Abstract
An input device (such as a rotational hand crank) receives a constantly-applied motion, and outputs a signal to a controller which, in turn, sends an appropriate signal to an electric motor, which is connected to the chair via a mechanical transmission. The wheel is removably mounted in front of a wheelchair such that the front wheels of the chair are lifted above the ground. The device is generally steered manually, such as by pivoting an input device to one side.
