AUTOMATIC OPERATION UNMANNED VEHICLE

PURPOSE:To improve the tracking performance with respect to a running track by providing a traveling path detection sensor before and after front and rear wheels and using the traveling path detection sensor toward each progressing direction of the front and rear wheels so as to read the traveling track thereby applying steering. CONSTITUTION:Front wheel traveling path detection sensors 11, 12 are arranged before and after the front wheel 1 and rear wheel side traveling path detection sensors 13, 14 are arranged before and after the rear wheel 2. In the case of the forward traveling, the sensors 11, 13 send a signal to a front wheel drive motor and the rear wheel steering motor while detecting the difference between the traveling track read tape 5 and the optical reflection on the floor 6 to apply both when drive traveling along the tape 5. In the case of the backward drive, the sensors 12, 14 apply both wheel drive traveling similarly as the forward drive. Thus, very excellent tracking performance is attained with the unmanned vehicle without fallen out of the traveling track.
