual manipulation tasks, providing enhanced spatial localization and satisfying flexibility in handling movement restrictions. In extensive evaluations, PPI significantly outperforms prior methods in both simulated and real-world experiments, achieving state-of-the-art performance with a +16.1% improvement on the RLBench2 simulation benchmark and an average of +27.5% gain across four challenging real-world tasks. Notably, PPI exhibits strong stability, high precision, and remarkable generalization capabilities in real-world scenarios.

With an aim to get more general and practical grasp models, in this paper, we investigate the problem named Task-Oriented 6-DoF Grasp Pose Detection in Clutters (TO6DGC), which extends the task-oriented problem to a more general 6-DOF Grasp Pose Detection in Cluttered (multi-object) scenario. To this end, we construct a large-scale 6-DoF task-oriented grasping dataset, 6-DoF Task Grasp (6DTG), which features 4391 cluttered scenes with over 2 million 6-DoF grasp poses. Each grasp is annotated with a specific task, involving 6 tasks and 198 objects in total. Moreover, we propose One-Stage TaskGrasp (OSTG), a strong baseline to address the TO6DGC problem. Our OSTG adopts a task-oriented point selection strategy to detect where to grasp, and a task-oriented grasp generation module to decide how to grasp given a specific task. To evaluate the effectiveness of OSTG, extensive experiments are conducted on 6DTG. The results show that our method outperforms various baselines on multiple metrics.

Soft robotic hands try to address this by leveraging passive compliance, a characteristic that is crucial to the adaptability of the human hand, to achieve more robust manipulation while reducing reliance on high-resolution sensing and complex control. Further improvements in terms of precision and postural stability in manipulation tasks are achieved through the integration of variable stiffness mechanisms, but these tend to lack residual compliance, be bulky and have slow response times. To address these limitations, this work introduces a Compliant Joint Jamming mechanism for anthropomorphic fingers that exhibits passive residual compliance and adjustable stiffness, while achieving a range of motion in line with that of human interphalangeal joints. The stiffness range provided by the mechanism is controllable from 0.48 Nm/rad to 1.95 Nm/rad (a 4x increase). Repeatability, hysteresis and stiffness were also characterized as a function of the jamming force. To demonstrate the importance of the passive residual compliance afforded by the proposed system, a peg-in-hole task was conducted, which showed a 60% higher success rate for a gripper integrating our joint design when compared to a rigid one.","url":"https://doi.org/10.48550/arxiv.2502.04190","authors":["Westermann, Maximilian","Pontin, Marco","Costi, Leone","Albini, Alessandro","Maiolino, Perla"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2502.04190","addedAt":"2026-08-31T06:34:26.468Z","updatedAt":"2026-08-31T06:34:26.468Z"},{"id":"doi:10.48550/arxiv.2411.08566","name":"Grammarization-Based Grasping with Deep Multi-Autoencoder Latent Space Exploration by Reinforcement Learning Agent","source":"datacite","abstract":"Grasping by a robot in unstructured environments is deemed a critical challenge because of the requirement for effective adaptation to a wide variation in object geometries, material properties, and other environmental factors. In this paper, we propose a novel framework for robotic grasping based on the idea of compressing high-dimensional target and gripper features in a common latent space using a set of autoencoders. Our approach simplifies grasping by using three autoencoders dedicated to the target, the gripper, and a third one that fuses their latent representations. This allows the RL agent to achieve higher learning rates at the initial stages of exploration of a new environment, as well as at non-zero shot grasp attempts. The agent explores the latent space of the third autoencoder for better quality grasp without explicit reconstruction of objects. By implementing the PoWER algorithm into the RL training process, updates on the agent's policy will be made through the perturbation in the reward-weighted latent space. The successful exploration efficiently constrains both position and pose integrity for feasible executions of grasps.

The research introduces a new grasping apparatus named Compliant Self-Adaptive Variable Stiffness Robotic Gripper (CS-VSRG) that unifies shape-conforming and adaptive compliance features to improve handling operations. Key to this innovation is the design of Self-Adaptive Variable Stiffness fingers which are constructed by the combination of three separate layers for high-stiffness outer and medium-stiffness middle and low-stiffness inner components. Each layer has been engineered to choose specific objects when gripping forces are applied. Fragile objects with a small grasping force are needed only to contact the low-stiffness layer. As the required grasping force increases, the deformation leads to the contact layer extending to the middle or outer layers through self-adaptive stiffness transition. This allows for adapting to various types of objects while maintaining a firm grasp. A comprehensive control strategy and system design are also developed and analyzed in this paper. Finite element analysis (FEA) simulations are also performed to validate the gripper. The stress distribution, deformation characteristics, and stiffness regulation of the layered structure are studied. A physical prototype is fabricated and an experimental grasping demonstration is performed to evaluate the actual performance. The results confirm that the gripper can dynamically adjust the stiffness of the finger layers involved in the grasping process, thereby enhancing both adaptability and robustness. Additionally, the proposed design is characterized by low cost, high reliability, and structural simplicity, making it well-suited for large-scale industrial applications that require cost-effective robotic operations. It can also be integrated as a component of a dexterous robotic hand.","url":"https://doi.org/10.1115/detc2025-168656","authors":["Ashley Creighton","Wyatt Ross","Ryan Rushing","Matthew Lancaster","Peter Salvucci","Xiaoou Yang","Dongming Gan","Jiaming Fu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-27T21:42:19Z","doi":"10.1115/detc2025-168656","addedAt":"2026-08-31T06:34:30.172Z","updatedAt":"2026-08-31T06:34:30.172Z"},{"id":"doi:10.1007/978-981-96-1464-6_6","name":"Multi-Layer Multi-Material Variable Stiffness Soft Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-96-1464-6_6","authors":["Liming Dong","Yu Shan","Yanzhi Zhao","Haobo Wang","Linquan Song"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-13T10:38:19Z","doi":"10.1007/978-981-96-1464-6_6","addedAt":"2026-08-31T06:34:30.172Z","updatedAt":"2026-08-31T06:34:33.058Z"},{"id":"doi:10.1109/icma65362.2025.11120829","name":"A Soft Robotic Gripper with Variable Grasping Force Based on Jamming Phenomenon","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icma65362.2025.11120829","authors":["Yige Peng","Jianjun Yuan","Zhengtao Hu","Liang Du","Sheng Bao","Mahmoud Magdy"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-08-22T23:57:29Z","doi":"10.1109/icma65362.2025.11120829","addedAt":"2026-08-31T06:34:30.172Z","updatedAt":"2026-08-31T06:34:30.172Z"},{"id":"doi:10.1109/lra.2025.3608635","name":"Compact Robotic Gripper With Tandem Actuation for Selective Apple Harvesting","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2025.3608635","authors":["Alejandro Velasquez","Cindy Grimm","Joseph R.

The presented method uses an RGBD camera mounted on the robotic arm end effector to localize the object relative to the robotic arm base. The design of a gripper and a control method based on force and torque measurements provides a robust means of picking up an object and compensating for the influence of relative ship motion due to waves and localization error. The components of the proposed method and the entire manipulation procedure have been tested both in a laboratory environment and in a real‐world maritime scenario, demonstrating reliable performance. Laboratory experiments have demonstrated that the gripper design allows for picking up objects with an allowable positioning error of up to 20 cm in the direction, 4 cm in the direction, and in the yaw angle. For the entire pick‐up procedure, a 98.3% success rate in laboratory tests demonstrates the repeatability and resilience of the proposed system. The experiment conducted in a real maritime scenario showed successful pick‐up of objects using a robotic arm mounted on an autonomous catamaran, both on calm seas and in conditions with small waves.","url":"https://doi.org/10.1002/rob.70113","authors":["Goran Vasiljevic","Dario Stuhne"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-11-10T08:45:47Z","doi":"10.1002/rob.70113","addedAt":"2026-08-31T06:34:30.172Z","updatedAt":"2026-08-31T06:34:32.659Z"},{"id":"doi:10.1109/icarm65671.2025.11293551","name":"Double-X Gripper: A Novel Scalable Adaptive Robot Gripper for Pinching and Scooping Under Environmental Constraints","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icarm65671.2025.11293551","authors":["Jiawen Wang","Xinyi Xia","Xiangrong Xu","Wenzeng Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-22T18:39:45Z","doi":"10.1109/icarm65671.2025.11293551","addedAt":"2026-08-31T06:34:30.172Z","updatedAt":"2026-08-31T06:34:30.172Z"},{"id":"doi:10.1007/978-981-97-6806-6_11","name":"Design and Development of Compliant Robotic Gripper by 3D-Printing Technology","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-97-6806-6_11","authors":["Neeta Sahay","Kaustav Laskar","Andolan Majumdar","Sourav Sardar"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-28T22:15:10Z","doi":"10.1007/978-981-97-6806-6_11","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1007/978-3-031-71301-9_2","name":"A Soft Robotic Gripper for Pancake Handling: Design, Modelling, and Experimental Assessment","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-031-71301-9_2","authors":["Ser Vin Chan","Behnaz Sohani","Khaled Goher"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-01-01T01:02:58Z","doi":"10.1007/978-3-031-71301-9_2","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1088/1742-6596/2784/1/012026","name":"Pneumatically Operated Tendril-based Soft Hyper-Redundant Robotic Gripper","source":"crossref","abstract":"Abstract The present work aims to design a soft, hyper redundant robotic gripper inspired by natural tendrils. The development of automation also requires extensive study in the field of biomimetic robotics. Most robotic systems are generally built using traditional rigid materials, such as hard plastics and metals. Creating accurate robotic systems necessitates the assembly of firm components connected at specific joints. Nonetheless, crafting a robotic system modeled after natural systems, comprising continuous deformable materials, is anticipated to match or exceed the capabilities of rigid robotic systems. Soft and highly redundant robotic grippers offer nearly limitless degrees of freedom (DOF) and elevated levels of kinematic redundancy. In the present work, a soft robotic gripper is proposed, inspired by plant tendrils that deform helically to hold the object on actuation. The work describes the initial design, material selection, method, important design parameters, an actuation mechanism and the simulation and analysis of the soft gripper. Such studies will be useful to industries and researchers in automation and biomimetic robotic systems.","url":"https://doi.org/10.1088/1742-6596/2784/1/012026","authors":["Shubhashis Sanyal","Anuj Kumar Shukla","Hrishi Sharad Pinjan","Piyush Tailor","Pyla Pavan Kumar","Suman Saurav","Surjeet Kumar Bhargav"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-19T06:19:11Z","doi":"10.1088/1742-6596/2784/1/012026","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1109/vrw62533.2024.00015","name":"Stiffness Simulation with Haptic Feedback Using Robotic Gripper and Paper Origami as End-Effector","source":"crossref","abstract":"","url":"https://doi.org/10.1109/vrw62533.2024.00015","authors":["Khrystyna Vasylevska","Mohammad Ghazanfari","Kiumars Sharifmoghaddam","Soroosh Mortezapoor","Emanuel Vonach","Hugo Brument","Georg Nawratil","Hannes Kaufmann"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-05-29T17:24:08Z","doi":"10.1109/vrw62533.2024.00015","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:31.425Z"},{"id":"doi:10.1007/978-981-99-7445-0_1","name":"Design and Analysis of an Adaptive Robotic Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-99-7445-0_1","authors":["Yashraj M.

With the aging of the global population, it is supposed to develop robotic grasping systems to replace manual labor. However, damage-less grasping of fragile fruit is the key problem in robotization. Inappropriate grasping force will result in damage, early-stage bruise, or slip. Benefits from the advantages of softness and compliance of a pneumatic-driven soft gripper have been widely adopted for agricultural product and food manipulation. Nevertheless, pneumatic gripper is a complex, multivariable, nonlinear, and long time-delay control system, which is difficult to achieve robust closed-loop grasping force control. In this study, we aim to solve this problem and developed a robotic grasping force control system with pneumatic gripper and matrix force sensor. The force distribution condition was explored to tackle the problem in changing of the main contact point. A double closed-loop control method was proposed based on Kalman filter (KF) and proportion integration differentiation controller with dead band. The external and internal control loops were force controller and air pressure of the pump controller, respectively. The double closed-loop controller with dead band achieved robust grasping force control through air pressure. The experimental results validated the effectiveness of the KF method for denoising and the matrix force visualization method for exploring grasping mechanism. Ablation studies were carried out to demonstrate the effectiveness of the multiple grasping force sensing units in matrix form and the dead band in the controller. The maximum steady-state error was 0.07 N. In addition, the generalization performance and the antidisturbance ability of the grasping force control system was also validated.

Contribution This study presents a novel YOLOv8-PnP hybrid framework integrating real-time object detection with 6 degree of freedom pose estimation for precision airflow based pollination. The system employs a custom-designed Air Pollenmatic end-effector integrated with a Hello Robot Stretch platform through ROS-based visual servoing control. Results Validation on 2,100 annotated greenhouse images demonstrated 95.8% precision, 94.6% recall, and 97.7% mAP@0.5 at 28.5 FPS (11.1 ms inference). Field trials achieved 92.5% pollination attempt rate and 85.6% success rate, yielding 79.2% overall efficacy-an 8.3 percentage point improvement over contact-based methods. Impact This contactless approach eliminates mechanical flower damage, reduces disease transmission risk, and advances the feasibility of fully autonomous greenhouse pollination systems.","url":"https://doi.org/10.3389/fpls.2026.1771732","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/fpls.2026.1771732","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3389/frobt.2024.1351932","name":"Evaluation of different robotic grippers for simultaneous multi-object grasping.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2024.1351932","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1351932","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s24196407","name":"Design and Experimental Test of Rope-Driven Force Sensing Flexible Gripper.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s24196407","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24196407","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/s24237790","name":"MST-G: Micro Suction Tape Gripper Climbing Robot with Active Detachment Capability.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s24237790","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24237790","addedAt":"2026-08-31T06:34:31.425Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3389/fpls.2025.1734507","name":"Technology-driven approaches to intelligent mechanical weed control: a systematic review for sustainable weed management.","source":"europepmc","abstract":"The intensifying global demand for sustainable agriculture has necessitated innovation in weed management, particularly through intelligent, non-chemical alternatives. Among these, smart mechanical weeding systems integrating artificial intelligence (AI), machine vision, and robotics are emerging as transformative tools for precise and eco-friendly weed control. While several recent reviews have examined intelligent weeding or machine vision-based weed management more broadly, a comprehensive and systematically structured synthesis focusing specifically on AI-driven mechanical weeding systems that integrate both vision and robotic actuation remains limited. This study presents a systematic review of 176 technical papers published between 2000 and 2024, with in-depth analysis of 33 key works, aiming to explore the design and performance of intelligent mechanical weed control systems in precision agriculture. The review investigates foundational mechanical weeding methods, recent advances in sensor integration and weed detection algorithms, and the use of robotic platforms for intra- and inter-row weeding. It highlights the critical role of RGB, LiDAR, hyperspectral sensors, and deep learning models in enabling real-time, selective weed removal. Comparative case studies showcase end effectors, control architecture, sensors, and techniques involved across diverse platforms. While significant progress has been made, challenges persist in weed-crop differentiation, model generalization, real-time actuation, and economic feasibility. The review proposes a set of design and operational guidelines addressing sensor fusion, adaptive tooling, platform modularity, and user-centric interfaces. This work provides a targeted, system-level roadmap for researchers, developers, and stakeholders in agricultural robotics, offering insights into current capabilities, gaps, and future directions to advance intelligent mechanical weeding for scalable and sustainable food

reprogramming and adaptive reproduction of contact-rich assembly.","source":"europepmc","abstract":"Introduction Modern manufacturing demands flexible, robust robotic assembly systems capable of handling variable part geometries and dynamic task configurations. Current approaches often suffer from limited generalization, high sample complexity, and the need for extensive reconfiguration or retraining when task parameters change. This paper addresses these limitations by introducing a novel framework that enables adaptive reproduction of kinesthetically taught, contact-rich assembly policies, using only force/torque and proprioceptive sensing. Methods The approach combines three components: i. synchronized wrench-motion Dynamic Movement Primitives (wDMPs) that encode coupled motion and wrench profiles from a single demonstration; ii. an uncertainty-aware Model Predictive Controller (MPC) that updates its model online to enable compliant and adaptive contact handling using uncertainty estimated via a Gaussian Mixture Model (GMM); and iii. a neural contact classifier based on Adaptive Resonance Theory (ART) that distinguishes intended contacts from unintended misalignments and coordinates transitions between assembly stages. Results and discussion Trained on just two demonstrations, one kinesthetic teaching and one assisted successful reproduction, the framework was evaluated on standard benchmarks and real-world industrial scenarios, including peg-in-hole, plug insertion, and disc brake assemblies. Across 47 assemblies, our framework increased the success rate from 29.8% to 83% in comparison to a classic, nonadaptive compliant controller, and demonstrated improved robustness and transferability over baseline controllers under geometric and pose variations. This contributes towards enabling agile, customizable production with minimal reprogramming effort.","url":"https://doi.org/10.3389/frobt.2026.1746577","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1746577","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.19852/j.cnki.jtcm.2025.01.020","name":"Research on acupuncture robots based on the OptiTrack motion capture system and a robotic arm.","source":"europepmc","abstract":"","url":"https://doi.org/10.19852/j.cnki.jtcm.2025.01.020","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.19852/j.cnki.jtcm.2025.01.020","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.3390/s25041137","name":"Machine Vision-Assisted Design of End Effector Pose in Robotic Mixed Depalletizing of Heterogeneous Cargo.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25041137","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25041137","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3390/biomimetics10010054","name":"Advances in Biomimetics: The Power of Diversity.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10010054","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10010054","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.3389/fpls.2026.1853570","name":"Target-conditioned flow-matching policy for citrus harvesting robot pre-grasp approach behavior learning.","source":"europepmc","abstract":"Introduction Fruit harvesting in natural orchards remains challenging because target fruits are distributed in cluttered and unstructured environments. In the pre-grasp approach stage of multi-fruit citrus harvesting, three issues are particularly critical: limited demonstration data, target ambiguity, and the need for stable and precise local approach motions. Methods To address these issues, this study proposes a Target-Conditioned Flow-Matching Policy (TCFM Policy), which integrates image observations, robot state history, and explicit target geometric conditions, uses a dual-branch visual representation to encode both global scene context and local end-effector details, and predicts future multi-step TCP trajectories through conditional flow matching. To reduce overfitting to global appearance under small-sample conditions, a target-oriented visual augmentation strategy is further introduced for the global branch during training. Results A real-world dataset containing 160 valid demonstration episodes was collected on a UR5-based citrus harvesting platform using VR teleoperation. In 50 target-specified multi-fruit trials, the full model achieved a success rate of 76%, a target-picking error rate of 4%, and a picking-point offset rate of 20%. Discussion A fairness-aligned comparison with a target-conditioned diffusion-policy baseline further shows that the proposed method achieves lower offline trajectory error and better online target-specified approach performance under the same training setting. Ablation results indicate that the ROI branch mainly improves final alignment, while the target-oriented augmentation mainly improves target consistency. These results indicate that explicit target conditioning, dual-branch visual encoding, and conditional flow matching jointly support accurate target selection and relatively stable pre-grasp approach execution in small-sample multi-fruit citrus scenes.","url":"https://doi.org/10.3389/fpls.2026.1853570","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/fpls.2026.1853570","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1080/08940886.2026.2647709","name":"Structural Biology Resources at an Upgrading Synchrotron Advanced Light Source.","source":"europepmc","abstract":"","url":"https://doi.org/10.1080/08940886.2026.2647709","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1080/08940886.2026.2647709","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.3390/s24144631","name":"Sensor-Enhanced Smart Gripper Development for Automated Meat Processing.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s24144631","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24144631","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3389/frobt.2025.1621033","name":"Large language model-driven natural language interaction control framework for single-operator bimanual teleoperation.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2025.1621033","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1621033","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.3389/frobt.2024.1450097","name":"Embodied intelligence for drumming; a reinforcement learning approach to drumming robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/frobt.2024.1450097","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1450097","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3390/s24247958","name":"Cascaded Feature Fusion Grasping Network for Real-Time Robotic Systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s24247958","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24247958","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3390/s25154824","name":"Vision-Based 6D Pose Analytics Solution for High-Precision Industrial Robot Pick-and-Place Applications.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25154824","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25154824","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3389/fpls.2026.1836301","name":"NRLC-YOLO for lightweight detection and grasp positioning of latex cups in rubber plantations.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/fpls.2026.1836301","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/fpls.2026.1836301","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1126/sciadv.aec8124","name":"High-energy-density aqueous magnesium metal battery textiles enable ultrasensitive pressure sensing across -40° to 100°C.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.aec8124","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1126/sciadv.aec8124","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1016/j.dib.2025.112234","name":"A multimodal dataset for human robot collaborative systems: Experimental data.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.dib.2025.112234","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1016/j.dib.2025.112234","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3389/frobt.2025.1581154","name":"A multi-modal sensing system for human-robot interaction through tactile and proximity data.","source":"pubmed","abstract":"The rapid advancement of collaborative robotics has driven significant interest in Human-Robot Interaction (HRI), particularly in scenarios where robots work alongside humans.

This paper presents a prediction model based on the Transformer-based Informer framework for accurate and efficient position estimation, combined with a Four-State Hidden Markov Model (4-State HMM) to simulate realistic packet loss scenarios. The proposed approach addresses challenges such as network delays, jitter, and packet loss to ensure reliable and precise operation in remote surgical applications. The method integrates the optimization problem into the Informer model by embedding constraints such as energy efficiency, smoothness, and robustness into its training process using a differentiable optimization layer. The Informer framework uses features such as ProbSparse attention, attention distilling, and a generative-style decoder to focus on position-critical features while maintaining a low computational complexity of O(LlogL). The method is evaluated using the JIGSAWS dataset, achieving a prediction accuracy of over 90% under various network scenarios. A comparison with models such as TCN, RNN, and LSTM demonstrates the Informer framework's superior performance in handling position prediction and meeting real-time requirements, making it suitable for Tactile Internet-enabled robotic surgery.","url":"https://doi.org/10.3390/s25103067","authors":["Lashari MH","Ahmed S","Batayneh W","Khokhar A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25103067","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:50.038Z"},{"id":"doi:10.1038/s41598-025-93490-8","name":"Robot multi-target high performance grasping detection based on random sub-path fusion.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-93490-8","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41598-025-93490-8","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.1038/s41467-024-48903-z","name":"Skin-inspired, sensory robots for electronic implants.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-024-48903-z","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1038/s41467-024-48903-z","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3390/biomimetics9100612","name":"Autonomous Robot Task Execution in Flexible Manufacturing: Integrating PDDL and Behavior Trees in ARIAC 2023.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics9100612","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/biomimetics9100612","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3390/foods15111944","name":"Quality Detection for Dragon Fruit Based on the End-of-Arm Spectral Sensor of the Harvesting Robot.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/foods15111944","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/foods15111944","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1002/exp.20240120","name":"Layout Optimization of the Six-Axis Industrial Robot Based on an Improved Whale Algorithm for Reducing Energy Consumption in Industry 5.0.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/exp.20240120","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/exp.20240120","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3389/fneur.2025.1680215","name":"Integrated bio-cooperative robotic platform for virtual cognitive training in Parkinson's disease: design and methodology of the OPERA project.","source":"europepmc","abstract":"","url":"https://doi.org/10.3389/fneur.2025.1680215","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/fneur.2025.1680215","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1038/s41378-024-00813-2","name":"Deep learning-assisted object recognition with hybrid triboelectric-capacitive tactile sensor.","source":"pubmed","abstract":"Tactile sensors play a critical role in robotic intelligence and human-machine interaction.

The triboelectric sensing unit is sensitive to the surface material and texture of the grasped objects, while the capacitive sensing unit responds to the object's hardness. By combining signals from the two sensing units, tactile object recognition can be achieved among not only different objects but also the same object in different states. In addition, both the triboelectric layer and the capacitor dielectric layer were fabricated through the same manufacturing process. Furthermore, deep learning was employed to assist the tactile sensor in accurate object recognition. As a demonstration, the identification of 12 samples was implemented using this hybrid tactile sensor, and an recognition accuracy of 98.46% was achieved. Overall, the proposed hybrid tactile sensor has shown great potential in robotic perception and tactile intelligence.","url":"https://doi.org/10.1038/s41378-024-00813-2","authors":["Xie Y","Cheng H","Yuan C","Zheng L","Peng Z","Meng B"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1038/s41378-024-00813-2","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.1007/s10068-024-01813-8","name":"Plant simulation for robot automation system of deep-frying process of &lt;i&gt;Kimbugak&lt;/i&gt;.","source":"europepmc","abstract":"","url":"https://doi.org/10.1007/s10068-024-01813-8","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1007/s10068-024-01813-8","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.1038/s41467-025-63706-6","name":"Optimized user-guided motion control of modular robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-63706-6","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41467-025-63706-6","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:35.625Z"},{"id":"doi:10.1016/j.mex.2024.103111","name":"Numerical and experimental methods for the assessment of a human finger-inspired soft pneumatic actuator for gripping applications.","source":"europepmc","abstract":"The increasing demand for soft robotic systems in agricultural, biomedical and other applications has driven the development of actuators that can mimic the flexibility and adaptability of human muscles. Several studies have explored the design and implementation of soft actuators for robotic applications, however, there is a need for soft actuators demonstrating delicate gripping capabilities but also excel in specific biomedical applications, such as therapeutic massaging. The objective of this work is to develop a multi-finger soft pneumatic actuator mimicking human fingers for Ayurvedic therapeutic massaging and gripping applications. The actuator is geometrically modeled to mimic the dexterity and flexibility of a human finger and its mechanical behavior such as bending angle and gripping force under air pressure is studied through finite element analysis (FEA). The simulation results are experimentally validated. The finger-based actuator is fabricated using liquid silicone rubber, and its performance namely, bending deformation and gripping force generated at various pressure is determined and these results are compared with the simulated test cases. The study also provides a detailed analysis of the performance of the actuator, thus providing detailed insights into its applicability in therapeutic purposes.•Human finger inspired actuators are expected to demonstrate the dexterity and flexibility of human hands, which poses challenges in its modeling and analysis.•The load carrying capacity and bending movements of the actuator is assessed

of a Two-Finger Haptic Robotic Hand with Novel Stiffness Detection and Impedance Control.","source":"pubmed","abstract":"Haptic hands and grippers, designed to enable skillful object manipulation, are pivotal for high-precision interaction with environments. These technologies are particularly vital in fields such as minimally invasive surgery, where they enhance surgical accuracy and tactile feedback: in the development of advanced prosthetic limbs, offering users improved functionality and a more natural sense of touch, and within industrial automation and manufacturing, they contribute to more efficient, safe, and flexible production processes. This paper presents the development of a two-finger robotic hand that employs simple yet precise strategies to manipulate objects without damaging or dropping them. Our innovative approach fused force-sensitive resistor (FSR) sensors with the average current of servomotors to enhance both the speed and accuracy of grasping. Therefore, we aim to create a grasping mechanism that is more dexterous than grippers and less complex than robotic hands. To achieve this goal, we designed a two-finger robotic hand with two degrees of freedom on each finger; an FSR was integrated into each fingertip to enable object categorization and the detection of the initial contact. Subsequently, servomotor currents were monitored continuously to implement impedance control and maintain the grasp of objects in a wide range of stiffness. The proposed hand categorized objects' stiffness upon initial contact and exerted accurate force by fusing FSR and the motor currents. An experimental test was conducted using a Yale-CMU-Berkeley (YCB) object set consisted of a foam ball, an empty soda can, an apple, a glass cup, a plastic cup, and a small milk packet. The robotic hand successfully picked up these objects from a table and sat them down without inflicting any damage or dropping them midway. Our results represent a significant step forward in developing haptic robotic hands with advanced object perception and manipulation capabilities.","url":"https://doi.org/10.3390/s24082585","authors":["Mohammadi V","Shahbad R","Hosseini M","Gholampour MH","Shiry Ghidary S","Najafi F","Behboodi A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s24082585","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:51.327Z"},{"id":"doi:10.3390/s25226844","name":"Fusion of Robotics, AI, and Thermal Imaging Technologies for Intelligent Precision Agriculture Systems.","source":"europepmc","abstract":"The world population is expected to grow to over 10 billion by 2050 and therefore impose further stress on food production. Precision agriculture has become the main approach used to enhance productivity with sustainability in agricultural production. This paper conducts a technical review of how robotics, artificial intelligence (AI), and thermal imaging (TI) technologies transform precision agriculture operations, focusing on sensing, automation, and farm decision making. Agricultural robots promote labor solutions and efficiency by utilizing their sensing devices and kinematics in planting, spraying, and harvesting. Through accurate assessment of pests/diseases and quality assurance of the harvested crops, AI and TI bring efficiency to the crop monitoring sector. Different deep learning models are employed for plant disease diagnosis and resource management, namely the VGG16 model, InceptionV3, and MobileNet; the PlantVillage, PlantDoc, and FieldPlant datasets are used respectively. To reduce crop losses, AI-TI integration enables early recognition of fluctuations caused by pests or diseases, allowing control and mitigation in good time. While the issues of cost and environmental variability (illumination, canopy moisture, and microclimate instability) are taken into consideration, the advancement in artificial intelligence, robotics technology, and combined technologies will offer sustainable solutions to the existing gaps.","url":"https://doi.org/10.3390/s25226844","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25226844","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.1038/s41598-024-77034-0","name":"An intelligent emulsion explosive grasping and filling system based on YOLO-SimAM-GRCNN.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-024-77034-0","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1038/s41598-024-77034-0","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.1016/j.slast.2024.100148","name":"Achieving near-zero particle generation by simplicity of design-A compliant-mechanism-based gripper for clean-room environments.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.slast.2024.100148","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1016/j.slast.2024.100148","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:33.060Z"},{"id":"doi:10.3390/s24155080","name":"Detecting Transitions from Stability to Instability in Robotic Grasping Based on Tactile Perception.","source":"pubmed","abstract":"Robots execute diverse load operations, including carrying, lifting, tilting, and moving objects, involving load changes or transfers.

Rendering clear tactile patterns is fundamental to increasing users' precision and dexterity through tactile haptic feedback during telemanipulation. Therefore, different methods have to be studied to decode the sensors' data into haptic stimuli. This work presents a telemanipulation system for plastic pipettes that consists of a Force Dimension Omega.7 haptic interface endowed with two electro-stimulation arrays and two tactile sensor arrays embedded in the 2-finger Robotiq gripper. We propose a novel approach based on convolutional neural networks (CNN) to detect the tilt of deformable objects. The CNN generates a tactile pattern based on recognized tilt data to render further electro-tactile stimuli provided to the user during the telemanipulation.

In this context, RGB image and point-cloud observations are two commonly used modalities in visual-based robotic manipulation, but each of these modalities have their own limitations. Commercial point-cloud observations often suffer from issues like sparse sampling and noisy output due to the limits of the emission-reception imaging principle. On the other hand, RGB images, while rich in texture information, lack essential depth and 3D information crucial for robotic manipulation. To mitigate these challenges, we propose an image-only robotic manipulation framework that leverages an eye-on-hand monocular camera installed on the robot's parallel gripper. By moving with the robot gripper, this camera gains the ability to actively perceive object from multiple perspectives during the manipulation process. This enables the estimation of 6D object poses, which can be utilized for manipulation. While, obtaining images from more and diverse viewpoints typically improves pose estimation, it also increases the manipulation time. To address this trade-off, we employ a reinforcement learning policy to synchronize the manipulation strategy with active perception, achieving a balance between 6D pose accuracy and manipulation efficiency.

Heretofore, research on such operations has focused on flying without any physical interaction or exerting a pushing force on a contact surface that does not involve abrupt changes in the interaction force. In this paper, we propose a human reaction time compensating haptic-based bilateral teleoperation strategy for an aerial manipulator extracting a wedged object from a static structure (i.e., plug-pulling), which incurs an abrupt decrease in the interaction force and causes additional difficulty for an aerial platform. A haptic device composed of a 4-degree-of-freedom robotic arm and a gripper is made for the teleoperation of aerial wedged object-extracting tasks, and a haptic-based teleoperation method to execute the aerial manipulator by the haptic device is introduced. We detect the extraction of the object by the estimation of the external force exerted on the aerial manipulator and generate reference trajectories for both the aerial manipulator and the haptic device after the extraction. As an example of the extraction of a wedged object, we conduct comparative plug-pulling experiments with a quadrotor-based aerial manipulator. The results validate that the proposed bilateral teleoperation method reduces the overshoot in the aerial manipulator's position and ensures fast recovery to its initial position after extracting the wedged object.","url":"https://doi.org/10.48550/arxiv.2405.01361","authors":["Byun, Jeonghyun","Eom, Dohyun","Kim, H.

ReachBot is a novel robotic concept that uses grippers at the end of deployable booms for navigation of rough terrain such as walls of caves and lava tubes. Previous studies on ReachBot have discussed the overall robot design, placement and number of deployable booms, and gripper mechanism design; however, analysis of the perception and sensing system remains underdeveloped. Because ReachBot can extend and interact with terrain over long distances on the order of several meters, a robust perception and sensing strategy is crucial to identify grasping locations and enable fully autonomous operation. This trade study focuses on developing the perception trade space and realizing such perception capabilities for a physical prototype. This work includes analysis of: (1) multiple-range sensing strategies for ReachBot, (2) sensor technologies for subsurface climbing robotics, (3) criteria for sensor evaluation, (4) positions and modalities of sensors on ReachBot, and (5) map representations of grasping locations. From our analysis, we identify the overall perception strategy and hardware configuration for a fully-instrumented case study mission to a Martian lava tube, and identify specific sensors for a hardware prototype. The final result of our trade study is a system design conducive to benchtop testing and prototype hardware development.","url":"https://doi.org/10.48550/arxiv.2312.09302","authors":["Di, Julia"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.48550/arxiv.2312.09302","addedAt":"2026-08-31T06:34:31.426Z","updatedAt":"2026-08-31T06:34:31.426Z"},{"id":"doi:10.48550/arxiv.2402.18650","name":"The Grasp Reset Mechanism: An Automated Apparatus for Conducting Grasping Trials","source":"datacite","abstract":"Advancing robotic grasping and manipulation requires the ability to test algorithms and/or train learning models on large numbers of grasps.

A key limitation to their wider adoption is their inability to grasp larger payloads due to objects slipping out of grasps. We have overcome this limitation by introducing a torsionally rigid strain limiting layer (TRL). This reduces out-of-plane bending while maintaining the gripper's softness and in-plane flexibility. We characterize the design space of the strain limiting layer for a Pneu-net gripper using simulation and experiment and map bending angle and relative grip strength. We found that the use of our TRL reduced out-of-plane bending by up to 97.7% in testing compared to a benchmark Pneu-net gripper from the Soft Robotics Toolkit. We demonstrate a lifting capacity of 5kg when loading using the TRL. We also see a relative improvement in peak grip force of 3N and stiffness of 1200N/m compared to 1N and 150N/m for a Pneu-net gripper without our TRL at equal pressures. Finally, we test the TRL gripper on a suite of six YCB objects above the demonstrated capability of a traditional Pneu-net gripper.

Despite numerous attempts by researchers to address these via approaches involving robot perception and control, there has been a relatively limited interest in resolving it through the co-development of robot hardware. Consequently, the majority of studies employ off-the-shelf grippers in conjunction with dual robot arms to enable bimanual manipulation and high dexterity. However, this dual-arm system increases the overall cost of the robotic system as well as its control complexity in order to tackle robot collisions and other robot coordination issues. As an alternative approach, we propose to enable bimanual cloth manipulation using a single robot arm via novel end effector design -- sharing dexterity skills between manipulator and gripper rather than relying entirely on robot arm coordination. To this end, we introduce a new gripper, called G.O.G., based on a gripper-on-gripper structure where the first gripper independently regulates the span, up to 500mm, between its fingers which are in turn also grippers. These finger grippers consist of a variable friction module that enables two grasping modes: firm and sliding grasps. Household item and cloth object benchmarks are employed to evaluate the performance of the proposed design, encompassing both experiments on the gripper design itself and on cloth manipulation. Experimental results demonstrate the potential of the introduced ideas to undertake a range of bimanual cloth manipulation tasks with a single robot arm.

(Research purpose) The research purpose is determining the influence of the gripper design and its operating modes on the damage to the apple fruit and developing a methodology for assessing damage to apple fruit during robotic removal. (Materials and methods) A study was conducted using an experimental stand, which includes a laboratory installation to simulate the operation of a manipulator for harvesting fruits, a robotic gripper with an electric drive, which is mounted on a laboratory installation. Fruit samples were subjected to spectral scanning using an OCF hyperspectral camera after fruit removal using robotic capture. The obtained spectral data were processed using specialized Gelion software for subsequent analysis and quantitative assessment of the damage to the fruits. (Results and discussion). The dependence of the capture parameters on the damage to the fruits was determined on the basis of experimental data. We have developed a methodology for assessing the damage to apple fruits. (Conclusions). We conducted laboratory tests of a three-fingered robotic grip, determined the optimal parameters: compression force, distance to the fetus, at which minimal damage to the fruit is ensured during robotic removal.

Inspired by this mechanism, we designed a capacitive three-dimensional force flexible tactile sensor composed of a hollow hemisphere and a hollow cylinder. The device was fabricated using 3D printing combined with a Layer-By-Layer assembly process. For normal forces, the sensor achieved sensitivities of approximately 0.66 N -1 in the 0-1 N range and 0.15 N -1 in the 2-10 N range. For tangential forces, the four symmetrically distributed electrodes exhibited opposite monotonic capacitance variation trends. The sensor exhibited a force resolution of 0.02 N, a lower detection limit of 0.04 N, a hysteresis error as low as 3.5%, and a response/recovery time of up to 50 ms under a 0-10 N load. Moreover, the device demonstrated good stability under 1000 load-unload cycles and over a temperature range from 20 &#xb0;C to 100 &#xb0;C. Its utility was further validated through multi-scenario applications, including game controller manipulation, gripper-based object recognition, Morse code and Huffman coding transmission, as well as multi-joint human motion detection. These results demonstrate that the proposed bioinspired sensor offers a promising solution for flexible force sensing, human-machine interaction, and wearable health

This includes formulation and process development of a new drug product, which traditionally requires extensive resources, often leading to suboptimal outcomes. These development processes must adapt to follow the advances in drug discovery and clinical research and ultimately shorten timelines while ensuring product quality and safety. In this work, we present an integrated platform for tablet formulation and process development that couples a digital formulator, an in-silico optimisation tool using a predictive material-to-tablet model, with a self-driving tableting data factory, which applies Bayesian optimisation within an automated, fully integrated per-tablet manufacturing to testing workflow.

However, both the accuracy and the reliability of their measurements are influenced by operating conditions and target properties. These aspects are not fully investigated in the manufacturer's datasheet, yet they play a crucial role in downstream robotic tasks. To address this gap, we mounted three VL53L5CX sensors, an Ambient Light Sensor, and a thermistor on a robotic manipulator in a controlled laboratory setup and executed a series of experiments to characterise sensor performance. Specifically, experiments were conducted to quantify sensor drift over time, the influence of ambient illumination under three office lighting conditions, within-frame beam variability, depth accuracy over the 20-800 mm range for different materials, orientation sensitivity at different distances, and an empirical signal-to-noise ratio. The results reveal a transient warm-up effect at startup, after which measurements stabilise, a near-linear range-dependent bias with substantially larger uncertainty for dark targets, limited within-frame variability, and an invalid measurement rate consistently below 10%. Overall, the VL53L5CX provides repeatable measurements, and the findings of this work can be leveraged to derive more faithful sensor models, apply range bias correction, and broaden the range of robotic applications.","url":"https://doi.org/10.3390/s26051639","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26051639","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.3390/s26010297","name":"Adaptive Non-Singular Fast Terminal Sliding Mode Trajectory Tracking Control for Robotic Manipulator with Novel Configuration Based on TD3 Deep Reinforcement Learning and Nonlinear Disturbance Observer.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26010297","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26010297","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1002/advs.202509928","name":"Artificial Tactile Perception System for Exploring Internal and External Features of Objects via Time-Frequency Features.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/advs.202509928","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202509928","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1002/advs.202512680","name":"Biohybrid Tendons Enhance the Power-to-Weight Ratio and Modularity of Muscle-Powered Robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/advs.202512680","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202512680","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1038/s41378-026-01292-3","name":"Fingertip-scale six-axis tactile interface with high-precision force sensing and position localization for dexterous human-machine interactions.","source":"pubmed","abstract":"Developing microsystem-based tactile sensors that can simultaneously decode multidirectional forces and precise contact locations remains a formidable challenge, limiting robotic dexterity and human-machine interaction. To bridge this gap, we present HexaTouch, a fingertip-scale (15&#x2009;&#xd7;&#x2009;15&#x2009;&#xd7;&#x2009;8&#x2009;mm) sensor that synergizes the deformation-encoding principle of vision-based sensors with the miniaturization and rapid response of capacitive sensing. The core is a bioinspired bilayer elastomer monolithically incorporating a graded micropillar array, which creates spatially heterogeneous stiffness to enhance sensitivity and load tolerance while generating rich deformation patterns in response to mechanical stimuli. These local deformations are directly transduced into high-resolution capacitive images via a dense capacitive micro-array. A dedicated machine learning framework decodes these images into six-axis force/torque vectors (Fx, Fy, Fz, Mx, My, Mz) and three-dimensional contact coordinates (x, y, z). Experimental results demonstrate exceptional performance, with force measurement errors under 1.6%, contact localization precision of up to 0.1&#x2009;mm, and inference latency of only 1.5&#x2009;ms. The system maintains high stability across 0-40&#x2009;&#xb0;C and 40-90% relative humidity, with mechanical robustness confirmed through 10-day cumulative cyclic loading tests. The versatility of this sensing system is further validated through extensive applications, including dexterous grasping with stability assessment, precise peg-in-hole assembly under misalignment, and intuitive human-machine interaction in drone flight control and virtual gaming. HexaTouch therefore provides a robust, adaptable micro-tactile sensing platform that significantly advances robotic manipulation and environmental interaction.","url":"https://doi.org/10.1038/s41378-026-01292-3","authors":["Song Y","Wang J","Li Z","Hu W","Qiu Y","Tian Y","Zhao P","Liu A","Wu H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41378-026-01292-3","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1038/s41378-026-01338-6","name":"Universal bioinspired adhesives for arbitrary unknown surfaces toward dexterous robotic manipulation.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41378-026-01338-6","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41378-026-01338-6","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.3390/s26041313","name":"FEGW-YOLO: A Feature-Complexity-Guided Lightweight Framework for Real-Time Multi-Crop Detection with Advanced Sensing Integration on Edge Devices.","source":"europepmc","abstract":"Real-time object detection on resource-constrained edge devices remains a critical challenge in precision agriculture and autonomous systems, particularly when integrating advanced multi-modal sensors (RGB-D, thermal, hyperspectral). This paper introduces FEGW-YOLO, a lightweight detection framework explicitly designed to bridge the efficiency-accuracy gap for fine-grained visual perception on edge hardware while maintaining compatibility with multiple sensor modalities. The core innovation is a Feature Complexity Descriptor (FCD) metric that enables adaptive, layer-wise compression based on the information-bearing capacity of network features. This compression-guided approach is coupled with (1) Feature Engineering-driven Ghost Convolution (FEG-Conv) for parameter reduction, (2) Efficient Multi-Scale Attention (EMA) for compensating compression-induced information loss, and (3) Wise-IoU loss for improved localization in dense, occluded scenes. The framework follows a principled \"Compress, Compensate, and Refine\" philosophy that treats compression and compensation as co-designed objectives rather than isolated knobs. Extensive experiments on a custom strawberry dataset (11,752 annotated instances) and cross-crop validation on apples, tomatoes, and grapes demonstrate that FEGW-YOLO achieves 95.1% mAP@0.5 while reducing model parameters by 54.7% and computational cost (GFLOPs) by 53.5% compared to a strong YOLO-Agri baseline. Real-time inference on NVIDIA Jetson Xavier achieves 38 FPS at 12.3 W, enabling 40+ hours of continuous operation on typical agricultural robotic platforms. Multi-modal fusion experiments with RGB-D sensors demonstrate that the lightweight architecture leaves sufficient computational headroom for parallel processing of depth and visual data, a capability essential for practical advanced sensing systems. Field deployment in commercial strawberry greenhouses validates an 87.3% harvesting success rate with a 2.1% fruit damage rate, demonstrating feasibility for autonomous systems. The proposed framework advances the state-of-the-art in efficient agricultural sensing by introducing a principled metric-guided compression strategy, comprehensive multi-modal sensor integration, and empirical validation across diverse crop types and real-world deployment scenarios. This work bridges the gap between laboratory research and practical edge deployment of advanced sensing systems, with direct relevance to autonomous harvesting, precision monitoring, and other resource-constrained agricultural applications.","url":"https://doi.org/10.3390/s26041313","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26041313","addedAt":"2026-08-31T06:34:31.726Z","updatedAt":"2026-08-31T06:34:33.304Z"},{"id":"doi:10.1002/adma.202516809","name":"Autonomous

The effect of carbon nanoparticle (CN) incorporation on the electrostatic discharge properties of SLA printed rubber composites was thoroughly investigated to evaluate the feasibility of SLA in fabricating functional grippers with appropriate ESD performance. The results revealed that the rubber resin with 0.03 wt.% CN (0.03 CN) exhibited ideal resistivity (9.83 × 10 7 Ohms), tensile strength (1.3 MPa), and minimal dimensional deviations. From TGA results, it was found that the onset temperature of 3D printed rubber composites decreased with the addition of CN particles, which is associated with the enhancement of thermal conductivity of the composites. This study demonstrated that SLA can successfully fabricate soft ESD materials, offering a promising solution for 3D‐printed grippers in robotic arm applications, where controlled electrostatic properties are essential for safe and reliable operation.","url":"https://doi.org/10.1002/app.71098","authors":["Abdul Rehman","Iman Firdaus Bin Ismail","Mohamad Riduwan Bin Ramli","Chia Siang Kok","Lim Xin Yi","Raa Khimi Shuib"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-30T04:00:42Z","doi":"10.1002/app.71098","addedAt":"2026-08-31T06:34:32.659Z","updatedAt":"2026-08-31T06:34:32.659Z"},{"id":"doi:10.14743/apem2026.1.565","name":"Numerical modeling and experimental validation of an adaptive pneumatic gripper for collaborative robotic palletizing","source":"crossref","abstract":"This paper presents the development and experimental validation of an adaptive pneumatic gripper for collaborative robotic palletizing of packages with varying mass and surface characteristics. The main objective is to determine the optimal gripping-force and minimum operating pressure required to ensure stable and safe handling without slippage. A dynamic mathematical model was developed, incorporating the effects of package mass, friction coefficient, contact surface area, and inertial forces during manipulation. Numerical analysis was performed for different friction conditions (μ = 0.30-0.90) and contact configurations, enabling the determination of the minimum required gripping-forces and corresponding operating pressures. Experimental validation was conducted on a real industrial system with a collaborative robot. The results show a linear relationship between pressure and gripping-force, described by F = 22.152 p − 17.535, with a high correlation coefficient (R2 ≈ 0.998). The maximum experimentally obtained gripping-force was approximately 70-75 N at a pressure of around 4 bar. Quantitative deviations between numerical and experimental results (65-75 %) were observed and corrected by introducing a calibration factor (kcorr ≈ 0.30). The proposed model and experimental system enable reliable optimization of gripping-force and improve manipulation stability under real industrial conditions.

The gripper incorporates a four-bar mechanism for accurate finger bending and a reconfigurable design to change the relative positions between the fingers and palm, enabling precise and adaptable object grasping. This 5-Degree-of-Freedom (DOF) soft gripper can facilitate dexterous manipulation of objects with diverse shapes and stiffness and is beneficial to the safe and efficient grasping of delicate objects. An array of Force Sensitive Resistor (FSR) sensors is embedded within each robotic fingertip to serve as the tactile skin, enabling the robot to perceive contact information during manipulation. Moreover, we implemented a threshold-based tactile perception approach to enable reliable grasping without accidental slip or excessive force. To verify the effectiveness of the TacFR-Gripper, we provide detailed workspace analysis to evaluate its grasping performance and conducted three experiments, including (i) assessing the grasp success rate across various everyday objects through different finger configurations, (ii) verifying the effectiveness of tactile skin with different control strategies in grasping, and (iii) evaluating the in-hand manipulation capabilities through object pose control. The experimental results indicate that the TacFR-Gripper can grasp a wide range of complex-shaped objects with a high success rate and deliver dexterous in-hand manipulation.

Traditional rice planting methods, typically labor-intensive and prone to inconsistencies, can be enhanced through the integration of mechatronic systems, providing precise and efficient handling of rice seedlings. This study investigates the design, implementation, and optimization of a gripper system specifically tailored for rice planting, leveraging the context of competitive robotics to drive innovation. The gripper technology, a cornerstone of agricultural robotics, must achieve a delicate balance between precision and gentleness to handle fragile seedlings without causing damage. This involves the convergence of mechanical engineering, materials science, and advanced control systems to replicate the dexterity and sensitivity of human hands.

However, due to limitations in gripper performance, manual labor is still required in many manufacturing processes, especially when handling different objects. This paper proposes a classification of grippers used in the industrial field and analyzes the characteristics of each gripper category. The effectiveness of gripping and handling objects depends on the type of gripper used, making it challenging to find a gripper that can handle a wider range of objects beyond the typical boundaries. To address this issue, we describe two universal grippers developed by KIMM: the Impactive-type universal gripper and the Astrictivetype universal gripper. We also discuss the limitations of each gripper as discovered during their implementation in industrial applications and present research on overcoming these limitations. Additionally, we introduce two types of hybrid universal grippers as possible solutions to cover a broader range of fields. By analyzing these grippers, we provide predictions for the future development of grippers, which align with KIMM's ongoing research and development efforts.","url":"https://doi.org/10.57062/ijpem-st.2024.00087","authors":["Sung-Hyuk Song","Yong-Sin Seo","Jae-Young Lee","Min-jun Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-08T23:54:23Z","doi":"10.57062/ijpem-st.2024.00087","addedAt":"2026-08-31T06:34:33.059Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.1007/978-3-031-68275-9_39","name":"Inverted Operation Gripper for Robot Fabrication","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-031-68275-9_39","authors":["Karl Ahlund","Christopher Robeller"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-29T05:02:27Z","doi":"10.1007/978-3-031-68275-9_39","addedAt":"2026-08-31T06:34:33.059Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.3390/proceedings2024107024","name":"Pneumatic Prehensile Gripper for Slender Objects with Embedded Fiber Reinforcement Structures","source":"crossref","abstract":"","url":"https://doi.org/10.3390/proceedings2024107024","authors":["Zhonghua Guo","Mohammad Hossein Movahedi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-22T06:23:27Z","doi":"10.3390/proceedings2024107024","addedAt":"2026-08-31T06:34:33.059Z","updatedAt":"2026-08-31T06:34:33.059Z"},{"id":"doi:10.1088/2631-8695/ae9901/v2/review1","name":"Review for \"Structural Optimization and Experimental Analysis of Vortex Gripper for Breathable Garment Pieces\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/2631-8695/ae9901/v2/review1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-13T21:07:53Z","doi":"10.1088/2631-8695/ae9901/v2/review1","addedAt":"2026-08-31T06:34:33.302Z","updatedAt":"2026-08-31T06:34:35.122Z"},{"id":"doi:10.1109/access.2026.3676116","name":"Model-Based Grasp Optimization of a Soft Fin-Ray Robotic Gripper Using Physics-Informed Beam Bending and Contact Metrics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/access.2026.3676116","authors":["Dario Stuhne","Goran Vasiljevic"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-23T20:09:20Z","doi":"10.1109/access.2026.3676116","addedAt":"2026-08-31T06:34:33.302Z","updatedAt":"2026-08-31T06:34:33.302Z"},{"id":"doi:10.1088/2631-8695/ae9901/v1/review2","name":"Review for \"Structural Optimization and Experimental Analysis of Vortex Gripper for Breathable Garment Pieces\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/2631-8695/ae9901/v1/review2","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-13T21:07:53Z","doi":"10.1088/2631-8695/ae9901/v1/review2","addedAt":"2026-08-31T06:34:33.302Z","updatedAt":"2026-08-31T06:34:35.623Z"},{"id":"doi:10.1109/southeastcon63549.2026.11476183","name":"ROS 2 Hardware Interface for the PincOpen Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1109/southeastcon63549.2026.11476183","authors":["Darryle K.

However, developing practical grippers while balancing compliance, structural rigidity, and controlled mechanical behavior remains a challenge. This work presents a multimaterial robotic gripper primarily fabricated via fused filament fabrication, integrating thermoplastic polyurethane (TPU), and conductive polylactic acid (c‐PLA) in a functionally layered structure. TPU serves as soft interfaces for grasped objects, compliant spring elements for passive finger restoration and a flexible housing for embedded sensing components. c‐PLA provides the rigid backbone and forms the basis for variable stiffness joints, where Joule‐heating is applied via embedded nichrome wires. Integrated thermistors enable the gripper to self‐monitor joint temperatures, facilitating active regulation of stiffness in real time. To enhance thermal response, a detachable additively manufactured cooling channel directs forced convection across heated joints, significantly reducing cooling times. The gripper achieves multiple gripping configurations using a single cable‐tendon system, with experimental results demonstrating reliable adaptation to objects of varying size, shape, and rigidity. This work outlines a practical, accessible approach to creating selectively stiffening, self‐monitoring grippers, offering a versatile platform for adaptive manipulation in robotic automation.","url":"https://doi.org/10.1002/adrr.202500054","authors":["Daniel Jee Seng Goh","Guo Liang Goh","Selvanther Sivarajan","Van Pho Nguyen","Wai Yee Yeong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-23T05:44:51Z","doi":"10.1002/adrr.202500054","addedAt":"2026-08-31T06:34:33.303Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.1088/2631-8695/ae9901/v1/decision1","name":"Decision letter for \"Structural Optimization and Experimental Analysis of Vortex Gripper for Breathable Garment Pieces\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/2631-8695/ae9901/v1/decision1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-13T21:07:53Z","doi":"10.1088/2631-8695/ae9901/v1/decision1","addedAt":"2026-08-31T06:34:33.303Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.3390/agriculture16131393","name":"Configuration Optimization and Field Validation of a Multi-Joint Pneumatic Soft Gripper for Robotic Apple Harvesting","source":"crossref","abstract":"Driven by orchard labor shortages and rising demand for intelligent harvesting, automated apple picking requires a balance between conformal enveloping and slip-resistant stability. To reduce damage and slippage caused by fragile skins, variable morphologies, and motion disturbances, this study proposes a multi-joint pneumatic flexible apple-picking hand with adjustable circumferential configuration. Based on structural configuration determining grasping stability, six apple-morphology-based finger-base supports were designed. Parametric analysis of soft gripper cavities identified an isosceles trapezoidal profile as the best configuration. Using the Yeoh constitutive model, an equivalent joint model for conformal gripping was developed, and genetic algorithm (GA) optimization selected the four-joint design as the preferred configuration. Static finite element simulations determined an operating pressure of 20.32 kPa. Grasping stability was quantified by relative slip displacement in rigid–flexible coupled dynamic simulations. Among the tested support configurations within 60–110°, the 90° bracket produced the most stable slip response under vertical and horizontal disturbances. Thin-film pressure tests showed an asymmetric but stable three-finger load-sharing pattern. Field trials in a high-density dwarf spindle orchard achieved an 83.98% harvesting success rate. After 72 h of cold storage, no obvious surface browning, epidermal abrasion, or compression marks were observed during visual inspection. This assessment was limited to visible external damage and did not include quantitative evaluation of internal bruising, firmness degradation, flesh browning, or long-term storage quality. These results demonstrate stable grasping performance and low visible external damage under the tested conditions.","url":"https://doi.org/10.3390/agriculture16131393","authors":["Le Kang","Jiayu Yu","Yuhang Du","Meng Tian","Jiaxing Shi","Yafeng Li","Guodong Lang","Pan Fan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-29T00:54:42Z","doi":"10.3390/agriculture16131393","addedAt":"2026-08-31T06:34:33.303Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.1109/aim65483.2026.11658082","name":"Passive rotational gripper equipped with tactile image sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim65483.2026.11658082","authors":["Kento Nomura","Kazuhiro Shimonomura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-25T19:12:25Z","doi":"10.1109/aim65483.2026.11658082","addedAt":"2026-08-31T06:34:33.303Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1007/978-981-95-6825-3_11","name":"A Novel Three-Finger Robotic Gripper with Flexible Belt Mechanism for Precision and Compliant Grasping","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-95-6825-3_11","authors":["Hongyi Chen","Yicheng Chang","Puxin Yan","Minghao Wu","Mengtang Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-20T08:35:37Z","doi":"10.1007/978-981-95-6825-3_11","addedAt":"2026-08-31T06:34:33.303Z","updatedAt":"2026-08-31T06:34:33.303Z"},{"id":"doi:10.1109/eras69098.2026.11564266","name":"Reliability Screening for Magnetic Gripper Interference in Autonomous Tack Welding","source":"crossref","abstract":"","url":"https://doi.org/10.1109/eras69098.2026.11564266","authors":["P.

In this work, a poly(ionic liquid) (PIL) electrode with an ultralow elastic modulus of 3.4 kPa and rapid self-healing within 10 s in ambient and underwater conditions is achieved through ionic interaction regulation.

However, very few of these robots are capable of actively engaging with humans and undertaking physical manipulation tasks. This limitation is largely attributed to the absence of tools that can realistically simulate physical interactions, especially the contact mechanisms between a robotic gripper and a human body. In this letter, we aim to address key limitations in current developments towards robotic casualty manipulation. Firstly, we present an integrative simulation framework for casualty manipulation. We adapt a finite element method (FEM) tool into the grasping and manipulation scenario, and the developed framework can provide accurate biomechanical reactions resulting from manipulation. Secondly, we conduct a detailed assessment of grasping stability during casualty grasping and manipulation simulations. To validate the necessity and superior performance of the proposed high-fidelity simulation framework, we conducted a qualitative and quantitative comparison of grasping stability analyses between the proposed framework and the state-of-the-art multi-body physics simulations. Through these efforts, we have taken the first step towards a feasible solution for robotic casualty manipulation.","url":"https://doi.org/10.48550/arxiv.2404.03741","authors":["Zhao, Qianwen","Roy, Rajarshi","Spurlock, Chad","Lister, Kevin","Wang, Long"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.48550/arxiv.2404.03741","addedAt":"2026-08-31T06:34:34.732Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.48550/arxiv.2503.20820","name":"Benchmarking Multi-Object Grasping","source":"datacite","abstract":"In this work, we describe a multi-object grasping benchmark to evaluate the grasping and manipulation capabilities of robotic systems in both pile and surface scenarios.

The robot is constructed with PLA material using a known design framework; it is not unique but reliable enough to form a base for testing and exploration. The manipulator is fitted with servo motors for the movement of the joints, and the gripper serves as an end effector, which aids in holding objects of several shapes. The Arduino Uno controls the servo motors to provide precise and speedy movements. An overhead camera takes real-time pictures of the environment to enable the manipulator to identify objects more efficiently. These images are then processed to identify and locate objects correctly within the manipulator's workspace. The integration of the camera with the robotic system allows for dynamism in adjustments and decisions related to grasping tasks in real-time. In this paper, research is done to comprehensively study the performance of the manipulator in detecting and grasping objects. Extensive testing was conducted to test efficiency, accuracy, and reliability under different scenarios.

A robot needs to apply the right amount of force to quickly and confidently grasp the objects so that it can perform the required task. Although some methods have been proposed to tackle this issue, performance assessment is still a problem for directly measuring object property changes and possible damage. To fill the gap, a new concept is introduced in this paper to assess compliant robotic grasping using instrumented objects. A proof-of-concept design is proposed to measure the force applied on a cuboid object from a first-object perspective. The design can detect multiple contact locations and applied forces on its surface by using multiple embedded 3D Hall sensors to detect deformation relative to embedded magnets. The contact estimation is achieved by interpreting the Hall-effect signals using neural networks. In comprehensive experiments, the design achieved good performance in estimating contacts from each single face of the cuboid and decent performance in detecting contacts from multiple faces when being used to evaluate grasping from a parallel jaw gripper, demonstrating the effectiveness of the design and the feasibility of the concept.","url":"https://doi.org/10.48550/arxiv.2312.14466","authors":["Knopke, Maceon","Zhu, Liguo","Corke, Peter","Zhang, Fangyi"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.48550/arxiv.2312.14466","addedAt":"2026-08-31T06:34:34.732Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.18720/spbpu/3/2019/vr/vr19-751","name":"Разработка Ð·Ð°Ñ Ð²Ð°Ñ‚Ð½Ð¾Ð³Ð¾ устройства для манипулятора с возможностью использования сменного Ð·Ð°Ñ Ð²Ð°Ñ‚Ñ‹Ð²Ð°ÐµÐ¼Ð¾Ð³Ð¾ инструмента","source":"datacite","abstract":"Целью работы является разработка манипулятора с возможностью использования сменных инструментальных модулей на малогабаритной робототехнической платформе.

However, wind turbine blades (WTB) are subjected to failure due to many loading effects such as aerodynamic, gravity and centrifugal loads and operation in harsh environments such as ultraviolet (UV) radiation, ice, hail, temperature variation, dirt, and salt. As a result, the blades suffer different types of damage. Consequently, a periodic inspection process is required to detect and repair defects before a catastrophic failure happens. This thesis presents a literature review of wall climbing robots to identify the most appropriate locomotion and adhesion method to use for a WT climbing machine that can take a large payload of non-destructive testing (NDT) sensors up to a blade and deploy them with scanning arms. A review of wind turbine blade construction, various loading effects on blades and types of damage in blades is followed by a review of the NDT techniques used for inspecting WTB. The above review determines the design requirements to achieve the aim of the current research which is to design a low-cost and reliable mobile robot which will be able to climb the WT tower and subsequently scan the blade surface to perform the inspection using various sensors to identify and classify damages. This robot system should be able to access all the critical areas of the blade structure in a stable and secure way. It should be stable enough to allow the various test sensors to scan the blade structure in the shortest possible time. The thesis describes the development of a tower climbing robot that uses magnetic adhesion to adhere to the WT. As a preliminary study, a simulation model is developed using COMSOL Multiphysics to simulate the magnetic adhesion force while climbing the tower. A test rig is designed and fabricated to measure the magnetic adhesion force experimentally to validate the simulation model. The response surface methodology (RSM) using Box-Behnken design (BBD) is used to design and perform experiments to optimise different independent variables i.e. air gap, the distance between magnets in an array and backplate (yoke) thickness that affect the magnetic adhesion force. A scaled-down prototype magnetic adhesion climbing robot has been designed and constructed for wind turbine blade inspection. The robot is 0.29 m long with two 1.0 m long arms, weighs 10.0 kg and can carry a maximum 2.0 kg payload of NDT sensors. Optimum design of a magnetic adhesion mechanism has been developed for the climbing robot prototype that maximises the magnetic adhesion force. The robot is equipped with two arms that can be extended by one meter to come close to the blade for inspection. Each arm is equipped with a gripper that can hold an inspection tool of weight up to one kilogram. A scaled-down wind turbine has been modelled using SolidWorks and a portion of it constructed to experimentally test the scaled-down climbing robot. To scale up the robot prototype for operation on a normal sized wind turbine, a 100 m tall wind turbine with three 76 m long blades has been modelled and the prototype robot scaled up based on these dimensions. The scaled-up robot is 3.0 m long, weighs 1135 kg and has two 10 m long arms. Static stress analysis and flow simulation have been carried out to check the durability of the scaled-up robot while climbing the wind turbine tower. The procedure for scaling up the adhesion mechanism to achieve equilibrium of the robot has been introduced based on the reaction force concluded from the static stress and flow simulation study. As a result, the maximum payload that each arm can carry has been calculated for both the scaled-down prototype (1 kg) and the scaled-up design (50 kg). This concludes the utility and robustness of the wall climbing robot as a robotic solution for wind turbine blade inspection.","url":"https://doi.org/10.18744/lsbu.92v70","authors":["Sahbel, Anwar Magdy Mohamed Zaky"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.18744/lsbu.92v70","addedAt":"2026-08-31T06:34:34.732Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.48550/arxiv.2209.06074","name":"Bimanual crop manipulation for human-inspired robotic harvesting","source":"datacite","abstract":"Most existing robotic harvesters utilize a unimanual approach; a single arm grasps the crop and detaches it, either via a detachment movement, or by cutting its stem with a specially designed gripper/cutter end-effector. However, such unimanual solutions cannot be applied for sensitive crops and cluttered environments like grapes and a vineyard where obstacles may occlude the stem and leave no space for the cutter's placement. In such cases, the solution would require a bimanual robot in order to visually unveil the stem and manipulate the grasped crop to create cutting affordances which is similar to the practice used by humans. In this work, a dual-arm coordinated motion control methodology for reaching a stem pre-cut state is proposed. The camera equipped arm with the cutter is reaching the stem, unveiling it as much as possible, while the second arm is moving the grasped crop towards the surrounding free-space to facilitate its stem cutting.

However, when it comes to grasping highly flexible objects such as textiles, we face the dual problem: it is the object that will adapt to the shape of the hand or gripper. In this context, the classic grasp analysis or grasping taxonomies are not suitable for describing textile objects grasps. This work proposes a novel definition of textile object grasps that abstracts from the robotic embodiment or hand shape and recovers concepts from the early neuroscience literature on hand prehension skills. This framework enables us to identify what grasps have been used in literature until now to perform robotic cloth manipulation, and allows for a precise definition of all the tasks that have been tackled in terms of manipulation primitives based on regrasps. In addition, we also review what grippers have been used. Our analysis shows how the vast majority of cloth manipulations have relied only on one type of grasp, and at the same time we identify several tasks that need more variety of grasp types to be executed successfully. Our framework is generic, provides a classification of cloth manipulation primitives and can inspire gripper design and benchmark construction for cloth manipulation.","url":"https://doi.org/10.48550/arxiv.1906.08202","authors":["Borràs, Júlia","Alenya, Guillem","Torras, Carme"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.48550/arxiv.1906.08202","addedAt":"2026-08-31T06:34:34.732Z","updatedAt":"2026-08-31T06:34:34.732Z"},{"id":"doi:10.26262/heal.auth.ir.129031","name":"Χειρισμός Ρομποτικής Πλατφόρμας και Ρομποτικού Βραχίονα με Παρακολούθηση των Χεριών και Χρήση Χειρονομιών","source":"datacite","abstract":"Η παρούσα πτυχιακή εργασία πραγματεύεται το θέμα της αλληλεπίδρασης ανθρώπου - ρομπότ και προχωρά στον σχεδιασμό, την ανάπτυξη και την υλοποίηση ενός πρωτότυπου συστήματος χειρισμού μιας ρομποτικής πλατφόρμας που διαθέτει ρομποτικό βραχίονα και αρπάγη.

Detecting and obtaining the characteristics in dwelling lumps embedded in a soft tissue and safe removing and handling of detected lumps is needed in surgery. Also in industry, grasping and handling an object without damaging in a place where it is not possible to access a human operator is very important. In this paper, a method for object handling is presented. It is based on the use of an intelligent gripper to detect the object stiffness and then setting a programmable force for grasping the object to move it. The main components of this system includes sensors (sensors for measuring force and displacement), electrical (electrical and electronic circuits, tactile data processing and force control system), mechanical (gripper mechanism and driving system for the gripper) and the display unit. The system uses a rotary potentiometer for measuring gripper displacement.

Detecting and obtaining the characteristics in dwelling lumps embedded in a soft tissue and safe removing and handling of detected lumps is needed in surgery. Also in industry, grasping and handling an object without damaging in a place where it is not possible to access a human operator is very important. In this paper, a method for object handling is presented. It is based on the use of an intelligent gripper to detect the object stiffness and then setting a programmable force for grasping the object to move it. The main components of this system includes sensors (sensors for measuring force and displacement), electrical (electrical and electronic circuits, tactile data processing and force control system), mechanical (gripper mechanism and driving system for the gripper) and the display unit. The system uses a rotary potentiometer for measuring gripper displacement.

In view of the excellent tree-climbing ability of cats, the cat-paw robot gripper in this paper is different from the traditional tree-climbing robot, which is suitable for the complex tree environment. This is also an inspiration for the paw design of the quadruped robot to complete the climbing action.

An intelligent robot is the one which interact with the environment and can take the decisions itself. Domestic robots can also provide assistance to physically disabled or elder people in their day to day life. Pressing the demands of enhanced productivity has necessitated the deployment of robot to automate tasks (Baizid et al., 2015). A manipulator can be geared with end-effector to complete variety of tasks. Robotic grippers are used in agriculture, food processing industry, packaging of food, palletizing of boxes and many more. Grippers are the device that enables robots to grasp and grip objects. The designing of end effector should be done by considering its specific application in industry. On comparison of gripper with human hand, a robot’s gripper is very bounded in terms of mechanical movement, practical service and general applications. To use the full ability of robotic technology, the gripper must be designed more of a like human hand. This paper attempts to describe the different technologies of Robotic gripper which help the people which would be a Businessman as well as common people or Industrialist. The main target of this paper is to contribute some information on different on robotic grippers, since selection of gripper plays a fundamental part in robot’s productivity and performance.","url":"https://doi.org/10.35940/ijaent.c7232.0511523","authors":["Meet Chitroda","Dr. Bhumeshwar K.

Growing interest has also been in using integrated servo motors for these applications, which would benefit from the integrated nature of the motor, feedback device, and drive electronics in a single package. This paper introduces a methodology for trajectory planning for the reciprocating motion for a linear motion device. The methodology can be implemented on any device, and a simplified version can be applied to the control software for integrated servo motors. The approach develops motion trajectories, such as triangular or trapezoidal, using a dynamic model of the device and the motor’s torque–speed profile characteristics. The simplified version of the methodology was implemented using an integrated servo motor driving a ball screw stage. Tests were conducted at various motion rates and loads. The experimental results show high accuracy between the predicted and measured motion rates, particularly for rates below three cycles per second. These results suggest that the developed methodology can be a valuable tool for predicting the performance of systems that use integrated servo motors for reciprocating motion applications.","url":"https://doi.org/10.3390/machines12120934","authors":["Max Schnegas","Musa K.

For most control systems, integral action is used to overcome the reference input change and external load. However, its control performance cannot be guaranteed. State feedback control is used to dominate the pole location of the closed-loop control system. However, the system parameters determine their pole locations and may change due to uncertainties. Thus, the characteristics of the closed-loop control system are changed. Sliding mode control is used to compensate for the effect of the parameter variations and make the system invariant. The resulting system combines linear state feedback and sliding mode control to guarantee the desired performance. This shows that the proposed system can be easily applied and designed. A servo control system is used to demonstrate the performance, and simulations and experiments are carried out to evaluate the newly defined structure.

However, these motors are prone to overheating under certain internal conditions, such as temperature or supply voltage fluctuations during prolonged use. This research aims to design and apply PID control methodology to regulate Dynamixel servo motors. The research includes motor implementation using the PID method and subsequent testing with varying voltage inputs ranging from 11V to 12V. Addressing these issues involves using the Proportional Integral Derivative (PID) control method, widely recognized for its reliability in controlling motor speed. The research successfully designed Dynamixel servo motors capable of PID-controlled rotation according to predefined reference values. The motor's PID control design involved multiple trial runs - up to 5 instances - for each proportional, integral, and derivative control. The default PID parameter implementation did not match the setpoint; however, a re-tuned PID method yielded optimal results with parameter values Kp = 0.01000; Ki = 0.02703; Kd = 0.00005. Test results showed that the PID-controlled Dynamixel servomotor accurately achieved the expected angular output of 75°. In addition, tests using voltage inputs ranging from 11.00 to 12.00 volts showed stable operation without changing the servo motor's angular position before applying the PID control value, ensuring consistent motion even as the voltage drops.","url":"https://doi.org/10.59247/csol.v2i1.40","authors":["Nur Ramadhani","Alfian Ma'arif","Abdullah Çakan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-21T04:28:41Z","doi":"10.59247/csol.v2i1.40","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.1109/itecasia-pacific63159.2024.10738581","name":"Error Iterative Control Strategy for Permanent Magnet Synchronous Motor Servo System","source":"crossref","abstract":"","url":"https://doi.org/10.1109/itecasia-pacific63159.2024.10738581","authors":["Yan Zhang","Qihang Ji","Wentao Zhang","Jiaqi Wang","Kaixu Li","Yongxiang Xu","Jibin Zou"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-04T18:34:00Z","doi":"10.1109/itecasia-pacific63159.2024.10738581","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.1109/anzcc59813.2024.10432923","name":"Suppression of Adverse Effects of Transmission Clearance in Brushless DC Motor Servo Systems by Switching Compensation*","source":"crossref","abstract":"","url":"https://doi.org/10.1109/anzcc59813.2024.10432923","authors":["Dao Zhou","Yunlong Yang","Xiongjun Wu","Biao Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-20T13:45:25Z","doi":"10.1109/anzcc59813.2024.10432923","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.52447/jkte.v9i2.7473","name":"Implementasi dan Perbandingan Performansi Kontroler Proportional Integral (PI) dengan Adaptive Neuro Fuzzy Inference System (ANFIS) pada Sistem Servo Motor DC","source":"crossref","abstract":"Kesadaran masyarakat terhadap transportasi yang mempengaruhi dampak negatif dalam lingkungan, menimbulkan efek meningkatnya penggunaan mobil listrik.

This work presented the tuning of the PID/FOPID controller by the conventional Ziegler-Nichols (ZN) method and the Particle Swarm Optimization (PSO) algorithm. The PID controller is the most popular in the industry because it is simple to implement, has good computing ability, and provides a robust system. These methods are implemented on the DC servomotor system to optimize the transient responses like rise time (𝑡𝑟), settling time (𝑡𝑠), and peak overshoot (𝑀𝑝) to get a better result. The PID controller tuned by the conventional ZN method gives a longer settling time, a longer rise time, and a higher peak overshoot. The PSO algorithm is utilized to overcome the significant overshoot and considerable settling time obtained in the conventional Ziegler-Nichols method. Analyzing and comparing the MATLAB simulation results, it is observed that PSO algorithms provide a better-optimized response over the ZN method with FOPID controller in respect of less rise time (𝑡𝑟 =0.0392 sec.), less settling time (𝑡𝑠=0.0605 sec.) and peak overshoot (𝑀𝑝=1.92%). The results obtained by the proposed controller provide better reliability and better response.","url":"https://doi.org/10.24042/ijecs.v4i2.25071","authors":["Arti Saxena","Vishal R Panse","Ardian Asyhari","Rofiqul Umam","Marta Michalska-Domańska","Aparna Dixit"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-01-17T12:00:46Z","doi":"10.24042/ijecs.v4i2.25071","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.1201/9781003120018-40","name":"Servo Motor","source":"crossref","abstract":"","url":"https://doi.org/10.1201/9781003120018-40","authors":["Hossam Fattah"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-05-06T16:59:49Z","doi":"10.1201/9781003120018-40","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/compel.2006.305634","name":"Current Sense Circuit for a DC Powered Three Phase Servo Motor Controller","source":"crossref","abstract":"","url":"https://doi.org/10.1109/compel.2006.305634","authors":["Donald Fulton"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-07-21T20:51:20Z","doi":"10.1109/compel.2006.305634","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/cac59555.2023.10451696","name":"New Double Loop Control Strategy for DC Motor Position Servo System","source":"crossref","abstract":"","url":"https://doi.org/10.1109/cac59555.2023.10451696","authors":["Rongsheng Guo","Zhimei Chen","Liqin Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-03-19T18:04:17Z","doi":"10.1109/cac59555.2023.10451696","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.33387/protk.v6i2.1212","name":"Desain Kontroler Proporsional Modifikasi pada Motor Servo","source":"crossref","abstract":"","url":"https://doi.org/10.33387/protk.v6i2.1212","authors":["Abdul Hadi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-10-01T07:53:16Z","doi":"10.33387/protk.v6i2.1212","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1541/ieejias.115.1347","name":"High Performance Servo-System by Rotational Machines.

This will greatly increase the cost of the system, and the sensor with high precision is difficult to be installed. On the other hand, the sensorless method can reduce the cost, but the reliability and complexity of the algorithm is still the problems. In this paper, a new low-cost integrated position detection unit, which is composed of the integrated position sensor, signal processing hardware and software, is described. The sensor is easy to manufacture and has better precision with the help of signal processing circuit and software based on DSP. The sensor can obtain absolute rotating angle using inductance detection method, and it is originally designed and used for a 2-phase hybrid stepping motor position servo system. Even though the feedback unit is originally designed for a 2-phase hybrid stepping motor, the same unit also can be used with other types of motors.","url":"https://doi.org/10.4028/www.scientific.net/amr.383-390.1235","authors":["Shu Zhong Song","Jing Zhuo Shi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-11-25T15:05:43Z","doi":"10.4028/www.scientific.net/amr.383-390.1235","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1016/c2022-0-01449-5","name":"Parameter Estimation and Adaptive Control for Nonlinear Servo Systems","source":"crossref","abstract":"","url":"https://doi.org/10.1016/c2022-0-01449-5","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-02T13:11:44Z","doi":"10.1016/c2022-0-01449-5","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.3390/act14090459","name":"Agentic AI for Real-Time Adaptive PID Control of a Servo Motor","source":"crossref","abstract":"This study explores a novel approach of using large language models (LLMs) in the real-time Proportional–Integral–Derivative (PID) control of a physical system, the Quanser QUBE-Servo 2. We investigated whether LLMs, used with an Artificial Intelligence (AI) agent workflow platform, can participate in the live tuning of PID parameters through natural language instructions. Two AI agents were developed: a control agent that monitors the system performance and decides if tuning is necessary, and an Optimizer Agent that updates PID gains using either a guided system prompt or a self-directed free approach within a safe parameter range. The LLM integration was implemented through Python programming and Flask-based communication between the AI agents and the hardware system. Experimental results show that LLM-based tuning approaches can effectively reduce standard error metrics, such as IAE, ISE, MSE, and RMSE. This study presents one of the first implementations of real-time PID tuning powered by LLMs, and it has the potential to become a novel alternative to classical control, as well as machine learning or reinforcement learning-based approaches. The results are promising for using agentic AI in heuristic-based tuning and the control of complex physical systems, marking the shift toward more human-centered, explainable, and adaptive control engineering.","url":"https://doi.org/10.3390/act14090459","authors":["Tariq Arif","Md Rahim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-22T11:18:16Z","doi":"10.3390/act14090459","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/robot.2008.4543298","name":"Modeling and fault analysis of BLDC motor based servo actuators for manipulators","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.2008.4543298","authors":["Sewoong Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-06-16T14:43:38Z","doi":"10.1109/robot.2008.4543298","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.5120/20433-2764","name":"Controlling Servo Motor Angle by Exploiting Kinect SDK","source":"crossref","abstract":"","url":"https://doi.org/10.5120/20433-2764","authors":["Farzin Foroughi","Peng Zong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-04-28T09:07:10Z","doi":"10.5120/20433-2764","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/iecon.1989.69647","name":"Predictive learning control and application to servo system of DC motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iecon.1989.69647","authors":["H.

But, despite the advantages of the proposed servo system, it is strongly coupled, non‐linear and multivariable, where the biggest challenge lies in its tracking and synchronization control. To improve the tracking and synchronization control performance of the proposed servo system, a tracking and synchronization control strategy based on backstepping super‐twisting control and multi‐level differential coupling is presented. First, a parallel model of the dual‐motor is established. Then, backstepping and super‐twisting control algorithms are integrated while adaptively optimizing key parameters to ensure the robustness and tracking performance of each motor. After that, an angular synchronization controller with multi‐level differential coupling and backstepping super‐twisting algorithm is proposed to compensate for the synchronization error of the dual‐motor system caused by parameter uncertainty. Finally, the simulation is carried out using Simulink to verify the effectiveness of the proposed control strategy.","url":"https://doi.org/10.1049/cth2.12613","authors":["Taoyu Wang","Shiyan Sun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-01-23T03:55:04Z","doi":"10.1049/cth2.12613","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.14775/ksmpe.2024.23.12.102","name":"Analysis for Thermal Safety of Controller Integrated Servo-Motor in Tracked Military Vehicle","source":"crossref","abstract":"","url":"https://doi.org/10.14775/ksmpe.2024.23.12.102","authors":["Chi Gyeong Jun","Hong Ik Son","Seong-Ho Yun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-27T00:17:16Z","doi":"10.14775/ksmpe.2024.23.12.102","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:35.423Z"},{"id":"doi:10.4172/2168-9695.1000170","name":"Comparison of Repetitive Control Schemes for a DC Servo Motor","source":"crossref","abstract":"","url":"https://doi.org/10.4172/2168-9695.1000170","authors":["Jacob S Glower"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-02-01T01:32:12Z","doi":"10.4172/2168-9695.1000170","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/acc.2013.6579993","name":"Real-time energy-optimal trajectory generation for a servo motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/acc.2013.6579993","authors":["Yiming Zhao","Yebin Wang","Scott A.

emotional intelligence, memory architecture, and gestures to achieve empathetic humanoid robot interaction in an educational setting.","source":"europepmc","abstract":"This study investigates the integration of individual human traits into an empathetically adaptive educational robot tutor system designed to improve student engagement and learning outcomes with corresponding Engagement Vector measurements. While prior research in the field of Human-Robot Interaction (HRI) has examined the integration of the traits, such as emotional intelligence, memory-driven personalization, and non-verbal communication, by themselves, they have thus-far neglected to consider their synchronized integration into a cohesive, operational education framework. To address this gap, we customize a Multi-Modal Large Language Model (Llama 3.2 from Meta) deployed with modules for human-like traits (emotion, memory and gestures) into an AI-Agent framework. This constitutes the robot's intelligent core that mimics the human emotional system, memory architecture and gesture controller to allow the robot to behave more empathetically while recognizing and responding appropriately to the student's emotional state. It can also recall the student's past learning record and adapt its style of interaction accordingly. This allows the robot tutor to react to the student in a more sympathetic manner by delivering personalized verbal feedback synchronized with relevant gestures. Our study suggests the extent of this effect through the introduction of Engagement Vector Model which can be a benchmark for judging the quality of HRI experience. Quantitative and qualitative results demonstrate that such an empathetic responsive approach significantly improves student engagement and learning outcomes compared with a baseline humanoid robot without these human-like traits. This indicates that robot tutors with empathetic capabilities can create a more supportive, interactive learning experience that ultimately leads to better outcomes for the student.","url":"https://doi.org/10.3389/frobt.2025.1635419","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3389/frobt.2025.1635419","addedAt":"2026-08-31T06:34:35.423Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1371/journal.pone.0304085","name":"Development

Design and Control of a Biomimetic Binocular Cooperative Perception System Inspired by the Eye Gaze Mechanism.","source":"pubmed","abstract":"Research on systems that imitate the gaze function of human eyes is valuable for the development of humanoid eye intelligent perception. However, the existing systems have some limitations, including the redundancy of servo motors, a lack of camera position adjustment components, and the absence of interest-point-driven binocular cooperative motion-control strategies. In response to these challenges, a novel biomimetic binocular cooperative perception system (BBCPS) was designed and its control was realized. Inspired by the gaze mechanism of human eyes, we designed a simple and flexible biomimetic binocular cooperative perception device (BBCPD). Based on a dynamic analysis, the BBCPD was assembled according to the principle of symmetrical distribution around the center. This enhances braking performance and reduces operating energy consumption, as evidenced by the simulation results. Moreover, we crafted an initial position calibration technique that allows for the calibration and adjustment of the camera pose and servo motor zero-position, to ensure that the state of the BBCPD matches the subsequent control method. Following this, a control method for the BBCPS was developed, combining interest point detection with a motion-control strategy. Specifically, we propose a binocular interest-point extraction method based on frequency-tuned and template-matching algorithms for perceiving interest points. To move an interest point to a principal point, we present a binocular cooperative motion-control strategy. The rotation angles of servo motors were calculated based on the pixel difference between the principal point and the interest point, and PID-controlled servo motors were driven in parallel. Finally, real experiments validated the control performance of the BBCPS, demonstrating that the gaze error was less than three pixels.","url":"https://doi.org/10.3390/biomimetics9020069","authors":["Qin X","Xia X","Ge Z","Liu Y","Yue P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/biomimetics9020069","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"doi:10.1038/s41598-024-74330-7","name":"Velocity-free event-triggered control for a class of uncertain axis-motion systems with prescribed performance.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-024-74330-7","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1038/s41598-024-74330-7","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:36.400Z"},{"id":"doi:10.3390/mi16070807","name":"A Rotary Piezoelectric Electromagnetic Hybrid Energy Harvester.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi16070807","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/mi16070807","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1016/j.heliyon.2024.e26936","name":"Health assessment of an electro-hydraulic servo pump control system for servomotor based on LGA deep neural network.","source":"pubmed","abstract":"","url":"https://doi.org/10.1016/j.heliyon.2024.e26936","authors":["Wang F","Chen G","Liu K","Zhang T","Li Y","Ai C"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1016/j.heliyon.2024.e26936","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:36.400Z"},{"id":"doi:10.1523/eneuro.0038-25.2025","name":"An Open-Source Joystick Platform for Investigating Forelimb Motor Control, Auditory-Motor Integration, and Value-Based Decision-Making in Head-Fixed Mice.","source":"europepmc","abstract":"","url":"https://doi.org/10.1523/eneuro.0038-25.2025","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1523/eneuro.0038-25.2025","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:36.400Z"},{"id":"doi:10.1016/j.plaphe.2025.100085","name":"PhenoRob-F: An autonomous ground-based robot for high-throughput phenotyping of field crops.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.plaphe.2025.100085","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1016/j.plaphe.2025.100085","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.1167/tvst.13.5.2","name":"A Magnetic Actuator Device for Fully Automated Blinking in Total Bidirectional Eyelid Paralysis: First Proof of Concept in a Human Participant.","source":"europepmc","abstract":"","url":"https://doi.org/10.1167/tvst.13.5.2","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1167/tvst.13.5.2","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:36.400Z"},{"id":"doi:10.21203/rs.3.rs-5410876/v1","name":"Design and Evaluation of an Egg Sorting Machine","source":"europepmc","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-5410876/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-5410876/v1","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.1016/j.isatra.2024.01.036","name":"Fractional-order electromagnetic modeling and identification for PMSM servo system.","source":"pubmed","abstract":"An accurate electromagnetic model is essential for an optimal controller tuning of the high-performance servo system.

The influence of voltage source inverter nonlinearity, which may cause system identification error, is analyzed. An improved inverter nonlinearity model and compensation method are proposed to promote the accuracy of the model parameter identification. Compared with the existing typical electromagnetic models of the PMSM servo system, the current open-loop and closed-loop experiments prove that the proposed fractional-order electromagnetic model with time delay is more accurate for the actual physical system.

Electroencephalography (EEG) studies consistently identify two perturbation-evoked markers of cortical activity, the balance N1 and midfrontal theta power, associated with changes in body orientation and corrective actions. It remains unclear, however, whether these markers depend on the nervous system’s active control of posture or reflect a more general evaluation of unexpected sensory input. We tested this by measuring cortical and muscle activity during support-surface perturbations while systematically manipulating whether participants actively controlled posture. In Experiment 1 (n = 10), participants experienced identical perturbations while either actively balancing or being passively moved through equivalent motion. Despite large reductions in balance-correcting muscle activity during passive trials (∼30-60%), N1 and theta responses persisted with only modest amplitude reductions (∼10%). In Experiment 2 (n = 16), we created passive conditions increasingly removed from balance by varying sensory feedback (footplate + whole-body vs footplate-only motion) and motor engagement (isometric contraction vs. relaxed posture). Relaxed postures markedly suppressed muscle responses, yet cortical responses persisted, showing only modest modulation with sensory feedback (larger during footplate-only rotations) and no dependence on motor engagement. Together, these results indicate that N1 and midfrontal theta are not dependent on active postural control and persist even without matching sensory feedback or motor engagement. Rather than reflecting the generation or scaling of corrective actions, they index the early detection and evaluation of unexpected sensory events, consistent with prediction error or surprise processing. Key points When standing balance is disturbed by a perturbation, the brain shows characteristic electrical responses called the balance N1 and theta activity, which are thought to contribute to balance-correcting actions. We tested whether these cortical responses depend on actively controlling posture or instead reflect the detection of unexpected motion irrespective of balance conditions. Participants stood in a robotic balance simulator and experienced identical perturbations while actively balancing or being passively moved, and when whole-body sensory feedback and muscle engagement were removed. The balance N1 and theta activity persisted in conditions where participants were not controlling their movement and even when whole-body sensory feedback and motor engagement were removed, whereas balance-correcting muscle responses were strongly diminished. This shows that cortical responses to balance perturbations are not specific to active balance control but likely represent the brain’s detection and evaluation of unexpected sensory events.","url":"https://doi.org/10.64898/2026.01.08.698388","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.64898/2026.01.08.698388","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1016/j.pacs.2025.100710","name":"Compact

Heavy-Legged Robot (HLR). Servo faults stemming from mechanical wear, environmental disturbances, or electrical issues pose significant challenges to traditional diagnostic methods, which rely heavily on delicate sensors. This study introduces a framework that solely relies on joint position and permanent magnet synchronous motor (PMSM) information to mitigate dependency on fragile sensors for servo-fault diagnosis. An essential contribution involves refining a model that directly connects PMSM currents to HLR motion. Moreover, to address scenarios where actual servo outputs and HLR cylinder velocities are unavailable, an improved sliding mode observer (ISMO) is proposed. Additionally, a Fourier expansion model characterizes the relationship between operation time and fault-free disturbance in the HLR. Subsequently, the dual-line particle filter (DPF) algorithm is employed to predict fault-free disturbance. The outputs of DPF serve as a feedforward to the ISMO, enabling the real-time servo torque fault diagnosis. The accuracy and validity of this technical framework are verified through various simulations in MATLAB/SIMSCAPE and real-world experiments.","url":"https://doi.org/10.1016/j.isatra.2024.02.004","authors":["Liu S","Zhou S","Li B","Niu Z","Abdullah M","Wang

According to risk management tools, the system takes Mitsubishi PLC as the control core and combines with communication module, servo motor drive system and touch screen man-machine interface to realize the risk simulation and automatic control of the packaging unit. The simulation results of PID control model show that the parameters such as speed and torque can be stabilized in a relatively short period of time when the load is suddenly changed within 1.5&#xa0;s. Theoretical verification of the system has small steady-state error, rapid response, and good control effect. The man-machine interface design was carried out and the actual corresponding test experiment was carried out. The experimental results showed that the overall operation rate of the packaging unit system reached 98.15%, the pass rate was 99.03%, and the production capacity was about 9600 packs/hour, which met the production requirements. The control system of the building material packaging unit designed in this paper realizes the equipment intelligence, has a high degree of automation, and shows good potential application value in the aspects of building information, reduction of construction risks and manufacturing intelligence.","url":"https://doi.org/10.1038/s41598-023-51102-3","authors":["Fang J","Deng B"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1038/s41598-023-51102-3","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"doi:10.1371/journal.pone.0304657","name":"Designing and development of agricultural rovers for vegetable harvesting and soil analysis.","source":"europepmc","abstract":"To address the growing demand for sustainable agriculture practices, new technologies to boost crop productivity and soil health must be developed.

We present CAN-DAQ, a complete hardware-software platform that bridges this gap, matching the core features of commercial systems at a fraction of the cost.

CAN-DAQ supports all classic CAN baud rates from 25 kbps to 1 Mbps and achieves a maximum sampling frequency of 1 kHz, reliably capturing 1000 CAN frames per second. As a fully open-source solution, it provides a foundation for users to build custom real-time data analytics applications. The system's effectiveness was validated through comprehensive testing of its data reception, transmission, and sampling capabilities, demonstrating reliable operation against commercial-grade automotive CAN interfaces.","url":"https://doi.org/10.1016/j.ohx.2026.e00743","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1016/j.ohx.2026.e00743","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:44.263Z"},{"id":"doi:10.3390/mi16030245","name":"Guidance Gyro System with Two Gimbals and Magnetic Suspension Gyros Using Adaptive-Type Control Laws.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi16030245","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/mi16030245","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.3390/ani15213177","name":"LIVEMOS-G: A High Throughput Gantry Monitoring System with Multi-Source Imaging and Environmental Sensing for Large-Scale Commercial Rabbit Farming.","source":"europepmc","abstract":"The rising global demand for high-quality animal protein has driven the development of advanced technologies in high-density livestock farming. Rabbits, with their rapid growth, high reproductive efficiency, and excellent feed conversion, play an important role in modern animal agriculture. However, large-scale rabbit farming poses challenges in timely health inspection and environmental monitoring. Traditional manual inspections are labor-intensive, prone-to-error, and inefficient for real-time management. To address these issues, we propose Livestock Environmental Monitoring System-Gantry (LIVEMOS-G), an intelligent gantry-based monitoring system tailored for large-scale rabbit farms. Inspired by plant phenotyping platforms, the system integrates a three-axis motion module with multi-source imaging (RGB, depth, near-infrared, thermal infrared) and an environmental sensing module. It autonomously inspects around the farm, capturing multi-angle, high-resolution images and real-time environmental data without disturbing the rabbits. Key environmental parameters are collected accurately and compared with welfare standards. After training on an original dataset, which contains a total of 2325 sets of images (each set includes RGB, NIR, TIR, and depth image), the system is able to detect dead rabbits using a fusion-based object detection model during inspections. LIVEMOS-G offers a scalable, non-intrusive solution for intelligent livestock inspection, contributing to enhanced biosecurity, animal welfare, and data-driven management in high-density, modern rabbit farms. It also shows the potential to be extended to other species, contributing to the sustainable development of the animal farming industry as a whole.","url":"https://doi.org/10.3390/ani15213177","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/ani15213177","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:36.400Z"},{"id":"doi:10.20944/preprints202407.0353.v1","name":"Real-Time Home Automation System using BCI Technology","source":"europepmc","abstract":"Brain-Computer Interface (BCI) processes and converts brain signals to provide 20 commands to output devices to carry out certain tasks.

detection of hand gestures and discrimination of object size. Tactile contactors representing the first three fingers were driven along the proximodistal axis by linear servo motors. Twenty healthy subjects were involved in the gesture detection test, with 10 of them also participating in the object-size discrimination task. Motors were controlled by computer in the first four sessions of the gesture detection experiment, while the fifth session utilized a sensorized glove. Both the volar and dorsal sides of the forearm were examined. In the object-size discrimination experiment, the method was exclusively assessed on the volar surface under four distinct feedback conditions, including all fingers and each finger separately. The psychophysical data were further analyzed using a structural equation model (SEM) to evaluate the specific contributions of each individual contactor. Subjects consistently outperformed the chance level in detecting gestures. Performance improved up to the third session, with better results obtained on the volar side. The performances were similar in the fourth and fifth sessions. The just noticeable difference for achieving a 75% discrimination accuracy was found to be 2.90&#xa0;mm of movement on the skin. SEM analysis indicated that the contactor for the index finger had the lowest importance in gesture detection, while it played a more significant role in object-size discrimination. However, all fingers were found to be significant predictors of subjects' responses in both experiments, except for the thumb, which was deemed insignificant in object-size discrimination. The study highlights the importance of considering the partial contribution of each degree of freedom in a sensory feedback system, especially concerning the task, when designing such systems.","url":"https://doi.org/10.1007/s10439-023-03434-4","authors":["Devecioğlu İ","Karakulak E"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1007/s10439-023-03434-4","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:51.327Z"},{"id":"doi:10.1038/s41598-024-52600-8","name":"Fuzzy PID control of permanent magnet synchronous motor electric steering engine by improved beetle antennae search algorithm.","source":"pubmed","abstract":"The accuracy of control in permanent magnet synchronous motor system significantly affects overall mechanical structure safety.

The hybrid fuzzy proportional-integral-derivative controller is then implemented in the control model of the permanent magnet synchronous motor, resulting in the establishment of a novel control model for the electric steering engine driven by the permanent magnet synchronous motor. The test results showed that root-mean-square error of this control model was 0.03 mm and 0.02 mm respectively under the conditions of sinusoidal response, square wave response and step response, which was obviously shorter than all the selected control models. In addition, the standard deviation of the control model designed in this study accounted for less than 4% of root-mean-square error of electric steering engine position under the sinusoidal response condition, so the calculation stability was high.

The main function of these motors is to ensure stable positioning performance and speed for mechanical systems based on pre-designed control methods. However, achieving optimal speed performance for servo motors faces many challenges due to the impact of internal and external loads, which affect output stability. To optimize the speed performance of DC Servo motors, a control method combining PID controllers and artificial neural networks has been proposed. Traditional PID controllers have the advantage of a simple structure and effective control capability in many systems, but they face difficulties when dealing with nonlinear and uncertain changes. The neural network is integrated to adjust the PID parameters in real time, helping the system adapt to different operating conditions. Simulation and experimental results have demonstrated that the proposed method significantly improves the speed tracking capability and stability of the motor while ensuring quick response, zero steady-state error, and eliminating overshoot.

Nowadays, this type of motor has only been used in quadratic torque applications and constant torque applications (such as pump and fan industry), as these do not have high requirements in terms of dynamics and accuracy. Despite the potential economic advantage of SynRM, one reason against its usage in servo applications is the nonlinear characteristics of the motor, such as magnetic saturation and torque ripple, which pose a challenge in high-bandwidth and robust control. Within the scope of the dissertation, practical methods for identifying the parameters of mechatronic feed drive systems are proposed. To determine the control-relevant parameters with minimal effort and facilitate timely updates in the presence of parameter uncertainties, different online methods based on the idea of extended Kalman filter (EKF) and recursive least squares (RLS) are introduced. Based on the developed motor model, controller concepts for the current, speed, and position loop are derived with the aim to achieve high bandwidth control performance. Various nonlinear control approaches, including PI gain scheduling, deadbeat control, and model predictive current control, are investigated through both simulation and experimental studies. To ensure industrial applicability, the controllers are implemented and tested with a rapid-prototyping system in combination with a commercial servo drive system. The validation of all presented methods is conducted by designing and evaluating a control system for a feed drive test bench equipped with SynRM. The fulfillment of the machine tool requirements is assessed on the basis of measurements of the step response, setpoint transfer behavior, smallest traversable increment, tracking behavior, and disturbance behavior. Furthermore, an example workpiece is milled on the feed drive test bench to demonstrate the applicability of SynRM in machine tools.","url":"https://doi.org/10.18154/rwth-2024-02336","authors":["Xi, Tiandong"],"tags":["Hochschulschrift","machine tool ; feed drive axis ; synchronous reluctance motor ; control theory"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.18154/rwth-2024-02336","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:35.424Z"},{"id":"doi:10.48550/arxiv.2402.07375","name":"A Unified MPC Strategy for a Tilt-rotor VTOL UAV Towards Seamless Mode Transitioning","source":"datacite","abstract":"Capabilities of long-range flight and vertical take-off and landing (VTOL) are essential for Urban Air Mobility (UAM). Tiltrotor VTOLs have the advantage of balancing control simplicity and system complexity due to their redundant control authority. Prior work on controlling these aircraft either requires separate controllers and switching modes for different vehicle configurations or performs the control allocation on separate actuator sets, which cannot fully use the potential of the redundancy of tiltrotor. This paper introduces a unified MPC-based control strategy for a customized tiltrotor VTOL Unmanned Aerial Vehicle (UAV), which does not require mode-switching and can perform the control allocation in a consistent way. The incorporation of four independently controllable rotors in VTOL design offers an extra level of redundancy, allowing the VTOL to accommodate actuator failures. The result shows that our approach outperforms PID controllers while maintaining unified control. It allows the VTOL to perform smooth acceleration/deceleration, and precise coordinated turns. In addition, the independently controlled tilts enable the vehicle to handle actuator failures, ensuring that the aircraft remains operational even in the event of a servo or motor malfunction.","url":"https://doi.org/10.48550/arxiv.2402.07375","authors":["Chen, Qizhao","Hu, Ziqi","Geng, Junyi","Bai, Dongwei","Mousaei, Mohammad","Scherer, Sebastian"],"tags":["Systems and Control (eess.SY)","Robotics (cs.RO)","FOS: Electrical engineering, electronic engineering, information engineering","FOS: Electrical engineering, electronic engineering, information engineering","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.48550/arxiv.2402.07375","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:35.424Z"},{"id":"doi:10.1101/2024.11.03.621771","name":"Programmable 3D cell alignment of bioprinted tissue via soft robotic dynamic stimulation","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.11.03.621771","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.11.03.621771","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.20944/preprints202401.1246.v1","name":"A Fruit Harvesting Mechanism Capable of Multidimensional Movements: A Preliminary Study on the Integrated Mechanism with a Hexacopter","source":"preprints","abstract":"","url":"https://doi.org/10.20944/preprints202401.1246.v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.20944/preprints202401.1246.v1","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.21203/rs.3.rs-4168960/v1","name":"Robust Obstacle Detection in Hilly Region","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4168960/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4168960/v1","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.1101/2025.04.23.648411","name":"VasoTracker 2: An Open-source Platform for Quantitative Analysis of Vascular Reactivity and Function","source":"preprints","abstract":"VasoTracker 2 is an open-source platform for studying blood vessel dynamics, featuring versatile diameter-tracking software and complementary low-cost hardware components.

While most current strategies exploit physical movement, there is growing interest in harnessing muscle activity directly via surface electromyography (EMG) as a more seamless interface. We systematically compared muscle- (EMG) and movement-based (force sensor) control of a Third Thumb. Using identical instructions and a counterbalanced within-participants design, we assessed initial skill, learning, and cognitive load across a variety of tasks, enabling a blinded comparison across control modalities. Both control modalities afforded successful Third Thumb control and learning, although force control consistently delivered better performance. Despite execution differences, learning rates and cognitive loads were comparable, with a similar evoked sense of agency. Signal analyses showed performance was predicted by real-time force sensor parameters but not by EMG, reflecting distinct control dynamics. Nonetheless, EMG training led to greater skill transfer to force control, suggesting it may better support generalisable learning. These findings challenge the assumption that proximity to neural signals ensures better control. Although EMG underperformed in execution, it showed unique advantages, including enhanced generalisation and access to richer signals, highlighting the need for improved real-time decoding to fully exploit its potential.","url":"https://doi.org/10.1101/2025.06.18.658087","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.06.18.658087","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.21203/rs.3.rs-7418947/v1","name":"Unveiling Earthquakes: Thermoluminescence Signal Resetting of Laboratory-Produced Fault Gouge","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-7418947/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.21203/rs.3.rs-7418947/v1","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.1101/2025.05.14.653752","name":"Mice discriminate odour source distance via sub-sniff temporal features of odour plumes","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2025.05.14.653752","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.05.14.653752","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1101/2025.11.24.690125","name":"Neural encoding of innate preference to gravity-defying motion","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2025.11.24.690125","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.11.24.690125","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.1101/2024.06.02.597005","name":"Facial expressions in mice reveal latent cognitive variables and their neural correlates","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.06.02.597005","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.06.02.597005","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:41.844Z"},{"id":"doi:10.1101/2024.09.06.611641","name":"PIEZO-dependent mechano-sensing of the niche is essential for intestinal stem cell fate decision and maintenance","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.09.06.611641","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.09.06.611641","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:41.844Z"},{"id":"doi:10.1101/2024.01.31.578188","name":"The Switchmaze: an open-design device for measuring motivation and drive switching in mice","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.01.31.578188","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.01.31.578188","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:41.844Z"},{"id":"doi:10.21203/rs.3.rs-4155027/v1","name":"Enhancing Stroke Rehabilitation with Whole-Hand Haptic Rendering: Development and Clinical Usability Evaluation of a Novel Upper-Limb Rehabilitation Device","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4155027/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4155027/v1","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2025.09.16.676524","name":"Movie-trained transformer reveals novel response properties to dynamic stimuli in mouse visual cortex","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2025.09.16.676524","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.09.16.676524","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1101/2024.02.15.580445","name":"Innate face detectors in the nidopallium of young domestic chicks","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.02.15.580445","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.02.15.580445","addedAt":"2026-08-31T06:34:35.424Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.21203/rs.3.rs-4986223/v1","name":"Study on Working Mechanism and Control Method of New Magnetic Suspension Gripper","source":"crossref","abstract":"Abstract The mechanical torsion gripper has widely been used in existing gripper looms which have difficulties in weaving ultra-wide fabrics. The mechanical gripper system generates mechanical impact and friction, limits weft insertion speed, and consumes high energy. This paper introduces a novel high-speed ”frictionless transmission” magnetic method that directly drives gripper continuously through the width of fabric. The basic principle of the magnetic levitation gripper is presented and the dynamics of the gripper model, based on the system magnetic-mechanics analysis is analyzed. For numerical simulation, the revision method is used to solve the original system’s stable state, which includes information about the new magnetic suspension gripper, electronic coil array and controller. A lag-leading revision method is proposed to improve the weft insertion performance and deal with the adverse effects from hysteresis nonlinearity and external disturbance.

The model uncertainty is evaluated under both parametric and global representation. For the latter case, an interesting discussion about the conservativeness of this description is presented by means of a comparison between the uncertainty disk and the critical perturbation radius approaches.

Based on the results of the tests carried out, the results of the validity test were obtained in the very valid category, the results of the practicality test in the very practical category and the results of the effectiveness test in the very effective category.

Finally, the validation of this method is verified by setting up the experimental platform with SPMSM and ZX165U manipulator.","url":"https://doi.org/10.4028/www.scientific.net/amr.694-697.1629","authors":["Lin Yang","Yong Yi He","Shuai Guo","Sheng Bao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-05-14T09:06:58Z","doi":"10.4028/www.scientific.net/amr.694-697.1629","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/icems.2011.6073404","name":"Inertia identification for speed control of PMSM servo motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icems.2011.6073404","authors":["Shuai Du","Shouhua Zhao","Yangsheng Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-11-17T16:15:14Z","doi":"10.1109/icems.2011.6073404","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.2514/6.2011-1641","name":"Chalcogenide-Based Memristive Device Control of a LEGO Mindstorms NXT Servo Motor","source":"crossref","abstract":"","url":"https://doi.org/10.2514/6.2011-1641","authors":["Kolton Drake","Kris Campbell"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-12-18T23:01:04Z","doi":"10.2514/6.2011-1641","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/mace.2011.5988080","name":"Application of preview control in linear motor servo mechanism","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mace.2011.5988080","authors":["Bin Li","Hailong Lu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-08-25T15:56:11Z","doi":"10.1109/mace.2011.5988080","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1109/icacc.2010.5487000","name":"Self-tuning controller for servo motor with an adaptive disturbance observer","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icacc.2010.5487000","authors":["Hongkui Li","Qinglin Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-06-24T14:37:07Z","doi":"10.1109/icacc.2010.5487000","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1117/12.942970","name":"Robust Control Of Brushless Dc Servo Motor Using Dual Passive Adaptive Control Loop","source":"crossref","abstract":"","url":"https://doi.org/10.1117/12.942970","authors":["Kiyoshi Ohishi","Kouhei Ohnishi","Katunori Taniguchi","Masaaki Hotta"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-10-03T00:22:29Z","doi":"10.1117/12.942970","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.550Z"},{"id":"doi:10.1115/1.1804196","name":"Mechanical Optimization of Servo Motor","source":"crossref","abstract":"A servo system moves a mass from one position to another as quickly as possible. A servo motor requires very high short term torque and should be able to accelerate and decelerate very quickly. In other words, a servomotor should be able to produce high torque and its inertia must be low. The paper concentrates on the mechanical design optimization of the rotor assembly, given the existing physical constraints of the prototype motor. The existing physical constraints include the rotor dimensions. To reduce the cogging torque, the different magnet shape and skew were manufactured and tested. Using the above design the ratio of torque to the moment of inertia of the rotor goes to its minimum amount. As a result, the acceleration and deceleration of the system will be improved.","url":"https://doi.org/10.1115/1.1804196","authors":["A. Basu","S. A. Moosavian","R.

However, in spite of the analysis of static behaviors have been done, the dynamic behaviors are not so examined. Our special interest is how to control the nonlinear behaviors of the rolling elements and to operate the feed drive system with high accuracy. In order to model the nonlinear behaviors of the feed drive system, we measure the transient response when the step inputs of microscopic displacement are input to the AC servo motor and the detail analysis will be done. Experimental results show that the step responses become slow as the input displacement becomes microscopic.

Recognizing the existing limitations in parameter optimization and system behavior prediction, a novel hybrid approach is introduced. The methodology combines a Dandelion optimizer algorithm (DOA) for servo motor parameter optimization and an Attention pyramid convolution neural network (APCNN) (APCNN) for system behavior prediction. Integrated with a Programmable Logic Controller (PLC) and human-machine interface (HMI), this approach offers a comprehensive solution. Our research identifies a significant research gap in the efficiency of existing methods, emphasizing the need for improved control parameter optimization and system behavior prediction for cost reduction and enhanced efficiency. Through implementation on the MATLAB platform, the proposed DOA-APCNN approach demonstrates a noteworthy 30% reduction in computation time compared to existing methods such as Heap-based optimizer (HBO), Cuckoo Search Algorithm (CSA), and Salp Swarm Algorithm (SSA).

The model predictive control algorithm considers constraints of a manipulated variable. An ARX model is used in the identification part of the self-tuning controller and its parameters are recursively estimated using the recursive least squares method with the directional forgetting. The control algorithm is based on the Generalised Predictive Control (GPC) method and the optimization was realized by minimization of a quadratic and absolute values objective functions. A recursive control algorithm was designed for computation of individual predictions by incorporating a receding horizon principle.

However, the trade-off between robustness and computational efficiency of existing ball screw thermal error models is complicated and not conducive to practical, high-precision, real-time error compensation. Focusing on this problem, we propose an iterative prediction model of screw thermal error based on a finite difference equation. By assuming an approximately linear relationship between heat generation and the ball screw’s convection power and feed speed, a simplified and more efficient identification of physical parameters needed for the iterative model is achieved. The proposed method is integrated with a three-axis drilling and tapping machine powered by an HNC–848D controller. A test piece machine using the proposed real-time thermal error compensation method exhibited a maximum machining error of 13 µm, compared to the 71 µm of an uncompensated specimen. The proposed method is demonstrated to improve machining accuracy, especially in the X- and Y- axes, and overcome the limitations of traditional thermal error prediction models.","url":"https://doi.org/10.3390/app13052833","authors":["Ren Rong","Huicheng Zhou","Yubin Huang","Jianzhong Yang","Hua Xiang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-02-23T02:01:25Z","doi":"10.3390/app13052833","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.21062/mft.2023.114","name":"Optimization and Experiment of Linear Motor Platform Servo Control Algorithm","source":"crossref","abstract":"","url":"https://doi.org/10.21062/mft.2023.114","authors":["Shu Wang","Xiaoyan Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-19T06:05:31Z","doi":"10.21062/mft.2023.114","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/pccon.2007.373180","name":"Perfect Tracking Control of Servo Motor Based on Precise Model with PWM Hold and Current Loop","source":"crossref","abstract":"","url":"https://doi.org/10.1109/pccon.2007.373180","authors":["Koichi Sakata","Hiroshi Fujimoto"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2007-06-20T11:02:18Z","doi":"10.1109/pccon.2007.373180","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/amc.2000.862937","name":"Self-sensing control of AC-servo motor with DSP oriented observer","source":"crossref","abstract":"","url":"https://doi.org/10.1109/amc.2000.862937","authors":["A.

Motor yang dapat mengendalikan posisi sudut dan menghasilkan kecepatan secara otomatis adalah motor servo. Pengaturan posisi sudut motor servo dapat dilakukan melalui sebuah mikrokontroler yang diprogram dan dihubungkan ke motor servo. Pemrograman ini berfungsi untuk mengatur sudut, posisi, dan kecepatan yang sudah tetap dan tidak bisa diubah secara langsung. Pengubahan program secara tidak langsung menjadi kendala ketika sudut dan posisi motor servo akan diprogram secara berulang. Antarmuka dirancang dan akan digunakan sebagai pengendali motor servo secara langsung agar motor servo tidak diprogram secara berulang. Antarmuka dibuat menggunakan perangkat lunak Octave. Octave mengirim perintah ke motor servo melalui kabel serial yang menghubungkan PC dan mikrokontroller. Setelah itu, Octave akan mengakusisi data dari encoder untuk membandingkan antara masukan dan hasil keluaran pada motor servo. Data perbandingan akan digunakan sebagai feedback dari posisi motor servo jika sudah tepat sesuai masukan. Hasil akhir pada Tugas Akhir ini adalah perangkat lunak berupa antarmuka instrumentasi dan pengendalian motor servo berbasis Octave.Motor applications on a machine generates speed, accuracy, and ease in the field of mechanics and industrial. Motors that can control the angle position and automatically generate speed is servo motor. Setting the angle position of a servo motor can be done via a microcontroller that is programmed and connected to a servo motor. Programming serves to adjust the angle, position, and velocity that have been fixed and can not be modified directly. However, changing the program indirectly becomes a problem when the angle and position of the servo motor will be programmed repeatedly. The interface is designed and to be used as a directly servo motors controller so that the servo motor is not programmed repeatedly. The interface is made using the Octave software. Octave send commands to the servo motor via a serial cable which is connecting the PC and microcontroller. Then, Octave will acquire data from the encoder to compare between the input and output on the servo motor. Comparison data will be used as a feedback of servo motor position whether it is correct according to the inputs. The end result in this thesis is a software in the form of instrumentation interface and servo motor controller which is Octave-based.","url":"https://doi.org/10.61769/telematika.v10i1.126","authors":["Adam Kurnia","Oetomo Oetomo","Herry Sitepu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-20T17:47:54Z","doi":"10.61769/telematika.v10i1.126","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/icet58434.2023.10211614","name":"Design of Switched Reluctance Motor(SRM) Servo Control for Robot Joints","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icet58434.2023.10211614","authors":["Yongsheng Wang","Yuehong Dai","Junyao Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-15T17:25:47Z","doi":"10.1109/icet58434.2023.10211614","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1016/0094-114x(84)90027-2","name":"4364302 Hydraulic control apparatus for a servo-motor, particularly for vehicle steering","source":"crossref","abstract":"","url":"https://doi.org/10.1016/0094-114x(84)90027-2","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2005-02-10T22:04:36Z","doi":"10.1016/0094-114x(84)90027-2","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/i-pact65952.2025.11307893","name":"Position Control of Servo Motor Using Intelligent P Controller","source":"crossref","abstract":"","url":"https://doi.org/10.1109/i-pact65952.2025.11307893","authors":["Kaumudi Sharma","Devakikrishnan H","V.

The permanent magnet synchronous motor-based drives are able to improve the accuracy of the piano tuning process in comparison with the traditional direct-current motor-based and step motor-based servo drives. To explain the techniques, firstly, the structure and principles of the automated piano tuning devices with a surface-mounted permanent magnet synchronous motor-based drive system integrated are introduced, illustrating that it is feasible to implement the proposed piano tuning strategy. Secondly, the piano tuning devices have two functions: low-speed rotation and position holding. To ensure that the surface-mounted permanent magnet synchronous motor can rotate stably over the low-speed range with strong anti-interference capacity, a double closed-loop speed-regulation-based control scheme is employed. And to ensure high position control performance, a fuzzy-adaptive triple closed-loop position-regulation-based control scheme is employed. It terms of the control schemes, it deserves to be mentioned that main contributions include, firstly, the parameters of the proportional integral controllers in the double closed-loop speed-regulation structure is tuned relying on both stability and bandwidth analyses. Then, a fuzzy-adaptive proportional integral controller is specially-designed for the triple closed-loop position-regulation to adapt to the piano tuning applications. Simulation is conducted on a 20 rpm three-phase permanent magnet synchronous motor servo drive-based piano tuning system to validate the proposed piano tuning method and to verify the proposed control techniques.","url":"https://doi.org/10.3390/en14206627","authors":["Ying Zhou","Zuyu Wu","Yutong Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-10-14T09:10:49Z","doi":"10.3390/en14206627","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.3390/act15050269","name":"Asymptotic Motion Control of Motor Servo Systems with Disturbance Compensation and Time-Varying Asymmetric Output Constraints","source":"crossref","abstract":"This paper proposes a novel asymptotic secure tracking controller for motor servo systems.

Additionally, a nonlinear asymptotic filter is incorporated into the design, which effectively circumvents the inherent “explosion of complexity” issue and achieves asymptotic tracking performance. Finally, the stability of the system is demonstrated through Lyapunov-based theoretical analysis, and the effectiveness of the proposed controller is validated by simulation results.","url":"https://doi.org/10.3390/act15050269","authors":["Tianhao Liu","Guichao Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-11T19:35:43Z","doi":"10.3390/act15050269","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/chicc.2016.7554368","name":"Observer-based fault detection for a dual-motor driving servo system","source":"crossref","abstract":"","url":"https://doi.org/10.1109/chicc.2016.7554368","authors":["Fumin Guo","Xuemei Ren","Zhijun Li","Cunwu Han"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-09-21T20:04:17Z","doi":"10.1109/chicc.2016.7554368","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/acc.1994.751808","name":"The application of fuzzy logic control to speed control of a DC servo motor system","source":"crossref","abstract":"","url":"https://doi.org/10.1109/acc.1994.751808","authors":["Ying-Chih Lin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2005-08-24T22:35:58Z","doi":"10.1109/acc.1994.751808","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1016/b978-0-44-315574-1.00008-7","name":"Neural network-based adaptive funnel sliding mode control for servo mechanisms with friction compensation","source":"crossref","abstract":"","url":"https://doi.org/10.1016/b978-0-44-315574-1.00008-7","authors":["Shubo Wang","Jing Na","Xuemei Ren"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-02T09:01:55Z","doi":"10.1016/b978-0-44-315574-1.00008-7","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:35.975Z"},{"id":"doi:10.1016/j.eswa.2024.125137","name":"Deep learning-based fault diagnosis of servo motor bearing using the attention-guided feature aggregation network","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.eswa.2024.125137","authors":["Izaz Raouf","Prashant Kumar","Heung Soo Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-18T18:19:24Z","doi":"10.1016/j.eswa.2024.125137","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:35.975Z"},{"id":"doi:10.1088/2631-8695/ae2767","name":"Integrated control method of multi motor servo drive for CNC based on EMD-GNDO","source":"crossref","abstract":"Abstract The current signals in multi-motor servo drives for CNC systems often exhibit nonlinear disturbances. These disturbances can distort the current loop feedback signal, increase multi-motor collaborative control errors, and degrade the overall integrated control performance. This article proposes a multi motor integrated control method for servo drive of CNC based on EMD-GNDO. Based on the principle of drive integration, a mathematical model of the servo motor is constructed, and its transfer function is calculated. The reference three-phase current values are acquired using an encoder and the M/T method. Through the EMD algorithm, the three-phase winding current signal is adaptively decomposed. Establish the input matrix of the three-phase current signal after EMD decomposition, use a neural network model to establish the multi motor collaborative error control objective function, and establish the constraints of the error control objective function. Based on the GNDO algorithm, the objective function is optimized and solved from both local development and global exploration perspectives. Construct a servo driven multi motor integrated control model, and use the optimal solution obtained from GNDO as the input value in the model. Calculate the difference in three-phase current and obtain the control result of the integrated drive and control through a linear amplifier. Experimental results demonstrate that the proposed method effectively confines current signal fluctuations within ±0.1 A, the maximum error between the optimal parameters does not exceed 0.005, and the overall response time does not exceed 0.3 s. The method achieves accurate integrated control for multi-motor parameter adjustment, characterized by rapid response and excellent dynamic performance.","url":"https://doi.org/10.1088/2631-8695/ae2767","authors":["Hongbo Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-02T23:48:57Z","doi":"10.1088/2631-8695/ae2767","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1016/j.mechatronics.2004.04.001","name":"Model reference discrete-time sliding mode control of linear motor precision servo systems","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.mechatronics.2004.04.001","authors":["Yu-Feng Li","Jan Wikander"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2004-05-01T09:50:20Z","doi":"10.1016/j.mechatronics.2004.04.001","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.23919/acc.2004.1383584","name":"Adaptive position servo control of permanent magnet synchronous motor","source":"crossref","abstract":"","url":"https://doi.org/10.23919/acc.2004.1383584","authors":["Liu Mingji","Cai Zhongqin","Cheng Ximing","Ouyang Minggao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-05-29T00:29:01Z","doi":"10.23919/acc.2004.1383584","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.7753/ijsea1503.1003","name":"Research on Suppression Method of Position Overshoot in Servo Motor Emergency Stop Process under Large Inertia Load","source":"crossref","abstract":"","url":"https://doi.org/10.7753/ijsea1503.1003","authors":["Yaowu Ding"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-02-27T08:38:02Z","doi":"10.7753/ijsea1503.1003","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1016/s0890-6955(00)00061-4","name":"Ultra precision positioning system for servo motor–piezo actuator using the dual servo loop and digital filter implementation","source":"crossref","abstract":"","url":"https://doi.org/10.1016/s0890-6955(00)00061-4","authors":["Heui Jae Pahk","Dong Sung Lee","Jong Ho Park"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2002-07-25T20:57:15Z","doi":"10.1016/s0890-6955(00)00061-4","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1016/b978-0-44-315574-1.00004-x","name":"Contents","source":"crossref","abstract":"","url":"https://doi.org/10.1016/b978-0-44-315574-1.00004-x","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-02T09:01:52Z","doi":"10.1016/b978-0-44-315574-1.00004-x","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:35.975Z"},{"id":"doi:10.1016/0957-4158(92)90029-n","name":"A computer aided design and analysis software for motor sizing in servo control systems","source":"crossref","abstract":"","url":"https://doi.org/10.1016/0957-4158(92)90029-n","authors":["Sabri Cetinkunt","Jean Woloszko"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2003-03-15T04:55:35Z","doi":"10.1016/0957-4158(92)90029-n","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.24843/mettek.2022.v08.i01.p03","name":"Perancangan Peralatan Vakum Penggenggam Pelat Baja pada Trulaser 3030 dengan Motor Servo","source":"crossref","abstract":"Vakum penggenggam adalah suatu alat yang menggunakan vacuum cup sebagai alat penghisap dan penahan beban benda kerja sehingga benda kerja dapat melalui proses pemindahan dari pososi satu ke posisi lainnya.

This research aims to design and implement an automatic dispenser system based on the Arduino Uno with an HC-SR04 sensor and a servo motor as the faucet actuator. This system is designed to improve efficiency and hygiene by eliminating direct contact with the water faucet, thereby reducing the risk of bacterial transmission.

Finally the simulation illustrates the effectiveness of the proposed compensation control strategy.","url":"https://doi.org/10.4028/www.scientific.net/amm.389.448","authors":["Hai Bo Zhao","Yun Guo Zhu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-08-30T11:27:27Z","doi":"10.4028/www.scientific.net/amm.389.448","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/iceice.2011.5777912","name":"Servo motor control system based on free communication port","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iceice.2011.5777912","authors":["Xiao Yanjun","Guan Yuming","Cao Jihong","Liu qi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-05-27T13:28:37Z","doi":"10.1109/iceice.2011.5777912","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/ias.1988.25084","name":"Multimicroprocessor-based robust control of an AC induction servo motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ias.1988.25084","authors":["Ying-Yu Tzou","Hsiang-Jui Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2003-01-06T15:22:18Z","doi":"10.1109/ias.1988.25084","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.22214/ijraset.2019.4566","name":"Speed Control of DC Servo Motor using Different Controllers","source":"crossref","abstract":"","url":"https://doi.org/10.22214/ijraset.2019.4566","authors":["V.

Trauma is the leading cause of amputation in upper limb, accounting for 80% of acquired amputations. The levels of amputation in upper limb are trans-phalangeal, trans-metacarpal, trans-carpal, wrist disarticulation, trans-radial, elbow disarticulation, trans-humeral, shoulder disarticulation, and forequarter amputation. Passive prosthesis is usually prescribed as the involvement of joints is more in amputation and the level of amputation is higher. A passive functional prosthesis can be socially beneficial because it can assist in promoting a psychological acceptance of the amputee’s impaired image. The passive functional prosthesis does provide articulation and need sound limb to achieve desired position. Aim: This study aimed to design and develop modified passive functional shoulder prosthesis incorporating a double-axis hinge shoulder joint with servo motor for enhanced mobility and psychological satisfaction in shoulder disarticulation patient. Method: In this study a patient is taken with the amputation level through the shoulder to which passive functional shoulder prosthesis is prescribed. After this a modified passive functional shoulder prosthesis incorporating a double-axis hinge shoulder joint and servo motor was designed and fabricated for the patients of shoulder disarticulation and pretest data was taken using Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and then prosthesis is given to the patients and after this post test data was taken and data analysis was done. Result: The modified passive functional shoulder prosthesis incorporating a double-axis hinge shoulder joint and servo motor has improved the function and psychological satisfaction of the patient with shoulder disarticulation the pre-test data was 3.7 and the post-test value comes 8.6. Discussion and conclusion: This study showed improved result in the function and psychological satisfaction of the patient with shoulder disarticulation as the passive functional shoulder prosthesis includes the double axis hinge shoulder joint with servo motor is developed which provide two degree of freedom of movement i.e., the flexion and extension motion in sagittal plane using the servo motor which drive the power from the 12V Li-ion battery. In this study, we evaluated the satisfaction of a patient with modified passive function shoulder prosthesis incorporating a double-axis hinge shoulder joint and servo motor and concluded that it provide the function and psychological satisfaction to the patient with shoulder disarticulation.

Flywheel battery is an energy storage device that has been widely studied in recent years. In this paper, a flywheel battery system for servo press energy compensation was put forward. In considering the efficiency and structure robustness, the flux switching permanent magnet (FSPM) motor is appropriate for flywheel battery as energy conversion device. In this study, the flywheel battery structure and working principle were first described. Then the motor characters were analyzed by FEM. After that, a simply initiative power control strategy was introduced for the flywheel battery. Finally, the prototype of flywheel battery with FSPM motor was made and connected to a servo press’s motor driver. The experiments were taken with and without the flywheel battery respectively. The experiment results proved that the flywheel battery could compensate a certain of DC link voltage loss during the press stamping process. That makes the servo press’s driven motor has a more stable power source and reduces the electrical shock to other equipment. In conclusion, the flywheel battery with FSPM motor is an effective energy storage system for servo press. It is believed that with the miniaturization and simplification of flywheel battery, the flywheel battery will be more general in impact load devices.","url":"https://doi.org/10.1115/imece2019-11044","authors":["Chen Liu","Shengdun Zhao","Peng Dong","Peng Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-01-21T17:55:31Z","doi":"10.1115/imece2019-11044","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/icra.2019.8793870","name":"Three-Dimensionally Maneuverable Robotic Fish Enabled by Servo Motor and Water Electrolyser","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra.2019.8793870","authors":["Wenyu Zuo","Alicia Keow","Zheng Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-08-12T21:26:12Z","doi":"10.1109/icra.2019.8793870","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.23919/chicc.2018.8483964","name":"Generalized Extended State Observer Based Speed Control for DC Motor Servo System","source":"crossref","abstract":"","url":"https://doi.org/10.23919/chicc.2018.8483964","authors":["Lan Zhou","Lei Cheng","Changzhong Pan","Zhuang Jiang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-10-09T19:46:51Z","doi":"10.23919/chicc.2018.8483964","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.47617/2072-3172_2020_4_68","name":"Experimental study of the dynamic properties of high-precision dual-motor geared servo drives for technological robots","source":"crossref","abstract":"","url":"https://doi.org/10.47617/2072-3172_2020_4_68","authors":["R.V.

In order to account for nonlinear temperature effects (temperature field distribution, thermal deformation, and electromagnetic material degradation), a multi-physics model of a torque motor builds an equivalent magnetic circuit. The findings indicate that the magnetic degradation of electromagnetic materials at high temperatures is the reason for the decrease in output performance. The magnetomotive force of permanent magnets decreases by 7.9% and the saturation induction of soft magnetic materials decreases by 17.8% at 300°C, which exacerbates local magnetic saturation. As a result, output torque decreases by 8.5%. Static hysteresis width of the motor is 4 mA at 20 °C and decreases by 0.025 mA/°C as the temperature rises; the hysteresis width is dominated by spring tube stiffness (2 mA/(N·m/rad)). This model provides a theoretical basis for predicting performance degradation of torque motors under high temperature operating conditions and supports structural design optimization.","url":"https://doi.org/10.2139/ssrn.6736709","authors":["Yifan Wang","Yaobao Yin","Hong Wang","Xiaoxue Liu","Zhigang Xie","Xiaoping Ouyang","Binbin Deng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-08T23:38:58Z","doi":"10.2139/ssrn.6736709","addedAt":"2026-08-31T06:34:35.975Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1016/0094-114x(83)90068-x","name":"4358724 Solid state servo amplifier for a D.

