Wacky Walker

Perhaps the most convoluted walking mechanism I've ever seen, "Wacky Walker" was a lot of fun to design, 3D print, assemble, test, and, most important, watch in action!
The inspiration for this model came from JK Brickworks Lego reproduction of a late 1980s toy known as "BearMobill" (yes, me neither).
The model incorporates a motorized chassis hanging from an oval track having free rotating legs. When the chassis passes beyond the front pair of legs, it's weight is tuned just enough to flip the oval track over bringing the previously rear legs to the front to repeat the process.
Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s.
