Abstract
Although groups of robots are expected to interact with groups of humans in the near future, research related to teams of humans and robots is still scarce. This paper contributes to the study of human–robot teams by describing the development of two autonomous robotic partners and by investigating how humans choose robots to partner with in a multi-party game context. Our work concerns the successful development of two autonomous robots that are able to interact with a group of two humans in the execution of a task for social and entertainment purposes. The creation of these two characters was motivated by psychological research on learning goal theory, according to which we interpret and approach a given task differently depending on our learning goal. Thus, we developed two robotic characters implemented in two robots: Emys (a competitive robot, based on characteristics related to performance-orientation goals) and Glin (a relationship-driven robot, based on characteristics related to learning-orientation goals). In our study, a group of four (two humans and two autonomous robots) engaged in a card game for social and entertainment purposes. Our study yields several important conclusions regarding groups of humans and robots. (1) When a partner is chosen without previous partnering experience, people tend to prefer robots with relationship-driven characteristics as their partners compared with competitive robots. (2) After some partnering experience has been gained, the choice becomes less clear, and additional driving factors emerge as follows: (2a) participants with higher levels of competitiveness (personal characteristics) tend to prefer Emys, whereas those with lower levels prefer Glin, and (2b) the choice of which robot to partner with also depends on team performance, with the winning team being the preferred choice.

Summary
As robots become a more common and pervasive technology in our society, they will slowly become common aids in our everyday activities. It is inevitable that humans and robots will engage in cooperative activities as teams in the near future (Coradeschi and Saffiotti, 2006). For this to be possible, robots must be endowed with the necessary competencies that enable social interaction with humans to occur. Several works have explored different ways of interacting in teams comprising both robots and humans (Chang et al, 2012; Eyssel and Kuchenbrandt, 2012; Fraune et al, 2015). We contribute to this literature, exploring the social competences necessary to build successful teams of humans and robots. We study multi-robot and multi-person interactions, investigating people’s preferences toward robots with different goals and exhibiting different social behaviours
