'Gobble Hawk' Wins NASA High-Altitude UAV Design Competition

NASA is very proud of the Global Hawk UAVs that it uses for environmental monitoring missions like keeping track of hurricanes, among other things. We should know: we visited them last year. But Global Hawks are super expensive (between $130 and $220 million each, depending on whether or not you factor R&D cost into the mix), and while they have relatively long range and endurance, they can only stay up for about a day (28 hours) at a stretch.

So NASA wants more options, and it has turned to students for ideas. In a press release today, they've announced the winners of a competition to design high endurance uncrewed aerial systems for hurricane tracking. Coming out on top: Virginia Tech's "Gobble Hawk." Heh.

SupraPed Robots Will Use Trekking Poles to Hike Across Rough Terrain

Last year at the Stanford-Berkeley Robotics Symposium, we saw some tantalizing slides from Oussama Khatib about a humanoid robot that used trekking poles to balance itself. We were promised more details later, and the Stanford researchers delivered at the IEEE International Conference on Robotics and Automation (ICRA) this year, where they presented the concept of SupraPed robots.

The idea is equipping robots with a pair of special trekking poles packed with sensors that, according to the researchers, "transforms biped humanoids into tripeds or quadrupeds or more generally, SupraPeds." By using these smart poles to steady themselves, the robots would be able to navigate through "cluttered and unstructured environments such as disaster sites."

'MacGyver' Robots Use Their Environment to Solve Problems

MacGyver could make a rocket-powered harpoon gun/zip line out of some moth balls, cleaning fluid, rope, pulley, and an old telescope. Robots can't do that. But hey, neither can you. What you can do is use objects in your environment to help you complete tasks that you wouldn't otherwise be able to do on your own, and robots are learning how to do the same thing.

Yes, this means that soon they will be unstoppable. And there's video to prove it.

Can a 'Dropship Quadcopter' Deploy Rovers on Mars?

The most ludicrous way of getting a robot to the surface of Mars is maybe stuffing it inside a giant inflatable bouncy ball and dropping it from a parachute. And that is only slightly more ludicrous than attaching it to a rocket-powered hovercrane (a rocket-powered hovercrane!!!) and then lowering it to the ground with some sort of ridiculous cable contraption.

NASA has done both of these things. Successfully.

So, the bar is very high for finding ludicrous ways of getting robots to the surface of Mars, and the European Space Agency (ESA) has taken on the challenge with a quadcopter that can safely drop a rover down onto the Martian surface while hovering.

Tiny Walking Robots Powered by Muscle Cells

Most robots are powered by electrical motors that are big, bulky, heavy, and if they break, you have to replace them. Animals, on the other hand, use a biological motor—a muscle—that also requires electricity, but is far more efficient and, given a chance, can repair itself. We're just starting to be able to manipulate biological structures like these in clever enough ways to let us harness their awesomeness, and engineers at the University of Illinois at Urbana-Champaign have worked them into a tiny little "bio-bot" that uses muscle cells to walk.

North Carolina Set to Outlaw Hunting and Fishing Drones

Restrictions on small drones, model aircraft, sUAS (small unmanned aircraft systems), or whatever you want to call them are being promulgated almost too quickly to chart these days. Late last month the U.S. Federal Aviation Administration forbade modelers from engaging in first-person view piloting, and the National Park Service announced its intention of banning essentially all model aircraft from its 84 million acres—to name just a couple of prominent federal clamp-downs. In addition, 36 states have been busy formulating their own drone regulations this year, four of which have recently enacted laws, mostly focused on protecting people’s privacy. But get ready for a novel variation on this theme working its way through the North Carolina State Assembly.

Please Tell This Robot What a Turtle Looks Like

Pretend you're a robot. (I do this all the time, it's great!). Okay, are you pretending? Awesome! Now, take these colored blocks and BUILD ME A TURTLE, ROBOT!

If you're panicking right now, that's understandable. A general purpose robot would probably have no idea what a turtle was, much less how to build one out of blocks. There are ways that you could teach the robot about turtles and blocks, but you, being a human, are hopelessly flawed and would only be able to teach it your conception of what a turtle should look like and how to use blocks to make one. What the robot really needs is to be able to examine a bunch of different examples of a bunch of different turtles, and then use machine learning to choose the best, most reliable, and most efficient one to build. And rather than have you try and do that all on your own, researchers at the University of Washington are paying strangers to do it as part of a crowdsourced effort.

Video Monday: Curiosity's First Martian Year, Android Newscasters, and Baxter Gets a Promotion

By the time we put together our post on the DARPA Robotics Finals, we were too late to put Video Friday in time for, you know, Friday. And we feel bad about that, we really do. But not we feel especially bad now, because Automaton reader Mike wrote in to let us know how sad he was that we missed (another) Video Friday.

We can't turn back the clock, but we're going to do what we can to make up for it: Mike, this Video Monday is for you.

DARPA Robotics Challenge Finals: Dates, Location, and Everything Else You Need to Know

Yesterday afternoon, DARPA held a briefing to discuss the forthcoming DARPA Robotics Challenge Finals. It's been about six months since the DRC Trials were held in Miami, so we've been expecting an update, and DARPA certainly delivered.

Program manager Gill Pratt spent over an hour explaining what we have to look forward to in Southern California (yes, the Finals will be held in California!) next June (yes, the Finals are not happening this year, as DARPA decided to give teams some extra time) and we've got all the highlights for you.
