71 71 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.

73 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 * , *m Tmot = m*(r2*960+0, ) m = Tmot / r2*960+0, m = 28,4 / 0,000025*960+0, m = 232,58kg N=5 Tmot = ( m*r2 / 25 * 960+ (0, *m / 5) m = 1379,89kg Comment: I am not totally sure if this is correct. Mass is somehow big in both cases. Isn‘t that a really small motor? 73

74 74 Remote experiments with SCARA mechanism Mechatronic devices

75 75 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.

76 Outline 76 Introduction Motivation and background E-PRAGMATIC network Needs analysis Integral concept for distance education in industry Distance training modules from robotics Evaluation of integral concept, pilot training Conclusions

77 Evaluation of integral model, pilot training 77 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.

78 Evaluation of integral model, pilot training 78 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’ feedback about their perception, encountered problems, and used approaches.

79 Evaluation of integral model, pilot training 79 General profile

80 Evaluation of integral model, pilot training 80 Finished modules (survey participants only) How many E-PRAGMATIC learning modules have you successfully finished? Answer Response Percent Response Count None 26,9% ,1% ,8% ,2%11 answered question108 skipped question4 Bachelor or post- secondary voc. degree

81 Evaluation of integral model, pilot training 81 Reasons for not finishing Bachelor or post- secondary voc. degree Secondary degree, production

82 Evaluation of integral model, pilot training 82 R ESULTS OF F INAL E VALUATION, Survey’s statements and average score (0–I don’t agree, 1– neutral, 2–I agree) I appreciate time and location independency of distance training.1.8 Learning portal (LMS) and materials are well organised.1.8 The motivation questions help me to better understand the modules.1.7 Remote and virtual experiments greatly contribute to the understanding of studied modules. 1.7 Provided learning modules fulfil my education needs.1.7 I would like to participate in such training in the future.1.9 I would also pay a small fee for such distance training.1.0 My overall learning experience was excellent.1.8

83 Evaluation of integral model, pilot training 83 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.

84 Evaluation of integral model, pilot training 84 Concept was evaluated as suitable. Some important issues. Non-responding participants. A lot of passive online viewing without feedback. Lack of participation in the forum and community. Lack of time. Deadlines not always respected. Learning at own pace. Learning materials in other form. At request. Critical role of mentor. Timely answering necessary. Language obstacles. Translation of vocational level modules necessary. Remote experiments very important. Blended approach more motivating.

85 Outline 85 Introduction Motivation and background E-PRAGMATIC network Needs analysis Integral model for distance education in industry Distance training modules from robotics Evaluation of integral model, pilot training Conclusions

86 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
