The invention relates to a fire-fighting robot co-location, reconnaissance, fire source recognition and aimed fire extinguishing method. A positioning method is adopted for carrying out real-time positioning on multiple fire-fighting robots, the positions of the robots relative to a control table are rapidly obtained, and a robot backstepping space can be conveniently positioned, controlled and managed; a reconnaissance robot and the fire-fighting robots are adopted for cooperative work, through the reconnaissance robot, the space positions of the interest points like a fire source can be obtained in the front, space coordinate conversion is carried out to achieve precise fixed-point fire extinguishing of the fire-fighting robots, and when the target points such as the fire source are recognized, influences of barriers like water cannon flows are avoided, the robot positioning, reconnaissance, and fire extinguishing method is not affected by any indoor or outdoor environment, the application range is wider, through real-time rapid positioning, reconnaissance, and fire extinguishing, the full-automatic recognizing, positioning and fire-extinguishing robot automatic aiming functionsof the dangerous sources such as the disaster site fir source can be achieved, the site disposal speed is improved, the dangerous source treatment efficiency is improved, and the personal damage and financial losses are reduced.
