Abstract:
1. A stand-up wheelchair, comprising: a stand-up assembly having an articulated structure movable from a sitting configuration, a kneeling configuration, a reaching configuration, or a leaning configuration, to a substantially standing configuration, the stand-up assembly structured and dimensioned to support a passenger from a sitting position, a kneeling position, a reaching position, or a leaning position, to a substantially standing position; a plurality of rotatable members operable to frictionally interface the stand-up wheelchair to a travel surface and to move the stand-up wheelchair along the travel surface; a gyroscopic stabilization assembly having at least one gyroscope operable to apply a righting torque along an output axis of the stand-up wheelchair, the gyroscopic stabilization assembly including at least one rotor operable to pivot about a spin axis; and a dynamic stability controller operably coupled to the gyroscopic stabilization assembly, the dynamic stability controller operable to gimbal the at least one gyroscope about an input axis to apply the righting torque about the output axis responsive to a change in an externally applied torque.
