A Treasure-Hunting Ocean Robot

This "robotic mermaid" could be more than just a clever way to retrieve sunken treasure (and disappoint amorous sailors). It hints at how humans and robots may someday work together in all sorts of difficult environments. The submersible humanoid robot, called OceanOne, was developed at Stanford University. It recently retrieved priceless artifacts from King Louis XIV's La Lune, a 350-year-old galleon wrecked off Toulon in southern France in 1664. OceanOne has two arms, a head, and a tail-like appendage fitted with motorized propellers.
