This is a  new version/design of a simple quadruped robot. The robot should be easy to print on a  hobby grade printer (the one depicted was print on a Prusa I3Mark2).  The assembly doesn't requires screws/bolts , the parts click-fit together (0.3mm of tolerance). For the electronics you will need 8 servos (9G.) a microcontroller a servo controller and power. The model in the picture use the following: Adafruit Feather ( https://www.adafruit.com/produ... ) Adafruit 8 channel Servo FeatherWing ( https://www.adafruit.com/produ... ) 4xAA Batteri holder ( https://www.adafruit.com/produ... ) 8x MG90S High Speed Micro Servo Metal Gear The robot was designed using OnShape, a browser based parametric CAD software package. You are free to copy/customise the project. The link to the project is: https://cad.onshape.com/docume... You can read more about other quadruped bots at my blog at www.burningservos.com and on twitter @ronaldxjt. I'll add a link here to an Instructable I'm currently working on.
