Maybe if your product is simple. However like Amazon's warehouses those where I work do not have consistent packaging or can they. Then toss in having packages which can be broken as customers do not always need complete sets; you do want your customer's happy don't you? The stock oh, nearly a hundred thousand items in each warehouse and do you see where robots don't fit in?

What you do do is arrange inventory based on sales, size, and packaging. Looking to minimize the travel of each picker and reduce the chance of injury. You also install conveyors and similar to make moving inventory around simpler.
