  Human-Robot-Interaction (HRI) research is typically built around the premise
that the robot serves to assist a human in achieving a human-led goal or shared
task. However, there are many circumstances during HRI in which a robot may
need the assistance of a human in shared tasks or to achieve goals. We use the
ROBO-GUIDE model as a case study, and insights from social psychology, to
examine how a robot's personality can impact on user cooperation. A study of
364 participants indicates that individuals may prefer to use likable social
robots ahead of those designed to appear more capable; this outcome reflects
known social decisions in human interpersonal relationships. This work further
demonstrates the value of social psychology in developing social robots and
exploring HRI.
