A plotter is a printer that interprets commands from a computer to make line drawings on paper with one or more automated pens. Unlike a regular printer, a plotter can draw continuous point$-$to$-$point lines directly from vector graphic files or commands.

Now design such a plotter to print in a $2$D space with a standard ball$-$point pen.

I. Is a stepper motor essential in this project? Explain the reason.

II$.$ Draw necessary block diagrams, pseudo$-$code and iterations of your proposed plotter.
