An article management system includes a transport robot and a rack robot. The transport robot has an input interface that receives a transport request from a user, the transport request having a first request to transport a first article stored in the rack robot to the user, a first communication circuit that transmits the first request to the rack robot, and a movement that causes the transport robot to move toward the rack robot. The rack robot has a second communication circuit that receives the first request, and a conveyor that moves the first article on the first request between the rack robot and the transport robot.
