What Is Physical AI?

Physical AI refers to AI that understands the physical world and takes direct action within it. Unlike digital AI that only handles text and images on screens, Physical AI interacts with the real world through robots, autonomous vehicles, drones, and other physical embodiments.

NVIDIA CEO Jensen Huang declared that "the next wave of AI is Physical AI," and has been making massive investments in this field.

Why Physical AI Now?

LLM Success as Foundation

The general reasoning capabilities demonstrated by large language models are now being applied to robotics. Robots can understand natural language commands and respond flexibly to new situations.

Simulation Technology Advances

Physics simulation platforms like NVIDIA Omniverse and Isaac Sim have advanced to the point where robots can be trained at massive scale in virtual environments.

Hardware Performance Gains

Edge AI chips, sensors, and actuators have improved significantly, enabling real-time AI inference directly on robots.

Core Technologies of Physical AI

1. World Models

Models that understand physics laws, spatial relationships, and causality. They learn physical common sense like "if you tilt a cup, water spills."

2. Sim-to-Real Transfer

Technology that applies policies learned in virtual environments to real robots. After millions of trial-and-error iterations in simulation, the learned behaviors are deployed to reality.

3. Multimodal Perception

Integrating data from cameras, LiDAR, tactile sensors, and inertial measurement units to perceive the environment.

4. Motor Control

Precisely controlling joints, wheels, and propellers to perform smooth and safe movements.