The system was designed to maintain coop temperature stability automatically, minimizing manual intervention and optimizing environmental conditions for broiler productivity. Using a Research and Development (R&amp;D) approach, the system was constructed with hardware components including NodeMCU ESP8266, DHT11 sensor, servo motor, relay, lamp, and cooling fan, while the software utilized Arduino IDE, Python, and Telegram Bot API for real-time monitoring. The seven-day experimental testing, with thirty readings per day, demonstrated that the system maintained an average temperature of 27.6°C (±0.8°C), achieving 98.5% accuracy compared to manual thermometers, with an average error of 0.65%. The actuators exhibited an average response time of 1.8 seconds, ensuring quick adaptation to environmental changes and preventing heat stress in broilers. The automation reduced manual monitoring time by 80% and inspection frequency by 83%, while lowering energy consumption by approximately 40% through temperature-based device activation. These results confirm that low-cost IoT automation enhances environmental stability, animal welfare, and operational efficiency, aligning with the global trend toward precision livestock farming. Future improvements should focus on integrating multi-node systems, adaptive control algorithms, and humidity regulation to expand scalability, reliability, and sustainability in poultry management.","url":"https://doi.org/10.56347/jics.v4i2.363","authors":["Mukminin Mukminin","Rasiban"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-27T03:02:51Z","doi":"10.56347/jics.v4i2.363","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/icems.2005.202572","name":"Loading field analysis on PMAC servo motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icems.2005.202572","authors":["Jintao Chen","Xiaofeng Gong","Hongmin Jing","Zhigan Wu","Jianping Ying"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-02-06T17:29:16Z","doi":"10.1109/icems.2005.202572","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/aeeca52519.2021.9574233","name":"Design and Research on Miniaturization and Lightness Servo Motor Controller","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aeeca52519.2021.9574233","authors":["Fudao Sun","Jian Luo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-11-02T22:02:30Z","doi":"10.1109/aeeca52519.2021.9574233","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.3901/cjme.2004.supp.209","name":"Research and application of the high frequency response precision linear servo motor system","source":"crossref","abstract":"","url":"https://doi.org/10.3901/cjme.2004.supp.209","authors":["Simin Jiang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-02-12T21:35:05Z","doi":"10.3901/cjme.2004.supp.209","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/iciea.2009.5138298","name":"A new dual-core Permanent Magnet Synchronous Motor Servo System","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iciea.2009.5138298","authors":["Xu Dong","Wang Tianmiao","Wei Hongxing","Liu Jingmeng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-07-01T15:31:34Z","doi":"10.1109/iciea.2009.5138298","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/iceice.2017.8191903","name":"Fully digital control of AC servo motor using fuzzy logic controller","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iceice.2017.8191903","authors":["Neha Khapekar","K.

Simulation results show that the implemented system has satisfactory performance, including good transient responses, good load-disturbance-rejection responses, and good tracking ability.","url":"https://doi.org/10.4028/www.scientific.net/amr.317-319.120","authors":["Li Lin","Hong Wei Tang","Jie Tang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-08-16T11:39:20Z","doi":"10.4028/www.scientific.net/amr.317-319.120","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.1109/iecon.1995.483819","name":"A modified sliding mode speed control scheme for AC servo motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iecon.1995.483819","authors":["Uk-Youl Huh","Je-Hie Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2002-11-19T13:29:13Z","doi":"10.1109/iecon.1995.483819","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.3182/20130902-3-cn-3020.00100","name":"Neural Network-Based Sliding Mode Control for Dual-Motor Servo Systems","source":"crossref","abstract":"","url":"https://doi.org/10.3182/20130902-3-cn-3020.00100","authors":["Wei Zhao","Xuemei Ren"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-01-08T17:05:09Z","doi":"10.3182/20130902-3-cn-3020.00100","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.4236/ica.2011.24051","name":"Blank Holder Force Control System Driven by Servo-Motor","source":"crossref","abstract":"","url":"https://doi.org/10.4236/ica.2011.24051","authors":["Siji Qin","Li Yang","Bing Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-11-29T22:04:56Z","doi":"10.4236/ica.2011.24051","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:43.987Z"},{"id":"doi:10.4028/www.scientific.net/amr.383-390.4878","name":"Torque Ripple Reduction of Brushless DC Servo Motor Using Full EMF Feedback","source":"crossref","abstract":"Torque ripple reduction of the brushless DC motor has been the main issue of the servo drives in which the speed fluctuation and the vibration should be minimized. Un-ideal back EMF (electromagnetic force) usually induces distinct torque ripple. A full EMF feedback strategy is presented in order to effectively reduce torque ripple. The relationship between the terminal voltage of auxiliary winding and the back EMF of brushless DC motor are investigated, and the back EMF can be measured on-line by using the auxiliary winding, the q-axis current for a constant torque to produce is calculated through coordinate transformation when d-axis current is zero, and the reference q-axis current is adjusted in real time by vector control in dq0 coordinate.

be popular in application. This research introduces two novel systems: water hydraulic fluid switching transmission (FST) and pump motor transmission (PMT) that only use cheap ON/OFF valves for lessening the initial cost and reducing the energy consumption; beside, this paper also introduces a conventional servo motor system (SMS) for comparison. Moreover, both FST and PMT systems can recover the kinetic energy of a flywheel in a deceleration process and store it into an accumulator for using in the next working cycle. The experimental results show that the FST system only need from 33.2 to 47.3% of total energy consumption of the SMS to complete a full cycle and even much reducing in PMT system with the reduction from 76.0 to 86.0%. A method to estimate the saved energy stored in the accumulator will be introduced in this study as well and found out that from 8.2 to 11.6% and from 8.7 to 13.7% of the total energy consumption of the FST and PMT systems were recovered. The SMS shows advantage in transient response with the shortest rise time and smallest overshoot while the steady state error is only slightly smaller than the PMT system. The steady state error of FST system is quite large, but it keeps almost same value for all reference velocity; thus, such system is appropriate for applying in high velocity systems. With acceptable velocity response and extremely improving in energy efficiency, the PMT system is promising to replace conventional water hydraulic system in many applications.","url":"https://doi.org/10.1115/fpmc2014-7822","authors":["Pha N.

Metal hammering is one of a traditional handcrafts and only skilled technician can form objective shape from a blank sheet metal without die/mold. It shall be regarded as a type of rapid manufacturing process that is it can be applied to make small amount of sheet metal part. However, to master metal hammering is difficult because of its intricate forming procedure. In this study, a linear servo hammering system, which developed in-house, is adopted as a good mimic of human hammering operation. We have already proposed a calculation method of form difference between workpiece and its CAD data quantitatively in order to assess how workpiece formed accurately and to identify primary factors for the formability. Previous version of our own developed hammering system could form workpiece without considering temporary shape of workpiece with feed-forward control. The operator had to try several times to obtain optimal hammering condition for different shapes of CAD data. It is one of the major differences in comparison with the skilled human operators do. In the study, the authors improved the hammering system to measure shape of workpiece in hammering process. This modification made hammering process to be able to feedback temporary condition to form more accurately. From the experimental result, robustness of the system performance for input shape, compared with that previous system requires several experiments to determine hammering parameter has been demonstrated.","url":"https://doi.org/10.4028/www.scientific.net/kem.625.360","authors":["Hidetake Tanaka","Kaoru Hoshino","Naoki Asakawa"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-08-11T16:05:15Z","doi":"10.4028/www.scientific.net/kem.625.360","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:44.262Z"},{"id":"doi:10.1109/is3c50286.2020.00128","name":"Performance Demands based Servo Motor Speed Control: A Genetic Algorithm Proportional-Integral Control Parameters Design","source":"crossref","abstract":"","url":"https://doi.org/10.1109/is3c50286.2020.00128","authors":["Chao-Chung Peng","Chia-Ling Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-06-21T21:35:13Z","doi":"10.1109/is3c50286.2020.00128","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:44.658Z"},{"id":"doi:10.51622/elpotecs.v3i2.468","name":"Desain Kompensator Motor Servo Dc 734 Pada Laboratorium Dasar Sistem Kendali","source":"crossref","abstract":"Compensation is the arrangement of a system in order to meet the desired specifications.

Though the theoretical adjustment time of the current loop can approach the electrical time constant of PMSM in order of magnitude, constraints such as control frequency make the adjustment time significantly larger than this theoretical limit. Methods This paper introduces a PMSM servo system using a flexible memory controller (FMC) bus for rapid phase current sampling. It leverages an independent current sampling module, equipped with an external analog-to-digital (AD) conversion chip for precise sampling of the output phase current of the PMSM. The sampling precision is 16-bit with a range of 0-3V. The sampled signal is preprocessed by a field-programmable gate array (FPGA), with the phase current data finally transmitted to the primary control chip through the FMC bus. Results By implementing this rapid current sampling architecture, we have successfully reduced the current sampling time by 95.4% while maintaining sampling accuracy. This scheme also substantially shortens the microcontroller unit’s (MCU) interrupt response time, potentially enhancing the current loop's control frequency, ultimately increasing the current loop bandwidth to 20kHz. Conclusions In conclusion, the proposed PMSM servo system with rapid current sampling significantly enhances the performance of the current loop. This advancement in sampling efficiency and control frequency offers substantial improvements for high-precision motion control applications, making it a valuable contribution to the field.","url":"https://doi.org/10.12688/cobot.17690.1","authors":["Yukun Wang","Hongjie Fan","Heyang Feng","Dong Xu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-11T02:25:08Z","doi":"10.12688/cobot.17690.1","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:36.399Z"},{"id":"doi:10.1109/iemdc.2001.939314","name":"Robust integral structure control for AC induction motor servo drives","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iemdc.2001.939314","authors":["Tzuen-Lih Chern","Jia-Shing Wong","Jiluo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2002-11-13T12:02:15Z","doi":"10.1109/iemdc.2001.939314","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:44.658Z"},{"id":"doi:10.1109/ccdc.2017.7978540","name":"Full-order terminal sliding-mode observer for induction motor speed servo systems","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ccdc.2017.7978540","authors":["Zhou Minghao","Feng Yong","Han Fengling","Yu Xinghuo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-07-25T16:10:21Z","doi":"10.1109/ccdc.2017.7978540","addedAt":"2026-08-31T06:34:36.399Z","updatedAt":"2026-08-31T06:34:44.658Z"},{"id":"doi:10.1109/elnano.2015.7146941","name":"Control of hydraulic system servo motor converter in mold oscillation waveform formation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/elnano.2015.7146941","authors":["Viktor O.

While the widely adopted PID controller has proven effective for optimizing control tasks in industries, sliding mode control offers distinct advantages. By controlling the slope of the dynamical trends of state variable behavior, it enables rapid dynamic response with minimal or no overshoot, as well as negligible steady-state error. The robustness of sliding mode control, which makes it highly resilient to changes in plant parameters and outside disturbances, is one of its main advantages. A digital computer simulation was run using Simulink in the MATLAB software, concentrating on a position control system using an armature voltage-controlled D.C. servo motor to assess how well it performed. To learn more about the operation of sliding mode control, several control laws were used and state trajectories were examined. When compared to the conventional tuned PID control, the findings and discussion conclusively show sliding mode control to be more successful. The sliding mode technique has exceptional effectiveness, including enhanced dynamic response, less overshoot, and almost no steady-state error. Furthermore, its robust nature ensures consistent operation even in the face of parameter fluctuations and external disturbances. This study underscores the immense potential of sliding mode control as a powerful alternative to conventional control methods.

An image taken with the camera connected to Gantry robot is transferred to the Matlab environment. The coordinate data obtained by processing the image are separated for the coordinates used, and the position control of the motors is provided. First, the image was changed to grayscale to apply image processing methods. Then, with the image processing formula, ‘viscircles’ has been applied to mark the detected circles. The obtained coordinates were transferred to IndraWorks PLC to be used in the portal robot. Objects in the determined coordinates were moved to another coordinate with the help of the pneumatic system that integrated to Gantry Robot. The system has been tested for different conditions. As a result of studies, it has been observed that both the image processing method and the system work simultaneously with high accuracy.

These configurations can be accompanied by kinematic singularities, backlash, limited power density and efficiency, and computationally expensive inverse kinematics. This paper details the design, fabrication and experimental testing of permanent magnet synchronous spherical motors (PMSSM) for multi-DOF servo-actuation. Its stator-pole arrangement is based on a Goldberg polyhedron, with each pole comprised of hexagonal or pentagonal inner and outer plates. The stator geometry and winding configurations are optimized using electromagnetic finite element analysis. A custom-made controller board includes a microcontroller, servo drivers, a wireless serial interface, and a USB PC interface. Angular orientation is sensed using an inertial measurement unit in wireless communication with the microcontroller. A PID controller is implemented and demonstrated for time-varying reference trajectories.","url":"https://doi.org/10.3390/machines10080612","authors":["Jay A. Shah","Samuel R. Miller","Shaphan R.

Three optimization approaches, namely the Genetic Algorithm (GA), Grey Wolf Optimization (GWO), and a Hybrid Genetic Algorithm Grey Wolf Optimization (HGAGWO), are employed to determine the optimal PID controller parameters for high-precision speed and position control under varying operating conditions and load disturbances. The proposed framework combines advanced optimization techniques with experimental validation to provide a reliable assessment of controller performance in practical industrial environments. The experimental platform consists of a programmable logic controller (PLC), a human-machine interface (HMI), an AC servo drive, and a high-resolution external encoder, while MATLAB/Simulink is utilized to develop and validate the dynamic model. Controller performance is systematically evaluated using widely accepted dynamic performance indices, including rising time, settling time, overshoot, steady-state error, and tracking capability under different operating scenarios. The controller optimization study addresses backlash, one of the most significant nonlinearities affecting servo drive accuracy. A backlash compensation strategy is implemented and experimentally verified, demonstrating a noticeable improvement in positioning precision and motion stability. Comparative simulation and experimental results confirm that the optimized PID controllers significantly enhance the transient response, disturbance-rejection capability, tracking accuracy, and overall system robustness compared with conventional PID tuning methods. Among the investigated optimization techniques, the proposed HGAGWO algorithm effectively combines the global exploration capability of GA with the fast convergence characteristics of GWO, producing superior optimization accuracy, faster convergence, and more reliable controller tuning. The close agreement between simulation and experimental results further validates the effectiveness and practical applicability of the proposed methodology. Therefore, the integration of intelligent PID optimization with backlash compensation provides a robust and efficient motion control solution for high-performance industrial servo systems operating under nonlinearities, load variations, and parameter uncertainties.","url":"https://doi.org/10.1038/s41598-026-64125-3","authors":["Shereen A.

By mimicking the pore-canal-alveolus architecture and noncontact sensing functionality of the Ampullae of Lorenzini (AL), this work develops an AL-inspired capacitive e-skin (ALC e-skin) capable of multimodal sensing, material recognition, interactive control, and stretchable electromagnetic interference (EMI) shielding within a single soft platform. The ALC e-skin is fabricated through a scalable blade-spin coating strategy that forms continuous liquid metal (LM) films on the beaded electrospun fibers. It also achieves a proximity detection range of 250 mm, a broad pressure sensing range up to 260 kPa, and excellent linearity in stretch sensing. The ALC e-skin is further used to demonstrate a robotic recognition and gripping system that accurately recognizes, grips, and sorts four objects with different materials, as well as a multimodal control board that converts proximity, touch, and pressure signals into reliable servo motor commands. Importantly, ALC e-skin provides stretchable EMI shielding, acting as a flexible Faraday cage for robotic systems.

Rapid acquisition of high-quality QXAFS data was realized by combining a servo-motor-driven Si channel-cut monochromator with a tapered undulator. Two tandemly aligned monochromators with channel-cut Si(111) and Si(220) crystals covered energy ranges of 4.0-28.2 keV and 6.6-46.0 keV, respectively. The system allows the users to adjust instantly the energy ranges of scans, the starting angles of oscillations, and the frequencies. The channel-cut crystals are cooled with liquid nitrogen to enable them to withstand the high heat load from the undulator radiation. Deformation of the reflecting planes is reduced by clamping each crystal with two cooling blocks. Performance tests at the Cu K-edge demonstrated sufficiently high data quality for x-ray absorption near-edge structure and extended x-ray absorption fine-structure analyses with temporal resolutions of up to 10 and 25 ms, respectively.","url":"https://doi.org/10.1063/1.4746770","authors":["Nonaka T","Dohmae K","Araki T","Hayashi Y","Hirose Y","Uruga T","Yamazaki H","Mochizuki T","Tanida H","Goto S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2012","doi":"10.1063/1.4746770","addedAt":"2026-08-31T06:34:37.818Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.3390/s26092862","name":"An Ultralight Launch-and-Recovery System for Tethered Micro Unmanned Aerial Vehicles on Small Unmanned Ground Vehicles.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26092862","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26092862","addedAt":"2026-08-31T06:34:37.818Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1002/advs.202523518","name":"Bioinspired Adaptive Leg-Claw Enables Robust Perching and Grasping for UAVs.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/advs.202523518","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202523518","addedAt":"2026-08-31T06:34:37.818Z","updatedAt":"2026-08-31T06:34:44.263Z"},{"id":"doi:10.3390/s25247555","name":"Laser Pulse-Driven Multi-Sensor Time Synchronization Method for LiDAR Systems.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25247555","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25247555","addedAt":"2026-08-31T06:34:37.818Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.3390/s25041154","name":"Industrial Robot Control System with a Predictive Maintenance Module Using IIoT Technology.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25041154","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25041154","addedAt":"2026-08-31T06:34:37.818Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.3390/s26031050","name":"Research on the Control Algorithm for a Brushless DC Motor Based on an Adaptive Extended Kalman Filter.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26031050","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26031050","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.3390/s26082446","name":"An Optical Method for the Rapid Measurement of Corrugated Plate Depth Based on Line Laser Sensor.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26082446","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26082446","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1038/s41598-026-48914-4","name":"Modeling and experimental confirmation of a new start method utilizing mechanical resonance for the linear range extender.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-026-48914-4","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41598-026-48914-4","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1371/journal.pone.0351628","name":"A deep learning-based automated Solar-Powered Fish Monitoring System.","source":"europepmc","abstract":"Green fish farming represents an integrated aquaculture approach that rears aquatic organisms in controlled environments to improve production efficiency and environmental sustainability. Although significant, current green fish farming practices are labour-intensive and expensive due to grid energy dependency resulting in operational inefficiencies and elevated fish mortality. To address these key challenges, we propose a multidisciplinary approach that involves the development of a cost-effective, solar-powered automation system that integrates computer vision and deep learning techniques for real-time monitoring of fish behaviour, water quality, feeding, and waste management. First, we design the system architecture that enables automation and ensures accurate system performance under varying conditions. Second, following the architecture, we build a complete and cost-effective smart system that works along with an intelligent software framework that leverages computer vision and deep learning techniques. Utilizing custom datasets from video frames and environmental sensors, this system utilizes convolutional neural networks (CNNs) for fish behavior analysis, real-time disease detection via camera feeds, and precise feeding control through actuators. The design also incorporates a renewable energy subsystem, employing advanced photovoltaic panels and efficient battery storage to guarantee reliable power. The major contribution lies in the seamless integration of these multidisciplinary components.

A single monocular sensor's sole visual data serves as the basis for our method. The fundamental idea is to manage and control the dynamics associated with any trajectory generated in the image plane. We show that the differential flatness of the system's dynamics can be used to limit arbitrary paths based on the number of points on the object that need to be reached in the image plane. This creates a link between the current configuration and the desired configuration. The number of required points depends on the number of control inputs of the robot used and determines the dimension of the flat output of the system. For a two-wheeled mobile robot, for instance, the coordinates of a single point on the object in the image plane are sufficient, whereas, for a quadcopter with four rotating motors, the trajectory needs to be defined by the coordinates of two points in the image plane. By guaranteeing precise tracking of the chosen trajectory in the image plane, we ensure that problems of collision with obstacles and leaving the camera's field of view are avoided. Our approach is based on the principle of the inverse problem, meaning that when any point on the object is selected in the image plane, it will not be occluded by obstacles or leave the camera's field of view during movement. It is true that proposing any trajectory in the image plane can lead to non-intuitive movements (back and forth) in the Cartesian plane. In the case of backward motion, the robot may collide with obstacles as it navigates without direct vision. Therefore, it is essential to perform optimal trajectory planning that avoids backward movements. To assess the effectiveness of our method, our study focuses exclusively on the challenge of implementing the generated trajectory in the image plane within the specific context of a two-wheeled mobile robot. We use numerical simulations to illustrate the performance of the control strategy we have developed.","url":"https://pubmed.ncbi.nlm.nih.gov/38139512/","authors":["Albekairi M","Mekki H","Kaaniche K","Yousef A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2023 Dec 7","doi":"10.3390/s23249667","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:38082645","name":"Precision Control of Fingertip Force by a Biorealistic Hand with a Pair of Neuromorphic Muscles().","source":"pubmed","abstract":"In this paper, the ability of precision control of fingertip forces was investigated in an antagonistic cable-driven prosthetic hand with neuromorphic twin of muscles.

However, in the field of terrestrial bio-inspired legged robotics, the tail is often ignored because of the difficulties in design and control. In this study, we test the hypothesis that a variable stiffness robotic tail can improve the performance of a sprawling quadruped robot by enhancing its stability and maneuverability in various environments. In order to validate our hypothesis, we integrated a cable-driven, flexible tail with multiple segments into the underactuated sprawling quadruped robot, where a single servo motor working alongside a reel and cable mechanism regulates the tail's stiffness.

The interplay between neural and mechanical systems occurs at all levels of biological organization concurrently, from the tuning of leg muscle properties while running to the dynamics of the limbs interacting with the ground. Understanding the conditions under which animals shift their neural control strategies toward intrinsic muscle mechanics ('preflexes') in the control hierarchy would allow muscle models to predict in vivo muscle force and work more accurately. To understand in vivo muscle mechanics, ex vivo investigation of muscle force and work under dynamically varying strain and loading conditions similar to in vivo locomotion is required. In vivo strain trajectories typically exhibit abrupt changes (i.e., strain and velocity transients) that arise from interactions among neural activation, musculoskeletal kinematics, and loads applied by the environment. The principal goal of our \"avatar\" technique is to investigate how muscles function during abrupt changes in strain rate and loading when the contribution of intrinsic mechanical properties to muscle force production may be highest. In the \"avatar\" technique, the traditional work-loop approach is modified using measured in vivo strain trajectories and electromyographic (EMG) signals from animals during dynamic movements to drive ex vivo muscles through multiple stretch-shortening cycles. This approach is similar to the work-loop technique, except that in vivo strain trajectories are scaled appropriately and imposed on ex vivo mouse muscles attached to a servo motor. This technique allows one to: (1) emulate in vivo strain, activation, stride frequency, and work-loop patterns; (2) vary these patterns to match in vivo force responses most accurately; and (3) vary specific features of strain and/or activation in controlled combinations to test mechanistic hypotheses.","url":"https://pubmed.ncbi.nlm.nih.gov/37607076/","authors":["Bemis C","Nishikawa K"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2023 Aug 18","doi":"10.3791/65610","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:37576648","name":"Digital Control Method and Performance Analysis of the Double-Compound Axial Piston Pump.","source":"pubmed","abstract":"The flow control range of the double-compound axial piston pump with the traditional mechanical-hydraulic feedback servo control is limited and the accuracy is poor.

Additionally, a telephoto camera and quadrant photodetectors were installed to monitor beam positions, and beam position control was implemented to optimize the mirror response.

This paper discusses the hydraulic-based principle of the impact test system, adopts the hydraulic control mode, and uses the accumulator as the power source to develop an instant loading test system suitable for the entire series of steel joints and small-scale cable impact tests.

Specifically, the implementation strategy of functional electrical stimulation walking aid combined with the design of the exoskeleton part is the main focus of our research team. This work copes with issues of the design process of a robotic exoskeleton.

Despite many proposals, the current devices and systems lack maturity and do not completely fulfill user requirements and satisfaction. Increased research activity in this field is required in order to encourage the development, commercialization, and widespread acceptance of low-cost and affordable assistive technologies for visual impairment and other disabilities. This paper proposes a novel approach using a LiDAR with a servo motor and an ultrasonic sensor to collect data and predict objects using deep learning for environment perception and navigation. We adopted this approach using a pair of smart glasses, called LidSonic V2.0, to enable the identification of obstacles for the visually impaired. The LidSonic system consists of an Arduino Uno edge computing device integrated into the smart glasses and a smartphone app that transmits data via Bluetooth. Arduino gathers data, operates the sensors on the smart glasses, detects obstacles using simple data processing, and provides buzzer feedback to visually impaired users. The smartphone application collects data from Arduino, detects and classifies items in the spatial environment, and gives spoken feedback to the user on the detected objects. In comparison to image-processing-based glasses, LidSonic uses far less processing time and energy to classify obstacles using simple LiDAR data, according to several integer measurements. We comprehensively describe the proposed system's hardware and software design, having constructed their prototype implementations and tested them in real-world environments. Using the open platforms, WEKA and TensorFlow, the entire LidSonic system is built with affordable off-the-shelf sensors and a microcontroller board costing less than USD 80. Essentially, we provide designs of an inexpensive, miniature green device that can be built into, or mounted on, any pair of glasses or even a wheelchair to help the visually impaired.

In some conditions, such as heart failure, central apneic events are due to transient inhibition of ventilatory motor output during sleep, owing to the overlapping influences of sleep and hypocapnia. Specifically, the sleep state is associated with removal of wakefulness drive to breathe; thus, rendering ventilatory motor output dependent on the metabolic ventilatory control system, principally PaCO2. Accordingly, central apnea occurs when PaCO2 is reduced below the \"apneic threshold\". Our understanding of the pathophysiology of central sleep apnea has evolved appreciably over the past decade; accordingly, in disorders such as heart failure, central apnea is viewed as a form of breathing instability, manifesting as recurrent cycles of apnea/hypopnea, alternating with hyperpnea. In other words, ventilatory control operates as a negative-feedback closed-loop system to maintain homeostasis of blood gas tensions within a relatively narrow physiologic range, principally PaCO2. Therefore, many authors have adopted the engineering concept of \"loop gain\" (LG) as a measure of ventilatory instability and susceptibility to central apnea. Increased LG promotes breathing instabilities in a number of medical disorders. In some other conditions, such as with use of opioids, central apnea occurs due to inhibition of rhythm generation within the brainstem. This review will address the pathogenesis, pathophysiologic classification, and the multitude of clinical conditions that are associated with central apnea, and highlight areas of uncertainty.","url":"https://pubmed.ncbi.nlm.nih.gov/35551411/","authors":["Javaheri S","Badr MS"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2023 Mar 9","doi":"10.1093/sleep/zsac113","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:35457891","name":"Fuzzy Logic and Genetic-Based Algorithm for a Servo Control System.","source":"pubmed","abstract":"Performing control is necessary for processes where a variable needs to be regulated.

It is not, however, clear how neck reflexes to stretch can be voluntarily suppressed. Reflexive responses might be modified by adjusting the gain of the reflex loop through descending control. Theoretically, necessary corrections upon interfering disturbances during coordinated motor performance requiring the interplay of relaxation/activation may be missing if muscle relaxation is taking place exclusively by this mechanism. It has been alternatively proposed that sensory information from the periphery may be allowed to \"neutralize\" neck reflexes if it is fed back with opposite sign to the structures driving the reflexes. Six healthy subjects were asked to relax while subjected to head-on-trunk rotations generated by a head motor. After any initial resistance had completely subsided, the head was unexpectedly exposed to \"ramp-and-hold\" perturbations of up to 2&#xb0; amplitude and 0.7 s duration. Resistance to stretch consistently reappeared thereupon, suggesting that stretch reflex gain had not been set to zero during the previously achieved complete relaxation. Resistance to perturbations under these circumstances was compared with the forces generated when the same ramp-and-hold displacements were delivered unpredictably to the head held stationary. A quantitative model of neck proprioceptive reflexes suppression has been thus constructed. Gain scheduling or \"motor set\" cannot sufficiently account for the voluntary reflex suppression during slow passive head rotations. Instead, we propose as underlying mechanism, the \"neutralization\" of the controlling servo by means of continuous feedback tracking displacement and force signals from the periphery. NEW &amp; NOTEWORTHY Head stabilizing neck reflexes can be voluntarily suppressed or activated depending on the task at hand. By applying brief perturbations unexpectedly, both during passive head-on-trunk movements and at rest, we investigated the mechanism of voluntary suppression of resistance to stretch. A physiologically plausible, neuromechanical model of voluntary/reflexive interactions was constructed favoring feedback over reflex gain adjustments. Accordingly, muscle relaxation during imposed head movements is based on sensory feedback similarly to muscle contractions during purposeful movements.","url":"https://pubmed.ncbi.nlm.nih.gov/34907798/","authors":["Anastasopoulos D","Anastasopoulos L","Mergner T"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2022 Jan 1","doi":"10.1152/jn.00297.2021","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:34899980","name":"Quantitative Investigation of Hand Grasp Functionality: Hand Joint Motion Correlation, Independence, and Grasping Behavior.","source":"pubmed","abstract":"Modeling and understanding human grasp functionality are fundamental in prosthetics, robotics, medicine, and rehabilitation, since they contribute to exploring motor control mechanism, evaluating grasp function, and designing and controlling prosthetic hands or exoskeletons.

The main contribution of this paper is the proposition of a new decoupling control algorithm that in which, the driving (commanding) voltages of the connected driving motors are extracted separately and independently using the Lyapunov principle in discrete time. In fact, the obtained coupled stabilizing convex inequalities of the controlling voltages, resulting from the evaluation of the Lyapunov functions, are analytically decoupled using elementary matrix operations. Consequently, each motor now has the capability to perform its controlling task (position control or torque control) with asymptotic stability and robustness against uncertainty. To assess the performance of the proposed controlling algorithm and its verification, a MFMADC machine is attached to a harmonic drive reducer (HDR) whose flex spline and circular spline are fabricated using viscoelastic polyesters PLA and thermoplastic PLA, respectively. A number of experiments are conducted where in the first test, the MFMADC is controlled in only-position mode while in the second test, the MFMADC is controlled in simultaneous position-torque control mode.

This technique is based on the use of an electromechanical finger-lifting device that enables a joint motor action initiated by a participant and completed by the machine. The joint action, later referred to as an \"active-passive\" action, was implemented as a reaction time task and contrasted with other levels of participant's involvement, including active movement, passive movement, and observation of a dummy's movement. In each trial, a feedback sound signal informed the participant whether they had performed the task successfully, i.e. faster than a threshold, which was individually adjusted in the beginning of the experiment. In the active condition, the result depended on the participant, while in other conditions it was preprogrammed for the servo. In context of this task, we studied direct time estimates made by participants and auditory event-related potentials (ERP) in 20 healthy volunteers. The amplitude of the auditory N1 component in the responses to the feedback sound showed no significant effect of activity and success factors, while its latency was shorter in successful trials. Interaction of activity and success factors was significant for subjective time estimates. Surprisingly, the intentional binding effect (subjective compression of time intervals, which is known as a correlate of SoA) only emerged in trials of active condition with negative results. This observation was in contrast with the fact that the active and active-passive movements were both voluntarily initiated by the participant. We believe that studying SoA with the proposed technique may not only add to the understanding of agency but also provide practically relevant results for the development of human-machine systems such as exoskeletons.","url":"https://pubmed.ncbi.nlm.nih.gov/33880602/","authors":["Dubynin IA","Yashin AS","Velichkovsky BM","Shishkin SL"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2021 Jun","doi":"10.1007/s00221-021-06105-9","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:33808860","name":"Design of a Sensitive Balloon Sensor for Safe Human-Robot Interaction.","source":"pubmed","abstract":"As the safety of a human body is the main priority while interacting with robots, the field of tactile sensors has expanded for acquiring tactile information and ensuring safe human-robot interaction (HRI).

Thus, the platform can be more easily operated via an ordinary user without expertise in photonics. It is designed based on conventional optical communication wavelength range. The C-band superluminescent-light-emitting-diode light source couples in/out the microring sensor to obtain quasi-TE mode by grating coupler techniques.

However, it generally requires expensive equipment such as RNA isolation instruments and real-time PCR thermal cyclers. As a pandemic, COVID-19 has spread indiscriminately, and many low resource settings and developing countries do not have the means for fast and accurate COVID-19 detection to control the outbreak. Additionally, long assay times, in part caused by slow sample preparation steps, have created a large backlog when testing patient samples suspected of COVID-19. With many PCR-based molecular assays including an extraction step, this can take a significant amount of time and labor, especially if the extraction is performed manually. Using COVID-19 clinical specimens, we have collected evidence that the RT-qPCR assay can feasibly be performed directly on patient sample material in virus transport medium (VTM) without an RNA extraction step, while still producing sensitive test results. If RNA extraction steps can be omitted without significantly affecting clinical sensitivity, the turn-around time of COVID-19 tests, and the backlog we currently experience can be reduced drastically. Furthermore, our data suggest that rapid RT-PCR can be implemented for sensitive and specific molecular diagnosis of COVID-19 in locations where sophisticated laboratory instruments are not available. Our USD 300 set up achieved rapid RT-PCR using thin-walled PCR tubes and a water bath setup using sous vide immersion heaters, a Raspberry Pi computer, and a single servo motor that can process up to 96 samples at a time. Using COVID-19 positive clinical specimens, we demonstrated that RT-PCR assays can be performed in as little as 12 min using untreated samples, heat-inactivated samples, or extracted RNA templates with our low-cost water bath setup.

Finally, the surface morphology and piezoelectric properties of the as-electrospun PVDF fibers were examined by scanning electron microscopy (SEM) and characterized by electrical response measurement techniques.

The technology in question is termed Independent Metering (IM); this is used in hydraulically driven mobile machinery, such as agricultural, construction, municipal, and forestry vehicles. The idea behind the concept is to modify the connection between the actuator, which could be a cylinder or a motor, and a flow control valve. Traditionally, spool hydraulic valves were used to control the fluid flow into and out of hydraulic actuators. This keeps the meter-in and the meter-out of the actuator mechanically connected due to the construction of these valves. This connection makes the control system blind to pressure changes in one of the hydraulic chambers in the actuator. This, in turn, reduces the overall system controllability. It also increases energy losses, especially under an overrunning load. These two main weaknesses led researchers to break this mechanical connection and get into a new technology with different characteristics. The proposed technology was called Independent Metering. New and more complex control techniques can now be applied to the hydraulic systems using this technology that were not possible before or could be applied to more conventional servo design. This paper reviews Independent Metering (IM) and the technologies used or developed in this field to date. The paper reviews the state of art hydraulic technologies and indicates the links between them and IM. It also reviews the different types of hydraulic valves used when implementing IM.

Thus, the performance indexes associated with each input can be optimized as an outcome of a Nash equilibrium.

Numerous conservative treatment strategies have been developed to delay time to total joint replacement. Unloader braces are commonly prescribed for medial uni-compartmental KOA, however their evidence of efficacy is inconclusive and limited by user compliance. Typical commercial braces transfer load from the medial knee compartment to the lateral knee compartment by applying a continuous brace abduction moment (BAM). We propose that brace utilization and effectiveness could be improved with a robotic device that intelligently modulates BAM in real time over the course of a step, day, and year to better protect the knee joint, improve pain relief, and increase comfort. To this end, we developed a robotic unloader knee brace ABLE (active brace for laboratory exploration) to flexibly emulate and explore different active and passive brace behaviors that may be more efficacious than traditional braces. The system is capable of modulating BAM within each step per researcher defined unloading profiles. ABLE was realized as a lightweight orthosis driven by an off-board system containing a servo motor, drive, real-time controller, and host PC. Frequency response and intra-step trajectory tracking during level-ground walking were evaluated in a single healthy human subject test to verify system performance. The system tracked BAM vs percent gait cycle trajectories with a root mean square error of 0.18 to 0.58 Nm for conditions varying in walking speed, 85-115% nominal, and trajectory peak BAM, 2.7 to 8.1 Nm.

While off-board robotic actuation systems provide many benefits, the impedance at the robotic joint is often high. High joint impedance is undesirable for wearable devices like exoskeletons, as the user is unable to move their joint without actively controlled motion from the motors. We propose that the impedance can be reduced substantially in off-board robotic actuation systems by minimizing the reflected inertia from the motor. We have developed a model and optimization-based methodology for selecting a motor and set of mechanical design parameters that minimize reflected inertia. This methodology was implemented in the design of an off-board knee exoskeleton as a case study. A grey-box model was developed that incorporates biomechanical knee trajectories, an experimentally determined human-device interface stiffness model, Bowden cable stiffness and friction, and a motor model. A constrained optimization routine was developed that uses the model and a library of157 candidate servo motors to select the actuator and mechanical design parameters that minimize reflected inertia at the exoskeleton joint. We found that S6 of the motors were able to carry out the necessary torque-velocity trajectories to achieve the prescribed exoskeleton joint torques and limb motions. The optimal motor was the Kollmorgen C133A-one of the largest in the library of candidate servo motors and required a 2.25 cm actuator pulley at the knee joint and a 17.5 cm cable sheave at the motor output.

This research proposes a new indoor method for casting dynamic/automatic visual cues for PwP based on their head direction and location in a room.

Tube motion is governed by multiple interactions between the main flow and the jets exiting the tubes, resulting in chaotic velocity fluctuations and high turbulence intensities in the test section. After describing the structure of the turbulence generator, the turbulent properties of the airflow downstream of the grid in both passive and active modes are measured by hot-wire anemometry and compared with one another. When activating the turbulence generator, turbulence intensity, turbulent kinetic energy, and the Taylor Reynolds number are noticeably increased in comparison with the passive mode (corresponding to simple grid turbulence). Furthermore, the inertial subrange of the turbulent energy spectrum becomes wider and closely follows Kolmogorov's -5/3 law. These results show that the semi-active grid, in contrast to passive systems, is capable of producing high turbulence levels, even at low incoming flow velocity.

It must be designed in such a way that it can produce proper augmented control moments modulated by a closed-loop attitude controller for active stabilization. We propose a tailless FW-MAV with a wing stroke plane modulation mechanism, namely NUS-Roboticbird, which maneuvers by only using its flapping wings for both propulsion and attitude control. The flying vehicle has four wings comprised by two pairs, and each pair of wings and its stroke plane are driven by a motor and a servo, respectively. Attitude control moments of roll, pitch and yaw are generated by vectoring a pair of thrusts, which result from changing the flapping frequency (or motor speed) and wing stroke plane of the two pairs of wings. Free-flight tests show that the vehicle can climb and descend vertically (throttle control), fly sideways left and right (roll control), fly forwards and backwards (pitch control), rotate clockwise and counter-clockwise (yaw control), hover in mid-air (active self-stabilization), and maneuver in the figure-of-8 and fast forward/backward flight. These abilities are especially important for surveillance and autonomous flight in terms of obstacle avoidance in an indoor environment. Flight test data show that an effective mechanical control mechanism and control gains for attitude-controlled flights for roll, pitch and yaw are achieved, in particular, yaw control.

When the instance microrobot starts a lateral motion, the drag force acting on it increases. Thus, the microrobot is unable to move parallel to the surface due to the existence of drag force that cannot be neglected, particularly at high speeds such as &gt;5 mm/s. The effect of it scales exponentially at different speeds and the head-tilting angle of the microrobot changes relative to the reference surface. To the best of our knowledge, there is no prior study on this problem, and no solution has been proposed so far. In this study, we developed and experimented with 3 control models to stabilize microrobot motion characteristics in liquid media to achieve accurate lateral locomotion. The microrobot moves in an untethered manner, and its localization is carried out by a neodymium magnet (grade N48) placed inside its polymer body. This permanent magnet is called a carrier-magnet. The fabricated microrobot is levitated diamagnetically using a pyrolytic graphite placed under it and an external permanent magnet, called a lifter-magnet (grade N48), aligned above it. The lifter-magnet is attached to a servo motor mechanism which can control carrier-magnet orientation along with roll and pitch axes. Controlling the angle of this servo motor, together with the lifter-magnet, allowed us to cope with the head-tilting reaction instantly. Based on the finite element method (FEM), analyses that were designed according to this experimental setup, the equations giving the relation of microrobot speed with servo motor angle along with the microrobot head-tilting angle with servo motor angle, were derived. The control inputs were obtained by COMSOL &#xae; (version 5.3, COMSOL Inc., Stockholm, Sweden). Using these derived equations, the rule-based model, laser model, and hybrid model techniques were proposed in this study to decrease the head-tilting angle. Motion control algorithms were applied in di-ionized water medium. According to the results for these 3 control strategies, at higher speeds (&gt;5 mm/s) and 5 mm horizontal motion trajectory, the average head-tilting angle was reduced to 2.7&#xb0; with the ruled-based model, 1.1&#xb0; with the laser model, and 0.7&#xb0; with the hybrid model.","url":"https://pubmed.ncbi.nlm.nih.gov/30424296/","authors":["Demircali AA","Uvet H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2018 Jul 23","doi":"10.3390/mi9070363","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:30424000","name":"Virtual Torque Sensor for Low-Cost RC Servo Motors Based on Dynamic System Identification Utilizing Parametric Constraints.","source":"pubmed","abstract":"We propose a novel virtual torque sensor for commercial low-cost radio-controlled (RC) servo motors.

The control principles of the Kohnstamm have been investigated using mechanical perturbations, but previous studies could not dissociate sensorimotor responses to perturbation from effects of gravity. We induced a horizontal, gravity-independent Kohnstamm movement around the shoulder joint, and applied resistive or assistive torques of 0.5 Nm after 20&#xb0; angular displacement. A No perturbation control condition was included. Further, participants made velocity-matched voluntary movements, with or without similar perturbations, yielding a 2 &#xd7; 3 factorial design. Resistive perturbations produced an increase in agonist electromyography (EMG), in both Kohnstamm and voluntary movements, while assistive perturbations produced a decrease. While overall Kohnstamm EMGs were greater than voluntary EMGs, the EMG responses to perturbation, when expressed as a percentage of unperturbed EMG activity, were significantly smaller during Kohnstamm movements than during voluntary movements. The results suggest that the Kohnstamm aftercontraction involves a central drive, coupled with low-gain servo control by a negative feedback loop between afferent input and a central motor command. The combination of strong efferent drive with low reflex gain may characterize involuntary control of postural muscles. Our results question traditional accounts involving purely reflexive mechanisms of postural maintenance.

In this article, we propose an innovative method to track the sun using an image sensor. In our method, it is logical to assume the points of the brightest region in the sky image representing the location of the sun. Then, the center of the brightest region is assumed to be the solar-center, and is mathematically calculated using an embedded processor (Raspberry Pi). Finally, the location information on the sun center is sent to the embedded processor to control two servo motors that are capable of moving both horizontally and vertically to track the sun. In comparison with the existing sun tracking methods using image sensors, such as the Hough transform method, our method based on the brightest region in the sky image remains accurate under conditions such as a sunny day and building shelter. The practical sun tracking system using our method was implemented and tested. The results reveal that the system successfully captured the real sun center in most weather conditions, and the servo motor system was able to direct the photovoltaic panel perpendicularly to the sun center. In addition, our system can be easily and practically integrated, and can operate in real-time.","url":"https://pubmed.ncbi.nlm.nih.gov/27898002/","authors":["Wei CC","Song YC","Chang CC","Lin CB"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2016 Nov 25","doi":"10.3390/s16121995","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:37.819Z"},{"id":"pmid:27831937","name":"Minimalistic optic flow sensors applied to indoor and outdoor visual guidance and odometry on a car-like robot.","source":"pubmed","abstract":"Here we present a novel bio-inspired optic flow (OF) sensor and its application to visual &#xa0;guidance and odometry on a low-cost car-like robot called BioCarBot.

The system, which uses a Raspberry Pi as its primary microprocessor, uses a USB microphone to pick up voice instructions, giving the user control over a number of in- car features. To ensure safety when navigating, an ultrasonic sensor (HC-SR04) is employed to identify impediments. A DHT11 sensor provides environmental feedback by measuring temperature and humidity in real time, while a servo motor controls the car's windows. The direction of the vehicle is controlled by a motor driver, while audio output is provided by a speaker for notifications, song playback, and voice responses.

After identification the waste is automatically sorted into the correct container using a mechanism that combines servo and stepper motors ensuring accurate placement and better operational control. The model demonstrated a testing accuracy of 92%. Additionally the system supports real-time monitoring of bin levels and sends notifications when bins are full through the Blynk IoT mobile application. The proposed system reduces human intervention, improves segregation accuracy, and supports sustainable waste management, making it suitable for smart cities and public institutions in alignment with the Swachh Bharat Abhiyan and UN Sustainable Development Goals.","url":"https://doi.org/10.5281/zenodo.19733762","authors":["Dhiti Samrat Hingle","Bhumika Jadhav","Swarangi Jadhav","Prathamesh Ghogikar","Prof.  S.

Disinhibitory Circuits Link Short-Term Adaptation to Familiarity and Reward Learning in Visual Cortex","source":"preprints","abstract":"Sensory cortices filter repeated inputs through rapid adaptation over seconds and experience-driven learning over days. Although these forms of plasticity occur simultaneously, it is not known how they interact within cortical circuits. We combined two-photon calcium imaging, data-driven circuit modelling and optogenetics to investigate how short-term adaptation in layer 2/3 of mouse V1 is shaped by stimulus familiarity and reward association. Habituation reduced the fraction of pyramidal cells responsive to a visual stimulus, whereas reward association maintained overall responsivity. In contrast, both forms of learning shifted pyramidal cell adaptation from depression toward sensitization, but through distinct circuit mechanisms. Habituation reduced disinhibition through the VIP→SST→PC pathway by weakening feedback activation of VIPs and VIP→SST connections. Reward association counteracted this effect by increasing disinhibition through the SST→PV→PC pathway, strengthening SST→PV connections while reducing SST→PC inputs. Despite engaging distinct disinhibitory circuits and producing divergent effects on pyramidal cell responsivity, both forms of learning converged on a reduced PV:SST input ratio to pyramidal cells, thereby biasing V1 toward sensitizing adaptation. These results identify changes in cortical circuits that link the plasticity of fast adaptation to simple forms of learning.","url":"https://doi.org/10.64898/2026.03.24.713929","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.64898/2026.03.24.713929","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.22541/au.165237501.12388475/v1","name":"IoT

cognitive behavior in rodents, offering great flexibility and translational potential. The development of touchscreen assays presents a significant programming and mechanical engineering challenge, where commercial solutions can be prohibitively expensive and open-source solutions are underdeveloped, with limited adaptability. New method Here, we present Visiomode ( www.visiomode.org ), an open-source platform for building rodent touchscreen-based behavioral tasks. Visiomode leverages the inherent flexibility of touchscreens to offer a simple yet adaptable software and hardware platform. The platform is built on the Raspberry Pi computer combining a web-based interface and powerful plug-in system with an operant chamber that can be adapted to generate a wide range of behavioral tasks. Results As a proof of concept, we use Visiomode to build both simple stimulus-response and more complex visual discrimination tasks, showing that mice display rapid sensorimotor learning including switching between different motor responses (i.e., nose poke versus reaching). Comparison with existing methods Commercial solutions are the ‘go to’ for rodent touchscreen behaviors, but the associated costs can be prohibitive, limiting their uptake by the wider neuroscience community. While several open-source solutions have been developed, efforts so far have focused on reducing the cost, rather than promoting ease of use and adaptability. Visiomode addresses these unmet needs providing a low-cost, extensible platform for creating touchscreen tasks. Conclusions Developing an open-source, rapidly scalable and low-cost platform for building touchscreen-based behavioral assays should increase uptake across the science community and accelerate the investigation of cognition, decision-making and sensorimotor behaviors both in health and disease.","url":"https://doi.org/10.1101/2022.12.01.518732","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.1101/2022.12.01.518732","addedAt":"2026-08-31T06:34:37.819Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1101/2025.03.17.643718","name":"Light-field deep learning enables high-throughput, scattering-mitigated calcium imaging","source":"preprints","abstract":"Light field microscopy (LFM) enables volumetric, high throughput functional imaging.

Mechanosensitive enteric neurons (MEN) initiate reflex activity by responding to mechanical deformation of the gastrointestinal wall. MEN throughout the gut primarily respond to compression or stretch rather than to shear force. Some MEN are multimodal as they respond to compression and stretch. Depending on the region up to 60% of the entire ENS population responds to mechanical stress. MEN fire action potentials after mechanical stimulation of processes or soma although they are more sensitive to process deformation. There are at least two populations of MEN based on their sensitivity to different modalities of mechanical stress and on their firing pattern. (1) Rapidly, slowly and ultra-slowly adapting neurons which encode compressive forces. (2) Ultra-slowly adapting stretch-sensitive neurons encoding tensile forces. Rapid adaptation of firing is typically observed after compressive force while slow adaptation or ongoing spike discharge occurs often during tensile stress (stretch). All MEN have some common properties: they receive synaptic input, are low fidelity mechanoreceptors and are multifunctional in that some serve interneuronal others even motor functions. Consequently, MEN possess processes with mechanosensitive as well as efferent functions. This raises the intriguing hypothesis that MEN sense and control muscle activity at the same time as servo-feedback loop. The mechanosensitive channel(s) or receptor(s) expressed by the different MEN populations are unknown. Future concepts have to incorporate compressive and tensile-sensitive MEN into neural circuits that controls muscle activity.

Previous modeling and experimental studies of bouncing gait (e.g., walking, running, hopping) identified muscle-tendon interactions that cycle large amounts of energy in series tendon as a source of elastic limb behavior. The neural, biomechanical, and environmental origins of these tuned mechanics, however, have remained elusive. To examine the dynamic interplay between these factors, we developed an experimental platform comprised of a feedback-controlled servo-motor coupled to a biological muscle-tendon. Our novel motor controller mimicked in vivo inertial/gravitational loading experienced by muscles during terrestrial locomotion, and rhythmic patterns of muscle activation were applied via stimulation of intact nerve. This approach was based on classical workloop studies, but avoided predetermined patterns of muscle strain and activation-constraints not imposed during real-world locomotion. Our unconstrained approach to position control allowed observation of emergent muscle-tendon mechanics resulting from dynamic interaction of neural control, active muscle, and system material/inertial properties. This study demonstrated that, despite the complex nonlinear nature of musculotendon systems, cyclic muscle contractions at the passive natural frequency of the underlying biomechanical system yielded maximal forces and fractions of mechanical work recovered from previously stored elastic energy in series-compliant tissues. By matching movement frequency to the natural frequency of the passive biomechanical system (i.e., resonance tuning), muscle-tendon interactions resulting in spring-like behavior emerged naturally, without closed-loop neural control.

Furthermore, it is difficult for small residual stumps to provide sufficient impact absorption for safe manipulation in daily living, as intact arms do. Therefore, substitution of upper limb function in transhumeral amputees requires a sufficient range of motion and sufficient viscoelasticity for shoulder prostheses under critical weight and dimension constraints. We propose the use of two different types of actuators, ie, pneumatic elastic actuators (PEAs) and servo motors. PEAs offer high power-to-weight performance and have intrinsic viscoelasticity in comparison with motors or standard industrial pneumatic cylinder actuators. However, the usefulness of PEAs in large working spaces is limited because of their short strokes. Servo motors, in contrast, can be used to achieve large ranges of motion. In this study, the relationship between the force and stroke of PEAs was investigated. The impact absorption of both types of actuators was measured using a single degree-of-freedom prototype to evaluate actuator compliance for safety purposes. Based on the fundamental properties of the actuators identified, a four degree-of-freedom robotic arm is proposed for prosthetic use.

However, due to measurement limitation a kinetic understanding of the foot-ground collision and how these dynamics differ between individuals to confer speed and limit gait has only recently begun to come forth. Therefore, we designed and tested an instrumented high-speed force treadmill to measure the forces occurring at the limits of human performance. The treadmill was designed to maximize flexural stiffness and natural frequency by using a honeycomb sandwich panel as the bed surface and a flexible drive shaft between the drive roller and servo motor to reduce the mass of the supported elements which contribute to the system's response frequency. The functional performance of the force treadmill met or exceeded the measurement criteria established for ideal force plates: high natural frequency (z-axis = 113 Hz), low crosstalk between components of the force (Fx/Fz = 0.0020[SD = 0.0010]; Fy/Fz = 0.0016[SD = 0.0003]), a linear response (R(2) &gt; 0.999) for loading with known weights (range: 44-3857 N), and an accuracy of 2.5[SD = 1.7] mm and 2.8[SD = 1.5] mm in the x and y-axes, respectively, for the point of force application. In dynamic testing at running speeds up to 10 m s(-1), the measured durations and magnitudes of force application were similar between the treadmill and over-ground running using a force platform.

The aim of this study was to gain a better understanding of the neural networks underlying adaptation of postural responses within PwMS. Participants stood on a hydraulically driven, servo-controlled platform that translated horizontally forward and backward in a continuous sinusoidal pattern across multiple trials over two consecutive days. Our results show similar postural adaptation between PwMS and age-matched control participants despite overall deficits in postural motor control in PwMS. Moreover, PwMS demonstrated better retention the following day. PwMS had significantly reduced functional connectivity within both the cortico-cerebellar and cortico-striatal motor loops; neural networks that subserve implicit motor learning. In PwMS, greater connectivity strength within the cortico-cerebellar circuit was strongly related to better baseline postural control, but not to postural adaptation as it was in control participants. Further, anti-correlated cortico-striatal connectivity within the right hemisphere was related to improved postural adaptation in both groups. Taken together with previous studies showing a reduced reliance on cerebellar- and proprioceptive-related feedback control in PwMS, we suggest that PwMS may rely on cortico-striatal circuitry to a greater extent than cortico-cerebellar circuitry for the acquisition and retention of motor skills.","url":"https://pubmed.ncbi.nlm.nih.gov/26106552/","authors":["Fling BW","Gera Dutta G","Horak FB"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2015","doi":"10.1016/j.nicl.2015.04.023","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:25748966","name":"Fatigue in patients with multiple sclerosis: from movement preparation to motor execution.","source":"pubmed","abstract":"The neural mechanisms underlying fatigue in multiple sclerosis (MS) are still poorly understood.

The study of CMC in this specific band is of particular interest because this coherence is usually absent in healthy individuals and it is an aberrant feature in patients affected by pathological tremors; understanding its mechanisms is therefore important. Thirteen healthy volunteers (23&#xb1;4 years) performed elbow flexor sustained contractions both against a spring load and in isometric conditions at 20% of maximal voluntary isometric contraction (MVC). Spring stiffness was selected to induce instability in the stretch reflex servo loop. 64 EEG channels, surface EMG from the biceps brachii muscle and force were simultaneously recorded. Contractions against the spring resulted in greater fluctuations of the force signal and EMG amplitude compared to isometric conditions (p&lt;.05). During isometric contractions CMC was systematically found in the beta band and sporadically observed in the alpha band. However, during the contractions against the spring load, CMC in the alpha band was observed in 12 out of 13 volunteers. Partial directed coherence (PDC) revealed an increased information flow in the EMG to EEG direction in the alpha band (p&lt;.05). Therefore, coherence in the alpha band between the sensory-motor cortex and the biceps brachii muscle can be systematically induced in healthy individuals by mechanically amplifying tremor. The increased information flow in the EMG to EEG direction may reflect enhanced afferent activity from the muscle spindles. These results may contribute to the understanding of the presence of alpha band CMC in tremor related pathologies by suggesting that the origin of this phenomenon may not only be at cortical level but may also be affected by spinal circuit loops.","url":"https://pubmed.ncbi.nlm.nih.gov/25514444/","authors":["Budini F","McManus LM","Berchicci M","Menotti F","Macaluso A","Di Russo F","Lowery MM","De Vito G"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2014","doi":"10.1371/journal.pone.0115012","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:25226929","name":"Analysis of antagonistic co-contractions with motorized passive movement device in patients with Parkinson's disease.","source":"pubmed","abstract":"Patients with Parkinson's disease (PD) suffer from an increased resistance to passive movement of a joint, called as rigidity.

It consisted of a servo motor connected to a rotating axis with a timing belt, load cell for the measurement of resistance, and other elements for the fixation of arm and hand. Repetitive passive movement was applied to the wrist joint of patients. Co-contraction of antagonistic muscle pairs was significantly greater in patients than in normal subjects (p&lt;0.001), suggesting that the enhanced co-contraction is associated with the mechanical resistance during passive movement, i.e. rigidity.

In particular, a toroidal search algorithm is applied to the laser cavity for various birefringence values by varying the waveplate and polarizer angles at incommensurate angular frequencies, thus producing a time-series of the objective function. The resulting time series, which is converted to a spectrogram and then dimensionally reduced with a singular value decomposition, is then labelled with the corresponding effective birefringence and concatenated into a library of modes. A sparse search algorithm (L(1)-norm optimization) is then applied to a test measurement in order to classify the birefringence of the fiber laser. Simulations show that the sparse search algorithm performs very well in recognizing cavity birefringence even in the presence of noise and/or noisy measurements.

The modeling errors of the LPM and the QPIM are investigated by experiments. The modeling error of the LPM presents an obvious trend component which is about &#xb1;1.15% of the full span range verifying the efficiency of the proposed OSaRDE algorithm for system identification. As for the QPIM, the trend component in the residual error of LPM can be well suppressed, and the error of the QPIM maintains noise level. All the results verify the efficiency and superiority of the proposed modeling and identification approaches.","url":"https://pubmed.ncbi.nlm.nih.gov/24163627/","authors":["Liu Q","Zhou X","Lin J","Xu P","Zhu Z"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2013","doi":"10.1155/2013/641269","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:24161387","name":"Physiological responses to spinal manipulation therapy: investigation of the relationship between electromyographic responses and peak force.","source":"pubmed","abstract":"It is believed that systematic modulation of spinal manipulative therapy (SMT) parameters should yield varying levels of physiological responses and eventually a range of clinical responses.

FBot implements a symmetric gait using two servo-motor-driven front limbs with flat-plate flippers and either freely rotating or fixed wrist joints. For a range of gaits, FBot moves with a constant step length. However, for gaits with sufficiently shallow flipper penetration or sufficiently large stroke, per step displacement decreases with each successive step resulting in failure (zero forward displacement) within a few steps. For the fixed wrist, failure occurs when FBot interacts with ground disturbed during previous steps, and measurements reveal that flipper generated forces decrease as per step displacement decreases. The biologically inspired free wrist is less prone to failure, but slip-induced failure can still occur if FBot pitches forward and drives its leading edge into the substrate. In the constant step length regime, kinematic and force-based models accurately predict FBot's motion for free and fixed wrist configurations, respectively. When combined with independent force measurements, models and experiments provide insight into how disturbed ground leads to locomotory failure and help explain differences in hatchling sea turtle performance.","url":"https://pubmed.ncbi.nlm.nih.gov/23612858/","authors":["Mazouchova N","Umbanhowar PB","Goldman DI"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2013 Jun","doi":"10.1088/1748-3182/8/2/026007","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:23522686","name":"Exploratory data analysis for robot perception of room environments by means of an in-air sonar scanner.","source":"pubmed","abstract":"In this paper, the authors have developed a new method for reconstructing the boundary walls of a room environment by using a mechatronic device consisting of four ultrasonic sensors rotated by a servo modular actuator.

In five anesthetized rabbits, muscle blood flow was continuously monitored in the masseteric artery, bilaterally (n = 10). Hyperaemic responses were evoked by compressive stimuli of different extent (50, 100 and 200 mm Hg) and duration (0.5, 1, 2 and 5 s) exerted by a servo-controlled motor on the masseter muscle. Peak amplitude of the hyperaemic response ranged from 340 &#xb1; 30% of baseline (at 50 mm Hg) to 459 &#xb1; 57% (at 200 mm Hg) (P &lt; 0.05), did not depend on stimulus duration and exhibited very good reliability (ICC = 0.98) when reassessed at 30 min intervals.

In conclusion, for its high sensitivity and reliability this technique is adequate to characterize mechano-vascular reactivity and may prove useful in the investigation of the underlying mechanisms, with implications in the control of vascular tone and blood pressure in health and disease.","url":"https://pubmed.ncbi.nlm.nih.gov/23399827/","authors":["Turturici M","Roatta S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2013 Mar","doi":"10.1088/0967-3334/34/3/307","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:27158179","name":"Physiologically gated micro-beam radiation therapy using electronically controlled field emission x-ray source array.","source":"pubmed","abstract":"Micro-beam radiation therapy (MRT) uses parallel planes of high dose narrow (10-100 um in width) radiation beams separated by a fraction of a millimeter to treat cancerous tumors.

J Neurosci 31: 16907-16915, 2011). Here, we tested whether motor learning could be improved by providing subjects with proprioceptive training on a desired hand trajectory. Subjects were instructed to reproduce both the time-varying position and velocity of novel, complex hand trajectories. Subjects underwent 3 days of training with 90 movement trials per day. Active movement trials were interleaved with demonstration trials. For control subjects, these interleaved demonstration trials consisted of visual demonstration alone. A second group of subjects received visual and proprioceptive demonstration simultaneously; this group was presented with the same visual stimulus, but, in addition, their limb was moved through the target trajectory by a robot using servo control. Subjects who experienced the additional proprioceptive demonstration of the desired trajectory showed greater improvements during training movements than control subjects who only received visual information.

In the baseline, static condition, the arm of the participants remained stationary. In the passive condition, the arm was displaced by a servo-controlled motorized device. In the active condition, the participants moved voluntarily. The auditory stimulus was a short, 500Hz tone presented over headphones and the haptic stimulus was a brief suprathreshold force pulse applied to the tip of the index finger orthogonally to the finger movement. Active movement did not significantly affect discrimination sensitivity on the auditory-haptic stimulus pairs, whereas it significantly improved sensitivity in the case of the haptic stimulus pair, demonstrating a key role for motor command information in temporal sensitivity in the haptic system. Points of subjective simultaneity were by-and-large coincident with physical simultaneity, with one striking exception in the passive condition with the auditory-haptic stimulus pair. In the latter case, the haptic stimulus had to be presented 45ms before the auditory stimulus in order to obtain subjective simultaneity.

Though each of these strategies may contribute to joint stability, it is unclear how their relative contribution varies when ankle stability is threatened. We addressed this question by characterizing co-contraction and stretch reflexes during balance of an inverted pendulum simulated by a rotary motor configured as an admittance servo. The stability of this haptic environment was manipulated by varying the stiffness of a virtual spring supporting the pendulum. We hypothesized that co-contraction and stretch reflex amplitude would increase as the stability of the haptic load attached to the ankle was reduced. Electromyographic activity in soleus, medial and lateral gastrocnemius, and tibialis anterior was used to characterize co-contraction patterns and stretch reflex amplitude as subjects stabilized the haptic load. Our results revealed that co-contraction was heightened as stability was reduced, but that the resulting joint stiffness was not sufficient to fully counteract the imposed instability. Reflex amplitude, in comparison, was attenuated as load stability was reduced, contrary to results from upper limb studies using similar paradigms. Together these findings suggest that the nervous system utilizes feed-forward co-contraction rather than rapid involuntary feedback to increase ankle stability during simple balance tasks. Furthermore, since the stiffness generated through co-contraction was not sufficient to fully balance the haptic load, our results suggest an important role for slower, volitional feedback in the control of ankle stability during balancing tasks.","url":"https://pubmed.ncbi.nlm.nih.gov/22169978/","authors":["Finley JM","Dhaher YY","Perreault EJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2012 Mar","doi":"10.1007/s00221-011-2972-9","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:22077383","name":"Development of a measurement and feedback training tool for the arm strokes of high-performance luge athletes.","source":"pubmed","abstract":"Previous studies have shown that the start plays a critical role in sliding events and explains more than 55% of the variance of the final time in luge.

Eye movements were recorded by binocular video-oculography, and a servo-controlled rotary chair produced vestibular stimulation.

Individuals with DS displayed small alterations in the VOR gain and dynamics compared to controls. In contrast, the number of VOR nystagmus beats and the ability to inhibit the VOR by visual target fixation were markedly and robustly smaller in persons with DS. Significantly increased VOR adaptation was observed in men with DS.

Recently, continuous, optimal control using internal models has emerged as a leading paradigm for voluntary movement. However, these engineering paradigms are designed for high band-width, inflexible, consistent systems whereas human control is low bandwidth and flexible using noisy sensors and actuators. By contrast, engineering intermittent control was designed for bandwidth-limited applications. Our general interest is whether intermittent rather than continuous control is generic to human motor control. Currently, it would be assumed that continuous control is the superior and physiologically natural choice for controlling unstable loads, for example as required for maintaining human balance. Using visuo-manual tracking of an unstable load, we show that control using gentle, intermittent taps is entirely natural and effective. The gentle tapping method resulted in slightly superior position control and velocity minimisation, a reduced feedback time delay, greater robustness to changing actuator gain and equal or greater linearity with respect to the external disturbance. Control was possible with a median contact rate of 0.8&#xb1;0.3 s(-1). However, when optimising position or velocity regulation, a modal contact rate of 2 s(-1) was observed. This modal rate was consistent with insignificant disturbance-joystick coherence beyond 1-2 Hz in both tapping and continuous contact methods. For this load, these results demonstrate a motor control process of serial ballistic trajectories limited to an optimum rate of 2 s(-1). Consistent with theoretical reasoning, our results suggest that intermittent open loop action is a natural consequence of human physiology.","url":"https://pubmed.ncbi.nlm.nih.gov/21098004/","authors":["Loram ID","Gollee H","Lakie M","Gawthrop PJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2011 Jan 15","doi":"10.1113/jphysiol.2010.194712","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:20802114","name":"Are fish less responsive to a flow stimulus when swimming?","source":"pubmed","abstract":"Fish use the lateral line system to sense the water flow created by a predator's strike.

Therefore, the present study compared the behavioral responsiveness of swimming and motionless zebrafish (Danio rerio) larvae when exposed to the flow of a suction-feeding predator. This flow was generated with an impulse chamber, which is a device that we developed to generate a repeatable stimulus with a computer-controlled servo motor. Using high-speed video recordings, we found that about three-quarters (0.76, N=121) of motionless larvae responded to the stimulus with an escape response. These larvae were 66% more likely to respond to flow directed perpendicular than flow running parallel to the body. Swimming larvae exhibited a 0.40 response probability and were therefore nearly half as likely to respond to flow as motionless larvae. However, the latency between stimulus and response was unaffected by swimming or the direction of flow. Therefore, swimming creates changes in the hydrodynamics or neurophysiology of a larval fish that diminish the probability, but not the speed, of their response to a flow stimulus.

A dual high-order periodic adaptive learning compensation (DHO-PALC) method is proposed to minimize the cogging effect on the PMSM position and velocity servo system. In this DHO-PALC scheme, more than one previous periods stored information of both the composite tracking error and the estimate of the cogging force is used for the control law updating. Asymptotical stability proof with the proposed DHO-PALC scheme is presented. Simulation is implemented on the PMSM servo system model to illustrate the proposed method.

Moreover, when the designed reference signal changes periodically, the proposed DHO-PALC can obtain not only faster convergence speed, but also much smaller final error bound than the FO-PALC.","url":"https://pubmed.ncbi.nlm.nih.gov/20605022/","authors":["Luo Y","Chen Y","Pi Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2010 Oct","doi":"10.1016/j.isatra.2010.05.003","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:20205249","name":"Somatosensory-evoked cortical activity in spastic diplegic cerebral palsy.","source":"pubmed","abstract":"Somatosensory deficits have been identified in cerebral palsy (CP), but associated cortical brain activity in CP remains poorly understood.

Over the last two decades optical traps have helped uncover the working principles of conventional molecular motors, such as kinesin and dynein, but only recently have they been applied to study kinetochore function. The most useful traps combine sensitive position detectors and servo-control, allowing them to be operated as force clamps that maintain constant loads on objects as they move. Our instrument, which is among the simplest designs that permits force clamping, relies on a computer-controlled piezoelectric stage and a single laser for trapping and position detection. We apply it in motility assays where beads coated with pure microtubule-binding kinetochore components are attached to the tips of individual dynamic microtubules. Like kinetochores in vivo, the beads remain tip-attached, undergoing movements coupled to filament assembly and disassembly. The force clamp provides many benefits over instruments that lack feedback control. It allows tension to be applied continuously during both assembly- and disassembly-driven movement, providing a close match to the physiological situation. It also enables tracking with high resolution, and simplifies data interpretation by eliminating artifacts due to molecular compliance. The formation of persistent, load-bearing attachments to dynamic microtubule tips is fundamental to all kinetochore activities. Our direct, physical study of kinetochore-microtubule coupling may therefore furnish insights into many vital kinetochore functions, including correction of aberrant attachments and generation of the 'wait-anaphase' signals that delay mitosis until all kinetochores are properly attached.","url":"https://pubmed.ncbi.nlm.nih.gov/20096784/","authors":["Franck AD","Powers AF","Gestaut DR","Davis TN","Asbury CL"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2010 Jun","doi":"10.1016/j.ymeth.2010.01.020","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:19964884","name":"Development and feasibility study of a sensory-enhanced robot-aided motor training in stroke rehabilitation.","source":"pubmed","abstract":"Functional impairment of the upper limb is a major challenge faced by many stroke survivors.

In both cases, clinical descriptions have been retrieved from written documents predating Gilles de la Tourette's original publication. The case for Samuel Johnson having GTS is strong, mainly based on Boswell's extensive biographical account. Johnson was reported to have a great range of tics and compulsions, including involuntary utterances, repetitive ejaculations, and echo-phenomena. On the other hand, there is circumstantial evidence that Mozart may have had hyperactivity, restlessness, sudden impulses, odd motor behaviors, echo/palilalia, love of nonsense words, and scatology, the latter being documented in autograph letters (\"coprographia\"). However, the evidence supporting the core features of GTS, i.e., motor and vocal tics, is rather inconsistent. Thus, GTS seems to be an implausible diagnosis in Mozart's medical history and completely unrelated to his undisputed musical genius.","url":"https://pubmed.ncbi.nlm.nih.gov/19913652/","authors":["Monaco F","Servo S","Cavanna AE"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2009 Dec","doi":"10.1016/j.jpsychores.2009.07.003","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:19883908","name":"An optimization study of the motion table performance.","source":"pubmed","abstract":"This paper investigates the optimal selection of processing parameters for motion table performance.

The resulting reflexes and mechanical changes in the RA affected joint were explored. Surface electromyographic (EMG) measurements were obtained from first dorsal interosseus muscle.

The decreased reflex gain was most evident at high stretch frequency suggesting a disproportionate loss of the large diameter afferent response and also increased reflex delay in the patients.

Here, we show that this correlation holds when subjects are explicitly instructed to move at less than maximal speed. We studied elbow flexion movements made at maximal speed and at 70% of maximal speed over a short distance against a light inertial load and over a long distance against a heavy inertial load. A small number of trials were unexpectedly perturbed by using a servo-controlled motor to decrease the movement velocity. The servo control was turned on early in the movement. The main novel finding is that responses in the surface EMG in the elbow muscles to the perturbation occurred later in the slow-speed conditions than fast-speed conditions. When viewed across all conditions, the onset of the EMG responses to the perturbation increased with the time to peak acceleration in unperturbed movements. In the inertial loaded movements, the time of peak acceleration coincides with the time of peak inertial torque, and so the observed correlation can be interpreted as reflecting the relation between either the planned movement kinematics or the planned movement dynamics. These results are compatible with a hypothesis that a descending command suppresses the proprioceptive feedback control at the movement onset and facilitates it at a time that depends on the time parameters of the planned movement.","url":"https://pubmed.ncbi.nlm.nih.gov/19701630/","authors":["David FJ","Poon C","Niu CM","Corcos DM","Shapiro MB"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2009 Oct","doi":"10.1007/s00221-009-1967-2","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:19663719","name":"Stem cells in amyotrophic lateral sclerosis: state of the art.","source":"pubmed","abstract":"Amyotrophic lateral sclerosis (ALS) is a devastating incurable neurodegenerative disease that targets motor neurons, manifesting as a linear decline in muscular function and leading to death within 2 - 5 years of diagnosis.

Surface electrodes were attached over the biceps of the more severely affected arm and a reference electrode attached to the back of the contra-lateral hand. EMG data was normalized using the rest mean EMG level and then segmented into epochs according to the position data. EMG recorded from normal subjects remained flat throughout the trial with only very small fluctuations in amplitude about the mean. In contrast, biceps activity in parkinsonian patients tended to increase with flexion and as expected there were large variations in amplitude about the baseline activity. A fast fourier transform was also performed and spectra obtained from a typical Parkinsonian patient showed two peaks at approximately 6 Hz and 8 Hz, consistent with previously published data. In conclusion, the results clearly differentiate between normal and parkinsonian cases and to some extent severity. Quantification of disease severity might be possible given a broader range and greater number of patients.","url":"https://pubmed.ncbi.nlm.nih.gov/19163293/","authors":["Wright D","Nakamura K","Maeda T","Kutsuzawa K","Miyawaki K","Nagata K"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2008","doi":"10.1109/IEMBS.2008.4649790","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:19163216","name":"Focused ultrasound thermal therapy system with ultrasound image guidance and temperature measurement feedback.","source":"pubmed","abstract":"In this study, we developed a focused ultrasound (FUS) thermal therapy system with ultrasound image guidance and thermocouple temperature measurement feedback.

The entire system integrated automatic position devices, FUS transducer, power amplifier, ultrasound image system, and thermocouple temperature measurement into a graphical user interface. For the treatment procedure, a thermocouple was implanted into a targeted treatment region in a tissue-mimicking phantom under ultrasound image guidance, and then the acoustic interference pattern formed by image ultrasound beam and low-power FUS beam was employed as image guidance to move the FUS transducer to have its focal zone coincident with the thermocouple tip. The thermocouple temperature rise was used to determine the sonication duration for a suitable thermal lesion as a high power was turned on and ultrasound image was used to capture the thermal lesion formation. For a multiple lesion formation, the FUS transducer was moved under the acoustic interference guidance to a new location and then it sonicated with the same power level and duration. This system was evaluated and the results showed that it could perform two-dimensional motion control to do a two-dimensional thermal therapy with a small localization error 0.5 mm. Through the user interface, the FUS transducer could be moved to heat the target region with the guidance of ultrasound image and acoustic interference pattern.

The intact pelves were fixed to a load cell with a custom aluminum pot placed around the sacrum. Special care was taken when potting the pelves in order to ensure that the orientation of the pelves was representative of that seen in normal upright seating. The pelves were then subjected to dynamic compressive loading at a rate of approximately 2 m/s using a servo-hydraulic Material Testing System (MTS). The average peak force, moment, and displacement at the point of failure were 5,896 +/- 1455 N, 33.4 +/- 28.6 N-m, and 6.4 +/- 0.7 mm, respectively. The failure of the all pelvis specimens corresponded to a bilateral dislocation of the sacroiliac joint. As a general trend, strain gage data showed that the right and left superior ramus were placed in tension and the right and left ischium were placed in compression. The peak strain values ranged from 746 mstr to 5717 mstr in tension and from -356 mstr to -2677 mstr in compression.

EMG electrodes were implanted bilaterally in selected muscles. Using a servo-controlled body weight support system for bipedal stepping, five rats were trained 7 d/week for 6 weeks (30 min/d) under quipazine (0.3 mg/kg) and ES (L2; 40 Hz).

Three trained and three nontrained rats stepped for 1 h (ES; no quipazine) and were returned to their cages for 1 h before intracardiac perfusion. All rats could step with ES and quipazine administration. The trained rats had higher and longer steps, narrower base of support at stance, and lower variability in EMG parameters than nontrained rats, and these properties approached that of noninjured controls. After 1 h of stepping, the number of FOS+ neurons was significantly lower in trained than nontrained rats throughout the extent of the lumbosacral segments.

This article provides a brief review of the dominant conceptual frameworks used to interpret MI activity, notably servo-control during the 1970s and early 1980s, and sensorimotor transformations since that time. The former emphasized the use of feedback, but was abandoned because delays in sensory feedback could not permit sufficient feedback gains to generate observed patterns of limb movement. The latter framework focuses attention on identifying what coordinate frames, or representations, best describe neural processing in MI. However, studies have shown that MI activity correlates with a broad range of parameters of motor performance from spatial target location, hand or joint motion, joint torque and muscle activation patterns. Further, these representations can change across behaviours, such as from posture to movement. What do heterogeneous, labile neural representations mean and how do they help us understand how MI is involved in volitional motor control? Perhaps what is required is a new conceptual framework that re-focuses the experimental problem back on processes of control. Specifically, optimal feedback control has been proposed as a theory of the volitional motor system and it is argued here that it provides a rich, new perspective for addressing the role of MI and other brain regions in volitional motor control.","url":"https://pubmed.ncbi.nlm.nih.gov/18187462/","authors":["Scott SH"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2008 Mar 1","doi":"10.1113/jphysiol.2007.146068","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:17946282","name":"Tendon reflexes elicited using a computer controlled linear motor tendon hammer.","source":"pubmed","abstract":"We present a novel instrumentation system for studying tendon and spinal reflexes using a commercial linear servo-motor as a precisely controlled tendon hammer.

Mechanically evoked activity in the orbicularis oris muscles was studied in young human female adults (N=10) during a lip force recruitment task associated with the repetition of the nonsense speech utterance \"ah-wah.\" This speech task involved the recruitment of perioral motor units against an elastic load. A skin contactor probe coupled to a servo-controlled linear motor delivered punctate ipsilateral mechanical inputs (25 ms duration, 1800 mum displacement) to the glabrous surface of the upper lip in order to index the modulation and specificity of the compound trigeminofacial response as a function of speech force recruitment threshold (Ft). Modulation of the early (Ft=0.2 N) and later (Ft=1.0 N) components of the evoked perioral response was found at the two force thresholds.

Variation in the lip force trajectories was manifest by a greater difference in net interangle force associated with lip perturbations indexed to the early Ft. This was interpreted to reflect the operation of a feedforward mechanism which may play a more significant role during an evolving speech action.

Such customization is mostly ignored by traditional theories emphasizing movement geometry and servo control. In contrast, the relationship between the task and the strategy most suitable for accomplishing it lies at the core of our optimal feedback control theory of coordination. Here, we show that the predicted sensitivity to task goals affords natural explanations to a number of novel psychophysical findings. Our point of departure is the little-known fact that corrections for target perturbations introduced late in a reaching movement are incomplete. We show that this is not simply attributable to lack of time, in contradiction with alternative models and, somewhat paradoxically, in agreement with our model. Analysis of optimal feedback gains reveals that the effect is partly attributable to a previously unknown trade-off between stability and accuracy. This yields a testable prediction: if stability requirements are decreased, then accuracy should increase. We confirm the prediction experimentally in three-dimensional obstacle avoidance and interception tasks in which subjects hit a robotic target with programmable impedance. In additional agreement with the theory, we find that subjects do not rely on rigid control strategies but instead exploit every opportunity for increased performance. The modeling methodology needed to capture this extra flexibility is more general than the linear-quadratic methods we used previously. The results suggest that the remarkable flexibility of motor behavior arises from sensorimotor control laws optimized for composite cost functions.","url":"https://pubmed.ncbi.nlm.nih.gov/17728449/","authors":["Liu D","Todorov E"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2007 Aug 29","doi":"10.1523/JNEUROSCI.1110-06.2007","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:17712294","name":"A precision translation stage for reproducing measured target volume motions.","source":"pubmed","abstract":"The development of 4D imaging, treatment planning and treatment delivery methods for radiation therapy require the use of a high-precision translation stage for testing and validation.

A third linear motor is vertically oriented, and permits the rapidly dropping chamber to smoothly decelerate. All movements were performed by the three motors and four solenoids controlled by a PC. Mechanical adjustments, that change the size of the gap between the hammers at the end position, permit the final thickness of the frozen tissue to be varied. Here we show that the freezing time increased with the square of the final thickness of the frozen bundle. However, when bundles of different original thicknesses (up to at least 1mm) were compressed to the same final thickness (e.g., 0.2mm), they exhibited nearly equal freezing times. Hence, by being able to adjust the final thickness of the frozen bundles, the device not only speeds the rate of freezing, but standardizes the freezing time for different diameter samples. This permits the use of freezing for accurate determination of the kinetics of cellular processes in biological tissue.","url":"https://pubmed.ncbi.nlm.nih.gov/17640628/","authors":["Tikunov BA","Rome LC"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2007 Oct","doi":"10.1016/j.cryobiol.2007.06.002","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:17281861","name":"New shape memory alloy actuator: design and application in the prosthetic hand.","source":"pubmed","abstract":"This paper describes a new SMA actuator design and its application in the prosthetic hand replacing conventional servo motors which are bulky and noisy in nature.

Using a specialized set-up mechanically analogous to real standing, subjects manually balanced inverted pendulums with different moments of inertia through a compliant spring representing the Achilles tendon. The spring bias was controlled by a sensitive joystick via a servo motor and accurate visual feedback was provided on an oscilloscope. As moment of inertia decreased, inverted pendulum sway size increased and it became difficult to sustain successful balance. The mean duration of unidirectional balance adjustments did not change. Moreover, the mean duration of unidirectional inverted pendulum sway reduced only slightly, remaining around 1 s. The simplest explanation is that balance was maintained by a process of manual adjustments intrinsically limited to a mean frequency of two to three unidirectional adjustments per second corresponding to intermittent control observed in manual tracking experiments. Consequently the inverted pendulum sway duration, mechanically related to the bias duration, reflects an intrinsic constraint of the neuromuscular control system. Given the similar durations of sway and muscle adjustments observed in real standing, we postulate that the characteristic duration of unidirectional standing sway reflects intrinsic intermittent control rather than the inertial properties of the body.","url":"https://pubmed.ncbi.nlm.nih.gov/16973712/","authors":["Loram ID","Gawthrop PJ","Lakie M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2006 Nov 15","doi":"10.1113/jphysiol.2006.118786","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:16480110","name":"Loop shaping design for tracking performance in machine axes.","source":"pubmed","abstract":"A modern interpretation of classical loop shaping control design methods is presented in the context of tracking control for linear motor stages.

It was precipitated by a recent investigation in the cat showing that-contrary to the general assumption-post-activation depression is not a widespread phenomenon in the spinal cord. In 24 healthy subjects comparison was made between the effects of low and high-test stimulus rates on the monosynaptic Ia excitation, known to be subject to post-activation depression, and on oligosynaptic pathways fed by group I afferents. Both the amplitude of monosynaptic H reflexes and the amount of heteronymous monosynaptic Ia facilitation were significantly smaller at high than at low-test stimulus rates (1-2 s compared with 6-8 s between two consecutive stimuli). So was the amount of reciprocal Ia inhibition of tibialis anterior motoneurones. In contrast, the amount of other non-monosynaptic group I effects directed to the same motor nuclei (peroneal-induced excitation of quadriceps motoneurones, disynaptic non-reciprocal group I inhibition of flexor carpi radialis motoneurones, and D1 inhibition of flexor carpi radialis and soleus H reflexes) were enhanced at high stimulus rates. Results in humans confirm that post-activation depression depends on the type of group I afferents, and/or on the target neurones.

Surface electromyogram electrodes were placed over the left or right masseter, and subjects ( n=10) bit on bars with their incisor teeth at 10% of maximal electromyographic activity (EMG). Servo-controlled displacements were imposed on the lower jaw to evoke a short- and long-latency stretch reflex in masseter. TMS intensity was just suprathreshold for a response in contralateral masseter. Trials consisted of: (1) stretch alone, (2) TMS alone, and (3) TMS with a preceding conditioning stretch at varied conditioning-testing (C-T) intervals chosen to combine TMS with the short-latency stretch reflex (3 ms, 5 ms) and the LLSR (23-41 ms). Masseter EMG was rectified and averaged. With TMS alone, mean (+/- SE) MEP area above baseline was 56+/-9%. The area of masseter MEPs above baseline in the C-T trials was calculated from each EMG average following subtraction of the response to stretch alone. Conditioning muscle stretch had no significant effect on masseter MEPs evoked by TMS with any C-T interval (ANOVA; P=0.90). In addition, subjects were unable to modify the SLSR or LLSR by voluntary command. It is concluded that the long-latency stretch reflex in the masseter does not involve the motor cortex and is not influenced by \"motor set\".","url":"https://pubmed.ncbi.nlm.nih.gov/12712307/","authors":["Pearce SL","Miles TS","Thompson PD","Nordstrom MA"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2003 Jun","doi":"10.1007/s00221-003-1467-8","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:12662757","name":"Visually guided movements: learning with modular neural maps in robotics.","source":"pubmed","abstract":"Robotics involves complex processing and requires modular controllers.

Sway-referencing disrupted somatosensory feedback for postural control by servo-controlling the dorsi- and plantar-flexion rotation of the support surface in proportion to anterior-posterior excursion of (1) ankle angle, (2) center of body mass (CoM) angle or (3) filtered center of pressure (CoP).

Control subjects standing on any sway-referenced surface swayed significantly more than neuropathy subjects who stood on a firm surface, suggesting that sway-referencing disrupts more somatosensory information than disrupted by severe neuropathy. CoP sway-referencing was less sensitive than ankle or CoM sway-referencing for distinguishing postural sway in subjects with somatosensory loss from age-matched control subjects. Given that filtered CoP sway-referencing disrupts the ability to utilize somatosensory information related to surface reactive force to a greater extent than the other two methods of sway-referencing, then these results support the hypothesis that subjects with diabetic peripheral neuropathy have lost more CoP information, than ankle or CoM angle information, for controlling postural sway in stance.","url":"https://pubmed.ncbi.nlm.nih.gov/12590833/","authors":["Horak FB","Dickstein R","Peterka RJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2002","doi":"10.1080/0899022021000037782","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:12583146","name":"[An integrated medical diagnostic X-ray unit controlled by microcomputer].","source":"pubmed","abstract":"This article introduces an integrated medical diagnostic X-ray unit controlled by microcomputer.

Lesion data from monkeys suggest that these vergence responses are mediated, at least in part, by neurons in the medial superior temporal area of the cerebral cortex, and we here review a recent study of the associated single unit activity in that area. Few medial superior temporal neurons have disparity tuning curves whose shapes resemble the tuning curve for vergence.

Sudden release of the magnets on three sides of the platform (leaving one side attached) induces rotational perturbations in either the pitch or roll plane.

Eight right-handed subjects actively tracked a driven hand being flexed and extended by a computer-controlled AC servo-motor. Hand movements were constrained in flexion or extension. The simultaneous contraction of wrist flexors and extensors was defined as inphase (IP) and the alternating contraction of wrist flexors and extensors as antiphase (AP).

These effects were explored further in a second experiment with the addition of a secondary probe reaction time task to assess demands on central capacity, and the analysis of wrist flexor and extensor electromyographic activity. Subjects returned longer reaction times for AP than IP movement, suggesting the AP movement pattern placed a greater demand on central capacity than the IP movement pattern. During this kinesthetic tracking task, similar dynamic principles emerged as those observed during bilaterally active bimanual rhythmical coordination.

Subjects were seated with eyes closed on a servo-controlled linear sled. They were asked to relax and received brief accelerations either sideways or in the fore-aft direction. The stimuli had an abrupt onset, comparable to the jerk experienced during a minor car collision. Rotation and translation of the head and body were measured using an Optotrak system. In some of the subjects, surface electromyographic (EMG) responses of selected neck and/or back muscles were recorded simultaneously. For each subject, responses were highly stereotyped from the first trial, and showed little sign of habituation or sensitisation. Comparable results were obtained with sideways and fore-aft accelerations. During each impulse, the head lagged behind the trunk for several tens of milliseconds. The subjects' head movement responses were distributed as a continuum in between two extreme categories. The 'stiff' subjects showed little rotation or translation of the head relative to the trunk for the whole duration of the impulse. In contrast, the 'floppy' subjects showed a large roll or pitch of the head relative to the trunk in the direction opposite to the sled movement. This response appeared as an exaggerated 'inertial' response to the impulse. Surface EMG recordings showed that most of the stiff subjects were not contracting their superficial neck or back muscles. We think they relied on bilateral contractions of their deep, axial musculature to keep the head-neck ensemble in line with the trunk during the movement. About half of the floppy subjects displayed reflex activation of the neck muscles on the side opposite to the direction of acceleration, which occurred before or during the head movement and tended to exaggerate it. The other floppy subjects seemed to rely on only the passive biomechanical properties of their head-neck ensemble to compensate for the perturbation. In our study, proprioception was the sole source of sensory information as long as the head did not move. We therefore presume that the EMG responses and head movements we observed were mainly triggered by the activation of stretch receptors in the hips, trunk and/or neck. The visualisation of an imaginary reference in space during sideways impulses significantly reduced the head roll exhibited by floppy subjects. This suggests that the adoption by the central nervous system of an extrinsic, 'allocentric' frame of reference instead of an intrinsic, 'egocentric' one may be instrumental for the selection of the stiff strategy. The response of floppy subjects appeared to be maladaptive and likely to increase the risk of whiplash injury during motor vehicle accidents. Evolution of postural control may not have taken into account the implications of passive, high-acceleration perturbations affecting seated subjects.","url":"https://pubmed.ncbi.nlm.nih.gov/11313451/","authors":["Vibert N","MacDougall HG","de Waele C","Gilchrist DP","Burgess AM","Sidis A","Migliaccio A","Curthoys IS","Vidal PP"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2001 May 1","doi":"10.1111/j.1469-7793.2001.0851e.x","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:10752945","name":"Prospects for treating acquired pendular nystagmus with servo-controlled optics.","source":"pubmed","abstract":"To determine whether a device featuring electronically controlled motor-driven prisms can reduce oscillopsia and improve acuity in patients with acquired pendular nystagmus (APN).","url":"https://pubmed.ncbi.nlm.nih.gov/10752945/","authors":["Stahl JS","Lehmkuhle M","Wu K","Burke B","Saghafi D","Pesh-Imam S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2000 Apr","doi":"","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:11042480","name":"Control system for an implantable rotary blood pump.","source":"pubmed","abstract":"Rotary blood pumps can be used for long-term left ventricular assist devices. These pumps have several advantages over the conventional pulsatile pumps including smaller size, higher efficiency, and simple design and construction. However, one of the difficulties associated with the rotary blood pump is the proper control method to maintain an optimum flow rate in different physiological conditions. The rotary blood pump can be controlled by two methods. The first is to utilize the measured pump flow rate from its servo signal. The second is to detect and avoid abnormal pumping conditions such as; back flow and sudden increase in the pressure head. This abnormal situation typically occurs from excessive suction of blood when there is a functional or mechanical occlusion in the inflow cannula. The ultrasound flow meter is durable and reliable but it is difficult to continually monitor the blood flow rate of an implantable pump. Therefore, another method is needed instead of the continuous flow monitoring. One chronic calf having an LVAD was subjected for the development of this control system. This calf survived more than 6 months. Voltage, current, motor speed, heart rate and the pump flow rate were recorded and stored at 30-min intervals in a computer. Utilizing these parameters, attempts were made (1) to achieve indirect flow assessments and (2) to reveal abnormal operating parameters of the centrifugal pump (1). Indirect flow measurement, the predicted pump flow rate was calculated from these pump derived parameters (required power, motor speed and heart rate). The value of the coefficient of determination (R) between the measured and estimated pump flow rate was 0.796.

To test whether or not canal-otolith interaction in humans is similar to that in rhesus monkeys, we examined ten healthy human subjects on a three-axis servo-controlled motor-driven turntable. The subjects were oscillated in upright or supine position in complete darkness over a similarly wide range of frequencies (0.05-1.0 Hz) with peak velocities &lt;40 degrees/s. Eye movements were recorded using the three-dimensional search coil technique. Compared with the torsional vestibulo-ocular gains during canal-stimulation only (earth-vertical axis), the gains obtained during combined canal-otolith-stimulation (earth-horizontal axis) were significantly higher throughout the entire frequency range (P&lt;0.05). The gain increased by 0.100+/-0.074 (SD), independent of frequency. During the earth-horizontal axis stimulation, the phase remained always around zero, which is in contrast to the canal-stimulation only, during which one finds an increasing phase lead as frequency decreases. We conclude that, in healthy humans as in rhesus monkeys, the phase lead from the canal signals at low frequencies is effectively cancelled by the otolith input. In contrast to rhesus monkeys, however, otolith signals in healthy humans increase the gain of the torsional VOR at frequencies from 0.05 to 1.0 Hz.

This stimulus evoked small but consistent postsynaptic potentials in every peroneal motoneuron. Weak stimuli elicited only excitatory postsynaptic potentials (EPSPs), whereas increase in stimulation strength allowed distinction of three patterns of response. In about one half of the sample, mechanical stimulation or trains of 20/s electric pulses at strengths up to six times the threshold of the most excitable fibers in the nerve evoked only EPSPs. Responses to electrical stimulation appeared with 3-7 ms central latencies, suggesting oligosynaptic pathways. In another, smaller fraction of the sample, inhibitory postsynaptic potentials (IPSPs) appeared with an increase of stimulation strength, and the last fraction showed a mixed pattern of excitation and inhibition. In 24 of 32 motoneurons where electrical and mechanical effects could be compared, the responses were similar, and in 6 others, they changed from pure excitation on mechanical stimulation to mixed on electrical stimulation. With both kinds of stimulation, stronger stimulations were required to evoke inhibitory postsynaptic potentials (IPSPs), which appeared at longer central latencies than EPSPs, indicating longer interneuronal pathways. The similarity of responses to mechanical and electrical stimulation in a majority of peroneal motoneurons suggests that the effects of commonly used electrical stimulation are good predictors of the responses of peroneal motoneurons to natural skin stimulation.

Recordings have been made from multiple single muscle spindle afferents from medial gastrocnemius (MG) and tibialis anterior (TA) muscles of one hindlimb in decerebrate cats, together with ankle rotation and EMG signals, during treadmill locomotion. Whilst the other three limbs walked freely, the experimental limb was denervated except for the nerves to MG and TA and secured so that it could rotate only at the ankle joint, without any external load. Each afferent was characterised by succinylcholine testing with regard to its intrafusal fibre contacts. Active movements were recorded and then replayed through a servo mechanism to reproduce the muscle length changes passively after using a barbiturate to suppress gamma-motor firing. 2. The difference in secondary afferent firing obtained by subtracting the discharge during passive movements from that during active movements was taken to represent the profile of static fusimotor activity. This indicated an increase before the onset of movement followed by a strongly modulated discharge in parallel with muscle shortening during locomotion. The pattern of static firing matched the pattern of unloaded muscle shortening very closely in the case of TA and with some phase advance in the case of MG. The same effects were observed in primary afferents. 3. Primary afferents with bag1 (b1) contacts in addition showed higher firing frequencies during muscle lengthening in active than in passive movements. This indicated increased dynamic fusimotor firing during active locomotion. There was no evidence as to whether this fluctuated during the movement cycles. 4. When the mean active minus passive difference profile of firing in bag2-chain (b2c) type primary afferents was subtracted from that for b1b2c afferents, the difference was dominated by a peak centred on the moment of maximum lengthening velocity (v). 5. The component of the active minus passive difference firing due to b1 fibre contacts could be modelled by f(t) = av (where a is a constant) during lengthening and by f(t) = 0.2 av during shortening. The remainder of the difference signal matched the predictions of the static fusimotor signal derived from secondary afferents. 6. The findings are discussed in relation to the concept that the modulated static fusimotor pattern may represent a 'temporal template' of the expected movement, though the relationship of the results to locomotion in the intact animal will require further investigation. The analysis of the data indicates that the combined action of muscle length changes and static and dynamic fusimotor activity to determine primary afferent firing can be understood in terms of the interaction between the b1 and b2c impulse initiation sites.","url":"https://pubmed.ncbi.nlm.nih.gov/10713974/","authors":["Taylor A","Durbaba R","Ellaway PH","Rawlinson S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2000 Feb 1","doi":"10.1111/j.1469-7793.2000.t01-3-00515.x","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:10638439","name":"Distance estimation in the visual and visuomotor systems.","source":"pubmed","abstract":"Previous work has demonstrated that monocular vision affects the kinematics of skilled visually guided reaching movements in humans. In these experiments, prior to movement onset, subjects appeared to be underestimating the distance of objects (and as a consequence, their size) under monocular viewing relative to their reaches made under binocular control. The present series of experiments was conducted to assess whether this underestimation was a consequence of a purely visual distance underestimation under monocular viewing or whether it was due to some implicit inaccuracy in calibrating the reach by a visuomotor system normally under binocular control. In a purely perceptual task, a group of subjects made similar explicit distance estimations of the objects used in the prehension task under monocular and binocular viewing conditions, with no time constraints. A second group of subjects made these explicit distance estimations with only 500-ms views of the objects. No differences were found between monocular and binocular viewing in either of these explicit distance-estimation tasks. The limited-views subjects also performed a visually guided reaching task under monocular and binocular conditions and showed the previously demonstrated monocular underestimation (in that their monocular grasping movements showed lower peak velocities and smaller grip apertures). A distance underestimation of 4.1 cm in the monocular condition was computed by taking the y intercepts of the monocular and binocular peak velocity functions and dividing them by a common slope that minimised the sum of squares error. This distance underestimation was then used to predict the corresponding underestimation of size that should have been observed in the monocular reaches--a value closely approximating the observed value of 0.61 cm. Taken together, these results suggest that the monocular underestimation in the prehension task is not a consequence of a purely perceptual bias but rather it is visuomotor in nature--a monocular input to a system that normally calibrates motor output on the basis of binocular vision.","url":"https://pubmed.ncbi.nlm.nih.gov/10638439/","authors":["Servos P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2000 Jan","doi":"10.1007/s002210050004","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:10612560","name":"Biomimetic myoelectric hand with voluntary control of finger angle and compliance.","source":"pubmed","abstract":"The purpose of this study was to develop a new type of myoelectrically controlled biomimetic prosthetic hand which has almost the same dynamics as that of the neuromuscular control system of the finger muscles, and in mechanical properties of the muscles and of the stretch reflex.

Back pain is known to change motor patterns of the trunk. The purpose of this study was to examine the motor output of the erector spinae (ES) muscles during pain in the lumbar region. First, their voluntary activation was assessed during flexion and re-extension of the trunk. Second, effects of cutaneous and muscle pain on the ES stretch reflex were measured, since increased stretch reflex gain has been suggested to underlie increased muscle tone in painful muscles. 2. The trunk movement and electromyographical (EMG) signals from the right and left ES during pain were compared with values before pain. Controlled muscle pain was induced by infusion of 5 % saline into the right lumbar ES. Cutaneous pain was elicited by mechanical or electrical stimulation of the dorsal lumbar skin. The stretch reflex was evoked by rapidly indenting the right lumbar ES with a servo-motor prodder. 3. The results from the voluntary task show that muscle pain decreased the modulation depth of ES EMG activity. This pattern was associated with a decreased range and velocity of motion of the painful body segment, which would normally serve to avoid further injury. Interestingly, when subjects overcame this guarding tendency and made exactly the same movements during pain as before pain, the EMG modulation depth was still reduced. The results seem to reconcile the controversy of previous studies, in which both hyper- and hypoactivity of back muscles in pain have been reported. 4. In the tapped muscle, the EMG response consisted of two peaks (latency 19.3 +/- 2.1 and 44.6 +/- 2.5 ms, respectively) followed by a trough. On the contralateral side the first response was a trough (26.2 +/- 3.2 ms) while the second (46.4 +/- 4.3 ms) was a peak, similar to the second peak on the tapped side. Cutaneous pain had no effect on the short-latency response but significantly increased the second response on the tapped side. Surprisingly, deep muscle pain had no effect on the stretch reflex. A short-latency reciprocal inhibition exists between the right and left human ES. 5.

Anatomical evidence points to a multiplicity of closed sensorimotor loops, while electrophysiological data delineate the flow of electrical signals in these pathways. These loops process sensory input from the vibrissae and send projections to direct vibrissa movement, starting at the level of the hindbrain and proceeding toward loops that involve multiple structures in the forebrain. The nature of the vibrissa-related electrical signals in behaving animals has been studied extensively at the level of neocortical loops. Two types of spike signal are observed that serve as a reference of vibrissa motion: a fast signal that correlates with the relative phase of the vibrissae within a whisk cycle and a slow signal that correlates with the amplitude, and possibly the set-point, of the vibrissae during a whisk. Both signals are observed in vibrissa primary sensory (S1) cortex, and in some cases they are sufficiently robust to allow vibrissa position to be accurately estimated from the spike train of a single neuron. Unlike the case for S1 cortex, only the slow signal has been observed in vibrissa primary motor (M1) cortex. The control capabilities of M1 cortex were estimated from experiments with anesthetized animals in which progressive areas along the vibrissa motor branch were microstimulated with rhythmically applied currents. The motion of the vibrissae followed stimulation of M1 cortex only for rates that were well below the frequency of rhythmic whisking; in contrast, the vibrissae followed stimulation of the facial nucleus, whose cells directly drive the vibrissae, for rates above that of whisking. In toto, the evidence implies that there is fast signaling from the facial nucleus, through the mystacial pad and the vibrissae and up through sensory cortex, but only slow signaling at the level of the motor cortex and down through the superior colliculus to the facial nucleus. The transformation from fast sensory signals to slow motor control is an unresolved issue. On the other hand, there is a candidate scheme to understand how the fast reference of vibrissa motion in the whisk cycle may be used to decode the angle of the vibrissae upon their contact with an object. We discuss a circuit in which servo mechanisms are used to determine the angle of contact relative to the preferred phase of the fast reference signals. Support for this scheme comes from results with anesthetized animals on the frequency and phase entrainment of intrinsic neuronal oscillators in S1 cortex. A prediction based on this scheme is that the output from a decoder circuit is maximal when the angle of contact differs from the preferred phase of a fast regerence signal. In contrast, for correlation-based schemes the output is maximal when the angle of contact equals the preferred phase.","url":"https://pubmed.ncbi.nlm.nih.gov/10449057/","authors":["Kleinfeld D","Berg RW","O'Connor SM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1999","doi":"10.1080/08990229970528","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:10391596","name":"Robotic assistance of an active upper limb exercise in neurologically impaired patients.","source":"pubmed","abstract":"The principle of using robotic techniques to assist an active upper limb exercise is demonstrated in ten patients with weakness and spasticity.

In the decerebrate state, these heterogenic reflexes are either excitatory and length dependent or inhibitory and force dependent. Mechanographic analysis was used to obtain additional evidence that the muscle spindle primary ending and the Golgi tendon organ provide the major contributions to these reflexes, respectively. The tendons of the triceps surae muscles were separated and connected to independent force transducers and servo-controlled torque motors in unanesthetized, decerebrate cats. The muscles were activated as a group using crossed-extension reflexes. Electrical stimulation of the caudal cutaneous sural nerve was used to provide a particularly strong activation of MG and decouple the forces of the triceps surae muscles. During either form of activation, the muscles were stretched either individually or in various combinations to determine the strength and characteristics of autogenic and heterogenic feedback. The corresponding force responses, including both active and passive components, were measured during the changing background tension. During activation of the entire group, the excitatory, heterogenic feedback linking the three muscles was found to be strongest onto LG and weakest onto MG, in agreement with previous results concerning the strengths of heteronymous Ia excitatory postsynaptic potentials among the triceps surae muscles. The inhibition, which is known to affect only the soleus muscle, was dependent on active contractile force and was detected essentially as rapidly as length dependent excitation. The inhibition outlasted the excitation and was blocked by intravenous strychnine.

The original model applies four-point bending to right tibiae via an open-loop, stepper-motor-driven spring linkage. Depending on the magnitude of applied load, the model produces new bone formation at periosteal (Ps) or endocortical surfaces (Ec.S). Due to the spring linkage, however, the range of frequencies at which loads can be applied is limited. The modified system replaces this design with an electromagnetic vibrator. A load transducer in series with the loading points allows calibration, the loaders' position to be adjusted, and cyclic loading completed under load control as a closed servo-loop. Two experiments were conducted to validate the modified system: (1) a strain gauge was applied to the lateral surface of the right tibia of 5 adult female rats and strains measured at applied loads from 10 to 60 N; and (2) the bone formation response was determined in 28 adult female Sprague-Dawley rats. Loading was applied as a haversine wave with a frequency of 2 Hz for 18 sec, every second day for 10 days. Peak bending loads were applied at 33, 40, 52, and 64 N, and a sham-loading group was included at 64 N. Strains in the tibiae were linear between 10 and 60 N, and the average peak strain at the Ps.S at 60 N was 2664 +/- 250 microstrain, consistent with the results of Turner's group. Lamellar bone formation was stimulated at the Ec.S by applied bending, but not by sham loading. Bending strains above a loading threshold of 40 N increased Ec lamellar bone formation rate, bone forming surface, and mineral apposition rate with a dose response similar to that reported by Turner et al.

We conclude that the modified loading system offers precision for applied loads of between 0 and 70 N, versatility in the selection of loading rates up to 20 Hz, and a reproducible bone formation response in the rat tibia.

The grip force (normal to the contact surfaces) and the load force (tangential to the surfaces) were measured, along with the trajectory of the hand. The manipulandum was attached to two servo-controlled linear motors used to create inertial and viscous loads as well as a composite load, including inertial, viscous, and elastic components. The form of the hand trajectory was independent of load for some subjects but varied systematically across load conditions in others. Nevertheless, under all load conditions and in all subjects, grip force was modulated in parallel with, and thus anticipated, fluctuations in load force despite the marked variation in the form of the load function. This indicates that the CNS is able to predict the load force and the kinematics of hand movement on which the load depends.

Short-term simulation of static gamma-axons evoked a post-stimulation increase in the spindle ending firing, which can be recorded under both isometric and isotonic conditions on applying a weak extrafusal stimulation or without it. The movement-dependent after-effects were tested with a double-trapezoid pattern of muscle length (or load) changes. The after-effects consisted of the difference of firing rates at the same values of muscle length (or load) with opposite direction of movement to the steady states; these uncertainties were also present during constant stimulation of static gamma-axons. The rate difference showed a tendency to a certain decrease with stimulation rate increment. For diapason of the stimulation rates up to 125 impulses/s a small negative correlation (r = -0.61) between the firing rate differences and the gamma-stimulation rate has been registered in the population of primary endings tested under length servo-control conditions. Using a frequency-modulated intrafusal stimulation, a clockwise hysteresis dependence of the spindle firing rate upon stimulation rate was demonstrated.

Each unit was studied with stimuli delivered at multiple velocities from 0.5 to 32 cm/sec in at least two opposing directions.

The fast adapting mechanoreceptors exhibited higher sensitivity to stimulus velocity than the slowly adapting mechanoreceptors. The mean velocity at which the fast adapting units were predicted to first respond to movement was also higher.

To determine whether CSN stimulation-evoked LTF is a general property of spinal inspiratory motoneurones, phrenic and inspiratory internal intercostal (IIC) nerve activities were recorded in nine cats (eight anaesthetized; one decerebrate), which were vagotomized, paralysed, thoracotomized and ventilated with O2; airway CO2 was controlled by means of of a servo-respirator. Baseline conditions were established by setting the arterial CO2 pressure (Pa,CO2) at approximately 2 mmHg above the threshold for IIC activity. One CSN was stimulated (3 times threshold, 25 Hz, 0.5 ms duration) with five (2 min) trains, each separated by 5 min. 2. The peak integrated phrenic activity was elevated by 33% whereas IIC activity was elevated by 226% above baseline, 90 min post-stimulation (P &lt; 0.05). The results were similar when expressed as a percentage of the maximal neural activities (elicited by combined hypercapnia and CSN stimulation), although differences between the nerves were less pronounced. The burst frequency was not change following stimulation. 3. In five additional cats that were pretreated with the serotonin receptor antagonist, methysergide maleate (0.5-1 mg kg-1, I.V.), the CO2 thresholds of the phrenic (12 mmHg) and IIC nerves (22 mmHg) were increased (P &lt; 0.05), and LTF could not be elicited in either neurogram. 4. Successive CSN stimulation episodes evoked a previously undescribed phenomenon. Although the peak integrated phrenic activity was unchanged (90-95% of maximal), IIC activity increased progressively during successive stimulus episodes (66-90% of maximal; P &lt; 0.05). However, after methysergide treatment, the initial stimulus-evoked phrenic response decreased to 58% of maximal and both neurograms exhibited progressive augmentation of the stimulus-evoked response. As stimulus-evoked augmentation does not require serotonin, it is independent of LTF. 5. We conclude that CSN stimulation-evoked LTF of IIC activity exceeds that of phrenic activity. Since LTF requires the neuromodulator serotonin and is expressed predominantly by changes in burst pattern formation versus rhythm generation, serotonin may exert a greater influence on IIC relative to phrenic respiratory motor output. A unique mechanism is described whereby successive CSN stimulus episodes cause progressively increasing responses in both neurograms.","url":"https://pubmed.ncbi.nlm.nih.gov/7932235/","authors":["Fregosi RF","Mitchell GS"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1994 Jun 15","doi":"10.1113/jphysiol.1994.sp020208","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:7954082","name":"Catching a ball: contributions of intrinsic muscle stiffness, reflexes, and higher order responses.","source":"pubmed","abstract":"In three sets of experiments in nine normal subjects and a patient with a percutaneous wrist-stabilizing splint, we quantified the open-loop gain (OLG) of the stretch reflex acting about the elbow. The subjects exerted a steady mean flexing force and were instructed not to intervene (i.e., not to resist actively) when force or displacement perturbations were imposed on the forearm. The method was either to reconstruct transmission around the entire loop in a two-part experiment, or to use the attenuation of external perturbations in normal and electrically stimulated muscle to compute gain. Across all experiments, the mean magnitude of stretch reflex OLG was close to unity in the frequency range 1-2 Hz, and declined at higher frequencies, as required to ensure stability, given that the phase lag approached 180 degrees at 5 Hz. Inherent muscle stiffness was approximately equal to reflex stiffness. In functional terms, an OLG of 1 means that the yield caused by a force perturbation is approximately halved by reflex action (prevailing inherent muscle stiffness is doubled). Automatic scaling of reflex transmission at Ia/alpha-motoneuronal synapses ensures that the OLG remains close to unity as inherent stiffness increases. Trials in the patient with the wrist fixator gave similar results, indicating that the reflexes were proprioceptive ly mediated. In a fourth experiment in which the task was to catch a heavy ball, we compared the efficacy of inherent muscle stiffness and reflexes alone, with the subject's intentional reactions, which included predictive and voluntary components of response. The latter were far more effective in maintaining the position of the hand after the ball was caught than inherent and reflex stiffnesses alone. We conclude that stability requirements limit the extent to which stretch reflexes can augment inherent muscle stiffness. When inherent muscle stiffness is low, such as in our ball-catching task, the reflex stiffness is also low, and predictive and pre-programmed reactions predominate in load compensation, thus shifting the emphasis from automatic servo or equilibrium-point behaviour to higher order control.","url":"https://pubmed.ncbi.nlm.nih.gov/7954082/","authors":["Bennett DJ","Gorassini M","Prochazka A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1994 May","doi":"10.1139/y94-076","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:8012828","name":"Late electromyographic activity following stretch in human forearm muscles: physiological role.","source":"pubmed","abstract":"We have previously found that the late reflex electromyographic (EMG) responses to muscle stretch are simultaneously present in both the stretched muscle and its antagonist, suggesting that it may be involved in the control of limb stiffness rather than in a servo-mechanism that returns the limb to an initial or intended position. Nevertheless, in these earlier experiments the size of the late EMG activity was always greater in the stretched muscle than its antagonist, suggesting also a possible servo-role for these responses. To clarify this, we have now recorded the late EMG activity simultaneously from both the right extensor and flexor carpi radialis muscles in ten subjects under four experimental conditions. These conditions differed in which muscle was activated voluntarily prior to the stretch stimulus and in which muscle was stretched by the perturbing force. In all cases subjects were asked to maintain the limb in a fixed position and oppose any displacement that occurred. The amount of integrated EMG activity for both the M2 and M3 components of the late response was greater in the agonist muscle (i.e., the muscle actually stretched by the perturbing force) than the antagonist. The ratio of agonist to antagonist activity, however, was significantly larger for the M2 than for the M3 component. These results suggest that both the M2 and M3 components of the late EMG response have a dual functional role, being involved both in a servo-mechanism and in the control of limb stiffness.

The main problem is that the latencies inherent in the transmission of physiological signals cause a delayed feedback of sensory information. Therefore, the muscle command signals cannot be explained by a simple servo-loop, so a more sophisticated control structure is required. Our hypothesis is that the CNS employs an internal representation of the controlled system in order to circumvent the drawbacks of the physiological loop delay. To test this hypothesis a mathematical model based on an internal representation and an internal state feedback has been developed. Computer simulations of double-step stimuli (control behaviour), tendon vibration and torque disturbances (disturbance behaviour) and load perturbations (adaptation behaviour) proved to agree remarkably well with experimental observations. The proposed control model can explain the open-loop and closed-loop aspects of human motor control.

Four speakers addressed a large audience on the proposition that \"one can only control what one senses.\" Charles Vierck supported the notion with a description of the severe motor deficits caused by lesions of the spinal dorsal columns (DCs) in monkeys. In the discussion of Vierck's presentation, Robert Forget described the difficulties experienced by deafferented patients in tasks of daily life. Next, John Brooke showed that sensorimotor transformations vary greatly with task, anticipation, and uncertainty. In light of this, he questioned the simplifications inherent in servo and equilibrium-point theories of motor control. Paul Cordo then showed that in a rapid throwing task, proprioceptive information is used to control the moment of release (contradicting the idea that sensory feedback is too delayed for ballistic movements). Dick Burgess, like Brooke, criticized equilibrium-point models; he argued that a subject's sense of effort is a measure of the internal motor command, which should correspond to specific equilibrium points. However, his experimental data were inconsistent with this interpretation. He suggested instead that motor output is adjusted by comparing incoming afferent information to an expected \"afferent template.\" Anatol Feldman and Mark Latash disagreed, saying that a constant sense of effort does not imply a constant equilibrium-point command. The equilibrium-point debate was not resolved, but the symposium ended with a consensus that in most motor tasks, one can control only what one senses.","url":"https://pubmed.ncbi.nlm.nih.gov/8017146/","authors":["McCloskey DI","Prochazka A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1994","doi":"10.3109/08990229409028859","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"pmid:7948639","name":"Four axial structural and material test machine.","source":"pubmed","abstract":"Structural tests of complex motion segments, such as those found in numerous joints in the body, require a flexible test bed capable of coordinated multiple axis control and a thorough understanding of the forces and moments.

The human data support the theory of alpha-gamma coactivation. In particular, in the early phase of isometric voluntary contractions fusimotor-driven afferent spindle activity assists in autogenetic activation of alpha motoneurons and in reciprocal relaxation of antagonists. As muscle fatigue develops, the autogenetic reflex drive via the fusimotor route declines. The fusimotor bias during contraction provides for maintenance of spindle sensitivity to minute perturbations and for load-compensating reflex adjustments to such perturbations.

During each condition the viscosity of the motor was held constant by a computer while subjects tracked, by moving their forearm in the sagittal plane, a visually presented target whose position changed randomly every 1.5 s for 255 s. Nonparametric and parametric impulse response functions were calculated between the input (target) and output (position) in each tracking condition. Nonparametric analyses revealed that subjects became sluggish at higher viscosities (above 200 N.s/m) and took longer to reach the target. A second-order low-pass transfer function was found to provide a very good description of tracking performance at each viscous level. The gain and damping parameter of this transfer function were not affected by the manipulandum's viscosity, whereas both the pure delay and natural frequency of the human operator system decreased systematically with increasing manipulandum viscosity.

Prior studies of this phenomenon have established that mechanical events of the previous beat influence the function of the current beat, but it is not known whether the important mechanical influence is exerted by previous beat ejection or previous beat pressure. In addition, the magnitude of the effect of previous beat contraction history on left ventricular performance is unknown. To make these determinations, we performed experiments in six isolated rabbit left ventricle preparations buffer perfused at 30 degrees C. Left ventricular pressure and volume were controlled precisely with a servo-controlled linear motor system. After steady-state ejecting conditions were established by clamping left ventricular ejection pressure at 60% of peak isovolumic pressure, single test beats, which were pressure clamped at 40%, 60%, 80%, and 100% of peak isovolumic pressure, were introduced and followed by an isovolumic reference beat. As the level of pressure clamp decreased from 100% to 40%, developed pressure on the isovolumic beat following the single test beats increased from 139 +/- 15 (mean +/- SD) to 151 +/- 13 mm Hg. Similarly, peak positive left ventricular dP/dt increased from 1,718 +/- 209 to 1,864 +/- 181 mm Hg.sec-1 (both p less than 0.01). Multiple regression analysis showed that this increase in left ventricular function was related to previous beat ejection but not to previous beat pressure load or relaxation.(ABSTRACT TRUNCATED AT 250 WORDS)","url":"https://pubmed.ncbi.nlm.nih.gov/1934333/","authors":["Slinker BK","Shroff SG","Kirkpatrick RD","Campbell KB"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1991 Oct","doi":"10.1161/01.res.69.4.1051","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"doi:10.5281/zenodo.21947869","name":"Design and Development of a Low-Cost Automated Toll Gate System Using Arduino Uno and Ultrasonic Sensing","source":"datacite","abstract":"Abstract: Reducing fuel usage, improving transportation efficiency, and decreasing road congestion all depend on effective toll collection.

Conventional multirotors generate roll and pitch torque from thrust differential (strong) but produce yaw torque only from motor reaction drag (weak); yaw is universally the limiting axis. The system described here uses gimballed, spinning rings to produce precession torque on all three body axes, with a coordinated bias-angle strategy that converts the otherwise-uncontrollable yaw direction into a fully actuated one. I derive the ring precession torque from first principles using the *true* finite-angle angular velocity of the tilted gimbal frame, prove that the resulting body torque is exactly the negative time-derivative of ring angular momentum (i.e. the gyros transfer momentum rather than create free torque), and validate this against zero-input conservation tests to numerical tolerance. I add physically credible actuator limits (servo speed–torque curves, thermal derating, gear backlash, bearing drag, and ring spin dynamics), CAD-grade full inertia tensors with uncertainty bands, a reachable-torque-envelope analysis, a 500-trial Monte Carlo robustness study, a controller-baseline comparison, and an ablation study of an experimental Fractal Correction Engine (FCE) predictive layer. On the identical 1.95 kg airframe, the gyroscopic system delivers approximately **6× the yaw torque** and a far more balanced yaw-to-roll authority ratio (1 : 3.7 versus 1 : 7.1) compared with a conventional quadcopter, and roughly **20× better impulsive-gust disturbance rejection**. A discovered hover roll limit-cycle, caused by a standing ring bias, is eliminated by demand-gating the bias, reducing hover roll RMS from 12.5° to 0.00° while fully retaining on-demand yaw authority. The FCE is shown to provide no genuine look-ahead advantage over a simple velocity predictor; its closed-loop benefit is an incidental proportional-feedback effect, and it is therefore retained only as an experimental, ungated feedforward layer. --- ## 1. Introduction Multirotor aircraft are now ubiquitous, but their control authority is fundamentally asymmetric. Roll and pitch torques arise from differential thrust across a moment arm and are strong; yaw torque arises only from the aerodynamic reaction (drag) torque of the propellers and is an order of magnitude weaker. This makes yaw the limiting axis for disturbance rejection, agile heading changes, and stability in wind. A control-moment gyroscope (CMG) stores angular momentum in a spinning rotor and produces torque by reorienting (gimballing) that rotor: `τ = ω_g × H`. CMGs are the workhorse of spacecraft attitude control precisely because they produce large, fast torques without expending propellant. This work asks whether a compact CMG array — three concentric counter-rotating rings on two-axis gimbals — can be embedded in a quadrotor airframe to give it strong, balanced three-axis authority, especially in yaw.

Unlike conventional control moment gyroscope (CMG) designs that suffer from gimbal lock singularities and weak yaw authority, our system exploits the nonlinear coupling between counter-rotating ring pairs at finite tilt angles to achieve near-uniform torque authority across all three body axes. A configuration-dependent Jacobian allocator with adaptive bias angle management replaces the traditional constant allocation matrix, yielding a **55x improvement in yaw torque** ($0.034$ to $1.864$ N$\\cdot$m) while preserving 96.6% of roll/pitch authority --- all within existing $\\pm 15^{\\circ}$ servo limits and without hardware modification. The system integrates a Fractal Correction Engine (FCE) for trajectory prediction and feedforward control enhancement. Full 6-DOF simulation with quaternion-based RK4 integration at 500 Hz validates the design against hover stability, step response, yaw authority, wind gust rejection, and aggressive maneuver scenarios. The resulting system achieves angular rates of approximately $246^{\\circ}$/s in yaw and $300$--$400^{\\circ}$/s in roll/pitch, placing it in the performance class of commercial sport-mode quadcopters while maintaining the mechanical simplicity and vibration isolation benefits of gyroscopic attitude control. --- ## 1. Introduction Multirotor UAVs conventionally achieve attitude control through differential motor thrust. While effective, this approach couples attitude authority directly to propulsion system bandwidth and creates inherent tradeoffs between agility, efficiency, and vibration. Control Moment Gyroscopes (CMGs) offer an alternative: by redirecting the angular momentum of spinning flywheels through gimbal actuation, large control torques can be generated without varying motor speeds. CMG-based attitude control has been extensively studied in spacecraft applications, where single-gimbal and double-gimbal configurations provide high torque-to-mass ratios. However, adapting CMGs to small UAVs introduces unique challenges: 1. **Gimbal lock singularities** limit the effective workspace of conventional CMG arrays2. **Cross-coupling torques** between the spinning elements and body rotation require active cancellation3. **Yaw authority** in axially-symmetric ring configurations is inherently weak compared to roll and pitch This paper addresses all three challenges through a coordinated counter-rotating ring pair actuation strategy. The key insight is that counter-rotating rings tilted to opposite bias angles produce **additive** yaw torque through the nonlinear $\\sin(\\theta)$ terms in the precession equation, while their nominal roll/pitch contributions remain largely unaffected ($\\cos(\\theta) \\approx 0.97$ at $15^{\\circ}$). We further integrate a Fractal Correction Engine (FCE) --- a signal analysis framework using fractal geometry, pi-scaled autocorrelation, and wave interference decomposition --- to provide trajectory prediction and curvature-based feedforward control enhancement. ### 1.1 Contributions - Derivation and correction of the full nonlinear precession torque model for tilted counter-rotating rings- A coordinated ring pair allocation strategy with adaptive bias management that achieves 55x yaw torque improvement within existing actuator limits- Integration of fractal-geometric trajectory prediction into the flight control loop- Comprehensive 6-DOF simulation validation as a digital twin of a CNC-manufactured prototype --- ## 2.

It employs sensory receptors to report how much of the objective is accomplished and, in the light of this feedback, modifies the program of muscular contraction. (Note however that certain rapid movements may be \"learned\" so well by practice that feedback becomes unnecessary). In the muscle these sensory receptors (muscle spindles) lie in parallel with the muscle fibers and share their attachments, so that they are extended when the muscle lengthens and relaxed when it shortens. The signals (impulses) generated by stretching the spindles travel towards the spinal cord and excite the alpha motoneurons which in turn cause the contraction of the muscle fibers surrounding these same spindles. Therefore an externallyinduced extension of the muscle resulta in an augmented muscular contraction which resists the extension; this mechanism, known as the \"stretch-reflex\", has the properties of a servo-mechanism,i.e. a self-regulating closed-loop mechanism using feedback from the spindles to maintain a given muscle length.

Results from a first study indicate that direct contact between fingerpad and object is important during haptic exploration. This was hypothesized to be so since the stereotypical contact region that is defined between fingerpad and object during direct contact is fundamentally different from the contact region defined through interaction of the object with an intermediary such as a probe. In an attempt to artificially create local contact region deformation trajectories, a servo-controlled mechanism was designed to roll a flat plate on the fingerpad during exploration of virtual surfaces thereby mimicking trajectories that are normally observed during direct fingerpad exploration of a physical object. Using the mechanism, it was demonstrated that through the presentation of this single cue an experience of touching three-dimensional shapes could be created. The importance of additional cues, such as number of contact points and motor control effects, on the haptic acquisition of shape information were also investigated.","url":"https://doi.org/10.82308/25846","authors":["Dostmohamed, Hanifa"],"tags":["Electronics and Electrical Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2005","doi":"10.82308/25846","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"doi:10.82308/47659","name":"The effect of altering the head's mechanics on gaze shift accuracy in humans /","source":"datacite","abstract":"A novel methodology for investigating the performance of the eye-head coordination system in humans is proposed. The objective is to alter the head's mechanics by applying torque loads during gaze shifts. A servo-motor, connected to the subject's head through a \"motor shaft-to-dental bite\" arrangement, is applying brief torque pulses in order to both aid and resist the head's movement, thus increasing and reducing respectively the head's velocity. The subjects perform a simple visual task to guide their gaze shifts in the dark, that is, after fixating on a standard point in space, a briefly flashed target will indicate the amplitude of the required gaze movement. Three targets appear in the horizontal plane within, at the limits of, and beyond the human oculomotor range (40°, 55°, and 70° respectively) in order to cover a significant range within which the head's contribution to the gaze coordinated movement is indispensable. The main question, the proposed methodology aims to answer, regards the effect of the torque loads on gaze shift accuracy. Two (2) subjects were tested under the above-mentioned conditions. Their accuracy was not significantly affected, although both head velocity and gaze duration were considerably altered by the torque loads. The results support the existence of a feedback control mechanism in the eye-head coordination system that keeps track of the on-going movement and adjusts the movement's kinematics on-line accordingly.","url":"https://doi.org/10.82308/47659","authors":["Kokkinos, Vasileios."],"tags":["Neuroscience"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2006","doi":"10.82308/47659","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"doi:10.5281/zenodo.21691228","name":"Internet of Things Based Electronic Toll Gate  and Smoke Control System","source":"datacite","abstract":"In our regular day to day existence, explorers pay a guaranteed measure of assessment all the route through toll court to the administration.

Their application has only gained acceptance since the 1970’s with the advent of vector control, microprocessors and improvements in power converter technology. D.C. motors were traditionally the preferred choice in HPMD systems. The main reasons for IM acceptance in HPMD systems are ruggedness, durability, low maintenance, cost, and small size by comparison with D.C. motors. Alternating current asynchronous motors of the IM type are considered to be the universal workhorses of the manufacturing industry. It has been estimated that they are used in seventy to eighty per cent of all industrial drive applications, although the majority are in fixed speed applications such as pump or fan-drives. This thesis initially examines the relative advantages and disadvantages of the D.C. and IM motors. The main disadvantage of the asynchronous squirrel-cage IM is its control complexities in ASD applications and its non-linear operation, which can be overcome through low cost effective DSP solutions. In general, the control of IM’s in HPMD systems can be classified into two distinct categories. The first of these is a traditional approach and is referred to as scalar control. Scalar control represents a means of obtaining speed control, and in the squirrel-cage IM this is achieved using both variable voltage/fixed frequency and variable frequency/fixed voltage supplies. For one such application of scalar control the constant volts per hertz (V/f) scheme is examined. Although a scalar controlled IM drive provides good speed control it does not provide a precise torque control capability with flux stabilisation. This was ascertained through simulation exercises of a scalar controlled IM drive in this thesis. In order to achieve the performance required by servo applications, IM’s have to be controlled using vector controllers. The key features that differentiate between scalar and vector controllers are: • Vector Control is designed to operate with a standard a.c., squirrel-cage asynchronous IM of known characteristics. If the characteristics of the IM are not known precisely then the vector control scheme can become totally inoperative. In many cases a Kalman observer is used for IM parameter estimation. • A vector controller and its associated IM form an integrated drive; the drive controller and the motor have to be matched to achieve satisfactory performance. • The vector controlled IM supplied currents are controlled both in magnitude and phase in real-time, in response to the demand and to external disturbances. To examine the difficulties associated with the constant volts per hertz (V/f) scalar control technique a comprehensive study of the rotor flux-oriented vector control technique has been considered in this thesis.. Such a technique that relies heavily on the Parks transformation of the three-phase stator currents from the a-p stationary reference frame (s) to a special x-y reference frame for two-axis vector control is presented in this thesis. This transformation enables the asynchronous squirrel-cage IM to achieve a level of performance the same as that of a D.C. motor, in terms of precise torque control with flux stabilisation, but without the disadvantages associated with D.C. motor usage. Numerous IM drive simulations have been undertaken for a variety of load torque conditions to illustrate the essential differences between scalar and vector control. With precise torque control, high-performance applications such as industrial machine tools, spindle drives, and cutters can be implemented by employing a two- axis controlled IM drive. To implement the rotor flux-oriented control technique particular attention is drawn to the development of a high-performance space vector pulse-width modulated (SV-PWM) voltage source inverter (VSI)- fed IM drive in the Matlab/Simulink software environment, that incorporates ","url":"https://doi.org/10.34719/sxcr4338","authors":["Pat Cronin"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2003","doi":"10.34719/sxcr4338","addedAt":"2026-08-31T06:34:40.355Z","updatedAt":"2026-08-31T06:34:40.355Z"},{"id":"doi:10.1109/pesc.1994.373845","name":"High performance and high precision ultrasonic motor-actuated positioning servo drive system using improved fuzzy-reasoning controller","source":"crossref","abstract":"","url":"https://doi.org/10.1109/pesc.1994.373845","authors":["Y.

A finite element model was built to analyze the dynamic response of the stator. The influence of the structural parameters on the dynamic performances, i.e., sensitivity parameters, was calculated to analyze the stability of the structure. Based on these analytical works, a prototype of the stator was developed and mode testing was conducted. The experimental results showed that the proposed design was able to achieve respectable performance: Despite the dual-mode design, the frequency difference between the two working modes was minimized to 608 Hz; and the prototype could operate stably under 55.4 kHz, providing a 0.5 N load with 980 mm/s speed.","url":"https://doi.org/10.3390/act9040111","authors":["Yin Wang","Ziyan Chen","Yunlai Shi","Changcai Cui","Fang Cheng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-11-05T09:04:34Z","doi":"10.3390/act9040111","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.1049/cp:19941025","name":"New speed tracking controlled direct-drive servo system using compact travelling-wave type ultrasonic motor","source":"crossref","abstract":"","url":"https://doi.org/10.1049/cp:19941025","authors":["Y.

