Waist Rotate Biped

I’m interested in building one of these:

What is the parts list for this? I just don’t understand how to get the waist to rotate, I’m assuming it’s using this component:

Another big mystery is, how is the servo for the head mounted? Are there more images, particularly the back side?

:question: :stuck_out_tongue:

Here is a thread that has a couple closer images. This assembly is a little tight to say the least. The robot was disassembled in order for us to build the johnny 5 prototype a long time ago. If I remember correctly the battery was added to the back of the bot in a backpack configuration. Beyond that I would have to rebuild it to really say anything more useful. Besides from the assembly being tightly spaced it wasn’t a terribly difficult build.

Thanks Jim, I appreciate the link. I remember seeing this sometime ago but couldn’t remember what the thread name or when it was posted 8)

The biped humanoid with waist rotate is such a beaut!
