Plants Inspire Design of Tiny Robots Powered by Moisture

(Engadget) Researchers have turned to plants for inspiration to create is a tiny, inchworm-like robot that runs on humidity. The researchers were inspired by plants like Pelargonium carnosum, the seeds of which can screw themselves into the ground, and pine cones that open and close depending on the humidity in order to ensure their seeds spread as far as possible. The seeds produce either a spinning motion that can drive seeds into the ground or an open and close motion that can keep seeds in place until conditions are optimal for dispersal.
The researchers have adapted this natural plant process to supply miniature robots with safe, constant power. Tiny robots have future use in fields ranging from medicine to the military.
