The invention discloses a fire-fighting robot. A driving mechanism is fixedly arranged at the bottom end of a frame body, a nozzle is fixedly arranged at the top end of the frame body, a plurality oftemperature sensors are equidistantly and fixedly arranged at the top end of the frame body by taking the center of the top of end of the frame body as a base point and in the peripheral direction, awater tank is fixedly arranged in the frame body, the water tank communicates with the nozzle through a water pump, a wireless transmitter and a lifting mechanism are fixedly arranged in the frame body, the lifting mechanism is located below the water tank, and an outline of the nozzle is a round table, and the upper and lower bottom faces of the round table penetrate through each other. The wireless transmitter receives signals of a terminal such as a mobile phone, the temperature sensors start to detect the temperature in real time and feed detection values to a controller, the controller controls the driving mechanism to advance, the controller calculates difference values of the symmetrical temperature sensors in real time so that an ignition point position can be known accurately, a lifting motor lifts the water tank upwards, the controller controls the water pump to start to pump water and perform fire-fighting by aligning the upper portion, and the accuracy of the fire-fightingis improved.
