What a robot will not do at your station

The person at that station is doing more than the task you would describe if we asked. Naming the rest before you buy is the difference between a happy installation and a disappointed one.

Ask what happens at a packing station and you will be told that somebody packs cases. Stand there for a shift and you will see something wider. They glance at each item and catch the obvious defects. They notice when the tape is running out. They restack a leaning pallet. They rescue the part that fell. They tell the supervisor when something upstream started going wrong twenty minutes before the data would have shown it.

None of that appears in a job description and none of it is in the scope of a cell. It is genuine work, it has value, and when the station is automated it does not disappear. It relocates, usually to whoever is nearest, and if nobody planned for that, it lands on someone already busy or it stops happening at all.

The one that matters most is incidental inspection. In a lot of plants, the reason a defect never reaches a customer is that somebody handling the product noticed. Automate the handling without adding an inspection step and your escape rate can rise even though nothing about your process got worse. That is a genuinely unpleasant surprise to have after installation, and it is entirely predictable beforehand.

This is not a reason to avoid automating. It is a reason to write down, honestly, what the person at that station actually does across a full shift, and then decide for each item whether the cell covers it, a different person covers it, or you accept losing it. Most of the time that exercise is quick and the answers are easy. The value is in having asked rather than assumed.

It also usually improves the project. Once the invisible work is on paper, it often turns out that the right scope is slightly different from what was first proposed: an added camera check, a different handoff point, an operator role redefined rather than removed. Those adjustments cost far less at the scoping stage than after commissioning.

When we describe a cell, we try to say plainly what it will not do before we say what it will. A customer who knows the boundary is a customer who is satisfied on day one. A customer who discovers it is a customer who feels sold to, and they are right to.
