How many robots does it take to run a grocery store?

From Tom Scott.

In Ocado’s grocery warehouses, thousands of mechanical boxes move on the Hive. Are they all individual robots? Or is this one giant hive mind? • Thanks to Ocado: https://www.ocadogroup.com/technology/technology-pioneers (this video is not sponsored, and they had no editorial control).
