About

Liqiang Feng is a pioneering researcher in mobile robotics, with foundational contributions to robot localization, odometry error correction, and autonomous navigation that have shaped the field for decades. His most celebrated work, "Measurement and Correction of Systematic Odometry Errors in Mobile Robots" (1996), has accumulated nearly 800 citations and remains a landmark reference, providing practical, rigorous methods for identifying and reducing the kinematic imperfections that degrade the positional accuracy of differential-drive robots. Complementing this, his co-authored survey "Navigating Mobile Robots: Systems and Techniques" (1996, 595 citations) offered the research community a comprehensive taxonomy of relative and absolute positioning strategies, becoming an essential introductory resource for students and practitioners alike. His development of UMBmark, a standardized benchmark for quantifying odometry errors, gave the community a common measurement framework still referenced today. Beyond localization, Feng extended his expertise to practical navigation challenges, including ultrasonic-based obstacle avoidance in confined warehouse aisles and vision-based navigation techniques. His later work on embedded Linux control systems for inspection robots demonstrates a career-spanning commitment to translating theoretical advances into deployable robotic systems. Altogether, his research has profoundly influenced how mobile robots perceive, calibrate, and navigate their environments.
