Abstract

In order to solve the problem of the present invention, an autonomously traveling vacuum cleaner according to an embodiment of the present invention includes: a main body; a drive unit for moving the main body; a camera for detecting three-dimensional coordinate information; a memory for station-related pattern information; and a control unit for comparing the three-dimensional coordinate information detected by the camera with pattern information about the charging station stored in the memory, and based on The results of the comparison are used to determine whether the charging station is located near the subject.

Description

technical field [0001] The present invention relates to a cleaner and a control method thereof, and more particularly, to a cleaner capable of identifying obstacles and performing autonomous travel and a control method thereof. Background technique [0002] Typically, robots have been developed for industrial use and have managed some parts of factory automation. As robots are recently applied to various fields, not only medical robots and space robots but also household robots are being developed. [0003] A representative of home robots is a robot cleaner, a home electronic device capable of performing cleaning operations by sucking in dust or foreign matter while autonomously moving over a predetermined area. This robot cleaner is provided with a rechargeable battery, and is provided with an obstacle sensor for avoiding obstacles while autonomously moving. [0004] Recently, in order to utilize robot cleaners in various fields such as health care, smart homes, and remot...
