Information output method and information output device

An information output method used by an information output device, the information output method comprising:

• obtaining, from each of at least two autonomous mobile robots each providing at least one service, first information including (i) information about a location of the autonomous mobile robot and (ii) information about a service provided by the autonomous mobile robot;
• presenting, based on the first information, information about at least two services provided by the at least two autonomous mobile robots to a terminal device used by a user that receives service among the at least two services;
• obtaining, from the terminal device, second information including:
• a service providing location designated by the user to receive the service;
• and information about the service selected by the user;
• determining, based on the second information, one autonomous mobile robot providing the service selected by the user among the at least two autonomous mobile robots;
• and
• outputting, to the one autonomous mobile robot determined, first control information used for moving the one autonomous mobile robot to the service providing location,
• wherein each of the at least two autonomous mobile robots includes:
• a travel section that controls travel of the autonomous mobile robot;
• and a box section that is disposed above the travel section and used for providing the service,
• the information output method further comprises:
• obtaining log information generated as a result of an operation of the box section included in the one autonomous mobile robot;
• generating, based on the log information, second control information used for implementing a second function different from a first function of the box section included in the one autonomous mobile robot;
• and
• outputting the second control information to the one autonomous mobile robot,
• the first function is at least a part of a function that implements provision of a first service provided by the box section,
• the second function is performed together with the first function to implement provision of a second service different from the first service,
• the first control information includes a remote control signal transmitted to the one autonomous mobile robot and route information indicating a moving route to the service providing location, and
• the one autonomous mobile robot moves to the service providing location by the travel section controlling a driver based on detection results from a second imager and a sensor each mounted on the one autonomous mobile robot so as not to collide with an obstacle, while following the route information.
