Multi Technology Based Controller for Wheelchair Locomotion

An automated system is developed to control the rotation of the wheel chair based on touch screen and head movement by the physically challenged person. Independent movement can be done by them with the help of an accelerometer device which is fitted on person’s head and a touch screen is placed with the wheelchair which can be operated by the person [1]. Based on the touch and head movements, the accelerometer and the relay will drive the motor fitted with the wheel chair. The wheel chair are often driven in any of the four directions. The machine-controlled wheelchair is based on simple electronic control system and the mechanical arrangement that is controlled by a Programmable Interface Controller. This automatic wheel chair additionally helps people who have various other disabilities by simply using the accelerometer and touch screen to manage the wheel chair movement. Other than this we have implemented the subsequent applications in our wheelchair: GSM communication, Heart Rate Monitor, UV Sensor.
