Abstract: The present disclosure provides a robot and an audio data processing method thereof. The robot includes a body part, a main control module, and a sound pickup module electrically coupled to the main control module. The sound pickup module includes N microphones distributed around the body part to collect audio data. The main control module is configured to obtain the audio data of a sound source from a part of the N microphones collecting the audio data of the sound source without blocked by the body part, and perform a sound source localization and a sound pickup based on the obtained audio data. The 360-degree wake-up and sound source localization of the robot and the beam-forming of directional beams are realized. In addition, the sound pickup is realized without forming microphone holes on the head of the robot, hence the aesthetics of the robot will not be affected.
