What Are Physical Assistant Robots? A Rapid Evidence Review to Make a Case for Clearer Definitions

Abstract

Physical Assistant Robots (PAR(s)) are increasingly ubiquitous robots that assist humans with various physical tasks, including walking, eating and dressing. However, there is lack of definitional clarity when it comes to PARs, with ambiguity as to how these robots are construed. This results in potential issues for user safety and for manufacturers’ liability. Employing a rapid evidence review, this paper highlights the discrepancies associated with the understanding of PARs in the literature, and shows the lack of consensus regarding the meaning of PARs. The preliminary results indicate the wider ramifications that these discrepancies can cause in terms of safety for users and regulatory compliances for manufacturers. The authors conclude by advocating for a clearer understanding of PARs to ensure necessary safeguards, and by outlining how further research will be conducted to this end.
