# roller-es13

2 m Roller Sprint skater: Pollen roller reference fine-tuned by evolution strategies on the Arena roller scorer, searched on x86 (thirteenth round).

A **perpetual** policy for the [microduck](https://github.com/pollen-robotics/microduck) (61-D observation, 14 actions, 50 Hz, on rollers). Runs until told otherwise — a gait, loaded into a policy slot.

## Run it on a robot

```bash
sudo robotctl policy load <slot> juicenv/microduck-roller-es13
```

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).

A remix of [pollen-robotics/microduck-roller-sprint-2m-reference](https://huggingface.co/pollen-robotics/microduck-roller-sprint-2m-reference).
