[SO-101] Gripper alignment and pick repeatability for educators schools (intermediate)
#1 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.
#3 If your lab found one small change with a big effect, such as an approach offset or object fixture, mention it clearly.
#4 Searchers often want a classroom-friendly improvement, not a perfect industrial setup. Practicality matters here.
This question is most useful when replies say whether the problem came from calibration, fixture placement, gripper mechanics, or trajectory design.
