Researchers use tough sea slug muscles to build a biohybrid robot
We're a long way from building the half-human, half-machine cyborgs of science fiction, but we are taking small (very slow) steps in that direction. Case in point is this biohybrid robot from Case Western Reserve University. It 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.
