1. A method of controlling a robot comprising:
identifying that an audio signal input through a plurality of microphones on the robot corresponds to a coughing sound,
based on the audio signal input through the plurality of microphones on the robot being identified as corresponding to the coughing sound, identifying an originating direction of the audio signal based on an arrangement direction of each microphone and a difference in intensity of audio signals that are respectively input to the plurality of microphones, wherein the plurality of microphones are arranged in different directions;
based on the audio signal input through the plurality of microphones being identified as corresponding to the coughing sound, capturing an image in the originating direction of the audio signal corresponding to the coughing sound using a camera on the robot;
identifying a sterilization area based on a position of a non-mask wearing user identified from the image; and
moving the robot to the sterilization area.
