Autonomous mobile robot cleaner
First Claim
1. An autonomous mobile robot cleaner having a main body, comprising:
- an obstacle detection means to detect an obstacle around the main body;
a moving means to move and turn the main body;
a cleaning means to clean an area in which the main body moves;
a cleaning operation control means to control the moving means and the cleaning means based on an output of the obstacle detection means so as to clean, while moving the main body, the area in which the main body moves;
a dust sensor to detect dust collected by the cleaning means; and
a dust concentration decision means to decide degree of dust concentration in the area in which the main body moves based on an output of the dust sensor, wherein the cleaning operation control means performs a basic cleaning operation to move the main body according to a predetermined movement procedure, and wherein when an area exceeding a reference value in the degree of dust concentration is found using the dust concentration decision means, the cleaning operation control means performs a local cleaning operation to move the main body locally in the area exceeding the reference value in the degree of dust concentration after the cleaning operation control means moves the main body in accordance with the basic cleaning operation in the area exceeding the reference value in the degree of dust concentration.

Abstract
An autonomous mobile robot cleaner that can thoroughly clean an area of high dust concentration. The robot cleaner includes a dust sensor to detect collected dust and a dust concentration decision means to decide degree of dust concentration in the area in which the main body of the robot cleaner moves based on an output of the dust sensor. The robot cleaner performs a basic cleaning operation while moving according to a predetermined movement procedure. When it finds an area in which the degree of dust concentration is above a given value using the dust concentration decision means during the basic cleaning operation, it additionally performs a local cleaning operation to move locally in such area after its movement in accordance with the basic cleaning operation.
