[2016 inventory] Little-known "black technology" underwater robot

Since ancient times, mankind has been committed to the exploration of the underwater world. From the mysterious and cool military submarine to the high-tech underwater robot, the undersea industrial revolution has been quietly proceeding. In recent days, the U.S. unmanned submarine incident further opened the veil of underwater robots. So what is this unmanned submarine?

Unmanned submersibles are also called "submersible robots" or "underwater robots." You can think of them as underwater drones, which are divided between military and civilian use. According to the way of manipulation, it can be divided into remote control type (ROV) and autonomous type (AUV). The ROV is on the host ship and is continuously controlled by the operator. The AUV can be programmed to navigate to one or more of the waypoints, with its own power, without cables. In 2014, the US military searched for the "tuna" (pictured below) belonging to the remains of the MAH Airliner. It belongs to AUV.

However, these two types of UUVs will also involve six technologies including bionics, intelligent control, underwater target detection and recognition, underwater navigation (positioning), communications, and energy systems. Therefore, an underwater robot is a highly technical and systematic project with a high threshold. Therefore, it has also remained in the military industry, and consumer-grade products have only appeared in recent years.

To a certain extent, it is more difficult for the “five oceans to catch plunder” than to “launch the moon in the last nine days.” Because the underwater robot wants to go underwater, the first thing that needs to be solved is the problem of the robot “surviving” underwater, and its hardware. There are very high standards. In addition to keeping the machine closed, it is also necessary to prevent corrosion and water pressure. In addition, if the robot can play underwater under balance, it needs to keep its center of gravity in the same position as the buoyancy.

What directly affects the robot's intelligence level is its control technology—the brain's brain and nerve center system. It is the integration of various artificial intelligence technologies and control technologies. After the robot detects and identifies the target underwater, it can make effective resource management and feedback.

Currently, most of the underwater robots we see on the market are only the combination of “machine” and “electricity”. It is an electromechanical system and can only be called “underwater intelligent machine” and not “underwater intelligent robot”. However, with the development of deep learning technology, the intelligence of underwater robots is constantly improving.
