Tiny Crab Robot Travels Through Blood Vessels

Scientists at Chonnam National University in Korea have have created a tiny robot that WALKS LIKE A CRAB THROUGH HUMAN ARTERIES hunting for blood clots. When it finds one, it releases drugs that unblock them. But wait! It gets freakier. The robot moves using heart muscles that have been grafted to the legs, and gets its power directly from sugar in the patient's blood stream. Someday, maybe we'll ALL have crabs from Korea.
