Some living organisms feature an unusual muscle structure, which allows them to control the stiffness of their body, or various parts of it. Examples include elephants' trunks, our tongues, and octopus tentacles. Researchers working on the Octopus Project have so far successfully designed a robotic tentacle, with the ultimate aim of creating a full-bodied robotic octopus.
