The easy read is here at Discover.
. . .
Their neural circuitry was programmed with just 30 “genes,” elements of software code that determined how much they sensed light and how they responded when they did. The robots were initially programmed both to light up randomly and to move randomly when they sensed light.
To create the next generation of robots, Floreano recombined the genes of those that proved fittest—those that had managed to get the biggest charge out of the food source.
. . .
By the 50th generation, the robots had learned to communicate—lighting up, in three out of four colonies, to alert the others when they'd found food or poison. The fourth colony sometimes evolved “cheater” robots instead, which would light up to tell the others that the poison was food, while they themselves rolled over to the food source and chowed down without emitting so much as a blink.
Some robots, though, were veritable heroes. They signaled danger and died to save other robots. “Sometimes,” Floreano says, “you see that in nature—an animal that emits a cry when it sees a predator; it gets eaten, and the others get away—but I never expected to see this in robots.” |
The Abstract of the scholarly paper is at Science Direct, with links allowing one to buy the whole paper. | We conducted repeated trials of experimental evolution with robots that could produce visual signals to provide information on food location. We found that communication readily evolves when colonies consist of genetically similar individuals and when selection acts at the colony level. We identified several distinct communication systems that differed in their efficiency. Once a given system of communication was well established, it constrained the evolution of more efficient communication systems. Under individual selection, the ability to produce visual signals resulted in the evolution of deceptive communication strategies in colonies of unrelated robots and a concomitant decrease in colony performance. This study generates predictions about the evolutionary conditions conducive to the emergence of communication and provides guidelines for designing artificial evolutionary systems displaying spontaneous communication. |

| So it's not that humanity is a flawed creature, it's just that intelligence coupled with competition leads to treachery. Hmmmm.... some would say this is original sin in humans. After a long chain of silly reasoning, one might conclude that robots have souls. And if that's so, then what can be said about the humans who created them? |

| I'd love a copy, Bng- It sounds like a very interesting read! |

Hmmm.... I did no know that.
On a related thought, in the interests of the 60 Second Rule, maybe we can't help but create AI in our own image.... scary that. |

I saw something sort of in this field a few years back, it's goal was just to build a robot which can move the best with the limited number of parts available. The comp did all the design work, but did quite well via trial and error, making some very strange and unexpected designs, the best being a snake like thing which rolled itself sideways.
On a related note did anyone catch the Terminator show last week? The insights into the intelligent chess puter were really cool. |

Also heres an article from last year about a bot which can build copies of itself. |
