An empty pocket leaves our operators guessing - tray transfer

I programmed our initial Universal Robots UR5e job for tray transfer with a machined sleeve in a supervised assembly training cell and handed it over to the operators. They can start the saved job, but they need me when a pocket is empty or a run is interrupted. I suspect the handover omitted recovery decisions, rather than the operators lacking willingness.

A teach-back could reveal where the handover becomes unclear. What do operators understand the restart instruction to mean when they explain it without prompts?

I tried that in a discussion. Several people read the same restart line differently. So yes, we've handed over an instruction that doesn't agree with itself.

Rewrite that line around the visible condition, permitted next step and when to call for help. Have the responsible integrator check it, then repeat the teach-back without prompting.

How do I stop teach-back feeling like a test of the operator? The wording was mine. I don't want to make that their failure.

@MinaCarter1033 On my setup, I asked people to find where my guide forced them to guess. That invited corrections instead of making them defend a wrong answer.

Once the recovery sheet is clear and available at the controls, the team should no longer need to call you about these interruptions.

Not if the system can't tell them what's physically happening. Better wording can't create a recovery path for an unknown held-workpiece state.

@TheoBell0671 You're right; I promised too much from a sheet. The guide should support defined recoveries and clearly escalate unknown states. Some calls are the correct outcome.

Our original handover only showed an empty gripper at startup. It never covered an interruption with the workpiece still held. That's a real gap.
