Being Pestered By Drones? Buy a Drone-Hunting Drone

schwit1 writes, "Are paparazzi flying drones over your garden to snap you sunbathing? You may need the Rapere, the drone-hunting drone which uses 'tangle-lines' to quickly down its prey." From The Telegraph's article: It has been designed to be faster and more agile than other drones to ensure that they can't escape - partly by limiting flight time and therefore reducing weight. “Having worked in the UAS industry for years, we've collectively never come across any bogus use of drones. However it's inevitable that will happen, and for people such as celebrities, where there is profit to be made in illegally invading their privacy, there should be an option to thwart it,” the group say on their website. This seems more efficient than going after those pesky paparazzi drones with fighting kites (video), but it should also inspire some skepticism: CNET notes that the team behind it is anonymous, and that "Rapere works in a lab setting, however there aren't any photos or videos of the killer drone in action. The website instead has only a slideshow of the concept."

There was that old sf story by Robert Silverberg, I think, that went like this: They made automated police drones (they weren't called drones back then) that prevented any violent crime from happening. Unfortunately they had learning circuits and decided even killing animals for food or harvesting crops was violent crime, and the society ended up starving. The solution was to create a new kind of drone to kill the existing drones - but this also had learning circuits and it decided it had to kill everyone.
Looks pretty realistic these days. Anyone remember the name of the story, and the author if i got it wrong?

If there's a drone hovering over my land, or my 'charge' if I am hired security, it is guilty until proven innocent.

We did not build fences and walls -- and for that matter -- start wearing clothes, only to keep out the weather. We developed personal boundaries and we even invisibly project them around us when we move. If you've ever been asked "What're YOU lookin' at?" by someone, you know this even extends to where you are gazing in public. A common stumble in across cultures is violating staring rules. Expected behavior and perceived intent matters.

One of our sharpest instinctive startle-reactions is the sudden appearance of eyes in places where eyes were not expected, or where eyes should not be. This has evolved with us from a predator mechanism, where swift action becomes necessary, and it is why spotting glowing eyes around a campfire generates a moment of apprehension. Modern humans have correctly characterized drones as eyes in the sky. Unlike helicopters which strive to spend their time beyond the dead man's curve drones are close and personal and quiet.

You can also follow this eyes in the sky phenomenon in history. Even friendly nations felt it necessary to go on alert when their neighbors unexpectedly entered their airspace for reconnaissance flights, and during the Cold War these incursions were considered acts of war. The Treaty On Open Skies was the culmination of 50 year effort to declare aerial surveillance a mutually beneficial activity. Originally proposed by Eisenhower, this treaty was like a 'cease and desist' order for those who sought to keep aerial photography out of reach of the common man, just as there are those who would try to keep secure encryption from the public, oh holy shit President Obama why are you starting this Clipper crap again, sorry about that, and has paved the way for the Google Earth we all know and love to browse.

Interestingly the treaty limits its signatories' ground resolution to 30 centimeters. Enough to count fighter planes but not good enough to gawk at bathing beauties.

So scale this eyes where eyes are not supposed to be thing down to the personal level as part of a right to privacy. The problem is that predatory paparazzi are assholes and bullies, and the people who read tabloid magazines are their silent enablers. For every measure, a suitable countermeasure. That is the market, and you can bet if I was on a security detail one of these would be on my Xmas list.

If you are comforted to be watched over by machines of loving grace... smile, you're on Candid Camera.

It's not legal to throw a rock in a city area if you don't know where it will land, and by the same token, it's not legal to fire even an airgun into the sky if you don't know where the projectile is coming down.

Re:Solution looking for a problem

An air rifle would be fine for city use. A BB has next to no kinetic energy by the time it returns to the ground. Air resistance is a real energy sapper for things that small.

A thrown rock or a slung projectile will be larger and more massive and so retain more of its kinetic energy on return. The attacked drone falling from the sky will do more potential damage than any of the projectiles you'd use to bring it down.

I'd lay odds that the Secret Service will be their first customer because unidentified drones cannot be tolerated in their controlled area, and they try to avoid sniping things unless a clear threat is in progress.

It's a cryin' shame that Deer Trail, Colorado voted down its proposed $25/year drone hunting license. Of 181 votes cast ~73% were against. This makes perfect sense to me, because at any point in history it seems only ~25% of any given population seems able to spot and move against certain trends that would take us down a bad road. And I'm not just talking about the guv'mint.

Up to now paparazzi, peeping toms and criminals casing potential victims and whole neighborhoods have had to grace their target areas with their physical presence, which has held them greatly in check.

