Putting surgery one step closer into the realm of self-driving cars and intelligent machines, researchers show for the first time that a supervised autonomous robot can successfully perform soft tissue surgery. The robot outperformed expert surgeons and current robot-assisted surgical techniques in open bowel surgery in pigs. By taking human intervention out of the equation, autonomous robots could potentially reduce complications and improve the safety and efficacy of soft tissue surgeries, about 45 million of which are performed in the U.S. each year.

Robot-assisted surgery currently relies on the surgeon to manually control it, and o...

Biochemical sensing b/n organisms could have far reaching implications in ecology, biology, and robotics. 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 Ruder, an assistant professor of biological systems engineering in both the College of Agriculture and Life sciences and the College of Engineering.

“We found that robots may indeed be able to have a working 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...
