## Summary

Shanghai Jiao Tong University professor Weinan Zhang presented a seven-layer physical AI technology stack at CNCC 2026, spanning hardware and systems, data and simulation, perception, world models, foundation models, physical agents and industry applications. He says the hardest part is connecting layers so that perception, decision-making, execution and feedback form a reliable whole.
