3. Introduction
Now-a-days transportation has become great
difficulty to the individual to reach the destination on
time, every one are having their own vehicle.
And the people with all body parts are fortunate but
when it comes to physically challenged people it’s
very unfortunate that the people with partially
disabled with hands can’t drive vehicle with the help
of steering.
In the Buses or Trains they are provided with
minimum reservation and which will be very
disappointing and they also don’t dare to buy a
vehicle and assist with a driver which will cost a lot .
So this project will be a great solution for them.

4. long life cycle
12V 1.3Ah sealed lead acid battery
10. General Features:
Sealed and maintenance free operation.
Non-Spillable construction design.
ABS containers and covers(UL94HB, UL94-
0)optional.
Safety valve installation for explosion proof.
High quality and high reliability.
Exceptional deep discharge recovery
performance.
Low self discharge characteristic.
11. Working
The person who is driving car will be equipped with a
device which is placed around the neck of the person
who is driving the car which is helpful to move the
steering forward and reverse direction without any
physical or mental stress .
The project uses 2 geared motors of 60RPM to drive
the prototype of car.
Also this car can take sharp turnings towards left and
right directions.
12. This project uses AT89S52 MCU as its controller.
We are also using four switches in the circuit which
will be ON when the person will move neck forward
and backward.
This project uses 12V Lead Acid battery which drives
two DC motors with the help of H-Bridge Circuit.
13. Advantages
The physically handicap Person(hands disable) can
drive the car as usual as normal person
No need to assist by driver it will save money
Low cost
Reliable
Even normal person can drive a car .
15. Conclusion
The project” Design and implementation of car
driving controller system for physically handicapped”
is designed, implemented and tested successfully ,
which is boon for PH Peoples. Who can expect the
same comfortable and luxurious life as normal people.
