The Zombie Rises Again: Drone Registration Is Back

December 14, 2017 by 69 Comments

It’s a trope of horror movies that demonic foes always return. No sooner has the bad guy been dissolved in a withering hail of holy water in the denoeument of the first movie, than some foolish child in a white dress at the start of the next is queuing up to re-animate it with a careless drop of blood or something. If parents in later installments of popular movie franchises would only keep an eye on their darn kids, it would save everybody a whole lot of time!

The relevant passage can be found in section 1092(d) of the National Defense Authorization Act, on page 329 of the mammoth PDF containing the full text, and reads as follows:

(d) RESTORATION OF RULES FOR REGISTRATION AND MARKING OF UNMANNED AIRCRAFT
.—The rules adopted by the Administrator
of the Federal Aviation Administration in the matter of registration
and marking requirements for small unmanned aircraft (FAA-2015-
7396; published on December 16, 2015) that were vacated by the
United States Court of Appeals for the District of Columbia Circuit
in Taylor v. Huerta (No. 15-1495; decided on May 19, 2017) shall
be restored to effect on the date of enactment of this Act.

This appears to reverse the earlier decision of the court, but does not specify whether there has been any modification to the requirements to prevent their being struck down once more by the same angle of attack. In particular, it doesn’t change any of the language in the FAA Modernization Act of 2012, which specifically prevents the Agency from regulating hobby model aircraft, and was the basis of Taylor v. Huerta. Maybe they are just hoping that hobby flyers get fatigued?

We took a look at the registration system before it was struck down, and found its rules to be unusually simple to understand when compared to other aviation rulings, even if it seemed to have little basis in empirical evidence. It bears a resemblance to similar measures in other parts of the world, with its 250 g weight limit for unregistered machines. It will be interesting both from a legal standpoint to see whether any fresh challenges to this zombie law emerge in the courts, and from a technical standpoint to see what advances emerge from Shenzhen as the manufacturers pour all their expertise into a 250 g class of aircraft.

Building A Drone That (Almost) Follows You Home

December 13, 2017 by 9 Comments

There’s a great deal of research happening around the topic of autonomous vehicles of all creeds and colours. [Ryan] decided this was an interesting field, and took on an autonomous drone as his final project at Cornell University.

The main idea was to create a drone that could autonomously follow a target which provided GPS data for the drone to follow. [Ryan] planned to implement this by having a smartphone provide GPS coordinates to the drone over WiFi, allowing the drone to track the user.

As this was  a university project, he had to take a very carefully considered approach to the build. Given likely constraints on both money and time, he identified that the crux of the project was to develop the autonomous part of the drone, not the drone itself. Thus, off-the-shelf parts were selected to swiftly put together a drone platform that would serve as a test bed for his autonomous brain.

The write up is in-depth and shares all the gritty details of getting the various subsystems of the drone talking together. He also shares issues that were faced with altitude control – without any sensors to determine altitude, it wasn’t possible to keep the drone at a level height. This unfortunately complicated things and meant that he didn’t get to complete the drone’s following algorithm. Such roadblocks are highly common in time-limited university projects, though their educational value cannot be overstated. Overall, while the project may not have met its final goals, it was obviously an excellent learning experience, and one which has taught him plenty about working with drones and the related electronics.

The British Drone Law Reaches Parliament

December 5, 2017 by 52 Comments

We’ve brought you a variety of stories over the years covering the interface between multirotor fliers and the law, and looked at the credibility gap between some official incident reports and the capabilities of real drones. In the news this week is a proposed new law in front of the British House of Commons that would bring in a licensing scheme for machines weighing over 250 g, as well as new powers to seize drones. We’ve previously told you about the consultation that led up to it, and its original announcement.

As a British voter with some interest in the matter, I decided to write to my Member of Parliament about it, and since my letter says what I would have written to cover the story anyway it stands below in lieu of the normal Hackaday article format. If you are a British multirotor flier this is an issue you need to be aware of, and if you have any concerns you should consider raising them with your MP as well.

