Can drones, the small unmanned aircraft that are at the forefront of fields from warfare to commercial delivery systems, fly without human intervention? A team of Hungarian researchers answers yes, having created 10 drones that self-organize as they move through the air.
The team based its creation on birds such as pigeons, which fly in tight bunches while making adjustments and decisions. They fitted quadcopters — drones with four rotors — with GPS, processors and radios that allow them to navigate in formation or while following a leader.
Like “gregarious animals” such as birds and fish, the flock of drones follows rules of collective motion, says Tamas Vicsek, a physicist who teaches at Budapest’s Eötvös Loránd University. “We came to the conclusion that one of the best ways to understand how animals move together is to build robots — flying robots.”
And like those animals, the drone flock was tested as it flew around in open fields, not in a controlled indoor test environment, as Nature’s Ed Yong reports.
The drones can negotiate tricky paths, such as when their route becomes tightly confined. When that happens, some of them hover in place to wait their turn. And it’s all done without a central computer or controlling device, the researchers say. Instead, they use “flocking algorithms,” says Gabor Vasarhelyi, who led the robotics phase of the project.
“Drones are most commonly associated with war, terrorism, and cyberattacks, but drones can be used in more peaceful civil applications as well,” Vasarhelyi says. “With a flock of drones, you can create a self-organized monitoring system from the air, or you can even deliver food or mail.”
Here in the U.S., drones are expected to someday buzz around carrying out commercial tasks — but not before the Federal Aviation Administration issues new regulations governing such activity. As we’ve reported before, Amazon is developing a drone delivery system.
The flock of drones also reminded us of an amazing set of videos that were highlighted on PetaPixel last month, in which Rhode Island School of Design artist Dennis Hlynsky illustrated the flight paths of dozens of birds in urban settings.
Hlynsky used a video-editing technique that’s similar to one increasingly used in sports TV to make the flying birds’ images linger and create streaming patterns.
In the marine environment of Arctic Alaska, the seasonal presence (or absence) of sea ice influences everything: weather systems, food webs, migration patterns, human cultures, and resource development. Join scientists from NOAA, UAF, and the U.S. Fish And Wildlife Service as they share findings and thoughts on 2 years of unprecedented research in the Northern Bering and Chukchi Seas.
This program will be produced and recorded for broadcast on 360 North Television in collaboration with the Arctic Eis Project, and with funding support from the Alaska Community Coastal Impact Assistance Program through the Alaska Department of Natural Resources and the U.S. Fish & Wildlife Service.
Amanda Filori will be exhibiting her current works “Blues Obsession” at KTOO beginning on June 3rd, 2016 and displaying until the end of the month. Reception is from 4:30pm to 6:30pm upstairs at KTOO. For more information: www.facebook.com/amandafiloriartist
