Do you want to know more things about UAVs?

With the development of Dji and X-zero, we can buy a aerial device at the price of thousand dollars which sold at least ten thousand each one. But as more and more teams enter into the market, identical function and appearance can not satisfy consumers. So the price is the major element to attract consumers.

UAV control is a technology activity. It is easily influenced by environment. Although the UAV at the mid-high level is equipped with automatic return function it still does not apply to a complex environment because of their accuracy and reaction. Moreover it is too complex for shooting when you are control ling the aircraft.

In fact, there are many areas of UAV capabilities need to be explored. Follow us GREPOW(5000mah lipo battery) to predict the new features of the UAV in the feature according to the products and technology existed.


Four axises + fixed wing aircraft = Deformable structure?


It is reported by Geeks Park a deformable UAV designed by Tesla who comes from British. The biggest bright spot of the UAV is it can meet the requirements of different shooting through its deformation. There are two different flight postures of aircrafts. When they need stability it will shoot like a "helicopter". If you need high speed with the film it will fly immediately through becoming "tiltrotor aircraft".

Similarly, in an interviewing with Geeks park a domestic professional aerial equipment manufacturing company, the company's CEO also pointed out that the four-axis aircraft flight is with few flying postures, low speed and easily to be influenced by crosswind because of the monolithic construction. But the fixed wing aircraft could remain stable under high-speed flight. If the " Variable type " is introduced to UAVs the environment of them could be expanded with increasing speed and high safety.


However, because the operator can not view flight environment in time the safety of a flying UAV is not able to be improved from the consideration of structure or even may have crashed. If you want to avoid impact of the external accidents The UAV should designed with the function of avoiding obstacles by itself.


Avoiding obstacle and following with the film


Dji has released its next-generation UAV conceptual model called Phantom X it has the functions of following with the film, controlling an array of unmanned aerial vehicles with a mobile device. If you want the UAVs to fly following with the film or do a Array flight, there must be a certain autonomous founctions as obstacle avoidance and distance detection which also can be a judgement to define the UAVs.

“So many people in the production of unmanned aerial vehicles, but do not know how to prevent these things which can lead us to fall into trouble. " said doctoral Andrew, “Laser radar mounted on drones and establish the flight path in advance is unrealistic. If we want the UAV to fly at a high speed. We need better and faster need to algorith ms." Andrew Barry team let each UAV fly 10 meters and draw the next section of the route without considerating the flying of the following 10 meters.

New Exploration of aerial mode


In addition to aerial and follower function with the film, with the development of panoramic camera and VR technology, unmanned aerial vehicles in the shooting mode will have some breakthrough.

Geeks Park, at a venture exchange, was also experienced drones racing team combined VR and UAV. Compared to ordinary racing machine, vision provided by VR is more extensive. But if you fly it at high speed it will definitely affect the bit rate of the return video thus affecting the image quality at the receiving end. If you want to solve this problem a more stable and efficient wireless communication should be established with the input device. Currently, wireless transmission scheme used by the majority of drones. It supports data transfer of 4M bps, and can be effectively against harmonic interference. But the maximum bit rate can only support 720P and can not meet the public demand.

The biggest problem is to prolong the flying time


Through a series of products’ experience and the recent exposure of a variety of news the development of the future UAV is clearly. Overall UAVs are accelerating the pace of its development in structural, technical, aerial mode and so on. But it still has a critical problem to be solved – the flying time.
Currently lithium batteries are very popular in Civil UAVs, but the small volume of a single lithium-driven UAV flight the longest flying time is no longer than half an hour. And the time would be shorter if you want to ensure the difficult shooting not to mention the cutting-edge features such as panoramic camera and following automatically .
Two aspects we need to considerate when comes to the ability of UAV to keep flying. "power" and "Battery capacity" .To reduce power consumption, it is bound to make a considerable compromise on features, configurations. If you want UAV to be able to do more things the power consumption will be increasing. The four rotors of quadcopter and aerial itself are the major parts for power consumption so UAV battery capacity has to be increased but the overall size of which in turn will affect the UAV. We can say that the UAV can not be a breakthrough if there is no a term of battery matching them.
