Wheel module

A drivable vehicle comprising:

• a wheel module including:
• at least one non-rotating structural unit;
• a rotatable wheel controllably connected to said at least one non-rotating structural unit;
• a vehicle attachment interface operatively connected to said at least one non-rotating structural unit, the vehicle attachment interface including a load-bearing vehicle retention coupling and a control signal receiver;
• and
• chassis components including at least one of a brake system, steering system, motor and suspension system operatively connected to said at least one 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;
• and
• a vehicle chassis including a frame, at least one control unit operatively connected to the chassis components, a wheel module attachment interface including a control signal connector port and a load-bearing wheel module retention coupling operatively connected to the frame, wherein said at least one control unit is operatively connected to the control signal connector port;
• wherein the control signal receiver is operatively connected to the control signal connector port such that said at least one control unit is communicable with and controls the chassis components, and the load-bearing vehicle retention coupling is operatively connected to the load-bearing wheel module retention coupling.
