Gripper gripps wrong compent

Hello,

I modeled a gripped which is supposed to grip a workpiece from the downside.

When the gripper is trying to grip the part, it grips the workpiece deposit instead.

As far as I could figure out, the problem is the DetectionVolumeSize. But the ways I tried to adapt the size, it either didn’t grip anything or still gripped the deposit.

Any idea how to solve this issue?

 

Thanks and best regards
