Virginia Tech scientist develops model for robots with bacterial brains

BLACKSBURG, Va., July 16, 2015 – Forget the Vulcan mind-meld of the Star Trek generation — as far as mind control techniques go, bacteria is the next frontier.

In a paper published today in Scientific Reports, which is part of the Nature Publishing Group, a Virginia Tech scientist used a mathematical model to demonstrate that bacteria can control the behavior of an inanimate device like a robot.

“Basically we were trying to find out from the mathematical model if we could build a living microbiome on a nonliving host and control the host through the microbiome,” said Warren Ruder, BSE assistant professor.

"We found that robots may indeed be able to function with a bacterial brain,” he said.

For future experiments, Ruder is building real-world robots that will have the ability to read bacterial gene expression levels in E. coli using miniature fluorescent microscopes. The robots will respond to bacteria he will engineer in his lab.

On a broad scale, understanding the biochemical sensing between organisms could have far reaching implications in ecology, biology, and robotics.
