| There is a growing interest in safety in wearable robot. From the results of the researches, it has been confirmed that a skin injury called a pressure ulcer is an injury that can occur in a wearable robot. Pressure ulcer has various symptoms and can be roughly divided into skin surface and muscle layer damage (Deep Tissue Injury). The conditions of DTI were derived from animal experiments and confirmed to be determined by the principal compressive stress. In order to find the relationship between the pressure of the skin surface and the principal compressive stress, simulation was performed. |

An analysis of fall injury reduction method for posterior fall of exoskeleton robot wearer |
|
Deukhwan Ahn, Kwan-Woong Gwak(Sejong University, Korea) |
| Fall-induced injury in the exoskeleton robot use is critical but the fall protection measures are insufficient. We propose an airbag system for the protection of an exoskeleton robot wearer from the fall and analyze the effect of injury reduction of the airbag system through the posterior fall simulation. |

Sunghoon Kim, Chang-Hwan Lee(Sejong university, Korea), Kwan-Woong Gwak(Sejong University, Korea) |
| A fall is a critical hazard that could cause serious injuries in the use of exoskeleton robots, hence we investigate the fall detection criteria for the exoskeleton robot use. Acceleration is often used an index to detect a person's fall and we investigate the applicability of this acceleration index to fall indicator to the exoskeleton robot use. For this, acceleration index for fall detection is investigated and computer simulate was conducted to verify the applicability of the acceleration index for the exoskeleton fall detection using the dummy model composed of human body and exoskeleton |

Validation on safety technical requirements of mobile transportation robots (load less than 120 kg) with ISO 13482 |
|
Su-Hyun Shin(Korea Institute for Robot Industry Advancement, Korea) |
| It specifies principles of risk assessment and risk reduction to help designers in achieving this objective with ISO 13482 and ISO 12100. These standards are based on knowledge and experience of the design, incidents, accidents and risks associated with autonomous mobile transport robot. Procedures are described for identifying hazards and estimating and evaluating risks during relevant phases of the robot life cycle, and for the elimination of hazards or the provision of sufficient risk reduction. |

A case study on risk assessment for personal care robot (Mobile robot) |
|
Naeun Kim, Seung-Taek Hong, Ki-yeop Sung, Gi-En Yu, Joon-ho Seo(Korea Association of Robot industry, Korea) |
| 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 frequency and intensity of the injury caused by them is risk assessment, which is a system that establishes reduction measures. 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. |
