Tsong‐Li Lee

About

Tsong-Li Lee is a robotics researcher whose work has made meaningful contributions to the fields of mobile robot navigation, autonomous motion planning, and robot localization. His research is most prominently centered on applying fuzzy logic to the challenges of robot autonomy, most notably demonstrated in his highly cited 2003 paper "Fuzzy Motion Planning of Mobile Robots in Unknown Environments," which has accumulated 79 citations and remains his landmark contribution to the field. Building on this foundation, Lee extended fuzzy methodologies to multi-robot soccer systems and refined navigation algorithms for robots operating in completely unknown environments, equipping them with ultrasonic sensors, electronic compasses, and dead-reckoning systems. Beyond fuzzy approaches, Lee has explored optimal control theory, developing nonlinear programming methods for time-optimal control of omni-directional mobile robots — a departure from conventional Pontryagin's Minimum Principle techniques. His work also spans robot localization, employing laser range finders, particle swarm optimization, and visual information from CCD cameras to achieve precise 3D positioning. Collectively, his publications reflect a researcher dedicated to bridging theoretical control methods with practical autonomous systems, offering graduate students and engineers a valuable body of work for understanding sensor-based robot intelligence.
