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 th

Example Embodiment

[0106] The expression of the direction in the "front f / post R / left LE / right ri / upper U / lower D" mentioned below is defined as shown in the figure, but this is merely to illustrate the present invention and can be clearly understood, of course, Each direction can be defined differently depending on the placement position of the reference.

[0107] For example, the direction parallel to the center axis of the central axis of the left side rotation mop and the right rotating mop is defined as the left-right direction, and the left-right direction is vertically intersected, and the central axis of the rotary mop is parallel or error. The direction within 5 degrees is defined as the up and down direction, defined as the direction in which the vertical intersection of the left-right direction and the up and down direction is the front-rear direction. Of course, the front direction can refer to the main travel direction of the main travel direction or the Pattern of the mobile ...

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...