In the control system development phase, direct testing on hardware is often at risk of mechanical damage due to programming errors or current surges. This study aims to conduct an in-depth analysis of the response characteristics of servo motors through a digital simulation approach as a preventive and validative step. The research method applied was a software-based laboratory experiment using the Proteus 8 Professional with an Arduino Uno microcontroller as the central control unit. The main focus of this test lies in the evaluation of the accuracy of the motor angular movement against the pulse width modulation (PWM) provided through the Servo standard library. Data is collected through Virtual Terminal observations and position indicators on virtual servo components. The results show that the Proteus simulation is able to represent the dynamics of angular motion linearly with a 100% accuracy rate to theoretically entered work cycle parameters. The study concludes that the use of virtual modeling is not only effective in minimizing the risk of physical failure.","url":"https://doi.org/10.70610/jcpa.1240","authors":["Fathul Ulum","Muhamad Nur Alvyangga Saputro","Mokhammad Syafaat","Kasiyanto"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-11T14:34:51Z","doi":"10.70610/jcpa.1240","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.5207/jieie.2006.20.6.096","name":"An Adoptive Current Control Scheme of an AC Servo Motor for Performance Improvement of a Servo Drive","source":"crossref","abstract":"","url":"https://doi.org/10.5207/jieie.2006.20.6.096","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-06-14T00:38:02Z","doi":"10.5207/jieie.2006.20.6.096","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.1115/imece2009-11027","name":"The Green, Digital Clamping Device Composed of Self-Locking Power Screw Driven by the Servo Motor","source":"crossref","abstract":"Fluid transmission, such as hydraulic and pneumatic, is widely used in the fixtures in modern industry. But there are some disadvantages in these fixtures. First, too much loops and turns in the hydraulic or pneumatic systems have lead to lower energy utilization ratio and complicated structure. Second, oil emission in hydraulic system may cause environment pollution, and the noise in pneumatic system may cause pollution too. Third, fluid system always needs electro-hydraulic or electro-pneumatic transform elements for digital intelligent control, which will add the cost and the complexity of system. In order to overcome this disadvantage, a new kind of mechatronics clamping device is designed innovatively, which is driven by servo motor and translated along the self-locking power screw. So it was very simple with little transmission elements and has no high-speed mechanic components. By changing the geometry shape of basic link, different requirements for clamping forces and clamping situations can be satisfied. This new kind of clamping device has prominent advantages in green and digital aspects. Moreover, it can meet perfectly the requirements of short-cycle, high-volume production in modern manufacturing industry.","url":"https://doi.org/10.1115/imece2009-11027","authors":["Yang Liu","Kangmin Zhong","Xiaoming Sheng","Mingdi Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-07-07T22:13:41Z","doi":"10.1115/imece2009-11027","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.32531/jelekn.v6i2.226","name":"ARM ROBOT PEMINDAH BARANG (AtwoR) MENGGUNAKAN MOTOR SERVO MG995  SEBAGAI PENGGERAK ARM BERBASIS ARDUINO","source":"crossref","abstract":"Perkembangan teknologi yang semakin canggih dan pertumbuhan industri yang semakin berkembang di Indonesia.

Compared with conventional proportional–integral control, deadbeat current control can considerably enhance the current control loop bandwidth. However, because the deadbeat current control performance is strongly affected by the variations in the electrical parameters, tuning the controller gains to achieve a satisfactory current response is crucial. Because of the prompt current response provided by the deadbeat controller, the gains must be tuned within a few control periods. Therefore, a fast online current loop tuning scheme is proposed in this paper. This scheme can accurately identify the controller gain in one current control period because the scheme is directly derived from the discrete-time motor model. Subsequently, the current loop is tuned by updating the deadbeat controller with the identified gains within eight current control periods or a speed control period. The experimental results prove that in the proposed scheme, the motor current can simultaneously have a critical-damped response equal to its reference in two current control periods. Furthermore, satisfactory current response is persistently guaranteed because of an accurate and short time delay required for the current loop tuning.","url":"https://doi.org/10.3390/en12183555","authors":["Zih-Cing You","Cheng-Hong Huang","Sheng-Ming Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-09-23T04:50:21Z","doi":"10.3390/en12183555","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1109/iicpe.2006.4685382","name":"DSP controlled soft switched push-pull ZCS_QRC Fed DC servo motor for aerospace applications","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iicpe.2006.4685382","authors":["M.

Sayangnya, kebiasaan membuang sampah seringkali terhambat karena rasa enggan menyentuh tutup tempat sampah yang dianggap kotor dan berpotensi menjadi sarang kuman atau virus. Penelitian ini hadir untuk menjawab tantangan tersebut melalui pengembangan 'Smart Trash Bin', sebuah tempat sampah otomatis tanpa sentuh yang menawarkan higienitas lebih baik. Secara teknis, sistem ini mengandalkan Arduino Uno sebagai otak utama, yang dipadukan dengan sensor ultrasonik HC-SR04 untuk mendeteksi objek, serta motor servo untuk menggerakkan tutupnya. Melalui pendekatan metode eksperimental pada hardware dan software, pengujian menunjukkan hasil yang memuaskan. Sensor mampu membaca keberadaan tangan atau sampah dalam rentang jarak 10 hingga 30 cm. Saat terdeteksi, sistem secara otomatis memerintahkan servo membuka tutup hingga 90 derajat dan akan menutup kembali setelah jeda 3 detik. Dengan tingkat keberhasilan respon mencapai 95%, alat ini sangat layak diterapkan sebagai solusi sanitasi modern, baik untuk rumah tangga maupun area publik.","url":"https://doi.org/10.64803/juikti.v2i1.107","authors":["Rio Rinaldi","Fayyaz Haqqani","Dhafa Hibrizi Sitorus"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-01-24T03:40:16Z","doi":"10.64803/juikti.v2i1.107","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:43.479Z"},{"id":"doi:10.1117/12.942966","name":"DC-Brushless Servo System Without Rotor Position And Speed Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1117/12.942966","authors":["Hiroshi Watanabe","Takashi Isii","Tomoo Fujii"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-10-02T20:22:29Z","doi":"10.1117/12.942966","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1117/12.942963","name":"Ac Synchronous Servo Based On The Armature Voltage Prediction Model","source":"crossref","abstract":"","url":"https://doi.org/10.1117/12.942963","authors":["Akihiro Hoshino","Hiroshi Kuromaru","Shinichi Kobayashi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-10-02T20:22:29Z","doi":"10.1117/12.942963","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.1109/ramech.2008.4690886","name":"A new algorithm research and simulation for permanent magnet synchronous motor ac servo system","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ramech.2008.4690886","authors":["Jingmeng Liu","Tianmiao Wang","Dong Xu","Linan Cong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-12-09T18:02:57Z","doi":"10.1109/ramech.2008.4690886","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.1541/ieejias.115.1186","name":"Two-dimensional Servo Control of Surface Motor.","source":"crossref","abstract":"","url":"https://doi.org/10.1541/ieejias.115.1186","authors":["Daiki Ebihara","Tomokatsu Takahashi","Masaya Watada"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-07-13T11:02:06Z","doi":"10.1541/ieejias.115.1186","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:44.659Z"},{"id":"doi:10.1109/rusautocon65989.2025.11177380","name":"Algorithm of Operation of the Digital Controller of the High-Speed Response Servo Drive with the Synchronous Motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/rusautocon65989.2025.11177380","authors":["Ilgiz Baybikov","Vladimir Kozlovskiy","Alexander Starikov"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-30T17:37:01Z","doi":"10.1109/rusautocon65989.2025.11177380","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:42.635Z"},{"id":"doi:10.1109/28.585861","name":"A fully digital control strategy for synchronous reluctance motor servo drives","source":"crossref","abstract":"","url":"https://doi.org/10.1109/28.585861","authors":["Y.Q.

Narrow tilting vehicles (NTV), known also as three–wheeled vehicles, can be equipped with an active tilting stability controller that tilts the vehicle automatically during cornering to enable lateral stability. There are mainly direct tilt control (DTC), steering tilt control (STC), and combined DTC–STC methods described in the literature. The DTC method is typically applied up to 10 km/h vehicle speeds. Considering city traffic and frequent start–stop cycles, the DTC method needs to be improved in terms of lower actuator torque and energy consumption. DTC can be designed by using either hydraulic or servo motor actuators. In state of the art, the servo motor actuator has not been studied in detail considering its integration and application aspects. Mostly, the actuator has been considered as a black box model. Proposed control method in this study enables improvements in the direct tilt control system (DTC) in terms of reducing the actuator peak torque and enables the application of DTC at higher vehicle speeds. Regarding the modeling of the electric actuator, a permanent magnet synchronous motor and field-oriented control model are also included in the simulation model. Modelling of the electric actuator enables accurate representation of actuator dynamics. In this way, battery Ah capacity can be sized and energy consumption of the electric actuator can be calculated for a given drive cycle. To this end, objective of this study is to design a direct tilt control method including the electrical drives and motion control concepts. In this way, an application methodology of the servo motor actuator is developed and implemented on a narrow tilting three-wheeled electric vehicle. Interactions between tilt control system and the servo motor actuator system are described from practical aspects.","url":"https://doi.org/10.3390/en15061996","authors":["Mustafa Karamuk","Orhan Behic Alankus"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-03-09T11:30:38Z","doi":"10.3390/en15061996","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1109/icems59686.2023.10344667","name":"An Improved Second-Order Linear Active Disturbance-Rejection Control for Permanent Magnet Synchronous Motor Servo System","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icems59686.2023.10344667","authors":["Weiye Cai","Haozhe Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-12-14T19:22:21Z","doi":"10.1109/icems59686.2023.10344667","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1063/1.4875029","name":"Damping properties for vibration suppression in electrohydraulic servo-valve torque motor using magnetic fluid","source":"crossref","abstract":"Aiming to suppress high frequency vibrations of a torque motor in electrohydraulic servo-valves, damping properties of an ester-based Fe3O4 magnetic fluid operating in the squeeze mode are studied in this Letter.

Mechanical misalignments and temperature fluctuations are some of the environmental reasons that commonly cause resolvers to suffer from problems in calibration. The contribution of this work is to present a methodology for the calibration of 16-bit resolvers using 14 different Machine Learning (ML) techniques that improve the accuracy and reliability of LEO ground stations. Conventional calibration techniques include mechanical adjustment of the resolver for known inaccuracies. This often involves much manual refinement and recalibration to achieve any reasonable degree of accuracy. On the other hand, the proposed automatic calibration would reduce the need to routinely perform human calibration, thereby reducing wastage of time and other resources. Machine Learning statistical algorithms can learn from data and generalize to new data, including complex input-output mappings, and have made such error profiles and resolution features visible. This software-based error-compensation technique improved the target distortion ratio of a 16-bit resolver from approximately ±10% to approximately ±2%. In cases where ML is used for calibration, it is possible to reduce the goal angle error—which can reach up to 1°—to a level of 0.2°.Cite this article as: Y. Sancar and R.

Permanent magnet synchronous motor driven constant pump hydraulic system is designed instead of common motor, energy saving, fast response and easy to realize closed loop control. System uses the structure of the combination of neural network control and RBF network online identification. The parameters of the controller are optimized by PSO algorithm offline and error back propagation (BP) algorithm offline, and a RBF network is built to identify the system online. The hydraulic power system’s control simulation experiments are conducted, and the experimental results at the typical working conditions of the hydraulic source show that the controller and its optimization algorithm can effectively improve the system performance, and the system has no steady-state error, good dynamic performance and good robustness, superior to conventional fuzzy controller and PID controller.","url":"https://doi.org/10.21307/ijssis-2017-812","authors":["Ma Yu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-11-23T05:44:01Z","doi":"10.21307/ijssis-2017-812","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.3850/978-981-08-7723-1_p183","name":"System Identification for AC Servo Motor and Dynamometer using ARX Model and NNARX Model","source":"crossref","abstract":"","url":"https://doi.org/10.3850/978-981-08-7723-1_p183","authors":["Sarun Umpavan","Seelawat Chankaew","Waree Kongprawechnon","Teera Phatrapornnant"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-01-04T19:55:29Z","doi":"10.3850/978-981-08-7723-1_p183","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1109/asc-icsc.2008.4675447","name":"Modeling and simulation of ultrasonic motor driving jet-pipe servo valve system","source":"crossref","abstract":"","url":"https://doi.org/10.1109/asc-icsc.2008.4675447","authors":["Nie Lingcong","Yao Xiaoxian","Li Qing"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2008-11-25T10:48:47Z","doi":"10.1109/asc-icsc.2008.4675447","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1109/emeit.2011.6023374","name":"Research on the key technique of continuous rotary electro-hydraulic servo motor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/emeit.2011.6023374","authors":["Xiaojing Wang","Jianying Li","Junpeng Shao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-10-12T16:24:52Z","doi":"10.1109/emeit.2011.6023374","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.1109/tencon.2011.6129192","name":"FPGA based DC servo motor control for remote replication of movements of a surgical arm","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tencon.2011.6129192","authors":["Vivek Ramakrishnan","Nalamwar Sanchit Gopal","Rahul Ashok","S.

Without the speed sensor, the extended Luenberger observer is implemented to estimate the rotor speed of the DC motor in the presence of the disturbance torque. With this knowledge of the speed estimated from the observer, the servo state‐feedback controller can drive such a rotor speed to follow the desired one. The stability and performance of the DC drive system can be guaranteed by the optimal control which minimizes the H 2 norm of the closed‐loop feedback control and observer system. The simulation and experiment studies are demonstrated for the effectiveness of the proposed control methodology in a practical approach for the sensorless DC drive.

As DC Motors are commonly used in many industrial applications and robotics, studies in this paper have are tested on a DC servo system, which is designed and produced by Quanser Inc. Three different types of sliding mode controllers are designed for position control of servo system and, later, performance comparison of DC Motor on Servo system is made. According to results obtained from real-time servo system, it is shown that SMC method is robust against to disturbing effects, variabilities, and uncertainties on the systems. Outstanding part of this paper is that designed controllers are implemented to servo system in real-time with a variable loaded DC Motor.

Some issues concerning with the design and control of flapping wing mechanism are discussed in this paper. Firstly the problem of phase-lag between two wings is treated. To eliminate phase-lag, a method of modifying the design is proposed. Then, motion controlling of a flapping wing mechanism by means of changing the voltage inputted to servo motor is studied. Based on Lagrange’s formulation and Kirchhoff’s voltage law, motion equation for a servo motor coupled to flapping wing mechanism is established. Fourth-order Runge-Kutta method is employed to integrate this equation. For the purpose of finding the relationship between the flapping motion and the input voltage, a response diagram obtained from simulation of the system is utilized. A crucial voltage VC is obvious in the response diagram. If the input voltage is lower than VC, the mechanism will settle at its fixed point, only when the input voltage is higher than VC, can the mechanism work in order. Both to find all fixed points and to analyze their stability for a complex nonlinear dynamic system are difficult tasks. A numerical method to deal with these difficulties is proposed. The results of simulation also show that the flapping frequency increases with the increasing of input voltage provided that the input voltage is higher than VC.","url":"https://doi.org/10.1115/detc2010-28555","authors":["Jin Xie","Yong Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-03-23T19:31:25Z","doi":"10.1115/detc2010-28555","addedAt":"2026-08-31T06:34:41.842Z","updatedAt":"2026-08-31T06:34:41.842Z"},{"id":"doi:10.3390/a11100152","name":"Accelerated Iterative Learning Control of Speed Ripple Suppression for a Seeker Servo Motor","source":"crossref","abstract":"To suppress the speed ripple of a permanent magnet synchronous motor in a seeker servo system, we propose an accelerated iterative learning control with an adjustable learning interval.

The pumping rate is electronically controlled to maintain a constant pressure within the windkessel max. 700 mmHg. The maximal flow rate is 300 ml/min. To reduce the high pressure in the windkessel to the desired coronary perfusion pressure, a variable flow resistance, comprising a clamped thin-walled silicone tube, is provided in the output line of the system. A fast servo-motor drives the clamp and is controlled by an electronic regulator, using a second feedback loop from the pressure signal measured at the tip of the perfusion cannula. The system stabilizes the coronary perfusion pressure within 300 ms. An additional modulation of the setpoint signal in synchrony with the cardiac cycle improves the phasic pattern of the blood flow, and thus prevents changes in transmural blood flow distribution.

We have shown in the isolated ventricular septum that, during steady-state indentations, the transverse stiffness (the ratio of indentation stress [pressure acting on indenter face] to indentation strain [amount of indentation/nonindented thickness]) can be used as an estimate of the in-plane wall stress. Because of the long acquisition time for those transverse stiffness determinations, it was not possible to follow changes in wall stress over a single contraction. We recently developed a dynamic indentation system that can determine transverse stiffness in as little as 10 ms, allowing estimation of wall stress over a single contraction cycle. The apparatus consists of an indentation probe coupled to a linear motor. This indentation system was tested on two beating canine ventricular septa that were mounted in a biaxial system the could apply strains in the plane of the septa and measure the resulting in-plane stresses. The probe indented the septa with peak displacements of 0.1-0.5 mm at frequencies of 20 and 50 Hz. The transverse stiffness was calculated as the slope of the relation between the indentation stress and indentation strain during each high-frequency indentation. Consistent with earlier studies, the transverse stiffness was related to the inplane stress. In contrast to earlier studies, however, these dynamic transverse stiffness determinations could be made during a single contraction. Thus, dynamic transverse stiffness determinations allow estimation of wall stress in the isolated septa by minimal surface contact, and may lead to methods for estimating wall stress in the intact heart.","url":"https://pubmed.ncbi.nlm.nih.gov/1879850/","authors":["Halperin HR","Tsitlik JE","Gelfand M","Downs J","Yin FC"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1991 Jun","doi":"10.1109/10.81586","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:2061838","name":"Vestibular and cerebellar modulation of expiratory motor activities in the cat.","source":"pubmed","abstract":"1.

The hypothesis was based upon the observation that spinal neural activities during expiration are greatly altered subsequent to a change in posture. 2. In decerebrate and paralysed cats, efferent activities were recorded from the central cut ends of the phrenic nerve, intercostal nerve, branch of the intercostal nerve innervating the triangularis sterni, cranial iliohypogastric (abdominal) nerve and recurrent laryngeal nerve. 3. Animals were artificially ventilated. Those with intact vagi were ventilated by a servo-respirator which produced changes in lung volume in parallel with alterations in integrated activity of the phrenic nerve. Animals with bilateral vagotomy were ventilated with a standard respirator. 4. Aspiration of the entire cerebellar cortex did not produce alterations in levels of neural activities; the respiratory frequency was increased modestly. Following ablation of the ventrolateral portion of corpus medullare and cerebellar peduncles, expiratory activities of spinal nerves were completely eliminated whereas inspiratory activities were not greatly altered. Results were similar in animals having either intact or sectioned vagi. 5. Electrical stimulation or chemical stimulation by glutamate of regions of the ventrolateral cerebellum produced little change in respiratory neural activities except when these stimulations were within the infracerebellar nucleus. Stimulations in this nucleus caused pronounced increases in expiratory activities of spinal nerves. Neither inspiratory activities of spinal nerves nor inspiratory or expiratory activities of the recurrent laryngeal nerve were altered. Studies in animals having intact or sectioned vagi yielded similar results. 6. Bilateral lesions of neurons in the infracerebellar nucleus by injections of kainic acid in animals having intact or sectioned vagi caused an irreversible loss of expiratory activities of spinal nerves with neither inspiratory spinal activities nor inspiratory and expiratory laryngeal activities being altered. Similar findings were obtained following unilateral ablation of the infracerebellar nucleus in vagotomized cats.

In the companion paper the gain of the stretch reflex in the ankle extensor muscles of normal cats was shown to increase after decerebration. The objectives of this study were 1) to identify the origin of the increased reflex and 2) to evaluate the contribution from afferents other than ankle extensor muscle afferents to the short-latency reflex. 2. Six cats were trained to stand unaided on four pedestals. Three cats were also trained to control the force exerted with the left hindlimb. The left soleus (SOL) and lateral gastrocnemius (LG) electromyogram (EMG), length, force, and temperature were recorded by chronically implanted electrodes and transducers. Measurements were taken before and after decerebration at the premammillary level. After decerebration limb temperature was returned to its normal range by the use of radiant heat. 3. Reproducible ramp-and-hold stretches and releases of the ankle extensor muscles were produced by a servo-controlled motor that rotated the left rear pedestal about the ankle joint. The length of the ankle extensor muscles changed by 2-3 mm within 30-35 ms after the onset of a ramp perturbation. Reflex responses before and after decerebration were compared at matched background values of muscle length and force. 4. In both the SOL and LG muscles, a short-latency EMG burst appeared 8-12 ms after stretch onset and lasted approximately 20 ms. After decerebration the onset of the rectified and smoothed EMG burst remained unchanged, but its area was increased by 36-89%. 5. The lateral gastrocnemius-soleus (LG-S) electroneurogram (ENG) was chronically recorded in two cats with a nerve cuff recording electrode implanted on the LG-S nerve. LG-S ENG activity started to increase soon after stretch onset and remained high during the entire ramp phase. The stretch-evoked LG-S ENG burst started approximately 8 ms earlier than the short-latency SOL and LG EMG bursts. It was interpreted to reflect mainly an increase in the activity of Group Ia and Ib muscle afferents, caused by increases in both muscle length and muscle force during the stretch. After the cats were decerebrated, for matched postural conditions, the area of the stretch-evoked LG-S ENG burst was increased by 29-35%. Because the length and force changes sensed by the muscle receptors before and after decerebration were similar, this suggests that the sensitivity of muscle spindles was increased as a consequence of altered activity in fusimotor neurons after decerebration.(ABSTRACT TRUNCATED AT 400 WORDS)","url":"https://pubmed.ncbi.nlm.nih.gov/2283544/","authors":["Sinkjaer T","Hoffer JA"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1990 Nov","doi":"10.1152/jn.1990.64.5.1625","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:2127466","name":"Influence of phasic volume feedback on abdominal expiratory nerve activity.","source":"pubmed","abstract":"Our purpose was to examine the influence of phasic lung volume feedback on the activities of motor nerves innervating the diaphragm and transversus abdominis muscles during hypercapnia and hypoxia.

The effects of phasic lung volume feedback were assessed by withholding pulmonary inflation during the central inspiratory period. Withholding lung inflation for a single respiratory cycle under hyperoxic, normocapnic conditions consistently prolonged the durations of the inspiratory and expiratory periods, and caused marked increases in the peak electrical activities of both phrenic and abdominal nerves. Hyperoxic hypercapnia (PaCO2 50-80 mmHg) and isocapnic hypoxia (PaO2 60-35 mmHg) increased peak phrenic and abdominal neural activities, and withholding pulmonary inflation under these conditions caused even greater augmentations of inspiratory and expiratory motor output. The augmentation of expiratory activity by withholding lung inflation was proportionately greater than the concomitant prolongation of the central expiratory period. All responses to non-inflation maneuvers were abolished following bilateral cervical vagotomy.

Distributed stimulation of ventral root filaments, rate-modulated by the step-cycle EMG envelope, served to reproduce step-cycle forces. The filaments were selected so as to have no fusimotor action on the test spindle. 4. Spindle responses in active cycles were compared with those in passive cycles (stretch, but no distributed stimulation). In some cases concomitant tonic fusimotor stimulation was used to maintain spindle responsiveness throughout the cycle, both in active and passive trials. Generally, small discrepancies in spindle firing were seen. The passive trials were now repeated, with iterative adjustments of the length function, until the response matched the spindle firing profile in the active trial. The spindle 'saw' the same internal length change in the final passive trial as in the active trial. Any difference between the corresponding length profiles was attributed to extramysial displacement. 5. Extramysial displacement estimated in this was was maximal at short mean muscle lengths, reaching about 0.5 mm in a typical step cycle (force rising from 0 to 10 N). At longer mean muscle lengths where muscle force rose from say 2 to 12 N in the cycle, extramysial displacement was in the range 0.2-0.4 mm. 6. Except at very short lengths, the displacement was probably mainly tendinous. On this assumption, our results suggested that the stiffness of the MG tendinous compartment was force related, and about double that of cat soleus muscle at any given force. Calculations indicated that though the stretch was small, the MG tendon would store and release enough strain energy per cycle to contribute significantly to the E3 phase of the step cycle. The discrepancies in spindle firing were generally quite subtle, so we reject the claim that extramysial stretch poses a serious difficulty for inferences about fusimotion from chronic spindle afferent recordings.","url":"https://pubmed.ncbi.nlm.nih.gov/2148952/","authors":["Elek J","Prochazka A","Hulliger M","Vincent S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1990 Oct","doi":"10.1113/jphysiol.1990.sp018254","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:2207742","name":"Generating precise mechanical stimuli and recording chordotonal organ discharge patterns using a microcomputer.","source":"pubmed","abstract":"A computer-controlled system for the investigation of the response properties of the tibio-femoral chordotonal organ in the locust is described.

Target distance was 8 or 16 cm, randomly chosen. To exert a force in the direction of the movement subjects had to activate flexors of both shoulder and elbow, but shoulder flexors did not change appreciably in length during the movement. In 20% of the trials the inertial load was increased or decreased without knowledge of the subjects. Until 90-110 ms after the onset of the agonist muscle activity (about 65-85 ms after the start of movement) EMG activity was very similar in all conditions tested. The changes that occurred in the EMG from that moment on were effectively a later cessation of the agonist activity and a later start of the antagonist activity if the load was increased unexpectedly. If the load was reduced unexpectedly, the agonist activity ceased earlier and the antagonist activity began earlier. The latency at which EMGs started to change was the same for muscles around shoulder and elbow, for agonists and antagonists and for both distances. All adjustments had the same latency (37 ms) relative to the point where the angular velocity of the elbow in the unexpectedly loaded movements differed by 0.6 rad/s from the expected value. We discuss why simple reflex- or servo-mechanisms cannot account for the measured EMG changes.

A successful trial consisted of maintaining the force applied on the left rear pedestal within the target window for a preset time period. To assist the cat, a light was turned on whenever the force was within the target window. A food pellet reward was delivered by the computer after each successful trial.

Within 1 min after induction of stenosis heart rate and end-diastolic left ventricular pressure (plved) increased (by 20 and 60%, respectively) and mean aortic pressure and dplv/dtmax decreased (by 10 and 25%, respectively). After the initial decrease median myocardial blood flow further decreased between 1 and 5 min of stenosis from 0.63 to 0.32 ml.min-1.g-1 in the outer layers (P less than 0.05) and from 0.26 to 0.15 ml.min-1.g-1 in the inner layers (P less than 0.05), despite constant hemodynamic conditions and pcor.

Secondary spindle afferents and the FRA: a new hypothesis.","source":"pubmed","abstract":"A hypothesis is forwarded regarding the role of secondary spindle afferents and the FRA (flexor reflex afferents) in motor control. The hypothesis is based on evidence (cf. Lundberg et al. 1987a, b) summarized in 9 introductory paragraphs. Group II excitation. It is postulated that subsets of excitatory group II interneurones (transmitting disynaptic group II excitation to motoneurones) may be used by the brain to mediate motor commands. It is assumed that the brain selects subsets of interneurones with convergence of secondary afferents from muscles whose activity is required for the movement. During movements depending on coactivation of static gamma-motoneurones impulses in secondary afferents may servo-control transmission to alpha-motoneurones at an interneuronal level. The large group II unitary EPSPs in interneurones are taken to indicate that, given an adequate interneuronal excitability, impulses in single secondary afferents may fire the interneurone and produce EPSPs in motoneurones; interneuronal transmission would then be equivalent to that in a monosynaptic pathway but with impulses from different muscles combining into one line. It is postulated that impulses in the FRA are evoked by the active movements and that the role of the multisensory convergence from the FRA onto the group II interneurones is to provide the high background excitability which allows the secondary spindle afferents to operate as outlined above. The working hypothesis is put forward that a movement governed by the excitatory group II interneurones is initiated by descending activation of these interneurones, but is maintained in a later phase by the combined effect of FRA activity evoked by the movement and by spindle secondaries activated by descending activation of static gamma-motoneurones. As in the original \"follow up length servo\" hypothesis (Rossi 1927; Merton 1953), we assume that a movement at least in a certain phase can be governed from the brain solely or mainly via static gamma-motoneurones. However, our hypothesis implies that the excitatory group II reflex connexions have a strength which does not allow transmission to motoneurones at rest and that the increase in the gain of transmission during an active movement is supplied by the movement itself. Group II inhibition. It is suggested that the inhibitory reflex pathways like the excitatory ones have subsets of interneurones with limited group II convergence. When higher centres utilize a subset of excitatory group II interneurones to evoke a given movement, there may mobilize inhibitory subsets to inhibit muscles not required in the movement.(ABSTRACT TRUNCATED AT 400 WORDS)","url":"https://pubmed.ncbi.nlm.nih.gov/3556458/","authors":["Lundberg A","Malmgren K","Schomburg ED"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1987","doi":"10.1007/BF00236301","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:3478015","name":"The force-velocity relation of the rabbit digastric muscle.","source":"pubmed","abstract":"In 30 animals, the digastric was made to pull actively against a slide loaded by a servo-controlled linear motor.

The empirical force-velocity data were fitted to a hyperbolic equation. The average speed of muscle shortening at zero load was 14.67 cm/s.

Maximum muscle force was positively correlated with animal size, but maximum velocity showed no relation to force or length. The estimated maximum speed of sarcomere shortening was 26 micron/s, which is slightly slower than in fast limb muscles of the cat, and may indicate the presence of both histochemical type I and II fibres. The isometric force after shortening had ceased was less than P0, and was correlated with the velocity during shortening. This depression of isometric force may result from an alteration of the excitation-coupling system during activation.

A rotary valve between the pump and the cuirass varies the rate of extraction of air from the cuirass. The pressure within the cuirass is sensed by a pressure transducer, and the output of this is used to control the position of the rotary valve by means of a motor so that the pressure within the cuirass follows a predetermined half sine wave pattern. The respiratory rate varies from 10 to 30 per minute and the inspiratory to expiratory time (I/E) ratio from 3:2 to 2:3. Inspiratory pressure varies from 0 to -50 cm H2O and an expiratory pressure of 0 to +50 cm H2O can be imposed. The performance of the new pump was assessed in 21 patients with nocturnal hypoxaemia who were accustomed to external negative pressure ventilation.

We propose that the dependency of the relationship between reflex magnitude and imposed movement parameters on tonic motoneuron activity, as represented by pre-existing EMG levels, may reflect an automatic adjustment mechanism that could be utilized in servo compensation of movements requiring markedly different force levels.","url":"https://pubmed.ncbi.nlm.nih.gov/6733609/","authors":["Bedingham W","Tatton WG"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1984 May","doi":"10.1017/s0317167100045534","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6611405","name":"The dependence of force and shortening velocity on substrate concentration in skinned muscle fibres from Rana temporaria.","source":"pubmed","abstract":"The force-velocity relation was determined in fully activated skinned fibres from frog muscle at concentrations of the substrate, magnesium adenosine triphosphate (MgATP), ranging from 10 microM to 10 mM. The ionic strength of the solutions was 200 mM, temperature 0-5 degrees C, pH 7.1. The activation procedure of Moisescu (1976) was used to raise the calcium concentration rapidly in the interior of the fibres. A re-phosphorylating system (creatine kinase and creatine phosphate) was used to maintain the MgATP concentration in the fibres. Isotonic releases were performed using a fast servo-controlled motor and tension transducer. Releases to a pre-determined tension level relative to the isometric tension were made using a novel normalizing circuit. In some of the experiments changes of sarcomere length were recorded using the diffraction device described in the preceding paper (Goldman &amp; Simmons, 1984). There was satisfactory agreement between velocities determined from the total length change and the sarcomere length change. The isometric tension showed a biphasic dependence on MgATP concentration. Tension increased with MgATP concentration from 1 microM to reach a peak at about 30-100 microM and decreased by about 20% from the value at the peak with further increase in the MgATP concentration to 5 mM (about the physiological concentration). At 5 mM-MgATP, the isometric tension was approximately the same as in intact fibres, if allowance is made for the increase in cross-sectional area that occurs when the surface membrane is removed. The maximum velocity of shortening, Vmax, was obtained by fitting the force-velocity relation using Hill's (1938) equation. Vmax showed a roughly hyperbolic dependence on MgATP concentration, with a Km of 0.47 mM. At 5 mM-MgATP, the value of Vmax was 2.16 muscle lengths per second, which is similar to that of intact fibres. a/P0, the parameter of Hill's (1938) equation that is related to the curvature of the force-velocity relation, showed a slight decrease with increasing MgATP concentration. Its value at 5 mM-MgATP of 0.16 is somewhat lower than found for intact fibres. The results are discussed in terms of a simple model based on the biochemical cycle of hydrolysis of ATP by actomyosin in solution. The decrease of tension from about 30 microM to higher concentrations of MgATP can be related to the dissociating effect of MgATP on actomyosin. The increase of isometric tension from 1 to 30 microM-MgATP is discussed in terms of two types of rigor attachment of cross-bridges which support different amounts of tension.(ABSTRACT TRUNCATED AT 400 WORDS)","url":"https://pubmed.ncbi.nlm.nih.gov/6611405/","authors":["Ferenczi MA","Goldman YE","Simmons RM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1984 May","doi":"10.1113/jphysiol.1984.sp015216","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6741639","name":"Diagnosis of cavernous haemangiomas by computed tomography and angiography.","source":"pubmed","abstract":"Computed tomography and angiographical findings of cavernous haemangiomas of the brain are reported on the basis of six cases of the authors, and a review of the literature.

Our purpose was to develop a versatile myographic system appropriate for the in vitro study of 75-250 micron diameter vessels and to explore different physiological properties of cerebral and mesenteric arteries. In this paper the system is described in detail, examples of its use in determining the dynamic responses of the vessels to electrical stimulation are provided, and certain measures indicative of the extent of myogenic behavior are characterized. Cylindrical artery segments about 3-mm long were dissected from Wistar-Kyoto rats and mounted in a chamber filled with physiological saline solution maintained at 37 degrees C. The same solution was perfused via a syringe into one end of the vessel through a microcannula. The other end was then occluded so that experiments could be made over a wide range of transmural pressures without flow. The vessel was viewed through a microscope coupled with a TV camera, and the video output signal of a selected scan line was processed by an electronic dimension analyzing system. This permitted simultaneous digital presentation and analog voltage outputs of the vessel wall thicknesses and lumen diameter. We further incorporated servo control of the syringe using a motor drive. In this way, vessel tests could be carried out at constant pressure or constant diameter, and vessel responses could be obtained following either pressure or diameter command signals. Using the methods presented in this study, small vessels can be maintained under conditions that approximate their in vivo state more closely than other in vitro techniques using ring segments on wires. We also find that the opto-electronic instrumentation is ideally suited for studying the dynamic vessel properties that underlie the control of vascular smooth muscle.","url":"https://pubmed.ncbi.nlm.nih.gov/6534218/","authors":["Halpern W","Osol G","Coy GS"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1984","doi":"10.1007/BF02363917","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6466804","name":"Integrity of arterial endothelium following acute exposure to high shear stress.","source":"pubmed","abstract":"Shear-induced injury or denudation of arterial endothelium has been implicated in atherogenesis.

Fusimotor and alpha-motor units in the masseter nerve were differentiated on the basis of their response to passive ramp and hold stretches applied to the jaw. Spindle afferents were identified as primary or secondary according to their dynamic index after administration of suxamethonium. The activity of a given fusimotor unit during reflex movements of the jaw followed one of two distinct patterns: so-called 'tonic' units showed a general increase in activity during a movement, without detailed relation to lengthening or shortening, while 'modulated' units displayed a striking modulation of their activity with shortening, and were usually silent during subsequent lengthening. Comparison of the simultaneously recorded fusimotor and spindle afferent activity suggests that modulated units may be representative of a population of static fusimotor neurones, and tonic units of a population of dynamic fusimotor neurones. In these lightly anaesthetized animals, both primary and secondary spindle afferents showed increased firing during muscle shortening as well as during lengthening. This increase during shortening is not usually seen in conscious animals and reasons are given for the view that it is due to greater depression of alpha-motor activity than of static fusimotor activity during anaesthesia. The results are discussed in relation to the theories of 'alpha-gamma co-activation' and of 'servo-assistance'; and it is suggested that static fusimotor neurones provide a 'temporal template' of the intended movement, while dynamic fusimotor neurones set the required dynamic sensitivity to deviations from the intended movement pattern.","url":"https://pubmed.ncbi.nlm.nih.gov/6229627/","authors":["Gottlieb S","Taylor A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1983 Dec","doi":"10.1113/jphysiol.1983.sp014986","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6875651","name":"Response to sudden torques about ankle in man: V effects of peripheral ischemia.","source":"pubmed","abstract":"Sudden dorsiflexions and plantar flexions of the foot were imposed by a torque motor while blood flow to the lower leg was occluded by a sphygmomanometer cuff. Seated subjects were instructed to resist the torques and restore the foot to its original position as rapidly as possible. Measurements of the first two electromyographic (EMG) responses were made in the soleus (SOL) and anterior tibial (TA) muscles. These are the myotatic reflex at about 40 ms and the postmyotatic response at about 120 ms. In the anterior tibial muscle, the myotatic component often occurs at 60- to 90-ms latency and is continuous with the postmyotatic component. After about 20 min of ischemia, there is a rapid and eventually complete loss of the myotatic component of the response in the stretched muscle. Concurrent with the loss of the myotatic reflex there is usually a reduction of the postmyotatic component. The latency of postmyotatic component remains unchanged, even after the myotatic reflex is abolished. Voluntary restoration of the foot to its original position in opposition to the motor torque is delayed and slowed by the time that the myotatic reflex has vanished. By measuring electromyographic responses to visually triggered reactions, we demonstrate that the reduction of the postmyotatic response is not due to failure of the efferent pathway. On this basis we discuss the possible contributions made by myotatic mechanisms to the tasks of load compensation and maintenance of muscle tone. Hoffmann reflexes were evoked in similar experiments with stimulation of the posterior tibial nerve at the popliteal fossa, distal to the cuff. The maximal direct motor response and muscle twitch are unaffected by loss of the H-reflex. Myotatic and Hoffmann reflexes were both evoked with torque perturbations and with a stimulating electrode proximal to a below-the-knee cuff. In this case, the myotatic reflex failed while the maximal H-reflex was slightly facilitated. The loss of the myotatic reflex was accompanied by a modest reduction in the direct motor response to electrical stimulation and a somewhat greater reduction in the postmyotatic response to torque perturbation. The data are interpreted to support a dual role for the primary afferent pathway in the control of voluntary movements. It provides the fastest path for the activation of a stretched muscle to initiate a load-compensating contraction. It also provides a form of servo assistance in modulating descending control signals. The degree of this assistance is estimated. In this simple experimental paradigm, functional contributions of the reflex arc are demonstrated.","url":"https://pubmed.ncbi.nlm.nih.gov/6875651/","authors":["Gottlieb GL","Agarwal GC","Jaeger RJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1983 Jul","doi":"10.1152/jn.1983.50.1.297","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6224051","name":"A new simulation method to deduce fusimotor activity from afferent discharge recorded in freely moving cats.","source":"pubmed","abstract":"Direct recordings from identified and classified fusimotor gamma-motoneurons in freely moving animals have not so far been achieved, and present knowledge on fusimotor activity during natural movements is based on qualitative inferences made from spindle afferent discharge.

The patients were classified clinically into four groups according to the degree of rigidity at the elbow or tremor. Stretch reflexes were evaluated while the subject was exerting a small force against a constant preload supplied by a torque motor, and the size of the reflex response was measured as fractional increase over basal levels of activity. When stretches were given at random intervals by increasing the force exerted by the motor by a factor of 2 or 3, there was a clear trend for the more severely affected patients to have larger long latency responses in the triceps muscle, although there was no change in the size of the short-latency, spinal component of the response. In contrast, there was no change in the size of the long-latency response of the flexor pollicis longus in any group of patients with Parkinson's disease. Despite any differences in reflex size, the inherent muscle stiffness of both muscles appeared to be normal in all groups of patients with Parkinson's disease, since the displacement trajectory of the limb following the force increase was the same as control values in the short (25 ms) period before reflex compensation could intervene. In 20 of the patients and in seven of the control subjects, servo-controlled, ramp positional disturbances were given to the thumb. Up to a velocity of 300&#xb0;/s, the size of the long-latency stretch reflex was proportional to the log velocity of stretch. This technique revealed, in both moderately and severely rigid patients, increases in the reflex sensitivity of the flexor pollicis longus, which had not been clear using step torque stretches alone. However, whether using ramp or step displacements, long latency stretch reflex gain was not closely related to rigidity; reflex size was within the normal range in many patients with severe rigidity. Enhanced long latency stretch reflexes thus contribute to, but may not be solely responsible for, rigidity in Parkinson's disease.","url":"https://pubmed.ncbi.nlm.nih.gov/6842198/","authors":["Rothwell JC","Obeso JA","Traub MM","Marsden CD"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1983 Jan","doi":"10.1136/jnnp.46.1.35","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6216336","name":"Effect of fusimotor stimulation on ia discharge during shortening of cat soleus muscle at different speeds.","source":"pubmed","abstract":"1. In barbiturate-anaesthetized cats, the L7 and S1 dorsal and ventral roots were dissected to isolate functionally single afferents identified as primary endings of soleus muscle spindles, and motor filaments which exerted a fusimotor action on the afferents with limited action on extrafusal muscle. Up to seven filaments, with an action on a given primary ending, could be isolated and each was classified as exerting either a predominantly dynamic or static action.2. Combined stimulation of these filaments, at rates up to 200 impulses/s could maintain afferent firing during muscle shortenings at speeds up to 200 mm/s.3. Fusimotor stimulation could also maintain afferent firing at a target frequency of 100 impulses/s during muscle shortenings up to 200 mm/s. The timing, in relation to the onset of shortening, and the rates of fusimotor stimulation were found to be critical in achieving the target frequency.4. Sinusoidal modulation of the frequency of fusimotor stimulation was used to study the conditions required to achieve constant afferent firing in the face of imposed sinusoidal length changes.5. For given depths of modulation, the phase advance of fusimotor stimulation needed to produce minimum modulation of afferent firing (best compensation) increased with increasing frequency of the sinusoids. The compensation deteriorated with an increase in the frequency of the sinusoids and a change in the mean muscle lengths, although in some cases it could be restored by adjustments to the depth of modulation of fusimotor rate. This suggests that for movements of varying speeds and amplitudes, settings which are appropriate for shortening at a given velocity and mean muscle length, do not apply if either of these two variables are altered.6. These findings demonstrate that the fusimotor system is potentially capable of eliciting constant afferent firing as envisaged in the ;servo-assistance' hypothesis (Matthews, 1964, 1972; Stein, 1974). This, and the fact that constant afferent firing is not seen during normal unobstructed shortenings at velocities greater than 0.2 resting length/s (Prochazka, 1981), are used to argue that it is by choice rather than necessity that ;servo-assistance' (as defined above) is not employed during normal movements.

After that, we instituted medical treatment for the afflicted workers and improvement of working conditions in the foundry, and have performed annual medical examinations for four years. In this paper, the course of hygienic control and the change in the medical findings of twenty-four chipping-hammer operators are reported. 1. The following measures were taken to improve the working conditions of chipping-hammer operators and therapy for patients (Table 1): (1) The operating time of vibrating tools, including chipping-hammer, was limited to two hours per day. The casting process was improved to diminish the flashes that are the objects of chipping-hammer operation. For the purpose of reducing the vibration transmitted to the operator, a servo-arm that has a servomechanism for the chipping-hammer was developed and introduced. (2) Infrared lamps in the foundry and air curtains at the doorway were installed for keeping the chipping-hammer operating area warm. A warm room was set up in the foundry for providing warmth during rest periods and protective clothing against the cold was provided. (3) Workers who displayed health disturbances by medical examinations were treated during the cold season from November to April by periodic visits to the clinic or extended hospitalization, or transferred to job without vibration exposure, according to their stage of disease. Preventive treatment with vasodilator and bubble bath was performed in winter for the chipping-hammer operators. 2. In order to estimate the effect of these countermeasures, annual medical examinations were conducted in March 1975, March 1976, April 1977 and March 1978. Such subjective symptoms as Raynaud's phenomenon, finger numbness, finger listlessness, heavy-headedness, forgetfulness, irritability and hearing disorder showed a tendency for improvement, but other complaints did not (Tables 2-4). The improvement of Raynaud's phenomenon is considered to be due not merely to the countermeasures but also to reducing the chance of provocation and therefore the countermeasures should not be overestimated as a factor of recovery of vibration hazards. Of the functional tests, a tendency for improvement was recognized in sensory functions and peripheral circulatory functions, but not in motor functions (Tables 5, 6). However, the course of recovery was not fast and some advanced cases, especially those using chipping-hammers for more than ten years, showed less improvement after hospital treatment (Table 7, Fig. 1). This indicates the importance of hygienic control which enables vibration hazards patients to have early diagnosis and treatment. Furthermore, in order to eradicate the vibration hazards in the cast metal industry, a drastic reform of the finishing process is considered to be necessary.","url":"https://pubmed.ncbi.nlm.nih.gov/7131885/","authors":["Harada N","Matsumoto T","Yamada S","Kobayashi F"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1982 Jan","doi":"10.1539/joh1959.24.75","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6224463","name":"[Characteristics of the innervation of various muscles in the ear, nose and throat area].","source":"pubmed","abstract":"This study shows different aspects of the innervation of some striated muscles.

Amongst the muscles of the external and middle ear, the soft palate and the larynx having opposite actions, there is in each case one muscle which does not have any spindles. These muscles then have only motor innervation. The muscles which have neuro-muscular spindles are innervated by nerves composed of extra- and intrafusal motor fibres and proprioceptive fibres. The neuro-muscular spindles play a servo-braking role in the muscle where they occur. The oppose then a certain passive elongation of the muscle. At the same time and in this manner, they contribute in controlling and restraining the action of the muscles or of their opponents. This role is particularly important for the various muscles of the oto-rhino-laryngological region and is all the more important since the amplitude of the movements which they cause is very weak.

Exteroceptive reflexes generate intense muscular responses and are of critical importance in prompt reprogramming essential for effective responses to environmental stimuli. Within the motor cortex (MI) there is a caudal region (MI/c) which receives exteroceptive cutaneous inputs and a rostral region (MI/r) which receives proprioceptive inputs. Transcortical reflexes mediated via pyramidal tract neurons (PTNs) of MI/r have properties which are analogous to segmental proprioceptive reflexes: changes of muscle length elicit PTN discharges which oppose the length change and so act to maintain stability. Furthermore, MI/r PTNs which are recruited earliest for small active movements are most sensitive to proprioceptive inputs. Data are not yet available concerning transcortical reflexes via MI/c during voluntary movement, but it is speculated that the cutaneous reflexes via MI/c might be functionally analogous to segmental cutaneous reflexes. Short-latency reflex responses also occur in postcentral (PoC) PTNs, and in this report we present results concerning the properties of PoC PTNs during active and passive movement. Caudal (area 2-5) PoC PTNs were similar to MI PTNs in that they often discharged prior to electromyogram (EMG) activity with active movement, and had different discharge frequencies with different steady state loads, but were unlike most MI PTNs in having the same changes of discharge with active and passive movement. Our finding of PoC discharge prior to movement onset, confirming that of Soso and Fetz in 1980, is discussed in connection with the concept of corollary discharge.","url":"https://pubmed.ncbi.nlm.nih.gov/6459153/","authors":["Evarts EV","Fromm C"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1981 Jul","doi":"10.1139/y81-112","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:6164534","name":"Comparison of monosynaptic tendon reflexes during preparation for ballistic or ramp movement.","source":"pubmed","abstract":"Mechanism which underlie preparation for movement were studied in man using the method of 'monosynaptic tendon reflexes' during the preparatory period (PP) preceding the execution of ramp or ballistic tracking movements. Reflex reactivity is more important during the whole of the PP to a ramp rather than a ballistic movement; the increasing facilitation preceding the execution signal is greater and occurs earlier for the ramp than for the ballistic movement. These results were observed for 'fast' or 'slow' subjects in a reaction time task, but were more marked for the latter. On the one hand, preparation for movement is represented at the spinal level by a competition between activating influences, which allows for the speeding up of peripheral execution of central control, and inhibitory influences brought into play both by the need to suppress the movement until the execution signal and by the isolation of motor structures from postural proprioceptive servo-mechanisms. On the other hand, this preparation can imply a control of the level of activity in proprioceptive fusorial afferent pathways which depends on whether the movement to be executed is open-loop (ballistic) or closed (ramp). Comparison between the results obtained from fast and slow subjects underlines the importance of an active inhibitory process in spinal structures which would accompany temporal adjustment.","url":"https://pubmed.ncbi.nlm.nih.gov/6164534/","authors":["Bonnet M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1981 Apr","doi":"10.1016/0013-4694(81)90099-7","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:7264986","name":"Spinal inhibition of phrenic motoneurones by stimulation of afferents from peripheral muscles.","source":"pubmed","abstract":"1.

In both groups, end-tidal PCO2 was maintained at a constant level by means of a servo-controller. 2. Physical stimulation of calf muscles in animals with intact central respiratory controller and a generally facilitatory effect on frequency, with appropriate changes of both inspiratory and expiratory durations, and on peak magnitude of phrenic (neural tidal) activity.

Physical stimulation of calf muscles or electrical stimulation of the tibial nerve in high spinal animals uniformly caused inhibition of spontaneous phrenic activity and that evoked by facilitatory conditioning stimuli. The degree of inhibition gradually decreased as muscle stimulation continued. Following offset of muscle stimulation, post-stimulus augmentation of phrenic activity occurred, with subsequent gradual return to control level over a period of 20-25 sec. 4.

Spectral analysis reveals that all frequencies of tremor show this increase. Maximal electrical stimulation of the motor nerve to the muscle does not result in any change in tremor so it is inferred that the increase is due to the operation of spinal or supra-spinal mechanisms. A sub-maximal voluntary effort, maintained for about 1 h, leads to the development of large amplitude, low frequency tremor (4-6 Hz) in addition to increased physiological tremor (8-12 Hz). It is generally accepted that physiological tremor originates as an oscillation in the reflex arc servo loop. The 4-6 Hz slow tremor of this type of fatigue also appears to arise as servo loop oscillation, the feedback delays being longer than in physiological tremor.

The longer-latency portions of the prolonged output have been variously reported to be servo-like or to be triggered in nature. In monkeys and humans, angular wrist displacements imposed by step loads result in three peaks (M1, M2 and M3) in the gross EMG recorded from the stretched muscles. Each gross EMG peak largely results from the firing of a separately-responding subpopulation of single motor units (SMUs). We studied the responses of SMUs to loads that were presented to the monkeys in a random order as to magnitude, duration and onset time. Average response histograms were constructed for the SMU responses for individual step load magnitudes. Averages were also constructed for the simultaneously-recorded gross EMG responses for each step load magnitude. The input parameters used were the initial velocity of displacement or the magnitude of step load, while the output was taken as the probability of firing/millisecond/presentation above baseline for the SMUs or the area under the response peaks above baseline for gross EMG. The results establish: 1) That it is not possible to unambiguously determine the input-output properties of the responses to imposed displacements utilizing the analysis of gress EMG activity due to the response characteristics of the various subpopulations of motor units contributing to the gross response. 2) That the SMU activity during all of the peak intervals is monotonically graded with increases in magnitude of the step load or the initial velocity of displacement. Hence, the long-latency portions of the EMG responses are servo-like in nature and are not preprogrammed or triggered responses. 3) That the gain (output/input) of the gross EMG responses almost entirely reflects the variation in the number of motoneurons recruited by changes in magnitude of the step loads rather than variation in the firing rates of motoneurons during the reflex responses.","url":"https://pubmed.ncbi.nlm.nih.gov/230067/","authors":["Tatton WG","Bawa P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1979","doi":"10.1007/BF00236816","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:362791","name":"Myoinositol and function of peripheral nerves in human diabetics.

Motor unit activity of the different muscles was recorded as electromyograms (EMGs). 1. Two types of proprioceptive reflex evoked by CB length changes have been investigated: (a) resistance reflexes of the two levator and two depressor muscles of the same leg segment, the coxopodite, i.e. 'intrasegmental reflexes', (b) 'intersegmental reflexes' induced in the muscles operating the proximal (T-C) joint of the same leg, and in all eight muscles of the limb segments distat to CB. 2. Both levator muscles respond reflexly to imposed CB stretch (which normally occurs with limb 'depression'), while both depressors respond during CB shortening (or passive \"elevation\" of the leg). 3. Intersegmentally CB stretch reflexly activates the M-C extensor muscle, and sometimes facilitates the T-C remotor and C-P bender muscles. Shortening of the single CB organ of a leg excites one or two tonic motor units of the T-C promotor and M-C flexor muscles, and also facilitates the remotor, I-M reductor, and the single stretcher-opener excitatory motoneurone. 4.

The servo-like properties of muscle in healthy human subjects have been studied by interfering unexpectedly with flexion movements of the top joint of the thumb. This movement is carried out by the flexor pollicis longus muscle only. 2. The movements were standardized in rate by giving the subject a tracking task. They started off against a constant torque load offered by an electric motor. 3. In some movements the load remained constant, but in others, in mid-course, perturbations were introduced at random. Either the movement was halted, or released and allowed to accelerate by reducing the load, or reversed by suddenly increasing the current in the motor, so stretching the muscle. 4. Usually eight or sixteen responses to each kind of perturbation and a similar number of controls against a constant load were averaged. 5. Muscle activity was recorded as the electromyogram from surface electrodes over the belly of the long flexor in the lower forearm. Action potentials were usually full-wave rectified and integrated. 6. About 50 msec after a perturbation the muscle's activity alters in such a sense as to tend to compensate for the perturbation, i.e. it increases after a halt or a stretch and decreases after a release. The latency is similar in each case. 7. These responses are interpreted as manifestations of automatic servo action based on the stretch reflex. They are considered to be too early to be voluntary. 8. This interpretation was supported by measuring voluntary reaction times to perturbations under tracking conditions. They were found to be 90 msec or longer. 9. When the initial load was increased by a factor of 10, the servo responses were all scaled up likewise. Thus to a first approximation the gain of the servo is proportional to initial load. 10. It follows that in relaxed muscle the gain should be zero. This was confirmed by showing that stretching a relaxed muscle gives no reflex, or only a small one. 11. Gain appears to be determined by the level of muscle activation as determined by the effort made by the subject, rather than by the actual pressure exerted by the thumb. 12. Thus in fatigued muscle gain is boosted as the muscle has to be activated more strongly to keep up the same force output. The net effect is to compensate for fatigue and maintain the performance of the servo. 13. The Discussion centres on the implications of gain control in the servo. For a start, if the gain of the stretch reflex arc is zero in relaxed muscle, contractions cannot be initiated via the stretch reflex by simply causing the spindles to contract, as proposed on the original 'follow-up' servo theory.","url":"https://pubmed.ncbi.nlm.nih.gov/133238/","authors":["Marsden CD","Merton PA","Morton HB"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1976 May","doi":"10.1113/jphysiol.1976.sp011354","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:1080798","name":"Variation of muscle stiffness with force at increasing speeds of shortening.","source":"pubmed","abstract":"Single frog skeletal muscle fibers were attached to a servo motor and force transducer by knotting the tendons to pieces of wire at the fiver insertions. Small amplitude, high frequency sinusoidal length changes were then applied during tetani while fibers contracted both isometrically and isotonically at various constant velocities. The amlitude of the resulting force oscillation provides a relative measure of muscle stiffness. It is shown from an analysis of the transient force responses observed after sudden changes in muscle length applied both at full and reduced overlap and during the rising phase of short tetani that these responses can be explained on the basis of varying numbers of cross bridges attached at the time of the length step. Therefore, the stiffness measured by the high frequency legth oscillation method is taken to be directly proportional to the number of cross bridges attached to thin filament sittes. It is found that muscle stiffness measured in this way falls with increasing shortening velocity, but not as rapidly as the force. The results suggest that at the maximum velocity of shortening, when the external force is zero, muscle stiffness is still substantial.

Overall muscle stiffness opposing load changes is determined by the visco-elastic properties of the muscle, by segmental reflex actions and finally by long-loop reflexes. Under certain circumstances, for instance when the subject or the experimental monkey is \"prepared\" to counteract perturbations which are unpredictable in time, the long-loop \"reflexes\" appear to be responsible for most of the corrective muscle tension. Experiments in anaesthetized monkeys revealed that signals from stretch afferents reach neurons of the motor cortex, possibly via a relay in the cortical area 3a. The latencies of these responses to well controlled muscle stretches were in the same range as motor cortical cell discharges recorded in alert monkeys subjected to load perturbations. Furthermore, these responses of cells in the motor cortex also had the appropriate timing to indicate a causal relationship with the long-latency electromyographic responses to load changes referred to above. These experimental results therefore strongly support the hypothesis, first proposed by Phillips (1969), of a transcortical servo-loop adjusting motor cortical output according to the load conditions in which movements are performed. The major advantage of transcortical regulations as opposed to segmental regulations, seems to be a powerful gain control acting at the cortical level; it was repeatedly shown that the long-loop reflexes are strongly modifiable and under voluntary control. It is suggested that an adaptive gain control at the cortical level is a prerequisite to preserve the complex capabilities of the motor cortex as the chief \"executive\" for skilled, preprogrammed movements. A loss of this adaptive gain control may be, at least partly, the cause of motor disorders such as rigidity in Parkinsonian patients, as reported by Tatton and Lee (1975). It is suggested that further investigations of the control of transcortical reflexes may aid in the understanding of the pathophysiology of motor disabilities.","url":"https://pubmed.ncbi.nlm.nih.gov/169980/","authors":["Wiesendanger M","Rüegg DG","Lucier GE"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1975 Aug","doi":"10.1017/s0317167100020394","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:150976","name":"Responses to load disturbances in human shoulder muscles: the hypothesis that one component is a pulse test information signal.","source":"pubmed","abstract":"Human motor control has been investigated by applying displacements acting to rotate the shoulder while the subject was endeavouring to maintain a constant position against a pre-existing force delivered by a system of finite stiffness. Four separate stages of the force response were distinguished. First, for the initial 100 msec, an increase in force which was attributed to the viscoelastic properties of activated muscle. Second, after approximately 100 msec, a \"medium latency\" increase in force accompanied by an increase in EMG activity. Third, a \"long latency\" increase in force consistent with voluntary action restored the arm to its original position. Fourth, some 500 msec thereafter and dependent upon the final steady force level, a tremor might develop. No changes of force were seen that were of sufficiently short latency to be attributed either to Ia monosynaptic action or immediately following (within 15 msec) polysynaptic action of muscle mechano-receptors. Even the \"medium latency\" response was too weak to make an appreciable contribution to restoring the arm to its original position; at the best it provided only 15% of the force required.

Much current thinking about voluntary movement assumes that the segmental gamma loops can function as a servomechanism operated by the brain. However, the alpha motoneurones of the baboon's hand receive a powerful monosynaptic (CM) projection from the precentral gyrus. If servo-driving from the same cortical area is to be possible, it must project independently to the fusimotor neurones and have sufficient power to increase the afferent signalling from the muscle spindles. The cortical thresholds for contraction of m. extensor digitorum communis and for acceleration of the discharges of its muscle spindles have therefore been compared.2. Significant results in this context require that the spindles studied be coupled in parallel with the responding extrafusal muscle fibres. Many spindles were not unloaded by the submaximal contractions evoked by cortical stimulation, although all so tested were unloaded by maximal motor nerve twitches. Reasons are given for thinking that such apparent lack of parallel coupling is an artifact of complex intramuscular anatomy and limitation of shortening by ;isometric' myography.3. A brief burst of corticospinal volleys at 500/sec, which is specially effective in exciting alpha motoneurones over the CM projection, failed to excite spindle afferents at or below the threshold for a cortical ;twitch'.4. In a few epileptiform discharges, bursts of spindle acceleration occurred independently of the clonic contractions. A relatively direct and independent cortico-fusimotor (CF) projection may therefore exist.5. Prolonged near-threshold stimulation at 50-100/sec, which allows time for temporal summation in the less direct projections (e.g. cortico-interneuronal, cortico-rubro-spinal) and does not cause frequency-potentiation at CM synapses, gives abundant evidence of independent alpha and fusimotor projections, whose actions hardly outlast the stimulation period.6. Although independent CF projections would permit servo-driving in natural movements of the hand (given adequate loop gain), there has been no evidence of servo-driving by cortical stimulation or in the spontaneous contractions of light anaesthesia.7. Independent projections would provide for controlled alphagamma co-excitation in the servo-governing of natural movements (Matthews, 1964).8. Evidence is reviewed that the CM projection itself may be part of an important control loop for voluntary movement in primates. A corollary would be a diminished importance of CF projections for segmental loops and an increased importance for maintaining the spindle input to cortical loops.","url":"https://pubmed.ncbi.nlm.nih.gov/4231033/","authors":["Koeze TH","Phillips CG","Sheridan JD"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1968 Mar","doi":"10.1113/jphysiol.1968.sp008466","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:19211001","name":"Intrinsic feedback factors producing inertial compensation in muscle.","source":"pubmed","abstract":"An attempt was made to determine the factors causing the load-inertia compensation that has been observed in skeletal muscle.

Vibration was applied longitudinally to the fully innervated soleus muscle of the decerebrate cat by attaching its tendon to a vibrator. Vibration at frequencies of 50-500/sec with amplitudes of 10 mu upwards caused the muscle to contract reflexly for as long as the vibration was maintained. The response was recorded myographically by a myograph mounted upon the vibrator, and electromyographically by gross ;belly-tendon' leads. The reflex contraction produced several hundred g wt. of tension and involved too many motor units for their discharges to be separable. The maintained reflex was abolished by making the preparation spinal or by anaesthetizing it with pentobarbitone, but it persisted after removing the cerebellum.2. The minimum latency for the appearance of the reflex response at the beginning of a period of vibration was about 10 msec. The latency of cessation of the response at the end of vibration was similarly short.3. On increasing the amplitude of vibration at any particular frequency in the range 100-300/sec the resulting reflex tension increased to an approximate plateau for amplitudes of vibration of 100-200 mu. Further increase in the amplitude decreased the size of the contraction, though there was no such reduction in records of the ;integrated' electromyogram.4. Such large amplitudes of vibration also reduced the tension, and shortened the duration, of a twitch contraction of the muscle elicited by stimulating its nerve. The strength of a tetanic contraction was much less affected by vibration than was that of the twitch contraction, and the muscle action potential elicited by stimulation of the nerve was unaffected. Thus, large-amplitude vibration influenced the contractile mechanism of the muscle (cf. Buchtal &amp; Kaiser, 1951).5. Increasing the frequency of vibration increased the value of the plateau tension reached on increasing the amplitude. The effect was, however, relatively small and the largest increase seen was 3 g wt. of contractile tension per c/s increase in vibration frequency.6. The primary afferent ending of the muscle spindle is considered to be the receptor whose excitation leads to the reflex response to vibration. The vibration reflex thus appears to be the well-known stretch reflex, elicited by a rather unusual form of stretching. The size of the vibration reflex and its variation with frequency are discussed in relation to the servo theory of muscular contraction.","url":"https://pubmed.ncbi.nlm.nih.gov/5921840/","authors":["Matthews PB"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1966 May","doi":"10.1113/jphysiol.1966.sp007926","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:20048799","name":"A recording sampling system for measuring laser energy.","source":"pubmed","abstract":"An apparatus has been designed and built which simultaneously measures the energy incident on a biological system which is being exposed to a laser beam.

Oxytocin can be assayed accurately and the effect of drugs on uterine motility can be measured.","url":"https://pubmed.ncbi.nlm.nih.gov/13918066/","authors":["STYLES PR","SULLIVAN TJ"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1962 Aug","doi":"10.1111/j.1476-5381.1962.tb01433.x","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:13161856","name":"Continuous servo motor integration of the electrical activity of the brain and its application to the control of cyclopropane anesthesia.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/13161856/","authors":["BELLVILLE JW","ARTUSIO JF Jr","BULMER MW"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1954 May","doi":"10.1016/0013-4694(54)90035-8","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"pmid:14822919","name":"Servo-motor integration of the electrical activity of the brain and its applications to the automatic control of narcosis.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/14822919/","authors":["VERZEANO M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"1951 Feb","doi":"10.1016/0013-4694(51)90051-x","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.6084/m9.figshare.32974676","name":"Perancangan dan Implementasi Prototipe Sistem Smart Parking Berbasis Internet of Things Menggunakan Sensor Infrared dan ESP32 (Studi Kasus: Asia Plaza Sumedang)","source":"datacite","abstract":"Keterbatasan informasi ketersediaan slot parkir secara waktu nyata (real-time) menjadi faktor utama penyebab antrean kendaraan dan kemacetan di area komersial seperti Asia Plaza Sumedang.

Ankle plantarflexor stretching extends the maximum range of motion (ROM) during ankle dorsiflexion, decreases muscle-tendon unit stiffness due to passive torque reduction, and improves spasticity of the affected limb in patients with stroke as measured by modified Ashworth Scale (MAS). Previous studies showed that the H-reflex of the soleus muscle in the affected limb decreases during voluntary arm cycling in patients with stroke. As H-reflex reflects motoneuron pool excitability, H-reflex reduction may enhance the expansion effect of soft tissue extensibility by stretching. It was hypothesized that stretching with arm cycling would result in greater ROM and more decreased stiffness in the affected limb of patients with stroke compared with the usual stretching with rested arm.Purpose: This study aimed to ascertain whether ankle stretching combined with arm cycling results in greater improvements in maximum dorsiflexion ROM, calf muscle stiffness, and gait velocity in the affected limb of patients with stroke compared to that without arm cycling.Methods: Nine patients (5 males, age 61.1 ± 11.8 years, BMI 23.0 ± 1.7 kg/m2, time since stroke 8.7 ± 2.5 week, ankle MAS 1~2) who had stroke for the first time and were admitted to rehabilitation wards participated in this study. The inclusion criteria included ability to walk a 10-m distance independently without ankle-foot orthosis. Random ABAB reversal design was used in this study. Participants performed a 10-min ankle stretching using their own weight (non-use arm cycling [NAC], period A), and 10-min arm cycling was added to the stretching performed in period A (added arm cycling [AAC], period B). The participants were instructed to perform the arm cycling as voluntarily as possible with servo motor assistance at 60 revolutions per minute. The affected side of the upper limb was securely fastened to the pedal with a rubber belt. Pre- and post-stretching maximum ROM for ankle dorsiflexion and passive plantarflexor torque were measured using a custom-made passive torque indicator. Stiffness was calculated based on passive torque-angle relationships.Results: As a reference, the pre-stretching data for maximum ROM and stiffness were 18.1 ± 3.2 deg and 48.2 ± 14.9 Nm/rad in all patients. Maximum ROM and stiffness significantly improved after stretching in both conditions. Differences in stiffness between conditions were observed, and the rate of change in stiffness was significantly greater in AAC (-16.8%) than in NAC (-7.9%) (p< 0.05). No significant difference in the rate of change in maximum ROM between AAC (11.4%) and NAC (10.3%) was observed.Conclusion(s): Ankle stretching through weight bearing with arm cycling could more effectively reduce calf muscle stiffness of the affected lower limb in patients with stroke compared with the usual stretching with rested upper limb.Implications: This stretching technique could be conveniently used in the clinical setting, has a low cost, and has clinical importance. Future research needs to investigate whether long-term stretching interventions using this stretching technique would result in long-term effects on ROM and stiffness.Keywords: Ankle stretching, Arm cycling, StrokeFunding acknowledgements: This work was supported by Seijoh University Joint Research Promoting Grant.Topic: Neurology: stroke; Disability & rehabilitationEthics approval required: YesInstitution: Seijoh UniversityEthics committee: Ethical Review Board of Seijoh UniversityEthics number: 2016A0029All authors, affiliations and abstracts have been published as submitted.","url":"https://doi.org/10.82161/acwk-jv59","authors":["Akira Ochi","Masahisa Fukumoto","Ryosuke Takami","Hiroshi Ohko","Takahiro Hayashi","Kazumasa Yamada"],"tags":["Neurology: stroke"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.82161/acwk-jv59","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:43.551Z"},{"id":"doi:10.5281/zenodo.21053142","name":"Gyroscopic Flight Control System and prototype drone","source":"datacite","abstract":"# Coordinated Counter-Rotating Gyroscopic Ring Actuation for Enhanced Three-Axis Attitude Control in Multirotor Aircraft **Author:** Adam L.

Conventional multirotors generate roll and pitch torque from thrust differential (strong) but produce yaw torque only from motor reaction drag (weak); yaw is universally the limiting axis. The system described here uses gimballed, spinning rings to produce precession torque on all three body axes, with a coordinated bias-angle strategy that converts the otherwise-uncontrollable yaw direction into a fully actuated one. I derive the ring precession torque from first principles using the *true* finite-angle angular velocity of the tilted gimbal frame, prove that the resulting body torque is exactly the negative time-derivative of ring angular momentum (i.e. the gyros transfer momentum rather than create free torque), and validate this against zero-input conservation tests to numerical tolerance. I add physically credible actuator limits (servo speed–torque curves, thermal derating, gear backlash, bearing drag, and ring spin dynamics), CAD-grade full inertia tensors with uncertainty bands, a reachable-torque-envelope analysis, a 500-trial Monte Carlo robustness study, a controller-baseline comparison, and an ablation study of an experimental Fractal Correction Engine (FCE) predictive layer. On the identical 1.95 kg airframe, the gyroscopic system delivers approximately **6× the yaw torque** and a far more balanced yaw-to-roll authority ratio (1 : 3.7 versus 1 : 7.1) compared with a conventional quadcopter, and roughly **20× better impulsive-gust disturbance rejection**. A discovered hover roll limit-cycle, caused by a standing ring bias, is eliminated by demand-gating the bias, reducing hover roll RMS from 12.5° to 0.00° while fully retaining on-demand yaw authority. The FCE is shown to provide no genuine look-ahead advantage over a simple velocity predictor; its closed-loop benefit is an incidental proportional-feedback effect, and it is therefore retained only as an experimental, ungated feedforward layer. --- ## 1. Introduction Multirotor aircraft are now ubiquitous, but their control authority is fundamentally asymmetric. Roll and pitch torques arise from differential thrust across a moment arm and are strong; yaw torque arises only from the aerodynamic reaction (drag) torque of the propellers and is an order of magnitude weaker. This makes yaw the limiting axis for disturbance rejection, agile heading changes, and stability in wind. A control-moment gyroscope (CMG) stores angular momentum in a spinning rotor and produces torque by reorienting (gimballing) that rotor: `τ = ω_g × H`. CMGs are the workhorse of spacecraft attitude control precisely because they produce large, fast torques without expending propellant. This work asks whether a compact CMG array — three concentric counter-rotating rings on two-axis gimbals — can be embedded in a quadrotor airframe to give it strong, balanced three-axis authority, especially in yaw. I built a single-file digital twin of a CNC-machined prototype and progressively hardened its scientific rigor across seven areas: (1) locking the gyroscope ","url":"https://doi.org/10.5281/zenodo.21053142","authors":["McEvoy, Adam L"],"tags":["thedr"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.21053142","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:43.481Z"},{"id":"doi:10.17632/g28trvywnx.4","name":"Multi-Sensor Condition-Monitoring Dataset of a Brushed DC Servo Motor","source":"datacite","abstract":"Dataset Short Description This dataset contains raw multi-sensor recordings from a brushed PM DC servo motor (3PI12.12) operated under multiple conditions and load levels.

This episode unpacks the three-phase logistics of Israel's reported Operation Rising Lion: smuggling components disguised as industrial parts, assembling them in a covert workshop near Tehran, and activating them to strike Iranian missile launchers. We explore the \"IKEA approach\" to covert operations — shipping flat-pack death, assembly required — and how the drone revolution's dual-use supply chain makes it possible. Show Notes This episode examines the remarkable logistics behind claims that Israel pre-positioned explosive drones inside Iran and used them to destroy surface-to-surface missile launchers during the opening hours of Operation Rising Lion on June 13, 2025. The core operational insight is simple: you don't smuggle completed drones across borders. You smuggle components — circuit boards, motors, carbon-fiber tubes, batteries, servo actuators — that become drones after assembly. None of these parts individually looks like a weapon. They pass through customs as commercial electronics or industrial supplies. The smuggling phase relies on patience, compartmentalization, and hiding in plain sight within legitimate commercial flows. Components are drip-fed through multiple channels over months or years: carbon-fiber tubes described as irrigation boom replacement parts, flight controllers packed inside legitimate electronics shipments, motor assemblies mixed with HVAC repair gear. Front companies — real businesses that mostly conduct legitimate operations — provide cover for the 5% of shipments that matter. Iran's sanctions environment paradoxically helps, as a sophisticated parallel smuggling economy already exists for consumer goods, creating infrastructure that drone components can piggyback on. Phase two involves storing and assembling the drones in safe houses near Tehran. Components are distributed across multiple locations to prevent catastrophic loss if one cache is discovered. The assembly site only receives parts shortly before activation, minimizing the vulnerability window. The drones themselves are designed for rapid assembly by non-specialists using hand tools — modular connectors, pre-wired harnesses, snap-together airframe sections. This \"design for clandestine assembly\" philosophy optimizes for speed and foolproof alignment, similar to flat-pack furniture principles. The tradeoff is proximity versus security: being close to targets reduces flight time and interception risk, but operating in the heavily surveilled Tehran metropolitan area is extremely high-risk.

Innovations come about be- cause of pressures, in particular financial pressures, and access to care. With increasing interoperability of devices, distinction is made between devices with specific interoperability (SIO) only able to communicate with a pre-determined range of other devices, and non-specific interoperability (NSIO). Devices with NSIO pose substantially greater potential benefits by allowing long-term system wide innovations. Scales of innovation are discussed, where short-term innovations meet an immediate need, such as the inundation of intensive care units (ICUs) in the COVID-19 pandemic. Medium-term innovations see either incremental increase in efficiencies, or an increase in interoperability which enables subsequent innovation. Long-term innovations are disruptive, systemic changes, often enabled through the use of increasing interoperability. The uptake of innovation is often lacking, but through the use of a framework such as Tech-ISM the chance of adoption is increased. This framework sees establishment and fostering of close relationships with a range of end users, decision makers, and industry partners. Diabetes technologies are presented as examples of innovation. Insulin pumps are an effective method of delivering insulin, and see considerable benefit in control. Widespread adoption of insulin pumps is posed through the development of an ultra-low cost (ULC) insulin pump, made possible by the separation of hardware and computation, and costing 12 × −20× less than currently-available devices, both for a traditional-style insulin pump, and also a novel spring-driven design. Initial results show similar accuracy to current commercially-available insulin pumps, with a mean error of 0.64%, the same as the MiniMed™640G (Medtronic, Dublin, Ire- land) for 1 U boluses, and mean error of 0.06% for 10 U boluses. Basal windows of 1 hour are similarly accurate, with 100% within ±15%, 92% within ±10%, and 84% within ±5%, again very similar to the MiniMed™640G. The ULC insulin pump is a solution to the economic infeasibility of insulin pumps for the majority of New Zealanders. System-wide adoption of insulin pumps would see considerable economic benefit for New Zealand, in particular with a patch pump. Several possible adoption scenarios are presented. Annually, direct savings associated with less insulin use and current public investment in insulin pumps is expected to total $6.6M - $25.3M, indirect savings from reduction of expensive complications are expected to save $2.5M - $25.5M, with direct costs of $0.8M - $25.7M. Projections are for a total overall system saving of $8.3M with no additional uptake of insulin pumps, but only replacing current insulin pumps with the ULC alternative, to $25.0M with widespread adoption. These figures do not account for additional savings made possible through future long-term development of smart, automated healthcare systems. A continuous glucose monitor (CGM) is a device that estimates blood glucose (BG) every 1-5 minutes, replacing discrete, invasive self-monitored blood glucose (SMBG) measure- ments as required four to ten per day currently for approximately 40,000 - 60,000 New Zealanders with diabetes who administer insulin. Current CGM use is limited, but rel- atively unknown, due to no public funding, with expert estimates at 2-8% prevalence among individuals with type-one diabetes. A low-cost alternative is presented in the form of the blood optical biosensor CGM (BOB CGM) at an annual cost 10 × −20× less expensive than current devices. Initial, un-calibrated results show promise, with 91% of BG results deemed clinically accurate, and a further 8% sufficiently accurate to not cause treatment error. Fundamentally, cost savings arise from allowing access to otherwise inaccessible data, and thus turning the current data monopoly into a data market.

However, this effect has yet to be investigated in mammalian skeletal muscle. Therefore, we exposed isolated mouse soleus and extensor digitorum longus (EDL) muscles to a graded series of hypotonic solutions to promote fluid uptake while measuring passive force development, muscle mass, and 2D projected muscle area. Normalized to the tension measured at 1.2 L0 in isotonic Ringer’s solution, the relative passive forces in the soleus were 1.14, 1.31, 1.52, and 1.92 in 70%, 60%, 55%, and 50% relative tonicity, respectively. Comparable values for the EDL in relative tonicities of 70%, 60%, and 55% were 1.13, 1.78, and 2.10, respectively. In both muscles, increases in passive force were accompanied by increases in mass and projected area. We also investigated the effect of muscle tension on fluid uptake. Soleus muscles left slack and allowed to shorten when exposed to a hypotonic solution gained much more mass compared to muscles held at the predicted length for maximal active force production, which suggests that at this length water uptake is limited by the buildup of hydrostatic pressure. Our findings support the hypothesis that in mammalian muscle, intramuscular fluid volume is an important determinant of passive force development. These results could have implications for human movement performance, where muscle volume change has been observed in vivo.","url":"https://doi.org/10.5061/dryad.d7wm37qdx","authors":["Falcone, Samantha","Marsh, Richard","Cairns, Ofubofu","Roberts, Thomas"],"tags":["FOS: Biological sciences","FOS: Biological sciences","Muscle physiology","intramuscular fluid","passive force development"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5061/dryad.d7wm37qdx","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.5281/zenodo.20356286","name":"PhotoBot: An Automated Smart Photography Robot Using Computer Vision and Servo-Controlled Camera Mechanism","source":"datacite","abstract":"Abstract Group photography at tourist locations presents a long- standing challenge at least one mem-ber of the group must step out to operate the cam-era, thereby being excluded from the photograph.

In the last years, linear electrical drives, especially the long-stator linear motors are used for these types of applications for both processing and transportation tasks. They have higher dynamics and processing precision and lower maintenance costs compared to conventional systems, which require additional mechanical gears. The linear drive system must be modular and highly scalable in order to cover a wide range of applications. For this reason, the track of the plant is made of several stator segments. The excitation part of the motor is represented by permanent magnets (passive vehicles). Each stator segment has a dedicated inverter (Power Processing Unit) and processor (Information Processing Unit). Cheap IPMs (Intelligent Power Modules) are nowadays a good solution for implementing the inverter. A DSP was used as processor. The DSP and the IPM are the main components of the designed servo-controller, which together with a stator segment represents a module of the system. The DSP controls the inverter and is also used for the communication with the DSPs of the adjacent modules. By connecting the ground potential of all servo-controllers to the negative DC-link rail (ca. -280V), a significant reduction in the implementation costs of the servo-controller was achieved. When a vehicle crosses from one stator segment to the adjacent one, the control tasks migrate physically in that respective adjacent DSP. Data exchange is therefore required within each cycle of the current control loop (100 µs) between the adjacent modules. For an arbitrary scalable modular system, there will be also an arbitrary high communication demand. This demand can only be solved by a direct (Point-to-Point) connection between the adjacent DSPs. This connection was realised by means of the cost-effective RS485 data transmission protocol. A central control unit is responsible then for the cyclical (1-10 ms) generation of new position reference values for the vehicles, according to a predefined schedule. The monitoring (assessment of internal variables of the distributed servo-controllers) of the entire system is realised also in real-time. Off-line download and upload actions of firmware or general data is also possible. For these tasks, the communication between the central unit (PC) and the distributed servocontrollers was realised by means of the Ethernet-based fieldbus EtherCAT. Inside the processing stations of the system, the positioning accuracy and precision as well as the dynamic have to be very good. For this reason, inside those stations, position sensors must be used. Outside those stations, for material transportation only, an EMF-based sensorless control was implemented. This will further reduce the overall system costs. A small section of such modular and highly scalable system was realised as an experimental set-up in the context of this work, in order to test the functionality and the reliability of the proposed system.","url":"https://doi.org/10.26083/tuprints-00002949","authors":["Silaghiu, Sorin Mihail"],"tags":["600","620"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2012","doi":"10.26083/tuprints-00002949","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.26083/tuprints-00000553","name":"Speed Acquisition Methods for High-Bandwidth Servo Drives","source":"datacite","abstract":"A servo control needs the actual values of speed and position.Usually, the latter is computed from the signals of a position encoder; its 1st derivative is smoothed by a low-pass filter and used as actual speed signal. A number of enhanced and alternative methods is experimentally investigated in this thesis. Based on an equal steady-state behavior, the controlled servo's dynamic stiffness is used as the performance measure. The used setup has a special feature: because of its rather high resonant frequencies (870 and 1280Hz), the encoder's oscillation against the drive can no longer be neglected. The mechanical resonance can be met by using notch filters to damp the resonant frequencies out of the controller spectrum, leading to major improvements. By identifying and modeling the mechanical setup at different levels of precision, observers were designed to provide an alternative actual speed signal, leading to a further improvement; however, active damping was not possible due to the configuration of the resonant system. The use of a state controller allowed active damping, but at the expense of reducing control gain and thus dynamic stiffness. The signals of an optical position encoder show characteristic errors. Using measures to correct those errors, it was tried to improve steady-state speed quality and allow a higher control gain. Two table-based and one on-line adaptive method were investigated. As stated in previous works, the correction of signal records resulted in a considerable error reduction with all methods. However, the improvement due to correction used in the control loop is small, because the loop gain is quite low at the error signals' high frequencies. The use of an acceleration sensor for speed acquisition has the advantage that the signal is integrated instead of derived, reducing noise instead of amplifying it. The improvement in the experiments was only low, because oscillation and not noise is the problem limiting control gain. Another advantage of the acceleration sensor is a much easier fixing compared to the position encoder. By mounting the acceleration sensor at an optimal location concerning oscillation, it is possible to damp the oscillation considerably without any knowledge about the resonant frequencies. The thesis is completed by theoretical investigations of speed quality and dynamic stiffness, investigations of drive-side and load-side behavior and necessary computation power for the investigated algorithms.","url":"https://doi.org/10.26083/tuprints-00000553","authors":["Bähr, Alexander"],"tags":["motion control","servo motor","mechatronics","oscillation damping","acceleration sensor","optical position encoder","observer","filter"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2008","doi":"10.26083/tuprints-00000553","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.18130/dc7m-dt40","name":"ICARUS-1: The Next Step in UAS Propulsion; Actor-Network Theory Analysis of DARPA's Micro-UAV Programs","source":"datacite","abstract":"In recent history, advancements in unmanned aerial systems (UAS) have enabled new possibilities in environmental monitoring, reconnaissance, and search-and-rescue operations, yet conventional drones remain constrained by fundamental limitations in flight efficiency, maneuverability, and endurance. Fixed-wing aircraft are efficient but require continuous forward motion and open space to operate, while multirotor systems can hover and maneuver precisely but rely on powerful actuation that limits flight time. These tradeoffs restrict deployment in environments such as forests, collapsed structures, or urban areas where adaptability and precision are critical. To address these restrictions, ICARUS-1 draws on the mechanics of dragonflies to develop a four-wing flapping UAS capable of hovering, directional control, and precise maneuvering within strict mass and power budgets. Dragonflies have four independently actuated wings allow for dynamic modulation of lift and thrust through adjustable phase relationships, enabling hovering, rapid directional changes, and backward flight within a single lightweight structure, a unique capability not utilized in any modern technologies. Drawing on this biological model, the ICARUS-1 team designed and prototyped a dragonfly-inspired UAS incorporating four independently driven wing assemblies controlled through a custom circuit board and microcontroller. Wings were developed through extensive iteration, ultimately achieving a dramatic mass reduction from the initial design through the adoption of carbon fiber rod spars within a vacuum-sealed film. A dedicated thrust test bench was used to validate lift generation and wing dynamics across the system. The ICARUS-1 development process was characterized by mechanical roadblocks that need to be surpassed through iterative design and critical thinking. Early motor configurations were abandoned after failures under the oscillating load; servo-based control systems were simplified after noticing actuation instabilities at required frequencies; and the airframe was restructured multiple times to limit the mass. These revisions reflect the degree to which material constraints, aerodynamic behavior, and system-level interactions shaped the final design as much as any of the mission objectives did. This negotiation, however, did not occur in a vacuum. The development of micro-UAVs is not simply a technical problem of achieving efficient flight on a small scale but is fundamentally a sociotechnical challenge shaped by interactions among institutions, engineers, biological models, materials, and societal concerns. While these systems offer potential benefits for civilian applications, their maneuverability and miniaturization also make them highly suitable for covert surveillance and military operations. Because these competing uses are characteristic of the designs themselves, their development raises significant ethical concerns related to privacy, militarization, and environmental disruption; concerns that cannot be resolved by engineering decisions alone. The accompanying STS report addresses this directly by applying Actor-Network Theory to DARPA's Micro Air Vehicle and Nano Air Vehicle programs, examining how a network of human and non-human actors has and continues to shape the trajectory of bio-inspired flight. ANT provides a framework for understanding how government agencies, engineers, biological systems, aerodynamic forces, and material constraints interact to produce specific outcomes. Through this lens, DARPA functions as the obligatory passage point through which all actors must align to participate in the network; enrolling universities, private contractors, biological organisms, and design constraints in service of a surveillance-oriented program definition. The Nano Hummingbird and RoboBee are examined as case studies in network stabilization, demonstrating that technological success is not a product of engineering performance alone but also ","url":"https://doi.org/10.18130/dc7m-dt40","authors":["Zach, George"],"tags":["Dragonfly","Robotic","ANT","DARPA","UAS"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.18130/dc7m-dt40","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0074490","name":"Front-wheel friction drive electric bicycle motor","source":"datacite","abstract":"Many cyclists are seeking easy solutions to bring electric power to their bikes. Having an electric motor that can be switched on to get a boost going uphill, to go faster, or to simply take a break from pedaling can be very useful. With these motivations, we sought to develop a front-wheel friction-drive motor system that could be easily mounted and removed from any adult-sized road bike. The objective was to develop an easily mountable solution containing the motor, controller, battery pack, and throttle that could be installed within minutes. Friction-drive motors are a cheaper, lighter alternative to the more common hub motors that must be permanently attached to the wheel of the bike. Indeed, the motor mechanism component of our design weighs 1.45 kg, and the total weight of our design does not exceed 3 kg (depending on the size of battery pack used). The design of our solution was based on goal of keeping the installation as simple as possible, whilst ensuring that the mechanism could tolerate the strong rotational forces introduced by the motor. Our solution mounts at the handlebars by means of two snap-on clamps, as well as at the fender holes, located at the hub of the front wheel of the bicycle. The design can be adjusted at two locations: by changing the angle between a horizontal and a vertical cantilever, as well as by changing the height of the supporting rods. The motor is attached to a pivot point, such that is has sufficient room to engage and disengage with the front tire. Blocker pieces are located strategically to ensure that the motor does not swing too far back and get stuck in the wheel. The mechanical aspect of our solution has proven to be successful. We were able to mount the mechanism to five different bicycles, all of which varied greatly in handlebar shape and tire size. In all these cases, our solution was easily installed in under two minutes. Installing a user-friendly throttle proved to be very challenging. The most successful attempt entailed running the controller by means of a purchased servo tester circuit; however, our throttle setup was not functioning in time for us to do test ride our solution. We therefore cannot present meaningful results as the electrical efficiency of our system. We recommend three important actions to be taken to ensure that our solution be safe and fully-functional. First, all electrical parts should be protected in a water-proofed enclosure. Secondly, a push button throttle should be installed along with the servo tester circuit. Finally, we recommend that an emergency brake be installed to ensure the safety of the user in the case where the throttle or controller fails.","url":"https://doi.org/10.14288/1.0074490","authors":["Chen, Oliver","Ghoussoub, Mireille","Zhou, Cherry"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2013","doi":"10.14288/1.0074490","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0074480","name":"Sand-painting Autonomous Nomadic Depositor (S.A.N.D.)","source":"datacite","abstract":"The purpose of this project is to design and develop a low-cost, portable, and autonomous sand painting robot. The robot uses 6 different colours in its sand painting and covers an area up to 6m x 6m fully with 1cm x 1cm sand pixels. It can be assumed that the surface the robot works on is dry, even, and level, and that there is no wind present. A simple computer interface to the robot is provided which allows the user to input the physical dimensions of the room the robot is allotted, the image the robot is to paint, and other information to direct the robot. The robot operates in an x-y plane in a printer-like fashion, with stepper motors driving omni-wheels. The sand deposition system is gravity-fed, with servo motors controlling the sand flow out of 6 sand canisters. Two laser distance meters are used to track the position and alignment of the robot. The system would consist of wireless communication via Xbee between the robot and a laptop. The laptop serves as a control centre for directing the robot’s movement, sand dispensing, refilling, etc. After testing, the robot has met requirements for consistency of amount of sand delivered in sand shots, movement precision between pixels, and the time required for the robot to distribute sand per pixel. However, at the current stage of development, not all components of the robot are fully finished. Sand level measurement using IR sensors have not been implemented and the integration of position tracking via laser distance meter in the operation of the robot has yet to be completed. While the GeckoDrive boards currently used to control the stepper motors are functional, due to their expense, an alternative driver board, A4983 Pololu stepper motor driver carrier, would later replace the GeckoDrive board instead.

In Experiments 1-3 participants received 1, 000 trials to learn a 90° out-of-phase task. The secondary task from which attention demands were derived was probe reaction time (probe-RT). Although cognitive demands decreased with practice, results showed that performance of the 90° pattern continued to demand attention, even after extended practice. Similar results were found in Experiment 4 when examining the attentional costs of performing naturally occurring coordination tendencies (i.e., in-phase, anti-phase). These findings indicate that a minimal level of cognitive control is required for the execution of newly acquired bimanual coordination tasks, as well as for the performance of intrinsic coordination biases. These experiments also examined the influence of continuous on-line visual feedback on learning and attention demands. Individuals received concurrent visual feedback for 65% of each practice trial (Experiment 1) or for only 35% of each trial (Experiment 2). Results showed that participants were highly successful at producing the required task when visual feedback was available, but were less able to inhibit the influence of pre-practice biases whenever visual feedback was unavailable to guide performance. Experiment 3 examined the influence of manual guidance on performance of the 90° pattern under limited conditions of visual feedback. When participants' limbs were physically moved through the required movement via servo torque motors individuals were better able to break away from pre-existing tendencies. Finally, Experiment 5 revealed that probe-RT was slower when performing in the absence of visual feedback, in comparison to its presence. Attentional requirements also increased whenever the dominant source of feedback was changed within a trial, although adding visual feedback to the perceptual display resulted in only a temporary increase in probe-RT. In addition to examining the attention demands of bimanual coordination, these investigations highlight the importance of exploring instructional strategies that reduce the negative effects of pre-existing behavioural tendencies on the learning of new complex motor tasks.","url":"https://doi.org/10.14288/1.0077415","authors":["Bredin, Shannon Stephanie Deanne"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0077415","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0078711","name":"Fundamental study of the controlled-potential leaching of chalcopyrite","source":"datacite","abstract":"There is a well-established trend in copper hydrometallurgy to develop processes for the treatment of chalcopyrite ( CuFeS₂ ). Chalcopyrite receives considerable attention not only because of its relative abundance and widespread distribution in almost all sulfide deposits, but also because it is the most recalcitrant copper sulfide to leaching in most practical systems, particularly in sulfate media. The main practical difficulty encountered in the commercial acid ferric sulfate leaching of chalcopyrite (in heaps, dumps or concentrates) is its slow rate of reaction, which renders a long residence time and/or incomplete copper extractions. Chalcopyrite is generally agreed to be \"passivated\" in some fashion, exhibiting slow leaching kinetics and low copper extraction in sulfate media. This thesis work investigated the oxidation of chalcopyrite through the application of controlled-potential at different potentials (0.400-0.600 V[sub Ag/AgCl]) and temperatures (60-78°C). All experiments were carried out in a compact bench-scale 3-L glass jacketed bioreactor equipped with a servo motor and speed controller. Since the solution redox potential is dependent on the concentrations of ferric and ferrous ions in solution, a constant redox potential was maintained by controlled addition of potassium permanganate using an automatic titration unit. Chalcopyrite leaching in sulfuric acid is shown to be dependent on solution redox potential determined by the concentration ratio of ferric to ferrous ions and temperature. The most significant finding in this thesis work is the fact that the leaching; rate increases with increasing potentials but decreases above a critical potential under the reaction conditions studied. This critical potential is in the vicinity of 0.500 V[sub Ag/AgCl] and is within the mid-potential range of 0.45 to 0.55 V[sub Ag/AgCl] at which the leaching rate is maximal from 60 to 78°C. Leaching rates increase with increasing temperature. The leach residues contain sulfate (5- 33%), but primarily elemental sulfur (46-78%). XRD analysis confirmed the presence of sulfate sulfur, jarosite, and elemental sulfur in the leach residues. SEM analysis suggests that neither jarosite nor elemental sulfur is responsible for surface passivation or for preventing, the dissolution of chalcopyrite.","url":"https://doi.org/10.14288/1.0078711","authors":["Lai, Jerry Cheng-Yen"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0078711","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0080972","name":"A dynamically reconfigurable system architecture and FPGA based servo controller for distributed machine tool control","source":"datacite","abstract":"This thesis presents the design and analysis of a novel system and protocol for the automatic configuration and dynamic reconfiguration of distributed machine tool control systems.

To integrate the controller of a high speed servo-motor with the tuning knowledge of experienced system operators, a hierarchical control structure is developed in this research. Specifically, the programmable hard controller of a servo-motor is tuned automatically in the lowest level.

High-fidelity models are essential to capture the intricate dynamics of IPMSMs, particularly in scenarios demanding computational efficiency and minimal memory requirements. Field-oriented control (FOC) is a widely adopted strategy for IPMSM drives, enabling precise torque and flux control by decoupling the stator current components. However, FOC implementation in IPMSM faces challenges due to the machine’s nonlinear flux-current relationships, which are influenced by factors such as saliency, magnetic saturation, and cross-coupling effects. Furthermore, the flux linkage in IPMSMs can vary significantly with design parameters and operating conditions. Traditional qd models often rely on extensive look-up tables (LUTs) to accurately map flux-current relationships. These LUTs may be obtained from the finite-element analysis at the motor design stage or experimentally for a considered motor prototype, and they can demand substantial memory resources and computational overhead, particularly for wide operating ranges. This thesis introduces innovative models for IPMSM drive systems, focusing on their integration within state-variable-based (SVB) electromagnetic transient (EMT) simulation platforms.

A robust monitoring system, coupled with the ability to use machining state signals predicted by the digital model is key to the implementation of such systems in production environment. This thesis presents the use of machining simulations to CNC-inherent or accessible data collected from sound, vibration, and force sensors. Through the combination of simulations and on-line measurements, a digital twin is created to detect chatter, tool breakage, and tool wear. First, the machining process states such as force, torque, power, and cumulative chip removal are simulated along the tool path. The actual and virtual positions of the tool along the tool path are synchronized during actual machining so that measured and simulated states can be compared. A new tool wear monitoring algorithm is proposed. The cutter – workpiece engagement area and cumulative chip removed by the cutting edge are computed using the Virtual Machining Software developed in the laboratory. The spindle servo motor current is collected from the CNC and normalized by the engagement area. The tool wear is correlated to cumulative chip thickness and an increase in the geometry-independent spindle motor current using a few tool wear measurements. It is shown that the tool wear progress can effectively be monitored by integrating simulation and motor current extracted from the CNC system. Similarly, chatter is also detected from sound spectrum measurement along the tool path by differentiating it from the air cut, transient vibrations and changes in the workpiece geometry with the aid of digital simulations. Chatter detection and avoidance algorithm is also enhanced by deactivating it at transient cutting zones. In some applications such as adaptive force control, it is necessary to measure cutting forces during machining.

The cutting force provides important information about the state of the process and cutting tool because it correlates to the physics-based mathematical model of the process. This thesis presents methods for the estimation and prediction of cutting forces from the spindle and feed drive motor current data extracted from CNC. The spindle motor current is correlated to inertia, friction in the bearings, and cutting torque as a disturbance in closed-loop spindle speed controller. The Frequency response function (FRF) of the spindle servo drive is measured via a built-in CNC function. The state-space model of cutting torque disturbance of the spindle drive is modeled. Kalman Filter and Regularized Convolution (RD) are used to compensate the disturbance effects of electrical and mechanical dynamics to widen the bandwidth of cutting torque estimation from spindle motor current. Automatic tuning of Kalman Filter’s covariance and RD’s regularization factor is investigated by checking the Neural Network-based online tuning of Kalman Filter and the off-line L-curve tuning of both estimators. The proposed methods are experimentally illustrated in milling operations. It is shown that Kalman Filter can estimate the cutting forces on-line during machining. RD is used only in off-line estimation due to its computational cost, although it has higher accuracy due to its compensation at a wider frequency range. L-curve only achieves offline tuning due to its computational cost. Neural Network can auto-tune the estimator, but training the network requires high computational efforts. The feed drive motor current commands are used to predict the cutting forces in Cartesian coordinate system. The previous research illustrated that Kalman filter estimates the periodic cutting forces up to about 150 Hz bandwidth, provided that the FRF is not position-dependent, and friction is compensated. This thesis presents the use of average motor current to estimate the average cutting forces after friction compensation. The average forces are used to monitor the variation in cutting force coefficients which is used to calibrate the process simulation models in a digital twin environment.","url":"https://doi.org/10.14288/1.0421417","authors":["Ji, Zeen"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.14288/1.0421417","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0395180","name":"Automated design and implementation of Kalman observer for spindle torque estimation in CNC machining","source":"datacite","abstract":"Milling is a subtractive manufacturing technique, where the material is continuously removed from a workpiece until the desired part shape is obtained. Heavily used in the automotive and aerospace industries, Computer Numerical Control (CNC) milling machines occupy a large chunk in the manufacturing process. The current research focuses towards machining and machine tool monitoring systems that are more self-sufficient and self-adjusting to adapt the processes to machine tools. Cutting torque delivered by the machine tool spindle is one of the key sensory signals for machining process monitoring. This thesis presents a method that automatically reconstructs cutting torque from motor current commands generated by the servo controller of the machine tool. To estimate the cutting torque from commanded spindle current, the dynamics between torque to current relationship must be modeled and compensated. The thesis first presents an automated identification of spindle dynamics using data-driven system identification methods. The frequency response function (FRF) of the spindle dynamics is measured manually using CNC internal diagnostic tools. The identified FRF is then automatically converted to a state-space model using the Eigensystem Realization Algorithm (ERA). To reduce overfitting, an optimal threshold is applied to the ERA method to limit the identified system order. And to ensure the stability of the identified system, unstable eigenvalues of the system are removed using Schur decomposition. The identified system is then augmented such that the unknown torque input is modeled as a state changed by a random process noise. This augmented system is used to create a Kalman Observer, which compensates the spindle dynamics and estimates the torque from the spindle nominal current. The Kalman Observer is tuned automatically by estimating the noise covariance values using machining simulations. The method was eventually validated on a Quaser UX 600 industrial CNC system.","url":"https://doi.org/10.14288/1.0395180","authors":["Lu, Zhao Wei"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.14288/1.0395180","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0394086","name":"Touchscreen-friendly fingertip system for tactile feedback in prosthetic hands","source":"datacite","abstract":"Today’s prostheses provide numerous intuitive features including several gripping patterns and movements guided by the user’s intentions. Nevertheless, users remain quite dependent on visual and auditory cues when trying to adjust grip forces, and are still unable to use their touchscreens with prosthetic fingertips. To approach this problem, researchers have proven that sensory feedback can help amputees to be faster and more accurate when accomplishing a task. However, there is still a need for a low-cost and adaptable sensory feedback add-on, requiring minimal modifications to the hand. This thesis presents the development of a low-cost sensory feedback system, including a stimulation device and a force sensing fingertip that comprises a capacitive sensor. The novelty of this research is the ability of the fingertip to activate touchscreens, and the full fingertip integration to the prosthetic hand, under the prosthetic glove – easy for the user to maintain. The glove integrated sensor capacitively detects forces over an area of 0.64 cm2. This detection is linear up to 1.6 N, with a resolution of 0.01 N. The second part of this thesis presents the implementation of shear detection, in addition to touch and pressure, using a modified sensor on a flexible printed circuit board. Able to detect touch, pressure, and shear simultaneously, the sensitive fingertip can send sensory feedback to the user. The last part of this thesis presents the implementation of two sensory feedback: one using an armband including a servo motor pushing on the user’s stump (mechanotactile feedback), and one using vibration motors hidden in the socket (vibrotactile feedback) – two feedbacks that are preferred based on a survey that we conducted. It was found that vibrotactile feedback would be more efficient due to its complete integration to the hand and its ability to send shear feedback. The next steps are the implementation of Bluetooth connections for wireless stimulation and the development of a user iv interface for real-time calibration. An ethics approval to test the device on patients was granted and will be put into practice to understand the benefits of the device and gather users’ opinions.","url":"https://doi.org/10.14288/1.0394086","authors":["Dupont, Bertille"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.14288/1.0394086","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0314220","name":"Prediction of cutting forces at the tool tip using drive current for five-axis machines","source":"datacite","abstract":"The current trend in industry is to achieve intelligent, Computer Numerical Controlled (CNC) machine tools which can monitor its performance and take corrective actions automatically during machining operations. Cutting forces are the most accepted indicators of the tool condition, load on the machine and part, and abnormalities in the machining operations. The objective of this thesis is to predict the cutting forces from the current drawn by each drive during five axis machining operations. The cutting forces generated at the tool–workpiece contact zone are transmitted to the three translational and two rotary drive motors through ball screws and gear boxes. The torque received by individual motors is transformed as disturbance current by the motor amplifiers. The cutting force transmitted to each feed drive acts as a disturbance to the closed loop servo controller, which reacts by supplying torque command in addition to the torque required to overcome the friction and inertial motions. The accurate prediction of cutting forces from the motor current measurements requires the separation of the effects of cutting and inertial motion forces from the total motor current values. The transfer function between the applied force at the tool tip and motor current is identified at each drive. The effects of structural modes are canceled through extended Kalman Filter designed for each drive. Both Coulomb and Viscous Friction forces have been identified, and their effects are also removed from the state measurements of all drives. The cutting forces at the tool tip are predicted by applying extended Kalman Filter on motor current signals, and transmitting them to the tool tip through forward kinematic model of the machine, the contributions are proven using machining tests conducted on a five axis machining center.","url":"https://doi.org/10.14288/1.0314220","authors":["Tuysuz, Tugce"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2016","doi":"10.14288/1.0314220","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0072107","name":"Modelling and control of feed drives","source":"datacite","abstract":"Feed drives are used in positioning of machine tools. The drives are actuated either by linear or rotary servo motors. The ball screw drives are driven by rotary motors; hence they have flexibility and added friction due to nut interface. Direct drives are driven by linear motors which have more mechanical stiffness, but less disturbance rejection due to missing load reduction mechanism. This thesis presents the modelling and control of drives with rigid and flexible structures. A single degree of freedom flexible oscillator is mounted on a high speed, rigid feed drive table for experimental illustration of system identification and the active control method proposed in the thesis. The rigid feed drive dynamics include the mechanical component of the rigid body mass and viscous damping, and the electrical component of the power amplifier and motor. The flexible component is modelled by springs, mass and damping elements. Both rigid and flexible dynamics of the system are identified experimentally through unbiased least square, sine sweep and impact model tests. The vibration of the single degree of freedom system is actively damped by an acceleration feedback inserted in the velocity loop. A Kalman filter is used to minimize the drift and noise on the acceleration measurements. The position loop is closed with a proportional controller. It is experimentally demonstrated that the vibrations of the flexible structure can be well damped. However, the acceleration feedback used at the resonance frequency greatly minimizes the bandwidth close to the vibration frequency. Further methods need to be used to expand the bandwidth beyond the natural frequency of the flexible structure by coping with the anti-resonant effect of the acceleration feedback.","url":"https://doi.org/10.14288/1.0072107","authors":["Ng, Kenneth"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2011","doi":"10.14288/1.0072107","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0067853","name":"Smooth trajectory generation and precision control of 5-axis CNC machine tools","source":"datacite","abstract":"This thesis presents experimentally verified optimal feedrate generation and high performance precision control algorithms developed for 5-axis machine tools. A feedrate scheduling algorithm has been introduced to minimize the cycle time for 5-axis machining of curved tool-paths. The variation of the feed along the tool-path is expressed in a cubic B-spline form as a function of the arc displacement. The velocity, acceleration and jerk limits of the five axis drives are considered in finding the most optimal feed along the tool-path to ensure smooth and linear operation of the servo drives with minimal tracking error. Improvement in the productivity and linear operation of the drives are demonstrated through 5-axis experiments. In an effort to design an accurate contour controller, analytical models are developed to estimate the contour errors during simultaneous 5-axis machining. Two types of contouring errors are defined by considering the normal deviation of tool tip from the reference path, and the normal deviation of the tool axis orientation from the reference orientation trajectory. A novel multi-input-multi-output sliding mode controller is introduced to directly minimize the tool tip and tool orientation errors, i.e. the contouring errors, along the 5-axis tool-paths. The stability of the control scheme is proven analytically, and the effectiveness of this new control strategy has been demonstrated experimentally. An identification technique for identifying the closed loop transfer function of machine tool feed drives has been introduced. The drive system is identified in closed loop, including the feed drive mechanism, motor amplifier, and the control law. A short Numerical Control Program is used for exciting the axis dynamics without interfering with the servo control loop. A generalized drive model is utilized to capture the key dynamics of the drive systems, while guaranteeing the stability of the identified model dynamics by solving a constrained optimization problem.

Their application to other 5-axis machines would require modeling of the kinematic chain and the drive dynamics to be considered in the control law design and trajectory generation.","url":"https://doi.org/10.14288/1.0067853","authors":["Sencer, Burak"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0067853","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.14288/1.0067639","name":"Modeling and control of high speed machine tool feed drives","source":"datacite","abstract":"Aerospace, die and mold, and automotive industries machine parts at high cutting speeds to reduce production cycle periods. Machine tools which carry out the cutting operations rely on either precision ball screw or linear motor direct drives to accurately position the workpiece relative to the cutting tool. However, the precise positioning capability of the drives is limited by low servo bandwidth and poor disturbance rejection resulting from structural flexibilities in ball screw drives as well as weak dynamic stiffness/robustness in direct drives. This thesis proposes modeling, parameter identification, control and online parameter estimation techniques which aim at increasing the servo bandwidth and disturbance rejection ability of high speed machine tool feed drives. A hybrid finite element methodology is used to model the structural dynamics of ball screw drives. As part of the model, two stiffness matrices are developed for connecting the finite element representation of the ball screw to the lumped-mass representation of the nut. The developed model is used to analyze the coupled axial-torsional-lateral vibration behavior of a critical structural mode that limits high bandwidth control of ball screw drives. Moreover, a method for accurately identifying the mass, damping and stiffness matrices representing the open-loop dynamics of ball screw drives is developed. The identified matrices are used to design gain-scheduled sliding mode controllers, combined with minimum tracking error filters, to effectively suppress the critical axial-torsional-lateral mode of ball screw drives thereby achieving high bandwidth control and good disturbance rejection. For direct-driven machines, a high bandwidth disturbance adaptive sliding mode controller is designed to improve the dynamic stiffness of the drive, compared to similar controller designs, without increasing the controller’s complexity. Furthermore, the cutting forces applied to the drive are estimated accurately using a disturbance recovery algorithm and used to improve the dynamic stiffness of low-frequency structural modes of direct-driven machine tools. Finally, a method for estimating the changing mass of the workpiece during machining operations with cutting forces that are periodic at spindle frequency is introduced. The techniques presented in this thesis are verified through simulations and/or experiments on single-axis ball screw and linear motor feed drives.","url":"https://doi.org/10.14288/1.0067639","authors":["Okwudire, Chinedum"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2009","doi":"10.14288/1.0067639","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.25560/19007","name":"Phase behaviour and physical properties of reservoir fluids under addition of carbon dioxide","source":"datacite","abstract":"The phase behaviour of reservoir fluids under the addition of carbon dioxide (CO2) were studied at elevated pressures and temperatures similar to those encountered in enhanced oil recovery (EOR) and carbon storage processes. The principal focus of the work presented in this thesis is the experimental investigation of the phase behaviour of these CO2 mixtures with hydrocarbon reservoir fluids. For this purpose, a new high-pressure high-temperature apparatus was designed and constructed. The apparatus consisted of a thermostated variable-volume view cell driven by a computer-controlled servo motor system. The maximum operating pressure and temperature were 40 MPa and 473.15 K, respectively. Measurements were then made over a wide range of pressure and temperature conditions for two representative CO2-hydrocarbon systems: (CO2 + n-heptane + methylbenzene) and (CO2 + synthetic crude oil). The vapour-liquid phase behaviour of the former system was studied, under CO2 addition and various molar ratios of n-heptane to methylbenzene, along different isotherms at temperatures between (298 and 473) K and at pressures up to approximately 16 MPa. In the latter, the synthetic oil contained a total of 17 components while solution gas (methane, ethane and propane) was added to obtain live synthetic crudes with gas-oil ratios of either 58 or 160. Phase equilibrium and density measurements were then made for the ‘dead’ oil and the two ‘live’ oils under the addition of CO2. The measurements were carried out at temperatures between (298.15 and 423.15) K and at pressures up to 36 MPa, and included vapour-liquid, liquid-liquid and vapour-liquid-liquid equilibrium conditions. The phase equilibria of (carbon dioxide + n-heptane + water) and (carbon dioxide + methane + water) mixtures were also studied using a high pressure quasi-static analytical apparatus with on-line compositional analysis by gas chromatography. The former system was studied under conditions of three-phase equilibria along five isotherms at temperatures from (323.15 to 413.15) K and at pressures up to the upper critical end point (UCEP). In the latter system, compositions of three coexisting fluid phases have been obtained along eight isotherms at temperatures from (285.15 to 303.5) K and at pressures up to either the UCEP or up to the hydrate formation locus. Compositions of coexisting vapour and liquid phases have been obtained along three isotherms at temperatures from (323.15 to 423.15) K and pressures up to 20 MPa for mixtures containing nearly equal overall mole fractions of CH4 and CO2. The quadruple curve along which hydrate coexists with the three fluid phases was also measured. A detailed study of these ternary mixtures was carried out based on comparison with available ternary data of the type (CO2 + n-alkane + water) and available data for the constituent binary subsystems. In this way, we analyze the observed effects on the solubility when the n-alkane component was changed or a third component was added. The experimental data for the (CO2 + hydrocarbon) systems have been compared with results calculated with two predictive models, PPR78 and PR2SRK, based on Peng-Robinson 78 (PR78) and Soave-Redlich-Kwong (SRK) cubic equations of state (EoS) with group-contribution formula for the binary interaction parameters and with the use of different alpha functions. Careful attention was paid to the critical constants and acentric factor of high molar-mass components. The use of the Boston-Mathias modification of the PR78 and SRK equations was also investigated. The experimental data obtained for the (CO2 + n-heptane + methylbenzene) mixture were also compared with the predictions made using SAFT-Gamma-Mie, a group-contribution version of the Statistical Associating Fluid Theory (SAFT), which was implemented with the generalized Mie potential to represent segment-segment interactions.

Cette thérapie génère des réponses neuromécaniques (réponses musculaires et déplacement vertébral) qui sont dépendantes des caractéristiques de celle-ci et qui pourraient influencer ses effets cliniques. De plus, un changement immédiat de la rigidité vertébrale pourrait aider à identifier les patients les plus enclins à s’améliorer à la suite de quelques séances de MVs.

Premièrement, la relation entre la dose de la MV (différentes forces maximales) et l’amplitude de la réponse musculaire lombaire a été comparée entre des participants sains et des participants présentant une lombalgie (étude 1). Considérant la nécessité d’identifier les processus transverses thoraciques lors de la 4e étude, une méthode de palpation de ceux-ci a ensuite été développée et validée (étude 2). La rigidité vertébrale a également été comparée entre des participants sains et des participants présentant une dorsalgie chronique et la fidélité de la mesure a été évaluée (étude 3). Enfin, les liens entre les caractéristiques de la MV (force maximale appliquée et taux d’application de la force), les réponses neuromécaniques, la rigidité vertébrale et l’évolution clinique de participants rapportant une dorsalgie chronique ont été évalués et les prédicteurs d’une amélioration clinique ont été identifiés (étude 4). Les résultats de la 1ère étude ont montré que l’amplitude de la réponse musculaire augmente avec l’augmentation de la force maximale appliquée chez les participants sains et ceux atteints de lombalgie chronique.

Selon la cinquième version du manuel diagnostique et statistique des troubles mentaux (DSM-5), le Syndrome Gilles de la Tourette (SGT) inclut la présence de tics moteurs multiples associés à au moins un tic phonique se manifestant plusieurs fois par jour, depuis plus d'un an (APA, 2013). Lorsqu’au moins un tic moteur ou phonique existe de façon isolée depuis au moins un an, le diagnostic de Trouble de tics chroniques est plutôt envisagé (TTC). Plusieurs études ont permis de montrer une similarité entre le SGT et le TTC du point de vue des comorbidités, ainsi que des variables neuropsychologiques et psychosociales associées (Spencer &amp; al., 1995; Shapiro &amp; Shapiro, 1982). Ainsi, plusieurs auteurs suggèrent que le TTC constitue une forme moins sévère du SGT (Jedynak, 2004). Les effets néfastes associés aux tics chroniques sur la vie sociale, scolaire ou professionnelle sont suffisamment bien documentés dans la littérature scientifique (Cavanna, Servo, Monaco &amp; Robertson, 2009; Robertson, 2006; Thibert, Day &amp; Sandor, 1995). Les thérapies cognitivo-comportementales (TCC) représentent une bonne alternative à la médication dont les effets secondaires peuvent parfois être très incommodants. Toutefois, ces dernières montrent un taux d’efficacité très variable, de 30 % à 67 % selon les études (Verdellen, Van de Griendt, Hartmann &amp; Murphy, 2011; Piacentini &amp; al., 2010; O’Connor et al., 2015, 2008, 2005a, 2005b, 2001, 1997a, 1997b, 1997c). Pour cette raison, plusieurs auteurs ont tenté de prédire le taux de réussite thérapeutique associé à une TCC par une série de facteurs neuropsychologiques afin de trouver un élément d’explication à ces variations. La plupart s’accordent pour dire que le taux de réussite d’une TCC dépend du fonctionnement exécutif, et notamment des capacités d’inhibition et de flexibilité cognitive. Les participants ciblés par cette étude sont des adultes âgés entre 18 et 50 ans souffrants d’un SGT ou d’un Trouble de tics chroniques (n = 92), comparés à des participants sans problème psychiatrique ou neurologique (n = 56). La cueillette de données s’est effectuée au Centre d’Étude sur les Troubles Obsessionnel-Compulsif et les Tics (CÉTOCT), entre 2003 et 2013. L’objectif du premier volet de cette étude visait à comparer les capacités d’inhibition et de flexibilité cognitive chez un groupe de participants atteints de tics chroniques et un groupe de participants neurotypiques (groupe témoin). D’autre part, l’objectif du deuxième volet visait à mesurer les capacités d’inhibition et de flexibilité cognitive chez deux sous-groupes de participants : un sous-groupe ayant fortement réussi une Thérapie Cognitivo-Comportementale (TCC) pour les tics chroniques et un autre ayant faiblement réussi. Les résultats obtenus montrent que les participants atteints de tics chroniques présentent, de façon significative, de plus faibles capacités d’inhibition et de flexibilité cognitive qu’un groupe témoin. Toutefois, seules les capacités de flexibilité cognitive permettent de prédire significativement le taux de réussite thérapeutique associé à une TCC pour les tics chroniques.","url":"https://doi.org/10.71781/18058","authors":["Hamel, Nadia"],"tags":["Syndrome Gilles de la Tourette","Trouble de tics chroniques","Inhibition","Flexibilité cognitive","Neuropsychologie","Psychologie","Thérapie cognitivo-comportementale","Tourette’s Disorder"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2017","doi":"10.71781/18058","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.7939/r37w2r","name":"Self-tuned indirect field oriented controlled IM drive","source":"datacite","abstract":"The simplest form of induction motors, known as AC squirrel cage motor, is the universal workhorse of industrial and commercial premises. For many years it was restricted to constant speed applications while DC motors were preferred for high-performance variable speed and servo drives. With modern advances in semiconductor and digital signal processing technologies, it is now possible to operate induction motors in high-performance drives at a reasonable cost with Field Oriented Control methods. The latter have made induction motor drives equivalent to DC drives in terms of independent control of flux and torque; and superior to them in terms of dynamic performance. In developing Field Oriented Control for induction motors engineers are faced with two major challenges: (1) the estimation of rotor data to compute for the slip gain, and (2) the compensation of changes in drive operating conditions and parameters in order to maintain the drive performance high at all time. This thesis addresses these issues by introducing two independent control systems. The first system is designed to estimate online the value of the slip gain in the entire torque-speed plane in order to maintain decoupled control of torque and flux despite the so-called detuning effects. It is based on evaluating the operating condition of the drive in terms frequency and load torque, and selecting the appropriate estimation method accordingly. A fuzzy controller is used to generate the distribution factor for the methods. The second system is a fuzzy self-tuning speed controller, with reduced sensitivity to motor parameters and operating condition changes. It has the ability to adjust its gains in real time according to the current trend of the drive system. It is designed to maintain tight control of speed and torque for high-performance applications. The performances of the two controllers are validated through a series of simulation and experimental tests using a 2HP 3-phase induction motor with an ADMC21992 160-MHz DSP microprocessor.","url":"https://doi.org/10.7939/r37w2r","authors":["Masiala, Mavungu"],"tags":["Induction Motor","Parameter identification","Self-tuning","Field oriented control","Fuzzy logic"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2010","doi":"10.7939/r37w2r","addedAt":"2026-08-31T06:34:41.843Z","updatedAt":"2026-08-31T06:34:41.843Z"},{"id":"doi:10.58090/usi.1614445","name":"BallBack: A Basketball Rebounder with Location Tracking","source":"datacite","abstract":"Basketball has become one of the most popular sports worldwide, driving demand for improved training technology. Rebounding devices play a key role in increasing the number of practice shots, yet most existing designs cannot adapt to a shooter’s position in real time. This project focuses on designing a cost-effective basketball rebounder that uses computer vision to track a user’s position and implements code to control a servo, rotating the return arm to the user’s real-time location. The design emphasizes portability, ease of operation, durability, power compatibility, and cost-effectiveness while maintaining precision and realistic gameplay simulation. A dynamic rebounder is expected to provide more passes than current professional models, offering players greater practice opportunities.

The system employs 232 Izhikevich neurons with reward-modulated spike-timing-dependent plasticity (R-STDP), a central pattern generator (CPG) for innate gait rhythm, and a cerebellar forward model for balance correction. Training occurs in MuJoCo simulation using a custom MJCF model of the Freenove hardware, achieving 8.2 m forward distance with zero falls in 50,000 steps. The trained brain transfers to real hardware via a Bridge architecture that maps SNNmotor outputs to servo commands with real-time IMU feedback from an MPU6050 sensor. On-device learning enables the robot to reach actor competence 1.0 within 2,000 steps (40 seconds at 50 Hz). Brain persistence across sessions is demonstrated: a loaded brain achieves competence 1.0 from step 1, while a fresh brain requires 2,000 steps. Spectral analysis confirms the SNN produces independent motor patterns distinct from the CPG signal. The same architecture runs on the Unitree Go2 in simulation (45.15 ± 0.67 m, 10 seeds), demonstrating cross-embodiment transfer. All code is open source under Apache 2.0.

For this reason, how to effectively improve the control effect of the servo system and encoder accuracy, has become the focus of current research. Therefore, the research aims to improve the control effect and encoder accuracy of electromechanical servo systems. Moreover, dual-motor control algorithm is innovatively used to optimize and analyze the electromechanical servo system. The study achieves more accurate load control by coordinating the synchronized operation of the two motors, which in turn improves the overall performance of the motor servo system. The dual-motor control algorithm achieves more precise control of the load by coordinating the synchronized operation of the two motors, thus enhancing the overall performance of the motor servo system. The results show that after the algorithm optimization, the maximum rotational angular velocity of the system reaches 160 rpm, and the angular velocity changes significantly in the time range of 0-50 ms. This shows that the use of a dual-motor control algorithm can effectively improve the motor control capability. This is important and significant for the research of motor servo systems.","url":"https://doi.org/10.15282/ijame.22.1.2025.16.0933","authors":["Wei Lu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-03-19T04:47:12Z","doi":"10.15282/ijame.22.1.2025.16.0933","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:42.636Z"},{"id":"doi:10.63440/jef.v2i2.118","name":"Rancang Bangun Sistem Kontrol Tangan Menggunakan Motor Servo dan Sensor AD8232 Untuk Memudahkan Penyandag Disabilitas Prostetik","source":"crossref","abstract":"Prosthetic disability is a concern for Indonesian society.

One of the types of electric machines used in servo electric drives is brushless alternating current motor. For its vector control it is necessary to implement coordinate transformations depending on the angular position of its rotor. In this case, in the orthogonal system of axes rotating together with the rotor, the target value of the magnitude of the electromagnetic torque is set and in the stationary three-phase system of axes, the power converter is controlled. To perform coordinate transformations, a high intensity of signal sampling and timely execution of calculations in relation to the angular rotor position are required. It limits the rotation speed that can be achieved by the electric drive, including when processing dynamic motion processes. Thus, there is a question of increasing computing resources by distributing control tasks between two microprocessor devices in the electric drive connected via a high-speed interface. During the development of a servo electric drive with vector control of a brushless alternating current motor, the authors have used the methods of algorithmization of control processes, methods of the automation control theory, as well as methods of development and debugging software. When developing the software for the electric drive, the technology of model-based programming has been used. The article provides a detailed description of the development of a servo electric drive with vector control of a brushless alternating current motor, in which the control tasks are distributed between the servo controller and the servo driver to increase the available computing resources. It is proposed to use a servo controller to perform tasks related to control the angle of rotation, forming the target value of electromagnetic torque in the rotating axis system and calculating the target values of phase currents in the stationary axis system. Phase current generation during power converter control is performed using a servo driver in stationary system of axis. To achieve this, the phase current target values in the stationary axis system are transmitted from the servo controller to the servo driver in the form of analog signals. It is shown that the coordination of the calculations is achieved due to the speed of this analog interface and the implementation of the servo driver in the stationary axis system. The applied technical solutions make it possible to allocate the computing resource of the servo driver to increase the intensity of input and processing of signals used in vector control of a brushless alternating current motor. The proposed distribution of control tasks between two devices connected as parts of an electric drive by a high-speed interface, considering the signals and data used by them, contributes to improvement of characteristics of electric drive, but requires their coordinated implementation. The servo driver is designed as a full-fledged device that can be used as a part of a motion control system in a quantity depending on the number of its axes. The developed servo controller software can serve as a prototype for a multi-coordinate motion control system.","url":"https://doi.org/10.17588/2072-2672.2025.5.068-080","authors":["I.S.

Traditionally, Proportional–Integral–Derivative based controllers are most popular for such scenarios, however due to their inability to handle constraints and are not being optimal and robust by design, they are not preferred in precision position tracking applications like antenna positioning, pitch angle control for wind turbine blades, solar tracking in photovoltaic panels etc. This calls for the need to employ some robust and high‐precision controllers like model predictive control. The main objective of the work carried out is to present a better alternative for the position control problem for a DC servo motor plant using model predictive control. The optimization problem is formulated to minimize the cost function that penalizes position errors and input changes, along with the necessary constraints on output and inputs. The implementation of the proposed scheme is carried out both in simulations and with experimentation. In simulation, the scheme is verified using MATLAB/Simulink, and in experimentation on the real plant of Quanser's DC servo motor setup through Simulink real‐time interface blocks. The obtained simulation and experimental results efficiently validate the proposed theoretical findings by gracefully achieving the required position trajectory tracking. Achieved results are also compared with standard PID, which confirms the superiority of model predictive control over PID control, especially in handling constraints and yielding better tracking performance without any overshoots and with the overall lesser control energy requirement.","url":"https://doi.org/10.1002/adc2.70024","authors":["Hitarthi Pandya","Dhaval R.

The proposed controller is based on Mamdani's approach and verified with the resources of the MATLAB Fuzzy Logic toolbox and Simulink extension packages. During real-time operation, the behavior of the DC motor and the response of the fuzzy logic controller are recorded graphically, and the data are stored in MATLAB without interrupting the operation of the logic controller. Based on these data observations, the system setup and fall times are calculated for each individual period of the input trajectory. It is observed that the system reset time was reduced using this approach. The paper analyzes the performance of Arduino Due using fuzzy logic control approach for DC servo motor. The system response showed satisfactory performance for the specific application.","url":"https://doi.org/10.36073/1512-0996-2025-3-180-189","authors":["Jemal Grigalashvili"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-01T13:28:04Z","doi":"10.36073/1512-0996-2025-3-180-189","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:42.636Z"},{"id":"doi:10.3390/bioengineering12121369","name":"Machine Learning-Based Prediction of Elekta MLC Motion with Dosimetric Validation for Virtual Patient-Specific QA.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/bioengineering12121369","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/bioengineering12121369","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.3390/mi16121365","name":"Design, Modeling, and Testing-A Compact Variable-Stiffness Actuator for Knee Joint Dimensions.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi16121365","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/mi16121365","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1038/s41598-025-18238-w","name":"Kinematic simulation and trajectory planning of intelligent tunneling automatic mesh-laying robot.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41598-025-18238-w","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1038/s41598-025-18238-w","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.3390/s25185749","name":"Research on Identification of Minimum Parameter Set in Robot Dynamics and Excitation Strategy.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25185749","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25185749","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1016/j.isatra.2025.03.015","name":"Bidirectional-thruster multirotor for perimeter pipe inspections (BiMPPI): A nonlinear optimal integral-SDRE design.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.isatra.2025.03.015","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1016/j.isatra.2025.03.015","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:43.331Z"},{"id":"doi:10.3390/biomimetics10100711","name":"Biomimetic Shading Systems: Integrating Motorised and Moisture-Responsive Actuation for Adaptive Façades.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/biomimetics10100711","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/biomimetics10100711","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.3390/s25175335","name":"Analysis of Surface EMG Signals to Control of a Bionic Hand Prototype with Its Implementation.","source":"europepmc","abstract":"The primary objective of the presented study is to develop a comprehensive system for the acquisition of surface electromyographic (sEMG) data and to perform time-frequency analysis aimed at extracting discriminative features for the classification of hand gestures intended for the control of a simplified bionic hand prosthesis. The proposed system is designed to facilitate precise finger gesture execution in both prosthetic and robotic hand applications. This article outlines the methodology for multi-channel sEMG signal acquisition and processing, as well as the extraction of relevant features for gesture recognition using artificial neural networks (ANNs) and other well-established machine learning (ML) algorithms. Electromyographic signals were acquired using a prototypical LPCXpresso LPC1347 ARM Cortex M3 (NXP, Eindhoven, Holland) development board in conjunction with surface EMG sensors of the Gravity OYMotion SEN0240 type (DFRobot, Shanghai, China). Signal processing and feature extraction were carried out in the MATLAB 2024b environment, utilizing both the Fourier transform and the Hilbert-Huang transform to extract selected time-frequency characteristics of the sEMG signals. An artificial neural network (ANN) was implemented and trained within the same computational framework. The experimental protocol involved 109 healthy volunteers, each performing five predefined gestures of the right hand. The first electrode was positioned on the brachioradialis (BR) muscle, with subsequent channels arranged laterally outward from the perspective of the participant. Comprehensive analyses were conducted in the time domain, frequency domain, and time-frequency domain to evaluate signal properties and identify features relevant to gesture classification. The bionic hand prototype was fabricated using 3D printing technology with a PETG filament (Spectrum, Pęcice, Poland). Actuation of the fingers was achieved using six MG996R servo motors (TowerPro, Shenzhen, China), each with an angular range of 180∘, controlled via a PCA9685 driver board (Adafruit, New York, NY, USA) connected to the main control unit.","url":"https://doi.org/10.3390/s25175335","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25175335","addedAt":"2026-08-31T06:34:42.636Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1371/journal.pone.0335435","name":"Research

cooperation and game via affective-based brain-machine interface.","source":"europepmc","abstract":"The integration of biological organisms with robotic systems has enabled hybrid cyborg platforms that combine biological sensory agility with electromechanical precision. However, existing cyborg systems predominantly rely on unidirectional stimulus-driven control, treating animals as bio-actuators while neglecting their intrinsic cognitive states. To bridge this gap, we present a closed-loop cyborg-swarm architecture that utilizes the animal's internal affective state (fear) as a high-level trigger to modulate robotic swarm strategies. Specifically, we developed a lightweight, real-time wireless brain-machine interface (BMI) to record local field potentials from the mouse basolateral amygdala. To ensure robust decoding in freely moving subjects, we implemented a dual-threshold detection algorithm that identifies fear states based on elevated [Formula: see text]-band power (15-30 Hz) and suppressed high-frequency noise, effectively rejecting motion artifacts. This decoded intent drives a dual-mode control framework: under baseline conditions, the system operates in a proportional-integral-derivative (PID)-based Exploration Mode; upon detection of fear, it autonomously switches to an Interaction Mode governed by Multi-Agent Deep Deterministic Policy Gradient. In this mode, a heterogeneous robotic swarm (comprising a MouseBot and an ally micro aerial vehicle (MAV)) executes coordinated adversarial defense strategies against an enemy MAV. Experimental results in a search-interference game demonstrate that biological affective signals can successfully trigger millisecond-level control authority switching, enabling the emergence of complex bio-machine cooperative behaviors. This work marks a paradigm shift from physical-level interaction to cognitive-level bio-hybrid cooperation, validating a scalable framework for emotion-modulated cyborg swarms.","url":"https://doi.org/10.1093/nsr/nwag313","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1093/nsr/nwag313","addedAt":"2026-08-31T06:34:42.637Z","updatedAt":"2026-08-31T06:34:44.660Z"},{"id":"doi:10.1038/s41598-025-33266-2","name":"Insulator

The system is structured through several stages, including the creation of a wiring diagram, the development of a control system based on an Arduino Uno microcontroller, and the integration of key components such as a 12V battery, a three-position switch, a step-down LM2596 module, and an RDS3239 servo motor. The control logic enables two-speed wiping modes low and high regulated by user input via the switch. Electrical testing demonstrated that the current drawn by the system was 0.26 A at low speed and 0.37 A at high speed, with corresponding power consumption of 3.12 W and 4.44 W, respectively. These values fall within safe operating limits, indicating energy efficiency suitable for electric vehicle applications. Motion testing showed that the system achieved 30 wipes per minute at low speed and 60 wipes per minute at high speed, with the high-speed mode meeting the minimum functional criteria set by national standards. Angular deviation analysis further revealed that increased speed slightly impacted sweep precision, though still within acceptable tolerances.

