Towed multi beam fish robot is equipped with 4 horizontal thrusters, 2 vertical / lateral thruster. Streamlined design,its carrying fish sonar and camera equipment, lighting.Remote control, operating water depth of 300m, the ship is equipped with a deck control unit and a power supply unit,used for power supply system, data communication and system control.

The system has the advantages of:

1, bionics design idea, can speak and fish Sonar on thedepth of observation of the most suitable, meet the needs of the fish and underwater photography research.

2, in the low flow conditions, can be carried out underwatercruise operations like ordinary robot

3, also can survey ship towed observation, the fastestspeed is 5 - 6 section drag, depth can be controlled in therange of 50 - 100 meters, very suitable for reservoir fish surveys, deep water basin. To improve the efficiency of fish resource investigation.

4, fiber optic umbilical cable, equipped with a manual winch,transportation is very convenient
