    Abstract: 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.
