Researchers propose a coil spring-based soft actuator using two flexible ultrasonic motors
Researchers Yunosuke Sato, Ayato Kanada, and Tomoaki Mashimo have developed a novel continuum (snake) robot actuator that can flex and sense its position with twin coil spring assemblies. Each uses a couple of piezoelectric actuators to induce ultrasonic vibrations on a stator block, pushing the spring inside forwards or backwards. When combined, the springs can advance […]
