Abstract: One embodiment provides an apparatus that includes a plurality of wheels configured to rotate in either of two rotational directions about an axis of rotation. The apparatus further includes a turret portion disposed between the two wheels and rotatable about the axis of rotation in either of the two rotational directions and independently of the plurality of wheels. Additionally, the apparatus includes a motor configured to provide torque to the plurality of wheels and the turret portion. The motor can cause each of the plurality of wheels to rotate independently in either of the two rotational directions when operating in a first rotational speed mode. The motor can also cause the turret portion to rotate in either of the two rotational directions independently of the plurality of wheels when operating in a second rotational speed mode which is faster relative to the first rotational speed mode.
