# OpenX to LeRobot
|
|
|
|
Open X-Embodiment assembles a dataset from 22 different robots collected through a collaboration between 21 institutions, demonstrating 527 skills (160266 tasks). (Copied from [docs](https://robotics-transformer-x.github.io/))

|
|
## 🚀 What's New in This Script
|
|
|
|
In this dataset, we have made several key improvements:
|
|
|
|
- **OXE Standard Transformations** 🔄: We have integrated OXE's standard transformations to ensure uniformity across data.
|
|
- **Alignment of State and Action Information** 🤖: State and action information are now perfectly aligned, enhancing the clarity and coherence of the dataset.
|
|
- **Robot Type and Control Frequency** 📊: Annotations have been added for robot type and control frequency to improve dataset comprehensibility.
|
|
- **Joint Information** 🦾: Joint-specific details have been included to assist with fine-grained understanding.

## Installation
|
|
|
|
1. Install LeRobot:
|
|
Follow instructions in [official repo](https://github.com/huggingface/lerobot?tab=readme-ov-file#installation).
|
|
|
|
2. Install others:
|
|
For reading tfds/rlds, we need to install `tensorflow-datasets`:
|
|
```bash
|
|
pip install tensorflow
|
|
pip install tensorflow-datasets
|
|
```
|
|
|
|
|
|
## Get started
|
|
|
|
1. Download source code:
|
|
|
|
```bash
|
|
git clone https://github.com/Tavish9/any4lerobot.git
|
|
```
|
|
|
|
2. Modify path in `convert.sh`:
|
|
|
|
```bash
|
|
python openx_rlds.py \
|
|
--raw-dir /path/to/droid/1.0.0 \
|
|
--local-dir /path/to/LEROBOT_DATASET \
|
|
--repo-id your_hf_id \
|
|
--use-videos \
|
|
--push-to-hub
|
|
```
|
|
|
|
3. Execute the script:
|
|
|
|
```bash
|
|
bash convert.sh
|
|
```
|
|
|
|
