Obstacle Avoiding Robot Car

Abstract: Robotics and autonomous systems play a crucial role in modern technology, with applications that span from personal assistance to industrial automation.To avoid collisions, any mobile robot must navigate its surroundings safely and identify obstacles in its path. Although traditional remote-controlled (RC) vehicles can be operated manually, their lack of environmental awareness renders them susceptible to accidents. This project introduces an obstacle detection robot car that utilizes an Arduino microcontroller. The system is equipped with an HC-SR04 ultrasonic sensor to detect nearby objects and avert collisions. Furthermore, an HC-05 Bluetooth module is incorporated to facilitate wireless manual control. The robot car operates in two modes: an autonomous mode that automatically detects and avoids obstacles, and a manual mode that allows control via Bluetooth and a smartphone application. The Arduino Uno processes sensor data and user commands to manage the robot's operations.
