Abstract

Shape memory alloy (SMA) shows promise as a powerful actuator for soft robots, offering high force and a simple mechatronic setup. However, effectively controlling SMA-actuated soft robots remains challenging. This study presents a modular robot design that leverages a curved beam's snap-through mechanics and an integrated ``mechanical'' circuit. This design enables robotic locomotion with only a single DC power supply, representing a notable advancement toward SMA-actuated, controller-free locomotion.
