Pen Plotter is a CNC robot that is powered by an Arduino and runs off of Gcode. 20x20 aluminum and laser cut acrylic parts were put together with screws and had motors attached to them that were controlled by a motor driver Arduino shield. Gcode drawings were loaded onto a program called “Universal Gcode Platform” that communicated with the Pen Plotter and drew using an Expo marker. Created for Chris Whitmire's Spring 2022 CRT320 - Computer Numerical Controls class.
