3. PROJECT OVERVIEW
3
 Purpose:
 Robot which can be controlled remotely by an Android
smartphone.
 Method:
 Build a robot which can receive
commands via bluetooth and work
accordingly.
 Develop an Android app which allows the user to sends
commands via Bluetooth.
 Commands received by Bluetooth modem
connected to microcontroller.
 Microcontroller controls motors which
allows the movement of robot in all the
four directions and gripper to handling
physical objects.

4.  The project is designed to develop a fire
fighting robot using android application device
for remote operation.
 The robotic vehicle is loaded with water tanker
and a pump which is controlled over wireless
communication to throw water
 At the transmitting end using android
application device, commands are sent to the
receiver to control the movement
Project overview

5.  When the robot faces a fire then it extinguishes
fire with the help of pump motor connected to a
water tank mounted on its body.
 Remote operation is achieved by any smart-
phone/Tablet etc., with Android OS, upon a GUI
(Graphical User Interface) based touch screen
operation.
 The android application device transmitter acts
as a remote control that has the advantage of
adequate range

6. PROJECT COMPONENTS
6
 Different components used are as follows:
 1. ATMEGA8L-8PU MICROCONTROLLER
 The AVR is a modified Harvard architecture 8-bit RISC single chip microcontroller
developed by Atmel. It uses on chip flash memory for program storage.
 It is a High-performance, Low-power AVR 8-bit Microcontroller with 130 Powerful Instructions -
Most Single Clock Cycle Execution.
 2. HC-05 BLUETOOTH MODULE
 The HC-05 small size Bluetooth TTL transceiver module are
designed for serial communication (SPP - serial port profile).
It allows your target device to both send or receive TTL data
via Bluetooth technology without connecting a serial cable to your computer.
 It has Coverage up to 30 ft / 10 m with Built in antenna.
 It has Power input: +3.3VDC (bluetooth module).

7. OTHER COMPONENTS

 WHEELS
 GRIPPER
 TOY MOTOR
 MICRO-SWITCH
 LED
 RESISTANCE

8. DEVELOPMENT OF ANDROID
APP8
 Android is an Open Source operating system based on
the Linux Kernel , and designed primarily for touchscreen
mobile devices such as smartphones and tablets.
 It was built to be truly open. For example, an application
can call upon any of the phone’s core functionality such
as making calls, sending text messages, or using the
Bluetooth, camera etc.
 The Android SDK provides the API libraries and developer
tools necessary to build, test, and debug apps for Android.

9. OVERVIEW OF “AC Robot”

 Using the Bluetooth APIs, an Android application can perform the following:
1.Scan for other Bluetooth devices
2.Query the local Bluetooth adapter for paired Bluetooth devices
3. Establish RFCOMM channels
4.Connect to other devices through service discovery
5. Transfer data to and from other devices.

10. BENEFITS
10
 Skills
 Selecting parts based on datasheets
 Practical aspects: sourcing parts, mechanical
fabrication
 Bringing a design from concept to implementation
 Android app development (Java, XML)
 Conclusion
 It is feasible to implement Bluetooth communication
between smartphone and microcontroller.
 The development of apps for Android in Android SDK
is easy and free of cost.

11. APPLICATIONS AND FUTURE
SCOPE11
 1. It can be used in various industries for picking various objects
where human intervention is not desired.
 2. On a large scale, it can be used to develop robots with military
applications. It can be used to target enemy without any human
being crossing the territory.
 3. It provides for more development of applications based on
android operating system. Such as , Application based on sensors
(accelerometer , gyroscope) etc.
This opens door for wide range of possible similar applications
 Remote starter for car
 Automation of household tasks
 4. It is robust, sensitive and fast moving, hence can be applied in
rescue operations.
 5. With tremendous smart phone in markets, it is bound to have
many more applications in near future.
