1. A pipeline inspection device for assessing a condition of a pipeline containing a liquid, the pipeline inspection device comprising:
a propulsion module configured to generate a force sufficient to move the pipeline inspection device from one side to another side along a horizontal plane and/or to move the pipeline inspection device from top to bottom along a vertical plane to maneuver the device around a pipeline feature in an intended path of the pipeline inspection device as the pipeline inspection device is displaced along a length of the pipeline by movement of the liquid in the pipeline; and
a plurality of collapsable supporting petals extending radially outward from the pipeline inspection device and around a circumference of the pipeline inspection device.
