The Bibliotheque du Film, attached to the world famous Cinématheque in Paris has a very interesting site about the "Maschinenmensch" robot woman from Metropolis.
Videos of the restored version and rare images donated personally by Fritz Lang as well as detailed 3D photos of the robot replica made by Walther Shultze-Mittendorf can be found here :
