Underwater robot ROV is equipped with four strong thrust level to promote and two vertical / lateral thrusters, is a high-performance type ROV underwater observation. Subsection ROV to take open-frame design, easy to add a variety of tools and equipment, to adapt to different underwater tasks. Subsection ROV also give full consideration to the user later use and maintenance costs, and believe it is your economical choice. System advantages?, Light weight, portable? Strong propulsion power? Open-frame design, easy hardware upgrades? Modular components, easy to maintain? Easy-to-use control system? High-resolution zoom color camera? Lighting and camera synchronization adjustment? cruising speed adjustable? compatible with a variety of sensors and tools? maximum working depth of 300m system Summary of Benefits 1, the standard case, the system is only 25kg, light weight 2, in the wild, 1 to 2 people can laying entire system umbilical winch and integrated transport case, use and transportation is very convenient, can be equipped with sonar and underwater instruments to facilitate future upgrades without fail. And umbilical reserved transmission channel, without the need to change the expensive umbilicals 5, small size, suitable for underwater shuttle to meet the implementation of underwater photography, observation of underwater creatures and other operational requirements, easy maintenance, low maintenance costs 7, easy to learn for inexperienced operators to get started quickly, the camera and lighting synchronous, low power consumption of the propeller, but the thrust. ROV in the wild-powered easy to meet, and safe. 10, umbilical cable diameter is only 9mm, similar ROV system which smaller diameter. Convenient transport and retractable.
