This PR enhances the model card by:
- Adding the `pipeline_tag: robotics` to the metadata for better discoverability on the Hugging Face Hub.
- Adding explicit links to the paper (Hugging Face page), project page, and the GitHub repository.
- Including a detailed 'Sample Usage' section with code snippets adapted from the GitHub README.
- Correcting a typo in the arXiv link.
Please review and merge if these improvements are satisfactory.
