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)
Ann, this is a remarkable integration of a number of technologies -- solar, battery, energy storage, conversion of ocean movement. If you gather a number of technologies together no sngle technology has to be perfect. This is a good example.
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?
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.
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.
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.
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 .
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.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
