About
Kaiji Sato’s research bridges precision motion control and assistive robotics, with a focus on pneumatic artificial muscles (PAMs) and harmonic drive mechanisms. His foundational work on harmonic speed reducers—compact, backlash-free gears essential for precision robots—established dynamic models and disturbance-observer-based control strategies that enable high-accuracy rotational positioning (14 citations). Expanding into soft actuation, Sato developed precise positioning systems for PAMs, leveraging their high power-to-weight ratio and inherent safety for applications in bionic robots and rehabilitation devices (17 citations). His characterization of opposing-pair PAM configurations further advanced biomimetic actuator design. More recently, Sato has addressed the growing demand for elderly care robots, creating a standing, walking, and sitting support robot that estimates user state from minimal sensors (12 citations). He also proposed a human link model to generate training data for state estimation, reducing reliance on costly sensor arrays (2 citations). With over 60 citations across his most influential papers, Sato’s work uniquely combines rigorous dynamic analysis with practical, human-centered robotics—making him a key figure in precision mechatronics and assistive technology.
