# Physical AI Foundation Models for Robotics

In robotics, Artificial Intelligence (AI) models are the "brains" that enable machines to perceive, understand, predict, and act within their environments. Modern robotics has moved beyond simple pre-programmed instructions, now leveraging sophisticated AI models that allow for unprecedented levels of autonomy and adaptability. This entry outlines the key categories of AI models forming the contemporary robotics stack: **Foundation Vision Models, World Models, and Vision-Language-Action (VLA) models.**
