Abstract :

The aim of this paper is to prepare a Hand Gesture Controlled Wheelchair for physically disabled people who face difficulty in moving from one place to another in day-to-day life. These days joystick-controlled wheelchair is available in the market whose cost ranges between Rs 80,000 to Rs 150,000. For that, we have prepared this Hand Gesture Controlled Wheelchair at a minimal cost so that anyone can easily buy it. An MPU6050 is a 6 DOF (Degrees of Freedom) or a six-axis IMU sensor, which means that it gives six values as output. It consists of a three-axis accelerometer and a three-axis gyroscope. Which gives an analog signal on its movement in any of the 3 axis directions, that is X-axis, Y-axis, Z-axis. In this project, we have considered the X and Y axis for the direction. Further, the input from the sensor is given to the 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 motor driver L298. Based on data received from the nRF24 module sends the signal accordingly to relays to move the wheelchair in forwarding, backward, left, right directions.
