Research and development of safety level verification technology

Introducing service robots into fields of nursing, welfare, and housework is expected to solve issues in our rapidly aging society. Such introduction, however, requires developing safety technologies for employing robots near ordinary people. This project seeks to develop methods to verify and validate service robots by globally acceptable criteria. In fiscal year 2011, we achieved five major results.
First, we designed a format of risk-assessment sheets for evaluating risks and harm during risk assessments prior to designing the service robots. This format provides examples of risk evaluation and risk reduction strategies. We improved the risk assessment methods proposed last year, according to results of discussion with robot manufactures who conducted risk assessments using our proposal.
Second, we improved the test methods for verification tests of safety requirements, which we developed last year. (1) Environment resistance test and EMC test: Methods to verify the proper operation of safety-related systems under various conditions including vibration, humidity, temperature and electromagnetic environments. (2) Dynamic stability test during travel of mobile robot: Methods to verify the stability during sharp turns, acceleration, and deceleration on test surfaces representing multiple conditions of robot applications. (3) Environment detection test and obstacle detection test: Methods to verify performance of obstacle detection and collision avoidance in various environments including strong sunlight. (4) Collision test: Methods to verify human injury levels in case of collisions between robots and obstacles including human. We also discussed some criteria of mechanical parameters that represent human injury levels. (5) Human-robot contact test: Methods to verify safety of wearable robots during physical human-robot contact and interaction. (6) Functional safety verification test: Test methods to verify the proper operation of safety-related control functions. (7) Summarizing the results, we documented a draft of test method for an international standard proposal.
Third, using these methods, we tested four types of robots provided by manufacturers in "Project for practical applications of service robots" to obtain information for confirming the applicability of these methods.
Fourth, we drafted a safety-certification system according to international standards including ISO13482, which is being discussed as an international standard for personal-care robots.
Fifth, we built a basic database of information on safe design, safety verification, and validation as well as safety laws and regulations. In addition, we developed a development support tool for systems with functional safety.
To encourage the application of the project results worldwide, we held discussions with parties involved in service robot research and development and provided information for international standards through domestic meetings.
