Review of a kvadrokopter of Parrot AR.Drone 2.0: flight without compromises
In 2010 there was a real boom of radio-controlled toys, and and is concrete, flying. The Parrot company presented AR.Drone. On CES 2011 the device appeared is recognized as one of the best entertaining gadgets, the public was in ecstasy. As showed experiment of use of AR.Drone, the people not for nothing — this categorical entertainment for «adult children» admired. But on reached magicians from Parrot not тормознули. At the international exhibition of consumer CES 2012 electronics the history repeated already with AR.Drone 2.0: ecstasy of guests, a storm of the emotions, shivering voices, interrogative — WHEN? When this miracle will get to sale? Already got and it is ready to deliver the pleasure sea. But after all it is interesting to learn, and what such new in AR.Drone 2.0, for what it is necessary to overpay and there is it that? Let’s understand together.
A little uglovaty
Outside the novelty not especially differs from the predecessor, the main configurations inside though Parrot worked and over a case design. And it is concrete, judging by the statement of the producer, AR.Drone 2.0 became stronger than own predecessor. In a kvadrokopter are at present used easy, but very strong карбон though from it only some details of which the overestimated loading is the share are executed. Plastic (PA66, it is used when developing a car of bumpers) is reinforced by carbon fiber that also increases a design krepkost as a whole.
The set of delivery did not exchange, and it is possible to find the following in a box: a kvadrokopter, the demountable accumulator on 1000 мАч, the charger with several forks adapters (the European is available), the thick summary (Russian is not present) a sticker on the case and, nearly, pair of cases for flight in rooms and outside where winds blow wild, and monsters wander strshny … a joke. The "street" case a little exchanged in a form, in comparison with such at AR.Drone of the first generation. It became slightly uglovaty that in particular is appreciable from the chamber, and a little narrower.
The protective casing for flights in rooms possesses the same features: slightly more flat cabin and a little uglovaty form, but as a whole the same. As the main material something is used similar to polyfoam, only is stronger, than packing, but at all this and is slightly softer. On the last measure, it belongs to arches protecting blade. They rather rigid very not to cave in at blow about a wall or though what other obstacle and not to damage the blade, but at all this it is excellent демпфируют such influence.
Though, nothing prevents to use this case and in the open air as AR.Drone 2.0 began to keep much more measuredly in air and is capable to resist simply to flaws and other natural phenomena, for what very zamaterevshy interior bears responsibility.
Skyscrapers to us not a hindrance with such protection …
… and mountains too

At the moment of own release in 2011 unique AR.Drone seemed a summit of the desires in comparison with traditional radio-controlled flying toys: two chambers (a VGA sensor and 176х144 points), the trekhosny accelerometer, pair of gyroscopes, the 468-megahertz ARM9 processor, 128 MB of RAM (DDR of 400 MHz), the Wi-fi module and even an operating system on the basis of Linux, also ON with an open initial code which can be updated and modified. But after all now in all HD era storms, and logical would be to equip with the corresponding chamber the newest model of a kvadrokopter, as was made in AR.Drone 2.0.
Yes, the device is capable to shoot video in permission 720p and with frequency of 30 frames per second though this modernization pulled along also other new things, and is direct, more powerful ARM Cortex-A8 processor with frequency of 1 GHz (same it is used in SoC Apple A4, and it is established in iPhone 4 and in iPad of the first generation), the separate 800-megahertz DSP processor for processing of a video stream (TMS320DMC64x), 128 MB of an operativka of DDR2 (is twice more productive, than in the predecessor), USB 2.0 port for connection of the periphery and the flash – is driving (USB 1.1 in AR.Drone), plus some more a component about which we will have a talk below.
Naturally, not all mentioned innovations are necessary for HD video realization. By the way, the content is broadcast directly in phone or remains on the attached flash drive, for economy of a disk place on iPhone. In the first case of video at desire it is possible for a meeting to send on YouTube directly from the managing director of a kvadrokopter ON, it too was seriously updated.
As to the characteristic written down through a wide-angle lens (92 °) video though permission and HD, but extent of compression it is very high, is lost specification in flowers, well and the balance of the white is defined not so precisely, the picture often has a pink shade. After all, will remove AR.Drone 2.0 better than the predecessor.
And here that at a novelty really very much exchanged in a positive side so it is maneuverability and, as result, maneuverability. It became much simpler to use a toy, at present children of years will cope with it from 7 even and is more senior. How magicians from Parrot of it achieved? Simply! The whole matter is in much increased quantity and the overestimated quality of sensors for which more powerful processor was required, after all given at present to process to it it is necessary much more.
