Abstract: A sound source classification step according to an exemplary embodiment of the present disclosure includes the steps for detecting a sound stream for a preset period when a sound signal is generated, dividing the detected sound stream into a plurality of sound frames and extracting a sound source feature for each of the plurality of sound frames, and classifying each of the sound frames into one of pre-stored reference sound sources based on the extracted sound source feature, analyzing a correlation between the classified reference sound sources using the classification results, and classifying the sound stream using the analyzed correlation.

Abstract: Disclosed is a disinfection robot capable of autonomous driving and recognition of a disinfection target. The disinfection robot includes: a recognition unit configured to generate recognition information by recognizing a surrounding environment of the disinfection robot; a movement unit configured to move a position of the disinfection robot; a light source unit configured to emit a light of a predetermined wavelength area for disinfection; an injection unit configured to inject a fluid for disinfection; and a control unit configured to move the disinfection robot through the movement unit based on the recognition information, wherein the control unit is configured to identify a disinfection target from the recognition information and control at least one of the light source unit and the injection unit to perform disinfection to at least one of the surrounding environment of the disinfection robot and the disinfection target.

Abstract: A human-following robot for searching a following target when failing to track the following target includes a location estimating module configured to estimate a location of the following target based on map information and trajectory information, a search range setting module configured to set a search range of the following target based on the estimated location information and human walking pattern information, and tracking module configured to track the following target after moving to the search range. Since the robot estimates a location of a missed following target and the moves to the estimated location by utilizing map information and human walking pattern information including walking pattern data of persons in a surrounding environment, which is accumulated during a predetermined period, the following target may be detected again.
