Mobile robot

Abstract

The present invention is characterized in that: the center of gravity of the mobile robot is positioned on a virtual central vertical line and is positioned further forward than a virtual central horizontal line connecting the rotating shaft of the left-side rotating mop and the rotating shaft of the right-side rotating mop; the center of gravity of the mobile robot is located forward of the centers of gravity of the battery and the water tank, and is disposed rearward of the center of gravity of the sweeping module.

Description

technical field [0001] The invention relates to a mobile robot for wiping. Background technique [0002] A mobile robot is a device that cleans by sucking foreign matter such as dust from the ground or wiping foreign matter on the ground. More recently, mobile robots that can perform wiping are being developed. In addition, a mobile robot is a device that cleans while driving on its own. [0003] As prior art, a mobile robot capable of moving over the surface of a mop is known. In said prior art, a first rotating member and a second rotating member of a mobile robot for fixing a pair of rag surfaces arranged in a left-right direction are arranged on a vertical direction axis. The mobile robot in the prior art moves with the rotation of the first and second rotating members in a state where only the surfaces of the mopping cloth fixed to the first and second rotating members are in contact with the ground. [0004] In the case of the prior art, when water is supplied to t...

Problems solved by technology

When viewing the main body from the upper part, the sweeping robot is made circular for easy rotation and aesthetic appearance at the corners, at this time, if the agitator does not protrude from the main body, the width of the agitator is limited to the diameter of the main body, especially, the agitation The agitator is placed farther in front than the dust bucket and the spin mop, so there is a problem that the width of the agitator is only close to the radius

[0006] Therefore, in the case of the prior art, in order to increase the width of the agitator, there is a structure protruding toward the front of the main body of the dry module. This structure has the problem that the cleaning robot is not easy to rotate and the volume of the cleaning robot increases.

[0007] In addition, in the prior art, since the cleaning robot travels only by the frictional force of the rotating mop, and the water level of the water stored in the tank is variable, it is difficult to perform wiping efficiently, and there is a problem with the driving force

[0008] In particular, because existing wet robots are difficult to adjust the direction of travel through friction with the rotating mop, there is a disadvantage that they can only clean with random travel, but cannot perform pattern travel that can clean thoroughly.

[0009] In addition, the prior art has the disadvantage that it is difficult to thoroughly clean corners of the ground or areas near walls when only random driving is performed
