About

In-Hwan Choi is a robotics researcher whose work spans cooperative multi-agent systems, mobile robot control, and autonomous navigation. His most influential contribution, a 1997 paper on distributed control architecture for cooperative multi-agent systems applied to soccer robots, has garnered 41 citations and remains a foundational reference for researchers designing decentralized robotic coordination frameworks. This pioneering work demonstrated the practical viability of real-time multi-agent cooperation in dynamic, competitive environments. Choi's research further extended into motion control, where his 2002 work on sliding mode control for nonholonomic wheeled mobile robots offered a mathematically rigorous approach to trajectory tracking using variable structure systems and polar coordinate representation — earning 23 citations and contributing meaningfully to robust control theory for mobile platforms. His later investigations shifted toward perception and autonomy, with 3D vision-based obstacle avoidance for humanoid robots and sensor-fusion strategies combining infrared and image data for multi-agent navigation in unknown environments. Together, these works reflect a coherent research trajectory — from system-level coordination to low-level control and perceptual intelligence — making Choi a notable contributor to the field of autonomous and cooperative robotics.
