# backroll
Mjlab-GotATalent-MicroDuck
A **perpetual** policy for the [microduck](https://github.com/pollen-robotics/microduck) (61-D observation, 14 actions, 50 Hz). Runs until told otherwise — a gait, loaded into a policy slot.
## Run it on a robot
```bash
sudo robotctl policy load <slot> dashi/microduck-backroll
```
The observation normalizer is baked into `policy.onnx`; feed raw observations.
`manifest.json` follows schema 2 of the microduck policy manifest (`docs/policy-manifest.md` in the daemon repo).
## Training
- **task_id**: `Mjlab-GotATalent-MicroDuck`
- **repo**: `https://github.com/bxshi/microduck-challenges.git`
- **branch**: `HEAD`
- **commit**: `a15317f40`
- **checkpoint**: `1750`
- **seed**: `1`
- **base**: `mjlab-microduck 0.1.0 @ 8d0dbc94c`
- **started**: `2026-10-22T07:55:17Z`
## Reproduce
Same code, same `uv.lock`, same command, same seed. Training it again yields a comparable policy, not the same weights: GPU reinforcement learning is not bit-reproducible across machines.
```bash
git clone https://github.com/bxshi/microduck-challenges.git
cd microduck-challenges
git checkout a15317f40
uv sync
uv run train Mjlab-GotATalent-MicroDuck --env.scene.num-envs 4096 --agent.max-iterations 2500 --agent.seed 1 --agent.logger tensorboard --agent.run-name roll12c --agent.resume True --agent.load-run 2026-10-22_07-14-05_roll12 --agent.load-checkpoint model_500.pt
