The 2017 FIRST Robotics Competition game, Steamworks, was played by two alliances of three teams each who competed on a field by scoring wiffleballs. The wiffleballs represent fuel which needs to be taken to a simulated boiler which transfers the generated steam into an airship in the middle of the field. Each alliance has one airship, which they pressurize with steam from the boiler and load with plastic gears from the field. At the end of the match, robots attempt to hang on team-supplied ropes attached to the airship for additional points.
