Hybrid Antagonistic System With Coiled Shape Memory Alloy and Twisted and Coiled Polymer Actuator for Lightweight Robotic Arm

RA-L 2022

Artificial muscles have been developed for various input power sources. Among them, thermally driven actuators can be easily actuated at a low voltage without an additional device using the Joule heating. Therefore, these actuators can be considered suitable for developing lightweight robots. Shape

Retractable Locking System Driven by Shape Memory Alloy Actuator for Lightweight Soft Robotic Application

RA-L 2022

Shape memory alloy actuators (SMA) are widely used in robots owing to their flexibility and light weight. However, there is a drawback in that SMAs need to be used as a bundle owing to their lower force density than the motor. In addition, SMAs require continuous current to maintain a contracted sta

Soft Fabric Actuator for Robotic Applications

IROS 2018poster

This paper presents a fabric actuator consisting of ordinary polymer fibers, conductive fibers, and twisted and coiled soft actuators (TCAs). Previous studies have developed a Spandex TCA (STCA) that is driven at a lower temperature than the conventional Nylon TCA and exhibits greater actuation stra…

Biomimetic robotic joint mechanism driven by soft linear actuators

ICRA 2017poster

From being soft, flexible and producing movement by contracting, soft linear actuators are said to have muscle-like properties. Due to these similarities, they are often called “artificial muscle actuator.” However, the strain produced by these actuators is generally insufficient to be utilized in a…
