like pretty much every delivery person and warehouse worker in the country?
Their job description also includes knowing what to pick up with minimal instructions and an extremely low error rate, as well as where to take it and when and how to drop it off, the ability to work for up to 12 hours repeatedly and reliably, independence from wall power, and the ability to deviate from this routine where and when required in reasonable ways.
Are you describing robots or people? Sounds like a job description suitable for a mobile robot. A human worker isn't going to magically know where to pick something up or where to take it unless some central system tells him to. And a robot is equally able to follow instructions like: "Go pick up item 718281718 from bin 7891 (use your scanner to find the right item), box it and walk it over to loading dock 287 for immediate shipping. There's a liquid spill in aisle 27, find your own way around it."
