This project demonstrates the design of an obstacle detection robot using Arduino and three SRF ultrasonic sensors positioned at the front, left, and right. The robot continuously monitors its surroundings to detect obstacles and make navigation decisions. This teaches students how to interface multiple sensors, implement basic autonomous navigation logic, and process real-time sensor data in a simulated environment. 1. Learn how to interface multiple SRF ultrasonic sensors with Arduino. 2. Understand the principles of obstacle detection and navigation logic. 3. Explore programming techniques for real-time sensor data processing and decision-making. 4. Gain practical experience in designing basic autonomous robotic systems.
