Ei muuten tule onnistumaan ihan heti. Meinaan, että ei mene kauaakaan, että jollekin tulee mieleen ottaa selvää siitä, miten tuollainen saadaan alas.

Aika irrelevanttia miten se tehdään. Tulos vaan on ainakin jonkin tason ilmailuonnettomuus asutulla alueella.

Toki on olemassa pieni mahdollisuus sille, että asutuilla alueilla aletaan räiskimään lentolaitteita kuin villissä lännessä konsanaan, mutta kyllä ongelmat tälle Amazonin idealle ovat puhtaasti teknisiä, ei niinkään ammuskelusta johtuvia. Ammuskeluahan voidaan ehkäistä mm. tekemällä laitteesta mahdollisimman pieni, valitsemalla hyvä "suojaväri", sekä lentämällä mahdollisimman korkealla.

Viittasin nimenomaan tuohon kehitteillä olevana vehkeeseen, joka lentää max. kymmenen mailia kohteeseen eikä ole erityisen pieni. Eikä nyt ole kyse mistään villinlännen touhusta, vaan joku koettaa osua mekkalaa pitävään vempaimeen sen mennessä ohi tai tarvittaessa koettaa virittää sille jonkin esteen, kun tietää sen käyttävän tiettyä reittiä tai toimittavan paketin tiettyyn osoitteeseen.

Jos joku oikeasti haluaa tuollaisen Amazonin ideoiman laitteen tuoda alas, niin siinä kyllä onnistutaan.
Se pitää vaan hyväksyä, ja huomioida liiketoiminnan katteissa.

Mutta kuten sanottua, teknisiä, pääasiassa erilaisia ohjelmistoihin liittyviä esteitä markkinoille tuloon on kosolti. Näkisin nämä paljon suurempana murheenkryyninä kuin satunnaiset tihutyöt.

Ja tuossa tulee esille vielä yksi tapa jolla tuoda se alas.
 
No ottaen huomioon että ihan tavalliset lähettifirmojen pakutkin ovat olleet oivallisia keikkakohteita, en ihmettelisi miksi esimerkiksi amazon haluaa siirtyä yhä pienempiin yksittäisiin lähetyksiin.
 
Miten kauan kestää ennenkuin moderni tero käyttää Amazonin lähetystä suorittamaan tihutöitä?
 
Ans nyt katsoon, jotta toimiiko tämä linkki. Mutta Domino's pizza meinaa käyttää UAV:tä toimituksiin.

Serial hacker Samy Kamkar has released all the hardware and software specifications that hobbyists need to build an aerial drone that seeks out other drones in the air, hacks them, and turns them into conscripted army of unmanned vehicles under the attacker's control.

Dubbed SkyJack, the contraption uses a radio-controlled Parrot AR.Drone quadcopter carrying a Raspberry Pi circuit board, a small battery, and two wireless transmitters. The devices run a combination of custom software and off-the-shelf applications that seek out wireless signals of nearby Parrot drones, hijack the wireless connections used to control them, and commandeer the victims' flight-control and camera systems. SkyJack will also run on land-based Linux devices and hack drones within radio range. At least 500,000 Parrot drones have been sold since the model was introduced in 2010.

Melko perusteellinen selvitys siitä miten kävisi quadkopterille haulikon latinkia vastaan.

So no, there will not be an electric quadcopter delivery drone delivering your Cyber Monday packages in 2015: nor even in 2025, most likely, as even Jeff Bezos more or less openly admits if you look at what he actually said.

Yes, there are homes to be found - more of them perhaps in United States than in other places - where electric quadcopters of today could make a safe delivery. All you need is a largish bit of accessible open space that is your own property, airspace above in which the drone is allowed to fly, and some kind of infrastructure to boost the aircraft's GPS accuracy to the sub-metre range. This could be a beacon of your own, or a differential-GPS station quite far away, various other things.


Even in the US, though, not that many people live in homes with acceptably large bits of private land attached or convenient, large, flat roofs etc. Even fewer live under airspace that might be open for unmanned traffic any time soon.

And the real killer is that while some American homes do exist where a quadcopter either could deliver now - or anyway might be allowed to at some point relatively soon - very, very few such homes now lie within effective electric-quadcopter range of any sort of distribution warehouse, Amazon or not. Not many such homes can actually fit into the circle that such aircraft can reach from a given point, even if a warehouse was there - which it will not be, by definition, because not many people are living nearby.

So, no, not happening soon even if you do have a large garden, driveway, forecourt etc and happen to live somewhere remote enough that the airspace above is or might be unrestricted.

But there is one thing that Mr Bezos and his putative drone fleet don't need to worry about. That's irate gun owners beneath their flight path shooting the aircraft out of the sky.

These days it's standard: some drone story or other goes large - police, Feds, Amazon, whatever. The next day in gun-heavy states, the local reporters look up some reliable gun firebrand, who reliably states that the first time he sees a damn drone above his property, out will come his trusty duck gun and blam - no more drone.

Except that's no more credible than the sky-fulla-drones idea in the first place.

Our man with the shotgun is not much up on drones, of course, and the reporter is not much up on guns or probably drones either. But if either knew a few basic facts about both, he would see that trying to shoot down drones with any weapon a normal American might have about the house is a non-starter.

Our shotgun-owning American is fairly likely to be a duck or other wildfowl hunter, though, so he would admit that hitting and bringing down a flying bird isn't likely much beyond 40 yards slant range using modern steel shot, or much beyond 50 no matter what using any kind of shotgun ammo*.

