Abstract
A hose piston is disposed inside a flexible hose which is filled with fluid and movable in any direction upon hydraulic pressure. The rollers of an external device are engaged on the exterior surface of the flexible hose and are located adjacent to the midsection of the hose piston. The fluid pressure inside the flexible hose forces the hose piston to move along a given direction within the flexible hose, which in turn forces the rollers to travel in the same direction. This mechanism can transport the external device along the flexible hose.
