# roller-es21
2 m Roller Sprint skater: namenu/microduck-arena (strata-roller-pb4, 0.960 s) fine-tuned by ES and an elitist hill climb on the Arena roller scorer, searched on x86 (0.948 s). Credit to namenu.
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-es21
```
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 [namenu/microduck-arena](https://huggingface.co/namenu/microduck-arena).
