Those clever programmers at the GRASP (General Robotics, Automation, Sensing and Perception) Lab at the University of Pennsylvania have made these quadrotor helicopters autonomous, teaching them how to work together while building things. Heck, most people can’t do that.

The robot builders simply tell the copters which structure to build, and then, according to a GRASP technician, the quadrotors cooperatively “figure out the assembly plan and then build it.” The flying bots even have the ability to go for another attempt if the magnetic parts don’t snap together quite right.

Even though the clever programmers have created simple modules for the helicopters to construct, nevertheless, this is the first glimpse of cooperative flying robot construction on a larger scale. Imagine if these mini copters were scaled up to 100 times their size, putting together skyscrapers, bridges, or the components of Skynet.

Experimentation with these brainy choppers has been going on for a long time. When we saw videos of the quadrotors performing autonomous feats early last year, we were immediately impressed. They were downright aggressive, flying through thin slots and moving hoops with spectacular precision. A few months later, they got even more sophisticated. Now, they’re getting downright scary.

What about it, readers? Should we be afraid yet?

Attack of the drones

Unmanned aircraft are now a vital tool in war zones, but our skies could soon be buzzing with spy planes that feed information back to the police – and even the paparazzi

There is a second-and-a-half delay between the RAF operator pressing his button and the Hellfire rocket erupting from the aircraft he is controlling, circling in the sky above Afghanistan.

That's a long time in modern warfare, but the plane is an unmanned "drone" and its two-strong crew are 8,000 miles away at Creech Air Force Base in Nevada. Right now, the Reaper is being commanded from a console with twin video screens shaped to resemble a plane's cockpit.

The UK has five Reapers like this one operating in Afghanistan. With a wingspan of 66ft, they are 36ft long, reach a top speed of 250 knots and usually carry four Hellfire rockets and two laser-guided bombs. These Unmanned Aerial Vehicles (UAVs) – which rely on fibre optic cables, European "upstations" and satellite links – are part of an international trend towards remote combat. RAF-controlled Reapers used their weapons in Afghanistan 123 times in the first 10 months of 2010.

British forces are also using smaller drones, such as Lockheed Martin's hand-launched Desert Hawk. The lightweight surveillance aircraft is flown by Royal Artillery controllers to provide army patrols with "over the hill" vision for improved reconaissance. Last summer the Ministry of Defence ordered £3m worth of an enhanced version that will give troops in Afghanistan "greater situational awareness" and upgraded "target acquisition" capabilities. On the US side, there were more than 100 CIA-led drone strikes in Pakistan last year and the Pentagon is about to deploy its intimidatingly named Gorgon Stare airborne surveillance system, a multi-image video device for tracking suspects across large areas.

But interest in UAVs is not limited to the military. Advances in remote control, digital imagery and miniaturised circuitry mean the skies might one day be full of commercial and security drones.

They're already being used by the UK police, with microdrones deployed to monitor the V festival in Staffordshire in 2007. Fire brigades send similar machines to hover above major blazes, feeding images back to their control rooms. And civilian spin-offs include cheaper aerial photography, airborne border patrols and safety inspections of high-rise buildings.

Despite this development, not everyone, even within the miltary, thinks that drones will eventually replace all other planes. Wing Commander Christopher Thirtle is responsible for the RAF's strategy on remotely piloted air systems (RPAS) — the term preferred in air force circles.

"Reapers will not replace Tornados. Human beings bring flexibility like no computers," he told an audience at the Royal Society in London.

It may be just as well: there has been international criticism because a significant number of those killed in drone attacks have been reported to be innocent tribesmen misidentified as al-Qaida leaders, or villagers caught up in targeted explosions.

But Thirtle insists the RAF is bound by international laws governing armed conflict – specifically the principle of attacks being discriminate and proportionate. "We have a targeting directive which sets down who are combatants and sets out rules on how we can engage [them]."

A ground pilot's extreme distance does not necessarily result in greater collateral damage, he argues. Aircrews in Kosovo conducted bombardments from 22,000ft. "If I was asked where I make the best decisions about people on the ground, then my clarity of thought is much more conducive at a ground control station [without] a 10lb flying helmet on my head."

Accustomed to the 20th-century gadgetry of cruise missiles, CCTV, satellite phones and radio-controlled model aeroplanes, technical experts and peace campaigners have only belatedly become alarmed by the combination of such capabilities.

The International Committee for Robot Arms Control (Icrac), founded in Britain in 2009, marked the beginning of a global – if small-scale – protest movement. The organisation held its first workshop in Berlin last summer and called for a ban on the "further development of armed autonomous robots", limits on numbers operated by any state and restrictions on the use of armed drones for "targeted killings in sovereign territories not at war".

