Artist Explores the Sea Without Leaving Her Wheelchair

Physically-challenged people don’t need to miss out on all of life’s activities. With a little out-of-the-box thinking and ingenuity, anything is possible. Take Sue Austin for instance. She’s an artist in the UK and she is able to see the wonders of the ocean without ever leaving her wheelchair.

Austin has been wheelchair-bound since 1996 and obviously she has not let it stop her one bit. The underwater wheelchair work has been dubbed “Finding Freedom,” and is part of a larger project that she is working on. The wheelchair uses a propeller and fins positioned at the back of her legs that allow her to steer using an acrylic strip attached to her feet.

The design was challenging at first, since most propeller models use hand movements and she lacks the strength to use them. The answer was to make her wheelchair more buoyant by modifying the heel plates into fins and tweaking the seat. The video is pretty amazing and she is a true inspiration.

University of Victoria’s Mano underwater robot to prowl Arctic waters for legendary ships

University of Victoria's Mano underwater robot to prowl Arctic waters for legendary ships

Canadians well-versed in their history are very aware of Sir John Franklin‘s ill-fated 1845 expedition to find the Northwest Passage: a British voyage that set out to establish a sailing route through the Arctic and ended with the untimely, mysterious deaths of its two ship crews. No human ever found the abandoned ships, which makes it all the more fitting that the next best shot at discovery might come through a just-launched autonomous underwater vehicle from the University of Victoria and Bluefin Robotics. Meet the Mano, a new sonar-toting robot that can produce detailed undersea maps all by its lonesome while keeping a steady altitude above the ocean floor. It can only operate for 12 hours at a time, which will keep humans in the area, but its ability to run untethered below storms and cold Arctic winds should dramatically expand the territory that researchers can cover during their share of a larger five- to six-week journey. There’s no guarantee that the Mano will hit the jackpot, or find something recognizable even if it does. Still, any mapping should improve navigation for modern boats — and hopefully prevent others from sharing Sir Franklin’s fate.

LEGO Underwater Robot: Insert Brick and Sink Joke Here

I was very impressed by the LEGO Omniboat, but apparently you can take LEGO vehicles even deeper. An engineering student made this remote controlled underwater robot for a school project. I expect bricks to sink, but I was surprised to see batteries and circuits fare well underwater.

The robot was made by YouTuber roboticsqut, who says that while the vehicle isn’t necessarily waterproof, most of its parts will do fine underwater, including the lead-acid batteries and the motors. Roboticsqut used a pair of XBee PRO adapters to send commands to the robot, which is controlled via an Xbox 360 controller that’s connected to a laptop.

Robotsqut should make more and equip them weapons and minifig crew.

The Extreme Difficulty of Leaving an Underwater Base [Video]

It was just another day for the Aquanauts exploring the warm, crystal waters of Conch Reef when a storm hit. The divers registered the 10-degree temperature drop on their skin a moment after the visibility went from 60 feet down to a dozen. More »

Not quite ready to leave wandering the briny depths up to robots, but still crave some undersea tech? The freshly released iGills Smart Diving System can help. With a polycarbonate housing and free companion app, the setup turns your iPhone into a fully featured recreational dive computer and logbook that can plunge up to 130 feet into the drink. Once connected to the waterproof case’s 30-pin dock, handsets gain access to depth and temperature sensors in addition to six buttons for in-app navigation. Not only does the software provide vital dive information, it also allows users to take stills and videos of their underwater excursions through a glass camera port. If you’re pining for an iOS-assisted diving experience, the iPhone 3GS, 4 and 4S-compatible rig will set you back $330. Check out a quick clip of the accessory, complete with requisite rock music, after the break.

How NASA Uses the Ocean to Train Astronauts for its Most Dangerous Missions [Video]

The astronauts are wearing white suits with American flags and mission patches on them. They’re aware but unworried about the hostile environment inches away from their noses. They’d be dead in seconds if it were not for their air supply. As they bound nimbly along in a state of near-weightlessness, all each astronaut can hear is breathing. More »

There Is No Such Thing as Normal When You Live at the Bottom of the Sea [Mission Aquarius]

The Aquanauts had killed the power and strapped on their emergency air masks. Someone smelled burning. In a rich-oxygen environment like Aquarius, fires can spread with ferocity; any hint of combustion is taken with utter seriousness. The air wasn’t circulating as it was supposed to, and, up above, the life support buoy sounded like it was going to explode. Instead of a steady, even hum, the generator sounded like something between a between a bark and like it was gagging. More »

The Watch Desk Is Always Watching [Video]

Once, in the middle of a storm, while everyone was asleep in the undersea base, the fuel that’s stored in the life support buoy sloshed around enough to stop one of the two generators. The generators power the air supply compressor that keeps everyone in the Aquarius undersea base alive. So what do the Aquanauts have to do if the air quality is at risk? Nothing. The Watch Desk is always watching. More »
