Atlanta Turnabot Turnament 1


Scott Siegel :


Get your battle fix in a few hours on a Saturday morning!


Loaner bots will be available! (Anyone can get a few matches completely free!)


*** This event is appropriate for ALL experience levels! There will be plenty of people that this is their first time doing anything with combat robots. There will also be several people that have been on BattleBots and have hundreds of matches under their belts.


Hook your friends with "easy" entry into the world of Combat Robots!


The goals of the Turnabot Turnaments (a 150g Sportsman / Safe / Non-Destructive Combat Robot League) include:

1. Develop a class where everyone can ENJOY Combat Robots as easily, cheaply, and safely as possible. 

2. Maximize battle time and minimize rebuild time

3. Promote the developement of bots that can safely battle in open air arenas, while still being fully competitive in Full-Combat 150g events.

    (As of 1/24/23 fully 7 of the top 10 150g Full-Combat bots are Sportsman / Non-Destructive!)

4. Create short-duration Turnaments that make it easy to bring friends and family that are not YET bot enthusiasts

5. Develop the supporting components to facilitate "Turnament" series in several cities


The plan is to run 4-6 events per year, possibly culminating in a "qualified championship" event.


At least the first 2 Atlanta events (3/11/23 and 4/22/23) will be at North Atlanta Church of Christ. There is a large room that has plenty of space for the 4 arenas and pit space for every team.

Event Structure:

The "Turnabot Turnament" event structure uses up to 4 TurnaboX arenas simultaneously to allow up to 32 competitors to battle through double-elimination to a single victor in about 2 hours of battle time. It also enables up to 34 grudge / practice matches for anyone that wants that extra battle time. Realistically an eager competitor can get 6 matches regardless of their results.

In order to complete up to 19 rounds, with as many as 96 matches, we will need to stay on a strict schedule. Please try to be "on deck" at your arena to watch and cheer on the previous competitors.

Doors will open at 9 am. Battling starts at 10 am and should finish near noon. We'll shoot to have awards and cleanup done by 1 pm.

TurnaboX Arenas:

Each TurnaboX Arena is made of high-quality coroplast with a 49" x 42" floor, 5" outer walls, 2 triangular lipped and "guarded" corner pits and 2 lipped square mid-floor pits. Another key to the success of these "easy and often" events is the use of these lightweight arenas. Please consider this when designing or selecting bots to reduce wear and tear on the arenas. Pics and details are available here: TurnaboX Link TurnaboX Pic

Match structure:

Matches begin with each bot touching their corner color zone and 5 scoring sticks in the wall protecting each corner pit.

After a 3-2-1-Activate the large clearly visible 3-minute countdown clocks starts. All 4 arenas start at the same time.

Each time a competitor gets their opponent into a pit they win a scoring stick. They can choose any stick in the box and place it into the wall behind their corner

If both bots go into the pit at the same time and there was a mutually-accepted clear aggressor, they win that point.

If the competitors do not agree then neither player scores and they can call for an official to watch the rest of that match.

There will only be a few floating officials, part of the success of this type of "easy" event is the general good sportsmanship of bot builders.

Both bots are immediately reset touching their color zones and both competitors say 3-2-1-Activate together.

This repeats until either one competitor has acquired 5 scoring sticks, or until the 3-minute buzzer sounds.

If the scores are tied at the 3-minute buzzer then that arena goes to sudden-death, the next pitter wins! (This will let everyone watch those ultimate final battles)

There will be roughly 2-minutes until the next match begins in each arena. This should allow at least 5 minutes between each bot's matches for the first 12 rounds.

After Round 12 there will no longer be a minimum of 1 round between each bot's matches so we'll add 5 minute "charge breaks / grudge matches" between Rounds 12 and 19. That's right, there will be 6 or 7 rounds of all 4 arenas available for grudge matches. We'll prioritize those who had the least matches so everyone that wants to should be able to get at least 4 matches in 2 hours! Again, a motivated person should be able to get 6 matches, even if they don't win any.


Given the goal of supporting a large number of competitors in a short amount of time, please ensure that in under 5 minutes you can either swap batteries or charge enough to make it through the next round. Turnabots for example can easily battle for 20+ minutes straight and a few minutes of charging between rounds is plenty to keep running for the whole turnament.

"Normal" rules:

The SPARC ruleset is a good place to start. Basics include, no liquid, no electrical weapons, no entanglement, etc.

For these events, obviously no cleated wheels or other things likely to damage the arenas. Excessively sharp forks are likely to get a bot stuck, which will count as a "pit" so design, build, and drive accordingly.

Regarding the "sportsman / non-destructive" rules:

The intent of this class to allow SAFE battling in open air arenas. The bots must have absolutely zero capability of hurting someone directly or by launching shrapnel. Not damaging other bots or the arenas is secondary to being safe. Even though the arenas are made of high-quality coroplast, please ensure your bot cannot do permanent damage to the arenas. A good test might be testing your bot against a strong cardboard box. When in doubt, please send questions, ideally with pics or video to the event organizer (EO). Understandably the bots must remain safe for the entire turnament. The EOs will always have the final determination on whether a bot is safe enough to participate in the competition.

Other rules:

Safety glasses are required for anyone near any moving bots. We will have some loaners available, but it would be good for everyone to bring some.

We will all need to ensure that we take care of the property. Soldering, heat guns etc need to be used either on concrete or solder mats.
