A robot controller executes an operating program, calculates a position and
posture of a robot, and sends the position and posture information to a
personal computer (PC). At the PC side, on the basis of this position and
posture information, animation display information of a work cell
including the position and posture of the robot is created and then sent
to a teaching pendant. In the teaching pendant, the animation display
information is received, and an animation image is displayed on a display
section. Until the operating program is terminated, this operation is
performed so that an operating animation of the robot is displayed on the
display section of the teaching pendant.
