The steel coils are there to make body panels with. They’re vehicle-specific, so there’s a special type of coil for the bonnet of the X2, for instance. But within a single coil, things like the thickness of the metal can still vary, which can impact the quality of the finished product. What’s new with this system is that each coil is precisely measured. As it’s unrolled, we measure the thickness of the metal, the amount of oil on it, its mechanical properties and so on. This information is useful later on in the process, so we need to be able to trace it back to the right blank. That’s why we laser an ID-code into each one. The idea is to use the parameters we record from this coil system and the laser ID code on the part to adjust the press. That way, we can produce the most perfect product possible. Another important factor is that we can use our data to recognise anything usual well in advance. That way, we can minimise downtimes in production. BMW Group Plant Regensburg was a pioneer in this regard. We developed the technology here with our colleagues from HQ and are now rolling it out at other BMW Group sites as well.

Our colleagues were already working with robots years ago. But today it’s all much more ergonomic. You can move a part that weighs 150kg with just two fingers and manoeuvre it into place very precisely – as you can see here, where the converter is being bolted into place. There used to be actual physical protective fences to keep associates away from the robots and make sure the machines don’t detect an interference and stop working. Nowadays the fences are virtual fences and use sensors to keep our associates are 100% safe. As soon as they enter the protected area around the robot, it switches off automatically so that the worker isn’t injured.
Wolfgang Weber Product and Process Planner, BMW Group Plant Regensburg.
When humans and machines work together here, human sensitivity meets the power of the robot. Humans won’t replace robots – or the other way around. Far more, the two will work hand in hand. A load of 150kg is too much for a human, but a robot can handle it. Moving into the future, there’s still plenty of potential for developing this idea. You could say that a robot with this kind of safety concept is really a high-precision handling machine. It can repeat every move perfectly and do every stage of the work. There’s still plenty of potential here.
