Robots designed by genetic algorithms

Germany's Fraunhofer-Institut is making "genetic robots" by using genetic algorithms to design optimal forms: "The optimal form is decided based on a physics engine that takes into account the tasks and terrain and then designs the robot accordingly. The robots are made of ball and socket joints and connecting tubes and can change shape depending on the required tasks. The resulting robot is then 3D printed."
