5 > Basic Technologies > Introduction One of the most important and influential technologies nowadays as well as in the future regarding Industrial Automation and Mechatronics is the technology dealing solely with robotics. Therefore the following technology concept on hand covers all major fields of the technology stated above, especially in focusing on processes that can be accomplished using robotics. Most of Festo Didactic training solutions covering the so-called basic technologies is conducted on equipment packages and learning systems, providing expedient exercises by hands-on training as well as in-depth technology training. Further on, blended-learning arrangements are implemented wherever applicable to provide insights and further opportunities to simulate, demonstrate and even control robotics applications. The picture as follows, Picture K_01, shows one example of training on robotics technologies. Picture K_01: Example of an application in robotics Training Approach Based on Festo Didactics experience, training being conducted in the field of robot technology and its applications is taking place in a group of two trainees. This fosters not only the technical experience and knowledge, but also the soft-skills and communication attempt. Trainees work on so-called MPS Stations comprising Robot and Assembly together with computer systems. Therefore one trainee can make use of the real equipment whilst the other trainee is programming and simulating offline. Together with the hardware equipment, other training media are being used, such as textbooks, workbooks and software. The laboratory layout along with the equipment allows further on different kind of training. Whenever the hardware is not used, normal classroom training can be conducted by use of the computer systems. For this purpose, the set-up of the laboratory avoids a narrow view of the instructor and its displays. K-3

6 > Basic Technologies > Modular Production System The Modular Production System, in short MPS, allows industrial automation systems of different levels of complexity to be modelled, respectively training contents to be covered. MPS is universal, modular and open to further system expansion. This allows the system to be adapted to trainees prior knowledge and experience. Simple functions and sequences form the basis up to complex production systems on a small scale, but including an option of gradually being expanded to a complex integrated system. The picture further below, Picture K_02, shows an entire MPS line, although only two stations, the Robot and Assembly Station are used within the conceptualisation on hand of robotics. Whenever an extension of the laboratory is required, more MPS Stations may be added, therefore a general introduction will follow in the proceeding paragraph. However, several other laboratory within the Teciam concept will provide more MPS Stations anyway, so that the focus clearly remains on robot technology. Picture K_02: Example of a combination of MPS Stations The MPS range of products consists of different stations, providing different kind of core competencies according to the needs and requirements to be trained. Different stations can be combined according to the material flow, building up a complete small production line. The stations further on can be separated as well, allowing an approach of the core competence training of each station s major technology. Within robotics, the station of Robot and Assembly however shall remain connected at any time. Whenever MPS Stations need to be combined or being intended for separation, no additional wiring or programming is necessary. This safes extraordinary time which can be very well used for the major subject: training purposes. Further on, all MPS Stations can be controlled according to local industrial standards, fostering the employability of trainees. K-4

7 > Basic Technologies > Technology Contents The following overview and table, Table K_01, provides an overview of the MPS Station Robot and Assembly used for training purposes within the conceptualisation on hand of robot technology. As aforesaid, Festo Didactic usually provides such stations focussing each on a certain technology accordingly. Equipment MPS Station Robot MPS Station Assembly Training contents The most complex and for sure the most flexible handling device in an industrial environment is for sure a robot. Therefore this learning arrangement, consisting of a robot and an assembly station, deals solely with an application of assembling parts using a robot. Different learning strategies can be applied in the range of teaching, simulating as well as programming a robot as well as in combination with an assembly task to be fulfilled by a robotics application. Table K_01: Training contents of robot and assembly Training Aims and Core Competencies According to the equipment sets as described in the previous paragraph, the following tables, Tables K_02 and K_03, provide an overview of the training aims and core competencies which should be achieved by conducting appropriate training in robotics, assembly as well as material handling. Equipment MPS Station Robot Training aims and core competencies Fundamentals of robot technology Robot terminology Robot programming Commissioning of the entire sequence Teaching a robot using the handheld device Safety and security applications Table K_02: Training aims of MPS Robot Station Equipment MPS Station Assembly Training aims and core competencies Mechanical setup of a station Correct wiring of electrical components Correct application of limit switches Introduction and application of automated assembly Commissioning of the entire sequence Integration of the station and combination with robot station Table K_03: Training aims of MPS Assembly Station K-5

