Android application based robotic car using blutooth module

Robotics and wireless communication technologies have transformed the field of automation and smart control systems. With the rapid growth of smartphone technology, the integration of mobile applications with robotic systems has become highly efficient and user-friendly. This paper presents the design, development, and implementation of an Android Application Based Robotic Car controlled using Bluetooth wireless communication technology. The proposed system allows users to control a robotic vehicle through an Android mobile application that communicates with a microcontroller. The Android application sends movement commands such as forward, backward, left, right, and stop through a Bluetooth module connected to the robotic car. The microcontroller processes these commands and controls the motor driver circuit to drive DC motors accordingly. The system is designed to be low-cost, easy to implement, and reliable. It demonstrates how mobile-based control systems can replace traditional wired or remote control methods. This project also enhances knowledge of embedded systems, mobile application development, and wireless communication technologies. The developed system can be used in educational applications, surveillance systems, and automation projects..
