Abstract: A pipeline robot capable of steering actively comprises at least two driving knuckles and at least one steering knuckle. Every two adjacent driving knuckles are connected by the steering knuckle. A front end cover is fixed on the front end surface of the driving knuckle at the most front end. A sensor is mounted in the center of the front end cover. A rear end cover is fixed on the rear end surface of the driving knuckle at the rearmost end. A universal spherical hinge is arranged in the center of the rear end cover. Each driving knuckle comprises a main frame, driving mechanisms and telescopic mechanisms; the telescopic mechanisms are mounted in the main frame, and capable of causing contraction of the driving mechanisms into the main frame. The steering knuckle can drive the front driving knuckle connected thereto to steer.
