FIRST STRONGHOLD (2016)
Today, and at more than 125 events around the world this season, Alliances of three robots are on a Quest to breach their opponents’ fortifications, weaken their tower with boulders, and capture their tower. STRONGHOLD is the medieval tower defense game for the 2016 FIRST Robotics Competition. The game involves robots overcoming defensive obstacles, shooting foam balls known as boulders, and attempting to capture their opponent's tower within a two minute and thirty second match.
The game is played by two alliances of up to three teams each, and involves breaching the opponents’ defenses, known as outer work as well as capturing their tower by first firing "boulders" (small foam balls) at it, and then surrounding or scaling the tower using a singular rung on the tower wall. Points are scored by crossing elements of the tower's outer works, shooting boulders into the opposing tower's five goals in order to lower the tower strength, and by surrounding and scaling the tower.
