Chapter 486: Where is the big pigeon
The Egret is also a bee drone, but in the fixed-wing series.
Because of the principle of lift and battery technology, it is difficult for the endurance time of the four-axis to exceed half an hour, so after the bee has a certain amount of technical accumulation, it has also begun to try other forms of models, including the traditional fixed-wing, as well as the more novel flapping wing, but there is no rotary-wing model similar to the helicopter, because it is not a good carrier platform because it shakes too much.
Multicopters such as quadcopters rely directly on the downward blowing propeller for lift and the speed difference between adjacent propellers for horizontal maneuverability, which has the advantage of not requiring much aerodynamic knowledge. A simple four-axle is not much more complicated than a four-wheel drive, and many college students with a basic foundation can make it by themselves.
With universal boards like Raspberry Pi and Cookie Cards, it's even easier to make. In particular, Bee not only launched the flight control program and other related software for the cookie card, but also prepared a complete set of spare parts and accessories very considerately. Users can directly choose and buy the package, then download the relevant software, and then give full play to their hands-on ability, they can easily assemble their own DIY drone. It's very simple and crude, and the price is very cheap, especially if you have a ready-made cookie card and a mobile phone, buying the cheapest set is less than a hundred yuan, which kills a batch of low-end entry-level models.
Of course, even if the things that come out of this can go to the sky, they are just toys for enthusiasts to entertain themselves, and the technical parameters will be able to be used, after all, this kind of "biscuit drone" is only less than two hundred pieces at a minimum, and it really can't ask too much for performance.
In fact, it is still difficult to build an excellent drone, on the one hand, it requires a series of software and hardware technologies, such as video wireless transmission, anti-shake technology, positioning and navigation, obstacle recognition and other technologies. On the other hand, as an aircraft, a lighter body, better power and energy sources, more efficient propellers, and a lower drag form factor are also necessary for the pursuit of excellence.
Computer hardware and software are considered to be Atletico Madrid's advantageous projects, whether it is self-research or cracked after copycat micro-innovation, E7U can help him save a lot of time and costs. However, in the fields of mechanical engineering, aerodynamic design, and materials and components, Atletico and Bees have no shortcuts, and can only slowly throw money at it. Affected by Atletico Madrid, bees lack the craftsmanship to pursue the ultimate, which also leads to the fact that bees have always lagged behind in cutting-edge products.
But even so, because of the relatively small UAV market, 60,000 units last year were enough to send them to the second place in the world in civilian UAV sales.
In fact, if you only count the number of shelves sold, it is okay to remove the word civilian. After all, even if the sales of military drones have increased rapidly in recent years, because they are too expensive, the annual sales have not exceeded 2,000 units.
However, this basically does not make much sense, and the most sold drones on the market are all consumer-grade products that cost hundreds of thousands of dollars or even tens of dollars. If you compare sales, a single "Global Eagle" can be silent.
Civilian products are usually divided into consumer grade for ordinary consumers and commercial grade for commercial scenarios according to different users, although commercial UAVs have a price of tens of thousands of dollars because the carrying system is more professional and expensive, but the sales volume is much less.
In fact, military drones can also be regarded as special commercial products, but they are more demanding, more expensive, and have various purchase restrictions......
You must know that the world-famous "Global Eagle" of Eagle Sauce is the latest cost of 130 million US dollars alone, and you have to add another 100 million to the price of research and development expenses, and this is still the internal purchase price of Meijing, and it is more expensive to sell allies. In 05, Nan Kimchi planned to buy four planes to peep at the second fat next door, but the Eagle Sauce Congress dragged on for 8 years to get approval, and at this time, the price of the "Global Eagle X4 Korean Deluxe Set" rose to 1.2 billion, and the universe felt all kinds of pain in a dilemma.
Even so, the seller NG company (Northrop Grumman) still likes to ignore it, saying that there is spot wood, early payment, early construction, early delivery, and the estimated delivery time is 2017......
