Abstract
A system and method for printing an image on a surface using a printing robot, wherein data from an internal position determination system of the robot as well as data from a reference system comprising a stationary reference external to the robot are used to calculate an estimate of position, velocity and acceleration of the print head relative to the surface. As print head is moved along the surface during printing, i.e. as the print head is moved while ink is ejected from nozzles of the print head, the positioning of the print head and activation of nozzles of the print head are controlled based on the estimate.
