description Provided are a cleaning robot that travels while avoiding liquid and a method for controlling the cleaning robot. The cleaning robot may: control a light radiation unit to radiate light having, as a peak wavelength, a light-absorption wavelength determined on the basis of the light-absorption properties of water, toward a surface-to-be-cleaned in the traveling direction of the cleaning robot; receive, through an infrared light sensor, infrared light of the light-absorption wavelength among the light reflected from the surface-to-be-cleaned, and receive, through a visible light sensor, visible light reflected from the surface-to-be-cleaned; determine, on the basis of the received infrared light and visible light, whether there is liquid on the surface-to-be-cleaned; and control a travel module on the basis of determining that there is liquid on the surface-to-be-cleaned, so that the cleaning robot can be moved to avoid the liquid. L'invention concerne un robot de nettoyage qui se déplace tout en évitant un liquide et un procédé de commande du robot de nettoyage. Le robot de nettoyage peut : commander une unité de rayonnement de lumière pour émettre de la lumière ayant, en tant que longueur d'onde de pic, une longueur d'onde d'absorption de lumière déterminée sur la base des propriétés d'absorption de lumière de l'eau, vers une surface à nettoyer dans la direction de déplacement du robot de nettoyage ; recevoir, par l'intermédiaire d'un capteur de lumière infrarouge, une lumière infrarouge de la longueur d'onde d'absorption de lumière parmi la lumière réfléchie par la surface à nettoyer et recevoir, par l'intermédiaire d'un capteur de lumière visible, une lumière visible réfléchie par la surface à nettoyer ; déterminer, sur la base de la lumière infrarouge et de la lumière visible reçues, s'il existe un liquide sur la surface à nettoyer ; et commander un module de déplacement sur la base de la détermination du fait qu'il existe un liquide sur la surface à nettoyer, de sorte que le robot de nettoyage peut être déplacé pour éviter le liquide. 액체물을 회피하여 주행하는 청소 로봇 및 청소 로봇의 제어 방법이 제공된다. 청소 로봇은 광조사부를 제어하여, 청소 로봇의 주행 방향의 피청소면을 향해 물의 흡광 특성에 기초하여 결정된 흡광 파장을 피크 파장으로 갖는 광을 조사하고, 적외광 센서를 통해, 피청소면으로부터 반사된 광 중 흡광 파장의 적외광을 수신하고, 가시광 센서를 통해, 피청소면으로부터 반사된 가시광을 수신하고, 수신된 적외광 및 가시광에 기초하여 피청소면에 액체물이 있는지 여부를 결정하고, 피청소면에 액체물이 있는 것으로 결정함에 기초하여, 주행 모듈을 제어하여 액체물을 회피하도록 청소 로봇을 이동시킬 수 있다.
