About

Yoon Haeng Lee is a robotics researcher whose work spans mobile robotics, legged locomotion, and advanced actuator design. His research career reflects a consistent focus on solving fundamental engineering challenges in robot mobility — from unconventional climbing platforms to sophisticated quadrupedal systems capable of dynamic, animal-like movement. Lee's early breakthrough came with his development of an impeller-based wall-climbing robot (2013, 72 citations), which demonstrated a novel adhesion mechanism enabling robots to traverse vertical surfaces. He subsequently turned his attention to quadrupedal robotics, making significant contributions to gait control through biologically inspired strategies, including central pattern generator frameworks and recurrent neural networks for reflexive locomotion. His series of gait transition and obstacle-avoidance studies established a coherent foundation for robust legged robot navigation. A particularly notable thread in Lee's work is his advancement of torque-controllable actuator technology. His embedded torque sensor module (2018, 35 citations) and the modular actuator unit underpinning his quadruped platform (2020, 48 citations) represent meaningful hardware contributions to precision robotic joint control. His whole-body control frameworks, incorporating angular momentum regulation for stair climbing and dynamic stability, demonstrate his ability to integrate mechanical and algorithmic innovations into complete robotic systems.
