User-Friendly Robotics 2-Interfacing Robotics with any user

In this paper, the second part out of three, we continue presenting the route of our long experience in interfacing AI and Robotics with the public. This paper, in particular, highlights a crucial step we experimented when creating computer based software architecture so to let the common user easily interact with complex behaviour robotics. We define such an approach User-Friendly Robotics, and we hereby describe the principles and the techniques we used to evolve its methodology reporting here the most important case studies we went through, as examples. We then analyse the impact of such method on both science and educational field. Finally, we discuss how this User-Friendly Robotics approach leads to solutions that fit particular purposes in society and lead to useful user interaction with technological developments.
