Coelacanth-imitating underwater robot

Abstract

A coelacanth-like underwater robot disclosed by the present invention is characterized in that it includes a fish-like cavity and a control module, a caudal fin drive module, a pectoral fin auxiliary module, a buoyancy adjustment module and a center of gravity adjustment module respectively arranged in the cavity ; wherein: the caudal fin drive module, pectoral fin auxiliary module, buoyancy adjustment module and gravity adjustment module are respectively connected with the control module, respectively control the tail fin drive module to drive the tail to bend through the pressure sensor, attitude sensor and positioning sensor of the control module, and use the curved tail to be concave-convex The pressure difference between the two sides of the liquid creates pressure to propel the robot forward. Through the above structure, the coelacanth robot of the present invention can simulate fish swimming in water, can autonomously avoid obstacles, plan routes, and realize automatic ups and downs in different water areas, thereby realizing the intelligent swimming of the robot, and its motion characteristics are relatively Compared with traditional propeller propellers, it is more efficient, quieter and stealthier.

Description

technical field [0001] The invention relates to the field of robots, in particular to an underwater robot imitating a coelacanth. Background technique [0002] The terrain in the natural waters is complex and diverse, some are jagged with strange rocks, some are frequent undercurrents, there are many caves and blind holes, and there is not enough space in many caves and blind holes for the robot to turn around. However, in order to explore the environment and biological living conditions in underwater caves and blind holes, underwater robots must enter the cave and return the same way. At present, bionic robots that imitate trevally such as bluefin tuna can move forward, turn, float and dive by using flexible tail fins, but it is difficult to realize backward cruising. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a coelacanth-like underwater robot with the advantages of high efficiency...
