What is Recycle Rush?

Recycle Rush is the 2015 FIRST Robotics Competition, and involves stacking large tote boxes, cylindrical recycling bins, and pool noodles. With an initial 15 second autonomous period, where the robots run on pre-programmed instructions, matches continue 2 minutes and 15 seconds after with a tele-operated period when robots are controlled by human drivers.

The game is played on a carpeted field that is 27 ft. by 54 ft. Bisecting the field is a 6 inch tall step which may not be crossed by any robots, separating the red and blue alliances from physical interaction. On each side of the field, are three sections: the landfill zone, auto zone, and three staging zones.

Recycle Rush Field Design

The objective of the game is to stack grey tote boxes, recycling bins, and pool noodles on scoring ramps located on either side of the field. More points are awarded the higher the stack. Totes are initially located on the field in the landfill zone (oriented forward, sideways, and upside down) and on the step bisecting the field. Additionally, they are located off-field where human players may feed them into the field through slots along the field boundary. Cylindrical recycling bins also begin on the field atop the bisecting shelf.

Throughout each match, human players may throw ‘litter’, or pool noodles, onto the opposing alliance’s side of the field. In the last 20 seconds of the match, human players cannot throw noodles. Noodles placed inside recycle bins are worth 6 points, and litter gathered into the landfill zone will be worth 1 point. At the end of the match, any noodles remaining in the auto zone will be considered ‘unprocessed litter’ and will add 4 points to the opposing alliance’s score.

The system for scoring this year is extremely complicated. Here is what all of the possible ‘stack’ combinations look like.
