Abstract

See full text

A motorized door opening device, including

    at least one wheel, configured to be lowered to a surface and forced thereagainst with a force sufficient to ensure friction between the wheel and the surface and to prevent slipping of the wheel relative to the surface;an electric motor including a rotor coupled to rotate the wheel;a wheel actuator, coupled between the door and the wheel, to lower the wheel to the surface in response to a wheel lowering signal; and control circuitry to signal the wheel actuator to lower the wheel by generating the wheel lowering signal and push down the wheel to create friction; and a door attachment member to attach the motor and the wheel actuator to a bottom part of the door;whereby rotation of the wheel after lowering of the wheel causes the wheel to rotate in contact with the surface and move the door.
