COCSY II: CAD/CAM Integration for On-Site Robotics

摘要

This paper discusses the need for automatic data extraction, processing, and transfer [computer-aided design and computer-aided manufacturing (CAD/CAM) interfacing] between the design and construction phases as a key element in computer-integrated construction (CIC). The CAD/CAM interface eliminates the need for manual interfacing between these two computer-aided phases. The CAD/CAM interface improves the process of the constructed facility realization by eliminating the manual data processing and thereby reducing many sources of errors. It also makes the process more cost-effective because it reduces labor inputs, especially those presently invested in robot programming. A model for automatic data extraction, processing, and transfer is proposed for the tile-setting paradigm. The model generates construction management data as well as data needed for automatic on-site construction (robotics). The model is implemented in the AutoCAD and AutoLISP environments. The model and the implementation system were tested in the laboratories with a scaled robot adapted to perform interior finishing tasks.
