“Amazon‘s robot army is finally falling into place,” writes The Wall Street Journal (Nov. 20, 2014). The Seattle online retailer has outfitted several U.S. warehouses with squat, orange, wheeled Kiva robots that move stocked shelves to workers, instead of having employees seek items amid long aisles of merchandise. At a 1.2-million-square-foot warehouse in Tracy, Calif., Amazon just replaced 4 floors of fixed shelving with the robots. Now, “pickers” at the facility stand in one place and wait for robots to bring 4-foot-by-6-foot shelving units to them, sparing them what amounted to as much as 20 miles a day of walking through the warehouse. Employees at robot-equipped warehouses are expected to pick and scan at least 300 items an hour, compared with 100 under the old system.
In May, Amazon said it planned to deploy 10,000 Kiva robots by year-end, up from 1,400 at the time. At the heart of the robot rollout is Amazon’s relentless drive to compete with the immediacy of shopping at brick-and-mortar retailers by improving the efficiency of its logistics. If Amazon can shrink the time it takes to sort and pack goods at its 80 U.S. warehouses, it can guarantee same-day or overnight delivery for more products to more customers. The robots could also help Amazon save $400 million to $900 million a year in fulfillment costs by reducing the number of times a product is “touched.” The robots may pare 20% to 40% from the average $3.50-to-$3.75 cost of sorting, picking and boxing an order.
