Edible origami robots.

Edible origami robots. Well, swallowable, and it won't get digested as it goes through your system. "A tiny origami robot that can unfold itself from a swallowed capsule and, steered by external magnetic fields, crawl across the stomach wall to remove a swallowed button battery or patch a wound."
"Stick-slip only works when, one, the robot is small enough and, two, the robot is stiff enough. With the original Mylar design, it was much stiffer than the new design, which is based on a biocompatible material." "Because the stomach is filled with fluids, the robot doesn't rely entirely on stick-slip motion." "In our calculation, 20 percent of forward motion is by propelling water -- thrust -- and 80 percent is by stick-slip motion."
"In the center of one of the forward accordion folds is a permanent magnet that responds to changing magnetic fields outside the body, which control the robot's motion. The forces applied to the robot are principally rotational."
