The method of claim 1 , wherein when a door of the elevator carrying the at least one robot is opened and the getting on of the at least one robot on the elevator carrying the at least one robot or a getting off of the at least one robot from the elevator carrying the at least one robot is performed, the internal user interface is configured to have a door close button deactivated so that a user who has gotten on the elevator carrying the at least one robot is unable to forcedly close the door of the elevator carrying the at least one robot.

11 . The method of claim 1 , further comprising setting a state of the elevator to be summoned as a full state when it is determined that a space sufficient for the at least one robot to get on the elevator to be summoned is not present,

wherein the state of the elevator to be summoned set in the full state is set as a summons-impossible state.

12 . The method of claim 11 , wherein:

the internal user interface of the elevator to be summoned is configured to output an indicator indicative of the full state,

the indicator is output, until a user or the at least one robot in the elevator to be summoned gets off the elevator to be summoned and the sufficient space is secured, and

the state of the elevator to be summoned is set as a summons-possible state when the sufficient space is secured.

13 . A non-transitory computer-readable recording medium storing a program to perform the method according to claim 1 .

14 . A method, performed by a computer system, of controlling at least one elevator for at least one robot passenger, comprising:

receiving a summons from a robot control system controlling the robot;

selecting an elevator to be summoned to a floor indicated by the summons;

controlling the selected elevator to move to the floor indicated by the summons;

receiving a cancellation of the summons on the selected elevator from the robot control system when a given number or more of users or robots are present in a waiting space for getting on the selected elevator;

selecting another elevator to be summoned to the floor indicated by the summons;

controlling the another elevator to move to the floor indicated by the summons;

detecting that at least one robot providing a service on at least one of floors within a building has gotten on the selected elevator or the another elevator; and

controlling the selected elevator or the another elevator carrying the at least one robot to move to a floor where the at least one robot is to provide the service,

wherein at least one of an internal user interface and an external user interface of the elevator carrying the at least one robot is configured to indicate whether the at least one robot is using the elevator carrying the at least one robot.

15 . A method, performed by a computer system, of controlling at least one elevator for at least one robot passenger, comprising:
