Game Discription

The Re­bound Rum­ble ro­bot­ics game is played be­tween two Al­liances of three teams each. The Al­liances com­pete in a game very sim­i­lar to bas­ket­ball, ex­cept there are four bas­kets in­stead of one. Also, in the mid­dle of the field, the teams have to go over ei­ther a four inch tall bump or over what is more or less a teeter-tot­ter. They have to gain as many points as pos­si­ble in a two minute match.

Official Game Rules

The Re­bound Rum­ble ro­bot­ics game is played be­tween two Al­liances of three teams each. Each Al­liance com­petes by try­ing to score as many of the bas­ket­balls in the hoops as pos­si­ble dur­ing the 2-minute and 15-sec­ond match. Balls scored in higher hoops score Al­liances more points. Al­liances are awarded bonus points if they are bal­anced on bridges at the end of the match. In matches where op­po­nent Al­liances work to­gether to bal­ance on the white bridge, all par­tic­i­pat­ing teams earn ad­di­tional valu­able seed­ing points.

Our Success

2012 Wisconsin Regional

On March 22nd to 24th, 2012, our team went to the Wis­con­sin Re­gional. We were the re­cip­i­ents of mul­ti­ple awards, the most pres­ti­gious be­ing one of our me­chan­i­cal sub­team lead­ers, An­nalyssa, be­com­ing a Dean’s List fi­nal­ist. This award is pre­sented to two stu­dents who ex­em­plify the ideals of FIRST, and there was no bet­ter per­son to rep­re­sent our team and FIRST then An­nalyssa. In ad­di­tion to that, we also placed in the top 3 for Safety and 10 other awards. We also won the Gra­cious Pro­fes­sion­al­ism award, which is awarded to the team who rep­re­sents FIRST in the most pos­i­tive light. In the ac­tual com­pe­ti­tion it­self, we were ranked 14th. We made it to the semi­fi­nals with our al­liance that con­sisted of team 868 TechHOUNDS and team 2039 Rockford Robotics. In the semi­fi­nals, we lost in a ter­rific bat­tle against team 48 Delphi E.L.I.T.E., team 2826 Wave Robotics, and team 269 CooneyTech. This al­liance even­tu­ally went on to win the re­gional. The re­gional was not only fun, but a great learn­ing ex­pe­ri­ence for all of us, and we will use the knowl­edge we’ve gained to do even bet­ter at in­ter­na­tion­als!

2012 Lake Superior Regional

From March 8th through 10th, C.O.R.E. was in the Du­luth En­ter­tain­ment Con­ven­tion Cen­ter for the Lake Su­pe­rior Re­gional. Ranked 37th out of 64 at the very end, we made it all the way to the semi-fi­nals with Teens ‘Nto Technology 3840 and Inconceivable 2530, but were knocked out af­ter a close match which was won by the 1st seeded al­liance, con­sist­ing of MORE 1714, King TeC 2169, and Nordic Storm 3018. It was an honor to be able to go up against such a great al­liance. Con­sid­er­ing that our pro­gram­ming failed and we had to re-write it all on Thurs­day night be­fore the qual­i­fi­ca­tion matches started on Fri­day morn­ing, we did quite well. We won the In­dus­trial Safety Award spon­sored by Un­der­writ­ers Lab­o­ra­to­ries in Du­luth, our eighth time re­ceiv­ing the award.

2012 FIRST Championship

From April 27th to the 30th, C.O.R.E. was in the FIRST Cham­pi­onship! We did not make it out of our pools in New­ton di­vi­sion, as we placed 25th. How­ever, some­thing much big­ger hap­pened. We won the Un­der­writ­ers Lab­o­ra­to­ries In­ter­na­tional Safety Award! This means that we have the best safety pro­gram out of 400 teams! It was a fan­tas­tic ex­pe­ri­ence for the en­tire team. One of the high­lights of the event was when our ro­bot scored 4 balls in au­tonomous! Over­all, this was a fan­tas­tic ex­pe­ri­ence for the team.
