Flexible electronic devices offer the capability to integrate and adapt with human body. These devices are mountable on surfaces with various shapes, which allow us to attach them to clothes or directly onto the body. This paper suggests a facile fabrication strategy via electrospinning to develop a stretchable, and sensitive poly (vinylidene fluoride) nanofibrous strain sensor for human motion...

This paper presents the design and analysis of a novel variable-stiffness robotic gripper, RobInLab VS gripper. The purpose is to have gripper that strong reliable as rigid grippers but adaptable soft grippers. achieved by designing modular fingers combine jamming material core with an external structure, made flexible materials. allows finger softly adapt object shapes when capsule not active,...

Replication of human hand motions on anthropomorphic robotic hands is typically treated in literature as the combination two sub-problems: measurement motions, and mapping such hand. In this letter we focus second one. Different approaches have been proposed to deal with problem, but none them preserves both master finger shapes fingertip positions hand, i.e. ensuring predictability natural mot...

This study developed a soft pneumatic glove actuated by elliptical cross-sectional guided bending bellows to augment finger-knuckle rehabilitation for patients with hand dysfunction. The actuators (GBBAs) are made of thermoplastic elastomer (TPE) materials, demonstrating the necessary air tightness as actuator. GBBAs could produce different moments inertia when increasing internal pressure driv...

In this paper, a new biomimetic tendon-driven actuation system for prosthetic and wearable robotic hand applications is presented. It is based on the combination of compliant tendon cables and one-way shape memory alloy (SMA) wires that form a set of agonist–antagonist artificial muscle pairs for the required flexion/extension or abduction/adduction of the finger joints. The performance of the ...

Here, we present the design, fabrication, and evaluation of a prismatic-revolute-revolute joint hand called the model B that we developed for grasping from ungrounded vehicles. This hand relies on a prismatic proximal joint followed by revolute distal joints in each finger and is actuated by a single motorand a tendon-based underactuated transmission. We evaluate this design’s grasping capabili...

This research presents a multi-fingered hand and computer control system intended for research in dextrous manipulation. The hand mechanism is based on an anthropomorphic configuration with four identical fingers. Each finger has four degrees of freedom actuated by four dc servomotors. The fingers, palm, and mechanical interface to a robotic arm are separate components of a modular design allow...

Robotic hands built for manipulation are often anthropomorphic but not anatomically accurate. We are constructing an anatomically-correct testbed (ACT) of the human hand to understand its mechanisms, function, and control. We have previously demonstrated that an accurate model of the extensor mechanism in the ACT Hand is crucial in realizing the human-like finger movements. Here, we present des...

conclusions rtesd in the prone position is safe and presents a feasible alternative for management of large rectal tumors. we also anticipate the technique to further improve with the advancement of robotic technology. introduction endoscopic submucosal dissection (esd) of large tumors of the rectum is particularly challenging using colonoscopy or with laparoscopic instruments. more recently ro...

Evolution gave humans advanced grasping capabilities combining an adaptive hand with efficient control. Grasping motions can quickly be adapted if the object moves or deforms. Soft-grasping anthropomorphic is a great capability for robots interacting objects shaped humans. Nevertheless, most robotic applications use vacuum, 2-finger custom made grippers. We present biologically inspired spiking...
