Abstract
A method for programming of a robot application comprising an industrial robot having a robot coordinate system, a tool having a tool coordinate system and a work object ( ) to be processed by the tool. The application is programmed by means of a position-measuring unit ( ) adapted for measuring positions relative a measuring coordinate system (db). The programming method comprises: selecting an object reference structure ( ) on the object, defining a mathematical model for the object reference structure, defining an object coordinate system (o ), providing measurements by the position-measuring unit on the surface of the object reference structure, determining the object coordinate system in relation to the measuring coordinate system (db) by best fit between said measurements and said mathematical model of the object reference structure.
