MINIROVs

The three MINI-ROVs are standard commercial Remotely Operated Vehicles (ROVs) used to meet the Navy's requirements down to a maximum depth of 1,000 feet.

The systems usually consist of the vehicle, umbilical cable, handling system, generator and operations/maintenance van. Navigation is accomplished with an ultra-short baseline acoustic tracking system. Generators can provide 120-vac power for the systems if an alternate source is not available. A handling system is available for the larger, open frame vehicle (MRII). It is a compact, folding knuckle boom crane.

The operator controls the ROVs in all six degrees of motion with auto-control functions for depth, altitude, and heading. The vehicles are equipped with a high resolution imaging sonar and have a manipulator capable of working with simple tools. They have a 35mm still camera and a color video camera. For special operations MRII can accommodate some small tools or instrument packages. The systems are air transportable and can operate from any capable platform of opportunity.
