Meet your new robotic parasite

One of those things that says, "Please stop reading now" :

Doctors currently explore the gut using endoscopes, which have to be fed through the body, or "camera pills" that must be swallowed by a patient.
A pill capable of wriggling through the gut on its own could be a valuable tool, says Andrew Gardner, an independent medical imaging expert at University College London.

Yes, you have to go over to New Scientist to see the picture. It's two tail spines short of a centipede. And it's crawling through pig guts right now. Eeeeww!

"If something this complicated goes wrong, it could be very hard to get out."

Eeeeww!
