Robotic services, which have started to appear in urban
environments, are going to transform our society.
Designers of these robots are not only required to
meet technical and legal challenges, but also address
the potential social, political, and ethical consequences
of their design choices. In this paper, we present a
workshop format with its related tools intended
for enabling speculation about such possible futures
and fostering reflection on potential socio-ethical
implications that might support/oppose these futures.
We report the results and discussion of one particular
workshop case, in which the implementation of two
particular robotic services for a city was envisioned
and questioned, i.e., surveillance and delivery of goods.
By discussing the results, we illustrate how such a
workshop format might be beneficial for setting the
agenda for a more conscious design of urban robots and
orienting future research towards meaningful themes
related to the emerging coexistence scenarios between
citizens and robots.
