We aim to set up a strong research network built around the three collaborators towards a very ambitious and very interdisciplinary project that will be financed by the Horizon Europe program. The project involves approaches from economics, management, administrative sciences, psychology, computer science and mechanical engineering. We will explore how citizens can and should be involved in the design and implementation of smart systems for public services (co-engineering) and policy making (co-governance). We will theoretically and empirically assess some viable methods of aggregating public opinions on the ethical and moral aspects of automated systems and robots in public services. We propose a new methodology for integrating citizens' contribution into the design and governance of smart public services, which will improve on existing approaches that are too technocratic and hypothetical. We will identify the dimensions that explain which utilities could benefit from automation using intelligent systems. These dimensions will allow us to measure whether the citizen approach that we propose is really useful and leads to better designed public services and policies.
