Abstract: A robot operation evaluation device includes: an operational state calculator for calculating an operational state of an evaluation region that is a movable region of a robot, based on an operational state of the robot; a shape-feature quantity calculator for calculating a shape-feature quantity depending on an operation direction of the evaluation region corresponding to the operational state calculated; and an evaluation value calculator for calculating an evaluation value representing a risk degree of the operational state of the evaluation region with respect to the operation direction, based on the shape-feature quantity.
