Continuously Variable Transmission and Stiffness Actuator Based on Actively Variable Four-Bar Linkage for Highly Dynamic Robot Systems

RA-L 2024

This letter presents a novel actuation mechanism that combines a continuously variable transmission (CVT) mechanism with a variable stiffness actuator (VSA) for highly dynamic robot systems such as legged robots. The CVT effectively changes the input-output transmission ratio of the system, thereby

Magnetic Gear-Based Actuator: A Framework of Design, Optimization, and Disturbance Observer-Based Torque Control

RA-L 2023

This letter presents a design framework and novel control strategy for a compact coaxial magnetic-gear-based actuation module suitable for small-to-mid-sized mechanical and robotic applications. The proposed actuation module adopts a non-contact magnetic coupling mechanism to transmit rotational pow

Mechanical Variable Magnetic Gear Transmission: Concept and Preliminary Research

RA-L 2022

This letter presents a novel concept of a <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">non-contact</i> variable transmission mechanism using a coaxial magnetic gear. Conventional variable transmissions have provided a function of a robust transmis
