Register here for our next KILLSWITCH Cardboard battle! This competition will take place during our 2025 Maker Market on Sunday, September 28 from 12 noon to 5pm (or until we’re done!).

Knox Makers members have two ways to enter: you can source your own parts and build your own robot in accordance with the rules linked below, or you can attend a Guided Robot Building Workshop to be held in the coming weeks. ** Note that if you attend one of the Guided Building Workshops your registration for that bot is already included, you do NOT need to register it here!

For non-members, please review the rules link below and reach out if you have questions.

If you are a non-member, please feel free to visit us on one of our KILLSWITCH Open Pit / Open Sparring Evenings! You’ll have the opportunity to meet and chat with our member builders as well as check out our arena in person. Bring your bot and you can test it out in our arena and there might also be the opportunity to engage in some informal sparring with some other participants.

Individuals and teams may enter as many robots in the competition as desired but each bot must be registered separately.
