Hand Gesture Controlled Wheelchair

The aim of this paper is to prepare a Hand Gesture Controlled Wheelchair for the physically disabled people who face difficulty in moving from one place to another in day today life. These days joystick controlled wheel chair is available in the market whose cost range between Rs 80000 to Rs 150000. We have prepared this Hand Gesture Controlled Wheelchair in Rs 22000. An accelerometer is used as a sensor which gives an analog signal on its movement in any of the 6 axis directions that is positive X axis negative X axis positive Y axis negative Y axis positive Z axis negative Z axis. In this project we have considered X and Y axis for the direction. Further the input from sensor is given to encoder which sends the data wirelessly through the transmitter then the data is received at the receiver end and the sensor data is decoded and finally given to microcontroller. Based on data received the from accelerometer the microcontroller sends the signal accordingly to relays to move the wheelchair in forward backward left right directions. The accelerometer used here is MEMS micro-electromechanical system.