Even the UN human rights special rapporteur, Philip Alston, has warned that US drone killings may violate international law. He has called on the US to explain the legal basis for its attacks. Others have taken direct action: peace protesters recently breached the gates of the Creech base – 14 of them were arrested for invading the site. Kathy Kelly, their spokeswoman, said: "We protested because . . . the US is, at an alarming rate, moving into robotic warfare, kind of a mission creep, that could lead us into perpetual war."

Opponents of drones fear they will lower the threshold for wars to start in places such as Yemen and Somalia, where the US is not involved in any formal conflict. Yemen was the site of one of the earliest CIA-co-ordinated Predator drone attacks on al-Qaida targets as early as 2002. There have been further drone strikes there since the failed Christmas Day attack on a transatlantic airliner. A fresh onslaught, it is suspected, is being planned in the wake of the recent Yemeni-based plot to destroy cargo planes.

Noel Sharkey, professor of robotics and artificial intelligence at Sheffield University, told the Royal Society meeting there are credible estimates that one in three casualties from drone attacks is a civilian. His chief anxiety is the development of "autonomous targeting", where unmanned planes are engineered to lock automatically onto what their onboard computers identify as the enemy. The military are keen on this because it would no longer have to worry about radio signals being jammed.

"There's a really big drive to get autonomy," he says. Manufacturers are even working on "swarms" of vehicles that can co-operate. "The big problem is there's no system capable of consistently distinguishing [between] targets. The Pentagon is funding research labs and saying these things can 'think': that's strong anthropomorphic language."

However, Thirtle is adamant we will never reach a Terminator-style situation where robots run out of control. "There will be an enduring need for a man in the [control] loop for the foreseeable future," he maintains.

The Oxford-based Fellowship of Reconciliation is "seriously concerned" the UK might be sanctioning a culture of "convenient killing . . . Our core concern is with 'PlayStation warfare', where the geographical and psychological distance between operator and target lowers the threshold for launching an attack."

Thirtle dismisses the accusation. "The people doing this are adults," he said. "They understand flying and the effects they are having on the ground. They are not remote. One pilot told me he had never felt more connected to the ground than in flying a Reaper."

But Steve Graham, professor of cities and society at Newcastle University, who studies urban battle grounds, warns that the US military's "technophilia" and "fantasies of omnipotence" blur the distinction between surveillance and killing. As he puts it in his book Cities Under Siege: "The possibility of deploying swarms of armed and unarmed robots to loiter persistently across regions of the world deemed trouble spots is clearly a good fit with the Pentagon's latest thinking surrounding the long war."

The growing popularity of UAVs can also be witnessed in the UK's congested skies. The Civil Aviation Authority (CAA) has conducted two safety inquiries, the first of their kind involving UAVs, into the use of drones over Salisbury Plain following reports of near-collisions with helicopters. (It concluded that the ground operator avoided a risk of collision.)

Border patrols present a further opportunity for deployment. The US Customs and Border Protection Agency has announced that it is patrolling all 2,000 miles of the Mexican border with Predator drones equipped with night vision cameras. Frontex, the European border agency, has held a drone demonstration conference in Bulgaria, while the UK Border Agency says: "[We] do not rule out the use of drones in the future if they can be shown to provide a value for money increase in our border security."

At least four police forces – Essex, Merseyside, Staffordshire and the British Transport police – have bought or used microdrones. Last summer the Serious Organised Crime Agency published a tender notice requesting information on "a fully serviced, airborne, surveillance-ready platform for covert observation" provided by either drones or manned aircraft. And several fire brigades – including West Midlands and South Wales – regularly send up drones to check on the spread of blazes.

Commercial distributors and manufacturers are convinced drones will gradually displace expensive manned aircraft and expand into even more areas. Aviation experts already envisage a time when unmanned cargo planes, fitted with collision-avoidance detectors, circle the world.

Given this progress, it cannot be long before news organisations exploit microdrones to obtain picture exclusives: imagine aerial races between Hello! and OK! magazines. Last autumn a US academic claimed he was developing a "paparazzi drone". Ken Rinaldo of Ohio State University said it would have a lot of "flash and bling".

"UAVs will, to an extent, replace helicopters," believes Mark Lawrence, director of Air Robot UK. "Our 'air robots' cost £30,000 compared with £10m for a fully equipped modern helicopter. We have even been asked to put weapons on them, but I'm not interested in getting involved in that."

Alistair Fox, commerical director of Air Power Systems, which supplies microdrones to the fire service and the government's Health and Safety Laboratory, claims drones have "all sorts of commercial applications for safety inspections. With thermal imaging and air-sampling devices they could check for cannabis being grown under lamps in roof lofts." Another suggested use is perimeter patrols around prisons.

