The document describes the design of a robot that can be controlled using an Android mobile app via Bluetooth. The robot uses a PIC16F877A microcontroller interfaced with a Bluetooth module to receive control commands from the app. The app allows sending commands like forward, backward, left, and right to move the robot in different directions. The purpose is to provide a simple and low-cost robot architecture that is also useful for educational robotics projects.

- 2. A robot is usually an electro-mechanical machine that is guided by computer and electronic programming. Many robots have been built for manufacturing purpose and can be found in factories around the world. Designing of the latest inverted ROBOT which can be controlling using an APP for android mobile. We are developing the remote buttons in the android app by which we can controlthe robot motion with them. And in which we use Bluetooth communication to interface controller and android.
- 3. Controller can be interfaced to the Bluetooth module though UART protocol. According to commands received from android the robot motion can be controlled. The consistent output of a robotic system along with quality and repeatability
- 4. Nowadays smart phones are becoming more powerful with reinforced processors, larger storage capacities, richer entertainment function and more communication methods. Bluetooth is mainly used for data exchange; add new features to smart phones. Bluetooth technology, created by telecom vendor Ericsson in 1994 shows its advantage by integrating with smart phones. It has changed how people use digital device at home or office, and has transferred traditional wired digital devices into wireless devices
- 6. A smart phone Android operated robot. Now here is a simple to control your robot car using Bluetooth module HC-06 and 89c2051 microcontroller with your android Smartphone device. The controlling devices of the whole system are a microcontroller. Bluetooth module, DC motors are interfaced to the microcontroller. The data receive by the Bluetooth module from android smart phone is fed as input to the controller. The controller acts accordingly on the DC motor of the robot. The robot in the project can be made to move in all the four directions using the android phone
- 7. . The direction of the robot is indicators using LED indicators of the Robot system. In achieving the task the controller loaded with program written using Embedded ‘C’ Languages. Android smart phone controller Bluetooth robot using microcontroller is shown in figure
- 8. The purpose of our research is to provide simpler robot’s hardware architecture but with powerful computational platforms so that robot’s designer can focus on their research and tests instead of Bluetooth connection infrastructure. This simple architecture is also useful for educational robotics, because students can build their own robots with low cost and use them as platform for experiments in several courses.

- 12. 1 First make sure your HC-06 Bluetooth module is paired with your mobile. The default password for pairing is “1234” or “0000”. Check the manual of Bluetooth module. 2 Click on “SELECT DEVICE” icon to select paired Bluetooth module. 3 When press “up arrow” it sends the data “A” to Bluetooth module connected with the circuit. When microcontroller detects “A” the robot/robot car moves FORWORD.
- 13. 4 When press “DOWN ARROW” it sends the data “B” to Bluetooth module connected with the circuit. When microcontroller detects “B” the robot/robot car moves REVERSE. 5 When press “LEFT ARROW” it sends the data “C” to Bluetooth module connected with the circuit. When microcontroller defects “C” the robot/robot car turns LEFT. 6 When press “RIGHT ARROW” it sends the data “D” to Bluetooth module connected with the circuit. When microcontroller defects “D” the robot/robot car turns RIGHT.
- 14. The knowledge is ever expanding and so are the problem which the mankind strive to solve. In this spirit, it is hoped that the current activity will lead to further enhancements. For example; work on future for military purpose by the robot.
