Scientists Built Biological Robots Called ‘Spinobots’ Using A 3D-Printed Skeleton Powered By Spines Of Rats

Scientists Built Robots Using 3D-Printed Skeleton And The Spines Of Rats

Once again, for some strange reason, scientists are out there doing stuff to hasten the coming robot apocalypse.

Remember how I reported back in January about how scientists were in the process of moving us yet another step closer to a real-life Westworld by creating robots from living cells?

Yeah, well, the geniuses over at the University of Illinois at Urbana-Champaign just created some miniature biological robots they’re calling “spinobots” that are, and I quote, “powered by rat muscle and spinal cord tissue on a soft, 3D-printed hydrogel skeleton.”

“These are the beginnings of a direction toward interactive biological devices that could have applications for neurocomputing and for restorative medicine,” said study leader Martha Gillette, a professor of Cell and Developmental Biology.

That’s not the only thing this is the beginning of there, boss.

To make the spinobots, the researchers first printed the tiny skeleton: two posts for legs and a flexible “backbone,” only a few millimeters across. Then, they seeded it with muscle cells, which grew into muscle tissue. Finally, they integrated a segment of lumbar spinal cord from a rat.

“We specifically selected the lumbar spinal cord because previous work has demonstrated that it houses the circuits that control left-right alternation for lower limbs during walking,” said graduate student Collin Kaufman, the first author of the paper. “From an engineering perspective, neurons are necessary to drive ever more complex, coordinated muscle movements. The most challenging obstacle for innervation was that nobody had ever cultured an intact rodent spinal cord before.”

New Scientist reports…

The spine and muscle were connected to a flexible scaffold with two arms sticking out perpendicular to the spine, so that when the muscle contracted, the scaffold flexed and the arms pointed towards one another.

“The spinal cord is able to recognise these muscles and do what it does in the body – create these rhythmic contractions – after being out of the body for more than a week,” says Kaufman. The contractions could be controlled by adding or removing neurotransmitters from the system.

As for why these scientists are flirting with making robots more human-like than ever, Kaufman said, “The development of an in vitro peripheral nervous system – spinal cord, outgrowths and innervated muscle – could allow researchers to study neurodegenerative diseases such as ALS in real time with greater ease of access to all the impacted components. There are also a variety of ways that this technology could be used as a surgical training tool, from acting as a practice dummy made of real biological tissue to actually helping perform the surgery itself.”

Okay, fine. I guess those are good reasons.

Still… someone needs to keep an eye on these folks.
