Robots have inhabited manufacturing plants for decades now performing tasks such as welding, painting, assembly, inspection and testing. Working side-by-side with humans, robots tackle tasks that can be performed much more efficiently or quickly by machines than humans. In some plants, the robots perform the end-to-end manufacturing process with no people involved. Both Philips and Fanuc have been able to create “lights out” peopleless plants. But what about other parts of the supply chain like warehouses? Will we ever have a “lights out” peopleless distribution center?
