Implementation of Bluetooth Based Cargobot Using Controlled Arduino Robocar

This project presents the implementation of a Bluetooth-based CargoBot using an Arduino-controlled robotic car, designed for wireless navigation and basic obstacle detection. The robot can be remotely controlled via a smartphone Bluetooth application to move in four directions: forward, backward, left, right, and also includes a stop function. A Bluetooth module (HC-05 or similar) is interfaced with the Arduino to establish wireless communication between the robot and the mobile app. To enhance autonomous safety features, an ultrasonic sensor is integrated into the system to detect obstacles in the robot’s path. When an obstacle is detected within a predefined distance, the sensor triggers the Arduino to stop the robot and send a warning signal serially to the mobile application. This setup provides a low-cost, efficient, and scalable solution for smart cargo handling and remote navigation applications.
