About The Cover
ONLINE COVER From flat to functional. Origami is a popular inspiration for design of inexpensive, easily assembled robotic systems. Kim et al. took inspiration from Eurypharynx pelecanoides (commonly called the pelican eel), which has the ability to rapidly expand its mouth to capture prey. They designed soft robots made of silicone rubber that can unfold and stretch simultaneously. One origami robot could mimic the mouth movement of E. pelecanoides. Modifications in the fold designs and the stiffness of components allowed programmable designs and shapes, including crawlers and grippers that can be stored flat. [CREDIT: JAMIE SONG/SNU SRRC]
