For the final project of my Physical Computing class, I was interested in using digital technology as a tool for making. I started with the intention of making a free-roaming/wireless drawing robot. While doing so I realised that I can get rather precise results with the stepper motors I had. I decided to look into pen plotters, which works with essentially the same logic of a 3D printer but with less sophisticated Z-axis movement.
Upon some research in both the open source community and in the commercial sector, I realized that I was making something new. All pen plotters have limited work areas because of how they work: they all move within a specifically-defined space in order to get precision. I decided to make one that is wireless and free-roaming.
