This one is kind of funny. It was recorded on an iPhone 6S propped up on top of a section 4×4 wood without any consideration that it would ever be edited together. So the video is an exercise in making the most out of limited footage.
I actually programmed the PLC and HMI in this system too. The routing system utilizes Siemens Function blocks heavily. There is also an HMI that is not pictured in the video.
