companies of DJ® automatic underwater ROV,towed sonar,imaging sonar, hydrophone, tide gauges,autopiloter, batteries! suppliers of best price DJ® high definition acoustic imager with camera for underwater robotics,unmanned boats in china.

autonomous underwater vehicle is a series of products for enviromental exploration. With novel proplusion system, high resolution acoustic imaging system, and high precision navigation and trajectory control system, it can be applied to pipeline track/inspection, topographic mapping, underwater archaeology, target searching, and maritime security. adopting the modularity and integration designment, the autonomous underwater vehicle can be easily change and expand modular to adapt for the different application. the most components of the autonomous underwater vehicle such as synchronous deconcentrator, autopiloter, acoustic imaging module etc., are all independent intellectual property.

remotely operated vehicle for the sea robot developed and produced with independent intellectual property rights of high tech equipment, This type of submersible can partially or completely replace the divers to complete a lot of underwater tasks, and can be completed with tasks independently in complex terrain, or cooperate with other equipment for underwater observation. It can be used for underwater search and underwater observation in shallow water area.

we can customize the underwater towing system according to the customers' requirements, provide a full set of underwater towing system products to meet the needs of the users, and customize the components of the underwater towing system to provide the platform for the user's core equipment, Of the power supply, communications, physical installation interface requirements, so that it can work to play a stable performance.

underwater towing system mainly includes: underwater drag body, towing cable, slip ring, winch and master control equipment, according to the actual requirements，it can also be installed underwater acoustic positioning system, underwater Drag body retractable devices and towing cable accessories and other equipment.

autopiloter is a core control unit designed for autonomous underwater vehicle development. The product is the "brain" of the autonomous underwater robot to realize the functions of path planning, energy monitoring, motion control, autonomous navigation, fault diagnosis, equipment information collection and execution. the product supports the autonomous underwater robot to realize the centralized and the distributed control system structure, has the widespread adaptability.

Energy system is the core unit of underwater robot, which provides power for the control, sensing and propulsion of underwater robot. Energy system uses a high reliability, high specific energy of the secondary lithium-ion battery as the core unit, and with a dedicated energy management system. The product has high security, convenient charging and discharging, switching power supply operation is simple and so on, and the size, capacity and other parameters can be customized according to user needs.

underwater drag body dragged by towing the platform from the drag, when towing, in the hydrodynamic, gravity and buoyancy under the combined effect of maintaining the ideal towing posture and drag position, through its load sensors and functional components to complete the corresponding function. At the same time, through the underwater towing cable can also drag the cable to maintain the ideal posture or shape, by dragging the cable carrying sensors and functional components to complete the corresponding functions, such as the depth of the device and the expander belongs to this type of underwater drag body.
