13. 2 Risk Assessment and Optimization of Safety Protective IMleasures on Robot controlled Cell Production system Kazuya Okada Ikuo Maeda Akihito Sugano Nobuo Higuchi Yoshitaka Tsuji and Toshihiro Fujita Abstract Production systems in FA industry employ more robots in recent years in order to improve the productivity and efficlency of operation and operators are increasingly required to work in collaboration with Various types of robots Ensuring the safety for operators is a matter of great importance in today s Human Machine Interface HMI environments which must be constructed with ergonomically designed control systems Furthermore HMI environments need to be provided with safety measures that reflect the inherent safety concepts of the international standard for safety of machinery ISO 12100 In this paper we report on the risk assessment on our Robot controlled Cell Production System and also the optimum safety measures achieved by safety human machine interfaces Keywords Robot controlled Cell Production System inherent safety ISO12100 safety human machine interface risk assessment 1 FA Factory Automation
