Abstract: A rotary wing drone according to one embodiment of the present invention comprises: a flight control unit for controlling the flight of the rotary wing drone; a main body including a first motor and a second motor; an upper shaft vertically inserted into the main body and rotating in a first direction around a first axis by means of the force of the first motor; a plurality of upper rotor blades connected to the upper shaft such that the plurality of upper rotor blades rotate in the first direction around the first axis at a fixed pitch angle; a lower shaft vertically inserted into the main body and rotating in a second direction opposite to the first direction around the first axis by means of the force of the second motor; a plurality of lower rotor blades and a swash plate connected to the lower shaft so as to rotate in the second direction around the first axis and having a variable pitch angle; a slope regulator for regulating the slope of the swash plate; a link part for connecting the swash plate to th

Abstract: A device controller and data processing method thereof are disclosed. According to the present invention, the device controller for controlling a digital device includes a cover, an upper core part including an input unit, a lower core part including an interface unit, and a core including a core body combined with the upper core part and the lower core part. The core body includes a communication module configured to transmit and receive control signals for controlling the digital device, a first sensor module configured to sense motion data according to a movement of the device controller, a second sensor module configured to sense pressure applied to the core body, a control unit configured to control operations of the modules, collect data sensed by the sensor modules, generate a control signal based on the collected sensed data, and output feedback.
