Abstract:

People with disabilities due to serious spinal cord injuries cannot move the conventional type hand powered wheelchair without external assistance. Here we are developing a head movement based control system for wheelchairs. Here the head posture is tracked by an accelerometer, which directs the motor driver, using a microcontroller system. We provide ultrasonic sensors to avoid accidents. A GSM health monitoring system is also attached along this.
