Wireless infrared data communication for a SMART/sup Wheel/

In order to send command signals to and collect data from a wheelchair during propulsion, an infrared data communication system was designed. The digital data from the SMART/sup Wheel/ goes to the transmitter attached to the wheel and is transmitted at a data rate of 38.4 kbps. The receiver gets the data at a distance of 6 meters and then the data is transmitted to the RS-232 serial port of a PC. The infrared chip set acts as a transceiver, so the command signal can also be sent to the SMART/sup Wheel/.
