NASA's Athlete Mars rover does a little dance, gets down tonight (video)
Its been a few years since we last checked in on NASA's All Terrain Hex Limbed Extra Terrestrial Explorer rover -- aka, Athlete. Now a half-scale working prototype standing 15 feet tall, weighing 2.5 tons (about 2,300 kg), and capable of a 1.25 mph (2 kmph) top speed has been set loose for testing by its Jet Propulsion Laboratory creators. Its first task, set to begin next month in Arizona, will be to complete a test circuit of at least 25 miles (about 40 km) in two weeks under its own power. Failing that, we hear Woz is looking for a dance partner. See what we mean in the video of Athlete demonstrating a flare for cargo transport after the break.
NASA's robot submarine achieves perpetual motion, of a sort
The Sounding Oceanographic Lagrangrian Observer Thermal Recharging (SOLO-TREC) autonomous underwater vehicle is, well, quite a mouthful. It's also the first submarine that can run a sizable percentage of forever without requiring a charge. When the 183-pound buoy dives, cooler water temperature causes a liquid wax-like substance inside to solidify, squeezing out oil that drives a hydraulic generator; when it surfaces, the wax softens once again, ready for another round. Every dive produces 1.7 watt-hours of electricity, enough to power all the instruments, GPS and buoyancy-control pump on board. It's like a drinking bird that never runs out of water. Designed by NASA's Jet Propulsion Laboratory and Scripps researchers, the thermal engine is envisioned as an oceanography tool... but since the US Navy also has a finger in the pie, don't be surprised if it plays a minor role in the coming robot apocalypse as well.
Second Life Places: NASA CoLab
We've wanted to visit NASA (National Aeronautics and Space Administration) for years, but haven't previously had the opportunity. Some of us live on the wrong continent to do so, for one thing. We've visited NASA now however, and you can too. NASA has a presence in Second Life. NASA created the CoLab Island to enable 'co-working and project incubation ... for NASA staff and the entrepreneurial technology community'. There's a bunch more marketer-speak on their 'NASA CoLab SL Project Overview' notecard, but the English form of it is that they want to talk to us, and want us all to talk to them. %Gallery-22814%
NASA's six-legged ATHLETE bot will roam the moon
Mars isn't the only heavenly body that NASA is trying to colonize with robots: the US space agency is currently working on a prototype rover named ATHLETE that may be cruising around the moon within the next decade. Short for All Terrain Hex Limbed Extra Terrestrial Explorer, ATHLETE sports six wheeled "legs" attached to a hexagonal frame loaded with cameras and sensors, allowing an Earth-bound operator to get a 360-degree sense of his or her surroundings. While the current iteration is only half as big as the final version will be, this rover will eventually be able to land and carry up to 20 tons of gear -- but without any sort of onboard defense system, it will probably stand little chance against the first Decepticon attack.
