A robot that will autonomously push a block of wood out of a ring. It is intended for a mini sumo robot competition. The robot will initially spin in a circle and use its two ultrasonic sensors to locate the block of wood. Once both sensors see the block, the robot will move forward and use its color sensor to determine when it has reached the white edge of the ring. It will then back up to the center of the ring and continue looking for more blocks to push.
