London Gatwick Airport Closes Runway In Alleged Drone Strike

July 4, 2017 by 118 Comments

London is one of those cities with an identity problem when it comes to airports. There is no one London airport, instead a group of airports serve the city at various distances from it. London Gatwick is the second largest of these, and sits with its single runway in the Sussex countryside about 30 miles south of the city.

If you follow British news sources, you may have heard a little about Gatwick in the last couple of days. Its runway was closed for two short periods and a selection of flights were diverted, because of what is being reported as a drone sighting. This is an extremely serious matter, responsible multirotor owners will be painfully aware of the distance and altitude regulations surrounding flights near airports.

If you are familiar with the way that drone stories are reported by the mass media, you will probably not need to click on the link above to the BBC reporting to find out its tone. There is significant concern within the multirotor community that it presents a very one-sided view, and takes at face value the assertion that the sighting was a drone, when in fact there is no proof at all of that being the case. For those of us who have seen many such stories come and go it is difficult not to agree with the drone pilots, there is at best some lazy reporting in the air, and at worst some outright journalistic irresponsibility.

As Hackaday readers, you are used to writers with an in-depth knowledge of the subjects upon which they write. We don’t know all possible facets of technology and we occasionally get things wrong, but we all have very strong backgrounds in the tech, hacker, and maker industries and communities we write about. We have engineering education, we’ve worked in a wide variety of technology industries, we build our own stuff for fun, and we’ve founded and run hackspaces.

By comparison the journalists whose work you will read in the mainstream media are generalists. They will have a specific educational background and a particular set of interests, but in their work they cover whatever stories tumble off the endless conveyor belt of events. Thus when a drone story appears, they find themselves out of their normal comfort zone of politics or local news, and can not rely on their experience to inform their coverage of it. The responsible journalistic approach is to do a little research and ask the pertinent questions asking for concrete proof of drone involvement. We’re still waiting for that to happen in these allege drone encounters.

Multirotor building and flying is a significant feature of our community, and anything that brings the attention of law enforcement to the kind of work we do should be a worry to us all. Multirotors are not the only things covered by Hackaday that could be misrepresented in the same way. We’ve visited this topic before, take a look at our analysis of a series of air proximity reports blamed on drones. Some of them, you couldn’t make up.

Automate The Freight: Front Line Deliveries By Drone

Gen. Robert H. Barrow, USMC, once said that “Amateurs talk about tactics, but professionals study logistics.” That’s true in many enterprises, but in warfare, the side that neglects logistics is likely to be the loser. Keeping soldiers fed, clothed, and armed is the very essence of effectively prosecuting a war, and the long logistical chain from rear supply depots to forward action is what makes that possible.

Armies have had millennia to optimize logistics, and they have always maximized use of new technologies to position supplies where they’re needed. Strong backs of men and beasts sufficed for centuries, supplemented by trains in the 19th century and supplanted by motor vehicles in the 20th. Later, aircraft made an incalculable impact on supply chains, allowing rapid mobilization of supplies and supporting the industrial scale death and destruction of the 20th-century’s wars.

Drone Takes Off With A Flick Of The Wrist

June 18, 2017 by 8 Comments

One of the companion technologies in the developing field of augmented reality is gesture tracking. It’s one thing to put someone in a virtual or augmented world, but without a natural way to interact inside of it the user experience is likely to be limited. Of course, gestures can be used to control things in the real world as well, and to that end [Sarah]’s latest project uses this interesting human interface device to control a drone.

The project uses a Leap Motion sensor to detect and gather the gesture data, and feeds all of that information into LabVIEW. A Parrot AR Drone was chosen for this project because of a robust API that works well with this particular software suite. It seems as though a lot of the grunt work of recognizing gestures and sending commands to the drone are taken care of behind-the-scenes in software, so if you’re looking to do this on your own there’s likely to be quite a bit more work involved. That being said, it’s no small feat to get this to work in the first place and the video below is worth a view.

To some, gestures might seem like a novelty technology with no real applications, but they do have real-world uses for people with disabilities or others with unusual workflow that require a hands-free approach. So far we’ve seen hand gesture technologies that drive cars, help people get around in the physical world, and even play tetris.

