2WD Obstacle Avoidance Robot Car
The 2WD Obstacle Avoidance Robot Car is a compact, Arduino-based robotic vehicle designed to detect and avoid obstacles using a fixed-position ultrasonic sensor. It is ideal for beginners, students, and hobbyists who want to explore the basics of robotics, electronics, and programming.
This version of the robot features a static (non-rotating) ultrasonic sensor that faces forward, allowing the robot to detect objects directly ahead and make smart decisions to avoid collisions. It's a great entry-level kit for understanding autonomous movement, sensor integration, and basic embedded systems.
