Underwater snakelike robot

Abstract

The invention discloses an underwater snakelike robot. The underwater snakelike robot is composed of a plurality of modules, a waterproof protective jacket is wrapped on the outer surfaces of the modules, and the modules are fixedly connected with one another; each module comprises a body and connection portions, wherein each body can deflect in multiple directions, and the corresponding connection portions are arranged at the two ends of each body; each body comprises a plurality of hollow rings which are respectively provided with four movable connection points, two opposite movable connection points of each hollow ring are arranged on the upper surface of the corresponding hollow ring, the other two movable connection points of each hollow ring are arranged on the lower surface of the corresponding hollow ring, and every two adjacent hollow rings are movably connected through the corresponding movable connection points. The modules of the underwater snakelike robot can deflect in the multiple directions, so that the underwater snakelike robot is more flexible during operation; the waterproof protective jacket is wrapped on the modules in whole, and therefore the service life of the underwater snakelike robot can be prolonged effectively while the waterproof function is achieved.

Description

technical field [0001] The invention relates to a robot structure, in particular to an underwater snake robot. Background technique [0002] Snake robot has become a research hotspot in recent years because of its high environmental adaptability. In field detection and reconnaissance tasks, snake-like robots are required to have the ability to move in water, so underwater snake-like robots have long-term application value and research significance. [0003] In the prior art, an amphibious snake-like robot disclosed in Chinese Patent No. 200810229974.1, which involves underwater snake-like robots, is composed of multiple modules, and each module can be Relatively rotationally connected, one of the two adjacent modules can move horizontally and pitch relative to the other, and each module is composed of two electric motors, reduction gears and bevel gears, and each module has two degrees of freedom. However, the single module of the above-mentioned amphibious robot is rigid ...

AI Technical Summary

Problems solved by technology

However, the single module of the above-mentioned amphibious robot is rigid and cannot be bent. Although it can swim freely in the water, because the single module is relatively long, it cannot achieve soft and flexible movement.
