I recently made this a vision-controlled pen plotter:

People seemed to like it and were asking about it, so I thought I'd write about it here!
# Story
I recently started working as a computer vision software engineer at a [robotics company](https://www.monumental.co/).
This is my first time working in the robotics industry, and I've been thoroughly enjoying it.
I've found it to be insanely satisfying to write code that translates into real-world, physical machines completing tasks intelligently.
Of course, this is facilitated by physical machines - hardware. Motors, electronics, springs, power converters, 3D printed creative designs, and all kinds of stuff I have never worked with before. Absolutely fascinating.
So, I decided I'd take a stab at this hardware stuff in my free time.
The project I decided to go with was building a robotic pen plotter.
Ok, so I want to make a pen plotter. The rough idea in my head was that I'd make a robotic arm with two rotating joints, like a double pendulum:
