Liquid Robotics' new Wave Glider robot, the SV3 (right, in red) is bigger than its predecessor, SV2 (left, in yellow), shown during sea trials in Hawaii. The SV3 uses stored solar energy for part of its propulsion system, combined with the Wave Glider's unique, wave-powered energy harvesting system. (Source: Liquid Robotics)
Agreed, Rob. The interesting twist here is that the two sources -- solar and waves -- would seem to be complementary. Typically, the sea is at it's calmest under a clear sky and the waves are highest under overcast skies. If that's the case, one source provides power while the other is idle.
Ahan Ann , Thats really very great uptill now i have only heard about unmanned ground vehicle but this is the very first time i came to know about unmanned marine vehicle with soo many add on features included into it. These sort of marine robots are really very usefull as they help us to gather all the marine information in any type of climate cost effectively . With these sort of unmanned marine vehicles we can keep ourselves aware from earth quakes, tsunamis, and ocean storms etc without engaging any human life in it .
I would imagine the integration of emerging technology will become more common. There are so many new sustainable technologies that are getting proved, it's only natural that end products will begin to show up with a convergence of new technologies.
Rob, thanks for that observation--I agree about the integration of technologies. That, plus using solar for propulsion, is why I wanted to share this with our readers. It's also why the robot won the Edison Award even before this latest innovation.
Elizabeth, the Wave Glider you and I have both written about before did have solar, but it was not used for propulsion--instead, it powered the instruments in the payload, as the article states, and as is still the case. Now, some of that solar energy is also stored and used for propulsion.
It's nice to see the evolution of this useful and innovative robot as it uses alternative energy sources, Ann. I wrote about this technology awhile back and thought it always had a solar component, though? Is this just an extension of that? Or was I misled or mistaken?
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
Researchers at MIT's d'Arbeloff Laboratory are developing shoulder- and hip-mounted robotic arms to help workers in aircraft manufacturing perform difficult or complex assembly tasks that would normally require two people.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
