About

Hyung Jik Lee is a robotics researcher whose work centers on mobile robot systems, human-robot interaction, and intelligent control mechanisms. His research is particularly distinguished by its focus on designing robotic platforms that meaningfully assist human users, including elderly and physically limited individuals. Lee's most recognized contribution is his development of guidance and force-control frameworks for wheeled mobile robots, enabling intuitive human-directed navigation through applied force sensing. His 2010 paper on this topic has accumulated 16 citations, reflecting its influence in the human-robot interaction community. Complementing this, Lee pioneered the "TransBot" system — a mobile inverted pendulum robot capable of carrying a human operator — demonstrating both the engineering feasibility and practical promise of balancing-robot technology as a personal transportation vehicle. This work, cited 11 times, represents a meaningful step toward accessible, self-balancing mobility aids. His earlier 2008 study laid foundational groundwork for force-controlled carrier robots, employing impedance filtering to translate human-applied forces into responsive robot motion. Collectively, Lee's research bridges control theory and assistive technology, making tangible contributions to the development of robots that safely and intuitively collaborate with human users in real-world environments.
