Wired writes about smart robots at work in warehouses like those of online shoe seller Zappos. The little guys go and “fetch” products needed by their human masters. They are “pickers.” I was a picker - made good money back in the day $4.15/hour at the SKYR warehouse in my home town.
But the robots are smarter than I was as a high school kid: they not only find the product and re-route themselves back to the requester, but they find time for the 5 minute/hour charge they require and help reorganize the wares for better efficiency.
The warehouse, says those behind the robots are 2 to 4 times as efficient with the robots. I’ll bet.
