3. 1.About 1.85%(131,800,000) require the assistance of wheelchair
2.Traditional motor wheelchairs are controlled using a joystick. But some
patients are unable to use joystick due to the lack of force or psychomotor
problem.
3.This is the main motivation that inspired us to develop a smart wheel chair
which can be controlled using smart phone mainly using gesture.

11. 1.MPU 6050 is used here to detect the motion of the hand
2.By the movement of hand it will move forward, backward, left
& right.
3.An Arduino nano is used as a controller
4.RF transmitter is used to send data to the main wheelchair
body
Hand Gesture Control

12. 1.The direction control of the wheelchair is set on the android software.
2.By touching the direction, it will send the signal to the wheelchair through Bluetooth module HC-05.
3.The Bluetooth module receives the signal and gives command the motor driver to move to its given command.

13. 1.A tilt sensor is set in the project. The sensor is also known as earthquake
sensor.
1.It has been used to observe the deflection of the wheelchair.
1.If the wheelchair falls in to an accident and fall in to the ground it will
light up and inform people about the accident.
Emergency System

14. 1.This feature will keep the wheelchair away from the obstacles and stops it immediately.
2.For this obstacle avoiding system, sonar sensor has been used.
3. sonar sensor has been used in this project. Sensors has been set in the front side, left side, right side, back side.
4.Whenever it gets any obstacles in its surrounding it will not execute its operation. It will stop from a limited
distance
