Abstract
The electric wheelchairs are designed to assist disabled people. However, for people with disabilities who have a higher degree of impairment, such as quadriplegics, who cannot move any of the body parts except the head, medical devices for them are usually very complex, rare and expensive. In this paper, we improved an electric wheelchair model that is controlled by the motion of the head by using a microcontroller system. The system includes microelectromechanical components: tilt angle sensors and mechanical mechanisms. A new head-motion recognition technique based on processing angular acceleration data. The process control of wheelchair motion has been achieved by using 6050 tilt angle sensor and Arduino family UNO R3 microcontroller. The signal of head movement direction is sent to the microcontroller. Depending on the orientation of the sensor, microcontroller will control wheels, such as turn left, turn right, moving forward or backward with the help of DC motors.
