The robot cleaner performs cleaning using zigzag travel as a basic cleaning traveling manner, and then performs cleaning using random travel as a finishing cleaning traveling manner so as to clean areas skipped during the zigzag travel. The robot cleaner performs the zigzag travel while maintaining a designated interval with a travel route proceeding to a wall regardless of a direction proceeding to the wall, and employs an improved zigzag travel method to maintain a zigzag travel pattern, if the robot cleaner senses an obstacle during the zigzag travel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Robot cleaner and control method thereof","description":"Disclosed herein are a robot cleaner having an improved travel pattern and a control method thereof.
