About

Shigeru Sugitani is a pioneering figure in the field of precision robotics and actuator design, with a primary focus on ultrasonic motor technology. His most significant contribution lies in the development of multi-degree-of-freedom spherical ultrasonic motors, a breakthrough that enables compact, highly controllable motion for robotic manipulators. His landmark 2002 paper, "Multi degree of freedom spherical ultrasonic motor," which has garnered 69 citations, details the successful creation of two prototypical spherical motors, each offering exceptional controllability for driving a spherical rotor. This work builds upon his earlier foundational research from 1995, where he first introduced the concept of applying ultrasonic motors to dexterous robotic arms, a paper that has received 11 citations. Sugitani’s innovations are critical for advancing intelligent robots capable of replicating complex human arm tasks, offering a quieter, more precise, and more compact alternative to traditional electromagnetic actuators. His research remains highly influential for engineers and researchers developing next-generation manipulators and haptic devices.
