About

Kwan-Hee Lee is a robotics researcher whose work focuses on motion planning, collision avoidance, and the automation of heavy industrial machinery. His key contributions lie in developing geometric algorithms for robot path planning and solving complex kinematic problems for large-scale equipment. Lee’s most cited paper, "Motion planning with planar geometric models" (2002, 12 citations), presents algebraic algorithms that decompose collision-free space into connectivity graphs, enabling efficient path planning for robots operating in planar environments. This foundational work addresses the global topological structure of obstacle avoidance. Lee has also made significant contributions to the automation of reclaimers—massive machines used in raw ore yards to dig and transfer material to blast furnaces. His papers "Inverse kinematics of a reclaimer: redundancy and solution" (2002, 4 citations) and "Approximation of Optimal Moving Paths of Huge Robot Reclaimer with a 3D Range Finder" (2006, 6 citations) present methods for solving inverse kinematics and detecting stockpile shapes using 3D range finders. These achievements demonstrate Lee’s impact on industrial robotics, bridging theoretical motion planning with practical applications in heavy machinery automation.
