THREE-DIMENSIONAL CURSOR AND OFF-LINE PROGRAMMING SYSTEM USING THE SAME

摘要

A three-dimensional cursor for designating the position and attitude of an object or a robot on a graphic screen that displays three-dimensional space, and an off-line programming system using the same cursor. Three line segments (X, Y, Z) that meet at right angles with each other in three-dimensional space are displayed as three line segment cursors on a display screen (1) and are allowed to move in the three-dimensional space, in order to designate three-dimensional position and attitude on the display screen (1) that displays the three-dimensional space. It is therefore possible to designate a position of three-dimensional space on the two-dimensional display screen (1). By designating the position and attitude of the arrangement of the object or the robot using the three-dimensional cursor, it is allowed to easily prepare a program for controlling the robot.
