Social Robotics poses tough challenges to software designers who are required
to take care of difficult architectural drivers like acceptability, trust of
robots as well as to guarantee that robots establish a personalised interaction
with their users. Moreover, in this context recurrent software design issues
such as ensuring interoperability, improving reusability and customizability of
software components also arise.
Designing and implementing social robotic software architectures is a
time-intensive activity requiring multi-disciplinary expertise: this makes
difficult to rapidly develop, customise, and personalise robotic solutions.
These challenges may be mitigated at design time by choosing certain
architectural styles, implementing specific architectural patterns and using
particular technologies.
Leveraging on our experience in the MARIO project, in this paper we propose a
series of principles that social robots may benefit from. These principles lay
also the foundations for the design of a reference software architecture for
Social Robots. The ultimate goal of this work is to establish a common ground
based on a reference software architecture to allow to easily reuse robotic
software components in order to rapidly develop, implement, and personalise
