Primo

LEVEL: BOSS

DISCLAIMER: I have absolutely nothing to do with people from Primo. I have never met any of them and I have no financial reason to write about their product. But I can't help it because it is awesome!

Primo is a toy that consists of three parts: Instruction box, commands and a small car robot called Cubetto. By placing commands in the Instruction box, you need to navigate Cubetto home. You can (should) read more about it here.
This turned out to be quite a bigger project than i anticipated. Honestly, I am probably the one to blame the most. I took idea for Primo and changed a few stuff. That, in turn, made me change the drawings for the laser cutting parts, so in the end, I basically had to redraw the whole thing from the scratch. As I find time, I'll post a guide on how to build one yourself, my way.
