Itsy Bitsy, Teeny Weeny, Tiny Rat Heart Controlled Robot?

When I was a kid, I couldn't get enough of the cartoon The Jetson's. I was fascinated with all of the gadgets, especially the robots. Rosie was exactly what I needed. A robot that would clean my room! That would have been awesome. Today, we have all kinds of different robots, but I find one in particular the most fascinating. This fascinating robot is powered by a heart muscle that came from a rat.

This robot was designed by scientists in Korea, and it is smaller than the thickness of a fingernail. This "itsy bitsy" robot moves like a crab at the lightning speed of .0002 miles per hour. Scientists hope that this new technology will lead to bigger and better things. They hope that one day, that it will be used to carry agents to bust up clots in clogged blood vessels. Although this microscopic "Rosie" is highly advanced, it still has a long way to go. The human blood stream flows around two miles per hour, and it must be able to travel faster than that in order to compete with the blood flow. Hey, I've got an idea. How about they use a heart muscle from a Cheetah instead? Wouldn't it be faster then? Well, it probably wouldn't, but maybe they will try.

All in all, yesterday's cartoon has become today's reality, and robots have become much more advanced than I could have ever imagined. I only have one issue concerning today's technologies. Where is the robot that is going to clean my room?
