Welding Robot Applications in Shipbuilding Industry: Off-Line Programming, Virtual Reality Simulation, and Open Architecture
'IntechOpen', 2021Co-Authors: Chang-sei Kim, Keum-shik Hong, Yong-sub HanAbstract:This chapter described the welding Robot system in a shipbuilding industry and the PCbased off-line programming system. The welding Robot system is very helpful not only to increase productivity but also to solve worker\u27s health problem. The developed off-line programming system provides a Robot simulation, a block arrangement simulation, optimal Robot traveling path generation, and automatic Robot program generation. Because graphic environments are made in the VRML, developed off-line programming is highly compatible with other software, which fact allows the use of off-line programming on the Internet

Welding Robot Applications in Shipbuilding Industry: Off-Line Programming, Virtual Reality Simulation, and Open Architecture
Industrial Robotics: Programming Simulation and Applications, 2006Co-Authors: Chang-sei Kim, Yong-sub Han, Keum-shik Hong, Daewoo ShipbuildingAbstract:The shipbuilding industry is steadily advancing by introducing Robots to its work fields for increases in productivity and improvements in working conditions (Nagao et al, 2000). However, the shipbuilding company still faces with the worker’s health problem, an increase of aging workers, a shortage of skilled workers, and environmental protection related issues. Therefore, advanced Robotic manipulator is still required to overcome these problems. And, how to apply commercial Robotic system properly to meet the production purpose in the shipyard is a key research topic for shipbuilding engineers. The shipbuilding process is mainly divided into design, cutting, welding, assembling, grinding, blinding, and painting process. Among these manufacturing processes, welding is the most crucial, expensive, and time-consuming process. For that reason, welding Robot Applications have yielded a big productivity improvement in hull assembly welding and have reduced work-related musculoskeletal disorders of workers. In this chapter, the results of our work in the development of a welding Robot system and a PC-based off-line programming for welding Robot application on assembly lines in shipbuilding are explained. Also, a methodology of implementing PC-based off-line programming on users PC is presented. The off-line programming is a system that comprises Robot’s simulation, Robot programming, and other functions such as monitoring, scheduling, etc, that makes users operate Robot system easily. The off-line programming is essential for welding Robot system in shipyard to prepare Robot program and then to shorten production time. Currently, the operation of industrial Robots is through either on-line teaching or off-line programming (Choi & Lee, 2003; Carvalho et al., 1998; Craig, 1986;). On-line teaching is, by definition, a technique of generating Robot programs using a real Robot system, whereas offline programming is a method using simulations that are set up in advance. On-line teaching may be suitable for jobs for which a Robot only needs to repeat a monotonous motion using one pre-written program that applies to identical sizes or objects. But, in such work places as shipbuilding, where the shape and size of workpiece are various (i.e., there are more than 1200 different shapes of workpieces for grand-assembly, if we account the size of these different shaped workpiece, we may not count the different kind of workpieces. Moreover, the new shape of workpiece is still increasing according to the ship specification

pc based off line programming using vrml for welding Robots in shipbuilding
Robotics Automation and Mechatronics, 2004Co-Authors: Chang-sei Kim, Keum-shik Hong, Hans Yongsub Han, Sooho Kim, Soonchang KwonAbstract:In this paper, a PC-based offline programming (PC-OLP) method for welding Robots in shipbuilding is proposed. Also, this paper explains the methodology of 3D simulations for new type Robotic systems. The proposed OLP system consists of a Robot's 3D simulation, a block arrangement simulation, an optimal path planning by genetic algorithm (GA), an automatic Robot program generation, and a Tribon CAD interface. The strength of the developed OLP system lies in its flexibility in handling the changes in the Robot's target objects. Also, by use or the developed OLP, the operator can generate Robot programs very easily and quickly. We employ Visual C++, Open Inventor, Virtual Reality Modeling Language (VRML), and Windows 2000 system. The VRML makes the developed OLP possible to extend to an Internet-base OLP. The developed OLP can also be used for other Robot Applications such as painting or grinding Robots in shipbuilding industry.

Robots in the shipbuilding industry
Robotics and Computer-integrated Manufacturing, 2014Co-Authors: Donghun LeeAbstract:Abstract In this paper, details of the uses of various Robots in the shipbuilding process are provided, with an emphasis on newer developments and Applications. The current state of Robot Applications will be discussed according to the priority of the shipbuilding process. First, various Robots for open structures, such as several types of welding carriages and 6-axis articulated Robot manipulators, will be reviewed in terms of their mechanisms and Applications. Second, several attempts to design autonomous mobile Robotic systems for closed blocks of the double-hulled structure of a ship will be discussed in terms of the performance characteristics of their proposed self-traveling mechanisms. Lastly, all corresponding technologies for overcoming structural complexities in closed blocks as well as future directions of Robot automation in the shipbuilding industry are also discussed.

miro middleware for mobile Robot Applications
International Conference on Robotics and Automation, 2002Co-Authors: Hans Utz, Stefan Sablatnog, Stefan Enderle, Gerhard K KraetzschmarAbstract:Developing software for mobile Robot Applications is a tedious and error-prone task. Modern mobile Robot systems are distributed systems, and their designs exhibit large heterogeneity in terms of hardware, operating systems, communications protocols, and programming languages. Vendor-provided programming environments have not kept pace with recent developments in software technology. Also, standardized modules for certain Robot functionalities are beginning to emerge. Furthermore, the seamless integration of mobile Robot Applications into enterprise information processing systems is mostly an open problem. We suggest the construction and use of object-oriented Robot middleware to make the development of mobile Robot Applications easier and faster, and to foster portability and maintainability of Robot software. With Miro, we present such a middleware, which meets the aforementioned requirements and has been ported to three different mobile platforms with little effort. Miro also provides generic abstract services like localization or behavior engines, which can be applied on different Robot platforms with virtually no modifications.
