1. A method for facilitating calibration of a robot cell including one or more objects ( 8 ; 52 ) and an industrial robot ( 1 , 2 , 3 ) performing work in connection to the objects, wherein the robot cell is programmed by an offline programming tool including a graphical component ( 22 ) for generating 2D or 3D graphics based on graphical models of the objects, and the method comprises: storing for each of the objects a sequence of calibration points ( 54 , 56 , 58 ) including information on a desired order in which the calibration points should be visited during calibration automatically generating a sequence of images ( 60 , 65 , 66 ) that shows the order in which the calibration points are to be visited, each of the images including a graphical representation of the object to be calibrated and the calibration point points in relation to the object, transferring the sequence of images to the robot, and displaying said sequence of images to a robot operator during calibration of the robot cell so that for each calibration point a view including the present calibration point and the object to be calibrated is displayed to the robot operator.
