Towards Automated Welding in Big Shipbuilding Assisted by Programed Robotic Arm Using a Measuring Arm
This paper presents an automated robotic welding system adapted for shipbuilding in large shipyards. This solution has been devised in the shipyard of Navantia located in the south of Spain, in the context of ROBOT FASE II R&D project. It also presents the human teams that have developed this welding system. The article explains the 3 parts that make up the welding system. The location of the robotic welding arm of the Fanuc brand is detailed in the first part. In addition, the gantry and spatial coordinate axes are described and indicated where the robotic arm is housed. The second part contains the system capture of the coordinates in the space for the reading of the singular points to be soldered. These points are measured by a portable measuring arm. The last part is composed of the system of communication between the different parts throughout the computer. The computer is responsible for synchronizing the measuring arm and the robotic welding arm by translating the points to be soldered.
Development of multi welding robot system for sub assembly in shipbuilding
Abstract In an effort to increase a productivity of welding process and to reduce the impact to workers from industrial disaster, the research in the field of welding automation is sharply increasing in shipbuilding industry. DSME had developed and successfully applied a welding robot system for grand assembly line in OKPO shipyard in 1997 and has recently developed multi welding robot system for the sub assembly line. This study describes the essential parts of welding automation for the sub assembly process of a hull when using industrial robots. Study includes description of auto detection process of work-pieces, off line program (OLP), host control program and high speed welding method.
Energy based memory regulating system
The system by which information is stored in and retrieved from memory has always been a topic of great interest to scientists. how to build a basic structure of memory and its operating policy are very important for maintaining fresh memory for powerful functions of intelligent system. Focusing on memory management we propose memory regulating system based on energy term. Memory regulating system has a maintaining policy structuring the memory in the perspectives of short-term memory and long-term memory view. We apply this system to Virtual memory and test with sample data.
