1. Planning of underwater robot
The planning of underwater vehicle is an important link in the application, and it is necessary to make a comprehensive planning of the robot's performance index, structure form and task according to the actual demand and working environment. In the planning process, it is necessary to consider the key factors such as the stability, mobility, operation accuracy and reliability of the robot to ensure that the underwater robot can meet the needs of practical applications.
2. Sensor technology
Among the many sensors, sonar, cameras and pressure sensors are the most commonly used. Sonar is a sensor that uses the characteristics of sound waves to detect and communicate underwater. It is mainly used in the underwater robot for obstacle detection, terrain mapping and target tracking. With sonar, underwater robots can sense objects in their surroundings and determine their location and distance. The advantage of sonar is that it can work in a variety of underwater environments and is not affected by light and line of sight. Cameras are another commonly used sensor, mainly used for image acquisition and target recognition. Through the camera, the underwater robot can obtain a clear image of the underwater environment, and use image processing technology for target detection, classification and recognition. It is of great significance for underwater archaeology, Marine biology research and seabed resource exploration. Pressure sensors are sensors used to measure water pressure and are essential for depth control and navigation of underwater vehicles. Through the pressure sensor, the underwater robot can sense its depth and position in real time, and make corresponding adjustments and controls. This is very important to ensure the safety and stability of the underwater vehicle.
3. Environmental information collection
The underwater robot needs the ability to collect environmental information in order to comprehensively understand and analyze the underwater environment. In the application, it is necessary to use a variety of sensors and measurement technologies, such as sonar, optical imaging, water temperature, salinity and other measurement technologies, to achieve a comprehensive perception and measurement of the underwater environment. At the same time, it is necessary to adopt advanced data processing and analysis technology to process, analyze and fuse the collected environmental information to achieve an accurate understanding and description of the underwater environment.
4. Navigation control technology
Navigation control technology, as one of the key technologies of underwater vehicle, plays a crucial role in the positioning and navigation of the robot. The underwater environment is complex and changeable, and the navigation control technology is highly required. In order to ensure that the robot can accurately position and stably navigate underwater, advanced navigation control technology must be adopted. Inertial navigation is a navigation method based on the principle of kinematics, which calculates the position and attitude of the robot through the movement information, does not rely on external information sources, and can navigate autonomously under water for a long time. GPS navigation is a navigation method based on global positioning system. In surface or near-surface environments, GPS signals are generally stable and can provide high positioning accuracy. Sonar navigation uses the propagation characteristics of sound waves in water to locate and navigate. The sonar device sends out acoustic signals to the surrounding area and reflects them back after encountering obstacles or undersea terrain. By analyzing the time and intensity of the reflected signals, the distance and orientation between the robot and the obstacles or undersea terrain can be determined. Sonar navigation is one of the common navigation methods of underwater robot because of its high positioning accuracy and stability.
5. Remote control and autonomous mode selection
The underwater robot can choose the remote control mode or the autonomous mode to operate according to the actual needs. In the remote control mode, the operator directly controls the robot through the remote control system; In autonomous mode, the robot completes the task autonomously according to a preset program or intelligent algorithm. Choosing the right operation mode can improve the operation efficiency and reduce the labor cost.
ROV buoy is an important part of ROV. Its main function is to provide the ROV with buoyancy in water, so that it can be stably suspended underwater, and facilitate various detection and operation tasks. The design and manufacture of ROV buoys need to take into account factors such as the working environment, working depth, and load requirements to ensure the stability and safety of the ROV underwater.
