Interesting idea, but I don't think it works in practice.
I have foods and spices scattered across many cabinets in my kitchen - just like every other family in the world (except for a few hunter/gather families). Making them all autonomous vehicles would be expensive.
I also sometimes come in at random times and snack - the fridge with the snack I want better be there, not out to the store to be refilled. This again is a situation that every family in the world faces some variation of.