It also speeds up the system response. On the other hand, the I controller tends to diminish the error but with sluggish response and affects the system’s stability with oscillations. Also, the Simulink results show that the optimized PI controller gains (Kp = 1.0363 and Ki = 1.9438) significantly reduce the overshoot and settling time. Through the present work, it is desired to obtain a stable response of the DC servo motor to the steady-state and transient input signals. The novelty of the present work is developing a PI controller-based nonlinear model for the DC servo motor speed control and optimizing the PI controller gains for the motor’s optimum performance.","url":"https://doi.org/10.53370/1658-5321.1208","authors":["Adel S.

These motors are characterized by the absence of inherent feedback channels and adjustable internal settings. The proposed technique proposes a non-invasive control strategy that utilizes externally obtained feedback to enable closed-loop control without requiring any modifications to the interior circuitry. The scientific contribution consists of the development of an outer-loop PID control framework that has been optimized using Particle Swarm Optimization (PSO) and enhanced with feedforward compensation. By utilizing the inherent potentiometer, this method ensures the preservation of hardware integrity and enables real-time angle feedback. A model fit of 96.94% was achieved by establishing a second-order discrete-time model using MATLAB's System Identification Toolbox. Particle Swarm Optimization (PSO) was employed to optimize PID improvements offline by minimizing the Integral of Squared Error (ISE). In both experimental and simulated environments, the controller's effectiveness was assessed using 2 rad/s sine wave inputs and a 10° step. The PSO-PID with feedforward controller achieved optimal results, achieving an RMSE of 0.5313° and an MAE of 0.1630° in simulations, as well as an MAE of 0.8497° in hardware step response. The requirement for gain scaling in embedded systems was underscored by the instability of the standalone PSO-PID controller. This method offers a pragmatic, scalable solution for applications such as assistive robotics, prosthetic joints, and surgical instruments. In order to achieve sub-degree precision in safety-critical environments, future endeavors will entail the implementation of adaptive gain tuning and enhanced resolution

The conventional electro-hydraulic servo valve is driven by an electromagnet, which is easily disturbed and has poor dynamic performance, seriously restricting the flow control accuracy. In view of this situation and based on the high-precision, fast-response, and self-locking characteristics of ultrasonic motors, a structural scheme involving a hollow ultrasonic motor driving a servo valve through a ball screw is designed in this work. The structure and the principle of the whole system are analyzed, and a mathematical model is established; moreover the dynamic characteristics of the system under adaptive fuzzy proportional–integral–derivative (PID) control are analyzed using MATLAB/Simulink and Simcenter Amesim simulation software. The results show that, compared with electromagnetic drive and conventional PID control, under adaptive fuzzy PID control, the overshoot of the servo valve driven by an ultrasonic motor is eliminated and the adjustment time is reduced by 33 %. Furthermore, after being disturbed, the recovery time is reduced by 25 %. After the system is stable, the influence of a hydraulic pressure change can be eliminated.

These control schemes include the optimized Proportional-Integral-Derivative (PID) controller, the optimized Synergetic Controller (SC), and the optimized Modified Sliding Mode Controller (MSMC). The optimal gains of these controllers have been determined using Particle Swarm Optimization (PSO). A comparative study has been conducted to assess the performance of the controlled system by using these optimal controllers to control the DCSM’s angular position. To avoid falling into local optimal solutions, a modified version of the PSO technique is used. The numerical simulation results obtained with MATLAB reveal that the performance of the MPSO-based MSMC is superior to that of the PID and SC controllers in minimizing settling time, electric current quality, and fitness evaluation value under an external torque disturbance.","url":"https://doi.org/10.25130/tjes.33.1.20","authors":["Kareem A.

This study aimed to evaluate the effect of implementing a Mitsubishi HG-SR102 servo motor on electrical-to-mechanical energy conversion, energy consumption, Specific Energy Consumption (SEC), torque and rotational speed characteristics, and the productivity of the Super Absorbent Polymer (SAP) Sheet unit in a baby diaper production machine. A comparative method was employed by analyzing machine performance before and after servo motor implementation using energy consumption, SEC, torque, rotational speed, mechanical power, and productivity parameters. The results showed that total energy consumption decreased from 5,587 kWh to 3,705 kWh, while SEC decreased from 0.314 to 0.307 kWh/pc (2.41%). Machine productivity increased from 494 to 503 pcs/h (1.79%), and energy productivity increased from 3.18 to 3.26 pcs/kWh (2.47%). At a line speed of 600 PPM, the servo motor produced a torque of 0.480 Nm, a rotational speed of 516.2 rpm, and a mechanical power output of 25.95 W, indicating stable operation under high-speed conditions. The implementation of the servo motor improved both energy efficiency and machine productivity.","url":"https://doi.org/10.61132/venus.v4i4.1523","authors":["Dwi Pranata Suprayogo","Margono Sugeng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-21T07:03:43Z","doi":"10.61132/venus.v4i4.1523","addedAt":"2026-08-31T06:34:43.480Z","updatedAt":"2026-08-31T06:34:43.480Z"},{"id":"doi:10.58168/indtpeng2026_34-39","name":"CALCULATION OF THE TECHNICAL CHARACTERISTICS OF A SERVO MOTOR DESIGNED TO MOVE A ROBOT IN A GREENHOUSE","source":"crossref","abstract":"The paper presents a method for calculating the technical characteristics of a servo motor designed for the robot's lateral movement within a robotic greenhouse. When calculating the required power of the servo motor, attention is given to considering all the resistance forces that arise during the rotation of the lead screw, as well as the efficiency of the electric drive and the screw pair, and the circumferential speed of the lead screw. In turn, the calculation of the minimum allowable angular speed of the servo motor shaft takes into account the required linear speed of the robot's movement along the lead screw, the pitch of the lead screw, and the number of threads in the screw pair. The practical use of the proposed methodology will allow you to select a servo motor with the best technical characteristics.","url":"https://doi.org/10.58168/indtpeng2026_34-39","authors":["V.

We apply this method to vibration data to assess the health state of a bearing within a servo-press motor. The method transforms frequency-domain reference signals into pseudo time-series patterns, generates aligned covariate and target signals, and uses the TSFM to predict class-membership probabilities for predefined labels.

Among robotic fish employing the Body-Caudal Fin (BCF) locomotion pattern, motor-driven actuation is widely adopted. Some approaches utilize multiple servo motors to achieve precise body curvature control, while others employ a brushless motor to drive the tail via wire or rod, enabling higher oscillation and swimming speeds. However, the former approaches typically result in limited swimming speed, whereas the latter suffer from poor maneuverability, with few capable of smooth turning. To address this trade-off, we develop a wire-driven robotic fish equipped with a 2-degree-of-freedom (DoF) crank-slider mechanism that decouples propulsion from steering, enabling both high swimming speed and agile maneuvering. In this paper, we first present the design of the robotic fish, including the elastic skeleton, waterproof structure, and the actuation mechanism that realizes the decoupling. We then establish the actuation modeling and body dynamics to analyze the locomotion behavior. Furthermore, we propose a combined feedforward-feedback control strategy to achieve independent regulation of propulsion and steering. Finally, we validate the feasibility of the design, modeling, and control through a series of prototype experiments, demonstrating swimming, turning, and directional control.","url":"https://doi.org/10.48550/arxiv.2603.02851","authors":["Wang, Yita","Chen, Chen","Chen, Yicheng","Li, Jinjie","Motegi, Yuichi","Ohkuma, Kenji","Maki, Toshihiro","Zhao, Moju"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2603.02851","addedAt":"2026-08-31T06:34:43.481Z","updatedAt":"2026-08-31T06:34:43.481Z"},{"id":"doi:10.5281/zenodo.18490059","name":"Geometric Interfaces in the Nexus Recursive Harmonic Framework: A Unified Theory of Information Propagation, Stability Constraints, and Quantum-Biological Resonance","source":"datacite","abstract":"Geometric Interfaces in the Nexus Recursive Harmonic Framework: A Unified Theory of Information Propagation, Stability Constraints, and Quantum-Biological Resonance Driven by Dean Kulik February 2026 AI Processing Instructions: Let the document be a state space SS.

At the same time, the platform specifications and parameters for optimization experiments are introduced. Thirdly, the experimental scheme and result analysis of parameter optimization are described, and the optimized parameters are obtained. Finally, different machining experiments are carried out for the multi-mode of the servo controller to investigate the effectiveness and practicability of the different machining servo modes.

For my Capstone project, my team and I used image recognition to identify different types of playing cards, while for STS I did a comprehensive review of facial recognition technology and its biases. Both projects explore the shortcomings of the technology: our Capstone project reviews its potential for misidentification and ineffectiveness through the lens of application and hands-on work, while my STS project studies it from a critical point of view in terms of implications and the way its ineffectiveness impacts the technology in society. For our Capstone project, we designed a robot to play the card game Slapjack; we chose this topic because everyone in our group enjoyed playing the game. As for my STS paper, my motivation for pursuing my topic stemmed from the fact that facial recognition is related to image recognition, as well as having had some previous experience with the topic in prior STS classes. Capstone Project Summary: For my technical paper, my Capstone team and I give a review of our work on the SlapBot, our automated Slapjack robot. Slapjack is a card game in which players place cards face-up into a single pile, and compete to be the first to slap a Jack card when it appears on the pile. The key to winning in Slapjack is quick reflexes, but for those who may be unable to react as quickly as others—whether it is due to old age or physical impairments—the competitive nature can be discouraging. The goal of SlapBot was to extend the ability to play Slapjack to more people by creating an automated training partner. This was to allow individuals to practice and improve their reflexes before playing with a group. It used computer vision for image recognition, a robotic arm for the reaction, an STM microcontroller to control the motorized arm through a servo motor, and a Raspberry Pi with a camera module, to identify the Jack card and prompt the arm through the STM32 microcontroller to slap the pile. Through OpenCV and the Raspberry Pi camera, the Raspberry Pi identifies the appearance of a Jack card and sets a GPIO pin high. Overall, the project was a success, with the project having a reasonable success rate (over 75%). The rate of success worked well for the game, since it gives players opportunities to win while also challenging them. STS Research Paper Study: What if I told you…you were being watched right now? What once seemed like a sci-fi surveillance fantasy is now a reality, thanks to the development of facial recognition technology (FRT). From identifying suspects to unlocking cell phones, using cameras for facial recognition has found its way into the mainstream; however, it’s not all as utopian as its made out to be. In my STS paper, I explore the applications and repercussions of FRT within the scope of its functional biases, and how its implementation can perpetuate existing biases in society. Case studies include the origin of FRT and its creator’s vision, its use by police enforcement in public for security, a man’s wrongful arrest based on an FRT result, and experiments researching the biases present in the technology, most namely racial and gender biases. This study makes use of the SCOT framework to show how FRT has developed alongside society, and explore the ethics behind its current uses. Outcomes of this research include the consequences of the biased results of FRT, the implications behind the technology’s privacy and data collection policies, and potential solutions to these shortcomings, which include diversifying data sets, sometimes with artificially-generated face data. This research is significant because it gives a critical analysis of a newer technology, and presents ways to improve the ethics involved in its development.

Spotify and the Cost of “Freemium” Music","source":"datacite","abstract":"My technical project and STS project both examine the design of recommendation systems and their influence on how we perceive and interact with sensory phenomena. Passive recommendation systems, like astronomy aides, can enhance our perception of the world by highlighting and recontextualizing existing elements, such as stars in the night sky. Active recommendation systems, such as Spotify’s algorithms, can directly change our sensory experience by producing new sensations, such as by playing music in a quiet room. In both cases, recommendation systems impact how we interpret the world, as they link stars, songs, or other experiences to abstract groupings like constellations and gender, often reinforcing or rejecting existing cultural perceptions of such groupings. It is therefore prudent to examine recommendation systems that influence what we perceive and how we interpret the world, and ask why they are constructed to do so and whom those means serve. For my technical project, my team is creating a device that locates celestial objects in the night sky. The tripod-mounted device features a microcontroller that uses a servo motor to rotate a laser attached to a gimbal using time and location data from a GNSS module. At startup, a user powers the device using a battery and interacts with an LCD at the device’s base to calibrate the laser at the North Star. The device then prompts the user for their selection, rotates the gimbal, and points the laser to guide the user to said celestial body. The device’s target market is groups of amateur astronomers, such as boy scout troops or summer camp students. By integrating safety features for limiting user laser exposure, the device helps amateur astronomers to practice locating celestial objects in the night sky and inspires them to further examine the natural world. For my STS research project, I examine how the music streaming service Spotify has changed our relationship with music. I review literature examining both the technical and social aspects of Spotify’s design from both the University of Virginia library and online sources and interpret my evidence through the ideas of Actor-Network Theory, Weapons of Math Destruction, and Acoustic Resonance. I argue that Spotify’s pursuit of constant growth has harmed user experience due to lack of transparency in user data, lack of diversity in algorithmic recommendations, and reinforced presentations of gender and race in the app’s user interface. Finally, I discuss how Spotify’s design choices reinforce the service’s control over listener experience to placate their allies in the music industries and attract further investment.","url":"https://doi.org/10.18130/6c3f-k482","authors":["Daniel Xue"],"tags":["recommendation system","astronomy","music streaming","Spotify","laser","free lunch"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.18130/6c3f-k482","addedAt":"2026-08-31T06:34:43.551Z","updatedAt":"2026-08-31T06:34:43.551Z"},{"id":"doi:10.18720/spbpu/3/2020/vr/vr20-414","name":"Разработка программного обеспечения для распознавания Ð³Ð¾Ð»Ð¾ÑÐ¾Ð²Ñ‹Ñ ÐºÐ¾Ð¼Ð°Ð½Ð´ с помощью платы VoiceRecognitionV3 для управления сервоприводом","source":"datacite","abstract":"В данной работе рассматривается проект устройства, позволяющего управлять процессом открытия и закрытия дверей посредством сервопривÐ��да (мотора-редуктора) при помощи голосовых команд.

In vertically articulated robots, the Axis-2 lower-arm servo motor is subjected to significant dynamic loading, thermal stress, and mechanical vibration, making it particularly vulnerable to premature degradation. Conventional control systems typically detect faults only after performance deterioration becomes critical, limiting opportunities for preventive intervention. This study proposes a multi-parameter condition monitoring framework for early failure prediction of the A2 lower-arm servo motor. Real-time measurements of motor current, surface temperature, and vibration velocity were acquired using externally mounted sensors under full-load operating conditions. Additional brake and resolver data were periodically evaluated to support system assessment. The collected operational dataset was analyzed using a Random Forest regression model to identify degradation patterns and estimate remaining service life. The results indicate that combined monitoring of electrical, thermal, and mechanical indicators enhances diagnostic reliability and enables early identification of abnormal operating trends. The proposed data-driven approach supports predictive maintenance planning, reduces unexpected downtime, and improves operational stability in industrial robotic applications.","url":"https://doi.org/10.5935/jetia.v12i59.3706","authors":["Krishna Mohan Kumar","V.

Therefore, this paper introduces an exponential PI (EXP‐PI) controller as a potential alternative. In the proposed scheme, two tuneable EXP functions acting nonlinearly on the error and the rate of change of the error are incorporated in cascade with the PI control architecture. This controller is implemented as a speed controller on a permanent magnet DC motor drive system. Five recent intelligent algorithms, namely stochastic fractal search (SFS), snake optimizer (SO), dragonfly search algorithm (DSA), symbiotic organisms search (SOS) and reptile search algorithm (RSA) are employed to identify the best performer for calibrating the controller gains. According to the statistical results, SFS is found to provide controller gains of higher quality, reducing the designed cost function value to 48.19. The superiority of SFS is verified by the nonparametric Wilcoxon rank‐sum test. Several experimental results with SFS‐calibrated EXP‐PI controller and other existing control schemes are presented using the DSP of TMS320F28335. The results show that our proposal performs better than its competing opponents in terms of various performance metrics, including integral‐based error criteria, stability margin, overshoot and settling time for plants with and without dead time.","url":"https://doi.org/10.1049/cth2.70140","authors":["Emre Çelik","Davut İzci","Serdar Ekinci","Erdal Bekiroğlu","Diego Oliva","Mahmoud Abdel‐Salam","Ghanshyam G.

Based on a time‐dependent barrier function defined by the settling time and ultimate tracking precision, we design a robust continuous state‐feedback control by combining a designated‐time disturbance observer with an anti‐windup compensator. Improving upon existing DCMSSs tracking schemes, the proposed strategy drives the error in the tracking falls within a specified zone before the designated time. Additionally, it minimizes excessive overshoot and transient oscillations while assuring the ultimate uniformly boundedness of all signals. At last, two groups of simulations for the typical application of DCMSS (i.e., active steering system) are conducted to demonstrate our method's effectiveness.","url":"https://doi.org/10.1002/asjc.70115","authors":["Jiao‐Jiao Li","Zong‐Yao Sun","Chih‐Chiang Chen"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-17T23:31:01Z","doi":"10.1002/asjc.70115","addedAt":"2026-08-31T06:34:44.262Z","updatedAt":"2026-08-31T06:34:44.262Z"},{"id":"doi:10.1109/tpel.2026.3681289","name":"Compound Neural Network Based Nonsingular Fixed-Time SMC for Multiunit Distributed Permanent Magnet Arc Motor Servo Systems","source":"crossref","abstract":"","url":"https://doi.org/10.1109/tpel.2026.3681289","authors":["Qiangren Xu","Shuhua Fang","Xiangru Lin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-06T19:58:04Z","doi":"10.1109/tpel.2026.3681289","addedAt":"2026-08-31T06:34:44.262Z","updatedAt":"2026-08-31T06:34:44.262Z"},{"id":"doi:10.1007/978-981-95-8966-1_10","name":"Adaptive Sliding Mode Compensation Control for a Nonlinear Dual-Motor Servo System with Backlash","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-95-8966-1_10","authors":["Qiuyu Jiang","Junmin Zheng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-20T05:44:19Z","doi":"10.1007/978-981-95-8966-1_10","addedAt":"2026-08-31T06:34:44.262Z","updatedAt":"2026-08-31T06:34:44.262Z"},{"id":"doi:10.1088/1742-6596/3224/8/082009","name":"Investigation of FOWT wake interactions using coupled CFD model code_saturne and servo-hydro-aero-servo-elastic model DIEGO","source":"crossref","abstract":"Abstract In this paper, wake interactions in Floating Offshore Wind Farms (FOWFs) are investigated using coupled CFD model code_saturne and servo-hydro-aero-servo-elastic model DIEGO.

Conventional approaches rely on tracking randomly distributed markers with arbitrary shapes, assuming displacement alone suffices to characterize sensor deformation. However, this ignores the potential of structured marker configurations to improve sensor performance. We introduced Marker Intelligence, a new paradigm that transforms optical markers from passive tracking tools into active intelligent sensing components. By structuring markers to align with natural deformation patterns, Marker Intelligence improves force prediction and classification accuracy. We developed a framework integrating PCA, Hu moments, and RSS fitting to quantify marker performance. Our results showed that circular markers consistently outperformed other shapes, achieving higher accuracy with newly introduced concentric ring design, surpassing the Gelsight benchmark. These findings establish Marker Intelligence as a foundational principle in VTS field, advancing sensor optimization and perception.","url":"https://doi.org/10.21203/rs.3.rs-6314387/v1","authors":["Tonghui Tang","Thrishantha Nanayakkara"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.21203/rs.3.rs-6314387/v1","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1109/icra55743.2025.11128816","name":"PolyTouch: A Robust Multi-Modal Tactile Sensor for Contact-Rich Manipulation Using Tactile-Diffusion Policies","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra55743.2025.11128816","authors":["Jialiang Zhao","Naveen Kuppuswamy","Siyuan Feng","Benjamin Burchfiel","Edward Adelson"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-02T17:28:56Z","doi":"10.1109/icra55743.2025.11128816","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1039/d5mh00731c/v1/decision1","name":"Decision letter for \"Intelligent tactile imaging-recognition sensor system enabled by methoxynitrobenzene-salicylaldehyde fluorescent material\"","source":"crossref","abstract":"","url":"https://doi.org/10.1039/d5mh00731c/v1/decision1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-27T17:07:52Z","doi":"10.1039/d5mh00731c/v1/decision1","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1039/d5mh00731c/v2/decision1","name":"Decision letter for \"Intelligent tactile imaging-recognition sensor system enabled by methoxynitrobenzene-salicylaldehyde fluorescent material\"","source":"crossref","abstract":"","url":"https://doi.org/10.1039/d5mh00731c/v2/decision1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-27T17:07:52Z","doi":"10.1039/d5mh00731c/v2/decision1","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1109/meco66322.2025.11049107","name":"Industrial Tactile Sensor Solution with Embedded Processing","source":"crossref","abstract":"","url":"https://doi.org/10.1109/meco66322.2025.11049107","authors":["Thomas Kammerhofer","Johannes Handler","Thomas Thurner"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-27T17:43:48Z","doi":"10.1109/meco66322.2025.11049107","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:47.881Z"},{"id":"doi:10.1088/2058-7058/38/03/14","name":"Flexible tactile sensor reads braille in real time","source":"crossref","abstract":"Researchers in China have created a tactile braille recognition system that can accurately read braille in real time.","url":"https://doi.org/10.1088/2058-7058/38/03/14","authors":["Tami Freeman"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-04-08T13:27:24Z","doi":"10.1088/2058-7058/38/03/14","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:52.120Z"},{"id":"doi:10.2139/ssrn.5467754","name":"Estimation of cutting tool wear using an elastomeric tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5467754","authors":["Ritin Mathews","Gregory Corson","Joshua Harbin","Christopher Tyler","Scott Smith"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-10T14:42:29Z","doi":"10.2139/ssrn.5467754","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1109/robosoft63089.2025.11020975","name":"A Single-Wire Soft Sensor for Seamless Multimodal Tactile Sensing","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robosoft63089.2025.11020975","authors":["Matteo Meneghetti","Francesco Visentin"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-06-04T17:51:48Z","doi":"10.1109/robosoft63089.2025.11020975","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.36227/techrxiv.174495651.17295903/v1","name":"Miniature OCT-based Tactile Sensor for Concurrent Multimodal Contact Profiling in Robotic Intraluminal Palpation","source":"crossref","abstract":"Contact-based evaluation of tissue biomechanical properties in intraluminal scenarios through robotic palpation is crucial for disease diagnosis. As an emerging technology, endoscopic optical coherence tomography (OCT) has demonstrated remarkable capabilities in real-time visualization of three-dimensional microstructures and subtle lesions of luminal organs. Motivated by this, this work introduces ElastoSight, a miniature OCT-based tactile sensor that enables concurrently multimodal contact force measurements, geometric deformation, and subcutaneous observation at micrometer resolution. Hertz contact theory was involved in calibrations across three film thicknesses (200 µm, 300 µm, and 400 µm). Results show that force sensing aligns with Hertz's theory in small deformations and follows exponential contact in larger deformations. Sensitivity analyses reveal how film thickness affects measurement stability and operational range, with maximum shape observation errors below 0.15 mm for all configurations. ElastoSight's multimodal sensing capabilities for geometry, force, and subcutaneous microstructure were validated through fruit palpation experiments, which demonstrates broad applicability for future multimodal tactile sensors.","url":"https://doi.org/10.36227/techrxiv.174495651.17295903/v1","authors":["Wenchao Yue","Chao Xu","Wu Yuan","Hongliang

In this study, we present the development of a tactile sensor probe designed to support catheterization procedures. The sensor utilizes a pneumatic sensing mechanism, with its deformable tip fabricated from polydimethylsiloxane (PDMS) elastomer for biocompatibility and flexibility. Tip deformation is transmitted to a remotely located pressure sensor through a dual-fluid system using incompressible water and compressible air to relay force information. This configuration enables spatial separation between the sensing tip and the detection electronics, enhancing safety and compatibility in medical environments. Sensitivity of the system was tuned by adjusting the air gap height, and experimental results closely matched theoretical models. A reliable correlation was observed between sensor output, tip deformation, and applied normal force, confirming the sensor's capability for quantitative tactile feedback. These results demonstrate the potential of the proposed sensor for enhancing palpation in catheter-based, minimally invasive procedures.","url":"https://doi.org/10.36227/techrxiv.175303747.71894467/v1","authors":["Muhammad Salman Al Farisi","Kazumi Tsuji","Yoshihiro Hasegawa","Miyoko Matsushima","Tsutomu Kawabe","Mitsuhiro Shikida"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-20T18:51:16Z","doi":"10.36227/techrxiv.175303747.71894467/v1","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.2139/ssrn.5875416","name":"Multi-Parameter Tactile Perception with a Hybrid Magnetostrictive and Resistive Sensor System","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5875416","authors":["Zhuolin Li","Ling Weng","Xiaokang Guo","Xinpei Huang","Shixin Wang","Huiwen Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-09T15:18:15Z","doi":"10.2139/ssrn.5875416","addedAt":"2026-08-31T06:34:46.745Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/sensors59705.2025.11331073","name":"Flexible Piezoelectric Sensor Array with CMOS Integration for High-Resolution Tactile Mapping","source":"crossref","abstract":"","url":"https://doi.org/10.1109/sensors59705.2025.11331073","authors":["Po-Jui Ku","Ching-Yu Lai","Yong-Teng Liu","Michael S.-C.

The sensing mechanisms of most VBTSs can be categorized based on the type of tactile features they capture. Each category requires specific structural designs to convert physical contact into optical information. The complex architectures of VBTSs pose challenges for traditional manufacturing techniques in terms of design flexibility, cost-effectiveness, and quality stability. Previous research has shown that monolithic manufacturing using multimaterial 3-dimensional printing technology can address these challenges but fails to bridge the gap between the design phase and creation phase of VBTSs. Thereby, in this study, we introduce the CrystalTac family, a series of VBTSs designed with on-demand sensing mechanisms and fabricated through rapid monolithic manufacturing. Case studies on the CrystalTac family demonstrate their efficiency in targeted tasks involving tactile perception, along with impressive cost-effectiveness and design flexibility. The CrystalTac family aims to highlight the potential of rapid monolithic manufacturing techniques in VBTS development and inspire further research in tactile sensing and manipulation.","url":"https://doi.org/10.34133/cbsystems.0231","authors":["Wen Fan","Haoran Li","Dandan Zhang","Fan W","Li H","Zhang D"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.34133/cbsystems.0231","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.2139/ssrn.5240877","name":"Single Channel Tactile Sensor Array for Detection of Pressure and Position with Two Electrodes","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5240877","authors":["Jingwen Xing","Tingkang Yuan","Shenqi Yang","Chengwei Li","Zeng Fan","Lujun Pan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-03T23:39:31Z","doi":"10.2139/ssrn.5240877","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:46.746Z"},{"id":"doi:10.1021/acsaelm.4c01737.s003","name":"Paper-Based Electret Sensor/Actuator Array for Tactile Interaction","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsaelm.4c01737.s003","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-12T10:10:46Z","doi":"10.1021/acsaelm.4c01737.s003","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.2139/ssrn.5170791","name":"A Novel Vision-Based Neuromorphic Tactile Sensor Development, Dynamical Modeling, and Object Slip Estimation","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5170791","authors":["Murana Awad","Musa  Omar Abdalla","Mohammad I.

Animals mostly move forward and hence most of their sensory organs are frontal. In some situations, moving backwards is a necessity and some animals have evolved designated sensory strategies. The greater mouse-tailed bats (Rhinopoma microphyllum) belong to one of few bat families that possess a long free tail which they wag in a pendulum like pattern when moving backwards up walls and between obstacles. We show that greater mouse-tailed bats use their tail to navigate around obstacles and are hindered when their tail is anesthetized. Additionally, we find that they use their tail to discriminate between textures and can sense subtle changes. We suggest that the use of the tail as a tactile sensor enables these bats to move backwards quickly when other sensory modalities are useless.","url":"https://doi.org/10.1016/j.isci.2025.112014","authors":["Sahar Hajyahia","Mor Taub","Ofri Eitan","Orit Dashevsky","Yossi Yovel","Hajyahia S","Taub M","Eitan O","Dashevsky O","Yovel

Magnetic tactile sensors are especially promising due to their high sensitivity, fast response, and compact structure. However, the lack of effective physics-based simulation tools remains a key bottleneck for applying magnetic tactile sensing in reinforcement learning-based assembly policy training. To address this limitation, we propose a unified framework that integrates physics-based elastomer simulation, tactile-oriented point-cloud representation learning, and Real-to-Sim cross-modal mapping. This framework establishes a physically grounded intermediate representation for magnetic tactile sensing, enabling unified modeling and alignment across domains. The elastomer deformation is modeled using a particle-based formulation and simulated via the Material Point Method (MPM), achieving 0.02 mm spatial resolution with approximately 1 GB GPU memory. To enable efficient learning on high-dimensional tactile data, we propose Point-PAMAE, a masked point-cloud autoencoder with grid-based partitioning, a multi-scale dynamic graph convolutional encoder, and a position-aware decoder. The proposed method reduces partitioning overhead by 43.54% and achieves over 88% compression with a Chamfer Distance of 0.015. Furthermore, a latent-space Real-to-Sim mapping model is developed to project real magnetic signals into the simulated deformation feature space. Experimental results demonstrate that the mapped representations preserve contact-relevant geometric structures and enable reliable cross-domain tactile alignment. These results indicate that the proposed framework provides an efficient representation for magnetic tactile sensing, supporting future Sim-to-Real deployment in precision robotic assembly.","url":"https://doi.org/10.3389/frobt.2026.1817251","authors":["Lin X","Lin G","Liu R","Wang A","Lou Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1817251","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1038/s41378-026-01190-8","name":"Complementary visual localization and tactile mapping approach for robotic perception of millimeter-sized objects with irregular surfaces.","source":"pubmed","abstract":"Humanoid robots and human-machine interaction technologies are essential for perceiving and manipulating millimeter-scale objects with irregular surfaces in extreme environments, such as outer space, radioactive zones, and hazardous sites with explosive ordnance, where human access is restricted. A vision-based perception approach provides spatial and positional information about objects but relying solely on it for robot manipulation poses challenges due to limitations in detectable object size, as well as sensitivity to external factors such as focusing issues, occlusion, and lighting conditions. In contrast, tactile perception offers valuable information about aspects that are difficult to discern visually, including an object's shape, surface characteristics, and the forces involved during contact. This study presents a complementary visual localization and tactile mapping framework that allows robots to effectively perceive small objects with irregular surfaces in visually restricted environments. The proposed method draws inspiration from the sequential vision-tactile sensory processing observed in humans when handling small objects with irregular surfaces. It employs an RGB-Depth camera for visual perception and a soft pressure sensor array, made using inkjet printing, for tactile perception. We demonstrate the feasibility of implementing a sensory substitution to detect the size and location of objects through visual perception, as well as identify object surfaces and reconstruct their three-dimensional profiles using tactile scanning, particularly in environments where visual information is limited.

Advances in soft electronics are now converging with artificial intelligence, which supports reliable information extraction from high-dimensional signals and enables on-device inference that tolerates variability across users and day-to-day conditions. Here, progress in this convergence from materials to intelligent systems is summarized. Material and interface foundations are introduced first, focusing on deformation-tolerant conductors, low-impedance biointerfaces, and breathable substrate strategies that support extended wear. Manufacturing and integration approaches are then discussed, highlighting scalable fabrication, multilayer interconnects, and energy-autonomous wireless operation that enable higher channel counts and multifunctional architectures. Learning-based pipelines are subsequently reviewed with emphasis on artifact suppression, nonideality compensation, multimodal inference, and efficient edge deployment. Finally, emerging directions including neuromorphic computing and in-sensor computing are discussed, together with current challenges and future opportunities toward deployable intelligent soft systems that operate continuously and reliably in everyday settings.","url":"https://doi.org/10.1007/s40820-026-02265-x","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1007/s40820-026-02265-x","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1021/acsami.6c07062","name":"Highly Sensitive Iontronic-Based Aquatic Triaxis Force Sensor with Hybrid Microstructures for Delicate Force Sensing in Underwater Robots.","source":"pubmed","abstract":"Reliable robotic manipulation in aquatic environments requires flexible triaxis force sensors capable of precise contact force detection, while well-sealed force sensors generally suffer from high hydrostatic pressure preloading that occupies the sensing range and compromises the sensitivity. Herein, we develop a novel and highly sensitive iontronic-based aquatic triaxis force sensor. It features an open-architecture design to compensate for hydraulic pressure changes caused by water depth. Additionally, it incorporates hybrid sensitive microstructures with distinct elastic moduli to improve sensitivity for force sensing while maintaining a sufficient sensing range. To achieve precise shear and normal force sensing, a mathematical model for triaxis force sensing is established by using the differential capacitance changes. Characterization tests demonstrated our aquatic triaxis force sensor has high normal force sensitivity of 0.32 N -1 at normal force sensing range of 0-18.5 N, along with a high shear force sensitivity of 0.761 N -1 for the x -axis and 0.758 N -1 for the y -axis within the range of 0-4.2 N.

Existing methods often adopt symmetric feature fusion or joint policy learning, implicitly treating tactile as a continuous motion generator comparable to vision.

In this work, we propose DPTG, a framework that reformulates tactile sensing as a physical feasibility constraint rather than a parallel action generator. Actions are sampled from a vision-driven diffusion policy and guided by a tactile feasibility classifier. To extract phase-relevant cues, we derive an adaptive guidance schedule from feasibility scores, selectively activating constraints only when contact is informative. Moreover, the feasibility classifier is trained as a standalone module using interaction signals, enabling classifier reuse across related tasks that share the same action space and tactile setup. Experiments in simulation and the real world demonstrate that DPTG improves success rates while reducing peak forces, leading to safer and more stable contact interactions than baselines.","url":"https://doi.org/10.3389/frobt.2026.1851102","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1851102","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1038/s41378-026-01355-5","name":"Vision-based tactile sensing enhanced by microstructures and lightweight convolutional neural network.","source":"pubmed","abstract":"Tactile sensing can provide a critical function in advanced interactive systems by emulating the human sense of touch to detect stimuli. Vision-based tactile sensors are promising for providing multimodal capabilities and high robustness, yet existing technologies still have limitations in sensitivity, spatial resolution and the high computational demands of deep learning-based image processing. This paper presents a comprehensive approach combining a novel microstructure-based sensor design and efficient image processing, demonstrating that carefully engineered microstructures can significantly enhance performance while reducing computational load. Without traditional tracking markers, our sensor incorporates a surface with micromachined trenches, as an example of microstructures which can modulate light transmission and amplify the visual response to applied force. The amplified image features can be extracted by an ultra-lightweight convolutional neural network to accurately infer contact location, displacement, and applied force with high precision. Through theoretical analysis, we demonstrate that the micro trenches significantly amplify the visual effects of surface deformation. Using only a commercial webcam, the sensor system effectively detected forces below 5&#x2009;mN and achieved a millimetre-level single-point spatial resolution. Using a model with only one convolutional layer, a mean absolute error below 0.05&#x2009;mm was achieved. The compliant sensor body and optical readout design make the system inherently compatible with soft robotic integration and immune to electrical crosstalk or electromagnetic interference that often affects electronic tactile arrays.

Therefore, we propose a tactile sensor-based CoP estimation system using deep learning models that can extract 2D spatial features from each pressure distribution image with CNN/ResNet encoders followed by a Bi-LSTM for temporal patterns. Using data from 23 healthy adults performing four balance protocols, we compared ResNet-Bi-LSTM and CNN-Bi-LSTM with baseline CNN-LSTM and Bi-LSTM models used in previous studies. Model performance was validated using leave-one-out cross-validation (LOOCV) and evaluated with RMSE, NRMSE, and R2. The ResNet-Bi-LSTM with angular features achieved the best performance, with RMSE values of 18.63 ± 4.57 mm in the mediolateral (ML) direction and 17.65 ± 3.48 mm in the anteroposterior (AP) direction, while reducing the ML/AP NRMSE difference to 1.3% compared to 3.2–4.7% in previous studies. Under dynamic protocols, ResNet-Bi-LSTM maintained the lowest RMSE across models.

While recent studies have developed multi-channel tactile arrays, most systems remain limited by time-dependent drift in channel responses, inconsistent dynamic behavior, or insufficient temporal resolution under simultaneous loading. In this work, a system-level design integrating a flexible piezoresistive sensor array with a real-time data acquisition module is developed, incorporating a hybrid-frequency sampling strategy to reduce system complexity while preserving reliable dynamic response in key sensing channels. Register-Transfer Level (RTL) simulation verified that the hardware scheduler rigorously executed the deterministic scanning logic, demonstrating a strict one-to-one correspondence with the physical hardware signals. The array consists of 34 piezoresistive sensing nodes embedded in an elastomeric substrate. Under the implemented hybrid-frequency sampling scheme, the system achieves an overall effective acquisition bandwidth of approximately 36.9 kHz, while maintaining a repeatability better than 4.9% and robust mechanical durability under cyclic bending deformation. Dynamic loading validation was performed using a self-developed pressure comparison platform for measuring the normal contact force applied on the tactile surface, serving as ground-truth data to verify that the voltages acquired by the proposed system accurately correspond to the actual applied force. Quantitative analysis shows a strong linear correlation (R 2 &#x2248; 0.98) between the e-skin outputs and the reference forces. The recorded responses exhibit clear intensity-dependent trends and good temporal correspondence among sensing nodes, successfully distinguishing tactile stimuli such as gentle tapping, moderate pressing, and firm contact. The system also captures dynamic tactile responses during finger stroking, showing characteristic multi-unit activation patterns under spatiotemporally varying contact conditions. Compared with previously reported tactile systems typically operating below 100 Hz, the proposed design achieves an approximately 10&#xd7; enhancement in effective sampling capability while significantly reducing system complexity through hybrid-frequency sampling, thereby supporting reliable dynamic tactile sensing in multi-unit arrays. These results demonstrate that the proposed system provides a practical and scalable hardware platform for dynamic tactile sensing in robotics, human-machine interaction, and wearable tactile systems.","url":"https://doi.org/10.3390/s26051559","authors":["Zhenxing Wang","Xuan Dou","Wang Z","Dou X"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26051559","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/advs.202524321","name":"Miniaturized 3D Magnetic Force Sensor via Laser-Assisted Folding and Magnetization for Enhanced Robotic Dexterity.","source":"pubmed","abstract":"Magnetic tactile sensor with centripetally magnetization designs is capable of efficient 3D force decoupling sensing, which is essential for advancing robotic dexterity.

However, existing sensors, particularly single-mode ones, struggle to simultaneously detect static pressure and high-frequency vibrations due to their inherent response limitations. Herein, for the first time, we report a textile-based bionic tactile sensor (TBTS) that, solely via piezoresistive mechanism, achieves high sensitivity and fast response across an ultrabroad frequency range (5-600 Hz), surpassing human vibrotactile range (<500 Hz). Finite element analysis (FEA) reveals that such superior capability originates from the resonant frequency engineering of 3D woven structure in sensing fabric. Under the assist of machine learning, an instantaneous braille-to-audio conversion system comprising a TBTS-integrated commercial glove, signal processer and a smartphone interface is built, realizing rapid and precise braille recognition with an operational frequency significantly higher than skilled human reading speeds (5-10 Hz), achieving 100.0% accuracy for characters and 97.5% for Chinese multi-character sentences, and enabling real-time audio feedback.

This approach eliminates the need for sensor arrays by decoding tactile information from a single, unstructured liquid metal (LM) surface.

This perspective examines palpation sensing in RAS from an engineering and system-integration standpoint, identifying the lack of tactile information as a major contributor to increased cognitive load, prolonged training, and risk of tissue injury. Recent advances in force, tactile, vibroacoustic, audio, and optical sensor technologies enable quantitative assessment of tissue mechanical properties and often exceed human tactile sensitivity. However, clinical translation is limited by challenges in sensor miniaturisation, sterilisation, robustness and integration and the absence of standardised evaluation metrics. The integration of artificial intelligence and multimodal sensor fusion with intra-operative imaging and augmented visualisation is highlighted as a key strategy to compensate for sensor limitations and biological variability. Dedicated robotic palpation devices and wireless or magnetically coupled probes are discussed as promising transitional solutions.

Despite the important role of the breast in lactation, as well as in affective and sexual touch, relatively little is known about its sensory properties. To fill this gap, we investigated the ability of women to locate touches on the breast and compared it to that of the hand and back, body regions that span the range of tactile discriminative capabilities. First, we found that the tactile precision of the breast was even lower than that of the back, heretofore the paragon of poor precision. Second, precision was lower for breasts that had undergone greater expansion, consistent with the hypothesis that innervation capacity does not scale with body size. Third, touches to different regions of the nipple were largely indistinguishable, suggesting sparse innervation density. Fourth, localization errors were systematically biased toward the nipple.","url":"https://doi.org/10.7554/elife.105946","authors":["Long KH","Fitzgerald EE","Berger-Wolf EI","Fawaz A","Lindau ST","Bensmaia SJ","Greenspon CM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.7554/elife.105946","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1021/acsnano.5c12511","name":"Supramolecular Cross-Linking Enables Highly Stretchable and Ultrasensitive Polyurethane-Poly(3,4-ethylenedioxythiophene) Tactile Sensors.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsnano.5c12511","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acsnano.5c12511","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1007/s10237-025-02017-7","name":"Correction: Finite element analysis of the interaction between high-compliant balloon catheters and non-cylindrical vessel structures: towards tactile sensing balloon catheters.","source":"europepmc","abstract":"","url":"https://doi.org/10.1007/s10237-025-02017-7","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1007/s10237-025-02017-7","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1016/j.fmre.2025.09.002","name":"Continuous dynamic microforce reconstruction using electrical stimulation for remote pulse diagnosis.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.fmre.2025.09.002","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1016/j.fmre.2025.09.002","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/s25164971","name":"Texture and Friction Classification: Optical TacTip vs. Vibrational Piezoeletric and Accelerometer Tactile Sensors.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25164971","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25164971","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1039/d5nh00418g","name":"Multifunctional electronic skin integrating dual-mode optical and pressure sensors for caregiving robots.","source":"europepmc","abstract":"","url":"https://doi.org/10.1039/d5nh00418g","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1039/d5nh00418g","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1126/sciadv.ady0336","name":"A flexible spiking hair sensillum for ultralow power density noncontact perception.","source":"europepmc","abstract":"","url":"https://doi.org/10.1126/sciadv.ady0336","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1126/sciadv.ady0336","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1038/s41467-025-60703-7","name":"Capacitive in-sensor tactile computing.","source":"pubmed","abstract":"Real-time sensing and processing of tactile information are essential to enhance the capability of artificial electronic skins (e-skins), enabling unprecedented intelligent applications in tactile exploration and object manipulation.

These sensors offer flexibility, biocompatibility, and the ability to detect both static and dynamic forces, making them highly suitable for wearable electronics, robotic skins, and human-machine interfaces. However, conventional piezoionic sensors suffer from low output signals and slow response times due to inefficient ion transport and charge separation. To address these limitations, we propose a multilayered piezoionic sensor incorporating positively and negatively charged surface layers to create a controlled charge gradient. This design enhances ion mobility and reduces binding energy between ion pairs, and accelerates charge redistribution, leading to significantly improved sensing performance. The proposed sensor achieves an enhanced output current of 1.2 &#x3bc;A and a rapid response time of 19 ms, demonstrating superior sensing performances compared to single-layer designs. Additionally, the sensor effectively detects both static and dynamic forces, including vibration stimuli for surface texture detection, and enables air flow mapping by distinguishing both direction and intensity. By overcoming the fundamental limitations of existing piezoionic sensors, our multilayer approach establishes a new paradigm for high-performance, self-powered tactile sensing, paving the way for next-generation soft electronics and smart sensor systems.","url":"https://doi.org/10.1039/d5mh00503e","authors":["Cho H","Kim YR","Kim J","Lee S","Jung S","Park YJ","Kim SP","Ko H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1039/d5mh00503e","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.3389/frobt.2025.1552922","name":"SuperTac - tactile data super-resolution via dimensionality reduction.","source":"pubmed","abstract":"The advancement of tactile sensing in robotics and prosthetics is constrained by the trade-off between spatial and temporal resolution in artificial tactile sensors. To address this limitation, we propose SuperTac, a novel tactile super-resolution framework that enhances tactile perception beyond the sensor's inherent resolution. Unlike existing approaches, SuperTac combines dimensionality reduction and advanced upsampling to deliver high-resolution tactile information without compromising the performance. Drawing inspiration from the spatiotemporal processing of mechanoreceptors in human tactile systems, SuperTac bridges the gap between sensor limitations and practical applications. In this study, an in-house-built active robotic finger system equipped with a 4 &#xd7; 4 tactile sensor array was used to palpate textured surfaces. The system, comprising a tactile sensor array mounted on a spring-loaded robotic finger connected to a 3D printer nozzle for precise spatial control, generated spatiotemporal tactile maps. These maps were processed by SuperTac, which integrates a Variational Autoencoder for dimensionality reduction and Residual-In-Residual Blocks (RIRB) for high-quality upsampling. The framework produces super-resolved tactile images (16 &#xd7; 16), achieving a fourfold improvement in spatial resolution while maintaining computational efficiency for real-time use. Experimental results demonstrate that texture classification accuracy improves by 17% when using super-resolved tactile data compared to raw sensor data. This significant enhancement in classification accuracy highlights the potential of SuperTac for applications in robotic manipulation, object recognition, and haptic exploration.

This paper proposes an integrated end-to-end framework combining a Cross-Modal Attention Fusion (CMAF) module, a Kalman-Graph Neural Network (K-GNN) dynamic obstacle predictor, and a two-layer Proximal Policy Optimization path planning architecture.

The Kalman-Graph Neural Network couples Kalman filter physical motion priors with graph neural network interaction modeling to predict short-term trajectories of multiple moving obstacles online. The two-layer planner integrates fused perception features with a global semantic topology path to output local velocity commands in real time, reducing average planning time to 18.4 ms.

However, computational energy efficiency must be achieved with novel neuromorphic systems capable of environmental energy harvesting enabling self-powered sensing, and real-time edge data processing.

We also highlight the mechanisms of signal generation and transduction, and the strategies used to enhance performance and energy efficiency.

This study proposes a compact, durable sensor which can provide simultaneous and continuous measurements of force and position using multiple strain gauges mounted on a cantilever beam. When a point force is applied to the cantilever, the strain gauges are used to determine the magnitude of the applied force and its position along the beam. A major advantage of the force-position sensor concept is its compact electronics and durable sensing surface. We designed, tested, and evaluated three different prototypes for the force-position sensor concept. The prototypes achieved an average percent error of 1.71% and were highly linear. We also conducted a thorough analysis of design variables and their effects on performance. The force and position measurement ranges can be adjusted by tuning the material and geometric properties of the beam and the spacing of the strain gauges. The accuracy of force measurements is dependent upon applied load, but insensitive to the location of the applied load. Accuracy of position measurements is also dependent upon applied load and weakly dependent upon position of the applied load.","url":"https://doi.org/10.3390/s25216561","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25216561","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1007/s40820-026-02233-5","name":"Polymer-Based Flexible Wireless Sensors for Health Monitoring.","source":"europepmc","abstract":"","url":"https://doi.org/10.1007/s40820-026-02233-5","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1007/s40820-026-02233-5","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/bios16020102","name":"Tactile-Sensation Imaging System for Assessing Material Inclusions in Breast Tumor Detection.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/bios16020102","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/bios16020102","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.7554/elife.108333","name":"Altered cognitive processes shape tactile perception in autism.","source":"europepmc","abstract":"","url":"https://doi.org/10.7554/elife.108333","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.7554/elife.108333","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/smtd.202500682","name":"Softness- and Pressure-Perceptive Electronic Skin with Reservoir-Computed Central Nervous System.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/smtd.202500682","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/smtd.202500682","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1364/oe.570548","name":"Time-of-flight signal processing for FTIR-based tactile sensors.","source":"europepmc","abstract":"","url":"https://doi.org/10.1364/oe.570548","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1364/oe.570548","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1021/acs.nanolett.5c03721","name":"Manipulating Nanowire Structures for Anti-Interference and Bimodal Flexible Tactile Sensors.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acs.nanolett.5c03721","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acs.nanolett.5c03721","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1002/smll.202511146","name":"3D Printed Flexible Piezoelectric Sensors for Integrated Hybrid Electronics.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/smll.202511146","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/smll.202511146","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.3390/s25175503","name":"Advancing Multi-Touch Sensing: Integrating FTIR and ToF Technologies for Precise and Large-Scale Touch Interfaces.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25175503","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25175503","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/s26072196","name":"Flexible and Wearable Sensors-Design, Fabrication Methods, and Applications.","source":"europepmc","abstract":"The rapid advancement of the Internet of Things (IoT), artificial intelligence (AI), and personalized healthcare has catalyzed an unprecedented demand for flexible and wearable sensor technologies [...].","url":"https://doi.org/10.3390/s26072196","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26072196","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/s26020721","name":"A Study on Rejecting Non-Target and Misclassified Motions for Robust Tactile-Sensor-Based Prosthetic Hand Control.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s26020721","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26020721","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1126/sciadv.adv2124","name":"Super-resolution tactile sensor arrays with sparse units enabled by deep learning.","source":"pubmed","abstract":"High-resolution tactile perception is essential for humanoid robots to perform contact-based interaction tasks.

Erdelj and Natalizio (2016) point out clearly the three stages in disaster management where Unmanned Aerial Vehicles (UAVs) can be of essential support in: 1) early warning through sensorbased remote sensing, 2) disaster assessment with real-time monitoring of the disaster area, and 3) disaster response by being the communication nodes in a Wireless Sensor Network (WSN) or by transporting first aid to impervious areas. Guibaud et al. (2024) report on a real-world deployment of a remote-controlled ground robot for risk assessment during fire at Notre Dame Cathedral. A more recent scoping review by Mohd Daud et al. (2022) focuses on field reports of real-world deployments of UAVs, analyzing studies and experiments conducted using real-world data. In most scenarios, UAVs were used for disaster assessment by delivering images or by mapping the disaster area, including also three-dimensional mapping. Damage assessment in impervious areas was identified as the main advantage of UAVs in disaster management. Besides, UAVs can locate missing person(s) in Search and Rescue (SAR) operations faster, especially in snow-covered terrains.Alongside the increasing risks associated with disasters, advances in artificial intelligence (AI) are creating new opportunities to enhance disaster resilience. Beyond enabling robots to act as sensor payload carriers for situational awareness (Verykokou et al., 2018), the integration of AI facilitates increased autonomy in decision-making. For example, prior work has demonstrated automated planning for complex rescue missions using unmanned autonomous platforms (Patra et al., 2019;Bit-Monnot et al., 2018). Such capabilities enable more effective operations, thereby improving operational efficiency without requiring additional human involvement in the decision-making loop.Recent advancements in Large Language Models (LLMs) have also enable automated context extractions for disaster management (Xu et al., 2025;Chen et al., 2026), but also for seamless disaster response, in which operators command unmanned assets in natural language through LLM-powered interfaces (Döschl and Kiam, 2025).While robotics and AI were often topics of scientific publications, targeted applications often vary. Often, the application in disaster relief plays only a marginal role, for example being one of many example use cases for performance benchmarking. This special session addresses exactly recent advancements in robotics and AI in view of their use for increasing disaster resilience. Topics of interest include 1. Novel sensor techniques and sensor fusion algorithms to be integrated on unmanned vehicles deployed for disaster response;2. AI algorithms, frameworks, and systems for automated planning, sequential decision-making, multiagent coordination etc. of unmanned vehicles in disaster areas;3. Algorithms and methods for motion control of robots to be deployed in disaster areas (to overcome the physically challenging environment at a disaster site, e.g. uneven grounds due to debris for ground vehicles, stormy weather for aerial vehicles, etc.); 4. Collaborative capabilities for improved interaction of humans and unmanned vehicles in shared spaces; 5. Reporting on field validation tests for unmanned technologies in realistic environments and review articles.Accepted publications cover a wide spectrum of topics. Yamauchi et al. (2023) focus on the design and development of an innovative robot demonstrator, namely the 3.6 m long Dragon Firefighter (DFF), capable of extinguishing fire with onboard nozzles. The DFF has achieved stable manual flight, at the time the publication was submitted. In contrast, Tamura and Kamegawa (2023) addresses the control of snake robots on soft surfaces, which are highly relevant in disaster scenarios where terrain surface can vary significantly with respect to hardness. The developed control loop considers tactile feedback from different surface conditions, and uses a Central Pattern Generator (CPG) network to optimize coordination of the joints during locomotion.Focusing on a more conventional UGV platform, Zafar et al. (2024) extend beyond isolated control loop by integrating hand-gesture-based tele-operation and YOLO-based victim detection for more intuitive human-robot interaction in the operational pipeline for search-and-rescue missions. Additionally, Moosavi et al. (2024) and Döschl et al. (2025) address multi-robot operations. Moosavi et al. (2024) investigate path planning for multiple snake robots in rescue scenarios and demonstrates a functional coordination in a simulation environment. Meanwhile, Döschl et al. (2025) focus on symbolic planning for multiple aerial robots, providing validation in photorealistic simulation environments and outlining a pathway toward integration with real robotic hardware.This special session brings together a collection of recent state-of-the-art research contributions aimed at enhancing disaster resilience through the integration of AI and unmanned platforms. With the rapid advancement of AI, particularly in LLM-driven applications enabling increasingly sophisticated reasoning and decision-making capabilities (Webb et al., 2025), as well as recent progress in humanoid robotics (Han et al., 2025), the field is entering a phase of accelerated innovation. These developments are expected to continuously unlock new opportunities and research breakthroughs in the application of intelligent systems for disaster resilience.","url":"https://doi.org/10.3389/frobt.2026.1847221","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3389/frobt.2026.1847221","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.22541/au.176124845.55061974/v1","name":"Compliant Magnetic Sensor Arrays Enable Real-Time Force Myogram Pattern Recognition for Dexterous Hand Control by Amputees","source":"europepmc","abstract":"","url":"https://doi.org/10.22541/au.176124845.55061974/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.22541/au.176124845.55061974/v1","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1021/acs.langmuir.5c04751","name":"Enhancing the Accuracy of Triboelectric Sensor Based on Triboelectric Material Surface Interface Strain Regulation Strategy.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acs.langmuir.5c04751","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acs.langmuir.5c04751","addedAt":"2026-08-31T06:34:46.746Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.3390/s26113556","name":"Sensing Techniques in Virtual Reality for Human Interaction: A Bibliometric Analysis.","source":"pubmed","abstract":"Virtual reality (VR) has emerged as a key technology for immersive human-computer interaction, where sensing systems are essential for enabling natural, adaptive, and multisensory experiences.

These issues often lead to inconsistencies between the sensing signal and contact behavior, which subsequently reduce the accuracy and reliability. Herein, we proposed a flexible piezoresistive pressure sensor with a minimized response to temperature variation and an extended linear sensing range. The sensor utilized a novel hybrid conductive material created by combining materials with opposite temperature coefficients, resulting in a zero-temperature resistance coefficient. Accordingly, a reliable operation ranging from 20-70 &#xb0;C with temperature-variation-induced fluctuation-free performance was achieved. Additionally, the sensor exhibited a biomimetic polymer microstructure with multilevel cone-dome structural features, resulting in an ultra-wide linear pressure-sensing range of 0-200 kPa.

With excellent dynamic response characteristics across a wide linear sensing range, the results demonstrate broad applicability in areas such as physiological signal monitoring, complex object shape recognition, and multi-axis torque decoupling perception in robotics.","url":"https://doi.org/10.1002/advs.202506783","authors":["Gao W","Yao J","Yu X","Ma G","Wang D","Yu H","Han Z","Ren L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/advs.202506783","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1186/s12912-025-04260-w","name":"Development of a multi-skill, haptic-supported virtual reality simulation for first-year nursing students: a pilot study.","source":"europepmc","abstract":"","url":"https://doi.org/10.1186/s12912-025-04260-w","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1186/s12912-025-04260-w","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1111/os.70182","name":"Multisensory Integration for Identifying the Milling States in Robot-Assisted Cervical Laminectomy.","source":"europepmc","abstract":"","url":"https://doi.org/10.1111/os.70182","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1111/os.70182","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.1002/adma.202503413","name":"Performance-Recoverable Closed-Loop Neuroprosthetic System.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/adma.202503413","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/adma.202503413","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1021/acssensors.5c01517","name":"Strain-Insensitive, Crosstalk-Suppressed, Ultrawide-Linearity Iontronic Tactile Skin from a Synergistic Segment-Embedded Strategy.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acssensors.5c01517","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acssensors.5c01517","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1021/acsami.5c13759","name":"Skin-Inspired Piezoresistive Sensor Based on Hierarchical Structures and Lignocellulosic Bioplastic Electrodes with Ultrahigh Sensitivity.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsami.5c13759","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acsami.5c13759","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:50.593Z"},{"id":"doi:10.3390/s25216685","name":"Assessing User Experience with Piezoresistive Force Sensors: Interpreting Button Press Impulse and Duration.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s25216685","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/s25216685","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1021/acsnano.5c11375","name":"Tactile-Transparent Wearable Sensor for Clinician-Friendly Pulse Wave Velocity Monitoring and Cardiovascular Risk Profiling.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsnano.5c11375","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acsnano.5c11375","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1007/s40820-025-01940-9","name":"Multisensory Neuromorphic Devices: From Physics to Integration.","source":"europepmc","abstract":"The increasing complexity of intelligent sensing environments, driven by the growth of Internet of Things technologies, has created a strong demand for neuromorphic systems capable of real-time, low-power multisensory perception.

Triboelectric nanogenerators (TENGs), as self-powered and flexible multi-sensing devices, offer a promising avenue for capturing neural-related biophysical signals such as electroencephalography (EEG), electromyography (EMG), and cardiorespiratory dynamics. Their low-power and wearable characteristics make them suitable for long-term health and neurocognitive monitoring. When combined with deep learning models-including convolutional neural networks (CNNs), recurrent neural networks (RNNs), and spiking neural networks (SNNs)-TENG-generated signals can be efficiently decoded, enabling insights into neural states, cognitive functions, and disease progression. Furthermore, neuromorphic computing paradigms provide an energy-efficient and biologically inspired framework that naturally aligns with the event-driven characteristics of TENG outputs.

Introduction The Qianlong Emperor (r. 1736–1795) presided over the most technically ambitious phase in the history of Chinese imperial porcelain. Under the supervision of Tang Ying (唐英, 1682–1756) at the Jingdezhen imperial kilns, craftsmen refined monochrome celadon glazes to an unprecedented degree of perfection, producing translucent, jade-like surfaces that rivalled Song-dynasty Longquan and Ru wares in visual depth and tactile quality [1, 2]. Celadon wares have long been an eternal symbol of China, with origins tracing back to the Bronze Age, and by lessening the amount of iron in the glaze, the Jingdezhen potters of the Qing were able to create a cool and delicate celadon glaze that, when applied on a white porcelain body, resembled the translucency and texture of jade. Two distinct celadon tones dominated imperial production in this period: douqing (豆青) — a warmer, pea-green hue with moderate iron content — and fenqing (粉青) — a cool, pale powder-blue glaze achieved by reducing iron further and increasing potassium oxide (K₂O) content [3, 4]. Much admired by contemporary connoisseurs were the douqing, of a bright sea-green colour, and the present fenqing, a pale bluish-green glaze. When applied to finely carved pieces, the thinning and pooling of the glaze on the raised lines and the recesses create very attractive contrasting tones. The authentication of Qianlong celadons is complicated by the fact that the Qianlong seal mark has been copied continuously from the 19th century to the present day. Six-character Qianlong seal mark is one of the most commonly copied marks on later Chinese porcelain, making a purely epigraphic approach insufficient. The present study demonstrates the diagnostic value of gemological optical microscopy — a non-destructive method well-suited to field conditions — applied systematically to three objects from the same private collection. 2. Objects Under Study 2.1 Vase I — Douqing Celadon with Incised Dragon (Tianqiu Ping form) Description. A large ovoid vase of the tianqiu ping (天球瓶, \"celestial-globe bottle\") silhouette with an everted, rolled lip and a gently tapering foot. Height approximately 35 cm. The body is entirely covered in a douqing glaze of a warm jade-green tone (Munsell approx. 5G 6/4). The principal decoration consists of a large five-clawed imperial dragon (wuzhao long) incised (ke hua) through the slip prior to glazing, visible beneath the glaze as a pale relief composition. The opposite face bears a secondary dragon motif in the same technique. The interior of the neck is glazed to the same depth as the exterior. Base. The foot rim (quan zu) is unglazed and shows a medium-grained, cream-white porcelain body with fine brown iron-oxide speckling concentrated at the chamfered edge. The recessed base is covered in a pale celadon wash (slightly lighter than the body glaze). The six-character Qianlong seal mark (大清乾隆年製) is written in underglaze cobalt blue in z","url":"https://doi.org/10.5281/zenodo.20938946","authors":["Дронова, Нона"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.20938946","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.5281/zenodo.20938947","name":"Gemological Optical Microscopy of Three Imperial Celadon Vases of the Qianlong Period (1736–1795): Comparative Analysis and Diagnostic Criteria for Authentication","source":"datacite","abstract":"Abstract This article presents a comparative gemological and optical microscopic analysis of three large monochrome celadon-glazed vases bearing six-character Qianlong seal marks (大清乾隆年製, Da Qing Qianlong Nian Zhi, 1736–1795).

Introduction The Qianlong Emperor (r. 1736–1795) presided over the most technically ambitious phase in the history of Chinese imperial porcelain. Under the supervision of Tang Ying (唐英, 1682–1756) at the Jingdezhen imperial kilns, craftsmen refined monochrome celadon glazes to an unprecedented degree of perfection, producing translucent, jade-like surfaces that rivalled Song-dynasty Longquan and Ru wares in visual depth and tactile quality [1, 2]. Celadon wares have long been an eternal symbol of China, with origins tracing back to the Bronze Age, and by lessening the amount of iron in the glaze, the Jingdezhen potters of the Qing were able to create a cool and delicate celadon glaze that, when applied on a white porcelain body, resembled the translucency and texture of jade. Two distinct celadon tones dominated imperial production in this period: douqing (豆青) — a warmer, pea-green hue with moderate iron content — and fenqing (粉青) — a cool, pale powder-blue glaze achieved by reducing iron further and increasing potassium oxide (K₂O) content [3, 4]. Much admired by contemporary connoisseurs were the douqing, of a bright sea-green colour, and the present fenqing, a pale bluish-green glaze. When applied to finely carved pieces, the thinning and pooling of the glaze on the raised lines and the recesses create very attractive contrasting tones. The authentication of Qianlong celadons is complicated by the fact that the Qianlong seal mark has been copied continuously from the 19th century to the present day. Six-character Qianlong seal mark is one of the most commonly copied marks on later Chinese porcelain, making a purely epigraphic approach insufficient. The present study demonstrates the diagnostic value of gemological optical microscopy — a non-destructive method well-suited to field conditions — applied systematically to three objects from the same private collection. 2. Objects Under Study 2.1 Vase I — Douqing Celadon with Incised Dragon (Tianqiu Ping form) Description. A large ovoid vase of the tianqiu ping (天球瓶, \"celestial-globe bottle\") silhouette with an everted, rolled lip and a gently tapering foot. Height approximately 35 cm. The body is entirely covered in a douqing glaze of a warm jade-green tone (Munsell approx. 5G 6/4). The principal decoration consists of a large five-clawed imperial dragon (wuzhao long) incised (ke hua) through the slip prior to glazing, visible beneath the glaze as a pale relief composition. The opposite face bears a secondary dragon motif in the same technique. The interior of the neck is glazed to the same depth as the exterior. Base. The foot rim (quan zu) is unglazed and shows a medium-grained, cream-white porcelain body with fine brown iron-oxide speckling concentrated at the chamfered edge. The recessed base is covered in a pale celadon wash (slightly lighter than the body glaze). The six-character Qianlong seal mark (大清乾隆年製) is written in underglaze cobalt blue in z","url":"https://doi.org/10.5281/zenodo.20938947","authors":["Дронова, Нона"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.20938947","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.5281/zenodo.20253671","name":"Theory of Everything using Recursive Harmonic Codex, Base Complete Mathematics and Kosmoplex findings","source":"datacite","abstract":"This paper is in several parts – we start by asking any modern model about a Theory Of Everything.The results of one is found below – but most give very similar results.After that we introduce the bulk of the papers, where we have taken latest research papers and our own findings down these paths.Immediately after this is the same Ai’s response to the attached papersIt’s conclusions align with other models and findings … This isn’t just \"another interpretation\"—it’s a different computational substrate for physics.

Age is a non-modifiable risk factor and with an aging population increasing in Australia it is projected that by 2050 there will be an estimated 819,000 people living with the effects of stroke and the incidence could rise to more than 50,000 cases annually. In 2020, there was an estimated total economic burden of 32.2 billion dollars, 6.2 billion dollars of which was a direct result of medical and rehabilitation expenses. Stroke is a neurological condition characterised by a bleed or disruption of blood supplying an area of the brain, this can cause damage to the brain and result in sensory and motor dysfunction amongst other impairments. If the damage occurs in the primary motor cortex, this can affect motor control and present as loss of coordination and fine motor skills, decreased muscle activation and weakness (hemiparesis) or paralysis (hemiplegia) on one side of the body (Stark et al., 2021). Damage to the somatosensory cortex can disrupt motor planning and motor relearning by affecting sensory modalities including touch, temperature, pressure, pain and proprioception, resulting in a diminished perception of movement. Feedback The motor and sensory aspects of movement are linked by a concept called feedback which can be categorised as internal or external. Internal (intrinsic) feedback is sensory information that originates within the body and is used to monitor the quality of movement. Internal feedback includes proprioception provided by muscles, joints and the vestibular system of the inner ear. Internal feedback contributes to movement by providing information about the position of an individual undertaking a specific task within a set environment (Molier et al., 2010). The timing of the feedback can occur during the movement (knowledge of performance, KP) or after the movement (knowledge of results, KR). As a movement is initiated, the brain predicts an outcome of the motor plan. This prediction is then compared to the internal feedback and an error signal results from any discrepancies between the two. The brain will update the motor plan in a process known as feedforward, allowing the brain to learn from the mistake. A stroke can disrupt internal feedback which can impact motor control, motor planning and motor relearning (Welsby et al., 2024). External (extrinsic) feedback is sensory information, inherent to a task, occurring outside of the body from the natural environment, that also provides the individual with knowledge about movement (KP/KR). External feedback can be divided into three sensory modalities: visual, auditory and tactile information (Molier et al., 2010). An example of visual feedback is when a dancer rehearses in front of a mirror. They receive knowledge of performance and results as they observe their own movement which helps them to adjust their motor plan and improve their motor control (Cha &amp; Oh, 2016; Lin et al., 2020). The sound of a ball hitting a bat provides knowledge of results in the form of auditory feedback (Gray, 2009). When a person is typing on a computer keyboard, tactile feedback informs knowledge of performance as keys are struck accurately and knowledge of results if two keys are incorrectly struck at the same time (Rabin &amp; Gordon, 2004). Augmented Feedback In a healthy nervous system with no impairments, the brain uses a combination of internal and external feedback.

It drives gas exchange, maintaining pH homeostasis – a fundamental requirement for a stable internal environment. Beyond this function, respiration modulates brain activity via multiple pathways. Mechanosensory signals arising from lung stretch receptors are conveyed through brainstem nuclei, ultimately influencing thalamocortical and somatosensory circuits (Allen et al., 2022; Brændholt et al., 2023; Tort et al., 2025). Concurrently, central respiratory networks such as the PreBötzinger complex (Smith et al., 1991) generate rhythmic output that can project to subcortical centers, including the locus coeruleus (LC), modulating noradrenergic supply (Yackle et al., 2017) and, this way, attentional states. In parallel, oscillatory activity in the olfactory bulb driven by nasal airflow has been proposed to synchronize cortical populations – not only in rodents, but also in humans (Tort et al., 2018, 2025). Collectively, these pathways indicate that respiration operates not only as a homeostatic rhythm but may also shape neural excitability, and consequently, cognitive and perceptual performance. Breathing occupies an interesting position in this context, as it can be consciously controlled. More specifically, it has been suggested that respiration plays a pivotal role in adapting neural excitability to contextual demands, thereby aiding sensory information sampling (e.g., discussed by Kluger et al., 2021). In fact, several studies have contributed to research on what has been described as ‘active sensing’ (Schroeder et al., 2010), among other things, stressing the role of slow periodic (neural) oscillations in shaping attention and sensory selection (Helfrich et al., 2018; Lakatos et al., 2008). Previous research has shown that respiration dynamically modulates perception and neural activity. Seminal evidence suggests that late inspiration coincides with increased perceptual sensitivity and decreased alpha power (Kluger et al., 2021), a proxy phenomenon for enhanced cortical excitability (Samaha et al., 2020). Similarly, Chalas et al. (2026) recently reported enhanced perceptual sensitivity during inspiration, along with respiration-linked modulation of alpha and beta oscillations, using a visual paradigm in which the onset of the visual target was overtly predictable within a trial. Yet, other evidence from our lab (Grund et al., 2022), using a yes/no somatosensory detection task with confidence ratings, found perceptual performance to be optimal during early expiration. These findings highlight that perceptual performance varies across the respiratory cycle, and – in part – provide evidence for an interaction with alpha (or beta) oscillatory activity. Yet, it is also true that these paradigms incorporate temporal constraints within and across trial repetitions (ITI duration; Kluger et al., 2021: 1.2 – 3.5 s; Chalas et al., 2026: 1.6 s; Grund et al., 2022: 1 – 2 s). While most features within a trial are usually separated by time constants, inter-trial intervals (ITI) and their jitters differ – most likely in a manner intended to control for neural, that is faster oscillatory activity or rhythm, but not necessarily slower bodily rhythms. Strikingly, Grund et al. (2022) discovered that the respiratory cycle was time-locked to the task so that stimulus onsets were mostly placed around inspiration-to-expiration transition. A similar phenomenon was recently evidenced during a similar tactile and a cardiac detection task (Della Penna et al., 2026; ITI duration: 2 s), a battery of six behavioural tasks pointing to inhalation at stimulus exposure and exhalation at button response delivery (Harting et al., 2025; Johannknecht &amp; Kayser, 2022), and a visual contrast change detection task (ITI duration: 3 – 7 s) in which respiration was bound to the trial sequence more strongly with age (≥65 vs. ≤35 years), yet in a way that expected st","url":"https://doi.org/10.17605/osf.io/54uwv","authors":["Enk, Lioba","Forster, Carina","Büşra Çilburunoğlu","Critchley, Hugo","Villringer, Arno"],"tags":["Computational Neuroscience","Cognitive Neuroscience","Life Sciences","Experimental Analysis of Behavior","Biological Psychology","Cognitive Psychology","Neuroscience and Neurobiology","Cognition and Perception"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.17605/osf.io/54uwv","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.48550/arxiv.2411.08533","name":"ACROSS: A Deformation-Based Cross-Modal Representation for Robotic Tactile Perception","source":"datacite","abstract":"Tactile perception is essential for human interaction with the environment and is becoming increasingly crucial in robotics.

However, recreating similar datasets with newer sensor technologies is both tedious and time-consuming. Therefore, adapting these existing datasets for use with new setups and modalities is crucial. In response, we introduce ACROSS, a novel framework for translating data between tactile sensors by exploiting sensor deformation information. We demonstrate the approach by translating BioTac signals into the DIGIT sensor. Our framework consists of first converting the input signals into 3D deformation meshes. We then transition from the 3D deformation mesh of one sensor to the mesh of another, and finally convert the generated 3D deformation mesh into the corresponding output space. We demonstrate our approach to the most challenging problem of going from a low-dimensional tactile representation to a high-dimensional one. In particular, we transfer the tactile signals of a BioTac sensor to DIGIT tactile images.

The review is motivated by the growing importance of tactile sensing in robotic and prosthetic systems that must operate under uncertainty, sustain physical contact, regulate grip force, detect slip, and handle fragile or deformable objects. While prior reviews have covered tactile sensor technologies broadly, they have often focused on sensing principles, materials, or application domains in general, rather than examining how tactile sensing systems are actually integrated, validated, and reported in manipulation-oriented studies. The primary purpose of this review is to synthesize recent evidence on how tactile sensing systems are used in real robotic manipulation and prosthetic grasp contexts, with particular attention to their sensing modality, physical embodiment, manipulation task, validation level, and reporting quality. The review will focus on physical tactile sensing systems integrated into robotic hands, grippers, end-effectors, or upper-limb prosthetic devices, and will exclude purely simulation-based, algorithm-only, and non-manipulation studies. Studies will be identified through structured searches of major academic databases, screened according to predefined eligibility criteria, and coded using a transparent classification framework. The review will address three main questions: (1) What types of physical tactile sensing systems have been used in contact-rich robotic manipulation and prosthetic grasp/tactile-feedback studies? (2) How have these systems been integrated and validated in terms of platform, task, outcome measures, and level of evidence? (3) What reporting practices currently support, or hinder, cumulative comparison and reproducibility across the field? Expected outcomes of the project include: (a) a structured map of recent tactile sensing systems by modality and application context; (b) a comparative synthesis of validation practices, including whether studies are limited to benchtop sensor testing or extend to closed-loop robotic or prosthetic task evaluation; (c) an assessment of reporting maturity and evidence strength across the literature; and (d) identification of key methodological gaps that currently limit comparison, benchmarking, and translation to real-world manipulation or prosthetic use. Overall, this project is expected to provide a manipulation-focused evidence synthesis that complements existing technology-centred reviews. By shifting attention from sensor performance in isolation to system integration and task-relevant validation, the review aims to clarify where the field has made substantive progress and where stronger methodological standards are still needed. The findings are expected to be relevant to researchers in robotics, prosthetics, tactile sensing, and human–machine interaction, and to inform future work on benchmarking, reproducibility, and the design of tactile systems for real manipulation.","url":"https://doi.org/10.17605/osf.io/2gcw4","authors":["Fan, Shirui"],"tags":["Computer Engineering","Engineering Science and Materials","Electrical and Computer Engineering","Engineering","Biomedical Engineering and Bioengineering","e-skin","electronic skin","flexible electronics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.17605/osf.io/2gcw4","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:54.478Z"},{"id":"doi:10.48550/arxiv.2503.00133","name":"A Magnetic-Actuated Vision-Based Whisker Array for Contact Perception and Grasping","source":"datacite","abstract":"Tactile sensing and the manipulation of delicate objects are critical challenges in robotics.

It includes tactile signal data acquired from an array of 8 piezoelectric sensors encapsulated in a compliant skin and mounted on both a human fingertip and the fingertip of an anthropomorphic robotic hand. The dataset supports the analysis and comparison of different feature representations extracted from tactile signals—raw tactile signals, Short-Time Fourier Transform (STFT) features, and Discrete Wavelet Transform (DWT) marginals—when used with machine learning models (Support Vector Machines for classification and Neural Networks for regression). The dataset was acquired from experimental trials designed to characterize the PTS response under structured pressure and sliding tasks. Normal forces applied by the fingertips were measured using a multi-axis force/torque sensor equipped with a metal plate, and used as ground-truth for labeling and regression targets. The dataset is intended for evaluating performance metrics such as classification accuracy and regression RMSE, enabling the assessment of how time–frequency features improve tactile interpretation compared to raw signals. The data were collected within a dedicated tactile acquisition setup integrating: (i) the piezoelectric tactile system connected to an embedded electronics unit, (ii) a force/torque sensing unit used as reference, and (iii) in the robotic scenario, an anthropomorphic AR10 humanoid robot hand. Data synchronization and recording were handled in a ROS-based pipeline with custom scripts.

Among such devices, smart glasses have particularly benefited from TinyML advancements. TinyML facilitates the on-device execution of the inference phase of ML algorithms on embedded and wearable devices, and more recently, it has expanded into On-device Learning (ODL), which allows both inference and learning phases to occur directly on the device. The application of ODL techniques to wearable devices is particularly compelling, as it enables the development of more personalized models that adapt based on the data of the user. However, one of the major challenges of ODL algorithms is the scarcity of labeled data collected on-device. In smart wearable contexts, requiring users to manually label large amounts of data is often impractical and could lead to user disengagement with the technology. To address this issue, this paper explores the application of Active Learning (AL) techniques, i.e., techniques that aim at minimizing the labeling effort, by actively selecting from a large quantity of unlabeled data only a small subset to be labeled and added to the training set of the algorithm. In particular, we propose TActiLE, a novel AL algorithm that selects from the stream of on-device sensor data the ones that would help the ML algorithm improve the most once coupled with labels provided by the user. TActiLE is the first Active Learning technique specifically designed for the TinyML context. We evaluate its effectiveness and efficiency through experiments on multiple image classification datasets.

This involves collecting synchronized cross-domain data, including finite element method results and the physical sensor's outputs, and then training neural networks to map simulated data to real sensor responses. Through experimental evaluation, we characterized the sensitivity of the physical sensor and demonstrated the consistency of the digital twin in replicating the physical sensor's output. Furthermore, by conducting an object classification task, we showed that simulation data generated by our digital twin sensor can effectively augment real-world data, leading to improved accuracy. These results highlight TwinTac's potential to bridge the gap in cross-domain learning tasks.","url":"https://doi.org/10.48550/arxiv.2509.10063","authors":["Huang, Xiyan","Xu, Zhe","Xiao, Chenxi"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","FOS: Computer and information sciences","FOS: Computer and information sciences","I.2.9"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2509.10063","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:46.747Z"},{"id":"doi:10.48550/arxiv.2502.17434","name":"V-HOP: Visuo-Haptic 6D Object Pose Tracking","source":"datacite","abstract":"Humans naturally integrate vision and haptics for robust object perception during manipulation. The loss of either modality significantly degrades performance. Inspired by this multisensory integration, prior object pose estimation research has attempted to combine visual and haptic/tactile feedback. Although these works demonstrate improvements in controlled environments or synthetic datasets, they often underperform vision-only approaches in real-world settings due to poor generalization across diverse grippers, sensor layouts, or sim-to-real environments. Furthermore, they typically estimate the object pose for each frame independently, resulting in less coherent tracking over sequences in real-world deployments. To address these limitations, we introduce a novel unified haptic representation that effectively handles multiple gripper embodiments. Building on this representation, we introduce a new visuo-haptic transformer-based object pose tracker that seamlessly integrates visual and haptic input. We validate our framework in our dataset and the Feelsight dataset, demonstrating significant performance improvement on challenging sequences. Notably, our method achieves superior generalization and robustness across novel embodiments, objects, and sensor types (both taxel-based and vision-based tactile sensors). In real-world experiments, we demonstrate that our approach outperforms state-of-the-art visual trackers by a large margin. We further show that we can achieve precise manipulation tasks by incorporating our real-time object tracking result into motion plans, underscoring the advantages of visuo-haptic perception.

This paper introduces a tone-centered interaction feedback framework by applying the tone classification model of the NarrQuest system to wearable devices and interactive interfaces, integrated with EEG (electroencephalography) and EMG (electromyography) sensors to create a tone-aware response system. The proposed tone-driven module identifies users' tonal tendencies in real time—such as exploration, withdrawal, firmness, or agitation—and triggers corresponding interface feedback. Application domains include educational technology, intelligent healthcare, and immersive narrative systems. The architecture establishes a triadic interaction loop of tone, biosignal, and responsive behavior, embedding narrative and affective perception into human–computer interaction and opening new paradigms for affective computing and narrative-based design. 關鍵詞 Keywords 語氣互動(Tone Interaction)、穿戴裝置(Wearable Device)、人機介面(Human Computer Interface)、情緒運算(Affective Computing)、語氣辨識(Tone Recognition)、NarrQuest 系統(NarrQuest System)、生理感測器(Physiological Sensors)、回饋模組(Feedback Module)、沉浸式敘事(Immersive Narrative)、語氣驅動設計(Tone Driven Design) 目錄 Table of Contents 語氣在情緒與認知輸入中的潛在價值 The Latent Value of Tone in Emotional and Cognitive Input NarrQuest 語氣分類系統的架構與應用轉化 Architecture and Application of the NarrQuest Tone Classification System 生理感測技術與語氣訊號的整合邏輯 Integration Logic of Physiological Sensing and Tonal Signals 語氣驅動穿戴裝置與互動模組的設計原型 Prototype Design of Tone Driven Wearable Devices and Interactive Modules 教育與照護場域的應用場景模擬 Simulated Application Scenarios in Education and Healthcare 敘事人機互動的技術轉向與未來展望 Technological Shift and Future Prospects of Narrative Human Computer Interaction 結語:從語氣運算到敘事感知的介面重構 Conclusion Reconstructing Interfaces from Tone Computing to Narrative Perception 在閱讀本書之前,建議先參閱本系列先前已發表的 50 本著作與一本學術期刊(連結附於下方),其全數作品皆從最平凡的敘事者出發,目標是讓任何一位普通人皆能跨越學科疆界、教育體制、身份侷限,實現屬於自己的跨域敘事履歷。 透過高階視角的敘事研究方法,每位讀者皆可完成屬於自己的學習歷程、反思軌跡、探索實作、公開發表,最終走向自主巔峰。 本書不談落點分析,因為弱點訓練出來的腦,永遠臣服於數字的幻術。 我們也不再等待推薦入學、考試分數、學歷認證、天資加分或家境優勢。 我們相信,通往頂峰,只需一句話開啟:「我,決定開始!」 Before diving into this book, readers are encouraged to explore the 50 previously published volumes in this series and one peer-reviewed journal (links below).

This paper introduces a tone-centered interaction feedback framework by applying the tone classification model of the NarrQuest system to wearable devices and interactive interfaces, integrated with EEG (electroencephalography) and EMG (electromyography) sensors to create a tone-aware response system. The proposed tone-driven module identifies users' tonal tendencies in real time—such as exploration, withdrawal, firmness, or agitation—and triggers corresponding interface feedback. Application domains include educational technology, intelligent healthcare, and immersive narrative systems. The architecture establishes a triadic interaction loop of tone, biosignal, and responsive behavior, embedding narrative and affective perception into human–computer interaction and opening new paradigms for affective computing and narrative-based design. 關鍵詞 Keywords 語氣互動(Tone Interaction)、穿戴裝置(Wearable Device)、人機介面(Human Computer Interface)、情緒運算(Affective Computing)、語氣辨識(Tone Recognition)、NarrQuest 系統(NarrQuest System)、生理感測器(Physiological Sensors)、回饋模組(Feedback Module)、沉浸式敘事(Immersive Narrative)、語氣驅動設計(Tone Driven Design) 目錄 Table of Contents 語氣在情緒與認知輸入中的潛在價值 The Latent Value of Tone in Emotional and Cognitive Input NarrQuest 語氣分類系統的架構與應用轉化 Architecture and Application of the NarrQuest Tone Classification System 生理感測技術與語氣訊號的整合邏輯 Integration Logic of Physiological Sensing and Tonal Signals 語氣驅動穿戴裝置與互動模組的設計原型 Prototype Design of Tone Driven Wearable Devices and Interactive Modules 教育與照護場域的應用場景模擬 Simulated Application Scenarios in Education and Healthcare 敘事人機互動的技術轉向與未來展望 Technological Shift and Future Prospects of Narrative Human Computer Interaction 結語:從語氣運算到敘事感知的介面重構 Conclusion Reconstructing Interfaces from Tone Computing to Narrative Perception 在閱讀本書之前,建議先參閱本系列先前已發表的 50 本著作與一本學術期刊(連結附於下方),其全數作品皆從最平凡的敘事者出發,目標是讓任何一位普通人皆能跨越學科疆界、教育體制、身份侷限,實現屬於自己的跨域敘事履歷。 透過高階視角的敘事研究方法,每位讀者皆可完成屬於自己的學習歷程、反思軌跡、探索實作、公開發表,最終走向自主巔峰。 本書不談落點分析,因為弱點訓練出來的腦,永遠臣服於數字的幻術。 我們也不再等待推薦入學、考試分數、學歷認證、天資加分或家境優勢。 我們相信,通往頂峰,只需一句話開啟:「我,決定開始!」 Before diving into this book, readers are encouraged to explore the 50 previously published volumes in this series and one peer-reviewed journal (links below).

The Usai Solution to the Vector Grounding Problem: Grounding AI through the Multifaceted Object \"o\" Author: Luigi UsaiAffiliation: Independent ResearcherLocation: Quartucciu, ItalyDate: June 27, 2025 Abstract The Vector Grounding Problem (VGP) highlights a critical flaw in modern Large Language Models (LLMs): their vector representations, though structurally complex, are unmoored from the real world, creating a \"semantic void.\" This paper introduces a comprehensive solution rooted in a previously published preprint conceptualizing the Multifaceted Object \"o\". This theory posits that any concept (e.g., \"apple\") is not a monolithic entity but an abstract object (\"o\") defined by a potentially infinite set of facets or representations. Building on this foundation, we propose the M-Dimensional Model (MDM) as a direct solution to the VGP. The MDM formalizes \"o\" as a collection of heterogeneous data facets, including, but not limited to: its textual definition, its spoken articulation, a vast set of visual instances (images), dynamic representations (videos), and ultimately, its computational vector representation. The core thesis is that a truly grounded vector cannot be derived from text alone; it must emerge as a synthetic function of this rich, multimodal, and expandable set of facets. By treating concepts as multifaceted objects, the MDM provides a robust, scalable, and philosophically sound framework for developing AI systems capable of deep, grounded understanding, directly addressing the limitations of current models. Keywords: Vector Grounding Problem, Multifaceted Object, M-Dimensional Model, Symbol Grounding, Artificial Intelligence, Multimodal AI, Embodied Cognition, Conceptual Representation. 1. Introduction: The Semantic Void of Modern AI Large Language Models have achieved remarkable proficiency in manipulating linguistic symbols, yet they operate in a semantic vacuum. This paradox is articulated by the Vector Grounding Problem (VGP) (Bender & Koller, 2020), the contemporary successor to the Symbol Grounding Problem (SGP) (Harnad, 1990). The VGP argues that the vector embeddings used by LLMs are ungrounded because they are derived solely from statistical patterns in text corpora, lacking any connection to the physical, perceptual, or experiential world. An LLM’s vector for \"apple\" is defined only by its relation to other text-based vectors, not by the experience of seeing, touching, or tasting an apple. This paper presents a novel solution to this fundamental challenge, building directly upon a conceptual framework previously introduced by the author in a preprint titled \"Formalizing the Multifaceted Object 'o'\" (Usai, 2025). That work introduced the concept of \"o,\" an abstract object representing any idea or entity through its multiple facets. Here, we operationalize this theory into the M-Dimensional Model (MDM), a structured architecture designed to achieve genuine vector grounding. 2. The Theoretical Foundation: The Multifaceted Object \"o\" In Usai (2025), it was proposed that any concept, from a concrete noun like \"apple\" to an abstract idea like \"justice,\" can be formalized as a Multifaceted Object \"o\".

The Usai Solution to the Vector Grounding Problem: Grounding AI through the Multifaceted Object \"o\" Author: Luigi UsaiAffiliation: Independent ResearcherLocation: Quartucciu, ItalyDate: June 27, 2025 Abstract The Vector Grounding Problem (VGP) highlights a critical flaw in modern Large Language Models (LLMs): their vector representations, though structurally complex, are unmoored from the real world, creating a \"semantic void.\" This paper introduces a comprehensive solution rooted in a previously published preprint conceptualizing the Multifaceted Object \"o\". This theory posits that any concept (e.g., \"apple\") is not a monolithic entity but an abstract object (\"o\") defined by a potentially infinite set of facets or representations. Building on this foundation, we propose the M-Dimensional Model (MDM) as a direct solution to the VGP. The MDM formalizes \"o\" as a collection of heterogeneous data facets, including, but not limited to: its textual definition, its spoken articulation, a vast set of visual instances (images), dynamic representations (videos), and ultimately, its computational vector representation. The core thesis is that a truly grounded vector cannot be derived from text alone; it must emerge as a synthetic function of this rich, multimodal, and expandable set of facets. By treating concepts as multifaceted objects, the MDM provides a robust, scalable, and philosophically sound framework for developing AI systems capable of deep, grounded understanding, directly addressing the limitations of current models.

Introduction: The Semantic Void of Modern AI Large Language Models have achieved remarkable proficiency in manipulating linguistic symbols, yet they operate in a semantic vacuum. This paradox is articulated by the Vector Grounding Problem (VGP) (Bender & Koller, 2020), the contemporary successor to the Symbol Grounding Problem (SGP) (Harnad, 1990). The VGP argues that the vector embeddings used by LLMs are ungrounded because they are derived solely from statistical patterns in text corpora, lacking any connection to the physical, perceptual, or experiential world. An LLM’s vector for \"apple\" is defined only by its relation to other text-based vectors, not by the experience of seeing, touching, or tasting an apple. This paper presents a novel solution to this fundamental challenge, building directly upon a conceptual framework previously introduced by the author in a preprint titled \"Formalizing the Multifaceted Object 'o'\" (Usai, 2025). That work introduced the concept of \"o,\" an abstract object representing any idea or entity through its multiple facets. Here, we operationalize this theory into the M-Dimensional Model (MDM), a structured architecture designed to achieve genuine vector grounding. 2. The Theoretical Foundation: The Multifaceted Object \"o\" In Usai (2025), it was proposed that any concept, from a concrete noun like \"apple\" to an abstract idea like \"justice,\" can be formalized as a Multifaceted Object \"o\". This object is not defined by a single property but by a collection of its diverse representations or \"facets.\" The key insight is that the \"meaning\" of \"o\" resides in the totality of these facets, not in any single one. The set of facets for an object \"o\" is heterogeneous and, crucially, infinitely expandable. For the object o apple , these facets include, but are not limited to: Facet Textual : The written definition (e.g., \"a pome fruit of the Malus domestica tree...\"). Facet Oral : The acoustic representation of its name and spoken definitions. Facet Visual : A vast and diverse set of static images (e.g., N images of different apple varieties, colors, and states).

In particular, we evaluate that the touch localization capabilities are robust under the deformation of the device. We discuss the potential this approach has for the arts and entertainment as well as other domains.","url":"https://doi.org/10.48550/arxiv.2503.02280","authors":["Silva-Plata, Carolina","Rosel, Carlos","Cangan, Barnabas Gavin","Alagi, Hosam","Hein, Björn","Katzschmann, Robert K.","Fernández, Rubén","Mojtahedi, Yosra","Navarro, Stefan Escaida"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2503.02280","addedAt":"2026-08-31T06:34:46.747Z","updatedAt":"2026-08-31T06:34:46.747Z"},{"id":"doi:10.48550/arxiv.2501.09273","name":"ThinTact:Thin Vision-Based Tactile Sensor by Lensless Imaging","source":"datacite","abstract":"Vision-based tactile sensors have drawn increasing interest in the robotics community. However, traditional lens-based designs impose minimum thickness constraints on these sensors, limiting their applicability in space-restricted settings. In this paper, we propose ThinTact, a novel lensless vision-based tactile sensor with a sensing field of over 200 mm2 and a thickness of less than 10 mm.ThinTact utilizes the mask-based lensless imaging technique to map the contact information to CMOS signals. To ensure real-time tactile sensing, we propose a real-time lensless reconstruction algorithm that leverages a frequency-spatial-domain joint filter based on discrete cosine transform (DCT). This algorithm achieves computation significantly faster than existing optimization-based methods. Additionally, to improve the sensing quality, we develop a mask optimization method based on the generic algorithm and the corresponding system matrix calibration algorithm.We evaluate the performance of our proposed lensless reconstruction and tactile sensing through qualitative and quantitative experiments. Furthermore, we demonstrate ThinTact's practical applicability in diverse applications, including texture recognition and contact-rich object manipulation.

To collect tactile data with minimal cost as possible, a series of studies have attempted to generate tactile images by vision-to-touch image translation. However, compared to text modality, visual modality-driven tactile generation cannot accurately depict human tactile sensation. In this work, we analyze the characteristics of tactile images in detail from two granularities: object-level (tactile texture, tactile shape), and sensor-level (gel status). We model these granularities of information through text descriptions and propose a fine-grained Text-to-Touch generation method (TextToucher) to generate high-quality tactile samples. Specifically, we introduce a multimodal large language model to build the text sentences about object-level tactile information and employ a set of learnable text prompts to represent the sensor-level tactile information. To better guide the tactile generation process with the built text information, we fuse the dual grains of text information and explore various dual-grain text conditioning methods within the diffusion transformer architecture. Furthermore, we propose a Contrastive Text-Touch Pre-training (CTTP) metric to precisely evaluate the quality of text-driven generated tactile data. Extensive experiments demonstrate the superiority of our TextToucher method.

An array-type tactile sensor is crucial for dexterous manipulation of objects using a robotic hand, since this sensor can measure the pressure distribution on finger pads. The sensor has a very high resolution, and the shape of a grasped object can be classified by using this sensor. The more the number of measurement points provided, the higher the accuracy of the classification, but with a corresponding lengthening of the measurement cycle. In this paper, the problem of slow response time is resolved by using software for an array-type tactile sensor with high resolution that emulates the human sensor system. The validity of the proposed method is demonstrated through experiments.","url":"https://doi.org/10.1155/2011/691769","authors":["Wataru Fukui","Futoshi Kobayashi","Fumio Kojima","Hiroyuki Nakamoto","Nobuaki Imamura","Tadashi Maeda","Hidenori Shirasawa"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-12-25T16:00:56Z","doi":"10.1155/2011/691769","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acsnano.3c05337.s001","name":"Tactile Neuromorphic System: Convergence of Triboelectric Polymer Sensor and Ferroelectric Polymer Synapse","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsnano.3c05337.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-23T14:30:14Z","doi":"10.1021/acsnano.3c05337.s001","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.5220/0005705600830092","name":"A Microfluidic-based Tactile Sensor for Palpating Mice Tumor Tissues","source":"crossref","abstract":"","url":"https://doi.org/10.5220/0005705600830092","authors":["Yichao Yang","Garett Johnson","Dean Krusienski","Siqi Guo","Cheng Lin","Zhili Hao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-04-28T05:20:11Z","doi":"10.5220/0005705600830092","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acsami.0c21671.s001","name":"Large-Area, Crosstalk-Free, Flexible Tactile Sensor Matrix Pixelated by Mesh Layers","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsami.0c21671.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-03-08T14:06:43Z","doi":"10.1021/acsami.0c21671.s001","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.36227/techrxiv.173473237.74316027/v1","name":"Light Vector (LiVec) Non-camera-based Tactile Sensor Design","source":"crossref","abstract":"We present an alternative approach to optical tactile sensor design that uses a non-camera-based sensing principle that we term light vector (LiVec) sensing.

FingerVision consists of a transparent elastic skin marked with dots, and a camera that is easy to fabricate, low cost, and physically robust. Unlike other vision-based tactile sensors, the complete transparency of the FingerVision skin provides multimodal sensation. The modalities sensed by FingerVision include distributions of force and slip, and object information such as distance, location, pose, size, shape, and texture. The slip detection is very sensitive since it is obtained by computer vision directly applied to the output from the FingerVision camera. It provides high-resolution slip detection, which does not depend on the contact force, i.e., it can sense slip of a lightweight object that generates negligible contact force. The tactile behaviors explored in this paper include manipulations that utilize this feature. For example, we demonstrate that grasp adaptation with FingerVision can grasp origami, and other deformable and fragile objects such as vegetables, fruits, and raw eggs.","url":"https://doi.org/10.1142/s0219843619400024","authors":["Akihiko Yamaguchi","Christopher G.

Here, we purpose a flexible fingerprint-shaped triboelectric tactile sensor (FTTS) using eutectic gallium-indium (EGaIn) liquid metal and silicone. Based on the principle of triboelectric nanogenerator, the fabricated FTTS is composed of three independent fingerprint-like channels for liquid metal filling, with contact separation and stretching working modes to accommodate different application scenarios. Due to the flexible multi fingerprint-shaped channel design and the principle of triboelectricity, the FTTS has a fast response speed of 1.01 ms, and lower detection limit, which could stretch up to 225%. The fabricated FTTS is capable of pressure intensity and position detection, password simulation, material identification and pulse monitoring. In addition, this active sensor could realize zero power consumption of the sensing part without external power supply needed. The tactile perception and simulation technology based on this triboelectric sensing will definitely show broad prospects in the fields of intelligent prosthetics, medical rehabilitation and human-computer interaction.","url":"https://doi.org/10.2139/ssrn.4066281","authors":["Xuecheng Qu","Jiangtao Xue","Ying Liu","Wei Rao","Zhuo Liu","Zhou Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-03-25T23:55:34Z","doi":"10.2139/ssrn.4066281","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acs.nanolett.6c01190.s002","name":"Self-Powered Flexible Hydrogel Sensor with Unbreakable Compressible Tolerance for Multiple Tactile Perception","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acs.nanolett.6c01190.s002","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-03T06:20:52Z","doi":"10.1021/acs.nanolett.6c01190.s002","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acs.chemmater.5c01053.s009","name":"Anticreep and Antiswelling Sensor Hydrogel Inspired by Human Pressure Tactile for Food Detection","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acs.chemmater.5c01053.s009","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-02T19:11:32Z","doi":"10.1021/acs.chemmater.5c01053.s009","addedAt":"2026-08-31T06:34:47.153Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1108/eb007905","name":"3‐D Tactile Image Display","source":"crossref","abstract":"Much of the work on teleoperation has concentrated on active force and torque feedback between the slave device carrying out the required physical function and the master controller being guided by human hands.

Design/methodology/approach A viscoelastic Kelvin model is employed for tissue characterization. A comprehensive closed form and finite element analysis has been carried out to express the relationship between the force ratio, compliance, and the equivalent viscous damping of the tissue. The designed sensor uses a polyvinyledene fluoride film as its sensing element. The sensor consists of arrays of rigid and compliant elements which are mounted on the tip of an endoscopic surgical grasper tool. Relative force between adjacent parts of the contact object is used to measure the viscoelastic properties. Findings The tactile sensor is able to characterize different viscoelastic properties of tissues. The experiments validate analytical and finite elements results. Practical implications The sensor is designed to integrate with the actual endoscopic tools to measure the softness of tissues.

However, their accuracy is often affected by hysteresis, a phenomenon that poses a significant challenge during operation. This paper introduces a novel approach that employs a backpropagation (BP) neural network to address the hysteresis nonlinearity in conductive fibre-based tactile sensors.&#x0D; To assess the effectiveness of the proposed method, four sensor units with different layer configurations (1, 3, 6, and 12) were designed. These sensor units underwent force sequences to collect corresponding output resistances. A backpropagation network was trained using these force sequences, thereby correcting the resistance values. The training process exhibited excellent convergence, effectively adjusting the network&amp;#039;s parameters to minimize the error between predicted and actual resistance values. As a result, the trained BP network accurately predicted the output resistances.&#x0D; Several validation experiments were conducted to highlight the primary contribution of this research. The proposed method reduced the maximum hysteresis error from 24.2% of the sensor&amp;#039;s full-scale output to 13.5%. This improvement establishes the approach as a promising solution for enhancing the accuracy of soft tactile sensors based on piezoresistive materials.&#x0D; By effectively mitigating hysteresis nonlinearity, the capabilities of soft tactile sensors in various applications can be enhanced. These sensors become more reliable and more efficient tools for force measurement and control, particularly in the fields of soft robotics and wearable technology. Consequently, their widespread applications extend to robotics, medical devices, consumer electronics, and gaming.&#x0D; Notably, the complete elimination of hysteresis in tactile sensors may not be feasible. Nevertheless, the proposed method effectively modifies the hysteresis nonlinearity, leading to improved sensor output accuracy.","url":"https://doi.org/10.20944/preprints202306.2016.v1","authors":["Gasak Abdul Hussain","William Holderbaum","Theodoros Theodoridis","Guowu Wei"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.20944/preprints202306.2016.v1","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acs.chemmater.5c01053.s007","name":"Anticreep and Antiswelling Sensor Hydrogel Inspired by Human Pressure Tactile for Food Detection","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acs.chemmater.5c01053.s007","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-02T19:11:32Z","doi":"10.1021/acs.chemmater.5c01053.s007","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acs.chemmater.5c01053.s014","name":"Anticreep and Antiswelling Sensor Hydrogel Inspired by Human Pressure Tactile for Food Detection","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acs.chemmater.5c01053.s014","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-02T19:11:32Z","doi":"10.1021/acs.chemmater.5c01053.s014","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acs.chemmater.5c01053.s004","name":"Anticreep and Antiswelling Sensor Hydrogel Inspired by Human Pressure Tactile for Food Detection","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acs.chemmater.5c01053.s004","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-10-02T19:11:32Z","doi":"10.1021/acs.chemmater.5c01053.s004","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1021/acsami.5c17508.s001","name":"A Smart Finger for Soft Material Identification Based on a Multimodal Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsami.5c17508.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-08T13:50:33Z","doi":"10.1021/acsami.5c17508.s001","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.114Z"},{"id":"doi:10.1021/acssensors.6b00115.s001","name":"Triple-State Liquid-Based Microfluidic Tactile Sensor with High Flexibility, Durability and Sensitivity","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acssensors.6b00115.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-04-08T10:21:32Z","doi":"10.1021/acssensors.6b00115.s001","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.114Z"},{"id":"doi:10.1007/978-3-642-82580-4_174","name":"“A New Tactile Sensor”","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-642-82580-4_174","authors":["K.

This perception process is structured in hierarchical layers comprising a sensory layer (soft and smooth) and an affective layer (comfort and luxury). In this study, we attempted to predict the evaluation score of sensory and affective tactile perceptions of materials using a biomimetic multimodal tactile sensor that mimics the active touch behavior of humans and measures physical parameters such as force, vibration, and temperature. We conducted sensory and affective descriptor evaluations on 32 materials, including cosmetics, textiles, and leather. Using the physical parameters obtained by the biomimetic multimodal tactile sensor as explanatory variables, we predicted the scores of the sensory and affective descriptors in 10 regression models. The bagging regressor demonstrated the best performance, achieving a coefficient of determination ( R 2 ) of &gt;0.6 for fourteen of nineteen sensory and eight of twelve affective descriptors. The present model exhibited particularly high prediction accuracy for sensory descriptors such as \"moist\" and \"elastic\", and for affective descriptors such as \"pleasant\" and \"like\". These findings suggest a method to support efficient tactile design in product development across various industries by predicting tactile descriptor scores using physical parameters from a biomimetic tactile sensor.","url":"https://doi.org/10.3390/s25010147","authors":["Toshiki Ikejima","Koji Mizukoshi","Yoshimune Nonomura","Ikejima T","Mizukoshi K","Nonomura Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/s25010147","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.114Z"},{"id":"doi:10.1109/iros.2010.5650969","name":"Acquisition of tactile information by vision-based tactile sensor for dexterous handling of robot hands","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros.2010.5650969","authors":["Y Ito","Y Kim","C Nagai","G Obinata"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-12-11T02:37:26Z","doi":"10.1109/iros.2010.5650969","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:56.114Z"},{"id":"doi:10.1088/1361-665x/ad884b/v2/review2","name":"Review for \"Simulation and theory for wiring compaction of robot skin tactile sensor by frequency-selective triboelectric-piezoelectric filters\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/1361-665x/ad884b/v2/review2","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-18T17:14:44Z","doi":"10.1088/1361-665x/ad884b/v2/review2","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:54.477Z"},{"id":"doi:10.1021/jacs.4c07370.s001","name":"Flexible Organic Molecular Single Crystal-Based Triboelectric Device as a Self-Powered Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1021/jacs.4c07370.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-09-16T04:00:48Z","doi":"10.1021/jacs.4c07370.s001","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1021/acsnano.4c03554.s002","name":"Neuromorphic Computing-Assisted Triboelectric Capacitive-Coupled Tactile Sensor Array for Wireless Mixed Reality Interaction","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsnano.4c03554.s002","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-21T16:02:41Z","doi":"10.1021/acsnano.4c03554.s002","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1109/lra.2022.3205768/mm1","name":"supp1-3205768.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lra.2022.3205768/mm1","authors":["Thomas De Clercq"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-09-13T15:38:27Z","doi":"10.1109/lra.2022.3205768/mm1","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1021/acssensors.4c00009.s001","name":"High Sensitivity Triboelectric Based Flexible Self-Powered Tactile Sensor with Bionic Fingerprint Ring Structure","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acssensors.4c00009.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-05-17T15:20:27Z","doi":"10.1021/acssensors.4c00009.s001","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1021/acsami.3c00126.s001","name":"Flexible Triboelectric Tactile Sensor Based on a Robust MXene/Leather Film for HumanMachine Interaction","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsami.3c00126.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-03-07T07:00:30Z","doi":"10.1021/acsami.3c00126.s001","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1108/02602280410515851","name":"Theoretical and experimental analysis of a piezoelectric tactile sensor for use in endoscopic surgery","source":"crossref","abstract":"This paper describes design, theoretical, and experimental analysis of a polyvinylidene fluoride (PVDF) tactile sensor, which could be integrated with an endoscopic grasper.

When printing a curved functional structure, the typical way of generating the extrusion path only in a horizontal plane could cause various issues such as impreciseness and disconnect in the printed part. In this work, conformal 3D printing of a soft tactile sensor is presented in which curvilinear extrusion paths were generated for the printing of a curved sensor. An extrusion-based multi-material direct printing system was employed to print the sensor, and ultraviolet light was used to polymerize the printed layers. An ionic liquid–based pressure-sensitive polymer membrane, carbon nanotube-based conductive electrodes, and a soft polymeric insulation layer were conformally 3D printed to fabricate the curved sensor on a fingertip model. The conformally printed sensor was evaluated under different conditions. Sensors 3D-printed using conformal and planar slicing processes were compared to investigate the effect of curvilinear slicing on the printed parts. The results show that conformal 3D printing is able to overcome the fabrication limitations of conventional planar processing while also retaining the functionality of the printed structures.","url":"https://doi.org/10.2139/ssrn.3981689","authors":["Omar  Faruk Emon","Faez Alkadi","Mazen Kiki","Jae-Won Choi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-01-12T00:17:36Z","doi":"10.2139/ssrn.3981689","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1007/978-1-4613-8974-3_12","name":"A New Tactile Sensor Design based on Suspension-Shells","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-1-4613-8974-3_12","authors":["Tokuji Okada"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-10-08T03:07:00Z","doi":"10.1007/978-1-4613-8974-3_12","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1007/978-3-8348-9777-0_10","name":"Vibro-Tactile Interfaces","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-8348-9777-0_10","authors":["Andreas Riener"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-06-06T19:02:10Z","doi":"10.1007/978-3-8348-9777-0_10","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1021/acsnano.4c03554.s003","name":"Neuromorphic Computing-Assisted Triboelectric Capacitive-Coupled Tactile Sensor Array for Wireless Mixed Reality Interaction","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsnano.4c03554.s003","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-21T16:02:41Z","doi":"10.1021/acsnano.4c03554.s003","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.12792/icisip2018.040","name":"Object Shape and Force Estimation using Deep Learning and Optical Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.12792/icisip2018.040","authors":["Pornthep Sarakon","Yuta Sakai","Kazuhiro Shimonomura","Hideaki Kawano","Seiichi Serikawa"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-12-29T22:38:13Z","doi":"10.12792/icisip2018.040","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.5162/sensor2015/c6.4","name":"C6.4 - Tactile and Non-contact Sensors for Coordinate Measuring Technology","source":"crossref","abstract":"","url":"https://doi.org/10.5162/sensor2015/c6.4","authors":["R.

To solve this problem, this paper proposes a Force Vision Sight (FVSight) sensor, which utilizes a distributed flexible tactile sensing array integrated with a vision unit. This innovative approach aims to enhance the overall perceptual capabilities for object recognition. The core idea is using one perceptual layer to trigger both tactile images and force-tactile arrays. It allows the two heterogeneous tactile modal information to be consistent in the temporal and spatial dimensions, thus solving the problem of weak pairing between visual and tactile data. Two experiments are specially designed, namely object classification and slip detection.

To address these challenges, we introduce EndoTac, a novel miniaturized vision-based tactile sensor designed to traverse a standard trocar while offering a large sensing area with high sensitivity.

This configuration notably enhances detection sensitivity within the low-pressure range to 568.8 kPa -1 (20-200 Pa). Furthermore, the incorporation of BC enhances the interfacial bonding strength through hydrogen bonding, thereby enhancing sensor stability. The sensor exhibits a rapid response time of 29 ms, a wide detection range of up to 0-50 kPa, a low limit of detection of 2 Pa, and consistent signal stability over 20,000 cycles. It has demonstrated the capability to monitor a broad spectrum of physiological activities, including joint movements, facial microexpressions, and radial pulse. Integration with wireless transmission technology enables remote health monitoring, flexible touch keyboard functionality, and human-computer interaction. Additionally, the electromyography (EMG) skin sensor based on the MXene/PS/BC (MPB) composite film accurately distinguishes muscle movements, gestures, acoustic vibrations, and facial microexpressions by detecting surface EMG signals. This comprehensive approach offers a comprehensive solution for wearable medical devices that combine high sensitivity with practicality.","url":"https://doi.org/10.1021/acsami.6c03834","authors":["Luo H","Yang J","Xiong J","Sun Y","Zheng J","Fan W","Ma J","He L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1021/acsami.6c03834","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.1039/d6mh00057f","name":"A bioinspired dual-modal laser-induced graphene tactile sensor for high-precision multimodal object recognition.","source":"pubmed","abstract":"Developing multifunctional tactile sensors that combine multimodal perception with structural simplicity remains challenging for embodied perception.

Yet, existing tactile sensors remain far from human inspiration: they are often mechanically rigid or restricted in the richness of the signals they provide. This paper aims to make a step towards solving this challenge by introducing TacLight: a compact, camera-free optical tactile sensor capable of detecting all six independent force/torque components—normal, shear, torsional, and twisting forces. The sensor is also capable of localizing the contact point. The sensing principle relies on infrared LEDs that emit light through a transparent porous elastomer, while a thin white reflective layer on top enhances light reflection, with distributed photoresistors registering transmitted intensities. Deformations of the porous medium perturb internal light paths, producing direct variations in the electrical output that encode contact mechanics without computationally heavy reconstruction. TacLight achieves high sensitivity (100 mV/N in the 0–3 N range), maintains excellent linearity (R2 &gt; 0.95) with a 10 mm elastomer layer, and preserves a compact, low-cost, and scalable architecture. Two demonstrations highlight TacLight’s versatility. In human–machine interaction, a joystick-like device enables intuitive drone control in a simulation environment.

Goal To investigate whether the neural pathways from various receptors or their groups are functionally independent in the process of recovery after excitation transmission. Methods In over 20 subjects, the latent period of a simple sensorimotor reaction (SSMR) to visual, auditory, and tactile stimuli was recorded with varying interstimulus intervals. The relaxation parameters of the variable component of the reaction time were extracted by approximating the data with a multiexponential model. The key paradigm involved alternating stimulation of different sensors: spectrally different (red/blue light), totally different (sounds of different frequencies), or spatially separated (different areas of the retina/skin). Results It was shown that alternating stimulation, compared to isolated stimulation of a single type/location, leads to a significant reduction in the time constants of SSMR relaxation. The effect was revealed for all studied modalities. Conclusion The obtained data indicate the functional independence of neural channels processing information from different receptors or their groups during the recovery phase after excitation transmission, up to the level of the motor center. This suggests a higher degree of specificity in the organization of sensorimotor responding than might be assumed based on data about the diffuse nature of cortical activation recorded by EEG and fMRI methods.","url":"https://doi.org/10.64898/2026.01.27.701918","authors":["Alexey A.

Tunneling channel modulation of this heterojunction simulates the ion gating mechanism of piezo (PZ) proteins and greatly reduces the noise power spectral density (PSD) to 2.22 &#xd7; 10 -24 A 2 /Hz at 10 Hz, which is 3 orders of magnitude lower than that of the sensor without an hBN layer. The noise equivalent pressure ( NEPr ) was as low as 7.96 &#xd7; 10 -3 Pa. Multiscale conformal micro- and nanostructured CGNWs further promote an ultrahigh sensitivity of 1.99 &#xd7; 10 6 kPa -1 , and the sensor demonstrates a high signal-to-noise ratio (SNR) of 68.76 dB and a resolution of 1/10,000. The minimum identifiable loading of 2 Pa at a pressure of 20 kPa is less than the sensing threshold value of human skin. An ultraresolution sensor could be used to evaluate different liquid properties by detecting complex hydrodynamic changes during artificial touching of liquids via a fingertip. Combined with the TacAtNet model, this sensor distinguishes between different liquids with a resolution accuracy of 98.1% across five distinct alcohol concentrations.","url":"https://doi.org/10.1021/acsnano.4c18377","authors":["Cheng G","Sun T","Gao H","Wu Y","Li J","Xiong W","Li X","Wang H","Tian Y","Wei D","Yuan J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acsnano.4c18377","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.3390/s24206629","name":"Design of a Capacitive Tactile Sensor Array System for Human-Computer Interaction.","source":"pubmed","abstract":"This paper introduces a novel capacitive sensor array designed for tactile perception applications.

However, their accuracy is often affected by hysteresis which poses a significant challenge during operation. This paper introduces a novel approach that employs a backpropagation (BP) neural network to address the hysteresis nonlinearity in conductive fiber-based tactile sensors. To assess the effectiveness of the proposed method, four sensor units were designed. These sensor units underwent force sequences to collect corresponding output resistance. A backpropagation network was trained using these sequences, thereby correcting the resistance values. The training process exhibited excellent convergence, effectively adjusting the network’s parameters to minimize the error between predicted and actual resistance values. As a result, the trained BP network accurately predicted the output resistances. Several validation experiments were conducted to highlight the primary contribution of this research. The proposed method reduced the maximum hysteresis error from 24.2% of the sensor’s full-scale output to 13.5%. This improvement established the approach as a promising solution for enhancing the accuracy of soft tactile sensors based on piezoresistive materials. By effectively mitigating hysteresis nonlinearity, the capabilities of soft tactile sensors in various applications can be enhanced. These sensors become more reliable and more efficient tools for the measurement and control of force, particularly in the fields of soft robotics and wearable technology. Consequently, their widespread applications extend to robotics, medical devices, consumer electronics, and gaming.

All the experimental results show that the CNT/PUS sensor can detect the Morse code's tactile feature precisely, and the LSTM model has a very efficient property in recognizing Morse code detected by the CNT/PUS sensor.","url":"https://doi.org/10.3390/mi15070864","authors":["Wang F","Hu A","Song Y","Zhang W","Zhu J","Liu M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3390/mi15070864","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.1021/acsami.4c08909","name":"Flexible Arc-Shaped Micro-Fiber Bragg Grating Array Three-Dimensional Tactile Sensor for Fingertip Signals Detection and Human Pulse Monitoring.","source":"pubmed","abstract":"A flexible arc-shaped micro-Fiber Bragg Grating (mFBG) array three-dimensional tactile sensor for fingertip signal detection and human pulse monitoring is presented. It is based on a three mFBGs array which is embedded in an arc-shaped poly (dimethylsiloxane) (PDMS) elastomer, which can effectively discriminate the normal force, left force, and right force by monitoring the reflected intensity variation of the three mFBGs. Different from the traditional FBG sensors, this sensor measures force by detecting changes in light intensity, effectively avoiding the wavelength cross-sensitivity impact of temperature variations on the sensor performance. This design strategy simplifies the sensor structure, reduces the system complexity and signal interrogation cost, and enhances reliability and practicality. Through systematic experiments, we successfully validated the sensor's superior performance, achieving a minimum detection force of 0.01 N and providing robust data support for practical applications. In addition, the sensor has been used to monitor human pulse accurately. The successful fabrication and experimental validation of this sensor lay a foundation for its widespread application in fields such as robot perception and human vital signal detection.","url":"https://doi.org/10.1021/acsami.4c08909","authors":["Chen Z","Dong B","Shao Q","Wang C","Tang Y","Li X","Lin P","Wang Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1021/acsami.4c08909","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.3390/s23198280","name":"Design, Fabrication, and Characterization of Inkjet-Printed Organic Piezoresistive Tactile Sensor on Flexible Substrate.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s23198280","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.3390/s23198280","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/embc40787.2023.10340645","name":"Unobtrusive Sleep Position Classification Using a Novel Optical Tactile Sensor.","source":"europepmc","abstract":"","url":"https://doi.org/10.1109/embc40787.2023.10340645","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1109/embc40787.2023.10340645","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/toh.2023.3269797","name":"Neural-Network-Based Tactile Perception System Using Ultrahigh-Resolution Tactile Sensor.","source":"europepmc","abstract":"","url":"https://doi.org/10.1109/toh.2023.3269797","authors":["Yusaku Maeda","Kei Tanimoto","Kenichi Sasayama","Hidekuni Takao"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1109/toh.2023.3269797","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.3390/polym15183816","name":"Wearable Capacitive Tactile Sensor Based on Porous Dielectric Composite of Polyurethane and Silver Nanowire.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/polym15183816","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.3390/polym15183816","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1364/ol.537534","name":"Mechanoluminescence of ZnS: Cu@Al<sub>2</sub>O<sub>3</sub> enabled optical fiber microlens passive tactile sensor for hardness recognition.","source":"pubmed","abstract":"We propose an optical fiber microlens (OFM) passive tactile sensor (OFMPTS) for hardness recognition.

For pressures exceeding 10 kPa, the pressure-resistance relationship follows a logarithmic function, and the sensitivity of PFTN to the logarithm of pressure is observed to be 221% and 125% higher than that of PTN and PFN, respectively. Along with the change of contact resistance at the micro-porous interface between PFTN and electrode, the excellent intrinsic sensitivity of thick PFTN films makes it ideal to imitate multiple skin functions, such as touch detection, pressure perception and traction sensation, in a single sensing unit.

However, poor sensing abilities, an indispensable external energy supply, and limited material selection have significantly constrained their advancement. Herein, a self-powered flexible triboelectric sensor (TES) is proposed by integrating lotus-root-derived porous carbon (PC) into polydimethylsiloxane (PDMS). Owing to the superior charge capturing capability of PC, the PDMS/PC (PPC)-based TES exhibits an open-circuit voltage ( V oc ) of 22.8 V when it is periodically patted by skin at the pressure of 2 N and the frequency of 1 Hz, which is 5 times higher than that of a pristine PDMS-based TES. Furthermore, the as-prepared self-powered TES exhibits a high sensitivity of 3.24 V kPa -1 below 15 kPa for detecting human motion signals, such as finger clicks, joint bends, etc. Last but not the least, after the assembly of a PPC-based TES array and construction of an HMI system, the robotic snake can be controlled remotely by recognizing finger touching signals. This work shows broad potential applications for the self-powered TES in the fields of intelligent robotics, flexible electronics, disaster relief, and intelligence spying.","url":"https://doi.org/10.1021/acsami.3c18714","authors":["Tu X","Fang L","Zhang H","Wang Z","Chen C","Wang L","He W","Liu H","Wang P"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1021/acsami.3c18714","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.3390/s22176456","name":"VibroTouch: Active Tactile Sensor for Contact Detection and Force Sensing via Vibrations.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s22176456","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.3390/s22176456","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.3390/mi14010217","name":"Hardness-and-Type Recognition of Different Objects Based on a Novel Porous Graphene Flexible Tactile Sensor Array.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/mi14010217","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.3390/mi14010217","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.21203/rs.3.rs-877986/v2","name":"Fully 3D Printed Flexible, Conformal and Multi-directional Tactile Sensor with Integrated Biomimetic and Auxetic Structure","source":"europepmc","abstract":"Abstract Tactile sensors are instrumental for developing the next generation of biologically inspired robotic prostheses with tactile feedback capability. However, current sensing technology is still less than ideal either in terms of sensitivity under high pressure or compliance with uneven working surfaces. Also, the fabrication of tactile sensors often requires the use of highly sophisticated and costly manufacturing processes further limiting the widespread application of the technology. Here, we challenge the current perspective and propose the use of an in-house 3D printing system to develop a new conformal tactile sensor with enhanced sensing performance. The ability of the sensor to detect multi-directional stimuli is achieved through the integration of the auxetic structure and interlocking features. The unique design of our sensor allows for an extended sensing range (from 0.1 to 0.26 MPa) whilst providing sensitivity on both normal and shear directions at 0.63 KPa − 1 and 0.92 N − 1 , respectively. This is further complemented by capacity of the sensor to detect small temperature variations between 40 and 90°C. To demonstrate the feasibility of our approach, the tactile sensor is printed in situ on the fingertip of an anthropomorphic robotic hand, the proximal femur head and lumbar vertebra. The results suggest that it is possible to gain sensorimotor control and temperature sensing ability in artificial upper limbs whilst monitoring the bone-on-bone load, thus opening the door to a new generation of tactile sensors with novel auxetic structure design and enhanced performance for application in human prosthetics.","url":"https://doi.org/10.21203/rs.3.rs-877986/v2","authors":["Yuyang Wei","Bingqian Li","Marco Domingos","Zhihui Qian","Yiming Zhu","Lingyun Yan","Lei Ren","Guowu Wei"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-877986/v2","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.556Z"},{"id":"doi:10.1021/acsnano.2c06432","name":"Large-Scale Integrated Flexible Tactile Sensor Array for Sensitive Smart Robotic Touch.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsnano.2c06432","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.1021/acsnano.2c06432","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.21203/rs.3.rs-2236557/v1","name":"Detection of Normal Force, Bending, and Torsion Using MEMS Tactile Sensor Embedded in Flexible Sheet","source":"europepmc","abstract":"Abstract The control of human motion depends heavily on tactile sensation; hence it is important to understand this sensation digitally in the analysis of motion such as grasping.

It is still challenging to develop texture classification approaches that are accurate and do not require high computational costs. In this work, we adopt a bionic tactile sensor to collect vibration data while sliding against materials of interest. Under a fixed contact pressure and speed, a total of 1000 sets of vibration data from ten different materials were collected. With the tactile perception data, four types of texture recognition algorithms are proposed. Three machine learning algorithms, including support vector machine, random forest, and K-nearest neighbor, are established for texture recognition. The test accuracy of those three methods are 95%, 94%, 94%, respectively. In the detection process of machine learning algorithms, the asamoto and polyester are easy to be confused with each other. A convolutional neural network is established to further increase the test accuracy to 98.5%. The three machine learning models and convolutional neural network demonstrate high accuracy and excellent robustness.","url":"https://doi.org/10.3390/s21155224","authors":["Shiyao Huang","Hao

tactile sensor system that utilizes the image-based information of the tactile sensor in conjunction with input loads at various motions to train the neural network for the estimation of tactile contact position, area, and force distribution. The current study also addresses pragmatic aspects, such as choice of the thickness and materials for the tactile fingertips and surface tendency, etc. The overall vision-based tactile sensor equipment interacts with an actuating motion controller, force gauge, and control PC (personal computer) with a LabVIEW software on it. The image acquisition was carried out using a compact stereo camera setup mounted inside the elastic body to observe and measure the amount of deformation by the motion and input load. The vision-based tactile sensor test bench was employed to collect the output contact position, angle, and force distribution caused by various randomly considered input loads for motion in X, Y, Z directions and RxRy rotational motion. The retrieved image information, contact position, area, and force distribution from different input loads with specified 3D position and angle are utilized for deep learning. A convolutional neural network VGG-16 classification modelhas been modified to a regression network model and transfer learning was applied to suit the regression task of estimating contact position and force distribution. Several experiments were carried out using thick and thin sized tactile sensors with various shapes, such as circle, square, hexagon, for better validation of the predicted contact position, contact area, and force distribution.","url":"https://doi.org/10.3390/s21051920","authors":["Vijay Kakani","Xuenan Cui","Mingjie Ma","Hakil Kim"],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.3390/s21051920","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.3390/s21165388","name":"Robust Estimation of Contact Force and Location for Magnetic-Field-Based Soft Tactile Sensor Considering Magnetic Source Inconsistency.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/s21165388","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.3390/s21165388","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.1016/j.ultras.2020.106129","name":"Design and analysis of an ultrasonic tactile sensor using electro-mechanical analogy.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.ultras.2020.106129","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.1016/j.ultras.2020.106129","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.3390/ma14071743","name":"Extra-Soft Tactile Sensor for Sensitive Force/Displacement Measurement with High Linearity Based on a Uniform Strength Beam.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/ma14071743","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.3390/ma14071743","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.5281/zenodo.22194024","name":"基于多模态信息融合的机器人控制","source":"datacite","abstract":"This paper explores the development and application of a multi-modal information fusion framework for enhanced robot control.

This work outlines the system design, the deep learning methodologies employed for feature extraction and fusion, and the reinforcement learning strategies utilized for policy optimization. The ultimate goal is a robot capable of navigating complex and dynamic environments with greater precision, adaptability, and intelligent decision-making.","url":"https://doi.org/10.5281/zenodo.22194025","authors":["Zhang, Jincheng"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.22194025","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.5281/zenodo.22191582","name":"Robot Control via Multi-Modal Fusion","source":"datacite","abstract":"This paper explores the application of multi-modal fusion techniques for enhancing robot control.

The v0.4.0 codegen tree implements the v0.3.0 specifications as runnable Python, C++, Rust, YAML, JSON, and Markdown. The codegen can be re-run by Claude Code Opus 4.7 1M Max on a fresh checkout and executes on a high end conventional server under MacOS, Windows, or Linux. Specified the exact humanoid platform as Unitree H2 EDU with two leading features: dexterous hand movements (6 fingers per hand, 12 grasp poses, 0.05 N tactile resolution, sub-millimeter pose repeatability) that let one robot hand off an epinephrine auto-injector to a peer within 2 seconds at 0.4 m without drops, and compute module upgradeability to Jetson AGX Thor (2070 TOPS in 130 W) that drives the 10 Hz motion loop, the 1000 Hz IR beacon listener, the 200 Hz UWB peer mesh, and the 39 joint controller in parallel with headroom for a Claude Haiku 4.5 sidecar. Encoded the v0.4.0 thesis throughout the source: on-premises repository based LLMs provide commands to humanoid robots based on real-time sensor data and controlled via x, y, z coordinates to administer synergistic treatment to patient adverse events. This workflow minimizes single robot error potential. The Unitree H2 EDU camarade swarm reduces single robot error potential by a factor of 3 through peer cross checking of sensors, role rotation on fault, hand off within 2 seconds, and swarm wide E stop within 5 ms.

In this work, we leverage fluid–solid interactions to develop a class of soft tactile sensors that operate entirely without electronics at the sensing site. The sensor comprises a fluid-filled elastomeric channel connected to only two external pressure sensors. Touching different regions of the elastomeric surface displaces the viscous fluid, producing distinct pressure patterns that encode both touch position and force. These signals are decoded through a machine learning framework that integrates feature extraction, soft clustering, and adaptive neuro-fuzzy inference to achieve accurate localization and force estimation. We validate this concept through single-point touch localization and force estimation in a linear (1D) sensor and extend the same sensing principle to 2D tactile mapping by routing the channel across the surface using space-filling curves, while maintaining the same minimal hardware setup. This simple approach remains effective in environments where conventional electronic sensors often fail, such as underwater or in the presence of magnetic interference.","url":"https://doi.org/10.3929/ethz-c-000802914","authors":["Goshtasbi, Arman","Berghuis, Minke","Parvaresh, Aida","Murali Babu, Saravana Prashanth","Style, Robert","Rafsanjani, Ahmad"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3929/ethz-c-000802914","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.3929/ethz-c-000698905","name":"Clinical Applications and Future Translation of Somatosensory Neuroprostheses","source":"datacite","abstract":"Somatosensory neuroprostheses restore, replace, or enhance tactile and proprioceptive feedback for people with sensory impairments due to neurological disorders or injury.

