About

Bum-Joo Lee is a robotics researcher whose work spans humanoid robot locomotion, kinematic calibration, and advanced robotic systems. He has made particularly significant contributions to the precision and reliability of robot manipulators, developing novel laser-based and geometrically derived differential kinematics techniques for calibrating kinematic parameters — works that have garnered 109 and 96 citations respectively, reflecting their substantial influence on robot accuracy research. His calibration methodologies address the inevitable manufacturing discrepancies between designed and physical manipulators, offering systematic solutions that have become widely referenced in the field. Lee has also been a leading voice in humanoid robot walking, proposing adaptive algorithms that allow robots to modulate gait parameters such as step length, walking period, and direction — even on inclined surfaces — while maintaining dynamic stability through zero moment point analysis. His landing force control work, utilizing time-domain passivity approaches, further demonstrates his commitment to stable, real-world humanoid locomotion. He contributed to the development of the HanSaRam humanoid robot platform and has explored interdisciplinary applications ranging from structural health monitoring robotics to expressive violin-playing robots. Collectively, his research reflects a career dedicated to bridging theoretical robotics with practical, embodied performance.
