iCat: Human-robot interaction platform

When you are interested in a platform for human-robot interaction research, maybe the "iCat" is interesting for you (
http://users.pandora.be/vanbreemen/work.html ).
The iCat is a mechanically rendered robot head that can show many facial expressions. It also has a wide variety of sensors. It connects to a PC using USB. A dedicated SDK has been developed to program (animate) this robot.

Interesting. How many servos did you use to control the facial expressions? (I count four, based on the pictures - two for the mouth and one for each set of eyebrows and eyelids). The site says you used 13 servos total. The head looks like it pans and tilts, so that's two, and you will need locomotion, so that is two more, but so far my total is only 10 servos. How are the other 3 used? Even if each eyebrow and eyelid has a dedicated servo instead of sharing one btween the set, I still have one servo left over.

hi Bill,
eye-brows : 2 servo's eye-lids : 2 servo's eyes : 3 servo's (up/down movements of the eyes are linked, each eye can independently move left/right) lips : 4 servo's head : 1 servo (up/down) body : 1 servo (left/right)
Greetings,
Albert

Not what I expected. Why did you want the eyes to be able to move side-to-side independently? I'm also surprised that the lips needed 4 servos instead of two..
What's the price for these units?
