Learn- how to make a drawing of homework writing machine for student using arduino nano micro controller.For the X and Y axes we will use two stepper motors and rails from dvd/cd drives and for the Z axis we will use a small servo motor that moves the pen up and down.

The machine uses a gantry to move the writing tip along the X and Y axes. The flexible-nib calligraphy pen is mounted on a sprocket which rotates the tip onto the writing surface, taking care of the third axis.
You can use the machine to do pretty much whatever you can dream up from drawing fancy artwork to extensive calligraphy on letters.
Combined with personal handwriting software, you could even use the plotter to write a letter in your own handwriting without all of the effort.
