Using the SeaPerch ROV

Safety Precautions

Safety is an essential consideration when working around water. Besides the
risk of ROV operators falling into the water, electrical safety precautions
should be observed. All ROV operators (controller and tether manager) as
well as water-side observers should exercise caution and stay aware of the
movement of others while near the edge of the pool, dock, or other water-side
location. Even simple inattention to what is going on in the area while
focused on operating an ROV can lead to unexpected "dips." Wearing a
personal flotation device is recommended if operating the ROV from a pier
that extends into deep water or from a boat (as is often required by law).
Even though the ROVs operate on low voltage direct current, it is a good idea
for people handling the ROVs' electrical controls, batteries, and related
systems to keep their body parts out of the water. Keeping the water surface
free of disturbance also makes the ROVs and their maneuvers much easier to
see.
Batteries are heavy, and if one is pulled off a tabletop by a tug on the ROV's
power cord, it can cause an injury (such as if it is dropped on a foot), as well
as damage to the battery. Be careful in placement of the battery; consider
keeping it on the ground or pool deck.

Environments Suitable for Using a SeaPerch ROV

SeaPerch ROVs can be used in fresh water or saltwater, in man-made pools
or natural marine environments. However, ballasting as well as post-
operation cleaning requirements are different for the two types of
environments.
Due to the differing water densities, adjustments to the total ballast, and thus
often to ROV's trim, are usually needed when moving from one environment
to the other.
After operations in either pool water or saltwater, the ROV should always be
rinsed thoroughly with fresh water; however, use in natural marine
environments may require biologic material or sediment to be removed as
well, even from inside the ROV's pipes.
