Is the robot in that logo...... leaning against the text....... holding it's knees......... and sighing?

I'm replying quite late, but yes, he's doing exactly that. Also, the girl in the picture is the robot's user interface. That is, a part of the robot.

Quite late is an understatement. My 5 year old comment was rhetorical in case you didn't realize. The whimsy/sarcasm doesn't come through in text now that I read it again 5 years later. I just thought it was one of those oddly funny things you only can find in the world of anime.
