The drone has a barcode or order number display, and like Uber Eats and friends, the restaurant has an order code. The restaurant checks the drone to see what order it expects, and either hits a button to say it’s not ready yet or loads the order in and it’s done. They could theoretically have cheap touch screen tablets in them. That said, I figure they will have human supervision for the foreseeable future, at least a decade. They would basically need to be disposable for robots to make deliveries completely unsupervised. Which in turn means you could just have a human voice on a speaker, watching the robot and interacting, or you could station such humans at the restaurants themselves, to service the bots etc. for use in a known-safe, well-mapped delivery area.
