Detecting Edges of Objects using OpenCV

I've been starting to explore different methods for figuring out the location of drawing surfaces for my yet-to-be-named Drawing Robot. I have a few options available to me for use, which mainly include OpenCV, for both C++ and Python, and the imaging processing tools within MATlab. There are a few differences between these methods, and I've … Continue reading Detecting Edges of Objects using OpenCV

Drawing Machine, with a Brain

Drawing machines are a decent project to build from scratch, but they are not complex robots by today's standards. They use open loop motors, and the kinematic model is relatively simple and well-understood. Open-source firmware like Marlin  can be used to control the robot like a 3D printer using G and M commands, and is easily … Continue reading Drawing Machine, with a Brain

Sketch Robot: Eyeing the Competition

I've been spending most of my free time these past few days researching existing concepts for drawing robots, exploring different unique methods, and narrowing down the scope of my project to something that could actually be realized. I've found quite a few different ideas floating around out there, some with obvious design issues, but many … Continue reading Sketch Robot: Eyeing the Competition

Construct Project: Improving An Amazing, but Flawed Large-Format 3D Printer

Construct Projects are things that I have worked on while employed at The Construct, the makerspace at RIT. I officially work here as a lab manager, but among my many roles, I am also a WebDev, Graphic Designer, Systems Engineer, and even a  Carpenter!  We’re a small space with a small budget, so many of … Continue reading Construct Project: Improving An Amazing, but Flawed Large-Format 3D Printer
