I would like to get an idea how to control DC motor precisely. (i.e. deliver an object in a 100% right position) and I am not writing for the mathematical equations)
I am planning to make printer head which rotates left-right using DC motor but when I designed it, the following issue arose in my head:
I have thought that
- after the calculation and moving head using DC motor, can I 100% guarantee the accuracy of the distance?
- (from 1) if it is not accurate, it would need side components to verify its distance. How things like printer verify the distance?
I tried to search relevant information to analyze the issue, but could not find much about it.
