Novel tools and techniques for the automated tracking of services performed on machines by service robots, technicians, and other devices are provided. A system includes a robot fingerprint reader, service tool, and robot fingerprint database. The robot fingerprint reader may be associated with a machine receiving service and configured to receive a robot fingerprint from the service tool. The service tool may be associated with the device performing the service, and include an interface that is configured to allow the robot fingerprint to be obtained by the robot fingerprint reader. The service robot may be configured to register the robot fingerprint with the robot fingerprint database, and the robot fingerprint database may be configured to create an entry associated with the robot fingerprint of the device performing the service.

A method for controlling a serving robot is provided. The method includes the steps of: generating at least one character on the basis of at least one property related to a voice, and determining a character to be applied to a serving robot from among the at least one generated character; and generating at least one piece of visual information corresponding to the determined character, and determining a piece of visual information to be applied to the serving robot from among the at least one generated piece of visual information.

A robot and a method for controlling a robot are provided. The method includes: acquiring an image of a user; acquiring, by analyzing the image, a first information regarding a position of the user and a gaze direction of the user; acquiring, based on an image capturing position associated with the image and an image capturing direction associated with the image, matching information for matching the first information with a map corresponding to an environment in which the robot is operated; acquiring, based on the matching information and the first information, second information regarding the position of the user on the map and the gaze direction of the user on the map; and identifying an object corresponding to the gaze direction of the user on the map by inputting the second information into an artificial intelligence model trained to identify an object on the map.
