Abstract

A special suspension-type tracked underwater robot adaptable to ultra-soft geological conditions comprises traveling mechanisms, wherein the traveling mechanisms are track-mud sled structures, the mud sled structures are fixedly arranged on two sides of each track, and the bottoms of the mud sled structures are higher than the bottoms of the tracks and are provided with arched plate heads; the arched plate heads are provided with plate water-jet devices capable of spraying water forwards; and in the traveling process of the traveling mechanisms, and the arched plate heads press water downwards to form a water film at the bottoms of the mud sled structures together with the water sprayed by the plate water-jet devices, so that the traveling mud resistance is reduced, and the robot can stably advance under ultra-soft geological conditions. The special suspension-type tracked underwater robot further comprises a propelling mechanism, an adjustment device, an operating module, and the like, can autonomously advance on a seabed, can suspend in water, can repair itself when broken, and can achieve detailed operations.
