Abstract: A drive assembly is provided and includes a rotatable housing, a motor disposed within and to rotate with the housing, the motor including a drive element and first and second drive shafts, which are independently rotatably drivable by the drive element, a first drivable element coupled to the first drive shaft such that rotation thereof is transmitted to the first drivable element and configured to propel the housing in a first direction during first drive shaft rotation and a second drivable element coupled to the second drive shaft such that rotation thereof is transmitted to the second drivable element and configured to propel the motor in a second direction, which is transversely oriented relative to the first direction, relative to the housing during second drive shaft rotation.
