1. Paste QR code
Tools required:
Tape measure
Coated paper: Frosted film, 110*110mm (Figure 1)
At least two ground-attached instruments (Figure 2)

1.1 Use QR codes for navigation to meet requirements
The standard spacing between the two QR codes is 1m. The QR code must be set at the turning point of the robot.
The X and Y axes on the two-dimensional code must be aligned with the ground line (with an error control of within 3°).
The number of the two-dimensional code on the ground should increase gradually in accordance with the X-axis and Y-axis directions.
No QR code with the same number should be used in the area.
It is recommended that the X axis and Y axis directions of the two-dimensional code be consistent as far as possible.
1.2 Two-dimensional code for secondary positioning
The X-axis orientation of the QR code should be consistent with the expected front orientation of the robot arriving at this point.
If the up-view PGV is used, the QR code needs to be pasted in the center of the bottom of the shelf.
If the down-viewing PGV is used, the QR code needs to be pasted on the ground at the corresponding position.
1.3 Pasting Procedure
1.3.1 Select the starting point and paste the two-dimensional code, as shown in the figure below.

1.3.2 Use a tape measure to measure a distance of 1 meter, parallel to the laser line.

1.3.3 Align the center coordinates and paste.

1.3.4 Apply film coating after pasting.
