You're pulling my leg

In the winter of 2019, from so much pressure from my good neighbour Alain, the Author finally gave in and decided to start building my real legs. (don't hold your breath, I'm not about to walk anytime soon).

 

There were many challenges ahead, but the major obstacle was to have some flexibility to the legs. Adding motors was out of the way due to time, high cost, high power requirement, and all related to uncertainty and unpredictability.

​

The addition of new legs was the most laborious task to date. It's not only the legs, but also the lower waist section that will be joined with the already assembled lower stomach. Together, they will provide tilt and rotation movement to the waist.  Much the same as the already existing tilt mechanism, the rotational action will also incorporate ball bearing construction. Even though there are no motors in the legs, there are two servo motors with gear and gear box for the rotation movement. They work together in a push-pull action within the gearing system.

 

The original hip structure design had poor structural integrity, resulting with fractures and dismembering accidents. It took the whole winter, with multiple redesign and prototypes to finally achieve satisfying and gratifying construction.

​

Considering the small printing size limitation of the Solidoodle-2 printer, the bulky parts of the legs had to be divided in several prints before assembly.  As part as the following cosmetic surgery, for optimum appearance, the gap section between the assembled parts were stitched together with a hand held pencil size 3D printer. Followed with filing and sanding, And finally brushed with acetone to give a nice shinny look.

​

At long last,  I can now stand, sit, go on my knees, sit on a chair or directly on the floor, and much more.

Being able to go down on one knee, I'm now ready to pop the big question.

Standing on my two feet, I think I looks quite handsome with my 5 feet 12 inches

(wait . . . wait . . . wait . . . Ahhh now you get it !)
