A robot places pizzas into an oven as it comes off a conveyer belt at Zume Pizza in Mountain View, Calif., Wednesday, Aug. 24, 2016.  Zume Pizza uses robots to make customers&#039; pizza, hoping to reduce labor costs and therefore make pizza a more profitable venture. One robot spreads the sauce on the uncooked pies, then humans add toppings, and another robot pops it in the oven. They are also hoping to use delivery trucks with smart ovens to cook pies en route to customers. (Patrick Tehan/Bay Area News Group)
