Development of Standard Test Methods (STM) for nuclear emergency response robot is one of the research themes of Naraha Remote Technology Development Center. For two years after the accident at Fukushima Daiichi, more than thirty robots have been deployed to the Fukushima Daiichi NPS. To clarify the functions and requirements to be evaluated for nuclear emergency response robots, it is important to analyze the objective of robot development. The functions and requirements have become clear, based on the time analysis, and failure analysis of such robots. From the time analysis of operation using Quince, more than 70% are moving in time, but 10% have uncertain stops. From the failure analysis, 4 out 5 failed robots have trouble related to communication with robot control. Some STMs could be used to evaluate the function and requirements. JAEA is planning to develop the additional STM at the Naraha Remote Technology Development Center.
