This is a MakerBotable kit to modify a RoboNova-1 and add another DOF so the legs can pronate and supanate while keeping the height of the RoboNova-1 very nearly the same as the original 30cm height ... and this allows for the c.g. to remain lower for more stability. I upgraded the servo drive horn with splines on the inside bore ... albiet I don't have a caliper that small ... I'll can only eye-ball and guess.

This kit will make your RoboNova-1 slightly wider and thicker, but even side-by-side they appear very much the same size.

And as usual, every part here is designed to be MakerBotable with a CupCake MakerBot ... except for the rubber band ... get one from your local post office!

I wish I had a MakerBot to actually build and test my creations!

See a video demonstrating the added value and size comparisons.

I plan on uploading the aluminum bracket SolidWorks .SLDPRT files to the 3D Content Central Library soon ...