Flame Throwing Drone Is Actually Useful

December 3, 2017 by 40 Comments

A team in Xiangyang, China is using a flame-throwing drone to clear debris from high voltage power lines. These lines are made of metal of course, and are impervious to the high heat of the flames. Any type debris that gets on the lines will be charred to a cinder in just a few seconds. This is all is quite a bit safer than sending a human with some type stick up there near the high voltage lines.

Over the years here at Hackaday, we’ve seen people attach some strange things to drones. We can all recall the drone with a real firing pistol. And how about that drone with the huge flamethrower trying to cook a turkey. And let’s not forget the drone that fires bottle rockets.  [Caleb Kraft] did a write-up about hacking the AR drone years ago and mentioned that someone put an Estes-rocket on a drone.  While all of these are incredibly dangerous, ill-advised and for the most part useless, this new power line clearing drone may be the first exception we’ve seen.

What’s the strangest thing you’ve seen someone put on a drone?

High-Speed Drones Use AI To Spoil The Fun

November 29, 2017 by 17 Comments

Some people look forward to the day when robots have taken over all our jobs and given us an economy where we can while our days away on leisure activities. But if your idea of play is drone racing, you may be out of luck if this AI pilot for high-speed racing drones has anything to say about it.

NASA’s Jet Propulsion Lab has been working for the past two years to develop the algorithms needed to let high-performance UAVs navigate typical drone racing obstacles, and from the look of the tests in the video below, they’ve made a lot of progress. The system is vision based, with the AI drones equipped with wide-field cameras looking both forward and down. The indoor test course has seemingly random floor tiles scattered around, which we guess provide some kind of waypoints for the drones. A previous video details a little about the architecture, and it seems the drones are doing the computer vision on-board, which we find pretty impressive.

Despite the program being bankrolled by Google, we’re sure no evil will come of this, and that we’ll be in no danger of being chased down by swarms of high-speed flying killbots anytime soon. For now we can take solace in the fact that JPL’s algorithms still can’t beat an elite human pilot like [Ken Loo], who bested the bots overall. But alarmingly, the human did no better than the bots on his first lap, which suggests that once the AI gets a little creativity and intuition like that needed to best a Go champion, [Ken] might need to find another line of work.

Russian Drone Can Lift 142 Phantom 3 Drones

November 28, 2017 by 58 Comments

Russia has long been known for making large machines. They hold the current record for the largest helicopter ever made – the MiL V12. Same goes for the world’s largest airplane, the Antonov An-225. Largest submarine? Yep, they made that too – the Typhoon class. It would appear they’ve thrown their hat in the drone business as well.

While the SKYF drone is made by a private Russian company, it is one of the largest drones we’ve ever seen. Able to lift 400 pounds (a Phantom 3 weighs 2.8 pounds) and can fly for eight hours, the SKYF drone is a nice piece of aeronautical engineering. Quad-copter style drones provide lift by brute force, and are typically plagued with low lift capacities and short flight times. The SKYF triumphs over these limitations by using gasoline powered engines for lift and electric motors for navigation.

It’s still in the prototype stage and being advertised for use in natural disasters and the agriculture industry. Check out the video in the link above to see the SKYF in action.

What’s the largest drone you’ve seen?

Can Commodity RC Controllers Stay Relevant?

November 20, 2017 by 42 Comments

Visualize some radio controlled airplane fanatic of yesteryear, with the requisite giant controller hanging from a strap, neck craned to see the buzzing dot silhouetted against the sky. It’s kind of a stereotype, isn’t it? Those big transmitters were heavy, expensive, and hard to modify, but that was just part of the challenge. Additionally, the form factor has to a degree remained rigid: the box with gimbals — or for the 3-channel controller, the pistol-grip with the big pot that looks like a cheesy race car wheel.

With so much changing in RC capabilities, and the rise of custom electronics across so many different applications, can commodity RC controllers stay relevant? We’re facing an age where the people who invest most heavily in RC equipment are also the ones most likely to want, and know how to work with customization for their rapidly evolving gear. It only makes sense that someone will rise up to satisfy that need.
