ABSTRACT

A mobile printing robot system for printing a construction layout. The method
addresses a problem that occurs when there is a loss of a tracking lock to an
absolute positioning device, such as a total station. In a construction site,
a line of sight between a mobile robot and an absolute positioning device may
be lost when the mobile robot moves into a shadowed region behind an obstacle,
such as a column. The mobile printing robot may use its local sensor data to
continue to print until a maximum estimated position is reached. The mobile
robot may also provide position updates to the absolute positioning device to
aid it to regain a track lock when the mobile robot emerged from the shadowed
region.
