So you saw our video and you've fallen in love with Fixbot, have you? That's okay, it's understandable. We've fallen in love with it too.
We have some great news! You can build your own Fixbot too, provided that you're okay with getting your hands dirty and that you have access to a Makerbot / RepRap / Ultimaker / 3D printer. You don't need to be a code wizard or a da Vinci descendant to get through this instructable, but it will help if you know a bit about how to upload sketches to an Arduino.
Join us on a journey of bearings, nuts, servos, lots of wires and some ABS, and by the end of it, you'll have your own Fixbot to play with!
P.S. we'd like to give a hat tip to David Chatting for his trigonometry skills and to Benedikt Gross for his movement learning code!
