In a remote control robot system including a plurality of slave arms, slave arm has a plurality of control modes of an automatic mode in which slave arm is operated based on a task program, a manual mode in which slave arm is operated based on an operator's operation received by a master device, and correctable automatic mode in which slave arm is operated based on task program while operation is sequentially corrected by the operator's operation received by master device. Operation sequence information includes an automatic part in which slave arm performs a work in the automatic mode, and a selected part in which slave arm performs a work in one selected from plurality of control modes, and the selected parts do not overlap with each other in time among the plurality of slave arms. Based on the operation sequence information, the plurality of slave arms are operated.
