Today's science videos: Nao

If you were looking for a personal robot, we've got one for you. They're about $15000, but there is a discount if you purchase in bulk.

We were originally intrigued by this first video, where each dancing Nao (pronounced "now") is responding to a central computer. This article explains how; it's something called quorum sensing, which is how many bacteria coordinate. (You learn something every day.)



After watching this, via Mental Floss, I got curious about these little suckers, and went to the Nao website. This is their promotional video:



Apparently it does not come with rocket launchers to get revenge on the dolt who knocked it over without so much as a "Pardonnez-moi." I would suggest such weaponry as a future enhancement.

There are other videos out there on various versions of Nao and the different things it can do. After watching them, all you'll need to do to get one for yourself is to dig up that spare $15000.
