Recycle Rush is the name of the 2015 FIRST Robotics Competition challenge. Two alliances of three robots each compete to pick up and stack totes on scoring platforms, put pool noodles ("litter") inside recycling containers, and put the containers on top of scoring stacks of totes. There is also a coopertition aspect of the game where both alliances of teams can pool their totes and stack them on a step dividing the field. Along with these robot actions, human players can attempt to throw the pool noodles across the field into the opposing alliance's work zone. More information can be found on Wikipedia.
