A case study on risk assessment for personal care robot (Mobile servant robot)

Abstract

As the use of personal care robots increases, cases of damage have occurred and it is urgent to take countermeasures against them. The most basic method to identify the hazardous risk factors and estimate the likelihood (frequency) and severity (intensity) of the injury or illness caused by them is risk assessment, which is a system that establishes reduction measures (Guidelines for the Assessment of Workplace Hazards, 2017). In this study, risk assessment was conducted according to the safety requirements for robots presented in the international standard. As a result, we analyzed the risk assessment for improving safety by deriving measures and measures for reducing risks. The results of this study can be used as a basic data for the safety evaluation to lower the risk to the level required by the standard and receive the safety certification of the personal care robot in the future.
