An underwater robot navigation and obstacle avoidance device

Abstract

The invention belongs to the field of robot obstacle avoidance, and specifically relates to an underwater robot navigation obstacle avoidance device, which includes a bottom plate, an air chamber is fixedly connected to the outer surface of the bottom plate, and an X-shaped rod is movably connected to the upper surface of the air chamber . The underwater robot navigation and obstacle avoidance device is equipped with a liquid inlet mechanism. When the equipment is in use, the external water flows to the inside of the liquid inlet mechanism under the action of the pressure difference, and the tapered stopper is pushed away. Trumpet-shaped, and the slope of the outer surface of the tapered stopper is equal to the slope of the inner surface of the pressurized pipe. While ensuring the sealing effect, the cross-sectional area of ​​the left end of the pressurized pipe is smaller than that of the right end. Due to the reduced cross-sectional area, the water pressure Increased, the high-pressure water column impacts the partition, the external impurities are discharged from the sewage pipe, and the clean water is discharged from the channel. The counterweight ball can control the floating and descending of the equipment through suction or discharge, which solves the problem of traditional underwater robots when they are moving. Low pressure, easy to block the problem inside.

Description

technical field [0001] The invention belongs to the field of robot obstacle avoidance, in particular to an underwater robot navigation obstacle avoidance device. Background technique [0002] The underwater robot, also known as the unmanned remote control submersible, is a kind of extreme operation robot that works underwater. The underwater environment is harsh and dangerous, and people's diving depth is limited, so underwater robots have become an important tool for developing the ocean. [0003] Due to the large differences in the hydrological conditions of different waters, affected by the external environment and the flow of water bodies, when the underwater robot operates in waters with low visibility and many impurities, it will be affected by external obstacles, the inside of the equipment will be blocked by impurities, and the outside of the equipment will be blocked. The power output is reduced, and the overall stability is reduced. In the absence of effective pow...
