Abstract:

A moving target tracking and obstacle avoidance control system for unicycle mobile robots is proposed in this paper.The control system consists of two nested loops.Tracking law in the inner loop controls the robot to track the target via reducing the posture error to zero and its stability is analyzed using Lyapunov function method.The law also takes into account of the velocity limit of the robot.

Key words: mobile , robot,  , target , tracking,  , impedance , control,  , obstacle , avoidance