And it is concrete, to the trekhosny accelerometer the real trekhosny gyroscope (an angle of rotation — to 2000 degrees/seconds), plus still the trekhosny magnetometer (accuracy — to 6 °) and even the barometric sensor was added. Pair of ultrasonic sensors very precisely calculate height of flight of a kvadrokopter (to 6 meters). the 2nd chamber located on the bottom (QVGA, 60fps), defines speed of flight of the device. Pair of green light-emitting diodes shows, where at the car a forward part, pair of red — back. As usual, instead of reading a hundred part of clever words, it is better to behold once that all this "elektronshchina" gives:
Pay attention, how the kvadrokopter, not to mention it кульбитах in air correctly moves.
It should be noted that responsible for accessory movement the interior too exchanged. In AR.Drone 2.0 four besshchetochny motors in capacity 14,5 Watt and with speed of rotation of 28500 rpm (15 Watt and 35 thousand rpm at the predecessor) are established. The capacity and speed of rotation of propellers a little decreased, but time of independent work from the standard accumulator from 12 to 16 minutes increased. Well and such change was not reflected in flight qualities. And thanks to Nylatron gear wheels noise when flying considerably decreased.
The design of a kvadrokopter such that all electronic interior is very protected from blows and other incidents, for example, from water. Not including that parts sensitive to blows are placed in the special foam extinguishing vibration and pushes, electronic components are covered with water-repellent structure. AR.Drone 2.0 without troubles flies in the rain (speech, naturally, not about heavy rain), at all this without negative consequences for itself. And at collision though what propeller with an obstacle the machine gun disconnects all four in order to avoid their damage.
The mass of the device remained invariable: 380 g with a casing for street flights, 420 g with the case for use in rooms.
To new kvadrokopter the new software, at all this is a question not simply of planned updating of the standard utility of FreeFlight [Free, iTunes link], and about true updating of the program. In fact, in the version 2.х it is absolutely new product to the maximum using possibilities of AR.Drone 2.0.
Society round AR.Drone exists for a long time, but in FreeFlight 2 it actually was legalizirovano in "AR.Drone Academy" section. But it is only one innovation from many, including network.
For example, the finished shooting media content can be loaded into the Network directly from the appendix, and it is direct, photos download in a web album Picasa, and video — in YouTube. Not including that, right there, in the program menu, extraneous appendices are available to a kvadrokopter, allowing to connect the world real and virtual in games on the basis of the added reality and even to arrange joint entertainments.
There were also new functions of piloting though the interface of the DU virtual panel not especially exchanged:
As to piloting options, thanks to additional sensors it is possible to set a limit of height of the flight, the highest speed of rotation and lifting, a bigger tilt angle:
But it is more important, naturally flight, instead of all these ruches and gadgets. And with flight at AR.Drone 2.0 everything is excellent. The Parrot company could make one of the most advanced and simply operated flying toys in a past, and in real it simply surpassed herself. Thanks to the magnetometer built in in a kvadrokopter, it is possible to operate very precisely the device, actually sending its chamber to the suitable party. A sudden wind or a rain — it doesn’t matter, the clever interior compensates hindrances, and the device will obey the user as it is correct, as well as in clear windless day.
While the device new and, naturally, it is necessary to use it accurately. For example, in it there is a mode of a crash landing, but at one zabugorny colleagues at its activation motors of a kvadrokopter were simply disconnected and it fell down from height of several meters the earth, having damaged one screw. It doesn’t matter, naturally, not essentially what part of an acces
sory changes in house aspects and all accessories are available, but, after all, this superfluous time and expenses. After all, ON it is modernized and finished, the found mistakes quickly are eliminated.
Besides, the device became really stronger. As shows experiment, it it is simple and without consequences transfers small blows and falling from height of human growth, in particular if the protective casing is used. But it is better than such moments to avoid.
Expensively and angry
Parrot AR.Drone 2.0 is more expensive of the predecessor. In the Russian realities the price of the device is in borders of $650-700 and the difference with the original reaches $200. And whether there is a sense to overpay?
My personal outlook — yes, sense is. In fact, AR.Drone 2.0 — it not simply updating of a popular toy. It is absolutely new accessory with completely processed interior. It is better operated, it is stronger, at it the chamber is better, well and society will quickly be switched to a novelty because of its more ample opportunities.
It still a toy for «big children» owing to its price and specifics though as I mentioned before, under the supervision of adults children will simply cope with management of a kvadrokopter which is capable to deliver many pleasant minutes during house rest and walks. But "heat", naturally, begins when the owner remains with AR.Drone 2.0 in private. The main thing to be reserved by pair three of additional batteries — and in fight!
