I've been in the business long enough to know that the suppliers of these robots are going to wring their customers for every cent of recurring revenue they can. Once the kitchen is literally built around and dependent on them, they've got your nuts in a vise and they'll gleefully squeeze as hard as they can.
I imagine these things will break all the time, and have restrictive contracts on who can repair them at high dollar figures, see Mcdonalds ice cream machines X 100.
Except that the robot makers aren't stupid. As with medical equipment, they are going to make the hardware/software a subscription not a one-time payment.
