At 5:40 on a Tuesday morning, the night shift at a distribution center outside the city is handing over to the day crew. The handover used to take ten minutes. Now it takes thirty, because half of the conversation is about the robots.
There are 212 of them on this floor: squat, orange machines that slide under shelving units, lift them and carry them to a row of packing stations. The workers call them “the turtles.” Management calls them autonomous mobile robots. Nobody calls them a threat anymore, at least not out loud.
What changed on the floor
Before the turtles arrived, a picker here walked an average of 11 miles a shift. Today the shelves come to them, and the walking has dropped to under two miles. Injury reports for strains and sprains are down by more than half, according to figures the company shared with Nexbrief.
“My feet don't hurt when I get home. That's the honest headline,” said one picker who has worked here for six years.
The pace has changed too. Each station now handles roughly 300 items an hour, up from about 100. Workers say the rhythm is relentless in a different way: there is no walk between picks, and no moment to look up.
The jobs that appeared
Automation did not empty the building. Headcount is roughly the same as three years ago, but the mix is different. The site now employs:
- Robot technicians who swap batteries and clear jams, a role that did not exist here in 2023;
- Floor coordinators who reroute traffic when a lane is blocked;
- Quality checkers who audit a sample of every packed order.
Several of those roles pay more than picking. Getting one, however, depends on a twelve-week training course that runs only twice a year, and the waiting list is long.
What did not change
Peak season still means mandatory overtime. Shift schedules still arrive by text message two days ahead. And for all the talk of smart systems, the most common reason a turtle stops is still a cardboard flap on the floor.
Researchers who study warehouse work say the pattern is familiar. A recent survey of 40 sites found that automation tends to shift strain rather than remove it: fewer injuries from walking and lifting, more complaints about pace and monotony.
What comes next
The company plans to add robotic arms to the packing stations next year. Workers we spoke to were less worried about losing their jobs than about losing the few decisions they still make during a shift. “Right now I choose the box,” one packer said. “I'd like to keep choosing something.”
