Fully 3D printed StrandBeest (Theo Jansen Mechanism)

Fully 3D printed StrandBeest (Theo Jansen Mechanism) Theo Jansen's mechanism is truly fascinating. Many designers have created and shared their own versions but they all seem to require rods, bolts, and nuts. While these components are easily available for purchase, it's not advisable to visit local stores during this quarantine period. So I decided to design my own version of the mechanism with fully movable joints that can be printed. I conducted several trials and tests on the joint dimensions. For instance, the links' joints should have a clearance fit, while the stoppers (similar to nuts) need to be tighter to prevent the pins (bolts) from loosening. I also created the primary center frame to mount the motors - each motor controls one side. This is the first stage of my project. I only installed one motor and it was able to move in a circle, but with some struggle. The full concept involves building a remote control circuit so that this Strandbeest can be controlled moving forward, backward, and turning, just like a remote-controlled car! All parts are printable. Some components might require using a file to expand the holes, but it's still relatively easy to assemble.
