Abstract: Disclosed is a device, system, and method for controlling a UAV. According to the disclosure, a device for controlling a UAV may be related to artificial intelligence (AI) modules, robots, augmented reality (AR) devices, virtual reality (VR) devices, and 5G service-related devices.

Abstract: An altitude measuring method of an unmanned aerial robot is provided. The robot adjusts a level of the unmanned aerial robot so that the robot is at a horizontal state with respect the ground to measure the altitude. The robot generates a plurality of laser beams to the ground, and photographs the ground through the camera. The robot calculates a vertical distance from the ground to the robot based on the photographed image of the ground and the plurality of laser beams.

Abstract: A flight system for indoor positioning includes an unmanned aerial robot, and a station and a server of the unmanned aerial robot. The unmanned aerial robot may sense a plurality of laser beams generated from the station through a first camera and/or a first sensor, perform adjustment such that a horizontal axis position of the unmanned aerial robot is located at a center position of a measurement space for the indoor positioning based on the plurality of sensed laser beams, and perform positioning in the measurement space while flying in a vertical direction.

Abstract: The present invention provides a method for charging a battery of an unmanned aerial robot at a station. More specifically, the station monitors a voltage of the battery and charges the battery using wired charging or wireless charging when the voltage of the battery is a threshold voltage value or less. The station controls the unmanned aerial robot such that the unmanned aerial robot performs a specific operation to lower the voltage to a predetermined voltage or less when the voltage is higher than a specific level. The specific level is the specific level is one of a plurality of levels classified according to whether or not the voltage is lowered to the predetermined voltage or less through the specific operation within a first specific time and the specific operation is changed according to each of the plurality of levels.

Abstract: A mobile terminal including a touch panel including a plurality of touch panel electrodes; a stylus pen configured to perform transmission and reception of an electric signal with the touch panel using capacitive coupling and without using a separate power supply to the stylus pen; and a controller configured to, when the electric signal is received from the stylus pen through the capacitive coupling, detect a location of the stylus pen with respect to the touch panel based on signal magnitudes of at least two touch panel electrodes from which the electrical signal is detected.

Abstract: A mobile terminal having a stylus pen and a touch panel is provided. The mobile terminal includes a touch panel having a plurality of touch panel electrodes, and a stylus pen provided to transmit and receive an electrical signal to and from the touch panel using capacitive coupling, wherein the stylus pen includes a main body, a pen tip formed of a conductor and protruding to outside of the main body to apply a touch to the touch panel, and an LC circuit provided within the main body, configured to include an inductor and a capacitor, and electrically connected to the pen tip to generate capacitive coupling between the LC circuit an the touch panel.
