Bootstraping is what you are looking for. A lathe is often the start of bootstraping because a lathe can make itself. You can also use a lathe to make a lathe, but if you do it that way you slowly lose accuracy over generations (but it is much faster and so most lathes are made with lathes). By having a lathe make itself you restore accuracy (and if you have learned something can sometimes get even higher accuracy than previous rounds). Before you can make a lathe you need precision flat surfaces, but it turns out only basic tools are needed to bootstrap that (and a lot of time). A lathe is considered a machine.
The point is that robots can make themselves if you program them for that. I’m making a clear distinction between reproduce themselves and make themselves here. A nearly worn out robot can restart the whole thing (so long as it does fail completely too soon) of making a new robot that is bigger and more accurate than it ever was (if bigger and more accurate is desired by the programming). That doesn’t mean the same robot could reproduce itself, instead it has to cause a robot to make itself.
Samsung appliances have had a bad reputation for more than a decade now. I don’t know how they can still sell appliances - how is it not everyone knows yet? How is it they still haven’t fixed the quality problems?
