  Recent research in affective robots has recognized their potential in
supporting human well-being. Due to rapidly developing affective and artificial
intelligence technologies, this field of research has undergone explosive
expansion and advancement in recent years. In order to develop a deeper
understanding of recent advancements, we present a systematic review of the
past 10 years of research in affective robotics for wellbeing. In this review,
we identify the domains of well-being that have been studied, the methods used
to investigate affective robots for well-being, and how these have evolved over
time. We also examine the evolution of the multifaceted research topic from
three lenses: technical, design, and ethical. Finally, we discuss future
opportunities for research based on the gaps we have identified in our review
-- proposing pathways to take affective robotics from the past and present to
the future. The results of our review are of interest to human-robot
interaction and affective computing researchers, as well as clinicians and
well-being professionals who may wish to examine and incorporate affective
robotics in their practices.
