Nvidia Launches Medical Robot-Specific Physical AI Platform at GTC 2026, Including Dataset and Model Family

Nvidia announced the launch of the first domain-specific physical AI platform for medical robots at GTC 2026, including the Open-H dataset, Cosmos-H open model family, GR00T-H VLA model, and Rheo development blueprint.

The Open-H dataset has 776 hours of surgical videos covering 11 robot system instances and 4 surgical indications. Cosmos-H supports evaluating medical robot decisions via prompts, images, and videos; GR00T-H converts text commands for clinical tasks into action tokens; Rheo creates physically accurate hospital environment simulations. Currently, Open-H, Cosmos-H, and GR00T-H are available on GitHub and Hugging Face for developers to train and adapt to specific surgical scenarios.
