About

Hosang Lee is a robotics researcher whose work spans bipedal locomotion, assistive robotics, and human-robot interaction. His key research areas include reactive walking control for biped robots, exoskeleton design for joint assistance, and socially assistive robots for elderly care. Lee’s major contributions include developing an event-based finite state machine (FSM) for biped robots that enables rapid reactions to unforeseen disturbances—a critical step toward robust real-world walking (18 citations). He also designed a novel controller for nonanthropomorphic exoskeletons that reduces operator joint torque through contact force generation (5 citations), and contributed to Team SNU’s strategies in the DARPA Robotics Challenge Finals 2015 (5 citations). Notably, Lee led a study on the socially assistive robot Hyodol, demonstrating significant reductions in depressive symptoms and improvements in quality of life among community-dwelling older adults (15 citations). His work on contact-consistent disturbance observers for floating-base robots (4 citations) and operational space control under actuator bandwidth limitations (3 citations) further showcases his expertise in robust control. Lee’s research bridges fundamental robotics challenges with impactful applications in healthcare and assistive technology.
