Autonomous systems, especially in robotics, are transforming industries by performing complex tasks efficiently. Obstacle avoidance is crucial for autonomous robots, allowing them to detect obstacles in real-time and reroute themselves to avoid collisions. By integrating ultrasonic sensors and Arduino, this robot can autonomously navigate various environments. This project presents an Obstacle-Avoiding Robot designed with built-in intelligence that navigates autonomously using an algorithm. The robot detects and avoids obstacles, allowing it to move efficiently in unknown environments without human intervention. This flexibility makes obstacle-avoiding robots ideal for dynamic settings, enhancing their overall efficiency. The ultrasonic sensor is vital for this project. It transmits ultrasonic signal bursts at 40 kHz, which bounce back when an object is detected. The sensor generates high-frequency sound waves and analyzes the echo received to measure the distance to obstacles. By continuously calculating this distance, the ultrasonic sensor enables effective navigation for the Obstacle-Avoiding Robot, ensuring safe and efficient movement. DC motors and l293d motor driver is uses for robot movement with a battery power. After an obstacle detection, the car changes its direction by making an autonomous decision. It can measure the distance between itself and surrounding objects in real time.
