Conclusion Then according to position of cornea we control the movement
of wheelchair in front, left & right side with 434 MHz Tx-Rx
We also provide obstacle protection by using ultrasonic sensor
Future scope
It will develop new era of super smart technology
With multi-interfacing it has many uses in future
