A method of controlling an elevator for a robot passenger includes detecting that at least one robot providing a service on at least one of the floors within a building has gotten on an elevator moving through the floors; controlling the elevator to move to a floor where the robot is to provide the service; and indicating whether the robot is using the elevator on at least one of an internal user interface and an external user interface of the elevator. The external user interface is configured to indicate that the elevator is being used as a dedicated elevator for the robot, and to disable at least one of indicators indicating whether the elevator is going up or down, the current location of the elevator, and a floor where the elevator is scheduled to stop, when the elevator is being used as a dedicated elevator for the robot.

In an elevator installation, an elevator control system is configured to receive an elevator call from a person via a call terminal and from a robot via a radio transceiver. A current transport capacity of the elevator installation is determined. An elevator call originating from the robot is recognized by the elevator control system, the call including a priority level set by a dispatcher, wherein the priority level is one of a high, a medium and a low priority range, wherein the elevator call is indicative of a boarding floor. The allocation of the elevator call originating from the robot to the elevator car is delayed if the priority level is set to the medium priority range and the current transport capacity is lower than a first threshold value, or if the priority level is set to the low priority range and the current transport capacity is lower than a second threshold value.
