This paper presents two human-robot cooperative application scenarios of the project MeRoSy (Human-Robot Synergy) funded by the German Federal Ministry of Education and Research. The first scenario relates to the human-robot cooperation in an industrial application, while the second one refers to the robotic workplace assistance for people with disabilities. The presented scenarios reflect different aspects of human-robot interaction, among others different novel possibilities for human-robot interaction depending on different physical abilities of human co-worker. Beside the consideration of the human-robot cooperative technologies in two MeRoSy scenarios, this paper considers also the identification and classification of the ethical, legal and social implications (ELSI) in the context of human-robot cooperation.
