The basic idea of the v-plotter is that lines can be drawn as needed with only 2 motors and a pen attached to a cable connected to the motors. As each motor moves the pen travels the arc around the other motor. By interleaving movements of both motors any graph can be drawn. For this project I used a Raspberry Pi, 2 stepper motors, and 2 stepper motor drivers. The code is written in Python and runs on the Pi.
