Isaac Gr00t N1 of NVIDIA represents a quantum leap in humanoid robotics, combining the avant -garde with open source accessibility. As the world's first open base model for generalized humanoid reasoning, this technology allows robots to interpret language commands, process visual data and execute complex manipulation tasks in various environments.
Desglosse of technical architecture
Double system cognitive framework
- System 1 (fast thinking): It acts as a fast thinking action model, similar to human reflexes and intuition. It was trained in data collected through human demonstrations and synthetic data generated by the Nvidia Omniverse platform.
- Process shares at 30Hz for real -time response capacity
- Built on the architecture of the diffusion transformer
- Trained in more than 6,500 hours of human demonstration data/robots
- System 2 (slow thought): It works as a deliberate model of action and action planning, promoted by a vision language model. Interpret the environment and instructions to plan actions, which are then executed by system 1 as precise and continuous movements.
- Vision-Langua Model (VLA) with parameters 2b
- Process multimodal entries through clip style encoders
- Allows contextual understanding and long -term planning
This architecture allows humanoid robots to make a wide range of tasks, from the basic manipulation of objects to complex activities of several steps that require sustained contextual understanding.
