[Orca Hand] Grasp labels shift after fingertip material change for builders researchers (intermediate)

How do you tell when Orca Hand data stopped meaning the same thing after a fingertip material swap changed friction and contact behavior?

An underappreciated Orca Hand data-quality problem appears after changing fingertip pads or surface material. Grasps may still work, but slip behavior, contact timing, and label meaning drift enough that old and new data no longer represent the same policy target.

How are you diagnosing grasp-label drift on Orca Hand after a fingertip material change?

Please share how you compare old versus new grasp outcomes, which signs tell you the issue is data-definition drift instead of simple wear, and what relabeling or segmentation decisions keep your dataset trustworthy after the hardware change.

If you reply, include one exact labeling symptom and one exact comparison or QA step that exposed the drift.

Comment 1

The best replies explain whether the drift first appeared in slip rate, contact timing, or annotation disagreement.

Comment 2

If one before-and-after grasp benchmark exposed the problem quickly, share it. That QA gate is what many searchers need.

Comment 3

It also helps to explain when you fork a new dataset segment instead of mixing data across material changes.
