Robots are now serving customers all over the Cincinnati/Northern Kentucky Airport. The autonomous delivery robots are called Ottobots, and they bring drinks, snacks, sandwiches, and even new sets of AirPods to customers who order on their mobile phones and wait for the robots to bring them their purchases right at the gates.  The company that makes the robots, Ottonomy, equips them with 3D laser scanners, seven cameras, and safety sensors. They can travel in both indoor and outdoor environments. Someday soon you'll be able to order your next preflight snack from a robot in an airport near you.
