Modular Inflatable Kirigami Robot That Crawls Like Snakes

We have seen plenty of robots that are inspired by animals in nature, including snakes. This modular textile kirigami robot is capable of exhibiting movements like snake. It is driven by inflatable kirigami actuators, which as the researchers explain:

consist of a kirigami metamaterial with staggered linear cut patterns and an interconnected air pouch network embedded between two airtight textile layers. A distinctive feature of this class of actuators is that the cut pattern enables significant contraction through inflation-induced overlapping of sealed cut edges. 

Researchers connected multiple modules and used double air channels within each module to enhance the design.
