Small multifunctional underwater robot and working method thereof

Abstract

The invention discloses a small multifunctional underwater robot and a working method thereof. The robot comprises a shell, an electric control module, a double-propeller propelling mechanism, a buoyancy lifting mechanism, a posture adjusting mechanism and a temperature difference power generation device. The electric control module, the buoyancy lifting mechanism, the posture adjusting mechanismand the thermoelectric power generation device are located in the shell, and the double-propeller propelling mechanism is located outside the shell. The electric control module comprises an intelligent controller and a battery. The method comprises a diving and floating mode, an advancing and retreating mode, a turning mode, a gravity center adjusting mode and a temperature difference power generation mode. The buoyancy lifting mechanism works in the diving and floating modes, the double-propeller propelling mechanism works in the advancing and retreating modes and the turning mode, the posture adjusting mechanism works in the gravity center adjusting mode, and the temperature difference power generation device works in the temperature difference power generation mode. The robot further has an underwater automatic obstacle avoidance function, detection modules with different functions can be carried according to actual task requirements, and specific tasks such as underwater observation, exploration and aerial photography can be completed in a complex environment.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, in particular to a small multifunctional underwater robot and its working method. Background technique [0002] The ocean area accounts for 70.8% of the total area of ​​the earth, and it contains extremely rich natural resources. With the gradual reduction of land resources, the dependence of the world economy on the ocean and the possibility of utilizing ocean resources are also increasing. The underwater robot has become one of the effective tools for human beings to explore and develop the ocean and expand the blue economic space. It is playing an increasingly important role in hydrological monitoring, aquaculture, underwater reconnaissance, and seabed exploration. However, how to use underwater robots to effectively develop and utilize marine energy, water resources, and monitor hydrological data is still an important problem facing society. [0003] Existing underwater robots can ...

AI Technical Summary

Problems solved by technology

[0003] Existing underwater robots can generally be divided into four categories, namely, manned underwater robots, cabled underwater vehicles (ROVs), untethered autonomous underwater vehicles (AUVs) and underwater gliders. It is a large-scale underwater robot, a medium-sized underwater robot, a small underwater robot and an ultra-small underwater robot. Due to the characteristics of high cost, high maintenance cost, large space occupation, complicated operation and large power consumption of large and medium-sized underwater robots, make its application subject to certain restrictions
