The invention discloses a wireless-sensor-network-based remote control rescue robot system, which comprises a ZigBee wireless sensor node, a mobile robot platform and a robot remote control operation device. The ZigBee wireless sensor node comprises a controller, an environment monitoring sensor interface, a working indicator lamp, a radio frequency module and a power module. The mobile robot platform comprises a controller, a six-wheel mobile base plate, a camera module, a wireless audio and video transmission module, a node releasing module, a wireless communication module, a high-power motor driving module and a power module. The robot remote control operation device comprises a controller, a rocker handle module, a video management module, a wireless communication module and a power module. The system adopts the six-wheel robot base plate so as to move fast, is adapted to various complex terrains and has a damping device. A robot is relatively lower, and can fully utilize a space with relatively higher visibility in the vicinity of the ground. Wireless communication is performed by utilizing a ZigBee protocol, so the system is reliable in communication, wide in range and low in energy consumption.
