The Robobrawl competition consists of 30-pound and 3D printed 1-lb combat robots from different universities and private teams fighting one-on-one matches in a double elimination bracket with the goal of destroying the opponent bot. It is held annually as part the UIUC engineering open house around the beginning of April.
Robobrawl uses a double elimination bracket. All teams start in the Winners bracket and get demoted to the Losers bracket after their first defeat. The winners of the Winners and Losers brackets then compete for the trophy with the Winners bracket team having to lose twice before they are out. This ensures all teams need to be eliminated twice before they are out of the competition.
