Abstract: The Head motion controlled wheelchair is propelled by means of an electric motor rather than manually. Quadriplegics are one of the many physically disabled people that require such wheelchairs. They have paralysis of all four limbs and the torso that may be caused due to spinal cord injuries, strokes or cerebral palsy. They have no control over their hand movements and cannot grasp things or perform motions that might allow them independence over their movements. The tilting movements of the head in the four directions- forward, backward, right or left-would cause the wheelchair to move in the signaled directions. Quadriplegics rely on power wheelchairs for mobility, but the hands-free controller systems currently available are obtrusive and expensive. Smart wheelchair is an innovation that has an intention to create a difference for the activities of the people who are restricted by movement. This is an idea to ease those patients, who cannot perform hand movements in a way that can move a wheelchair. In this paper, we discuss about the working model of a head motion controlled wheelchair using Internet of things (IoT). The movement of the head is detected by MPU6050 and the signal is transmitted to the microcontroller. Then controller processes the signal and motion of wheelchair is enablesthe navigation. The wheelchair was capable of moving left, right, forward and backward direction and it is capable of doing tasks like navigation, obstacle detection, etc. using sensors and intelligence.
