physical AI
Physical AI refers to AI systems, such as robots and self-driving cars, that perceive the real world and act within it.
Unlike AI that only works with text or images, physical AI perceives its surroundings through cameras and sensors and takes physical actions through motors and mechanical parts. Humanoid robots, industrial robots, self-driving cars and drones are examples.
Because many situations are hard or dangerous to test in the real world, physical AI is often trained and validated first in virtual environments using physics-based simulation and digital twins.
