Embodiment 1

[0050] Embodiment 1: refer to Figure 1-10 .

[0051] Specific reference Figure 1-5 , a snake-shaped amphibious robot with modular joints, comprising a plurality of general-purpose modules 1 connected end to end in series, the first general-purpose module 1 and the last general-purpose module 1 of the snake-shaped amphibious robot are respectively A head protection shell 3 and a tail protection shell 4 are provided. In this embodiment, the head protection shell 3 is cylindrical, and the tail protection shell 4 is conical-like. In the actual implementation of the present invention, the implementer can According to the implementation conditions, the shape of the appropriate head protection shell 3 and the tail protection shell 4 is selected. A retractable waterproof corrugated sheath 2 is arranged between the two adjacent general modules 1, and the two ends of the waterproof corrugated sheath 2 are connected. At the corresponding ends of the two adjacent universal modules 1, ...

Embodiment 2

[0080] Embodiment 2: refer to Figure 11-13 .

[0081] This embodiment is basically the same as Embodiment 1, the difference is:

[0082] In this embodiment, the telescopic driving device is a driving motor 57 , and the telescopic connecting rod is a positive and negative threaded connecting rod 58 driven by the driving motor 57 .

[0083] Preferably, the central positions of the two connecting seats 52 are provided with threaded holes for matching the positive and negative threaded connecting rods 58 , and the intersection of the positive and negative threads of the positive and negative threaded connecting rods 58 is located at the center of the two connecting seats 52 at the midpoint of the line.

[0084] In this embodiment, the driving motor is a threaded motor. When the driving motor 57 rotates in the forward direction, it drives the forward and reverse threaded connecting rod 58 connected to it to rotate, and the rotation direction is the same as that of the driving mo...

Abstract

The invention discloses a buoyancy adjusting device for a snake-shaped amphibious robot and the snake-shaped amphibious robot. The buoyancy adjusting device comprises two joint shells and connecting seats arranged on the two joint shells. A waterproof elastic skin is arranged between the two joint shells. Shear type mechanism fixing pieces are arranged on the two connecting seats. Shear type mechanisms are arranged between the two shear type mechanism fixing pieces. One of the two connecting seats is provided with a telescopic drive device. A telescopic connecting rod which can drive the shear type mechanisms to extend and contract and is driven by the telescopic drive device is arranged between the two connecting seats. The snake-shaped amphibious robot further comprises multiple universal modules. The universal modules are connected with one another end to end in series. One of every two adjacent universal modules connected in series can complete the pitching motion and the yawing motion. The buoyancy adjusting device for the snake-shaped amphibious robot and the snake-shaped amphibious robot have the beneficial effects that buoyancy adjustment is convenient, energy is saved and the actions are flexible.

Description

technical field [0001] The invention relates to the field of robots, in particular to a buoyancy regulating device for a snake-shaped amphibious robot and the amphibious robot. Background technique [0002] In today's society, with the rapid development of robot technology, robots can already replace humans to work in many high-risk situations, and can also replace humans to explore the unknown world on some occasions. Snake-shaped underwater robot is a typical representative of this type of robot. It can not only move flexibly in water like traditional underwater robots, but also flexibly switch between underwater environment and land environment, and can adapt to various complex environments. . [0003] Snake-shaped robots have the characteristics of good stability, small cross-section, and flexibility. They can walk on various rough, steep, and rugged terrains, and can climb obstacles and swim in water. This is done with wheels or legs. Robots with walking tools are dif...
