This Robot Is Part Sea Slug

We usually think of cyborgs as part human, part machine, but roboticists don't limit themselves that way. Researchers have developed a hybrid robot built with body parts from a novel source: sea slugs.

The new robot combines a Y-shaped muscle from the mouth of a California sea hare (Aplysia californica) with a 3D-printed skeleton.

Researchers surgically removed the so-called "I2" muscle from the mouths of sea slugs and glued them to flexible, 3D-printed plastic frames. When the muscles were subjected to an external electric field, the resulting contractions produced a deliberate clawing motion that was able to move the tiny robot up to 0.2 inches (0.5 centimeters) per minute.
