swallowed a small battery? In the future Women's Nike Air Zoom Pegasus 35 Elemental Rose For Sale , a tiny robot made from pig gut could capture it and expel it.


Researchers at the Massachusetts Institute of Technology are designing an ingestible robot that could be used to patch wounds, deliver medicine or dislodge a foreign object. 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. "Then Men's Nike Hyperadapt 1.0 Tinker Blue Black For Sale , we can direct it to a very precise location."


It's still a long way before the device can be deployed in a human or animal. In the meantime, the researchers have created an artificial stomach made of silicone to test it.


Rus said one of the robot's most important missions could be to save the lives of children who swallow the disc-shaped button batteries that increasingly power electronic devices. If swallowed, the battery can quickly burn through the stomach lining and be fatal.


The robots could seek out and capture the battery before it causes too much damage, pushing it down through the gastrointestinal tract and out of the body.


The robot's flexible frame is biodegradable, made of the same dried pig intestine used for sausage casing. The researchers scoured markets in Boston's Chinatown before finding the right material to build an agile robot body that could dissolve once its mission was accomplished.


"They tried rice paper and sugar paper and hydrogel paper Men's Nike Hyperadapt 1.0 Habanaro Red Black For Sale , all sorts of different materials," Rus said. "We found that sausage casing has the best properties when it comes to folding and unfolding and controllability."


Embedded in its meaty body — it wouldn't be hard to make a kosher version, Rus said — is a neodymium magnet that looks like a tiny metal cube.


Magnetic forces control its movement. Researchers use remote-control joysticks to change the magnetic field, allowing the robot to slip and crawl through the stomach on the way to the object it is trying to retrieve or the wound where it must deliver drugs.


Would it hurt to ingest a robot? Probably not, said research team member Steven Guitron Men's Nike Hyperadapt 1.0 JP Team Orange Black For Sale , an MIT graduate student in mechanical engineering
