ABSTRACT:
Disclosed is a powered wheel chair with individual motors driving each of two separate drive wheels. The motors are controlled by the amount of torque applied to the handrim of the driving wheel. If the operator pushes on the handrim of the drive wheel, as is well known, the torque created by such movement is sensed and activates the drive motor to cause the drive wheel to rotate. The power applied to the drive motor is controlled by the amount of torque applied to the handrim such that the conventional control of the wheel chair is maintained.
