“How can we turn a screw with high-precision?”
When working with high-precision machinery, we often want to be able to turn a screw in a very controlled manner. However, doing so manually is quite a complicated task. So how can we use our engineering mindset to solve this problem? Well, let’s start with some mechatronic theory. We know that if we energize a motor, it will move rotationally. And if it does so in a belt-train system, then the entire system will move. Furthermore, if we attach a piezo on the lower chain, then it can push back in response to pressure. So what if we were to combine all of these aspects into one unified system? Well, we would then obtain a very useful engineering instrument known as a picomotor, and can be found in precision motion devices everywhere.
