Abstract: This paper presents a joystick controlled wheelchair with automatic speed control. This system enables the person on the wheelchair to control the motion of the wheel chair and controls speed of the motor automatically. Therefore, even if a person who knows only directions and has to travel on slopes can easily use this wheelchair as it has automatic speed control. Additionally, due to speed control on feels safe and secure sitting on it. The speed is controlled by pulse width modulation and the slope is measured using an accelerometer. Depending upon the pulse width set for a particular slope the speed of DC motors will change. This prototype mechanism can be mounted below the seat of the wheelchair and can be tested for different slopes and their speeds
