Abstract

The invention relates with the omni-directional toy vehicle that can move in all directions of forward, backward, rotational, left and right movement by driving manually the omni-directional wheels installed at the vehicle and combining their rotational directions. The vehicle characterized by comprising a frame composing the body of the vehicle, at least three rotating axles which are installed at the lower part of the frame with a rotatable mechanism, at least three omni-directional wheels which are connected to the axles, at least three driving element which are connected to the axles and drive the omni-directional wheels and a seat located at the upper part of the frame. The vehicle can be driven and steered simultaneously by means of driving combinations of each omni-directional wheel without any additional steering element and make an operator be interested in the manual operation of omni-directional wheels.
