CANCELLED - Seattle Bot Battles 2020

Due to COVID-19 this event has been cancelled.  We are exploring having an additional event in July or August.  As of now the next WAR event is Robothon in October.


Seattle Bot Battles is free for bot builders and spectators.  Come watch at the Seattle Center Armory building Saturday May 9th and Sunday May 10th.  Robots from the 150g Fairyweight to the 30pound Sportsman class will compete to see which bots are the best in the North West.

Event Format and Rules

Western Allied Robotics events use a modified double-elimination format. The final is decided  with a single final match. If there are 5 or fewer bots in a weight class they will use a round-robin format. Please read the Rules to make sure your bot qualifies to compete. 

We've doing 30-sportsman robots again!  

Build something and help grow this weight class for WAR!  You can find the Sportsman rules here starting section 4.2.  There will be a few changes to the rules for this event. 

Suggested Donations

We have a suggested donation of $20 per bot to help cover our costs.  WAR events are Free for builders but we do have storage, arena maintenance and other event related expenses.  All of the money we collect goes to the Seattle Robotics Association which is a registered 501(c)(3) non-profit.  Please donate if you can but donating is not a requirement to compete. 


Sportsman, Hobby and Beetle robots will fight in a 12'x16' arena with a pit in one corner.  The pit has a steel edge around it that reduces the chance of accidentally driving in.

Antweights, Plastic Ants and Fairy robots will fight in a 5'x6' arena with a small pit in one corner.  The exact design of the pit is TBD but like the big arena it should be difficult to accidentally drive into it.

Pit Tables

Pit table space may be limited so plan accordingly. Also, the pit area will not be secure from Saturday night to Sunday morning. Robots and tools will need to be taken home or moved to a storage room at the venue. If you have any questions let us know via email or the Western Allied Robotics Facebook Group. If registration hits capacity we may have a 4-bot per team limit to make sure everyone gets a chance to compete.
