Drones Rain Down Rat Poison On The Galapagos

February 16, 2019 by Brian McEvoy 19 Comments

If your favorite movie is Ratatouille, now would be a good time to read a different article. Rats on the Galápagos Islands are an invasive species and eradication is underway. This is not a first for the islands, and they are fiercely protected since they are the exclusive home to some species including the distinctive tortoise from which the island derives its name and of course finches. Charles Darwin studied the finches while writing On the Origin of Species. So yeah, we want to keep this island from becoming unbalanced and not disturb the native wildlife while doing it. How do we check all these boxes? Technology! Specifically, hexacopters carrying rat poison.

The plan is simple, drive a truck to a central location, release the ~~hounds~~ drones and fifteen minutes later they come back after flying high above the indigenous wildlife and dropping pest control pellets. The drones save time and labor, making them a workhorse rather than a novelty. This work experience on their resume (CV) could open the door to more dirty work or more wholesome activities. Who is to say that the same drones, the exact same ones, couldn’t deliver plant seeds, or nourishing food to the dwindling species harmed by the rat population explosion.

What would you deliver with drones? How about providing parcels or just learning a better way to navigate?

Automate The Freight: Amazon Tackles The Last Mile Problem On Wheels

February 11, 2019 by Dan Maloney 85 Comments

We’ve been occasionally exploring examples of what could be the killer application for self-driving vehicles: autonomous freight deliveries, both long-haul and local, as well as some special use cases. Some, like UAV delivery of blood and medical supplies in Kenya, have taken off and are becoming both profitable and potentially life-saving. Others, like driverless long-haul trucking, made an initial splash but appear to have gone quiet since then. This is to be expected, as the marketplace picks winners and losers in a neverending quest to maximize return on investment. But the whole field seems to have gotten a bit sleepy lately, with no big news of note for quite a while.

That changed last week with Amazon’s announcement of Scout, their autonomous delivery vehicle. Announced first on Amazon’s blog and later picked up by the popular and tech press who repeated the Amazon material almost verbatim, Scout appears at first glance to be a serious attempt by Amazon to own the “last mile” of delivery – the local routes that are currently plied by the likes of UPS, FedEx, and various postal services. Or is it?

Make Your Lego Fly

February 10, 2019 by Richard Baguley 8 Comments

We probably all used to make our Lego fly by throwing it across the room, but Flite Test have come up with a slightly more elegant solution: they converted a Lego quadcopter to fly. They did it by adding a miniature flight controller, battery and motors/rotors to replace the Lego ones in the Lego City Arctic Air Transport kit. This combination flies surprisingly well, thanks to a thoughtful design that balances the heavier components inside the case.

Drone Gives Up Its Wireless Secrets To Zigbee Sniffer

February 8, 2019 by Dan Maloney 2 Comments

There’s something thrilling about decoding an unknown communications protocol. You start with a few clues, poke at the problem with some simple tools, and eventually work your way up to that first breakthrough that lets you crack the code. It can be frustrating, but when you eventually win, it can be very rewarding.

It seems that [Jason] learned this while decoding the wireless conversation between his mass-market quad and its controller. The quad in question, a Yuneec Q500, is one of those mid-range, ready-to-fly drones that’s targeted at those looking to get in the air easily and take some cool pictures. Unsure how the drone and controller were talking, [Jason] popped the covers and found a Zigbee chipset within. With the help of a $14 Zigbee USB dongle and some packet sniffing software from TI, [Jason] was able to see packets flowing, but decoding them was laborious. Luckily, the sniffer app can be set up to stream packets to another device, so [Jason] wrote a program to receive and display packets. He used that to completely characterize each controller input and the data coming back from the drone. It’s a long and strange toolchain, but the upshot is that he’s now able to create KML in real time and track the drone on Google Earth as it flies. The video below shows the build and a few backyard test flights.

Congratulations to [Jason] for breaking the protocol and opening up drones like this for other hackers. If you’re interested in learning more about Zigbee sniffing, you can actually hack a few smarthome gadgets into useful sniffers.

Can You Take Control Of A TinyWhoop?

February 7, 2019 by Jenny List 16 Comments

Regular readers will have followed our series of posts looking at the issues surrounding reports of drones in proximity to aircraft, and will have noted that we recently asked our community how they would approach the detection and handling of marauding drones in controlled airspace. We are mere amateurs though by comparison to a team with its roots in Delft University of Technology’s Micro Air Vehicle Laboratory, because they have approached the problem through DroneClash, a spectacle best described as akin to a Robot Wars competition for drones. Their website states that “Anything goes, with one exception: no jamming“, and teams will do battle before an audience for a share in a considerable prize fund.

The fun is not however limited to team members. People in the audience will also be able to participate, by being invited to try their luck at bringing down a TinyWhoop that will periodically fly into the arena for a chance at their own prize. The ubiquitous cheap toy drone will be accessible through software, and would-be attackers are invited to register in advance to take a pop at it.

It looks as if DroneClash will be an unmissable event for anyone able to make it to the Netherlands on March 16th. We’ve mentioned it in past years, and we look forward to seeing what comes out of it this year too.

FAA Proposes Refined Drone Regulations

February 4, 2019 by Tom Nardi 77 Comments

The wheels of government move slowly, far slower than the pace at which modern technology is evolving. So it’s not uncommon for laws and regulations to significantly lag behind the technology they’re aimed at reigning in. This can lead to something of a “Wild West” situation, which could either be seen as a good or bad thing depending on what side of the fence you’re on.

In the United States, it’s fair to say that we’ve officially moved past the “Wild West” stage when it comes to drone regulations. Which is not to say that remotely controlled (RC) aircraft were unregulated previously, but that the rules which governed them simply couldn’t keep up with the rapid evolution of the technology we’ve seen over the last few years. The previous FAA regulations for remotely operated aircraft were written in an era where RC flights were lower and slower, and long before remote video technology moved the operator out of the line of sight of their craft.

To address the spike in not only the capability of RC aircraft but their popularity, the Federal Aviation Administration was finally given the authority to oversee what are officially known as Unmanned Aerial Systems (UAS) with the repeal of Section 336 in the FAA Reauthorization Act of 2018. Section 336, known as the “Special Rule for Model Aircraft” was previously put in place to ensure the FAA’s authority was limited to “real” aircraft, and that small hobby RC aircraft would not be subject to the same scrutiny as their full-size counterparts. With Section 336 gone, one could interpret the new FAA directives as holding manned and unmanned aircraft and their operators to the same standards; an unreasonable position that many in the hobby strongly rejected.

At the time, the FAA argued that the repealing Section 336 would allow them to create new UAS regulations from a position of strength. In other words, start with harsh limits and regulations, and begin to whittle them down until a balance is found that everyone is happy with. U.S. Secretary of Transportation Elaine L. Chao has revealed the first of these refined rules are being worked on, and while they aren’t yet official, it seems like the FAA is keeping to their word of trying to find a reasonable middle ground for hobby fliers.
