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

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
