Welcome to the Polar Printing Press project website!
This website follows the story of our team as we built a machine that draws images.
Initial Project Proposal
We plan to create a polar printing press: machine that spirals out an arm and attached marker to draw a 2D image.
Our minimum viable product is one black marker attached to one arm. The MVP should take a black and white image as an input and draw by spiraling the marker outward from the center.
Our dream printing press will create tri-color drawings, a neat (online) GUI for uploading images to the machine, and communicate wirelessly with any computer.
Our objective was to build a machine that actuated a marker in order to draw any image fed into the system. Our current project state is a machine that uses a single marker actuated by a solenoid on a gantry that is spun by a high accuracy stepper motor. A platter under the gantry spins the paper. When the solenoid actuates it brings down the pen onto the moving paper.
An image is fed and saved to the directory on the computer and the Python script is run. Once the arduino has recived command from Python over a serial connection, the machine begins spinning and drawing. The machine is capable of converting any image to black and white and drawing it.
