Abstract

Deals with the posture stabilization problem of car-like mobile robots. For a long distance, path-planning should be done first. But, over a short distance like a parking maneuver, path planning is difficult since car-like mobile robots, different from the conventional differential drive mobile robot, have a limit on turning radius. The derivation of a control law is also difficult in the sense that there exists no smooth feedback control for this problem. We propose a simple and efficient algorithm for the problem with stability analysis. Using this algorithm, we can control a car-like mobile robot to move to a desired posture within a prescribed boundary. The performance is verified through simulations and experiments using a car-like mobile robot.
