Problems solved by technology

The problem here is that, in order to meet the needs of "horizontal operations", submersibles are generally designed so that the main volume is distributed along the horizontal direction
However, for most submersibles, the increase in diving speed obtained by increasing the ballast is of limited effect due to the fact that water resistance is proportional to the square of the velocity

Abstract

The invention provides a method for changing a navigation state of an underwater robot and the underwater robot with variable navigation states. According to the method, the underwater robot can diveand float up in the vertical direction with the minimum resistance in the diving and floating processes, so that the rapid vertical movement is realized; after reaching the specified depth, a submersible main body rotates for 90 degrees by discarding the special ballast, matching with the fine-adjustment gravity center and assisting by a stabilizer, and then enters the horizontal navigation statewith the minimum resistance, so that high-efficiency cruising, observation or operation at a specified depth can be realized.

Description

technical field [0001] The present application relates to the field of underwater equipment engineering, in particular, to a method for changing the navigation attitude of an underwater robot and an underwater robot with variable navigation attitude. Background technique [0002] At present, submersibles are mainly divided into two categories: manned submersibles and unmanned submersibles. Among them, unmanned submersibles are generally called underwater robots. Manned submersibles and underwater robots are very common in related technologies, so they are generally not clearly distinguished in this field. [0003] As we all know, the working principle of a submersible is that it needs to dive to a certain depth, and then carry out underwater observation or other operations. The moving process of the submersible is therefore divided into two types: vertical movement and horizontal movement. Vertical movement includes ascending and descending, while horizontal movement incl...
