Researchers have designed micro-unmanned aerial vehicle inspired by a maple seed. The University of Maryland engineers studied the spiral flight the seeds take when they fall from a tree and created what the university claims is the "world's smallest controllable single-winged rotocraft."
In the 1950s, researchers first tried to create an unmanned aerial vehicle that could mimic a maple seed's spiraling fall. Ever since, their attempts have been foiled by instability, resulting in a lack of control over the tiny (less than one meter) vehicles, which were easily knocked off course by wind.
"Spiraling Flight of Maple Tree Seeds Inspires New Surveillance Technology"
The Clark School (Aerospace Engineering) students have solved the steering problem and provided a solution that allows the device to take off from the ground and hover, as well as perform controlled flight after its initial fall to the ground after being deployed from an aircraft. The device can also begin to hover during its initial descent, or after being launched by hand.

Media artist Michael Naimark writes: In 1990, right as the first VR wave was swelling, Stewart Brand and Grateful Dead manager Jon Mcintyre concocted a scheme to produce an invitation-only 24-hour VR event modeled after the Electric Cool-Aid Acid test. They convinced Colossal Pictures, the largest soundstage in San Francisco, to host it. Dozens of […]
In Wired, BB pal Kevin Kelly wrote a definitive feature about the current (and future?) state of virtual reality, technology that many of us first tried in the late 1980s but took nearly thirty years to be ready for prime time. I first put my head into virtual reality in 1989. Before even the web […]
You never know when new projects, ideas or opportunities can drop into your lap at a moment’s notice. That may require you to learn a new programming language like Python. Or maybe you need a primer on 3D game development. Or you might realize you could use a serious brush-up on iOS mobile creation.Point is, […]
Isn’t it about time to stretch what your Mac can do? I mean, you’ve got plenty of great programs now…but don’t you think you could use some new tools to get your creative, analytical and organizational juices really flowing? It’s spring, so we cleaned up a whole bunch of super-cool apps lying around and packaged […]
In the world of app development, there’s no greater arena to find success than with Android users. About 80% of the smartphones in use today worldwide operate on the Android operating system, so if you build a great app that Android users love, you’re an international rock star. You’ll be able to make sure your […]
