The invention discloses an intelligent early warning and fire extinguishing robot. The intelligent early warning and fire extinguishing robot is formed in the mode that a temperature sensor, a smoke sensor, a flame sensor, a pan-and-tilt camera, a two-freedom-degree mechanical arm, a fire extinguisher and a controller are installed on a wheel type vehicle, the two-freedom-degree mechanical arm is installed on the side of the fire extinguisher in a surrounding mode, and the temperature sensor, the smoke sensor, the flame sensor, the pan-and-tilt camera, the two-freedom-degree mechanical arm are connected with the controller in an electric loop mode. The intelligent early warning and fire extinguishing robot is high in anti-interference ability, good in space applicability, capable of monitoring fire flame videos of a tiny fire source at the beginning of a fire, high in fire early warning accurate and low in false alarm rate.
