07-09-2010 08:48 BJT

A group of Japanese researchers has developed robots that can navigate the ocean's depths to hunt for seabed mineral reserves. The team has built two types of autonomous models.

One submarine-shaped robot looks for mineral reserves by examining the seabed using sound waves. The other takes photos of the same spot from two meters above. The researchers say the robots can work at depths of up to 15-hundred meters. They plan to explore an area of the Sea of Japan starting next month.
