About

Y. L. Zhang is a pioneering figure in mobile robotics, best known for foundational contributions to the tracking control of wheeled mobile robots. Their seminal 1997 work, “On the Tracking Control of Differentially Steered Wheeled Mobile Robots,” remains a cornerstone reference with 31 citations, establishing core algorithms for analyzing the kinematics of differentially steered platforms. Zhang’s research systematically addressed critical challenges in robotic motion, including tracking variable assignment, singularity analysis, and position-orientation trajectory control—problems that underpin modern autonomous navigation systems. By rigorously modeling the inherent kinematic constraints of two-wheeled differential drives, Zhang provided essential theoretical frameworks that have enabled subsequent advances in mobile robot path following and stability. This work has influenced generations of robotics engineers and researchers working on everything from warehouse automation to service robots. Zhang’s clear exposition of tracking singularities and practical control strategies continues to be cited as a fundamental reference in robotics curricula and applied research, cementing their legacy as a key architect of mobile robot control theory.
