Tokyo Police Aim To Catch Drones In A Net

December 20, 2015 by Elliot Williams 39 Comments

A Japanese protester flew a quadcopter with a symbolic amount of soil from the contaminated Fukushima region onto the roof of the Prime Minister’s office in April. Although it was a gesture, it alerted the Tokyo police department to the potential need to be able to pull drones out of the air.

Simply shooting them down won’t do — think of the innocent bystanders on the ground subjected to a rain of quadcopter parts. The Tokyo police’s solution: catch them in a net, flown by another quadcopter, of course.

We can’t embed it here, but go click through to the video. It looks like the police are having a really good time. How long before we see drone-net sets under the Christmas tree, or quadcopter-tag leagues? We’re uncertain of how far the Battlebots in the Sky movement got.

We have no shortage of yahoos driving quadcopters in the States, of course. From interfering with fire-fighting aircraft to simply flying too close to commercial airplanes, people are doing things that they simply shouldn’t. We’ve been covering the US government’s response that finally culminated in the FAA making rules requiring medium-weight drones to be registered. Watch our front page for more on that next week. Fly safe, folks.

FAA Releases Rules Governing Unmanned Aerial Systems

December 14, 2015 by Brian Benchoff 127 Comments

The US Department of Transportation and the FAA have just released their guidelines that require registration of Unmanned Aerial Systems. This is the regulation that covers model aircraft, drones, quadcopters, and flying toys of all kinds. These rules have been anticipated since last month to be in place for the holiday season.

As expected, the FAA is requiring registration for all aircraft, regardless of being ‘model’ aircraft or not, weighing more than 250 grams (0.55 pounds) and less than 55 pounds. The maximum weight is a holdover from previous regulations; model aircraft weighing more than 55 pounds were never really legal without a permit. It should be noted that anyone can build a quadcopter with cameras and video transmitters weighing less than 250 grams. These quadcopters are not ‘toys’ by any means, but are not required to be marked with a registration number and the pilot is not required to actually register. As expected, most rules governing the actual flight of these aircraft remain in place – don’t fly above 400 feet, don’t fly within five miles of an airport.

Registration is by pilot, not aircraft, and costs $5. A registration number must be put on every aircraft the pilot owns, and penalties for not registering can include up to $27,500 in civil penalties and up to $250,000/3 years imprisonment in criminal penalties. The full rules are available in this 200-page PDF. As with most government regulations, there will be a 30-day RFQ period beginning December 21st on regulations.gov. The docket number is FAA-2015-7396.

“Who Is John Galt?” Finally Answered

November 22, 2015 by Bryan Cockfield 107 Comments

For those who haven’t read [Ayn Rand’s] philosophical tome Atlas Shrugged, there’s a pretty cool piece of engineering stuffed in between the 100-page-long monologues. Although fictional, a character manages to harness atmospheric static electricity and convert it into kinetic energy and (spoilers!) revolutionize the world. Harnessing atmospheric static electricity isn’t just something for fanciful works of fiction, though. It’s a real-world phenomenon and it’s actually possible to build this motor.

As [Richard Feynman] showed, there is an exploitable electrical potential gradient in the atmosphere. By suspending a tall wire in the air, it is possible to obtain voltages in the tens of thousands of volts. In this particular demonstration, a hexacopter is used to suspend a wire with a set of needles on the end. The needles help facilitate the flow of electrons into the atmosphere, driving a current that spins the corona motor at the bottom of the wire.

There’s not much torque or power generated, but the proof of concept is very interesting to see. Of course, the higher you can go the more voltage is available to you, so maybe future devices such as this could exploit atmospheric electricity to go beyond a demonstration and do useful work. We’ve actually featured the motor that was used in this demonstration before, though, so if you’re curious as to how a corona motor works you should head over there.

Who Is Responsible When Machines Kill?

