About
Sadayuki Ueha is a pioneering researcher in the field of ultrasonic motor technology and its applications in advanced robotics. His work has centered on the development and refinement of multi-degree-of-freedom (multi-DOF) piezoelectric ultrasonic motors — compact, silent actuators capable of generating high torque across multiple rotational axes — making them uniquely suited for next-generation robotic systems. Ueha's most significant contributions lie in translating this motor technology into practical robotic hardware, particularly articulated robot fingers and teleoperated systems. His 2011 paper on hybrid multi-DOF piezoelectric ultrasonic motors driving robot finger joints stands as his most influential work, accumulating 64 citations, while his earlier 2005 study applying multi-DOF ultrasonic servomotors to an auditory tele-existence robot demonstrated the technology's real-world versatility with 38 citations. His research also addressed critical engineering challenges such as miniaturization and preloading mechanisms, pushing the boundaries of what compact robotic joints can achieve. Collectively, Ueha's body of work has laid important groundwork for human-friendly robotic motion systems, influencing researchers working at the intersection of piezoelectric actuation, robotics design, and medical and industrial automation.
