Lockheed Martin develops maple-seed-like drone

The seeds that drop from maple trees each fall, whirring softly to the ground like silent one-winged helicopters, are the inspiration for a new kind of flying machine that could be useful for military information-gathering.
Lockheed Martin's Intelligent Robotics Laboratories, based in Cherry Hill, N.J., has spent the last five years developing an unmanned craft to replicate the motion.
The device, dubbed the Samarai, is scheduled to make its public debut next week at the Association for Unmanned Vehicle Systems International conference in Washington, D.C.
Its engineers gave The Associated Press a preview Wednesday at an indoor soccer field in Southampton, N.J.
The Samarai is about a foot long, and has just two moving parts plus a camera. It can be controlled by a remote control or by an app on a tablet computer.
On Wednesday, engineers Dave Sharp and Craig Stoneking piloted a Samarai, which in flight looked like a translucent blur around a pair of blue and red lights. They moved it from the soccer field to the ceiling some 30 feet above and across the field.
By remote control, the flight was steady. With the easier-to-use app, it twirled around a bit, not unlike a maple seed. That, Stoneking said, will be fixed in the future.
The idea isn't brand new. Students at the University of Maryland built a smaller maple seed-inspired flyer a few years ago.
Bill Borgia, director of the Lockheed Martin lab, said it could be useful for the military and police as well as his lab's work on other devises.
Troops could carry the devices in their backpacks, launch them by throwing them like boomerangs and use real-time images from cameras to find out what might be around the next corner.
They could be dropped from plane to collect ground-level images instead of just the aerial images used now.
Troops or police officers could use them even to get a look inside buildings.
Unlike most drones used by the military, these can hover in place like a helicopter and take off vertically in tight spaces.
Borgia said they could come in a variety of sizes and be produced cheaply by 3D printing, which uses layers of plastic to create objects.
Putting a motor on a piece of plastic that shaped like a maple seed and getting it to fly was relatively easy, Borgia said. Learning to control the natural movements was the challenge.
Borgia said the lessons learned trying to harness and mimic a natural design have already been used in some of his lab's other projects robots that behave like human hands or move about like insects.
Lockheed officials wouldn't say how much it cost to develop or which government agencies helped fund the research.

AS LONG AS religionist cultures which are designed to outreproduce their neighbors continue to exist, then there will ALWAYS be strife and conflict in the world.
There will ALWAYS be families which continue to grow despite their inability to support themselves; and when their children begin to starve their religions will tell them that god is angry because the infidel still exists, and so the infidel will get the food.
Religions teach the faithful to reject the education which would teach them how to live within their means. Religions teach them that god will provide as long as they do exactly as he wishes, which is invariably to supplant the unbeliever.
You want conflict and misery to end, then you must find a way to end ALL religion.

This compares with a world population growth rate of 1.12% per year. As of 2011, it is predicted that the world's Muslim population will grow twice as fast as non-Muslims over the next 20 years; within a generation, Muslims will make up more than a quarter of the global population."

I'm not sure there will be good numbers.
At the risk of invoking Goodwins law:
Ask yourself: how many people would have actively said that the NSDAP is terrible if so asked in 1939-1945? And they only got 44% of the votes in the only democratic election they were in (in 1933).
It's very hard to get representative numbers in repressive regimes. But I think if you ask muslims in the US or Europe about these issues - where they have the freedom to say anything they want - you will hardly get those numbers.

The correct analogy is "how many people would have said that brutally murdering civilians in concentration camps is the right thing to do?" They are not just stepping around the issue in those survey.
Muslims in developed countries may not represent their home population well. They are usually the westernised elite, and in a culture that looks down upon such ideas, too. I dont think the results of the survey can be attributed mainly to oppressive regimes, not that high numbers, spanning so many countries.

That's the real point, isn't it? How well do such surveys represent the population when the environment may induce them to give biased answers? all the countries inthe survey have either repressive regimes or some radical group that actually will kill someone if they speak out too fervently.

You discount how easy it is to manipulate people, including yourself (And otto too!)
For instance your definition of 'repressive' and 'radical' are far from universal. The majority living in those regimes are happy and content with their conditions and cannot imagine being as happy living the way you do, in the midst of godless decadence, moral decay, and self-destruction.
