Pro tebe a další trouby, co nevědí, jaký je v tom rozdíl.“Drone” is a broad term used to describe any kind of unmanned aerial vehicle (UAV). As such, it can be used to describe both UAVs that are remotely controlled and those that are controlled by onboard computers. These types of aerial craft can look either like a small airplane or like a helicopter. They generally have two characteristics that set them apart as drones: They are engine-controlled, and they can fly for long periods of time.“Quadcopter” is a more specific term used to refer to a drone that is controlled by four rotors. It is also called a quadrotor or a quadrotor helicopter. The rotors on the quadcopter each consist of a motor and a propeller. In addition, these UAVs are always controlled remotely instead of being controlled by a pre-programmed, onboard computer. Quadcopters resemble helicopters, but balance themselves by the movement of the blades and not by the use of a tail rotor.In view of these definitions, it is accurate to think of drones as a broad category and quadcopters as a specific type of drone within that category. There are many other types of UAVs (such as tricopters, hexacopters, and octocopters) that also fit the general description of a drone. A drone can only be considered a quadcopter, however, if it has four rotors.
