# X2Real Dataset
Fine-tuning datasets used in the experiments of the X2Real technical report, *X2Real: An eXtensive Simulation Benchmark for Real-World Generalist Policies*.
The repository contains four self-contained datasets in the validated LeRobot v2.0 format. Choose the embodiment and control space required by your experiment.
## Dataset variants
| Path | Setting | Control space | State/action dimension | Episodes | Frames | Rate |
| --- | --- | --- | ---: | ---: | ---: | ---: |
| `data/x2real-desktop-ee-lerobot-v2` | Desktop simulation | End effector | 20D | 10,491 | 4,066,988 | 20 fps |
| `data/x2real-desktop-joint-lerobot-v2` | Desktop simulation | Joint | 14D | 10,491 | 4,066,988 | 20 fps |
| `data/x2real-mobile-ee-lerobot-v2` | Mobile manipulation | End effector + mobile body | 26D | 3,069 | 4,260,099 | 20 fps |
| `data/x2real-mobile-joint-lerobot-v2` | Mobile manipulation | Joint + mobile body | 20D | 3,069 | 4,260,099 | 20 fps |
Each variant includes three camera streams: front view, left wrist, and right wrist. Field definitions, coordinate conventions, task information, and known limitations are documented in the README inside each dataset directory.
## Repository layout
```text
X2Real-Dataset/
├── README.md
├── scripts/
│ └── download_x2real_dataset.py
└── data/
├── x2real-desktop-ee-lerobot-v2/
├── x2real-desktop-joint-lerobot-v2/
├── x2real-mobile-ee-lerobot-v2/
└── x2real-mobile-joint-lerobot-v2/
```
Every directory under `data/` is an independent LeRobot v2.0 dataset root containing its own `README.md`, `checksums.sha256`, `meta/`, `data/`, and `videos/`.
## Download
Install the Hugging Face client:
```bash
pip install -U huggingface_hub
```
Download one variant:
```bash
python scripts/download_x2real_dataset.py desktop-ee --output ./X2Real-Dataset
```
Use `desktop-joint`, `mobile-ee`, `mobile-joint`, or `all` in place of `desktop-ee`. The selected dataset is written under `OUTPUT/data/` without changing its LeRobot layout.
To verify a downloaded variant:
```bash
cd data/x2real-desktop-ee-lerobot-v2
sha256sum -c --quiet checksums.sha256
```
The repository root is a container for four schemas, not a single LeRobot dataset root. Point LeRobot tooling at one directory under `data/`.
