A review of locomotion of snake robots

Abstract

In this review paper, we demonstrate the high structural flexibility and motion diversity of snake robots, which are important indicators to measure the performance of the mechanism. And animals in nature, especially reptiles, often have a high degree of flexibility and a variety of modes of movement in order to be able to shift through various terrains. Thus, making a robot with excellent performance, a bionic robot is a suitable choice. Currently, we have reviewed the state of the act in the snake-like machine. In the end, we conclude that with the simplicity of design and practice, it can be designed easily with unique constructures to complete modes of locomotion. Furthermore, we also provide the perspectives of future work.
