Lunacy is a game played on a field known as the CRATER (illustrated in the figure below). Two ALLIANCES, one red and one blue, composed of three FIRST Robotics Competition (FRC) teams each, compete in each MATCH. The object of the game is to attain a higher score than your opponent by placing the GAME PIECES in the TRAILERS hitched to the opposing ALLIANCE’S ROBOTS.
The playing field for Lunacy is a 27-foot by 54-foot carpeted area, bounded by two Alliance StationWalls and a Guardrail System. This field is known as the “CRATER.” The majority of the CRATERis covered by a 24-foot by 50-foot surface known as the “REGOLITH.” The REGOLITH is made of“Glasliner FRPtm” gel-coated, fiberglass-reinforced, polymer material. This forms a tough, rigidsurface that has been specifically selected to have a low coefficient of friction with the acetaltreadedROVER WHEELS used by the ROBOTS.
The Alliance Station Wall is 6-1/2 feet high, 27 feet wide, and centered on the ends of the CRATER.The center portion of the wall is composed of a three-foot high base of diamond plate aluminumtopped with a 3-1/2-foot high transparent acrylic panel. The bottom eight inches of this section is protected by a strip of bumpers, similar to the STANDARD BUMPERS on the ROBOTS. The bumpers are colored red or blue, to correspond to the BASE where they are located.
The Guardrail System is a horizontal pipe 20 inches above the floor, supported by vertical strutsmounted on a three-inch aluminum angle. A shield is attached on the inside of the Guardrail system, extending from the floor to the top of the guardrail, and running the length of the guardrail. The shield is intended to help prevent ROBOTS, in whole or in part, from inadvertently exiting the CRATER during a match. The Guardrail System defines the borders of the CRATER, except where it is bounded by the Alliance Station Wall.
Four gates in the Guardrail System allow easy access to the CRATER for placement and removalof ROBOTS. The gates are four feet wide and are located in each quadrant of the CRATER. The gates are closed and shielded during game play.
