Building bots interfacing with security systems

A method, comprising:

• receiving by a server or access control system a message from an autonomous mobile unmanned machine, which is a request by the autonomous mobile unmanned machine for access through a door;
• determining whether the autonomous mobile unmanned machine is authorized to gain access through the door, and if so
• sending a message to the access control system to cause electronic locks on the door to unlock the door;
• receiving a message indicating that a tailgating user is present;
• and
• causing by the autonomous mobile unmanned machine, the autonomous mobile unmanned machine to enter a manual operation mode where movement of the autonomous mobile unmanned machine is controlled manually by a user in response to the reception of the message indicating that the tailgating user is present.

An autonomous mobile unmanned machine comprises:

• a computer carried by the autonomous mobile unmanned machine to control passage of the autonomous mobile unmanned machine;
• at least one sensor carried by the autonomous mobile unmanned machine, with the computer configured to cause the autonomous mobile unmanned machine to:
• receive by the autonomous mobile unmanned machine a beacon signal emanating from a beacon, wherein the beacon is deployed in proximity to a first one of one or more doors in a facility, by receiving the beacon signal by a receiver device on the autonomous mobile unmanned machine;
• determine by the autonomous mobile unmanned machine whether the autonomous mobile unmanned machine needs access through the first door;
• send a message to either a server or an access control system when the autonomous mobile unmanned machine determines that it needs access through the first door at a specified location identified by the beacon;
• receive a message from either the server or the access control system that the first door has been unlocked;
• receive a message from either the server or the access control system, the message indicating that a tailgating user is present;
• and
• enter a manual operation mode where the movement of the autonomous mobile unmanned machine is controlled manually by a user in response to the reception of the message indicating that the tailgating user is present.

An access control system, comprising:

• a computing system, configured to:
• receive from an autonomous mobile unmanned machine a message that the autonomous mobile unmanned machine needs access through a door;
• determining whether the autonomous mobile unmanned machine is authorized to gain access through the door;
• exchanging credentials with the autonomous mobile unmanned machine to cause the computing system to authenticate the autonomous mobile unmanned machine;
• receive sensor data by detecting one or more badges or other credentials or other devices indicating a presence of one or more entities in proximity to the door;
• process the sensor data and when the sensor data indicates that any of the badges detected or read in an area around the door are not authorized access through the door;
• issue an indication to the autonomous mobile unmanned machine to wait and retry at a future time;
• receive a message indicating that a tailgating user is present;
• and
• cause by the autonomous mobile unmanned machine, the autonomous mobile unmanned machine to enter a manual operation mode where movement of the autonomous mobile unmanned machine is controlled manually by a user in response to the reception of the message indicating that the tailgating user is present.