A quadcopter is on the same rough speed and size scale as a wildfowl, and rather less vulnerable if anything: most can keep flying having lost a rotor disc, while a bird can't keep going having lost one wing.

And, crucially, a quadcopter has no reason whatever not to be flying at least 300 feet above the ground for almost all of its journey, most probably much more: well out of practical shotgun range.

And our gun-fancying US resident would not, of course, claim in public that he could hit fast moving flying targets (other than by fluke) using his rifle - because his mates would laugh at him. Shotguns can knock down birds (or drones, maybe) within 40 yards because they throw a "pattern" or cloud of projectiles some of which may hit the target despite the difficulty of the task. Rifle bullets remain effective over much longer distances, but hitting a small fast-moving faraway target with a single bullet isn't practical and nobody even tries.

In a military context you might hit and cripple something very large, pretty close and relatively slow - like a manned helicopter landing or taking off, maybe - by firing rifle bullets rapidly at it out of a machine gun and adjusting the tracers onto target. Mostly you'd rather have a heat-seeking missile or full-blown antiaircraft cannon even for that sort of job.

Even in the States, a weapon that can shoot full-fat rifle bullets (as opposed to more common and considerably less ballistically potent intermediate-power rounds such as 5.56mm) on full auto - sustainably, without the barrel melting, remember - is not simply obtained. Even in the US, tough-talking fellows who have managed to get hold of such a gun may not have backyards isolated enough that they can safely start loosing off full-power rifle ammo into the sky without upsetting the neighbours and/or Feds, cops etc. The bullets will be coming down miles away.

And of course if you do have such a backyard, drones will not be able to reach it to fly over it anyway.

So, sure. Drone delivery isn't happening. But if it does, nobody is going to be shooting the drones down. ®

Ei mikään. Ja jotenkin veikkaan, että sinne lähettämöön ei ole niin vaikea päästä töihin, etteikö se terroristeilta onnistuisi.
 
A US Navy submarine has managed to launch a reconnaissance drone without surfacing, a technique that could revolutionize the ability of submersibles to reconnoiter – or to wreak havoc.

The drone, snappily entitled the eXperimental Fuel Cell Unmanned Aerial System (XFC UAS), was launched from the vertical missile tubes of a Los Angeles class attack submarine, the USS Providence. Coincidentally, the submarine – nicknamed "Mighty P" – was the first submarine of its type to be fitted with vertical launch tubes, originally designed for anti-ship missiles.

The fuel cell-powered drone was encased in a Sea Robin launch vehicle which fell away once the payload breached the surface, whereupon the drone's wings folded out for flight. During Thursday's test the drone flew for more than two hours while broadcasting video back to the submarine, but it has the endurance to fly for six hours at a time.

"This six-year effort represents the best in collaboration of a Navy laboratory and industry to produce a technology that meets the needs of the special operations community," said Dr. Warren Schultz, program manager at the Naval Research Laboratory.

"The creativity and resourcefulness brought to this project by a unique team of scientists and engineers represents an unprecedented paradigm shift in UAV propulsion and launch systems," Schultz said.

The drone launch is part of the Navy's plan to expand the capabilities of its submarine fleet. While subs can gather intelligence on their surroundings using sonar or acoustics, the ability to get a birds-eye view of the surrounding oceans could be very useful for combat or reconnaissance. ®
 
n a robotic twist on American Gladiators, 17 robots and their teams will descend upon Florida this week to see which ones have the greatest superhero potential.

DARPA, the Pentagon’s research wing, is turning to robots to respond alongside humans when there’s a natural or human-made disaster — an initiative that DARPA says was triggered by the 2011 earthquake in Japan that caused the Fukushima nuclear power plant disaster.

At the DARPA Robotics Challenge (DRC) Trials Friday and Saturday at the Homestead Miami Speedway in Homestead, Fla., robot prototypes will be run through a challenge course consisting of eight tasks to evaluate robots’ perception, autonomous decision-making, mobility, dexterity and strength — all the qualities DARPA expects robots would need to work in disaster scenarios.

Speed, however, is not one of the qualities that will be tested. Robots will be given 30 minutes to perform each of the eight tasks once over the course of the two-day event, although DARPA expects that not all of the teams will be able to complete every task.

“We know the robots are slow and unsteady at this point—they’re much like a one-year-old human in terms of locomotion and grasping abilities and much farther behind that in brainpower,” said Gill Pratt, DARPA program manager, in a statement.

From 1983 to 1993 DARPA spent over $1 billion on a program called the Strategic Computing Initiative. The agency's goal was to push the boundaries of computers, artificial intelligence, and robotics to build something that, in hindsight, looks strikingly similar to the dystopian future of the Terminator movies. They wanted to build Skynet.

Much like Ronald Reagan's Star Wars program, the idea behind Strategic Computing proved too futuristic for its time. But with the stunning advancements we're witnessing today in military AI and autonomous robots, it's worth revisiting this nearly forgotten program, and asking ourselves if we're ready for a world of hyperconnected killing machines. And perhaps a more futile question: Even if we wanted to stop it, is it too late?

Mark Gubrud has another great piece exploring the slippery slope we seem to be traveling down when it comes to autonomous weapons systems: Quote: 'Autonomous weapons are robotic systems that, once activated, can select and engage targets without further intervention by a human operator. Advances in computer technology, artificial intelligence, and robotics may lead to a vast expansion in the development and use of such weapons in the near future. Public opinion runs strongly against killer robots. But many of the same claims that propelled the Cold War are being recycled to justify the pursuit of a nascent robotic arms race. Autonomous weapons could be militarily potent and therefore pose a great threat.
