ROVs have gradually replaced divers and become the mainstream of underwater operations. Remotely controlled underwater vehicles: Also known as ROVs (remotely operated vehicles), they rely on a tether with copper wires or fiber optic bundles inside to connect to working research vessels on the sea to provide underwater robot motion required power, transmit control commands, and send back information gathered under the sea.Autonomous underwater gliders are the deformation of autonomous underwater robots. Underwater robots can be divided into two types: remote-controlled underwater robots and autonomous underwater robots.Working at these deep-sea levels, combined with the high risks of using oil and gas, means many tasks are done autonomously, with ROVs, autonomous underwater vehicles (AUVs), and robotics leading the way. Or stay in specific areas of the deep sea such as ridges and trenches for a long time to collect and detect data. With the assistance of high technology, scientists have designed underwater robots that can overcome the high pressure and dark environment, and help humans to complete tasks in and out of the deep sea. This force is similar to atmospheric pressure on the ground, but because water is much denser than air, it increases by about 1 atmosphere for every 10-meter increase in water depth in seawater. In the deep ocean, devastating pressure restricts everything that enters it. In addition, the deep sea is extremely cold, and the temperature in the water at a depth of 500 meters is usually only 4 to 6 degrees Celsius. The ocean also engulfs other types of electromagnetic radiation besides light, including radio signals. Because seawater absorbs and scatters light, particles suspended in seawater also scatter light, making the deep ocean dark. Uncharted Ocean Territories:ĭue to the limitations of darkness, cold and high pressure, most of the deep-sea areas are unexplored by humans. To meet the needs of developing oceans and sustainable oceans, underwater robots have become an important tool for exploring the unknown deep sea, and it is also the goal of competition and research and development among advanced countries in the world. Even today, in the face of energy catastrophe, the detection and exploitation of new energy also need to rely on Sufficient deep-sea exploration capability. Or inspection of submarine pipelines, underwater structures, submarine cables, oil drilling Underwater facilities such as platforms and harbors, and military operations have greatly reduced the risks faced by personnel when performing these tasks.Įxploring the deep sea can help humans analyze the evolution process of the earth and life, discover new biological species, and understand how biological groups survive in extremely dangerous environments. With the advancement of technology, these dangerous tasks have gradually been transferred to underwater robots, including oil extraction, submarine mineral exploration, underwater search, and salvage operations. These divers must risk dangerous dives into the deep sea to perform repairs, inspections, and even salvage tasks. Before the development of robots to explore the ocean, submarine pipelines and cables must be repaired when they are damaged or broken, or when the infrastructure of oil rigs and harbor terminals under the sea is checked for safety and stability, divers were relied on.
