The 9th International Symposium on Automation and Robotic in Construction June 3-5,1992 Tokyo, Japan ROBOT ORIENTED MODULAR CONSTRUCTION SYSTEM

The tasks that the construction industry should be accomplished at construction sites today and in the future are the saving labor and the reduction of the construction period. To accomplish these challenging objectives, automatic and robotic construction systems of construction work have been actively by construction industry in Japan. However, a basic concept of a proposed automatic and robotic construction system is equivalent to those of a conventional construction system. What has so far been proposed is mere automation and robotization of mechanism used and manual work. Innovations of this, however, will hardly help us accomplish such challenging objectives that are the saving labor and the reduction of the construction period. In the focusing of these circumstances in the construction industry, authors have studied a construction system by a new logic that is based on the concept of a assemble-line system instead of the conventional final-line system in construction work. With a view to substantiating our new logic, a mock up model test was carried out with full-size space module unit which was fabricated in the factory line on site. As a result, it was cleared that one floor of the model building could be completed in one day with one-fourth or less the labor that would otherwise have been required to the conventional system.
