# LIBERO LeRobot v3

## Dataset Summary

`nvidia/LIBERO_LeRobot_v3` is a LeRobotDataset v3.0 conversion of the LIBERO robot manipulation benchmark. LIBERO is designed for studying lifelong robot learning and knowledge transfer across language-conditioned manipulation tasks. This repository packages the LIBERO task suites as LeRobot-compatible datasets with Parquet state/action data, MP4 video observations, and LeRobot metadata.

The dataset is organized as five top-level suite folders:

- `libero_spatial`
- `libero_object`
- `libero_goal`
- `libero_90`
- `libero_10`

Each suite is stored independently in LeRobotDataset v3.0 format.

## Dataset Details

### Dataset Description

LIBERO, short for LIfelong learning BEnchmark on RObot manipulation, is a benchmark for studying lifelong learning in decision-making and robot manipulation. It focuses on knowledge transfer across tasks involving spatial relations, object manipulation, goal changes, and long-horizon behavior.

This version converts LIBERO demonstration data to the LeRobotDataset v3.0 standard. LeRobot v3.0 uses file-based Parquet and MP4 shards plus structured metadata, replacing per-episode files with chunked files that can contain multiple episodes.

This dataset is ready for commercial or non-commercial uses.

## Dataset Format

The repository contains one LeRobotDataset v3.0 dataset per suite folder. Each suite follows the LeRobot v3 layout:

```text
<suite>/
├── data/
│   └── chunk-000/
│       └── file-*.parquet
├── meta/
│   ├── info.json
│   ├── stats.json
│   ├── tasks.parquet
│   └── episodes/
│       └── chunk-000/
│           └── file-*.parquet
└── videos/
    ├── observation.images.image/
    │   └── chunk-000/
    │       └── file-*.mp4
    └── observation.images.wrist_image/
        └── chunk-000/
            └── file-*.mp4
```

### Dataset Quantification

The following values are taken from each suite's `meta/info.json`.

| Suite | Episodes | Frames | Task IDs | FPS | Robot |
|---|---:|---:|---:|---:|---|
| `libero_10` | 379 | 101,469 | 10 | 20 | Franka |
| `libero_90` | 3,921 | 569,249 | 73 | 20 | Franka |
| `libero_object` | 454 | 66,984 | 10 | 20 | Franka |
| `libero_spatial` | 432 | 52,970 | 10 | 20 | Franka |
| `libero_goal` | 428 | 52,042 | 10 | 20 | Franka |
| **Total** | **5,614** | **842,714** | **113** | **20** | **Franka** |

Note: the upstream LIBERO task suite naming includes `LIBERO-90`; this converted repository's `libero_90/meta/info.json` reports 73 task IDs.

Total Data Storage: 4.5 GB

### Features

Common feature fields include:

- `action`: 7-dimensional robot action vector.
- `observation.state`: 8-dimensional robot state vector.
- `observation.images.image`: RGB video observation, 256 x 256, 20 FPS, AV1 MP4.
- `observation.images.wrist_image`: RGB wrist-camera video observation, 256 x 256, 20 FPS, AV1 MP4.
- `timestamp`, `frame_index`, `episode_index`, `task_index`, and `index`.

The `libero_90` suite additionally includes:

- `observation.states.ee_state`
- `observation.states.gripper_state`
- `observation.states.joint_state`

### File Format

- Tabular robot state/action data: Apache Parquet.
- Episode metadata: chunked Parquet under `meta/episodes/`.
- Task metadata: `meta/tasks.parquet`.
- Video observations: MP4 files under `videos/`.
- Dataset schema and statistics: `meta/info.json` and `meta/stats.json`.

## Loading

Because this repository contains multiple LeRobot datasets under top-level suite folders, select the suite you want to use and point your local LeRobot workflow at that suite directory.

Example: download a single suite from the Hub.

```python
from huggingface_hub import snapshot_download
from pathlib import Path

repo_dir = snapshot_download(
    repo_id="nvidia/LIBERO_LeRobot_v3",
    repo_type="dataset",
    allow_patterns=["libero_spatial/**"],
)

suite_dir = Path(repo_dir) / "libero_spatial"
print(suite_dir)
```

Use `suite_dir` as the local LeRobot dataset root in workflows that accept a local LeRobotDataset directory.

## Dataset Creation

### Source Data

The source data is derived from LIBERO, a benchmark for lifelong robot learning and language-conditioned robot manipulation. The LIBERO paper describes high-quality human-teleoperated demonstration data for the benchmark's tasks.

### Conversion

This repository converts LIBERO data into LeRobotDataset v3.0. In LeRobot v3.0, data and video frames from multiple episodes are grouped into larger shard files, while metadata records episode boundaries, task IDs, feature schemas, statistics, and path templates.

## Ethical Considerations

NVIDIA believes Trustworthy AI is a shared responsibility and we have established policies and practices to enable development for a wide array of AI applications. Developers should work with their internal developer teams to ensure this dataset meets requirements for the relevant industry and use case and addresses unforeseen product misuse.