Compared with the kimchi family, Hans Meow's family is even more miserable, Meow once tried it when he beat the stupid big wood with the boss Eagle Sauce, and it felt great, so he had the idea of borrowing the "eagle" to lay eggs. At that time, the plan was to cooperate with Europe and the United States to establish a new European Eagle company, use the American version of the fuselage with the European version of the reconnaissance system to produce the so-called "European Eagle", and planned to sell it to European partners. As a result, Meow-chan fell into the pit all of a sudden, and the Eurohawk was a new aircraft and needed to reapply for relevant license documents, but because it was not equipped with an on-board system to avoid collisions, it could not obtain EU flight clearance and was banned from flying over Europe. Seeing that the follow-up R&D investment would cost hundreds of millions of euros, Hans Meow had to reluctantly suspend the project, which is equivalent to saying that they spent nearly 700 million euros and about 1 billion US dollars in advance, and finally only got a technical verification version of the Eurohawk, which can be regarded as the existence of the most expensive in the UAV.
After all, the Global Hawk is a large UAV, with a maximum take-off weight of more than 10 tons and a maximum range of 26,000 kilometers.
Although Bee is also a small kick in the field of military UAVs, the so-called Iron Bird has been launched, but the latter is only a low-cost small individual reconnaissance aircraft, and Bee has not actually produced this model, and the full set of technology was sold after the development was finalized, anyway, their real purpose is to sell the supporting video recognition system. The unit price of the latter is much higher, and it is also the "traditional" advantage project of bees, and the strength is a big cut off other competitors, and all bees need to do is just go through one field at a time. Where these iron birds and the supporting identification system were later used, and what they were changed into by magic, even Atletico Madrid didn't know very well, let alone Shen Mo and Wu Pan, ordinary fans like them.
However, they know the name of the Iron Bird's civilian version of the relative, "Big Pigeon". On the way home, Shen Mo also complained to Sun Yan next to him, saying, "The bees are too picky, since you want to take the drone as a prize, why don't you take out the big pigeon." How handsome the big pigeon is!"
"What are you looking for Brother An, be careful that she cuts you!"
"How could it be, don't dare, don't dare!" Shen Mo said busily.
As a peripheral member who has been active in the house dance industry for a long time, he, like Sun Xiang, has heard of the name of the famous soul singer in the cover industry, and he will also hum a few words "The fireball of the fire method that loves to play with fire".
"I'm talking about the big pigeon drone. Shen Mo patted the big box he was holding in his arms, which was the prize that Sun Yan had drawn, "It's a winged drone like this egret, but the egret is a fixed-wing rear propeller, and the big pigeon is an ornithopter." ”
"That's right. But the name bee is too cheap, isn't it?" the girl chimed in.
"Fortunately, the shape of the big pigeon is indeed a larger pigeon, and ordinary people can't really tell the real from the fake if they don't pay attention. ”
"If you pay attention, you can still tell the real from the fake?"
"It's natural, no matter how flexible and small the artificial muscles of bees are, they can't compare to real muscles. So if you look closely, you will still find that the flight action is very stiff. ”
Sun Yan didn't know much about drones, only knew that they could be used for aerial photography, so he poked the head of the drone on the box and asked, "What kind of big pigeon can be used for aerial photography?"
"Uh......" Shen Mo hesitated for a moment, and finally chose to tell the truth under the silent gaze of the female ticket: "There is indeed a camera in the eyes of the big pigeon, but the resolution is not high and it is trembling, basically it is like a product." ”
"Ah, why are you pinching me!"
Hearing the noise behind him, the driver in the front seat shook his head calmly and gently, thinking, "Young people now......!
……
A day later, on the edge of the park square, a strange plane with gray body and white wings sits on a flower bed with imitation marble tiles.
The round and slender fuselage, the straight and narrow wings with the long and upturned ends, the propellers mounted on the tail, the four or three tail fins that wrap the propellers in an inverted Y-shape, and the nose camera that looks like a rubber head make this Egret drone very recognizable.
After getting this drone yesterday, Shen Mo was already studying this guy.
