Story highlights The Open Worm Project aims to recreate the behavior of the common roundworm in a machine The open source project has taken four years to model 302 of the worm's neurons in its software It had its first major breakthrough recently when the software independently controlled a Legobot The robot mimicked some of the behaviors of the worm, responding to external stimulus through sensors

Called the Open Worm Project, the research brings together scientists and programmers from around the world with the aim of recreating the behavior of the common roundworm (Caenorhabditis elegans) in a machine.

The open source project recently had its first major breakthrough when its software -- modeled on the neurons of the worm's nervous system -- independently controlled a Lego robot.

The machine's sensors, without any prior programming, made the robot behave in a similar fashion to C. elegans, approaching and backing away from obstacles or stimulated by food.

While the developers say it will be some time before the Lego bot will be avoiding predators or searching for a mate, scientists say the project shows that artificial intelligence, or AI as it is known, is coming out of the realm of science fiction.

"We've been working on it for four years and while we have a lot more to achieve it's been the most surprising project I've been involved in," project coordinator Stephen Larson told CNN. "It's certainly exceeded my expectations."

With the worm's nose neurons replaced by a sonar sensor and the motor neurons running down both sides of the worm replicated on the left and right motors of the Lego bot, the robot could emulate the worm's biological wiring.

Larson said that while the open source project is still awaiting peer review, and the scientists and researchers in the experiment are reluctant to make any bold claims about how closely it resembled biological behavior, the result were nevertheless impressive.

"We definitely have further to go, but I think what captures people's imagination is how much information we have managed to put together," Larson said.

"We know we have the correct number of neurons, we have them connected together in roughly the same way that the animal has, and they're organized in the same way in that there are some neurons that give out information and other neurons that receive information."
