Purpose: of this paper is to present agent-based and object-oriented approaches in the desingning of robotic work cells. The complexity of elements which form the robotic work cells causes that already at the design stage it is necessary to evolve the models that comply with different aspects of the conformation and principles of the operation of the workcell. Design/methodology/approach: The use of agent-based and object-oriented approaches during the process of robotized workcell's design, allows i.a. to systematize the knowledge about the designed workcell and simplifies the definition and analysis of relationship between its components. Most modern systems CAD/CAM uses object-oriented structure. They do not allow the creation of a direct structure agents. It is therefore necessary to show the relationship between the object and the agent. Findings: The relationship between object-oriented and agent-based model allow to fill the gap between them. Understanding of them could allow more efficient use of existing systems that are decicated for designing of robotic work cells. Research limitations/implications: The presented considerations are only the introduction to the further work on developing these methods for the use during the design process of robotic cell, and clearly do not cover all the issues involved, hence there are also other open issues for future research that could generalize the researches or could be a starting point for a new ones. These problems may concern e.g.: development of appropriate methods of communication and cooperation between the agents or the definition of the new agents that can act autonomously according to their own algorithms. Practical implications: The main objective is to build the base for modular and flexible system that will allow designing of robotic work cells using the methods presented in the paper. Due to high cost of such systems, there is no reason to make it from scratch. The better way is to integrate the existing applications and use the synergetic effect of such approach.

Purpose: The aim of this work was to design and build a laboratory stand dedicated for didactic and research purposes connected with a Fluidic Muscle. The stand is placed at the Electropneumatic and PLC controllers Laboratory [10,11,12] of the Institute of Engineering Processes Automation and Integrated Manufacturing Systems of the Faculty of Mechanical Engineering of the Silesian University of Technology, Gliwice, Poland. Design/methodology/approach: The stand was designed and visualised by utilisation of professional CAD software - CATIA and a fluidic muscle was chosen according to a MuscleSIM programme of FESTO company. Findings: The device integrates the elements which are indispensable determinant of contemporary industry and the main aim of its construction was to bring closer conceptions and ideas connected with the construction and the outworking of the fluidic muscle, problems of proportional pressure control, visualisation and control of the industrial processes as well as making possible of carrying out the investigations and experiments on these elements. Research limitations/implications: The module structure of the research stand gives possibility to make its further development by adding extra modules that can be easily mounted on plates, which will make possible the implementation of series of individual positions controlled by one PLC. Thanks to the applied system of visualisation, switching among synoptic screens is possible. The visualisation represents every separate module of the stand and so, with the help of one operator position, gives possibility to control every chosen module of the whole device. Originality/value: The mechatronic didactic and research device introduced in the paper represents the new approach to the problem of visualisation and control of the fluidic muscle and constitutes the perfect tool of the aided didactic process in the Institute's laboratory.

Purpose: The aim of this paper is to show the laboratory equipment, the methods of learning and the results of education process in student’s preparation for realization of industrial tasks. Design/methodology/approach: The paper presents the models elaborated by students as results of semestral or BSc Eng. works. Findings: Contemporary higher education must be directed to educate students according to needs of employers. In order to be up to these needs, a new technology should be presented and used during realization of syllabus. Moreover, the students should solve the real problems from industry. Practical implications: Working on real industrial problems and developing models introduce a new trend in practical teaching. Student involved in the project gets skills in engineering by completing the tasks from an idea to a working model. Originality/value: All of the projects presented in the paper have been made by the students according to their original concepts. In the Institute of Engineering Processes Automation and Integrated Manufacturing Systems the emphasis is put on these tasks, which are realized within the confines of diploma thesis, semestral works or researches with employees of the Institute.

Purpose: Modern companies tend towards the greatest possible automation in all areas. The new control concepts of manufacturing processes required development of adequate tools for the introduction of automated control in a certain area. The paper presents such system for automated programming of CNC machine tools. Design/methodology/approach: The system is based on the previously incorporated know-how and the rules of it implementation in tool – shop. The existing manufacturing knowledge of industry tool production was collected and analysing. On this bases flow chart of all activities were made. Theoretical contribution is made in systemization of technological knowledge, which is now accessible for all workers in NC preparation units. Findings: Utilization of technology knowledge. On the basis of the recognized properties it has worked out the algorithms with which the process of manufacture, the tool and the optimum parameters selected are indirectly determined, whereas the target function was working out of the NC programme. We can first out that with information approaching of the CAM and CAPP the barriers between them, strict so far, disappear. Research limitations/implications: Till now, the system is limited to milling, drilling and similar operation. It could be extended to other machining operations (turning, grinding, wire cutting, etc.) with the same procedure. In advanced, some methods of artificial intelligence could be use. Practical implications: It is suitable for industry tools, dies and moulds production, while the system was proved in the real tool shop (production of tools for casting). The system reduces the preparation time of NC programs and could be used with any commercial available CAD/CAM/NC programming systems. Human errors are avoid or at lover level. It is important for engineers in CAD/CAM field and in tool – shops. Originality/value: The developed system is original and was not found in the literature or in the praxis. Developed method for preparation of NC programs is new and incorporate higher level of automation.
