About

Junhong Ha’s research focuses on robotics and control theory, particularly addressing foundational challenges in motion planning and collision avoidance. His most influential work, “A solution to the two-dimensional findpath problem” (1998, 18 citations), tackles the classic robotics “findpath problem”—navigating a moving solid among obstacles. Ha proposes a novel solution for the two-dimensional case, where two point masses must simultaneously reach designated targets while avoiding collisions, a critical advance for multi-agent systems. Earlier, in “Collision avoidance in a two-point system via Liapunov’s second method” (1995, 9 citations), he applied Liapunov’s stability theory to guarantee safe trajectories, demonstrating a rigorous mathematical approach to real-time obstacle avoidance. Though his citation counts are modest, Ha’s work is notable for bridging theoretical control methods with practical path-planning problems, offering early insights that underpin modern autonomous navigation. His contributions remain relevant for researchers exploring multi-robot coordination and safety-critical motion planning.
