The invention relates to an infrared detection robot. The infrared detection robot comprises a robot body, a holder, an angle sensor, an infrared detector, an industrial personal computer, a holder control system and an upper computer, wherein the holder is arranged on the robot body; the angle sensor and the infrared detector are arranged on the holder; the angle sensor is electrically connectedto the holder control system which is electrically connected to the industrial personal computer; the holder control system is also in driving connection with the holder; and the industrial personal computer is electrically connected to the infrared detector and the upper computer. The free adjustment and control of the angle of the holder are realized in the routing inspection process of the infrared detection robot, thus, the infrared detector is driven to accurately position an object to be detected, and the detection accuracy is high; the infrared detection robot can carry out large-scalerouting inspection according to the designated route under the control of the industrial personal computer and uploads test results in real time; and in addition, the test results interact with data,video, audio and other information through the upper computer, a local monitoring background and a long-distance centralized control background.
