“The automation of Amazon facilities is approaching a new milestone: There will soon be as many robots as humans. The e-commerce giant, which has spent years automating tasks previously done by humans in its facilities, has deployed more than one million robots in those workplaces, Amazon said. Company warehouses buzz with metallic arms plucking items from shelves and wheeled droids that motor around the floors ferrying the goods for packaging. In other corners, automated systems help sort the items, which other robots assist in packaging for shipment. One of Amazon’s newer robots, called Vulcan, has a sense of touch that enables it to pick items from numerous shelves.
