2017 challenge - "Steamworks℠"
tHE GAME pIECES
Stronghold℠ is played using special FIRST gears and balls. The boulders are 10 inches in diameter and are made of foam. Each boulder has the FIRST® logo printed on it. Each match begins with eighteen boulders in the arena; 6 in the Midline, 3 in each Castle, and 3 per alliance. Robots may start with one boulder each.
SCORING With Gears
Throughout the game, robots must weaken the defenses of the enemy alliance by driving over them. The Low Bar remains on the field during all matches, defenses in the middle position on the field change according to audience selection, and the remaining defenses are chosen by competing teams. During the autonomous period, robots can earn 2 points for reaching the outerworks and 10 points for crossing defenses. During the teleop period, crossing a defense earns 5 points. If a defense is crossed twice, it is considered damaged. By the end of the match, if any 4 of the 5 enemy defenses are damaged, the alliance receives points.
Steamworks℠ is played by two competing alliances on a flat, 27 x 54 foot field. Each alliance consists of three robots, which commands one airship, where two human players, called 'pilots' reside. Teams begin behind the baseline with a maximum of 10 fuel and 1 gear pre-loaded in each robot. A total of 500 fuel is available for robots to release during the match in hoppers that boarder the field. During a two minute and thirty second match, teams must score fuel and deliver gears to build pressure and engage rotors to prepare for liftoff. At the end of the match, each alliance can "board" their airship by climbing ropes deployed by the pilot.
The robots on each alliance attempt to score as many boulders into the opposing tower.
During the last 20 seconds of the teleop period, robots can extended to reach a rung, scale the tower, and earn 15 points.
The match begins with a fifteen second Autonomous Period in which robots operate independently of driver inputs. The robots use pre-programmed instructions to try to score as many points as possible. More points are earned during this period, rather than during the Teleoperated period.
Once the 15 seconds are up a Teleoperated Period starts. At this time, drivers take control of the robots and attempt to maximize their alliance score by delivering gears and scoring fuel. The Teleoperated Period lasts 2 minutes and 15 seconds, and ends with robots surrounding the airship and climbing their ropes. Once the time is up, all robots are disconnected from the controllers and the score is calculated. The winning alliance is the team with the most points at the end of the game.
