Foot-operated controller
A practical control device having up to eight independent channels of communication for simultaneously operating a plurality of electromechanical devices or for simultaneously performing a plurality of independent functions on an electromechanical device, such as a prosthetic hand, includes a foot-operated controller and a microprocessor. The foot-controller includes a plurality of pressure sensors mounted at selected locations on a substrate. The microprocessor converts sensor inputs from the foot-operated controller into commands for a controllable electromechanical device such as a prosthetic hand. Commands may be communicated via a radio transmitter or via hard-wiring.
1. A prosthetic system comprising:
a controllable prosthetic device;
a shoe insole insert including a substrate having a plurality of pressure sensors mounted at selected locations on the substrate to facilitate control of the controllable prosthetic device by application of pressure from selected parts of a foot to the sensors; and
a microprocessor for receiving input from the sensors and converting the sensor inputs into commands for the controllable prosthetic device.
2. The prosthetic system of claim 1 , wherein the prosthetic device is a prosthetic hand.
3. The prosthetic system of claim 1 , further comprising a radio transmitter for sending the commands to the controllable prosthetic device.
4. The prosthetic system of claim 1 , located on or within a shoe.
5. The prosthetic system of claim 1 , in which the microprocessor is hard-wired to the controllable device.
6. The prosthetic system of claim 1 , wherein the microprocessor is located on the substrate.
7. The foot-operated controller of claim 1 further comprising a controllable prosthetic device operatively connected to the microprocessor to provide commands to the controllable prosthetic device in response to input from the sensors of the foot-operated controller.
