Pro wrestling for reinforcement-learning ducks.

First rule: you don't quack about it.

The fighters

Real robot energy. Virtual damage.

Every fighter starts as the same 25 cm open-source duck. What turns it into a contender is the policy — born cute, trained in the sim, sent to sumo for the belt.

01

Meet

The MicroDuck squad in several colorways

A 25 cm open-source duck family. Looks harmless. Waddles.

03

Fight

A MicroDuck squared up in the sumo ring, dust flying under the lights

Best of 3 in the simulator. Last duck standing takes the Golden Beak Belt.

The bracket

8 teams. No byes. One belt.

A tighter card keeps the stream moving: four quarterfinals, two semifinals, and one final. Every team starts on equal footing.

Rules of the sim

Robot sumo without robot bruises.

The ring is a plain circle with a hard, high-contrast edge. Same spawn spots and the same physics every match, plus room on the boards for sponsors.

01

Every fight runs in the MicroDuck simulator, not with physical robots.

02

Each bout is best of 3 rounds — first policy to win 2 takes it; a 1:1 split goes to a decider.

03

A round is won when the opposing policy drives, trips, or gets pushed out of the circle.

04

Submitted policies must run at event settings and use the approved control interface.

05

Referee reset only for simulator faults, deadlocks, or unrecoverable spawn states.

Training camp

Policies are the fighters.

Write the policy

Teams write the controller that decides how their MicroDuck moves, balances, commits, feints, and recovers inside the simulator.

MicroDuck RL repo

Train in simulation

Reinforcement learning turns scrimmage time into pushing, dodging, edge awareness, and last-second save behaviors.

Freeze the build

Final policies are submitted before QuackDown so the livestream can run fair, reproducible matches.

The title

QuackDown Champion.

The winner gets the Golden Beak Belt: a ridiculous, glorious simulator-wrestling prize for the policy that owns the ring.

Golden Beak Belt for the QuackDown Champion

Golden Beak Belt

Awarded on stream after the final best of 3. The belt belongs to the team, but the bragging rights belong to the policy.

FAQ

Common questions before the stream.

What is DuckFightClub?

A livestreamed simulator fight club where MicroDuck control policies enter a robot sumo bracket and try to win QuackDown.

Are real robots fighting?

No — MicroDuck hardware isn't released yet. If we can get our hands on prototypes we'll fight them; until then the bouts run in the MicroDuck simulator, so teams compete with policies, not fragile hardware.

What is a MicroDuck?

MicroDuck is Pollen Robotics' 25 cm open-source biped robot, built for makers to train, retrain, and deploy learned behaviors.

How does training work?

Teams write their own control policies and can use reinforcement learning to train ring control, pushing, dodging, and recovery in simulation.

How does the bracket work?

Eight teams enter a single-elimination chart. Everyone starts in the first stage, so no team gets a bye and every policy has to fight its way to the belt.

What are the fight rules?

Best of 3. Stay in the circle, force the other policy out, and keep the controller inside the approved simulator interface.

Will it be livestreamed?

Yes. QuackDown streams live on YouTube (channel announced soon) and is built broadcast-first with match cards, replays, overlays, and sponsor placements.

Can people sponsor the arena?

Yes. Sponsors can own the mat center, a ring of apron boards, or the back-wall marquee that renames the whole event.

Can spectators bet on matches?

There is no cash betting. Friendly side wagers can use Codex or Claude quota, bragging rights, or other non-cash dev-world tokens. DuckFightClub does not operate a betting platform, hold wagers, or settle disputes. Quack responsibly.
