The Jet Bike has a water bottle holder

Relaxation and vigorous exercise rarely coexist, but the FitWet Jet Bike brings them together – sort of. The contraption is a unique piece of exercise equipment that combines a stationary (underwater) bike with a personal jetted tub. Exercise just got a little more attractive.  Read More

A conceptual rendering of the completed naro - tartaruga robot

Well, we shouldn’t be surprised. Scientists have created swimming robotic versions of the cow-nosed ray, the jellyfish, the sunfish, the tuna, and just the generic “fish,” so why not the sea turtle? That’s what a group of scientists from the ETH Zurich research group are in the process of doing, and they’ve named it naro - tartaruga (the original naro was another robotic tuna). As it turns out, a couple of the sea turtle’s natural features make for a pretty good robot.  Read More

The Shoal Consortium's robo-fish could provide round the clock protection against harmful ...

A five foot long (1.5 meter) robo-fish prototype that monitors oxygen levels and salinity is currently being tested in waters north of Spain as part of the EU-funded Shoal Consortium project. If the project proves successful, teams of autonomous robot fish could be patrolling ports, harbors, and estuaries for telltale signs of pollutants in the next few years.  Read More

Scientists believe the tuna fish has a natural body framework that's tailor-made for UUV-l...

Scientists involved in robotics research are increasingly looking toward biological systems for solutions to specific challenges, and when one considers that nature has been solving problems for rather a lot longer than we humans have, this makes sense. Such is the reasoning behind BIOSwimmer: an underwater surveillance robot created by the U.S. Department of Homeland Security's (DHS) Science and Technology Directorate (S and T) that takes its design cues from the tuna fish.  Read More

PLUTO off the coast of San Diego (Image: Paul Wedig, DHS S&T)

When someone mentions drug running, most people probably picture a person coming through an airport carrying a suitcase with a false bottom or with balloons stuffed up their nether regions. We don’t usually imagine things like submarines. Unfortunately, the South American drug cartels not only imagine them, but they build and operate them. To help combat these underwater smugglers, the Department of Homeland Security Science and Technology Directorate (S and T) is operating their own drug-running submarine called PLUTO to develop and test a new generation of detection equipment.  Read More

Scientists are designing autonomous 'coralbots,' that would work together to rebuild damag...

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

Scientists have created a solar-powered swimming underwater robot, inspired by the ocean s...

Previously, we’ve seen swimming robots inspired by the cow-nosed ray, the black ghost knife fish, and the jellyfish – to name just a few. Now, the engineers at AeroVironment have taken it upon themselves to replicate the mola (also known as the ocean sunfish), and the result is an ocean-going robot that gathers its own solar power.  Read More

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

Hilary Bart-Smith's robotic cow-nosed ray

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.  Read More

The SE-35 is waterproof to a depth of 130 feet (40 meters)

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.  Read More
