Mobile-App Operated Smart Robot Car Using Arduino

This paper presents the design and implementation of a smart robot car that can be remotely controlled using a mobile application via Bluetooth connectivity. The system utilizes an Arduino microcontroller as the core processing unit, interfaced with a motor driver module and Bluetooth module (HC- 05) to enable wireless communication with an Android- based smartphone. The mobile application provides an intuitive user interface to control the movement and direction of the robot car in real time. This project demonstrates a cost-effective and flexible solution for wireless robotic control, making it suitable for educational purposes, home automation, and beginner- level robotics projects. The integration of Arduino and Android technologies showcases the potential for creating smart, responsive systems with minimal hardware and open-source platforms.
