Remotely operated vehicles (ROVs) are underwater robots used for inspections as well as for recovery, cable burial, and search and rescue. Applications range from oceanography and fishing to civil engineering and security.
They provide a quick and safe means of inspection, which removes the risks associated with other methods and can save time and money.
ROVs are controlled remotely by an operator who is usually based above the surface. Communication is through an umbilical, which provides a realtime, two-way flow of information, including video footage.
Small ROVs offer greater manoeuvrability in smaller spaces or shallower waters, yet still provide detailed images.
