About

Tok‐Son Choe is a robotics researcher whose work centers on autonomous navigation, collision avoidance, and real-time path planning for mobile robots. His most influential contribution is the development of a model predictive control (MPC) framework for obstacle avoidance in unknown environments, a paper that has garnered 11 citations and remains a foundational reference in the field. Choe also pioneered the one-dimensional virtual force field (1D-VFF) algorithm, a novel approach for reflexive local path planning that simplifies traditional force-field methods while maintaining real-time performance. This work, cited 6 times, offers an elegant solution for robots needing to react swiftly to dynamic obstacles. Additionally, his research on distributed model predictive collision avoidance addresses the critical challenge of multi-robot coordination, enabling car-like robots to navigate safely by sharing information online within a constrained optimization framework. Choe’s contributions are particularly notable for bridging theoretical control strategies with practical, implementable algorithms, making his work valuable for both academic researchers and engineers developing autonomous systems. His focus on reflexive, real-time solutions continues to influence modern approaches to mobile robot safety and efficiency.
