Automation and Robotics in Construction: Japanese Research and Development

Abstract

Abstract : The U.S. Army Corps of Engineers' construction program needs to reduce costs and improve quality. Productivity is decreasing in the U.S. construction industry, which is the opposite of the manufacturing segment, where productivity is improving. One reason for this is the use of advanced computer and machine technologies. The introduction of advanced construction technologies is particularly evident in Japan. This report presents information gathered during a study of Japanese construction industry. Much of the information was gained through interviews with company representatives. Particular focus was placed on identifying the methodology and organization that the Japanese use in their research and development for automated construction systems, including development of robotics. The information gathered shows that the Japanese are considerably ahead of other countries in their applied research towards construction automation. The organization and methodology that each Japanese company used toward this effort seem very similar. The differences between Japanese companies and their U.S. counterparts as they affect the introduction of new construction technologies are discussed. (kr)
