Abstract

An agent with constant speed unicycle kinematics senses only the bearing towards a target and pursues it, guided by a steering control law proportional to the bearing-angle to the target. The target's speed is equal to that of the chasing agent while it moves at a constant velocity. This letter presents a comprehensive analysis of this unicycle pursuit problem and shows that with enough gain in the control law, the agent eventually either captures the target or follows its path while maintaining a finite distance from it, regardless of the initial conditions.
