This is my 3D interpretation of Amanda's walker linkage system. I'm planing to do full scale model, but first I need a workable printed model. Scale is 1:1 to Amanda's Mathematica's units. Her thesis on this subject can be found here: http://www.amandaghassaei.com/mechanical_walking_machine.html This is first model and it is not (properly) walking yet. It's basically a proof of concept. I'm allready working on a second model, just arhiving that one here. Printed on Ultimaker derivate: Troublemaker. For one leg you need 2x 75, 2x 56, 77 and 77koleno. Shaftgear has "integrated" 26 shaft, so you need that one too. Be aware of two types of legs avalible, choose those you can print.
