Abstract: The invention relates to a method for automatic measurement and for teaching-in of location positions of objects (11) within a substrate processing system (20, 26) in which a sensor carrier (1) is moved by means of a robot end effector (24). Sensor units (2, 3, 4, 5a, 5b) of the sensor carrier (1) are moved along straight movement lines (B1, B2, B3) across the edges (10a, 10b) of the object (11), wherein each of the sensor units (2, 3, 4, 5a, 5b) output at least one sensor signal which changes its value upon detection of an edge (10a, 10b). From the positions of the signal changes along the respective straight movement lines (B1, B2, B3), the location position of the object (11) is determined.
