All-Robotic characters in Anime or Manga

[tecnowraith]

I have been wondering does anyone know any anime or manga with an all-robot cast/character, no humans? I know some movies are like this like the CGI film Robots and Bionicle movies.

ghost in the shell is close to that.

Ghost in the Shell, yes. There's also Appleseed (both manga were originally done by the same mangaka).

Nothing much else really comes to mind for me.
