This document describes the design of a Bluetooth controlled robot. The robot uses an Arduino UNO microcontroller to receive Bluetooth commands from an Android device app and control DC motors and a gripper. Key components include the Android device for control, Bluetooth module for wireless communication, motor driver to operate the DC motors for movement in four directions, and a physical robot body with wheels and gripper. Applications mentioned include use in industrial automation, commercial settings, assistance for mobility-impaired individuals, the toy and education industries. Educational robots in particular help children learn coding and programming skills through building and programming their own robots.

3. INTRODUCTION
AIM : To design a robot
which can be controlled by
using bluetooth.
Bluetooth controlled car is a
robot which is built using
Atmega8 microcontroller in
which serial communication
done via bluetooth and
programming is done in
embedded C language.

5. APPROACH
● Develop a robot which can receive
commands via bluetooth, properly.
● Implement an app which allows the
user to send commands via
Bluetooth.
● Commands received by Bluetooth
modem should be connected to
microcontroller.
● Microcontroller controls motors
which allows the movement of robot
in all the four directions and gripper
to handling physical objects.

6. COMPONENTS OF
ROBOT
1. Android Device
2. Controller: Arduino UNO
3. Bluetooth Module
4. Motor driver
5. DC Motors
6. Robot Physical Parts

7. ANDROID DEVICE
● Here, we are using an android OS
based smartphone for controlling the
Arduino Robot.
● Android OS conditions : to have
Bluetooth connectivity and an
Android User Interface app for
interfacing with the Arduino Robot.
● The Android User Interface app can
be designed according to user’s
needs.

8. BLUETOOTH
MODULE
● A bluetooth module is used for
interfacing the Arduino Robot with the
Android smartphone wirelessly.
● Enhanced Data Rate for both 3Mbps
and 2Mbps modulation modes.
● Low power operation.

9. MOTOR DRIVER
● For controlling the electrical motors used in the Arduino Robot, a motor
driver IC - L293D Push-Pull Four Channel Driver IC- is used.
● A single L293D IC allows two DC motors to drive on either one direction
simultaneously.
● The L293D designed to provide bidirectional drive currents.

10. DC MOTORS
The DC motors are used for the movement of the
Arduino Robot according to the input given by the user.

11. ROBOT PHYSICAL
PARTS
● Wheels
● Gripper
● Motors
● LED
● Battery

12. APPLICATION
● For industrial and commercial purpose.
● Can be used in remote area applications.
● Helpful for mobility impaired persons.
● Used in toy industry.
● For Pick and Place applications.
● Used in entertainment world.
● Robots are also used in education purpose.

13. ROBOTS IN TOY INDUSTRY
● Nowadays, robots are also used in toy
industries. Toy robots have captured the
imagination of kids as well as children
too.
● You don’t need separate control unit for
controlling the bot. As long as you have
either an IOS or android device, you
should be able to control it.

14. ROBOTS USED IN EDUCATION FIELD
● Educational robots have up-to-date computing
power and innovative engineering.
● These type of robots can be controlled via
apps, voice and gestures.
● Robots in education field helps children to
learn how to code.
● The activity of programming a robot and even
building one from a kit is an ideal way to teach
technology and engineering skills.

15. INDUSTRIAL AND COMMERCIAL USE
● Robots are basically made for
industrial and commercial purpose.
● In industry, robots has single
instruction to execute a single
command for a specificwork.
