Item Co-operative and distributed configuration(Springer Verlag, 2004) Altuna, Ander; Cabrerizo, Alvaro; Laresgoiti, Iñaki; Peña, Nieves; Sastre, Daniel; Weske, Mathias; Liggesmeyer, Peter; Tecnalia Research & Innovation; ADAPTACIÓN AL CAMBIO CLIMÁTICOConfiguration problem solving is a topic that drove a lot of interest within the AI community. The World Wide Web has appeared as the vehicle to share information and facilitate businesses like the provision of simple configuration capabilities to users. Ontologies have gained acceptance within the research community as the way to make applications interoperable and drive the next intelligent generation of the World Wide Web known as the Semantic Web that many consider as a future enabler of future advance forms of collaborative e-business. It is just this consideration what has motivated the OBELIX1 consortium to do research on multi-component product configuration, since collaborative design scenarios over the (Semantic) Web will become a future reality, but have not been researched in depth yet. This paper describes the efforts done and the results obtained in that direction.Item Natural multimodal communication for human-robot collaboration(2017-07) Maurtua, Iñaki; Fernández, Izaskun; Tellaeche, Alberto; Kildal, Johan; Susperregi, Loreto; Ibarguren, Aitor; Sierra, Basilio; ROBOTICA_AUTOMAThis article presents a semantic approach for multimodal interaction between humans and industrial robots to enhance the dependability and naturalness of the collaboration between them in real industrial settings. The fusion of several interaction mechanisms is particularly relevant in industrial applications in which adverse environmental conditions might affect the performance of vision-based interaction (e.g. poor or changing lighting) or voice-based interaction (e.g. environmental noise). Our approach relies on the recognition of speech and gestures for the processing of requests, dealing with information that can potentially be contradictory or complementary. For disambiguation, it uses semantic technologies that describe the robot characteristics and capabilities as well as the context of the scenario. Although the proposed approach is generic and applicable in different scenarios, this article explains in detail how it has been implemented in two real industrial cases in which a robot and a worker collaborate in assembly and deburring operations.
