'Living' robots powered by muscle

Professor Carlo Montemagno, of UCLA, has made itty bitty robots using metal or plastic "skeletons" and actual living muscle to move them around.

They're absolutely alive," Professor Montemagno told BBC News. "I mean the cells actually grow, multiply and assemble - they form the structure themselves. So the device is alive."

The devices (critters?) are microscopic now. When they grow up, of course, they look like Arnold Schwarzenegger.

It doesn't say how they're powered. But, if they combine it with this technology, they can have a living, self-sustaining robot/organism/thingy. Now all they need is a way for it to reproduce itself to be a fully qualified new species.
