An omnidirectional wheel includes a hub, a number of wheels, and a number of rubber covers. The hub defines a shaft hole passing through the hub. Each of the wheels is rotationally mounted on the hub and spaced around the shaft hole. Each of the rubber covers is sleeved on a corresponding one of the wheels and includes a three-dimensional pattern. The rubber covers prevent the hub from directly contacting the ground.
