Crimson Bot Brawl - Fall 2025

Crimson Bot Brawl, hosted by Crimson Robotics at Washington State University, is WSU's bi-annual combat robotics competition. Over the past semester, Crimson Robotics members have been hard at work learning to design, build, and test their own Beetleweight combat robots, and Crimson Bot Brawl is an opportunity to put the results of their hard work to the ultimate test against bots built by members of the combat robotics community.

Crimson Bot Brawl will be held on November 15th, at the SPARK Building on the WSU campus. Doors will open for competitors at 8am, and for the general public at 10am.

Arena/Rules

• We will be using an 8'x8' arena for all matches, and adhering to the standard SPARC ruleset, found here.
• The tournament across all weight classes will follow a double elimination style. Each weight class will contain two brackets. The winner of each match will advance in the same bracket while the loser moves to the other. Losing two matches will eliminate the robot from the competition. Finals will consist of the winners of each bracket within the respective weight class.
