Patent number: 8973210Abstract: Provided is a robot cleaner. In an embodiment, the robot cleaner for avoiding obstacles and sucking foreign materials using a plurality of sensors and a suction motor is characterized in that a drive suppression unit for detecting obstacles having a corresponding height is integrated with a base for forming a lower portion of a main body in order to not climb obstacles of a constant height during a driving period of the robot cleaner. The present disclosure according to the embodiment improves drive stability of the robot cleaner by sensing a threshold in erroneous state of the sensor for sensing the threshold.Type: GrantFiled: June 30, 2009Date of Patent: March 10, 2015Assignee: LG Electronics Inc.Inventors: Sung-Guen Kim, In-Bo Shim, Byung-Doo Yim, Ji-Hoon Sung, Bong-Ju Kim
