Walmart Running Into Trouble as Its Super-Expensive Robots Can’t Handle the Realities of Warehouse Work: It's an automation "arms race."

Walmart spent billions replacing warehouse workers with robots, only to discover the robots can’t lift dog food and the engineers cost more than the workers did. Apparently the automation revolution has reached its greatest technical challenge yet: doing the job it was supposed to automate. Somewhere, a PowerPoint deck is quietly being deleted.

The system designers get tripped up by the strangest things. I once worked in a factory that uses copper bars of varying lengths, and the designer didn’t expect the bars to ‘sag’ when picked up flatwise from the middle. So I can imagine picking up a bag of dog food would do that.
