The physical world closes the loop
An embodied system perceives, decides, acts and observes the consequences. Every action changes the next input, so timing, uncertainty and recovery are central.
World understanding becomes operational
Concepts such as inside, behind, reachable, fragile, hot and blocked determine whether a plan is physically executable.
Actions need continuous control
Motors and balance require fast feedback. Modern architectures combine or separate slower reasoning from high-frequency control.
Foundation models move into robotics
Gemini Robotics, GR00T and Helix all point toward reusable learned skills that connect perception, reasoning and movement instead of a hand-coded program for every object.
Embodiment changes responsibility
When AI can move furniture, operate appliances or enter private rooms, software failures become physical and privacy consequences expand.
