The uOne underwater robot may soon be taking on risky, labor-intensive tasks currently performed by human scuba divers. It boasts a unique combination of traits from two different types of undersea bots.

An experimental new undersea robot shows great promise for use in the upkeep of offshore renewable energy platforms. Because it has the ability to climb vertical underwater surfaces – and paint them – it's known as the Crawfish.
-
Minesto's fully operational Dragon 12 looks like some sort of futuristic military drone – but it behaves remarkably like a kite underwater. It uses lift generated by tidal flows to fly patterns faster than the currents, harvesting renewable energy.

Canadian firm Deep Trekker is probably best known for its Revolution, a top-of-the-line underwater ROV (remotely operated vehicle). The company is now offering a much smaller, less pricey yet still very capable model, however, called the Photon.

Although most smartphones are now waterproof, you definitely shouldn't take them snorkeling without an underwater housing. The Universal Lite is one such device that fits a wide range of phones, allowing them to serve as underwater cameras.

Space agencies often put space-suited astronauts in swimming pools, so they can learn to perform tasks in an outer-space-like environment. The UHAB is intended to take things further, by simulating the habitats in which astronauts may someday live.
-
While underwater ROVs (remotely operated vehicles) can be quite useful, there are some tasks that require action to be taken both underwater and on the land. That's exactly where the amphibious Onyx Unmanned Ground Vehicle is designed to come in.

Although Saturn's moon Enceladus and Jupiter's moon Europa both have ice-covered surfaces, oceans may exist beneath that ice. The TRIPLE-nanoAUV 2 project is aimed at getting an uncrewed submersible into those oceans, to search for life.
-
A UK team has revealed plans to build an incredibly ambitious underwater habitat named Sentinel. Assuming it goes ahead, it could revolutionize deep sea research by allowing scientists to live underwater for extended periods in relative comfort.

Getting glue to stick in dry conditions is relatively easy, but having it maintain a bond underwater is much more difficult. That said, a new bio-based glue not only works underwater, it actually gets stronger when immersed.
-
Six years ago we told you about the Scorkl, a mini compressed air tank that allows users to breathe underwater for up to 10 minutes. For easier refills, the 2.0 version can now be ordered with an electric air compressor and a "battery pack."

The CEO and co-founder of Triton Submarines takes us through some highlight dives from an extraordinary career, from salvaging the "smoking gun" from the Challenger space shuttle, to filming with James Cameron, to the bottom of the Mariana Trench.
