Description of a toy-like device that allows children with mobility disabilities to practice with a joystick control used on a full-size power wheelchair. The Wireless Remote Control Wheelchair Trainer (WRCWT) was developed by an engineering student at the University of Massachusetts at Lowell following design requirements from the client, a children’s hospital. The structure of the WRCWT includes an 18 inch tall toy wheelchair mounted on a motorized toy car frame 6 inches high. The wheelchair and remote control have an on/off power switch. The remote control step design is similar to that of a controller on a real power wheelchair. The joystick can move in a 360 degree rotation. The transmitter and antenna are placed inside the remote control joystick. The design used a window comparator to connect the 3 circuits together. The transmitter sends an electromagnetic signal through the antenna. Two 1.5 volt batteries provide the power to turn on the transmitter and receiver. The transmitter module, consisting of an oscillator, modulator, and amplifier, sends a radio frequency wave through the antenna to the receiver. The receiver is mounted on the bottom of the toy wheelchair, where its antenna receives the signal and then decodes it to navigate the position desired by the user. Project cost was about 170 dollars.
