A fair amount of good recent robotics papers are also published in German. My daughter was at an internship and found a good robotics paper in German relevant to her project and actually found it reasonably easy going with high-school AP-German level of language skill. Of course a robotics paper is half math anyway, and German isn't shy about borrowing technical terms from other languages.
