Rover is a miniature self-driving robotic car. We designed and made the car's speed-control system (PID control) and line-following system (also PID control). We also equipped the car with object avoidance in three-lane traffic. Rover uses magnets on the wheels and a hall-effect sensor to track speed and adjust power to the motor accordingly. Rover also uses a camera to locate black lines on a white surface, and it adjusts a servo-motor controlling its front wheels so that it can follow the line. Rover is equipped with five infrared range finders to check for objects in front of it and to check blind spots on both sides.
