About

Shigeki Hatae is a pioneering figure in the development of advanced robotic actuation and precision manipulation systems. His research centers on the design and application of ultrasonic motors, particularly the novel multi-degree of freedom spherical ultrasonic motor, which he introduced in his highly influential 1991 paper (25 citations). This groundbreaking work proposed a compact actuator capable of multi-axis motion in a single joint, with potential applications ranging from robotic manipulators to laser cutting and assembly machines. Hatae further advanced this field by developing specialized stators for ultrasonic motor-based robotic actuators, as detailed in his 1992 work (5 citations). In parallel, he made significant contributions to kinematic calibration for industrial robots, notably the SCARA robot. His 1991 and 1992 papers (4 and 3 citations, respectively) introduced a novel calibration method combining condition number optimization with an error map technique, enabling more precise identification of geometric parameters and compensation of mechanical errors. Through these innovations, Hatae has left a lasting impact on both the theoretical foundations and practical implementation of high-precision, dexterous robotic systems.
