A system and method for pipeline maintenance may include a payload and a transport module having the payload attached thereto. The transport module may include a plurality of movable arms each having at least one respective wheel. At least some of the wheels may be drive wheels which are operable in a first orientation to drive the transport module linearly along a length of a pipeline, and are further operable in a second orientation to drive the transport module circumferentially around an inner surface of the pipeline. At least some of the arms are operable to move the payload in a generally radial direction toward and away from an interior surface of the pipeline.
