[0002] AMR dolly needs to be positioned accurately when butting with fixed gun rack, the existing method usually extends an iron sheet on the gun rack, an M30 proximity switch is installed on the front end of AMR dolly, when AMR dolly approaches the gun rack, the iron sheet will be sensed, at this time, AMR stops.

[0003] Because the gun rack is fixed on the ground, when the customer inserts or pulls out the gun, the gun rack is easily pulled or pushed, after frequent operation, the gun rack is warped, so that the distance between the iron sheet and the ground is increased. When AMR dolly approaches the gun rack again, the iron sheet cannot be sensed, so that the positioning is inaccurate.

[0004] Another common method is to place a camera at the bottom of AMR, and to complete accurate positioning by taking a photo of the ground two-dimensional code at a certain position. The camera placed at the bottom of AMR and the ground two-dimensional code are affected by the light in the parking lot, and the intensity of light that is too large or too small will affect the recognition and positioning of the camera, and further cause AMR dolly to be unable to butt accurately.
