How does the surface curvature tracing system work?
A car (or any other object, a snowboard, for example) is put in front of airbrush-robot. An image position on a car body is determined. The co-ordinates of 4 marginal points of an image in robot co-ordinates system are determined (0:0 point is considered as upper left point of the robot). Further the points (X- and Y-coordinates of the points), in which the robot measures a distance from an X-axis to the surface, are set on an image area (thereafter the points will get 3 co-ordinates X, Y and Z). A matrix is set up of points (N number of lines, each consisting of M number of points), which is then saved as Body Data File by the robot. When in printing mode a Body Data File is up-loaded the robot is printing from a constant equal (10mm) distance to the surface, avoiding roughs by available free movement (Z=200~450mm).
