Robotic cleaner and control method therefor

Abstract

A robotic cleaner is disclosed. The present robotic cleaner comprises: a main body; a driving unit provided to the main body so as to supply power for the traveling of the robotic cleaner; first and second rotating members which respectively rotate around a first rotary shaft and a second rotary shaft by the power of the driving unit, so as to provide a movement power source for the traveling of the robotic cleaner, and to which cleaners for wet-cleaning can be respectively fixed; and a control unit for determining a cleaning travel pattern of the robotic cleaner, and controlling the driving unit such that the driving unit travels while successively repeating forward and backward movements, according to the determined cleaning travel pattern.

Description

technical field [0001] The present invention relates to a cleaning robot and a control method thereof, and more specifically, to a cleaning robot capable of traveling freely while performing wet cleaning and a control method thereof. Background technique [0002] With the development of industrial technology, many devices have been automated. As we all know, a cleaning robot is a machine that automatically moves to the area that needs to be cleaned without human operation, absorbs foreign objects such as dust from the surface to be cleaned or wipes the foreign objects on the surface to be cleaned, thereby automatically cleaning the area that needs to be cleaned. [0003] Generally, the cleaning robot may include a vacuum cleaner, and the vacuum cleaner utilizes a power source such as electricity to clean through suction. [0004] However, the cleaning robot including the vacuum cleaner cannot remove foreign matter or stubborn stains adhering to the surface to be cleaned. Th...

Problems solved by technology

[0004] However, the cleaning robot including the vacuum cleaner cannot remove foreign matter or stubborn stains attached to the surface to be cleaned, so cleaning robots that attach a rag to the cleaning robot and perform wet cleaning have become popular recently.

[0005] However, the wet cleaning method using a general cleaning robot is only a simple method of attaching a rag or the like to the lower part of the conventional cleaning robot for vacuum cleaning, so there is a disadvantage that the removal efficiency of foreign matter is low, and wet cleaning cannot be performed effectively.

[0006] Especially, its wet cleaning method of common cleaning robot is to utilize the moving mode of existing suction type vacuum sweeper and the mode of avoiding obstacles etc. to travel as before, therefore, still exist even if remove the dust etc. scattered on the surface to be cleaned, It is also difficult to remove foreign matter adhering to the surface to be cleaned, etc.

[0007] In the structure where the rag is attached to the general cleaning robot, since the friction between the surface of the rag and the ground becomes higher, a greater driving force is required to move the wheels, so there is a problem of increased battery consumption.
