A ballerina gracefully dances on a small stage. She is followed not by a male partner, but by a robotic arm manipulator that seems to sense her every move. For NASA Goddard technologist Vladimir Lumelsky, the performance shows the future of robotics.

Okay, sorry, but when I looked at this video, it sure didn't look like an *arm*. In fact, I'd be willing to brand this as "not safe for work." ;)
