Every wheelchair is manually operated to move in and around. However, a smart wheelchair brings independence and effortlessness to a person. A Smart Wheel Chair is mechanically controlled devices designed to have self-mobility with the help of the user command using head/hand effortlessly. This reduces the user�s effort to drive the wheels of the wheelchair. Furthermore, this provides an opportunity for visually or physically impaired persons to move from one place to another. Even though a persons� the body is fully or partially paralyzed only his head/hand movement will help the wheelchair to move front, back, left, right. There is wireless communication between the human and the wheelchair. The equipment is kept on his head/ in his hand which detects the movement of the person. If the device finds the swing of the head front then the chair moves forward automatically. The procedure is similar to the other directions such as left, right, backward. If the head is still without any swing then it is considered as a stop. The operation of the experimental model of our device is based on pairing the Bluetooth of the mobile to the Bluetooth module placed in the wheelchair. The Arduino blue control app acts as an intermediate to find the movement of the human and the Arduino uno helps in assisting the Bluetooth and wheels movement according to the code. The L-298 in between the Arduino and wheels helps in converting the voltage that is required for wheels movement.
