Example Embodiment

[0010] figure 1 Among them, a snake-shaped robot is composed of a snake head 1, a snake tail 2, a number of node ends 3, 4, 5, 6, a common wire spring 7, a shape memory alloy (SMA) spring 8, 9, 10, 11 and a foot 12. Component composition. The joint end 3 and the joint end 4 are connected by a common wire spring 7 fixed on the joint ends 3 and 4 and four shape memory alloy (SMA) springs 8, 9, 10, 11, and the other sections can be deduced by analogy, namely Can form a snake-shaped robot. The joint ends are made of insulating materials, and each joint end is equipped with a mechanism that can control the extension and retraction of the foot 12 (see figure 2 ). This control mechanism is composed of shape memory alloy (SMA) spring 13, connecting rod 14, 15, 16, spring leaf 17 and slide 18 installed at the end of the joint. Foot 12, according to the characteristics of the crawling ground, can be equipped with rubber pads or metal Sharp teeth. Its working principle is: when the shape ...

Abstract

A snake-shaped robot for finding failure in long pipeline and searching people or object in accident is composed of snake head, snake tail and several segments which has the drive unit consisting of ordinary steel wire spring and shape memorizing alloy (SMA) spring, telescopic legs, and heating or cooling unit.

Description

technical field [0001] The invention relates to a robot, in particular to a snake-like robot with telescopic movement using a shape memory alloy (SMA) spring and a common steel wire spring as a driving device. Background technique [0002] Japan's TOHOLU University uses micro-manufacturing technology to drive shape-memory alloys. It is a miniature snake-like robot that is suitable for the human intestinal tract or blood vessel environment. However, the human body environment severely restricts the heat transfer and heat dissipation of shape-memory alloys, which limits the application area. Another kind of miniature multi-joint electromagnetic peristaltic robot is composed of several drive units, elastic sealing film, rear cabin, and front cabin. The drive units of each section are connected by universal joints. It realizes the robot system by means of the friction force of the interface. The overall driving movement can only move forward and backward, and cannot climb trees ...
