Generally, as these vehicles contain dedicated sensors,
controllers, actuators and remote control systems they are
expensive enough to be used by large companies that afford
them. The authors succeeded in devising a configuration based
on off-the-shelf components, thus drastically reducing the
building costs for similar performances.
The developed ROV is meant to be used mainly for inspection of
the vessel’s hull and for emergency applications in shallow
waters, port basins or lakes) replacing in these situations the need
of divers.

New formulations using a combination of enzymes (three
different proteases) and ionic liquids are proposed for the
removal of proteinaceous varnish layers (egg white, animal
glue, isinglass and casein). The treatment was applied on
documented reconstruction of painted surfaces and gold leaf
gilding. The use of ionic liquids (ILs) defined as “green
Description solvents” as an alternative solvent to enzymes is an area in
conservation science with a large number of possibilities: the
ionic liquid is a material that can be designed (cation-anion
combinations) to adjust to different requirements such as
improvement of enzyme cleaning effectiveness, surface
compatibility, and safety for the user.
To monitor and analyze the effectiveness of each
formulation, a novel multi-scale non-invasive approach based
