FIELD: physics, robotics.SUBSTANCE: invention discloses a robotic cleaner and a control method therefor. First, the direction and position of a sound source can be detected by one or more microphones, e.g., three microphones, and the characteristic sound of an event can be recognised. The recognised characteristic sound of an event can be output to the housing of the cleaner in the form of a message or can be provided through a communication network. This may enable to easily monitor the environment. Secondly, the sound recognition function can be updated by ambient sound for recognition of sound from background noise and ambient noise in a reliable and accurate manner. This may improve the rate of sound recognition and improve stability and efficiency. Thirdly, the robotic cleaner may move in the detected direction or towards the position of the sound source relative to the sound of an event. Image information may then be detected or it may be determined whether an unusual situation has occurred. Such information may be provided via a communication network.EFFECT: improved design.20 cl, 8 dwg |
