Safety Design and Evaluation of Robots Coexisting with Humans by UML Modeling

点击翻译按钮获取中文摘要

I have proposed to introduce a UML modeling and an object-oriented approach to risk assessment of human-robot cooperating systems. Risk assessment is based on the international safety standard ISO 14121, and our UML-based, hierarchical unified model includes its elements of machinery, human, environments, origin and consequences of hazards and their types of group. By using the model, different viewpoints of safety factors such as an exhaustive list of hazards, scenario of tasks or potential hazardous situations can be derived from a unique dataset. Also, an iterative process of risk assessment and system modification are executed easily.
