1. A method for robot arm locus control comprising the steps of:
- a. teaching the robot coordinates of a first three representative points and first work points of an object to be worked on by the robot;
b. teaching the robot coordinates of a second three representative points of the object when a change in the relative position of the robot and the object occurs, said second representative points corresponding to said first representative points;
c. calculating coordinates of second work points from data representative of the relative positions of said first representative points and first work points and said second representative points, so that said second work points define a locus at a position different than that of said first work points, said second work points corresponding to said first work points;
d. using said coordinates of said second work points to provide commands for the robot; and
e. controlling the robot to follow said commands.

Abstract
In a robot locus control metod, the coordinates of first three representative points and first work points of an object to be handled by a robot are taught to the robot, when the relative position of the robot and the object is changed, the coordinates of second three representative points corresponding to the first three representative points are taught, and the coordinates of second work points are calculated from the relative position of the first three representative points and the first work points and the second three representative points, thereby to command the robot working locus.

12. A method for robot arm locus control comprising the steps of:
-
a. providing to the robot numerical values of coordinate data of first work points and a first three representative points of an object to be worked on by the robot; b. providing to the robot values of coordinate data of a second three representative points of the object when robot trajectory based on numerical coordinate data of the first work points deviates from actual work lines of the object, said second three representative points corresponding to said first three representative points; c. calculating values of second work point coordinate data from relative positions of said first three representative points, said first work points and said second representative points, said second work points corresponding to said first work points; d. using values of said second work point coordinate data to provide commands for the robot; and e. controlling the robot to follow said commands.
