  Underwater marine inspections for ship hull or marine debris, etc. are one of
the vital measures carried out to ensure the safety of marine structures and
underwater species. This work details the design, development and qualification
of a compact and economical observation class Remotely Operated Vehicle (ROV)
prototype, intended for carrying out scientific research in shallow-waters. The
ROV has a real-time processor and controller onboard, which synchronizes the
movement of the vehicle based on the commands from the surface station. The
vehicle piloting is done using the onboard Raspberry pi camera and the support
of some navigation sensors like Global Positioning System (GPS), inertial,
temperature, depth and pressure. This prototype of ROV is a compact unit built
using a limited number of components and is suitable for underwater inspection
using a single camera. The developed ROV is initially tested in a pool.
