Define axis and angles
Simplify the robot model
The 3D model of the Lego robot is quite complex and is therefore not suitable for determining the axes.
To make it easier to measure the robot model, the complex Lego model was simplified. The center distances were taken from the complex model.

In order to be able to test all functions, a demo program is stored with which all axes are operated. The axes are approached up to the maximum limits. Here it turned out that the maximum deflection was not recognized for axis 5. After checking the cables and the signals, the error is then only a magnet that has fallen off during transport. This is detected by the magnetic sensor TLE5012B and thus the end stop can be determined. After the correct attachment, the robot functioned properly again and the demo run could be completed.
Start the robot project
The 6-axis robot was built by Dr. Olaf Filies together with his son Marcus, to be seen in the YouTube video ( https://www.youtube.com/watch?v=K0sfWzCfdn8&t= 70s). For the control, the controller XMC1100 and 2 motor shields TLE94112 were used. To measure the rotation of the axes 6 magnetic sensors TLE5012B are used which are connected to the controller via SPI. The programming of the robot was done with the Arduino
user interface. This project was then ported to the XMC4700.

Thing 23: Digital Competence Assessment
There are many things I already knew, but there is also a lot of new things to learn or things I already knew but from a different perspective. This course was very interesting and I am glad I took it. It takes much more time than previously estimated, but this time was not in vain. I tried to start a blog a long time ago and tried again last year. But the result was never more than a few lines. Here in this course I decided to reactivate my website and I want to be much more active on my blog in the future. That is the most positive result in this course. There are also many very interesting topics in this course, such as how I can get digital content and use it without violating digital rights.
The most complex part for me was item 19 „Virtual and Augmented Reality“. I found, tested and watched so much content that it takes several days to write about this topic.
Below you can see the test I made with the Digital Skill accelerator.
