ABSTRACT: The objective of this study is to provide the physically disabled patients who had suffered from losing their extremities due to the accident, age or disease, with an easily controllable wheelchair. Those patients cannot use the manual wheelchair or electric wheelchair with joysticks due to their handicap. The movements of this wheelchair are controlled by head motions with the use of gyroscope sensor. The microcontroller is also used and it is programmed to make the wheelchair moves according to the corresponding motion from the patient’s head. Forward movement of the wheelchair due to tilting head forward, left tilt of the user's head will cause the wheelchair to move to the left and so on. An obstacle detection system is done by using ultrasonic sensors. This system showed very good results it will make the usage of this wheelchair safer as compared to standard ones. It will help in enhancing the quality of life for such people and make them less dependent on others. This wheelchair is low cost, provide ease of use and comfortable for the physically disabled patients.
