Abstract: The present invention, by manually operating a robot and memorizing a position of the extremity of the robot, teaches a reference point representing a representative position and orientation on a moving path and a relative position of an operating position of a robot extremity in operation from the above-mentioned reference point, and designate a path of a moving position of the robot extremity in operation by an array of the reference points, and teachings of the moving path and a gripping position can be separated each other, and an accurate and easy teaching is enabled.

Abstract: The interference avoiding system is provided with an automatic correcting means for correcting a code string programmed for each robot, so that the communication and the waiting processes to check the interference are automatically inserted. In order to check the interference, a target position is transmitted to a checking device immediately before the robot starts operating, thereby to check the interference area by the checking device. Instead, data of the interference area is fed to a robot controller at the start of operation, and the communication is established only when the robot moves from inside to outside the interference area or vice versa. An operation command for the robots is selectively corrected automatically, that is, an operation command to move the robots in a direction not related to the interference direction is not corrected.

Abstract: The disclosure is directed to a control arrangement for an industrial robot, which is capable of teaching a continuous path operation, and playing back the operation thereby. According to the present invention, it is so arranged that, in a process for automatically memorizing the operating path information of the industrial robot by direct teaching, data for the operating distance on the taught path is also computed so as to be stored together with positional data, and during play back of the function, interpolation is effected based on the operating distance data, whereby the robot is caused to function at a predetermined speed, according to the path at the teaching, and thus, it becomes possible to effect the playing back operation without being influenced by the operating speed during the teaching.
