Nvidia has announced Groot N1, its latest AI foundation model for humanoid robotics, at the GTC 2025 conference in San Jose. This 'generalist' model utilizes a dual system architecture inspired by human cognitive processes, enabling robots to reason and execute complex actions. Building on last year's Project Groot, Groot N1 expands its focus to diverse humanoid robot applications. The model is available as open source, accompanied by simulation frameworks and synthetic training data blueprints. As humanoid robotics advances, companies like X1 and Figure aim for mass production despite significant challenges.
