[Purpose] To provide a table mover capable of causing a table unit smoothly along slide rail.

[Solution] A table mover 38 includes a table unit 40 including a table carriage 49 to support a table 48, and the table unit40 is movable in sub-scanning directions X along a first slide rail 51 fixed to a left side frame 64 and a second slide rail 52 fixed to a right side frame 65. The table carriage 49 includes: a first left fixer 49DA to which a left fixing bracket 56 coupled to the left slide member 81X to be engaged with the first slide rail 51 is fixed and a first right fixer 49EA to which a right fixing bracket 57 coupled to a right slide member 82X to be engaged with a second slide rail 52 is fixed. The first left fixer 49DA is elastically deformable in main scanning directions Y relative to the left side frame 64.

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.
