About

Kwun-Lon Ting is a mechanical engineering researcher whose work has profoundly shaped our understanding of kinematic analysis, mechanism design, and robotic systems. His research spans three interconnected domains: joint clearance uncertainty in linkages and manipulators, parallel manipulator design and analysis, and rotatability theory for complex mechanical systems. Ting's most influential contribution lies in characterizing how manufacturing imperfections — specifically joint clearances — propagate into positional uncertainty in planar and spatial robotic systems. His foundational 2000 paper on this topic has accumulated 125 citations, establishing him as a leading authority in tolerance and uncertainty analysis for mechanisms. Building on his celebrated N-bar rotatability laws, Ting developed elegant geometric models that allow engineers to evaluate positional error across multiple-loop linkages and parallel manipulators, work he continued refining into 2017. Beyond uncertainty analysis, Ting has contributed to the synthesis and analysis of novel parallel manipulators, including a spatial 3-DOF 2T1R-type manipulator and a seven-bar spherical parallel manipulator, advancing practical robotics applications such as robot wrists and camera-orienting devices. His tribute to the late Dr. Atmaram H. Soni also reflects his deep connection to the mechanisms research community. Collectively, Ting's work provides indispensable tools for designing more precise and reliable robotic systems.