There are possible uses – drones have already been used for high-altitude research into hurricanes. And Israel lent the Chilean airforce several to inspect damage after the country's earthquake this spring. In Japan, drones are used to cropdust rice fields.

Many of the 70 permissions already granted by the CAA for drones to fly in UK airspace this year are thought to relate to civil engineering surveys or aerial photography companies. But the agency has warned: "In the wrong hands or used irresponsibly in built-up areas, or too close to other people or property, [drones] represent a very real safety risk."

The advent of effective "sense and avoid" systems would transform the technology, the CAA admits, opening up a future where unmanned UAVs could float safely above our heads. The first firm to design an acceptable system could make a fortune.

Part of the CAA's anxiety was due to postings on YouTube showing near–collisons in central London involving microdrones launched for amusement. Some of the latest models can be controlled by iPhones. Permission is now required to fly a drone "within 50 metres of a person, vehicle, vessel or structure" not under the control of the remote operator.

Even without these restrictions, it may be a while before our streets echo to the buzz of unmanned aircraft. John Moreland, general secretary of the Unmanned Aerial Vehicle Systems Association, the trade body that represents the industry in the UK, suspects that security surveillance at the 2012 Olympics will be conducted from an airship rather than highly mobile drones.

The CAA, he says, is unlikely to allow UAVs to operate so close to large crowds because of "reliability" issues. The east London site, he also points out, is too close to London City Airport.

One airshow enthusiast has nonetheless contacted the Guardian to say he is convinced he spotted a drone passing over the Olympic site. "Its length was about 8ft and its altitude between 300ft and 400ft," he said.

The authorities denied any knowledge of the flight. "The public perception of drones at the moment is that they are a little bit sinister," Moreland adds, "but the technology is becoming more widespread and there are lots of applications. Everyone is feeling their way forward."

RC Controlled AR.Drone with #Arduino UNO and #WiShield

One of the biggest limitations of the AR Drone is its WiFi 802.11b signal range.  Mheeli over at RCgroups.com has worked up a solution that bypasses the whole WiFi need completely and instead uses an RC Controller.  If your looking to mod your AR drone this will require some soldering knowledge as well as some light programming skills.  Check out his video below and if interested, his tutorial.  You can order all your parts from me here

Parrots AR.Pursuit #augmented reality shooter #app for AR.Drone now available on #iTunes

Parrot has just released AR.Pursuit which is the Augmented Reality shooter of its previously released app Free Flight.  They also have a video which is inline with the others they have produced unfortunately it does not show what happens when the Drone is shot or if there is feedback on the iPhone for the one piloting when the Drone is hit.  Either way, I look forward to seeing how it behaves with my drone and lighting mods made to the hull.

AR.Pursuit pinpoints the outstanding technical and flight capabilities of the AR.Drone, allowing the players to put their piloting skills to the test. This game demonstrates the extreme maneuverability and stability of the AR.Drone. Players are immerged in a world where real and virtual mix inside a pursuit race…a truly unique experience!  [iTunes]

Player one, the hunter, pursues player two, attempting to bring him down with virtual missiles. Once caught, the players change roles and a new pursuit begins!  [iTunes]

Here's how it works: the game uses the Drone's front-facing cameras and renders in bullets and missiles when players choose to fire. To avoid game-death, players will need to maneuver their drones in various directions, hiding and assaulting their opponent as needed.

The game, which retails for $2.99, can be played indoors and outside, provided a stable Wi-Fi connection can be accessed. Parrot recommends that you use those indoor stickers if you plan to play indoors, and obviously you'll want to pick a place that's large enough to move a radio-controlled craft around in. [Mac|Life]  > My recommendation is an empty underground parking garage or an abandoned nuclear silo.

How to find the best time to fly the Parrot AR Drone outdoors

I love my AR Drone but flying it outdoors can be a significant challenge especially if you live in a area where the weather changes frequently.  Wind and rain are naturally the biggest threat to your drones electronics, battery life and your sanity.  There are a several apps available in the iTunes store that help you forecast the weather in your favorite areas to fly.  

Here are a few I use to determine the best time of day to fly all of which are available in the Apple iTunes App store.

AR Drone Mods: Ball-bearing Replacement for Stock Rotor Bushings

AR Drone enthusiast are replacing the stock brass bushings for friction free ball bearings. You can order yours here

For those looking for a how-to or step-by-step guide, check out Zenocha’s guide

I did notice any increase in performance and the motors do seem to run cooler. This of course has not been confirmed with any actual readings and my ability to determine temp diffs with my fingers. I plan on replacing the bushings on the front two rotors opposed the back and determine a difference in temp between them. Test results to follow.
