## Summary

Jazzyear talks with Zhang Dayu, founder and CEO of Weilan Deep Sea, about the path to deploying underwater embodied intelligence. The company chose to start with specific tasks such as structural inspection, cleaning, and patrol inspection, believing that underwater operations account for 20% to 25% of infrastructure value, and that a robot only needs to reliably perform one or two capabilities to change a customer's cost structure.
