Computer Engineering, Electronics, Information Sciences and Mechanical Engineering are the essential disciplines in Mechatronics and Robotics leading to powerful, compact and ever smarter systems. Their evolution relies on progress in all these complementary scientific and technological fields. This workshop provides an international forum for the exchange of ideas, discussions on research results and the presentation of theoretical and practical applications in these domains. This conference is the expression of the shared ambition on the part of the Toulouse University (France) and the Liberec Technical University (Czech Republic) to publically present their common scientific research. The first edition was organized in 1993 (1993-Electro Workshop) in Liberec and its biennial form has led to the celebration of the 10th anniversary in 2011 (ECMS2011). The University of Mondragon (Spain) has joined the organization team in 2009. Due to the constant evolution, ECMS became an international event in 2011 (involving 10 countries). Since that time, the ECMS workshop has been co-sponsored by the Technical Council on VLSI (TCVLSI) of the IEEE Computer Society. The next ECMSM Workshop will take place in Toulouse from June 24th to June 26th 2013, in the south-western France. The organization relies on the cooperation of several University on the technological place of Toulouse such as the Paul Sabatier University (Université Paul Sabatier) and the National Polytechnic Institute of Toulouse (Institut National Polytechnique de Toulouse).
