The invention discloses an SLAM-based intelligent control system for a robot. The SLAM-based intelligent control system for the robot comprises a MiniPC, an ARM embedded master controller, a laser radar sensor, a visual sensor, universal wheels, an inertia measurement unit, a ZIGBEE module, an orthogonal code disk and encoder, a camera and a 2D laser sensor, wherein the ARM embedded master controller is connected with the IGBEE module in an interactive manner and is connected with the MiniPC in an interactive manner, and the universal wheels are connected with the laser radar sensor, the ZIGBEE module, the inertia measurement unit, the orthogonal code disk and encoder and the visual sensor. When the SLAM-based intelligent control system is used, data of the inertia measurement unit, the laser radar sensor and the camera are integrated to complement the advantages of all the sensors, so that the mapping and positioning precision of a movable platform is improved, obstacle avoidance in acomplicated environment and in a place with a dense crowd and local dynamic obstacle avoidance are realized, and the robustness of a mobile chassis of the robot during actual operation is improved.
