A wheel module is configured for use on a vehicle chassis. A drivable
vehicle includes a wheel module operatively connected to a vehicle
chassis. The wheel module includes at least one non-rotating structural
unit, a rotatable wheel controllably connected to the structural unit, a
vehicle attachment interface operatively connected to the non-rotating
structural unit including a load-bearing vehicle retention coupling and a
control signal receiver. The wheel module further includes chassis
components including at least one of a brake system, steering system,
motor and suspension system operatively connected to the non-rotating
structural unit and to the wheel, and operatively connected to the
control signal receiver for controlling the wheel in response to
non-mechanical control signals received through the control signal
receiver.
