Staff comprises some 20% of the costs of running a pizza chain. Robots, on the other hand, never get sick and never need vacations or cigarette breaks.
Robots don’t make mistakes. They don’t use ingredients that have passed their expiration dates and they never forget to wear their protective gloves. A self-contained “plug and play” robotic system can even monitor the air quality, so everything stays hygienic.
Consistency. A human worker may make a great pizza at the beginning of his or her shift, but after eight hours, a customer might get a sub-optimal pie.
