Implementation of Head and Finger Movement Based Automatic Wheel Chair

An automated system is to be developed to control the motor rotation of wheel chair based on head and finger movement of physically challenged person. In order to facilitate these people for their independent movement, an accelerometer device is fitted on persons head and a flex sensor is fixed in a glove which is to be wear by the person. Based on the head and finger movements the accelerometer and the flex sensor will drive the motor fitted to the wheel chair. The wheel chair can be driven in any of the four directions. The automated wheelchair is based on simple electronic control system and the mechanical arrangement that is controlled by a Programmable Interface Controller. This automatic wheel chair also helps people who have various other disabilities to sit on the chair and just hold the accelerometer and move it over to control the vehicle movements. In this paper the wheel chair has been mimicked using a robot.
