Abstract
The present disclosure relates to a robot cleaner and a control method therefor, the robot cleaner being capable of accurately identifying the type of contaminant in a cleaning space and performing cleaning by using an appropriate method accordingly, wherein the control method comprises the steps of: obtaining, through a camera, an image in a cleaning space; detecting a contaminant in the image; if the probability of accuracy of the type of the detected contaminant exceeds a first threshold, performing cleaning by using a method corresponding to the type of the detected contaminant; if the probability of accuracy of the type of the detected contaminant is less than a second threshold, ignoring the detected contaminant; and if the probability of accuracy of the type of the detected contaminant is no greater than the first threshold and no less than the second threshold, applying different external stimuli toward the detected contaminant according to the type of the detected contaminant to thus identify the type of the detected contaminant.
