General evaluation method of safety strategies for welfare robot-evaluation of safety design by quantifying dangerousness

摘要

The general evaluation method of various kind of safety strategies for welfare and human care robots is first proposed in the world. The impact force and impact stress are chosen as safety evaluation values to quantify safety. The dangerous indexand safety index are defined to make quantitative evaluation of the effectiveness for each safety strategy. Moreover this method enables us to know the contribution of each safety strategy to the overall safety performance of welfare robot. As a resultdesign optimization of the safety robot is discussed successfully.
