Rohan Paul@rohanpaul_ai · X李飞飞重新定义机器人学，强调其核心是“空间智能”——即机器在三维物理空间中感知、理解与行动的能力。这一能力使机器人能执行任务并实现人机协作。3D生成与重建技术正打破人类仅能体验单一物理世界的局限，创造出用于训练、创造、旅行与社交的无限数字多元宇宙。未来，人们将以“多元宇宙”的方式生活，极大拓展人类想象与交互的边界。
Fei-Fei Li （ @drfeifei ） beautifully explains Robotics.
She defines robotics not by form， like humanoids or cars， but by function： they are any "embodied machines" that must perceive， understand， and act within a physical， 3D space.
This core requirement is "spatial intelligence，" the unifying principle of all robotics， allowing them to perform tasks and even collaborate with humans.
Throughout all of human history， we have been confined to a single， shared reality： the "physical Earth 3D world."
This singularity has been our only playground.
However， new technologies that combine 3D generation and reconstruction are shattering this limitation.
We can now create "infinite universes"-a multiverse of digital worlds for countless purposes， from training robots to enabling creativity， travel， and storytelling.
