ABSTRACT:
A plurality of mobile robots forming part of a travel control system are controlled by a travel control station. The travel control station directs each of the mobile robots to a destination where it performs selected operations. The robot, in response to instructions from the travel control station, searches the route selected by the travel control station and sends the results of the search to the control station. The travel control station, upon receipt of this information, determines whether or not the travel path searched by the mobile robot is already reserved by another other mobile robot as indicated by data stored in a reservation table. If the path is available, the control station transmits a reservation completion signal to the mobile robot. The mobile robot then travels automatically along the reserved travel path. In addition, when the travel of a given mobile robot is interfered with by other mobile robots, the travel control station directs the given robot to wait or to take an alternate route according to the situation, or directs the interfering mobile robots to halt their travel.
