Tin Shredder was a middleweight robot built by The Gow School from South Wales, New York[1] which competed in the 2009 BattleBots High School Championship.

An invertible wedge-shaped robot with two pairs of rear-mounted wheels on the top and bottom (similar in alignment to famous UK Robot Wars heavyweight Pussycat), it was armed with a spinning drum embedded into the lower parts of the wedge.

One of two entries from the team alongside The Piecemaker, Tin Shredder achieved one of the most successful runs of the entire High School Championship, winning five consecutive matches in the main bracket to qualify for the overall final. However, it was defeated by shell spinner The Blender - an opponent it previously won against to reach that stage - resulting in Tin Shredder finishing the Championship as runner-up with a 5-1 record.[2][3]

Robot History[]

High School Championship 2009[]

The Blender vs Tin Shredder

Both robots collides, showering the floor with sparks.

Tin Shredder's first fully-documented fight was its Round 5 match-up against The Blender, deciding the first place in the overall final. Tin Shredder drove at The Blender, getting caught on the hellraisers. The Blender was deflecting Tin Shredder's rushdown attempts for a moment. The trend of the engagement was reversed later on as Tin Shredder got under The Blender a few times. The Blender took a bump from the hell raisers before hitting Tin Shredder away. The Blender was then wedged under by Tin Shredder and left under the pulverizer where it got hit once. The Blender escaped and ran away, getting caught by the hell raisers again. Tin Shredder took chase and got caught by the hell raisers as well, landing on The Blender, which started hitting the base of Tin Shredder. Tin Shredder escaped and The Blender was then pushed back by Tin Shredder. The two robots then got caught by the hell raisers, the two of them continuing to fight before they got caught by the hell raisers again. Tin Shredder then pushed The Blender into the screws before a bit of metal was made loose before Tin Shredder tried to wedge under The Blender. The Blender continued to hit Tin Shredder as it emitted smoke until the end of the fight. Tin Shredder won the unanimous judges decision, stating that it controlled the match.

The Blender vs Tin Shredder II

Tin Shredder gets its wedge piece knocked out.

For the title of champion, Tin Shredder fought The Blender again after it came through the losers bracket. In this fight, Tin Shredder changed strategy and did not drive at The Blender like it did in the first fight between the two robots. The Blender landed a few hits and missed a few. One of such hit damaged the corner of Tin Shredder's wedge. Tin Shredder reared up and bounced The Blender off its wedge twice, where it nearly took a hit from the pulverizer. The Blender was caught by the hellraisers before it continued hitting Tin Shredder, which was hobbling around. Tin Shredder had stopped moving and The Blender struck it once more, knocking the end of the wedge loose before ripping it off altogether. Tin Shredder was counted out, becoming runner up of the High School Championship with an impressive 5-1 record.
