The ROV Pollux III is an observation class ROV with an HD polyethylene frame, equipped with 4 electrical motors and with the following specifications:

CAMERA SYSTEM
The main ROV camera is fitted within the POD and it is installed on a dedicated support that enables a tilt angle up to 160°. The ROV system can bring to the surface 2 video signal at the same time, chosen from a maximum of 4 sources. Thus it is possible to install additional cameras and camcorders devices.

ACCESSORIES
Further to the standard video equipment, the ROV Pollux III, can be outfitted with a wide range of accessories to satisfy client requirements.
Some examples of accessories include: manipulator, sonar, HD camcorders, wall thickness gauge, CP probe and pipe tracker.

SOFTWARE
The onboard software includes the following functions and capabilities:

• auto-heading and auto-depth
• compass and depth sensor calibration
• video equalization
• On Screen Display
• clock
• data export through RS232 and USB interfaces (the exported data varies based on customer requests)

ON SCREEN DISPLAY
OSD provides the following information:

• compass reading
• depth
• auto-depth e auto-heading status
• umbilical turn counter
• time and data
• free text (at the operator disposal)