Although as a fixed-wing aircraft, the operation of the Egret is more troublesome than the quadroter, but it is only the take-off and landing stage that needs site support, and the inability to hover in the air, these two points are more troublesome, and other places are exactly the same as the quadroider, and all kinds of necessary functions are readily available.
Because of the relationship between playing with biscuit drones, Shen Mo originally had the drone remote control application "Bee Pilot" on his mobile phone, and he quickly got started after completing the pairing. Today, when the supporting batteries are fully charged, he pulled Sun Yan out to fly a kite, no, it was to fly a drone.
Shen Mo was holding a white object like an insect's head in his hand, which was the remote control of the egret, and the two slender silver "tentacles" were naturally the antennas. The egret can be remotely controlled directly through the mobile phone or even the bee bracelet like other bee drones, but the effective distance of the latter two is very short, the mobile phone is less than 100 meters, the bracelet is less than 10 meters, and the flight speed and flight radius of the egret are much larger, so this special remote control with its own battery and antenna is a must.
The bee that slammed the door did not equip the remote control with a screen module, there was only a clip where you could fix your phone or a small tablet and connect it via WiFi. If you don't need the real-time video transmission function, you can also use the remote control directly without your mobile phone and operate it visually.
It's just that in this way, there is not much difference between the use and the ordinary remote control model airplane, and the value of the image transmission system cannot be brought into play at all.
So Shen Mo also brought a 7-inch tablet computer before coming out of the house, this kind of Android version is now getting cheaper and cheaper, and it has broken through the 500 mark downward, and there are even two or three hundred, this board is Shen Dad on the road to participate in the merchant's "full 300 free tablet" activity "free gift", the configuration of natural scum is not good, the running memory is only 256 megabytes, basically it can't be used. Shen Mo brushed it with the "baby elephant pados" produced by bees, which was barely usable.
The little elephant is actually a low-profile version of the elephant OS, so it is still a modified version of the Android system, and Bee specially pre-installed a special little elephant app store for it.
Many people know that Android phones have a curse-like feature: "they will become stuck in half a year". Of course, there are reasons why the system has been running for a long time and accumulating junk files that slow down the speed, but the real reason is actually in the Android app itself.
Although the application update description usually has the saying of "fixing bugs, improving stability, and enhancing performance", in fact, under certain hardware conditions, the new version of the application is usually more card than the old version, because the hardware resource overhead of the new version is generally greater, after all, there are more functions, and the configuration of mainstream devices on the market will also be significantly improved when the new version is launched.
Therefore, the so-called "low-profile version of Android", the core point is to prepare a "backward version, see the good one" app store for backward devices, although this will lead to some new features of the application can not be used, but it is better than not being able to use it at all.
And there are some careful thoughts about the old one's self-interest, the code automatically generated by the bee BC programming platform, although it is not "God optimization", but it is also the mainstream level, mature and stable with few bugs, so it is naturally more friendly to low-end devices. Specializing in a low-end version of the elephant system, the purpose is obviously to further play this advantage, "other people's old software" vs "the latest version of bee software", it is natural for users to choose at a glance.
Although the sales volume of bee drones is not much, and there are only more than 100,000 users around the world, Bee still launched a multi-language and multi-platform "Bee Pilot" application for them, which is one of the reasons why bee drones can occupy half of the country in China, although there are only more than 10,000 people in this half of the country.
The operation of this app is very foolish, users can not only point to the country on the map interface to draw the flight trajectory, but also can play the air combat game in real time, all the operation steps are simple and clear, even Sun Xiang after half an hour of familiarization, can also be smoothly started.
To outsiders, the white model plane in the sky flew unusually ugly, turning half a circle to the left, half a circle to the right, and from time to time it had to turn several times in a row like a headless fly, as if it was looking for something......
It's really looking for something, the egret can't hover, and it will hover without follow-up orders, but the two are not very proficient in real-time mode, and the result is the above scene. For mobile phone users, please visit http://m.piaotian.net
