See three precision parallel grippers on one UR3e cobot in this demo from Eastec 2019.

The three grippers take five different precision measurements of a small part, enable in-process decisions, and record the data.

“I love this gripper” says UR’s Zach Tomkinson. “The fact that its capable of doing extremely precise grips… you can use it as a contact measurement, for a decision if it’s a few thou difference – to make a decision to do something differently with the product.

“You can’t do that with any other type of gripper that UR works with.”