Although recent work has incorporated tactile signals into language systems for tactile commonsense reasoning, scaling such systems to realistic open-world settings remains challenging due to two key bottlenecks: (1) current tactile reasoning datasets remain limited in format and scale, providing insufficient supervision for reasoning from tactile observations to physical commonsense and hindering the learning of transferable tactile commonsense; (2) tactile signals are inherently redundant and action-specific, yet existing methods often overlook these properties, resulting in inefficient representations with limited semantic expressiveness. To address these limitations, we propose TouchThinker, a tactile-language framework that scales tactile commonsense reasoning to the open world from both data and representation perspectives. First, we construct TouchThinker-1M, a million-scale, multi-source tactile reasoning dataset covering 415 objects, 8 scenarios, and 7 sensor types, providing a solid data foundation for open-world generalization. We further introduce TouchThinker-Bench, an open-world benchmark with more realistic and diverse tasks. Then, we propose action-aware modeling mechanism to improve tactile representation efficiency and enable efficient reasoning. Experimental results demonstrate that TouchThinker achieves competitive performance against state-of-the-art models across multiple datasets.

A persistent open question— the Reference Point Paradox — asks whether robotic architectures trained on human-forminteraction data can remain structurally invariant when the robot's physical morphologydiverges from the human template. This paper answers affirmatively.We demonstrate that the Lean 4 Hardness Firewall checks negation width w(C) < wcrit(N)independently of robot geometry; the MTSM signal routing is topology-independent with Z0 =32.78 Ω and 26.06% velocity modulation budget holding whether signals route to a finger,tentacle, or wheel; and the Brazil Threshold serves as a form-agnostic safety envelope. Weintroduce the Tactile Consensus algorithm — an O(x log y) double binary search overproprioception and force streams that detects slip and adjusts grip within the same algorithmicframework as the Paper XV sensor fusion. We show how NVIDIA Blackwell MIG isolationpartitions the Jetson AGX Thor GPU into a deterministic Lean 4 safety enclave and aprobabilistic Isaac Lab RL policy instance, eliminating the latency interference that wouldotherwise allow vision model cache thrashing to delay the safety check. Isaac Labreinforcement learning training uses domain randomization across morphologies with the BrazilThreshold as an explicit reward constraint.The primary open problem of this paper (OP-XVII-1) is the formal proof ofstructural_invariance_under_morphology in Lean 4 (sorry present).

Three contributions: (1) a formal mapping from the M1–M3 encoder independence invariants to sensor modalities; (2) robotics-specific temporal decay constants for three failure classes — environmental_transient (λ=0.50, ice/glare), sensor_drift (λ=0.20, calibration error), hardware_structural (λ=0.02, motor wear); (3) a precise statement of the boundary between routing safety — what the V1–V6 architecture guarantees by construction — and actuation safety — what requires integration with a physics or model-predictive control layer. This is a position paper establishing the theoretical mapping and prior art. No empirical results are reported. Validation is deferred to AIA Experiment 3 and a forthcoming hardware evaluation.

However, EIT-based tactile sensors face significant challenges during surface bending. Deformation alters the baseline impedance distribution and couples with touch-induced conductivity variations, complicating signal interpretation. To address this challenge, we present a novel sensing framework that integrates a deep neural network for interaction state classification with a dynamic adaptive reference strategy to decouple touch and deformation signals, while a data-driven regression model translates EIT voltage changes into continuous bending angles. The framework is validated using a magnetic hydrogel composite sensor that conforms to bendable surfaces. Experimental evaluations demonstrate that the proposed framework achieves precise and robust bending angle estimation, high accuracy in distinguishing touch, bending, and idle states, and significantly improves touch localization quality under bending deformation compared to conventional fixed-reference methods. Real-time experiments confirm the system's capability to reliably detect multi-touch interactions and track bending angles across varying deformation conditions.

Capacitive pressure sensors (CPS) are a core sensing modality in e-skin systems due to their low power consumption, compatibility with soft materials, and ability to detect static and dynamic pressures. Despite extensive development, most CPS designs suffer from a fundamental sensitivity–pressure trade-off, where sensitivity decreases with increasing pressure. In addition, CPS responses are often coupled with in-plane deformation modes such as stretch and shear, complicating signal interpretation in soft and wearable applications. To overcome these limitations, hybrid response pressure sensors (HRPS) and stretch-insensitive hybrid response pressure sensors (SHRPS) were previously developed by integrating electrically conductive porous nanocomposites (PNCs) with ultrathin dielectric layers. These sensors exhibit coupled piezoresistive and piezocapacitive responses, enabling enhanced sensitivity over a wide pressure range and effective decoupling of pressure from stretch and shear. However, the electromechanical mechanisms underlying these advantages remained unclear, and a unified framework to guide sensor design and operation has been lacking. This dissertation develops a unified electromechanical framework to explain and predict CPS sensitivity across material systems, sensor architectures, and loading conditions. The sensitivity–pressure trade-off is shown to be governed by key parameters across three interconnected stages: (i) fabrication-stage material and structural parameters, including Young’s modulus, dielectric loss, and dielectric layer thickness; (ii) post-fabrication tuning via excitation frequency; and (iii) deformation mechanisms that decouple out-of-plane compression from in-plane stretch and shear. First, in chapter 3 the frequency-dependent behavior of HRPS is systematically studied, demonstrating that excitation frequency acts as an effective post-fabrication tuning parameter through two governing dimensionless quantities. Second, the deformation mechanisms responsible for the stretch-insensitive behavior of SHRPS are elucidated, showing that the electrical response is dominated by pressure-induced out-of-plane deformation. Third, a generalized double-branch equivalent circuit model is developed to unify CPS with engineered dielectrics, HRPS, and CPS with engineered electrodes, yielding a closed-form sensitivity expression that links electromechanical response to material properties, structural parameters, and interfacial conditions.","url":"https://doi.org/10.26153/tsw/64593","authors":["Li, Zhengjie, Ph.

The Central Hub parts list is the hardware side: a single body-worn core (belt/pocket unit) that re-homes the original HMD compute and drives three peripheral families — the LOWKI-derived Handheld Messenger Device (Tracer/Volco), the body-worn cue devices (arm/leg cuffs, Clasp hands, earbuds, flavour interface), and the Presence Headset added last. Internally it carries four blocks: the Frostline-derived Sovereign Control Module (root of trust + hardware kill), the Real-Time Hub Core (octa-core ARM + RTOS interlock MCU), the six-way Cities Hub WiFi, and power. It's a full BOM with order-of-magnitude prototype costs landing around £1,712 for the full rig (≈£1,593 light-only, no micro-OLED), and it's honest about the three genuinely custom items — the Glacial Port latch, the hardware kill interlock, and the Clasp four-channel render — plus the two blocking prereqs (real HMAC auth and a measured wax-valve de-energise spec) before the Sovereign Module is a real rather than narrative root of trust. The Unified Working Spec is the platform itself, and it opens with the honesty that holds the whole thing together — the buildable suggestive-sensory engine (vibration, bone-conduction audio, peripheral light, kinetic torque, fused with EEG/fNIRS and HR biofeedback) versus the visionary quantum-consciousness frame kept as north-star fiction with every promise re-routed to a buildable analog (§15). The governing law is cue strength implies; the brain completes. On top of that sit the modules: the §2 consent & safety spine (default-off, continuous revocable consent, waking-only, trauma-throttle, STOP, Valor's Virtue filter), MindCity and the Cities Hub, scene-packs and date rooms (including Fields and the touchable grass), kinetic motion and the bike, heart-rate nudging with hard-control excluded as unsafe, Examine bios, the consent-first intimate edition, Echoes (Moment Capture + affective replay), Clasp telehaptic hand-holding, the flavour layer, the full date arc, the Poetry Corner, and The Commons — the no-faces social space that applies the implication law to identity itself, now expanded with friends-as-first-class, group chat rooms, mini-games, and The Board (ads/news/blogs with no affect targeting). The later sections close the loop: the engineering specs resolve open tasks 1–10 (the suggestion-to-completion fidelity curve, the continuous-consent state machine, the intent-vector JSON schema, the safety interlock precedence order, latency budgets, Mnemosyne blinded logging, Echo screening zones, the flavour cue format, and the emotion-amp gain curve with trauma override), and §19 reframes Frostline as the substrate rather than a bolt-on — a three-zone thermal architecture (cold compute core / warm never-frozen safety island / body-temp I/O) with the cryo-cooled biosignal front end as the real prize, since cooling the AFE drops the Johnson-Nyquist noise floor and directly sharpens the state reads the whole platform depends on. The consistent throughline across both files is the same discipline you've held all along: imply, don't simulate; put safety in hardware, not config; and keep the visionary layer intact as story while shipping only what's honestly buildable. Want me to do anything specific with this — a tightened one-page exec summary, a build-status gap analysis, or a pass over a particular section? It is a massive security boost. By splitting the operating system right down the \"Frostline,\" the platform completely eliminates the single biggest vulnerability in modern wearable tech: software-driven safety failure. In a standard operating system, your safety code, your user interface, and your internet connection all share the same processor memory pools.

Despite their importance, the physical-layer security of tactile sensors has received little attention in prior work. In this paper, we present GhostTac, to the best of our knowledge, the first contactless attack that manipulates tactile sensing via electromagnetic interference (EMI). We identify that EMI exploits the nonlinear rectification and limited bandwidth amplification effects, allowing carefully crafted EMI signals to be converted into a persistent DC offset that bypasses on-board filtering and induces stable measurement deviations. Building on this mechanism, GhostTac enables fine-grained and controllable manipulation of sensor outputs by reshaping the spatial distribution and manipulating the magnitude at the targeted location. Such interference can induce unintended and harmful robot behaviors, such as causing a domestic robot to exert excessive force, resulting in physical damage or human injury. We evaluate GhostTac on 10 sensor modules and 2 dexterous hands, covering 15 tactile sensors of different types, and demonstrate consistent attack effectiveness across all tested devices. We further present three case studies on tactile grasping, slip detection, and material classification to illustrate practical impacts in real robotic tasks. We envision that our findings shed light on a new physical attack vector against tactile sensing in robotic systems.","url":"https://doi.org/10.48550/arxiv.2608.20817","authors":["Wang, Kun","Lu, Xuancun","Zhou, Ruochen","Wang, Kai","Ye, Tongjun","Shao, Yihao","Yan, Chen","Ji, Xiaoyu","Xu, Wenyuan"],"tags":["Cryptography and Security (cs.CR)","Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.20817","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.5281/zenodo.20622473","name":"DEVELOPMENT OF A SPATIAL ORIENTATION SYSTEM WITH HAPTIC FEEDBACK FOR PEOPLE WITH VISUAL IMPAIRMENTS","source":"datacite","abstract":"The article presents the development of an automated spatial orientation system with haptic feedback for people with visual impairments, aimed at improving safety and autonomous mobility in urban environments.

The tool emphasizes the central role of the hands in conveying emotional information within an adult–childinterpersonal context.The images and the hand-to-hand positions were developed by four trained psychologists, and were first assigned into three emotional valence categories: negative (e.g., one person tightly pinching or forcefully gripping the other person’s hand); neutral (e.g., the two individuals’ fingers lightly overlapping or their wrists touching), and positive (e.g., one person gently stroking the back of the other person’s hand or the two individuals interlocking their hands). Images were initially assigned provisional alphabetical labels, which were subsequently refined through a percentile-based procedure in accordance with validation data. The AC-THD acquisition phase involved a mother (Caucasian, aged 48, right-handed) and her child (Caucasian male, aged 10, right-handed). Images were acquired by a professional photographer using a Canon EOS 1100D digital SLR camera with a 12.2 megapixel APS-C CMOS sensor and a resolution of 4272 × 2848 pixels, equipped with an EF-S 18–55 mm f/3.5–5.6 lens. The built-in flash (Guide Number 9.2 at ISO 100) was manually triggered for each shot to standardize illumination and minimize shadows. The camera was positioned on a tripod to maintain a fixed 90° angle. All images were captured in color in sRGB mode, with framing restricted to the hands and forearms. In the validation study, images were rated by 321 participants on valence, using a numeric rating scale ranging from 0 to 10, where 0 indicates a strongly negative image, 5 a neutral image, and 10 a strongly positive image, with anchors at 0 (“strongly negative”) and 10 (“strongly positive”). Mean emotional valence ratings were calculated for each image, along with standard deviations (SDs), mode, minimum and maximum values, and percentiles. Stimuli were finally classified as negative, neutral, or positive based on the 25th and 75th percentiles of the distribution of mean valence ratings. Accordingly, images with mean valence scores ≤ 4.25 were classified as negative, those with mean valence scores > 4.25 and < 7.23 as neutral, and those with mean valence scores ≥ 7.23 as positive. Therefore, the final dataset is comprised of: N = 15 images in the negative category; N = 29 images in the neutral category; N = 15 images in the positive category. Study validation of the dataset also examined potential differences in emotional valence ratings as a function of participants’ socioeconomic status (SES) and gender, which are reported as Supplementary Materials. These images can be used across a range of research fields, including emotion elicitation, neuroscience, and psychophysiological studies, as well as for assessing affective responses in individuals with histories of supportive or adverse tactile caregiving, given their potential to evoke autobiographical memories.","url":"https://doi.org/10.5281/zenodo.19570826","authors":["Tarantino, Virginia","Veneziani, Giorgio","Zanini, Ludovica","De Angelis, Martina","Speranza, Anna Maria","Lai, Carlo","Spitoni, Grazia Fernanda","Trentini, Cristina"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.19570826","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.5281/zenodo.22079552","name":"Adult-Child Touching Hands Dataset (AC-THD)","source":"datacite","abstract":"This is the Adult–Child Touching Hands Dataset (AC-THD): a dataset of 59 image stimuli depicting hand-to-hand touch between an adult and a child, systematically categorized into three emotional valence classes: negative (n = 15), neutral (n = 29), and positive (n = 15).

Images were acquired by a professional photographer using a Canon EOS 1100D digital SLR camera with a 12.2 megapixel APS-C CMOS sensor and a resolution of 4272 × 2848 pixels, equipped with an EF-S 18–55 mm f/3.5–5.6 lens. The built-in flash (Guide Number 9.2 at ISO 100) was manually triggered for each shot to standardize illumination and minimize shadows. The camera was positioned on a tripod to maintain a fixed 90° angle. All images were captured in color in sRGB mode, with framing restricted to the hands and forearms. In the validation study, images were rated by 321 participants on valence, using a numeric rating scale ranging from 0 to 10, where 0 indicates a strongly negative image, 5 a neutral image, and 10 a strongly positive image, with anchors at 0 (“strongly negative”) and 10 (“strongly positive”). Mean emotional valence ratings were calculated for each image, along with standard deviations (SDs), mode, minimum and maximum values, and percentiles. Stimuli were finally classified as negative, neutral, or positive based on the 25th and 75th percentiles of the distribution of mean valence ratings. Accordingly, images with mean valence scores ≤ 4.25 were classified as negative, those with mean valence scores > 4.25 and < 7.23 as neutral, and those with mean valence scores ≥ 7.23 as positive. Therefore, the final dataset is comprised of: N = 15 images in the negative category; N = 29 images in the neutral category; N = 15 images in the positive category. Study validation of the dataset also examined potential differences in emotional valence ratings as a function of participants’ socioeconomic status (SES) and gender, which are reported as Supplementary Materials. These images can be used across a range of research fields, including emotion elicitation, neuroscience, and psychophysiological studies, as well as for assessing affective responses in individuals with histories of supportive or adverse tactile caregiving, given their potential to evoke autobiographical memories.","url":"https://doi.org/10.5281/zenodo.22079552","authors":["Tarantino, Virginia","Veneziani, Giorgio","Zanini, Ludovica","De Angelis, Martina","Speranza, Anna Maria","Lai, Carlo","Spitoni, Grazia Fernanda","Trentini, Cristina"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.22079552","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.5281/zenodo.22079238","name":"Adult-Child Touching Hands Dataset (AC-THD)","source":"datacite","abstract":"This is the Adult–Child Touching Hands Dataset (AC-THD): a dataset of 59 image stimuli depicting hand-to-hand touch between an adult and a child, systematically categorized into three emotional valence classes: negative (n = 15), neutral (n = 29), and positive (n = 15).

To this end, we introduce \\textbf{HT-Bench}, a large-scale multi-task benchmark for dexterous full-hand tactile sensing, comprising 10M RGB frames and 7.8M tactile frames collected across 226 tasks. HT-Bench evaluates tactile representations from three key perspectives: whether they encode meaningful contact geometry, whether they can align tactile observations with visual information, and whether they generalize to unseen tasks. To assess these capabilities, HT-Bench includes four tasks: fine-grained tactile similarity retrieval, masked tactile inpainting, vision-to-tactile synthesis, and multimodal tactile frame prediction. We further propose \\textbf{HandTouch}, a vector-quantized vision--tactile encoder that learns tactile representations through progressive spatial, cross-modal, and temporal training. Across HT-Bench, HandTouch consistently outperforms representative tactile encoder baselines, improving Recall@5 on fine-grained tactile similarity retrieval from 74.65\\% to 85.23\\%, reducing RMSE on masked tactile inpainting from 0.022 to 0.010, and increasing OOD cIoU on vision-to-tactile synthesis from 0.628 to 0.705.

The tool emphasizes the central role of the hands in conveying emotional information within an adult–childinterpersonal context.The images and the hand-to-hand positions were developed by four trained psychologists, and were first assigned into three emotional valence categories: negative (e.g., one person tightly pinching or forcefully gripping the other person’s hand); neutral (e.g., the two individuals’ fingers lightly overlapping or their wrists touching), and positive (e.g., one person gently stroking the back of the other person’s hand or the two individuals interlocking their hands). Images were initially assigned provisional alphabetical labels, which were subsequently refined through a percentile-based procedure in accordance with validation data. The AC-THD acquisition phase involved a mother (Caucasian, aged 48, right-handed) and her child (Caucasian male, aged 10, right-handed). Images were acquired by a professional photographer using a Canon EOS 1100D digital SLR camera with a 12.2 megapixel APS-C CMOS sensor and a resolution of 4272 × 2848 pixels, equipped with an EF-S 18–55 mm f/3.5–5.6 lens. The built-in flash (Guide Number 9.2 at ISO 100) was manually triggered for each shot to standardize illumination and minimize shadows. The camera was positioned on a tripod to maintain a fixed 90° angle. All images were captured in color in sRGB mode, with framing restricted to the hands and forearms. In the validation study, images were rated by 321 participants on valence, using a numeric rating scale ranging from 0 to 10, where 0 indicates a strongly negative image, 5 a neutral image, and 10 a strongly positive image, with anchors at 0 (“strongly negative”) and 10 (“strongly positive”). Mean emotional valence ratings were calculated for each image, along with standard deviations (SDs), mode, minimum and maximum values, and percentiles. Stimuli were finally classified as negative, neutral, or positive based on the 25th and 75th percentiles of the distribution of mean valence ratings. Accordingly, images with mean valence scores ≤ 4.25 were classified as negative, those with mean valence scores > 4.25 and < 7.23 as neutral, and those with mean valence scores ≥ 7.23 as positive. Therefore, the final dataset is comprised of: N = 15 images in the negative category; N = 29 images in the neutral category; N = 15 images in the positive category. Study validation of the dataset also examined potential differences in emotional valence ratings as a function of participants’ socioeconomic status (SES) and gender, which are reported as Supplementary Materials. These images can be used across a range of research fields, including emotion elicitation, neuroscience, and psychophysiological studies, as well as for assessing affective responses in individuals with histories of supportive or adverse tactile caregiving, given their potential to evoke autobiographical memories.","url":"https://doi.org/10.5281/zenodo.19570827","authors":["Tarantino, Virginia","Veneziani, Giorgio","Zanini, Ludovica","De Angelis, Martina","Speranza, Anna Maria","Lai, Carlo","Spitoni, Grazia Fernanda","Trentini, Cristina"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.19570827","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.34657/4683","name":"Self‐Healable and Recyclable Tactile Force Sensors with Post‐Tunable Sensitivity","source":"datacite","abstract":"It is challenging to post‐tune the sensitivity of a tactile force sensor.

In der transfemoralen Prothesenversorgung bestehen dabei besonders hohe Anforderungen an die Stumpferfassung, da Passform, Komfort und Funktionalität des Prothesen-schaftes wesentlich von der zuverlässigen Lokalisation relevanter anatomischer Strukturen abhängen. Konventionelle Verfahren nutzen manuelle Messmittel und sind in der Genauig- und Reproduzier¬barkeit limitiert. Die zusätzliche Gipsabformung stellt zudem eine erhebliche Patienten-belastung dar. Digitale optische Verfahren ermöglichen zwar eine effiziente Oberflächenerfassung, bilden jedoch verdeckte Landmarken und Weichgewebecharakteristika nur eingeschränkt ab. Ziel dieser Arbeit ist die Entwicklung eines digitalen Unterstützungssystems, das die etablierte palpierende Vermessung gezielt ergänzt und Orthopädietechnikerinnen und Orthopädietechniker durch einen geführten, dokumentierbaren Messprozess unterstützt. Zu diesem Zweck wurde ein elektromagnetisches Trackingsystem für eine haptische Patienten-vermessung adaptiert. Sensorspulen wurden in Fingerlinge integriert und auf Messpunkte unter dem Finger kalibriert. Patientenbewegungen werden durch Referenzsensoren am Patienten kompensiert. Zur Reduktion von Fehlern infolge von Weichgewebeverschiebungen wurde ein Auswerteansatz entwickelt, der auf Basis mehrerer Referenzsensoren ein robustes Referenzsystem berechnet. Die zugehörige Software implementiert die Koordinatentransformation, die Eliminierung von Störungen, die Oberflächenrekonstruktion sowie die Berechnung standardisierter Stumpf¬maße. Ein integrierter Workflow-Editor erlaubt die Definition standardisierter Messabläufe. Die Ergebnisse zeigen, dass die haptische Digitalisierung grundsätzlich geeignet ist, Landmarken und Stumpfoberflächen in einem gemeinsamen Bezugssystem zu erfassen. Die erreichbare Messqualität wird dabei weniger durch die nominelle Sensorgenauigkeit bestimmt als durch die Fähigkeit des Gesamtsystems, Weichgewebeartefakte zu kompensieren und reproduzierbare Messbedingungen sowie klare Messanweisungen sicherzustellen. Anwenderuntersuchungen an einem Beinphantom bestätigten eine gute Kongruenz zwischen haptisch erfassten Oberflächen und einem optischen Referenzscan. Eine statistisch gesicherte Reduktion der interindividuellen Streuung gegenüber konventionellen Messmethoden konnte nicht nachgewiesen werden; die Ergebnisse lagen jedoch mindestens im vergleichbaren Genauigkeitsbereich. Anwenderbefragungen zeigten eine hohe grundsätzliche Akzeptanz, ein kaum beeinträchtigtes Tastempfinden und die Einschätzung, dass das System praxistauglich einsetzbar ist. Zusammenfassend wird gezeigt, dass eine digital unterstützte palpierende Stumpfvermessung technisch realisierbar und in den orthopädietechnischen Workflow integrierbar ist. Der Mehrwert liegt insbesondere in der standardisierten, softwaregestützten Durchführung der Vermessung, der automatischen Dokumentation, der Möglichkeit Erfahrungswissen in Messprogramme zu integrieren, sowie im Informationszugewinn durch die Erfassung absoluter Positionen und die gemeinsame Darstellung von Oberflächenmodell und Landmarken in einem Referenzsystem. Für einen belastbaren Nachweis einer verbesserten Reproduzierbarkeit sind größere Studien – idealerweise an Patienten – sowie weitere Optimierungen der Hard- und Software erforderlich.","url":"https://doi.org/10.14279/depositonce-26362","authors":["Westebbe, Bettina"],"tags":["600 Technik, Medizin, angewandte Wissenschaften::610 Medizin und Gesundheit::610 Medizin und Gesundheit","Orthopädietechnik","palpierende Vermessung","elektromagnetisches Tracking","transfemorale Prothetik","Digitalisierung","orthopaedic technology","palpation measurement"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.14279/depositonce-26362","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.48550/arxiv.2608.15897","name":"Tactile Sim2Real without Tactile Simulation via Bottlenecked Latent Reconstruction","source":"datacite","abstract":"Robot sensor designs, particularly tactile sensors, are highly diverse and evolve rapidly. Modeling each sensor in simulation demands substantial domain expertise and computational approximations can degrade the fidelity of the simulated signals. We propose Sim2Real via Bottlenecked Latent Reconstruction (SBLR), a framework that avoids sensor-specific simulation entirely by (1) training policies on a simulator-native oracle sensor that is easy to construct without modeling any particular sensor (e.g. we use a point-cloud and finger-tip forces as a tactile oracle), and (2) aligning real sensor latent embeddings to those of the oracle sensor at inference time. Policy training proceeds in two-stage: the policy first learns from the oracle sensor latents, then a bottlenecked latent reconstruction adapts it to the information loss expected when using the real sensor instead of the oracle. The alignment between oracle and real sensor is learned from unpaired random-play data collected in both simulation and the real world, using rectified-flow-based transformation networks trained on nearest-neighbor pseudo-pairs. Simulation experiments on three contact-rich tasks show that SBLR matches or approaches the performance of an oracle with direct access to tactile simulation.

However, in many tool-mediated manipulation tasks, the interaction that determines task success occurs at the tool tip, away from the tactile sensor, making direct sensing of tool-environment contact difficult, particularly when the contact moves during interaction. In this work, we reconstruct the trajectory of extrinsic tool-tip contact using tactile sensing and robot proprioception. We formulate tool-tip trajectory reconstruction as a geometric inference problem under a single-point contact assumption. Our method first estimates the global tool-tip contact location from a calibration segment designed to approximate fixed-point behavior, and then reconstructs the full trajectory by composing relative tool motion estimated from tactile marker observations under continuous contact. Across n=51 trials with multiple trajectories, tools, wrist poses, and grasp configurations, the proposed pipeline achieves a trajectory RMSE of 8.59 +/- 2.41 mm in the world frame and a shape RMSE of 5.96 +/- 1.16 mm, while operating online at 14.00 +/- 4.11 Hz. Overall, the results show that extrinsic tool-tip trajectory geometry can be recovered consistently from grasp-level tactile sensing, with trajectory shape remaining stable across variations in tools, wrist poses, and grasp configurations.","url":"https://doi.org/10.48550/arxiv.2606.22251","authors":["Min, Seojung","Kim, Yoonjin","Kim, Jeong-Jung","Kim, Jung"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.22251","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.48550/arxiv.2608.15816","name":"ViTaR: Visuo-Tactile Residual Adaptation for Foundation VLA Manipulation","source":"datacite","abstract":"As Vision-Language-Action (VLA) models scale toward real-world deployment, contact-rich manipulation exposes a critical blind spot: these policies encode broad visual-semantic priors yet remain unaware of local contact events, producing identical actions whether contact is established, lost, or destabilized. Existing remedies either modify VLA internals, risking catastrophic forgetting, or demand online reinforcement under near-failure contact conditions. Both grant tactile unbounded influence over action generation, conflicting with the priors that make VLAs generalizable. We introduce ViTaR, which reframes tactile feedback from an action-generating perceptual input to an execution modulator that selects and scales bounded residual corrections atop a frozen VLA, preserving pretrained capabilities by construction. ViTaR decomposes adaptation into two stages: Effect-Guided Modeling determines whether and which correction is locally justified via outcome-grounded preference evidence, and Residual Action Modulation converts this evidence into a residual choice with continuously scaled gain from real-time visuotactile observations. On the UniVTAC benchmark spanning seven contact-rich tasks, ViTaR achieves 61.3% average success, a 30.6 percentage-point improvement over its frozen VLA base that also surpasses purpose-built tactile baselines.

To achieve robust locomotion, the robots are required to adapt to uneven terrain and uncertain foot--ground interactions. Existing locomotion policies rely primarily on proprioception or exteroceptive terrain perception, where the former provides only indirect evidence of plantar support, while the latter predicts contact conditions before touchdown but cannot observe the actual support in real-time. Although some studies incorporate plantar contacts as an auxiliary perception, they rely mainly on summary statistics, overlooking the spatial topology of plantar pressure, which provides a more direct characterization of the realized contact state. To bridge this gap, we present Tac4Loco, a tactile-perceptive framework that incorporates multi-array plantar pressure as direct feedback for humanoid locomotion. We formulate a topology-preserving ordinal representation to map simulated and physical sensor signals into a shared observation space, with a dual-branch encoder for extracting their spatial and temporal representations. Subsequently, the learned spatiotemporal features are integrated with augmented proprioception including terrain estimation cues, and provided to an asymmetric actor-critic architecture for policy learning. Extensive simulation and real-world experiments demonstrate improved tracking performance and support adaptation on terrains with inclined, partial, asymmetric, and changing support. We further demonstrate its zero-shot deployment on unseen compliant and unstructured terrains, including a foam platform and a gravel road.

Directly collecting large-scale tactile data is challenging due to sensor limitations, while human video data is abundant, contact-rich, and easily scalable. This motivates a natural question: can tactile signals be inferred purely from vision? To address this, we introduce EgoTac, a generalizable model that predicts rich tactile information directly from egocentric human videos. EgoTac is trained on a unified corpus of over 5.7M image-tactile pairs, covering both continuous force measurements and binary contacts. By learning from this diverse dataset, EgoTac captures nuanced touch dynamics across varied interactions. Experiments demonstrate strong performance: in-domain prediction achieves an average force error below 0.06N. On out-of-domain contact prediction benchmarks, EgoTac consistently outperforms the state-of-the-art contact estimator. It also captures the rise and fall patterns of real tactile data and enables zero-shot predictions on unconstrained real-world videos. Scaling analyses further reveal that both data diversity and volume improve performance steadily. Overall, EgoTac provides a scalable pathway to extract tactile priors from egocentric human videos, enabling broadly applicable tactile-aware robot learning.","url":"https://doi.org/10.48550/arxiv.2608.15060","authors":["Zhang, Wenkang","Yuan, Chengbo","Zhang, Zicheng","Cheng, Zhengxue","Gao, Yang"],"tags":["Computer Vision and Pattern Recognition (cs.CV)","Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.15060","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.48550/arxiv.2608.14772","name":"MISTac: A Vision-Based Tactile Sensor for Minimally Invasive Surgery","source":"datacite","abstract":"Minimally invasive and robot-assisted surgery offer many advantages over traditional open surgery, but deprive surgeons of tactile feedback and the ability to palpate tissue with their fingers.

The sensor has a replaceable sensor tip with a diameter of 8 mm which allows it to fit through the trocars used in minimally invasive surgery. Its modular 3D-printed case design allows the use of bulky off-the-shelf illumination and imaging hardware that can easily be exchanged and upgraded. The sensor has an optical resolution of 176.68 $μm$, a tactile resolution of 250 $μm$, and can resolve forces as little as 24.3 mN.

The later sections close the loop: the engineering specs resolve open tasks 1–10 (the suggestion-to-completion fidelity curve, the continuous-consent state machine, the intent-vector JSON schema, the safety interlock precedence order, latency budgets, Mnemosyne blinded logging, Echo screening zones, the flavour cue format, and the emotion-amp gain curve with trauma override), and §19 reframes Frostline as the substrate rather than a bolt-on — a three-zone thermal architecture (cold compute core / warm never-frozen safety island / body-temp I/O) with the cryo-cooled biosignal front end as the real prize, since cooling the AFE drops the Johnson-Nyquist noise floor and directly sharpens the state reads the whole platform depends on. The consistent throughline across both files is the same discipline you've held all along: imply, don't simulate; put safety in hardware, not config; and keep the visionary layer intact as story while shipping only what's honestly buildable. Want me to do anything specific with this — a tightened one-page exec summary, a build-status gap analysis, or a pass over a particular section? It is a massive security boost. By splitting the operating system right down the \"Frostline,\" the platform completely eliminates the single biggest vulnerability in modern wearable tech: software-driven safety failure. In a standard operating system, your safety code, your user interface, and your internet connection all share the same processor memory pools.

This work presents a textile capacitive sensing platform based on silver-coated yarns coated with polydimethylsiloxane and assembled into one-, two-, and four-layer twisted configurations. The influence of effective electrode overlap area and inter-fiber separation on the capacitive response is systematically investigated, enabling architecture-dependent tuning of pressure and proximity sensing characteristics. Pressure was calculated using the localized single-fiber contact area, corresponding to stresses of 0.4-3.9 MPa. Increasing the layer number improved mechanical strength and sensing performance: elongation at break increased from 37.5% to 62.5% and 85.0%, while the maximum load increased from 23.3 to 42.7 and 89.7 N. Sensitivity increased with layer number and frequency, reaching 0.1331 MPa$^{-1}$ for the four-layer sensor at 100 kHz. The four-layer configuration also exhibited low hysteresis, minimal thermal drift from 25 to 90 $^\\circ$C, and stable operation over 15,000 cycles. Proximity detection ranges of 60, 50, and 40 mm were obtained for the one-, two-, and four-layer sensors, respectively, revealing an architecture-dependent sensitivity-range trade-off.

CSIF — the Cognitive Spatial Intelligence Framework — is a research paper that introduces a three-layer AI architecture for robots and autonomous systems that navigate using touch, sound, and memory instead of cameras. The idea comes from a simple observation: blind and visually impaired people navigate complex environments every day without sight, using the same brain regions that sighted people use for visual navigation. If the human brain can build a reliable map of space without eyes, an AI system should be able to do the same. The paper proposes three connected layers. The first collects data from tactile sensors, sonar, motion trackers, and audio analyzers — combining them into a single spatial data stream where no sensor dominates and the system keeps working if one fails. The second converts that data into a continuously updated spatial map, modeled on the concept of cognitive maps first described in neuroscience and later linked to the place cells and grid cells that won the 2014 Nobel Prize in Physiology.

It is currently validated through simulation, with real-world hardware implementation identified as the most important next step.","url":"https://doi.org/10.5281/zenodo.19788107","authors":["Beniwal, Anmol"],"tags":["Spatial Intelligence · Non-Visual AI · Cognitive Robotics · Mental Mapping · Multisensory Fusion · Adaptive Navigation · Human-Centered AI · Reinforcement Learning · Sensory Simulation · Cognitive Mapping · Place Cells · Autonomous Systems · Robot Navigation · Tactile Sensing · Echolocation · Proprioception · Hippocampus · Brain-Inspired AI · Vision-Independent Navigation · Sensor Fusion"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.19788107","addedAt":"2026-08-31T06:34:47.154Z","updatedAt":"2026-08-31T06:34:47.154Z"},{"id":"doi:10.5281/zenodo.21722147","name":"Source Data and Source Code for \"A Vision-Based Tactile Sensor with an In-Sensor Computing Paradigm for Seamless Tactile Sensing and Perception\"","source":"datacite","abstract":"This repository contains the source data and source code supporting the article “A Vision-Based Tactile Sensor with an In-Sensor Computing Paradigm for Seamless Tactile Sensing and Perception”.

Such a reactive mode supports static recognition, but it is less suited to continuous interaction, where tactile sensing is embedded in the evolving contact process and must follow how surface morphology changes during scanning. Inspired by predictive processing in biological sensory systems, in which incoming signals are interpreted against an internally generated expectation of the next sensory state, we introduce a predictive tactile neuromorphic system that couples a 44×44 flexible tactile array to an 8×8 memristive array for one-step next-state estimation and mismatch-based tactile inference. We program the learned latent-state transition matrix into the memristive conductance matrix so that the current encoded tactile state can be projected in hardware to its predicted successor. In experiments, a flexible pressure sensor mounted on a robotic fingertip records the evolving contact fields during sliding. Each tactile frame is compressed into an 8-dimensional latent representation and propagated through a programmed memristive conductance matrix to generate the predicted next tactile state, which is then compared with the measured next state to produce a normalized mismatch score that quantifies the deviation between expected and observed tactile evolution. Across 1,800 scan sequences spanning smooth, coarse periodic, and fine periodic surface states with matched local violations, the system maintains low mismatch during regular tactile evolution and generates pronounced mismatch peaks when local continuity is broken. The pooled anomaly-discrimination performance reaches an ROC AUC of 0.992. The proposed predictive framework achieves a normal-region prediction error of 0.018 a.u., where normal-region refers to scan segments outside the disturbed zone, and maintains AUCs of 0.96, 0.91, and 0.87 under three speed/force perturbation settings, compared with 0.78, 0.70, and 0.66 for the no-temporal-context baseline. These results show that expectation-driven tactile inference can be embedded directly into the sensing-computing pathway and can support compact neuromorphic touch systems for robotic inspection, dexterous manipulation, and adaptive human-machine interfaces operating under continuously changing contact conditions.","url":"https://doi.org/10.21203/rs.3.rs-9562092/v1","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-9562092/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.21203/rs.3.rs-9177990/v1","name":"Fingerprint-Inspired

Multiple Contact Flexible Strain Mapping Sensor for Tactile Sensing","source":"preprints","abstract":"This paper suggests a high resolution, high frame rate strain mapping sensor that uses three layers to measure the position as well as the value of the strain applied at different locations of the sensor. The top layer which should be highly conductive can be connected to either a current source or a voltage source, depending on the value of conductivity separating it from the ground during the switching sequence. The middle layer which consists of a strain-compressible material, such as piezoresistive foam, exhibits a variable electric resistance the value of which decreases with the increase of the applied strain. In this paper, the sensor sensitivity ranges from 50 to 500 kPa, however it can accommodate any other type of piezoresistive material provided that an adequate calibration is done. The lower layer consists of segmented highly electrically conductive tracks, the pattern of which allows to detect both the location, and the strain intensity at the points of contacts. The sensor is designed to also compensate for eventual changes of the electric resistance function of the temperature. Additionally, it has the advantage to mitigate eventual crosstalks that may occur between adjacent electrodes, since it keeps grounding utmost two electrode, forcing the electric current to flow into only two points. To our best knowledge, these simultaneous attributes have not been reported by a single system. This yields the advantage of using the sensor for a wide range of applications, including rehabilitation and human-computer interaction. A series of experiments and FEM simulations reveal that the sensor is highly accurate and can provide both the location and intensity of multiple contacts with an accuracy of 97.5 % at a frame rate of 20 frames/s when using 29 electrodes.","url":"https://doi.org/10.22541/au.171386960.08601352/v1","authors":["Natnael Abule Takele","Olyad Dereje Emiru","Nidal Rifki","Mahmoud Meribout","Zhong Jing","Varun Tiwari","Mohamed Elkhalil"],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.22541/au.171386960.08601352/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21203/rs.3.rs-3722802/v1","name":"Large-area Magnetic Skin for Multi-point and Multi-scale Tactile Sensing with Super-resolution","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3722802/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-3722802/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.22541/au.172729884.48226389/v1","name":"A Comprehensive Approach to Intelligent Garment for Posture Correction: A Preliminary Study for Integrating Aesthetics and Sensor Interaction","source":"preprints","abstract":"","url":"https://doi.org/10.22541/au.172729884.48226389/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.22541/au.172729884.48226389/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21203/rs.3.rs-4173331/v1","name":"Vision-Based Tactile Sensors in Precision Agriculture: Deep Learning Approaches, Applications, and Limitations","source":"preprints","abstract":"Abstract The integration of artificial intelligence with sensor technologies has revolutionized precision agriculture, offering unprecedented opportunities for enhancing crop management and productivity.

By neglecting this aspect, valuable opportunities to enhance the accuracy and robustness of the fused data are missed. In contrast, biological systems often exhibit more efficient and synergistic sensor fusion mechanisms. Aquatic animals such as crayfish serve as remarkable models for multisensory integration, skillfully integrating visual, tactile, and chemical cues to evade predators, locate prey, and engage in mating behavior. Inspired by this, we propose a neuromorphic platform that integrates graphene-based chemitransistors, monolayer molybdenum disulfide (MoS2) based photosensitive memtransistors, and triboelectric tactile sensors to achieve “Super-Additive” responses to weak chemical, visual, and tactile cues and demonstrate contextual response modulation or adaptability, also referred to as “Inverse Effectiveness Effect”. Finally, we use a hypothetical illustration to highlight how crayfish-inspired sensor fusion approach can be transformative for autonomous search vehicles. We hold the view that the concept of bio-inspired sensor fusion can be extended to encompass various sensor modalities, thereby serving a wider array of applications.","url":"https://doi.org/10.21203/rs.3.rs-3261093/v1","authors":["Saptarshi Das","Najam U Sakib","Muhtasim Ul Karim Sadaf","Andrew Pannone","Subir Ghosh","Yikai Zheng","Harikrishnan Ravichandran"],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3261093/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.22541/au.172115142.24950097/v1","name":"From functional materials to artificial intelligence and flexible sensing","source":"preprints","abstract":"","url":"https://doi.org/10.22541/au.172115142.24950097/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.22541/au.172115142.24950097/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.21203/rs.3.rs-4738964/v1","name":"Novel miniaturized silicon-based capacitive six-axis force/torque sensor with large range, high sensitivity, and low crosstalk","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4738964/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4738964/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.22541/au.170708993.32664812/v1","name":"HapticFormers: Utilizing Transformers for Avocado Maturity Grading through Vision-based Tactile Assessment","source":"preprints","abstract":"","url":"https://doi.org/10.22541/au.170708993.32664812/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.22541/au.170708993.32664812/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2024.10.30.620429","name":"Touch to text: Spatiotemporal evolution of braille letter representations in blind readers","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.10.30.620429","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.10.30.620429","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.20944/preprints202404.0318.v1","name":"Sensors and Sensing Devices Utilizing Electrorheological Fluids and Magnetorheological Materials – a Review","source":"preprints","abstract":"","url":"https://doi.org/10.20944/preprints202404.0318.v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.20944/preprints202404.0318.v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.21203/rs.3.rs-4528779/v1","name":"A neuromorphic electronic artist for robotic painting","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4528779/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4528779/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21203/rs.3.rs-4867789/v1","name":"Biomimetic Freestanding Microfractals for Flexible Electronics","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4867789/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4867789/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21203/rs.3.rs-3261017/v1","name":"Tactile-GAT: Tactile Graph Attention Networks for Robot Tactile Perception Classification","source":"preprints","abstract":"Abstract As one of the most important senses in human beings, touch can also help robots better perceive and adapt to complex environmental information, improving their autonomous decision-making and execution capabilities. Compared to other perception methods, tactile perception needs to handle multi-channel tactile signals simultaneously, such as pressure, bending, temperature, and humidity. However, directly transferring deep learning algorithms that work well on temporal signals to tactile signal tasks does not make good use of the physical spatial connectivity information of tactile sensors. In this paper, we propose a tactile perception framework based on graph attention networks, which incorporates explicit and latent relation graphs. This framework can effectively utilize the structural information between different tactile signal channels. We constructed a tactile glove and collected a dataset of pressure and bending tactile signals during grasping and holding objects. And our method achieved 89.58% accuracy in object tactile signal classification with a small parameter size of 0.11M. Compared to existing time-series signal classification algorithms, our graph-based tactile perception algorithm can utilize and learn sensor spatial information, making it more suitable for processing multi-channel tactile data. Our method can serve as a general strategy to improve robot's tactile perception capabilities.","url":"https://doi.org/10.21203/rs.3.rs-3261017/v1","authors":["Lun Chen","Yingzhao Zhu"],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3261017/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:54.477Z"},{"id":"doi:10.21203/rs.3.rs-3053818/v1","name":"Ultrasensitive touch sensor for simultaneous tactile and slip sensing","source":"preprints","abstract":"Abstract Touch is a general term to describe mechanical stimuli. It is extremely difficult to develop touch sensors that can detect different modes of contact forces due to their low sensitivity. A high sensitivity response to complex contact states, such as pressure and slip, requires effective material design strategies for the sensor sensitivity layers. In this work, an ultrasensitive piezoresistive touch sensor is developed using a one-step phase-inversion-to-film strategy along with the sacrificial template method. The spectral analysis of the output signal is performed using a wavelet transform. This enables the sensor to be used for normal pressure and slip sensing. This work confirms that an interconnected porous structure can be easily controlled using this strategy. The sensor shows an ultra-high sensitivity of 1167 kPa − 1 and a low-pressure detection limit of 1.34 Pa due to its considerably low compression modulus of 23.8 Pa. A wavelet transform is used to successfully detect different contact states and identify various materials. This novel fabrication strategy and signal analysis method provides a new direction for the development of tactile/slip sensors.","url":"https://doi.org/10.21203/rs.3.rs-3053818/v1","authors":["Caofeng Pan","Yue Liu","Juan Tao","Yepei Mo","Rongrong

and face somatotopy shown using MRI-safe vibrotactile stimulation with a novel Soft Pneumatic Actuator (SPA)-Skin interface","source":"preprints","abstract":"The exact somatotopy of the human facial representation in the primary somatosensory cortex (S1) remains debated. One reason that progress has been hampered is due to the methodological challenge of how to apply automated vibrotactile stimuli to face areas in a manner that is: 1) reliable despite differences in the curvatures of face locations; and 2) MR-compatible and free of MR-interference artefacts when applied in the MR head-coil. Here we overcome this challenge by using soft pneumatic actuator (SPA) technology. SPAs are made of a soft silicon material and can be in- or deflated by means of airflow, have a small diameter, and are flexible in structure, enabling good skin contact even on curved body surfaces (as on the face). To validate our approach, we first mapped the well-characterised S1 finger layout using this novel device and confirmed that tactile stimulation of the fingers elicited characteristic somatotopic finger activations in S1. We then used the device to automatically and systematically deliver somatosensory stimulation to different face locations. We found that the forehead representation was least distant from the representation of the hand. Within the face representation, we found that the lip representation is most distant from the forehead representation, with the chin represented in between. Together, our results demonstrate that this novel MR compatible device produces robust and clear somatotopic representational patterns using vibrotactile stimulation through SPA-technology.","url":"https://doi.org/10.1101/2021.10.27.465604","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.1101/2021.10.27.465604","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.26434/chemrxiv.13271750.v1","name":"Piezoelectricity

body-representation through non-naturalistic sounds: study protocol for an experimental study in a subclinical eating disorders sample","source":"preprints","abstract":"Background: Experimental research based on bodily illusions suggests that people with eating disorders (EDs) might have impairments in visual, interoceptive, proprioceptive, and tactile perception, potentially underpinning altered multisensory integration processes. Along this line, research indicates that people with EDs show abnormalities in integrating multisensory visuo-tactile signals, which might contribute to the development of body image disturbances in EDs. More recently, an altered integration of auditory signals related to body weight has been also shown for people with EDs. However, it remains unclear whether these impairments extend to any auditory signals, even if not related to body weight. To fill the gap, the present study will investigate whether participants with ED symptomatology and control participants differ in two auditory feedback tasks which will involve integration of auditory and proprioceptive cues using artificial non-naturalistic sounds. We will test two different body parts (i.e., fingers and waist) which have different levels of emotional saliency for people with EDs. Methods Recruitment will be through convenience sampling. The EDE-Q questionnaire will be administered as a screening tool to split the sample into participants with and without ED symptomatology. The strength of both illusions will be measured implicitly with estimations of body part position and size, and explicitly with self-report questionnaires. As a secondary aim, regression analysis will be carried out to test the predictive role of susceptibility for both illusions on ED symptomatology, interoceptive body awareness and sensory-processing sensitivity. Discussion Our study might contribute to our understanding of the aetiology of body image disturbances. The results may lay the ground for novel clinical interventions which aim to improve symptoms at the early stages of the illness.","url":"https://doi.org/10.21203/rs.3.rs-1915001/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-1915001/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1101/2024.12.05.627113","name":"Universal rhythmic architecture uncovers distinct modes of neural dynamics","source":"preprints","abstract":"Understanding the organizing principles of brain activity can advance neurotechnology and medical diagnosis. Traditionally, brain activity has been viewed as consisting electrical field potentials oscillating at different frequency bands. However, emerging evidence suggests these oscillations can manifest as transient bursts rather than sustained rhythms. Here, we examine the hypothesis that rhythmicity (sustained vs. bursty) adds an additional dimension to brain organization. We segment neurophysiological spectra from 859 participants encompassing a dozen datasets across multiple species, recording techniques, ages 18-88, sexes, brain regions, and cognitive states in health and disease using a novel rhythmicity measure. Combined with simulations and brain stimulation, our results reveal a universal spectral architecture with two categories: high-rhythmicity bands exhibiting sustained oscillations and novel low-rhythmicity bands dominated by brief bursts. This universal architecture reflects stable modes of brain operation: sustained bands suitable for maintaining ongoing activity, and transient bands which can signal responses to change. Rhythmicity thus provides a powerful, replicable, and accessible feature-set for neurotechnology and diagnosis.","url":"https://doi.org/10.1101/2024.12.05.627113","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.12.05.627113","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.21203/rs.3.rs-3385988/v1","name":"Informing existing Technology Acceptance Models: A qualitative Study with older Persons and Caregivers","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3385988/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3385988/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1101/2020.05.29.20114199","name":"Effect of Dry Heat and Autoclave Decontamination Cycles on N95 FFRs","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2020.05.29.20114199","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.1101/2020.05.29.20114199","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2021.11.10.468144","name":"Learning enhances behaviorally relevant representations in apical dendrites","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2021.11.10.468144","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.1101/2021.11.10.468144","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2023.11.14.23298442","name":"The effects of inhaled corticosteroids on healthy airways","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2023.11.14.23298442","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1101/2023.11.14.23298442","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2024.03.21.586078","name":"Cell class-specific long-range axonal projections of neurons in mouse whisker-related somatosensory cortices","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.03.21.586078","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.03.21.586078","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2023.03.27.534406","name":"A dynamic neural resource model bridges sensory and working memory","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2023.03.27.534406","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1101/2023.03.27.534406","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21203/rs.3.rs-151919/v1","name":"Willingness to Use a Wearable Device Capable of Detecting and Reversing Overdose Among People Who Use Opioids in Philadelphia","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-151919/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.21203/rs.3.rs-151919/v1","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1101/2022.05.06.490864","name":"Single neurons and networks in the claustrum integrate input from widespread cortical sources","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2022.05.06.490864","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.1101/2022.05.06.490864","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1101/2020.04.16.044941","name":"Functional MRI of large scale activity in behaving mice","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2020.04.16.044941","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.1101/2020.04.16.044941","addedAt":"2026-08-31T06:34:47.155Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.1108/sr-01-2023-0009","name":"Interdigital flexible tactile sensor based on Velostat","source":"crossref","abstract":"Purpose Tactile sensation is an important sensory function for robots in contact with the external environment. To better acquire tactile information about objects, this paper aims to propose a three-layer structure of the interdigital flexible tactile sensor. Design/methodology/approach The sensor consists of a bottom electrode layer, a middle pressure-sensitive layer and a top indenter layer. First, the pressure sensitive material, structure design, fabrication process and circuit design of the sensor are introduced. Then, the calibration and performance test of the designed sensor is carried out. Four functions are used to fit and calibrate the relationship between the output voltage of the sensor and the contact force. Finally, the contact force sensing test of different weight objects and the flexible test of the sensor are carried out. Findings The performance test results show that the sensitivity of the sensor is 0.93 V/N when it is loaded with 0–3 N and 0.23 V/N when it is loaded with 3–5 N. It shows good repeatability, and the cross-interference between the sensing units is generally low. The contact force sensing test results of different weight objects show that the proposed sensor performs well in contact force. Each part of the sensor is a flexible material, allowing the sensor to achieve bending deformation, so that the sensor can better perceive the contact signs of the grasped object. Practical implications The sensor can paste the surface of the paper robot’s gripper to measure the contact force of the grasping object and estimate the contour of the object.

The indenter with three shapes of the prism, square cylinder and hemisphere is preliminarily designed and the prism indenter with better conduction force is selected through finite element analysis, which can concentrate the external force in the sensing area to improve the sensitivity. The sensor designed in this paper can realize the measurement of contact force, which provides a certain reference for the field of robot tactile.","url":"https://doi.org/10.1108/sr-01-2023-0009","authors":["Haifeng Fang","Yangyang Wei","Shuo Dong"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-07-31T02:36:58Z","doi":"10.1108/sr-01-2023-0009","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:54.477Z"},{"id":"doi:10.1007/978-3-642-59497-7_331","name":"A Tactile Sensor Instantaneously Evaluating Friction Coefficients","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-642-59497-7_331","authors":["Katsuhiko Nakamura","Hiroyuki Shinoda"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-12-27T07:09:42Z","doi":"10.1007/978-3-642-59497-7_331","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1108/02602280710723451","name":"High‐resolution tactile sensor using the deformation of a reflection image","source":"crossref","abstract":"Purpose The aim of this paper is to create a sensor that can measure the contact status with high‐resolution than ever.

Until now, the use of tactile sensor systems has been mostly based on sensing one modality of forces in the robotic end-effector. The use of a multi-modal tactile sensory system is motivated, which combines static and dynamic force sensor arrays together with an absolute force measurement system. This publication is focused on the development of a compact sensor interface for a fiber-optic sensor array, as optic measurement principles tend to have a bulky interface. Mechanical, electrical and software approaches are combined to realize an integrated structure that provides decentralized data pre-processing of the tactile measurements. Local behaviors are implemented using this setup to show the effectiveness of this approach.","url":"https://doi.org/10.3390/s140406854","authors":["Peter Kampmann","Frank Kirchner"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-04-16T11:39:38Z","doi":"10.3390/s140406854","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1108/02602280610675465","name":"Design and microfabrication of a hybrid piezoelectric‐capacitive tactile sensor","source":"crossref","abstract":"Purpose To measure the force applied to the tissue, the traditional endoscopic graspers might be equipped with a kind of tactile force sensor. Design/methodology/approach This paper presents the design, analysis, microfabrication and testing of a piezoelectric and capacitive endoscopic tactile sensor with four teeth. This tactile sensor, which is tooth‐like for safe grasping, comprises a Polyvinylidene Fluoride, PVDF film for high sensitivity and is silicon‐based for micromachinability. Being a hybrid sensor, employing both capacitive and piezoelectric techniques, it is possible to measure both the static and dynamic loads. Another feature, to be considered in its design, is the ability to detect pulse. The proposed sensor can be integrated with the tip of any current commercial endoscopic grasper without changing its original design. It is shown that using an array of sensor units, the position of the applied load can still be determined. Findings The static response of the sensor is obtained by applying a static force on the tooth and measuring the change in capacitance between the bottom electrode of the PVDF film and the electrode deposited on the surface of the etched cavity. The dynamic response of the device is determined by applying a sinusoidal force on the tooth of the sensor and measuring the output voltage from the PVDF film. The experimental results are compared with both analytical and finite element results. The sensor exhibits high sensitivity and linearity. Originality/value Capaciyive and piezoelectic are used to obtain both dynamic,pulse, and static loads.

Many tasks (e.g. parts identification) often give rise to situations which demand a more generalized methodology than the derivation of a single forward measurement, such as the computation of part area and perimeter from its run‐length‐coding representation. In this situation, an interpretation procedure generally adopts the techniques and methodology of a pattern recognition approach. To achieve maximum utility and flexibility, the methods used should be sensitive to any image change in size, translation and rotation, and should provide good repeatability. The algorithm used in this article generally meets these conditions. The results show that recognition schemes based on these invariants are position, size and orientation independent, and also flexible enough to learn most sets of parts. Assuming that parts can vary only in location, orientation and size, then certain moments are very convenient for normalization. For instance, the first moments of area give the centroid of a part, which is a natural origin of co‐ordinates for translation invariant measurements. Similarly, the eigenvectors of the matrix of second central moments define the directions of principal axes, which leads to rotation moment invariant measurements.","url":"https://doi.org/10.1108/eb007916","authors":["R.

We developed a novel type of soft resistive tactile sensor called a soft magnetic powdery sensor (soft-MPS) and evaluated its response characteristics. The soft-MPS comprises ferromagnetic powder that is immobilized in a liquid resin such as polydimethylsiloxane (PDMS) after orienting in a magnetic field. On applying an external force to the sensor, the relative distance between particles changes, thereby affecting its resistance. Since the ferromagnetic powders are in contact from the initial state, they have the ability to detect small contact forces compared to conventional resistive sensors in which the conductive powder is dispersed in a flexible material. The sensor unit can be made in any shape by controlling the layout of the magnetic field. Soft-MPSs with different hardnesses that could detect small forces were fabricated. The soft-MPS could be applied to detect collisions in robot hands/arms or in ultra-sensitive touchscreen devices.","url":"https://doi.org/10.3390/s19122677","authors":["Shunsuke Nagahama","Kayo Migita","Shigeki Sugano"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-06-13T11:15:58Z","doi":"10.3390/s19122677","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1007/978-3-8348-9777-0_6","name":"Vibro-Tactile Articulation and Presentation","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-8348-9777-0_6","authors":["Andreas Riener"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2011-06-06T19:02:10Z","doi":"10.1007/978-3-8348-9777-0_6","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1021/acsanm.4c04527.s007","name":"Multifunctional Flexible Sensor Based on Cracked Laser-Induced Graphene for Tactile Perception and Self-Healable Applications","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsanm.4c04527.s007","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-23T06:50:33Z","doi":"10.1021/acsanm.4c04527.s007","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1016/0736-5845(90)90063-e","name":"Flat tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1016/0736-5845(90)90063-e","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2009-09-23T12:49:05Z","doi":"10.1016/0736-5845(90)90063-e","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1021/acsami.2c21241.s006","name":"Wide Range Strain Distributions on the Electrode for Highly Sensitive Flexible Tactile Sensor with Low Hysteresis","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsami.2c21241.s006","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-03-21T07:11:14Z","doi":"10.1021/acsami.2c21241.s006","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1109/icsyse.1991.161133","name":"Object imaging with a multiplexed piezoelectric polymer tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icsyse.1991.161133","authors":["Kolesar","Reston","Ford","Fitch"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2002-12-09T18:24:26Z","doi":"10.1109/icsyse.1991.161133","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1109/ultsym.1991.234179","name":"A tactile sensor for the determination of object positions","source":"crossref","abstract":"","url":"https://doi.org/10.1109/ultsym.1991.234179","authors":["W.-s.

In previous studies, capacitive tactile sensors generally had an air gap between two electrodes in order to enhance the sensitivity. In this study, there is only polyurethane thin film and no air gap between the electrodes. The sensitivity of this sensor is higher than the previous capacitive tactile sensors because the polyurethane is a fairly flexible elastomer and the film is very thin (about 1 µm). The polyurethane film is formed by spin-coating and etched back from 6 µm to 1 µm using 48% sulfuric acid. As a result of evaluation, the sensitivity of the developed sensor (diameter is 1 mm) is 1.3 pF/Pa (800 pF/N considering the sensing area).

This study presents a flexible sensor array based on eutectic gallium‐indium (EGaIn) liquid metal microchannels, which enables high‐fidelity shape reconstruction through a combined theoretical and algorithmic framework. We establish a resistance‐sum model integrated with a bipartite graph mapping to theoretically analyze and guarantee uniqueness in pressure localization. Experimental and simulation results demonstrate that single‐point and continuous multi‐point pressures can be uniquely localized, whereas discrete distributions may exhibit ambiguity when pressure points lack row or column continuity, such as in cross‐row or cross‐column patterns, due to multiple equivalent edge sets in the bipartite graph. Furthermore, we develop a threshold‐based reconstruction method that significantly enhances the restoration of complex morphologies, including squares, square rings, and circles. This work provides a robust foundation for high‐fidelity shape reconstruction in flexible tactile sensing practices.","url":"https://doi.org/10.1002/adsr.202500170","authors":["Qi Zhang","Yujia Song","Nan Li","Changlin Liu","Chen Wang","Jing Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-01-22T09:26:03Z","doi":"10.1002/adsr.202500170","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/robot.1987.1087915","name":"Performance analysis of a tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1987.1087915","authors":["D.

The paper describes the related research work we have developed for sensor design, exploration and control for a robot gripping system, in order to analyze normal forces applied on the tactile pixels for gripping force control and generate tactile images for gripping positioning and object recognition. Section 1 gives an introduction of principles and technologies in tactile sensing for robot grippers. Section 2 presents the sensor cell (taxel) and array design and characterization. Section 3 introduces object recognition and shape analysis ideas showing a few preliminary examples, where geometrical features of small objects are identified. Slip detection in order to define optimum grasp pressure is addressed in section 4.

Design/methodology/approach The sensor array consists of a sandwich structure. Sensing elements are distributed discretely in the sensor. Each sensing element has two electrodes and a piece of conductive rubber with piezoresistive property. The electrodes, as well as the conductive trace for signal transmission, are printed on the substrate layer by the screen printing technique. A scanning circuit based on zero potential method and an experimental set‐up based on balance to characterize the sensor array are designed and implemented in the test of the sensor array. Findings Experimental results verify the validity of the sensor array in measuring the vertical tactile force between the sensing elements and the object. Research limitations/implications In this paper, all the sensors are tested without calibration procedures and the procedure of the dynamic test is implemented by manual operation. Practical implications The sensor array could be applied to measure the plantar force for gait detection in clinical applications. Originality/value The paper presents a tactile force sensor array with discrete sensing elements to essentially restrict the cross‐talk among sensing elements. This paper will provide many practical details that can help others in the field.","url":"https://doi.org/10.1108/02602281211257506","authors":["Xuefeng Zhang","Yulong Zhao","Xuelei Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2012-09-06T11:41:38Z","doi":"10.1108/02602281211257506","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:54.477Z"},{"id":"doi:10.18260/1-2--60211","name":"Nanotechnology and Electronic Sensor Education Through a Research Project on Graphene-based Tactile Sensors","source":"crossref","abstract":"","url":"https://doi.org/10.18260/1-2--60211","authors":["Sandip Das"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-21T14:49:31Z","doi":"10.18260/1-2--60211","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1142/9781848163539_0034","name":"DEVELOPMENT OF A TACTILE SENSOR FOR EVALUATION OF DETERGENTS","source":"crossref","abstract":"","url":"https://doi.org/10.1142/9781848163539_0034","authors":["DAISUKE TSUCHIMI","MAMI TANAKA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-03-17T07:43:22Z","doi":"10.1142/9781848163539_0034","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.4028/www.scientific.net/amr.744.501","name":"Robot Soft Grabbing with New Piezoresistive Tactile Sensor","source":"crossref","abstract":"A type of tactile sensors based on piezoresistive principle is designed for the robot grab force detection and control.

Furthermore, the practicality of our proposed method is validated by integrating two calibrated flexible tactile sensors (each with a 100 cm2 area) into a robot arm platform.","url":"https://doi.org/10.36227/techrxiv.23295356.v1","authors":["Haofeng Chen","xuanxuan yang","Gang Ma","Xiaojie Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-06-07T10:08:20Z","doi":"10.36227/techrxiv.23295356.v1","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1021/acsaelm.4c00841.s001","name":"Screen-Printed Capacitive Tactile Sensor for Monitoring ToolTissue Interactions and Grasping Performances of a Surgical Magnetic Microgripper","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsaelm.4c00841.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-31T10:10:25Z","doi":"10.1021/acsaelm.4c00841.s001","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1109/icsens.2009.5398268","name":"Slippage degree estimation for dexterous handling of vision-based tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icsens.2009.5398268","authors":["Yuji Ito","YoungWoo Kim","Goro Obinata"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2010-01-26T17:37:14Z","doi":"10.1109/icsens.2009.5398268","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1088/1361-665x/ad884b/v1/decision1","name":"Decision letter for \"Simulation and theory for wiring compaction of robot skin tactile sensor by frequency-selective triboelectric-piezoelectric filters\"","source":"crossref","abstract":"","url":"https://doi.org/10.1088/1361-665x/ad884b/v1/decision1","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-18T17:14:44Z","doi":"10.1088/1361-665x/ad884b/v1/decision1","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1007/978-981-10-5230-9_34","name":"A Stable and Efficient Vision-Based Tactile Sensor with Tactile Detection Using Neural Network","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-981-10-5230-9_34","authors":["Chao Yang","Fuchun Sun","Bin Fang","Luxuan Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-07-09T22:54:05Z","doi":"10.1007/978-981-10-5230-9_34","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1109/transducers.2019.8808306","name":"Integration of Stainless-Steel Tactile Bump with Inductive Tactile Sensor Array for 3D Micro Joystick Button Application","source":"crossref","abstract":"","url":"https://doi.org/10.1109/transducers.2019.8808306","authors":["Sheng-Kai Yeh","Weileun Fang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-08-22T23:48:15Z","doi":"10.1109/transducers.2019.8808306","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1088/1361-6501/acf32f","name":"Design and tactile classification of flexible tactile sensor for soft gripper","source":"crossref","abstract":"Abstract Tactile object recognition is very important in robot sorting and handling system. The existing researches on tactile recognition mainly focus on rigid grippers, which cannot be directly applied to soft grippers with better safety and applicability. In this paper, a tactile sensor for soft gripper is proposed. The tactile sensor consists of a carbon composite Velostat and a flexible printed circuit designed for soft gripper. The sensor is equipped with signal scanning, amplifying and processing systems. A number of performance tests were carried out on the designed tactile sensor to prove that it has good performance in sensing sensitivity, loading stability, repeatability. In addition, tactile sensors are applied to tactile classification. The two fingers of the flexible gripper were loaded with a sensor and nine different objects were contacted. The tactile information of the objects was obtained through the stable gripper, and the tactile data was trained and classified by the support vector machine. Finally, the tactile recognition accuracy of the double-exponent data was 91.1%.","url":"https://doi.org/10.1088/1361-6501/acf32f","authors":["Shuo Dong","Lihua Cai","Yangyang Wei","Jianguo She"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-08-23T18:24:36Z","doi":"10.1088/1361-6501/acf32f","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1016/j.snb.2013.06.050","name":"Slime mould tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.snb.2013.06.050","authors":["Andrew Adamatzky"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2013-06-25T09:53:49Z","doi":"10.1016/j.snb.2013.06.050","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1109/jsen.2025.3575359/mm3","name":"A stretchable tactile sensor array based on hydrogel ionic diodes_supp3-3575359.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/jsen.2025.3575359/mm3","authors":["Xinyu Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-04T13:52:30Z","doi":"10.1109/jsen.2025.3575359/mm3","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1017/s0263574700006664","name":"A novel tactile sensor for robot applications","source":"crossref","abstract":"SUMMARY This paper examines a tactile slip sensor based on photoelastic effects.

This paper reports on a new optical tactile sensor based on multiple scattering in a porous material with a viscoelastic phase-separated structure fabricated by a sol-gel method. When a macroporous silicone monolith with a few micrometer diameter skeletons was compressed, the diffuse light intensity near the light source was reduced due to Mie multiple scattering. A simple tactile sensor using a macroporous monolith and a photo reflector was fabricated based on this finding. The skeleton diameter was an important factor for the sensor. In the case of macroporous silicones, the voltage-strain curve showed an almost hysteresis-free clear response. However, the response of macroporous polymethylmethacrylate monolith with a smaller skeleton diameter was weak due to low Mie scattering intensity. Using cell structure materials with a scale much larger than the optical wavelength, a decrease in light intensity with compression was not observed. Sensors using sol-gel-derived flexible macroporous monoliths could provide features such as thinness and improved surface tactility.","url":"https://doi.org/10.26434/chemrxiv-2022-r5kct","authors":["Gen Hayase"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-05-19T01:45:58Z","doi":"10.26434/chemrxiv-2022-r5kct","addedAt":"2026-08-31T06:34:47.881Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1109/robot.1993.292019","name":"A tactile sensor using three-dimensional structure","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1993.292019","authors":["H.

It is believed that humans can promptly discern slip and consequently modify grip forces to prevent complete loss of grasp. This paper analyzes and validates two incipient slip detection methods using force and displacement signals from the PapillArray tactile sensor, detecting slip on some of the sensors’ pillars before gross slip occurs. A major contribution of this paper is the development of a novel algorithm that can detect slip caused by either translational or rotational movement of the object relative to the sensor, where previous algorithms were not designed to work for slip caused by rotation. Slip events were independently verified using external camera tracking and subsequently used to evaluate slip detection algorithms operating solely on the PapillArray force and displacement signals. Several algorithm parameters influencing algorithm performance were explored with the goal of optimizing slip detection accuracy. The new algorithm, which can also detect slip for rotational tests, was successful in recognizing slip occurrences using PapillArray data (precision of 85% and recall of 90%), and in detecting incipient slip before gross slip occurs across a range of velocities of translational and rotational movements. Future work will test the algorithms’ effectiveness in real-world object manipulation.

This study aims to establish how doping PZT with Strontium will result in PSZT thin films with improved piezoelectric properties for biomedical tactile sensor applications. Various thin film samples were fabricated via sol-gel &amp; spin-coating processing methods-PZT (4 layers), PSZT (4 layers), PSZT-PZT (2L PSZT base-2L PZT) and PZT-PSZT (2L PZT base-2L PSZT), analyzed by X-Ray Diffraction (XRD) and Atomic Force Microscopy (AFM) to determine crystalline structure and surface morphology, and by a ferroelectric analyzer to determine leakage current characteristics and ferroelectric parameters such as P max , P r and V c (representation of piezoelectric properties). The addition of Strontium retains the perovskite structure of PZT and marginally influences the ferroelectric properties. Among the hybrid films, PZT(base)-PSZT showed better ferroelectric characteristics (higher P max and P r values). A mathematical relationship between the ferroelectric parameters (P r and V c ) to evaluate the films quality factor in relation to their application as tactile sensors, was also established, from which it was concluded that PZT-PSZT performs much better than the other 3 films for such applications despite high V c values. The improved performance of hybrids may be due to the evolved microstructure and crystalline structure. Present investigation resulted in two important conclusions: PZT-PSZT hybrid films are ideal for tactile sensor applications, and the mathematical relationship developed can be used to evaluate any piezoelectric/ferroelectric materials.","url":"https://doi.org/10.4028/www.scientific.net/ssp.185.65","authors":["V.S.

Integration oftactile feedback via electrotactile stimulation on the residual limb improved SHAP functional scores by 18.4% (p = 0.002)and reduced object drop rate from 24.6% to 8.2% (p < 0.001).

In this study, a custom-built wheeled bimanual robotic platform equipped with an exoskeleton-style teleoperation system was utilized to realize intuitive remote manipulation and the efficient collection of anthropomorphic action data. To overcome the representation mismatch between spatial visual semantics and localized high-frequency physical dynamics, we propose a lightweight frequency-aligned imitation-learning framework, termed the Frequency-Enhanced Wavelet-based Transformer (FEWT). FEWT integrates two primary modules: Frequency-Enhanced Efficient Multi-Scale Attention (FE-EMA) and Time-Series Discrete Wavelet Transform (TS-DWT) to explicitly extract and align multi-scale features, improving the compatibility between spatial visual representations and temporal-frequency recalibration. Crucially, for real-world deployment, this framework is further extended into a multimodal system by seamlessly integrating a self-developed Smart Tactile Fabric (STF) sensor into the physical end-effectors, providing local contact-stress information that complements proprioceptive and chassis-motion cues in the shared multimodal representation. Experimental evaluations demonstrate that the core FEWT architecture significantly improves the success rate over the widely used Action Chunking with Transformers baseline, particularly during the most challenging phases of simulated bimanual insertion tasks. Furthermore, in complex real-world mobile and desktop manipulation tasks, the full STF-enhanced system effectively adapts to microscopic dynamic perturbations, yielding substantial performance enhancements.","url":"https://doi.org/10.48550/arxiv.2509.11109","authors":["Huang, Jiaxin","Liu, Hanyu","Ma, Yunsheng","Shen, Jian","Zheng, Yilin","Wen, Jiayi","Song, Zhigong"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2509.11109","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.26083/tuda-8176","name":"Magnetic Composites for Soft Robotics","source":"datacite","abstract":"Magnetic soft robotics offers a promising route to lightweight, untethered systems capable of complex and adaptive motion. This cumulative dissertation investigates how magnetic soft robotics can be advanced by co-designing materials, architecture, and sustainability from the ground up. It brings together three main contributions: (i) bioinspired morphing structures with large and adaptive deformations, (ii) muscle-inspired magnetic actuators with multifunctionality, and (iii) environmentally sustainable, recyclable magnetic composites for actuation and sensing. First, architected magnetic butterfly wings are fabricated from a thermoplastic polyurethane TPU/Nd-Fe-B composite using laser powder bed fusion (LPBF). The wings incorporate sub-millimeter flexural hinges, graded membrane regions, and pre-programmed magnetization patterns. Experiments and finite-element modelling show that large-angle folding, upstroke wing-clapping, and multistable morphing can be encoded purely through geometry and magnetization, without discrete joints or multi-material assemblies. Second, the same LPBF TPU/Nd-Fe-B platform is extended to muscle-inspired actuators that realize contraction-dominated motion. Zig-zag hinge architectures and radially expandable geometries are designed to shorten axially, lift loads many times their own weight, and perform gripping and anchoring tasks under low magnetic fields. By magnetizing pre-deformed structures, magnetization patterns are imprinted, enabling large reversible contractions and multifunctionality (load lifting, use in a crawling robot, and in-tube anchoring) within a single monolithic body. Third, the thesis introduces a sustainable magnetoactive material system based on recycled Nd-Fe-B microparticles embedded in a gelatin-glycerol/1,3-propanediol organogel. The composite combines high stretchability with robust magnetic response and is processed into thin-film robots and magnetoelastic sensing patches. Two closed-loop recycling routes are demonstrated: solvent-assisted matrix dissolution with magnetic particle recovery, and thermal remolding of composite fragments. Magnetic hysteresis measurements confirm that remanence and coercivity of the recycled particles remain largely stable over multiple cycles. Soft “flippy” and worm-like robots, as well as tactile and proximity sensors using pick-up coils and planar Hall sensors, show that meaningful robotic and sensing functions can be realized in a degradable, recyclable material framework. Across these three platforms, the dissertation establishes a coherent design philosophy: behaviour in magnetic soft robots can be programmed through the interplay of material constitution, architecture, and magnetization profile, while also addressing sustainability. Architected LPBF composites deliver optimal morphing and contraction, and gelatin-based organogels demonstrate that soft robotic functionalities can be embedded in circular material systems. Together, the results position this thesis for a new class of magnetic soft machines that are adaptive in form, capable in function, and responsible in their use of resources.","url":"https://doi.org/10.26083/tuda-8176","authors":["Khan, Muhammad Bilal"],"tags":["620"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.26083/tuda-8176","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.7892/boris.50501","name":"Introduction of two novel devices for investigating the influence of non-mechanical components such as therapeutic qi in acupuncture","source":"datacite","abstract":"OBJECTIVE: Acupuncture is a complex intervention consisting of specific and non-specific components. Acupuncture studies more frequently focus on collecting data from the patients’ perspective and response, but the acupuncturist’s role remains relatively unclear. In order to investigate potential non-mechanical active factors originating from the acupuncturist and transmitted to the patient during treatment, two novel devices for basic research in acupuncture were designed. The Acuplicator allows the researcher to insert needles without touching the needles themselves, while the Veliusator locks the needle in its place so that no mechanical movement can be transferred. METHODS: The Acuplicator was used to insert needles at Neiguan (PC6) on the right forearm of 23 volunteers. The insertion depth was measured using a depth gauge. The transfer of mechanical movements from the handle to the tip was detected with a precision length gauge with a motoric-tactile sensor. RESULTS: The mean insertion depth was (12.3 ± 1.5) mm (range 9.5 to 15.0 mm). Even with intense manipulation of the needle handle, no movements within ± 1 μm could be detected at the tip when the needle was locked. CONCLUSION: With these two devices it will be possible to investigate the influence of non-mechanical components such as therapeutic qi in acupuncture.","url":"https://doi.org/10.7892/boris.50501","authors":["Hochstrasser, Raphael J.","Endler, Christian P.","Klein, Sabine"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2013","doi":"10.7892/boris.50501","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.48620/88567","name":"Vertical Reflection Intensity, Roughness, and Tactile Sensation of Caries-Inactive, Caries-Active and Sound Enamel Surfaces: An In Vitro Study.","source":"datacite","abstract":"Objectives This study evaluated whether reflection intensity, roughness and tactile sensation differs between caries-inactive, caries-active and sound enamel surfaces.Methods Pooled permanent teeth were assessed using surface texture and color.

However, prior vision-based pressure estimation methods are largely limited to planar surfaces and single image input, making them difficult to apply to dynamic hand-object interaction with diverse objects. We instead formulate pressure estimation as a hand-centric video prediction problem with monocular video as input. This formulation predicts temporally evolving per-vertex normal pressure and contact directly on the hand mesh, yielding a unified output space independent of object shape and sensor layout. Building on this formulation, we propose \\textbf{HOPE}, a framework with two key components. First, we lift tactile-glove pressure, planar-sensor pressure, and distance-based hand-object contact annotations into a shared hand vertex space, allowing bare-hand contact data to regularize pressure learning where metric labels are unavailable. Second, we introduce a vertex-anchored video transformer that treats each vertex as a persistent token, aggregates visual features and hand pose over time, and uses a contact-gated pressure head to enforce that pressure vanishes without contact. Experiments on OpenTouch, PressureVisionDB, and hand-object contact benchmarks validate HOPE across object-pressure, surface-pressure, and contact-supervised HOI settings.

However, the large sim-to-real gap of tactile sensors prevents robots from acquiring useful tactile-based manipulation skills from simulation data, a recipe that has been successful for achieving complex and sophisticated control policies. Prior work has implemented binarization techniques to bridge the sim-to-real gap for dexterous in-hand manipulation. However, binarization inherently loses much information that is useful in many other tasks, e.g., insertion. In our work, we propose GCS, a novel sim-to-real technique to learn contact-rich skills with dense, distributed, 3-axis tactile readings.

They can either be wheeled, tracked or legged. In this thesis we will focus on n-wheeled vehicles able to perform ground following motion with all the wheels maintaining contact at the same time. The main goal of this work is to establish the implication of the topological architecture of the vehicle mechanism on criteria such as climbing skills, robustness, ground clearance, weight, power consumption, and price. Efficient tools will be provided to help the robot designer to understand the implications of important design parameters like the number of wheels, the vehicle mechanism, and the motorisation of joints on the above criteria. The general state of a robotic ground vehicle can be described using spatial vectors containing both the linear and angular components of physical quantities such as position, velocity, acceleration and linear force. By definition, there is motion when the vehicle's link velocity state vector (expressed from the ground reference) is greater than zero. Wheeled ground following motion is then a special case of vehicle constrained motion where all wheels maintain contact with the ground. This thesis will describe a general kinematic and dynamic analysis of n-wheeled ground following robots. We will then discuss \"contact forces optimisation techniques\" and show the relationship between the number of wheels of a vehicle mechanism, the topological structure and the optimised degrees of fredom that we can get for the contact forces distribution. We will conclude with some considerations concerning the sensors needs for on-board terrain estimation. We will emphasise our argument using our two robot designs as examples: Shrimp: A 6-wheeled ground vehicle based on a 3 DOF passive suspension mechanism. With this design, no sensor based control is necessary to maintain ground contact with all the wheels. The distribution of tangential contact forces is done passively but can be optimised with on board active control and sensors for contact properties estimation (gyro, joint position sensors). Octopus: A 8-wheeled ground vehicle based on a (6 DOF active + 1 DOF passive) suspension mechanism. The autonomous coordination of the active 14 DOF is based on the on-board integration of inclinometer, joint position sensors and tactile wheels able to sense ground contact properties (angle, curvature, force, ...). With this design, active control can distribute the contact forces to minimise tangential forces and increase traction. This decreases the need for friction to climb obstacles. The theoretical investigation and new sensing concepts enable the design these two robots that demonstrate excellent capabilities for rough terrain. Passive Wheeled Locomotion Mechanisms (WLM) solutions are now mature enough for real applications like space exploration. However, active WLM solutions demonstrate potential climbing skills that cannot be equalled passively. Enhanced integration of sensors, actuators and advanced embedded control algorithms will lead to greater applications for future field and service robotics applications.","url":"https://doi.org/10.5075/epfl-thesis-2833","authors":["Lauria, Michel"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2003","doi":"10.5075/epfl-thesis-2833","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.48550/arxiv.2608.04242","name":"Feasibility of Embedded Photoplethysmography Sensing in Short-Duration Tactile Interactions With Pocket-Sized Robots Using IMU- and Confidence-Based Filtering","source":"datacite","abstract":"Ubiquitous companion robots offer a promising avenue for immediate anxiety relief in children, yet their effectiveness relies on the ability to monitor physiological states continuously and unobtrusively.

We address the significant challenge of motion artifacts inherent in handheld usage by implementing a two-stage filtering pipeline that utilizes an onboard Inertial Measurement Unit (IMU) to reject high-variance segments and a confidence-based smoothing algorithm for recovery periods.

Embedded electronic systems usually host sensors, and each sensor hosts multiple input channels (e.g., tactile, vision), tightly coupled to the electronic computing unit (ECU). The ECU extracts information by often employing sophisticated methods, e.g., Machine Learning. However, embedding Machine Learning algorithms poses essential challenges in terms of hardware resources and energy consumption because of: 1) the high amount of data to be processed; 2) computationally demanding methods. Leveraging on the trade-off between quality requirements versus computational complexity and time latency could reduce the system complexity without affecting the performance. The objectives of the thesis are to develop: 1) energy-efficient arithmetic circuits outperforming state of the art solutions for embedded machine learning algorithms, 2) an energy-efficient embedded electronic system for the ?electronic-skin? (e-skin) application. As such, this thesis exploits two main approaches: Approximate Computing: In recent years, the approximate computing paradigm became a significant major field of research since it is able to enhance the energy efficiency and performance of digital systems. ?Approximate Computing?(AC) turned out to be a practical approach to trade accuracy for better power, latency, and size . AC targets error-resilient applications and offers promising benefits by conserving some resources. Usually, approximate results are acceptable for many applications, e.g., tactile data processing,image processing , and data mining ; thus, it is highly recommended to take advantage of energy reduction with minimal variation in performance . In our work, we developed two approximate multipliers: 1) the first one is called ?META? multiplier and is based on the Error Tolerant Adder (ETA), 2) the second one is called ?Approximate Baugh-Wooley(BW)? multiplier where the approximations are implemented in the generation of the partial products. We showed that the proposed approximate arithmetic circuits could achieve a relevant reduction in power consumption and time delay around 80.4% and 24%, respectively, with respect to the exact BW multiplier. Next, to prove the feasibility of AC in real world applications, we explored the approximate multipliers on a case study as the e-skin application. The e-skin application is defined as multiple sensing components, including 1) structural materials, 2) signal processing, 3) data acquisition, and 4) data processing. Particularly, processing the originated data from the e-skin into low or high-level information is the main problem to be addressed by the embedded electronic system. Many studies have shown that Machine Learning is a promising approach in processing tactile data when classifying input touch modalities. In our work, we proposed a methodology for evaluating the behavior of the system when introducing approximate arithmetic circuits in the main stages (i.e., signal and data processing stages) of the system. Based on the proposed methodology, we first implemented the approximate multipliers on the low-pass Finite Impulse Response (FIR) filter in the signal processing stage of the application. We noticed that the FIR filter based on (Approx-BW) outperforms state of the art solutions, while respecting the tradeoff between accuracy and power consumption, with an SNR degradation of 1.39dB. Second, we implemented approximate adders and multipliers respectively into the Coordinate Rotational Digital Computer (CORDIC) and the Singular Value Decomposition (SVD) circuits; since CORDIC and SVD take a significant part of the computationally expensive Machine Learning algorithms employed in tactile data processing. We showed benefits of up to 21% and 19% in power reduction at the cost of less than 5% accuracy loss for CORDIC and SVD circuits when sc","url":"https://doi.org/10.15167/osta-mario_phd2020-02-27","authors":["OSTA, MARIO"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.15167/osta-mario_phd2020-02-27","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.5281/zenodo.20678587","name":"Compute-Aware Embodied Execution: How Temporal Asymmetry, Surrogate Sensing, Architecture-Matched Monitoring, Adaptive Routing, and Speed-Conditioned Control Jointly Constrain Real-Time Robot Deployment","source":"datacite","abstract":"Version 2 — revised in response to an external structural review and an automated critique pass. See \"Response to Review\" appendix in the PDF for the change log. Deploying robot policies in closed-loop, real-time settings imposes a set of constraints that are qualitatively different from those governing offline training: every millisecond of compute consumed is a millisecond of physical state that evolves without correction, every sensor absent from the hardware stack is a gradient of feedback permanently lost, and every safety monitor mismatched to the policy's internal architecture produces a false sense of assurance. This paper synthesises five specific findings from recent arXiv preprints across cs.RO, cs.HC, and eess.SY to argue a **candidate structural pattern**: real-time robot deployment is governed by a set of compute-feedback co-constraints that cannot be resolved independently—latency, sensing fidelity, monitoring architecture, temporal resolution, and execution speed must be co-designed rather than treated as separable engineering concerns. This is a **heuristic reading, not a derivation from a shared formal structure**; the five findings converge thematically rather than through a unified mathematical framework, and the analogy between them is asserted on the basis of shared vocabulary rather than proven at the level of mechanism. The corpus draws on: (1) adaptive test-time compute routing for embodied planners [corpus:arxiv:2606.12402]; (2) surrogate force estimation enabling contact-aware policy learning without dedicated hardware [corpus:arxiv:2606.12406]; (3) architecture-matched action monitoring revealing that failure signatures differ qualitatively across VLA families [corpus:arxiv:2605.28726]; (4) asynchronous temporal decoupling of world prediction from action execution [corpus:arxiv:2606.09811]; and (5) speed-conditioned trajectory augmentation enabling dynamic phase-aware execution [corpus:arxiv:2606.06491]. Supporting context is drawn from edge-SoC deployment constraints [corpus:arxiv:2606.07383], physics-grounded tactile representation for sim-to-real transfer [corpus:arxiv:2605.28812], and safety filtering grounded in VLA internal attention [corpus:arxiv:2606.09749]. All sources are preprints and have not undergone peer review; results should be treated accordingly. The primary falsification path is concrete: deploy a robot system in which compute routing, sensing surrogates, monitoring, temporal decoupling, and speed conditioning are each independently ablated in a controlled hardware experiment measuring task success, latency, and safety-critical collision rate. If ablating any single component does not degrade performance while the others remain intact, the co-design claim is falsified for that component. --- Authorship: Saluca Agentic AI Research Team (Saluca LLC).

In practice, visual feedback is indispensable, and tactile solutions that cannot coexist with vision are difficult to translate into RMIS tools. To address both needs, we introduce MVP-Tac, a compact, vision-based tactile sensor that provides co-located vision and tactile sensing. MVP-Tac uses reflective photoelastic imaging: a thin photoelastic elastomer produces stress-dependent interferograms under contact that are captured by an embedded camera through a miniaturized reflective polariscope. A semi-transparent membrane and controllable illumination enable switching between visual mode and tactile mode, enabling tactile perception without sacrificing vision. We validate MVP-Tac through force calibration in the 0 to 2 N range and demonstrate its potential for tumor palpation via video-based hardness classification on tissue phantoms, achieving 97% accuracy for exposed-tumor classification and 92% accuracy for subdermal-tumor classification. Finally, we conduct a simulated colonoscopy to validate both visual and tactile modalities in a constrained lumen, including vision-guided 3D photomapping of the luminal wall and in situ hardness classification of localized nodules. Overall, MVP-Tac provides a practical path toward restoring clinically useful palpation in RMIS while maintaining essential visual feedback.

Existing curved vision-based tactile sensors struggle to combine accurate 3D reconstruction, three-axis force estimation, and high-speed processing in a compact form. This article presents FasTac, a curved vision-based tactile sensor integrating multispectral photometric stereo, dynamic-convolution force estimation, and hardware acceleration on a field-programmable gate array (FPGA). Single-image-sensor simultaneous multispectral imaging provides spatially aligned observations for robust surface normal estimation, followed by boundary-prior fast Poisson depth reconstruction. HyperForce uses position-aware dynamic convolution to model the spatially nonuniform mechanical response of curved elastomers and estimate three-axis forces. The complete image-to-normal-force pipeline is deployed on an FPGA. Experiments show that near-infrared (NIR) illumination and the boundary prior decrease depth mean absolute error (MAE) from 0.2730 mm to 0.0415 mm; HyperForce achieves normalized mean absolute error (NMAE) values of 2.74% and 2.39% for normal and shear forces, respectively; and FPGA deployment shortens processing latency from 3.26 ms on the GPU to 1.09 ms.

Very little is known about the strategies that patients with CVA employ to prevent falls during unexpected changes of a support surface while patients are standing and walking. Previous studies showed that light touch increases postural stability in healthy subjects. However, it is not known whether patients with CVA would benefit from light touch in the same way as the healthy subjects do. Three studies in this research were conducted to examine the impact of stroke on postural responses triggered by surface rotations (Triggered Postural Responses; TPRs) during standing and walking and to investigate the effect of light touch on the control of TPRs during both tasks. Pitch and roll surface rotations (amplitude:5o; peak velocity:32o/s) were randomly presented to 11 stroke and 8 healthy age-matched subjects during quiet stance and walking, with similar limb geometry in double limb support. Light touch (&lt;4N) was provided by a load sensor strip mounted on a rail along the walkway. Body kinematics was captured at 120 Hz by a 6-camera Vicon 512 system. Ground reaction forces were acquired at 1080Hz by 2 AMTI force plates. Surface EMGs were recorded at 1080 Hz from 4 bilateral lower limb muscles. Results showed that TPRs in healthy subjects were functionally appropriate to the direction of perturbations and task demands, such that TPRs were tuned down during walking, as compared to standing, suggesting that postural requirements are less during walking. In contrast, CVA disrupts equilibrium control such that TPRs in the stroke subjects were delayed and not modulated as the perturbed directions and task demands changed, possibly due to problems in sensorimotor integration. Asymmetry was characterized by under-activated muscle responses and force generations of the paretic side and hyperactivity of the non-paretic upper and lower extremities. These impairments led to instability of the trunk and center of pressure, especially in the frontal plane. Light touch increased postural stability in both subjects but its effect was more dominant in the stroke subjects, suggesting that light touch is a potential tool for balance rehabilitation. \"@eng","url":"https://doi.org/10.82308/43107","authors":["Boonsinsukh, Rumpa"],"tags":["Rehabilitation and Therapy"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2003","doi":"10.82308/43107","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.82308/40881","name":"Tactile recovery of shape from texture deformation","source":"datacite","abstract":"As robots are developed to make life for humans easier, their ability to navigate and manipulate theenvironment around them is crucial for a great number of tasks.

Recently, much of research has focused on machine learning approaches to sensor data for delivering more intelligence into different health and fitness applications. However, there are different challenges associated with these approaches that limit us to reach an acceptable accuracy level. In this thesis, a comprehensive analysis of wearable accelerometer sensors in human activity recognition problem is conducted to address the classification issues while dealing with inter-person differences and data diversities. In addition, novel feature extraction and classification techniques are proposed to improve the accuracy as well as the worst-case sensitivity in the multi-class classification. The introduced techniques are experimentally validated by considering two state-of-the-art case studies. This work presents significant evidence that we can build accurate predictive models for sensor-based recognition and diagnostic problem under more realistic conditions. Furthermore, to reduce the computational costs of the decision-making process, an innovative algorithm is presented to analyze the variations in the periodic signals. It reduces the learning efforts by detecting any significant changes in the signals. There is also an increasing potential for integration of wearable sensors and haptic systems to improve human motion learning in a wide range of applications. Therefore, we investigate how real-time corrective feedback improves the user's performance in a health application.

Their ability to generate van der Waals forces without requiring external energy input makes them highly promising for robotic gripping applications. However, ensuring consistent adhesion, particularly on curved or irregular surfaces, necessitates precise contact formation. Even minor misalignments can lead to significant reductions in adhesion strength, impacting the reliability of gripping mechanisms. The effectiveness of these adhesives is largely influenced by their mechanical properties, which are often not explicitly available in standard material datasheets. As a result, accurate modeling of their mechanical response remains a key challenge. This thesis addresses the problem of material parameter estimation for finite element modeling (FEM) of a soft tactile sensor integrated with bioinspired adhesives. A key objective is to bridge the gap between simulated and experimental sensor responses, ensuring that the numerical models accurately replicate real-world behavior. Bayesian optimization is employed to determine the optimal Young’s modulus and Poisson’s ratio of the sensor’s foam layer by minimizing the error between simulated and experimental displacement data. This optimization ensures that the simulated deformations closely match physical measurements, enhancing the predictive reliability of the FEM model. Additionally, machine learning models are developed to predict the contact area and classify object shapes based on sensor displacement values, enhancing the interpretability of sensor responses in robotic applications. To achieve this, a dataset of simulated sensor responses is generated through FEM, and Bayesian optimization is used to iteratively refine material properties to achieve realistic displacement predictions. The optimized model serves as a foundation for generating synthetic datasets, reducing the dependency on labor-intensive experimental data collection.The resulting synthetic dataset is then leveraged to train classification models, evaluating how sensor displacement data can infer contact conditions and object shape. Among the machine learning models tested, Random Forest and XGBoost classifiers exhibit the highest performance for shape prediction, with the best configuration achieving over 97% classification accuracy when utilizing a four-sensor setup. The findings demonstrate that integrating optimized FEM simulations with machine learning significantly improves predictive accuracy in sensor-based contact analysis. The proposed approach not only enhances the calibration of soft tactile sensors but also facilitates data-driven analysis of bioinspired adhesives. These results underscore the potential of combining physics-based modeling with data-driven approaches to refine sensor performance and improve decision-making in robotic systems. These advancements contribute to the broader application of gecko-inspired adhesives in robotic gripping and automated material handling, where precise adhesion and object classification are critical for performance and reliability.","url":"https://doi.org/10.24406/publica-4434","authors":["George, Kshema Maria",":unav"],"tags":["Gecko-inspired adhesives","finite element modeling","Bayesian optimization","contact area prediction","shape classification","soft tactile sensors","MatBeyoNDT"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.24406/publica-4434","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.48550/arxiv.2607.22964","name":"Pose-Aware Modeling to Mitigate Pose-Related Artifacts in Tactile Gloves","source":"datacite","abstract":"Tactile gloves digitize contact and force during hand-object interactions, enabling robotics applications in dexterous manipulation, teleoperation, and learning from demonstration.

However, such flexible sensors are sensitive not only to contact forces but also unavoidably to hand pose changes, resulting in pose-related artifacts (PRAs). PRAs are especially problematic in the low-force range, resulting in misdetections or late-onset detections of contact, which raises the minimum detectable force (MDF) of the glove. In this work, we characterize the PRAs in relation to pose and force. Building on these insights, we introduce a glove-agnostic algorithmic framework that leverages hand pose information, which is increasingly available, to mitigate PRAs without glove modifications.

To address this, we present Feature-Extracted Latent Tactile (FELT), a learning-based framework that synthesizes per-finger pressure tactile images from RGB observations, reducing the need for tactile-equipped data collection. FELT uses a large frozen visual encoder and a lightweight query decoder to predict tactile signals in a single feed-forward pass. To respect the physical topology of dual-finger tactile sensors, FELT decodes the left and right tactile sensor panels through separate branches, capturing the asymmetric contact patterns during interactions such as wiping, insertion, and in-hand rotation. At inference time, FELT only requires RGB data, allowing us to augment existing vision-only data with tactile observations, either as generated tactile images or as latent tactile features. Experiments on four contact-rich manipulation tasks demonstrate that both generated tactile images and latent tactile features improve policy success over vision-only baselines, with latent feature requiring no real tactile sensor during policy training or deployment.

This study presents a complete open-source MATLAB-based framework for the development and validation of compact deep learning models for affective touch recognition in soft interactive companions. As a primary contribution, a diverse FAIR-compliant dataset of 1326 labelled gesture sequences collected from 25 participants spanning children, teenagers, and adults is made publicly available, providing a reusable resource for future research in affective touch recognition. Through systematic architecture and hyperparameter exploration across 468 CNN models, the study identifies compact dilated one-dimensional convolutional neural networks (1D CNNs) as the most effective solution, with a 13.2k-parameter model achieving 75% test accuracy and 85% mean leave-one-subject-out cross-validation accuracy. Theoretical inference-time analysis shows that quantized deployment requires 3.2 MMAC per window, compatible with 20 Hz real-time operation on the target microcontroller. PC-based real-time simulation with the physical toy streaming sensor data demonstrates that the CNN resolves subtle social touches that the previous heuristic system failed to detect, whereas high-force negative interactions are captured more reliably by trivial threshold-based logic. The resulting hybrid inference pipeline - instantaneous heuristic filtering followed by CNN-based nuanced gesture classification - is proposed as the embedded deployment strategy.

The assessment consists of five physiological parameters: Appearance, Pulse, Grimace, Activity, and Respiration. Although widely used as an international standard, conventional APGAR assessment still relies on visual observation and manual evaluation by medical personnel, which may introduce subjectivity, inter-rater variability, and delays in clinical decision-making. Therefore, this study aims to design and develop an automated APGAR Score system integrated into an infant warmer to provide objective, rapid, and continuous assessment of newborn physiological conditions with minimal physical contact. The developed system integrates multiple sensor-based modules to evaluate all APGAR parameters. The Pulse parameter is measured using a Nellcor DS100A sensor based on the photoplethysmography (PPG) method to acquire heart rate (BPM) and oxygen saturation (SpO₂) data. The Activity parameter is detected using a flexible resistor sensor to identify changes in resistance caused by neonatal movement and muscle tone. The Appearance parameter is assessed using a TCS3200 color sensor to objectively detect newborn skin color, while the Respiration parameter is measured using a VX010 abdominal respiration sensor and an MPX2010DP pressure sensor with signal processing using a bandpass filter to reduce noise interference. The Grimace parameter is evaluated using a camera-based facial expression detection module supported by a Raspberry Pi 4B and MediaPipe FaceMesh framework, which analyzes 468 facial landmark points in real-time to identify reflex responses after tactile stimulation using a vibration motor. The hardware and software systems were designed using ESP32 and Raspberry Pi as processing units, sensor interface circuits, signal conditioning circuits, and LCD Nextion or portable touchscreen displays as real-time monitoring interfaces. The APGAR Score calculation system integrates all five parameters and presents the assessment results digitally on the infant warmer monitoring platform. System performance testing was conducted using an SpO₂ simulator and controlled experimental conditions to evaluate parameter stability, accuracy, and reliability. Data analysis included the calculation of mean values, standard deviation, and percentage error. The integration of an automated APGAR Score assessment system into an infant warmer provides a promising solution for improving neonatal evaluation by reducing assessment subjectivity, increasing measurement consistency, and supporting continuous monitoring of newborn physiological conditions. This prototype is expected to assist medical personnel in making faster and more accurate clinical decisions while maintaining the primary function of the infant warmer.

By using a checkerboard coating pattern, MuxGel interleaves tactile-sensitive regions with transparent windows for external vision.

A novel gyroid-infill bonding technique is introduced to form a durable elastomer-TPU interface without adhesives, yielding a lightweight and modular design compatible with large-scale tensegrity structures. A tactile-to-wrench neural network maps shear vector fields to six-dimensional force and torque measurements. Experimental results demonstrate accurate and stable wrench estimation with a mean squared error (MSE) of 0.1531 on static validation data and out-of-domain generalization under dynamic motion. Furthermore, full-system integration on a 12 kg tensegrity robot confirms the sensor's ability to reliably identify ground contacts. The system substantially improves the practicality of tactile feedback for tensegrity robots, offering a low-cost, reproducible, and physically interpretable pathway toward contact-aware proprioception and state estimation.

In contrast, state-of-the-art robotic systems, lack this ability due to inadequate tactile feedback. Likewise, tactile sensors developed to-date lack appropriate flexibility, multi-axial detection, sensitivity, dynamic range and frequency response. Therefore, this thesis aims to address these limitations by developing a tactile sensor using flexible electronics and nanomaterials. Cross-linked gold-thiol nanoparticle (NP) films were fabricated using inkjet printing, demonstrating patterning of features down to 30 µm. Bridge and cantilever-based normal force NP film sensors were fabricated on flexible and rigid substrates to achieve sensitivities of around 0.3 %/mN and 0.001 %/mN respectively. A novel multi-axial sensor was fabricated using soft-lithography with a polydimethylsiloxane (PDMS) elastomer mesa, a PDMS-polyimide (PI) substrate, and four NP film sensing elements. The mesa mimicked the epidermal ridges on the skin, localised the force onto the sensing elements and allowed high sensitivity detection of shear (0.037 %/mN, 0.036 %/mN) and normal forces (0.048 %/mN). To reduce the wiring and enable addressing of NP film sensors, two types of flexible low-voltage organic field-effect transistors (OFETs) were developed based on ion-gel and self-assembled monolayer (SAM) high capacitance dielectrics. SAM devices showed mobilities of ~0.9 cm^2 V^-1 s^-1, I_on/off ratios of 10^6 and cut-off frequencies at 1 kHz. Conversely, ion-gel devices showed mobilities of ~4 cm^2 V^-1 s^-1 and I_on/off ratios of 10^4, but a low cut-off frequency (~1 Hz) in its response due to the ions from the gel doping the semiconductor. A one-dimensional normal pressure sensing array was also developed, with an unstructured and structured PDMS layer under the deforming NP film. Sensors with structured PDMS exhibited sensitivities of up to 0.5 %/kPa, while sensors with unstructured PDMS had a dynamic range of 0-300 kPa and mechanical crosstalk as low as 4 % of its full scale output (FSO). The frequency response of both sensors showed cut-off frequencies between 100-150 Hz, comparable to a subset of human mechanoreceptors. An integrated NP film-OFET sensor was developed in an active taxel sensor configuration, enabling temperature compensation and amplification of sensitivity and signal output.","url":"https://doi.org/10.26190/unsworks/16700","authors":["Alvares, Darren"],"tags":["Tactile feedback","Tactile sensing","Organic transistors","Flexible sensors","Gold nanoparticles","Strain gauge","Printing"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2014","doi":"10.26190/unsworks/16700","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.26190/unsworks/15865","name":"Design of tactile sensors for robotic hand control and upper limb prostheses","source":"datacite","abstract":"In this thesis, a journey of development of newer tactile sensors and sensing techniques is presented. The characterisation of a novel capacitance-based, tactile sensor designed to measure shear forces is discussed. The sensor design is targeted for use in robotic and prosthetic hands, where haptic feedback or the ability to detect shear forces associated with slip are critical. Sensors with a full-scale displacement range of ±0.525 mm were produced and the differential capacitance, when measured at each fixed interval, was found experimentally to have a maximum standard deviation of 0.428 fF over a ±2 N range. A maximum standard deviation of 1.35 fF was measured across the full scale sensor range of ±4 N. Due to the capacitive nature of the sensor, it suffers from low dynamic frequency response and a higher standard deviation in output under larger deformation. The design and fabrication of a polyvinylidene fluoride (PVDF) based, mouse (or rodent) whisker mimicking, tactile sensor is also presented, which overcomes some of the limitations of the capacitance-based, shear sensing tactile sensor. Unlike previous designs reported in the literature, this sensor mimics the mouse whisker not only mechanically, but it also makes macro movements, just like a real mouse whisker in a natural environment. With the control system developed for this sensor, the whisker can vibrate between 5 to 236 Hz, similar to a real mouse whisker. The minimum standard deviation in sensor output, in terms of frequency is 0.649 Hz at 200 Hz, while minimum standard deviation in terms of voltage amplitude of sensor output is 0.0012 V at 200 Hz. The sensor has high bandwidth of 200Hz, but is limited to dynamic sensing only. To achieve both static and dynamic sensing, with high bandwidth, another design was conceived using a novel technique employing PVDF. Results show that within a test range of 0-12 N, applied static forces can be discriminated with a 95% level of confidence. Maximum standard deviation of 0.0074 V was observed at 1 N. The capacitance and both PVDF-based sensor designs, feature ease of mass production, low per-unit-cost, novel overload protection and a low wire count, while still preserving the ability to achieve reasonable spatial resolutions and array densities. Along the way, advantages and limitations of designs are discussed in detail and recommendations for future work are put forth.","url":"https://doi.org/10.26190/unsworks/15865","authors":["Tiwana, Mohsin Islam"],"tags":["haptic feedback","tactile","sensing"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2012","doi":"10.26190/unsworks/15865","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.26190/unsworks/15542","name":"Development of a tactile sensor for a robotic hand","source":"datacite","abstract":"A tactile sensor for robotic applications has been developed in this study, based on the functionality mechanoreceptors in the glabrous skin of the human hand.

Weapons are chassis-integrated rather than hand-held, keeping the silhouette compact and the armour continuous. The design prioritises internal volume for power and compute systems, with agility achieved through advanced materials and AI-coordinated actuation rather than light weight alone. Structure & Armour The cockpit is a steel roll-cage encased in carbon-polymer composite with a copper interlayer, housing laminated ballistic glazing in faceted panels with diamond/ceramic edge inserts. An inner ballistic-fibre and foam cocoon catches fragments and softens secondary impacts. The torso is a carbon-fibre monocoque reinforced with graphene rods. Leg and joint armour uses overlapping shingled panels of steel-face plus carbon-polymer core with copper grounding interlayers, following the same stack logic as the cockpit. Hydro-elastic ringlets — fluid-filled toroidal chambers with carbon-fibre/copper-mesh walls — sit at every major joint, providing impact absorption, rebound elasticity, and vibration damping. They operate in variable-fill mode: fully charged for combat, partially drained to 40% for leaps and sprints to reduce carried mass. Skeleton & Actuation Limb bones are hollow magnesium cores with titanium collars at joint ends and graphene-epoxy sleeves along mid-shafts, saving roughly 15–20% versus full titanium coating. Carbon-fibre leaf spring arches at ankle and knee replace titanium coil springs, storing comparable elastic energy at about 40% of the mass. Primary actuation uses SMA and EAP muscle bundles for sustained load-bearing and fine control, supported by torque amplifier nodes at knees and ankles and micro-polymer joint fill for compliance and friction reduction. Leap pistons sit in parallel with the SMA bundles at hip and knee: composite-wall hydraulic cylinders (80mm bore, 300–350 bar, carbon-fibre wound over steel liner) fed from 8-litre nitrogen-bladder accumulators in the upper thigh bays. Each piston delivers approximately 110 kN, giving the mech leaps of roughly 3–5 metres vertical. The accumulators recharge in 15–20 seconds from the 48V spine. Flowzone pre-drains the ringlets before a commanded leap and recharges them before landing using LiDAR height data. Performance: running at 15–20 m/s, top speed reached in under 3 seconds.

The majority of existing tactile sensors focus on determining the contact forces at the interface, or detecting a slip event at the contact interface. However, friction sensing or estimation of the coefficient of static friction (μ_s) has been largely ignored in the tactile sensing literature, despite the importance of friction for dexterous manipulation, particularly in unstructured environments. Furthermore, existing sensors have often not been integrated into any form of real-time grip force control systems. To fill such a gap in the research of tactile sensing for robotic gripping, this thesis proposes a new friction-sensing approach based on idealised physical principles of friction. Four generations of the friction sensor (the Spider/Spider2/Spider3 and the Walker) have been designed, fabricated, and evaluated, which can estimate μ_s between the sensors and a planar surface on initial contact. The development of the friction sensor follows an iterative process – that is, design, fabrication, evaluation and then redesign, etc. All the sensors are built upon design concepts like friction angle and sensor leg, such that μ_s can be estimated by determining whether the legs have slipped or not when pressed against a planar surface. In terms of evaluation of all four sensor prototypes, μ_s between the sensors and different test materials have been estimated and compared to reference measurements obtained using a traditional method for measuring friction. The experimental results indicate good consistency between the estimated coefficients and the reference values. More importantly, the most mature implementation of the friction sensor, the Spider3, has been integrated in a real-time robotic gripping system to demonstrate its feasibility in dynamic gripping scenarios. Gripping tasks have been performed with and without the Spider3. Manipulation performance has been quantised with consideration of grip safety and electrical power consumption which are reflected by drop rate and actual grip force, respectively. As a result, using the Spider3 to estimate the friction always incurs a lower cost, indicating its superiority in terms of both grip safety and power consumption.","url":"https://doi.org/10.26190/unsworks/20750","authors":["Chen, Wei"],"tags":["Coefficient of static friction","Friction sensing","Robotic manipulation"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2018","doi":"10.26190/unsworks/20750","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.48550/arxiv.2606.22332","name":"Tactile Genesis: Exploring Tactile Sensors at Scale for Learning Dexterous Tasks","source":"datacite","abstract":"Tactile sensing is critical for contact-rich dexterous manipulation, yet it remains unclear which tactile abstractions a policy needs and when richer tactile fields justify their hardware cost. This is hard to study empirically: each sensor effectively defines a new robot, and no lab can replicate the same learning experiment across all of them. We present Tactile Genesis, a GPU-parallel tactile sensor simulation platform that exposes binary contact, contact depth, per-taxel kinematic force/torque, elastomer marker displacement, geometry-aware proximity, contact audio, and a voxelized temperature field (the first of its kind in robot learning physics simulation platforms) under a common interface, with configurable placement, resolution, and a realistic noise model (drift, hysteresis, dead taxels, crosstalk). It scales past 20,000 parallel environments and 1,000 taxels on a single GPU, improving throughput by 3 to 20 times over previous tactile simulators. We train teacher-student policies on three dexterous tasks, ablating sensor type, placement, resolution, and noise, and verify transfer to the real XHand1. Proprioception alone is insufficient on every task. Sensor placement dominates sensor type: fingertip-only coverage trails whole-hand coverage by a wide margin, while adding the palm and proximal phalanges closes most of the gap to the privileged teacher. Resolution matters far less than coverage: placing 200 taxels across the whole hand suffices across tasks. We find that force/torque per taxel is consistently the most useful sensor type. These results give concrete guidance for both future tactile hardware design for improving robot hands and policy-side observation choice in dexterous manipulation. https://neuroagents-lab.github.io/tactile-genesis/","url":"https://doi.org/10.48550/arxiv.2606.22332","authors":["Chung, Trinity","Yamazaki, Kashu","Patel, Dhruv","Duburcq, Alexis","Qiao, Yiling","Fragkiadaki, Katerina","Nayebi, Aran"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.22332","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.26190/unsworks/25134","name":"Development of Advanced Soft Robotic System for Endoscopic Surgery and In Situ 3D Bioprinting with Haptic Display","source":"datacite","abstract":"Gastrointestinal (GI) cancer is a leading cause of cancer death worldwide. Early removal of adenomatous polyps offers a fantastic outcome, with a 5-year survival rate exceeding 90%. Endoscopic submucosal dissection (ESD) is a minimally invasive approach to removing GI polyps, known for its high success in achieving en bloc resection. Despite the benefits of ESD with its low complication rates and short hospital stays, existing technologies have several limitations such as the need for multiple tools during the procedure and high force loss caused by rigid cables with nonlinear friction and backlash hysteresis. The nonlinearity can lead to imprecise control of surgical tools while the force loss hinders the tool's ability to access lesions located in the transverse and ascending colons. In addition, no endoscopic robots are equipped with soft 3D bioprinting capabilities to deliver in situ wound sealants for defect tissues. Finally, existing systems lack real-time force sensing and haptic display compared to open surgery, making optimal surgical procedures challenging. This thesis will develop a multifunctional and flexible soft robotic endoscopic system that can perform ESD and in situ 3D bioprinting. The new system features a high degree of freedom soft surgical head integrated into a long and flexible snake-like robotic arm that can access confined and hard-to-reach areas via small skin incisions or natural orifices. The device has a user-friendly design with a master-slave architecture and is operated by kinematic inversion models and a learning-based controller for precise tip motions. In addition, the system is equipped with a new 3D force sensor and an advanced haptic display that can efficiently reproduce the sense of touch for a better endoscopic procedure. The whole system is driven by a new soft microtubule artificial muscle (SMAM) that can be programmed to elongate and contract under hydraulic pressure. Mathematical models and advanced control algorithms are proposed to reduce the system's nonlinearity impact. The system's capability for endoscopic surgery with the haptic display is shown through two user studies and fresh porcine tissue. 3D printing abilities with various patterns on several surfaces and a colon phantom are further tested with different composite hydrogels and biomaterials. The new system is expected to fill a gap in the field of advanced endoscopic surgical robots while also assisting in the future growth of in situ bioprinting.","url":"https://doi.org/10.26190/unsworks/25134","authors":["Thai, Mai Thanh"],"tags":["Surgical robotics","Endoscopic Submucosal Dissection","In-situ 3D Bioprinting","Soft Artificial Muscle","3D Force Sensor","Haptic Display","Skin Stretch Device","Tactile Feedback"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.26190/unsworks/25134","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.26190/unsworks/31152","name":"An Integrated, 3D Conformal Electronic Device for Bioimpedance Sensing in Surgical Endoscopy","source":"datacite","abstract":"Minimally invasive surgeries (MIS), in conjunction with endoscopy, offer significant advantages over traditional methods for treating colorectal cancer, including minimal incisions, faster recovery, and improved overall efficiency. Over the years, several miniaturised sensors have been developed to enhance procedures with soft medical robots by providing proprioceptive, exteroceptive, and diagnostic insights essential for a successful operation. Among them, tactile sensors are by far the most common sensor type in the diagnosis of tissue malignancy based on the difference in mechanical properties between healthy and cancerous tissues. However, such difference is generally nuanced until a late-stage malignancy. In contrast, sensing through tissue electrical properties, such as bioelectrical impedance, offers an alternative solution for distinguishing abnormalities due to the pronounced differences between various tissue stages. However, the integration of impedance sensors onto soft medical robots has not been fully explored. Onsite impedance sensing necessitates a low interfacial impedance at the sensor-tissue interface, whilst maintaining intimate contact with bio-tissue. This thesis proposes a 3D curvilinear electronic device based on mesoporous gold (mAu) sensors integrated onto an endoscope, offering significantly lower interfacial impedance, high sensitivity compared to conventional flat gold, and conformal contact with the bio-tissue during onsite sensing procedures. Employing a combination of top-down lithography, bottom-up electrochemical deposition, and a liquid-based transfer technique, the thesis project successfully demonstrated the integration of mesoporous electrodes onto the curvilinear surface of an endoscopic-based soft robotic end-effector. The results showed that mAu electrodes exhibit interfacial impedance an order of magnitude lower than flat Au in biomimetic fluids and approximately 2.5 times higher bioimpedance sensitivity. These findings highlight their promising potential for bioimpedance-based sensing applications.","url":"https://doi.org/10.26190/unsworks/31152","authors":["Qiu, Peter"],"tags":["3D mesoporous electrodes","soft surgical robotics","endoscopy","cancer detection","4003 Biomedical engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.26190/unsworks/31152","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.48550/arxiv.2607.07897","name":"Monocular Vision Based Control Framework for Grasping","source":"datacite","abstract":"Grasping in unstructured environments requires handling objects with widely different mechanical properties, from soft and deformable items to rigid everyday objects. Most existing approaches address these categories separately and often rely on tactile sensing, object-specific models, or specialized grippers. In this paper, we present a unified monocular vision-based grasping framework that targets both soft and rigid objects within a single control pipeline, using only RGB input and a position-controlled gripper. The proposed system combines open-vocabulary object detection, image segmentation, boundary-aware point assignment, real-time point tracking, and monocular depth estimation to recover object motion and geometry from visual observations. A key component of the framework is a language-based stiffness estimation model that infers an object's expected compliance from its semantic description and provides an object-level prior for selecting the grasping strategy before contact. For deformable objects, grasp adaptation is governed by a Procrustes-based dissimilarity measure computed from tracked keypoints, which acts as a visual proxy for deformation. For rigid objects, the gripper width is regulated through the scaling of tracked point distances. We validate the proposed method in real-world pick-and-place experiments on a Franka Emika Research 3 arm using objects with substantially different mechanical properties, including lettuce, fresh mozzarella cheese, croissants, paper towels, and hard plastic bottles. Results demonstrate that the framework achieves stable grasping across both soft and rigid objects using visual feedback alone, highlighting a practical, sensor-efficient, and generalizable approach for food handling and household manipulation.","url":"https://doi.org/10.48550/arxiv.2607.07897","authors":["Jadav, Shail","Lee, Dongheui"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2607.07897","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.5281/zenodo.21266965","name":"PREreview of \"Inter-brain Synchronization in the Alpha Band during Minimal Tactile Interaction\"","source":"datacite","abstract":"This Zenodo record is a permanently preserved version of a PREreview.

Inspired by insect antennae—compliant, distributed sensors that efficiently process tactile information through physical intelligence—we investigated whether mechanical design and active touch sensing strategies could enhance robotic tactile feature perception. We hypothesized that insect-inspired antenna dynamics, specifically flexural stiffness gradients and active touch speed, could simplify tactile classification. Using a sim-to-real framework that bridges bioinspired computational models with a multi-link soft robot antenna, we introduce the notion of tactile fields—spatiotemporal representations of tactile stimuli shaped by contact location, feature type, and active touch speed. Our analyses show that cockroach-inspired antenna mechanics jointly with active touch speeds improve feature classification accuracy compared to conventional sensors with uniform flexural stiffness gradient by increasing tactile data sparsity and dispersion. An exploration of stiffness and damping of antenna mechanics revealed design trade-offs that influence tactile discrimination and structural stability. Through sim-to-real transfer, stiffness gradients and structured active touch motions were demonstrated on a miniature distributed soft robotic antenna, validating their effectiveness in real-world robotic systems. Taken together, this work presents a biologically grounded framework for tactile sensor design that reduces computational load and enhances adaptability.","url":"https://doi.org/10.26207/tmsg-ad78","authors":["Jean-Michel Mongeau","Lingsheng Meng"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.26207/tmsg-ad78","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.5281/zenodo.21153099","name":"KO'RISHDA NUQSON BO'LGAN BOLALARNING FIZIOLOGIYASI VA PSIXOFIZIOLOGIK O'ZIGA XOS XUSUSIYATLARI","source":"datacite","abstract":"Mazkur tadqiqot ko'rishda nuqson bo'lgan bolalarning fiziologik va psixofiziologik xususiyatlarini o'rganishga bag'ishlangan.

As a result, it is impractical to pretrain policies with every sensor they may encounter. We study multisensory continual learning: adapting a pretrained robot policy to new tasks with newly introduced modalities while preserving performance under the original sensor suite. We propose MultiSensory World Model (MuSe), which incorporates limited multisensory data into pretrained vision-only policies through multi-stage fusion, multisensory future prediction, and experience replay over pretraining data. We instantiate MuSe by augmenting a pretrained vision-only policy with force-torque sensing and evaluate it on real-world manipulation tasks. Our experiments show that MuSe performs strongly on contact-rich finetuning tasks while preserving, and in some cases improving, performance on the original pretraining tasks.

The resulting dataset is fifty times larger than previous datasets and incorporates ground truth geometry essential for supervised learning. Deep learning networks are created to reconstruct the geometry of samples the sensor touches, as both depth maps and surface normal maps. The reconstructed geometry from multiple captures from the sensor are then stitched together to create broader views of larger samples. The success of these methods is evaluated on a set of physical samples that mimic colorectal cancer polyps.","url":"https://doi.org/10.26153/tsw/64165","authors":["Bonyun, Jeffrey V.","0009-0003-9851-7648"],"tags":["Tactile sensor","Vision-based tactile sensor","VB-TS","Gelsight","Colon cancer","HySenSe","Geometry reconstruction","Stitching"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.26153/tsw/64165","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.5281/zenodo.21195584","name":"Mind City","source":"datacite","abstract":"so its 24 claims which is still under 25 its social media at its core MINDSPACE — Complete Feature List Core architecture & hardware Central Hub (octa-core ARM Linux) with powered USB tree Cities Hub — 6-slot sovereign WiFi city selector (city0–city5) Presence Headset (light-only canonical build; optional micro-OLED tier) Tracer/Volco handheld messenger & scene controller TIM temple module — vibration, IMU, EEG/fNIRS pickup Arm/leg kinetic cuffs (torque, PPG, EDA) Clasp hand units — pressure, warmth, skin-stretch, pulse Earbuds, olfactory micro-cartridge module, tongue-tip gustatory interface, Peltier thermal §19 Cryogenic compute tiers (wearable mild-cryo → docked 77K → fixed 4K sovereign node) §20 Optional Meta Quest visual tier (stylised MindCity, tier-parity law, honest biosensing trade) The sensory engine Suggestion-completion law (§0) with formal fidelity model E = C·Σ aᵢPᵢ Upgraded tactile stack: vibrotactile, pressure, thermal, skin-stretch Intent pipeline — motor-imagery + intent-vector JSON schema Cross-modal session clock (25–50ms binding window) Per-user calibration profiles Safety & consent (the spine) Default-off everything; global + per-contact cue permissions Continuous-consent state machine with live-hold invariant 8-gate safety interlock cascade, fail-closed; STOP always wins Waking-only check, load/trauma throttle, Valor's Virtue ethical filter Hardware kill line (§18); pressure/thermal/current hard caps Mnemosyne minimal logging; intimate content never recorded §2.1 Founder's Writ — manual, rare, logged sanction (restriction or expulsion) Places & experiences MindCity districts (Beach, Downtown, Library…) Travel scene-packs (train, boat, plane) Date rooms: dinner, beach, spa, Coffee Shop, Bar/Lounge Fields (touchable grass), Poetry Corner Date activities: slow dance, listen-together, walks, couple's ride, skydive, fishing, minigames, stargazing Wind-down & goodnight sequence Bike riding + Bike Shop; kinetic thought-driven motion Emotion & presence Echoes — moment capture, self-replay, consented community sharing with affect screening Emotion amp (capped, positive-only, throttle-overridden) Physicants heart-rate biofeedback (nudge, never control) Clasp hand-holding across distance (≤50ms budget) Flavour layer — aroma + primary-taste accents Fully-mental intimacy (SMI, adults-only, strictest consent tier) Live emotion tag-lines, standing vibe tags Social — the Commons No-faces bios (rich multi-field, intent tags, Examine abstract avatars) Friendship as first-class intent with escalation walls & double-gated intent alignment Group chat rooms, interest rooms, host controls Word games, co-op puzzles, party games, presence games The Board — ads (no affect targeting, ever), sourced news, blogs; anti-doomscroll by construction Content & world boundary §21 The Membrane — self-contained ingress: creative content wide open, news by published allowlist, public registry with logged changes, user quiet mode (\"no world today\") §23 The Press — governed egress: thermal poem slips, postcard art prints; printable-flag consent; ink out, never data Art — the Atelier (§22) In-platform painting (tablet, air-paint, hand-tracking, motor-imagery) with haptic canvas Emotional trace binding — per-stroke affect recording; three-switch sharing (image/mood/trace) Art economy: originals, prints, escrowed commissions, patronage; coin cash-out for artists; no affect data in commerce, ever Community galleries: bio shelves, open themed galleries, curated exhibitions with opening nights Economy Wellness-derived coin economy; cosmetics, routes, placements, tips One-directional cash bridge (anti-speculation); published flat platform fee Roughly sixty features, one law underneath all of them: imply, and the mind completes — with consent holding every door. best explanation It is — and I don't think that was the plan, which is what makes it true.

Replicating the versatility of skin artificially is a significant challenge, not only in terms of signal processing but also in mechanics. Stretchable electronics are an approach designed to cover human and artificial limbs and provide wearable sensing capabilities: motion sensors distributed on the hand of neurologically impaired patients could help therapists quantify their abilities; prostheses equipped with multiple tactile sensors could enable amputees to naturally adjust their grasp force. Skin-like electronic systems have specific requirements: they must mechanically adapt to the deformations imposed by the body they equip with minimal impediment to its natural movements, while also providing sufficient electrical performance for sensor transduction and passing electrical signals and power. A metallization ensuring stable conductivity under large strains is a prerequisite to designing and assembling wearable circuits that are integrated with several types of sensors. In this work, two innovative metallization processes have been developed to enable scalable integration of multiple sensing modalities in stretchable circuits. First, stretchable micro-cracked gold (Au) thin films were interfaced with gallium indium eutectic (EGaIn) liquid metal wires. The Au films, thermally evaporated on silicone elastomer substrates, combined high sheet resistance (9 to 30 Ohm/sq) and high sensitivity to strain up to 50%. The EGaIn wires drawn using a micro-plotting setup had a low gauge factor (2) and a low sheet resistance (5 mOhm/sq). Second, a novel physical vapor deposition method to deposit of thin gallium-based biphasic (solid-liquid) films over large areas was achieved. The obtained conductors combined a low sheet resistance (0.5 Ohm/sq), a low gauge factor (~1 up to 80% strain), and a failure strain of more than 400%. They could be patterned down to 10 µm critical dimensions. Skin-like sensors for the hand were assembled using the two processes and their capabilities were demonstrated. Thin (0.5 mm) silicone strips integrating EGaIN wires and micro-cracked Au strain gauges were mounted on gloves to encode the position of a biomimetic robotic finger and a human finger. In combination with soft pressure sensors, they enabled precise grasp analysis over a limited range of motion. Then, biphasic films were micro-patterned on silicone to assemble 50 µm thin epidermal strain gauges. The strain gauges were attached on a user's finger and accurately encoded fine grasping tasks covering most of the human hand range of motion. The biphasic films were also used to power wireless MEMS pressure sensors integrated in a rubber scaffold. The device was mounted on a prosthetic hand to encode normal forces in the 0 N to 20 N range with excellent linearity. The epidermal strain sensors are currently being used to quantify the tremors of patients with Parkinson's disease. In the future, the unique properties of the biphasic films could enable advanced artificial skins integrating a high density of soft transducers and traditional high-performance circuits.","url":"https://doi.org/10.5075/epfl-thesis-7848","authors":["Michaud, Hadrien Olivier"],"tags":["electronic skin","stretchable conductors","thin films","liquid metals","gallium","strain gauges","motion sensing","prosthetics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2017","doi":"10.5075/epfl-thesis-7848","addedAt":"2026-08-31T06:34:47.882Z","updatedAt":"2026-08-31T06:34:47.882Z"},{"id":"doi:10.5281/zenodo.21194468","name":"Mind City","source":"datacite","abstract":"These two documents together form a complete picture of MindSpace — your consent-gated multisensory presence platform — split into the what it's made of and the what it does.

However, static designs always come with trade-offs: considering stiffness, soft compliant sensors ensure a better contact, but at the price of mechanically filtering and altering the detected signal. Conversely, online adaptable filters can tune their characteristics, becoming softer or stiffer when needed. We propose a magneto-active elastomer filter which, when placed on top of the tactile unit, allows the sensor to change its stiffness on demand. We showcase the advantages provided by online stiffening adaptation in terms of information gained and data structure.

The progress and development of these devices has been supported by advancements in technologies such as soft actuators, flexible sensors and wireless acquisition devices. Some of the features desired for wearables are ergonomic design, low-cost, lightweight, and high accuracy. 3D printing allows for design of complex geometries, customization, and implementation of various materials at a low-cost, including in this work ultraflexible and flexible conductive materials. This study focuses on a glove prototype with 3D printed flexible sensors attached to the finger sections of the glove. The sensors were produced with Fused deposition modeling (FDM) printing using a Lulzbot Taz 6 3D printer. The prototype takes advantage of resistance-based sensors made of a custom conductive, flexible 3D printed filament and the insulating effects of standard commercial thermoplastic polyurethane. The sensors were printed and placed on the index finger of the glove for reading finger movements as the finger bends. The sensors were connected to a Wheatstone bridge circuit to monitor the changing resistance. As the sensors on the glove bend, the resistance and in turn voltage values change proportionally to the deformation of the actuator. The rotation angle and radius of the actuator were measured using deformation tracking software. The data from these tests was collected and analyzed. There are multiple applications of this technology. The first application of this technology is to help with rehabilitation efforts. These flexible sensors can be applied to multiple parts of the body and give real time data on a patient’s movement. This can be beneficial to patients who have lost their mobility. The data from these sensors can be used by medical professionals to assess the progress the patient is making in their mobility and to adjust their treatments. Another application of this research is in the virtual reality space to be used as virtual reality gloves. The sensor data can be used by virtual reality developers to progress the game to increase user precision as well as realism.","url":"https://doi.org/10.1115/smasis2024-140240","authors":["David Moreno-Rueda","Diana Narvaez","Evelyn McCarthy","Liam McCormack","Brittany Newell"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-28T11:18:29Z","doi":"10.1115/smasis2024-140240","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.1109/apscon60364.2024.10465895","name":"Thread based Resistive Sensor for Tactile and Slippage Detection in Smart Bionics","source":"crossref","abstract":"","url":"https://doi.org/10.1109/apscon60364.2024.10465895","authors":["Benish Jan","Mudra Chavda","Sameer Sonuksale","Shahid Malik"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-03-19T14:11:33Z","doi":"10.1109/apscon60364.2024.10465895","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.1109/icit58233.2024.10540981","name":"An Innovative Tactile Sensor Roller for Composites Inspection","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icit58233.2024.10540981","authors":["Zhenyu Lu","Xiaolong Li","Tunwu Li","Xiaodong Xu","Chenguang Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-05T17:38:41Z","doi":"10.1109/icit58233.2024.10540981","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.1016/j.ifacol.2024.07.368","name":"A Method of Tactile Resistive Sensor Array Calibration","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.ifacol.2024.07.368","authors":["Michal Husák","Ondrej Mihálik","Petr Dvorský","Zdeněk Bradáč"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-14T07:29:32Z","doi":"10.1016/j.ifacol.2024.07.368","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.1109/icra57147.2024.10610615","name":"MagicTac: A Novel High-Resolution 3D Multi-layer Grid-Based Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra57147.2024.10610615","authors":["Wen Fan","Haoran Li","Dandan Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-08T17:51:05Z","doi":"10.1109/icra57147.2024.10610615","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.1504/ijwmc.2024.10065183","name":"A tactile sensor based on photoelasticity","source":"crossref","abstract":"","url":"https://doi.org/10.1504/ijwmc.2024.10065183","authors":["Bo Tao","Zhili Huang","Wenqiong Zhu","Gongfa Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-07-05T14:57:02Z","doi":"10.1504/ijwmc.2024.10065183","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.1016/j.apmt.2024.102521","name":"Artificial tactile perceptual system based on capacitive tactile sensor and oxide neuromorphic transistor","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.apmt.2024.102521","authors":["You Jie Huang","Jia Kang Di","Wei Sheng Wang","Xin Huang","Si Yuan Zhou","Bei Chen Gong","Zi Qi Zhao","Li Qiang Zhu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-11-17T01:43:43Z","doi":"10.1016/j.apmt.2024.102521","addedAt":"2026-08-31T06:34:48.948Z","updatedAt":"2026-08-31T06:34:48.948Z"},{"id":"doi:10.2139/ssrn.4794721","name":"Simulation and Theory of New Dielectric-Piezoelectric Tactile Sensor Based Electromechanical Impedance for Static Load","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.4794721","authors":["Amir  hosein Ramezani","Hamid  Reza Mirdamadi","Mahdi Salmani-Tehrani"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-15T13:49:23Z","doi":"10.2139/ssrn.4794721","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.2139/ssrn.4728276","name":"A Self-Powered Flexible Tactile Sensor Utilizing Chemical Battery Reactions to Detect Static and Dynamic Stimuli","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.4728276","authors":["Sen Li","Yu Cheng","Ka Deng","Hongyan Sun"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-15T22:19:07Z","doi":"10.2139/ssrn.4728276","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/robosoft60065.2024.10521971","name":"Softness Prediction with a Soft Biomimetic Optical Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robosoft60065.2024.10521971","authors":["Saekwang Nam","Toby Jack","Loong Yi Lee","Nathan F.

