Development of Automated Construction Work Execution Technology Using Laser Beams

This paper begins with a description of the dissemination of laser levels and the present status of measuring instruments . This is followed by an introduction of development evolution , equipment outline and the results of performance tests regarding a concrete levelling robot and an automatic level marker presented as the development examples of the proposed automated construction work execution technology using laser beams. It concludes with a description of the utilizability of laser beams to ensure automated/robotized on-site construction work.
