There have been a number of soft robots inspired by the ancient art of paper folding – origami – recently, including polymer-based microgrippers and the safety-first Twister. Researchers from Harvard and MIT say that robots made of soft materials are often not as strong as their rigid counterparts. This thinking has led to the development of inexpensive artificial muscles that have been designed to give soft robots superpowers.
