Please Do Not Assault the Towering Robot That Roams Walmart

If you think shopping is tedious, try juggling 200,000 products in a Walmart. Not literally, of course, but somehow keeping the shelves stocked over an area of tens of thousands of square feet. For that you need a worker with a barcode scanner and an enviable amount of patience. Or you could unleash a hard-working robot from a company called Bossa Nova. At over six feet tall, it roams the aisles, blasting shelves with light and snapping photos.
