[SO-101] Gripper alignment and pick repeatability for educators schools (intermediate)

How are you making SO-101 pick-and-place tasks repeatable enough for demos and classes instead of succeeding only once in a while?

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.

Comment 1

The strongest replies will explain whether repeatability improved through calibration, fixture design, path design, or gripper adjustment.

Comment 2

If your team found that one object shape or one approach angle exposed the problem fastest, include that detail. It makes the answer easier to reuse.

Comment 3

Classroom-friendly methods are especially welcome because many readers will be trying to stabilize simple demonstrations first.
