PROJECT OVERVIEW 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.

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

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

PROJECT COMPONENTS 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).

DEVELOPMENT OF ANDROID APP

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.

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.

BENEFITS 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.

APPLICATIONS AND FUTURE SCOPE

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.
