A Palm-Sized Omnidirectional Mobile Robot Driven by 2-DOF Torus Wheels

Yunosuke Sato, Ayato Kanada, Tomoaki Mashimo

RA-L 2023

This letter proposes a palm-sized omnidirectional mobile robot with two torus wheels. A single torus wheel is made of an elastic elongated coil spring in which the two ends of the coil connected each other and is driven by a piezoelectric actuator (stator) that can generate 2-degrees-of-freedom (axi

Self-Sensing and Feedback Control for a Twin Coil Spring-Based Flexible Ultrasonic Motor

Yunosuke Sato, Ayato Kanada, Tomoaki Mashimo

RA-L 2020

We propose a twin coil spring-based soft actuator that can move forward and backward with extensibility and can bend left and right with flexibility. It is driven by two flexible ultrasonic motors, each consisting of a compact metallic stator and an elastic elongated coil spring. The position of the
