The invention relates to the field of robots, in particular to a pipeline robot. The pipeline robot comprises a robot body which is provided with a working table used for working in a pipeline; the pipeline robot further comprises wheels arranged on the pipeline robot body, right angle wheel axles connected with the wheels and a rotating mechanism arranged between the right angle wheel axles and the pipeline robot body, each right angle wheel axle comprises the first wheel axle and the second wheel axle which are perpendicular to each other, and the first wheel axles are connected with the rotating mechanism. By designing the pipeline robot, according to the characteristic that the pipeline is a hollow cylinder, the wheels are arranged in a plane mode at the two ends furthest from the pipeline, and stable moving is achieved; meanwhile, the pipeline robot is controlled to move in the pipeline through the rotating mechanism, and the pipeline robot can move stably in the bending part of the pipeline; a multi-point contact mode of a traditional space multi-wheel structure is changed, the moving efficiency in the pipeline is improved, and the possibility of damage to the pipeline is decreased.
