A robot controller configured to control an operation of a robot, the robot controller comprising:

• a depth acquisition section configured to acquire a group of depth data representing depths from a predetermined portion of the robot to a plurality of points on a surface of an object located around the robot;
• a robot position acquisition section configured to acquire three-dimensional position information of the predetermined portion;
• a depth map generator configured to generate depth map information including three-dimensional position information of the plurality of points with reference to a installation position of the robot as an origin, with using the group of depth data and the three-dimensional position information of the predetermined portion;
• and
• an interference region setting section configured to estimate a range occupied,by the object from the depth map information, and set the range as an interference region for the robot.
