About

Eun-Seok Choi’s research bridges the foundational theory of robotics with immersive human-robot interaction, focusing on the stability and control of complex robotic systems. His most influential work addresses the challenging problem of stabilizing robot manipulators with flexible joints and uncertain parameters, particularly those actuated by DC motors with flexible coupling shafts. In his 2002 paper, he proposed a linear output-based controller that ensures local exponential stability despite system uncertainties, a contribution that has garnered 9 citations for its practical implications in precision robotics. Earlier, in 2000, Choi explored the structural properties of flexible-joint robot models with output controllers, demonstrating that global asymptotic stability does not guarantee local exponential stability—a key insight for robust controller design. This work, with 6 citations, has informed subsequent research in nonlinear control theory. More recently, Choi has expanded into telepresence and social robotics, as seen in his 2016 paper “Be closer as you being there,” which integrates HMD-controlled stereoscopic cameras with interactive virtual messaging for immersive remote experiences. This system, originally designed for mobile robot control, showcases his ability to translate control theory into user-centered applications, reflecting a career dedicated to both rigorous analysis and innovative human-robot interaction.
