The video shows the robot making its way through the maze, hitting one wall and stopping just before the last turn. The second run in the video shows our robot reversing backwards into the finish line through the wall, scoring a time of 2.5 seconds with one wall hit.

The circuit uses an L293D motor driver to control the two motors with the Arduino MEGA. The Arduino uses three ultrasonic sensors to determine the location of the walls and change the speed of the motors.
