“In this July 13, 2016 photo, a tiny “origami robot” floats, at right, towards a “wound” in a stomach model at the Massachusetts Institute of Technology in Cambridge, Mass. Steven Guitron, a mechanical engineering masters student, and others at MIT have developed these tiny ingestible robots which are “folded up” – hence the name – and swallowed in order to complete certain tasks within the body. So far they can be used to patch wounds, remove foreign objects, and even deliver medicine within the body. The robots unfold when ingested, and can be controlled by magnet forces outside of the body. (Elise Amendola/Associated Press)
