If you were at SVR you probably saw our arm. A lot of programming went into keeping that monster controllable.
A description of the physics of what I am referring to can be found at:

by using an electrical damping term, not depending on mechanical
damping, you can get improved speed and control, subject to any slop
in the mechanism, of course.