November 9, 2015 by Will Sweatman 121 Comments

This morning I want you to join me in thinking a few paces into the future. This mechanism let’s us discuss some hard questions about automation technology. I’m not talking about thermostats, porch lights, and coffee makers. The things that we really need to think about are the machines that can cause harm. Like self-driving cars. Recently we looked at the ethics behind decisions made by those cars, but this is really just the tip of the iceberg.

A large chunk of technology is driven by military research (the Internet, the space race, bipedal robotics, even autonomous vehicles through the DARPA Grand Challenge). It’s easy to imagine that some of the first sticky ethical questions will come from military autonomy and unfortunate accidents.

The FAA Wants Your Input On Upcoming Drone Regs

October 22, 2015 by Brian Benchoff 106 Comments

Earlier this week, the US Department of Transportation announced registration would be required for unmanned aerial systems. Yes, drones will be regulated, and right now representatives from the Academy of Model Aircraft, the Air Line Pilots Association, the Consumer Electronics Association and others are deciding which quadcopters, planes, and other aircraft should be exempt from registration.

Now, the US DOT and FAA are looking for consumer’s input. The US DOT is asking the public such questions as:

Should registration happen at point-of-sale, or after the box is opened?
Should registration be dependant on serial numbers? If so, how will kits be registered?
Should certain drones/UAS be excluded from registration? Should weight, speed, maximum altitude, or flight times be taken into account?
Should registration require a fee?
Are there any additional ways of encouraging accountability of drone/UAS use?

Comments will be taken until November 6, with the task force assembled by the US DOT providing its regulations by November 20. The hope for all involved parties is that this system of regulation will be in place for the holiday season. One million UAS are expected to be sold by Christmas.

FAA Suggests $1.9M Civil Penalty Against Aerial Photography Company

October 22, 2015 by Brandon Dunson 13 Comments

An October 6th Press Release from the FAA states that SkyPan International, a Chicago based aerial photography company conducted 65 unauthorized operations over a 2+ year period resulting in a $1.9M penalty. This is by far the most severe penalty the FAA has proposed, the previous leader being $18,700 against Xizmo Media which was issued in September.

SkyPan International isn’t your suburban neighbor’s spoiled brat kid who flies his new octocopter through the neighborhood with his HD camera running in hopes to catch…well, you get the idea. SkyPan has been in the aerial photography game for 27 years and was awarded a Section 333 Exemption from the blanket ban of commercial UAS (unmanned aircraft systems) operation from the FAA in 2015. They also proactively contacted the FAA in 2005, 2008, and 2010 to discuss and suggest technical regulatory parameters. The seemingly civil history between the two entities leaves things in a confusing state, which seems to be par for the course when it comes to UAS.

In case you missed it, we also covered the announcement by the US DOT requiring drone registration.

3D Printed Quadcopter Props

October 21, 2015 by Brian Benchoff 52 Comments

Here’s something that isn’t quite a hack; he’s just using a 3D printer as a 3D printer. It is extremely interesting, though. Over on Hackaday.io [Anton] is creating 3D printable propellers for quadcopters and RC planes. Conventional wisdom says that propellers require exceedingly exacting tolerances, but [Anton] is making it work with the right 3D file and some creative post-processing treatment of his prints.

These 3D printed props are a remix of an earlier project on Thingiverse. In [Anton]’s testing, he didn’t get the expected lift from these original props, so a few small modifications were required. The props fit on his 3D printer bed along their long edge allowing for ease of slicing and removal of support material. For post-processing, [Anton] is using acetone vapor smoothing on his ABS printed design. They come out with a nice glossy sheen, and should be reasonably more aerodynamic than a prop with visible layer lines.

Although [Anton]’s prop is basically a replica of a normal, off-the-shelf quadcopter prop, 3D printing unique, custom props does open up a lot of room for innovation. The most efficient propeller you’ll ever find is actually a single-bladed propeller, and with a lot of experimentation, it’s possible anyone with a well-designed 3D printer could make turn out their own single-blade prop.
