Abstract: Mechanisms are disclosed for releasably attaching a wheel to a vehicle in a position where the wheel supports a weight of the vehicle. An illustrative quick connect system is described to include a wheel, a vehicle frame, and a coupling system that releasably attaches the wheel to the vehicle frame. The coupling system, when in a coupled state, may substantially prevent or oppose rotation between a wheel core and the vehicle frame.

Abstract: Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

Abstract: A system and a vehicle are described. An illustrative system includes a vacuum chamber and one or more components of a motor. The one or more components of the motor may be provided in the vacuum chamber and may be configured to move in a partial or complete vacuum created within the vacuum chamber.

Abstract: Vehicles are disclosed that are configured to carry loads in a stabilized manner, such that the load is maintained in a substantially constant position or orientation relative to a predetermined reference point or frame even as the vehicle moves. A stabilization controller in such a vehicle receives information about movement of the vehicle relative to the reference point or plane from one or more sensors on the vehicle, and uses the information to control one or more movable objects by which the load is secured to the vehicle so as to maintain a relatively constant relationship between the load and the reference point or plane.
