NVIDIA Isaac GR00T N1.7 is an open foundation model for generalized humanoid robot reasoning and skills. This cross-embodiment model takes multimodal input, including language and images, to perform manipulation tasks in diverse environments. Developers and researchers can post-train GR00T N1.7 with real or synthetic data for their specific humanoid robot or task.
Isaac GR00T N1.7 is the medium-sized version of our model built using pre-trained vision and language encoders, and uses a flow matching action transformer to model a chunk of actions conditioned on vision, language and proprioception.
A detailed description of the Isaac GR00T N1.X architecture is provided in the GROOT N1 White Paper (https://arxiv.org/abs/2503.14734).
This model is ready for commercial/non-commercial use.

The schematic diagram is shown in the illustration above.
Red, Green, Blue (RGB) camera frames are processed through a pre-trained vision transformer (SigLip2).
Text is encoded by a pre-trained transformer (T5)
Robot proprioception is encoded using a multi-layer perceptron (MLP) indexed by the embodiment ID. To handle variable-dimension proprioception, inputs are padded to a configurable max length before feeding into the MLP.
Actions are encoded and velocity predictions decoded by an MLP, one per unique embodiment.
The flow matching transformer is implemented as a diffusion transformer (DiT), in which the diffusion step conditioning is implemented using adaptive layernorm (AdaLN).
Input Format:
-Vision: Variable number of uint8 image frames, coming from robot cameras
-State: Floating Point
-Language Instruction: String
-Embodiment ID: Integer indicating which of the training embodiments is observed
Other Properties Related to Output: Continuous-value vectors correspond to different motor controls on a robot, which depends on Degrees of Freedom of the robot embodiment.
