The Uncanny Workforce: Reviewing the Ethical and Technical Pathways for Social Robots in Healthcare

The fourth and fifth industrial revolution is revolutionarily seeing the emergence of Social Robots being adopted in hospitals, clinical, elderly care, and mental health settings with the potentials of reducing staff burden, delays, truancy and improving patient engagement. Interestingly, the 2020–2026 deployment data show a “pilot-to-purgatory” pattern as 63% of healthcare robot trials are discontinued after 6 months. This systematic review examines the ethical and technical pathways that will shape and determine whether social robots will become a trusted part of the healthcare workforce or remain as an “uncanny” novelty. Following PRISMA 2020 guidelines, 141 peer-reviewed studies from PubMed, IEEE Xplore, Scopus, and ACM 2020–2026 were analyzed. Findings were organized into 1.Ethical pathways: autonomy, privacy, accountability, and dehumanization; and 2.Technical pathways: affect recognition, long-term interaction, safety, and clinical integration. Results indicate that the “uncanny valley” is now less about appearance and more about role ambiguity, data governance, and brittle socio-emotional AI. A Proposal on an “Ethical-Technical Readiness” [ETR] framework is done and a 4-stage pathway: Tool- to- Companion- to- Teammate- to -Care Partner. The review concludes that healthcare will adopt social robots with open hands when and only when technical reliability is matched by ethical legibility.
