An omnidirectional motorized wheelchair having front wheels consisting of a pair of free wheels, and rear wheels consisting of motor-operated wheels driven by electric motors independently of each other. This wheelchair can be moved forward and backward, turned to right and left, and turned in a fixed position. The motor-operated wheels are moved pivotally in the opposite directions by a steering unit to set these wheels to face in the lateral direction with respect to the rider. Thus, the wheelchair can be moved in the lateral direction with the rider facing forward, and it can also be turned while it is moved in the lateral direction. |
