The invention discloses a control system of a remote-controlled rescue robot. The control system of the remote-controlled rescue robot adopts a master-slave type control design, an operation end computer is a master computer, and a vehicle-mounted computer is a slave computer. A robot end bottom-layer control circuit adopts a modular design and comprises a main control unit module, a chassis driving circuit module, a telescopic main arm driving circuit module, an auxiliary arm driving circuit module, a remote controller signal receiving module and a power source module, wherein each module is arranged on a bottom-layer circuit main panel through a designed inserting pin. An operator controls the posture and the motion of a robot body through a remote controller, the master computer plays a role in image information processing and displaying, man-machine interaction and the like, the slave computer plays a role in receiving and sending control commands of an MTI inertia posture reference system, analyzing and generating bottom-layer control commands, receiving and sending the information of a sensor, and the like, and the master computer and the slave computer carry out communication work through a wireless network. The control system of the remote-controlled rescue robot is good in universality, high in transportability, flexible in construction, good in expansibility and low in cost.