Automate The Freight: Maritime Drone Deliveries

June 6, 2017 by 50 Comments

Ships at sea are literally islands unto themselves. If what you need isn’t on board, good luck getting it in the middle of the Pacific. As such, most ships are really well equipped with spare parts and even with raw materials and the tools needed to fabricate most of what they can’t store, and mariners are famed for their ability to make do with what they’ve got.

But as self-sufficient as a ship at sea might be, the unexpected can always happen. A vital system could fail for lack of a simple spare part, at best resulting in a delay for the shipping company and at worst putting the crew in mortal danger. Another vessel can be dispatched to assist, or if the ship is close enough ashore a helicopter rendezvous might be arranged. Expensive options both, which is why some shipping companies are experimenting with drone deliveries to and from ships at sea. Continue reading “Automate The Freight: Maritime Drone Deliveries” →

The Tri Rotor Drone: Why Has It Been Overlooked?

If you are a watcher of the world of drones, or multirotors, you may have a fixed idea of what one of these aircraft looks like in your mind. There will be a central pod containing batteries and avionics, with a set of arms radiating from it, each of which will have a motor and a propeller on its end. You are almost certainly picturing a four-rotor design, such as the extremely popular DJI Phantom series of craft.

Of course, four-rotor designs are just one of many possible configurations of a multirotor. You will commonly see octocopters, but sometimes we’ve brought you craft that really put the “multi” in “multirotor”. If the computer can physically control a given even number of motors, within reason, it can be flown.

There is one type of multirotor you don’t see very often though, the trirotor. Three propellers on a drone is a rare sight, and it’s something we find surprising because it’s a configuration that can have some surprising benefits. To think about why, it’s worth taking a look at some of the characteristics of a three-rotor machine’s flight.

FAA’s Drone Registration System Struck Down For Hobbyists

May 20, 2017 by 76 Comments

The US Court of Appeals for the D.C. Circuit has struck down a rule requiring recreational drone users and model aircraft pilots to register their drones with the FAA.

This began when [John Taylor], an RC hobbyist and attorney, filed suit against the FAA questioning the legitimacy of the FAA’s drone registration program. This drone registration began early last year, with the FAA requiring nearly all drones and model aircraft to be registered in a new online system. This registration system caused much consternation; the FAA Modernization And Reform Act of 2012 states, ““…Federal Aviation Administration may not promulgate any rule or regulation regarding a model aircraft…”, defining model aircraft as any unmanned aircraft flown within visual line of sight for hobby or recreational purposes. Despite this mandate from Congress, the FAA saw fit to require registration for every model aircraft weighing between 0.55 and 55 pounds, regardless of the purpose of its flight.

In our coverage of the FAA’s drone registration program, we couldn’t make heads or tails of the reasons behind this regulation. In addition to the questionable legality of this regulation, there are questions over the FAA’s mandate to regulate anything flying under the 400 foot ceiling cited in the FAA’s rules. The question of safety is also open — a 2 kg drone is likely to cause injury to a passenger on a commercial flight only once every 187 million years of operation. In short, the FAA might not have the mandate of managing the air traffic, certification, and safety of the nation’s airspace when it comes to model aircraft.

While the Circuit court struck down the rule for registration concerning model aircraft, this still only applies to small (under 55 pounds) planes and quads flown within line of sight. Commercial drone operators still fall under the purview of the FAA, and for them the drone registration system will stand.

Automate The Freight: Medical Deliveries By Drone

Being a cop’s kid leaves you with a lot of vivid memories. My dad was a Connecticut State Trooper for over twenty years, and because of the small size of the state, he was essentially on duty at all times. His cruiser was very much the family vehicle, and like all police vehicles, it was loaded with the tools of the trade. Chief among them was the VHF two-way radio, which I’d listen to during long car rides, hearing troopers dispatched to this accident or calling in that traffic stop.

One very common call was the blood relay — Greenwich Hospital might have had an urgent need for Type B+ blood, but the nearest supply was perhaps at Yale-New Haven Hospital. The State Police would be called, a trooper would pick up the blood in a cooler, drive like hell down I-95, and hand deliver the blood to waiting OR personnel. On a good day, a sufficiently motivated and skilled trooper could cover that 45-mile stretch in about half an hour. On a bad day, the trooper might end up in an accident and in need of blood himself.
