Specifically, Figure 3-4The front end of the robot body 1 is provided with a mounting structure for installing a measuring and releasing mechanism 2, and the measuring and releasing mechanism 2 includes a wheel body rotatably mounted on the mounting structure; a releasing structure composed of a plurality of releasing modules 22 is mounted on the outer peripheral side wall of the wheel body; a plurality of drainage ports are arranged at the center of the outer peripheral side wall of the wheel body; the releasing module 22 includes an arc block 221 attached to the outer peripheral side wall of the wheel body, a plurality of drainage channels are arranged on the arc block 221, and a sponge layer 220 or a cotton cloth layer is arranged on the outer side wall of the arc block 221; when in use, the ink stored in the wheel body infiltrates into the sponge layer 220 or the cotton cloth layer through the drainage port and the drainage channel, and then when the robot body 1 moves along the ground during use, the sponge layer 220 or the cotton cloth layer rolls along the ground to realize the releasing.
[0031] Then, when in use, when it is necessary to draw a solid line, the arc block 221 of each pay-off module 22 is controlled to be set opposite the discharge port. Conversely, when it is necessary to draw a dotted line, half of the pay-off modules 22 are controlled to move to one side of the wheel body. At this time, the arc block 221 of the pay-off module 22 leaves the discharge port. At this time, the pay-off module 22 cannot pay out the line when in use, thereby achieving the dotted line drawing mentioned above.

[0033] That is, when in use, in order to facilitate the control of the release module 22 to move along the axial direction of the wheel body, one side of the arc block 221 is connected to a surface of the substrate B211 located on the outer peripheral side of the convex edge B212 through an elastic telescopic column 223; the other side of the arc block 221 is connected to a side plate 225 through a connecting plate 224, and a magnet is embedded in the side plate 225; an electromagnet used in conjunction with the magnet is arranged on the opposite side of the substrate A201, and a guide hole 226 is opened on the side plate 225, and a guide column 227 passing through the guide hole 226 is arranged on the opposite side of the substrate A201; the elastic telescopic column 223 includes an inner sleeve and an outer sleeve that cooperate with each other, and a spring is connected between the inner sleeve and the outer sleeve; a power supply for powering the electromagnet is arranged in the robot body 1, so that when in use, it is convenient to control the power on and off of the electromagnet according to needs, and then use the principle of mutual repulsion and attraction between the electromagnet and the magnet to control the arc block 221 to move along the axial direction of the wheel body.
[0034] Specifically, in order to maintain the stability of the movement of the arc block 221 while controlling the movement of the arc block 221 along the axial direction of the wheel body during use, mutually cooperating guide grooves 221 and guide slide bars 222 are respectively provided at both ends of the arc block 221 .
[0035] It should be noted that if Figure 6-7 In order to facilitate the assembly of the first shell 20 and the second shell 21 during use, the present invention respectively provides mutually matching rectangular positioning sleeves 204 and rectangular positioning columns 214 on the opposite side walls of the substrate A201 and the substrate B211; three fixing bosses 205 are provided on the substrate A201, and threaded holes 206 are provided at the ends of the fixing bosses 205, and the ends of the fixing bosses 205 are sealed against the substrate B211; a through hole 215 matching with the threaded hole 206 is provided on the substrate B211; during installation, screws that pass through the through hole 215 and are threadedly connected to the threaded hole 206 are used for connection.
[0036] Specifically, in the present invention, in order to perform the wire-laying operation during use, that is, to adjust the position of the measuring wire-laying mechanism 2 relative to the robot body 1 during use, such as Figure 2 The present invention sets a rectangular groove A12 at the front end of the robot body 1, sets a guide rail A121 on the inner top side of the rectangular groove A12, and sets an electric slider A122 on the guide rail A121; the mounting structure includes a movable column 13 fixed on the end of the electric slider A122, and the movable column 13 slides along the inner wall of the rectangular groove A12 when in use; a U-shaped frame 14 is set at the end of the movable column 13, and rotating grooves matching with the rotating column 23 are respectively set on the two side walls of the U-shaped frame 14, an injection tube is set on the bottom side of the rotating groove, a through hole is opened on the rotating column 23, and the injection tube is inserted into the through hole; and an ink cavity is set in the robot body 1, and the ink cavity is connected with the injection tube.
[0037] It is known that when the line is actually laid out, if there is a lot of dust or sand on the ground, it will affect the ink's adhesion to the ground. Figure 2 A rectangular groove B11 is set on the robot body 1 located at the front end of the rectangular groove A11, a guide rail B111 is set on the inner top side of the rectangular groove B11, and an electric slider B112 is arranged on the guide rail A111.
