Steamworks is the name of the 2017 FIRST Robotics Competition challenge. Two alliances of three robots each compete to shoot wiffle balls which represent fuel into 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 can climb and hang on ropes attached to the airship for additional points. More information can be found on Wikipedia.
