Recently, I got very enchanted with a few robots that I saw on web and YouTube videos, which use a very simple mechanism to walk, with only three servo motors.

So, I started to design my own three-servo-walker, that I called "STEGObot".

The design is inspired by a stegosaurus toy of my son, from Jurassic World movie. I started with some hand drawings in cardboard sheets and cutting the parts, then joining them all with hot glue.

In the video below you see the cardboard prototype that I made to test the mechanism and to have a good perspective of the parts.

In the next days I'll start to work in the final model, and make the parts with high impact polystyrene. 

On the back of the robot (the spikes) will be placed a big and exotic PCB, where will be attached an Arduino Nano and a NRF24L01 module for remote controlling. So, this PCB will substitute all that mess of wires you see in the video and pictures.

In this post you can also see the Gerber files of this PCB, which I call "STEGOboard". The PCB shape was made with Inkscape and PCB schematic with Fritzing.
