By combining two the motion of two-wheel the vehicle can move in the direction of the perpendicular wheel, or, by rotating all the wheels in the same direction, the vehicle can rotate in place. By using the resultant motion of the vector addition of the wheels a Killough platform is able to achieve omni-directional motion. [2]
