Hi,
We have a line with 10 pickers and 3 camera. The 2 first camera has 3 pickers and the last one 4 pickers. We have some troubles when picking product with object rotation allowed. It seems to be not correct to use the work area tune to adjust the pick position because the rotation of the object . Is it correct ? We need to use the grip location to adjust the pick position. Is it still correct ? If I want to adjust the pick position of each robot will it mean that I need 1 pick item for each robot ?
Thanks in advance.

Hello,
make a Calibration Verification, and if necessary adjust the camera calibration tune and the base frame tune. If you have got a proper initial calibration of the line, the programmed grip location (relative the item) should always be repeatable also when using different item orientations. The grip location should not be tuned if there is a problem with different item orientations. Use the work area tune to compensate for smaller pick offsets only.

Hi,
I found out the problem, the problem was comming from a wrong robot calibration on the single axis, only 3 of the 10 pickers where correct calibrate, I found out this problem by doing a pick and place program : 300 mm displacement in x and y direction, the robot was doing 301-302 mm in x direction that’s not good. So we have decided to check all the robots with the ABB calibration tool, the biggest difference that we found was -12.3? instead of 13.2? that’s realy huge. How could this happen ???
