The invention relates to a full-environment multi-information fusion intelligent detection robot system. The system comprises a robot and a monitoring terminal (17) used for monitoring and planning routes for complex environments. The robot is wireless connected with the monitoring terminal (17) and comprises a processor unit, and a navigation information acquisition unit, an environment information acquisition unit (5), a movement control unit and a WIFI communication (11), which are connected with the processor unit. The WIFI communication module (11) carries out communication connection on the processor unit and the monitoring terminal (17). Compared with the prior art, indoor and outdoor full-environment autonomous positioning navigation can be precisely achieved; indoor environment information can be precisely; and functions of map construction, obstacle avoiding and route planning are finished.
