The robot follows assigned seats after seat numbers are given on a remote control and the time it takes to serve can be adjusted if the customer’s in a hurry. When they arrive at a specific seat, the robots turn to the customer and greet the person politely with, “Hello! Here’s your order, and please enjoy yourself.” Then, after the guests get their food from the tray, the machines say, “Please touch my head if you don’t need anything else.” When the customer gives a pat on their heads, the robots automatically head for another guest.
The robots run along photosensitive strips on the ground. They can carry trays of food, greet customers and even communicate through a series of simple phrases. With optical or magnetic sensors the robots are able to know exactly where to stop in the restaurant, returning to the kitchen when the food is delivered.
