Abstract

The invention discloses a cephalopod simulating flexible contact wrist. The cephalopod simulating flexible contact wrist comprises a flexible colloidal part, a rigid skeleton, and a motor connecting frame, wherein the flexible colloidal part and the rigid skeleton are molded and connected into a whole body by casting and solidification; the rigid skeleton and the motor connecting frame are connected together through threaded fasteners; the flexible colloidal part comprises software silica gel, a tail end baffle plate, and a rigid nylon wire; the tail end baffle plate is connected to the tail end of the software silica gel through mold casting; the rigid skeleton comprises a U-shaped support, a reinforced copper pillar, and a buoyant foam board; the U-shaped support and the two ends of thereinforced copper pillar are connected through screw-thread fit; one through hole is formed in the buoyant foam board; and the motor connecting frame is used for connection with a double-shaft steering engine or a double-shaft motor so as to provide power. The cephalopod simulating flexible contact wrist is different from the flexible contact hand of a rigid mechanical structure, can provide goodpropulsive force in the process of swinging in water; and the under-actuated structure mode has relatively low power consumption, low noise and small environmental disturbance.

Description

technical field

[0001] The invention belongs to the technical field of underwater robots, and in particular relates to a flexible tentacles of bionic cephalopods. Background technique

[0002] With the development of science and technology, the development of new energy has become an important issue faced by all countries, and underwater robots are an important technical means to explore and utilize the ocean. Among them, bionic underwater robots can make up for the noise of other traditional underwater vehicles and promote Low efficiency and other shortcomings.

[0003] At present, most of the bionic underwater tentacles are rigid structures, with low flexibility and poor controllability. In the field of underwater bionic robots, bionic cephalopods have not yet completely solved the controllability of the tentacles. Contents of the invention

[0004] The purpose of the present invention is to provide a bionic cephalopod flexible tentacles, so as to solve the shortcomings...
