About

Sangkeum Lee is a pioneering figure in autonomous mobile robotics, with a focused expertise in motion control and trajectory tracking for wheeled systems. His most influential work, "A fast tracking error control method for an autonomous mobile robot" (1993), introduced a novel approach to minimizing positional deviations in differentially driven robots. By leveraging a wheel Jacobian to transform tracking errors into precise displacement changes for each drive wheel, Lee developed a computationally efficient control strategy that significantly improved real-time navigation accuracy. This foundational contribution, which has garnered 16 citations, addresses a critical challenge in robotics: ensuring that a robot faithfully follows a desired path despite dynamic disturbances. Lee’s method stands out for its speed and practicality, enabling smoother and more reliable autonomous operation. His research has implications for industrial automation, service robotics, and mobile platform design, offering a robust solution to error correction that remains relevant decades later. Through this work, Lee has established himself as a key contributor to the early development of agile, wheeled mobile robots, influencing subsequent advances in motion control and path-following algorithms.
