120,000 pictures are taken care of by Ryszadr Moroz, paper restorer at the Westphalian State Museum for Art and Cultural History, which he brings into shape on a daily basis for exhibitions at the museum. So far the severely dirtied and often fragile pictures were processed manually. Thereby about two and a half hours had to be scheduled for cleaning a surface of 800 x 600 mm. Moroz wanted to save a lot of time by using a rubber eraser.
The restorer's query aroused the curiosity of three students of the mechanical engineering faculty in the Hans-Böckler-Schule at the Berufskolleg in the city of Münster. Jan Hallek, Guido Madsack and Jürgen Reinker decided to make this project the topic of their degree thesis. Thus they developed the first eraser robot in the world to process pictures fully automatically.
