Universities Envision Flying Beetle Swarms; But Crawl Before You Fly

April 12, 2016 by 132 Comments

Researchers at Nanyang Technical University and the University of California at Berkley wanted to answer the question: how do you make a small drone that can fly all day? The problem is that a drone needs a battery or other energy source, but a big battery needs a big drone.

Their answer? Take a giant beetle and strap enough electronics onboard to deliver tiny shocks to direct the insect’s flight. The tiny shocks don’t take much power and once the beetle is on course, no further shock is necessary unless the human pilot needs to correct the direction. Recent work allows a similar controller to control each leg of the beetle, turning it into a more versatile flying or walking cyborg.

FAA Reauthorization Bill Includes Provisions For Hobbyists

March 15, 2016 by 62 Comments

Every year, Congress passes bills directing the funding for various departments and agencies. Sometimes, this goes swimmingly: congress recently told NASA to attempt a landing on Europa, Jupiter’s ice-covered moon. Sometimes, it doesn’t go as well. The draft of the FAA Reauthorization act of 2016 (PDF) includes provisions for drones and model airplanes amid fears of privacy-encroaching quadcopters.

As would be expected, the 2016 FAA Reauthorization act includes a number of provisions for unmanned aerial systems, a class of aircraft that ranges from a Phantom quadcopter to a Predator drone. The draft of the act includes provisions for manufacturers to prevent tampering of modification of their product, and provide the FAA with a statement of compliance, and prohibit these devices from being sold unless these conditions are met.

For a very long time, the Congress and the FAA have had special rules for model aircraft. Since 2012, the special rules for model aircraft have been simple enough: model aircraft are flown for hobby or recreational use, must operate in accordance with community-set safety guidelines, weigh less than 55 pounds, give way to manned aircraft, and not be flown within five miles of an airport. The 2016 FAA Reauthorization bill adds several updates. No model aircraft may be flown higher than 400 feet above ground level, and the operator of a model aircraft must pass a knowledge and safety test administered by the FAA. Under this draft of the FAA Reauthorization bill, you will have to pass a test to fly a quadcopter or model plane.

While this is only a draft of the 2016 FAA Reauthorization bill, there is a considerable risk flying model planes could quickly go the way of amateur radio with a Morse requirement for the license. This, of course, is due to Congress’ fears of the impact drones and model airplanes could have on safety, despite recent studies that show a 2kg drone is likely to cause injury to a human passenger once every 187 million years of operation. In other words, politicians don’t understand statistics.

Bullet-time Video Effect By Throwing Your Phone Around

March 7, 2016 by 43 Comments

Ski areas are setting formal policies for drones left and right, but what happens when your drone isn’t a drone but is instead a tethered iPhone with wings swinging around you like a ball-and-chain flail as you careen down a mountain? [nicvuignier] decided to explore the possibility of capturing bullet-time video of his ski runs by essentially swinging his phone around him on a tether. The phone is attached to a winged carrier of his own design, 3D printed in PLA.

One would think this would likely result in all kinds of disaster, but we haven’t seen the outtakes yet, and the making-of video has an interesting perspective on each of the challenges he encountered in perfecting the carrier, ranging from keeping it stable and upright, to reducing the motion sickness with the spinning perspective, and keeping it durable enough to withstand the harsh environment and protect the phone.

He has open sourced the design, which works for either iPhone or GoPro models, or it is available for preorder if you are worried about catastrophic delamination of your 3D printed model resulting in much more bullet-like projectile motion.

Mini Quadcopter Becomes Paper Airplane

February 20, 2016 by 12 Comments

Several of us got Cheerson CX-10 mini quadcopters last year. We even bought some more to hand out as Christmas gifts. If you haven’t seen them, they are diminutive little flyers about the size of an English muffin. Thee’s no denying they are fun to fly around the house, and they do annoy the dogs.

However, like all cute toys, you eventually get bored just buzzing the dogs and cats. [JustforFun Media TK] decided that his needed a facelift, so he converted it into a paper airplane. This isn’t the paper airplane you folded up in school, either. This is a slick-looking jet aircraft.

Manned Multicopter Project Undaunted By Crash

February 13, 2016 by 97 Comments

We have to be impressed by [amazingdiyprojects] who completely totaled their manned multi-copter build, which has been spanning over eight videos. He explained the crash in video number eight and is right back at it, learning from the recent mistakes.

When you get right down to it, this is as dangerous as this seems. However, a giant multicopter is probably the easiest flying machine for a hobbyist to build. It’s an inefficient brute-force approach, but it sure beats trying to build a helicopter from scratch. This machine is a phenomenally un-aerodynamic chair on a frame that has a lot in common with the lunar rover; with engines on it. Simple.

There are a lot of approaches to this. One of the crazier ones is this contraption with a silly amount of electric motors. [amazingdiyprojects] went with eight gasoline engines. We’re really interested in his method for controlling the rpm of each engine and dealing with the non-linearity of the response from a IC engine throttle. Then feeding that all back into what is probably the exact same electronics from a regular diy drone.

Honestly, we’re surprised it worked, and we can’t wait for him to finish it so we can see him zooming around in his danger chair. Videos after the break.

Thanks [jeepman32] for the tip!

FAA Rescinds Drone Ban Around DC

February 10, 2016 by 31 Comments

Late last year, the FAA expanded a Special Flight Rule Area (SFRA) that applied to Unmanned Aerial Systems, drones, and RC airplanes around Washington DC. This SFRA was created around the year 2000 – for obvious reasons – and applies to more than just quadcopters and airplanes made out of foam. Last December, the FAA expanded the SFRA from 15 nautical around a point located at Reagan National to 30 nautical miles. No remote-controlled aircraft could fly in this SFRA, effectively banning quadcopters and drones for six million people.

Today, the FAA has rescinded that ban bringing the area covered under the Washington DC SFRA to 15 nautical miles around a point inside Reagan National. This area includes The District of Columbia, Bethesda, College Park, Alexandria, and basically everything inside the beltway, plus a mile or two beyond. Things are now back to the way they were are few weeks ago.

The 30-mile SFRA included a number of model flying clubs that were shuttered because of the ban. DCRC is now back up. The Capital Area Soaring Association worked with the FAA and AMA to allow club members to fly.

Of course, limitations on remote-controlled aircraft still exist. For the most part, these are rather standard restrictions: aircraft must weigh less than 55 pounds, fly below 400 feet line of sight, and must avoid other aircraft.

Greased Lightning Shows 360 Degrees

February 7, 2016 by 41 Comments

A lot of people got drones for Christmas this year (and many Hackaday readers already had one, anyway). A lot of these drones have cameras on them. The expensive ones beam back live video via RF. The cheaper ones just record to an SD card that you can download later.

If you are NASA, of course, this just isn’t good enough. At the Langley Research Center in Virginia, they’ve been building the Greased Lightning (also known as the GL-10) which is a 10-engine tilt-prop unmanned aerial vehicle. The carbon fiber drone is impressive, sure, but what wows is the recent video NASA released (see below).
