Pool-boy
Builder: David LeBlancMy Vex Pool Racer entry. The Ultrasonic sensor follows the wall of the 5' swimming pool, keeping it not too close but not too far. I banged this together in an evening, the coding took another Saturday to tweak to the point that it worked reliably. The angle of the sensor is somewhat critical for reliable operation.
