ABSTRACT:
An automatic guided vehicle having three wheels consisting a front wheel and a pair of rear wheels and being capable of travelling along a track formed on a floor by a white line or aluminum foil while detecting the track by means of an optical type track sensor. The front wheel of this vehicle can be turned relative to a main body of the vehicle in response to a steering operation and can be locked in the lateral direction. The position of the pair of rear wheels can be symmetrically changed from a paralleled state to an orthogonal state relative to the center line of the main body to be maintained in these states, thereby enabling the main body to turn or laterally travel with radii of gyration determined in accordance with turning angles of the rear wheels relative to the main body on the basis of the relative turning and driving operations of the front and rear wheels.
