NVIDIA's Isaac GR00T N models are now integrated with Hugging Face’s LeRobot platform as part of the LeRobot 0.4.0 release, representing a significant collaboration between NVIDIA and the LeRobot team. This integration simplifies the process for the open-source robotics community to post-train and evaluate GR00T N1.5 models directly through LeRobot, effectively bridging the gap between disparate codebases and hardware interfaces. The update includes a unified API for model comparison, compatibility with standard LeRobot pipelines, and the ability to control real robots like the Reachy 2 and SO-101 through LeRobot’s drivers. This integration enhances performance, community reach, customization options, and streamlines processes such as data collection, fine-tuning, and deployment. With improvements in installation and dependency management, the platform now supports a modular policy and dataset API, allowing for seamless experimentation and deployment in both simulated and real-world environments.
