ABSTRACT:
Wheeled vehicle which automatically changes travel direction when it meets an obstacle and which includes two independent front driving wheels; two obstacle-detection units located on the front of the vehicle at each side; a transmission mechanism for each driving wheel from a motor shaft through a mechanism for reversing the direction of rotation; and a connection mechanism placed between each obstacle-detection unit and the transmission mechanism for each driving wheel located on the opposite side; the obstacle-detection units and connection mechanisms being arranged in such a manner that, when the vehicle meets an obstacle, the detection unit or units actuated by the obstacle act through the corresponding connection mechanisms so as to actuate the direction-reversing mechanism, and to have the rotation of the driving wheel pass from the forward direction to the rear direction.
