We haven't even had time to study the quad-rotor drone, and it has quickly become a hot product. Compared with fixed-wing four-rotor UAVs, multi-rotor aircraft are more stable in flight and can hover in the air.
The brain of the four-rotor drone flight control: microcontroller. It is on the flight control motherboard of the quadcopter and does not require many chips.
The current toy aircraft simply fly or stay in the air. As long as it can receive instructions from the remote control and control four motors to drive the propellers, it can basically achieve the function of flying or hovering. The main components of the quadrotor ESC UAV include flight control and remote control.
The multi-axis aircraft is composed of different modules such as remote control, flight control, and power system. According to the needs of different grades of products, different CPU cores will be used.
For example, the flight master control function of a quadrotor UAV is simple and small, and it must integrate remote control reception, flight control and power driving functions at the same time. The mid-to-high-end multi-axis aircraft uses built-in DSP and floating-point arithmetic units, which are responsible for the main flight control function.
