https://youtu.be/q9p56CIYZ_k I truly enjoy mechanisms, thus when a recent YouTube video appeared in my YouTube suggested video feed of a CAD animation of a simple walking mechanism designed by thang010146: https://www.youtube.com/watch?v=1ht3nz4YgGY I just had to try to recreate his mechanism for 3D printing. thang01014's mechanism was designed to be powered by torsion springs or rubber bands, but I decided to design a motorized version. After a long afternoon of design, 3D printing and assembly, "A Simple 3D Printed "Walking" Mechanism." was the result. And as indicated in his video, the mechanism indeed powers over "rough" terrain with ease. My implementation of his design consists of eight unique 3D printed parts (twenty six total 3D printed parts as there are numerous duplicates), a motor, battery and battery connector. As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes. Designed using Autodesk Fusion 360, sliced using Cura 4.6.1, and 3D printed in PLA on an Ultimaker 2+ Extended, an Ultimaker 3 Extended and an Ultimaker S5.
