Fully Parametric Robot Arm

Parametric Robot is my attempt at making a one-click solution for a custom robot. You type in your desired payload and arm length and
the .scad file chooses every bearing, motor, profile size, and part dimension accordingly.
My current result does not represent my vision where it also takes stresses within the 3d printed parts into the equation.
But i have learnt a lot about the logical aspects of design and that even formal definitions
need the same design finesse in topological arrangement as it would be when constructing in 3D.
I can see how these aspects might play a big part in the development of standards, like for screws, bearings, bottles and ship containers.

It's based off of this: ( https://www.youtube.com/watch?v=PibS60HisO4 )
