The utilization of robots in programming education students the interest and motivation of learning. But at the same time the robot is required that understanding of the structure and understand the internal program(programming). So what problems are caused by error or if the student has difficulty identifying. The purpose of this study is the use of simulation tool in robot programming education possibilities will want to see. Elementary school students to analyze the possibility of non-simulation tool and simulation tool was applied. And usability evaluation and simulation tool, the survey recognized the potential of the education were analyzed. As a result, the usability of between simulation tool and non-simulation tool and there was no difference. And student can preview the results of programming and simulation tool can easily identify errors for recognizing the positive respectively. Based on this results, simulation tool can be utilized in robot education.
