Sea-Slug Robot uses muscles taken from the mouth of a sea slug connected to 3D-printed components to move about, and — when an external electrical current is applied to force the muscles to contract — can 'walk' at the extremely unhurried pace of 0.43 centimeters a minute in a form of locomotion similar to a turtle crawling up a beach. The scientists who designed the bot say that in the future, groups of these creations could be used for lengthy missions which would tire traditional robots.

Using muscle cells instead of mechanical parts means that semi-organic bots can get energy from their natural environment — just like animals do.
