Inside the Drone

The four motors placed at the ends of the arms allow to maintain a decent stability. The motors of a drone are also called Brusheless or "brush", their high frequency allows in a unit of time a sufficient number of revolutions to generate a reaction force then pushing upwards.

Each engine has an ESC. An ESC is an electronic circuit whose purpose is to vary the speed and direction of rotation of a motor. In my case I used 30 Ampere ESC.

To work, a drone must have a flight control unit. The flight control unit can be imagined as the control center from which, after receiving external stimuli (via sensors), all commands are given. Barometer, magnetometer, accelerometer and gyroscope are the essential sensors to ensure the proper functioning of a drone. Generally all flight control units have these instruments. The drone is equipped with the Crius SE v2.5 control unit.

The last fundamental part of a drone is the remote control. The remote control (used on the ground) sends radio signals to the receiver (mounted in the drone) which in turn is connected to the flight control unit.

The drone was programmed on Arduino. The code, having a decidedly high complexity, can be found without much effort among the resources in the intenet.
