離床アシストロボット“リショーネPlus”の安全技術開発

抄録

Human safety is essential for nursing care robots, which have codependent relationships with human. The international safety standard for personal care robots (ISO 13482) is the key to human safety. In this standard, protective measures for risk reduction, which are implemented using the control system, has to be developed based on functional safety standard. A lot of time is needed to do that. Initial investment for developing nursing care robots has to be held down because they are generally low-volume production and it is difficult to investment recovery. In addition, users demand low-cost products. Therefore, it is very important to achieve the functional safety suitable for "low-volume production" and "low cost product", which are required for nursing care robot. Under such circumstances, we developed the rise assisting robot “Resyone Plus”, based on such a concept of functional safety, which can realize "low-volume production" and "low cost product". And we acquired the certification of ISO 13482 about this robot and realized its commercialization. This paper reports a concrete example of how to develop it.
