## RoboAtom-Data

Time-aligned atomic-action annotations: each segment has a skill label, an action description, and frame boundaries. Each dataset has one JSONL file; `roboatom_data.jsonl` is their concatenation.

| Dataset | Annotation file |
| --- | --- |
| Private | [Private.jsonl](https://huggingface.co/datasets/InternRobotics/RoboAtom/resolve/main/RoboAtom-Data/by_dataset/Private.jsonl) |
| EBench | [EBench.jsonl](https://huggingface.co/datasets/InternRobotics/RoboAtom/resolve/main/RoboAtom-Data/by_dataset/EBench.jsonl) |
| Galaxea Open-World | [Galaxea_Open-World.jsonl](https://huggingface.co/datasets/InternRobotics/RoboAtom/resolve/main/RoboAtom-Data/by_dataset/Galaxea_Open-World.jsonl) |
| InternData-A1 | [InternData-A1.jsonl](https://huggingface.co/datasets/InternRobotics/RoboAtom/resolve/main/RoboAtom-Data/by_dataset/InternData-A1.jsonl) |
| LIBERO | [LIBERO.jsonl](https://huggingface.co/datasets/InternRobotics/RoboAtom/resolve/main/RoboAtom-Data/by_dataset/LIBERO.jsonl) |

| **All datasets** | [roboatom_data.jsonl](https://huggingface.co/datasets/InternRobotics/RoboAtom/resolve/main/RoboAtom-Data/roboatom_data.jsonl) |

```bash
hf download InternRobotics/RoboAtom --repo-type dataset \
  --include 'RoboAtom-Data/roboatom_data.jsonl' --local-dir ./data
```

```python
from datasets import load_dataset

annotations = load_dataset(
    "InternRobotics/RoboAtom", "RoboAtom-Data", split="train", streaming=True
)
```

| Fields | Meaning |
| --- | --- |
| `id`, `dataset`, `task_id`, `episode_index` | Trajectory and task identities |
| `task`, `task_flags` | Task text and task-text flags |
| `num_frames`, `fps`, `views`, `domain` | Frame count, FPS (InternData-A1: 30 mapped to 15), camera names, real/sim |
| `segments` | Ordered `{start_frame, end_frame, skill, action_text}` |
| `is_human_annotated` | Human-QC status: `true`, `false`, or `null` |
| `public_source_url`, `public_location` | Source repository and source-relative path, or `null` |

Frame indices are zero-based and both endpoints are included. The files contain annotations only; get videos and sensor data from the source datasets.

Skills: `Pick`, `Place`, `Handover`, `Move`, `Open`, `Close`, `Push`, `Pull`, `Press`, `Rotate`, `Screw`, `Plug`, `Pour`, `Fill`, `Scoop`, `Stir`, `Dip`, `Shake`, `Fold`, `Tie`, `Wipe`, `Sweep`, `Wash`, `Brush`, `Cut`, `Peel`, `Strike`, `Scan`, `Throw`. An empty `skill` marks an unlabeled span.

## RoboAtom-Bench

A model predicts ordered skill labels, action descriptions, and temporal boundaries for complete robot trajectories.

| Subset | Trajectories | GT segments | Videos |
| --- | ---: | ---: | ---: |
| Short (1–4 segments) | 200 | 411 | 200 |
| Medium (5–8) | 100 | 634 | 100 |
| Long (9–62) | 100 | 2,302 | 100 |
| Multiview | 100 | 671 | 321 |
| **Total** | **500** | **4,018** | **721** |

```bash
hf download InternRobotics/RoboAtom --repo-type dataset \
  --include 'RoboAtom-Bench/**' --local-dir ./data
```

`benchmark.jsonl` holds model inputs and relative video paths; `gt.jsonl` holds `action_config` segments with the same `benchmark_id`. An input record:

```json
{
  "benchmark_id": "benchmark:004957f135e186fb5052",
  "category": "short",
  "dataset": "RoboMIND 2.0",
  "task": "Transfers the tape from the board to the tray using both arms.",
  "fps": 30.0,
  "length": 242,
  "frame_interval": "closed_inclusive",
  "benchmark_view_mode": "singleview",
  "evaluation_views": ["front"],
  "model_view_key": "front",
  "views": {"front": "videos/004957f135e186fb5052/00_front.mp4"}
}
```

Validate, run inference, and score with the [RoboAtom code](https://github.com/InternRobotics/RoboAtom#quick-start-benchmark):

```bash
roboatom evaluate \
  --gt ./data/RoboAtom-Bench/gt.jsonl \
  --benchmark-input ./data/RoboAtom-Bench/benchmark.jsonl \
  --prediction outputs/roboatom_predictions.jsonl \
  --protocol configs/roboatom_bench.yaml \
  --output-dir outputs/roboatom_evaluation
```

Metrics: Micro F1 at 0.3/0.5/0.7, Skill F1@0.7, mIoU, and Edit.
