Apparatus, Applications and Method of Wearable Mobility Assistance Robot

An apparatus includes at least one supernumerary artificial limb and a base structure configured to couple with a human body. The base structure includes a sensor that obtains a measurement regarding load of the human body. The proximal end of the supernumerary artificial limb is coupled to the base structure. The apparatus further includes a processor operatively coupled with the sensor and configured to receive the measurement from the sensor. The processor is also configured to generate a control signal to change at least one of a position of the supernumerary artificial limb and a torque exerted by the supernumerary artificial limb based on the measurement regarding the load.
