The invention relates to the technical field of robot inspection, in particular to an inspection robot with a detection device. The inspection robot with the detection device comprises a mobile carrier and mechanical arms arranged on the mobile carrier, wherein a camera is arranged at the front end of one mechanical arm, and the detection device is arranged in the camera. The detection device comprises an ultrasonic distance measuring sensor, a displacement sensor, an attitude detector, a pressure sensor and signal conditioning transmitters, wherein the ultrasonic distance measuring sensor, the displacement sensor and the pressure sensor are electrically connected with the attitude detector through the signal conditioning transmitters respectively, a processor is arranged in the attitude detector, and the processor is electrically connected with the mechanical arms. The situation of camera wear can be effectively reduced.
