Abstract
A camera skid and thrust nozzle assembly for supporting a camera while being positioned in a tubular pipe or conduit spaced from any wall of the conduit and permitting movement of the assembly along the conduit. The assembly includes a cage rotatably fastened to a high pressure fluid tractor nozzle, wherein the cage can rotate about an axis through the tractor nozzle. A camera support structure is fastened within the cage for rotation of the support structure about the axis independent of rotation of the cage. The camera support structure has a weight attached thereto for urging rotational orientation of the camera support structure within the cage according to a sensed external gravitational force on the assembly.
