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.
A group of tech firms will meet today to plan the filing of an amicus brief in support of lawsuit to challenge U.S. President Donald Trump’s “Muslim Ban.” Trump’s order was issued on Friday, and restricts immigration from seven Muslim-majority countries in which Trump has no business interests. Adjacent Muslim-majority nations in which Trump does […]
The World Economic Forum asked “leaders from business, government, academia and nongovernmental and international organizations” to take a survey on the potential risks and benefits of different emerging technologies. They seemed to think the space technologies will have little benefit and pose little risk. Energy capture, storage, and transmission has the great promise and little […]
The graphene temporary tattoo seen here is the thinnest epidermal electronic device ever and according to the University of Texas at Austin researchers who developed it, the device can take some medical measurements as accurately as bulky wearable sensors like EKG monitors. From IEEE Spectrum: Graphene’s conformity to the skin might be what enables the […]
