Pythagoras the drawing robot

A laser-cut delta robot that can draw better than I can

Aaron Fan is a robotics student at Georgia Tech. Over the past few months he has been regularly updating his website with details of his current project: Pythagoras the drawing robot. He covers a lot of ground, from the mathematics to the coding and hardware design.

I love this project because it ticks all my boxes: the parts are laser cut, the design is open source and well-documented, and the finished machine is equal parts ingenious and pointless. Check out this post for an overview of the project, or take a look after the break for video of the bot in action and examples of what it can draw.
