About Isaac GR00T
The NVIDIA Isaac GR00T Reference Humanoid Robot is the first open humanoid platform built for academic research. It combines a Unitree H2 Plus body, dual Sharpa Wave five-finger hands, NVIDIA's Jetson AGX Thor on-board AI compute, and the full Isaac GR00T software stack into one integrated system. Available from Unitree in late 2026 for research and university labs.
