What happened
Jim Fan shares uncut, 1x-speed video of GR00T 2 controlling dexterous hands to perform a chemistry lab experiment and clean up afterward. He describes it as the first episode in a series of real-time robot videos, without the speed-up labels he says are usually shown.
Why it matters
The uncut, real-time footage shows GR00T 2 completing a chemistry lab experiment and cleanup with dexterous hands, making the sequence of the demonstration directly observable.

Episode 1 of a new series! I’ll keep dropping real-time robot videos, with none of the “4x” or “8x” labels you usually see in the corner. No one can speed up reality, except Dr. Strange ;)
View the quoted post on XIntroducing GR00T 2: our most advanced, open System One model for robotics. It runs entirely on your robot’s onboard compute, fully untethered, and you own every weight of it. GR00T 2 features:
- Long-horizon tasks: dexterous manipulation and whole-body control chained over 20+ steps and 5+ minutes, such as performing chemistry lab experiments or assembling model airplanes end to end.
- X-Adapt: adapting from easy data sources (human wearables and simulation) and deploying zero-shot to diverse real robots.
- Unified Cognition: native integrations with frontier agents for advanced physical reasoning, robust error recovery, and safety monitoring.
It's an open-source buffet! We are releasing not only the model weights and X-Adapt recipes (coming December), but also our agentic framework, simulation engine, annotation engine, hardware design, and even training data (100K hours, that's ~11 yrs of experience), all available today!
Everything that moves will be autonomous. Anyone can become a roboticist.
Lock in, build with us!

The story so far
NVIDIA introduced GR00T 2 as an open robotics model designed to run on a robot’s onboard compute, and Jim Fan later shared a video of it controlling dexterous hands through a chemistry experiment and cleanup. Fan described the footage as autonomous, uncut, and shown at real-time speed. Fan said GR00T 2 handles tasks spanning more than 20 steps and five minutes, and that X-Adapt can use human-wearable and simulation data to adapt it for zero-shot deployment on different real robots. NVIDIA says the model weights, agentic framework, simulation and annotation engines, hardware design, and 100,000 hours of training data are available now; X-Adapt recipes are expected in December.
