4.9.4. Find Visual Offset node
This node is used to calculate by how much a tag was moved, in reference to its value as calibrated previously. The value of the offset
found by this Find Visual Offset node is temporarily saved, and you can reapply it in a Apply Visual Offset node. In the program, the
condition " If tag found" is under the Find Visual Offset node. If no tag is found, no visual offset is applied to the robot program . If a
tag is found, a visual offset is applied, and the robot moves to take a closer picture (" close_tag_pos" ). A Find Visual Offset node is run
again at a close distance (recommended distance is 15 cm max). Then, the value of the offset found at this step is used by an Apply
Visual Offset node, which applies it to the " Call pick" routine.
Here is how to use the Find Visual Offset node.
1. Select the Find Visual Offset node
from the left navigation pane.
2. Tap Select Tag button.
3. The ''Select Tag For Visual Offset''
window is displayed. Tap the tag
you wish to use for your Find Visual
Offset node.
