The Vehicle of WM ROV-300H is equipped with 7 high-power thrusters, four mounted horizontally, and three mounted vertically. Four horizontal thrusters can enable the underwater WM ROV to advance at a speed of up to 3.0 knots, and three vertical thrusters can enable the underwater WM ROV to have a load capacity of more than 30 kilograms underwater, ensuring that the WM ROV 300H can operate in relatively complex environments - stable operation undersea conditions.

WM ROV-300H adopts a frame design, and the main body is made of 316L stainless steel and polypropylene materials, it has strong corrosion resistance and anti-collision capabilities and is suitable for working in seawater with harsh environments. The modular design makes WM- ROV-300H repair and maintenance very simple. The WM ROV-300H can be equipped with a 4-func- tion electro-hydraulic hybrid manipulator as standard. The manipulator can simultaneously carry a maximum cutting capacity of 25mm polyethylene rope. It also has a replaceable claw function to adapt to objects of different diameters. At the same time, the strong hydraulic performance ensures the overall maximum carrying weight of the robot exceeds 20kg.

The WM ROV-300H is equipped with a push-position navigator composed of a Doppler log and high-precision inertial navigation, which effectively ensures that the robot's heading is not affected by the ferromagnetic environment of the use environment, and at the same time achieves stable positioning function in complex sea conditions, giving operators Provides precise navigation and comfortable operating experience.
