“Controlling a robot car wirelessly is very interesting for a beginner or new in the robotics field. But the main question is how to make a robot car?. In this tutorial, we will cover how to make an android controlled robot car. For this project, we have two sections. One is transmitter and second is a receiver. Here transmitter is an android phone and connected with the receiver robot using the bluetooth connection. Android phone already has inbuilt bluetooth. To connect to this android bluetooth, we are using one bluetooth module to the receiver side. We pair both the bluetooth module. After pairing the android phone and robot, we use android application to control the receiver robot. We are using the Bluetooth Controller app to control the android robot. When a forward button is pressed ‘A’ is sent via this android bluetooth to the receiver bluetooth module. Same with other buttons. At the receiver, we write the code to accept the character ‘A’ and move the robot forward. Each button assigned a value, which is known by the receiver. And receiver takes action according to the value received. “
