Use one wrist-camera snapshot position and evaluate that view with a separate CamLocate node for every color class. For three otherwise similar red, green, and blue parts, configure three nodes: one for red, one for green, and one for blue.

Build One Detection Branch per Color

Color class Required detection node Resulting action
Red CamLocate configured for red Route to the red-part destination
Green CamLocate configured for green Route to the green-part destination
Blue CamLocate configured for blue Route to the blue-part destination

The evidence supports one CamLocate node per color; it does not identify camera settings, node parameters, or software versions. Determine those values from the actual image and installed system instead of copying assumed settings.

Configure the UR3 Sorting Sequence

  1. Move the UR3 to the selected snapshot position.
  2. Configure one CamLocate node to detect the first color.
  3. Duplicate the detection structure for each additional color, then configure each node for its own color class.
  4. Connect each successful color result to the corresponding sorting destination.
  5. Provide a separate outcome when none of the color nodes detects a part; the evidence does not define the required recovery action.

Verify Detection Before Running Production

Present each supported color at the same snapshot position and confirm that its assigned CamLocate node detects it and selects the correct destination. Also test the other color nodes against that part. If more than one node reports a match, the evidence does not define priority or exclusivity; refine the color configurations and retest before enabling automatic sorting.

Test a scene with no supported color and confirm that the program does not silently route the part as a valid class. Detection robustness under changing lighting, part orientation, or background is not established by the evidence, so validate the actual installation across its operating conditions.

FAQ

How many CamLocate nodes do I need to sort three colors?

Use three CamLocate nodes: one configured for red, one for green, and one for blue.

Can one UR3 camera snapshot position detect multiple colors?

Yes. Evaluate the same snapshot position with a separate CamLocate node for each required color class.

What should I check if two color nodes detect the same part?

The evidence does not define a priority rule. Refine the affected color configurations, then present each color again and verify that only its intended node reports a match.
