The invention provides a coaxial dual-rotor unmanned aerial vehicle. The coaxial dual-rotor unmanned aerial vehicle comprises a main shaft, an upper rotor assembly, a lower rotor assembly, an upper motor, a lower motor and a rotor control device. Wherein the upper rotor assembly is pivotally arranged on the main shaft; the lower rotor assembly is pivotally arranged on the main shaft; the upper motor is in driving connection with the upper rotor assembly; the lower motor is in driving connection with the lower rotor assembly, and the rotation directions of the upper rotor assembly and the lower rotor assembly are opposite; and the rotor control device is in driving connection with the lower rotor assembly so as to perform periodic variable-pitch control on the lower rotor assembly. According to the technical scheme, a transmission mechanism of the unmanned aerial vehicle is simplified in a motor direct drive mode, so that the structure of the coaxial dual-rotor unmanned aerial vehicle is more simplified, and the coaxial dual-rotor unmanned aerial vehicle has the following three advantages that firstly, weight reduction design is facilitated; secondly, the damage probability of parts is reduced, the reliability of the coaxial dual-rotor unmanned aerial vehicle can be improved, and the service life of the coaxial dual-rotor unmanned aerial vehicle can be prolonged; and thirdly, processing and assembling are facilitated, and mass production is facilitated.
