points of a path by means of robot control rc to that end in this embodiment of the present invention the path is suitably recorded in a description in the world coordinates as well as in the robot coordinates of robot r 1 and these two sets of data are stored as a graph as depicted in fig4 the robot control rc can output at any time where sensor s is located in the robot coordinate system the sensor processing device pa requests the path of robot control rc for each measuring point of sensor s and translates it into the world coordinate system by means of a previously determined table this graph may consist of discrete points or may depict a composite function that is obtained through appropriate interpolation of the measuring points an indispensable requirement for the method according to the invention is that the path must be replicated precisely to that end a compensation step is performed regularly u2014 in the case of this embodiment before the measurement of every additional object of measurement 200 reference body 300 is used for this reference body 300 is measured regularly reference body 300 is constructed in such a way that its dimensions do not change if a different point cloud is obtained when measuring the reference body than in an original measurement this is attributed solely to changes in the kinematics of the robot r 1 the kinematics of the robot are subject to so called internal influences such as wearing of the joints as well as to external influences such as changes in the ambient temperature which influence the dimensions of the.
