Document Type and Number:
WIPO Patent Application WO/2017/200304
Kind Code:
A3
Abstract:
A mobile robot of the present invention emits a first-patterned light towards a floor in a cleaning area in front of a main body, and a second-patterned light towards the upper front direction with respect to the main body, determines an obstacle by means of an image in which the patterned lights that are emitted are respectively incident on an obstacle, and compensates for inclination by detecting the inclination of the main body, and thus may make an accurate determination regarding the obstacle, and may pass through or avoid the obstacle by re-determining, through the inclination compensation, whether travelling is possible, and thus is capable of accessing various areas, thereby expanding the range of areas that may be cleaned, and may effectively travel by being capable of determining and operating quickly, and escaping without being constrained by an obstacle.
