Metrology: How does a drone work? MEMS sensors: accelerometer, gyroscope. Principle of operation.

Metrology: How does a drone work? What is its operating principle? What role do MEMS sensors such as accelerometer, gyroscope or magnetometer play in a drone? What is the drone control algorithm? What measurements does a drone perform during flight? I answer these and other questions in this video. Best regards, Piotr Burnos.
