Research and Development Details and Results

TMC has developed three new standing scooter-type robots, and a balance training robot for preparatory drive training wherein a driver learns how to drive a standing scooter-type robot safely. Two of the new standing scooter-type robots are to be provided to Robot Safety Testing Center in 2013 where a set of safety tests is conducted according to ISO13482, and a new standing scooter-type robot and a balance training robot are to be provided to NCGG. The new standing scooter-type robots improved electronic and mechanical architecture design for size reduction and maneuverability, reliability of electronic system, usability of human-machine-interface, and environment resistance. The balance training robot utilizes a motion control technology which helps recovering most effectively the physical capability of elderly persons and disabled persons, and a pair of steps lower than conventional ones and a pair of wheels smaller than conventional ones, both of which make embarkation and disembarkation easiler for elderly persons and disables persons. Simultaneously, TMC has evaluated safety technology with Safety Testing Center using two conventional standing scooter-type robots and crash test dummies. Additionally, TMC has conducted real life tests of the conventional standing scooter-type robot with NCGG in a hospital environment. More precisely, two standing scooter-type robots are driven by medical staffs in NCGG, and risk associated with the operation is evaluated. The operation is observed by chosen patients and their opinions regarding the safety of standing scooter-type robot are collected. Based on the aforementioned data, TMC has been conducting risk assessments on the two robots. Lastly, TMC has been involved in the research and development of safety evaluation methods with Japan Automobile Research Institute (JARI), Advanced Industrial Science and Technology (AIST) and National Institute of Occupational Safety and Health. Through the research and development, TMC has advised test jig design and has provided an inspection software for electromagnetic compatibility test. TMC has, furthermore, provided maintenance service for the conventional standing scooter-type robot. For the evaluation of safety certification procedure, TMC has been conducting an investigation of safety standards and safety software tools as well as benchmarking of safety products. For the evaluation of severity of harm in using standing-scooter-type robots, simulations and experiments using a crash test dummy have been conducted partly with the help of NCGG and JARI, and the obtained knowledge will be utilized to refine the risk assessment of the standing-scooter-type robots.
NCGG, Depart. of Gerontechnology: We made an experimental setting with the suspension equipment to keep safety for user with integrating the results of test under practical situation and acquired surrounding techniques in order to make the potential risk during on board clearer in clinical situation. As the pilot study before the training with robots, we examine the effectiveness of balance exercise with using robots in the limited space under the frame for suspension and made fundamental data to make a guideline for application of license for users.
