jones_supa writes Amazon is continuing to maintain its vision of an automatic warehouse. Since acquiring robot-maker Kiva, a Massachusetts company, for $775 million in cash in 2012, the e-commerce retailer has been increasingly implementing automation at its gargantuan fulfillment centers. This holiday season, Amazon's little helper is an orange, 320-pound robot. The 15,000 robots are part of the company's high-tech effort to serve customers faster. By lifting shelves of Amazon products off the ground and speedily delivering them to employee stations, the robots dramatically reduce the manual labor to locate and carry items. The Kiva robots, which resemble overgrown Roombas, are capable of lifting as much as 750 pounds and glide across Amazon's warehouse floors by following rows of sensors. Because Kiva-equipped facilities eliminate the need for wide aisles for humans to walk down, eighth-generation centers can also hold 50% more inventory than older warehouses. As Amazon is doing well, the company says that increase of automation hasn't yet led to staff reduction.
