This Meat Transformer Wants To Retrieve The Weird Things You've Swallowed

This origami robot is designed to be swallowed in an ice capsule (left) before unfolding inside the stomach. Scientists have created a tiny, ingestible robot made from pig intestine that might be able to retrieve swallowed objects without surgery. The robot is built from a magnet attached to folds of dried meat typically used in sausage casings. It needs no tether or power source, instead being guided by magnets outside the body. Though swallowed in an ice capsule, the robot unfolds inside the stomach as its casing melts.
