Claim 7:
8. A method for forming a controlled safety area for a manipulator wherein the controlled safety area is monitored in order to prevent human entering to the controlled safety area to be hit by the manipulator working within the controlled safety area, and wherein the method comprises method steps of:
dividing the controlled safety area in to a high grade safety area in between an at least one laser scanning wall formed by a laser scanner, and to low a grade safety area outside the at least one laser scanning wall;
detecting humans in at least the low grade safety area around the high grade safety area by an at least one area detecting laser scanner;
controlling the at least one laser scanner to form a virtual door to the at least one laser scanning wall through which a human in the low grade safety area detected by the area detecting laser scanner can safely enter from the low grade safety area to the high grade safety area.
