And it works just like it does in the animal.

The dog followed its master, wagging its tail.

You want the money spent on products advertising so the income is greater. So you invest in it.

But of course, this is a passive tail.

Albert hands me the knife.

That's her.

Osidius is right there.

So you cut off her tail?

Even from the tail.

Watch this.

We just got a lead on the trinity killer.

So for TED we actually built a robot, over there, a prototype, with the tail.

That's pretty flashy for some festival show. Here they go again... What a bunch of troublemakers they are!

But on the other side of that predatory gaze is a female husky in a play bow, wagging her tail.

Correct. But they're not...

Twisted tail,

Lizardslaw anyone?

Alys, don't forget your rat tail

But geckos do it better.

And I said, Well, what exactly is the process?

And it was unstable without its tail. Now mostly tails limit maneuverability,

You have to figure out exactly what genes matter.

You're going to throw it out, you throw it out, and you hold it.

I've already got a tail on him.

The tail I could live with.

And when it goes, we're always happy.

So watch this kangaroo.

Suck my ectoplasmic Schwanzstücke!

He turned his tail and ran.

And watch it now slip, and see what it does with its tail.

And it's better than that, it just in the slide maneuvers in mid air.

I've got something on you.

Marc Raibert built a Uniroo hopping robot.

The dog bit the cat on the tail.

Maybe I can touch the bottom.

Flush it down the pipe, see if it comes out on my end.

We said, Well, what do tails do?

Even though we put a passive bar there.

My dog is wagging his tail.

In fact, I could even add some movement to my sculptures.
