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.

[ I claim:] [1.] Wheeled vehicle which automatically changes travel direction when it meets an obstacle, this device being provided with two independent front-wheel drives and comprising:two obstacle-detection units located on the front of the vehicle at each side,means of transmission for each driving wheel from a motor shaft, through means for reversing the direction of rotation,means of connection placed between each obstacle-detection unit and means of transmission for the driving wheel located on the opposite side,said obstacle-detection units and said means of connection arranged in such a manner that, when the vehicle meets an obstacle, the means of detection actuated by said obstacle act, through said corresponding means of connection, so as to actuate said means for reversing the direction of rotation, and to have the rotation of the driving wheel pass from the forward direction to the rear direction,each obstacle-detection unit comprising an elongated unit constituted by the front edge, extending practically on a half-width and on the corresponding angle of the front of the vehicle which is opposite to the driving wheel with which said unit is functionally associated, an arm shaped in such manner that its opposite end is practically located in the area of the driving wheel that it controls and is supported at free rotation on a revolving axle practically vertical, and said extended unit is coupled in a selective manner to the motor shaft driving said driving wheel through the aforementioned connection means.
