Bài viết này nghiên cứu về phát triển một robot tự động đánh dấu. Để hàn "Dự thảo Mark" cho một con tàu, một hệ thống hàn tự động, được gọi là Robot tự động đánh dấu, được phát triển. Phần mềm và phần cứng của hệ thống được thiết kế cho mục đích này. | TẠP CHÍ PHÁT TRIỂN KH CN TẬP 11 SÓ 03 - 2008 STUDY ON DEVELOPMENT OF AN AUTOMATIC MARKING ROBOT Le Hong Loan Pham Dang Khoa TranThien Phuc Nguyen Tan Tien University of Technology VNU-HCM Manuscript Received on November 01st 2007 Manuscript Revised March 03rd 2008 ABSTRACT This paper studies on development of an automatic marking robot. To welding the Draft Mark for a ship an automatic welding system called automatic marking robot is developed. Software and hardware of the system are designed for this purpose. Experiment has been done to verify the proposed solution. 1. INTRODUCTION Outside of the ship there are some kinds of mark used to describe some properties of the ship such as name of ship port of registry draft mark .as shown in . In ship building manufacturers this work has been done by skill welders. However manual work welding is poor work surroundings and time-consuming. To overcome these disadvantages some researchers focus to design an auto welding robot which can carry out the task with high speed and accuracy degree. . Ryu et al. 1 in Samsung Heavy Industry had developed SR-MARK robots to weld draft mark automatically. There are two kinds of SR-MARK robot SR-MARK I uses for welding draft mark on the flat surface and SR-MARK II uses for welding draft mark on the curved surface. Both of them have been experimented successfully in laboratory. Fig1.

The development target to 2010 is regarding and improving the shipyards in order to have technology equal to the ASEAN shipbuilding industry while the localization rate of domestically made products will rise to 60-70 percent of the products.
