NVIDIA Isaac GR00T FAQ
Quick answers, plain wordsIs Isaac GR00T free?
Yes, it can be downloaded at no charge. Code is under Apache 2.0 and the weights use NVIDIA's open model license.
What hardware do I need?
Inference needs one GPU with at least 16 GB of VRAM. NVIDIA recommends GPUs with 40 GB or more for fine-tuning.
Can I adapt it to my own robot?
Yes. The repository describes fine-tuning for custom robots using a new embodiment configuration and LeRobot-style data.
