About

Kok-Meng Lee is a pioneering figure in robotics and precision motion systems, best known for his groundbreaking work on multi-degree-of-freedom (DOF) actuation and sensing. His research centers on the design of spherical motors and encoders that enable compact, single-joint robotic wrists capable of three-DOF motion—a critical innovation for applications requiring high-speed, omnidirectional orientation control, such as robotic assembly, plasma cutting, and active joysticks. Lee’s most influential contribution is the development of a real-time optical sensor for simultaneous three-DOF measurement, detailed in his 2004 paper (108 citations), which addressed the limitations of conventional single-axis encoders in precision machining and optical tracking. His earlier work on the spherical stepper wrist motor (1988, 64 citations) laid the foundation for this technology, demonstrating a novel design that integrates actuation and sensing into a single joint. Lee’s impact is underscored by his sustained influence over decades, with his 2003 and 2004 papers collectively advancing the state of the art in spherical motion systems. His achievements have been instrumental in enabling more agile, precise, and compact robotic manipulators, making him a key reference for researchers in mechatronics and automation.
