Abstract: A robot and operation method is disclosed. The robot according to the present disclosure may include a sensor, a microphone, and a controller. The robot may execute an artificial intelligence (AI) algorithm and/or a machine learning algorithm, and may communicate with other electronic devices in a 5G communication environment. An embodiment may include detecting a movement of the robot to a location; detecting an obstacle within a predetermined range from the robot; estimating an occupation area of the obstacle in space; and identifying a sound signal received from the estimated occupation area of the obstacle from among a plurality of sound signals received by a plurality of microphones of the robot at the location.

Abstract: Provided is a robot cleaner. The robot cleaner includes a main body defining an outer appearance of the robot cleaner, a moving unit for moving or rotating the main body, a plurality of receiving units disposed in the main body to receive a user's voice command, and a control unit recognizing a call command occurring direction when the voice command inputted from the plurality of receiving units is a call command. The control unit controls the moving unit so that the main body is moved in the recognized call command occurring direction along the preset detour route.
