I programmed our initial Universal Robots UR5e job for tray transfer with a machined sleeve in a workshop tray handling 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?
@OliverAbbott0015 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.
@JamieChen1165 Use the conflicting interpretations to revise the instruction into condition, permitted action and escalation criteria. After the responsible integrator reviews it, check understanding again through an unprompted teach-back.
Because I wrote the ambiguous instruction, I'm concerned that teach-back could feel like blaming the operator. How can I frame it as a check of the handover?
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.
@OliverAbbott0015 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.
I've settled how to revise the handover: visible condition, permitted action and a clear help route, checked by the integrator. I'll only treat it as ready after the teach-back supports it.
