The GEAR team focuses on developing embodied AI agents that act in both virtual and physical realms, emphasizing the creation of advanced AI brains for humanoid robots. NVIDIA's competitive edge lies in its substantial compute resources essential for scaling foundation models and its rich history in graphics and simulation, which facilitates physics simulation and real-time GPU acceleration. The team's strategy diverges from the industry's preference for real-world data, opting instead to leverage simulation techniques to enhance robotics development.
AI researcher Jim Fan has had a charmed career. He was OpenAI’s first intern before he did his PhD at Stanford with “godmother of AI,” Fei-Fei Li. He graduated into a research scientist position at Nvidia and now leads its Embodied AI “GEAR” group. The lab’s current work spans foundation models for humanoid robots to agents for virtual worlds.
Jim describes a three-pronged data strategy for robotics, combining internet-scale data, simulation data and real world robot data. He believes that in the next few years it will be possible to create a “foundation agent” that can generalize across skills, embodiments and realities—both physical and virtual. He also supports Jensen Huang’s idea that “Everything that moves will eventually be autonomous.”
