  • Publication number: 20220197275
    Abstract: A transport system transports a transported object using an autonomously moveable mobile robot. The transport system stores management information including a use start time, a use end time, and a use location for each equipment to be lent that is transported as the transported object by the mobile robot. The transport system executes a determination process for determining whether an interval from the use end time to a next use start time is equal to or longer than a predetermined time for each equipment based on the management information. The transport system transports the equipment to its storage location after an end of use of the equipment when the interval is equal to or longer than the predetermined time, and transports the equipment to a next use location of the equipment after the end of the use of the equipment when the interval is shorter than the predetermined time.
