Robotics Combat Event

Wisconsin Robotic Combat 09.26.21

WRC is back for our second event! The first one was about as successful as it could have been for being my first event and held out of a garage, but I can say with certainty this event will be much more streamlined. Presented by Betz Botz.


Wisconsin Robotic Combat 09.26.21


The Wisconsin Robotic Combat events are new events by a new league to help fill in the gaps left by COVID. WRC believes that holding events such as these helps encourage engineering and build the sport. We hope that you can support us. We’re building a new arena that isn’t a shelf found on the side of the road too! All are welcome, please join us.

Event Details:


UPDATE: We have a lot of entries and a very expensive arena, so the highest bidder will be taking the first open spot in either weight class. I’ll email the highest bidder and only accept their entry for the event if a spot does open up. Please email me with the price and I’ll add you to the waitlist here if you’re interested.

The fundraising link for the arena expansion is here:

The event is being held at MSOE’s STEM Center which is being opened up for this event through the Milwaukee Makerfaire:

From my understanding, we’ll be right next to the FIRST Robotics kids to completely steal the show. At this moment I’m still working out details about parking, pit access, and Makerfaire access in general.

Wisconsin Robotic Combat Event Registration:

Registration will be open from 7/31/21 to 9/25/21.



WRC COVID Considerations:

IMPORTANT COVID-19 UPDATE: The partnership between MSOE and the Milwaukee Makerfaire has caused a policy that to attend the event you must have a negative COVID-19 test within 3 days of the event OR be vaccinated for COVID-19. This policy applies to anyone over 12yrs of age or older. Masks will also be required for anyone 2yrs of age or older regardless of vaccination status. I know these policies are inconvenient for some of you, but it’s a very large event and they’re just trying their best. For any questions related to this you’re probably better off contacting the Milwaukee Makerfaire.

You can find the university’s COVID Dashboard and announcements here.

Weight Classes:

Please see the table for entry fees by robot class. There is no cost for spectators.

Robot Class Entry Fee Slots
Antweight (1lb) $30.00 16
Plastic Antweight 1lb $30.00 16
Beetleweight 3lb $30.00 8


This could change depending on the Makerfaire but here’s the current schedule plan.

  • 8:00am-9:45am – Setup and check-in
  • 9:45am-10:00am – Driver’s meeting and first fight queueing
  • 10:00am-2:00pm – Main fights
  • 2:00pm-3:00pm – Finals, plastic ant demos, rumbles
  • 3:00pm-? – Awards and cleanup


Both classes opperate under the SPARC ruleset. For the plastic class I think cardboard is a fair addition to the traditional PET, PETG, ABS, PLA, or PLA+ and I will allow it.

We all know that “Just 5 more minutes!” means your robot is in four pieces. I will try to be as reasonable as I can with delays and repair times early in the tournament, but I can only guarantee 20mins and one potentially short delay past that. In the last event, we had some issues with 45min+ repair times, and the 20min rule wasn’t enforced because we wanted good finals fights. I will forfeit people this time because this is an event with spectators and a 5hr time slot. It’s not my fault if you don’t design a combat robot of all things for serviceability. 😛

An important note about unsticks because of a particular antweight: If you embed yourself in the arena, aka become immobile by causing damage to something that should be assumed indestructible, you are granted one unstick per match. This is different from getting propped up against a wall, doing the thing, or becoming stuck on a piece of debris from another robot. If a piece of debris detaches from the arena during a fight and causes you to get stuck, you are allowed one unstick because this wouldn’t have happened with an indestructible arena.


All bots will be required to pass a safety check verifying the following:

  1. All robots must failsafe.
  2. All bots must have appropriate weapon locking.
  3. We will have a little meeting before we actually get going to go over some basics so everyone is on the same page.

Arena and Hazards:

Arena: Wood floor, thin steel kickplates which could end up being ablative, and a lipped pushout so a deliberate push is required for a win. 8’ x 6’ x 4’ box.


Tournament Style:

Open Ant: Double elimination tournament with 2 minute fights.

Beetle: Double elimination tournament with 2 minute fights.

Plastic Ant: We’re just demoing plastic ants in the hope to run a two-day event next year with 150g and plastic ants on day one for the local builders. These are here to put on a show and fill space as the tournament winds down so people have time to rebuild. If we get all 8 spots filled I’ll have 4 fight-card-style fights set up. These will be handpicked, 3-minute matches for the best fights possible. I would also encourage builders to have their plastic ants ready to go on display upfront; if someone is willing to talk about the 3D printing in said robots we can connect with a huge group of potential builders at the Makerfaire.


The time slot for spectators is 10:00am-3:00pm.
