A moving robot system, employing a charging control system for robots, is configured by plural moving robots, at least one charging station and a control station. Each moving robot is designed to perform an operation thereof in accordance with programs stored therein under control of the control station. When the power of a charging-type-battery equipped in each moving robot is consumed and lowered to the predetermined level, it automatically moves to its nearest charging station designated by the control station other than the charging station which is used for another moving robot. In this case, the control station controls the moving robots such that plural moving robots are not simultaneously concentrated to one charging station.

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a charging control system by which the charging operations of the robots can be carried out efficiently.
In a first aspect of the present invention, there is provided a moving robot system employing a charging control system comprising: a plurality of moving robots each providing a charging-type-battery by which power each moving robot is moved, each moving robot being automatically moved to perform its operation in accordance with programs stored therein; at least one charging station at which each moving robot is moved to perform a charging operation when power of a charging-type-battery is lowered to a predetermined level; and control station for controlling a movement and an operation of each moving robot by communicating with each moving robot, wherein the control station controls the moving robots such that plural moving robots are not simultaneously moved to one charging station to perform the charging operation.
In a second aspect of the present invention, there is provided a charging control system for robots providing a plurality of charging stations, a control station for designating one of a plurality of charging stations and a plurality of moving robots each of which is automatically moved to a corresponding charging station by use of the power in a charging-type-battery equipped therein, wherein each moving robot provides judging means for judging whether or not a charging operation is requested for the charging-type-battery equipped in each moving robot and transmitting means for transmitting a charge request signal to the control station when the judging means judges that the charging operation is requested, while the control station provides receiving means for receiving the charge request signal, searching means for searching the nearest charging station for one moving robot within all charging stations other than the charging station designated for another moving robot and designating means for designating the nearest charging station searched by the searching means to one moving robot, so that one moving robot automatically moves to the designated charging station at which it performs a charging operation
