System for laser printing and hole drilling on a building surface

A printing and drilling system for printing and drilling a target on a surface of a building comprising:

• a supporting unit movable in x, y and z axes;
• and
• a printing and drilling unit removably secured to the supporting unit, wherein the printing and drilling unit comprises:
• one or more laser position units for illuminating a working area containing the target,
• an imaging unit to scan the working area of the surface to capture images of the working area,
• a control unit to process the captured images, determine location coordinates of the target, and generate drilling data associated with the target,
• a laser generator for emitting a laser beam,
• a laser printing unit located at a base of a z axis and movable in x and y axes for emitting the laser beam generated from the laser generator to print the target,
• a laser path reflector in the laser printing unit that can deflect the laser beam to print one or more graphic marks as the target on the surface of the building, and
• an electric drill unit movable from a first position to a second position for drilling an anchor hole on the target.