I'm sure many are excited at the prospect of Amazon deliveries and pizzas buzzing through the skies -- or just exploring -- just for the novelty of how cool it would be. Hell, whole generations of us were enthralled by the "drone footage" at the beginning of Mr. Rogers' Neighborhood and how it would show a bird's eye view as he left home to visit his neighbors. Or perhaps you imagine something like this. Reality is a lot messier as they become commonplace. Drone operators will be watching their objectives on the ground and zooming their lenses as they fail to spot each other, power lines and aviation.

They will be crashing down onto busy roadways. As their payloads become heavier and their motors stronger there is potential for real harm to bystanders. When signal is lost or power is low they will go into autonomous descent without regard to the hazards below (such as fast moving traffic). It is inevitable that the use of 'cheap' drones is to become a favored method of terrorists. All of these things will happen by degrees.

We put pilots through the wringer and hold aircraft to ultra-high standards of reliability for good reason. We must not brush these things off lightly, and allow the the skies to become filled moving with objects of unknown purpose and origin. Unless we are really, really excited about putting pizza delivery folk out of work.

Re:Solution looking for a problem

[drinkypoo]

An air rifle would be fine for city use. A BB has next to no kinetic energy by the time it returns to the ground.

it also has next to no kinetic energy when it strikes something on the way out, too, unless it's very close. that's why we use pellets. and unless those are pointy, they won't really serve. A .177 pointed pellet is actually pretty useful. I don't think they're heavy enough to be dangerous coming down either, but they're still heftier than a BB. And besides, there are .22 caliber air guns. Fire one of those at a shallow enough angle, and it might be dangerous. But the law doesn't differentiate; if you don't know where the projectile will come down, it's illegal to fire, whether it's a toy airgun or a real airgun or a real firearm.

Focused EMP at said drone. Make it so!

Re:Solution looking for a problem

[__aajfby9338]

But wouldn't that shot/pebble-like-stuff fall and potentially hurt someone?

I don't think that birdshot is dangerous on the way back down, unless a pellet falls right into your upturned eye. It has enough kinetic energy to harm a bird (or fragile drone) within some range of the shooter, but by the time it comes back down it has slowed to terminal velocity. Birdshot is only around a millimeter in diameter, like coarse sand. The "pebble-like-stuff" would be buckshot, which would not be practical to use against a bird/drone because not many pellets of that shot fit in a shell, making it pretty hard to actually hit a flying target with at least one pellet.

Despite the relative safety of falling birdshot, firing guns into the air in urban settings is generally frowned upon. :)

Re:Solution looking for a problem

[Harlequin80]

Even larger calibre ammunition poses limited threat. A 7.62 round (think AK47) has a terminal velocity of around 90m/s and weighs around 200g (depending on the round you use). That combination is right on the lower limit of power needed to break the skin if it struck with the point. What actually happens, in most cases, is the bullet twists and ends up flying sideways so you have a larger impact point making it significantly less harmful.

Smaller calibre bullets have a much lower terminal velocity and have a lighter mass so they pose even less of a risk.

So in summary if a falling 7/62 round landed on your head it would hurt, probably quite a lot, but that would be about it. The birdshot referred to above, I actually am not even sure you would notice it. The cloud would be so dispersed by the time it fell to the ground that even if it hit you in the eye you would probably think it was an odd shaped bit of sand.

Re:Solution looking for a problem

[Harlequin80]

I was kinda assuming that deploying a hunter/killer drone and having at least 1 potentially 2 sizable devices falling out of the sky was illegal already.

You chances of being caught as the person who fired a marble out of a slingshot or a air rifle pellet are probably lower than being cause as the owner of your hunter/killer.

Slingshot for me would be the most fun I think. You could mess around with different pellet designs, like making a fishing line let and firing a wad of 12 small fishing weights. Would that deploy as a net or would it just stay as a clump?

Re:Solution looking for a problem

[bugnuts]

People die every year from falling bullets previously shot up in the air, and hundreds more are injured. That said, birdshot won't hurt you coming down. You might notice it, but probably doesn't even have as much force as a light hail.

Lots of references on falling bullets on the wiki article on it.

Re:Solution looking for a problem

[Harlequin80]

If you go through the cited articles there you will see that almost all of them are people who are hit while the bullets are on the way up or the bullet was fired at a sub 45 degree angle.

Even the Puerto Rico CDC link which is used as the primary source material starts by saying that it is based on media reports. That page seems to conflate injuries sustained through "celebratory gunfire" and bullets falling from the sky. People get shot when someone does something stupid with a weapon. However the physics behind whether a falling bullet will cause serious injury are able to be calculated fairly well.

I'm not saying firing a 7.62 round into the air is without risk. But the chances of serious injury are very low.

As for birdshot, No.10 grains are 0.032 grams and there are 850 of these balls per cartridge. Effective range for killing a pigeon is about 20m. Past 50m and you have no chance, and this is when it is driven under force from a shot gun.

