This is an era where AI sees and hears with sensors, makes decisions at the edge, and moves with actuators.
It provides a balanced overview of physical AI's core technologies and industrial cases, as well as privacy, liability, and job transition issues, and proposes safe adoption principles and a governance roadmap.

Physical AI brings the intelligence of digital artificial intelligence to the real world.
This means that artificial intelligence goes beyond just thinking, but also acts, moves, and creates physical changes.
It's as if intelligent robots and self-moving smart cities, which we only saw in movies, are becoming a reality.
While digital AI, such as web search, image recognition, translation, and chatbots, primarily remain in software interactions, physical AI, such as self-driving cars, robot vacuum cleaners, robotic arms in smart factories, automatic temperature control systems in smart buildings, and medical assistant robots, directly intervene in our lives through physical interactions in the real world.

In a physical AI system, intelligence is not concentrated in a single central server, but rather distributed across multiple edge devices and edge servers.
Each device or server processes data appropriate to its role and processing capabilities, and, when necessary, communicates with each other or exchanges information with the cloud, increasing the efficiency of the entire system.

The combination of physical AI and spatial computing in industrial settings dramatically improves work efficiency.
In factories or warehouses, workers can use AR glasses to project work instructions, assembly process simulations, inventory location information, and machine fault diagnosis information directly onto the real space.
Physical AI robots can perform tasks efficiently based on this information, and workers can check the robot's status in real time and issue necessary instructions.

If physical AI applied to core infrastructure, such as power grid management systems or smart city traffic control systems, were hacked, it could lead to large-scale chaos that could paralyze the entire city.
Therefore, physical AI systems must establish a comprehensive security system that encompasses not only software security but also hardware security and the entire operational process.
This can be strengthened through strong encryption technologies, intrusion detection and defense systems, and blockchain-based data integrity verification technologies.
