This work presents a control strategy that allows a follower robot to track a target vehicle moving along an unknown trajectory with  nknown velocity. It uses only artificial vision to establish both the robot's position and orientation relative to the target, so as to maintain a specified formation at a given distance. The control system is proved to be asymptotically stable at the equilibrium point, which corresponds to the navigation objective. Experimental results with two robots, a leader and a follower, are included to show the performance of the proposed vision-based tracking control system.a follower robot to track a target vehicle moving along an unknown trajectory with  nknown velocity.