I have no idea what the terminal velocity of something that weighs that little and has a diameter of 1.75mm is. But it would be safe to say, not very high. If I took a fist full of those pellets and dropped them from a 30 storey balcony on a crowded street below I would suggest most people wouldn't even notice. It sure as hell isn't going to have the force of light hail. More so if there is a slight breeze and the cloud is dispersed on the way down.

Re:Solution looking for a problem

[CaptQuark]

I'm not saying firing a 7.62 round into the air is without risk. But the chances of serious injury are very low.

Based on anecdotal evidence from Mythbusters testing, the determining factor seemed to be if the bullet maintains a stable spin. Once the bullet starts tumbling, it loses speed quickly and it becomes less damaging. http://mythbustersresults.com/...

Even shotgun pellets used in duck and pheasant hunting (Size 6 shot or less than 3mm) don't hurt when falling back to earth. I've been on a few pheasant hunts where hunters accidentally shoot upward toward another group of hunters and the falling shot does nothing more than sting when coming back down.

That said, shooting quadcopters with a shotgun is a TERRIBLE idea.

Re:Solution looking for a problem

Re:Solution looking for a problem

[Harlequin80]

And I don't see any way the bullet would retain a stable alignment. As soon as its spin speed dropped it would have to remain perfectly angled through the air with never a breath of air pressure differential. A momentary change in pressure on one edge, let alone a gust of wind, will cause it to tumble.

You can see if with .22lr rounds on a 200yd range. Sometimes your bullet will have tumbled before reaching the target

I have said it before and I'll say it again: I'm amazed noone has taken a consumer-grade self-built multicopter, put a pound of plastic explosive on it, and flown it into or next to an important building from a mile away.

Building a quadcopter or such capable of carrying a lethal payload and flying it FPV takes about $250-300.

Re:Inevitible

[Harlequin80]

That type of attack would be very unlikely to cause any structural damage. You would not be able to get close enough to the walls so you will only get splash impact.

It would be a useful anti-personnel weapon but your payload is always going to be cripplingly small for the cost. If you are someone with access to plastic explosive you probably have access to mortars. A mortar will have a much longer range and deliver a much greater payload. In addition it actually strikes the building before detonation rather than being 1+ meters away meaning much greater chance of causing a structural failure.

Re:Inevitible

[DarkOx]

Probably because most of the terrorists are not thinkers. These guys are still trying to set off some m80s in the back of a car next to a propane cylinder and expecting something exiting to happen. Essentially they are not smart enough to put something like that together that actually works without help. They are not smart enough to solicit help without getting caught either.

It will happen eventually but its going to have to be some relatively intelligent person who has gone of the deep end for one reason or another. Probably it will be Timothy McVeigh type who does it in a 'western' nation first. The Islamists might do it in Iraq/Yemen/Syria/*istan where their infrastructure is but so far 9/11 and the Subway bombing has been only cases where they recruited actors who are not some combination of overly stupid or overly deranged to successfully pull off something more complex than 'run and gun'.

The other thing is the smarter Islamists know they have a large enough pool of the stupid and deranged that they need only get a handful of AKs into their hands and some ammo and they have a reliable suicide attack. There will be much higher probability of failure trying to deliver IEDs from drones and given current constraints on the tech available at your local hobby shops and hardware store little chance of doing damage that is much greater. So in a sense its 'smarter' to put some AKs into the hands of some baffoon you have convinced is on his way to 72 virgins.

Re:Inevitible

Don't forget that guy in New Zealand who designed and built an inexpensive home-built cruise missile that could be launched from a pickup truck. It wasn't big, but it was effectively unstoppable and theoretically pretty easy to launch and escape without getting caught.

Yes, anti-personnel is the danger. I wouldn't be surprised if the secret service don't already jam potential drone control frequencies for their high-value people.

The complexity involved in *using* these tools, pales in comparison to developing them. All it would it take is getting an impressionable kid to design it.

*I only mention the pakistani/arab aspect because perhaps they'd be more sympathetic to a terrorists point of view to begin with. Before someone cries out 'racism' -- bear in mind just because something is uncomfortable to think, doesn't necessarily mean it's wrong.

The suicide guys? Yeah, they're the ones who can be persuaded that dying is worth it. But 'terrorist' by now encompasses such a large group, there are going to be plenty of people capable of planning a complex attack.

One guy with a few drones remotely piloted on a common frequency, say 433MHz, carrying pipe bombs onto school playgrounds cannot easily be stopped. Where this same guy with an AK47 can be stopped with a single bullet.

Re:Inevitible

Look at any engineering program in the US -- how many pakistani / arab students are there? How hard would it be for someone actually motivated to use such a device to find one of these students who either already had resentment towards the west, or had family back home who could be used as leverage?

