Industry 4.0 - A Glimpse
The industrials
technologies are always in a fast development. It all began with the first
industrial revolution, with water and steam powered machines, to the last
revolution industry 4.0. The term Industry 4.0 stands for new organization and
control over the whole chain of the life of products. It is geared towards
increasingly individualized customer requirements.
Lots of new technologies have been developed for the integration of industry 4.0. Some of them are Big Data and Data Analytics, autonomous Robots, Internet of Things, Augmented and Virtual Reality or additive manufacturing. Also the vertical and horizontal integration of systems is strongly being pushed by industry 4.0.
To put it in a nutshell, industry 4.0 increases the effective of machines, makes products and machines smart so they communicate together, optimizes Energy consumption and much more. In the whole this means cheaper production of more individual products.

Maker's Abstract of I4.0: A review on industrail automation and robotic
This paper reviews th industrial automation and robotic used in Industry 4.0. Industry 4.0 is a fast rising topic and it is hard to stay up to date with today's technology.
This paper gives a short overview on the history of industrial revolution, technology of I4.0, robots in I4.0, international robotic organisations in I4.0, the industrial robotics potential in Malaysia and the impact of robotic I4.0
Since the advent of Information and communication technologies (ICT), economies of countries around the world increases dramatically as companies can compete on a global scale to grab the opportunity that presents. German intends to become the leading market for Industry 4.0 solutions lead the industry 4.0 revolution since 2011 to materialize its high-tech vision so that many of the company, organization and researcher take this opportunity to advance their knowledge and technology.

Galilieo Galilei - The Falling Bodies Experiment (1589)
Galilio Galilei’s famous scientific experiment was named the falling bodies experiment, because he had proved that the speed of falling objects was not related to their mass.
Between 1589 and 1592 Galileo had dropped two spheres of different
masses from the leaning tower of Pisa to demonstrate that their time of descent
was independent of their mass.
He also discovered through this experiment that the object fell with
the same acceleration, proving that his
assumption was true. At the same time he had disproving Aristotle’s theory of
gravity, where he had pretended that objects are falling at speed proportional
to their mass.
The theory of Galileo was, that lighter objects falling slower than
heavier objects due to the air resistance.
Most historians believe that this experiment was rather a thought
experminet instead of a physical test.
Experiment:
Galileo did this experiment by using two objects with sphere shape, one
cannon ball and one wooden ball. The weight of the wooden ball was the tenth of
the weight of the cannon ball. According to the theory from Aristotelian, the
cannon ball should be ten times faster, than the wooden ball. So, by the time,
when the cannon ball hit the ground, the wooden ball should only have traveled
10 percent of the distance to the ground.
Galileo dropped this two balls off the leaning Tower of Pisa in an
attemt to disprove Aristotle's theory and proving his.
The results:
At first the wooden ball fell a bit faster but the cannon ball overtook
the wooden ball and was landing slightly before the wooden ball.
So, this experiment could not prove the theory of Galileo, but he took
these results and over the next decades he came up with the Law of Falling
Bodies.
This states, that in a vacuum all bodies are accelerated in the same
way, regardless of their weight, shape or specific gravity.
The Stanford-Prison-Experiment
The
Stanford-Prison-Experiment
This was a
psychological experiment about the behaviour between the prisoners and the
prison officers in a real prison. „The Stanford experiment„ was created by Professor
Philip Zimbardo. This experiment was conducted 1971 in a real prison in Stanford.
At the beginning volunteers were randomly assigned to be either a prisoner or a
prison officer. The leader of this test was the superintendent of the prison. The
beginning of the experiment was that real policemen publicly arrested the
volunteers. After arresting the volunteers went into specially set up cells in
the basement. The cells were very bad without any window. The cells had only a
small hole for some light. Through an intercom the prison officers communicated
with the prisoners.
After six
days the experiment was abandoned. The reason for that was the behaviour of the
prison officers. They enforced their rules to much and some of the prisoners
were part of psychological tortures. Some of the prisoners accepted that.
Others of them tried to stop it. Some findings of this experiment have been
called into question because of the unscientific methodology and possible
fraud.
