About

Ji-wung Choi is a leading researcher in autonomous mobile robotics, with a primary focus on real-time path planning, obstacle avoidance, and trajectory generation for non-holonomic and omnidirectional vehicles. His work bridges the gap between theoretical motion planning and practical, computationally efficient algorithms for semi-structured environments. Choi’s most influential contribution is his constrained global path optimization algorithm for articulated steering vehicles (2015, 51 citations), which introduced a two-step approach combining offline feasible motion primitives with online obstacle detection. He is also widely recognized for pioneering the use of Bézier curves and Voronoi diagrams to generate smooth, collision-free paths in real time, as demonstrated in his highly cited 2010 paper on mobile robot navigation (26 citations). His research has been instrumental in advancing autonomous navigation for wheeled robots, addressing key challenges such as local minima in potential field methods and the control of omnidirectional platforms. Beyond ground robotics, Choi has contributed to aerospace applications, including control system design for a Mars flyer concept. With a career spanning over a decade, his algorithms remain foundational for students and engineers developing safe, efficient autonomous systems.
