Abstract: In a conveyance system, a conveyance object is conveyed by use of a plurality of mobile robots autonomously movable inside a facility. In a case where a blockade request event occurs in at least one area inside the facility, the conveyance system receives occurrence information transmitted from a facility management system configured to manage the facility and causes the mobile robots to execute an operation restriction to restrict operations of the mobile robots. In a case where a predetermined condition for the blockade request event is established after the mobile robots execute the operation restriction, the conveyance system reboots the mobile robots.

Abstract: To effectively enhance the operation efficiency of an autonomous mobile robot, an autonomous mobile robot control system includes a processor and a plurality of environmental cameras. The processor estimates a moving route of each of a plurality of moving bodies on the basis of characteristics of each of the plurality of moving bodies and sets a subset of the plurality of moving bodies whose moving routes overlap among the detected moving bodies as avoidance processing target moving bodies. The processor generates an avoidance procedure for the avoidance processing target moving bodies so the motion of the avoidance processing target moving bodies does not interfere with the motion of other avoidance target moving bodies.
