Game Discription

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.

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.
