They call their experiment an "origami robot" because the accordion-shaped gadget gets folded up and frozen into an ice capsule. "You swallow the robot, and when it gets to your stomach the ice melts and the robot unfolds," said Daniela Rus, a professor who directs MIT's Computer Science and Artificial Intelligence Laboratory. Researchers at the Massachusetts Institute of Technology are designing an ingestible robot that could bpatch wounds, deliver medicine or dislodge a foreign object. "They tried rice paper and sugar paper and hydrogel paper, all sorts of different materials," Rus said. In the meantime, the researchers have created an artificial stomach made of silicone to test it.
