Thursday, April 14th through Saturday, April 16th
Oxford High School’s FIRST Robotics Team 2137 – TORC competed at the State Championship in Grand Rapids, MI at the DeltaPlex Arena. In preparation for this event, TORC spent the three weeks between their final district event and the State Championship troubleshooting the shooting mechanism to determine the reason for jamming issues they faced in the finals at the Marysville District event.TORC faced various issues with the robot while in Grand Rapids. A bad battery, loosening of an encoder wire, and a hex shaft coming out are just a few of the examples of issues that caused TORC’s losses on Thursday and Friday. Saturday TORC began to rally back and ended qualifications adding two wins. With 4 wins and 8 losses, TORC was ranked 77th out of 102 teams from around Michigan. Competing in the elimination rounds would now hinge on another team selecting TORC to join their alliance.

ranked 5th out of 411 teams in Michigan!
TORC competed at the district event at Waterford Mott High School. The 2016 FIRST
game is called STRONGHOLD and requires teams to shoot balls into low and high goals to capture the tower, cross any of nine defenses midfield, scale the tower, and get all three alliance partners parked on the batter before the match ends to score points. Ranking points are also earned by crossing at least four defenses two times each.
After competing in qualification matches all day Friday and Saturday morning, TORC was the number two ranked team out of 39 teams from around Michigan. This was impressive as TORC faced connectivity issues with the competition field on Thursday evening and encountered repeated stalling issues on the shooter mechanism on Friday.

The number one alliance of Team 67, HOT of Highland, Team 33, Killer Bees of Auburn Hills, and Team 4003, TriSonics of Allendale became the Waterford District Champions.
TORC did not come home empty handed. TORC was awarded the Excellence in Engineering Award, sponsored by Delphi which celebrates an advantageous machine feature. It was noted that TORC had used its CAD skills and engineering process to evaluate nine drive train options.Through research, prototyping, and evaluating testing data, TORC carefully selects the mechanisms it will then fabricate parts for, assemble, wire and program.
In addition, the teams have the opportunity to vote for one team to receive the Pit Safety Award. This is special because the competitors select the winner. TORC was awarded the Pit Safety Award. They also were runners-up for the Industrial Safety Award, sponsored by Underwriters Laboratories which celebrates the team that progresses beyond safety fundamentals by using innovative ways to eliminate or protect against hazards
