Emergencies In case of emergency, such as battery exposure, battery fire, or unsafe condition, such as an arena breech, or a loading door being opened during a match...

  1. The arena steward/judges will call a hold on the match, using the phrase "CEASE COMBAT". Immediately place your transmitter in the designated area and do not touch it until instructed to. Failure to comply can result in a forfeit of the match.

General Procedures

  1. Testing a weapon outside of the test box/arena will be grounds for disqualification from the event or explusion from the event.
  2. If a battery becomes exposed, the match is over. The arena steward/judges have final say over this safety issue.
  3. In the pits, keep you bots turned off, weapons safeties on and the wheels off the ground.
  4. We will have someone call next match, and on deck match. We will also try to post the current brackets and next fight within the Discord event channel. We have 20 minutes between matches for any one bot, so towards the end, we will likely be having grudge matches to fill time.
  5. No late hits. If the other bot is disabled, ask before you hit them again. Basically be polite.
  6. Have fun, play safe.


There will be a test box available for use throughout the day (thank you NHRL!) Please use it for any testing.



The Ruff:

These rule apply ONLY to the 3d printed plastic ant class at the Oct 2023 event.

Brackets will be by team and NOT by bot. This means each team may bring as many bots as they wish, but once the TEAM has lost twice they are eliminated from the tournament. 

Entry fee will be per bot. If you believe your bots are unique, then each must pay an entry fee. If you have questions, ask BEFORE the event. (Everyone will be busy at the event)

This double elimination tournament by team, not by bot. (This means that is you bring 4 bots, you pay 4 bots and can fight until your team loses twice.)

Please print two team tokens.  These will be surrendered to the winner of a match, as a prize.

Round 1: Grudge matches. Both team must agree to the match.  All other matches will be randomly generated.

All further rounds are by normal bracket matches. The first match will, immediately after the drivers meeting, engage the Mechanism of Randomness and have 5 minutes to prepare their robot. All subsequent matches will engage the Mechanism of Randomness when they are on deck. Their 5 minutes to prepare for their match will start when the in the arena match starts.


Mechanism of Randomness: 

The Mechanism of Randomness will be used to randomly select a "Fun" item. Someone, randomly selected from the spectators, will engage the Mechanism of Randomness. The result will apply to both teams.


"Fun" items:

- Drive with radio facing away from you and upside down (Control sticks towards the floor, and antenna towards the driver.  Pistol grip will point the front of the radio at the driver, use their thumb to control the throttle trigger, and their left hand to control the steering)

- Drive with mittens on your control hands

- Swap controllers and bots with opponent.  If you win, the win counts for your team.

- Add a toaster to your robot 

- Drive blindfolded (Verbal assistance from a team mate/crowd is allowed)

Toaster rules

- Toaster can not be permanently attached.  No glue, welding, etc

- Toaster can be attached via duck tape, zip ties, or hope.

- Bonus control points for Toaster taking no damage and being maintained on bot

- Extra damage points will be awarded for damaging the opponent's Toaster.


If you have questions about the rules, please feel free to ask via Discord or email the event organizer.
