和文要約和文要約等以下本編抜粋:1. 研究開発の内容及び成果等 (1) 研究開発の背景と目的 生活支援ロボットは、介護・福祉、家事、安全・安心等の生活分野における社会的課題の解決策の一つとして期待されている。しかしながら、不特定多数の人が関与する等の使用環境下で稼働する生活支援ロボットは、対人安全技術が確立されていない。そこで、本事業では、認証機関・試験機関が、安全性基準に関する国際標準等にもとづいて生活支援ロボットの安全性を検証することを想定して、検証の手法を開発する。
英文要約Project for practical applications of service robots
Developmental item [1]
Research and development of safety level verification technology
Introduction of service robots into fields of nursing, welfare, and housework is expected to solve issues in the fast-aging society. Such introduction, however, requires developing safety technologies for use of robots near ordinary people. This project seeks to develop methods of verification and validation for the service robots by globally acceptable criteria. In fiscal year 2010, we achieved four major results.
First, we developed some judgment indexes for evaluating risks and harm during risk assessments prior to designing the robots. Although risk assessment methods are standardized for machinery and electrical/electronic/programmable electronic systems, the methods suitable for service robots should be developed.
Second, we developed equipment for verification tests of safety requirements. An obstacle approaching simulation system was developed for obstacle detection tests. An artificial sun-light system was introduced for environment detection tests. Test surfaces representing multiple conditions of robot applications were developed for traveling stability. A base model of the evaluation system for a wearable robot was developed for safety during physical human-robot contact and interaction. Test methods for human-machine interfaces and functional safety were also being developed. Test facilities for representing collisions between robots and obstacles were developed, and test facilities for endurance and electro-magnetic compatibility were also introduced. Using this equipment, we tested current models of robots provided by manufacturers in "Project for practical applications of service robots" to obtain information for developing the test methods and criteria for verification.
Third, we studied safety validation methods and drafted a list of safety requirements for service robots in order to establish a safety certification system according to ISO13482, which is being discussed as an international standard for personal care robots.
Fourth, we started to build a data base of information on safe design, safety verification, and validation as well as safety laws and regulations. In addition, we developed a draft version of a development support tool for systems with functional safety.
To encourage the results of this project to be usable worldwide, we held discussions with parties involved in service robot research and development and provided information with domestic meetings for international standards.
