1. A mobile robot in a transport system including a server device configured to exchange information with a plurality of the 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, wherein the mobile robot is configured to
receive first transmission information transmitted from the server device to manage the mobile robot in a state where wireless communication with the server device is possible, and
directly execute wireless communication with another mobile robot among the mobile robots and execute a reception process of receiving the first transmission information transmitted from the server device to manage the mobile robot from the other mobile robot in a case where wireless communication with the server device is not possible;
wherein the mobile robot is configured to:
receive 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,
directly execute wireless communication with the other mobile robot and execute 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,
receive 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
directly execute wireless communication with the other mobile robot and execute 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; and
wherein:
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.
