First of all, I am truly sorry about the rough work and bad communication skill to describe my creations. Most of my work are done by on going. Never really design it on paper but only concept in mind. However, since most of you guys are makers. It wouldn't be too hard to figure how to connect these joints and parts. There's no official way to hook them up. Or maybe the way I use is not the best way. You might came up much more brillant tricks to assemble it.
I used a lots of 4-40/M3 bolts and aluminum tubing(exact like the image I attached in gallery) in size OD 3/16" and 5/32". Tube are used for reduce the firction in "supporting servo arms".
Anyways, in this set I have used 11x 9G servos, 2x 10mm LEDs and mounts and use Arduino UNO with expansion shield to hook up electronic parts.
About the programming I just put all servos in the loop from position 80~100 and it coincidentally looks like walking, even thou it's not the way I am going to make it walk. Haven't done the programming part yet.
Again, sorry for rough design but it would be good experience for doing trouble shooting. (Don't bite me!)
For shouder and arm parts. You have to finish to assemble arms and shoulder first before connect shouder to body. I suggest you try to fit them first before you really tight them up on screw or whatever.
This video shows the mistake I made. I shouldn't connect shoulder before complete the arm.
In all STL files I only made one side for the reverse part, you just reverse the Y to -1 in your favor slicer application.