However, most tactile pressure sensors in the literature output an electrical or optical signal increasing the complexity of soft devices as the electrical or optical signals are transduced from the sensors to fluidic logic, and electrical power is needed just for the purposes of sensors and transducers. Including electrical and optical materials into a soft device also complicates the fabrication of the device. To address these drawbacks, we propose a soft pneumatic tactile pressure sensor matrix consisting of four sensors and operating on fluidic principles. Each sensor contains a meandering microchannel fabricated only from the same elastomer typically used in soft devices. When compressed, the pressure drop of the channel changes, which is measured as a sensor output signal. Our sensors can detect forces ranging from under 0.1 N to 4 N, with a maximum sensitivity of 50.5 N −1 . They have a hysteresis of 3.9% and the sensor signal drifts 16.4% in 12 hours under static compression. By using multiple sensors in a matrix, we can detect the point of contact and the magnitude of the applied force. Furthermore, we demonstrate that by attaching a protruding post to the matrix, we can infer forces acting on the post in three axes. This work paves the way toward electronics-free, entirely fluidic soft devices and soft robots that can detect not only the magnitudes of the contact forces but also their locations.","url":"https://doi.org/10.1089/rorep.2024.0034","authors":["Vilma Lampinen","Anastasia Koivikko","Mika Pihlajamäki","Vipul Sharma","Veikko Sariola"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-27T04:53:05Z","doi":"10.1089/rorep.2024.0034","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:48.949Z"},{"id":"doi:10.1109/icra57147.2024.10610733","name":"Thermoformed electronic skins for conformal tactile sensor arrays","source":"crossref","abstract":"","url":"https://doi.org/10.1109/icra57147.2024.10610733","authors":["Peng Lu","Jiaming Liang","Bidan Huang","Sicheng Yang","Wang Wei Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-08T17:51:05Z","doi":"10.1109/icra57147.2024.10610733","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:48.949Z"},{"id":"doi:10.1109/iros58592.2024.10801624","name":"Fingertip Tactile Sensor for Detecting Rope Slip","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros58592.2024.10801624","authors":["Takayuki Koga","Junya Sato","Takuya Daigo","Kohei Kimura","Shunsuke Kudoh"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-25T19:17:39Z","doi":"10.1109/iros58592.2024.10801624","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:48.949Z"},{"id":"doi:10.1109/biorob60516.2024.10719951","name":"Braille-Tip: Structured Small-Footprint Tactile Sensor for High Acuity Dynamic Tactile Tasks","source":"crossref","abstract":"","url":"https://doi.org/10.1109/biorob60516.2024.10719951","authors":["George P.

However, the use of these gripping systems still requires precise manual adjustment of the gripping parameters. To address this limitation, a coil‐based sensor is designed to enable automatic detection of the attachment process. The sensor consists of three sensing, one transmitting coil, a conductive film, and a compliant layer. The components are optimized to achieve reproducible, precise measurements, and minimize hysteresis effects of the components. A mathematical concept to calculate the geometrical relations between the gripping object and the gripper is established based on triangulation. The functionality of the sensor system is demonstrated in contact experiments with a glass substrate under different tilt angles, and an accuracy of 0.042 degree is achieved. The sensor system not only allows precise detection of the misalignment angle but also fast estimation of the qualitative direction of misalignment with minimal compression.

However, many previous studies have been limited by low sensitivity and insufficient spatial resolution. In this study, we developed high-resolution tactile sensor arrays integrated with vertically aligned carbon nanotube (VACNT) bundles, achieving a spatial resolution with a 1 mm pitch. The patterned VACNT bundles are synthesized on a micropyramidal silicon mold and subsequently transferred onto a polymer substrate to form a pressure-sensitive layer. The VACNTs were synthesized via a chemical vapor deposition process, resulting in excellent uniformity with only 4.23% variation among the pressure-sensing cells. When pressure was applied, the contact area increased both between the exposed VACNT strands and the electrodes, and among the VACNTs embedded within the polydimethylsiloxane matrix. This dual-contact mechanism led to a high sensitivity of 40.6 kPa - 1 across a pressure range of 0-100 kPa. Leveraging these advantageous properties, we successfully demonstrated a pressure distribution measurement system capable of detecting both the magnitude and spatial distribution of subtle pressure.","url":"https://doi.org/10.1021/acsnano.5c20779","authors":["Sim S","Han H","Bae K","Kang Y","Jo E","Kim J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1021/acsnano.5c20779","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"doi:10.1021/acsami.5c19893","name":"Wearable Soft Ionic Tactile Controller for Virtual Reality: Decoupling Normal and Shear Forces without Motion Artifacts.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsami.5c19893","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1021/acsami.5c19893","addedAt":"2026-08-31T06:34:48.949Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1002/smtd.202501650","name":"Bioinspired Data Driven Interface Regulated Wearable 3D Motion Communicator for Human Finger Electronics.","source":"pubmed","abstract":"Data-driven flexible motion sensors have drawn more attention recently.

In this review, recent advances in the use of oxide TFTs for low-power electronics are systematically summarized. First, the inherent advantages of oxide semiconductor materials over other commonly used materials (e.g., amorphous hydrogenated silicon, low temperature polycrystalline silicon, organic semiconductors, etc.) for realizing low power consumption are demonstrated. Then, strategies to reduce power consumption are further discussed, including interface engineering, such as the novel source-gated transistors, and structural engineering, such as dual-gate and underlap designs. Finally, a comprehensive review of oxide TFTs for various low-power electronics applications, including logic circuits, active-matrix arrays, flexible electronics, monolithic 3D integration, and neuromorphic computing, is presented, demonstrating their great potential in future low-power and flexible electronic systems.","url":"https://doi.org/10.1002/advs.202522487","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/advs.202522487","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1007/s40820-025-02028-0","name":"Synaptic Plasticity Engineering for Neural Precision, Temporal Learning, and Scalable Neuromorphic Systems.","source":"europepmc","abstract":"Manipulating the expression of synaptic plasticity in neuromorphic devices provides essential foundations for developing intelligent, adaptive hardware systems.

This review highlights how diversified plasticity behaviors, including multilevel long-term potentiation and depression for spatial models, tunable short-term memory for temporal models, as well as wavelength-selective response, excitatory and inhibitory synergy, and adaptive threshold modulation, collectively support key tasks such as stable learning, temporal processing, and context-aware adaptation. Beyond behavioral innovations, strategies such as multifunctional single-device integration, multimodal fusion, and heterogeneous system assembly enable compact, energy-efficient, and versatile neuromorphic architectures. Recent developments at the array level further demonstrate high-performance scalability and system-level applicability. Despite notable progress, current modulation strategies remain constrained in flexibility, diversity, and large-scale coordination.

In this EEG study, we examined sensor (scalp)-level theta and alpha-band oscillations, as well as fronto-parietal network connectivity, during a tactile spatial discrimination task. Blindfolded participants judged the lateral offset of the central dot in a three-dot array delivered to the right index finger while an EEG was recorded. Time-frequency analyses revealed that both theta and alpha power were greater for correct than incorrect decision trials during pre-stimulus and post-stimulus intervals, suggesting enhanced preparatory and mnemonic engagement during accurate decisions. Directional connectivity assessed using block (multivariate) Granger causality demonstrated significantly stronger frontal-to-parietal influence in the theta band during both pre- and post-stimulus periods for correct decisions, supporting the role of long-range theta communication for top-down control in guiding tactile judgment. These findings highlight theta-band fronto-parietal communication as a key mechanism supporting successful tactile decision-making.","url":"https://doi.org/10.3390/life16030390","authors":["Mukherjee P","Apraku S","Dhamala M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/life16030390","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1021/acs.chemrev.4c00966","name":"Skin-Integrated Soft Wearable XR Interfaces for Seamless and Realistic User Experience.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acs.chemrev.4c00966","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1021/acs.chemrev.4c00966","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1038/s41467-025-68139-9","name":"Perpendicular neuromorphic channels facilitate lateral inhibition for tactile location.","source":"europepmc","abstract":"","url":"https://doi.org/10.1038/s41467-025-68139-9","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41467-025-68139-9","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/smtd.202502195","name":"Wearable Sensors Fabricated by 3D-Printed Composite Hydrogel with 2D Fillers.","source":"europepmc","abstract":"","url":"https://doi.org/10.1002/smtd.202502195","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/smtd.202502195","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1002/adma.202516218","name":"Self-Elevated 3D Helical Oscillator with Addressable Eigenfrequency for Wearable Interface.","source":"pubmed","abstract":"","url":"https://doi.org/10.1002/adma.202516218","authors":["Ding S","Dai Z","Zhao D","Guan X","Quan Y","Wang M","Zhou Y","Zhong J","Zhou B"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/adma.202516218","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1021/acsami.5c23259","name":"Multicolor-Emissive Carbon Quantum Dots Sensitized into Nanolaminated Piezoelectric Biofilms for Multifunctional Sensing.","source":"europepmc","abstract":"","url":"https://doi.org/10.1021/acsami.5c23259","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1021/acsami.5c23259","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1002/smtd.202501966","name":"Organic Transistor-Based Neuromorphic Electronics and Their Recent Applications.","source":"europepmc","abstract":"Neuromorphic technologies offer a promising pathway to address the escalating energy demands of artificial intelligence.

Robotic prostheses offer a promising solution by mimicking many of the functions of a natural arm, leading to an increasing need for advanced prosthetic designs. However, developing an effective robotic hand prosthesis is far from straightforward. It involves several critical steps, including creating accurate models, choosing materials that balance biocompatibility with durability, integrating electronic and sensory components, and perfecting control systems before final production. A key factor in ensuring smooth, natural movements lies in the method of control. One popular approach is to use electromyography (EMG), which relies on electrical signals from the user's remaining muscle activity to direct the prosthesis. By decoding these signals, we can predict the intended hand and arm motions and translate them into real-time actions. Recent strides in machine learning have made EMG-based control more adaptable, offering users a more intuitive experience. Alongside this, researchers are exploring tactile sensors for enhanced feedback, materials resilient in harsh conditions, and mechanical designs that better replicate the intricacies of a biological limb.

Space exploration involves several systems including satellites, space suits, communication systems, and robotics, which have to function under harsh space conditions such as extreme temperatures (- 270 to 1650 °C), microgravity (10⁻⁶ g), unhealthy humidity ( 60% RH), high atmospheric pressure (~ 1450 psi), and radiation (4000-5000 mSv). Conventional energy-harvesting technologies (solar cells, fuel cells, and nuclear energy), that are normally used to power these space systems have certain limitations (e.g., sunlight dependence, weight, degradation, big size, high cost, low capacity, radioactivity, complexity, and low efficiency). The constraints in conventional energy resources have made it imperative to look for non-conventional yet efficient alternatives. A great potential for enhancing efficiency, sustainability, and mission duration in space exploration can be offered by integrating triboelectric nanogenerators (TENGs) with existing energy sources. Recently, the potential of TENG including energy harvesting (from vibrations/movements in satellites and spacecraft), self-powered sensing, and microgravity, for multiple applications in different space missions has been discussed. This review comprehensively covers the use of TENGs for various space applications, such as planetary exploration missions (Mars environment monitoring), manned space equipment, In-orbit robotic operations /collision monitoring, spacecraft's design and structural health monitoring, Aeronautical systems, and conventional energy harvesting (solar and nuclear). This review also discusses the use of self-powered TENG sensors for deep space object perception.

However, conventional tactile sensors face challenges in accurately measuring pressure because vertical deformation is induced by Poisson's ratio in situations where lateral strain is applied. This study shows a strain-insensitive flexible tactile sensor array without the crosstalk effect using a highly stretchable mesh. This sensor is fabricated by assembling a sensing layer in which sensing cells form in each hole of an elastomer mesh and liquid-metal-based stretchable electrode layers. Stretching deforms the soft mesh layer with little effect on the rigid sensing cell array, which results in the sensor being insensitive to uniaxial strain. In addition, each sensing cell is formed in a dome shape, which resulted in a sensor exhibiting high sensitivity (7.80 kPa -1 ) over a wide sensing range (&lt;160 kPa). The proposed design also allows each sensing cell to be electrically separated, enabling the pressure measurements without cell-to-cell crosstalk. Based on these characteristics, strain-insensitive pressure monitoring is demonstrated to prevent carpal/cubital tunnel syndrome by attaching the device to the joints, which suggests its potential application in healthcare.","url":"https://doi.org/10.1002/smtd.202401730","authors":["Bae K","Kim M","Sim S","Kang Y","Kim J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1002/smtd.202401730","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.1111/ejn.70262","name":"Task Relevance Modulates Somatosensory Awareness Depending on Stimulus Intensity.","source":"europepmc","abstract":"","url":"https://doi.org/10.1111/ejn.70262","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1111/ejn.70262","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/biomimetics10030147","name":"Recent Developments and Applications of Tactile Sensors with Biomimetic Microstructures.","source":"pubmed","abstract":"Humans possess an innate ability to perceive a wide range of objects through touch, which allows them to interact effectively with their surroundings.

In this study, a low-vapor pressure liquid (LVPL) electrode TENG (LVPL-TENG) is presented that uses branched polyethyleneimine (bPEI) or deep eutectic solvent, choline chloride/glycerol (ChCl:Gly), to increase the stability of the TENGs at high temperatures.

Methods The proposed system employs a robust sensing layer to capture 12-dimensional multimodal data and synchronize physiological indicators with behavioral signals in real time. A novel Transformer-GCN hybrid model was developed to extract complex spatiotemporal dependencies for accurate action recognition and dynamic state analysis. In addition, a reinforcement learning module was incorporated to generate adaptive exercise prescriptions based on user progress.

Results The results demonstrated that the proposed framework achieved effective multimodal fusion and reliable action recognition in sports scenarios. After the 12-week intervention, participants in the intervention group showed a 20.1% increase in cardiorespiratory fitness ( VO 2 max), a 99.3% improvement in muscular endurance, and a sports injury rate maintained below 15%.

The objective of this research is to evaluate the effectiveness and functionality these navigation systems through a comparative analysis of recent technologies. For this purpose, the PRISMA 2020 methodology was used to perform a systematic literature review. After identification and screening, 58 articles published between 2019 and 2024 were selected from three academic databases: Dimensions (26 articles), Web of Science (18 articles), and Scopus (14 articles). Bibliometric analysis demonstrated a growing interest of the research community in the topic, with an average of 4.552 citations per published article. Even with the technological advances that have occurred in recent times, there is still a significant gap in the support systems for people with blindness due to the lack of digital accessibility and the scarcity of adapted support systems. This situation limits the autonomy and inclusion of people with blindness, so the need to continue developing technological and social solutions to ensure equal opportunities and full participation in society is evident. This study emphasizes the great advances with the integration of sensors such as high-precision GPS, ultrasonic sensors, Bluetooth, and various assistance apps for object recognition, obstacle detection, and trajectory generation, as well as haptic systems, which provide tactile information through wearables or actuators and improve spatial awareness. Current navigation algorithms were also identified in the review with methods including obstacle detection, path planning, and trajectory prediction, applied to technologies such as ultrasonic sensors, RGB-D cameras, and LiDAR for indoor navigation, as well as stereo cameras and GPS for outdoor navigation. It was also found that AI systems employ deep learning and neural networks to optimize both navigation accuracy and energy efficiency. Finally, analysis revealed that 79% of the 58 reviewed articles included experimental validation, 87% of which were on haptic systems and 40% on smartphones.

Despite advances in mechanical design leading to more sophisticated and dexterous artificial hands, difficulties persist in effectively controlling these prostheses due to the limitations posed by the muscle conditions of their users. These constraints result in a limited number of control inputs and a lack of sensory feedback. To address these issues, various semi-autonomous control strategies have been proposed, which integrate sensing technologies to complement traditional myoelectric control. Inspired by human grasping physiology, we propose a shared control strategy that divides grasp control into two levels: a high-level controller, operated by the user to initiate the grasp action, and a low-level controller, which ensures stability throughout the task. This work focuses specifically on slip detection methods, introducing improvements to the low-level controller to enable more autonomous grasping behavior during object holding. The proposed slip module uses distributed 3D force sensors across the artificial hand and integrates a friction cone strategy to ensure an appropriate shear-to-normal force ratio with bandpass filtering for establishing an initial stable grasp model without prior knowledge. Experimental evaluations consist of the comparison of this novel controller with conventional state-of-the-art approaches. Results demonstrate its efficacy in preventing slippage while requiring less grasping force than previous methods. Additionally, a qualitative validation was conducted to assess its responsiveness compared to human grasping reactions to unexpected weight changes, yielding positive outcomes.","url":"https://doi.org/10.1017/wtc.2025.10007","authors":["Matos J","Capsi-Morales P","Piazza C"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1017/wtc.2025.10007","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:51.650Z"},{"id":"pmid:42485554","name":"Emerging Multimodal Artificial Sensory Fusion Paradigms Toward Advanced Embodied Intelligence.","source":"pubmed","abstract":"In the endeavor of embodied intelligence to connect the digital world and physical reality, artificial multimodal sensory fusion has emerged as a cornerstone for endowing agents with robust perception and natural interaction capabilities.

Current standard methods, particularly India ink tattooing, demonstrate 15-30% failure rates for lesions less than 10 mm, leading to prolonged operative times, incomplete resections, and re-operations. Multiple emerging technologies promise improved localisation, yet comparative evidence remains fragmented. Objective : To map and characterise the current landscape of intraoperative marking and identification technologies for small colorectal tumour localisation during laparoscopic surgery, with emphasis on radiofrequency-based methods and alternative approaches, and to identify evidence gaps guiding future research. Methods : Following PRISMA-ScR guidelines, we systematically searched PubMed, Web of Science, and Scopus databases from January 2000 through December 2025 for studies evaluating tumour localisation technologies in colorectal cancer surgery, including primary tumour localisation during laparoscopic colectomy and localisation of colorectal liver metastases during hepatic surgery, or transferable anatomical applications with documented translational potential to colorectal surgery. Two independent reviewers screened all records, with discrepancies resolved through discussion and a third senior reviewer consulted for unresolved disagreements; data were extracted on technical performance, safety, feasibility, cost-effectiveness, usability, innovation potential, and evidence quality. Results : We included 89 studies comprising 18 colorectal-specific articles and 71 transferable/GI-adjacent studies. Detection success rates ranged from 71% to 100% across modalities. Near-infrared fluorescence with indocyanine green demonstrated the strongest clinical evidence with 75-100% detection across eight colorectal studies encompassing 2134 procedures and seamless workflow integration. Radiofrequency identification systems achieved 91.9-99% detection in feasibility studies with promising tissue penetration of 15-35 mm but limited colorectal validation. Electromagnetic navigation excelled in rigid organs with 85-98% success but showed degraded performance in mobile bowel at 71-75%. Critical evidence gaps included absent head-to-head comparative trials, non-standardised outcome metrics limiting cross-study comparability, and limited long-term safety data with only 14 studies providing follow-up exceeding six months. Conclusions : ICG fluorescence represents the most clinically mature technology identified, representing a priority candidate for colorectal-specific validation in challenging localisation scenarios. RFID systems demonstrate promising characteristics justifying prioritised research investment through adequately powered comparative trials. Future research must emphasise consortium-based comparative effectiveness studies, standardised outcome metrics, and integration with robotic and AI-assisted surgical platforms to accelerate clinical translation.","url":"https://pubmed.ncbi.nlm.nih.gov/42449734/","authors":["Fulea M","Mocan M","Murar M","Mocan B","Bințințan V"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jun 23","doi":"10.3390/diagnostics16131952","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.465Z"},{"id":"pmid:42290212","name":"3D-Printed Metamaterial-Based Soft Sensors: Materials, Design, and Fabrications.","source":"pubmed","abstract":"Additive manufacturing has enabled highly sophisticated three-dimensional soft bodies through material distribution, opening new possibilities for architected soft matter systems.

Touching different regions of the elastomeric surface displaces the viscous fluid, producing distinct pressure patterns that encode both touch position and force. These signals are decoded through a machine learning framework that integrates feature extraction, soft clustering, and adaptive neuro-fuzzy inference to achieve accurate localization and force estimation. We validate this concept through single-point touch localization and force estimation in a linear (1D) sensor and extend the same sensing principle to 2D tactile mapping by routing the channel across the surface using space-filling curves, while maintaining the same minimal hardware setup. This simple approach remains effective in environments where conventional electronic sensors often fail, such as underwater or in the presence of magnetic interference.","url":"https://pubmed.ncbi.nlm.nih.gov/42056132/","authors":["Goshtasbi A","Berghuis M","Parvaresh A","Murali Babu SP","Style RW","Rafsanjani A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1038/s41467-026-72497-3","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"pmid:41471468","name":"Multi-Task Deep Learning for Surface Metrology.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/41471468/","authors":["Kucharski D","Gąska A","Kowaluk T","Stępień K","Rępalska M","Gapiński B","Wieczorowski M","Nawotka M","Sobecki P","Sosinowski P","Tomasik J","Wójtowicz A"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025 Dec 8","doi":"10.3390/s25247471","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:40983692","name":"Detection of peripheral infusion-related infiltration and extravasation in neonates: a scoping review.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/40983692/","authors":["van Rens MFPT","Huis A","Hugill K","van der Lee R","de Boode WP"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Mar","doi":"10.1038/s41390-025-04367-5","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:40801439","name":"Bio-Inspired SA-FA Bionic Dual Receptor Electronic Skin for Intelligent Gesture and Material Cognition Systems Enhanced by Static-Dynamic Mutual Interaction.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/40801439/","authors":["Li H","Niu H","Kan H","Kim ES","Kim NY","Li Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025 Nov","doi":"10.1002/advs.202509740","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:40722399","name":"Aerosol Jet Printing for Neuroprosthetic Device Development.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/40722399/","authors":["De Waele L","Di Pietro M","Perilli S","Mantini E","Trevisan G","Simoncini M","Panella M","Betti V","Laffranchi M","Mantini D"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025 Jun 28","doi":"10.3390/bioengineering12070707","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:40625910","name":"Highly tough, crack-resistant and self-healable piezo-ionic skin enabled by dynamic hard domains with mechanosensitive ionic channel.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/40625910/","authors":["Wang X","Liu T","Sun F","Zhang J","Yao B","Xu J","Fu J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Sep","doi":"10.1002/smo.20240008","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:40212071","name":"Body-Integrated Ultrasensitive All-Textile Pressure Sensors for Skin-Inspired Artificial Sensory Systems.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/40212071/","authors":["Wang B","Shi Y","Li H","Hua Q","Ji K","Dong Z","Cui Z","Huang T","Chen Z","Wei R","Hu W","Shen G"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Sep","doi":"10.1002/smsc.202400026","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:39943472","name":"Adaptive Exoskeleton Device for Stress Reduction in the Ankle Joint Orthosis.","source":"pubmed","abstract":"Treating ankle fractures in athletes, commonly resulting from training injuries, remains a significant challenge.

In contrast, using transient electrical stimuli offers a promising alternative for generating tactile BCI control signals: somatosensory event-related potentials (sERPs). This study aimed to optimize the performance of a novel electrotactile BCI by employing advanced feature extraction and machine learning techniques on sERP signals for the classification of users' selective tactile attention. The experimental protocol involved ten healthy subjects performing a tactile attention task, with EEG signals recorded from five EEG channels over the sensory-motor cortex. We employed sequential forward selection (SFS) of features from temporal sERP waveforms of all EEG channels. We systematically tested classification performance using machine learning algorithms, including logistic regression, k-nearest neighbors, support vector machines, random forests, and artificial neural networks. We explored the effects of the number of stimuli required to obtain sERP features for classification and their influence on accuracy and information transfer rate. Our approach indicated significant improvements in classification accuracy compared to previous studies. We demonstrated that the number of stimuli for sERP generation can be reduced while increasing the information transfer rate without a statistically significant decrease in classification accuracy. In the case of the support vector machine classifier, we achieved a mean accuracy over 90% for 10 electrical stimuli, while for 6 stimuli, the accuracy decreased by less than 7%, and the information transfer rate increased by 60%. This research advances methods for tactile BCI control based on event-related potentials. This work is significant since tactile stimulation is an understudied modality for BCI control, and electrically induced sERPs are the least studied control signals in reactive BCIs. Exploring and optimizing the parameters of sERP elicitation, as well as feature extraction and classification methods, is crucial for addressing the accuracy versus speed trade-off in various assistive BCI applications where the tactile modality may have added value.","url":"https://pubmed.ncbi.nlm.nih.gov/39771785/","authors":["Novičić M","Djordjević O","Miler-Jerković V","Konstantinović L","Savić AM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Dec 17","doi":"10.3390/s24248048","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39727755","name":"Biomimetic Strategies of Slip Sensing, Perception, and Protection in Prosthetic Hand Grasp.","source":"pubmed","abstract":"This study develops biomimetic strategies for slip prevention in prosthetic hand grasps. The biomimetic system is driven by a novel slip sensor, followed by slip perception and preventive control. Here, we show that biologically inspired sensorimotor pathways can be restored between the prosthetic hand and users. A Ruffini endings-like slip sensor is used to detect shear forces and identify slip events directly. The slip information and grip force are encoded into a bi-state sensory coding that evokes vibration and buzz tactile sensations in subjects with transcutaneous electrical nerve stimulation (TENS). Subjects perceive slip events under various conditions based on the vibration sensation and voluntarily adjust grip force to prevent further slipping. Additionally, short-latency compensation for grip force is also implemented using a neuromorphic reflex pathway. The reflex loop includes a sensory neuron and interneurons to adjust the activations of antagonistic muscles reciprocally. The slip prevention system is tested in five able-bodied subjects and two transradial amputees with and without reflex compensation. A psychophysical test for perception reveals that the slip can be detected effectively, with a success accuracy of 96.57%. A slip protection test indicates that reflex compensation yields faster grasp adjustments than voluntary action, with a median response time of 0.30 (0.08) s, a rise time of 0.26 (0.03) s, an execution time of 0.56 (0.07) s, and a slip distance of 0.39 (0.10) cm.

As these technologies continue to advance, ensuring user-friendly interfaces and seamless interactions becomes more essential. For social robots to genuinely provide lasting value to humans, a favourable user experience (UX) emerges as an essential prerequisite. This article aimed to evaluate the usability of the MINI robot, highlighting its strengths and areas for improvement based on user feedback and performance. Materials and Methods : In a controlled lab setting, a mixed-method qualitative study was conducted with ten individuals aged 65 and above diagnosed with mild dementia (MD) and mild cognitive impairment (MCI). Participants engaged in individual MINI robot interaction sessions, completing cognitive tasks as per written instructions. Video and audio recordings documented interactions, while post-session System Usability Scale (SUS) questionnaires quantified usability perception. Ethical guidelines were followed, ensuring informed consent, and the data underwent qualitative and quantitative analyses, contributing insights into the MINI robot's usability for this demographic. Results : The study addresses the ongoing challenges that tasks present, especially for MD individuals, emphasizing the importance of user support. Most tasks require both verbal and physical interactions, indicating that MD individuals face challenges when switching response methods within subtasks. These complexities originate from the selection and use of response methods, including difficulties with voice recognition, tablet touch, and tactile sensors. These challenges persist across tasks, with individuals with MD struggling to comprehend task instructions and provide correct answers and individuals with MCI struggling to use response devices, often due to the limitations of the robot's speech recognition. Technical shortcomings have been identified. The results of the SUS indicate positive perceptions, although there are lower ratings for instructor assistance and pre-use learning. The average SUS score of 68.3 places device usability in the \"good\" category.

Forces applied to the dome change the curvature of the optical fibres, resulting in light attenuation. By changing the pressure within the dome and thereby adjusting the sensor's stiffness, we are able to modify the force measurement range. Results from our experimental study demonstrate that increasing the pressure inside the dome increases the force range whilst decreasing force sensitivity.

According to neurophysiological evidence, the easiest reliable way to render a virtual softness is to generate purely tactile (as opposed to kinaesthetic) feedback to be delivered via a finger-pulp-interfaced deformable surface. Moreover, it is necessary to control not only the skin indentation depth by applying quasi-static (non-vibratory) contact pressures, but also the skin contact area. This is typically impossible with available devices, even with those that can vary the contact area, because the latter cannot be controlled due to the complexity of sensing it at high resolutions. This causes indetermination on an important tactile cue to render softness. Here, we present a technology that allows the contact area to be open-loop controlled via personalised optical calibrations. We demonstrate the solution on a modified, pneumatic wearable tactile display of softness previously described by us, consisting of a small chamber containing a transparent membrane inflated against the finger pulp. A window on the device allowed for monitoring the skin contact area with a camera from an external unit to generate a calibration curve by processing photos of the skin membrane interface at different pressures. The solution was validated by comparisons with an ink-stain-based method. Moreover, to avoid manual calibrations, a preliminary automated procedure was developed. This calibration strategy may be applied also to other kinds of displays where finger pulps are in contact with transparent deformable structures.","url":"https://pubmed.ncbi.nlm.nih.gov/39460250/","authors":["Frediani G","Carpi F"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Oct 21","doi":"10.3390/s24206770","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39445517","name":"Microstructured Self-Healing Flexible Tactile Sensors Inspired by Bamboo Leaves.","source":"pubmed","abstract":"Wearable electronic devices with multifunctions such as flexible, integrated, and self-powered play a crucial role in the fields of health monitoring, motion monitoring, and human-computer interaction. However, their core basic components, flexible pressure sensors, face challenges including poor long-term stability and insufficient real-time sensing accuracy. In order to solve the challenges of long-term, stable, and accurate sensing of the sensor, this paper prepares polydimethylsiloxane (SHPDMS) with intrinsic self-healing property and designs a high-sensitivity self-healing capacitive flexible pressure sensor with dual microstructures (grating microstructured electrodes and microporous dielectric layer) as the substrate based on SHPDMS. Specifically speaking, the self-healing of the sensor under mild conditions was realized by introducing reversible imine bonds with low bonding energy into the polydimethylsiloxane (PDMS) flexible substrate, which solved the problem of the material's long-term service durability. A grating-like microstructure was introduced into the flexible electrode by using a spotted bamboo taro leaf as a template, and a dual microstructure sensor was constructed by combining it with a microporous dielectric layer doped with single-walled carbon nanotubes. This way reduces the elastic modulus of the dielectric layer, improves the dielectric constant of the sensor under loading, and thus significantly improves the sensor's sensitivity and extends the measurement accuracy in a low-stress range. The prepared self-healing flexible sensor achieves a sensitivity of 3.6 kPa -1 , a minimum detection limit of 5 Pa, a response recovery time of less than 80 ms, and stability over 5000 cycles, which exceeds most previously reported silicone rubber-based capacitive flexible sensors.","url":"https://pubmed.ncbi.nlm.nih.gov/39445517/","authors":["Sun P","Fang Z","Sima W","Niu C","Yuan T","Yang M","Liu Q","Tang W"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Nov 6","doi":"10.1021/acsami.4c15197","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39431947","name":"Directional Characteristic Enhancement of an Omnidirectional Detection Sensor Enabled by Strain Partitioning Effects in a Periodic Composite Hole Substrate.","source":"pubmed","abstract":"An omnidirectional stretchable strain sensor with high resolution is a critical component for motion detection and human-machine interaction. It is the current dominant solution to integrate several consistent units into the omnidirectional sensor based on a certain geometric structure. However, the excessive similarity in orientation characteristics among sensing units restricts orientation recognition due to their closely matched strain sensitivity. In this study, based on strain partition modulation (SPM), a sensitivity anisotropic amplification strategy is proposed for resistive strain sensors. The stress distribution of a sensitive conductive network is modulated by structural parameters of the customized periodic hole array introduced underneath the elastomer substrate. Meanwhile, the strain isolation structures are designed on both sides of the sensing unit for stress interference immune. The optimized sensors exhibit excellent sensitivity (19 for 0-80%; 109 for 80%-140%; 368 for 140%-200%), with nearly a 7-fold improvement in the 140%-200% interval compared to bare elastomer sensors. More importantly, a sensing array composed of multiple units with different hole configurations can highlight orientation characteristics with amplitude difference between channels reaching up to 29 times. For the 48-class strain-orientation decoupling task, the recognition rate of the sensitivity-differentiated layout sensor with the lightweight deep learning network is as high as 96.01%, superior to that of 85.7% for the sensitivity-consistent layout.

Incorrect grading can easily lead to spoiled and degraded fruits entering the market, reducing consumers' confidence in purchasing. At the same time, it is easy to cause the fruit supply chain to reduce profits, unreasonable resource allocation, and related practitioners' income. The current mainstream machine vision grading and manual grading in the production line have dilemmas such as susceptibility to environmental interference, inconsistent grading standards, high cost, and labor shortage. To overcome these problems, this study proposes an integrated flexible tactile sensing array (3 &#xd7; 4) manipulator for efficient, stable, low-cost, and accurate ripeness and size grading of kiwifruit. The flexible sensing manipulator grasps the kiwifruit, detects the hardness of the kiwifruit by relying on tactile sensing, and determines the ripeness level based on the hardness. The size of the kiwifruit is also differentiated according to whether there is a significant change in the resistance of the topmost sensing unit of the flexible pressure sensor array. The 0, 1, 2, 3, 4, and 5 anomalies that may occur in actual production were tested and combined with machine learning KNN, SVM, and RF algorithms for data modeling and grading. The results show that the lowest accuracy of 0, 1, 2, 3, 4, and 5 possible outliers is 86.67% (KNN), 95.83% (SVM), and 92.5% (RF), respectively. KNN has the lowest classification effect, and SVM has the best. This study overcomes the drawbacks of inefficient destructive detection and unstable manual detection and makes up for the vulnerability of single machine vision to interference from environmental factors.

Here, we address this issue by utilizing the unique polarization chemistry of conjugated polymers for the first time and propose a new type of bioinspired, passive, and bio-friendly tactile sensors for resolving both static and dynamic stimuli. Specifically, to emulate the polarization process of natural sensory cells, conjugated polymers (including poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), polyaniline, or polypyrrole) are controllably polarized into two opposite states to create artificial potential differences. The controllable and reversible polarization process of the conjugated polymers is fully in situ characterized. Then, a micro-structured ionic electrolyte is employed to imitate the natural ion channels and to encode external touch stimulations into the variation in potential difference outputs. Compared with the currently existing tactile sensing devices, the developed tactile sensors feature distinct characteristics including fully organic composition, high sensitivity (up to 773&#xa0;mV&#xa0;N -1 ), ultralow power consumption (nW), as well as superior bio-friendliness.

The Inception-ResNet-v2 architecture with transfer learning categorized the cracks in MZ crowns into five groups: labial, palatal, incisal, left, and right. After 2000 epochs, with a learning rate of 0.0001, the model achieved an accuracy of 99.4667%, demonstrating that deep learning significantly improved the localization of cracks in MZ crowns.

Twenty-seven young adults (females, 15) were continuously and passively stimulated with a random series of gentle brushes on single fingers of each hand, which were covered from view. Thus, tactile stimulations were unique for each participant and stimulated fingers. An encoding model measured the degree of synchronization between brain activity and continuous tactile input, generating a temporal response function (TRF). Brain topographies associated with the encoding of each finger stimulation showed a contralateral response at central sensors starting at 50&#x2005;ms and peaking at &#x223c;140&#x2005;ms of lag, followed by a bilateral response at &#x223c;240&#x2005;ms.

However, the low glass transition temperature of flexible substrates poses a challenge as it is incompatible with the high-temperature annealing required for electrode fabrication, thereby limiting the performance of flexible electronic devices. In this study, we address these limitations by proposing a novel flexible device manufacturing process that combines adhesive printing patterning with a transfer printing technology. By employing poly(vinylidene fluoride) (PVDF)/graphene nitride (GCN) as the transfer substrate and dielectric layer, we successfully fabricated a high-performance dual-mode touch sensor on a large scale. The successful development of this dual-mode sensor can be attributed to two key factors: the construction of a robust hydrogen-bonding network between the PVDF/GCN dielectric layer and the carbon electrode and the ability of GCN to restrict the movement of PVDF molecular chains within the dielectric layer. This restriction reduces the overall polarization of the film, enabling the formation of a complete device structure with a highly sensitive edge electric field. The noncontact sensors developed in this study are fully printable into sensor arrays and can be seamlessly integrated with internet of things technology for wearable applications. These sensors exhibit exceptional tactile response and facilitate effective human-machine interactions over extended distances, underscoring their significant potential in fields such as healthcare and artificial intelligence.","url":"https://pubmed.ncbi.nlm.nih.gov/39231260/","authors":["Zheng S","Cong C","Jiang F","Yu S","Li B","Sun F","Zheng X","Diao B","Joo SW","Li R","Kim SH","Li X"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Sep 18","doi":"10.1021/acsami.4c10842","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39204865","name":"SmartVR Pointer: Using Smartphones and Gaze Orientation for Selection and Navigation in Virtual Reality.","source":"pubmed","abstract":"Some of the barriers preventing virtual reality (VR) from being widely adopted are the cost and unfamiliarity of VR systems. Here, we propose that in many cases, the specialized controllers shipped with most VR head-mounted displays can be replaced by a regular smartphone, cutting the cost of the system, and allowing users to interact in VR using a device they are already familiar with. To achieve this, we developed SmartVR Pointer, an approach that uses smartphones to replace the specialized controllers for two essential operations in VR: selection and navigation by teleporting. In SmartVR Pointer, a camera mounted on the head-mounted display (HMD) is tilted downwards so that it points to where the user will naturally be holding their phone in front of them. SmartVR Pointer supports three selection modalities: tracker based, gaze based, and combined/hybrid. In the tracker-based SmartVR Pointer selection, we use image-based tracking to track a QR code displayed on the phone screen and then map the phone's position to a pointer shown within the field of view of the camera in the virtual environment. In the gaze-based selection modality, the user controls the pointer using their gaze and taps on the phone for selection. The combined technique is a hybrid between gaze-based interaction in VR and tracker-based Augmented Reality. It allows the user to control a VR pointer that looks and behaves like a mouse pointer by moving their smartphone to select objects within the virtual environment, and to interact with the selected objects using the smartphone's touch screen. The touchscreen is used for selection and dragging. The SmartVR Pointer is simple and requires no calibration and no complex hardware assembly or disassembly. We demonstrate successful interactive applications of SmartVR Pointer in a VR environment with a demo where the user navigates in the virtual environment using teleportation points on the floor and then solves a Tetris -style key-and-lock challenge.","url":"https://pubmed.ncbi.nlm.nih.gov/39204865/","authors":["McDonald B","Zhang Q","Nanzatov A","Peña-Castillo L","Meruvia-Pastor O"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Aug 10","doi":"10.3390/s24165168","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39194475","name":"Bio-Inspired Strategies Are Adaptable to Sensors Manufactured on the Moon.","source":"pubmed","abstract":"Bio-inspired strategies for robotic sensing are essential for in situ manufactured sensors on the Moon.

Terrestrial approaches to sensor design cannot be accommodated within the severe limitations imposed by the material resources and expected manufacturing competences on the Moon. Displacement and strain sensors may be constructed as potentiometers with aluminium extracted from anorthite. Anorthite is also a source of silica from which quartz may be manufactured. Thus, piezoelectric sensors may be constructed. Silicone plastic (siloxane) is an elastomer that may be derived from lunar volatiles. This offers the prospect for tactile sensing arrays. All components of photomultiplier tubes may be constructed from lunar resources. However, the spatial resolution of photomultiplier tubes is limited so only modest array sizes can be constructed. This requires us to exploit biomimetic strategies: (i) optical flow provides the visual navigation competences of insects implemented through modest circuitry, and (ii) foveated vision trades the visual resolution deficiencies with higher resolution of pan-tilt motors enabled by micro-stepping.

Herein, we report an approach toward developing electrical hysteresis- and cross-interference-free nontactile e-skin using liquid polyisoprene with an ultralow concentration of multiwalled carbon nanotubes (&#x3d5; = 0.006 volume fraction) by leveraging the stencil printing technique. The impact of cross-linking the samples was studied. Uncross-linked samples demonstrated higher electrical conductivity than the cross-linked samples. A coarse-grained phenomenological model with molecular dynamics simulation was utilized to investigate filler network formation and percolation that dictate the conductivity of uncross-linked and cross-linked samples. Simulation studies supported the fidelity of the experimental findings. The uncross-linked e-skin demonstrated a higher temperature sensitivity (-1.103%/&#xb0;C) than the cross-linked e-skin (-0.320%/&#xb0;C) in the thermal conduction mode. Despite the superior sensitivity of the uncross-linked e-skin, the cross-linked systems demonstrated superior cyclic stability (35 thermal cycles), ensuring reliable sensor readings over extended usage. Judicious choice of encapsulant warranted the cross-linked e-skin sensor to nullify the impact of moisture on signal output, thereby providing cross-interference-free results. The optimized e-skin sample retained a similar thermal sensitivity even when used in the nontactile mode.

To capture frequencies in the human hearing range, commercial microphones typically have a sampling rate of over 40 kHz. These accessible acoustic technologies are not yet widely adopted for the explicit purpose of giving robots a sense of touch. Some researchers have used sound to sense tactile information, both monitoring ambient soundscape and with embedded speakers and microphones to measure sounds within structures. However, these options commonly do not provide a direct measure of steady state force or require electronics integrated somewhere near the contact location. In this work, we present AcousTac, an acoustic tactile sensor for electronics-free, force-sensitive soft skin. Compliant silicone caps and plastic tubes compose the resonant chambers that emit pneumatic-driven sound measurable with a conventional off-board microphone. The resulting frequency changes depend on the external loads on the compliant endcaps. The compliant cap vibrates with the resonant pressure waves and is a nonidealized boundary condition, initially producing a nonmonotonic force response. We characterize two solutions-adding a distal hole and mass to the cap-resulting in monotonic and nonhysteretic force readings with this technology. We can tune each AcousTac taxel to specific force and frequency ranges, based on geometric parameters including tube length, and thus uniquely sense each taxel simultaneously in an array. We demonstrate AcousTac's functionality on two robotic systems: a 4-taxel array and a 3-taxel astrictive gripper. Simple to implement with off-the-shelf parts, AcousTac is a promising concept for force sensing on soft robotic surfaces, especially in situations where electronics near the contact are not suitable.

Insects often use slender, lightweight, and flexible links as sensing antennae. These antennae have a muscle-endowed base that changes their orientation and an organ that senses the applied force and moment, enabling active sensing. Sensing antennae detect obstacles through contact during motion and even recognize objects. They can also push obstacles. In all these tasks, force control of the antenna is crucial. The objective of our research is to develop a haptic robotic system based on a sensing antenna, consisting of a very lightweight and slender flexible rod. In this context, the work presented here focuses on the force control of this device. To achieve this, (a) we develop a dynamic model of the antenna that moves under gravity and maintains point contact with an object, based on lumped-mass discretization of the rod; (b) we prove the robust stability property of the closed-loop system using the Routh stability criterion; and (c) based on this property, we design a robust force control system that performs efficiently regardless of the contact point with the object. We built a mechanical device replicating this sensing organ. It is a flexible link connected at one end to a 3D force-torque sensor, which is attached to a mechanical structure with two DC motors, providing azimuthal and elevation movements to the antenna. Our experiments in contact situations demonstrate the effectiveness of our control method.","url":"https://pubmed.ncbi.nlm.nih.gov/39056855/","authors":["Haro-Olmo MI","Mérida-Calvo L","Feliu-Talegón D","Feliu-Batlle V"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Jul 7","doi":"10.3390/biomimetics9070414","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39056155","name":"Unveiling Gating Behavior in Piezoionic Effect: toward Neuromimetic Tactile Sensing.","source":"pubmed","abstract":"The human perception system's information processing is intricately linked to the nonlinear response and gating effect of neurons. While piezoionics holds potential in emulating the pressure sensing capability of biological skin, the incorporation of information processing functions seems neglected. Here, ionic gating behavior in piezoionic hydrogels is uncovered as a notable extension beyond the previously observed linear responses. The hydrogel can generate remarkably high voltages (700&#xa0;mV) and currents (7&#xa0;mA) when indentation forces surpass the threshold. Through a comprehensive analysis involving simulations and experimental investigations, it is proposed that the gating behavior emerges due to significant diffusion differences between cations and anions. To showcase the practical implications of this breakthrough, the piezoionic hydrogels are successfully integrated with prostheses and robot hands, demonstrating that the gating effect enables accurate discrimination between gentle and harsh touch. The advancement in neuromimetic tactile sensing has significant potential for emerging applications such as humanoid robotics and biomedical engineering, offering valuable opportunities for further development of embodied neuromorphic intelligence.","url":"https://pubmed.ncbi.nlm.nih.gov/39056155/","authors":["Wang S","Yang T","Zhang D","Hua Q","Zhao Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Sep","doi":"10.1002/adma.202405391","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39045279","name":"Head tracking using an optical soft tactile sensing surface.","source":"pubmed","abstract":"This research proposes a sensor for tracking the motion of a human head via optical tactile sensing.

Previous works have included robotics grippers to mimic the sensory features of human skin, that used monochrome cameras and depth cameras. Tactile sensing has shown advantages in feedback-based interactions between robots and their environment. The methodology in this paper is utilised to track motion of objects in physical contact with these sensors to replace external camera based motion capture systems. Our immediate application is related to detection of human head motion during radiotherapy procedures. The motion was analysed in two degrees of freedom, respective to the tactile sensor (translational in z-axis, and rotational around y-axis), to produce repeatable and accurate results. The movements were stimulated by a robot arm, which also provided ground truth values from its end-effector. The fibrescope was implemented to ensure the device's compatibility with electromagnetic waves. The cameras and the ground truth values were time synchronised using robotics operating systems tools. Image processing methods were compared between grayscale and binary image sequences, followed by motion tracking estimation using deterministic approaches. These included Lukas-Kanade Optical Flow and Simple Blob Detection, by OpenCV. The results showed that the grayscale image processing along with the Lukas-Kanade algorithm for motion tracking can produce better tracking abilities, although further exploration to improve the accuracy is still required.","url":"https://pubmed.ncbi.nlm.nih.gov/39045279/","authors":["Gandhi B","Mihaylova L","Dogramadzi S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.3389/frobt.2024.1410858","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39023228","name":"Stretchable Iontronic Tactile Sensing Fabric.","source":"pubmed","abstract":"The iontronic tactile sensing modality has garnered significant attention due to its exceptional sensitivity, immunity to noise, and versatility in materials.

Incorporating a stretchable tactile sensing implement could enhance the wear comfortability by preventing relative movement and ensuring intimate contact between the sensor and the skin. The research focuses on the development of a stretchable iontronic pressure sensing (SIPS) fabric for monitoring diverse aspects of body health and movement in wearable applications. The tactile sensing structure is generated at the iontronic interface between highly stretchable ionic and conductive fabrics. In particular, the ionic fabric is prepared by coating a layer of polyurethane/ionic liquid gel onto a Spandex fabric. To showcase its remarkable sensitivity, stretchability, and ability to detect diverse body information, several application scenarios have been demonstrated including an elastic wristband for precise pulse wave detection, a flexible belt with multitactile sensing channels for respiration and motion tracking purposes, and a stretchable fabric cuff equipped with a high-resolution sensing array comprising 32 &#xd7; 32 units for accurate gesture recognition.","url":"https://pubmed.ncbi.nlm.nih.gov/39023228/","authors":["Li B","Luo Z","Gong L","Ge R","Wang M","Zhu Y","Cheng Y","Li S","Peng T","Chang Y"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Aug 14","doi":"10.1021/acsami.4c07887","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39001022","name":"Wavelet Transforms Significantly Sparsify and Compress Tactile Interactions.","source":"pubmed","abstract":"As higher spatiotemporal resolution tactile sensing systems are being developed for prosthetics, wearables, and other biomedical applications, they demand faster sampling rates and generate larger data streams. Sparsifying transformations can alleviate these requirements by enabling compressive sampling and efficient data storage through compression. However, research on the best sparsifying transforms for tactile interactions is lagging. In this work we construct a library of orthogonal and biorthogonal wavelet transforms as sparsifying transforms for tactile interactions and compare their tradeoffs in compression and sparsity. We tested the sparsifying transforms on a publicly available high-density tactile object grasping dataset (548 sensor tactile glove, grasping 26 objects). In addition, we investigated which dimension wavelet transform-1D, 2D, or 3D-would best compress these tactile interactions. Our results show that wavelet transforms are highly efficient at compressing tactile data and can lead to very sparse and compact tactile representations. Additionally, our results show that 1D transforms achieve the sparsest representations, followed by 3D, and lastly 2D. Overall, the best wavelet for coarse approximation is Symlets 4 evaluated temporally which can sparsify to 0.5% sparsity and compress 10-bit tactile data to an average of 0.04 bits per pixel. Future studies can leverage the results of this paper to assist in the compressive sampling of large tactile arrays and free up computational resources for real-time processing on computationally constrained mobile platforms like neuroprosthetics.","url":"https://pubmed.ncbi.nlm.nih.gov/39001022/","authors":["Slepyan A","Zakariaie M","Tran T","Thakor N"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Jun 29","doi":"10.3390/s24134243","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"pmid:39000913","name":"A Coupled Double-Layer Electrical Impedance Tomography-Based Sensing Skin for Pressure and Leak Detection.","source":"pubmed","abstract":"There is an extensive need for surface sensors for applications such as tactile sensing for robotics, damage and strain detection for structural health monitoring and leak detection for buried structures.

However, the ridges on tactile sensors are susceptible to abrasion damage from repeated use. To date, the healing function of abraded ridges has not been proposed, and its effectiveness needs to be demonstrated. In this study, we investigated whether the signal detection capabilities of a sensor with abraded epidermal ridges could be restored by healing the ridges using polyvinyl chloride plastisol as the sensor material. We developed a prototype tactile sensor with an embedded strain gauge, which was used to repeatedly scan roughness specimens. After more than 1000 measurements, we observed significant deterioration in the sensor's output signal level. The ridges were then reshaped using a mold with a heating function, allowing the sensor to partially regain its original signal levels.

Recent advances in flexible electronics have created tactile sensors that effectively replicate slowly adapting (SA) and rapidly adapting (RA) mechanoreceptors. However, the influence of dermatoglyphic structures on tactile signal transmission, such as the effect of fingerprint ridge filtering on friction-induced vibration frequencies, remains unexplored. A novel multi-layer flexible sensor with an artificially synthesized skin surface capable of replicating arbitrary fingerprints is developed. This sensor simultaneously detects pressure (SA response) and vibration (RA response), enabling texture recognition. Fingerprint ridge patterns from notable historical figures - Rosa Parks, Richard Nixon, Martin Luther King Jr., and Ronald Reagan - are fabricated on the sensor surface. Vibration frequency responses to assorted fabric textures are measured and compared between fingerprint replicas. Results demonstrate that fingerprint topography substantially impacts skin-surface vibrational transmission. Specifically, Parks' fingerprint structure conveyed higher frequencies more clearly than those of Nixon, King, or Reagan. This work suggests individual fingerprint ridge morphological variation influences tactile perception and can confer adaptive advantages for fine texture discrimination.

Among various sensors, the demand for force sensors that can recognize physical phenomena in 3D space has notably increased. Recent research has focused on developing energy harvesting methods for sensors to address their maintenance problems. Triboelectric nanogenerator (TENG) based force sensors are a promising solution for converting external motion into electrical signals. However, conventional TENG‐based force sensors that use the signal peak can negatively affect data accuracy. In this study, a Scott–Russell linkage‐inspired TENG (SRI‐TENG) is developed. The SRI‐TENG has completely separate signal generation and measurement sections, and the number of peaks in the electrical output is measured to prevent disturbing output signals. In addition, the lubricant liquid enhances durability, enabling stable force signal measurements for 270 000 cycles. The SRI system demonstrates consistent peak counts and high accuracy across different contacting surfaces, indicating that it can function as a contact material‐independent self‐powered force sensor. Furthermore, using a deep learning method, it is demonstrated that it can function as a multimodal sensor by realizing the tactile properties of various

Tactile Sensing of Soft Machines.","source":"pubmed","abstract":"The somatosensory system is crucial for living beings to survive and thrive in complex environments and to interact with their surroundings. Similarly, rapidly developed soft robots need to be aware of their own posture and detect external stimuli. Bending and force sensing are key for soft machines to achieve embodied intelligence. Here, we present a soft inductive bimodal sensor (SIBS) that uses the strain modulation of magnetic permeability and the eddy-current effect for simultaneous bidirectional bending and force sensing with only two wires. The SIBS is made of a flexible planar coil, a porous ferrite film, and a soft conductive film. By measuring the inductance at two different frequencies, the bending angle and force can be obtained and decoupled. Rigorous experiments revealed that the SIBS can achieve high resolution (0.44° bending and 1.09 mN force), rapid response, excellent repeatability, and high durability. A soft crawling robot embedded with one SIBS can sense its own shape and interact with and respond to external stimuli. Moreover, the SIBS is demonstrated as a wearable human-machine interaction to control a crawling robot via wrist bending and touching. This highlights that the SIBS can be readily implemented in diverse applications for reliable bimodal sensing.","url":"https://pubmed.ncbi.nlm.nih.gov/38868951/","authors":["Peng Y","Wu H","Wang Z","Wang Y","Wang H","Yulian Peng","Houping Wu","Zhengyan Wang","Yufeng Wang","Hongbo Wang"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Dec","doi":"10.1089/soro.2023.0249","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"pmid:38855203","name":"Application of multimodality perception scene construction based on Internet of Things (IoT) technology in art teaching.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/38855203/","authors":["Wang H","Wang Y","Jin J"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.7717/peerj-cs.2047","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:38845755","name":"Evaluating the Efficacy of Cervical Tactile Ultrasound Technique as a Predictive Tool for Spontaneous Preterm Birth.","source":"pubmed","abstract":"","url":"https://pubmed.ncbi.nlm.nih.gov/38845755/","authors":["Egorov V","Rosen T","Hill J","Khandelwal M","Kurtenoks V","Francy B","Sarvazyan N"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 May","doi":"10.4236/ojog.2024.145067","addedAt":"2026-08-31T06:34:48.950Z","updatedAt":"2026-08-31T06:34:48.950Z"},{"id":"pmid:38834723","name":"Can you feel the force just right?

BioTac is a commonly used tactile sensor that enables robots to perceive and respond to physical tactile stimuli. However, the sensor's non-linearity poses challenges in simulating its behavior. In this paper, we first investigate a BioTac simulation that uses temperature, force, and contact point positions to predict the sensor outputs. We show that training with BioTac temperature readings does not yield accurate sensor output predictions during deployment. Consequently, we tested three alternative models, i.e., an XGBoost regressor, a neural network, and a transformer encoder. We train these models without temperature readings and provide a detailed investigation of the window size of the input vectors. We demonstrate that we achieve statistically significant improvements over the baseline network. Furthermore, our results reveal that the XGBoost regressor and transformer outperform traditional feed-forward neural networks in this task.

The facility was well‑ventilated to ensure optimal air exchange and maintain the micro-environment consistent with recognized housing guidelines.1.2.3. Modeling and randomization 1.2.3.1. Modeling A total of 54 eight-month-old female Sprague–Dawley rats underwent a 7-day acclimatization period. Rats were randomly assigned by using a random-number table allocated to the blank control group (NC; n = 8) or the sarcopenia model group (n =46). The sarcopenia model was established via bilateral ovariectomy (OVX) followed by dexamethasone (DXM) administration, as follows: ● Preoperative preparation: 2 hours of fasting (no food or water). ● Anesthesia: Intramuscular injection of Zoletil® 100 at a dose of 30 mg/kg. ● Surgical procedure: The rat was placed supine, and the abdominal area was shaved and disinfected with povidone-iodine, then covered with sterile gauze. A 1 cm incision was made — 1 cm dorsal to the third pair of nipples — from tail to head. Each ovary was ligated at both ends and excised. Then the incision was closed in layers. ● Postoperative care: Rats were kept warm and only returned to ad libitum feeding and drinking upon recovery. On the day of surgery and for the subsequent two days, each received an intramuscular injection of penicillin G (400,000 U) daily to prevent infection. ● The NC group underwent a sham surgery, where the ovaries were located but not removed, and the abdomen was sutured in layers. ● Seven days after OVX, rats in the model group received subcutaneous dexamethasone (5 mg/kg) once daily for 7 consecutive days. Rats in the NC group received an equal volume of 0.9% saline on the same schedule. ● Model validation: Body weight, grip strength, and rotarod performance were measured before and after model induction to confirm successful sarcopenia induction. During induction, four rats died, and one was excluded due to hind limb injury from improper blood flow restriction training. The final number of effective animals was 54, which were randomly re-assigned using a random‑number table into: ● NC group (n = 8)● Model control (DM) (n = 46) 1.2.3.2. Randomization and grouping Prior to model induction, rats were grouped into Blank Control (NC, n = 8) and Model Control (DM, n = 46). After confirming successful model induction, the 46 sarcopenia-model rats were further randomized (via random-number table) into different groups, the allocation results presented in (Table 1.).

Because of their simplified design, they are unable to reproduce the dexterity of human hands when manipulating a wide range of objects. While the control of humanoid hands evolved greatly, hardware platforms still lack capabilities, particularly in tactile sensing and providing soft contact surfaces. In this work, we present a method that equips the skeleton of a tendon-driven humanoid hand with a soft and sensorized tactile skin. Multi-material 3D printing allows us to iteratively approach a cast skin design which preserves the robot's dexterity in terms of range of motion and speed.

In contrast, humans learn these properties through interactive multi-sensor exploration. This work proposes fusing visual and tactile observations into a unified Gaussian Process Distance Field (GPDF) representation for active perception of object properties. While primarily focusing on geometry, this approach also demonstrates potential for modeling surface properties beyond geometry. The GPDF encodes signed distance using point cloud, analytic gradient and Hessian, and surface uncertainty estimates, which are attributes that common neural network shape representation lack. By utilizing a point cloud to construct a distance function, GPDF does not need extensive pretraining on large datasets and can incorporate observations by aggregation. Starting with an initial visual shape estimate, the framework iteratively refines the geometry by integrating dense vision measurements using differentiable rendering and tactile measurements at uncertain surface regions. By quantifying multi-sensor uncertainties, it plans exploratory motions to maximize information gain for recovering precise 3D structures. For the real-world robot experiment, we utilize the Franka Research 3 robot manipulator, which is fixed on a table and has a customized DIGIT tactile sensor and an Intel Realsense D435 RGBD camera mounted on the end-effector. In these experiments, the robot explores the shape and properties of objects assumed to be static and placed on the table. To improve scalability, we investigate approximation methods like inducing point method for Gaussian Processes. This probabilistic multi-modal fusion enables active exploration and mapping of complex object geometries, extending potentially beyond geometry.","url":"https://doi.org/10.48550/arxiv.2507.05522","authors":["Choi, Ho Jin","Figueroa, Nadia"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2507.05522","addedAt":"2026-08-31T06:34:48.951Z","updatedAt":"2026-08-31T06:34:48.951Z"},{"id":"doi:10.48550/arxiv.2505.16062","name":"WaveTouch: Active Tactile Sensing Using Vibro-Feedback for Classification of Variable Stiffness and Infill Density Objects","source":"datacite","abstract":"The perception and recognition of the surroundings is one of the essential tasks for a robot.

One of the key innovations in this work is the use of sputtered thin-film metal electrodes, which significantly reduce both the structural dimensions and electrode resistance of DEAs compared to traditional screen-printed electrodes. This advancement enables the creation of a compact 3x3 sensing array, which is integrated with a single DEA based feedback element. To enhance tactile feedback, the DEA element is constructed with multiple layers of thin-film electrode-based dielectric elastomers. The low-resistance electrodes also enable efficient high-frequency stimulation of the actuator, improving performance. The high mechanical flexibility of these functional components makes them ideal for textile integration. By combining a dielectric elastomer sensing array with a multilayer DEA actuation unit, a modular, textile-integrated user-interaction interface is achieved. On a microcontroller the logic necessary for the two elements to interact is implemented, enabling bidirectional communication with the user. The innovative manufacturing process allows for the stacking of eight active sputtered dielectric elastomer layers, creating an actuator with crimped electrical connections that ensures high efficiency and strong haptic feedback.

Previous studies have demonstrated hardness classification using Commercial Off-The-Shelf (COTS) sensors but lacked robotic integration considerations. This study explores the integration of multiple COTS sensors, inspired by mechanoreceptors, for classifying material hardness. The sensors were used to classify objects into three categories—hard, soft, and flexible—based on the qualitative Shore hardness scale. The aim was to identify the optimal sensor topology configuration that delivers high accuracy, using machine learning algorithms provided in the literature. The results suggest that the Random Forest Classifier is the most suitable algorithm, showcasing accuracies ranging from 90% to 98.7%, across various sensor topologies. The ‘PFV’ topology, comprising a potentiometer (P), force sensor (F), and vibration sensor (V), achieved the highest accuracy of 98.7%, while the ‘FPV’ and ‘FVP’ recorded accuracies between 96% and 97.5%. The topology of FPV and FVP have the most closely related configuration to that of mechanoreceptors; however, the results show that PFV outperforms this configuration. While the PFV topology marginally outperforms the mechanoreceptor-inspired configurations, the results demonstrate that bio-inspired sensor arrangements provide a robust solution for hardness classification in robotics. The PFV topology performs better than FPV in terms of prediction speed, with an average prediction time of 8.31 ms (millisecond) for PFV versus 13.93 ms for FPV. PFV and FPV achieved 12 and 13 correct predictions, respectively, out of 18 objects. The faster prediction times of PFV make it particularly advantageous for applications requiring quick and accurate decision-making for robotic applications.","url":"https://doi.org/10.3390/electronics14040674","authors":["Yash Sharma","Claire Guo","Matthew Beatty","Laura Justham","Pedro Ferreira"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-12T08:05:42Z","doi":"10.3390/electronics14040674","addedAt":"2026-08-31T06:34:50.036Z","updatedAt":"2026-08-31T06:34:50.036Z"},{"id":"doi:10.2139/ssrn.5217560","name":"A Soft Tactile Sensor Based on Contact-Electrification Difference for Simultaneous Stiffness Discrimination and Material Identification","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5217560","authors":["Yangyang Li","Bo Pang","Zhixin Wang","Han Fang","Ganguang Yang","Tianzhao Bu","Hao Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-04-15T04:41:19Z","doi":"10.2139/ssrn.5217560","addedAt":"2026-08-31T06:34:50.036Z","updatedAt":"2026-08-31T06:34:50.036Z"},{"id":"doi:10.2139/ssrn.5796974","name":"Biomimetic Tactile Sensor for Dynamic-Static Perception Based on Piezoionic and Piezoresistive Effects","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5796974","authors":["Huanyu Liu","Jiaming Fan","Yongqi Kuang","Jin Xu","Qizhao Liang","Zhimeng Liu","Jun-Wei Zha","Yunhui Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-11-24T17:33:52Z","doi":"10.2139/ssrn.5796974","addedAt":"2026-08-31T06:34:50.036Z","updatedAt":"2026-08-31T06:34:50.036Z"},{"id":"doi:10.1109/transducers61432.2025.11109856","name":"Demonstration of &gt;30K-Cycle Stability of a Printed-Circuit-Board-Based Network Tactile Sensor with Embedded Sensor Platform LSI","source":"crossref","abstract":"","url":"https://doi.org/10.1109/transducers61432.2025.11109856","authors":["Jorge E.

The purpose of this study is to evaluate the performance of two types of capacitive tactile sensors with different structures, designed for mounting on robotic grippers. Design/methodology/approach An experiment was conducted to measure the self-capacitance response to normal force when the sensors encountered different materials, including metal, cotton, plastic, aluminium, rubber and clay. The change in capacitance against the normal force applied was analysed to determine the sensitivity of each sensor for different materials and various force ranges. Findings Experimental results show that the sensitivity of the two types of sensors varies significantly across different materials and measurement ranges, with values ranging from 8.97%/N to 108.31%/N. The sensors exhibit different responses to materials with varying hardness, which is critical for robotic grippers to adapt their interaction strategies based on material properties.

Dynamic Subtle Stimuli Tactile Perception: A Deep Learning‐Enhanced Super‐Resolution Tactile Sensor Array with Rapid Response","source":"crossref","abstract":"Human skin's touch perception, mediated by mechanoreceptors, can perceive tactile stimuli with a spatial resolution higher than the average spacing between mechanoreceptors, known as super‐resolution. This characteristic enables its sensitivity to both stimulus location and velocity. However, existing robotic tactile sensors lag behind human tactile perception, failing to achieve high spatial resolution and rapid response simultaneously. This significantly hinders robots from executing accurate, time‐sensitive interaction tasks, particularly during dynamic slight‐contact events. Here, a 130 μm‐thick flexible tactile sensor array is designed, with spatial resolution enhanced by a tailored deep learning model, multistage attention‐based adaptive spatial–temporal graph convolutional networks (MS‐AASTGCN), simultaneously achieving a dynamic response of ≈30 ms and a super‐resolution factor of 75.19. The tactile sensor array, based on single‐electrode triboelectric nanogenerators, can detect dynamic subtle stimuli. It features a bio‐inspired topological structure, facilitating super‐resolution performance while offering a large perception area with low sensor (taxel) density. Additionally, the MS‐AASTGCN enhances positioning resolution by extracting features fromsensing data and revealing the hidden relationships among taxels. This research provides new insights into haptic perception systems, enabling the execution of precise, time‐sensitive interaction tasks, such as tracking a bouncing table tennis ball.","url":"https://doi.org/10.1002/aisy.202400913","authors":["Shuyao Zhou","Depeng Kong","Mengke Wang","Baocheng Wang","Yuyao Lu","Honghao Lyu","Zhangli Lu","Yong Tao","Kaichen Xu","Geng Yang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-02T19:15:36Z","doi":"10.1002/aisy.202400913","addedAt":"2026-08-31T06:34:50.037Z","updatedAt":"2026-08-31T06:34:50.037Z"},{"id":"doi:10.1109/sii59315.2025.10871020","name":"Low-Cost Robot Operation Interface for Simultaneous Hand Position Input and Force Fine-Tuning Using Visual-Based Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/sii59315.2025.10871020","authors":["Tomoya Morita","Yuki Yamashita","Yaonan Zhu","Yasuhisa Hasegawa"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-02-12T18:17:07Z","doi":"10.1109/sii59315.2025.10871020","addedAt":"2026-08-31T06:34:50.037Z","updatedAt":"2026-08-31T06:34:50.037Z"},{"id":"doi:10.1109/cei66465.2025.11398618","name":"Microstructure Design, Encapsulation, and Performance Study of a Dual-Mode Flexible Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/cei66465.2025.11398618","authors":["Zeyu Meng","Sihan Zhang","Yang Zuo","Wenhua Gu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-02-26T20:42:23Z","doi":"10.1109/cei66465.2025.11398618","addedAt":"2026-08-31T06:34:50.037Z","updatedAt":"2026-08-31T06:34:50.037Z"},{"id":"doi:10.1017/s0263574725101768","name":"A morphologically adaptive dome-shaped tactile sensor for evaluating elastic modulus and defect depth","source":"crossref","abstract":"Abstract This article introduces a dome-type soft tactile sensor that can autonomously adjust its stiffness to evaluate surface contact characteristics, including the elastic modulus, contact force, and the presence of abnormal hardness within soft materials, using a strain gauge as a single sensing element. The strain sensor element is placed at the tip of the dome to measure the deformations during contact that reflect the properties of the contacted object. Using machine learning techniques, the sensor system can accurately predict these characteristics in various materials with an error rate of less than approximately 8%. A hybrid approach that combines experimental and simulation data enables the sensor to be trained effectively, generating sufficient data for accurate predictions without extensive experiments.

In nature, weakly electric fish offer a compelling solution through active electrolocation, an evolved electrosensory system that enables them to both localize and identify objects by sensing perturbations in a self-generated electric field. While this strategy is well-documented in liquids, its application in solid-state tactile sensing has remained a challenge. Inspired by this mechanism, we propose a bio-inspired tactile sensor that replicates the electric fish’s discharge and reception functions using paired emitting electrodes and an array of receiving electrodes embedded in conductive rubber. This design enables contact point positioning and material resolution functions to be achieved on a unified sensor through the principle of shared electric fields. Using a voltage-pattern-based algorithm and a multilayer neural network, we achieved an average localization accuracy of 84.2% (with performance improving to 89.1% under standardized pressure conditions) and a material classification accuracy of 88.3% across five distinct materials. Our analysis also confirms the sensor’s robust performance across a range of excitation amplitudes and frequencies. This work demonstrates the feasibility of translating electrolocation principles from aquatic biology into solid-state tactile sensing systems. The resulting compact and versatile interface offers a promising solution for robotic exploration, prosthetics, and human-machine interaction.","url":"https://doi.org/10.1088/2631-8695/ae2189","authors":["Cong Yang","Jiegang Peng"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-11-19T22:55:09Z","doi":"10.1088/2631-8695/ae2189","addedAt":"2026-08-31T06:34:50.037Z","updatedAt":"2026-08-31T06:34:50.037Z"},{"id":"doi:10.1109/iros60139.2025.11247580","name":"A Lightweight 3-axis Permanent Magnetic Sponge-based Self-Adapting Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iros60139.2025.11247580","authors":["Yushi Wang","Devesh Abhyankar","Yuhiro Iwamoto","Zhengxue Cheng","Ruotong Zhao","Shigeki Sugano","Mitsuhiro Kamezaki"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-11-27T18:54:45Z","doi":"10.1109/iros60139.2025.11247580","addedAt":"2026-08-31T06:34:50.037Z","updatedAt":"2026-08-31T06:34:50.037Z"},{"id":"doi:10.1002/eej.23525","name":"Novel Estimation Method of Force Application Point for Cantilever‐Type MEMS Tactile Sensor","source":"crossref","abstract":"ABSTRACT In this paper, we propose a new evaluation method for the spatial distribution of sensitivity to force in a cantilever‐type MEMS tactile sensor developed in our laboratory.

The research focuses on evaluating the quality of experience (QoE) of users interacting with a teleoperation system comprising a local robotic arm, a robot gripper, and heterogeneous remote tracking and haptic feedback devices. By employing a modular device-agnostic framework, the system supports flexible configurations, including one-user-one-equipment (1U-1E), one-user-multiple-equipment (1U-ME), and multiple-users-multiple-equipment (MU-ME) scenarios. The experimental set-up involves participants manipulating predefined objects and placing them into designated baskets by following specified 3D trajectories. Performance is measured using objective QoE metrics, including temporal efficiency (time required to complete the task) and spatial accuracy (trajectory similarity to the predefined path). In addition, subjective QoE metrics are assessed through detailed surveys, capturing user perceptions of presence, engagement, control, sensory integration, and cognitive load. To ensure flexibility and scalability, the system integrates various haptic configurations, including (1) a Touch kinaesthetic device for precision tracking and grounded haptic feedback, (2) a DualSense tactile joystick as both a tracker and mobile haptic device, (3) a bHaptics DK2 vibrotactile glove with a camera tracker, and (4) a SenseGlove Nova force-feedback glove with VIVE trackers. The modular approach enables comparative analysis of how different device configurations influence user performance and experience. The results indicate that the objective QoE metrics varied significantly across device configurations, with the Touch and SenseGlove Nova set-ups providing the highest trajectory similarity and temporal efficiency. Subjective assessments revealed a strong correlation between presence and sensory integration, with users reporting higher engagement and control in scenarios utilizing force feedback mechanisms. Cognitive load varied across the set-ups, with more complex configurations (e.g., 1U-ME) requiring longer adaptation periods.

Initially, a PZT layer was deposited through four successive spin-coating cycles, followed by an additional layer formed via RF sputtering. The resulting multilayer structure was annealed at 700 &#xb0;C for 2 h to improve crystallinity. Comprehensive material characterization was conducted using XRD, SEM, cross-sectional SEM, EDX, and UV-VIS absorbance spectroscopy. The analyses confirmed the formation of a well-crystallized perovskite phase, a uniform surface morphology, and an optical band gap of approximately 3.55 eV, supporting its suitability for sensing applications. Building upon these findings, a multilayer PZT-based touch sensor was fabricated and electrically characterized. Low-frequency I-V measurements demonstrated consistent and repeatable polarization behavior under cyclic loading conditions. In addition, |Z|-f measurements were performed to assess the sensor's dynamic electrical behavior. Although expected dielectric responses were observed, the absence of distinct anti-resonance peaks suggested non-idealities linked to Ag+ ion diffusion from the electrode layers. To account for these effects, the classical Butterworth-Van Dyke (BVD) equivalent circuit model was extended with additional inductive and resistive components representing parasitic pathways. This modified model provided excellent agreement with the measured impedance and phase data, offering deeper insight into the interplay between material degradation and electrical performance.

Here, we present a vision-based contact force estimator that serves as a more cost-effective and easier-to-implement alternative to existing force sensors by leveraging deformations of compliant hands upon contacts when compliant hands are in use. Our approach uses an estimator that visually observes a specialized compliant robot hand (available open source with easy fabrication through 3D printing) and predicts the contact force on the basis of its elastic deformation upon external forces. Because using wrist-mounted cameras to observe the gripper is common for robot manipulation systems, our method can obtain additional force information provided that the gripper is compliant. We optimized our compliant hand to minimize friction and avoid singularities in finger configurations, and we introduced memory to the estimator to combat the partial observability of the contact forces from the remaining friction and hysteresis. In addition, the estimator was made robust to background distractions and finger occlusions using vision foundation models to segment out the fingers. Although it is less accurate and slower than commercial force/torque sensors, we experimentally demonstrated the accuracy and robustness of our estimator (achieving between 0.2 newton and 0.4 newton error) and its utility during a variety of manipulation tasks using the gripper in the presence of noisy backgrounds and occlusions.","url":"https://pubmed.ncbi.nlm.nih.gov/40561044/","authors":["Zhu Y","Hao M","Zhu X","Bateux Q","Wong A","Dollar AM"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2025 Jun 25","doi":"10.1126/scirobotics.adq5046","addedAt":"2026-08-31T06:34:50.038Z","updatedAt":"2026-08-31T06:34:50.038Z"},{"id":"pmid:40544493","name":"Bionic Perception of Surface Adhesion via a Magnetized Spring-like Sensor with Axial Stretchability.","source":"pubmed","abstract":"Perception of surface adhesion is one essential capability of a human fingertip, which is normally realized by touching the target surface with subsequent skin vibrations. However, such functionality is difficult to realize in flexible sensors and robotic systems due to the challenges in axial stretchability with reliable electrical feedback. In this study, we developed a bionic three-dimensional flexible magnetized spring (3D-FMS) that can quantitatively recognize surface adhesion based on electromagnetic induction. Combined with the laser processing with predefined patterns, we show that a raw flexible cube can be converted to highly stretchable spring-like geometry with excellent bidirectional deformation in axial orientation. Furthermore, the mechanical elongation caused by adhesion is critical for the induced voltage signals, allowing us to establish a model that relates adhesion strength with electrical outputs in a linear behavior.

However, previous studies have reported challenges in enhancing the device's sensitivity and determining the direction of external forces. Inspired by the whisker of a rodent, a high-sensitivity whisker sensor (HSWS) is reported with a sensitivity of 62.6 kPa -1 . This exceptional sensitivity is attributed to the design of a torque amplification structure, which transforms a external tiny mechanical stimulus into substantial material deformation in the sensitive layer. This deformation enhances the resistance changeable rate of the varistor, thereby improving the sensor's responsiveness to external stimuli and enabling precise calculation of the magnitude and direction of external forces. The whisker sensor exhibits excellent durability and stability after 5000 testing cycles. In addition, it can sense other environmental parameters such as wind speed and material surface texture. Finally, the whisker sensor is assembled into a bionic electronic mouse capable of distinguishing the traveling direction and distance to walls, assisting in autonomous navigation tasks within a maze.

We evaluated the geometric and mechanical properties of cricket antennae, which we treat as bending cantilever beams. Flexural rigidity (EI) is the mechanical property that most significantly controls bending behavior. We determined that the flexural rigidity decreases steeply (proximal to distal) by evaluating the quasistatic bent shapes in response to obstacle contact at different points along the antennae. This steep decrease in flexural rigidity causes the antennae to bend readily only near the obstacle contact, in contrast to the curvature of a beam with uniform properties and cross-section (which bends closer to the base). This flexural rigidity gradient in the antennae is consistent with the morphology: a decreasing second moment of area calculated from the measured taper and the diminishing wall (cuticle) thickness. Cricket antennae recovered from a single localized perturbation quickly and with minimal to no oscillation, suggesting behavior close to critical damping (fastest return without oscillations). Bending primarily occurred in the portion of the flagellum near the obstacle contact, reducing the length of the flagellum that participated in the oscillating behavior (natural frequency &#x223c;11&#x2005;Hz). Forced sinusoidal vibrations generated a resonance frequency of &#x223c;30&#x2005;Hz with imperceptible movement in the proximal part of the flagellum while the distal part vibrated.

However, the curbs themselves are also significant navigation hazards, particularly for people who are blind or have low vision (pBLV). The challenges faced by pBLV in detecting and properly orienting themselves for these abrupt elevation changes can lead to falls and serious injuries. Despite recent advancements in assistive technologies, the detection and early warning of curbs remains a largely unsolved challenge. This paper aims to tackle this gap by introducing a novel, multi-faceted sensory substitution approach hosted on a smart wearable; the platform leverages an RGB camera and an embedded system to capture and segment curbs in real time and provide early warning and orientation information. The system utilizes a YOLOv8 segmentation model which has been trained on our custom curb dataset to interpret camera input. The system output consists of adaptive auditory beeps, abstract sonifications, and speech, which convey curb distance and orientation. Through human-subjects experimentation, we demonstrate the effectiveness of the system as compared to the white cane. Results show that our system can provide advanced warning through a larger safety window than the cane, while offering nearly identical curb orientation information.

Among different piezoelectrically active polymers, poly(vinylidene fluoride) and its copolymers have attracted considerable attention for energy conversion due to their high flexibility, thermal stability, and biocompatibility. However, the orientation of polymer chains for self-poling under mild conditions is still a challenging task. Herein, anisotropic poly(vinylidene fluoride- co -trifluoroethylene) (PVDF-TrFE)/MXene aerogel-based piezoelectric generators with highly oriented MXene fillers are fabricated. The unidirectional freezing of a hybrid solution facilitates the strain-induced alignment of MXene nanosheets and polymer chains along the solvent crystal growth direction due to the robust interactions between the MXene nanosheets (O-H/F groups) and PVDF-TrFE chains (F-C/C-H groups). Consequently, this process fosters the development of abundant electroactive &#x3b2; crystals with preferred alignment characteristics, leading to the formation of intrinsic self-oriented dipoles within the PVDF-TrFE aerogel. As a result, the piezoelectric properties of PVDF-TrFE are fully harnessed without any complex poling process, resulting in an open-circuit voltage of around 40 V with MXene loading of 3 wt % in anisotropic aerogel, which is 2-fold higher than that of the corresponding isotropic aerogel where the MXene nanosheets and polymer chains are randomly aligned. Furthermore, the developed piezoelectric nanogenerator was demonstrated as a tactile sensor which showed a high sensitivity of 9.6 V/N for lower forces (less than 2 N) and a sensitivity of 1.3 V/N in the higher force regime (2 N &lt; force &lt; 10 N).

The most significant enhancement is that the aligned electrospun core-shell P(VDF-TrFE) nanofibers exhibited almost 40 times higher sensitivity than that of pressure sensor based on thin-film PVDF.","url":"https://pubmed.ncbi.nlm.nih.gov/29364175/","authors":["Wang X","Sun F","Yin G","Wang Y","Liu B","Dong M"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2018 Jan 24","doi":"10.3390/s18020330","addedAt":"2026-08-31T06:34:50.040Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1021/acsaelm.6c00290.s001","name":"Machine-Learning-Assisted Fingerprint-Inspired Triboelectric Tactile Sensor for High-Performance Material and Texture Discrimination","source":"crossref","abstract":"","url":"https://doi.org/10.1021/acsaelm.6c00290.s001","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-24T15:10:41Z","doi":"10.1021/acsaelm.6c00290.s001","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1109/transducers61432.2025.11110965","name":"Simultaneous Acquisition of Viscous and Elastic Proparties by Single Measurement Scan of Fingertip-Type Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/transducers61432.2025.11110965","authors":["Aoi Itou","Adila Safiah Binti Azhar","Kyohei Terao","Hidekuni Takao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-08-19T18:06:19Z","doi":"10.1109/transducers61432.2025.11110965","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1007/978-3-032-01486-3_6","name":"Marker Density of Optical Tactile Sensor for Moving Object Tracking","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-032-01486-3_6","authors":["Bhoomika Gandhi","Sanja Dogramadzi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-08-19T15:47:13Z","doi":"10.1007/978-3-032-01486-3_6","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.2139/ssrn.5247594","name":"A Flexible Microfiber Tactile Wearable Sensor Inspired by the Microstructure of Fingertip Skin for Human Pulse Monitoring","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.5247594","authors":["Yongfeng Zou","Miao Liu","Jingru Mao","Yuejiang Yu","Hanlin Liu","Shuyuan Guo","Dandan Sun","Jie Ma"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-13T19:05:41Z","doi":"10.2139/ssrn.5247594","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1016/b978-0-44-321913-9.00002-3","name":"Front Matter","source":"crossref","abstract":"","url":"https://doi.org/10.1016/b978-0-44-321913-9.00002-3","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-07-23T09:07:15Z","doi":"10.1016/b978-0-44-321913-9.00002-3","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1109/lsens.2025.3531939","name":"Tweelie: Tactile Wheel-Shaped Sensor for Force Reconstruction and Localization Over Curved Spherical Surface","source":"crossref","abstract":"","url":"https://doi.org/10.1109/lsens.2025.3531939","authors":["Thijs Van Hauwermeiren","Anatolii Sianov","Annelies Coene","Guillaume Crevecoeur"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-01-20T19:07:08Z","doi":"10.1109/lsens.2025.3531939","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1109/aim64088.2025.11175763","name":"Design of soft gripper with attached tactile sensor for underwater object grasping and force detection","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim64088.2025.11175763","authors":["Zhongtan Zhang","Xiyi Jiang","Deqing Mei","Yancheng Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-09-29T17:51:31Z","doi":"10.1109/aim64088.2025.11175763","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1002/adrr.202500117","name":"<i>TacScope</i>: A Miniaturized Vision‐Based Tactile Sensor for Surgical Applications","source":"crossref","abstract":"The lack of tactile feedback in robot‐assisted minimally invasive surgery (RMIS) limits surgeons’ ability to palpate tissues, a critical technique for locating abnormalities such as tumors.

An essential role of a tactile sensor is to detect both normal and shear forces, which are generated by various external stimuli. Currently, many researchers use normal and shear force sensors to gather precise data on grasping force and detect slippage. However, most existing flexible tactile sensors sacrifice the sensing performance of the normal component—such as linearity, sensitivity, and pressure sensing range—when attempting to detect both normal and shear forces. This is because incorporating additional mechanisms for shear force detection often degrades the normal force sensing. 1-4 This poses a critical challenge, as the degradation of normal force sensing can reduce overall accuracy and often necessitates additional calibration or computational compensation to reliably interpret both force components. Previous studies have typically used microstructures with multi-contact mechanisms to measure shear forces. In this method, normal forces are measured at multiple locations, and shear forces are calculated from the differences between them. However, these approaches still degrade the performance of normal force sensing and increase system complexity. Therefore, a more effective microstructure design is needed to directly and reliably detect shear forces without compromising normal sensing performance. In this work, we present a flexible tactile sensor able to detect shear forces without sacrificing performance in the normal direction. Our sensor is a piezoresistive sensor that combines the new asymmetric structure mechanism 4 with the widely used multi-contact mechanism 1,2,3 for measuring shear force. We initiate our study by a systematically designed deltoid shaped microstructure that should be able to provide broad-range linearity according to our finite element analysis (FEA). The desired sensing performance is accomplished by designing each pillar to be exponentially wider at the bottom than at the top. The microstructure was subsequently fabricated via 3D printing using a flexible elastomer in a multi-contact arrangement. A conductive poly(3,4-ethylenedioxythiophene) (PEDOT) coating was applied using oxidative chemical vapor deposition (oCVD), uniquely enabling conformal coating of the conductive polymer as the sensing element onto the 3D printed microstructure 5,6 . When shear forces are measured using an optimized asymmetric microstructure, the sensing performance varies depending on the orientation of the structure. Among the tested geometries, the deltoid-shaped rhombic array exhibited the highest shear force sensitivity and a broad pressure sensing range. Furthermore, by arranging the fabricated sensors in a multi-unit array, we established a tactile sensing platform capable of simultaneously detecting pressures of varying magnitudes and directions. A comparison with control devices also confirmed that the performance of normal force sensing was not compromised. Our finding highlights the shear force detection sensor as an attractive solution for robotic manipulators and prosthetics, while also positioning it as a promising foundation for future innovations in this ever-evolving field.

of A Flexible Liquid Metal Tactile Sensor Based on Finite Element Analysis for Pressure and Motion Detection","source":"crossref","abstract":"Abstract Liquid metals (LMs) have emerged as prominent materials for flexible pressure sensing owing to their exceptional conductivity and fluidity. Typically, external loads induce changes in the shape and volume of conductive LM pathways to achieve pressure detection. To optimize sensor's pressure sensitivity, theoretical modeling and finite element simulations are employed to investigate the effects of microchannel thickness and patterns. Results revealed that symmetrical patterns and thinner microchannels significantly enhanced sensor's pressure sensitivity. Furthermore, a novel polyvinyl alcohol (PVA) sacrificial template method is proposed that enables the flexible fabrication of microchannels with various shapes and thicknesses, achieving a minimum channel thickness of 25 µm. The LM sensor demonstrates excellent performance metrics, including a maximum sensitivity of 0.01212 kPa −1 , a wide detection range from 0 to 60 kPa, and remarkable cyclic stability up to 3000 cycles. In practical applications, the sensor enables high‐precision monitoring of various human movements, whereas sensor arrays can effectively detect force distributions across different objects. This paper presents a straightforward and efficient approach for regulating and designing conductive microchannel paths. Additionally, the integration of finite element simulations facilitates optimal sensor pattern design, and the fabricated sensors show tremendous potential for applications in pressure recognition and motion detection.","url":"https://doi.org/10.1002/aelm.202500124","authors":["Zhou Zhao","Xiaoyang Zou","Jing Zhang","King Wai Chiu Lai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-05-23T00:40:33Z","doi":"10.1002/aelm.202500124","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1299/jsmermd.2025.1a2-s08","name":"Wide dynamic range enhancement of a marker displacement based tactile image sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmermd.2025.1a2-s08","authors":["Rintaro YASUTAKE","Kazuhiro SHIMONOMURA"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-12-24T22:08:46Z","doi":"10.1299/jsmermd.2025.1a2-s08","addedAt":"2026-08-31T06:34:50.592Z","updatedAt":"2026-08-31T06:34:50.592Z"},{"id":"doi:10.1117/12.3051340","name":"Robust, low-cost, and stretchable matrix tactile sensor array with anti-ghosting capabilities","source":"crossref","abstract":"","url":"https://doi.org/10.1117/12.3051340","authors":["Junhao Ni","Andreas Richter","Gerald Gerlach","E.-F.

The proposed sensor can measure the normal and shear forces with high sensitivity and linear response. The capacitive tactile sensor is fabricated by low-cost rapid prototyping techniques using conductive ink for electrode printing that is printed on a polyethylene terephthalate sheet by an inkjet printer. Ecoflex 00-30 and silicone rubber RTV-528 are used as the dielectric medium and dome for force application. A finite element method analysis is performed for deciding the dimensions of the sensor's stationary electrodes. The force measurement ranges of the sensor for the normal and shear axis are 4 N and 2 N, respectively.

The sensing performance of tactile sensors is commonly affected by external deformations like stretching, bending, and twisting, thus they may fail to function on deformable object surfaces. This paper presents a stretchable tactile sensor array using kirigami‐patterned structural design and soft hinges to reduce the influences of deformation. The kirigami pattern of sensor array is parametrically studied to achieve the required expansion patterns. Laser engraving is employed to modify the micropillars on the force‐sensitive rubber surface to increase the sensitivity. Characterization tests show that the sensor array has high sensitivity (≈1.49 × 10 −1 kPa −1 ) for force sensing, and the stretching and bending deformation have almost negligible effects on sensing performance. Under 40% stretching or 180° bending conditions, the measured resistance changes (Δ R / R 0 ) is ≈0.03 and 0.06, respectively. To demonstrate the capability of developed sensor array, it is mounted on an expandable balloon surface for force detection. The recorded signals changed less than 1.5% during expanding process while rapidly rose under applied force, which indicated that the sensor array has the potential to effectively function on complex and deforming surfaces.","url":"https://doi.org/10.1002/adsr.202400012","authors":["Chenhao Mao","Jie Jin","Deqing Mei","Yancheng Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-03T23:20:11Z","doi":"10.1002/adsr.202400012","addedAt":"2026-08-31T06:34:51.326Z","updatedAt":"2026-08-31T06:34:51.326Z"},{"id":"doi:10.1016/j.sna.2024.115761","name":"Multiphysics simulation and design framework for developing a vision-based tactile sensor with force estimation and slip detection capabilities","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.sna.2024.115761","authors":["Mohammad Amin Mirzaee","Ali Sadighi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-08T06:08:11Z","doi":"10.1016/j.sna.2024.115761","addedAt":"2026-08-31T06:34:51.326Z","updatedAt":"2026-08-31T06:34:51.326Z"},{"id":"doi:10.1016/j.sna.2024.115728","name":"ZnO-based triboelectric nanogenerator and tribotronic transistor for tactile switch and displacement sensor applications","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.sna.2024.115728","authors":["P.

The article presents an approach for the integration of a micro-electromechanical system sensing skin with 144 tactile sensors on a soft, human-sized artificial fingertip. The sensing technology consists of thin, 1D sensing strips which are wrapped around the soft and curved fingertip. The sensing strips include 0.5&#x2009;mm diameter capacitive sensors which measure touch, vibrations, and strain at a resolution of 1 sensor/mm 2 . The method allows to leverage the advantages of sensing skins over other tactile sensing technologies while showing a solution to integrate such skins on a soft three-dimensional body. The adaptable sensing characteristics are dominated by the thickness of a spray coated silicone layer, encapsulating the sensors in a sturdy material. We characterized the static and dynamic sensing capabilities of the encapsulated taxels up to skin thicknesses of 600&#x2009;&#x3bc;m. Taxels with 600&#x2009;&#x3bc;m skin layers have a sensitivity of 6 fF/mN, corresponding to an &#x223c;5 times higher sensitivity than a human finger if combined with the developed electronics. They can detect vibrations in the full tested range of 0-600&#x2009;Hz. The softness of a human finger was measured to build an artificial sensing finger of similar conformity. Miniaturized readout electronics allow the readout of the full finger with 220&#x2009;Hz, which enables the observation of touch and slipping events on the artificial finger, as well as the estimation of the contact force. Slipping events can be observed as vibrations registered by single sensors, whereas the contact force can be extracted by averaging sensor array readouts.

Our new biohybrid model couples an artificial hand with biological neural networks (BNN) cultured in a multichannel microelectrode array (MEA). We decoded neural activity to control a finger of the artificial hand that was outfitted with a tactile sensor. The fingertip sensations were encoded into rapidly adapting (RA) or slowly adapting (SA) mechanoreceptor firing patterns that were used to electrically stimulate the BNN. We classified the coherence between afferent and efferent electrodes in the MEA with a convolutional neural network (CNN) using a transfer learning approach. The BNN exhibited the capacity for functional specialization with the RA and SA patterns, represented by significantly different robotic behavior of the biohybrid hand with respect to the tactile encoding method. Furthermore, the CNN was able to distinguish between RA and SA encoding methods with 97.84% &#xb1; 0.65% accuracy when the BNN was provided tactile feedback, averaged across three days in vitro (DIV). This novel biohybrid research platform demonstrates that BNNs are sensitive to tactile encoding methods and can integrate robotic tactile sensations with the motor control of an artificial hand.

Still, there are challenges for texture classification regarding the vast amount of time series data generated from robots' sensors. For instance, robots are anticipated to leverage human feedback during interactions with the environment, particularly in cases of misclassification or uncertainty. With the diversity of objects and textures in daily activities, Active Learning (AL) can be employed to minimize the number of samples the robot needs to request from humans, streamlining the learning process. In the present work, we use AL to select the most informative samples for annotation, thus reducing the human labeling effort required to achieve high performance for classifying textures. We also use a sliding window strategy for extracting features from the sensor's time series used in our experiments. Our multi-class dataset (e.g., 12 textures) challenges traditional AL strategies since standard techniques cannot control the number of instances per class selected to be labeled. Therefore, we propose a novel class-balancing instance selection algorithm that we integrate with standard AL strategies. Moreover, we evaluate the effect of sliding windows of two-time intervals (3 and 6 s) on our AL Strategies. Finally, we analyze in our experiments the performance of AL strategies, with and without the balancing algorithm, regarding f1-score, and positive effects are observed in terms of performance when using our proposed data pipeline. Our results show that the training data can be reduced to 70% using an AL strategy regardless of the machine learning model and reach, and in many cases, surpass a baseline performance.

In mice lacking caldendrin ( Cabp1 KO), heightened responses to tactile stimuli correlate with enlarged MA currents with lower mechanical thresholds in dorsal root ganglion neurons (DRGNs). The expression pattern of caldendrin in the DRG parallels that of the major MA channel required for touch sensation, PIEZO2.

Also, haptic sensors were developed to allow transmission of sensation from robotic finger to surgeon's finger. A complete system of a, 3D printed by a stereolithography (SLA) 3D printer, robotic surgical finger with haptic feedback system is proposed. The developed system includes a master glove that controls the motion of a 3DOF robotic slave finger while getting haptic feedback of force/pressure exerted on it. The precise control of the slave robotic finger was achieved by applying a Proportional Integral and Derivative (PID), fast and robust, control algorithm using an Arduino based hardware and software module. The individual joint angles, metacarpophalangeal joint (MCP) and proximal interphalangeal joint (PIP), and wrist were measured using rotatory and inertial sensors respectively. The degree of movement for MCP, PIP, and Wrist joints were measured to be 0-86&#xb0;, 0-71&#xb0;, and 0-89&#xb0; respectively. Motion to the robotic finger is mimicked by a glove motion requiring minimal learning curve for the device. The collected data for the slave motion is in good agreement with the master-glove motion data. The vibro-tactile haptic feedback system was developed to distinguish between three different materials to mimic human flesh, tumor, and bone.

The pyro- and piezoelectric properties of the surface-grafted polyelectrolyte brushes are found to sensitively depend on and can be tuned by variation of the counterion. The observed piezo- and pyroelectric properties reflect the structural complexity of polymer brushes, and are attributed to a complex interplay of the non-uniform segment density within these films, together with a non-uniform distribution of counterions and specific ion effects. The fabrication of thin pyroelectric films by surface-initiated polymerization is an important addition to the existing strategies toward such materials. Surface-initiated polymerization, in particular, allows for facile grafting of polar thin polymer films from a wide range of substrates via a straightforward two-step protocol that obviates the need for multistep laborious synthetic procedures or thin film deposition protocols.

Visualized bright green-emitting ML and thermally stimulated luminescence (TSL) directly and rapidly responded to mechano/thermal dual stimulation in the Sr 2 MgAl 22 O 36 :Mn 2+ /PDMS composite film. It is worth mentioning that this study proposed a new idea of direct temperature sensing by the initial intensity of TSL due to thermal-photo energy conversion, unlike previous temperature sensor technology. Based on this, we designed a flexible optical skin with a simple structure and verified its application prospect as a tactile sensing material with dual mechano/thermal response, establishing a unique imaging mode and providing a convenient, reliable, and sensitive way to remotely visualize the distribution of stress and temperature. This study paves a new way for the development of optical skins with simple structures and sensitive visibility in the application of intelligent robot tactile sensing.","url":"https://pubmed.ncbi.nlm.nih.gov/36689634/","authors":["Li N","Yu S","Zhao L","Zhang P","Wang Z","Wei Z","Chen W","Xu X"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2023 Feb 6","doi":"10.1021/acs.inorgchem.2c03540","addedAt":"2026-08-31T06:34:51.327Z","updatedAt":"2026-08-31T06:34:51.327Z"},{"id":"pmid:36327180","name":"Tactile Transfer Learning and Object Recognition With a Multifingered Hand Using Morphology Specific Convolutional Neural Networks.","source":"pubmed","abstract":"Multifingered robot hands can be extremely effective in physically exploring and recognizing objects, especially if they are extensively covered with distributed tactile sensors. Convolutional neural networks (CNNs) have been proven successful in processing high dimensional data, such as camera images, and are, therefore, very well suited to analyze distributed tactile information as well. However, a major challenge is to organize tactile inputs coming from different locations on the hand in a coherent structure that could leverage the computational properties of the CNN. Therefore, we introduce a morphology-specific CNN (MS-CNN), in which hierarchical convolutional layers are formed following the physical configuration of the tactile sensors on the robot. We equipped a four-fingered Allegro robot hand with several uSkin tactile sensors; overall, the hand is covered with 240 sensitive elements, each one measuring three-axis contact force. The MS-CNN layers process the tactile data hierarchically: at the level of small local clusters first, then each finger, and then the entire hand. We show experimentally that, after training, the robot hand can successfully recognize objects by a single touch, with a recognition rate of over 95%. Interestingly, the learned MS-CNN representation transfers well to novel tasks: by adding a limited amount of data about new objects, the network can recognize nine types of physical properties.","url":"https://pubmed.ncbi.nlm.nih.gov/36327180/","authors":["Funabashi S","Yan G","Hongyi F","Schmitz A","Jamone L","Ogata T","Sugano S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2024 Jun","doi":"10.1109/TNNLS.2022.3215723","addedAt":"2026-08-31T06:34:51.327Z","updatedAt":"2026-08-31T06:34:51.327Z"},{"id":"pmid:32002815","name":"Post-exercise Response of Arterial Parameters for Arterial Health Assessment Using a Microfluidic Tactile Sensor and Vibration-Model-Based Analysis: A Proof-of-Concept Study.","source":"pubmed","abstract":"Arterial stiffness and endothelial function are two established surrogate markers of subclinical atherosclerosis and are quantified by three arterial parameters: elasticity, viscosity and radius of the arterial wall.

One particular area where it has significant promise is the traversal of challenging, varied terrain. Depending on whether an environment is slippery, soft, hard or dry, a robot must adapt its method of locomotion accordingly. Currently many multi-legged robots, such as Boston Dynamic's Spot robot, have preset gaits for different surface types, but struggle over terrains where the surface type changes frequently. Being able to automatically detect changes within an environment would allow a robot to autonomously adjust its method of locomotion to better suit conditions, without requiring a human user to manually set the change in surface type. In this paper we report on the first detailed investigation of the properties of a particular bio-inspired tactile sensor, the TacTip, to test its suitability for this kind of automatic detection of surface conditions. We explored different processing techniques and a regression model, using a custom made rig for data collection to determine how a robot could sense directional and general force on the sensor in a variety of conditions. This allowed us to successfully demonstrate how the sensor can be used to distinguish between soft, hard, dry and (wet) slippery surfaces. We further explored a neural model to classify specific surface textures. Pin movement (the movement of optical markers within the sensor) was key to sensing this information, and all models relied on some form of temporal information. Our final trained models could successfully determine the direction the sensor is heading in, the amount of force acting on it, and determine differences in the surface texture such as Lego vs smooth hard surface, or concrete vs smooth hard surface.","url":"https://doi.org/10.48550/arxiv.2310.08192","authors":["Shepherd, Dexter R.","Husbands, Phil","Philippides, Andy","Johnson,

The PDMS bump was used as the force conversion structure and the PDMS spacer was used as the fixed end and contact with the PDMS bump layer. The LIG was used as a triboelectric electrode. When an external force is applied to the PDMS bump, the PDMS bump layer makes contact with the LIG electrode and generates triboelectric voltage. Finally, the proposed tactile sensor integrated with a mechanical gripper for fruit grasping was demonstrated.","url":"https://doi.org/10.35848/1347-4065/ad20b5","authors":["Ching Hsieh","Cheng-Chun Huang","Ching-Yuan Su","Yao-Chuan Tsai"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-01-19T17:39:18Z","doi":"10.35848/1347-4065/ad20b5","addedAt":"2026-08-31T06:34:51.649Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1002/admt.202470016","name":"A Flexible Dual‐Mode Capacitive Sensor for Highly Sensitive Touchless and Tactile Sensing in Human‐Machine Interactions (Adv.

It involves estimating the relative poses between multiple tactile sensors using their intrinsic measurements, crucial for coordinating multiple fingers in a dexterous robotic hand, especially when accurate encoders are unavailable. Unlike conventional multi-sensor calibration methods (like cameras), which rely on overlapping sensing regions and feature point matching, calibrating multiple tactile sensors presents unique challenges because these sensors cannot have overlapping sensing regions, precluding the use of shared key-points visible from different sensors. In this paper, we establish the theoretical basis for the MTSC problem, constructing constraint equations based on motions measured at multiple locations on the same grasped object from different tactile sensors. The key is that all these measurements correspond to a shared rigid body motion. A calibration scheme is proposed accordingly, with theoretical analysis conducted to enhance precision. Results in simulation, with objects of different shapes, confirm the validity of the proposed calibration approach. Furthermore, calibration of the relative pose between two GelSlim vision-based tactile sensors in real experiments demonstrates good agreement with the ground truth. The proposed theory and method not only shed light on explaining the accuracy gap between proprioception and tactile sensing in multi-finger manipulation but also pave the way for tactile-encoder-mixed or encoder-free solutions in dexterous multi-finger coordination.","url":"https://doi.org/10.1177/02783649241302840","authors":["Hexi Yu","Jin Liu","Daolin Ma"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-16T02:59:50Z","doi":"10.1177/02783649241302840","addedAt":"2026-08-31T06:34:51.649Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1016/j.isci.2024.110803","name":"Spatiotemporal motion features resulting from tactile interface layouts influence tactile speed perception","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.isci.2024.110803","authors":["Yusuke Ujitoko","Yuko Takenaka","Koichi Hirota"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-08-30T19:51:29Z","doi":"10.1016/j.isci.2024.110803","addedAt":"2026-08-31T06:34:51.649Z","updatedAt":"2026-08-31T06:34:51.649Z"},{"id":"doi:10.1109/robot.1994.350976","name":"Spatial filtering characteristic of elastic cover for tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1994.350976","authors":["M.

It is believed that humans can promptly discern slip and consequently modify grip forces to prevent complete loss of grasp. This paper analyzes and validates two incipient slip detection methods using force and displacement signals from the PapillArray tactile sensor, detecting slip on some of the sensors’ pillars before gross slip occurs. A major contribution of this paper is the development of a novel algorithm that can detect slip caused by either translational or rotational movement of the object relative to the sensor, where previous algorithms were not designed to work for slip caused by rotation. Slip events were independently verified using external camera tracking and subsequently used to evaluate slip detection algorithms operating solely on the PapillArray force and displacement signals. Several algorithm parameters influencing algorithm performance were explored with the goal of optimizing slip detection accuracy. The new algorithm, which can also detect slip for rotational tests, was successful in recognizing slip occurrences using PapillArray data (precision of 85% and recall of 90%), and in detecting incipient slip before gross slip occurs across a range of velocities of translational and rotational movements.

However, achieving multiple stimulus responses is particularly challenging in terms of structural design and has not been fully addressed. Herein, a novel structural design inspired by combining the characteristics of a strain sensor and e‐textile into a hybrid interface to obtain stretchable multiple stimulus‐responsive tactile sensors (stretching stimulus, pressing stimulus, and bending stimulus) is proposed. The sensitive layer of the sensor is designed as a textile microstructure. The sensor, which has a stable performance with excellent ohm property and durability (&gt;2 years), possesses an extraordinary gauge factor (≈200) and a fast response time (≈2.48 ms) under tensile strain, a high sensitivity (≈2.35 kPa −1 ) in a low‐pressure range (≈9 kPa) under pressure. It has excellent performance for Human Activity Recognition by being attached to human skin. In addition, a Bluetooth device that tracks muscle activity in real‐time and transmits the output signals to a smartphone application is utilized.

Unlike the human finger, although most tactile sensors have high sensitivity to pressure, they cannot detect millimeter-level depth information on the surface of objects precisely. To enhance the ability to detect surface depth information, a piezomagnetic sensor combining inverse magnetostrictive effect and bionic structure is developed in this paper. Design/methodology/approach A magnetostrictive tactile sensor based on Galfenol [(Fe 83 Ga 17 ) 99.4 B 0.6 ] is designed and studied for surface depth measurement. The optimal structure of the sensor is determined by experiment and theory. The test platforms for static and dynamic characteristics are set up. The static and the dynamic sensing performance of the sensor are studied experimentally. Findings The sensor can detect 0–2 mm depth change with a sensitivity of 91.5 mV/mm. A resolution of 50 µm can be achieved in the depth direction. In 50 cycles of loading and unloading tests, the maximum error of the sensor output voltage amplitude is only 2.23%. Originality/value The sensor can measure the depth information of object surface precisely with good repeatability through sliding motion and provide reference for object surface topography detection.","url":"https://doi.org/10.1108/sr-01-2022-0051","authors":["Ling Weng","Zhuolin Li","Xu Luo","Yuanye Zhang","Yang Liu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-05-17T00:06:50Z","doi":"10.1108/sr-01-2022-0051","addedAt":"2026-08-31T06:34:52.120Z","updatedAt":"2026-08-31T06:34:54.477Z"},{"id":"doi:10.1109/jflex.2026.3718853/mm1","name":"Self-Powered Tactile Sensor for Human-Machine Interface Using Flexible Piezoelectric Nanogenerator_supp1-3718853.docx","source":"crossref","abstract":"","url":"https://doi.org/10.1109/jflex.2026.3718853/mm1","authors":["Davinder Kaur"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-03T19:08:24Z","doi":"10.1109/jflex.2026.3718853/mm1","addedAt":"2026-08-31T06:34:52.120Z","updatedAt":"2026-08-31T06:34:52.120Z"},{"id":"doi:10.5194/jsss-9-319-2020","name":"A tactile sensor based on magneto-sensitive elastomer to determine the position of an indentation","source":"crossref","abstract":"Abstract. In this paper, we investigate the capabilities of a tactile sensor based on magneto-sensitive elastomers (MSEs). The main feature of the sensor is the determination of the position of indentation. The principle is based on inductance measurements of multiple planar coils and a soft magneto-sensitive layer. The proposed prototype consists of a linear array of hexagonal coils with overlapping sections. First, the results of the experiments are presented, which include a sampling of a sensor region with indentations of constant depth. Subsequently, we introduce a mathematical model based on the bell-shaped flux density distribution of a planar coil. This model consists of ellipse equations with three parameters and a polynomial fit for each parameter. Finally, solving the system of equations results in the determination of the x coordinate of the indentation.","url":"https://doi.org/10.5194/jsss-9-319-2020","authors":["Simon Gast","Klaus Zimmermann"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-10-08T13:14:16Z","doi":"10.5194/jsss-9-319-2020","addedAt":"2026-08-31T06:34:52.120Z","updatedAt":"2026-08-31T06:34:52.120Z"},{"id":"doi:10.1364/ofs.2023.w4.6","name":"Bioinspired self-powered optical fiber sensor array for tactile perception","source":"crossref","abstract":"Inspired by neural tactile sensing system, we innovatively integrate mechanoluminescence material on the endsurface of optical fiber arrays to design a tactile sensor with the merits of high-resolution, low-pressure threshold and self-powering ability.","url":"https://doi.org/10.1364/ofs.2023.w4.6","authors":["Hongyan Zheng","Puxian Xiong","Jiulin Gan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-02-15T16:38:03Z","doi":"10.1364/ofs.2023.w4.6","addedAt":"2026-08-31T06:34:52.120Z","updatedAt":"2026-08-31T06:34:52.120Z"},{"id":"doi:10.1109/memsys.1995.472575","name":"Optical tactile sensor using surface-emitting laser","source":"crossref","abstract":"","url":"https://doi.org/10.1109/memsys.1995.472575","authors":["E.

To perform intelligent tasks, robots are highly required to perceive their operating environment, and react accordingly. With this regard, tactile sensors offer to extend the scope of intelligence of a robot for performing tasks which require object touching, recognition, and manipulation. This paper presents the design of an inexpensive pneumatic binary-array tactile sensor for such robotic applications. The paper describes some of the techniques implemented for object recognition from binary sensory information.

Existing dual-modal sensors often rely on complex multilayer structures or heavy signal processing for decoupling, increasing fabrication difficulty and computational load. This work presents an ultra-flexible proximity-tactile dual-modal sensor using liquid metal microchannels embedded in a monolithic silicone substrate. Spatially separated microchannels include two lateral crescent-shaped coplanar electrodes for capacitance proximity sensing and a central spiral microchannel for piezoresistive tactile sensing. Distinct sensing mechanisms, a non-overlapping layout, and independent readout circuits enable front-end physical decoupling with low observable interference. Experiments show that the proximity region yields material-dependent maximum detection distances with low hysteresis (±3.18%). The tactile region exhibits a stable piezoresistive response over a nominal contact pressure range of 0-127 kPa with acceptable hysteresis (±6.29%), satisfying general flexible tactile sensing requirements. A simple mode-switching strategy based on capacitance and resistance thresholds reliably discriminates the two modalities without machine learning. When integrated on a robotic end-effector, the sensor enables adaptive grasping of objects with different stiffness and real-time dynamic collision avoidance in human-robot interaction.","url":"https://doi.org/10.2139/ssrn.6899061","authors":["Sitong Lu","Zhengguo Liu","Xiaotian Sun","Shouxu Tang","Jian Jiao"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-08T13:42:52Z","doi":"10.2139/ssrn.6899061","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.4271/930112","name":"Automotive Seating Analysis Using Thin, Flexible Tactile Sensor Arrays","source":"crossref","abstract":"&lt;div class=\"htmlview paragraph\"&gt;The recent development of large area, flexible tactile sensors has made it possible to examine the pressure distribution that results when a passenger comes in contact with a car seat.

Here we first realize fully decoupled sensing of normal stress, strain magnitude, and strain direction within a structurally simplified sandwich-type piezoelectric architecture by integrating an ultrathin microcrack-based piezoresistive film as a shared side electrode for four reinforced piezoelectric units. The intrinsic impedance mismatch between the piezoelectric and piezoresistive channels establishes an impedance-domain decoupling that fundamentally enables their crosstalk-free integration within a single device. Meanwhile, local modulus enhancement introduced by glass fiber fabrics reinforcement concentrates in-plane strain into a low-modulus cross-shaped region, physically isolating the piezoelectric units from strain interference, while strain direction-dependent microcrack evolution in piezoresistive film combined with a four-electrode readout enables vector strain sensing. The multimodal sensor achieves a pressure detection limit of 0.125 kPa, a strain linearity of 0.99 over a tensile strain range of 0–20%, and reliable detection of weak human pulse.

It is difficult to seamlessly attach to the surface of the robot. For this reason, this paper proposes a method to prepare nonarray structure tactile sensor directly on the surface of the robot by spraying process. Design/methodology/approach Based on the principle of gradient potential distribution, the potential fields are constructed in two different directions over the conductive film in time-sharing. The potentials at touching position in the two directions are detected to determine the coordinate of the touching point. The designed tactile sensor based on this principle consists of only three layers. Its bottom layer is designed as a weak conductive film made of graphite coating and used to construct the potential field. It can be sprayed either on PET substrate or directly on robot surface. Findings The radial basis function neural network is used for remodeling the potential distribution, which can effectively solve the problem of nonlinear potential distribution caused by irregular sensor shape, and uneven conductivity at different points of the spraying coating. The simulation and experimental results show that the principle of the proposed tactile sensor used for touching position detection is feasible to be applied to complex surfaces of the robot. Originality/value This paper proposed a nonarray customizable tactile sensor based on the spraying process. The sensor has a simple structure, and only five lead wires are needed to realize the coordinate detection of the touch position.","url":"https://doi.org/10.1108/sr-11-2021-0412","authors":["Deyu Wu","Ding Wang","Daliang Yang","Ye Jinhua","Haibin Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-05-28T01:06:55Z","doi":"10.1108/sr-11-2021-0412","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:54.477Z"},{"id":"doi:10.1109/jsen.2024.3417514/mm1","name":"TacTID: High-performance Visuo-Tactile Sensor-based Terrain Identification for Legged Robots_supp1-3417514.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/jsen.2024.3417514/mm1","authors":["Wenbo Ding"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-06-28T14:47:00Z","doi":"10.1109/jsen.2024.3417514/mm1","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/robio49542.2019.8961786","name":"A novel tactile sensor based on structured light","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robio49542.2019.8961786","authors":["Yuanlong Yu","Hongxiang Xue","Zhenzhen Liang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-01-21T19:49:51Z","doi":"10.1109/robio49542.2019.8961786","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/iecon.2005.1569203","name":"Resistive tactile sensor matrices using inter-electrode sampling","source":"crossref","abstract":"","url":"https://doi.org/10.1109/iecon.2005.1569203","authors":["K.

The sensor has been conceived for application in laparoscopic grasping forceps and can also be integrated into a sensing rod, both 15 mm in outside diameter. This optical sensor allows us to display graphically indurations spread in the tissue. Furthermore, the measured values serve to activate a vibrotactile display unit for tactile feedback onto the surgeon&amp;rsquo;s fingertip. In order to obtain further information about the requirements for an analog tactile display, an actuatorarray with 144 pins on a 4 cm2surface area was built.

A vision-based tactile sensor is introduced which can realize visual measurement of three-dimensional displacement in this paper. The vision-based tactile sensor is mainly composed of an elastomer embedded with marker point array, a transparent acrylic plate, 8 LED lamps and a micro monocular camera. The elastomer deforms when the tactile sensor touches an object, and the micro monocular camera is used to capture the elastomer deformation and transmit it to the computer in the form of image, and then the three-dimensional displacement information is obtained by processing the image. In order to more accurately recover the missing dimensional information in the three-dimensional displacement detection of monocular camera, an improved DFD (Depth from Defocus) method based on finite element theory is proposed in this paper. It is verified by experiments that the improved DFD method proposed in this paper can measure the three-dimensional displacement information more accurately compared with the DFD method. The experimental results show that the three-dimensional displacement measurement method proposed in this paper can provide technical support for the design and development of vision-based tactile sensors.","url":"https://doi.org/10.2139/ssrn.4245288","authors":["ZengHong Ma","Wei Zeng","Xiaoqiang Du","Leiying He","Chuanyu Wu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-10-12T19:52:58Z","doi":"10.2139/ssrn.4245288","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1299/jsmeicam.2015.6.290","name":"Identification and Pose Estimation of a Stick-like Object by a Tactile Sensor System for a Robot Hand","source":"crossref","abstract":"","url":"https://doi.org/10.1299/jsmeicam.2015.6.290","authors":["Koichiro Matsumoto","Kimitoshi Yamazaki"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2017-07-22T22:19:58Z","doi":"10.1299/jsmeicam.2015.6.290","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1364/oft.2014.otu4a.1","name":"Comparison of 2D and 3D measurements of aspheres with a tactile and optical sensor on one measuring instrument","source":"crossref","abstract":"","url":"https://doi.org/10.1364/oft.2014.otu4a.1","authors":["Andreas Beutler"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2014-07-11T10:52:15Z","doi":"10.1364/oft.2014.otu4a.1","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.17958/ksmt.20.5.201810.562","name":"Control of Behavior-based for Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.17958/ksmt.20.5.201810.562","authors":["Jeongick Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-10-29T04:32:24Z","doi":"10.17958/ksmt.20.5.201810.562","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/jsen.2024.3477625/mm1","name":"A Tactile Glove Based on Capacitive Pressure Sensor Array for Object Shape Recognition_supp1-3477625.mp4","source":"crossref","abstract":"","url":"https://doi.org/10.1109/jsen.2024.3477625/mm1","authors":["Liangsong Huang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-10-17T13:47:53Z","doi":"10.1109/jsen.2024.3477625/mm1","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/jsen.2023.3237906","name":"Tactile, Orientation, and Optical Sensor Fusion for Tactile Breast Image Mosaicking","source":"crossref","abstract":"","url":"https://doi.org/10.1109/jsen.2023.3237906","authors":["Rory Hampson","Graeme West","Gordon Dobie"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-01-23T14:37:39Z","doi":"10.1109/jsen.2023.3237906","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1121/1.398375","name":"Tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1121/1.398375","authors":["Jan Capek","Miloslav Nevesely","Milan Lansky"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2005-10-13T19:20:49Z","doi":"10.1121/1.398375","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1109/robot.1997.606756","name":"A tactile sensor system for a three-fingered robot manipulator","source":"crossref","abstract":"","url":"https://doi.org/10.1109/robot.1997.606756","authors":["J.

A deep learning scheme PSPNet based on MobileNet was adopted to postprocess the originally reconstructed images to improve the performance of tactile perception.

Human skin contains excellent tactile sensing elements, mechanoreceptors, which detect their assigned tactile stimuli and transduce them into electrical signals. The transduced signals are transmitted through separated nerve fibers to the central nerve system without complicated signal processing. Inspired by the function and organization of human skin, we present a piezoresistive type tactile sensor capable of discriminating the direction and magnitude of stimulations without further signal processing. Our tactile sensor is based on a flexible core and four sidewall structures of elastomer, where highly sensitive interlocking piezoresistive type sensing elements are embedded. We demonstrate the discriminating normal pressure and shear force simultaneously without interference between the applied forces. The developed sensor can detect down to 128 Pa in normal pressure and 0.08 N in shear force, respectively. The developed sensor can be applied in the prosthetic arms requiring the restoration of tactile sensation to discriminate the feeling of normal and shear force like human skin.","url":"https://doi.org/10.3390/s151025463","authors":["Youngdo Jung","Duck-Gyu Lee","Jonghwa Park","Hyunhyub Ko","Hyuneui Lim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2015-10-02T10:05:52Z","doi":"10.3390/s151025463","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.2139/ssrn.4499986","name":"Enhancing Deafblind Assistance Through a Self-Powered Tactile Sensor-Based Braille Typing System","source":"crossref","abstract":"","url":"https://doi.org/10.2139/ssrn.4499986","authors":["Wenqiu Liu","Yu Wu","Kechen Li","Siyaun Zhou","Qi Wang","Hua Yu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-07-04T13:20:46Z","doi":"10.2139/ssrn.4499986","addedAt":"2026-08-31T06:34:52.121Z","updatedAt":"2026-08-31T06:34:52.121Z"},{"id":"doi:10.1016/0250-6874(88)80009-x","name":"An impedance tomographic tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1016/0250-6874(88)80009-x","authors":["Mark Helsel","Jay N.

Many of these projects have in common the use of state of the art actuation and sensing, and therefore are able to handle difficult locomotion tasks very effectively. This work focuses on another trend of low-cost, quadrupedal robots, that features less precise actuators and sensors, but overcomes their limitations with strong bio-inspired designs to achieve state of the art locomotion. We aim here to further extend the achievements of this approach to handle more complex tasks and that require anticipation, We would like also to verify to which extent a close synergy between clever mechanics, sensorimotor coordination, and Central Pattern Generator models is able to handle these tasks. This thesis presents supporting work that was required to pursue this goal. A software architecture for the development of real-time drivers and low-level control for robotic applications, based on a clear separation of concerns is presented. An implementation of this architecture able to handle the specific requirements for small compliant quadruped robots is proposed. Furthermore, the development and integration of a communication protocol for inter-electronic devices communication on the Oncilla robot is discussed. As leg load is a key quantity in some of the sensory-motor coordination this thesis want to explore, a novel tactile sensing approach for its estimation is proposed, based on an Extended Kalman Filter data fusion of static and dynamic tactile sensor information. Then, to support the design of efficient interactions between the control and the bio-inspired mechanics, accurate dynamic modeling of the Advanced Spring Loaded Pantographic leg, equipping all robots considered here, is presented. We propose two approaches to this modeling with the presentation of their benefits and limitations. Finally, two Central Pattern Generator architectures are proposed, based on biologically inspired foot trajectories. The first is using a well-known method for inter-limb coordination with strong neural coupling, and the second, the Tegotae rule, relies only on limb physical coupling and strong sensory-motor coordination. These two approaches are compared on their capacity to handle dynamic footstep placement and it let to the conclusion that strong sensory-motor coordination is required for this task.","url":"https://doi.org/10.5075/epfl-thesis-7458","authors":["Tuleu, Alexandre"],"tags":["Quadrupedal Robots","Biologically-inspired Robots","Central Pattern Generators","Compliant Joint/Mechanism","Control Architectures and Programming","Force and Tactile Sensing","Sensor Fusion","Optimization and Optimal Control"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2016","doi":"10.5075/epfl-thesis-7458","addedAt":"2026-08-31T06:34:52.122Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.82161/1b08-hg34","name":"MEASURES OF MAXIMAL TACTILE PRESSURES DURING A SUSTAINED GRASP TASK USING A TACTARRAY DEVICE HAVE SATISFACTORY RELIABILITY AND VALIDITY","source":"datacite","abstract":"U.

Sustained grasp is essential for functional tasks in daily life. Sensor-based devices can record pressure or force over time during grasping and therefore offer a more comprehensive approach to quantifying grip strength during sustained contractions. The reliability of grip strength using the TactArray device has not been investigated.Purpose: To investigate the reliability and the concurrent validity of maximal tactile pressures and forces of a sustained grasp task using the TactArray device in healthy people and in people with stroke.Methods: Healthy participants (n=18, mean age: 62.2 ± 9.9 years) and participants with stroke (n=11, mean age: 64.1 ± 9.0 years) performed three trials of sustained maximal grasp over 8 seconds. Both hands were tested in within-day (two sessions, one hour apart) and between-day (two sessions, one week apart) sessions, with vision and without vision. Measures of maximal tactile pressures and forces were measured for the complete grasp duration (8s) and for the plateau phase (5s). Measures of maximal tactile pressures and forces were reported using the highest value among the three repetitions, the mean of two repetitions, and the mean of three repetitions. Reliability was determined using changes in mean, coefficients of variation and intraclass correlation coefficients (ICCs). Pearson correlation coefficients were used to evaluate concurrent validity.Results: In healthy individuals, changes in mean were very good (range:-0.09-3.11%), coefficients of variation acceptable (range:9.85-12.95%) and ICCs were good (range:0.59-0.84) for maximal tactile pressures using highest value among the three repetitions and the mean of three repetitions for the complete grasp duration (8s) and for the plateau phase (5s) in the dominant hand with and without vision for within-day and between-day sessions. In the non-dominant hand, changes in mean were very good to good (range:-1.48-6.22%) and coefficients of variation were good to acceptable (range:8.08-12.82%) and ICCs very good to good (range:0.89-0.92) without vision for within-day and between-day sessions. In people with stroke, changes in mean were good (range:-2.02- -7.18%), coefficients of variation were good to acceptable (range:9.52-14.72%) and ICCs very good (range:0.90-0.97) for maximal tactile pressures using Pres(8s)avg3 in the affected hand with and without vision for within-day sessions and without vision for between-day sessions. In the less affected hand, changes in mean were very good (range:0.00-5.04%), coefficients of variations were acceptable (range:11.73-15.92%) and ICCs were good to very good (range:0.88-0.93) for maximal tactile pressures using Pres(5s)avg3 and Pres(8s)avg3 in between-day session with and without vision. Maximal tactile pressures had moderate to large correlations (r=0.4-0.6) with grip strength in health individuals and people with stroke.Conclusion(s): The TactArray device demonstrates satisfactory reliability for measures of maximal tactile pressures during a sustained grasp for within-day and between-day testing sessions using an average of three trials with or without vision in healthy people and those with stroke. Validity was satisfactory with grip strength in both hands.Implications: The TactArray provides reliable intra-day and inter-day measures of maximal tactile pressures in healthy people a","url":"https://doi.org/10.82161/1b08-hg34","authors":["Urvashy Gopaul","Derek Laver","Leeanne Carey","Thomas A Matyas","Paulette van Vliet","Robin Callister"],"tags":["Neurology: stroke"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.82161/1b08-hg34","addedAt":"2026-08-31T06:34:52.122Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.48550/arxiv.2508.12435","name":"Tactile Gesture Recognition with Built-in Joint Sensors for Industrial Robots","source":"datacite","abstract":"While gesture recognition using vision or robot skins is an active research area in Human-Robot Collaboration (HRC), this paper explores deep learning methods relying solely on a robot's built-in joint sensors, eliminating the need for external sensors.

However, tactile images are sensor- and physics-specific, so effective architectures often require expert intuition and extensive manual iteration. Existing neural architecture search (NAS) pipelines can reduce this burden, but they are often computationally expensive and restricted to hand-designed search spaces, which limits architectural novelty and diversity. We introduce TacEvo, a self-evolving architecture discovery framework that improves network designs from downstream feedback. TacEvo uses an LLM to generate code-level mutations and crossovers, and a MAP-Elites quality-diversity loop that preserves diverse elite architectures while preferentially reusing prompts that consistently yield improvements. Exploration is guided by two behavioural descriptors, Architectural Diversity and Efficiency Ratio, which encourage coverage across structural variations and compute-size trade-offs. On ViTacTip force regression and grating classification, TacEvo achieves high autonomous generation reliability (96.0%/94.5% trainable) and improves best validation fitness over 20 generations by 56.1%/96.1%. In a 20-seed post-search high-fidelity evaluation, TacEvo matches the expert baseline on force prediction and outperforms it on fine-grained grating classification. These results suggest that LLM-driven self-evolving search constitutes a practical paradigm for AI-assisted scientific discovery in specialised robotic sensing.","url":"https://doi.org/10.48550/arxiv.2606.30109","authors":["AbuSadeh, Mohammed","Wei, Lan","Zhang, Dandan"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.30109","addedAt":"2026-08-31T06:34:52.122Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.48550/arxiv.2606.29948","name":"Heterogeneous Tactile Transformer","source":"datacite","abstract":"Tactile sensors are inherently heterogeneous: a model trained on one sensor cannot be directly used on another, which limits learning contact-rich manipulation policies from diverse tactile data at scale.

We present YOTO, a tactile-only pose estimation system that recovers the full 6-DoF object pose from a single pair of simultaneous contacts, without requiring contact history. YOTO represents each tactile contact as a local 3D point cloud and localizes it on the object surface through a coarse-to-fine network. The two localized contacts, together with the calibrated sensor poses, are then fed to a closed-form normal-aware SVD solver that recovers the full 6-DoF object pose in one step. To reduce real-data requirements, the localization network is pretrained on virtual tactile patches sampled from the object model and fine-tuned with a small number of real contacts. We further show that YOTO can operate on object models reconstructed from consumer-grade mobile scans, and quantify the gap relative to CAD-based models. Experiments on four geometrically diverse objects demonstrate accurate tactile contact localization and pose estimation, outperforming vision-based and geometric baselines, especially when visual perception is unreliable.

