The logistics support required and limited bottom time for divers exacerbated the challenges. Each mission faced uncertainty about what the divers would encounter once they were below the surface. Previous methods were time-consuming and labor-intensive, often with scarce verifcation of mission success or completion. While land response personnel beneft from the use of ground robotics, underwater response equipment operators had no alternative. Ground robot development gave the operator a means to fnd a hazard from a safe distance and take steps to mitigate or dispose of the item, all in real time. Similarly, to help protect their divers from unnecessary threats, the Navy sought out a "suitable underwater robotic platform" that could perform the hazardous initial search and reconnaissance phase and help Navy technicians locate evidence, collect, save and share data from underwater forensic evidence collection. Selecting the Pro 4 for the Navy The Navy chose the Pro 4 based on features unique to VideoRay. Engineered for reliability, ruggedness, portability and ease of use, the VideoRay Pro 4 debuted in 2009. Naval forces around the world have acquired VideoRay ROVs for port security missions, including the U.S. Navy, Coast Guard and Army. The VideoRay Pro 4 ROV is engineered for rapid deployability and low maintenance requirements. The VideoRay ROV's portability and power requirements (100 to 240 volts AC or 12 volts DC with an inverter, or a 1-kilowatt generator) allow the ROV to deploy quickly from almost anywhere, even remote areas or tight spaces. The entire Pro 4 system is North Sea-compliant and can be easily transported by hand, in the trunk of a car, by boat or in a helicopter. Routine maintenance for the Pro 4 can be done by the operator in the feld without having to send the ROV back to the factory for service. VideoRay CoPilot RI—along with the Pro 4's user interface, VideoRay Cockpit—performs autonomous target reacquisition and identifcation missions, using VideoRay 32 st / November 2013 CoPilot software by SeeByte, a Teledyne RD Instruments (Poway, California) DVL (Doppler Velocity Log), and Teledyne BlueView (Bothell, Washington) P900130 forward-looking imaging sonar. CoPilot RI provides autonomous identifcation, marking and real-time sharing of visual information of underwater threats. The software fuses data from a GPS and DVL to allow autonomous search, location, marking and saving video footage and sonar data. Operators can either map out a predefned fight path for the ROV to follow autonomously, or use point-and-click piloting en route to fy to targets of interest. CoPilot RI also offers autonomous station keeping, even in rough sea conditions and currents. The VideoRay Pro 4's data collection offered an advantage for the Navy through its compatibility with the Common Operator Interface Navy (COIN). The ROV can overlay real-time geodetic data on still images, video and sonar snippets captured during the mission, and automatically download data into COIN during the mission. COIN can then exchange data with the U.S. Navy Mine Warfare Environmental Decision Aid Library (MEDAL), as well as Mine Warfare Tactical Command Software (MINTACS), the common operating picture tool for underwater intelligence used by 15 countries. As force protection becomes increasingly globalized, VideoRay's compliance with these common interfaces benefts armed forces throughout the world. By visualizing data in a way that can be quickly understood and easily shared by multinational forces, the VideoRay Pro 4 adds to the common operational picture and expands search capability to include all available platforms, such as AUVs, side scan sonars, marine mammal systems and diver data. A single VideoRay mission can rely on data collected in real time, as well as data and underwater targets already identifed in earlier missions, no matter what tool was previously used.
