Moving robot

A robot comprising:

• a main body that provides an inner space therein;
• a plurality of noise generating devices disposed at the inner space, and configured to generate a noise;
• a housing that covers the main body;
• a dust container configured to separate dust through a cyclone flow:
• and
• a plurality of voice sensors disposed to be separated from each other,
• wherein when viewed from above, the plurality of noise generating devices and the plurality of the voice sensors are arranged on opposite sides of a reference line passing through a central point of the main body and a center of the cyclone flow, a first virtual line passing through each of the plurality of noise generating devices and a second virtual line passing through each of the voice sensors are on opposite sides of the reference line, and
• wherein a shortest distance between the reference line and each of the plurality of noise generating devices is shorter than a shortest distance between the reference line and each of the plurality of voice sensors
• wherein based on a forward direction of the robot, the reference line connects a center of a front end of an upper surface of the housing and a center of a rear end of the upper surface of the housing, and
• wherein, when viewed from above, the plurality of voice sensors is disposed outside of the dust container.
