Description of the project:

Bluetooth controlled robot using Android mobile project makes use of an Android mobile phone for robotic control with the help of Bluetooth technology. This is a simple robotics project using a microcontroller. We have already seen Mobile Controlled Robot using DTMF technology which uses a call-based method to control the robot. Also, many wireless-controlled robots use RF modules. The control commands available are more than RF modules. The smartphone-controlled robot is superior to all these robots.

This project is a Bluetooth-controlled robot. For this, the android mobile user has to install an application on her/his mobile. Then the user needs to turn on the Bluetooth on the mobile. The wireless communication technique used to control the robot is Bluetooth technology. Users can use various commands like moving forward, reverse, stop move left, and move right. These commands are sent from the Android mobile to the Bluetooth receiver. The android-based robot has a Bluetooth receiver unit that receives the commands and gives them to the microcontroller circuit to control the motors. The microcontroller then transmits the signal to the motor driver ICs to operate the motors.

Dimensions of the Robot: 11 Centimeter by 21 centimeter

Description of the Bluetooth controlled robot using Android mobile in detail:

This project mainly consists of the following blocks:

1. Android mobile
2. Bluetooth receiver unit
3. Microcontroller
4. LCD Display
5. Motor Driver
6. DC motors

Android Application

Below is the screenshot of the Android application which is used in this project to control the Robot. This application has 9 keys/commands. We have used 7 commands. Commands 7 and 9 are not used and are reserved for future scope. Users can even rename these key texts as Forward / Reverse using the Set Keys option. The user needs to turn the Bluetooth on his/her mobile and press the scan button as shown below. Then connect to the Bluetooth receiver on the robot. Once the connection is established then the application will show the connected status as shown below.

Applications and Advantages of Bluetooth controlled robot using Android mobile:

1. The robot is small in size so can be used for spying.
2. With a few additions and modifications, this robot can be used in the borders for detecting and disposing of hidden land mines.
3. The robot can be used for reconnaissance or surveillance.

Future Development:

1. We can interface sensors to this robot so that it can monitor some parameters.
2. We can add a wireless camera to this robot.