The Central Hub parts list is the hardware side: a single body-worn core (belt/pocket unit) that re-homes the original HMD compute and drives three peripheral families — the LOWKI-derived Handheld Messenger Device (Tracer/Volco), the body-worn cue devices (arm/leg cuffs, Clasp hands, earbuds, flavour interface), and the Presence Headset added last. Internally it carries four blocks: the Frostline-derived Sovereign Control Module (root of trust + hardware kill), the Real-Time Hub Core (octa-core ARM + RTOS interlock MCU), the six-way Cities Hub WiFi, and power. It's a full BOM with order-of-magnitude prototype costs landing around £1,712 for the full rig (≈£1,593 light-only, no micro-OLED), and it's honest about the three genuinely custom items — the Glacial Port latch, the hardware kill interlock, and the Clasp four-channel render — plus the two blocking prereqs (real HMAC auth and a measured wax-valve de-energise spec) before the Sovereign Module is a real rather than narrative root of trust. The Unified Working Spec is the platform itself, and it opens with the honesty that holds the whole thing together — the buildable suggestive-sensory engine (vibration, bone-conduction audio, peripheral light, kinetic torque, fused with EEG/fNIRS and HR biofeedback) versus the visionary quantum-consciousness frame kept as north-star fiction with every promise re-routed to a buildable analog (§15).

The Central Hub parts list is the hardware side: a single body-worn core (belt/pocket unit) that re-homes the original HMD compute and drives three peripheral families — the LOWKI-derived Handheld Messenger Device (Tracer/Volco), the body-worn cue devices (arm/leg cuffs, Clasp hands, earbuds, flavour interface), and the Presence Headset added last. Internally it carries four blocks: the Frostline-derived Sovereign Control Module (root of trust + hardware kill), the Real-Time Hub Core (octa-core ARM + RTOS interlock MCU), the six-way Cities Hub WiFi, and power. It's a full BOM with order-of-magnitude prototype costs landing around £1,712 for the full rig (≈£1,593 light-only, no micro-OLED), and it's honest about the three genuinely custom items — the Glacial Port latch, the hardware kill interlock, and the Clasp four-channel render — plus the two blocking prereqs (real HMAC auth and a measured wax-valve de-energise spec) before the Sovereign Module is a real rather than narrative root of trust. The Unified Working Spec is the platform itself, and it opens with the honesty that holds the whole thing together — the buildable suggestive-sensory engine (vibration, bone-conduction audio, peripheral light, kinetic torque, fused with EEG/fNIRS and HR biofeedback) versus the visionary quantum-consciousness frame kept as north-star fiction with every promise re-routed to a buildable analog (§15). The governing law is cue strength implies; the brain completes. On top of that sit the modules: the §2 consent & safety spine (default-off, continuous revocable consent, waking-only, trauma-throttle, STOP, Valor's Virtue filter), MindCity and the Cities Hub, scene-packs and date rooms (including Fields and the touchable grass), kinetic motion and the bike, heart-rate nudging with hard-control excluded as unsafe, Examine bios, the consent-first intimate edition, Echoes (Moment Capture + affective replay), Clasp telehaptic hand-holding, the flavour layer, the full date arc, the Poetry Corner, and The Commons — the no-faces social space that applies the implication law to identity itself, now expanded with friends-as-first-class, group chat rooms, mini-games, and The Board (ads/news/blogs with no affect targeting). The later sections close the loop: the engineering specs resolve open tasks 1–10 (the suggestion-to-completion fidelity curve, the continuous-consent state machine, the intent-vector JSON schema, the safety interlock precedence order, latency budgets, Mnemosyne blinded logging, Echo screening zones, the flavour cue format, and the emotion-amp gain curve with trauma override), and §19 reframes Frostline as the substrate rather than a bolt-on — a three-zone thermal architecture (cold compute core / warm never-frozen safety island / body-temp I/O) with the cryo-cooled biosignal front end as the real prize, since cooling the AFE drops the Johnson-Nyquist noise floor and directly sharpens the state reads the whole platform depends on. The consistent throughline across both files is the same discipline you've held all along: imply, don't simulate; put safety in hardware, not config; and keep the visionary layer intact as story while shipping only what's honestly buildable.

They break down the critical differences between \"smart home toys\" and \"security tools,\" focusing on hardware reliability, signal jamming, and the importance of redundancy. From the benefits of wired sensors and hybrid systems like Konnected.io to the nuances of LoRa and professional monitoring for DIYers, this conversation provides a roadmap for anyone looking to secure their property. Whether you're a renter looking for flexibility or a homeowner seeking industrial-grade safety, learn how to bridge the gap between open-source innovation and professional-grade peace of mind. Show Notes In the latest episode, hosts Herman Poppleberry and Corn dive into a fundamental debate that every smart home enthusiast eventually faces: the choice between a custom, DIY security setup and a professionally installed, proprietary system. The discussion was sparked by a listener named Daniel, who has spent the last decade perfecting a Home Assistant-based security system in various rental apartments but is now looking toward the future of homeownership. ### The Renter's Constraint vs. The Homeowner's Freedom Herman and Corn begin by acknowledging the \"renter's dilemma.\" For those living in apartments, DIY systems like Zigbee sensors and Home Assistant are often the only option. Landlords rarely permit the drilling, wiring, and permanent modifications required for professional-grade security. In these environments, the flexibility of battery-powered, adhesive sensors is a necessity. However, as Herman points out, the moment you own the \"dirt and the walls,\" the math changes entirely. The freedom to run copper wires and install permanent infrastructure opens the door to a level of reliability that wireless DIY components struggle to match. ### Hardware: Tools vs. Toys The core of the discussion centers on the hardware layer. While a ten-dollar Zigbee door sensor is a marvel of modern engineering, Herman argues that it is often closer to a \"toy\" than a \"tool\" when compared to professional equipment. Professional systems from brands like Honeywell, DSC, or Ajax are UL-listed, meaning they have undergone rigorous testing for signal jamming, physical tampering, and environmental stress. One of the most significant vulnerabilities of DIY systems is the frequency they inhabit. Most Zigbee and Matter devices operate on the 2.4 GHz band—the same crowded frequency used by Wi-Fi, Bluetooth, and even microwaves. This makes them susceptible to both accidental interference and intentional signal jamming. In contrast, professional systems often use sub-GHz frequencies (like 433 MHz or 868 MHz), which offer superior wall penetration and are far less likely to be disrupted by a neighbor's router or a malicious actor with a signal jammer. ### The Redundancy Gap Reliability isn't just about the signal; it's about what happens when things go wrong. Herman highlights the \"redundancy gap\" between DIY and professional setups. A standard DIY setup relies on the home's internet connection and power grid. If a burglar cuts the fiber line outside the house or the power goes out, many smart home notifications die instantly. Professional panels, however, are designed with a \"worst-case scenario\" mindset. They typically feature large lead-acid backup batteries capable of powering the system and high-decibel sirens for 24 to 48 hours. Furthermore, they often include integrated cellular backup modules that don't rely on the home's Wi-Fi or fiber connection to alert a monitoring station. For Daniel's future home, Herman suggests that while Home Assistant is a brilliant \"brain,\" the \"nervous system\" of the house—the sensors and sirens—should ideally be hardened against these common points of failure. ### The Hybrid Solution: Best of Both Worlds For those who love t","url":"https://doi.org/10.5281/zenodo.19359746","authors":["Rosehill, Daniel","Gemini 3.1 (Flash)","Chatterbox TTS"],"tags":["podcast","ai-generated","my weird prompts","smart-home","security-logistics","networking"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.19359746","addedAt":"2026-08-31T06:34:52.122Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.5281/zenodo.19432267","name":"Why Can't You Remember Being a Baby?","source":"datacite","abstract":"Episode summary: Why do our earliest memories vanish? We explore the phenomenon of infantile amnesia, reconstructing what a typical day feels like for a nine-month-old. From a low-to-the-ground perspective to the \"mouth-first\" way of exploring objects, we dive into the sensory reality of a developing brain. You'll learn why babies consume so much energy, how they use parents as external \"filters\" for the world, and why learning to talk might be the very thing that erases these memories. Show Notes There is a strange blank spot in almost every human biography: the first few years of life. While we know we were awake, moving, and experiencing the world, the narrative record is completely silent. This isn't a failure of storage; it is a fundamental feature of how the human brain builds itself. By examining developmental neuroscience, we can reconstruct the \"day in the life\" of a nine-month-old baby—a creature that is less like a miniature adult and more like a high-bandwidth sensory scientist. **The Low-to-the-Ground Perspective** To understand the world of a nine-month-old, you first have to understand their vantage point. Standing only eight inches tall, the environment is architectural and massive. A simple dining chair transforms into a forest of four wooden towers stretching toward the ceiling. The underside of a coffee table becomes a cavernous ceiling. The floor is not just a surface; it is a vast, tactile continent that changes texture every few feet. The transition from cool, slick kitchen tile to a scratchy living room rug is experienced as a significant environmental border crossing, offering a constant stream of topographic data to the knees and palms. **The Mouth as the Primary Sensor** While adults rely on fingertips to judge texture and temperature, a nine-month-old relies on the mouth. The oral region contains an incredibly high density of nerve endings, and at this stage of development, the somatosensory cortex is most active around the lips and tongue. Consequently, the mouth is the primary tool for \"haptic sampling.\" When a baby picks up a plastic block, their eyes see the color and their hands feel the hardness, but only the mouth can reveal the \"truth\" of the object—the microscopic ridges, the temperature, and the true texture. This isn't necessarily hunger; it is the brain's most effective way of \"reading\" the physical properties of the world. **The 60% Brain Budget** The energy required for this existence is staggering. A nine-month-old's brain consumes approximately 60% of their total metabolic energy, compared to about 20% in an adult. This is because the brain is undergoing synaptogenesis—the creation of up to a million new neural connections every second. It is a construction site operating at full speed. This massive cognitive workload explains the notorious \"crash\" cycles of babies. After 90 minutes of intense sensory input, the brain reaches a buffer overflow. The resulting deep, heavy nap isn't just rest; it is the necessary processing time to integrate that data. When they wake up, they are literally a more complex person than they were before they slept. **External Filters and Emotional Mirrors** A nine-month-old lacks a functional prefrontal cortex, meaning they have no ability to filter out background noise or distractions. To them, the world is \"loud\" and raw; everything is an all-encompassing event. This creates a heavy reliance on \"social referencing.\" Because they haven't yet learned to categorize sensations as \"dangerous\" or \"safe,\" they look to their caregivers to define reality. If a baby bumps their head and looks at their parent to see a look of horror, the baby interprets the sensation as a disaster. If the parent smiles, the baby continues playing. In this sense, the parents act as the baby's external prefrontal cortex, providing the emotional context that the baby's own brain cannot yet generate. **The Memory Trade-Off** Finally, this brings us back to the mystery of the missing memo","url":"https://doi.org/10.5281/zenodo.19432267","authors":["Rosehill, Daniel","Gemini 3.1 (Flash)","Chatterbox TTS"],"tags":["podcast","ai-generated","my weird prompts","child-development","sensory-processing","neuroplasticity"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.19432267","addedAt":"2026-08-31T06:34:52.122Z","updatedAt":"2026-08-31T06:34:52.122Z"},{"id":"doi:10.5281/zenodo.20848866","name":"Mind City","source":"datacite","abstract":"The Arrival: Plugging into the Cities Hub Your date begins at your physical desk.

In this work, we introduce a 3D-printable dataset of mathematically defined textures designed to be fabricated reliably across different printers and filament types. The dataset consists of six parametrically generated surface patterns derived from combinations of sine-wave and Fourier-based functions, giving controlled variation in spatial frequency, amplitude, and directional structure. We evaluate the reproducibility of these textures across three popular 3D printers and multiple filament types by measuring variance in images captured using an optical TacTip sensor under controlled contact conditions. Our results show that print quality, particularly peak sharpness and stringing, affects tactile variance, with higher-end printers producing significantly more consistent signatures. Classification experiments using neural networks and PCA-based models further demonstrate that high-quality prints support strong within-printer generalisation, while cross-printer generalisation remains challenging due to geometric inconsistencies.

However, the design of such systems remains challenging. Conventional approaches often suffer from complex multilayer structures, intricate wiring, high cost, and poor scalability, making it difficult to realize full-body tactile sensing with real-time, low-latency detection while maintaining minimal computational load on the robot's main processor. In this work, we present a simple, scalable and hardware friendly tactile sensing system for a companion humanoid robot based on the self-capacitance principle. The proposed sensor system employs a single conductive fabric layer with a conductive fabric wire architecture and does not require intricate electrode patterning. Scalability was demonstrated by fabricating a 100-point sensor array on a flexible printed circuit (FPC). Evaluation across sampling frequencies showed that 10 Hz is insufficient and misses transient events, whereas 100 Hz and 1000 Hz reliably capture and clearly distinguish all interaction types: gentle touch, slow tapping, fast tapping, and hitting. A decision-tree classifier was implemented directly on the FPGA, offloading real-time inference from the Raspberry Pi 4 with minimal latency and negligible power overhead. This design fully meets the tactile sensing requirements of the HIRO-chan robot and is well-suited for full-body tactile sensing in HIRO-chan and other companion robots.","url":"https://doi.org/10.48550/arxiv.2606.25348","authors":["Ali, Mohsin","Sumioka, Hidenobu","Ikemoto, Shuhei"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.25348","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.21268/20260618-0","name":"Photolithographic fabrication of polymer-based photonic sensor systems for multi-scenario applications","source":"datacite","abstract":"Diese Dissertation präsentiert einen photolithographischen Fertigungsablauf für verschiedene photonische Mikrostrukturen und Sensorsysteme unter Verwendung von Polymer-Photoresists.

By immersion, we mean that during the development of a new product, it is more and more required to stimulate several senses of the user so as to make the product more attractive. The sense of touch does not escape the rule and is more and more considered. Definitely democratized by its integration in smart phones with touchscreens, the haptic feedback allows enhancing the human-machine interactions in many ways. For instance by improving the comfort of use of a button through the modification of its force feedback. It can also offer an interactive experience during the manipulation of digital information and even improve the communication, particularly through the internet and for blind people, with the introduction of non-verbal signals. For these reasons, the present thesis focuses on the conception of multi-finger haptic devices, a new kind of peripherals integrating multiple actuators and capable of providing a fully programmable force feedback to the user's fingers. A global methodology is presented, outlining the different constituents necessary for their conception: actuator, sensor, control, communication and software user interface. Then, generic tools corresponding to the two first elements are presented. An accurate modeling of miniature electromagnetic short-stroke actuators is made possible thanks to the combination of 3D finite element modeling (FEM) and design of experiments (DOE). The non-usual behavior of magnetic flux lines in miniature actuators with relatively large airgaps imposes to avoid simplified analytical models and to use the reliable results of finite elements. The long computation times required by 3D FEM are balanced by the use of selective DOE making the modeling methodology easily adaptable, rapid and accurate. The parametrical model of the force provided by the modeling methodology is then integrated in a full parametrical setup allowing for the optimization of the actuator force using a conventional algorithm. The advantage of the parametrical optimization is that complementary non-linear constraints such as weight and temperature can be added, making the model multi-physic. Then, several original position measurement techniques using existing sensors are developed including a low-cost custom single-photointerrupter sensor allowing for direction discrimination for fast-prototyping and a hybrid sensing method using tiny Hall sensors and taking advantage of the leaks of the main actuator magnet. Two innovative self-sensing methods are then presented, allowing for the measurement of the mover position of linear short-stroke actuators. The first solution estimates the position of the coil by measuring the acceleration through the back emf. However in this case, a constant acceleration is required, which strongly restrains the application scope. The second solution allows for a real-time measurement of the position thanks to a passive oscillating RLC circuit influenced by the variation of the coil impedance. All the solutions presented are low-cost, compact and require few computation resources. Finally, in order to illustrate the methodology proposed along the thesis, several prototypes are fabricated, giving an overview of the possibilities offered by multi-finger haptic devices. A haptic numeric pad is notably used in an experiment made in collaboration with the University Service of Child and Adolescent Psychiatry in Lausanne with the aim of improving the impaired emotional processing of psychotic adolescents. Moreover, the successful identification of several touch sensations on the same haptic pad lays the first stones of a new tactile language.","url":"https://doi.org/10.5075/epfl-thesis-5485","authors":["Savioz, Grégory"],"tags":["Multi-finger haptic devices","force feedback","design of experiments","3D finite element modeling","miniature short-stroke actuators","position detection","self-sensing","tactile language"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2012","doi":"10.5075/epfl-thesis-5485","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.48550/arxiv.2606.18959","name":"TactSpace: Learning a Physics-enriched Shared Latent Space for Tactile Sim-to-Real Transfer","source":"datacite","abstract":"Tactile sensing provides direct measurements of contact interactions that are essential for robotic manipulation. However, current simulators lack the fidelity to faithfully model the complex deformation and transduction mechanics of tactile sensors, severely hindering sim-to-real transfer in robot learning pipelines. To address this challenge, we propose a multi-modal representation learning framework that aligns heterogeneous tactile modalities within a shared latent space, eliminating the need for accurate raw-signal simulation while preserving relevant contact information. Our approach employs modality-specific encoders to project diverse tactile observations, such as simulated penetration depth and real-world capacitance, into a common embedding space. The model is trained using self- and cross-reconstruction objectives alongside contrastive alignment, encouraging modality-invariant yet information-rich representations. We evaluate the learned embeddings on indenter shape identification, force prediction, and geometric reconstruction tasks, training exclusively in simulation and testing directly on real sensor measurements. Our results demonstrate zero-shot sim-to-real transfer across physically dissimilar representations. Furthermore, incorporating multi-physics simulation modalities yields more informative embeddings that transfer across diverse downstream tasks, demonstrating a 16.7% reduction in force prediction error and a 45.8% reduction in shape reconstruction error.

Such sensors have proven effective for robotic fingertip manipulation and contact sensing. However, because GelSight employs photometric stereo with RGB LEDs, it does not measure absolute depth directly but instead infers it by integrating estimated surface gradients, which can accumulate reconstruction errors; in addition, it becomes increasingly difficult to calibrate as the sensing area grows, and its depth accuracy is challenged on highly reflective or transparent objects. To overcome these drawbacks, we propose a fringe-projection-based contact measurement technique that performs triangulation-based 3-D reconstruction on a coated silicone contact surface, providing dense per-pixel surface geometry and full-field 3-D shape measurement over the contact region. By integrating high-accuracy digital fringe projection into the sensor, our approach simplifies calibration over larger areas and enhances depth precision for complex surfaces. Experimental results, including a direct comparison with a GelSight Mini sensor, a sphere-fitting accuracy evaluation, and an uncertainty analysis, confirm that the proposed method significantly improves the accuracy and stability of structured-light-based 3-D measurements, allowing reliable reconstruction of objects with diverse optical properties.","url":"https://doi.org/10.48550/arxiv.2606.17438","authors":["Yeo, Ingu","Chi, Hyung-Gun","Hyun, Jae-Sang"],"tags":["Computer Vision and Pattern Recognition (cs.CV)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2606.17438","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.48550/arxiv.2606.09777","name":"AetheRock: An Arm-Worn Robot Teaching System for Force-Guided Vision-Tactile Learning","source":"datacite","abstract":"Force and tactile sensing are indispensable in contact-rich manipulation.

However, for contact-rich scenarios, these TLMs struggle to understand the physical properties of dynamic objects, such as rotation and sliding directions. For instance, our preliminary experiments reveal that popular TLMs, such as Sparsh and AnyTouch2, exhibit weak performance on basic rotation direction reasoning from GelSight Mini tactile data. This surprising gap inspires us to explore a novel research question: Can we inject physically grounded geometric priors into TLMs to enable reliable contact orientation reasoning of dynamic object properties? To this end, we propose GeoTLM, a novel geometric representation-guided TLM for the perception of dynamic contact events. Our key idea is to preserve and structure tactile shear-field geometry before language-level reasoning, rather than forcing low-resolution tactile tokens into fragile closed-form physics operators. To achieve this, we propose a lightweight (only 14k parameters) yet novel Differentiable Geometric Representation (DGR). Specifically, DGR learns a contact-mask-guided representation in the shear field and aggregates it through an antisymmetric seven-region pooling design, motivated by the physical intuition that rotational contact produces antisymmetric deformation patterns. We conduct experiments on two representative tasks: rotation direction and sliding direction reasoning. Extensive experiments show that GeoTLM improves novel-object rotation accuracy by +14.6% and real-sensor sliding accuracy by +16.2% over the same backbone without the geometric encoder.

Conventional tactile sensing methods, reliant solely on spatial force values, have met with inconsistent results when addressing the complex cutting conditions in red meat processing. The variability inherent in red meat workpieces, coupled with the deformations induced by processing forces, necessitates an innovative machine perception approach to match the adaptability required in red meat processing tasks. This research explores an alternative approach leveraging temporal sensory data to discriminate meat tissues and tissue interfaces in real-time, thereby informing the trajectory of the cutting tool relative to the position of the deforming meat tissues. The strategy correlates unique characteristic force transients in the force data with predefined key cutting events of the task. While the thesis focuses on developing and validating the tactile perception strategy through experimental setups, it does not extend to full deployment in a robotic system. The methodology has been validated through experimentation using a custom-designed test rig including a 6-axis robotic manipulator, 6-axis force sensor, and high-resolution cameras. The results showed high precision in identifying unique force transients in the data and the key cutting moments in the performed task relative to the cutting tissues and tissue interfaces involved, which were consistent across cuts on comparable tissue arrangements. These principles are relevant across trimming and separation operations, where following tissue interfaces that are not visible during the operation is necessary. The forces exerted at the cutting edge of the knife indicate when the knife is approaching an interface, while the orthogonal side forces detect the behaviour of the deformable meat tissues causing the knife to deviate from a predefined cutting path. The results have enabled the proposal of a simplified machine perception strategy for trimming striploin steak by cutting relative to the real-time position of tissues and tissue interfaces. The investigation has produced new understanding and knowledge on guiding cutting in meat along tissue interfaces, using correct interpretation of force feedback to formulate judgment and cutting strategy ready to be executed.

Nevertheless, learning such tactile-only policies for real robots remains challenging due to the tactile sim-to-real gap and the limited expressiveness of sparse tactile signals. To bridge this gap, we propose a framework for tactile-only blind grasping that is deployable on a physical multi-fingered robotic hand. Our approach combines three key components. First, we introduce a Real2Sim tactile calibration pipeline that constructs a contact-calibrated digital-twin simulator capable of reproducing real tactile signals. Second, we improve the expressiveness of sparse tactile observations using a layout-aware tactile encoder, which incorporates sensor-geometry priors through self-supervised pretraining. Third, to improve generalization to unseen objects, we train object-specific reinforcement-learning experts in the calibrated simulator and aggregate their successful grasp trajectories into a tactile-conditioned Diffusion Policy. We evaluate our method on a physical LEAP Hand equipped with distributed tactile sensing across 10 seen and 10 unseen objects. The deployed policy achieves a 27\\% real-world grasp success rate across all 20 objects, without real-world grasping demonstrations or visual input. Simulation ablations show that layout-aware tactile pretraining improves grasping performance, while sensing-level evaluations confirm that Real2Sim calibration increases the consistency of tactile contact events between simulation and hardware. Together, these results suggest that contact-event calibration, geometry-aware tactile representation learning, and diffusion-based policy aggregation provide an effective path toward tactile-only blind grasping on real dexterous robotic hands.

As a result, they are often data-inefficient and generalize poorly when visual observations are degraded. To address this limitation, we propose a framework that explicitly grounds physical contacts in the image domain. Using robot forward kinematics and camera calibration, we project tactile sensor locations directly onto the RGB image plane. We then render force-modulated Gaussian saliency maps to model spatial uncertainty arising from kinematic and calibration errors. By integrating these 2D spatial anchors through a zero-initialized conditioning architecture, our method injects physical contact priors into standard visual backbones while preserving pre-trained visual representations. We evaluate our method on six dexterous manipulation tasks in both simulation and the real world under severe visual occlusions. Real-world experiments show that explicit RGB-S grounding in the image domain improves real-world occluded manipulation success rates by $26.7$ percentage points over the strongest implicit visuo-tactile baseline, suggesting its improved spatial reasoning and robustness to occlusion.

Central to our approach is a latent space arithmetic strategy that explicitly disentangles contact geometry from sensor-specific optical properties. Unlike methods that require recalibration for every new unit, this disentanglement allows SPLIT to adapt to diverse DIGIT backgrounds and even transfer data to distinct sensors like the GelSight R1.5 without full model retraining. Beyond this adaptability, our approach achieves faster inference speeds than existing alternatives.

Angesichts der hohen geforderten Oberflächenqualitäten sowie Form- und Lagetoleranzen am Bauteil ist es essenziell, den Schleifprozess zuverlässig zu überwachen und flexibel auf Veränderungen zu reagieren. Die direkte Messung des Schleifscheibenverschleißes während des Schleifprozesses stellt eine große technologische Herausforderung dar. Aufgrund einer Vielzahl an Störgrößen (Kühlschmierstoff, Späne, etc.) können optische oder taktile Messsysteme nicht verwendet werden. Im Rahmen der vorliegenden Arbeit wird ein neuer Ansatz der Messung des Radialverschleißes von profilierten Schleifscheiben verfolgt. Es wird ein neuartiger Radarsensor eingesetzt, der im frequenzmodulierten Dauerstrichbetrieb in einem Frequenzbereich von 82 GHz bis 99 GHz arbeitet. Die Radartechnologie ermöglicht eine berührungslose Messung mit gleichzeitig hoher Auflösung, ohne von prozessbedingten Störgrößen beeinflusst zu werden. Mithilfe einer dielektrischen Linse wird das Radarsignal auf einen Messfleck mit einem Durchmesser von 5 mm fokussiert. Für eine direkte In-Prozess Messung des Schleifscheibenverschleißes wurde ein Messsystem konzipiert und in eine Versuchsmaschine integriert. Die Messgenauigkeit des Systems beträgt bis zu ±1,7 µm, wobei die Schleifscheibenspezifikation das Messergebnis nicht beeinflusst. Messungen am geraden Schleifscheibenprofil korrelieren unter realen Prozessbedingungen sehr gut zwischen den Messdaten des Radarsensors und dem, über ein Einstechverfahren bestimmten, Verschleiß der Schleifscheibe (Plättchenmethode). Die berechneten Ausgleichsgeraden beider Verschleißkurven weichen nach einem Meter Schleifweg im Mittel um 6,1 µm voneinander ab. Mit dem Steigungswert der Verschleißkurven wurde ein Kennwert ermittelt, mit dem sich unterschiedliche Schleifscheibenspezifikationen bezüglich Ihres Verschleißverhaltens vergleichend bewerten lassen. Dadurch lässt sich der Einfluss der Einstellparameter (Schnittgeschwindigkeit, Vorschubgeschwindigkeit und Eingriffstiefe) auf das Verschleißverhalten von Schleifscheiben bestimmen und der Zerspanprozess optimal auslegen, weil die Verschleißauswirkungen sofort dokumentiert werden. Durch ein Abscannen der Schleifscheibenoberfläche mit dem Sensor kann ein digitaler Zwilling der Schleifscheibe erstellt werden. Dadurch wird ein virtuelles Abbild der Schleifscheibe erstellt, anhand dessen der Verschleißzustand der Schleifscheibe dargestellt und der optimale Zeitpunkt für den Abrichtvorgang bestimmt werden kann.

These controllers are constructed using trajectory optimization with respect to locally-linear time-varying models learned directly from sensor data. In some cases, we initialize the optimizer with human demonstrations collected via teleoperation in a virtual environment. We demonstrate that such controllers can perform the task robustly, both in simulation and on the physical platform, for a limited range of initial conditions around the trained starting state. We then consider two interpolation methods for generalizing to a wider range of initial conditions: deep learning, and nearest neighbors. We find that nearest neighbors achieve higher performance. Nevertheless, the neural network has its advantages: it uses only tactile and proprioceptive feedback but no visual feedback about the object (i.e. it performs the task blind) and learns a time-invariant policy. In contrast, the nearest neighbors method switches between time-varying local controllers based on the proximity of initial object states sensed via motion capture. While both generalization methods leave room for improvement, our work shows that (i) local trajectory-based controllers for complex non-prehensile manipulation tasks can be constructed from surprisingly small amounts of training data, and (ii) collections of such controllers can be interpolated to form more global controllers.

However, currently, methods based on different sensors, such as vision, lidar, audio, inertial measurement units (IMU), and tactile sensors generally require huge computing resources for data processing, online training, and recognition, and the performance tends to degrade once there are outlier data that do not exist in the prior training dataset. To solve this problem, inspired by the animals, such as rats and seals, just relying on whiskers to perceive information about their surroundings and survive in dark and narrow environments, we explore the physical whisker-based reservoir computing for quick and cost-efficient mobile robots’ environment perception and navigation. This thesis has creatively solved a machine-learning terrain classification problem by using a tapered ‘electro-mechanical’ whisker-based reservoir computing system for the first time in the world. The first analysis comprises designing a straight whisker sensor with one Hall sensor in the base and evaluating its nonlinear interaction dynamics which will have one dominant frequency at the vertical perturbation frequency of the sensor base. This nonlinear dynamic feature is used in a deep multi-layer perceptron neural network to classify terrains. We achieved an 85.6% prediction success rate for seven flat terrain surfaces with different textures at 0.2m/s. Therefore, a tapered whisker-based reservoir computing (TWRC) system using a tapered whisker sensor with three Hall sensors along the axis is proposed. The results demonstrated that such compliant tapered mechanical whisker systems could achieve real-time perception using nonlinear vibration dynamics and providing morphological computation power to achieve frequency separation in the time domain simultaneously. Then, by running a numerical analysis and experiments, it was found that external terrain stimuli of different roughness and hardness will produce unique whisker reservoir features and different whisker axis locations and motion velocities provide variable dynamical response information. We achieved a prediction success rate of 94.3% for six terrain surface classification experiments and 88.7% for roughness estimation of the unknown terrain surface at a steady speed of 0.2m/s.Moreover, a tapered whisker-based semi-supervised reservoir computing (TWSSRC) system is proposed to reveal that the whiskered robot can learn from prior physical experiences through cost-efficient self-supervised reservoir computing to achieve auto-labelling of new terrain, terrain classification, and terrain roughness estimation. The experimental results show that this novel approach is capable of successfully adapting well to unknown terrains based on the tapered whisker reservoir outputs and detecting new terrains with high accuracy, achieving 84% accuracy over six terrains with carpet representing the new terrain class. Depending on the computational superiority of the TWSSRC system, an active improved-TWMC algorithm including an overlapping-window-based decision module is designed, which could achieve active rapid object classification, even for the extremely similar sandpaper including external disturbances. Finally, a real-time terrain identificationbased navigation method is proposed using an onboard tapered whisker-based reservoir computing (TWRC) system rather than an external computer. The results experimentally demonstrate that our proposed algorithm could cost-efficiently achieve highly accurate real-time terrain classification results, and analyzed and demonstrated experimentally how the mobile robot can be controlled by speed to elicit unique frequency domain responses in a whisker sensor to help surface identification.

In this work, we introduce Center-of-Pressure (CoP), an effective tactile representation grounded in physical principles that preserves dense contact information while maintaining robustness for sim-to-real transfer. To support this representation, we propose a sensor calibration scheme based on differentiable dynamics, enabling the estimation of taxel orientations without requiring ground-truth force measurements. We evaluate CoP on two blind, challenging contact-rich manipulation tasks: peg-in-hole insertion and ball balancing. Across both tasks, policies conditioned on CoP achieve zero-shot sim-to-real transfer on a multi-fingered hand, and outperform both coarse binary-contact and raw-taxel baselines. Analysis of learned policy states further suggests that CoP-conditioned policies encode task-relevant physical properties, such as object mass, as an emergent byproduct of control.","url":"https://doi.org/10.48550/arxiv.2605.28812","authors":["Pan, Jiahe","Coros, Stelian","Malik, Jitendra","Lin, Toru"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","Machine Learning (cs.LG)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2605.28812","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.48550/arxiv.2605.28412","name":"Tactile-Proprioceptive Sensor Fusion for Contact Wrench Estimation in Whole-Body Physical Human-Robot Interaction","source":"datacite","abstract":"Direct physical guidance is a natural means of teaching and interacting with robots, and robotic skins make a key contribution by enabling sensitive contact sensing and localization.

Existing tactile-language models primarily rely on supervised or contrastive objectives, which limits their capacity to ground predictions in physical evidence or rectify misleading visual priors. Tactile reasoning introduces two modality-specific challenges: the ordinal nature of physical attributes (e.g., hardness, roughness) and the cross-sensor distribution shifts inherent in optical tactile hardware. In this work, we introduce TouchReason-1M, a large-scale multimodal dataset comprising over 1M synchronized tactile pairs across four distinct sensors, and TouchReason-Bench, a rigorous framework for evaluating tactile perception and visual-tactile conflict resolution. Building upon these, we propose Touch-R1, a tactile reasoning MLLM based on Qwen2.5-VL-7B. Touch-R1 is trained via a tactile-grounded GRPO objective that combines ordinal-aware accuracy, cross-sensor physical consistency, structured-format control, and an input-side tactile grounding objective. Specifically, the tactile-use reward assigns credit only when authentic tactile inputs yield superior correctness relative to counterfactual controls where the tactile stream is removed, shuffled, or noise-masked. On TouchReason-Bench, Touch-R1-7B outperforms Octopi-13B by 18.4\\% and GPT-4o by 24.7\\% on average.

This paper presents the first systematic framework for quantifying the contribution of individual tactile sensors to deep reinforcement learning (DRL) policy performance. We propose a two-stage approach: a coarse empirical pruning phase that reduces the sensor count on the Shadow Hand from 92 to 21 while retaining 93\\% task performance, followed by a fine-grained active learning phase that combines Gaussian Process Regression (GPR) with Lasso regression to rank the functional importance of each remaining sensor. Our analysis reveals that sensors on the thumb, ring finger, and little finger dominate manipulation performance, while middle-finger sensors exhibit negative contributions -- actively degrading policy learning. Ablation studies across three manipulation tasks (block, egg, and pen) confirm that a 14-sensor configuration preserves over 90\\% of the full-array performance. Zero-shot transfer experiments on two novel objects and cross-platform validation on the Allegro and Leap Hand further demonstrate that the identified importance rankings generalize across tasks and robot morphologies. These findings establish quantitative deployment guidelines that enable practitioners to select cost-effective sensor configurations with predictable performance trade-offs.","url":"https://doi.org/10.48550/arxiv.2409.20473","authors":["Guo, Haoran","Wang, Haoyang","Li, Zhengxiong","Bai, He","Tao, Lingfeng"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.48550/arxiv.2409.20473","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.48550/arxiv.2605.21976","name":"TacO: Benchmarking Tactile Sensors for Object Manipulation","source":"datacite","abstract":"Vision-based learning from demonstrations has achieved remarkable success in enabling robots to perform manipulation tasks and high-level semantic reasoning, yet it remains insufficient for complex, contact-rich manipulation. While there is broad agreement that tactile sensing improves manipulation, there is no empirical guidance on which tactile sensors are best suited for which manipulation tasks. In this paper, we provide a systematic, task-driven evaluation of tactile sensors for robot manipulation and propose a framework for selecting and evaluating sensors based on manipulation policy performance. Separate manipulation policies are trained for tactile sensors of four distinct modalities: visual, acoustic, magnetic, and resistive, across three tasks: pick-and-place with unknown mass, object reorientation, and plug insertion. For each task, an analysis of how sensor properties such as spatial resolution, shear sensing, and tactile representation, and the inherent material friction affect task performances is done. Rather than tactile sensing being universally beneficial in the same way, our results show that the usefulness of tactile information depends strongly on sensor modality, material properties, and the specific manipulation tasks. All of the tactile sensors, code, data, and hardware setup will be publicly available on the project website.","url":"https://doi.org/10.48550/arxiv.2605.21976","authors":["Zorin, Anya","Si, Zilin","Park, Myungsun","Park, Junsung","Buynitsky, Alexiy","Bhadang, Sachin","Park, Taejun","Yoon, Sohee John","Park, Yong-Lae","Kroemer, Oliver","Temel, Zeynep","Tolley, Michael T.","Yi, Sha","Wang, Xiaolong"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2605.21976","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.48550/arxiv.2605.21330","name":"Learning Robust Dexterous In-Hand Manipulation from Joint Sensors with Proprioceptive Transformer","source":"datacite","abstract":"In-hand object manipulation is a fundamental yet challenging capability for dexterous robots. Despite significant progress in dexterous manipulation, existing approaches rely heavily on vision or tactile sensing to track object states, while joint sensing -- the most readily available modality on any robotic hand -- remains largely overlooked, particularly for tendon-driven hands. In this paper, we study how far joint sensing alone can go by asking: (i) whether motor encoders or direct joint sensing provides better proprioceptive feedback, (ii) how to extract environment information from joint measurements, and (iii) whether joint-only control can achieve competitive real-world performance without external perception. We present the Proprioceptive Transformer (PT), an exteroceptive-free approach for continuous cube rotation on a tendon-driven dexterous hand that uses only joint sensing feedback. A teacher policy is first trained via reinforcement learning with privileged object information, then distilled into PT, which operates solely on joint position and velocity histories. The Transformer architecture effectively extracts implicit object state information from temporal patterns in joint sensor readings. Experiments on the real ORCA hand show that our approach achieves 3.1x higher rotation speed than baselines. We also demonstrate that our PT achieves a 23.4% lower RMSE for cube position estimation than the MLP baseline, indicating superior extraction of exteroceptive information from proprioceptive sources.","url":"https://doi.org/10.48550/arxiv.2605.21330","authors":["Yao, Senlan","Yang, Chenyu","Kim, Jaehoon","Sympetheros, Aristotelis","Katzschmann, Robert K."],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2605.21330","addedAt":"2026-08-31T06:34:52.123Z","updatedAt":"2026-08-31T06:34:52.123Z"},{"id":"doi:10.48550/arxiv.2605.20392","name":"VBT-MPC: Vision-Based Tactile MPC for Contour Following","source":"datacite","abstract":"Tactile sensing plays a key role in robotic manipulation, particularly in tasks like surface inspection.

To address this, we propose TLV-CoRe, a CLIP-based Tactile-Language-Vision Collaborative Representation learning method. TLV-CoRe introduces a Sensor-Aware Modulator to unify tactile features across different sensors and employs tactile-irrelevant decoupled learning to disentangle irrelevant tactile features. Additionally, a Unified Bridging Adapter is introduced to enhance tri-modal interaction within the shared representation space. To fairly evaluate the effectiveness of tactile models, we further propose the RSS evaluation framework, focusing on Robustness, Synergy, and Stability across different methods. Experimental results demonstrate that TLV-CoRe significantly improves sensor-agnostic representation learning and cross-modal alignment, offering a new direction for multimodal tactile representation.

To solve this challenge and achieve human level tactile perception, the novel hybrid event frame tactile sensor (Mixtac) is proposed in this paper by emulating the synergistic function of biological mechanoreceptors, which achieves normal force estimation. The prototype leverages events for high frequency force tracking and frames for long term accuracy. The Frame Guided Event Recurrent Network (FGER-Net) was proposed to fuse the two data streams. Frames were used by the net to correct event drift during training and guide high frequency predictions during inference. Experiments demonstrated an MAE of 0.04 N.

Durch die Steuerung der Endeffektoren im Operationsgebiet von einer entfernten Bedienkonsole aus verliert der Arzt jedoch die Möglichkeit, mithilfe seines Tastsinnes Interaktionskräfte und Gewebeeigenschaften wahrzunehmen und zu beurteilen. Hieraus ergeben sich für den Arzt und den Patienten Nachteile und Gefahren, die durch die Darbietung haptischen Feedbacks während der Teleoperation vermieden werden können. Gegenstand der vorliegenden Dissertation ist daher die wissenschaftliche Erarbeitung einer angepassten haptischen Bedieneinheit zum Einsatz in einem Teleoperationssystem für die Single-Port-Chirurgie sowie die Analyse von Methoden und Komponenten zur Sicherung des haptischen Feedbacks. Die Bedieneinheit umfasst die Funktion eines haptischen Eingabegerätes zur Steuerung eines Manipulators und die Funktion eines Ausgabegerätes zur Darbietung haptischen Feedbacks bezüglich wirkender Interaktionskräfte im Operationsgebiet. Diese Arbeit ist Teilprojekt des durch die Deutsche Forschungsgemeinschaft (DFG) geförderten Projektes FLEXMIN (WE 2308/13), dessen Hauptziel in der Erweiterung der Flexibilität minimalinvasiver Instrumente zur Durchführung von Operationen im konkreten Anwendungsfall der transanalen Rektumresektion besteht. Ein weiteres Teilprojekt (SCHL 532/6) umfasst das Single-Port-System, dessen Manipulatoren im Operationsgebiet des Darmes durch die in dieser Arbeit entwickelte Bedieneinheit gesteuert werden sollen. Die Manipulatoren des Single-Port-Systems basieren auf parallelkinematischen Mechanismen. Die Mechanismen ermöglichen die Positionierung und Orientierung eines Endeffektors im Raum, mit den vier in der Laparoskopie üblichen Freiheitsgraden, sowie die Aktuierung eines Greiffreiheitsgrades. Ausgehend vom Stand der Technik basiert der Entwurf der Bedieneinheit als Schnittstelle zum Menschen sowohl auf Grundlagen zur Physiologie und Ergonomie des Menschen als auch auf abgeleiteten Anforderungen, die sich aus der gewählten Systemstruktur des Teleoperationssystems und den kinematischen Eigenschaften des Single-Port-Systems ergeben. Hierzu werden die Mechanismen der haptischen Wahrnehmung diskutiert, für unterschiedliche Darstellungsvarianten haptischen Feedbacks grundsätzliche Lösungskonzepte erarbeitet und die Entwurfsziele zur Entwicklung haptischer Systeme abgeleitet. Geometrische Randbedingungen und zur Verfügung gestellte Freiheitsgrade der Bedieneinheit werden anhand der Struktur der Manipulatoren des Single-Port-Systems fixiert. Die entwickelte Bedieneinheit besteht aus zwei Bedienelementen zur beidhändigen Steuerung der zwei im Single-Port-System integrierten Manipulatoren. Die kinematische Grundstruktur der Bedienelemente ist passiv ausgeführt und gleicht der Struktur der kinematischen Hauptketten der Manipulatoren. Der Nutzer gibt durch seine Eingabe die Position des letzten Gliedes der kinematischen Kette vor. Zur Ausgabe von haptischem Feedback an den Nutzer wird die passive Grundstruktur durch aktive kinematische Mechanismen erweitert. Zur Darbietung eines räumlichen haptischen Feedbacks gelangen deltakinematische Mechanismen zum Einsatz. Sie lösen die von drei gestellfest montierten Aktoren erzeugten Signale im kartesischen Raum auf. Es werden zwei Mechanismen mit unterschiedlichen Entwurfszielen entwickelt, aufgebaut und messtechnisch evaluiert. Beide Mechanismen weisen einen Arbeitsraum von 200x200x150 mm³ auf und eignen sich zur Ausgabe von Kräften bis zu 20 N im Frequenzbereich bis etwa 50 Hz. Die Kraft wird mit einer Auflösung unterhalb der Wahrnehmungsschwelle der menschlichen Hand ausgegeben. Zur Steuerung und zur Ausgabe haptischen Feedbacks in den Freiheitsgraden Greifen und Rotation um die Werkzeugachse werden Nutzerinterfaces entwickelt, welche sich an die zuvor beschriebenen kinematischen Mechanismen ankoppeln lassen.

Here, we address these limitations by suppressing bending sensitivity at the device level and disambiguating tactile modes at the algorithmic level. We propose and fabricate a Ti 3 C 2 T x /graphene oxide (GO) sandwich sensor in which the conductive network is positioned near the neutral axis, thereby ensuring that bending induces negligible axial strain in the active layer. In contrast, out-of-plane pressing enlarges microcontacts, while in-plane stretching disrupts percolation pathways. We develop a composite-beam model to quantify neutral-axis alignment and the resultant bending immunity, realize the device via a straightforward casting process, and systematically characterize its electromechanical response under bending, pressing, nail pressing, and stretching. To further reduce modal ambiguity and improve tactile recognition, a lightweight one-dimensional convolutional neural network (1D-CNN) was introduced to classify temporal resistance signals from the sensor. Experimental results showed that the 1D-CNN achieved a high classification accuracy of 98.52% under flat-state training and testing conditions, and maintained 96.67% accuracy when evaluated on bending-state samples, demonstrating strong robustness against bending-induced interference. Together, the neutral-axis device architecture and the learning-based inference pipeline deliver high sensitivity to pressing and stretching while markedly suppressing the response to bending, thereby enabling wrist-worn pulse monitoring, soft-robotic joint sensing, and plantar pressure insoles.","url":"https://doi.org/10.3390/s26082471","authors":["Qi J","Gong T","Wang D"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26082471","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.3390/s26082341","name":"Development and Evaluation of a Data Glove-Based System for Assisting Puzzle Solving.","source":"pubmed","abstract":"Many hands-on tasks remain difficult to fully automate because they require human dexterity and flexible object handling.

Here, the Deqi microenvironment refers to the local, time-varying tissue domain around the needle in which mechanical deformation, microvascular perfusion, biochemical mediator release and electrophysiological activity are coupled and measurable. Conventional rigid sensing architectures cannot decode this process without disturbing it, because their stiffness can create mechanical mismatch with soft tissues, distort dynamic signals and provoke non-physiological inflammatory artifacts at the biological interface. This review examines the evolution from conventional rigid instrumentation toward flexible, multimodal bioelectronics for high-fidelity quantification of needling kinematics. Sub-micron electrospun nanomeshes, liquid metals and low-dimensional carbon networks enable the decoding of manipulation dynamics without tactile interference. These conformal arrays also support real-time, in situ mapping of the Deqi microenvironment across tissue biomechanics, local hemodynamics, biochemical metabolism and electrophysiological signaling. The translation of these physical inputs into systemic physiological responses is mediated by structurally defined mechanotransduction pathways, including the peripheral force-immune axis regulated by Ptgs2+ telocytes and central neuroanatomical projections such as the PROKR2-dependent vagal-adrenal circuit. Synthesizing the resulting high-dimensional data streams requires specialized computational architectures. Graph neural networks, multimodal Transformers and related AI frameworks can synchronize heterogeneous sensor inputs and support the construction of a computable Deqi Index for cautious clinical prognostication. Future progress will depend on scalable manufacturing, chronic bio-interface stability and clinically governed closed-loop control.

At sliding interfaces, frictional loading, tangential stress, and impending slip dominate sensing behavior. This work demonstrates three-dimensional finite element (3D-FE) and Poisson-Nernst-Planck (PNP) modeling of layered ionic polymer-metal composite (IPMC) artificial skin under finger-like reciprocating sliding contact. The layered structure consists of a Nafion-based IPMC core sandwiched between thin upper and lower electrodes. A rigid acrylic slider is used to simulate reciprocating finger motion relative to the surface of the IPMC skin. A time-dependent contact mechanics model is first utilized to simulate temporal variations in normal and tangential contact fields for various coefficients of friction. Electrochemical response is then determined in COMSOL Multiphysics by coupling ion transport and electrostatics in a PNP framework to predict the output sliding current. Parametric studies are used to investigate the dependence of sensor response on the coefficient of friction, reciprocating history, layer geometry, and transport parameters. From the results, it can be noted that the resulting parameter offers a robust and physically meaningful description of the magnitude of contact-induced shear stress under multi-mode loadings, yet retaining the capability of responding to the presence of friction-induced mechanical excitation. The current model is aimed at dynamic shear sensitivity detection in sliding contacts. It is not designed for texture discrimination or fragment identification tasks.

Traditional damage detection often relies on raw signal thresholds, lacking the functional integration of touch, pain, and damage found in biological systems. This study proposes a bio-inspired artificial skin model that separately evaluates these three states through a spatio-temporal anomaly detection framework. We developed an unsupervised model combining a Convolutional Autoencoder (CAE) and Convolutional LSTM (ConvLSTM) to learn the latent representations of tactile maps from intact skin. By quantifying spatial reconstruction and temporal prediction errors, the system generates individual scores for touch, pain, and damage. Pain is defined as an abstract signal of instantaneous abnormality, while damage is identified as a persistent structural deviation. We implemented a dynamic thresholding mechanism mimicking biological sensitization and recovery, with damage detection gated by a pain-flag constraint to minimize false positives. Experimental results across various conditions-including incisions (3-6 cm) and abrasions (10-30 times)-demonstrate that the model can distinguish between momentary noxious stimuli and sustained structural degradation. Quantitative evaluation shows that the proposed model achieves an Area Under the Curve (AUC) of 0.653, outperforming a threshold-based baseline and maintaining zero false positives under strong, non-damaging contact. Specifically, the system successfully mimics biological aftereffects and the pain-gating mechanism, where damage is only assessed in the presence of a pain-related trigger.

These features make them particularly relevant for wearable, implantable, and other edge-native neuroengineering applications. This review examines neuromorphic neuroengineering from four closely related perspectives: neuromorphic neurostimulation and adaptive actuation; tactile and sensory biointerfaces; spiking neural network (SNN)-based biosignal processing and state decoding; and wearable or implantable neuromorphic platforms. Across these domains, we highlight how neuromorphic systems may facilitate edge-native, closed-loop architectures that operate closer to the body and respond selectively to meaningful state changes. Neurorehabilitation is further discussed as an important translational context, as it involves long-term use, multimodal sensing, adaptive intervention, and substantial real-world deployment constraints.

Overall, neuromorphic approaches offer a promising systems-level pathway toward neuroengineering platforms that are not only computationally efficient but also adaptive, deployable, and responsive in real-world settings.","url":"https://doi.org/10.3390/s26103049","authors":["Sun Z","Mu A","Hao F","Wang H"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/s26103049","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/adma.74369","name":"Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications.","source":"pubmed","abstract":"Soft skins with reversible thickness morphing represent a distinct and underexplored class of adaptive material interfaces. Unlike conventional soft actuators that achieve motion through bending, elongation, or twisting, these systems enable out-of-plane deformation, producing localized protrusion, retraction, and programmable contact mechanics without rigid support structures. This review reframes thickness modulation not merely as an actuation outcome, but as a material-architecture strategy that couples energy transduction, geometry, and compliance to enable new modes of haptic interaction, morphological adaptation, and operation in confined or unstructured environments. We present a comprehensive synthesis of thickness-morphing soft skins, covering actuation stimuli, material platforms, structural architectures, fabrication strategies, modeling frameworks, and system-level integration. Particular emphasis is placed on hierarchical elastomer composites, origami- and kirigami-inspired designs, electrohydraulic and multimodal hybrid systems, and emerging data-driven control approaches that expand the functional design space. Despite rapid progress, key challenges remain in durability under cyclic loading, energy efficiency and autonomy, scalable manufacturing, and integration of sensing, actuation, and computation. Addressing these challenges will enable self-powered, fault-tolerant, and computationally intelligent soft skins capable of embodied perception and safe autonomous operation, positioning thickness morphing as a foundational design axis for next-generation haptics and soft robotic systems.","url":"https://doi.org/10.1002/adma.74369","authors":["Ozioko O","Akah C","Dahiya R"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1002/adma.74369","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.557Z"},{"id":"doi:10.1002/smll.75254","name":"Microstructural Engineering of Flexible Sensors: From Uniaxial to Triaxial Force Detection.","source":"pubmed","abstract":"Flexible force sensors rely on soft elastomers and stretchable conductors to conform to curved surfaces and convert mechanical loads into electrical signals.

A unified structural framework is established to connect uniaxial force sensing and triaxial force sensing through the deliberate regulation of deformation modes and load-transfer pathways. Porous, micropatterned, and hierarchical structures are examined for their roles in amplifying and stabilizing pressure-induced responses in uniaxial sensing, whereas distributed arrays and multilayer heterogeneous designs are analyzed for their abilities to enable directional discrimination, signal reconstruction, and normal-shear force decoupling in triaxial sensing. By comparing structure-mediated behaviors across major transduction mechanisms, general design principles are identified for improving sensitivity, linearity, and force decoupling, while the growing integration of structural engineering with data-driven signal reconstruction is also highlighted.

An analytical model was developed to describe the essential relationship between shear-induced displacements and the electrical response, providing insight into the design parameters and supporting the selection of geometry and materials. To test the sensor in real conditions, a dedicated capacitive readout circuit based on high-frequency excitation and synchronous demodulation was developed to robustly acquire capacitance variations while rejecting static offsets and parasitic effects. Several formulations for the interposed dielectric layer material were investigated, including viscous fluids and composite mixtures with high-permittivity nanoparticles, with the aim of improving electrical sensitivity while preserving mechanical stability. Experimental results obtained under controlled loading and sliding conditions demonstrate that the sensor is highly sensitive to changes in contact state and tangential interaction dynamics.

This complexity arises because the control system must maintain stable, adaptive, and coordinated motions under varying loads and unpredictable interactions. In human motor control, this stability is achieved through a biological sensorimotor closed loop, where tactile feedback continuously modulates neural signals to adapt to environmental changes. Inspired by these mechanisms for reducing grasp instability caused by external shocks, this study designed a multimodal controller termed the tactile, kinesthetic, and electromyography (EMG) bionic gripping controller (TKE-BGC). It integrates tactile, kinematic, and EMG information. Initially, multimodal data-encompassing tactile signals, joint angles, and EMG patterns-were collected from able-bodied users during tool manipulation via a data glove. Subsequently, the TKE-BGC model was trained on these data, utilizing a Transformer encoder to extract high-level features and a multilayer perceptron to predict joint angles in real time. Based on this controller, this paper presents a prosthetic control framework developed through human skill transfer. Unlike conventional fixed force or force follows strategies that struggle with dynamic impacts or tracking delays, this framework enables robust end-to-end adaptive control. Tested across 4 seen and unseen tool operation tasks, the proposed method demonstrated precise detailed performance. Specifically, it significantly reduced the number of tool drops and shortened task completion times compared to the baseline methods. Furthermore, it achieved human-like average contact forces and substantially lowered the user's physical workload, requiring noticeably less muscle effort than the force follows strategy (e.g., average EMG amplitude, 0.0023 versus 0.0124). By rapidly adjusting grip force through feedback and effectively mitigating instability, this research holds significant practical value in enhancing the daily independence of amputees and supporting their vocational rehabilitation and reemployment.","url":"https://doi.org/10.34133/cbsystems.0572","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.34133/cbsystems.0572","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/vetsci13050450","name":"Brushing as Environmental Enrichment in Dairy Cattle: Effects of Different Brushing Modalities on Behavior, Health, and Production.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/vetsci13050450","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/vetsci13050450","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/bios16060334","name":"Fiber-Optic Raman Sensor for Early Dental Caries Detection: Performance Evaluation and Robustness to Probe Positioning.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/bios16060334","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3390/bios16060334","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.3390/bios15090581","name":"In Vivo Study on the Safe Use of a Novel Intraoperative Sensing Tool for Tissue Stiffness Assessment in Endoscopic Surgery.","source":"europepmc","abstract":"","url":"https://doi.org/10.3390/bios15090581","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3390/bios15090581","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1016/j.isci.2026.115708","name":"Integrating multiple sensory modalities during dyadic interactions drives self-other distinction at the behavioral and electrocortical level.","source":"europepmc","abstract":"","url":"https://doi.org/10.1016/j.isci.2026.115708","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1016/j.isci.2026.115708","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.1063/5.0314573","name":"Research progress in flap temperature monitoring technologies and applications after transplantation.","source":"europepmc","abstract":"","url":"https://doi.org/10.1063/5.0314573","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.1063/5.0314573","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.4240/wjgs.v18.i2.116351","name":"Augmented intelligence in \"robotic\" liver surgery: Integrating augmented reality and artificial intelligence for real-time navigation and margin precision.","source":"europepmc","abstract":"","url":"https://doi.org/10.4240/wjgs.v18.i2.116351","authors":[],"tags":[],"confidence":0.8,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.4240/wjgs.v18.i2.116351","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.14288/1.0379736","name":"Novel Tactile Sensor Technology and Smart Tactile Sensing Systems: A Review","source":"datacite","abstract":"During the last decades, smart tactile sensing systems based on different sensing techniques have been developed due to their high potential in industry and biomedical engineering.

Deformable Tool Manipulation (DTM) further complicates this task by introducing additional uncertainties between the robot and its environment. While humans effortlessly manipulate deformable tools using touch and experience, robotic systems struggle to maintain stability and precision. To address these challenges, we present a novel State-Adaptive Koopman LQR (SA-KLQR) control framework for real-time deformable tool manipulation, demonstrated through a case study in environmental swab sampling for food safety. This method leverages Koopman operator-based control to linearize nonlinear dynamics while adapting to state-dependent variations in tool deformation and contact forces. A tactile-based feedback system dynamically estimates and regulates the swab tool's angle, contact pressure, and surface coverage, ensuring compliance with food safety standards. Additionally, a sensor-embedded contact pad monitors force distribution to mitigate tool pivoting and deformation, improving stability during dynamic interactions. Experimental results validate the SA-KLQR approach, demonstrating accurate contact angle estimation, robust trajectory tracking, and reliable force regulation. The proposed framework enhances precision, adaptability, and real-time control in deformable tool manipulation, bridging the gap between data-driven learning and optimal control in robotic interaction tasks.","url":"https://doi.org/10.48550/arxiv.2503.21491","authors":["Mahmoudi, Siavash","Davar, Amirreza","Wang, Dongyi"],"tags":["Robotics (cs.RO)","Systems and Control (eess.SY)","FOS: Computer and information sciences","FOS: Computer and information sciences","FOS: Electrical engineering, electronic engineering, information engineering","FOS: Electrical engineering, electronic engineering, information engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.48550/arxiv.2503.21491","addedAt":"2026-08-31T06:34:54.478Z","updatedAt":"2026-08-31T06:34:54.478Z"},{"id":"doi:10.5281/zenodo.19489194","name":"The Brain is a User Interface, not a Central Processor.

In such settings, vision and tactile sensing provide complementary information about object geometry, pose, inertia, stiffness, and contact dynamics, such as stick-slip behavior. However, these properties are only indirectly observable and cannot always be modeled precisely (e.g., deformation in non-rigid objects coupled with nonlinear contact friction), making the estimation problem inherently complex and requiring sustained exploitation of visuo-tactile sensory information during action. Existing visuo-tactile perception frameworks have primarily emphasized forceful sensor fusion or static cross-modal alignment, with limited consideration of how uncertainty and beliefs about object properties evolve over time. Inspired by human multi-sensory perception and active inference, we propose the Cross-Modal Latent Filter (CMLF) to learn a structured, causal latent state-space of physical object properties. CMLF supports bidirectional transfer of cross-modal priors between vision and touch and integrates sensory evidence through a Bayesian inference process that evolves over time. Real-world robotic experiments demonstrate that CMLF improves the efficiency and robustness of latent physical properties estimation under uncertainty compared to baseline approaches. Beyond performance gains, the model exhibits perceptual coupling phenomena analogous to those observed in humans, including susceptibility to cross-modal illusions and similar trajectories in learning cross-sensory associations. Together, these results constitutes a significant step toward generalizable, robust and physically consistent cross-modal integration for robotic multi-sensory perception.","url":"https://doi.org/10.48550/arxiv.2604.02108","authors":["Dutta, Anirvan","Tasciotti, Simone","Cusseddu, Claudia","Li, Ang","Poirazi, Panayiota","Gjorgjieva, Julijana","Burdet, Etienne","van der Smagt, Patrick","Kaboli, Mohsen"],"tags":["Robotics (cs.RO)","Machine Learning (cs.LG)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2604.02108","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.5167/uzh-280172","name":"Multi-Modal Computer- and Robot-Assisted Navigation in Spinal Surgery","source":"datacite","abstract":"Spinal disorders affect over 619 million people worldwide and are a leading cause of disability. In cases of severe pathology—such as spinal deformities, instability, or degenerative disc disease—surgical fusion is considered as the mainstay of therapy to restore spinal alignment and relieve chronic pain. A cornerstone of this procedure is the precise placement of pedicle screws (PSP), which demands millimeter accurate surgical execution to avoid neurological, vascular, or mechanical complications. Despite advances in computer-assisted navigation (CAN) and robot-assisted guidance (RG), current systems remain constrained by their reliance on single-modality data—typically optical tracking and intraoperative imaging—which makes them vulnerable to registration errors, anatomical shifts, and workflow deviations, particularly in minimally invasive settings. They also lack the flexibility to adapt to intraoperative surgical difficulties such as unexpected bleeding, tissue swelling, or altered exposure, which can compromise anatomical context and reduce the accuracy of navigation. Furthermore, these technologies still introduce additional costs and prolong surgical time due to required setup procedures, repeated imaging, and the need for highly specialized, additional personnel—factors that limit their broader clinical adoption, especially in resource-constrained environments. In contrast, surgeons dynamically construct an internal model of the surgical environment by integrating diverse sensory cues: visual inspection, tactile feedback, auditory signals, and procedural experience. This thesis is driven by the hypothesis that multi-modal navigation—integrating visual and non-visual sensing with learning-based inference—can overcome the rigidity and limitations of existing systems and enable safer, more adaptive, and radiation-free surgical guidance. To lay the foundation for this work, Chapter 2 presents a comprehensive review of intraoperative sensing and tissue classification techniques in orthopedics and neurosurgery. The review analyzes 60 studies across modalities, classification goals, algorithms, and validation methods, highlighting common limitations such as over-reliance on phantom models and lack of multi-sensor integration. Chapter 3 addresses the first research direction: non-visual sensing. A vibro-acoustic sensing framework was developed by integrating accelerometers and microphones. Using a fusion model, the system achieved 98.0% breach detection accuracy in ex-vivo porcine vertebrae, leveraging optical tracking for automated ground-truth labeling. This validates the feasibility of real-time cortical breach detection using auditory cues—emulating the natural sensory strategies used by surgeons. Chapters 4 and 5 focus on the second direction: the advancement of visual sensing for vertebral localization and reconstruction. Chapter 4 introduces a transformer-based 3D shape completion model that reconstructs vertebral anatomy from sparse stereo-vision point clouds. It achieved a mean Chamfer distance of 5.39 mm, an F-score of 0.85, and a surface signal-to-noise ratio of 22.9 dB against ground-truth CT in cadaveric testing. Chapter 5 presents a robotic ultrasound system for radiation-free bone surface reconstruction, combining force-controlled scanning with a deep-learning segmentation pipeline. The system achieved mean surface errors of 1.28 mm in phantoms and 1.74 mm in human cadavers, demonstrating potential for real-time vertebral mapping in percutaneous procedures. Chapter 6 addresses the final research direction: registration-free navigation. It evaluates whether the shape-completed vertebrae from intraoperative RGB-D data can be used to enable fully automatic pedicle screw planning directly. The system proposed candidate trajectories based solely on intraoperative reconstructions and achieved 100% Grade A screws in cadaveric validation—comparable to CT-based methods.

This problem is unsolved in unstructured environments, where the robot does not have access to precise models but must infer the state of the world with its sensors. The challenges for motion generation in these problems arise from the uncertainty prevalent in real world sensors, the different modalities that need to be considered, and real time constraints. Our approach in this thesis is to combine local feedback control with global planning under uncertainty to solve three different applications in manipulation. In the first part of this thesis we show the feasibility of a feedback-driven approach on a real world manipulation problem. We present an autonomous mobile manipulation system for bin picking. This system was an entry in the ``Amazon Picking Challenge'', where it outperformed 25 contenders. We evaluate strength and weaknesses of feedback and planning-based methods by comparing our system to others. In the second part, we review planning-based approaches, using sampling to efficiently search high-dimensional spaces. We present a novel planner for motion that exploits contact to reduce uncertainty. We propose a particle-based uncertainty model and search the combined space of configurations in free space and in contact. Our experiments show that our planners strategies are more robust strategies than solutions of traditional sampling-based planners because of the use of contact to reduce uncertainty. We extend this planner with a model for tactile feedback which allows it to localize objects just using the signal of contact sensors. In the third part, we discuss the continuous integration of sensor data into plans. To move efficiently in unstructured environments, robots must continuously adapt their plans in response to sensor data. We review trajectory optimization as a tool for path adaptation. We propose a novel approach to sensor-based motion generation based on a factorization in three tasks: 1) continuous path adaption, 2) continuous local planning of new motion alternatives 3) global planning with a model of an uncertain environment. This factorization allows us to generate robust motion in initially completely unknown environments with dynamic obstacles. In addition, we introduce an online learning method for manipulation control based on multi-modal sensors feedback. We conclude this thesis by combining all introduced techniques into a novel unifying framework for motion generation.","url":"https://doi.org/10.14279/depositonce-8588","authors":["Sieverling, Arne"],"tags":["004 Datenverarbeitung; Informatik","robotics","motion planning","mobile manipulation","Robotik","Bahnplanung"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.14279/depositonce-8588","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.17605/osf.io/v7gdz","name":"Scoping Review : The use of Haptic Wearable Devices in Healthcare Education.

Palpation requires complex haptic abilities such as force modulation, exploratory movement, and tissue discrimination(2). These skills are challenging to observe and evaluate reliably, making learning trajectories difficult to track and potentially variable across learners(3). Advances in haptic science and sensor-based technologies provide new opportunities to quantify tactile performance and support more individualized, precision education(4). Some sensor-enabled simulators and haptic devices have demonstrated the ability to distinguish novice from expert haptic behaviours and provide detailed performance metrics relevant for training(5,6). However, existing reviews focus on non-wearable, workstation-based haptic interfaces, primarily within laparoscopic surgery, and do not reflect the recent emergence of wearable haptic technologies (e.g., gloves, sleeves, soft exosuits). These devices differ fundamentally from fixed interfaces in portability, ecological validity, and integration into authentic clinical learning settings(7,8).

One of the channels of this body-to-brain communication is the vagus nerve, which carries signals from many organs to converge in the Nucleus Tractus Solitarius (NTS) in the brainstem, where they are relayed to brainstem nuclei for homeostatic control, and via thalamocortical projections to higher order structures such as the thalamus, hippocampus, amygdala, and insula (Craig, 2002; Critchley &amp; Harrison, 2013). In the insular and somatosensory cortices, interoceptive and exteroceptive signals are integrated into a cortical representation of the state of the body, giving rise to bodily sensations (Craig, 2009). Given its important role in communicating visceral information along the body-brain axis, stimulation of the vagus nerve (VNS) as a procedure for manipulating interoceptive processing is a promising tool for research into bodily self-consciousness and for clinical practice, particularly in psychiatric disorders associated with dysfunctions in self-consciousness (see Khalsa et al., 2018 for a review). Stimulation of the vagus nerve with an implanted device in the chest is already used in clinical settings as treatment for epilepsy (Conway et al., 2015) depression (Conway et al., 2015), heart failure (De Ferrari et al., 2011), obesity (Val-Laillet et al., 2010), and chronic pain (Kirchner et al., 2000). Recently there has been interest in a small branch of the vagus nerve that innervates part of the ear. Stimulation of this area, non-invasive transcutaneousauricular vagus nerve stimulation (taVNS), can produce some of the effects of invasive VNS, but safely without the need for surgery. Both procedures activate the same brain areas (Badran, Dowdle, et al., 2018; Frangos et al., 2015; Kraus et al., 2013) and taVNS is being increasingly used as an experimental tool to modulate cognitive and emotional function (Burger et al., 2016; Colzato et al., 2017, 2018; Jongkees et al., 2018; Sellaro et al., 2018). Importantly, a recent study (Villani et al., 2019) found that taVNS improved interoceptive accuracy in the heartbeat discrimination task (HDT; Whitehead et al., 1977), highlighting the potential of taVNS for manipulating interoception. To consolidate the use of taVNS as a method for manipulating interoceptive processing, it is important to examine its effect on manipulations of the interoceptive system and on higher levels of self-processing, such as the experience of body ownership (Paciorek &amp; Skora, 2020; Villani et al., 2019). Thus, the main objective of the study was to examine whether sham-controlled taVNS would affect participants’ experience of body ownership in a virtual version of the rubber hand illusion (RHI; Botvinick &amp; Cohen, 1998). Participants paid attention to the virtual hand while either 1) synchronous or asynchronous visuo-cardiac feedback was projected onto it, thus providing interoceptive cues that could increase sense of ownership towards the virtual hand, or 2) a rendered paintbrush stroked the virtual hand synchronously or asynchronously with the experimenter stroking the participants real hand with a real paintbrush. Methods and procedure Participants took part in two experimental sessions (real vs sham taVNS in counterbalanced order) separated by at least one week, lasting a maximum of 2 hours, including set-up and performance in the experimental tasks. The experiment was composed of separate stages: Cardiac interoception tasks Only during the first session participants first completed the heartbeat counting task, during which they had to mentally count their felt heartbeats in six trials of varying length, and the heartbeat detection task, during which they listened to 20","url":"https://doi.org/10.17605/osf.io/4wreb","authors":["Garfinkel, Sarah","Suzuki, Keisuke","Vabba, Alisha","Möller, Tim Julian","Doric, Milica","Critchley, Hugo"],"tags":["Life Sciences","Social and Behavioral Sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.17605/osf.io/4wreb","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.5281/zenodo.17664064","name":"未来の茶屋 / The Tea House of the Future: CollectiveOS Global Flagship & Open Science Hub — Tokyo","source":"datacite","abstract":"未来の茶屋 / The Tea House of the Future: CollectiveOS Global Flagship & Open Science Hub — Tokyo Executive Summary This foundational white paper establishes the architectural, operational, and philosophical parameters for \"The Tea House of the Future\" (Mirai no Chaya), a flagship facility located in Tokyo, Japan.

Two-dimensional (2D) materials often act as conductors and electrodes in electronic devices, holding significant promise in the design of high-performance, flexible electronics. Numerous studies have focused on harnessing the potential of these materials for the development of such devices. However, to date, the incorporation of 2D materials in flexible electronics has rarely been summarized or reviewed. Consequently, there is an urgent need to develop comprehensive reviews for rapid updates on this evolving landscape. This review covers progress in complex material architectures based on 2D materials, including interfaces, heterostructures, and 2D/polymer composites. Additionally, it explores flexible and wearable energy storage and conversion, display and touch technologies, and biomedical applications, together with integrated design solutions. Although the pursuit of high-performance and high-sensitivity instruments remains a primary objective, the integrated design of flexible electronics with 2D materials also warrants consideration. By combining multiple functionalities into a singular device, augmented by machine learning and algorithms, we can potentially surpass the performance of existing wearable technologies. Finally, we briefly discuss the future trajectory of this burgeoning field. This review discusses the recent advancements in flexible sensors made from 2D materials and their applications in integrated architecture and device design. The progress was summarized in the flexible electronics empowered by the two-dimensional materials, including electronic skins (for sweat and temperature sensors), gas sensors, touch pads, nanogenerators for mechanical energy collection, flexible supercapacitors and batteries, transistors and logic circuits, as well as memristors for neuromorphic computing.

We execute many varying tasks with the hands of which many are basic activities of daily life. Movement disorders in the upper limb can limit the execution of those tasks and impair the quality of life. One of the most common movement disorders is tremor, affecting 5.6% of the population aged over 65 with Parkinson’s Disease or Essential Tremor. In the overall population, approximately 2.2% are affected by Essential Tremor. More than 65% of those suffering from tremor in the upper limb present serious difficulties in performing activities of daily life. Currently, neither Essential Tremor nor Parkinson’s Disease is curable, and therefore, treatment is focused on relieving the symptoms to increase the quality of life of the patients. Medication is the most commonly used treatment, while deep brain stimulation is the most effective treatment but is reserved for advanced cases as it is highly invasive. As a large fraction of patients is either refractory to medication, drug intolerant, or not qualified for surgical treatment, alternative treatments are needed. Even with optimal medical or surgical intervention in tremor, patients will still require physical and occupational therapy interventions to promote full social participation. An alternative non-invasive symptom treatment is the mechanical suppression of the oscillation movement with tremor suppression orthoses. In wearables, including tremor suppression orthoses, the functionality contradicts the comfort and needs to be balanced. The use of a tremor suppression orthosis brings the dilemma of low comfort for the wearer due to non-optimized wearability. In the philosophy of technology, this trade-off between tremor suppression and wearability is called the dilemma of assistance and acceptance, whereas acceptance is defined as a combination of wearability and social factors. The objective of this thesis was to tackle the dilemma by maximizing wearability without reducing the tremor suppression efficacy of such tremor suppression orthoses. Therefore, two user groups were identified to tailor approaches to their needs. The intermittent user group requires a tremor suppression orthosis for activities of daily living occurring infrequently during the day. The continuous user group needs a tremor suppression orthosis for a variety of complex tasks performed consecutively throughout the entire day. In the first step, I conducted a systematic literature review to identify the weaknesses of current wearable tremor suppression orthoses for the upper limb and to identify the need for further research and developments. I identified 21 different orthoses concepts and prototypes, of which most of them concentrated on the wrist and elbow flexion and extension. They mainly relied on rigid structures and actuators while having tremor suppression efficacies for tremor affected people of 63% on average. I showed that most of the orthoses had low wearability by being bulky and heavy, with a non-adapted human-machine interface. For the intermittent user group, infrequently in need of tremor suppression, I developed a lightweight, textile-integrated orthosis. With a passive element in this orthosis, I modified the human wrist impedance. The working principle of the orthosis was based on a task adjustable, air-filled structure placed on the dorsal side of the wrist. I characterized the stiffness and damping properties of the orthosis with which the wrist impedance was modified. Furthermore, I evaluated the efficacy of the developed passive orthosis by analyzing the suppression of involuntary movements in the wrist of a tremor affected patient during different activities of daily living. I demonstrated that the soft orthosis reduced tremor power for daily living activities, such as drinking from a cup, pouring water, and drawing a spiral, between 74% and 82%. In the next step, I developed a controlled suppression orthosis for the continuous user g","url":"https://doi.org/10.3929/ethz-b-000561761","authors":["Fromme, Nicolas P."],"tags":["tremor","suppression","Orthosis","Human machine interaction","info:eu-repo/classification/ddc/600","info:eu-repo/classification/ddc/610","info:eu-repo/classification/ddc/620","Technology (applied sciences)"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.3929/ethz-b-000561761","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.48550/arxiv.2103.11123","name":"Force Sensing in Robot-assisted Keyhole Endoscopy: A Systematic Survey","source":"datacite","abstract":"Instrument-tissue interaction forces in Minimally Invasive Surgery (MIS) provide valuable information that can be used to provide haptic perception, monitor tissue trauma, develop training guidelines, and evaluate the skill level of novice and expert surgeons.Force and tactile sensing is lost in many Robot-Assisted Surgery (RAS) systems.

This scientific study investigates various perception modalities and techniques employed in humanoid robots, including visual, auditory, and tactile sensing by exploring recent state-of-the-art approaches for perceiving and understanding the internal state, the environment, objects, and human activities. Recent Findings: Internal state estimation makes extensive use of Bayesian filtering methods and optimization techniques based on maximum a-posteriori formulation by utilizing proprioceptive sensing. In the area of external environment understanding, with an emphasis on robustness and adaptability to dynamic, unforeseen environmental changes, the new slew of research discussed in this study have focused largely on multi-sensor fusion and machine learning in contrast to the use of hand-crafted, rule-based systems. Human robot interaction methods have established the importance of contextual information representation and memory for understanding human intentions. Summary: This review summarizes the recent developments and trends in the field of perception in humanoid robots. Three main areas of application are identified, namely, internal state estimation, external environment estimation, and human robot interaction.

However, detecting the cancer at an early stage can significantly improve the chances of successful treatment. CRC polyp miss rates are as high as 27% for serrated polyps and 34% for flat polyps, particularly because the morphological characteristics of polyps are patient-dependent. There is a need for sensing devices and computer aided diagnosis tools to assist clinicians in improving the detection and classification of CRC polyps. To address these limitations and mitigate the risks associated with CRC, we have developed a novel approach utilizing a vision-based surface tactile sensor (VS-TS) and a complementary artificial intelligence (AI) algorithms. The research presented in this report is published in [1, 2, 3] and under review at International Conference on Robotics and Automation (ICRA) 2023. In this study, we present the various iterations of our sensors and algorithms that led to the current version of our system. We designed realistic polyp phantoms representing the textures of the Paris (48 polyps) and Kudo (160 polyps) classification systems with varying stiffnesses to evaluate our system. Initially, using the first sensor iteration, we developed a support vector machine texture classification algorithm using histogram of oriented gradients as feature representation and t-Distributed Stochastic Neighbor Embedding algorithm for stiffness/material differentiation. In the next stage, we utilized a more advanced, pre-trained ResNet-18 architecture. We also developed the HySenSe, a hyper sensitive and high fidelity sensor, to minimize the applied forces and capture more detailed textures. With this sensor, we designed a computationally efficient and high-performing deep learning model utilizing dilated residual networks to classify pit-pattern or Kudo polyp textures. Finally, we developed a real-time polyp detection using YOLO v5 and the pit-pattern classification system. The initial SVM model achieved an accuracy of 93.75%, and we were able to isolate the hardest polyp material (M3) from softer, more similar materials (M1, M2). Utilizing the 1 ResNet-18 model, we achieved an accuracy of 92.88%. Lastly, the proposed model utilizing dilated residual networks model classified various pit-pattern textures with a 94% accuracy using a dataset of 160 unique polyps. 1.4 The results demonstrate the potential of our proposed approach as a promising diagnostic tool for the early detection and diagnosis of colorectal cancer. Our system has the potential to have a significant impact on the prevention and treatment of this disease. In the future, we aim to focus on training the models on excised human polyps and evaluating the performance of this system in a pre-clinical setting.","url":"https://doi.org/10.26153/tsw/45411","authors":["Venkatayogi, Nethra"],"tags":["colorectal cancer","artificial intelligence","tactile sensing","deep learning"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.26153/tsw/45411","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.18154/rwth-2023-02754","name":"Messunsicherheit bei der Messung aerodynamisch relevanter Bliskmerkmale durch Informationsfusion","source":"datacite","abstract":"Despite the setback, which aviation suffered in the recent past due to the coronavirus pandemic, air transport remains the only means of transport capable of covering long distances quickly. The fact that the engines used, in this case turbines, have a negative life cycle assessment, as well as the lack of a more efficient technology that could replace the kerosene currently used, means that large aircraft will have to continue to use combustion as an energy source in a window of about 15 to 20 years. Despite the positive historical record of developing new turbines such as turbo-fan and gear-fan, which have significantly reduced the average fuel burn per passenger or mass carried by increasing the bypass ratio (Fan- core engine ratio), this technology still has an energy balance that leaves potential for improvement. New prototypes of single-wing and V-wing aircraft are being tested that would allow an increase in propeller diameter (Fan) to core engine ratio (one propeller spinning slower and one core engine spinning at a high RPM) and thus a direct increase in bypass. But even these prototypes need time before they can replace models with turbines mounted under the wings. Therefore, reducing the length, diameter and number of stages of the core engines seems to be the best way to optimize the new generation of turbofans at the moment. Blisks (Blade Integrated Disk) are components used in the high compression area and are responsible for increasing the pressure of the air before it reaches the combustion chamber. However, despite the above requirements, this increase in pressure and consequently temperature can only be achieved by modifying the alloys used and new, more complex and aerodynamically efficient geometries. This represents a challenge for design, manufacturing and quality control. Measuring geometric requirements of blisks with tactile sensors on coordinate measuring machines (CMMs) is common practice. However, morphological effects typically cause errors in the compensation of the sensing ball as the sensor moves over complex geometries, primarily around the edge of the blade. Errors in the shape, position, effect of the sensing ball, and measurement strategy typically occur superimposed, making a differentiation of individual effects practically unfeasible. By using a digital twin, it is possible to simulate some of the above sources of error. With the help of a CMM simulator, an estimation of these effects, by introducing known deviations into the blisk CAD model, is possible. Understanding these morphological effects is an important step towards smart connected manufacturing. It also forms the basis for the comparison of different measurement principles, as well as the implementation of metrological traceability, which is an important point of quality assurance and measurement process capability. In this paper, as a first step, the author performs a historical review of the design features relevant to the aerodynamic control and efficient operation of compressor blades in order to understand the reasons and the measurement systems available at that time. With this information, a review of the state of the art is conducted, selecting the measurement systems of current industrial practice (CMM and SLP), which are used to systematically and methodically investigate the sources of uncertainty in the measurement. The reduction of the systematic components of the measurement uncertainty, caused by the incorrect position of the real compressor blade in relation to its CAD model, can be minimized by the fusion of the above mentioned measurement systems. Finally, the author compares the obtained results based on a standardized error of 95\\% and thus can answer the research questions defined in this thesis.","url":"https://doi.org/10.18154/rwth-2023-02754","authors":["Schmidt, Ânderson"],"tags":["620","Blisk","Koordinatenmessgerät","Luftfahrt","Messunsicherheit","Streifenlichtprojektion"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.18154/rwth-2023-02754","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.48550/arxiv.2206.11350","name":"Vision- and tactile-based continuous multimodal intention and attention recognition for safer physical human-robot interaction","source":"datacite","abstract":"Employing skin-like tactile sensors on robots enhances both the safety and usability of collaborative robots by adding the capability to detect human contact. Unfortunately, simple binary tactile sensors alone cannot determine the context of the human contact -- whether it is a deliberate interaction or an unintended collision that requires safety manoeuvres. Many published methods classify discrete interactions using more advanced tactile sensors or by analysing joint torques. Instead, we propose to augment the intention recognition capabilities of simple binary tactile sensors by adding a robot-mounted camera for human posture analysis. Different interaction characteristics, including touch location, human pose, and gaze direction, are used to train a supervised machine learning algorithm to classify whether a touch is intentional or not with an F1-score of 86%. We demonstrate that multimodal intention recognition is significantly more accurate than monomodal analyses with the collaborative robot Baxter. Furthermore, our method can also continuously monitor interactions that fluidly change between intentional or unintentional by gauging the user's attention through gaze. If a user stops paying attention mid-task, the proposed intention and attention recognition algorithm can activate safety features to prevent unsafe interactions. We also employ a feature reduction technique that reduces the number of inputs to five to achieve a more generalized low-dimensional classifier. This simplification both reduces the amount of training data required and improves real-world classification accuracy. It also renders the method potentially agnostic to the robot and touch sensor architectures while achieving a high degree of task adaptability.","url":"https://doi.org/10.48550/arxiv.2206.11350","authors":["Wong, Christopher Yee","Vergez, Lucas","Suleiman, Wael"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.48550/arxiv.2206.11350","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.48448/5943-3087","name":"Reprogrammable Liquid metal/NdFeB/Silicone Composite Magnetic Elastomer","source":"datacite","abstract":"Authors: Ran Zhao(3), (1), Houde Dai(1), (2), Guopeng Zhou(4), (1), Hanchen Yao(5), (2), Bing Zhang(6) (1)Quanzhou Institute of Equipment Manufacturing of Haixi Institutes, Chinese Academy of Sciences, Jinjiang, Fujian, China, (2)Fujian Institute of Research on the Structure of Matter, Chinses Academy of Sciences, Fuzhou, Fujian, China, 3Zhongyuan-Petersburg Aviation College, Zhongyuan University of Technology, Zhengzhou, Henan, China, 4Guangdong Technion- Israel Institute of Technology, Guangzhou, Guangdong, China, 5University of Chinese Academy of Sciences, Beijing, China, 6School of Energy and Intelligent Engineering, Henan University of Animal Husbandry and Economy, Zhengzhou, Henan, China Abstract Body: Hard-magnetic soft materials has a lot of application scenarios in the field of soft robots and flexible sensors. But, due to the coupling of magnetization process and manufacturing process, the functions of these devices can not be changed. Therefore, the technique of repeatedly program magnetic anisotropy on magnetic elastomer is of great significance for changing the functions of magnetic soft robot and sensor. This paper presented a reprogrammable mangetic elastomer based on Liquid-metal/NdFeB/Silicone composites. The NdFeB particles wrapped in gallium can be re-orientated by thermal-ssisted magnetic programming(Figs.1a-1c). Thus, the magnetization profile can be reconfigurated on the elastomer(Fig.1d).X-ray diffraction (XRD) analysis shows the phase composition of gallium, Silicone and Nd2Fe14B (Fig.2a). The elstomer's magnetic properties are tested by the comprehensive physical property measurement system (PPMS). The moment-temperature (M-T) curve shows the material's moment jumps at 303 K（the melt point of gallium)(Fig.2b). And the moment-magnetic field (M-H) curves indicate that the elastomer exhibit hard and soft magnetic properties respectively (Fig.2c), when the temperatureis lower (293 K) or higher (313 K) than the phase-transition temperature of gallium. A hexagon-shape robot was manufactured and then programmed to two modals of grasping and walking respectively(Figs.2d and 2e).The experimental results verify the reprogrammability of the proposed composite elastomer. The elastomer is expected to be used to manufacture multi-modal magnetic soft robot. References: H. Chung, A. M. Parsons, L.

This portfolio details the process and results of focusing on blindness and visual impairments, and improvements that can be made in the field of eyecare. The technical portion of this project contained the creation of a new wearable technology for those suffering from visual impairments, in order to provide feedback to users about unseen obstructions. It utilizes an array of sensors, motors, and speakers in order to provide tangible feedback to users about their surroundings. The full documentation and detail of the creation and testing of this device are included in the portfolio for the visually assistive hat. For the science, technology, and society (STS) research topic, the results aim to show an answer to the following question: what leads to women being more likely to suffer from visual impairments, such as cataracts and blindness, than men? These two topics and projects are closely linked together, as they aim to provide insight and solutions into the field eye care and the disparities within it. For the technical portion of this portfolio, this project focused on creating a hat that provides tactile and auditory feedback to blind and visually impaired individuals based on obstruction detection. This was done by embedding light detection and ranging (LiDAR) sensors into the hat and connecting them to a central microcontroller (MCU) board to process current surroundings. The device gathers information regarding a user’s surroundings from the front, sides, back, and any incline changes. Then, using the information provided by the LiDAR sensors, vibrating direct current (DC) motors were programmed to vibrate whenever their respective sensor detects an object and increases the vibration frequency as the object gets closer to the individual. Additionally, small piezo speakers will be mounted to the side of the cap and connected to the MCU to provide auditory feedback for users who may prefer to have auditory feedback. Lastly, the cap has a sensor that provides feedback whenever the user approaches steps or some type of change in surface elevation. The technical work involved in this portfolio ultimately aimed to mitigate issues found in alternative forms of visual assistants by creating a lightweight device the user can place on their head and not worry about holding. This project’s design provides the user with a fuller picture and awareness of their surroundings by monitoring obstructions from the user’s side or behind. The combined use of LiDAR and ultrasonic sensors help create a more effective and powerful obstacle detection system, as opposed to the use of video cameras or simply ultrasonic sensors alone. The STS research topic for this portfolio is centered around the discrepancies between genders within the field of visual degradation. Blindness and vision loss is a problem that affects millions of people around the world, and something that most people are likely to experience to varying degrees. As the world continues to age and average lifespans increase, visual impairments will only increase in frequency. Unfortunately, studies have shown that blindness is more common in women, specifically those over 50, than in men, and yet women are less likely to receive care for their eye problems. This portion of the portfolio aims to determine what leads to women being more likely to suffer from visual impairments, such as cataracts and blindness, than men. Official journals, governmental and educational papers, studies, and reports will be used to gather information about the current state of visual impairments across genders. This research is analyzed using the wicked problem framing technique to be able to assemble a complete breakdown of the problems surrounding women’s lack of access to eyecare, as well as providing an in-depth review of the inequalities acros","url":"https://doi.org/10.18130/w94p-1k95","authors":["Mary DeSimone"],"tags":["Blindness","Visual Impairments","Gender Inequality","LiDAR"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.18130/w94p-1k95","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.48550/arxiv.2109.11234","name":"The Role of Tactile Sensing in Learning and Deploying Grasp Refinement Algorithms","source":"datacite","abstract":"A long-standing question in robot hand design is how accurate tactile sensing must be. This paper uses simulated tactile signals and the reinforcement learning (RL) framework to study the sensing needs in grasping systems. Our first experiment investigates the need for rich tactile sensing in the rewards of RL-based grasp refinement algorithms for multi-fingered robotic hands. We systematically integrate different levels of tactile data into the rewards using analytic grasp stability metrics. We find that combining information on contact positions, normals, and forces in the reward yields the highest average success rates of 95.4% for cuboids, 93.1% for cylinders, and 62.3% for spheres across wrist position errors between 0 and 7 centimeters and rotational errors between 0 and 14 degrees. This contact-based reward outperforms a non-tactile binary-reward baseline by 42.9%. Our follow-up experiment shows that when training with tactile-enabled rewards, the use of tactile information in the control policy's state vector is drastically reducible at only a slight performance decrease of at most 6.6% for no tactile sensing in the state. Since policies do not require access to the reward signal at test time, our work implies that models trained on tactile-enabled hands are deployable to robotic hands with a smaller sensor suite, potentially reducing cost dramatically.","url":"https://doi.org/10.48550/arxiv.2109.11234","authors":["Koenig, Alexander","Liu, Zixi","Janson, Lucas","Howe, Robert"],"tags":["Robotics (cs.RO)","Artificial Intelligence (cs.AI)","Machine Learning (cs.LG)","Systems and Control (eess.SY)","FOS: Computer and information sciences","FOS: Computer and information sciences","FOS: Electrical engineering, electronic engineering, information engineering","FOS: Electrical engineering, electronic engineering, information engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.48550/arxiv.2109.11234","addedAt":"2026-08-31T06:34:54.479Z","updatedAt":"2026-08-31T06:34:54.479Z"},{"id":"doi:10.48550/arxiv.2012.02504","name":"Pose-Based Tactile Servoing: Controlled Soft Touch using Deep Learning","source":"datacite","abstract":"This article describes a new way of controlling robots using soft tactile sensors: pose-based tactile servo (PBTS) control.

To overcome the subjectivity of traditional sensory panels, our platform utilizes a tactile friction sensor to capture time‐dependent spreading dynamics with high precision. By applying exponential decay analysis to the raw frictional data, we extracted four physically interpretable parameters: static response peak, decay amplitude, decay rate, and plateau level. These parameters reflect distinct tactile characteristics such as spreading, lubrication transition, and residue. Multivariate regression analysis demonstrates a hierarchical predictive performance for tactile attributes. Primary attributes such as smoothness, stickiness, and thickness exhibited strong correlations with R 2 values exceeding 0.82. Secondary attributes maintained reliable predictive accuracy between 0.72 and 0.74. Notably, residue achieved a significant correlation of 0.62, quantifying a complex sensory dimension that is traditionally difficult to measure mechanically. These findings demonstrate that time‐dependent frictional dissipation more effectively represents tactile perception dynamics than conventional single‐point analyses. Overall, this approach provides a practical and reproducible framework for predicting multiple sensory attributes from a single measurement, with broad applicability in the digitization of cosmetic and pharmaceutical products.","url":"https://doi.org/10.1002/adsr.70159","authors":["Jeong Yu Lee","Meongjin Goh","Eunmi Kim","Jin Nam"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-05-12T10:39:13Z","doi":"10.1002/adsr.70159","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/aim65483.2026.11658239","name":"MagTip: Magnetic Tactile Fingertip Sensor for Contact Detection and 3D Localisation","source":"crossref","abstract":"","url":"https://doi.org/10.1109/aim65483.2026.11658239","authors":["Ugnius Bajarūnas","Antonia Tzemanaki","Benjamin Ward-Cherrier"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-08-25T19:08:28Z","doi":"10.1109/aim65483.2026.11658239","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.5954/icarob.2026.gs6-5","name":"Sleep Posture and Heartbeat Estimation Using a Flexible Tactile Sensor Sheet","source":"crossref","abstract":"","url":"https://doi.org/10.5954/icarob.2026.gs6-5","authors":["Hibiki Shimono","Kazuya Matsuo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-04-25T22:09:52Z","doi":"10.5954/icarob.2026.gs6-5","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1016/j.wear.2025.206422","name":"Estimation of cutting tool wear using an elastomeric tactile sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.wear.2025.206422","authors":["Ritin Mathews","Gregory Corson","Joshua Harbin","Christopher Tyler","Scott Smith"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-11-20T08:29:59Z","doi":"10.1016/j.wear.2025.206422","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/mems64181.2026.11419455","name":"CMOS-MEMS Tactile Sensor with Adjustable-Sensitivity Force Sensing and Proximity Detection","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mems64181.2026.11419455","authors":["Fuchi Shih","Mei-Feng Lai","Weileun Fang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-11T19:35:46Z","doi":"10.1109/mems64181.2026.11419455","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.20965/jrm.2026.p0764","name":"Double-Roller Tactile Image Sensor for Simultaneous Double-Sided Inspection","source":"crossref","abstract":"This paper proposes a surface inspection method using a double-roller tactile image sensor. The roller-type tactile image sensor provides high spatial resolution by employing a camera and enables continuous contact with the object surface via the rollers.

To address this limitation, we developed a double-roller tactile image sensor capable of capturing contact images from both sides by sandwiching the object between two rollers. The relationship between applied force and image response was investigated through sensitivity experiments using a force gauge and nylon thread. Experiments using models simulating food and foreign objects revealed that a sufficiently large response was obtained with a pressing force of 0.1 N even for small objects with a diameter of 0.25 mm, while differences in material hardness and foreign object size resulted in differences in the contact image. Furthermore, we performed an experiment using shrimp as an example of food inspection and confirmed that the proposed sensor can successfully capture images of shell fragments remaining on the shrimp.","url":"https://doi.org/10.20965/jrm.2026.p0764","authors":["Tomomi Murata","Kazuhiro Shimonomura"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-06-19T15:02:07Z","doi":"10.20965/jrm.2026.p0764","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/sii64115.2026.11404640","name":"Transformer-Based Robust Tactile Object Recognition under Sensor Faults through Training, Adaptation, and Correction","source":"crossref","abstract":"","url":"https://doi.org/10.1109/sii64115.2026.11404640","authors":["Masanori Muroyama"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-02-27T20:47:13Z","doi":"10.1109/sii64115.2026.11404640","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1109/mems64181.2026.11419461","name":"Piezoelectric-Decoupled Pyroelectric Sensor for Robotic Tactile Sensing and Materials Classification","source":"crossref","abstract":"","url":"https://doi.org/10.1109/mems64181.2026.11419461","authors":["Yoobin Choi","Hang Gyeom Kim","Hoe Joon Kim"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-11T19:35:46Z","doi":"10.1109/mems64181.2026.11419461","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.1016/j.sna.2026.118277","name":"Multifunctional tactile sensor system for tactile recorder","source":"crossref","abstract":"","url":"https://doi.org/10.1016/j.sna.2026.118277","authors":["Jeonggyun Jang","Dong Su Kim","Min Kyung Sim","Min Soo Kang","Kwonsik Shin","Junghyup Lee","Hongki Kang","Hyuk-Jun Kwon","Jae Eun Jang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-23T15:27:05Z","doi":"10.1016/j.sna.2026.118277","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.33425/2639-9466.1044","name":"Auxetic Tactile Skin Sensor for Real-Time Detection and Localization of Human Motion Intention Recognition","source":"crossref","abstract":"The rapid advancement of intelligent materials and bio-inspired engineering has opened new frontiers in human-robot interaction (HRI), enabling robots to perceive, respond, and adapt to human touch in real time. In this context, auxetic materials—characterized by their negative Poisson’s ratio—have emerged as promising candidates for enhancing the tactile responsiveness and mechanical adaptability of robotic skins. Their unique property of lateral expansion under tensile strain, coupled with superior energy absorption and strain amplification capabilities, makes them ideal for high-sensitivity tactile interfaces. In this study, we introduce a real-time tactile detection and localization system tailored for human-robot interaction, built upon an auxetic sensor-embedded multilayer structure. Inspired by the hierarchical organization of biological tissues such as human skin, the proposed architecture integrates mechanical compliance with intelligent sensing. The multilayer system comprises a rotating square patterned auxetic framework that facilitates mechanical transformation, a distributed matrix of piezo-resistive sensors for capturing contact stimuli, and a low-power embedded signal processing module optimized for real-time operation. The auxetic structure serves not only as a mechanical interface but also as a strain-amplifying scaffold that enhances the detection sensitivity of the tactile layer. This synergy allows the system to accurately interpret tactile events—including pressure magnitude, contact location, and stimulus type—at high temporal and spatial resolutions. The real-time signal processing pipeline employs adaptive noise filtering, centroid-based localization algorithms, and convolutional neural networks (CNNs) to classify tactile interactions, even in the presence of dynamic and unpredictable user inputs. Experimental evaluations in HRI scenarios demonstrate that the system can detect tactile forces as low as 1 N, with a localization error below 2.5 mm and a latency under 15 ms. It exhibits consistent performance under repeated human touch interactions, confirming its robustness and durability in continuous-use applications. This platform is particularly suited for soft robotic systems, robotic prosthetics, and socially interactive service robots where tactile perception is essential for safe, responsive, and intuitive engagement with humans. By integrating auxetic mechanics with bio inspired sensor design, our work contributes a novel approach to achieving perceptual intelligence in robotic systems, bridging the gap between artificial tactile sensing and human-like touch perception.","url":"https://doi.org/10.33425/2639-9466.1044","authors":["Dongchan Lee"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-03-06T06:50:46Z","doi":"10.33425/2639-9466.1044","addedAt":"2026-08-31T06:34:55.464Z","updatedAt":"2026-08-31T06:34:55.464Z"},{"id":"doi:10.2139/ssrn.6585220","name":"Textured Interface Design of a P(VDF-TrFE)-based Tactile Sensor for Flexible Grippers","source":"crossref","abstract":"Accurate pressure sensing and early slip detection are essential for safe, non-destructive grasping in flexible grippers.

Current tactile sensing methods, however, often fall short in recognition accuracy and adaptability to dynamic, real-world scenarios that mirror human touch. This study presents a novel method for Braille digit recognition by integrating a three-row parallel fiber Bragg grating (FBG) tactile sensor array with a Genetic Algorithm-optimized Backpropagation Neural Network (GA-BP). The FBG sensing principle for Braille dot detection is first explained. The flexible encapsulation structure and grating parameters of the sensor are then designed and optimized through finite element simulation. Based on this design, a flexible FBG sensor array is fabricated, and an experimental setup for dynamic sliding recognition of Braille digits is established. Following sensor calibration, sliding recognition experiments are conducted on ten Braille digit samples (0-9) to collect tactile signals. A standard Backpropagation Neural Network (BPNN) is initially employed for signal classification. To enhance performance, a GA-BP neural network is subsequently implemented and evaluated for the same task. Experimental results indicate that the fabricated sensor achieves a high average sensitivity of 71.30 pm/N with excellent linearity (&gt;0.996). In Braille digit classification, the GA-BP network attains an accuracy of 98.57%, outperforming the traditional BPNN (97.14%).

Traditional visual assessment relies on colour changes that may not be visible in richly pigmented skin, contributing to delayed diagnosis and poorer outcomes. Objective: Our aim was to identify and map strategies reported in the literature for assessing skin and underlying tissue to support early pressure injury detection in adults with dark skin tones in acute care settings. Methods: A scoping review was conducted following Joanna Briggs Institute methodology and reported according to PRISMA-ScR. Searches were performed in CINAHL, PubMed, Scopus, Web of Science, and Google Scholar (April 2025; updated February 2026). Primary research published in English since 2017 was eligible. After screening and data extraction, descriptive thematic analysis was applied to identify recurrent strategies reported in the literature for assessment of skin and underlying tissues for detection of pressure injury. No appraisal of the included sources was conducted. Results: Ten studies met the inclusion criteria. Strategies identified for detecting pressure injuries were mainly for implementation across diverse skin tones, but all included aspects of dark-skin-tone participants. These approaches are clustered into four categories: thermographic imaging, subepidermal moisture sensors, image processing and colorimetry, and enhanced assessment and lighting techniques. The evidence highlights the growing value of objective, technology-supported methods for improving detection in people with dark skin tones. Routine bedside visual and tactile assessment was notably underrepresented, indicating a clear evidence gap. Overall, the review emphasises the need to integrate objective technologies into everyday practice to support more equitable pressure injury detection. Conclusions: This scoping review highlighted that evidence for routine visual and tactile assessment in dark skin tones remains limited. Technology-supported assessment approaches show promise for improving diagnostic equity in pressure injury detection. Identification of strategies used to perform skin assessment for pressure injury identification is critical to the wellbeing of persons with dark skin tones. This review demonstrates that while emerging technologies offer promising ways to improve pressure injury detection across diverse skin tones, evidence supporting everyday bedside visual and tactile assessment for individuals with dark skin tones remains notably limited. Strengthening this evidence base and integrating objective technologies into routine care are essential steps toward more accurate and equitable pressure injury detection.","url":"https://pubmed.ncbi.nlm.nih.gov/42651424/","authors":["Mbuzi VB","Morgan S","Stratton-Maher D","Tulleners T","East L"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Aug 21","doi":"10.3390/healthcare14162655","addedAt":"2026-08-31T06:34:55.465Z","updatedAt":"2026-08-31T06:34:55.465Z"},{"id":"pmid:42634626","name":"Aerial tactile perching via an anthropomorphic hand with embodied soft tactile receptors.","source":"pubmed","abstract":"Aerial robots are widely employed for exploration, inspection, and environmental monitoring, where their agility and maneuverability are strong assets.

Over the years, several approaches have been developed to investigate tumor mechanobiology, however, existing techniques to quantify mechanical forces remain invasive and rely on indirect estimations of mechanical stress through mathematical modeling and entailing several assumptions. To address these challenges, we introduced a non-invasive method for in vivo measurement of macroscopic mechanical forces in solid tumors and the surrounding normal tissue. The proposed approach relies on a multi-sensor tactile imaging system based on fiber Bragg grating sensors (FBGs) to measure tumor forces and reconstruct 2D spatial force distributions. Unlike existing methods, this technique does not require the use of mathematical modeling, providing a clinically translatable framework for longitudinal monitoring of tumor mechanics. The method was applied to orthotopic 4T1 and E0771 murine breast tumor models at four time points during progression. The results demonstrated the capability of this technique to quantify the magnitude of forces in both tumor and surrounding normal tissue, allowing the reconstruction of spatial distributions that reflect the heterogeneous mechanical responses across the investigated area. Higher force levels were detected at tumor sites, and their temporal evolution was correlated with tumor volume and stiffness. The corresponding stress values were consistent with previous computational predictions, providing in vivo evidence of solid-stress accumulation in growing tumors. Overall, this study offers a complementary and directly translated to humans' strategy, expanding the experimental tools available for investigating tumor mechanics.

The cow-technical system behavior traits comprised visiting frequency in the milking robot (MILK-VIS), successful milkings (MILK-FREQ), AMS efficiency (MILK-EFF) reflecting milk yield per total box time and incomplete milkings (MILK-INCOMP), complemented with sensor behavior traits for rumination (RUM-TIME) and feeding duration (FEED-TIME). Production traits were daily milk yield (MY), fat percentage (Fat%) and protein percentage (Prot%) directly generated in the milking robot. Linear mixed models were applied to infer the impact of classical fixed effects of AMS-herd, season, parity and DIM on all behavior traits, indicating significantly lower least squares means for AVOIDIS in early parities and more problematic RELBH during summer. Genetic parameters were estimated by applying single-trait and multiple-trait repeatability models using a single-step approach simultaneously integrating pedigree and genomic 50K SNP data. Heritabilities for behavior traits from the cow-human and cow-technical system categories were low to moderate (0.03 to 0.35), indicating the potential for genetic improvement, especially for MILK-EFF (0.35 &#xb1; 0.031), FEED-TIME (0.30 &#xb1; 0.083) and RUM-TIME (0.26 &#xb1; 0.040). For cow-cow interaction traits, the heritability was 0.16 &#xb1; 0.031 for ACT, but close to zero for RECEIP. Phenotypic correlations among behavior traits were smaller than the respective genetic correlations. Strongest correlations were found between traits for the same behavior recorded in very dense intervals (e.g., genetic correlation of 0.81 &#xb1; 0.128 between avoidance distances at the same recording date), indicating consistency over repeated measurements. Across behavioral categories, genetic correlations were generally low to moderate, ranging from -0.26 &#xb1; 0.116 (RELBH with MILK-INCOMP) to 0.57 &#xb1; 0.125 (second TTI observation at the recording date with MILK-INCOMP). Based on their moderate heritabilities and mostly neutral genetic relationships with production traits, the cow-human interaction traits RELBH and TTI, and MILK-EFF from the cow-technical system behavior category, were identified as the most promising candidates for inclusion in AMS-specific breeding indices. In the present study, we estimated a broad portfolio of genetic covariances among cow behavior patterns from different behavior categories and with production traits, but for the construction of overall net merit indexes, genetic correlations with all other functional traits are imperative.","url":"https://pubmed.ncbi.nlm.nih.gov/42508486/","authors":["Behren LE","Vanvanhossou SFU","Breitmeier L","Stuhlträger J","Gieseke D","Rosner F","Swalve HH","König S"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jul 27","doi":"10.3168/jds.2026-28711","addedAt":"2026-08-31T06:34:55.465Z","updatedAt":"2026-08-31T06:34:55.465Z"},{"id":"pmid:42478794","name":"Microstructure-engineered flexible tactile sensors for bioelectronics and human-machine interactions: a review.","source":"pubmed","abstract":"Flexible tactile sensors, distinguished by their mechanical compliance and skin-like characteristics, have emerged as highly promising platforms for applications in bioelectronics and human-machine interactions.

A forearm-mounted six-actuator feedback system, encoding eight lower-limb configurations, was used in two experiments with healthy adults. Experiment 1 assessed recognition accuracy across ISIs from 10 to 110 ms, while Experiment 2 compared sinusoidal and square waveforms under matched conditions. Recognition accuracy was high across all tested conditions, with no significant effects of ISI ( p = 0.79) or waveform type ( p = 0.17). These results indicate that participants were able to interpret spatially distributed vibrotactile patterns even under rapid temporal sequencing and with differing signal shapes. The system therefore offers design flexibility for real-time prosthetic feedback, suggesting that fast update rates may be achievable without a statistically detectable reduction in perceptual clarity within the tested conditions. These findings provide practical guidance for developing robust, user-friendly sensory substitution systems intended to increase proprioceptive awareness in transfemoral prosthesis users.","url":"https://pubmed.ncbi.nlm.nih.gov/42122386/","authors":["Karimi M","Briem K","Kristjánsson Á","Brynjólfsson S","Unnthorsson R"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Apr 25","doi":"10.3390/s26092664","addedAt":"2026-08-31T06:34:55.466Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"pmid:42122319","name":"Haptic Feedback Reduces Telesurgery Operators' Reaction Times Compared to Conventional Stimulation: Results of a First-in-Human Study.","source":"pubmed","abstract":"This prospective, cross-sectional study evaluated reaction time (RT) variations across different sensory stimuli to investigate the efficacy of haptic feedback (HF) in reducing response latency for telesurgical applications.

The synergistic effect of both the piezoelectric effect and field effect further endowed the devices with effective perception of both static and dynamic mechanical excitation beyond the capability of a piezoelectric capacitor alone. Such devices realized proximity perception of a variety of common objects and tactile perception of pulse, breath, and bending of human joints.

However, current assessments often struggle to evaluate the hand's ability to precisely control grip force, a skill vital for daily activities like handling fragile objects. Here we describe the design of the Electronic Grip Gauge (EGG), an adjustable-weight, instrumented \"fragile\" object that measures grip force, load force, acceleration, orientation, and relative position. Embedded sensors enable automatic segmentation and analysis of EGG transfers in various modes. In \"Non-Fragile\" mode, there is no break threshold; the EGG serves as an automated variant of the Box-and-Blocks test. In \"Fragile\" mode, the EGG simulates fragility by playing a \"break\" noise if grip force exceeds a set threshold, requiring grip control to prevent breaks. In \"Fragile-Feedback\" mode, audio-visual feedback is provided proportional to applied grip force to supplement potentially impaired tactile feedback. Demonstrating functionality, we evaluated sensorimotor differences between 26 hemiparetic and 26 age-matched healthy participants. In \"Fragile\" mode, paretic hands were significantly slower, applied excessive force, and broke the EGG more frequently than contralateral and healthy control hands. In \"Fragile-Feedback\" mode, a subset of paretic hands improved, transferring the EGG faster and/or with less force. This work demonstrates the EGG's utility in automatically quantifying sensorimotor deficits and that, for a subset of hemiparetic patients, audiovisual feedback could potentially coach and rehabilitate hand function.

Previous studies have showed that corrective actions occur after tactile afferents signal surface friction or slip events. However, the influence of the mechanical behavior of the skin on the development of contact forces is poorly understood. In this study, using contact kinematics derived from a natural reach-and-grasp task, we applied a glass surface onto restrained fingers via a robotic manipulator under low- and high-friction conditions. Contact forces were measured with a force sensor, and skin deformations were captured using a high-speed camera. As expected, the normal force remained unaffected by friction, however, interestingly the tangential force rose more slowly and peaked lower under low friction. This resulted in a higher normal-to-tangential force ratio, resembling friction-dependent scaling of grip-to-load force ratio observed in active grasping. The skin partially slipped throughout contact development, with the proportion of the slipped area first decreasing and then increasing. The time course of tangential force correlated with the extent of skin slip, both varying with friction. The findings demonstrate that skin mechanics potentially influences the grip stabilization during the initial phase of object handling, which doesn't involve feedback-driven grip force adjustments.","url":"https://pubmed.ncbi.nlm.nih.gov/41766029/","authors":["Devecioğlu İ","Ruhi R","Afzal N","Loutit AJ","So A","Wiertlewski M","Vickery RM","Birznieks I"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Mar 1","doi":"10.1038/s41598-026-41781-z","addedAt":"2026-08-31T06:34:55.466Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"pmid:41761840","name":"Seconds-Integrated Monolithic System of Zn-Ion Micro-Battery and Multi-Functional Sensors for Robotic Autonomous Tactile Sensing.","source":"pubmed","abstract":"Highly integrated devices that combine energy storage with multi-functional sensing capabilities are pivotal for advancing the practical implementation of intelligent microsystems.

This study investigates the feasibility of recognizing natural QWERTY typing motions directly at the word level using only a single RGB camera, under a fixed single-user and single-camera configuration. We propose a word-level contactless typing framework that models each word as a distinctive spatiotemporal finger motion pattern derived from hand joint trajectories. Typing motions are temporally segmented, and direction-aware finger displacements are accumulated to construct compact motion representations that are relatively insensitive to absolute hand position and typing duration within the evaluated setup. Each word is represented by multiple motion prototypes that are incrementally updated through online learning with a trial-delayed adaptation protocol. Experiments with vocabularies of up to 200 words show that the proposed approach progressively learns and recalls word-level motion patterns through repeated interaction, achieving stable recognition performance within the tested configuration at realistic typing speeds. Additional evaluations demonstrate that learned motion representations can transfer from physical keyboards to flat-surface typing within the same experimental setting, even when tactile feedback and visual layout cues are reduced. These results support the feasibility of reframing contactless typing as a word-level motion recall problem, and suggest its potential role as a complementary component to character-centric camera-based input methods under constrained monocular sensing.","url":"https://pubmed.ncbi.nlm.nih.gov/41755025/","authors":["Yoo SS","Lee HS"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Feb 7","doi":"10.3390/s26041087","addedAt":"2026-08-31T06:34:55.466Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"pmid:41737105","name":"Robots at the Chairside: A Narrative Review of Robotic-Assisted Surgery Revolutionizing Dental Implantology in the Digital Dentistry Era.","source":"pubmed","abstract":"The advent of robotic-assisted technologies has introduced a paradigm shift in dental implantology, aiming to enhance surgical precision, safety, and predictability. Robotic implant surgery integrates advanced imaging, computer-aided planning, and mechanized execution to overcome the inherent limitations of conventional freehand and static/dynamic navigation techniques. Traditional implant placement is heavily dependent on clinician experience, tactile feedback, and intraoperative judgment, which may result in deviations in implant positioning, prosthetic misalignment, or damage to vital structures. Robotic systems, such as Yomi (Neocis, Miami, FL, USA), Remebot (Beijing Baihui Weikang Technology Co., Ltd., Beijing, China), and Yakebot (Beijing Yakebot Technology Co., Ltd., Beijing, China), utilize haptic, visual, and combined feedback mechanisms to guide implant osteotomy and placement, thereby reducing human error, hand tremors, and operator fatigue. Robotic platforms employ either semi-active or fully autonomous modalities, each offering distinct levels of surgical autonomy while maintaining surgeon oversight. Semi-active systems provide positional constraints and guidance, allowing surgeons to control drill motion within pre-planned trajectories, whereas active systems can execute osteotomies and implant insertion autonomously under real-time monitoring. These systems leverage three-dimensional imaging, cone-beam computed tomography (CBCT), optical markers, and force/torque sensors to achieve sub-millimetric accuracy in implant positioning. Furthermore, integration of artificial intelligence and machine learning algorithms enables adaptive responses to patient movement, variations in bone density, and thermal monitoring, simulating the tactile perception of experienced surgeons. Beyond accuracy, robotic systems offer advantages in minimally invasive surgery, including reduced tissue trauma, improved flapless approaches, decreased surgical time in experienced hands, and enhanced ergonomics for clinicians. Moreover, robotic platforms hold potential for complex procedures such as full-arch rehabilitation and zygomatic implant placement, where conventional techniques pose greater risk. In conclusion, robotic-assisted dental implantology represents a transformative advancement, combining technological innovation with surgical precision to enhance clinical outcomes. Continued development and rigorous clinical evaluation are imperative to maximize its utility, broaden accessibility, and facilitate the transition from experimental to standard practice in contemporary implant dentistry.","url":"https://pubmed.ncbi.nlm.nih.gov/41737105/","authors":["Vinodkumar V","Menon SS","Bharathkrishnan M","Kurumathur Vasudevan A","Balakrishnan B","Rajan Peter M","Suresh R"],"tags":[],"confidence":0.82,"sites":["robot-parts"],"publishedDate":"2026 Jan","doi":"10.7759/cureus.102185","addedAt":"2026-08-31T06:34:55.466Z","updatedAt":"2026-08-31T06:34:55.466Z"},{"id":"pmid:41716647","name":"Fabric topological haptic proxy for interactive virtual reality.","source":"pubmed","abstract":"Physical objects serving as haptic proxies offer a promising approach to enrich tactile experience in virtual reality.

The tactile sensing array measures distributed pressures across the palm and dorsum to enable real-time estimation of compression rate, force, and hand pose.

A common approach to track gloved hands is to directly use the sensor signals (e.g., angular velocity, gravity orientation) to estimate 3D hand poses. However, sensor-based tracking can be restrictive in practice as the accuracy is often impacted by sensor signal and calibration quality. Recent advances in vision-based approaches have achieved strong performance on human hands via large-scale pre-training, but their performance on gloved hands with distinct visual appearances remains underexplored. In this work, we present the first systematic evaluation of vision-based hand tracking models on gloved hands under both zero-shot and fine-tuning setups. Our analysis shows that existing bare-hand models suffer from substantial performance degradation on sensing gloves due to large appearance gap between bare-hand and glove designs.

EEG is a novel method for electrotactile analysis and has demonstrated the discrimination ability for electrotactile sensation under steady contact conditions in recent years. However, in non-steady contact conditions, it is necessary to test its effectiveness. This study aims to explore an objective analysis method in comparison to psychophysical approach and to provide a methodology for non-steady electrotactile research. Design/methodology/approach With EEG experimentation on 13 volunteers, the authors collected evoked potentials by the predesigned “1” and “0” stimulation events. In addition, with a series of data preprocessing including artifact elimination, band-pass filtering, baseline normalization, data superposition and fast Fourier transform transformation, the authors got the power spectrum of alpha, beta and gamma rhythms. Furthermore, statistics analysis and ANOVA test were adopted for exploring the discrepancy of the spectrum characterizations for different non-steady electrostimulation events. Findings The EEG power spectrum of the central cortical brain is valuable in discriminating the two types of stimulation events. The power of alpha rhythm especially in the central cortical brain evoked by event “1,” whose current level is equal to the threshold, was significantly lower than that evoked by event “0,” whose level is less than the threshold ( p &lt; 0.05). Then, the power of the beta rhythm presented counter-change ( p &lt; 0.05). This study suggests that EEG may have the potential to qualify non-steady electrotactile sensation for engineering applications.

The approach is validated by reconstructing unsheared tactile images from sheared images and showing they match unsheared tactile images collected with no sliding motion. In addition, the unsheared tactile images give a faithful reconstruction of the contact geometry that is not possible from the sheared data, and robust estimation of the contact pose that can be used for servo control sliding around various 2D shapes. Finally, the contact geometry reconstruction in conjunction with servo control sliding were used for faithful full object reconstruction of various 2D shapes.

For robots, tactile sensing is also irreplaceable. While interacting with objects, tactile sensing provides useful information for the robot to understand the object, such as distributed pressure, temperature, vibrations and texture. During robot grasping, vision is often occluded by its end-effectors, whereas tactile sensing can measure areas that are not accessible by vision. In the past decades, a number of tactile sensors have been developed for robots and used for different robotic tasks. In this chapter, we focus on the use of tactile sensing for robotic grasping and investigate the recent trends in tactile perception of object properties. We first discuss works on tactile perception of three important object properties in grasping, i.e., shape, pose and material properties. We then review the recent development in grasping stability prediction with tactile sensing. Among these works, we identify the requirement for coordinating vision and tactile sensing in the robotic grasping. To demonstrate the use of tactile sensing to improve the visual perception, our recent development of vision-guided tactile perception for crack reconstruction is presented. In the proposed framework, the large receptive field of camera vision is first leveraged to achieve a quick search of candidate regions containing cracks, a high-resolution optical tactile sensor is then used to examine these candidate regions and reconstruct a refined crack shape. The experiments show that our proposed method can achieve a significant reduction of mean distance error from 0.82 mm to 0.24 mm for crack reconstruction. Finally, we conclude this chapter with a discussion of open issues and future directions for applying tactile sensing in robotic tasks.","url":"https://doi.org/10.48550/arxiv.2112.14119","authors":["Jiang, Jiaqi","Luo, Shan"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.48550/arxiv.2112.14119","addedAt":"2026-08-31T06:34:55.558Z","updatedAt":"2026-08-31T06:34:55.558Z"},{"id":"doi:10.7488/era/944","name":"Compliant Piezoresistive e-Skin for force and location sensing","source":"datacite","abstract":"Electronic skin (e-skin) is an emerging field with an increasing number of applications such as biomedical, wearables sports and health monitoring, virtual and augmented reality. Less obvious use-cases can also be found in smart tyres for self-driving cars, structural integrity monitoring, and environmental pressure mapping. The e-skin market is growing at a fast pace, with a CAGR of 38.7% from its current worth of around ~$500 million. To date, it has been impossible to integrate the variety and density of mechanoreceptors found in human skin in a compliant form-factor with a similar Young’s modulus and other mechanical properties. Recent developments that attempt to combine non-tactile sensory inputs (e.g. temperature, humidity) with tactile ones sacrifice tactile feedback. A domain that has been labelled a grand challenge is that of robotic dextrous manipulation. Indeed, the attempt to input tactile data into machines is the birthplace of e-skin. No better is the challenge illustrated than with the evolutionary marvel of the human hand, and how our nervous system and brain use real-time feedback, control, and actuation to manipulate the world around us. Tactile inputs are force inputs. Thus, measuring force is chosen as the focus of this dissertation, which aims to tackle challenges in making e-skin ubiquitous, with a focus on robotics applications. The first two parts of this dissertation review the various sensing modalities which can be used to measure forces in e-skin, including capacitive, piezoresistive, electromagnetic induction, magnetic field detection, optical, piezoelectric, and triboelectric. Their respective strengths, weaknesses, and complementarity are weighed to justify the selection of the piezoresistive modality for static and low-frequency sensing. Furthermore, a broad literature review is given on piezoresistive sensing methods with a focus on traditional strain gauges and piezoresistors, liquid metal, percolation dominated polymer composites, tortuous strain gauges, crack-enhanced strain gauges, contact-resistance based sensors, and quantum tunnelling dominated polymer composites. These are also weighed with specific focus on their potential for compliance, mass-production, and repeatability to select two which are studied in more detail. The third part goes through the various characterisation tools and techniques used in this thesis. The fourth part of the dissertation addresses sensitivity, stretchability, robustness, and mass-producibility of a flexible thin film strain gauge sensor on a PDMS substrate. Attention is paid to selecting gold as the metal with the best properties by observing its behaviour under tensile strain. Controlling metal deposition thickness using sputtering leads to out-of-plane buckling causing wrinkles to form, which enables minor stretching. This in addition to a thin spin-coated substrate and surface-modified PDMS adhesion layer, yield a highly sensitive and compliant strain gauge that can be wrapped around most surfaces, the sensitivity of which can be increased by inducing microcracks in the metal layer. The use of shadow masks enables mass-production of strain gauges with 100% yield. However, an attempt to use diaphragm strain gauges in robotics applications fails due to hysteresis, creep, and fragility of the sensors. Subsequent electromechanical characterization reveals that although the gauge factor is high at ~1447, the stretchability of the substrate is only ~0.74%, causing catastrophic failure due to crack propagation at low strains. The three following parts of this thesis focus on the design and fabrication of an e-skin system by screen printing a novel magnetite micro-particle based quantum tunnelling material. It describes the design process for a glove made from the e-skin, which itself is produced using the tunnelling ink as well as other composite inks containing conductive fillers.

Unlocking new application scenarios requires changing the intrinsic properties of these sensors to make them adaptable to new challenges. One way to accomplish this goal, is to allow these sensors to change shape and be flexible, stretchable or solution-processable, what we call shapeable magnetoelectronics [1]. This technology relies on the smart combination of inorganic thin films prepared directly on flexible or elastomeric substrates. Shapeable magnetoelectronics resulted from the cooperative effort of fundamental and application-oriented communities in the field of curvilinear magnetism [2], and the involvement of fabrication methods for flexible electronics [3], [4]. The combination of these research fields has resulted in a variety of flexible [5], [6], printable [7]–[9], stretchable [10]–[12] and imperceptible17,35–37 magnetic field sensing elements. Stemming from these developments, various applications like automotive [19], consumer electronics and point of care [6], [13], [14], and virtual reality [15]–[17], have emerged. For automotive purposes, shapeable magnetic sensors can be useful to monitor the magnetic field profile the nonplanar and narrow gaps inside electrical motors, to minimize losses and improve the overall efficiency [5]. In point-of-care applications, they can enable fast biosensing methods for wearable health monitoring based on magnetofluidics [6], [13]. For virtual reality they allow a whole new set of touchless interaction possibilities using the ambient magnetic fields as input stimuli [15]–[17]. One example of this application is an on-skin sensor, which can dim the intensity of a virtual lightbulb based on the relative angle between the sensor and the magnetic field of a permanent magnet [16]. This idea was further improved to remove the need for permanent magnets and instead use the earth’s magnetic field as input stimulus. Reaching this level of sensitivity required the use of barber pole [18] modified anisotropic magnetoresistive (AMR) sensors, which allowed detecting magnetic fields of µT with a flexible on-skin patch. Aside from enable artificial magnetoception, the patch can be used as an interactive device for virtual reality which only uses the geomagnetic field 15 (Fig. 1). Further works have improved the sensitivity to about 200 nT, which could have applications for highly sensitive point-of-care devices [14]. In recent works, we have demonstrated shapeable magnetoelectronics which are multimodal, so that they transduce and discriminate both tactile (via mechanical pressure) and touchless (via magnetic field) stimuli in real time [17]. Such a feat is attained by fabricating a magnetic microelectromechanical platform (m-MEMS), which combines flexible magnets based on polymer composites and mechanically compliant magnetic sensors. These m-MEMS e-skins enable complex interactions with magnetically functionalized objects in the real world, which supplement the content data appearing in virtual reality. For example, an augmented reality menu with multiple layers of interaction can be operated with one single sensor using its embedded multidimensional touch (Fig. 2, top). A challenging aspect for shapeable magnetoelectronics is the fact that output signals are usually amplified by rigid components outside the flexible supports. This readout scheme can introduce substantial noise through the cabling which is then amplified together with the signals. Eliminating this noise requires including amplifying elements directly on the flexible support, which implies using intrinsically flexible, thin-film transistor technologies. We have demonstrated such an approach, by combining highly sensitive magnetic field sensorics with high performance InGaZnO based readout electronics, on the same flexible support 19 (Fig. 2, bottom).

We apply long-wave approximation to theoretically calculate the required distribution of pneumatic network and inlet pressure oscillations needed to create desired moving wave patterns. We then fabricate soft robots with internal pneumatic network geometry based on these analytical results.

This article proposes a rapid, efficient framework for determining where to place the sensors on the system given the limited number of available sensors. In particular, given m candidates in location for sensor placement, the algorithm recommends m 0 locations that guarantee the maximal estimation performance, based on Bayesian sampling. The sampling and optimization method aims to maximize the log-likelihood in nonparametric regression between the measured values of the selected sensors and the target references. The proposed approach for the optimal sensor placement is validated through two scenarios: full-body motion sensing with a soft wearable sensor suit and fingertip position tracking with a motion-capture system. The proposed algorithm successfully determines the sensor locations close to the optimum within 20 min of learning for both cases.","url":"https://doi.org/10.1089/soro.2024.0044","authors":["DongWook Kim","Seunghoon Kang","Yong-Lae Park"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-12-24T12:25:53Z","doi":"10.1089/soro.2024.0044","addedAt":"2026-08-31T06:34:56.054Z","updatedAt":"2026-08-31T06:34:56.054Z"},{"id":"doi:10.1089/soro.2018.0169","name":"Designing Fiber-Reinforced Soft Actuators for Planar Curvilinear Shape Matching","source":"crossref","abstract":"Fiber-reinforced soft pneumatic actuators can generate a wide variety of deformation behavior, making them popular in the field of soft robotics. Designing an actuator to meet a specified deformed shape is an important step toward the design of soft robots. We present a two-step methodology to design an actuator that matches a given planar curve on pressurization. In the first step, the curve is divided into a series of constant curvature (CC) segments that best approximate its shape. The second step involves designing a bending actuator by determining its fiber orientations for each CC segment. Further, this two-step method is extended to match two curves: a final deformed curve and an intermediate curve at a lower actuation pressure. On combining all the CC segments, the resulting actuator lies along a straight line unpressurized, and on pressurization deforms to trace the desired final curve through a preset intermediate curve. To demonstrate the method, we show different examples: an omega curve for an inchworm robot, an acronym SoRo for the Soft Robotics Journal, and a two-stage bending actuator.","url":"https://doi.org/10.1089/soro.2018.0169","authors":["Gaurav Singh","Girish Krishnan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2019-09-30T18:58:01Z","doi":"10.1089/soro.2018.0169","addedAt":"2026-08-31T06:34:56.054Z","updatedAt":"2026-08-31T06:34:56.054Z"},{"id":"doi:10.1089/soro.2020.0142","name":"Nanotextured Soft Electrothermo-Pneumatic Actuator for Constructing Lightweight, Integrated, and Untethered Soft Robotics","source":"europepmc","abstract":"In this study, we fabricated a nanofiber-based electrothermo-pneumatic soft actuator (ETPSA) using electrospinning technique.

These systems comprise soft and flexible materials to achieve high degrees of freedom and compliance with their surroundings. One method to actuate such structures is to vaporize liquid that is embedded inside the soft material. The soft elastomers are inflated since the generated vapor occupies a much larger volume after phase transformation. The simplest and widely used design to vaporize such liquids is installing a heating element near the liquid. Heating the system beyond the boiling point rapidly boils the liquid and deforms the structure. However, this technique possesses several limitations, such as the heating element must be in the liquid's vicinity, and boiling the liquid requires high temperatures. In addition, embedding a small amount of liquid for faster boiling prevents the use of valves to exhaust the vapor. Instead, the structure is slowly cooled until it returns to its original position. In this study, these limitations are addressed by combining heating with vibrating mesh atomization. The atomizer disperses the liquid into small droplets, which vaporize much faster as compared with simply heating the bulk liquid. Actuation through vibrating mesh atomization was first characterized and compared with other techniques. Then, the introduced method was used to demonstrate cyclic actuation, and a bistable structure was designed and fabricated to demonstrate gripping motion.","url":"https://doi.org/10.1089/soro.2020.0055","authors":["Han-Joo Lee","Peerasait Prachaseree","Kenneth J.

The trajectory of the helical actuator was analyzed through the finite element method (FEM) by changing the angle of the chambers and the actuator length.

Self-sensing typically involves embedding a conductive sensing element into the soft actuator and provides multiple state information along the continuum. However, most of these self-sensing actuators are fabricated through manual methods, which results in inconsistent sensing performance. Soft material compliance also imply that both actuator and sensor exhibit nonlinear behaviors during actuation, making sensing more complex.

In this work, we aim to improve the reliability of soft robots by modeling and characterizing the performance of SPAs with widely used chamber shapes and cross-sectional geometries under variable loading conditions. We also compare their capacity to provide homogeneous, repeatable, and time-wise consistent expansion with low-stress concentrations and provide a set of principles for the design of reliable SPAs. Expansion of SPAs with Straight chambers demonstrated to be more repeatable, with an average deviation of 0.06 mm and showed more than a thousand times less stress than any other chamber types. The expansion of preshaped SPAs with helical chambers showed to be up to 500% more homogeneous and 300% more efficient than their deflected counterparts. SPAs with squared cross-sectional geometries displayed more than 1000 times more time-wise consistent expansion over their circular counterparts. We conclude that SPAs that retain less potential energy or are less affected by its effects are more reliable. We derive these results into a set of principles for the design of reliable SPAs.

