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.
