AI Technical Summary

Benefits of technology

[0037]As set forth above, according to the present invention, a deep-sea exploration multi-joint underwater robot system probes the sea floor with the minimum area to support to minimize the disturbance of the deposited soil of deep seafloor, and is capable of standing still with deep-sea legs and changing posture of the system, thus stable and high-precision underwater operations can be achieved.

[0038]In addition, the deep-sea exploration multi-joint underwater robot system of the present invention is capable of performing stable and high-precision operations even at the complex seafloor topography such as slopes, rugged terrain, etc. In addition, the capability of the system to travel by walking about the seafloor allows an extra close and continuous expl

Problems solved by technology

However, in a close on-the-spot survey of the deep sea, which consists of sediments, the propeller often has an issue of vortex flow to disturb the seabed, and a landing on the ocean floor for a close investigation requires a certain period of time until the mud subsides from tumult by the propeller flow, which renders the exploration difficult when an urgent observation is needed for a moving life and the like.

Second, their applications are marine scientific research, and the exploration and development of marine resources.

First, screw propulsion is effective in the cruising types of AUVs, but it hardly achieves the stability of control in the ROVs that require operating precision.

Second, track propulsion systems are difficult to run about an irregular seabed terrain and an area with obstacles and they have an inherent disadvantage from their running behavior that interferes with the seabed.

The seabed has ever-present constraints of a variety of obstracles such as sunken ships, fisheries, ropes and abandoned fishing nets, and constraints of seabed topography such as reef, soft ground and the like, which obstructs the track propulsion systems from runn
