About

Namkon Lee is a pioneering researcher in the field of medical robotics, with a primary focus on the design and control of capsule robots—miniature, self-propelled devices intended for non-invasive medical procedures such as endoscopy. Lee’s major contributions center on the Capsubot, a novel two-mass system that moves bidirectionally without any external moving parts, making it uniquely suited for small-scale construction and internal medical applications. In his most-cited work, “Control system design and experimental verification of Capsubot” (2008, 12 citations), Lee demonstrated the fundamental locomotion principles and control strategies that enable this robot to navigate confined spaces. He further advanced the field with “Positioning control of a capsule robot using sliding mode control” (2009, 8 citations), where he applied robust sliding mode control to achieve precise positioning—a critical requirement for surgical tasks. Lee’s research has laid essential groundwork for the development of safer, more effective endoscopic tools, with his work being cited by subsequent studies in medical robotics and control systems. His achievements highlight a commitment to translating theoretical control designs into practical, life-saving technologies.
