The number of Physically Challenged people, who wants to move around with the help of some
artificial means, whether through illness or an accident, is continuously increasing. Driving a wheelchair in
domestic environments is a difficult task for a normal person and becomes even more difficult for people with
arms or hands impairments. In this project we used Accelerometer, ultrasonic and infrared sensor systems has
been integrated in this wheelchair. We have a Pre fabricated Wheel Chair which can be driven with using
Accelerometer and with the possibility of avoiding obstacles using IR sensor and downstairs or hole detection
using Ultrasonic Sensor. Intended users control the system by wearing a glove fitted with accelerometer for
controlling the movement and direction of the wheelchair. The MEMS sensor senses the angle of the hand, i.e.
according to the tilt of hand it gives voltages to microcontroller. The main advantage of this wheelchair is low
cost, low power consumption, easy to control
