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.
The public bathroom at Beijing’s Temple of Heaven Park now has a toilet paper dispenser outfitted with a camera and facial recognition technology to prevent toilet paper theft. From the New York Times: Before entering restrooms in the park, visitors must now stare into a computer mounted on the wall for three seconds before a […]
Poking a golden tortoise beetle (“goldbug”) triggers the insect’s color to change from gold to a red-orange. Inspired by the natural system underlying that insectoid superpower, MIT researchers have developed flexible sensors circuits that can be 3-D printed. Eventually, the technology could lead to sensor-laden skin for robots. From MIT News: “In nature, networks of […]
MNTNT’s Albert Clock is a clock that presents the hours and minutes as simple math problems. Is it annoying or engaging? Or…. both! In standard mode, the queries change every minute. They are completely random, so even the query for the hours change, even if the result stays the same. You can speed up this […]
What could be more fun than a slingshot that shoots tiny airplanes? A slingshot that shoots tiny glowing airplanes of course! These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
