UAV stands for Unmanned Aerial Vehicle and it covers all remotely controlled machines that are also known as quadcopters as well as aircraft used by the US air force. These machines are mainly used by military and police officers to carry out an operation where a manned aircraft seems impractical or too risky. Unmanned aircraft are not new; they have been in use since the World War I. However at that time the control was mechanical and the aircraft could only go as far as the fuel would allow. Later on devices that could be controlled with the help of radio or infra-red technology were developed. These devices became the predecessors of the modern quadcopter that employs integrated circuit or computer chips and can be programmed to fly for a definite time period in a definite direction fulfilling a definite purpose.
If you have ever wondered what you need to get started in the RC hobby of multirotors this is the place for you. In this article I am going to outline all the basic components that are necessary to get started building your own quadcopter. First you are going to need a transmitter. The transmitter is the radio control that you use to communicate with your unmanned aerial vehicle (UAV). There are various types of transmitter that are categorized by brand frequency and number of channels. For a quadcopter you need at least a 4 channel transmitter but I would suggest getting a 6 channel transmitter that works on the 2.4GHz frequency.
There are a lot of quadcopters out there for beginners. The Smya X1 is one of the most popular. I like it because it has a 2.4GHz transmitter is very durable and very easy to fly. You can also make it do flips at the touch of a button to impress your friends. But recently I just got the Blade mQX and I must say I am quite impressed. It is actually similar in size to the Syma X1 but it boasts better performance with 4 brushed 8.5 mm motors 5.5 inch blades and a 4-in-1 receiver/ESCs/mixer/sensor that acts as flight control board. The built in DSM2 receiver is one thing I really like about the Blade mQX a lot of quadcopters come with proprietary transmitters and receivers and it can be difficult without hacking the hardware to make it compatible with your existing transmitter. With the Blade mQX you are able to bind it with any DSM2 compatible radio such as Spektrum radios.
The main function that makes these UAVs different from the ones available off-the-shelf is their ability to fly autonomously. This means that the vehicle is able to make decisions depending on its flight to change direction capture images or return to ground. These machines come equipped with various sensors and in order to make a decision the input from different sensors is merged. They are also able to communicate with other UAVs flying around as well as with ground stations and satellites. They are capable of determining the ideal course for achieving a mission. These powerful capabilities make them extremely sensitive and sophisticated devices and these operations are not available in quadcopters used for the purpose of fun and entertainment.
