A variable-stiffness tendril-like soft robot based on reversible osmotic actuation

A variable-stiffness tendril-like soft robot based on reversible osmotic actuation. Indrek Must et al (2019), Nature Communications Soft robots hold promise for well-matched interactions with delicate objects, humans and unstructured environments owing to their intrinsic material compliance. Movement and stiffness modulation, which is challenging yet needed for an effective demonstration, can be devised by drawing inspiration from plants. Plants use a coordinated