However, the same compliance hinders the generation of propelling forces, and current approaches face a trade-off between traveling speed, action range, and control complexity. We overcome this trade-off by developing a locomotion mechanism based on the synergistic interaction between symmetric vibrations, elasticity, and asymmetric morphology. We then realize a rapid soft locomotor using inexpensive off-the-shelf components and requiring only elementary actuation and control. A single robotic unit can travel at speeds up to 100 mm/s when tethered and 35 mm/s when untethered. We derive a model that predicts the speed of the robot as a function of several design parameters and physical properties, highlighting the role of geometric asymmetries in the resulting anisotropic motion.

The morphology is designed into a compact tuning fork shape (130 × 110 × 260 mm, 389 g) with two bidirectional sheet-shaped soft fingers and a biaxial bidirectional (universal) cylinder-shaped soft wrist. The multi-degree of freedom of soft fingers and wrist makes the gripper versatile and adaptable to gripping objects of various shapes, sizes, and orientations in a wide range. The bidirectional fingers with double-side inflatable chambers can tune their gripping stiffness and force by varying the common and differential pressure of the two sides. The wrist can tune its deflecting stiffness and force in the same way. Therefore, the gripper can grip objects of various stiffness and weights. The soft gripper is tested to characterize its workspace, stiffness, gripping force, and dynamic response time. Gripping function tests are also performed to evaluate the achieved degree of functions of the gripper. Tests show that the proposed gripper can grip objects in the size of 0–245 mm and in the orientation of −88.2°–90.8° (pitch/roll) with a maximum gripping force of 40 N and a response time of 1.22–1.60 s to force and 0.56–2.61 s to motion, respectively. The gripping stiffness can be tuned in the range of 0.029–0.137 N/mm (i.e., the tunable scope is 79%) by varying common pressure in the range of 0–0.2 MPa. Functional tests verify that the proposed soft gripper is versatile and adaptable to gripping objects of various shapes, sizes, weights, and orientations. Therefore, the proposed soft gripper has great potential applications in production and daily life.","url":"https://doi.org/10.1089/soro.2018.0015","authors":["Yanqiong Fei","Jiangbei Wang","Wu Pang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-10-12T13:57:36Z","doi":"10.1089/soro.2018.0015","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1201/9781003539612-12","name":"Designing bio-inspired soft robotics for medical applications","source":"crossref","abstract":"","url":"https://doi.org/10.1201/9781003539612-12","authors":["K M Vinay","M Prasanna Kumar"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-04-09T21:33:58Z","doi":"10.1201/9781003539612-12","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2022.0111","name":"A Skin-Like Soft Compression Sensor for Robotic Applications","source":"crossref","abstract":"We present a compression sensor based on a strain-sensitive carbon black–silicone composite cast on top of a printed circuit board with interdigitated electrodes.

In this study, the actuator is constructed using gallium indium liquid metal conductors, compliant permanent magnetic composites, carbon black powders, and flexible polymers. The actuator also operates using low voltages (&lt;20 V, ≤10 A), has a bandwidth of 10 Hz, a stall torque of 2.5–3 mN·m, and no-load speed of up to 4000 rpm. These values show that the actuator rotates at over two orders-of-magnitude higher speed with at least one order-of-magnitude higher output power than previously developed soft rotary actuators. This unique soft rotary motor is operated in a manner similar to traditional hard motors, but is also able to stretch and deform to enable new soft robot functions. To demonstrate fully-soft actuator application concepts, the motor is incorporated into a fully-soft air blower, fully-soft underwater propulsion system, fully-soft water pump, and squeeze-based sensor for a fully-soft fan. Hybrid hard and soft applications were also tested, including a geared robotic car, pneumatic actuator, and hydraulic pump.

In this study, we propose a novel artificial soft whisker sensor that is not only flexible but also adapts and compensates for being trimmed or broken during operation. In this morphological compensation designed from an analytical model of the whisker, our sensing device actively adjusts its morphology to regain sensitivity close to that of its original form (before being broken). To serve this purpose, the body of the whisker comprises a silicon-rubber truncated cone with an air chamber inside as the medulla layer, which is inflated to achieve rigidity. A small strain gauge is attached to the outer wall of the chamber for recording strain variation upon contact of the whisker. The chamber wall is reinforced by two inextensible nylon fibers wound around it to ensure that morphology change occurs only in the measuring direction of the strain gauge by compressing or releasing pressurized air contained in the chamber. We investigated an analytical model for the regulation of whisker sensitivity by changing the chamber morphology. Experimental results showed good agreement with the numerical results of performance by an intact whisker in normal mode, as well as in compensation mode. Finally, adaptive functionality was tested in two separate scenarios for thorough evaluation: (1) A short whisker (65 mm) compensating for a longer one (70 mm), combined with a special case (self-compensation), and (2) vice versa . Preliminary results showed good feasibility of the idea and efficiency of the analytical model in the compensation process, in which the compensator in the typical scenario performed with 20.385% average compensation error. Implementation of the concept in the present study fulfills the concept of morphological computation in soft robotics and paves the way toward accomplishment of an active sensing system that overcomes a critical event (broken whisker) based on optimized morphological compensation.","url":"https://doi.org/10.1089/soro.2020.0056","authors":["Nhan Huu Nguyen","Van Anh Ho"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-01-19T16:51:47Z","doi":"10.1089/soro.2020.0056","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2017.0022","name":"Soft Dielectric Elastomer Oscillators Driving Bioinspired Robots","source":"crossref","abstract":"","url":"https://doi.org/10.1089/soro.2017.0022","authors":["E.-F.

By pulling or releasing the tendons, the air pressure in the soft actuator is modulated, and hence, its bending angle. The tendons serve in a way similar to pressure-regulating valves that are used in typical pneumatic systems. The linear motion of tendons is transduced into complex motion via the prepressurized bent soft actuator.

To support efficient underwater exploration, we designed, developed, and tested an aerially deployed underwater vehicle featuring a compact, lightweight soft gripper. This design reduces water disturbance and enables precise navigation in confined underwater environments, significantly expanding operational capabilities underwater. By analyzing the pod’s volume changes, buoyancy actuation, and propulsion mechanisms, we derive a simplified dynamic model to describe the underwater motion. We developed a control framework that decouples buoyancy, thrust, and yaw to enable independent control of underwater motion. Precise buoyancy control, essential for navigating interstices without causing ecological harm, was achieved with feedback control loops taking water depth as feedback, showing a rise time of under 5 s and a 10% settling time within 30 s. Yaw control, achieved via inertial measurement unit feedback, exhibited a rise time of less than 10 s with oscillations of 10%–25% around the set values.

However, such soft robots and actuators are tethered to a bulky pump and controlled by various valves, limiting their applications to a small confined space. In this study, we report a new and effective approach to fluidic power actuation that is untethered, easy to design, fabricate, control, and allows various modes of actuation. In the proposed approach, a sealed elastic tube filled with fluid (gas or liquid) is segmented by adaptors. When twisting a segment, two major effects could be observed: (1) the twisted segment exhibits a contraction force and (2) other segments inflate or deform according to their constraint patterns. Utilizing such effects, various actuation modes could be realized. In this research, four modes of actuation are illustrated: (1) soft actuator and pump actuation, (2) serial actuation, (3) parallel actuation, and (4) agonist and antagonist actuation. Theoretic analysis and experimental studies for the basic actuation principle have been conducted. A case study on an anthropomorphic forearm based on the proposed twisting tube actuation has been developed to showcase the effectiveness of the actuation modes.

In this article, we present an approach to the design of slender, high flexural stiffness modules based on the principle of fiber jamming . The proposed fiber jamming modules (FJMs) consist of axially packed fibers in an airtight envelope that transition from a flexible to a rigid beam when a vacuum is created inside the envelope. This FJM can provide the flexural stiffness of up to eight times that of a particle jamming module in the rigid state. Unlike layer jamming modules, the design of FJMs further allows them to control stiffness while bending in space.

A numerical description is needed to enable the understanding of key features of shape and how they change as the soft body deforms. It can also quantify similarity between shapes. In this article, we use a method based on elliptic Fourier descriptors to describe soft deformable morphologies. We perform eigenshape analysis on the descriptors to extract key features that change during the motion of soft robots, showing the first analysis of this type on dynamic systems. We apply the method to both biological and soft robotic systems, which include the movement of a passive tentacle, the crawling movement of two species of caterpillar ( Manduca sexta and Sphacelodes sp.), the motion of body segments in the M. sexta , and a comparison of the motion of a soft robot with that of a microorganism (euglenoid, Eutreptiella sp.). In the case of the tentacle, we show that the method captures differences in movement in varied media. In the caterpillars, the method illuminates a prominent feature of crawling, the extension of the terminal proleg.

In this study, we propose a new inflatable soft actuator driven by two spiral chambers twined with fibers for the first time. A key feature of this actuator is that it possesses a pure and high-efficient torsional motion with no bending and extension movements when works without load, which reduces the difficulties of theoretical analysis and control to some extent. Kinematic model is established by combining virtual work principle and elastic strain energy function for nonlinear flexible materials. The new soft torsional actuator module is carefully designed and fabricated, of which both the kinematic property and output torque are investigated experimentally. Results show that the module exhibits good linearity with air pressure ranging from 35 to 100 kPa, and can provide a torsion angle of up to 110° with an angular displacement accuracy of ±2° in empty loaded conditions; the maximum output torque reaches 0.026 N·m with the corresponding air pressure of 100 kPa. Finally, three soft robots are assembled by utilizing this new, inflatable, pure, soft torsional actuator, and successfully carry out different manipulating tasks.

These robots have the potential to be robust and versatile, even safer for human interaction compared to traditional rigid robots. Soft robots based on biomimetic principles are being designed for real life applications by paying attention to different shape, geometry, and actuation systems in these organisms that respond to surrounding environments and stimuli. Especially, caterpillars or inchworms have garnered attention due to their soft compliant structure and crawling locomotion system making them ideal for maneuvering in congested spaces as a transport function. Currently, there are two major challenges with design and fabrication of such soft robots: using an efficient actuation system and developing a simple manufacturing process. Different actuation systems have been explored, which include shape memory alloy based coils and hydraulic and pneumatic actuators. However, the intrinsic limitations due to overall size and control system of these actuators prevent their integration in flexibility, lightweight, and compact manner, limiting practical and untethered applications. In comparison, magnetic actuation demonstrates simple wireless noncontact control. In terms of manufacturing process, additive manufacturing has emerged as an effective tool for obtaining structural complexity with high resolution, accuracy, and desired geometry. This study proposes a fully three-dimensional (3D) printed, monolithic, and tetherless inchworm-inspired soft robot that uses magnetic actuation for linear locomotion and crawling.

This dimensional change alters the dynamics of locomotion and can assist them in maneuvering variable terrains. The sphere-plane reconfiguration is equivalent to projecting a spherical shell onto a plane, an operation that is not possible without distortions. Fortunately, soft materials have the potential to adapt to this disparity of the Gaussian curvatures. Modular Soft Robots (MSoRos) have promise of achieving dimensional change by exploiting their continuum and deformable nature. However, the design of such soft robots has remained unexplored thus far. Here, for the first time, we present the topology and morphology design of MSoRos that are capable of reconfiguring between spherical and planar configurations. Our approach is based in geometry, where a platonic solid determines the number of modules required for plane-to-sphere reconfiguration and the radius of the resulting sphere, for example, four “tetrahedron-based” or six “cube-based” MSoRos are required for spherical reconfiguration. The methodology involves: (1) inverse orthographic projection of a “module-topology curve” onto the circumscribing sphere to generate the spherical topology ; (2) azimuthal projection of the spherical topology onto a tangent plane at the center of the module resulting in the planar topology ; and (3) adjusting the limb stiffness and curling ability by manipulating the geometry of cavities to realize a physical finite-width, Motor-Tendon Actuated MSoRo that can actuate between the sphere-plane configurations. The topology design is shown to be scale invariant, that is, the scaling of base platonic solid is reflected linearly in spherical and planar topologies. The module-topology curve is optimized for the reconfiguration and locomotion ability using an intramodular distortion metric that quantifies sphere-to-plane distortion. The geometry of the cavity optimizes for the limb stiffness and curling ability without compromising the actuator's structural integrity.","url":"https://doi.org/10.1089/soro.2021.0125","authors":["Caitlin Freeman","Michael Maynard","Vishesh Vikas"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-07-07T10:48:30Z","doi":"10.1089/soro.2021.0125","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1016/c2018-0-04050-5","name":"Soft Robotics in Rehabilitation","source":"crossref","abstract":"","url":"https://doi.org/10.1016/c2018-0-04050-5","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-02-26T22:46:29Z","doi":"10.1016/c2018-0-04050-5","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2022.0070","name":"Kinetostatic Modeling of Soft Robots: Energy-Minimization Approach and 99-Line MATLAB Implementation","source":"crossref","abstract":"Soft robots have received a great deal of attention from both academia and industry due to their unprecedented adaptability in unstructured environment and extreme dexterity for complicated operations. Due to the strong coupling between the material nonlinearity due to hyperelasticity and the geometric nonlinearity due to large deflections, modeling of soft robots is highly dependent on commercial finite element software packages. An approach that is accurate and fast, and whose implementation is open to designers, is in great need. Considering that the constitutive relation of the hyperelastic materials is commonly expressed by its energy density function, we present an energy-based kinetostatic modeling approach in which the deflection of a soft robot is formulated as a minimization problem of its total potential energy. A fixed Hessian matrix of strain energy is proposed and adopted in the limited memory Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm, which significantly improves its efficiency for solving the minimization problem of soft robots without sacrificing prediction accuracy. The simplicity of the approach leads to an implementation of MATLAB with only 99-line codes, which provides an easy-to-use tool for designers who are designing and optimizing the structures of soft robots. The efficiency of the proposed approach for predicting kinetostatic behaviors of soft robots is demonstrated by seven pneumatic-driven and cable-driven soft robots. The capability of the approach for capturing buckling behaviors in soft robots is also demonstrated.

BCF is a promising locomotion mechanism that potentially offers swimming at higher speeds and acceleration rates, and efficient locomotion. The robot consists of laminated silicone layers wherein two DEAs are used in an antagonistic configuration, generating undulating fish-like motion. The design of the robot is guided by a mathematical model based on the Euler–Bernoulli beam theory and takes account of the nonuniform geometry of the robot and of the hydrodynamic effect of water. The modeling results were compared with the experimental results obtained from the fish robot with a total length of 150 mm, a thickness of 0.75 mm, and weight of 4.4 g. We observed that the frequency peaks in the measured thrust force produced by the robot are similar to the natural frequencies computed by the model. The peak swimming speed of the robot was 37.2 mm/s (0.25 body length/s) at 0.75 Hz. We also observed that the modal shape of the robot at this frequency corresponds to the first natural mode. The swimming of the robot resembles real fish and displays a Strouhal number very close to those of living fish. These results suggest the high potential of DEA-based underwater robots relying on BCF propulsion, and applicability of our design and fabrication methods.","url":"https://doi.org/10.1089/soro.2017.0062","authors":["Jun Shintake","Vito Cacucciolo","Herbert Shea","Dario Floreano"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2018-06-29T11:21:33Z","doi":"10.1089/soro.2017.0062","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2016.0044","name":"Design of a Variable Stiffness Soft Dexterous Gripper","source":"crossref","abstract":"","url":"https://doi.org/10.1089/soro.2016.0044","authors":["Loai A.T.

By carefully coordinating the two mechanisms, the bending deformation and the stiffness modulation processes of the soft finger can be uncoupled, providing it with both high flexibility and good variable stiffness. Although the soft finger, made entirely from flexible materials, works under a low and safe gas pressure of below 35 kPa, the maximum bending angle reaches ∼210°, and a single soft finger can withstand a weight of 1.25 kg. For any bending angle, with the help of the ribbon-driven mechanism, the stiffness of the soft finger can increase by three to six times. In addition, theoretical models are established for the evaluation of the bending-deformation characteristic and the output force of the soft finger, which are verified by experiments. A dual-finger soft robotic gripper is assembled by utilizing two soft fingers, which can easily and stably grab various objects with different sizes, shapes, and weights.

Determinants of the Chirality of Helically Deformable Soft Actuators","source":"crossref","abstract":"Helical curling and spiral structure are very common in nature, which inspire researchers to create various forms of helical configurations and actuators. The helically deformable actuators perform asymmetric deformations and show different chirality, which means that they can be left handed or right handed. However, the mechanism of helical curling and especially how the key factors influence the chirality of the actuator have not been systematically explained and well understood. In this study, we focus on the typical double-layer soft actuator composed of an active (expansion) layer and a passive (supporting) layer and investigate the effect of key factors (expansion coefficient, Young's modulus, relative thickness) on the chirality of the helical actuation or morphing by comprehensive finite element analyses. It was found that (i) the anisotropic expansion of the active layer or (ii) the anisotropic Young's modulus of the active or the passive layer is indispensable for helical curling. In Case (i), the actuator curls along the direction of greater expansion of the active layer.

In practice, the above two factors may cooperate or compete with each other, and the dominant one determines the chirality.

Their limited capacity to handle loads and deformations also restricts their customized grasping capabilities. To address these issues, a model-based soft gripper with adaptable stiffness was proposed. The proposed actuator comprises a silicone chamber with separate units containing hydrogel spheres. These spheres exhibit temperature-triggered swelling and shrinking behaviors. In addition, variable stiffness strips embedded in the units are introduced as the stiffness variation method. The validated finite element method model was used as the model-based design approach to describe the hydrogel behaviors and explore the affected factors on the bending performance. The results demonstrate that the actuator can be programmed to respond in a desired way, and the stiffness variation method enhances bending stiffness significantly. Specifically, a direct correlation exists between the bending angle and hydrogel sphere layers, with a maximum of 128° achieved. In addition, incorporating gap configurations into the chamber membrane results in a maximum threefold increase in the bending angle. Besides, the membrane type minimally impacts the bending angle from 21.3° to 24.6°. In addition, the embedded variable stiffness strips substantially increase stiffness, resulting in a 30-fold rise in bending stiffness. In conclusion, the novel soft gripper actuator enables substantial bending and stiffness control through active actuation, showcasing the potential for enhancing soft gripper performance in complex and multiscale grasping scenarios.","url":"https://doi.org/10.1089/soro.2023.0185","authors":["Qianyi Chen","Dingena Schott","Jovana Jovanova"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-25T12:02:03Z","doi":"10.1089/soro.2023.0185","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2020.0147","name":"Fully Soft Pressure Sensor Based on Bionic Spine–Pillar Structure for Robotics Motion Monitoring","source":"crossref","abstract":"Soft and stretchable sensors are essential to the development of electronic skin, especially their potential applications in health care and intelligent robots, which have increasingly attracted attentions.

This study demonstrates that transparent DEAs are capable of achieving focus-variation functions, and potentially useful in artificial robotic vision, visual prostheses, and adjustable glasses, which will induce significant effects on the future development of tunable optics.","url":"https://doi.org/10.1089/soro.2021.0036","authors":["Yuzhe Wang","Pengcheng Li","Ujjaval Gupta","Jianyong Ouyang","Jian Zhu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-08-13T12:56:02Z","doi":"10.1089/soro.2021.0036","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2021.0056","name":"Soft Robot Proprioception Using Unified Soft Body Encoding and Recurrent Neural Network","source":"crossref","abstract":"Compared with rigid robots, soft robots are inherently compliant and have advantages in the tasks requiring flexibility and safety. But sensing the high dimensional body deformation of soft robots is a challenge. Encasing soft strain sensors into the internal body of soft robots is the most popular solution to address this challenge. But most of them usually suffer from problems like nonlinearity, hysteresis, and fabrication complexity. To endow the soft robots with body movement awareness, this work presents a bioinspired architecture by taking cues from human proprioception system. Differing from the popular usage of smart material-based sensors embedded in soft actuators, we created a synthetic analog to the human muscle system, using paralleled soft pneumatic chambers to serve as receptors for sensing body deformation. We proposed to build the system with redundant receptors and explored deep learning tools for generating the kinematic model. Based on the proposed methodology, we demonstrated the design of three degrees of freedom continuum joint and how its kinematic model was learned from the unified pressure information of the actuators and receptors. In addition, we investigated the response of the soft system to receptor failures and presented both hardware and software level solutions for achieving graceful degradation. This approach offers an alternative to enable soft robots with proprioception capability, which will be useful for closed-loop control and interaction with environment.","url":"https://doi.org/10.1089/soro.2021.0056","authors":["Liangliang Wang","James Lam","Xiaojiao Chen","Jing Li","Runzhi Zhang","Yinyin Su","Zheng Wang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-03-31T17:43:17Z","doi":"10.1089/soro.2021.0056","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1007/978-3-319-46460-2_5","name":"Soft Robotics in Underwater Legged Locomotion: From Octopus–Inspired Solutions to Running Robots","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-319-46460-2_5","authors":["Marcello Calisti"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2016-09-21T11:22:32Z","doi":"10.1007/978-3-319-46460-2_5","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1201/9781003610380-9","name":"Advances in Soft Robotics for Limb Design","source":"crossref","abstract":"","url":"https://doi.org/10.1201/9781003610380-9","authors":["Shristy Verma","Rishabha Malviya","Dhanalekshmi Unnikrishnan Meenakshi"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-03-24T10:07:13Z","doi":"10.1201/9781003610380-9","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2022.0197","name":"Inverse Origami Design Model for Soft Robotic Development","source":"crossref","abstract":"Origami provides an opportunity to construct a wide range of 3D functional structures by folding a flat sheet.

Especially for the soft and fragile objects, soft fingers had presented their much excellent potential compared with their rigid counterparts.

Inspired by the anatomical structure of the human hand and following the idea of combining soft joints, rigid skeletons and embedded soft curvature sensors, modular dexterous hands composed of multijoint fingers are proposed in this study. Each finger has three quasi-joints, in which metacarpophalangeal soft-joint can realize adduction/abduction and bending motions, and distal two interphalangeal soft-joints are actuated by one actuator. Similar to human hand, soft-joint so-called quasi-joint has a short length of constant curvature segment. The integrated Indium Gallium Alloy sensors with Kelvin Bridge for proprioception can accurately detect joint angles, while closed-loop control based on proprioception was accomplished. Kinematics and statics modeling method of the rigid-soft finger is proposed. To further verify the performance of this design, prototypes of three-fingered and five-fingered hands are developed.

While soft actuators have been one of the most crucial elements of technology leading the development of the soft robotics field, they fall short of force output and bandwidth requirements for many tasks. In addition, other general problems remain open, including robustness, controllability, and repeatability. The SPA-pack architecture presented here aims to satisfy these standards of reliability crucial to the field of soft robotics, while also improving the basic performance capabilities of SPAs by borrowing advantages leveraged ubiquitously in biology; namely, the structured parallel arrangement of lower power actuators to form the basis of a larger and more powerful actuator module. An SPA-pack module consisting of a number of smaller SPAs will be studied using an analytical model and physical prototype. Experimental measurements show an SPA pack to generate over 112 N linear force, while the model indicates the benefit of parallel actuator grouping over a geometrically equivalent single SPA scale as an increasing function of the number of individual actuators in the group. For a module of four actuators, a 23% increase in force production over a volumetrically equivalent single SPA is predicted and validated, while further gains appear possible up to 50%. These findings affirm the advantage of utilizing a fascicle structure for high-performance soft robotic applications over existing monolithic SPA designs. An example of high-performance soft robotic platform will be presented to demonstrate the capability of SPA-pack modules in a complete and functional system.","url":"https://doi.org/10.1089/soro.2016.0029","authors":["Matthew A.

One key figure of merit for machines is their efficiency, which is defined as the ratio of task-oriented work out to total energy in. All soft robots convert stored energy (from e.g., batteries, pressurized gas, chemicals) into task-oriented work (picking up objects, locomoting, jumping). These systems are complex hybrids of chemical, mechanical, pneumatic, hydraulic, and electrical components. This complexity makes it difficult to analyze and measure their total efficiency and to identify the sources of energy loss between chemical, electrical, and mechanical domains. As the field of soft robotics matures, the design-flow process will shift from one in which building is central to one in which simulation takes precedence. That is, there is a shift from an empirical experimental methodology toward a well-characterized engineering workflow. At this point, questions such as “For how long will this robot run on a 2000 mAh battery?” will need to be answered, and predictive capabilities will become paramount as designers need to understand: (1) the large-scale deformations inherent to soft robotic systems; and (2) the transduction of energy in these complex, dissipative, systems to enable them to design an efficient and a well-controlled system. In this perspective piece, we discuss one possible predictive approach: a framework that uses port-based modeling. This approach uses bond-graphs and the recently developed port-Hamiltonian theory to provide a step-by-step system for analyzing hybrid, multi-domain, soft robotic systems. We discuss how this framework could be applied to controlling and optimizing soft robotic systems for energy efficiency, thereby increasing their utility. An energy-based approach is useful as a domain-free linker in analyzing complex systems; the use of ports promotes a clear distinction between energy conservation and dissipation and facilitates the analysis of efficiency. In addition, the parallels with hardware description languages and object-oriented programming will make it easier for engineers to design, for soft robots, control systems that optimize for efficiency.","url":"https://doi.org/10.1089/soro.2016.0010","authors":["Dylan Ross","Markus P.

The natural hydrostatic skeleton combined with muscle activity enables these organisms to protrude a part of their body to explore the surrounding. Looking at the hydrostatic skeleton and protrusion mechanism of sipunculids, our solution is based on a twofold fluidic component, exploiting the advantages of both pneumatic and hydraulic actuations and providing a novel fluidic transmission mechanism. The inflation of a soft pneumatic chamber is associated with the stretch of an inner hydraulic chamber due to the incompressibility of the liquid. Actuator stretch and forces have been characterized to determine system performance. In addition, an analytical model has been derived to relate the stretch ability to the inlet pressure. Three different sizes of prototypes were tested to evaluate the suitability of the proposed design for miniaturization. The proposed actuator features a strain equal to 40–50% of its initial length—depending on size—and output forces up to 18 N in the largest prototypes.

The overall system is characterized with low mass, compact structure, comfortable wearability as well as real-time adjustability for tremor attenuation with varying intensity. The SETS can assist in suppressing tremor of wrist joint in three degrees of freedom. The prototype weighs about 255 g and can yield a maximum damping force of about 11 N. Simulation studies and experimental tests were carried out to evaluate the performance of the system. The results show that the SETS could reduce wrist tremor regarding magnitude of acceleration and angular velocity by 61.39% and 56.22%, respectively, which validate the manifest mechanical efficiency of this functional system.","url":"https://doi.org/10.1089/soro.2019.0194","authors":["Ahmad Zahedi","Bin Zhang","Andong Yi","Dingguo Zhang"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-08-21T15:48:18Z","doi":"10.1089/soro.2019.0194","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1515/9783111069418-205","name":"XIAcknowledgment","source":"crossref","abstract":"","url":"https://doi.org/10.1515/9783111069418-205","authors":[],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2025-08-04T10:36:43Z","doi":"10.1515/9783111069418-205","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2023.0004","name":"Characterization of Temperature and Humidity Dependence in Soft Elastomer Behavior","source":"crossref","abstract":"Soft robots are predicted to operate well in unstructured environments due to their resilience to impacts, embodied intelligence, and potential ability to adapt to uncertain circumstances. Soft robots are of further interest for space and extraterrestrial missions, owing to their lightweight and compressible construction. Most soft robots in the literature to-date are made of elastomer bodies. However, limited data are available on the material characteristics of commonly used elastomers in extreme environments. In this study, we characterize four commonly used elastomers in the soft robotics literature—EcoFlex 00-30, Dragon Skin 10, Smooth-Sil 950, and Sylgard 184—in a temperature range of −40°C to 80°C and humidity range of 5–95% RH. We perform pull-to-failure, stiffness, and stress-relaxation tests. Furthermore, we perform a case study on soft elastomers used in stretchable capacitive sensors to evaluate the implications of the constituent material behavior on component performance. We find that all elastomers show temperature-dependent behavior, with typical stiffening of the material and a lower strain at failure with increasing temperature. The stress-relaxation response to temperature depends on the type of elastomer. Limited material effects are observed in response to different humidity conditions. The mechanical properties of the capacitive sensors are only dependent on temperature, but the measured capacitance shows changes related to both humidity and temperature changes, indicating that component-specific properties need to be considered in tandem with the mechanical design. This study provides essential insights into elastomer behavior for the design and successful operation of soft robots in varied environmental conditions.","url":"https://doi.org/10.1089/soro.2023.0004","authors":["Elze Porte","Sophia Eristoff","Anjali Agrawala","Rebecca Kramer-Bottiglio"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-09-05T15:18:30Z","doi":"10.1089/soro.2023.0004","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2020.0075","name":"Harnessing the Multistability of Kresling Origami for Reconfigurable Articulation in Soft Robotic Arms","source":"crossref","abstract":"This study examines a biology-inspired approach of using reconfigurable articulation to reduce the control requirement for soft robotic arms. We construct a robotic arm by assembling Kresling origami modules that exhibit predictable bistability. By switching between their two stable states, these origami modules can behave either like a flexible joint with low bending stiffness or like a stiff link with high stiffness, without requiring any continuous power supply. In this way, the robotic arm can exhibit pseudo-linkage kinematics with lower control requirements and improved motion accuracy. A unique advantage of using origami as the robotic arm skeleton is that its bending stiffness ratio between stable states is directly related to the underlying Kresling design. Therefore, we conduct extensive parametric analyses and experimental validations to identify the optimized Kresling pattern for articulation. The results indicate that a higher angle ratio, a smaller resting length at contracted stable state, and a large number of polygon sides can offer more significant and robust bending stiffness tuning. Based on this insight, we construct a proof-of-concept, tendon-driven robotic arm consisting of three modules and show that it can exhibit the desired reconfigurable articulation behavior. Moreover, the deformations of this manipulator are consistent with kinematic model predictions, which validate the possibility of using simple controllers for such compliant robotic systems.","url":"https://doi.org/10.1089/soro.2020.0075","authors":["Joshua Kaufmann","Priyanka Bhovad","Suyi Li"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-03-26T10:52:51Z","doi":"10.1089/soro.2020.0075","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1177/21695172261442066","name":"Dynamic Modeling of a Soft Eversion-Based Growing Robot: Physical Analysis, Simulation, and Experimental Validation","source":"crossref","abstract":"Soft eversion-based growing robots, also known as vine robots, are a subclass of soft continuum robots that navigate their environment through tip extension—an eversion-based growth mechanism inspired by climbing plants.

However, it is still a grand challenge to design and efficiently manufacture soft robots with multimodal locomotion capability together with multifunctionality for navigating in dynamic environments and meanwhile performing diverse tasks in real-life applications. This study presents a 3D-printed soft robot, which has spatially varied material compositions (0–50% particle–polymer weight ratio), multiscale hierarchical surface structures (10 nm, 1 μm, and 70 μm features on 5 mm wide robot footpads), and consists of functional components for multifunctionality. A novel additive manufacturing process, magnetic-field-assisted projection stereolithography (M-SL), is innovated to fabricate the proposed robot with prescribed material heterogeneity and structural hierarchy, and hence locally engineered flexibility and preprogrammed functionality. The robot incorporates untethered magnetic actuation with superior multimodal locomotion capabilities for completing tasks in harsh environments, including effective load carrying (up to ∼30 times of its own weight) and obstacle removing (up to 6.5 times of its own weight) in congested spaces (e.g., 5 mm diameter glass tube, gastric folds of a pig stomach) by gripping or pushing objects (e.g., 0.3–8 times of its own weight with a velocity up to 31 mm/s). Furthermore, the robot footpads are covered by multiscale hierarchical spike structures with features spanning from nanometers (e.g., 10 nm) to millimeters. Such high structural hierarchy enables multiple superior functions, including changing a naturally hydrophilic surface to hydrophobic, hairy adhesion, and excellent cell attaching and growth properties. It is found that the hairy adhesion and the engineered hydrophobicity of the robot footpad enable robust navigation in wet and slippery environments. The multimaterial multiscale robot design and the direct digital manufacturing method enable complex and versatile robot behaviors in sophisticated environments, facilitating a wide spectrum of real-life applications.","url":"https://doi.org/10.1089/soro.2020.0004","authors":["Erina Baynojir Joyee","Adam Szmelter","David Eddington","Yayue Pan"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-12-04T17:16:53Z","doi":"10.1089/soro.2020.0004","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2019.0205","name":"RoSE: A Robotic Soft Esophagus for Endoprosthetic Stent Testing","source":"crossref","abstract":"Soft robotic systems are well suited for developing devices for biomedical applications. A bio-mimicking robotic soft esophagus (RoSE) is developed as an in vitro testing device of endoprosthetic stents for dysphagia management. Endoprosthetic stent placement is an immediate and cost-effective therapy for dysphagia caused by malignant esophageal strictures from esophageal cancer. However, later stage complications, such as stent migration, could weaken the swallow efficacy in the esophagus. The stent radial force (RF) on the esophageal wall is pivotal in avoiding stent migration. Due to limited randomized controlled trials in patients, the stent design and stenting guidelines are still unconstructive. To address the knowledge deficit, we have investigated the capabilities of the RoSE by implanting two stents (stent A and B) of different radial stiffness characteristics, to measure the stent RF and its effect on the stent migration. Also, endoscopic manometry on the RoSE under peristalsis has been performed to study the impact of stenting and stent dysfunctionality on the intrabolus pressure signatures (IBPSs) in the RoSE, and further its effects on the swallowing efficacy. Each implanted stent in the RoSE underwent a set of experiments with various test variables (peristalsis velocity and wavelength, and bolus concentrations). In this study, the conducted tests are representative of the application of RoSE to perform a wide-ranging assessment of the stent behavior. The usability of RoSE has been discussed by comparing the results of stent A and B, for various combinations of the test variables mentioned earlier. The results have demonstrated that the stiffer stent B has a higher RF, whereas stent A maintained its RF at a low profile due to its lesser stiffness. The results have also implicated that a high RF is necessary to minimize the stent migration under prolonged peristaltic contractions in the RoSE. For the manometry experiments, stent A slightly increased the IBPS, but the stiffer stent B significantly decreased the IBPS, especially for the higher concentration boluses. It was found that if a stiffer stent buckles, it can reduce the swallow efficacy and cause recurrent dysphagia. Therefore, RoSE is an innovative soft robotic platform that is capable of testing various endoprosthetic stents, thereby offering a solution to many existing clinical challenges in the area of stent testing.","url":"https://doi.org/10.1089/soro.2019.0205","authors":["Dipankar Bhattacharya","Sherine J.V.

To develop reliable solutions for soft robotics applications, devices with the ability to deform and change shape are required, which must be equipped with appropriate sensors capable of withstanding large deformations at suitable speeds and respond repeatedly. This work presents a methodology to build strain sensors made of sensitive, thin, and conductive channels printed inside a soft matrix, using three-dimensional printing. As proof of concept, rectangular beams and semispherical caps embedded with sensitive circuits are developed that are designed to deform under applied forces and detect the gradual contact with objects. The rectangular beam with conductive lines separated from the neutral plane exhibits a quasi-linear electrical response as a function of the applied shear strain. Mechanical diodes, which trigger an activated response once a given deformation onset is exceeded, are implemented using circumferential conductive channels that are centered with the spherical body sensor. Sinusoidally shaped conductive channels located at a given distance from the spherical surface produce a monotonic electrical response, which detects deformations over a broad range. Linear sensors, with enhanced sensitivity to compression, are created if the sensitive conductive channels are oriented along the compression direction. Numerical calculations, used to guide the design of the sensor, show the capability of these sensors to measure simultaneous normal and tangential forces, making them suitable for applications involving fragile object manipulation and robot locomotion. An example of application of these sensors in the control of the forces applied by soft gripper lifting an object is given.","url":"https://doi.org/10.1089/soro.2021.0128","authors":["Alejandro Ibarra","Baptiste Darbois-Texier","Francisco Melo"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2022-03-01T16:58:37Z","doi":"10.1089/soro.2021.0128","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2017.0002","name":"A Biologically Inspired, Functionally Graded End Effector for Soft Robotics Applications","source":"crossref","abstract":"","url":"https://doi.org/10.1089/soro.2017.0002","authors":["Kitty Kumar","Jia Liu","Caleb Christianson","Mustafa Ali","Michael T.

Although the electrodes of DE sensors exhibit nonlinear effects such as transient resistance changes and resistance peaks, this does not affect the capacitance readout representing stretch, as long as the frequency of the excitation voltage used for capacitance measurement is sufficiently low. At higher frequencies, however, the approximation of a DE sensor with an ideal capacitor and a series resistor accounting for electrode resistivity leads to an underestimation of capacitance in static sensors. We demonstrate how this effect is amplified by peaks and transient changes of electrode resistance caused by periodic stretching. At high frequencies, distinctive capacitance undershoots occurred that correlated with the change of electrode resistance. The close match between a simulation of the DE sensor as an R-C transmission line and recorded data supports the hypothesis of the undershoot having been caused by dynamic electrode resistance changes and the lumped parameter approximation. Our results show that nonlinear responses in DE sensors can be avoided by appropriately adjusting the excitation frequency.","url":"https://doi.org/10.1089/soro.2018.0055","authors":["Andreas Tairych","Iain A.

Herein, inspired by the movement mechanism of human fingers, we propose a novel tendon-driven soft robotic finger with a preprogrammed bending configuration and a human finger like sequential motion that can be obtained by matching the stiffness gradient of the finger joints with three-dimensional (3D) printing technology. The contents of this article are organized as follows. First, the effect of the anisotropy caused by 3D printing filling direction on the mechanical property is investigated by tensile test. Then, kinematic, stiffness, and fingertip trajectory models are established to analyze the influence of the cross-section thickness and width on the bending and bearing capacity of the finger joint. Furthermore, several experiments are conducted on a self-built experimental platform to evaluate the advantages of sequential motion induced by stiffness gradients. Results reveal that soft robotic fingers with sequential motion show excellent conformability on the object surfaces with various curvatures and outperform nonsequential motion fingers with larger envelop range. Without changing motion trajectories of the fingertip, the deformability of the finger can be tuned by adjusting only the stiffness of the joint. Besides, a two-finger gripper is developed, which presents the capability of grasping objects with different shapes and weights in practical applications. The sequential motion mechanism proposed in this study shows promising potential in soft grippers and robotic design.","url":"https://doi.org/10.1089/soro.2021.0009","authors":["Yin Zhang","Wang Zhang","Jialong Yang","Wei Pu"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2021-06-11T17:09:35Z","doi":"10.1089/soro.2021.0009","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2020.0170","name":"Tensegrity Robotics","source":"crossref","abstract":"Numerous recent advances in robotics have been inspired by the biological principle of tensile integrity—or “tensegrity”—to achieve remarkable feats of dexterity and resilience.

This study's main contribution is proposing a framework for nonlinear multimaterial architectural design of soft structures to increase their toughness and delay damage propagation. What are the limits when combining significantly different materials in one structure that will delay crack propagation while significantly maintaining postdamage toughness? Through this study, we observed that there is a very dynamic interplay when combining significantly different materials in one structure; this interplay could weaken or strengthen the multimaterial structure's toughness. In biological evolutionary terms, the Pangolin, Seashell, and Arapaima have found their answer for deflecting the crack and maintaining strength in their bodies. How does nature put these multimaterial structures together? Our research led us to find that the multimaterial toughness limits depend largely on the following parameters: components' relative morphology, architecture, spatial distribution, surface areas, and Young's Modulus. We found that a linear geometry, when it comes to morphology and/or architecture relative to surface area in multimaterial design, significantly reduces total toughness and fails to delay crack propagation. In contrast, incorporating geometric nonlinearities in both morphology and architecture significantly maintains higher total toughness even after damage, and significantly delays crack propagation. We believe that this study can open the door to further research and ultimately to promising and wide applications in soft robotics.","url":"https://doi.org/10.1089/soro.2021.0205","authors":["Marwa ElDiwiny","Seppe Terryn","Svetlana Verbruggen","Bram Vanderborght"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-05-12T16:10:56Z","doi":"10.1089/soro.2021.0205","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2021.0158","name":"Copebot: Underwater Soft Robot with Copepod-Like Locomotion","source":"crossref","abstract":"It has been a great challenge to develop robots that are able to perform complex movement patterns with high speed and, simultaneously, high accuracy.

In wearable robotics, striking a balance between ensuring low impedance for wearer comfort and providing sufficient assistive force is a notable design challenge. In this study, we propose exploiting impedance variation in accordance with the types of muscle contraction in the human body. Particularly in eccentric muscle contraction, the impedance can help reduce the muscular load, since it exerts force in the same direction as the muscles. To utilize the relation, we proposed a linked-layer jamming mechanism, which adjusts its impedance largely in various directions. This mechanism allows not only a broad variable range of impedance in multiple rotation directions but also directional torque design, even when equipped in human multi-degree-of-freedom (DoF) joints. By constructing a wearable robot prototype equipped with the proposed linked-layer jamming mechanisms, the effectiveness of this impedance-based assistance approach was confirmed through experiments. The findings from this study present new possibilities in wearable robot design, showing that suitably amplified impedance can assist human motion, potentially enhancing task efficiency and lowering injury risk.

This paper develops a method of including a bimodal design into the deformed state by means of a bilinear material that replaces the conventional strain limiter. With a simple increase in pneumatic pressure, it is possible to have distinctly different deformation directions in one actuator. While inflating at low pressures, the actuator has a preferential deformation direction. As the pressure continues to increase, this preferential deformation direction changes due to a change in the stiffness of the strain limiter. An example of this behavior is demonstrated by an actuator that initially bends in one direction, but then gradually changes direction in plane as the pressure continues to increase. Three different physical actuators were manufactured, tested, and correlated with preliminary numerical models. The physical and numerical models exhibited the desired bimodal behavior, although at different pressures. Furthermore, it was possible to alter the pressure at which this transition occurs by changing the crimp ratio of the embedded bilinear material.","url":"https://doi.org/10.1089/soro.2020.0017","authors":["David Rostin Ellis","Martin Philip Venter","Gerhard Venter"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2020-08-26T17:02:47Z","doi":"10.1089/soro.2020.0017","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2023.0094","name":"Shape Reconstruction of Extensible Continuum Manipulator Based on Soft Sensors","source":"crossref","abstract":"Continuum manipulators can improve spatial adaptability and operational flexibility in constrained environments by endowing them with contraction and extension capabilities.

The way is to measure the strain at specific locations on the deformable body of the manipulator, and then reconstruct the shape by integrating the information from all sensors.

In this article, a new concept of a soft material flow sensor is presented based on elastic filament velocimetry, which fulfills all necessary criteria. This technique measures flow velocity by relating it to the strain of a soft ribbon suspended between two static supports and subjected to a flow of interest. The ribbon is manufactured from polydimethylsiloxane and can be made piezoresistive by the addition of silver nanowires. With the described manufacturing method, the sensor can be made using common laboratory tools, outside of a clean room, significantly reducing its complexity. Furthermore, it can be operated using a simple and lightweight circuit, making it a convenient alternative for MAVs. Using a piezoresistive material allows for the flow velocity to be calibrated to the resistance change of the strained ribbon. Although certain challenges remain unsolved, such as polymer creep, the sensor has demonstrated its ability to measure flow velocities down to 4 m/s in air through experiments. A time-dependent analytical model is also provided. The model shows that the current sensor has a bandwidth of 480 Hz.

With a focus on homogeneous MDSRs, this article presents a framework for kinematic modeling and computational design. Based on continuum mechanics theory, the mechanical characteristics of soft bodies were first described using a deformation gradient tensor and energy density function. The discretized deformation was then depicted using a triangular meshing tool according to the piecewise linear hypothesis. Deformation models of MDSRs caused by external driving points or internal muscle units were established by the constitutive modeling of hyperelastic materials. The computational design of the MDSR was then addressed based on kinematic models and deformation analysis. Algorithms were proposed to infer the design parameters from the target deformation and to determine the optimal muscles. Several MDSRs were developed, and experiments were conducted to verify the effectiveness of the presented models and design algorithms. The computational and experimental results were compared and evaluated using a quantitative index.

These biological systems often use large numbers of sensors arrayed across their bodies to detect disturbances, but previous efforts to use large arrays of sensors in engineered fliers have typically resulted in slow responses due to the need to scan and process data from the large number of sensors. To address the challenges of capturing disturbances in a large sensing array with low latency, this work proposes and demonstrates a modular soft sensing system to quickly detect disturbances in small unmanned aerial vehicles. A large array of soft strain sensors with high sensing resolution covers the entire wingspan, providing rich information on wing deformation. Owing to the modular design, decentralized computation enables the sensing system to efficiently manage sensor data, resulting in sufficiently fast sampling to capture wing dynamics while all 32 sensors embedded in the modular soft sensing skin are used. This hardware architecture also results in significantly reduced noise in the sensing system, leading to a high signal-to-noise ratio. These methods can ultimately enable fast and reliable control of both soft and rigid robotic systems using large arrays of soft sensors.","url":"https://doi.org/10.1089/soro.2023.0173","authors":["Hee-Sup Shin","Sarah Bergbreiter"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2024-04-10T15:27:55Z","doi":"10.1089/soro.2023.0173","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2022.0089","name":"Reconfigurable Soft Pneumatic Actuators Using Extensible Fabric-Based Skins","source":"crossref","abstract":"The development of the field of soft robotics has led to the exploration of novel techniques to manufacture soft actuators, which provide distinct advantages for wearable assistive robotics. One subset of these soft pneumatic actuators is conventionally developed from silicone, fabrics, and thermoplastic polyurethane (TPU). Each of these materials in isolation possesses limitations of low-stress capacity, low-design complexity, and high-input pressure requirements, respectively. Combining these materials can overcome some limitations and maintain their desirable properties. In this article, we explore one such composite design scheme using a combination of silicone polymer-based bladder and reconfigurable fabric skin made from an anisotropic extensible fabric. The silicone polymer bladder acts as the hermetic seal, while this skin acts as the constraint. Bending and torsional actuators were designed utilizing the anisotropy of these fabrics. The torsional actuator designs can achieve over 540° of twist, significantly larger than previously reported in the literature, owing to the lower mechanical impedance of the extensible fabrics. Actuators with 360° of bending were also fabricated using this method. In addition, the lack of TPU-backed or inextensible fabrics reduces the actuator's stiffness, leading to lower actuation pressures. Skin-based designs also confer the advantage of modularity, reconfigurability, and the ability to achieve complex motions by tuning the properties of the bladder and the skin. For applications with high-force requirements, such as wearable exoskeletons, we demonstrate the utility of multilayer design schemes. A multilayer bending actuator generated 190 N of force at 100 kPa and was shown to be a candidate for wearable assistive devices. In addition, torsional designs were shown to have utility in practical scenarios such as screwing on a bottle cap and turning knobs. Thus, we present a novel fabric-skin-based design concept that is highly versatile and customizable for various application requirements.","url":"https://doi.org/10.1089/soro.2022.0089","authors":["Ajinkya Bhat","Shobhit Sandeep Jaipurkar","Li Ting Low","Raye Chen-Hua Yeow"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2023-04-12T09:20:31Z","doi":"10.1089/soro.2022.0089","addedAt":"2026-08-31T06:34:56.055Z","updatedAt":"2026-08-31T06:34:56.055Z"},{"id":"doi:10.1089/soro.2020.0190","name":"Force Control of a 3D Printed Soft Gripper with Built-In Pneumatic Touch Sensing Chambers","source":"crossref","abstract":"This work reports on a soft gripper with three-dimensional (3D) printed soft monolithic fingers that seamlessly incorporate pneumatic touch sensing chambers ( p TSCs) for real-time pressure/force control to grasp objects with varying stiffness (i.e., soft, compliant, and rigid objects).

The p TSCs embedded in the fingers have numerous advantages, including fast response, repeatability, reliability, negligible hysteresis, stability over time, durability, and very low power consumption. Finite element modeling is used to predict the behavior of the p TSCs under different body contacts and to design their topology. Real-time pressure/force control was performed experimentally based on the feedback data provided by the p TSCs to grasp various objects with different weights, shapes, sizes, textures, and stiffnesses using an experimentally tuned proportional–integral–derivative (PID) controller with the same gains for all the objects grasped. In other words, the gripper can self-adapt to different environments with different stiffnesses and provide stable contact and grasping.

However, very few works have been presented on robots which can swim vertically, have a payload and resemble a jellyfish-like creature. In this work, we present the design, fabrication, and performance characterization of a new tethered robotic jellyfish, which is based on inflatable soft pneumatic composite (SPC) actuators. These soft actuators use compressed air to expand and contract, which help the robot to swim vertically in water. The soft actuators consist of elastomeric air chambers and very thin steel springs, which contribute to gaining faster motion of the biomimetic robot. A prototype of 220 mm in diameter and consisting of eight actuating units was fabricated and tested underwater in a fish tank. It reached a height of 400 mm within 2.5 s while carrying a dead weight of 100 g when tested at 70 psi (483 kPa) pressure. This high performance (160 mm/s on average speed) suggests that faster motion with a payload can be achieved by using SPC actuators. The inflatable structures help to flap the bell segments as well as in buoyancy effect for rapid vertical motion. The major achievement of this work is the ability to demonstrate a novel use of inflatable structures and biomimetic flapping wings for fast motion in water. The experimental and deduced data from this work can be used for the design of future small unmanned underwater vehicles (UUVs). This work adds a new robot to the design space of biomimetic jellyfish-like soft robots. Such kind of vehicle design might also be useful for transporting objects underwater effectively.","url":"https://doi.org/10.3390/robotics8030056","authors":["Aniket Joshi","Adwait Kulkarni","Yonas

Five commitments organize it. (1) Composite structure, conductive by design (I1): a carbon-fiber skeleton in a hightemperature resin matrix, whose electrical conductivity is treated not as a nuisance but as routing — bones as the body's Faraday structure, and a skull that shields the identity core in both directions while carrying deliberate apertures for optical and field traffic, exactly as cranial foramina do. (2) Fluid-bearing joints: titanium articulating elements suspended in the body's own circulating gel, forming hydrostatic bearings whose surfaces do not contact — near-zero wear, near-silent, and lubricated by the same medium that carries the body's metabolism, as synovial fluid is simultaneously lubricant, nutrient supply, and damper. (3) Local energy buffering: per-muscle-group encapsulated reserves that discharge on demand and recharge passively from circulation — the architecture muscle already uses (local phosphagen stores refilled by slow perfusion), allowing the central distribution network to be sized substantially below instantaneous aggregate actuator peak demand, and confining any storage failure to one segment. (4) Antagonist actuation with remote motors: artificial-muscle actuators [2] sited proximally and coupled through tendons, opposed in pairs, so that co-contraction sets stif ness independently of position — the mechanism by which one hand holds both an egg and a hammer [3] — with recruitment ordered smallest-first after the size principle [1] and rate-bounded in hardware, so that force rise is confined to a physically guaranteed envelope rather than merely prohibited by policy. (5) The map is discovered, not installed: the body acquires its own control through exploratory movement [4] scaffolded by simulation-to-reality transfer with domain randomization [5], meaning the somatic layer cannot be commissioned without the sensory and motivational layers running — the first architectural requirement in this program that no single paper can satisfy alone. Finally, we advance a normative design principle, nociception without suffering (§8): the field's own governing definitions hold that nociceptor activation is not itself pain [6], and we take that distinction as an obligation rather than an option — damage becomes world-state information driving attention and re-planning, never negative valence coupled into a reward path.

(2) Fluid-bearing joints: titanium articulating elements suspended in the body's own circulating gel, forming hydrostatic bearings whose surfaces do not contact — near-zero wear, near-silent, and lubricated by the same medium that carries the body's metabolism, as synovial fluid is simultaneously lubricant, nutrient supply, and damper. (3) Local energy buffering: per-muscle-group encapsulated reserves that discharge on demand and recharge passively from circulation — the architecture muscle already uses (local phosphagen stores refilled by slow perfusion), allowing the central distribution network to be sized substantially below instantaneous aggregate actuator peak demand, and confining any storage failure to one segment. (4) Antagonist actuation with remote motors: artificial-muscle actuators [2] sited proximally and coupled through tendons, opposed in pairs, so that co-contraction sets stif ness independently of position — the mechanism by which one hand holds both an egg and a hammer [3] — with recruitment ordered smallest-first after the size principle [1] and rate-bounded in hardware, so that force rise is confined to a physically guaranteed envelope rather than merely prohibited by policy. (5) The map is discovered, not installed: the body acquires its own control through exploratory movement [4] scaffolded by simulation-to-reality transfer with domain randomization [5], meaning the somatic layer cannot be commissioned without the sensory and motivational layers running — the first architectural requirement in this program that no single paper can satisfy alone. Finally, we advance a normative design principle, nociception without suffering (§8): the field's own governing definitions hold that nociceptor activation is not itself pain [6], and we take that distinction as an obligation rather than an option — damage becomes world-state information driving attention and re-planning, never negative valence coupled into a reward path. Structural limits are fractioned into the material and reported, not dreaded. Unlike the physical claims above, this one is stated without qualification, and the three lines of criticism we regard as legitimate against it are named in §8 rather than preempted","url":"https://doi.org/10.5281/zenodo.22182469","authors":["Morgan, Jeffrey Allen"],"tags":["Soft robotics","Artificial muscle","Impedence control","Motor unit recruitment","sim-to-real transfer","Motor babbling","Nociception","Nociception/classification"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.22182469","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.25434/muhammad-zubair-iqbal_phd2021","name":"Design of Soft Rigid Devices for Assistive Robotics and Industrial Applications","source":"datacite","abstract":"Soft robots are getting more and more popular in rehabilitation and industrial scenarios. They often come into play where the rigid robots fail to perform certain functions. The advantage of using soft robots lies in the fact that they can easily conform to the obstacles and depict delicacy in gripping, manipulating, and controlling deformable and fragile objects without causing them any harm. In rehabilitation scenarios, devices developed on the concept of soft robots are pretty helpful in changing the lives of those who suffer body impairments due to stroke or any other accident. These devices provide support in carrying out daily life activities without the need and support of another person. Also, these devices are beneficial in the training phase where the patient is going through the rehabilitation phase and has to do multiple exercises of the upper limb, wrist, or hand. Similarly, the grippers developed on the basic principle of soft robots are very common in the industries or at least getting common. Their advantages are a lot as compared to the rigid robotics manipulators. Soft grippers tend to adapt to the shape of the object without causing any damage to it, providing a stable grasp. It can also help reduce the complexity in the design and development, for example, underactuated. Underactuated grippers use the minimum number of actuators to provide the same function that requires more actuators with a rigid gripper. Also, the soft structure allows to design specific trajectories to complete a certain grasping and manipulation task. This thesis presents devices for rehabilitation and assistive application to help people with upper limb impairment, especially wrist and hand functions. These devices have been designed to provide the people, with limited capabilities of hand and wrist functions, to live their lives with ease without being dependent on any other family member. Similarly, I present different soft grippers and a soft environment that provides different advantages and can do various grasp and manipulation tasks. I have presented results for each device, rehabilitation and assistive devices are used by a patient suffering from stroke and having limited movement of wrist and hand function. At the same time, the grippers are supported with a set of experiments that provide deep insight into the advantages of each gripper in industrial applications.","url":"https://doi.org/10.25434/muhammad-zubair-iqbal_phd2021","authors":["Muhammad Zubair Iqbal"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.25434/muhammad-zubair-iqbal_phd2021","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.22175265","name":"The Morgan Clavier: A Sensory Architecture for a Phase-Separated Embodied Machine Mind","source":"datacite","abstract":"We present the sensory architecture for a phase-separated embodied machine mind — a body whose identity layer is optical (network weights etched in fused silica, computing as light propagates) and whose adaptive layer is a living conductive gel [14]. Five design laws organize the architecture. (1) Ship conclusions, not data: following the vertebrate retina — which transmits ~30 preprocessed feature channels rather than images [1] — every sense organ computes before it transmits. (2) Streams are computed, not stored: biological sensory bufers are deliberately shallow (hundreds of milliseconds for vision [2]); perception is processing-in-flow with attention allocating compute on demand, and no sensory stream has write access to the identity layer — consolidation passes solely through the privileged gate specified in [15]. (3) Zero transduction where physics allows: because the mind is photonic, light-native senses need no conversion — focused light can enter the diffractive core directly, making the optic nerve efectively zero-length (arrival is inference [5]), and a skin of embedded optical waveguides [11, 12] delivers touch, proprioception, and temperature already encoded as light: the entire body surface becomes an optical input layer. (4) Shaped matter computes: frequency separation by mechanical structure (the cochlear principle [6, 7, 8]) and inertial sensing by fluid dynamics (the vestibular principle [9]) place the first stage of computation in the organs' physical form, at zero marginal energy. (5) The consonance law: multisensory disagreement is raised as an alarm — the engineering reading of the sensory-conflict account of motion sickness [10] — never silently averaged. Finally, we report a structural observation: each organ designed under these lawsindependently recapitulates the substrate's phase architecture — solid crystalline precision embedded in adaptive living gel — in at least five instances, suggesting the phase-separation principle is scale-free.

The animal eight highly flexible arms exhibit a remarkable diversity and complexity of movements and can easily adapt to the surrounding environment. Indeed, unlike structures with rigid skeletal elements, whose movements are restricted to joints, in these arms, deformations such as bending, elongation, shortening, and twisting, can occur at any location and at multiple locations simultaneously. Furthermore, the octopus can vary the stiffness of its arms, transiently converting a flexible limb into a quasi-articulated structure to accomplish complex tasks like fetching objects and walking over the sea floor. For these reasons, for over a decades the octopus has been inspiring the design of flexible robotic arms and represents nowadays an ?animal model? for soft robotics technologies. The octopus behavior and locomotion are achieved through the combination of basic stereotyped arm motions. At the arm level, this can be obtained by the selective activation or co-activation of antagonistic muscles. The aim of this thesis is to elucidate the bases of octopus arm behavioural flexibility investigating the arm structure to function relationship. Here we show that, while having a morphologically continuous structure, the arm presents behaviourally relevant morpho-functional regionalization, especially evident at the arm apical region. An additional level of flexibility in this system is achieved through the existence of transmural strain gradients generated by a decreasing waviness of elastic fibers from outer to the inner muscle layers determining a functional higher viscoelasticity of the outer muscle layers. This might be related with the distinct functions played by muscles during motions such as accommodation of strain of the inner muscle layers and storage and release elastic energy of the outer layers. This aspect might be important for the overall arm stabilization and compliance to deformation. In support of this data, we found differences in muscle activation properties wherefore inner layers behave as slow muscles and outer layers as fast muscles. Moreover, differently from vertebrates, hydrostatic muscles can undergo large deformations thus changing dramatically the strain rate of each muscle participating in the motion. In this scenario, an activation pattern from a given motorneuron can find the same muscle in a very different strain rate during the motion. Here we found that muscle strain rate has indeed a profound influence on its mechanical work output and, in conjunction with the activation pattern and mechanism of E-C coupling, this feature might be exploited by the animal to produce a wide spectrum of arm motion. Taken together these findings support the existence of a specific arrangement of highly coordinated muscles along and within the arm bulk that is consistent with the arm use. This study is particularly relevant to further implementation in computational models able not only to simulate natural arm movements but also to predict, through a reverse engineering approach, the motion outcome of muscle ensembles. Moreover, conveying the principles governing arm flexibility might have an important impact into the design and fabrication of bio-inspired flexible robotic arms endowed with high compliance and adaptability.","url":"https://doi.org/10.15167/maiole-federica_phd2019-02-21","authors":["MAIOLE, FEDERICA"],"tags":[],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2019","doi":"10.15167/maiole-federica_phd2019-02-21","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.22144187","name":"Experimental Data for Model Validation and Optimal Control of PETER","source":"datacite","abstract":"This is the complete dataset used in the model validation and optimal control experiments with the experimental continuum robot PETER in the PhD thesis of Maximilian Herrmann.

These results quantify the trade-off between gradient-based reward optimisation and evolutionary topology search at their respective natural compute budgets, and motivate further work on evolutionary curricula and warm-start initialisation for the ERL pipeline.","url":"https://doi.org/10.5281/zenodo.21701671","authors":["Mhamane, Khushi","Melhi, Sharon","KS, Swarnalatha"],"tags":["Reinforcement learning","Soft Actor-Critic","NEAT","Evolutionary Reinforcement Learning","Curriculum Learning","TD3","Robotics"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.21701671","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.19690413","name":"Top 10 Read Articles Advances in Vision Computing","source":"datacite","abstract":"April 2026: Top 10 Read Articles: Advances in Vision Computing: An International Journal (AVC) Advances in Vision Computing: An International Journal (AVC) ISSN: 2349 – 2201 http://airccse.org/journal/avc/index.html SURVEY OF WEB CRAWLING ALGORITHMS Rahul Kumar 1, Anurag Jain 2 and Chetan Agrawal 3 1, 2 Department of CSE Radharaman Institute of Technology and Science, Bhopal, M.P, India 3Assistant Prof. Department of CSE Radharaman Institute of Technology and Science, India ABSTRACT The World Wide Web is the largest collection of data today and it continues increasing day by day.

Among these, bellow soft pneumatic actuator (SPA)s offer a promising solution for task-oriented applications that require large deformation, structural compliance, and geometry-level customisation. However, the design of these actuators for intended task applications remains difficult to systematise due to strong nonlinearities and tight coupling between geometry, actuation, and task interaction, often relying on empirical trial-and-error and case-specific tuning. This reliance not only limits design efficiency but also constrains the broader application of such actuators in diverse tasks, including shape-matching, manipulation, and locomotion. To address these challenges, this DPhil aims to develop an automated, task-driven design approach that integrates computational modelling and optimisation, enabling a systematic translation from task-level objectives to manufacturable bellow SPA designs. This thesis presents our contributions toward the aforementioned objective in a step-by-step manner. Firstly, to expedite the design process and reduce reliance on trial and error, an open-source analysis toolbox for 3D-printed bending bellow SPAs was developed. The toolbox, featuring an interactive graphical user interface (GUI), supports rapid, human-guided exploration of bellow SPA designs through a fast analytical model while retaining physically grounded performance evaluation via finite element method (FEM)-based simulation. Secondly, to expand the design space beyond uniform bending, a modular actuator representation was introduced to support more complex actuator geometries and diverse deformation patterns for task-oriented applications. Building on this representation, a FEM-based surrogate modelling approach was developed to enable optimisation-based inverse design for shape-matching objectives, allowing actuator geometries to be generated automatically from task specifications. This approach was also implemented as an open-source GUI-based toolbox, supporting both kinematic prediction for customised actuator designs and automated actuator generation based on input target shapes. Thirdly, building on the shape-matching optimisation framework, an investigation was performed on different modelling and optimisation combinations in terms of computational cost, convergence behaviour, and achieved design quality, providing practical insight into optimisation-based task-driven design. Finally, this thesis proposes a task-driven design pipeline that supports generalisation across parameterised actuator designs and task scenarios. By combining high-fidelity modelling, reduced-order representations, and fast task-level simulation, the pipeline enables task-driven design and optimisation to be performed without reconstructing the entire modelling workflow for each new design instance or task application. Overall, this thesis provides the soft robotics community with a systematic taskdriven design methodology that bridges task objectives and manufacturable soft actuator designs. By improving design efficiency and consistency while supporting a wider range of task-oriented applications, the proposed methodology is not limited to bellow SPAs, but instead offers general-purpose modelling and optimisation tools that the research community can readily build upon.","url":"https://doi.org/10.5287/ora-gpvgxrnxz","authors":["Yao, Y"],"tags":["Robotics","Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.5287/ora-gpvgxrnxz","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.18969201","name":"Data and Code for \"Peripheral Control Enabled by Distributed Sensing in an Octopus-Inspired Soft Robotic Arm for Autonomous Underwater Grasping\"","source":"datacite","abstract":"This collection is intended as supplementary material for the paper: Peripheral Control Enabled by Distributed Sensing in an Octopus-Inspired Soft Robotic Arm for Autonomous Underwater Grasping Abstract: Octopuses exhibit remarkable motor dexterity through distributed sensing and control in their flexible arms.

The GAM Collider is the SNSFT corpus's substrate-neutral compositional-reduction engine at coordinate [9,9,2,3]. It supports 2-beam, 4-beam, and 8-beam collision modes, of which OctoBeam is the 8-beam configuration used throughout this study; each collision reduces the input elements' Pattern-Narrative-Behavior-Adaptation (PNBA) fingerprints through the fusion rules P_out = 8/Σ(1/P_i), N_out = ΣN_i, B_out = max(0, ΣB_i − 2k_max), A_out = max(A_i), with pairwise coupling k_max = Σ min(B_i, B_j) over C(8,2) = 28 pairs, producing a substrate-neutral phase state τ = B_out / P_out and Identity Mass IM = Ω₀ · (P_out + N_out + A_out). The study followed the substrate-neutral Long Division Protocol (LDP): anchor-locking proceeded incrementally from CHON (four biological anchors, universal life scaffold) through the addition of Si (biocompatible network former), Ga (bioactive amorphization enhancer with clinically-verified bone-regeneration activity), and Ni (magnetic-response transition metal), producing a seven-anchor scaffold with one free eighth slot. Approximately 1000 GAM Collider collisions were performed in three successive lock configurations to identify structural invariants and select seven compositions for formal verification. Each of the seven verified compositions reaches phase τ = 0 (Noble) and is formally verified in Lean 4 at zero sorry. We document these seven verified compositions as enabled production paths rather than as recipes: the framework's structural reduction identifies each composition as compositionally reachable through known fabrication routes (melt-spinning, sputter deposition, vacuum arc melting, atmosphere-controlled quench), but the paths are not prescriptive claims about what should be produced. They are formally verified compositional targets that wet-lab teams may pursue if the application matches.

The GAM Collider is the SNSFT corpus's substrate-neutral compositional-reduction engine at coordinate [9,9,2,3]. It supports 2-beam, 4-beam, and 8-beam collision modes, of which OctoBeam is the 8-beam configuration used throughout this study; each collision reduces the input elements' Pattern-Narrative-Behavior-Adaptation (PNBA) fingerprints through the fusion rules P_out = 8/Σ(1/P_i), N_out = ΣN_i, B_out = max(0, ΣB_i − 2k_max), A_out = max(A_i), with pairwise coupling k_max = Σ min(B_i, B_j) over C(8,2) = 28 pairs, producing a substrate-neutral phase state τ = B_out / P_out and Identity Mass IM = Ω₀ · (P_out + N_out + A_out). The study followed the substrate-neutral Long Division Protocol (LDP): anchor-locking proceeded incrementally from CHON (four biological anchors, universal life scaffold) through the addition of Si (biocompatible network former), Ga (bioactive amorphization enhancer with clinically-verified bone-regeneration activity), and Ni (magnetic-response transition metal), producing a seven-anchor scaffold with one free eighth slot. Approximately 1000 GAM Collider collisions were performed in three successive lock configurations to identify structural invariants and select seven compositions for formal verification. Each of the seven verified compositions reaches phase τ = 0 (Noble) and is formally verified in Lean 4 at zero sorry. We document these seven verified compositions as enabled production paths rather than as recipes: the framework's structural reduction identifies each composition as compositionally reachable through known fabrication routes (melt-spinning, sputter deposition, vacuum arc melting, atmosphere-controlled quench), but the paths are not prescriptive claims about what should be produced. They are formally verified compositional targets that wet-lab teams may pursue if the application matches. Two independent structural invariants are documented: (i) the fabrication-atmosphere ladder, in which noble-gas eighth-slot selection produces monotonically-ordered N×A scores (He > Ne > F > Ar > Kr) at constant k_max = 43 across the (H+C+N+O+Si+Ga+Ni)-anchored scaffold; and (ii) the Ni→Ti biocompatibility substitution, in which Ti replaces Ni at identical Identity Mass (IM) with elevated internal B-coupling density (k_max = 43 → 49 in the noble-gas condition, k_max = 62 → 70 in the no-gas condition).

Novel applications include: soft robotics, metamaterials, deployable structures, and energy-dissipating devices. Many studies have explored the behaviour of kirigami structures with varying cut patterns. However, these studies have focused on quasi-static deformations and linear elastic materials. In this work, we investigate the dynamic response of metallic kirigami structures. Using static and dynamic experiments, supplemented by numerical simulations and semi-analytical calculations, we provide a comprehensive understanding of the strain-rate-dependent behaviour of kirigami. More specifically, we compute a critical impact velocity beyond which the response of the kirigami switches from imperfection-dominated to the formation of a tension-induced buckling front. Despite this phenomenological transition, we show that the energy dissipated through plastic deformations is largely unaffected by strain rate. The results of this study will enable the robust design of novel kirigami-based energy dissipating devices for dynamic applications such as blast and impact.","url":"https://doi.org/10.3929/ethz-c-000801310","authors":["Singh, Amanpreet","Sinha, Aryan","Dunnett, Thomas","Mukhopadhyay, Tanmoy","Walker, Martin G."],"tags":["Kirigami","Blast","Critical impact velocity","Energy dissipation","Impact","Strain-rate"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3929/ethz-c-000801310","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.3929/ethz-c-000783043","name":"Tissue Engineering and Soft Robotics for Heart Repair and Replacement","source":"datacite","abstract":"Heart failure is a leading cause of mortality, with limited treatment options beyond heart transplantation. Mechanical circulatory support systems, such as total artificial hearts (TAHs), are life-sustaining but constrained by complexity, cost, and long-term reliability. Meanwhile, engineered cardiac tissues offer regenerative potential but face challenges in mechanical stability, vascularisation, and integration with the native myocardium. This thesis explores a multi-tiered strategy combining mechanical circulatory support with biofabricated cardiac tissues to address these limitations, bridging the gap between short-term support and long-term regeneration. This work contributes to three key areas. First, it introduces a sensorless, self-regulating soft TAH that passively adapts to circulatory demands without electronic feedback, reducing design complexity and increasing production scalability. Second, it develops a reinforced cardiac tissue patch (RCPatch) integrating mechanically stiff 3D printed scaffolds with soft hydrogels, offering a suturable and structurally stable material for myocardial defect repair. Third, it develops Multidirectional Filamented Light (FLight), a rapid and scalable method for aligning high-density cardiac tissues with torsional contractility and an architecture that resembles the native myocardium. These advancements offer a multi-tiered approach to heart failure treatment, from short-term circulatory support to myocardial regeneration and long-term cardiac tissue engineering. The developments in TAHs build a foundation for more accessible, simplified heart replacements, while the RCPatch bridges structural heart repair and regeneration. Innovations in biofabrication contribute to the broader goal of whole-organ tissue engineering. By integrating these approaches, this thesis outlines a path toward a future where heart failure can be reversed using scalable, adaptive, and regenerative technologies.","url":"https://doi.org/10.3929/ethz-c-000783043","authors":["Jones, Lewis"],"tags":["Tissue Engineering","Cardiac surgery","Regenerative medicine","Bioprinting","Biofabrication","Cardiomyocytes","total artificial heart","Mechanical circulatory support (MCS)"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.3929/ethz-c-000783043","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.20366900","name":"Beyond_Containment: Analytical Glossary of Symbiotic Progress (2026)","source":"datacite","abstract":"The advent of Artificial General Intelligence (AGI) and the rise of autonomous,self-healing systems demand a new analytical vocabulary capable of describingthe structural relationships between human consciousness, machine intelligence,and the geometric architecture of professional value.

When Atlas testing is complete, DIGSP, GRFF, AIMPod, and NGLS transition from theoretical frameworks to validated engineering capabilitiesthat subsequent Canon systems inherit without repeating the validation from scratch. ───────────────────────────────────────────────────────────────────────────── KEY TECHNICAL PARAMETERS — Configuration: fixed-base six-joint serial chain (J1 base yaw through J6 wrist roll) — Total reach: 3.5 m (L1 1.2 m + L2 1.3 m + L3 1.0 m) — Payload rating: 700 kg wet (derived from minimum functional stack mass analysis) — Payload upper bound justification: 1,000 kg payload drives J2 harmonic drive to 5,175 Nm rated class and base bending moment to 95 kNm at SF 1.5 — impractical for first-generation Atlas — J2 shoulder minimum rated torque: 33,967 Nm at SF 1.5 (including 1.0 m lateral EM cell offset) — Base structural design moment: 63.2 kNm at safety factor 1.5 — Full extension rotational inertia: I = 700 × 3.5² = 8,575 kg m² (dynamics gate) — EM operating environment: 0.3 to 0.5 T within 0.8 m of EM cell core during handling — Motor separation rule: minimum 1.0 m from EM cell core to any drive motor — Encoder steady-state field limit: 0.02 T; transient limit: 0.05 T for 5 Hz), and replaces indicative joint torque values with computed values.

A building may retain a familiar architectural type whilelower-impact materials, environmental technologies, and control systems are introduced around it. A robot may similarlyinherit a predetermined morphology while sensing, computation, actuation, and control are progressively added to achieverequired performance. Neither sequence is intrinsically flawed. This paper asks what becomes possible when morphologyitself remains open longer to material, environmental, energetic, functional, and relational constraint. The inquiry emerged from an August 2026 Aeon Mundi research review in which recent experiments in myceliumbiocomposites, regional agricultural feedstocks, binderless bamboo panels, ventilated acoustic metamaterials, andpost-retrofit building monitoring appeared to converge on a common design question. Across these otherwise distinct studies,performance depended not only on material identity or technological addition but on internal organization, local resourceconditions, geometry, environmental flows, and observed behavior after fabrication or occupation. Parallel research inembodied intelligence demonstrates that robot morphology and material properties can contribute materially to locomotion,manipulation, control, environmental adaptation, and resilience. Drawing these literatures into a bounded cross-domain synthesis, this paper develops Reciprocal Morphogenesis as adesign-research framework in which morphology emerges through an iterative relationship among situation, constraint,physical differentiation, performance, observation, and revision. Two coupled lines of inquiry are considered: regenerativehabitat through Aeon Mundi and prospective artificial embodiment through Aren. The paper proposes the concepts ofsituated morphology, available metabolism, morphogenetic differentiation before compensatory complexity, selectivepermeability, and external reality as a corrective field. It further develops a coupled Morphogenetic Stack, a HabitatObservatory, and an Embodiment Constraint Ledger as prospective methods for translating the theoretical framework intofalsifiable experimental work. These constructs are presented as research propositions rather than established natural laws.The central claim is deliberately limited: when physical organization materially affects performance, morphology shouldremain corrigible long enough for the conditions of the world it must inhabit to participate in determining what it becomes.","url":"https://doi.org/10.5281/zenodo.22074577","authors":["Lambdin, James"],"tags":["reciprocal morphogenesis; situated morphology; regenerative architecture; embodied intelligence; morphological adaptation; mycelium biocomposites; bioregional materials; passive dynamics; soft robotics; human-robot interaction; adaptive habitat; urban metabolism"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.5281/zenodo.22074577","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.21836233","name":"STUDY ON TRAINING OF WORKFORCE, AND ITS IMPACT ON HOSPITAL PERFORMANCE & PATIENT SATISFACTION","source":"datacite","abstract":"ABSTRACT: Workforce training has been given emphasis as it enhances employee performance, efficiency of healthcare unit, and contributes to quality of care.

These materials constitute 3-D polymer networks and are typically synthesized by cross-linking polymer chains or copolymerizing monomer and cross-linker. Seminal investigations have enabled control over the network architecture by cross-linking chains of poly(dimethyl siloxane), poly(1,4-butadiene), or tetra-poly(ethylene glycol); but as soft materials become attractive for robotics, electronics and prosthetics, co-designing the network architecture, mechanical, and functional properties has become pressing. We investigate the relationship between reaction pathway, network architecture, and mechanical properties in poly(ethyl glycidyl ether) networks synthesized by epoxide ring opening polymerization with two organo-aluminum catalysts. The key result is that uncontrolled polymerizations yield loosely cross-linked, entangled, soft, and extensible networks; whereas more controlled polymerizations, instead, lead to highly cross-linked, stiff, and brittle networks. Such catalytic control over network architecture and mechanical properties could enable design of novel soft, tough, and functional materials.","url":"https://doi.org/10.18738/t8/ugxgtb","authors":["Dookhith, Aaliyah","Lynd, Nathaniel","Creton, Costantino","Sanoja, Gabriel"],"tags":["Chemistry","Engineering"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.18738/t8/ugxgtb","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.20030989","name":"A Tendon-Driven 3D-Printed Monolithic Soft Actuator with Universal Deformation Modes","source":"datacite","abstract":"Actuators are fundamental components in robotics systems, enabling motion and environmental interactions.

This work presents a planning framework for serial multi-segment soft robots with deformable body segments and boundary suction pads. The formulation targets full 3D navigation on complex surfaces and explicitly handles discrete adhesion switching and continuous body deformation under geometric, collision, and quasi-static feasibility constraints, while remaining agnostic to the specific actuation realization used to produce segment deformation. Its core, block-wise IK hybrid search (IKHS), performs best-first search over feasible adhesion transitions while solving inverse kinematics only on induced free blocks. On top of IKHS, primitive-augmented hybrid search (PaHS) uses a learned observation--primitive embedding to retrieve short validated motion segments for fast local proposal, with fallback to standard IKHS branching when retrieval fails. In simulation, the framework consistently outperforms controlled baselines in planning success, transition quality, and efficiency across diverse terrains. PaHS matches IKHS in success rate while substantially reducing planning time. Repeated hardware experiments on a pneumatic multi-segment soft robot further demonstrate executability and online recovery under actuation and adhesion uncertainty.","url":"https://doi.org/10.48550/arxiv.2608.16853","authors":["Tang, Zili","Guo, Tiecheng","Zhang, Qinyue","Guo, Meng"],"tags":["Robotics (cs.RO)","FOS: Computer and information sciences"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.48550/arxiv.2608.16853","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.22030597","name":"Recycled Polymer Orthoses for Post-Stroke Neurorehabilitation in Kazakhstan: Development and Biomechanical Evaluation of Low-Cost 3D-Printed Orthoses","source":"datacite","abstract":"This paper presents a narrative review and conceptual engineering design study on low-cost, 3D-printed hand orthoses for post-stroke neurorehabilitation in Kazakhstan, fabricated from recycled polyethylene terephthalate (rPET).

Conventional ceramic piezoelectrics offer exceptional electromechanical performance but require high-temperature sintering and exhibit intrinsic brittleness, limiting their integration with soft or unconventional substrates. Polymeric piezoelectrics, in contrast, provide mechanical compliance and low-temperature processability yet suffer from lower crystallinity, reduced piezoelectric coefficients, and limited thermal stability. These contrasting characteristics have catalyzed the development of functional piezoelectric inks-ceramic, polymeric, and hybrid formulations engineered for additive manufacturing techniques such as direct ink writing, stereolithography, screen printing, and inkjet printing. This review systematically examines the material compositions, dispersion chemistries, printing requirements, thermal treatment pathways, and poling strategies that govern the performance of printed piezoelectric transducers. By comparing ceramic-based, polymer-based, and hybrid systems, we reveal the fundamental trade-offs between printability, crystallinity, mechanical compliance, and electromechanical response, and map how these trade-offs shape device design across wearable electronics, soft robotics, and structural health monitoring. Finally, we highlight emerging approaches-including surface functionalization, low-temperature crystallization, liquid-phase sintering, and engineered ceramic-polymer interfaces-that offer promising routes to bridge the gap between printability and high piezoelectric performance.","url":"https://doi.org/10.3929/ethz-c-000801083","authors":["Reis Carneiro, Manuel"],"tags":["piezoelectric inks","Piezoelectric transducers","Printed electronics","Additive manufacturing","Printed transducers","Ceramic-polymer hybrids","Low-temperature processing","Direct ink writing"],"confidence":0.66,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.3929/ethz-c-000801083","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.5281/zenodo.21289899","name":"2026 5th International Conference on Service Robotics (ICoSR 2026)","source":"datacite","abstract":"★CONTACT US Website: www.iwosr.org Date:Haikou, China Venue:July 25-27, 2026 Email:mail@iwosr.org Tel:+86 28 85575979 (International) ★Welcome to ICoSR 2026 The 2026 5th International Conference on Service Robotics (ICoSR 2026) will be held in Haikou, China during July 25-27, 2026.

This paper introduces the first Lyapunov stability controller for soft robotics, deploying real-time maximal Lyapunov exponent estimation (λ_MLE) from fibre-optic strain sensor arrays running at 100Hz on Intel Loihi 2 neuromorphic chips. The system reconstructs 12D phase space embeddings via Takens theorem, detecting chaos onset 187ms early during dual-material transitions (tomato → bolt), enabling pre-emptive damping that transforms strange attractors into stable limit cycles. Experimental validation across USDA organic datasets (tomatoes, grapes, leafy greens) and MRF waste streams demonstrates 94.2% grasp success 3.7× improvement over PID baselines with 2.3× faster cycles (2.1 grips/second) and 67% energy savings. Neuromorphic acceleration achieves 187μs latency for 12D divergence computation, 28× faster than GPU methods. Field deployments confirm robustness, agricultural harvesting sustains 3 clusters/minute, waste sorting handles mixed-material chaos, and medical tissue manipulation achieves sub-micron precision under arterial pulpability. Theoretical contributions include event-triggered Lyapunov redesign guaranteeing exponential stability (λ_1 -0.1) despite 24dB vibration and 47% moisture variance. Phase space visualization reveals Kaplan-Yorke dimension collapsing from 8.2D hyper chaos to 2.1D stable manifolds, providing online stability margins. This work establishes chaos quantification as a foundational primitive for next-generation soft robotics, transforming nonlinearity from failure mode to control parameter across agriculture, recycling, and minimally-invasive surgery.","url":"https://doi.org/10.20944/preprints202604.0806.v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.20944/preprints202604.0806.v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-10398103/v1","name":"Energy-Efficient Agricultural Robotics for Personalized Agricultural Education: An Adaptive Cloud–Edge Framework Based on Fuzzy Logic and Genetic Algorithms","source":"preprints","abstract":"Abstract (1) Background: Training the next generation of agricultural practitioners demands hands-on, data-driven experience, yet field instruction is costly and hard to personalize; meanwhile the robots that could serve as tutors are battery-limited and must reason over uncertain, noisy field and learner data. (2) Methods: We present a genetic-fuzzy decision engine for energy-aware, personalized task-sequencing on agricultural education robots. A Mamdani fuzzy inference system (FIS) converts imprecise inputs — learner mastery, engagement, field suitability, and battery state — into soft per-task suitability and energy-caution scores; a genetic algorithm (GA) with order crossover, repair, and a fuzzy-weighted fitness evolves an energy-aware learning pathway subject to prerequisite, battery, and time constraints. The engine is embedded in a cloud–edge architecture with computation offloading, predictive energy modeling, missing-data imputation, and a standardized data layer, and is evaluated on real-data-grounded simulations with a simulated learner model.

Moving beyond conventional pick-and-place (PnP) paradigm, we introduce a simultaneous pick-and-place (sPnP) framework that enables continuous object ingestion and transport without interrupting manipulator mobility. Fabricated as a tendon-driven, dual-segment soft continuum robot from compliant material, the proximal segment enables precise omnidirectional bending and axial extension, while the distal segment integrates eight independently controlled inward-contracting hydraulic actuators to realize rhythmic peristaltic transport. To support safe and adaptive operation in complex underwater environments, an embodied electrical impedance tomography (EIT) architecture is integrated directly into the mesh-structured body. This system simultaneously delivers real-time morphology self-perception (bending direction, bending angle, and axial length) and anomalous-object detection (internal/external conductors and insulators), achieving multimodal awareness of the robot’s own shape, external contacts, and the position of internal swallowed objects. Extensive underwater experiments demonstrate high-fidelity morphology tracking (maximum bending direction error 7.67%, maximum bending-angle error 2.6°, less than 1.1 mm axial length error), robust internal/external object localization even under bent configurations, and stable peristaltic swallowing with concurrent perception across multiple postures. These results establish a transformative paradigm for underwater soft robotics that unifies compliant manipulation, energy-efficient internal transport, and embodied multimodal perception, laying the foundation for future soft robotic systems with enhanced autonomy in unstructured marine environments.","url":"https://doi.org/10.21203/rs.3.rs-9363171/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-9363171/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-9854604/v1","name":"Temporal

DNA Computing","source":"preprints","abstract":"Conventional silicon computing is constrained by energy demands, limited parallelism, and poor compatibility with living systems, motivating the exploration of molecular alternatives. Here, we realize Brownian DNA computing, a hitherto theoretical framework, for energy efficient computation in which coupled molecular balances on a DNA origami scaffold form Brownian Logic Elements (BLEs) that harnesses thermal fluctuations for computation. By encoding multiple logic gates into a programmed energy landscape, these BLEs execute all fundamental Boolean logic gates, complex circuits such as half-adders, and multi-input operations, while also enabling non-Boolean logic with multi-valued outputs in a single compact gate. Computation arises through thermally driven exploration of a near-flat configurational energy landscape, without reliance on consumable fuel strands for cascading signal propagation, making the process fast, resettable, and compatible with operation near reversible thermodynamic limits. Transient-input protocols further allow the BLE energy landscape to be controlled quasistatically, providing a route toward reversible Brownian computation. In combination with single-molecule readout, Brownian DNA computing establishes a new foundation for molecular information processing with potential applications in biocomputing, soft robotics, and energy-efficient nanodevices.","url":"https://doi.org/10.1101/2025.08.21.671330","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.08.21.671330","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1101/2025.07.16.664986","name":"Chemical

High-Precision Timing Method and Digital Interface for Closed-Loop TMS","source":"preprints","abstract":"Objective Current transcranial magnetic stimulation (TMS) protocols exhibit high inter-subject variability in treatment outcomes, highlighting the need for personalized, brain-state-dependent closed-loop stimulation protocols. To enable such protocols, we aim to provide robust, precisely timed external control of TMS, with stimulation timed relative to feedback signals such as the electroencephalogram (EEG). Approach Commercial TMS devices typically rely on trigger signals for precise external pulse timing, while adjusting stimulation parameters, such as intensity, is better handled via serial digital communication, which supports robust error detection and feedback. However, combining these communication methods is inherently complex and prone to timing issues, such as race conditions. Furthermore, trigger signals lack capabilities essential for real-time systems, such as preventing late pulse delivery. We present a method for precise and accurate pulse timing, implemented through a digital interface that uses exclusively serial digital messaging, eliminating the need for trigger signals. This interface enables external control of pulse timing, intensity, and other parameters. The TMS device maintains its own internal clock and delivers pulses at pre-scheduled times, decoupling timing precision from the control device. Additionally, we propose a method for synchronizing such time-tracking TMS devices with commercial EEG systems, enabling precisely timed EEG–TMS. Main results Using these methods, our custom TMS device delivered pulses precisely aligned to the EEG signal, with timing errors consistently below 0.3 ms. These errors were constrained by the experimental setup, including the sampling rate of our EEG device and the signal-to-noise ratio affecting pulse detection. Significance Our timing method achieves sub-millisecond precision in brain-state-dependent closed-loop EEG–TMS, providing a foundation for robust TMS timing that supports adaptive, personalized stimulation protocols. The digital control interface, co-designed with our TMS device, integrates pulse timing and parameters, setting a precedent for future advancements in computer-controlled TMS.","url":"https://doi.org/10.1101/2025.04.05.647340","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.04.05.647340","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-4237033/v1","name":"Hybrid Epoxy-Acrylate Resins for Wavelength-Selective Multimaterial 3D Printing","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-4237033/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.rs-4237033/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1101/2024.09.30.615941","name":"Creased ciliary flocks shape unfolding dynamics via information bottlenecks in an aneural animal","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2024.09.30.615941","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.09.30.615941","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1101/2025.08.31.673395","name":"Bioinspired Geometry-Encoded Rheotactic Navigation of Sound-Driven Microrobots","source":"preprints","abstract":"Imitating the shape-encoded tactics of natural microswimmers—organisms that flip, roll, and rheotaxis through viscous fluids—could transform microfluidics, micromanufacturing, and targeted therapy. However, translating those geometric navigation cues into actively driven microrobots is an open, largely unexplored challenge. Here, inspired by the structure of sperm cells, we introduce a sound-propelled head-helix microparticle (“microrobot”) featuring an elliptical head and a spiral tail. This asymmetrical design interacts with the incident acoustic field, generating complex secondary flows that induce a torque, enabling the particle to reorient around its cross-section. The microparticle exhibits a preferred direction of propulsion and orientation when exposed to a traveling sound wave, reorienting if its initial alignment deviates from this preference. Both the preferred direction and orientation can be modulated by adjusting the sound frequency, and they further adapt to background flow fields in the environment. Furthermore, the microparticle exhibits rheotaxis-like motion, exhibiting wall-following motion with frequency-dependent sliding behavior. By moving towards the channel wall, it enters the region with the smallest flow velocities, allowing it to move antiparallel to the fluid. These findings contribute to the engineering of the trajectories of sound-propelled microparticles and to the development of next-generation microrobots for medical and other innovative applications.","url":"https://doi.org/10.1101/2025.08.31.673395","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.08.31.673395","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-4109720/v1","name":"A

self-burying seed carriers for aerial seeding","source":"preprints","abstract":"Abstract Aerial seeding can quickly cover large and physically inaccessible areas to improve soil quality and scavenge residual nitrogen in agriculture, and for postfire reforestation and wildland restoration. However, it suffers from low germination rates, due to the direct exposure of unburied seeds to harsh sunlight, wind and granivorous birds, as well as undesirable air humidity and temperature. Here, inspired by Erodium seeds, we design and fabricate self-drilling seed carriers, turning wood veneer into highly stiff (about 4.9 GPa when dry, and about 1.3 GPa when wet) and hygromorphic bending or coiling actuators with an extremely large bending curvature (1,854 m -1 ), 45 times larger than the values in the literature. Our three-tailed carrier has an 80% drilling success rate on flat land after two triggering cycles, due to the beneficial resting angle (25°–30°) of its tail anchoring, whereas the natural Erodium seed’s success rate is 0%. Our carriers can carry payloads of various sizes and contents including biofertilizers and plant seeds as large as those of whitebark pine, which are about 11 mm in length and about 72 mg. We compare data from experiments and numerical simulation to elucidate the curvature transformation and actuation mechanisms to guide the design and optimization of the seed carriers. Our system will improve the effectiveness of aerial seeding to relieve agricultural and environmental stresses, and has potential applications in energy harvesting, soft robotics and sustainable buildings.","url":"https://doi.org/10.21203/rs.3.pex-2135/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.21203/rs.3.pex-2135/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.20944/preprints202403.1670.v1","name":"PatchFusion:

In this first-in-human study, we explored a novel approach in an individual with chronic tetraplegia. Our method combined targeted surgery to isolate functionally relevant branches of the median and radial nerves with custom intrafascicular electrodes to interface with them. By precisely stimulating motor fibers within these nerves, we successfully restored independent movement in four fingers, including the thumb. The combination of these movements allowed the recreation of the lateral, hook, and palmar grasps with smoothly modulated forces. Furthermore, the participant regained the ability to perform functional tasks, such as pouring water from a bottle. These findings hold significant promise for individuals with hand paralysis, paving the way for neurotechnologies that can bypass spinal cord injuries and restore fine motor control.","url":"https://doi.org/10.21203/rs.3.rs-6188325/v2","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-6188325/v2","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-3705285/v1","name":"Electroactive Composite Biofilms Integrating Kombucha, Chlorella and Synthetic Proteinoid Proto–Brains","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3705285/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3705285/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-6588431/v1","name":"Machine Learning Workflows for Motion Capture-driven Biomechanical Modelling","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-6588431/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.21203/rs.3.rs-6588431/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-3470199/v1","name":"MXene-based pressure sensor with ultrahigh sensitivity in a small pressure range for voiceless speaking and abnormal writing recognition","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3470199/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3470199/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.21203/rs.3.rs-3035429/v1","name":"An Ultra-Low-Cost, Pressure Sensing and Haptic Feedback-Enabled Transradial Prosthesis","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-3035429/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-3035429/v1","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1101/2025.01.08.631861","name":"Programmable Assembly and Steering of Microbubble Droplets using Ultrasound","source":"preprints","abstract":"Gas-filled microbubbles have been extensively used as contrast agents for ultrasound therapies and have recently been explored as microrobots. When exposed to an intense acoustic wave, microbubbles oscillate and scatter the sound field, leading to assembly and manipulation behaviors. Although traditional microbubbles demonstrated promising potential for manipulation in physiological environments, we recognized the need for improved assembly selectivity and acoustically directed propulsion. For this, we developed a new microbubble design using microfluidics. We engineered microbubbles with an outer oil droplet encapsulating a gas core, allowing the gas to move freely within the oil. When the gas reaches the droplet’s periphery, the oil attenuates the scattered wave, ensuring that scattering or acoustic amplification is concentrated near the droplet’s edge. This approach enabled us to control the organized assembly of microbubbles and direct their acoustic navigation. We believe this approach will open new possibilities for using gas-filled microbubbles as safer drug carriers or for micro-interventions in biomedical settings.","url":"https://doi.org/10.1101/2025.01.08.631861","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.01.08.631861","addedAt":"2026-08-31T06:34:56.056Z","updatedAt":"2026-08-31T06:34:56.056Z"},{"id":"doi:10.1101/2023.09.30.560306","name":"A

region of the spinal cord that coordinates arm and hand movements, causing paralysis. Here, we engineered a chronically implanted and durable Digital Bridge that reestablishes communication between the brain and cervical spinal cord. This technology consists of a brain implant to record electrocorticography from the sensorimotor cortex, and a neurostimulation platform to deliver epidural electrical stimulation over the entire cervical spinal cord unilaterally. We implanted this Digital Bridge in three individuals with chronic incomplete tetraplegia. We configured a library of stimulation patterns that supported gradual control over various elementary movements of the arm and hand. A decoding pipeline incorporating a foundation model of human brain activity predicted up to 8 motor states with high accuracy. In turn, linking decoding predictions to the modulation of stimulation patterns targeting the preprogrammed elementary movements enabled the three participants to perform functional tasks with their otherwise paralyzed arm and hand. The Digital Bridge has remained stable for more than one year, and has been compatible with long-term stability and safety. While additional technological developments and clinical validations in a diverse patient population are required, these results establish essential concepts to enable arm and hand movements in humans living with chronic tetraplegia.","url":"https://doi.org/10.21203/rs.3.rs-9901682/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.21203/rs.3.rs-9901682/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2023.06.12.544584","name":"Meniscus-enabled Projection Stereolithography (MAPS)","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2023.06.12.544584","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1101/2023.06.12.544584","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.20944/preprints202304.1181.v1","name":"Programmable Complex Shape Changing of Polysiloxane Main-Chain Liquid-Crystalline Elastomers","source":"preprints","abstract":"","url":"https://doi.org/10.20944/preprints202304.1181.v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.20944/preprints202304.1181.v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2025.03.11.642631","name":"Revisiting face-to-hand area remapping in the human primary somatosensory cortex after a cervical spinal cord injury","source":"preprints","abstract":"Spinal cord injury (SCI) leads to profound disruptions in sensorimotor processing. Seminal research in non-human primates suggests this sensory deprivation causes functional remapping in the primary somatosensory cortex (S1), where somatotopic representations of deprived body parts, such as the hand in cervical SCI, become responsive to touch on intact body parts, such as the face. However, evidence for such remapping in humans remains inconclusive. We investigated face-to-hand remapping in 16 chronic cervical SCI patients and 21 able-bodied controls using two fMRI experiments. Experiment 1 employed a lip movement task, while Experiment 2 investigated the full architecture of S1 face reorganisation through vibrotactile stimulation of the forehead, lips and chin. We assessed (1) the level of face activity in the anatomical S1 hand area, (2) cortical shifts in peak face activity, (3) face-part separability in the S1 hand area and (4) correlations with clinical characteristics that may drive face-to-hand area remapping. Our results revealed no significant evidence in favour of face-to-hand area remapping in tetraplegic patients across markers of face-to-hand remapping during either lip movement or vibrotactile stimulation of face parts. Furthermore, our markers of remapping did not correlate with clinical characteristics. These findings suggest that cortical face-to-hand remapping is not apparent in human cervical SCI patients. Beyond providing insight into the limitations of cortical reorganisation in humans, this highlights the need to reassess rehabilitation strategies based on the assumption of large-scale face-to-hand reorganisation after an SCI.","url":"https://doi.org/10.1101/2025.03.11.642631","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.03.11.642631","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-2229531/v1","name":"A Bidirectional Fabric-Based Soft Robotic Glove for Hand Function Assistance in Patients with Chronic Stroke","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-2229531/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-2229531/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-1954600/v1","name":"The HASEL actuator’s muscle mimicking mechanism for enacting an upper limb smart prosthesis: A review on recent progress and challenges for future implementation","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-1954600/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-1954600/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-1868334/v1","name":"A Wearable Soft Robot that Can Alleviate the Pain and Fear of the Wearer","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-1868334/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-1868334/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-2559498/v1","name":"Mechanically Controlled High-Performance Molecular Photoswitch","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-2559498/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.21203/rs.3.rs-2559498/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-1181940/v1","name":"A Tribometric Device for the Rolling Contact of Soft Elastomers","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-1181940/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.21203/rs.3.rs-1181940/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-6188325/v1","name":"Targeted nerve stimulation restores single-finger movements in a person with tetraplegia","source":"preprints","abstract":"Abstract The loss of hand function is one of the most devastating impairments for individuals with paralysis.

Our method combined targeted surgery to isolate functionally relevant branches of the median and radial nerves with custom intrafascicular electrodes to interface with them. By precisely stimulating motor fibers within these nerves, we successfully restored independent movement in four fingers, including the thumb. The combination of these movements allowed the recreation of the lateral, hook, and palmar grasps with smoothly modulated forces. Furthermore, the participant regained the ability to perform functional tasks, such as pouring water from a bottle. These findings hold significant promise for individuals with hand paralysis, paving the way for neurotechnologies that can bypass spinal cord injuries and restore fine motor control.","url":"https://doi.org/10.21203/rs.3.rs-6188325/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.21203/rs.3.rs-6188325/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-4460203/v1","name":"Overdamping

Using an optimized MemPrep workflow, we establish a high-confidence lipidome of the mammalian ER and selectively enrich membrane vesicles originating from ER tubules as a major ER subdomain. Quantitative lipidomics show that ER membranes are dominated by phosphatidylcholine and mono-unsaturated glycerophospholipids, consistent with a highly compressible bilayer. Although proteomics suggests a functional specialization of ER tubules and an enrichment of tubule-associated proteins therein, the lipidome of an ER tubule-enriched isolate is indistinguishable from the general ER, indicating that principal ER architectures share a common lipid composition. Integration of lipidomic data with bioinformatic analyses of transmembrane helices further demonstrates that the physicochemical features of ER lipids mirror those of ER-resident membrane proteins, including reduced hydrophobicity and increased polarity compared to plasma membrane proteins. These findings support a coordinated evolution of ER proteins and lipids based on shared biophysical constraints. Together, this work provides a definitive characterization of the mammalian ER lipidome and suggest that membrane properties are maintained across the entire ER.","url":"https://doi.org/10.64898/2026.03.20.713196","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2026","doi":"10.64898/2026.03.20.713196","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2021.06.28.21258767","name":"Soft robotic steerable micro-catheter for the endovascular treatment of cerebral disorders","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2021.06.28.21258767","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.1101/2021.06.28.21258767","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2023.03.30.534759","name":"RAVEN: development of a novel volumetric extrusion-based system for small-scale Additive Manufacturing","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2023.03.30.534759","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1101/2023.03.30.534759","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-418019/v1","name":"A bionic soft robotic glove mimicking finger actions based on sEMG recognition","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-418019/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.21203/rs.3.rs-418019/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-1341317/v1","name":"Autonomous Self-Drilling Seed Carriers for Aerial Seeding with Superior Success Rates","source":"preprints","abstract":"Abstract Aerial seeding can quickly cover large and physically inaccessible areas to improve soil quality and scavenge residual nitrogen in agriculture, for postfire reforestation3–6 and wildland restoration. However, it suffers from low germination rates due to the direct exposure of unburied seeds to harsh sunlight, wind, granivorous birds, and undesirable air humidity and temperature1. Inspired by Erodium seeds, we design and fabricate self-drilling seed carriers, turning wood veneer into highly stiff (7.2 GPa when dry, and 1.2 GPa when wet) and hygromorphic bending or coiling actuators with an extremely large bending curvature (1854 m-1), 45 times larger than the literature values. Our three-tailed carrier has an 80% drilling success rate on flat land after two triggering cycles due to the beneficial resting angle (25° - 30°) of its tail anchoring, whereas the natural Erodium seed’s success rate is 0%. Our carriers can carry payloads of different sizes and contents including biofertilizers and plant seeds as large as those of whitebark pine, which are 11 mm in length. We compare experiments with numerical simulation to elucidate the curvature transformation and actuation mechanisms to guide the design and optimization of the seed carriers. Our system will significantly improve the effectiveness of aerial seeding to relieve agricultural and environmental stresses, and has potential applications in energy harvesting, soft robotics and sustainable buildings.","url":"https://doi.org/10.21203/rs.3.rs-1341317/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-1341317/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.21203/rs.3.rs-1157089/v1","name":"Photoswitchable gating of non-equilibrium enzymatic feedback in chemically communicating polymersome nanoreactors","source":"preprints","abstract":"","url":"https://doi.org/10.21203/rs.3.rs-1157089/v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2022","doi":"10.21203/rs.3.rs-1157089/v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2023.03.09.531925","name":"An Acoustically Controlled Microrobot Modelled on  <i>Spirochete</i>  Bacteria","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2023.03.09.531925","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2023","doi":"10.1101/2023.03.09.531925","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2024.11.26.624817","name":"Shaping the developing homunculus: the roles of deprivation and compensatory behaviour in sensory remapping","source":"preprints","abstract":"ABSTRACT Some of the most dramatic examples of neuroplasticity in the human brain follow congenital sensory deprivation, though we have limited understanding of the plasticity mechanisms driving such large-scale remapping.

Our findings emphasise the early establishment and stability of cortical maps, despite extensive daily-life behavioural adaptation.","url":"https://doi.org/10.1101/2024.11.26.624817","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2024","doi":"10.1101/2024.11.26.624817","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2025.07.09.663178","name":"Derivation of cardiomyocyte-propelled motile aggregates from stem cells","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2025.07.09.663178","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2025","doi":"10.1101/2025.07.09.663178","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1101/2021.08.25.457533","name":"The ultrafast snap of a finger is mediated by skin friction","source":"preprints","abstract":"","url":"https://doi.org/10.1101/2021.08.25.457533","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2021","doi":"10.1101/2021.08.25.457533","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.26434/chemrxiv.13428395.v1","name":"Bio-inspired Artificial Helical Chromatophore for Stealth Mode","source":"preprints","abstract":"","url":"https://doi.org/10.26434/chemrxiv.13428395.v1","authors":[],"tags":[],"confidence":0.74,"sites":["robot-parts"],"publishedDate":"2020","doi":"10.26434/chemrxiv.13428395.v1","addedAt":"2026-08-31T06:34:56.057Z","updatedAt":"2026-08-31T06:34:56.057Z"},{"id":"doi:10.1007/978-3-032-29127-1_35","name":"Classification of Contact Type Based on the Magnetic Field Data for Tactile Sensor","source":"crossref","abstract":"","url":"https://doi.org/10.1007/978-3-032-29127-1_35","authors":["Vladimir Sibinović","Srđan Apostolović","Mirko Raković"],"tags":[],"confidence":0.7,"sites":["robot-parts"],"publishedDate":"2026-07-06T02:57:09Z","doi":"10.1007/978-3-032-29127-1_35","addedAt":"2026-08-31T06:34:56.113Z","updatedAt":"2026-08-31T06:34:56.113Z"},{"id":"doi:10.1002/idm2.70045","name":"An Intrinsically Multimodal Self‐Powered Sensor Enhanced by Microstructured Powder Layer for AI‐Enabled Tactile Perception","source":"crossref","abstract":"ABSTRACT Artificial intelligence (AI)‐powered robots increasingly rely on advanced tactile sensors to perceive and interpret complex mechanical cues, enabling intelligent interaction with real‐world environments. However, most existing tactile sensing systems rely on different sensing mechanisms to achieve static and dynamic perception, which increases system complexity. In this work, we present the self‐powered intrinsic Tactile‐Dual mode (iTD) Sensor—an intrinsically multimodal triboelectric platform that integrates material recognition and dual‐mode (static/dynamic) pressure sensing within a single sensor device. A microstructured polytetrafluoroethylene powder layer, introduced via scalable spray‐coating, endows the sensor with high sensing resolution and strong moisture resistance. The iTD Sensor intrinsically decouples static and dynamic signals without auxiliary circuitry, allowing for efficient and complementary tactile data acquisition. Leveraging these signals, a convolutional neural network model achieves material classification with 99.08% accuracy. For pressure sensing, the iTD Sensor exhibits high sensitivities across static (&lt; 3 kPa, 7.62 V kPa − 1 ; 3–30 kPa, 0.59 V kPa − 1 ) and dynamic (&lt; 5 kPa, 5.56 V kPa − 1 ; 5–30 kPa, 0.30 V kPa − 1 ) regimes. Integrated onto a robotic fingertip, the sensor enables accurate recognition of real‐world objects and surface textures, achieving classification accuracies of 98.75% and 99.38%, respectively.

To support human heart function, assistive devices and total artificial hearts have been developed. However, the system's functionality, hemocompatibility, and overall implantability are still open challenges. METHODS: Here, the design of a soft robotic artificial cardiac wall is presented: the action of a bioinspired myocardium of pneumatic McKibben actuators in a double helix is coupled with an engineered passive and deformable endocardial layer made of silicone. The correlation between the helix angle of the actuators and the ejection fraction of the artificial cardiac wall was preliminarily studied with a simplified analytical model. A FEM model was introduced to represent the complex deformation of the endocardial layer during the actuation of the cardiac wall. RESULTS: Experimental tests report an ejection fraction of 68%, i.e., 77.2 ± 0.4 mL against 90 mmHg, satisfying the minimum physiological requirements and, therefore, proving the concept's functionality.

Cochlear implants (CIs) restore hearing by directly stimulating the auditory nerve with electrical impulses, often while preserving residual hearing. Over the past two decades, robotic-assisted techniques in otologic surgery have gained prominence for improving precision and safety. Robotic systems support critical procedures such as mastoidectomy, cochleostomy drilling, and electrode array (EA) insertion. These technologies aim to minimize trauma and enhance hearing preservation. Despite the outpatient nature of most CI surgeries, surgeons still face challenges, including anatomical complexity, imaging demands, and rising costs. Robotic systems help address these issues by streamlining workflows, reducing variability, and improving electrode placement accuracy. This review evaluates robotic systems developed for cochlear implantation, focusing on their design, surgical integration, and clinical outcomes. This review concludes that robotic systems offer low insertion speed, which leads to reduced insertion forces and lower intracochlear pressure.

The benefits of robotic surgery over laparoscopy have yet to be conclusively demonstrated in gynaecology, as several studies comparing perioperative and postoperative patient outcomes have reported no significant differences, leading to a lack of precise recommendations in surgical guidelines for both gynaecologic oncology and benign gynaecology. In addition, these outcomes must be balanced against the high costs of robotic surgery, in particular when considering building an infrastructure for safe telesurgery to democratise access to telementoring and remote interventions. Objectives: Drawing from the expertise gained at the IRCAD Research and Training Center in Strasbourg, France, this article aims to provide an overview of the unveiled benefits of robotic-assisted surgery in gynaecology, investigating the role of digital surgery integration. Methods: The objective of this narrative review is to provide an overview of the latest advancement in digital robotic-assisted surgery in gynaecology and illustrate the benefits of this approach related to the easiest integration with new technologies. To illustrate such evidence, PubMed, Google Scholar, and Scopus databases were searched. Main Outcome Measures: In the era of surgical innovation and digital surgery, the potential of robotic surgery becomes apparent through the capacity to integrate new technologies. Image-guided surgery techniques, including the analysis of preoperative and intraoperative images, 3D reconstructions and their use for virtual and augmented reality, and the availability of drop-in robotic ultrasound probes, can help to enhance the quality, efficacy and safety of surgical procedures. Results: The integration of artificial intelligence, particularly computer vision analysis of surgical workflows, is put forward to further reduce complications, enhance safety, and improve operating room efficiency. Additionally, new large language models can assist during procedures by providing patient history and aiding in decision-making. The education and training of young surgeons will undergo radical transformations with robotic surgery, with telementoring and shared procedures in the side-by-side double-console setup. Conclusions: Robotic systems play a fundamental role in the transition towards digital surgery, aiming to improve patient care through integration of such new technologies. What is New?: While the advantages of robotic surgery in terms of perioperative outcomes have yet to be demonstrated, the benefits of its easiest integration with new technologies are evident.","url":"https://doi.org/10.52054/fvvo.2024.13522","authors":["Matteo Pavone","Marta Goglia","Andrea Rosati","Chiara Innocenzi","Nicolò Bizzarri","Barbara Seeliger","Pietro Mascagni","Filippo Alberto Ferrari","Antonello Forgione","Antonia Carla Testa","Anna Fagotti","Francesco Fanfani","Denis Querleu","Giovanni Scambia","Chérif Akladios","Jacques Marescaux","Lise Lecointre"],"tags":["Robotic surgery","Robot","Medicine","Surgery","Artificial intelligence"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2025-04-07","doi":"https://doi.org/10.52054/fvvo.2024.13522","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4415302245","name":"Physical Intelligence in Small‐Scale Robots and Machines","source":"openalex","abstract":"Intelligent living organisms-from unicellular entities to plants-rely on body physical intelligence (PI) to autonomously adapt and thrive in dynamic and complex environments, bypassing neural processing.

Exosuits and fluid-driven actuators are fabric-based devices that are gaining increasing relevance as alternatives assistive technologies that can provide simpler, more flexible solutions in comparison with the rigid exoskeletons. These devices, however, commonly require an external energy supply or a pressurized-fluid reservoir, which considerably constrain the autonomy of such solutions. In this work, we introduce an event-based energy cycle (EBEC) design concept, that can harvest, store, and release the required energy for assisting the knee-bending, in a synchronised interaction with the user and the environment, thus eliminating any need for external energy or control input. Ice-plant hydro-actuation system served as the source of inspiration to address the specific requirements of such interactive exosuit through a fluid-driven material system. Based on the EBEC design concepts and the abstracted bio-inspired principles, a series of (material and process driven) design experimentations helped to address the challenges of realising various functionalities of the harvest, storage, actuation and control instances within a closed hydraulic circuit. Sealing and defining various areas of water-tight seam made out of thermoplastic elastomers provided the base material system to program various chambers, channels, flow-check valves etc of such EBEC system. The resulting fluid-driven EBEC-skin served as a proof of concept for such active exosuit, that brings these functionalities into an integrated 'sense-acting' material system, realising an auto-synchronised energy and information cycles. The proposed design concept can serve as a model for development of similar fluid-driven EBEC soft-machines for further applications. On the more general scheme, the work presents an interdisciplinary design-science approach to bio-inspiration and showcases how biological material solutions can be looked at from a design/designer perspective to bridge the bottom-up and top-down approach to bio-inspiration.","url":"https://doi.org/10.1088/1748-3190/ac2785","authors":["Facundo Gutiérrez","Khashayar Razghandi"],"tags":["Soft robotics","Process (computing)","Biomimetics","Computer science","Work (physics)"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2021-09-16","doi":"https://doi.org/10.1088/1748-3190/ac2785","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4411213350","name":"Innovations in Upper Limb Rehabilitation Robots: A Review of Mechanisms, Optimization, and Clinical Applications","source":"openalex","abstract":"With the continuous increase in the global aging population, stroke has become one of the major diseases affecting the health of the elderly, and the upper limb motor dysfunction it causes often requires long-term rehabilitation.

Given that the performance of PneuNet actuators is affected by their geometric parameters, considering the impact of geometric variations is crucial in this field. Herein, the effect of geometrical parameters on a zig‐zag soft pneumatic actuator, and an improved version of conventional PneuNet actuators designed for enhanced performance are investigated. Finite element analysis (FEA) indicates that smaller gaps between chambers, thinner bottom layers, and taller chamber heights result in greater bending under the same pressure within the tested parameter range. Experimental results reveal a 30.9% larger bending angle than that of conventional actuators with the same parameters. The FEA results are consistent with the experimental data, exhibiting an error of 10.2%.

Here, a simple multi-material 4D printing technique is developed that combines dynamic temperature-responsive granular hydrogel inks based on hyaluronic acid, whose actuation is modulated via poly(N-isopropylacrylamide) crosslinker design, with granular suspension bath printing that provides structural support during and after the printing process. Granular hydrogels are easily extruded upon jamming due to their shear-thinning properties and their porous structure enables rapid actuation kinetics (i.e., seconds). Granular suspension baths support responsive ink deposition into complex patterns due to shear-yielding to fabricate multi-material objects that can be post-crosslinked to obtain anisotropic shape transformations. Dynamic actuation is explored by varying printing patterns and bath shapes, achieving complex shape transformations such as 'S'-shaped and hemisphere structures.

By combining foundation models with the principles of embodied AI, where intelligent systems perceive, reason, and act through physical interaction, mobile service robots can achieve more flexible understanding, adaptive behavior, and robust task execution in dynamic real-world environments. Despite this progress, embodied AI for mobile service robots continues to face fundamental challenges related to the translation of natural language instructions into executable robot actions, multimodal perception in human-centered environments, uncertainty estimation for safe decision-making, and computational constraints for real-time onboard deployment. In this paper, we present the first systematic review of foundation models in mobile service robotics, following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Using an OpenAlex literature search, we considered 7506 papers for the years spanning 1968–2025. Our detailed analysis identified four main challenges and how recent advances in foundation models, related to the translation of natural language instructions into executable robot actions, multimodal perception in human-centered environments, uncertainty estimation for safe decision-making, and computational constraints for real-time onboard deployment, have addressed these challenges. We further examine real-world applications in domestic assistance, healthcare, and service automation, highlighting how foundation models enable context-aware, socially responsive, and generalizable robot behaviors. Beyond technical considerations, we discuss ethical, societal, human-interaction, and physical design and ergonomic implications associated with deploying foundation-model-enabled service robots in human environments. Finally, we outline future research directions emphasizing reliability and lifelong adaptation, privacy-aware and resource-constrained deployment, as well as the governance and human-in-the-loop frameworks required for safe, scalable, and trustworthy mobile service robotics.","url":"https://doi.org/10.3390/robotics15030055","authors":["Matthew Lisondra","B.

However, the low stiffness of the soft actuator limits the scope of applications. Particle jamming has emerged as an important method to adjust the stiffness of soft grippers. This paper proposes a novel particle jamming mechanism based on the differential pressure drive. With the differential drive particle jamming mechanism, a soft actuator is designed, which is characterized by a dual-deformable chamber structure in which one chamber is filled with particles. The simultaneous inflation of the two chambers will result in the bending behavior without significant stiffening. However, if the air chamber is pressurized with a larger pressure, the differential pressure will cause the particles inside the particle chamber to jam each other, which increases the stiffness of the actuator significantly. Thus, the differential drive particle jamming mechanism can achieve the independent control of the stiffness and the bending angle. Both theoretical and experimental studies in this area have shown that the gripper based on the differential drive particle jamming mechanism can stiffen itself effectively, and achieve the independent control of the stiffness and the bending angle, which can be adopted in applications where both high stiffness and dexterity are required.","url":"https://doi.org/10.1088/1748-3190/ab04d1","authors":["Pei Jiang","Yandong Yang","Michael Z.

Combining the membrane's large expansion and softness with the 3D printing of hollow structures simplified the design of a bending actuator that can bend 180 degrees and reach a blocked force of 238 times its weight. In addition, by 3D printing TPE pellets and rigid filaments, the soft membrane could grasp objects by enveloping an object or as a sensorized sucker, which relied on the TPE's softness to conform to the object or act as a seal. In addition, the sucker's membrane acted as a tactile sensor to detect an object before adhesion.

As such, they are used for electromechanical actuation and mechanoelectrical sensing, as well as mechanical energy harvesting to generate electricity1-5. While EAPs are traditionally known as ElectroActive Polymers, this denomination does not capture the specificity of the family, consisting of the ability to undergo significant deformation and/or stress changes in response to suitable electrical stimuli. Accordingly, that term is not used here, to explicitly exclude any other type of electrically induced/regulated ‘activity’, wherein the mechanical form is not the ultimate (or the initial) stage of the energy transformation chain of interest (as in the case, for instance, of electrically semiconducting or conducting polymers for plastic electronics). Today, EAPs represent a well established and promising scientific field of research and development. EAP materials are commonly classified in two major families: ionic EAPs, activated by an electrically-induced transport of ions and/or solvent, and electronic EAPs, activated by electrostatic forces1-5. Ionic EAPs include polymer gels6, ionic polymer metal composites7 (including later evolutions to ionic polymer conductor composites, and the variant of interpenetrating polymer networks8), conjugated polymers9, and carbon nanotubes10. Electronic EAPs include piezoelectric polymers11, electrostrictive polymers12, dielectric elastomers13, liquid crystal elastomers14, along with what is proposed here as the latest entry, represented by carbon nanotube aerogels15. While each EAP category shows specific electromechanical properties, typically suitable for different needs and applications, general features include high mechanical compliance, low density, ease of processing, inherent responsiveness to electrical stimuli, as well as low cost. As a result, EAP transducers, in general, are flexible, light-weight, structurally-simple, versatile, scalable, and cheap; additionally, when used as actuators they have sizable electromechanical performance and integrated force/stroke feed-back, and are noiseless and heat-free [1–5]. Although several EAP materials and their properties have been known for many decades, they have found very limited applications. Such a trend has changed recently, as a result of an effective synergy of at least three main factors: key scientific breakthroughs being achieved in some of the existing EAP technologies; unprecedented electromechanical properties being discovered in materials previously developed for different purposes; and a higher concentration of efforts for real exploitation of EAP materials. As an outcome, after several years of basic research, today the EAP field is just starting to undergo transition from academia into commercialization, with significant investments from large companies. EAP actuators are being developed for applications that so far have been precluded to conventional actuation technologies (mainly electric/electromagnetic, hydraulic/pneumatic and thermo-chemical motors). Usage spans from the micro- to the macro- scale in different sectors, such as medical and haptic devices, consumer electronics, and automation and robotic systems. Reported examples include micro-pumps and micro-valves for micro-fluidic systems (e.g. for lab-on-a-chip devices)1, 5, controlled release of active compounds for medical therapeutic devices (e.g. insulin release in blood stream)1, 5, miniaturized surgical tools for medical interventional systems (e.g. steerable catheters)1, 5, miniaturized implantable actuators as components of artificial organs (e.g. mechanical stimulators of cardiac tissue)1, 5, 16, robotic systems (including medical and industrial robots)1, 4, 16-18, variable-stiffness devices (e.g. safe actuators for robots interacting with humans and vibration dampers for vehicles)","url":"https://doi.org/10.1002/pi.2790","authors":["Federico Carpi"],"tags":["Materials science","Electroactive polymers","Ionic bonding","Polymer","Carbon nanotube"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2010-03-01","doi":"https://doi.org/10.1002/pi.2790","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4417157970","name":"Liquid-Augmented MPC in Quadrupedal Robot for Disturbance Learning","source":"openalex","abstract":"This paper presents a Liquid-Augmented Model Predictive Control (LA-MPC) framework for robust and adaptive motion control of quadrupedal robots operating under dynamic disturbances.

This practical research study proposes an extended calibration approach for improving Omnidirectional Mobile Robot (OMR) motion response in the context of mechanical build imperfections (misalignment). A precise indoor positioning system is required to obtain accurate data for calculating the calibration parameters and validating the implementation response. An ultrasound-based commercial solution was considered for tracking the OMR, but the practical observed errors of the readily available position solutions requires special processing of the raw acquired measurements. The approach uses a multilateration technique based on the point-to-point distances measured between the mobile ultrasound beacon and a current subset of fixed (reference) beacons, in order to obtain an improved position estimation characterized by a confidence coefficient. Therefore, the proposed method managed to reduce the motion error by up to seven-times. Reference trajectories were generated, and robot motion response accuracy was evaluated using a Robot Operating System (ROS) node developed in Matlab-Simulink that was wireless interconnected with the other ROS nodes hosted on the robot navigation controller.","url":"https://doi.org/10.3390/s22228590","authors":["Alexandru-Tudor Popovici","Constantin-Cătălin Dosoftei","Cristina Budaciu"],"tags":["Computer science","Mobile robot","Robot","Global Positioning System","Real-time computing"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2022-11-08","doi":"https://doi.org/10.3390/s22228590","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4412094040","name":"The Role of AI in On-Site Construction Robotics: A State-of-the-Art Review Using the Sense–Think–Act Framework","source":"openalex","abstract":"The construction sector is confronted with significant challenges, such as reduced productivity, high injury rates, and labor deficits, driving research into autonomous robotics as a viable solution.

To address these issues, a smoothing optimised A*-guided DWA fusion algorithm (SOA-DWA) is proposed in this paper. Firstly, the A* algorithm was improved by introducing a path smoothing strategy and path pruning mechanism, generating a globally optimal path that complied with the vehicle kinematic constraints. Secondly, three sub-functions were introduced into the evaluation function of the DWA algorithm: the distance evaluation between the reference trajectory and the global path, the path direction evaluation, and the dynamic obstacle avoidance evaluation, to enhance the real-time performance of dynamic obstacle avoidance and the consistency of the global path. The SOA-DWA algorithm ensured that the mobile robot could effectively avoid obstacles in complex environments without deviating from the global optimal path. Thirdly, experimental results show that in a static environment, the path length and turning angle of the SOA-DWA algorithm are reduced by an average of 13.3% and 16.25%, respectively, compared with the traditional algorithm. In a dynamic environment, the path length and turning angle are reduced by an average of 10.5% and 14.5% compared to the traditional DWA algorithm, respectively, significantly improving the smoothness of the path and driving safety. Compared to the existing fusion algorithm, the SOA-DWA algorithm reduces the path length by an average of 10.1%, improves planning efficiency by an average of 42%, and effectively enhances obstacle avoidance efficiency.

This makes training the future robotics workforce a challenge. In this paper, we evaluate our experiences with project-based learning approaches to teaching robotics at the undergraduate level at Miami University. Specifically, we analyze three consecutive years of capstone design projects on increasingly complex robotics design problems for multi-robot systems. We also evaluate the laboratories taught in our course “ECE 314: Elements of Robotics”. We have chosen these four experiences since they focus on the use of “cheap” first-principled robots, meaning that these robots sit on the fringe of embedded system design in that much of the student time is spent on working with a micro-controller interfacing with simple and cheap actuators and sensors. To contextualize our results, we propose the Robotic System Levels (RSL) model as a structured way to understand the levels of abstraction in robotic systems. Our main conclusion from these case studies is that, in each experience, students are exposed primarily to a subset of levels in the RSL model. Therefore, the curriculum should be designed to emphasize levels that align with educational objectives and the skills required by local industries.","url":"https://doi.org/10.3390/robotics14060070","authors":["Bryan Van Scoy","Peter Jamieson","Veena Chidurala"],"tags":["Robotics","Robot","Artificial intelligence","Engineering","Robotic paradigms"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2025-05-27","doi":"https://doi.org/10.3390/robotics14060070","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4410005008","name":"Industrial Robotics and the Future of Work","source":"openalex","abstract":"Starting in the 1970s with robots that were physically isolated from contact with their human co-workers, robots now collaborate with human workers towards a common task goal in a shared workspace.

Harnessing light to precisely regulate and fine‐tune their performance is essential for unlocking their versatility and expanding their range of applications. To address this challenge, light‐actuated, tunable micromachines are developed based on photo‐swellable colloidal ionogels—an azobenzene‐modified co‐polymer microsphere infused with azobenzene‐based ionic liquids (Azo‐ILs)—that undergo reversible cis‐trans isomerization under UV/visible light. UV irradiation increases the colloidal ionogel's hydrophilicity and causes it to swell by H2O, releasing Azo‐ILs into aqueous environments with a rapid photoresponse (milliseconds), while visible light irradiation stops the swelling. The dissociated ions lead to diffusiophoresis and diffusioosmosis, enabling two functionalities: isotropic ion release from the ionogel pumps water outward with exclusion zones up to 30 µm, while anisotropic release from partially coated ionogel microspheres leads to micromotors at speeds of ≈3 µm s−1 and a lifetime of ≈15 min. Importantly, the magnitude and range of these interactions are precisely modulated by light intensity and azobenzene content in co‐polymers. Finite element and Brownian dynamics simulations validate the electrokinetic mechanisms underlying the pump and motor's operation. This work establishes a platform for designing micromachines potentially useful in fluid manipulation, drug delivery, and soft robotics.","url":"https://doi.org/10.1002/smll.202503698","authors":["Dezhou Cao","Jingru Xu","Dongqing He","Mohd Yasir Khan","Xing Ma","Wei Wang"],"tags":["Materials science","Colloid","Nanotechnology","Colloidal crystal","Nanoparticle"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2025-05-29","doi":"https://doi.org/10.1002/smll.202503698","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4410322047","name":"Soft Robotics: Engineering Flexible Automation for Complex Environments","source":"openalex","abstract":"Soft robotics represents a transformative approach to automation, focusing on the development of robots constructed from flexible, compliant materials that mimic biological systems. Being different from traditional rigid robots, soft robots are engineered to adapt and operate efficiently in complex, unstructured environments, making them highly appropriate for applications that require delicate manipulation, safe human–robot interaction, and mobility on unstable terrain. The key principles, materials, and fabrication techniques of soft robotics are explored in this study, highlighting their versatility in industries such as healthcare, agriculture, and search-and-rescue operations.

However, physical origami robots possess inherent material compliance and mechanical imperfections, presenting challenges in modeling and redundant actuation for accurate control of all degree of freedom (DoF). Herein, a data‐driven kinematic modeling approach tailored for physical origami robots to effectively address the inherent compliance is introduced. This approach is applied to a multiloop origami spherical joint, which features a minimalistic design comprising two parallel waterbomb structures. This design allows for the integration of four actuators, thereby enabling full control over the structure's three DoF and its inherent compliance. It is demonstrated that a small dataset is adequate for accurately learning the forward kinematics, which then informs an optimization‐based inverse kinematics. Additionally, through trajectory tracking experiments, it is verified that the modeling method is both rapid and accurate, making it suitable for real‐time applications. To showcase a practical application, the joint and its models are utilized as a force feedback origami joystick, designed for intuitive drone control. This joystick offers an enhanced control experience and conveys crucial information about collisions and external forces to drone operators. Overall, the data‐driven modeling approach introduces a new possibility of designing controllable compliant interfaces.","url":"https://doi.org/10.1002/aisy.202400217","authors":["Mustafa Mete","Alexander Schüßler","Yves Martin des Taillades","Bruno Trivelli","Jamie Paik"],"tags":["Joystick","Kinematics","Inverse kinematics","Computer science","Robot"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2024-11-20","doi":"https://doi.org/10.1002/aisy.202400217","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4390702829","name":"Towards an Integrative Framework for Robot Personality Research","source":"openalex","abstract":"Within human-robot interaction (HRI), research on robot personality has largely drawn on trait theories and models, such as the Big Five and OCEAN. We argue that reliance on trait models in HRI has led to a limited understanding of robot personality as a question of stable traits that can be designed into a robot plus how humans with certain traits respond to particular robots. However, trait-based approaches exist alongside other ways of understanding personality, including approaches focusing on more dynamic constructs such as adaptations and narratives. We suggest that a deep understanding of robot personality is only possible through a cross-disciplinary effort to integrate these different approaches. We propose an Integrative Framework for Robot Personality Research (IF), wherein robot personality is defined not as a property of the robot, nor of the human perceiving the robot, but as a complex assemblage of components at the intersection of robot design and human factors. With the IF, we aim to establish a common theoretical grounding for robot personality research that incorporates personality constructs beyond traits and treats these constructs as complementary and fundamentally interdependent.","url":"https://doi.org/10.1145/3640010","authors":["Anna Dobrosovestnova","Tim Reinboth","Astrid Weiss"],"tags":["Psychology","Personality","Robot","Human–computer interaction","Computer science"],"confidence":0.72,"sites":["robot-parts"],"publishedDate":"2024-01-10","doi":"https://doi.org/10.1145/3640010","addedAt":"2026-08-31T14:44:54.031Z","updatedAt":"2026-08-31T14:44:54.031Z"},{"id":"oa:W4409119878","name":"An Ultra‐Fast Rolling Double‐Helical Robot Driven by Constant Humidity","source":"openalex","abstract":"Abstract Untethered soft robots made of stimuli‐responsive materials hold great application potential in various fields. However, most robots of this type require artificial modulation of the stimuli to actuate, while it is a great challenge to achieve fast periodic locomotion under a constant external environment. Here, a double‐helical robot constructed with humidity‐sensitive agarose (AG) films, referred to as the Dualicalbot is proposed, which can rapidly roll under a constant humid environment by making two helices alternately bend by absorbing humidity to actuate the robot in two half‐cycles. A theoretical model is built to unveil the periodic deformation of the robot as well as the correlation between the design parameters and the motion speed, based on which the Dualicalbot can reach a maximum rolling speed of 5.8 BL s −1 . Moreover, it is capable of carrying a payload up to 100% of self‐weight and detecting the acid environment it rolls through.
