Massive manta rays and other pelagic ray species tend to hover near the ocean surface using a flapping motion. Benthic rays, ...

Using robotic fins, researchers at the University of California, Riverside, have learned how stingrays ...

Finding and disposing of mines lurking on the sea floor is dangerous and difficult work. The US Navy wants robotic crawlers capable of descending to nearly 2,000 feet underwater to do this. The ...

Underwater autonomous vessels and robots could play a substantial role in defense operations, but submersibles have historically had trouble communicating across large distances unless they rose to ...

Kraken Robotics Inc. is well-positioned for growth, driven by surging orders for its Synthetic Aperture Sonar (SAS) and subsea batteries. KRKNF benefits from heightened global demand for underwater ...

The latest triumph in ocean technology comes from a small, rugged machine that slipped beneath Antarctic ice into a part of the planet no human has ever seen, gathered a torrent of data, and then did ...

The observation pyramid involves using various robotic platforms to survey ocean areas. Autonomous robotic organizations will be able to make observations over large ocean areas at a fraction of the ...

Light-powered artificial muscles for underwater robots with reversible, high-stroke actuation Demonstrating 3 times greater actuation stroke and 2 times higher work capacity than existing ...

A Korean research team has developed a light-powered artificial muscle that operates freely underwater, paving the way for next-generation soft robotics. The research team—Dr. Hyun Kim at the Korea ...
