Since robots with a high degree of adaptability and autonomy are now increasingly supporting humans both at work and in their private life, new applications are emerging, to make optimal use of robots that need to collaborate with humans towards common goals in different social settings. All these factors are pushing the growth of the social robotics market to new frontiers, whose ambition is to provide sophisticated and novel approaches to robot performance, social acceptability and sustainability. This workshop is designed to critically evaluate these questions from a transdisciplinary perspective, by exploring how social robots can affect and challenge trust in human social institutions and practices.
