The first three conferences of this series successfully established a forum for research on cable robots worldwide. In total, close to 150 scientists from four continents gathered in Stuttgart, Duisburg and Quebec City to present the state of the art and latest research results. The next conference aims to present new results, to continue the forum for the exchange of ideas, and to establish contacts amongst all international teams. The next CableCon is integrated as session track into the IFToMM World Congress making latest research in cable-driven parallel robots visibile and open to all disciplines in mechanism and machine science.
