Personalization, choosing the robot action best suited to each child, can be framed as a recommendation problem, and a recently proposed recommender-system framework for social robots offers a principled approach through user profiling, ranking, and responsible computing. Instantiating it, however, is blocked not by the model but by the data, which is hard to gather. A child’s state shifts within and across visits, so no fixed description of the user holds. Within a session, the few signals of whether the robot’s actions helped are weak and indirect. Across sessions, children are rarely seen more than once, and anonymization breaks the identity needed to link visits. Because care cannot be randomized, existing data is observational, biased toward whatever was already done. Each is a familiar recommendersystem problem, and we propose four data principles in response: an integrated profile, effectiveness signals, linkable coverage, and an exposure record logged at collection time. We identify which of these principles each capability requires, and frame them as concrete guidelines for data collection.  \nI. INTRODUCTION  \nEnsuring the well-being of children is a priority shared by parents, educators, and clinicians, and it depends not only on a child’s physical care but on how the people around them respond to their needs. This is most acute in clinical settings, where illness and medical procedures place children under stress. Social robots are increasingly brought in to offer companionship and emotional reassurance, and to help children understand what is happening to them [2]–[4] . However, children vary widely in developmental stage, anxiety, prior knowledge, and language, so effective support must be personalized to each child [5], [6] .  \n∗These authors contributed equally and are co-first authors.  \n1J.

For instance, at Hospital Virgen del Rocío in Seville, Spain, the social robot Haru [1] provides companionship and conducts anxiety screening for children undergoing cancer treatment [7] . Many of these children, such as those with leukemia, return repeatedly over months of care, and their anxiety, understanding, and emotional state differ from one child to the next and shift from visit to visit. To effectively support them, the robot must adapt both to the individual child and to how that child changes over time.
