"Gurus at the Laboratory of Intelligent Systems in the Ecole Polytechnique Fédérale of Lausanne have been working on "evolving robots" for quite some time, but the latest breakthrough is easily the most astounding (and in turn, terrifying) of all. According to new research that was just made public, a gaggle of robots programmed to use Darwinian selection in order to learn, evolve and mutate have now successfully moved sans collisions through a maze and helped each other push tokens around in order to achieve a common goal.
