The Serpent remotely operated vehicle (ROV) from Seaview Systems is designed for exploring very small-diameter pipelines. It can investigate conduits as small as 9 inches (23 cm) in diameter, and fit around bends with a radius as narrow as 27 inches (68.5 cm). Measuring 9 inch x 9 inch x 57 inch (23 cm x 23 cm x 145 cm) and weighing 70 lb (32 kg), the Serpent runs on two 300W brushless DC motors that give it a total forward thrust of 18 lb (8 kg). With a 0.5 inch (1.3 cm) diameter fiber-optic tether, it can explore as far as 6,000 ft (1,830 m) down a pipe or tunnel. A 360-degree pan/orbit/zoom color camera and two color cameras are included, along with two 70W high-intensity LEDs. The robot also has heading, pitch and roll, and depth sensors, as well as sonar. A fiber-optic telemetry system provides up to three video channels, four RS232 channels, and two RS485 channels. (Source: Seaview Systems)
William, I wasn't sure where your (usually) straightforward statements ended and tongue-in-cheek started, either. Re Google, I know what you mean: it's getting harder and harder to find good basic info instead of commercial/sales info. But that result was predicted when the Internet became commercialized.
Ann, it was not completely clear when things turned, so you did a good one on me. About Google; I have had quite a bit of serious frustration when attempting to find information about some product or system and the dumb google search instead turns up a hundred sites that want to sell me one, even if they don't have it and have no concept of what it is. At that point it becomes a first rate time waster.
But on the other topic, while invisibility in the normal sense is a big challenge, being un-noticed is a lot simpler, hence the comment about the missile launching dolphin and such. Consider how easy it would be for you to pass somebody by if a whole crowd were wearing AnnThryft masks. Spotting the real one is a challenge if they all look similar.
Ann, OK, that makes sense. Of course a missile launching fish would be a very interesting creature. Probably we could train a school of dolphin to escort a missile launching robot dolphin, giving it a nearly perfect cover. The main hazard would be poachers. Perhaps DARPA would be interested in that concept, which just popped into my head. I am not at all familiar with the DARPA dolphin program and have never heard of "Freddy the Fish".
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
