This document describes the design of a smart wheelchair that can be controlled via smartphone. It contains sections on the components needed including an Arduino microcontroller, Bluetooth module, ultrasonic sensor, and DC motors. The wheelchair is designed to be comfortable, safe, and enable users to participate in daily activities. It has advantages like low cost, advanced technology, and stability. Future improvements could include control via head motion, gestures, eye tracking, or voice commands.

3. INTRODUCTION
o Wheel chair is the best assistive device used by
elder and disabled people.
o The driving and controlling of traditional wheel
chair are much harder task.
o Our aim is to build a low cost and powerful
wheel chair which helps the handicapped people
to travel without depending others.
o Introducing a prototype of cost effective
electronic based smart wheel chair.
o Easy to operate, because this wheel chair can
operated even by a user with his/her
smartphones.

4. WHEELCHAIR DESIGN
o Wheelchairs should be designed to enable
their users to participate in as many
activities as possible.
o As a minimum, a wheelchair should enable
the user to lead a more active life without
having a negative effect on their health or
safety.
o Comfort and safety are two important
factors affecting the quality of life of long-
term users

5. WHEELCHAIR DESIGN

6. COMPONENTS / MATERIAL NEEDED
o Hardware
o Aurdino uno microcontroller.
o Bluetooth module
o Ultrasonic sensor
o Dc motor
o Smartphone
o Wheel chair components
o Software
o Aurdino software ( for microcontroller )
o Aurdino Bluetooth ( for smartphone )

7. AURDINO UNO
o Arduino is an open-source electronics platform based
on easy-to-use hardware and software.
o Arduino boards are able to read inputs - light on a
sensor, a finger on a button, or a Twitter message -
and turn it into an output - activating a motor, turning
on an LED, publishing something online.
o You can tell your board what to do by sending a set of
instructions to the microcontroller on the board.
o To do so you use the Arduino programming
language (based on Wiring), and the Arduino
Software (IDE), based on Processing.

10. COMMANDS AND ITS OPERATION
• The different directions of motions possible are:
forward, backward, left, right and stop.
• In achieving the task the controller is loaded with
program using the arduino programming language
and arduino development environment.

11. ADVANTAGES OF SMART CONTROL
o Makes your move smarter.
o Low cost wheelchair with advanced
technology.
o Well designed ergonomics helps the chair
stable.
o Wheelchairs are highly beneficial to senior
citizens because it provides you with great
comfort, mobility, independence and
freedom.

12. TESTING MODEL

13. FUTURE SCOPE
o Using head motion.
o Using hand gestures.
o Using eyeball movement.
o Using voice command and etc.,

14. CONCLUSION
• It is going to bring a revolutionary in the
sense of cost cost management.
• Only fewer components are required and if
any damage it is easily replaceable.
• Helps physically disabled to reduce the
mechanical energy applied to move.
• Smartphones become an essential tool to
control all the electronic components.
