This event requires navigation skills and speed.

Objective: The robot must navigate a maze from a starting point to the finishing square.

6. 4 way intersections are allowed.

7. The Finishing Square is 4” by 4” solid black square with it’s center on the 10” grid.  It will always be at the perimeter of the maze.

8. Starting points will always be at the perimeter.

9. Loops are allowed.

10. All lines will be straight.  All corners and intersections will be at 90 deg angles.

11. Maze must be designed and built by a non-competitor.

12. No programming between runs; however, mode switches are allowed.

13. Maximum Arena Dimensions is 144” x 72”

Starting: The contestant will place the robot at the designated starting point of the maze.  Sensor calibration is permitted using the a maze line or finishing square and it does not count against time.

Timing: The time will be the best of 2 or 3 attempts. Time stops when any part of the robot follows the line to and over the goal.
