The European Training Network on PErsonalized Robotics as SErvice Oriented applications – PERSEO – aims at training and creating a new generation of interdisciplinary researchers and professionals with an entrepreneurship ethos and transferrable skillset to face both societal and technological research challenges of this forthcoming market of personal robots. These consist respectively in the development of personalized and acceptable robot’s perceptual and interaction capabilities to be distributed as Cloud Services personal robot applications as companions, in rehabilitation, and for edutainment. The PERSEO research and training program is organized into three Research Themes aimed at investigating personalization of robot capabilities at different levels of possible Human-Robot Interaction (HRI), namely “Physical, “Cognitive”, and “Social”. This requires a set of research skills ranging from computer science and AI to automation, ethics, and psychology, and the use of a collaborative design approach. Integration Milestones, will provide co-working societal problems where collaborative design/implementation is fostered and supported by partner organizations.
