As part of a 3-month capstone design project, I worked with a team to develop a vector graphics plotter. Plotters were common for large-scale drafting through the 1980s, and there is also a thriving community of artists (#plottertwitter) who use them for creative purposes . We wanted to design a system that integrated the affordances of the plotter with modern mobile devices and image processing techniques.
The system comprised three parts:
I was responsible for construction of the physical system, as well as high-level integration and project planning. Starting from an existing, open-source design for a 3D plotter, I replaced as many parts as possible with alternatives that could be laser-cut or 3D-printed, to maximize the ability of makers to recreate or modify the design using standard tools. This was a great opportunity to learn about CAD tools like Solidworks, and methods for rapid prototyping and fabrication.
This project was an extraordinary amount of fun. Though the device we built was not particularly novel, it was exciting to take on and coordinate a project with so many separate subsystems, and to finally have it work all the way from input image to output drawing.
Our team competed in a “Dragon’s Den” style pitch competition with executives from Orbis Investment Management, where we won second place (and a $1000 prize) for our design and associated business model.
Contributions: Concept, Implementation (Mechanical Design), Report Writing. I completed this project with four other (extremely talented) students, to whom I owe a great deal: Behzad Abghari, Esther Roorda, Alan Daniels and Pak Ki Lam.
