Abstract
In this paper, we estimate the human mental model to establish a guiding principle for control system for autonomous mobile robot. As a first step, we have analyzed the avoidance behavior against an obstacle by the experiment of remote control operation of the robot using the simulator. And we investigated the effect to behavior from varying the amount of data to be presented to subjects. As a result, the operators tend to perform avoidance behavior considering the distance to the obstacle and the appearance of the obstacle. We considered a simple model of avoidance against an obstacle and generated the locus similar to operator's that.
