This unusually mobile species of sea cucumber has only been captured on film once before, in the Gulf of Mexico. Continue reading Watch This ‘Headless Chicken Monster’ Crawl the Deep Southern Ocean
We love a little outside-the-box thinking around here, and anytime we see robots that don’t use wheels and motors to do the moving, we take notice. So when a project touting robotic fish using soft-actuator fins crossed the tip line, we had to take a look.
It turns out that this robofish comes from the fertile mind of [Carl Bugeja], whose PCB motors and flexible actuators have been covered here before. The basic concept of these fish fins is derived from the latter project, which uses coils printed onto both sides of a flexible Kapton substrate. Positioned near a magnet, …read more

Someday Elon Musk might manage to pack enough of us lowly serfs into one of his super rockets that we can actually afford a ticket to space, but until then our options for experiencing weightlessness are pretty limited. Even if you’ll settle for a ride on one of the so-called “Vomit Comet” reduced-gravity planes, you’ll have to surrender a decent chunk of change, and as the name implies, potentially your lunch as well. Is there no recourse for the hacker that wants to get a taste of the astronaut experience without a NASA-sized budget?
Well, if you’re willing to get …read more

It’s pretty surreal to watch all these fish congregate around the data center like it’s an artificial reef. Continue reading Watch Fish Swim By Petabytes of Data at Microsoft’s Underwater Data Center
[Festo] have come up with yet another amazing robot, a swimming one this time with an elegant propulsion mechanism. They call it the BionicFinWave. Two fins on either side almost a body-length long create a wave which pushes water backward, making the robot move forward. It’s modeled after such fish as the cuttlefish and the Nile perch.
What was their elegant solution for making the find undulate? Nine lever arms are attached to each fin. Those lever arms are controlled by two crankshafts which extend from the front of the body to the rear, one for each side. A servo …read more

Many people overlook the fact that the internet relies on vast networks of cables connecting continents under the sea. Continue reading This Is How the Internet Crosses the Ocean
If you’re like us, a body of water is a source of wonder and awe. The wonder comes from imagining what lies hidden below the surface, and the awe is from the fear of trying to find out and becoming one of those submerged objects on a permanent basis. So if you want to explore the depths in relative comfort and safety, a DIY remotely operated underwater vehicle might be the thing you need to build.
Most ROV builds these days seem to follow more or less similar designs, which is probably because they all share project goals similar to …read more

One way to design an underwater monitoring device is to take inspiration from nature and emulate an underwater creature. [Michael Barton-Sweeney] is making devices in the shape of, and functioning somewhat like, clams for his open source underwater distributed sensor network.
The clams contain the electronics, sensors, and means of descending and ascending within their shells. A bunch of them are dropped overboard on the surface. Their shells open, allowing the gas within to escape and they sink. As they descend they sample the water. When they reach the bottom, gas fills a bladder and they ascend back to the …read more

It’s no shock that electric eels get a bad wrap for being scary creatures. They are slithery fleshy water snakes who can call down lightning. Biologists and engineers at the University of California had something else in mind when they designed their electric eel. Instead of hunting fish, this one swims harmlessly alongside them.
Traditional remotely operated vehicles have relied on hard shells and spinning propellers. To marine life, this is noisy and unnatural. A silent swimmer doesn’t raise any eyebrows, not that fish have eyebrows. The most innovative feature is the artificial muscles, and although the details are scarce, …read more
