    Robotic de-palletizing system for the non-flat ceramic industry (2003)
    Bradford : Emerald
    Industrial robot 30 (2003), S. 152-158 
    Details
    ISSN: 0143-991X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The paper describes a prototype developed to de-palletize non-flat ceramic pieces in the final stage of production, just after they leave the high temperature oven, feeding the final human operated inspection lines. The prototype is installed at ROCA, a Spanish company operating in Portugal, and works with all their models of toilets and bidets. Special attention is given to human machine interfaces (HMI) and safety. The emphasis is on components and on integration with the environment chosen for operation rather than the specifics of operating system selection.

    CAD interface for automatic robot welding programming (2004)
    Bradford : Emerald
    Industrial robot 31 (2004), S. 71-76

    Notes: Industrial robots play an important role in industry, due to their flexibility. Many applications (almost all that require human intervention) may be performed with advantages by robots. Nevertheless, set-up operations, necessary when changing production models, are still tricky and time-consuming. It is common to have detailed data of working pieces in computer aided design (CAD) files, resulting from product design and project. This information is not used satisfactorily, or even not used at all, for robot programming. In this paper, we propose a solution capable of extracting robot motion information from the CAD data.

    Notes: Purpose - This technical paper reports the development of an industrial robotic labeling system, designed to insert identification labels on rolls of paper coming from an industrial paper machine. Design/methodology/approach - The system was developed for an existing installation comprising a paper machine, a roll measuring and weighting station and a roll wrapping machine. The labels identify each roll by means of barcodes, which are used internally in the factory to identify and store each roll at the automatic warehouse and by the customer company for similar purposes. Findings - In describing an industrial application designed for labeling applications, this paper discusses and details a software interface designed to command shop-floor manufacturing systems remotely from the manufacturing tracking software. This adds in terms of flexibility and agility, since all available operations were implemented in a very general way requiring only simple parameterization to specify the individual operations. Practical implications - Since the TCP/IP server is a general implementation, using the BSD compatible TCP/IP socket implementation from Microsoft, it can receive commands from virtually any client. This makes this robotic cell interface an interesting way to command shop-floor manufacturing systems. Originality/value - Demonstrates a method for controlling shop-floor manufacturing systems that has broad applications.

    Object oriented and distributed software applied to industrial robotic welding (2002)
    Bradford : Emerald
    Industrial robot 29 (2002), S. 149-161 
    Details
    ISSN: 0143-991X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Associating robot manipulators with industrial welding operations is common and maybe one of the most successful applications of industrial robots. Nevertheless, it is far from being a solved technological process, mainly because the welding process is not fully understood but also because robots are still at an early satge of development, being difficult to use and program by regular operators. This is also true for Human Machine Interfaces (HMI), which are not intuitive to use and are therefore unsatisfactory. In this paper we discuss these problems and present a system designed with the double objective of serving our R&D efforts on welding applications, but also our need to assist industrial partners working with welding setups. Frequently industrial partners are not happy with available commercial systems, requiring tailored solutions that could be adapted to several robots and robot controllers. The developed system is explained in some detail, and demonstrated using two test cases which reproduce two situations very common in industry: multi-layer butt welding (used on big structures requiring very strong welds) and multi-point fillet welding (used for example on structural pieces for the construction industry).

    Industrial robotic system programmed from CAD files - an update (2005)
    Bradford : Emerald
    Industrial robot 32 (2005), S. 314-317 
    Details
    ISSN: 0143-991X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Purpose - In this paper a solution capable of extracting robot motion information from CAD data is briefly presented and explored. Design/methodology/approach - The motion information is added by the user to the CAD file, defining in this way the approach, fly-by and welding trajectories. So the user programs the robot. An application is then used to extract that information and constitute a pre-program, which should be tuned with the real robot using a small set of rules. In this way, versatility of robotic cells is improved and its programming is simplified. Findings - The developed CAD interface is tested using a robot welding experiment on a steel beam used for industrial buildings. Originality/value - This paper builds on work previously described in "CAD interface for automatic robot welding programming" published in Industrial Robot, Vol. 31, No. 1.

    Notes: This paper addresses some aspects related to Flexible Manufacturing Cell (FMC) programming, and is based on two previously published papers and focuses more on application details. Recognising that one of the major problems of today's Flexible Manufacturing Cells is the diversity of languages and hardware architectures present in the same FMC, we introduce an object-oriented and distributed software architecture that can be used for FMC programming and monitoring. Application examples of an industrial FMC and an R&D/education setup are presented, in which we used an industrial robot and a force/torque/acceleration sensor. In the process some implementation details are presented and discussed.

    Robot-by-voice: experiments on commanding an industrial robot using the human voice (2005)
    Bradford : Emerald
    Industrial robot 32 (2005), S. 505-511 
    Details
    ISSN: 0143-991X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Purpose - This paper reports a few results of an ongoing research project that aims to explore ways to command an industrial robot using the human voice. This feature can be interesting with several industrial, laboratory and clean-room applications, where a close cooperation between robots and humans is desirable. Design/methodology/approach - A demonstration is presented using two industrial robots and a personal computer (PC) equipped with a sound board and a headset microphone. The demonstration was coded using the Microsoft Visual Basic and C#.NET 2003 and associated with two simple robot applications: one capable of picking-and-placing objects and going to predefined positions, and the other capable of performing a simple linear weld on a work-piece. The speech recognition grammar is specified using the grammar builder from the Microsoft Speech SDK 5.1. The paper also introduces the concepts of text-to-speech translation and voice recognition, and shows how these features can be used with applications built using the Microsoft.NET framework. Findings - Two simple examples designed to operate with a state-of-the-art industrial robot manipulator are then built to demonstrate the applicability to laboratory and industrial applications. The paper is very detailed in showing implementation aspects enabling the reader to explore immediately from the presented concepts and tools. Namely, the connection between the PC and the robot is explained in detail since it was built using a RPC socket mechanism completely developed from the scratch. Practical implications - Finally, the paper discusses application to industrial cases where close cooperation between humans and robots is necessary. Originality/value - The presented code and examples, along with the fairly interesting and reliable results, indicate clearly that the technology is suitable for industrial utilization.

    Handling production changes online: example using a robotic palletizing system for the automobile glass industry (2004)
    Bradford : Emerald
    Assembly automation 24 (2004), S. 254-263

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: In this industrial case study paper the problem of handling production variations online, i.e. during actual production, is addressed. These variations may occur when it is not possible to exactly guarantee working conditions during a production cycle or between two consecutive cycles. These variations are common in some types of industries, like the glass and ceramic industry, where the products may change slightly during the production cycle. Since it is common to have two or more different model campaigns during a working day, it should be possible to easily parameterize the production system when a new campaign is started. This paper uses a highly-efficient robotic palletizing system, developed for the partner company Sekurit Saint Gobain (Portugal), to introduce and explain how these problems may be addressed. The paper includes details about practical implementation, along with discussion of options and obtained operational results, showing it to be a good example of human-machine co-operation.
