[Orca Hand] Fingertip material wear and slip during grasps for builders researchers (intermediate)
Orca Hand discussion on fingertip material wear, slip during grasps, surface maintenance, and how contact changes affect manipulation consistency.
Orca Hand grasp performance sometimes degrades for a very physical reason: fingertip material wears down, friction changes, and suddenly the same control policy no longer feels stable.
How are you diagnosing fingertip wear and grasp slip on Orca Hand over time?
Please share how you inspect surface wear, decide when to replace contact material, and separate hardware friction changes from control or thresholding issues.
If you reply, include one exact slip symptom and one exact maintenance or material change that improved consistency.
This thread is strongest when replies connect fingertip condition to a measurable change in grasp success or slip rate.
If you have a replacement rule or inspection schedule, post it. Searchers often want the boring maintenance answer.
It also helps to explain how you ruled out control tuning before touching hardware.
