First rule of DuckFightClub: you don't quack about it.

Eight teams train MicroDuck policies, launch them into the simulator, and fight best of 3 until one program becomes the QuackDown Champion.

The fighters

Real robot energy. Virtual damage.

MicroDuck is the visual muse; the arena action is simulator-native, policy-driven, and built for livestream drama.

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 virtual circular fight surface with a high-contrast boundary, reproducible spawn positions, standard physics settings, and sponsor-visible broadcast overlays.

01

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

02

Each bout is best of 3 simulated rounds.

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 match. 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. The event is played in the MicroDuck simulator so teams can 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 is built as a broadcast-first simulator event with match cards, replays, overlays, and sponsor placements.

Can people sponsor the arena?

Yes. Sponsors can appear on virtual arena walls, stream overlays, replay frames, walkout cards, and bracket segments.

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.
