Abstract: A moving robot includes a main body which forms a space therein, a noise generating member which is disposed inside the main body and generates a noise, an inner housing and an outer housing which surround the main body, and two or voice recognition members which are disposed in the housing and are disposed to be separated from each other, and a noise recognition member which recognizes a noise. The voice recognition members are disposed on a side opposite to the noise generating member based on a central point and disposed to be separated from each other along an outer peripheral surface of the housing. Accordingly, a voice command is determined by a difference of the voice data acquired by the two voice recognition members separated from each other and noise data recognized by the noise recognition member to improve voice recognition efficiency.

Abstract: A moving robot may include a main body which forms a space therein, an inner housing which surrounds the main body, an outer housing, two voice recognition members/devices (or voice sensors) which are disposed in the housings and are disposed to be separated from each other, and a microphone mount which is supported by the inner housing and causes the voice recognition device to be in close contact with the outer housing. The microphone mount may include a bending prevention rib which is disposed below the microphone mount to prevent bending of the microphone mount, and a twist prevention rib which is disposed below the microphone mount to prevent twisting of the microphone mount.
