Robot cleaner
First Claim
1. A robot cleaner which sucks foreign substances on an area to be cleaned while avoiding an obstacle using a plurality of sensors and a suction motor, the robot cleaner comprising:
- a base defining a lower portion of a main body; and
a drive suppression unit integrated with the base, the drive suppression unit interfering with an obstacle having a predetermined height to prevent the robot cleaner from passing over the obstacle having the predetermined height,wherein the drive suppression unit comprises;
a sensor receiving groove in which a portion of the base is recessed to provide a mounting space of a detection sensor for detecting a threshold or cliff; and
a hook in which a portion of the base relatively protrudes due to the recession of the sensor receiving groove to interfere with the obstacle.

Abstract
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.
