[0050] When there is no need to go deep into the fire scene to investigate the situation, the robot body 1 can be arranged to patrol or stay outside the fire scene. At this time, the control warning light 74 is turned on and the loudspeaker 76 continuously plays a reminder voice to remind irrelevant personnel at the scene to pay attention to safety and stay away from the scene.
