Official Game Rules

RECYCLE RUSH is a recycling-themed game designed for the 2015 FIRST Robotics Competition (FRC). It is played by two Alliances of three teams each. Alliances compete simultaneously to score points by stacking Totes on Scoring Platforms, capping those stacks with Recycling Containers, and properly disposing of Litter, represented by pool noodles, in designated locations. In keeping with the recycling theme of the game, all scoring elements used are reusable or recyclable by teams in their home locations or by FIRST at the end of the season.

The 27 ft. by 54 ft. playing Field is bisected by a small Step which may not be climbed on or crossed by Robots. Thus each Alliance competes on their respective 26 ft. by 27 ft. side of the Field.

Each RECYCLE RUSH Match begins with a 15-second Autonomous Period in which Robots operate independently of their drivers. During this period, Robots attempt to move themselves, their Yellow Totes, and their Recycling Containers into the area between the scoring platforms, called the Auto Zone. Additional points are awarded if the Yellow Totes are arranged in a single stack.

Auto Point Values:

  • Robot Set – Value: 4
  • Tote Set – Value: 6
  • Container Set – Value: 8
  • Stacked Tote Set – Value: 20

Our Robot

General Robot

Gaia, our robot, was beautifully designed with reliability in mind. Our passion for consistence drove us to design a passive fork system for picking up totes. Coupled with a powerful chain-driven lift, this system is able to pick up a stack of six totes with a recycling container. Photoeyes have advanced this capability, allowing for almost completely autonomous tote alignment. Gaia is also equipped with a mechanism for punching recycling containers out of the way for a three tote autonomous. CORE is proud of Gaia, one of the most robust and advanced robot we have ever created.
