Abstract
A vehicle body is assembled in a number of stages each including robots which are automatically adjusted to move and secure work pieces such as panels to a basic body member or chasis. One of the stages includes a measuring arrangement which scans the assembled unit with laser beams to determine if the required tolerance have been set. In the event of deviations beyond permissible limits the appropriate correction is derived and fed back to the stage wherein the securing operation in question occured.
