Embodiment 1

[0041] Example 1: Reference Figure 1-10 .

[0042] Specific reference Figure 1-5 , A snake-shaped amphibious robot with modular joints, comprising a plurality of universal modules 1 connected end to end in series, and the first universal module 1 and the last universal module 1 of the snake-like amphibious robot are respectively A head protective shell 3 and a tail protective shell 4 are provided. In this embodiment, the head protective shell 3 is cylindrical, and the tail protective shell 4 is conical. In the actual implementation of the present invention, the implementer can Choose the appropriate shape of the first protective shell 3 and the rear protective shell 4 according to the implementation conditions. A retractable waterproof corrugated sheath 2 is provided between the two adjacent universal 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, the waterproof corrugated sheath...

Embodiment 2

[0071] Example 2: Reference Figure 11-13 .

[0072] This embodiment is basically the same as Embodiment 1, and the difference lies in:

[0073] In this embodiment, the telescopic driving mechanism 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.

[0074] Preferably, the central position of the two connecting seats 52 is provided with a threaded hole for matching with the positive and negative threaded connecting rod 58, and the intersection of the positive and negative threads of the positive and negative threaded connecting rod 58 is located at the center of the two connecting seats 52 At the midpoint of the line.

[0075] In this embodiment, the driving motor is a threaded motor. When the driving motor 57 rotates in the forward direction, it drives the positive and negative threaded connecting rod 58 connected to it to rotate, and the rotation direction is the same as that of the driving ...

Abstract

The invention discloses a snake-like amphibious robot provided with modular joints. The robot comprises multiple universal modules which are connected in series end to end, one of two adjacent universal modules which are movably connected can have pitching motion or/and yawing motion relative to the other universal module, and the first universal module and the last universal module of the snake-like amphibious robot are provided with a cylindrical head protective case and a cone-like tail protective case respectively. The snake-like amphibious robot provided with the modular joints has the advantages of flexible action, simple structure, low cost, reliable and stable performance and the like which existing products do not have.

Description

Technical field [0001] The invention relates to the field of robots, in particular to a snake-shaped amphibious robot with modular joints. Background technique [0002] In today's society, with the rapid development of robotics technology, robots can already replace humans in many high-risk situations, and can also replace humans in exploring unknown worlds on some occasions. Snake-shaped amphibious robots are a typical representative of this type of robot. Not only can they move flexibly in the water like traditional underwater robots, but they can also switch between underwater and land environments flexibly, and can adapt well to various complex environments. [0003] The snake-shaped amphibious robot has the characteristics of good stability, small cross-section, and flexibility. It can walk on various rough, steep, rugged and complex terrains, climb obstacles, and swim in the water. It is based on wheels or legs. It is difficult for a robot as a walking tool to do it. Most o...
