Humanoido Extensions: Worked progressed on the Upper Body Torso Mobility Core. It's now apparent that the omega plane will need bearings. I believe it's possible to fabricate a three dimensional cylindrical bearing to provide increased support and reduce upper body flexure. The rotation results in an eccentric, therefore cylinder placement requires attention. Tests show that certain plastics have very little friction when placed in plane to plane contact, not unlike a teflon surface bearing. This approach will be incorporated into initial designs.
