Advancements in AI robotics will hinge on developing models that excel at low-level motor control, akin to the effortless human ability to grasp and manipulate objects through intuitive understanding of verbs like 'open'. Current robotic systems struggle with generalizing these actions across various contexts. The future lies in creating robots that can abstractly comprehend actions and apply them flexibly in diverse situations, signaling a transformative moment in the field within the next few years.
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.”
