So, I remember seeing this video a long time ago. It is basically that they had made a robot in Japan that could dance (pretty close) to human motions. So, in this video they played some salsa song and programmed the robot to dance to it (however, some parts don't really look like salsa... but come on - its a freakin' robot, what can we expect). It does show you how advanced the robotics engineers are in Japan. I like the details of when he shakes his butt, his eyes change color. That was funny.
