In this paper a new teaching-learning-method including
the LEGO Mindstorms EV3 is presented. This computer
sciences course is part of the studies of mechatronics in the first
two semesters. The programming language being mediated is
ANSI-C. Computer science is not the most popular subject in
the interdisciplinary engineering field of mechatronics, therefore
the EV3 should be included to increase motivation. For the new
approach the former course – without the usage of EV3s – was
evaluated and a competency profile was identified. On this basis
a new didactical method was designed and implemented.
The EV3 is programmed with the IDE Eclipse and with a self
programmed plug-in.

Within the project SLOBATCO (Slovak-Bavarian Telescope Collaboration)
the Astronomical Institute of the Slovak Academy of Sciences and Aschaffenburg University of Applied Sciences collaborate in the development
and commissioning of scientific instrumentation for the new Ø1.3 m astronomical
telescope at the Skalnaté Pleso observatory. The joint project is funded by
the Bavarian Academic Center for Central, Eastern and Southeastern Europe
(BAYHOST). Planned technical work packages are targeting the filter wheel
software for the VIS camera, additional IR filters, and an upgrade of the mirror
coating facility by additional sputtering equipment.
Within the project SLOBATCO the question did arise, to what extend observatories have to rely on adequate
power quality, e.g. the perfect sinusoidal shape of supply voltage and current, in order to ensure safe
operation and accurate measurement results. International power quality standards are put in perspective
with requirement specifications. Telescope operators indicate partial or total loss of function of measurement instruments. Measurements
conducted during SLOBATCO project substantiate the need for power quality measurement campaigns.

The electric power supply of astronomical observatories has to manage a conflict of
interest: Observatories are situated at remote locations, they have a high consumption
of electric power while measuring electric signals as sensitively as possible.
Within the project SLOBATCO, the question did arise, to what extent observatories
have to rely on adequate power quality, for example, the perfectly sinusoidal shape
of supply voltage and current, to ensure safe operation and accurate measurement
results. International power quality standards are put in perspective with requirement
specifications for observatories. This contribution describes themotivation, the
underlying mechanisms that lead to issues, comments on the challenge in power systems
engineering, proposes the instrumentation and installation, and interprets the
first results. Experimental results clearly motivate the need for further measurement
campaigns, as power-quality-related problems are common. A summary is provided
together with an outlook and a motivation for future measurement campaigns.
