This scientist can control a swarm of drones with his thoughts

What’s the only thing that could make a regular drone sound boring? A swarm of thought-controlled drones, of course.

As unbelievable as it sounds, this is exactly what researchers at Arizona State University have developed — with technology that allows one person to control multiple robotic drones simply by thinking about different tasks. To do this, the operator wears a skull cap which records electrical brain activity through 128 electrodes, and outputs instructions to a computer, which then relays information to the drones via Bluetooth.

“For the past year, we have been working on building a control interface between a human and a swarm of robots by using the brain recordings of the human-commander,” Panagiotis Artemiadis, director of ASU’s Human-Oriented Robotics and Control Lab, tells Digital Trends. “After analyzing the brain recordings, we found areas of the brain that can be used to control the formation and other collective behaviors of a swarm of drones. We record the electrical activity of those areas using non-invasive methods, and we decode this activity to control variables for the robotic swarm. The human commander can control the motion and formation of the robotic swarm in real-time by only thinking about their desired motion.”

Artemiadis’ lab has previously worked on the neural control of prostheses, and has demonstrated that it is possible to carry out highly dexterous control of a robotic arm using electromyographic signals. However, controlling a swarm of drones is another matter altogether.

“The brain is wired to control artifacts that resemble human limbs,” Artemiadis says. “The complexity of a system that requires the brain to activate areas to control robotic artifacts that do not resemble natural limbs — in our cases a swarm of drones — is significant and so far unexplored. Until a few months ago, nobody knew that specific brain areas can be activated when the human observes collective behaviors of swarms. The fact that the brain can adapt to output control actions for a swarm of multiple robots is fascinating and quite useful for human-robots interaction.”

And it’s pretty freaking cool, to boot!

This startup wants to plant a billion trees with a swarm of seed-bombing drones
Flash Forest

Flash Forest

Every year, way more trees are cut down than are planted. Could drones help offset deforestation? The connection between those two points might sound tenuous, but for the folks at Canadian company Flash Forest, not only does it make total sense; it may be the only way to solve a major ecological problem.

Rescue drone can distinguish between survivors, victims in disaster zones
beneath drone

Plenty of humanitarian and first-responder agencies are interested in drone technology. Capable of being rapidly deployed after a potential disaster, and immune to being negatively impacted by things like damaged roads and bridges, drones can play a vital role in rescue efforts. But while many agencies have focused on applications like delivering medical supplies, a new piece of work from a team of international researchers examines how drones could be used to hunt for survivors in the event of a major catastrophe.

In a world's-first study, researchers from the University of South Australia and Baghdad’s Middle Technical University in Iraq demonstrated a new technique for being able to distinguish survivors from deceased bodies from distances of more than 25 feet. The onboard technology can identify things like small movements to indicate heartbeat and breathing rate. It does not look for skin-color changes or body temperature since these require monitoring from a closer distance. Body temperature is also unreliable in warm environments and when people are wearing insulated clothing.

Any child who can do basic math can hack YouTube Kids’ parent controls
YouTube Kids

YouTube Kids officially launched Friday on the web. The website offers a similar experience to the YouTube Kids mobile app and allows parents to set limits on what content their children are able to watch on the platform.
The idea is that parents decide what children ages 12 and under and able to watch on the service and then those kids will be essentially locked out of viewing inappropriate content.
However, there’s one big issue with that age lock: to verify that you're a parent, all you need to do is answer a basic math question that children using the service could potentially solve, essentially giving them the ability to unlock it and watch whatever they want anyway.
Independent Journal Review editor Josh Billinson highlighted the issue on Twitter. Essentially, when kids try to unlock YouTube Kid they’re faced with a question “For Parents Only” that is consistently an easy multiplication problem. While that might be slightly challenging for younger kids, children who are toward the older part of YouTube Kids’ demographic, from 8 to 12 years old, should probably be able to handle basic multiplication by now.

Another concern: Even if a child doesn’t know multiplication, and ignoring the fact that calculators exist, making an incorrect guess at the questions doesn't ever lock a child out -- it just produces another math question. In theory, this means a kid could keep trying until they got a question they could actually answer. Or, if they kept typing in the same number, there’s a chance that the number they type will eventually be correct and grant them access.
The launch of YouTube Kids on the web comes the same day that Google agreed to pay between $150 and $200 million to resolve an FTC investigation into YouTube over alleged violations of children’s property law, Politico reports.
That issue stemmed from privacy groups claiming that YouTube collected personal information about minors and then used that information to target them with advertising without their parent’s permission.
The settlement is the largest ever made for a violation of the Children’s Online Privacy Protection Act. Previously, the highest settlement ever was $5.7 million, which was paid in February by TikTok competitor Musical.ly.
We've reached out to YouTube to see if it has plans to change the authentication tool and will update this post if and when we hear back.
