Temperature-driven 4D printing robot

Abstract

The invention belongs to the field of robots, and discloses a temperature-driven 4D printing robot. The robot comprises a robot body and driving feet arranged at the periphery of the robot body, wherein the center of each driving foot is provided with a liquid medium pipeline in a penetrating mode; liquid media are filled in the pipelines, and the robot body is internally provided with a temperature control unit; the temperature control unit is used for regulating the temperature of the liquid media in the pipelines in real time; the driving feet are made from shape memory alloy materials; when the temperature of the liquid media is changed, the driving feet are deformed according to the temperature change, so that the form of the driving feet is changed; and thus, the robot body is moved.Through the 4D printing robot, under the condition of no external forces utilized, the leftward or rightward walking of the robot can be achieved according to the requirements; and the 4D printing robot has the characteristics of the simple structure, higher efficiency of a crawling mechanism, applicability to intelligent control and multi-degree-of-freedom walking and the like.

Description

technical field [0001] The invention belongs to the field of robots, and more specifically relates to a temperature-driven 4D printing robot. Background technique [0002] With the continuous advancement of science and technology, human beings are gradually moving towards artificial intelligence in life and production. In recent years, thanks to the rapid development of computers, robot technology has developed rapidly. An integral part of our life and production activities has also become more efficient due to the assistance of robots. The small crawling soft machine is an operating machine that can automatically walk along the inside of the pipeline or in narrow terrain. This machine can replace humans to detect narrow terrain, and can diagnose and detect in various complex pipeline environments. Therefore, it is widely used in pipeline damage detection, geological investigation, life exploration after earthquake, etc. At present, traditional small crawling machines are ...

AI Technical Summary

Problems solved by technology

At present, traditional small crawling machines are mainly composed of rigid bodies and joints. They can quickly complete crawling actions. However, they also have some disadvantages.

[0003] In addition, most of the currently existing crawling soft machines driven by shape memory alloy wires use wiring to heat the shape memory alloy wires. This method of energization heating has the following disadvantages. , after the power supply is exhausted, it is more troublesome to replace the power supply

Secondly, directly let the shape memory alloy wire exchange heat with the air. Since the thermal conductivity of the air is relatively low, the shape memory alloy wire cannot achieve rapid heat dissipation, which makes the crawling mechanism less efficient.