Impossible no, but there is always going to be risk in a free society. I suspect there are not that many engineering students that take the 72 virgins stuff literally, and more than there are those who fear going into the woods because Satan might be waiting. They are engineering students because they have talent, aspirations, and opportunity. Could they use that opportunity to be a suicide terrorist, yes they could, but most of them certainly feel they worked hard to get where they are and want something better for it than to die young. Long story short they are like you or I.

The use their family as leverage part is probably more realistic. Hard to say what someone will do if you tell them you are holding their sister who you will rape to death if they don't follow instructions, but that is still unlikely. That would require these guys have operatives to identify Arab students who they can trace family back to a home country where they can grab them and hold them. Conditions must be such that the victim would need to believe going to the authorities won't work. If its Saudi Arabia or something where the state department can make a few phone calls and get someone picked up, that is probably how that will go.

I am all for tightening up our boarders and strictly enforcing our immigration laws. We should close the tourism visa loop hole. We should make sure everyone who comes here from abroad gets background check and people with criminal backgrounds including things that we consider felonies should be denied; as should those who have known militant associations. We should locate and deport people who let visa's expire quickly; no excuses. Being out of immigration compliance should result in being permeately bared from entry to all US territories in the future.

What we don't need/want to do is get all twitchy and suspicious about folks here. If they came here legal and are obeying the same laws you and I obey we should treat them like we treat each other. This is important for our society, its kinda what America is supposed to mean.

It's not legal to fly a drone over property without permission, it's not legal to film a property without permission. Also, it's your drone, so you are responsible to whatever happens if it crashes.. You can try to sue the person who damaged your drone while it was over his/her property, but I'm pretty sure you'll loose...

laser

[confused one]

You guys are going about this all wrong. Combine a targeting system with a decent laser and you can blind the camera and kill the drone at the same time. No need for dueling drones. Just make sure your system can tell the difference in a passenger aircraft or helicopter and a drone... It could go badly if you manage to punch holes in a police helicopter.

Seems like jamming would be easier

[CityZen]

Most drones operate using either 2.4 or 5.8Ghz frequencies for control. Seems like downing a drone just requires a RF jammer with a directional antenna. I suppose that the targeted drone can still get up again once you stop jamming it, so that's a difference compared to the fighting drone.

I also suppose this wouldn't block drones that were set to operate autonomously.

Re:Seems like jamming would be easier

[bugnuts]

Intentionally jamming an RF signal, even if you think it's illegally over your own property (which is also debatable), is a federal crime.

Section 333 of Title 47

No person shall willfully or maliciously interfere with or cause interference to any radio
communications of any station licensed or authorized by or under this chapter or operated by
the United States Government.

Section 302 prevents selling such equipment.

There are about 5 bands that model aircraft use, and they are narrow bands. You'd have to not only jam several bands, but it would be a reckless "overjamming" in order to guarantee catching it. If you shut it down, you may also shut down all nearby wifi, CBs, and so on. It could land you a significant fine, possibly jail, and maybe even property damage for the drone along with an injunction.

Re:Seems like jamming would be easier

[CaptQuark]

Don't forget that all RC systems operating in the 2.4GHz range use Spread Spectrum features specifically to prevent interference. The transmitter and receiver are "bound" together so the receiver can ignore all signals not coming from the bound transmitter.

Jamming a single frequency would only result in the loss of a few frames of control signals before the TX/RX would move on to the next frequency.

Re:Seems like jamming would be easier

[CityZen]

It's not clear to me that the wording above applies to wifi frequencies. But in any case, in order to "jam" wifi, you don't need an illegal "jammer", you could use a wifi station that broadcasts strong signals across multiple channels.

Re:Seems like jamming would be easier

[CityZen]

Not all RC systems use spread spectrum. (The very popular DSM2 doesn't.) Those that use wifi don't either. Also, most video transmitters are single frequency. In any case, the 2.4Ghz band is fairly narrow. With only 3 wifi channels, you can cover most of it.

Re:Seems like jamming would be easier

[CaptQuark]

Actually the DSM2 does use Spread Spectrum. It uses DSSS (Direct Sequence Spread Spectrum) centered around the two most open channels. Trying to jam the center frequency would only be effective until the data shifted into one of the sidelobes. https://www.spektrumrc.com/Tec...

And let the lawsuits commence. Are we taking bet on which Hollywood rag will be the first to post nude images take with RC choppers with cameras?Im betting not only actors and famous people will the only ones raped by the eyes in the sky.

"Only"

[SuperKendall]

drone operators would only need to glue razorblades on the tips of the rotors

Which would Only affect the entry aerodynamic stability of the craft, making it just as likely it would slit the operators throat on launch as it would be to slice through anything, or be controllable at all...

Liability.

[jklovanc]

The second you disable another drone in flight you become liable for any damage it does coming down. If someone gets injured or something gets damaged the owner of the attack drone in on the hook. It could also be considered destruction of private property if what the drone was doing was legal.
