  5. Outline Introduction Motivation and background E-PRAGMATIC network - goals, methods, tools Needs analysis Integral concept for distance education in industry Distance trainingmodules from robotics Evaluationof integral concept, pilot training Conclusions
  6. Motivation and background EU lifelong learning program: nearly €7 billion in 2007– 2013. Distance learning at UNIs supported. USA: enterprises provide annually 32 learning hours to each employee. 25 % students take distance courses. Distance learning in engineering education is not following the trend.

  19. Needs Analysis Why needs analysis? Statistical data (EUROSTAT) and different studies provide general information about the current state of lifelong learning education. No comprehensive analyses are available, which would reveal concrete needs for continuous education in electro-mechanical sector.
  20. Needs Analysis All reports are available at the E-PRAGMATICweb page. Methodology: E-surveys for the employees and the companies‘ management. Direct interviews with the network‘s industrial partners. Results: 355 answers from whole EU. Country related reports (Austria, Nederland, Germany, Poland, Slovenia, Spain, Switzerland). General report.
  21. Needs Analysis Level of education of the responders
  22. Needs Analysis Number of years in the current professional carrier
  23. Needs Analysis Activity and profile of the company
  24. Needs Analysis Master or PhD degree Employeed in production In-company training: 77% have already participated. Reasons for non-participation:
  25. Needs Analysis Post-secondary education. Employeed in production Sources of continuing education
  26. Needs Analysis Secondary education, younger than 40 Bachelor or post-secondary voc. degree Higher than secondary edu. Production, over 40 Reasons for participation in the continuing education
  27. Needs Analysis Involvement in the distance training 32% have already participated in the distance training. 76 % believe that the distance training can be efficient also in engineering. Training time Average time available for the distance training is 6.5 hours per week (secondary education 4 hours, higher education 8hours).
  28. Needs Analysis 5 most interesting courses Emerging/alternative technologies PC-based measurement and instrument control Robot programming Electric circuits Applied control theory
  29. Needs Analysis Most interesting courses with respect to the education background of responders
  30. Needs Analysis Additional comments provided by the responders: The theoretical materials should be supported by the practical examples. Problems from practice are interesting. Usage and maintenance of new devices and new methodologies. The courses should come from the problem to the theory and not from a lot of theory to new problems!

  70. Mechatronic devices Theoretical exercise: Design of joint drive system Applied motor is DC ESCAP motor 219P (12 V) and its data are provided on the bottom of this learning unit. Load is a point mass m on distance L from the rotation axis. The mass of the stick which ends with load with mass m is negligent. For the system without the gear (N=1), calculate the maximum load mass m that can be attached at the length L=0.01 m so that the load’s angular acceleration can reach 1/50 of the maximum motor acceleration. For the system with gear (N=5), calculate the maximum load mass m that can be attached at the length L=0.01 m so that the load’s angular acceleration can reach 1/50 of the maximum motor acceleration.
  71. Mechatronic devices
  72. Comment: I am not totally sure if this is correct. Mass is somehow big in both cases. Isn‘t that a really small motor? N=1 Tmot = m*r2 * amot + L*m*ag*sinθ (Jmot is very small, so I won‘t include it) Tmot = m*r2 * amot/50 + L*m*ag*sinθ Tmot = m*r2 * 960 + 0,09810665*m Tmot = m*(r2*960+0,09810665) m = Tmot / r2*960+0,09810665 m = 28,4 / 0,000025*960+0,09810665 m = 232,58kg N=5 Tmot = ( m*r2 / 25 * 960+ (0,09810665*m / 5) m = 1379,89kg
  73. Mechatronic devices Remote experiments with SCARA mechanism
  74. Introduction to industrial robotics I have some problems. My old but good computer WIN89XP doesn‘t like LabVIEW and WebCam, but my son‘s computer with Vista works normally with both – I already did some experiments. My business laptop with cable UTP connection and home laptop with Win7 shows only static picture on WebCam. I think experiment works, but I am not totally sure. So I am sending this picture, it looks something like this. I will send exercise as soon as I solve this.
  75. Outline Introduction Motivation and background E-PRAGMATIC network Needs analysis Integral concept for distance education in industry Distance trainingmodules from robotics Evaluationof integral concept, pilot training Conclusions
  76. Evaluation of integral model, pilot training Pilot training April-June 2012 with about 200 participants. Most of the pilot training participants have participated in the needs analysis as well. Participation on volunteer basis to eliminate ‘force factor’. The participants could choose one of the suggested thematic training programs or put together their own training program.
  77. Evaluation of integral model, pilot training Evaluation on two levels (training on general, separate modules,) and from two perspectives (learners, mentors). Final e-survey. Feedback received from 114 participants. Short e-survey for each separate module. To evaluate quality of separate modules. Mentors’ feedbackabout their perception, encountered problems, and used approaches.
  78. Evaluation of integral model, pilot training General profile
  79. Evaluation of integral model, pilot training Bachelor or post-secondary voc. degree Finished modules (survey participants only)
  80. Evaluation of integral model, pilot training Bachelor or post-secondary voc. degree Secondary degree, production Reasons for not finishing
  81. Evaluation of integral model, pilot training
  82. Evaluation of integral model, pilot training Other comments Missing topics: basics of mechanical engineering, electrical grid, computer-aided design, wind energy, vehicle technology, physics, mathematics, existing topics on a higher difficulty level and translated to national languages. Training should be during winter. Only limited number of courses should run in parallel.
  83. Evaluation of integral model, pilot training Learning materials in other form. At request. Non-responding participants. Alot of passive online viewingwithout feedback. Lack of participation in the forum and community. Lack of time. Language obstacles. Translation of vocational level modules necessary. Remote experiments very important. Critical role of mentor. Timely answering necessary. Blended approach more motivating. Deadlines not always respected. Learning at own pace. Concept was evaluated as suitable. Some important issues.
  84. Outline Introduction Motivation and background E-PRAGMATIC network Needs analysis Integral model for distance education in industry Distance trainingmodules from robotics Evaluationof integral model, pilot training Conclusions
  85. CONCLUSIONS Academia-industry partnership to improve the industrial education and cooperation. E-learning as modern approach for industrial education was proven to be successful. Enterprises as end users not individuals. Exploitation program under development. Possibility for Transfer of innovation within EU Lifelong learning program. New country for application and new partners for consortium. Application deadline: February 2013.