8 > Basic Technologies > Laboratory Facilities To be able to conduct sustainable training, especially whereby hands-on training cannot be neglected, it is indispensable to provide adequate training equipment and facilities for the trainer as well as for students. Laboratory design, work environment as well as equipment design is an important factor to conduct technical training. Regarding the equipment itself, Festo Didactic uses solely real industrial equipment to compose its technology packages. Training, especially hands-on training in the technical field is only efficient when an appropriate laboratory environment is provided. Thus, a comprehensive approach starts with the laboratory design itself, is further to be recognized within the stations as well as the major part, the equipment itself. Through the medium of design, students should be already motivated to discover the technical subtlety! On the one hand side, real industrial equipment facilitates the approach of bridging the gap between institutional based training and training on the job. Thus, students are being trained on equipment which they will face later on in real industrial processes. On the other hand side, real industrial components are more reliable regarding the period of operation, upgradeability and spare parts if required. Another important aspect is safety, security as well as the training of maintenance and service. Laboratory Design The laboratory for robot technology is designed to host altogether twelve students, working in groups of two trainees on three MPS Robot and Assembly Stations and six student tables as it can be seen in the virtual impression of this laboratory in the picture further below, Picture K_03. As already mentioned, one major aspect of the design is to provide the trainees an unrestrained view on the teachers desk as well as the boards. Further on, the computer systems are located close to the workstation, in order to be implemented in a blended-learning arrangement and therefore being connected to the equipment. Whenever hands-on training is taking place, both trainees can work on the stations, whilst the others use the virtual robot environment on the computer. Apart from the major equipment, accessories such as a computer network and central power supply are taken into account, but not explicitly drawn in the layout. In order to provide a nice and warm ambient of the laboratory, curtains, posters and flowers should be a decorative matter. A future option for the laboratory on hand could be the newly designed Robot Vision Cell, as the picture further below, Picture K_04, presents. Laboratory Accessories In order to provide an adequate learning arrangement, several laboratory accessories should be implemented in the training environment. As aforesaid, this is for instance a computer network, which may be realized as a client-server based architecture. This allows the trainer gaining access to the students computers and the possibility to check which kind of exercises they have performed successfully. Further on, the network allows the students to print on the laboratory printer. Last but not least, whenever a Web Based Media Library is being implemented, then trainees shall also obtain access to the intranet of the institution. Further accessories, such as a printer, a projector, storage shelves as well as whiteboards and chairs are obvious. K-6

The sensor in the gripper enables the robot to differentiate workpieces by colour (black/not black). The sensor in the assembly retainer monitors the orientation of the workpiece. From the assembly retainer the robot sorts the workpieces into various magazines or passes them on to the downstream station. Combination with the assembly station facilitates the assembly of workpieces. Small, but great: The new Mitsubishi controller. The new drive unit for the RV-2SDB is small, powerful and lightweight, and fits into the MPS trolley. With drive unit and Teachbox, the robot station is completely equipped right from the outset. The gripper can grip and assemble different types of workpieces (cylinder bodies, pistons, springs and caps). K-8

11 > Basic Technologies > Assembly Station The MPS Assembly Station comprises of the components as shown and listed below. Each item and quantity refers to one single station. Some components and accessories are however omitted willingly. 1 1x MPS Station Assembly, completely assembled including trolley 2 1x Separating module for springs 3 1x Piston pallet module 4 1x Stack magazin module for end caps 5 1x Syslink connection terminal 6 1x Valve terminal 7 1x On-off valve with air filtration 8 1x Profile plate 9 1x Set of tubings and fittings 10 1x Set of cables, accessories and tools Function of Assembly Station The Assembly station works in conjunction with the robot station. It supplies cylinder components for the assembly process: A double-acting cylinder pushes the cylinder caps out of the stacking magazine. The pistons are stored on a pallet. A double-acting cylinder pushes the springs out of a slim magazine. Multiple parts for complex assembly. The Assembly station shows just how complex the workpiece used here is. There are separate magazines for bodies, caps and springs; the quantities available have to be monitored by carefully selected sensors. And in addition to this, it has to be decided which gripper type is required for the assembly robot. K-9

12 Station Verteilen Ausbildungsunterlage DE 11/03 Teciam > Basic Technologies > Accessories for To provide a complete viable system, several important accessories are strongly recommended, therefore the following table lists further details. Some minor accessories will not be shown, such as cables, connectors or power supply cables. In case no central compressed air is available then also compressors will need to be added. 1 1x Power supply unit 2 1x Set of workpieces 3 1x Programming instructions for Robot 4 1x Technical manual for Robot 5 1x Control console 6 1x Set of tools Teaching Media What is the best training equipment for teaching purposes without appropriate teaching material? To provide an answer to this question, Festo Didactic offers a wide range of teaching media to put a holistic concept of technical training on firm footing. Training, especially technical training including a hands-on approach is only efficient with the right blend of media! Therefore three major aspects need to be considered: real industrial equipment for teaching purposes, appropriate software along with the blended-learning approach and finally teachware in forms of textbooks, exercises, data sheets and workbooks. In the following paragraphs, the teaching media part is split into the section of teachware, whereby textbooks and workbooks will be mentioned. Further on, one section will provide an overview about the software media which supports the teacher as well as the trainee according to the equipment details as described. Textbooks and Workbooks The following table, Table K_04, presents all textbooks, workbooks and exercise media according to the technology packages in the field of PLC, AS-Interface, Profibus-DP, Sensors and others.

