At most universities the education of engineering and design students is strictly separated from each other. However, starting professional careers most students get involved into interdisciplinary projects. In particular the rising complexity of modern high-tech consumer products demands interdisciplinary approaches. Nevertheless, most engineers and designers have their first encounters with each other on the job. To resolve this deficiency young engineering and design students at the University of Duisburg-Essen get the opportunity to participate in joint projects of the Chair of Mechatronics and the faculty of industrial design. This paper describes the cooperation of engineering and design students exemplifying design and redesign of a large scale walking machine.
