The second Team UDAR hosted Michigan combat robot event! Michigan MASHUP combat robot event builds on our previous success ! Been waiting for a combat robot event in Michigan these days? Michigan Mashup is here! Thank you, and hope to see you there.


Michigan Mashup 11.06.21


Michiganders and neighbors! We’ve got the combat event for you!

Event Details:

Event is once again hosted in the small town of Bloomingdale at a local telecommunications company. There’s a reasonable amount of space with tables and chairs provided.


September 30, 2021 – November 05, 2021


COVID Considerations:

Masks are recommended but not required at this event.

Weight Classes:

A $20 fee will be collected per antweight and $10 per fairyweight to help cover arena and venue costs. I am asking that each driver only register 2 bots per class initially to allow others in that would like to compete, however, feel free to add more if the classes are not full in the last week before the event.

Robot Class Entry Fee Slots
Fairyweight (150g) $10.00 16
Antweight 1lb $20.00 25


The fairyweight class will be starting out the event and will take up the majority of the morning. I am tentatively hoping to start the fairyweight (150g) combat robot class by 10:30am, but it may possibly be later if setup takes longer than expected. You must have any bots that plan to compete signed in by 10 am so I can get the brackets built. Antweight class will probably begin near the end of the fairyweight finals.

The event will run as long as necessary but I am hoping to have it wrapped up by 5:00pm.

  • 9:00 – 10:00am – Event begins, check-in
  • 10:30am – Fights begin
  • 5:00pm- End of Event


  1. This time around we have a dedicated judge that has the job of watching very closely and making sure the right call is made. Judging guidelines:
  2. Both the 150g (fairy weight) and 1 pound (Antweight) classes will be operated under the SPARC Match Rules v1.2.This ruleset can be found here for review:
  3. While spark ruleset generally calls for unsticks to be allowed, a lot of arena upgrades have been made to ensure that robots don’t get stuck on the arena again. Thus the only unsticks that will be allowed are if the robots get stuck on each other.
  4. All robots must fit inside of a 12″ x 12″ 12″ cube.
  5. If magnets are used on your robot it must have less then 1 pound of added downforce for antweights and 150g for fairyweights. At check in robots with magnets will be required to show that they cannot stick to the bottom side of a metal plate.


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

  1. There will be a basic looking over of your robot at check-in time to make sure it has a locking device.
  2. You are expected to have confirmed that it will failsafe before arriving at the competition. To be clear, we will not be doing a failsafe check for every robot at the competition, you are expected to have done these before arrival.
  3. Failure to follow safe handling or if a robot does not failsafe during the competition may result in disqualification without fee reimbursement.

Arena and Hazards:

Arena is 4′ x 4′ x 2′ and consists of steel floor and 1/4 thickness of polycarbonate on all transparent portions of the arena. The arena also includes an auger hazard running from match start on one side of the combat area and a push-out zone which will become active in the last 60 seconds of the match on the other side.

Auger will reverse after a 10-second hold if it becomes jammed up by a robot, if the robot is still jamming up the augers after reversal the robot will be counted down.



You will be required to bring your own extension cords and any equipment that is necessary for the repair and operation of your robots.

Tournament Style:

Tournament style will be double elimination with small trophies awarded to the top 3 bots in each class.

If time allows a bot brawl including any driver that wants to be included from both groups will be held at the end of the day.


Spectators are welcome but those that are not associated with a competing team will be asked to pay a $5 dollar admittance fee for their group (unlimited group size for $5 entrance fee)

Everyone who attends the event will be expected to sign a basic waver before the competition begins.

In Closing:

Want to compete but don’t know how to get started? Check out this very basic article on getting going. The Naked Viper kit is designed to supply all of the electronics and mechanicals, other than the chassis, for antweight bots. You’ll also need a transmitter/receiver combo like this, and probably a battery charger like this.
