Claim 11:
12. A non-transitory computer-readable medium storing a program causing a server computer to execute a management process in a transport system including the server computer configured to exchange information with a plurality of mobile robots that is autonomously movable inside a facility by wireless communication and manage the mobile robots and transporting a transport object by using the mobile robots, the program causing the server computer to execute:
causing the mobile robot to receive first transmission information transmitted from the server computer to manage the mobile robot and second transmission information transmitted from the server computer to manage another mobile robot among the mobile robots in a state where wireless communication with the server computer is possible;
causing the other mobile robot to receive the first transmission information and the second transmission information in a state where wireless communication with the server computer is possible;
causing the mobile robot to directly execute wireless communication with the other mobile robot, receive the first transmission information from the other mobile robot, and execute a first communication process of transmitting first positional information indicating a position of the mobile robot to the other mobile robot in a case where wireless communication with the server computer is not possible;
causing the other mobile robot to directly execute wireless communication with the mobile robot, receive the second transmission information from the mobile robot, and execute a second communication process of transmitting second positional information indicating a position of the other mobile robot to the mobile robot in a case where wireless communication with the server computer is not possible; and
the management process includes
receiving the first positional information received in the first communication process by the other mobile robot from the other mobile robot in a state where wireless communication with the other mobile robot is possible,
receiving the second positional information received in the second communication process by the mobile robot from the mobile robot in a state where wireless communication with the mobile robot is possible,
executing searching for the mobile robot based on the first positional information in a case where wireless communication with the mobile robot is not possible, and
executing searching for the other mobile robot based on the second positional information in a case where wireless communication with the other mobile robot is not possible;, wherein the communication process includes:
receiving the first transmission information and second transmission information transmitted from the server device to manage the other mobile robot in a state where wireless communication with the server device is possible, and
executing a transmission process of transmitting the second transmission information to the other mobile robot in a case where wireless communication of the other mobile robot with the server device is not possible;, wherein:
the transmission process is executed in a case where the server device shuts down;
the second transmission information transmitted in the transmission process is information received from the server device before the server device shuts down;
the reception process is executed in a case where the server device shuts down; and
the first transmission information received in the reception process is information received by the other mobile robot from the server device before the server device shuts down.
