# DROID Skill Subset: scooping

This is a skill-filtered subset of the local DROID 1.0.1 LeRobot-format dataset.
It was generated with `droid_filter.py` from `/scratch/jellyho/prsl_skills`.

## Repository

- Hugging Face repo: `jellyho/droid_subsets_scooping`
- Source dataset path used locally: `/scratch/jellyho/droid_1.0.1`
- Output subset path used locally: `/scratch/jellyho/droid_subsets/scooping`

## Filtering

```json
{
  "skills": [
    "scooping"
  ],
  "skill_keywords": {
    "scooping": [
      "scoop up",
      "to scoop",
      "scoop some",
      "use the spoon to",
      "spoon to take",
      "spoon to get",
      "spoon to transfer"
    ]
  },

  "min_length": null,
  "max_length": null,
  "max_episodes": 300,
  "sample_mode": "balanced",
  "seed": 0
}
```

## Dataset Statistics

- Episodes: `300`
- Frames: `147394`
- Unique tasks: `300`
- Sampling mode: `balanced`
- Max episodes: `300`
- Seed: `0`
- Mean episode length: `491.31333333333333`
- Min/max episode length: `88` / `1239`
- Episode success rate: `1.0`

## Preserved Action Fields

Filtering only selects episodes/rows. It does **not** drop action-space columns.
The following action columns are preserved from the original DROID parquet files:

```text
action.gripper_position
action.gripper_velocity
action.cartesian_position
action.cartesian_velocity
action.joint_position
action.joint_velocity
action.original
action
```

`action` is the compact 8D policy action used by LeRobot-style loaders. The
additional `action.*` columns remain available in the parquet files for
inspection or custom loaders.

## Top Tasks

| task_text | episodes |
| --- | --- |
| Use the spoon to place some coffee beans from the red bowl in the clear jug. | 1 |
| Move the black pot to the right then use the spoon to take some contents out of the pot | 1 |
| Scoop up the beans from the bowl on the right and put them to the bowl on the left | 1 |
| Use the silver spoon to get some coffee beans from the container and put them on the small white plate. | 1 |
| Use the spoon to scoop some of the contents in the white bowl into the glass on the right | 1 |
| Use the silver spoon to scoop some of the contents in the bowl into the glass cup | 1 |
| Use the spoon to transfer beans to the bowl on the left | 1 |
| Use the spoon to scoop some beans from the red bowl and put them in the pot | 1 |
| Use the spoon to move some of the brown objects to the other bowl | 1 |
| Put the orange objects on the silver spoon then use the spoon to place the objects in the small measuring cup. | 1 |

## Files

This repository keeps the LeRobot-style layout:

```text
meta/info.json
meta/tasks.parquet
meta/episodes/chunk-000/file-000.parquet
data/chunk-000/file-*.parquet
episodes.csv
episodes.jsonl
summary.json
stats.json
task_counts.csv
length_histogram.csv
source_episode_files.csv
```

The subset keeps compact `episode_index`, `task_index`, and `index` values for
loader compatibility. `episodes.csv` keeps `original_episode_index` for tracing
rows back to the original DROID dataset when available.

## Notes

Video files are not included unless explicitly materialized with video symlinks
or copies. These subsets are intended for lightweight skill-conditioned
fine-tuning experiments.
