UK Government To Hold Drone Licensing Consultation

All over your TV and radio this morning if you live in the UK is the news that the British government is to hold a consultation over the licensing of multirotors, or drones as they are popularly known. It is being reported that users will have to sit a test to acquire a licence before they can operate any machine that weighs above 250 g, and there is the usual fog of sloppy reporting that surrounds any drone story.

This story concerns us on several fronts. First, because many within our community are multirotor enthusiasts and thus we recognise its importance to our readership. And then because it takes as its basis of fact a series of reported near misses with aircraft that look very serious if taken at face value, but whose reported facts simply don’t match the capabilities of real multirotors. We’ve covered this issue in the past with an incident-by-incident analysis, and raised the concern that incident investigators behave irresponsibly in saying “It must have been a drone!” on the basis of no provable evidence. Indeed the only proven British collision was found to have been with a plastic bag.

Of course irresponsible multirotor fliers who threaten public safety should be brought to book. Lock them up, throw away the key, whatever is appropriate. But before that can be done, any debate must be conducted on a level playing field. Our final concern is that this is an issue which is being framed almost entirely on the basis of one side’s interest groups and hysteria on the part of the uninformed about a new technology, rather than a balanced examination of the issues involved. It’s the old “People are having fun. This must be stopped!” idea that infects so much lawmaking, and it’s not very pretty.

Fortunately while it is being reported in some quarters as a done deal as in “Drone fliers must sit a test”, in fact this story is “The Government will ask people what they think about drone fliers sitting a test”. It’s a consultation, which means a Parliamentary committee will sit down and hear evidence before deciding on any legislation. The good news about consultations is that they are open to submissions from the general public, so if you are a British multirotor flier you can submit your own arguments. We will keep you posted with any news about the consultation as we have it.

A DIY Net Gun To Catch Whatever You Want

Suspicious drones hovering about your property? Burglars or other ne’er-do-well test subjects giving you trouble? Need to catch a dog that keeps meandering through your workshop? [William Osman] suggests you build yourself a pneumatic net gun that can shoot 20-30 feet to catch them all.

The net gun is built largely out of PVC pipe; the air tank — filled via a tire valve — uses adapter fittings to shrink it down to a 1″ sprinkler valve, with an air gun to act as a trigger. The net launcher is made of four lengths of pipe bent with the use of a heat gun — an Occam’s Razor solution compared to his first attempt — and is coupled to the end, while the net loads in using wooden dowels with washers as weights. It won’t trap any large game, but it will certainly net you some fun.

Be Your Own Google Mapper

Google Maps is one of the modern wonders of the world. It is hard to remember how expensive it used to be to get high-quality aerial  images. Of course, you don’t get to pick when they fly over a particular piece of the planet. If you are like [Dennis Baldwin] that’s not good enough. He’s been using his drone to document the construction of a high school stadium.

[Dennis] uses the open-source GDAL tools to create Google Map tiles from drone imagery. Even better, he’s documented the process in the video you can find below. Once you can make your own map tiles, you can control when you take the images — important if you are documenting construction like [Dennis] did.

Make Use Of Your Drone Video With WebODM

If you ever watch the original Star Trek, Captain Kirk and crew spend a lot of time mapping new parts of the galaxy. In fact, at least one episode centered on them taking images of some new part of space. It might not be new, but if you have a drone, you probably have accumulated a lot of frames of aerial imagery from around your house (or wherever you fly).

WebODM allows you to create georeferenced maps, point clouds and textured 3D models from your drone footage. The software is really an integration and workflow manager for Open Drone Map, which does most of the heavy lifting.

Lighthouse Locates Drone; Achieves Autonomous Battery Swap

The HTC Vive’s Lighthouse localization system is one of the cleverest things we’ve seen in a while. It uses a synchronization flash followed by a swept beam to tell any device that can see the lights exactly where it is in space. Of course, the device has to understand the signals to figure it out.

[Alex Shtuchkin] built a very well documented device that can use these signals to localize itself in your room. For now, the Lighthouse stations are still fairly expensive, but the per-device hardware requirements are quite reasonable. [Alex] has the costs down around ten dollars plus the cost of a microcontroller if your project doesn’t already include one. Indeed, his proof-of-concept is basically a breadboard, three photodiodes, op-amps, and some code.

His demo is awesome! Check it out in the video below. He uses it to teach a quadcopter to land itself back on a charging platform, and it’s able to get there with what looks like a few centimeters of play in any direction — more than good enough to land in the 3D-printed plastic landing thingy. That fixture has a rotating drum that swaps out the battery automatically, readying the drone for another flight.

If this is just the tip of the iceberg of upcoming Lighthouse hacks, we can’t wait!

How Many Drones Does It Take To Screw In A Lightbulb?

Imagine. There you are, comfortable in your lounge pants. Lounging in your lounge. Suddenly in the distance you hear a buzzing. Quiet at first, then louder. A light bulb goes on in your head.

You forgotten that you’d scheduled an Amazon drone repair service in partnership with The Home Depot and Dewalt. They break through the window, spraying you with shards. They paint the spots on the walls. Snap photos of the brands in your closet. Change the light bulbs. Place a bandaid on your glass wounds. Pick up the shards and leave. Repairing it on their way out.

Horrible.

Of course the first step before this dark future comes to be is to see if it can be done; which is what [Marek Baczynski] and a friend accomplished many broken light bulbs later. Using an off the shelf drone with three springy prongs glued to the top they try time and time again to both unscrew and screw in a light bulb. They try at first with a lighter drone, but eventually switch to a more robust model.

After a while they finally manage it, so it’s possible. Next step, automate. Video after the break.

Automate The Freight: Robotic Deliveries Are On The Way

Seems like all the buzz about autonomous vehicles these days centers around self-driving cars. Hands-free transportation certainly has its appeal – being able to whistle up a ride with a smartphone app and converting commute time to Netflix binge time is an alluring idea. But is autonomous personal transportation really the killer app that everyone seems to think it is? Wouldn’t we get more bang for the buck by automating something a little more mundane and a lot more important? What about automating the shipping of freight?

Look around the next time you’re not being driven to work by a robot and you’re sure to notice a heck of a lot of trucks on the road. From small panel trucks making local deliveries to long-haul tractor trailers working cross-country routes, the roads are lousy with trucks. And behind the wheel of each truck is a human driver (or two, in the case of team-driven long-haul rigs). The drivers are the weak point in this system, and the big reason I think self-driving trucks will be commonplace long before we see massive market penetration of self-driving cars.
