Abstract: A method of selecting a teaching point program in a three-dimensional graphical representation of a workcell includes the steps of generating the three-dimensional graphical representation of the workcell, calculating a three-dimensional boundary box for each teaching point program associated with the workcell, converting each boundary box to a two-dimensional boundary area, and recognizing which boundary areas overlap a selected area drawn over a two-dimensional display screen. Each boundary area that has been recognized as overlapping the selected area is identified to a user and presented in a list if multiple candidate boundary areas are recognized and identified. The user may then edit those teaching point programs identified as being associated with the selected area.

Abstract: When a robot language is to be displayed and edited, a teaching apparatus or a programming pendant heretofore displays intermediate code of the robot language as expressed by characters. The operator cannot intuitively recognize motions of the robot, needs time to master the robot language, and is required to actually move the robot to confirm the correctness of the program after the robot has been taught. According to the present invention, a robot language processing apparatus includes a display device for graphically displaying a picture and designating a position in the displayed picture with a pointing device, a memory for storing a robot program, a graphical language processor for displaying an operation interval and an air-cut interval as successive lines on the display device by referring to the robot program, and controlling the display device to display the type of an operation detail at either one of the lines when the either one of the displayed lines is designated by the pointing device.
