Here is the Geminoid F:

Geminoid F is the most realistic looking of the three. Her (or it's, if that makes you more comfortable)face and expressions were modeled after an actual, living person. However, feature-wise, she seems to be pretty limited. The only thing I've seen her actually do is read off pre-recorded messages, mimic the facial expressions and head motions of someone sitting in front of a camera, and bow.
The HRP-4C:

WARNING: The video for the HRP-4C has some pretty horrible background music going on while she sings. I apologize.
HRP-4C is the least realistic looking, but can do the most. For one thing, she can walk, although slowly and somewhat awkwardly. She also uses special software (much like Vocaloid software) so that her singing is NOT a recording of someone else, but is computer generated. She also mimics facial expressions and head motions as well, in the same way that Geminoid F does.
And finally, Actroid DER 2. (There is an Actroid DER 3 and Geminoid F is being sold by the company Kokoro as Actroid F, but excluding Actroid/Geminoid F, Actroid DER 2 is my favorite.)

DER 2 is considerably more realistic than HRP-4C, but not as much as Gemenoid F. She can stand, but she can't walk. What I find the most interesting about her is that she can answer questions!
DISCUSS:
-What do you think about humanoid robots?
-Will humanoid robots be more or less helpful in the future?
-Are there any robots you're particularly interested in?
-Pretty much anything robot related.
Now watch this be a thread no one ever comments in. DIE THREAD, DIE!!! XD
