A joystick controlled wheelchair.
A joystick based motor control for a child's wheelchair was designed and built. The design is intended to allow a child with limited strength to control a wheelchair. There is a master power switch that can be turned on and off by an instructor in a classroom situation. The joystick is made from resistors that provide the input to the pulse width modulation (PWM) circuits. The motors for each back wheel are operated by an H bridge network. The controller is built but modifications are needed for it to work properly.
