Underwater robots being developed to save damaged coral reefs

By - September 4, 2012 1 Picture
Scotland may not be the first place that comes to mind when you think of coral reefs, but the deep waters west of the nation are indeed home to reefs not unlike those found in the tropics. Unfortunately, a commercial fishing technique known as bottom trawling regularly damages that coral, putting the reefs at risk. Now, scientists are working on a possible solution to the problem – swarms of small, autonomous coral-fixing robots. Read More

Optical communications system and autonomous microscope to boost underwater research

By - July 30, 2012 6 Pictures
It would definitely be an understatement to say that underwater research has its technical challenges. Remote-operated vehicles (ROVs) must be tethered to surface support vessels with unwieldy communications cables, deep-sea water samples have to be hauled to the surface for analysis ... or do they? Woods Hole Oceanographic Institution recently announced that it has partnered with two private companies, to market a couple of technologies that address both of those situations. Read More

Robotic ray could end up flapping through an ocean near you

By - July 25, 2012 2 Pictures
Sometime in the future, perhaps sometime soon, the robotic jellyfish, octopi and fish cruising the world’s oceans may have to make way for one other companion – the robotic ray. A team led by University of Virginia engineering professor Hilary Bart-Smith has created such a “creature,” in hopes that its autonomously-operated descendants may someday help us humans explore and study the sea, or possibly perform surveillance for the military.

The iGills SE-35 transforms your iPhone into a dive computer

By - July 21, 2012 6 Pictures
The iGills SE-35 is not just another waterproof case for the iPhone, but instead promises to turn Apple’s mobile device into a fully-featured dive computer. The waterproof scuba diving case protects the iPhone down to depths of 130 feet (40 meters) and allows easy underwater usage via six buttons integrated into the design. Users also retain access to the iPhone's camera for underwater shots and on the software side, the SE-35 is offered with a complementary app which features navigation tools and torch, in addition to an automatic dive log.

New algorithms improve efficiency of underwater mine-sweeping robots

By - July 17, 2012 1 Picture
In addition to human divers equipped with sonar cameras, the U.S. Navy has also trained dolphins and sea lions to search for bombs on and around vessels. All these methods are expensive and can’t always deliver the best performance in all environments. Robots would seem to be the obvious answer and underwater robots have been the focus of much research and development in recent years. Now researchers at MIT have developed new algorithms to vastly improve the navigation and feature-detecting capabilities of these robots. Read More

The world's first underwater nightclub

Of all the places you might meet a significant other, underwater is probably the last place that springs to mind. Hence, I guess, the novelty of an underwater nightclub. Created as a viral campaign for TechnoMarine Underwater watches, the unique nightclub "launch" was filmed at a military training facility with navy divers and the set was built 14 feet (4 m) underwater. The breathing helmets are from the commercially-available Sea Trek system, so perhaps it's not all that implausible after all. Read More
