The information looks good as well as the layout. Good use of citations among page. Maybe at the beginning add a section that lists the different types of machines.

I like your information and how many numbers and facts that you have brought to the article.

Minor correction: once or twice throughout the article you state facts without an immediate citation. I assume that you have found these facts, and it would be more organized if you put citations after all of them or at the end of the paragraph as you did for [7]. Other than that keep up the good work.
