The drones are in the ‘mouth of the populace’. Robots flying became subject that arouses curiosity and his deeds made them popular. But have you ever stopped to think what they are, exactly, the drones? How do they work? To end these questions the TechTudo prepared a special text that explains the scenes of this technology.

What are drones?
These popular robots are small flying vehicles remotely controlled by an operator. For the magic happen since they use simpler controls, which can be handled on the screen of a smartphone, the more complex commands, which require radio remote control itself.
As they Work?
Even the most current drones, focused on domestic consumer, is a very small and extremely lightweight vehicle.
Normally they are carbon fiber composites, very little metal and plastic materials. The fiber gives strength and lightness, while the plastic is used in the structure points that are not crucial to the device resistance. The metal is on the screws, the battery and the motor.
There are several drones settings, but the most common are those that use four motors located in a four-axle ends. These small engines are electric and turn small propellers that support the device of flight, adopting the same principle that explains how helicopters fly.
In the main body of the drone you find the batteries, by weight matters tend to be very small. So even the best in the market usually have drones flying range of a few minutes.
In the phone fuselage is also a logical board that contains the navigation and control systems. In this circuit, depending on the device, there are GPS chip, which allows precise navigation and more free flight. Using satellite location positions, you can trace a path previously and drop the drone will follow to the letter the path drawn by the controller.
On the same card there is a computer that receives the navigation instructions in case of manual control and transmits to the engine, increasing or decreasing the acceleration and altitude. Depending on the device, no data transmission resources for the controller, ranging from amount of power left in the battery to images taken with a built-in camera.
Many drones also carry cameras. Some of them even use high quality cameras, able to record images in 4K. The drone niche market for video and photo recording grows enough: before, who needed to capture aerial images depended on the rental of a helicopter, something expensive and inaccessible to many people
There is. course, more complex drones and fleeing this standard model. The military drones (much larger, some with combustion engines) are a good example. Similarly there are smaller versions, easier to use and to maintain, aimed at those who want to learn to control a drone without risking a very high investment.
Drones have artificial intelligence ?
Most of them do not. Passively, they obey commands from an operator on the ground, transmitted via radio from a remote potent. You can understand them as passive robotic tools. But for more complex products, that have some level of autonomy and flight control, especially the models that are able to navigate via GPS alone.

Applications and uses in the future
Currently, drones produced for the domestic consumer are very focused on image registration. But there are many people working on developing technologies and services that may use drones to delivering products in urban environments. The Amazon , for example, recently obtained authorization to test the service in the US. The Google also flirts with the idea of having their products delivered to consumers by flying robots.
Another focus of developing technical institutions and manufacturers have been creating increasingly autonomous devices (not only towards greater flight duration, but capable of flying more independently) for use in risk situations and rescue considered inhospitable or inaccessible to humans environments.
