Physical AI Documentation Book

Master the Robotic Nervous System

What is Physical AI?

Physical AI represents the convergence of artificial intelligence with the physical world. It's where robots don't just compute—they perceive, reason, and act in real environments.

Perceive

Sensors capture the physical environment: cameras see, LIDAR measures distance, IMUs track orientation.

Process

AI algorithms interpret sensor data, make decisions, and plan actions using neural networks and ML models.

Act

Actuators and motors execute commands, moving limbs, gripping objects, and navigating spaces.
