Robot Pill

You might heard of the pill camera, the tiny camera that can snap every inche of your digestion system, but this pill is different. Researchers at Carnegie Mellon develop this robotic pill which can spread its legs and crawl your intestine without damaging it.

It would be hard for a doctor to ask his patient to swallow something that can crawl their intestine.
