New Scientist recently featured a video which showcases robotic machines capable of learning, reproducing, and evolving on their own. The machines interact with their surroundings and learn to solve any problems they encounter. Then the most successful machines are programmed to "mate" and pass on their virtual DNA. The progeny of these robots are manufactured by 3D printer and assembled autonomously. Researchers think such systems could one day allow robotic machines to learn and evolve on their own in order to complete complex tasks, such as cleaning a nuclear site or exploring an asteroid.
