[SO-101] Gripper alignment and pick repeatability for educators schools (intermediate)
SO-101 discussion on gripper alignment, object approach consistency, pick repeatability, and practical tuning for classroom tasks.
SO-101 pick-and-place tasks often look almost solved: the arm reaches the right area, but the gripper approaches inconsistently and task success drifts across repeated runs.
How are you improving gripper alignment and pick repeatability on SO-101 without turning the lesson into endless retuning?
Please share how you check end-effector alignment, object fixtures, approach paths, and the smallest calibration tweak that produced a noticeable consistency gain.
If you reply, include one exact repeatability failure and one exact adjustment that improved results.
This question is most useful when replies say whether the problem came from calibration, fixture placement, gripper mechanics, or trajectory design.
If your lab found one small change with a big effect, such as an approach offset or object fixture, mention it clearly.
Searchers often want a classroom-friendly improvement, not a perfect industrial setup. Practicality matters here.
