To further enhance the AC-ROV’s ability to inspect large surfaces quickly, AC-CESS now offer a roller kit that quickly converts the AC-ROV into a four wheeled vehicle that can roll over and alternate between surfaces in different planes. • • • Reduces Inspection Time and Cost Robust, Serviceable and Fully Integrated Solution Quick and simple ‘no modification’ retrofit Cleverly engineered, the roller kit is effectively neutral in water, so there is no need to adjust vehicle ballast or buoyancy. The individual rollers slide out on their axles for track width adjustment to vary the AC-ROV standoff, or to improve tracking stability. Control and adjustment of the “stick-on” force is easy. Simply use the AC-ROV “flight freeze” function to set the suction force developed by the thrusters as the vehicle approaches a surface. If conditions change, push the flight freeze button again to simply set the suction to any new level that is seen to be more efficient. Pressing another button quickly switches the AC-ROV into the free flight mode. • • • Rollers mount to side, top or underside of AC-ROV Does not affect the AC-ROV ballast or trim Does not affect free flight of the AC-ROV The parking or skimming surface can be almost anything from absolutely flat through to rough natural rock, steel with weld runs and even curved surfaces. The unique centre-less AC-ROV thrusters are foul proof, so soft marine or weed growth is not a problem for parking, although it may inhibit skimming. The inherent stick and skim ability of the AC-ROV is applicable to surfaces overhead, underneath or side on to the vehicle, and to a lesser extent surfaces in front of or behind it. The roller option simply enhances the skimming ability and reduces wear and tear on the vehicle body. The fitting time for the roller option is less than 5 minutes and, no specialist training is required. The outcome retains the clean, robust and snag free shape of the AC-ROV and does not affect its market leading free flying mobility. All the capabilities of the standard AC-ROV are retained. The wide angle camera gives good inspection cover of any surface skimmed on the rollers, but if a different perspective of a target is required, then it is a simple operation to lift off and re-attach, or park up via a different side of the AC-ROV. The ability to alternate between free flight, roller and parking modes whilst in the water makes the AC-ROV ROLLER a hugely versatile inspection tool in open and confined spaces. This is all achievable with the standard and completely intuitive 3D hand control and fight assist functions that existing AC-ROV pilots are familiar with. • • • Ideal for Hull, Internal Pipe & Tank Inspection Easily alternates between free flight, rolling and parking modes Utilises existing and familiar controls

The above detail shows the roller units attached to the base of the AC-ROV using the 4 lower light ports. Use the top 4 light ports for fixing the rollers to the top of the AC-ROV. If the wheels are to be mounted to the side of the AC-ROV then select the light ports on that side and use 2 from the top and 2 from...
