Abstract:
The invention relates to a method and a system for the high-precision positioning of at least one object in a final location in space. An object (12) is gripped and held by the industrial robot (11) within a gripping tolerance. A compensating variable, which corrects the gripping tolerance, is determined for the industrial robot (11). The object (12) is adjusted with high precision into a final location by the following steps, which repeat until reaching the final location at a predetermined tolerance: recording of image recordings by recording units (1a, 1b); determining the current location of the object (12) in the spatial coordinate system from the positions (Pa, Pb) of the recording units (1a, 1b), the angular orientations of cameras (2a, 2b) of the recording units (1a, 1b) which are detected by angle measuring units (4a, 4b), the image recordings, and the knowledge of features (13) on the object (12); calculating the location difference between the current location of the object (12) and the final location; calculating a new target position of the industrial robot (11) in consideration of the compensating variable from the current position of the industrial robot (11) and a variable which is linked to the location difference; adjusting the industrial robot (11) into the new target position.
