Definition of drone
The UAVs mentioned now are usually Unmanned Aerial Vehicles (UAVs), or Unmanned Aircraft Systems (UAS), without the need for a driver. An aircraft that is driven by the ground, through ground remote control or automatic driving technology, for scientific observation, battlefield detection and other tasks of the aircraft.
UAVs have military and civilian (commercial) points. In fact, the earliest drones were used for military purposes. The UAVs used by the US military during the Iraq war saw their power and were equipped with Hellfire anti-tank missiles. "Predator" and "Global Hawk" for surveillance, reconnaissance, attack and other tasks. The "predator" without sensors installed on the battlefield to act as a bait and raided Iraq's air defense system. Due to space limitations, military use is not carried out here. Interested value friends can search for "predator MQ-X" by themselves.
Project Wing delivers relief supplies, and Amazon is working on PRIMe Air for drone delivery. Domestic Taobao and JD.com also have layouts. For civilian use, it is mainly based on multi-rotor aircraft, mainly including foreign brands 3D roboTIcs, domestic famous brands DJI Dajiang and so on. For the technology of civil drones, you can refer to Vijay Kumar's speech at TED: talk flying and collaborating robots
Aerial photography and FPV
FPV (First Person View) belongs to the voyage model's over-the-horizon control, which returns the first-person perspective of the soaring sky in real time to bring an immersive driving experience. A typical FPV device consists of a camera, transmitter, receiver, and display. With the prevalence of DIY, the gap between FPV RC airplanes with automatic control systems and return transmission systems and civilian drones is also shrinking. Limited to the threshold and difficulty, no longer start DIY FPV, interested users can understand.
Aerial photography is mainly used for shooting, and the image is captured and recorded at a conventionally unachievable angle. The equipment is mainly composed of UAV + PTZ + camera. Well-known manufacturers at home and abroad have similar integrated solutions, which is mainly introduced in this article. product.

Multi-rotor drone introduction
Aerial drones mainly include helicopters, fixed wings, multi-rotors, umbrella wings, airships, etc. The civilian field is mainly multi-rotor drones, because the current technology is relatively mature, the flight is stable, can hover, and the operation is simple. Currently the most suitable choice for aerial photography. Most of the movies in the world are currently using multi-rotor drones. The shortcoming is that the short-life load is small, but in the field of civil entertainment, the problem is not big, and the maintenance cost is not high. It is mainly composed of racks, flight control, pan/tilt, wireless map transmission, ground station (mobile phone or computer) and other components.
The quadrotor is the simplest and most popular of the multi-rotors. It is called Quadrotor in English. With the popularity of the lightweight, flexible and safe Pararot AR.Drone, more and more rotor products come to us. The following is a description of the mainstream multi-rotor drone brands and fist products currently on the market.
3D roboTIcs
Brand introduction: 3D roboTIcs is a well-known open source drone brand, founded by Chris Adnerson, former editor of the connected magazine. In the field of drones, the open source project of 3D roboTIcs is similar to Android in the smartphone system.
IRIS+
Four-rotor drones with a maximum load of 400g for GoPro or other small professional shooting equipment. Flight time is around 15~22 minutes. The third-person view-and-shoot technique allows IRIS+ to automatically track the subject, and the PTZ stabilizer ensures that the subject is in the center of the frame, and can also specify routes and areas to fly automatically, such as shooting a perfect coastline.

X8+
Eight-rotor drone, compared with IRIS+, the X8+ pays more attention to the aerial photography function, and has a stronger load-bearing capacity, capable of carrying 800 grams of shooting equipment. The angle and posture of the photographic lens are automatically adjusted by the electric pan/tilt to keep the user at the center of the screen. The aluminum frame is more scalable and can be used for mapping, cloud mapping, 3D modeling and more. The X8+'s flight life is approximately 15 minutes. It is currently available for sale at $1,350.

An evacuated tube is two glass tubes, one within the other, joined at each end. The space between these tubes is evacuated so the space is under a vacuum seal. Vacuums are excellent insulators (think thermos.) The inner tube is coated with a selective coating that converts light into heat.
Guaranteed for fifteen years (the longest warranty on the market) Linuo tubes are made from high quality borosilicate glass and are fused together. This provides an all glass seal. The Linuo evacuated tube uses a unique three layer selective coating instead of the standard single al-n/al coating. It consists of an infrared emission layer, an absorption layer and an anti-reflective layer, giving a much improved performance.
