A Disney Research SIGGRAPH 2013 demo of an interactive system that lets non-experts design animated mechanical characters. The user sketches motion curves and the system generates optimized mechanisms and gear trains for 3D printing.
HN cites it as an example of computational mechanism design, especially in threads on gears, linkages and animatronics.

Here's a good Siggraph 2013 demo about "Computational Design of Mechanical Characters" from Disney: this video
Is there a standard way to formally describe a mechanical machine? Similar to how a .obj file defines a 3d shape? Some standard way of describing piece types, interactions, properties, movement ranges, etc. Then one could have a computer use the format to learn/find interesting configurations based on a catalog like [LINK] especially if paired with simulation like done in this Disney research project using gears and linkages this video
This reminded me of a recent paper on automatically designing animated mechanical characters. Some of these movements could be used to incorporate different kinds of animations into these characters. this video
