Item Human-robot collaboration in industrial applications: Safety, interaction and trust(2017-07) Maurtua, Iñaki; Ibarguren, Aitor; Kildal, Johan; Susperregi, Loreto; Sierra, Basilio; ROBOTICA_AUTOMAHuman-robot collaboration is a key factor for the development of factories of the future, a space in which humans and robots can work and carry out tasks together. Safety is one of the most critical aspects in this collaborative human-robot paradigm. This article describes the experiments done and results achieved by the authors in the context of the Four-ByThree project, aiming to measure the trust of workers on fenceless human-robot collaboration in industrial robotic applications as well as to gauge the acceptance of different interaction mechanisms between robots and human beings.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.
