Abstract
An omnidirectional rotation drive device includes a knuckle connected to a vehicle body, a wheel body configured to rotate around the knuckle, a plurality of sub-wheel units rotatably supported on the wheel body, and a bevel gear located in the wheel body and configured to rotate around the knuckle. The plurality of sub-wheel units is rotated depending on a difference between an angular speed of the wheel body and an angular speed of the bevel gear.
