Central Illinois Bot Brawl 2012 Line Maze Rules
The robot must be completely autonomous once the operator starts it. The robot must be no larger than 20 cm by 20 cm. It can be of any height. The maximum weight allowed is 3 kg (approximately 6.6 lbs). The robot can have a maximum of 7 buttons.
The course will be on a 4-foot by 8-foot table with a 2 by 4 fence. The playing surface is 45 inches by 93 inches. The course will be:
- Printed on a white material that is similar to wallpaper with a plotter printer.
- The lines will be ¾ inch and colored black.
- The course will be based on a grid of 7 1/2 inches. The lines will be no closer than 6 3/4 inches to each other. The lines will be no closer than 7 1/8 inches to the walls measured from the edge of the line to the edge of the wall.
- The accuracy of the lines and walls are within a quarter inch.
- The mat will be attached to the table by carpet tape around the edges as needed.
- All turns are corners and will be 90 degrees.
- There will be loops in the course.
- The start and stop will be separate.
- The start line will be a thin pencil line used to position the robot.
- The stop is marked by a 3 by 3 inch black square.
- Dead ends will end in the middle of a grid.
- Crossroads will be both tees, pluses, and ells
- The competitors will start in a random order.
- Each competitor will get 6 minutes with no breaks to complete the course a maximum of 3 times.
- The recorded time will be re-started for each of the attempts during a run. The recorded time will be started when the robot crosses the start line.
- If the contestant does not complete the course, the greatest distance covered on the prime path will be recorded.
- To restart the robot, the contestant can grab it or ask the judge to grab it.
- There cannot be any cues or inputs from any human being directly or indirectly while the robot is running the course.
- The operator is allowed to make minor changes to the robot’s mechanical hardware between attempts.
- The operator is allowed to make minor changes to the robot’s software between attempts by pushing buttons on the robot only. No other method is allowed.
- The fastest time or greatest distance covered on the prime path will count towards placement.
- The robot must follow the course from start to finish. If the robot goes off course and relocates the course at an advanced position, it must be restarted at the beginning. The robot will be considered off course if it completely leaves the line it was following and does not find its way back near the point that it left the line.
- A 10% bonus reduction of the completed time will be given if the robot stops on the square and signifies in some manner that it is done with the course. Stopping on the square signifies completion and will earn the robot the bonus, but competitors are encouraged to add an audible signal, visible signal and/or physical motion for entertainment purposes.
- The greatest distance covered along the prime path or the fastest time for completing the course after the bonus is applied determines each robot’s place in the competition.
- The robot must not damage the course.
Final note on the rules:
The intent of this event is for the robot to follow the line while navigating the maze from Start to Finish. If the judge interprets a competitor’s actions as attempting to circumvent this intent, then the judge has the right to disqualify that robot from this event and possibly the competitor from the entire competition. Someone entering the layout of the course into the robot in some fashion will be interpreted as trying to circumvent the intent of this event. This decision will be made in partnership with other members of the club.