13 > Basic Technologies > Software Following our approach of providing expedient training concepts, the following paragraphs provide all information regarding the range of software based media in the field of electropneumatics, logic controllers, fieldbus technology and various others. In the first case, trainees can gather some preliminary experience in the field of electropneumatics or fieldbus technology by using so-called Web Based Media, which could be accessible via the intranet, but also as a local installation. Once students have acquired some background information about various technologies, hands-on exercises on the real industrial equipment should corroborate this knowledge. Afterwards simulation and measuring software tools in combination with the hardware allows the trainee to foster its skills and knowledge in the corresponding technical field. This educational approach follows our ideas of establishing a blended-learning arrangement. The following paragraphs provide all necessary information about software tools to understand the right way of its designated usage. Sensor Technology 1 The first part of sensor technology focuses on sensors in pneumatics for about two hours of learning time. This training program deals in detail with the sensors used to detect end position on cylinders and with pressure and flow sensors in pneumatic systems. Based on a complex example from industrial practice, trainees are taught to select suitable sensors. The necessary basic knowledge for this is provided in the technical knowledge and components modules, to which trainees can refer at any time. All training content is taught by means of audio clips. Additionally, the narrative text can be viewed on the sitemap. The picture as follows, Picture K_05, provides an idea its appearance. Picture K_05: WBT Sensor Technology 1 and 2 Sensor Technology 2 The second part of sensor technology focuses on sensors for object detection for about two hours of learning time. This training program deals in detail with the sensors used to detect objects in automated systems. Based on a complex example from industrial practice, trainees are taught to select the suitable sensors. The necessary basic knowledge for this is provided in the technical knowledge and components modules, to which students can refer at any time. All training content is taught by means of audio clips. Additionally, the narrative text can be viewed on the sitemap. The picture above, Picture K_05, provides an idea of its design. K-11

14 > Basic Technologies > CIROS CIROS is ideally suited for learning how to program and commission industrial robot systems. The program offers a large number of different robot models. The integrated training program on robotics conveys everything from the basic principles of handling technology to the use of robots in space missions. All the required basic knowledge for automation with robots is conveyed by the integrated CIROS Assistant which offers numerous graphics and animations to explain technical terms and facts, videos on a large number of industrial applications involving industrial robots, sample programs for every robot work cell, technical documentation including instructions on processing. The picture as follows, Picture K_06, provides an idea of its design and appearance. Picture K_06: CIROS CIROS includes as well a 3D real-time simulation with all the features of CIROS Studio. Additionally, a programming environment for IRL (Industrial Robot Language), programming languages Movemaster Command and Melfa Basic IV for the class of Mitsubishi robot systems. Further to this, a comprehensive library with more than twenty predefined robot work cells enables trainees to go directly to commissioning and programming of robot applications: from simple pick and place tasks right up to plants with numerous robot systems.

15 > Basic Technologies > Mechatronics Assistant The Mechatronics Assistant, designed to cover all training aspects for MPS in particular, is a tool for every purpose. The time previously lost researching, copying, collating, stapling and distributing is a thing of the past. The new Mechatronics Assistant is a syllabus-oriented, structured archive as a software application in which instructors and trainees can easily find the documentation for the classes, at any time. Altogether more than various documents are comprising the Mechatronic Assistant, ranging from exercises, data sheets, assembly instructions up to wiring and functioning diagrams. The picture as follows, Picture K_07, provides an idea of its design and appearance. Picture K_07: Mechatronics Assistant Installation and Training One important aspect before conducting training using the robot and assembly environment as well as the various software tools is to provide the right installation of the equipment, infrastructure, accessories, tools and the corresponding facilities. This will be accomplished by Festo Didactic experts within the field of robotics, having a profound experience and being able to meet any local requirements. In case further laboratories will be established having the same set of equipment and software tools, then training can however take place in parallel and together. Training, especially training in the technical field, is only efficient when all trainers involved are extensively trained in their designated field and training approach. Only well trained and motivated trainers are able to motivate students thereafter, therefore any kind of the so-called train-the-trainer aspect should not be neglected. Upon necessity, revision training should be considered on a frequent basis. In case the laboratory conceptualisation on hand will be established as a stand-alone laboratory solution, a training duration of at least five to eight days is recommended. As aforesaid, in case the laboratory of robotics is part of various laboratory installations, then this time could possible be covered in related laboratories respectively other technologies. Further Information As already mentioned, since Festo Didactic is constantly further developing and adding new equipment and software media to its existing wide range, further and latest information can always be accessed using the website of Festo Didactic, This also includes further information regarding installation requirements.
