This is a link post Automated Pendulum Control
In theory it's easy, but making this actually work is still VERY IMPRESSIVE:

Swinging up a pendulum. On a pendulum. On a pendulum. And holding it.

This is a normal post In Alasdair Reynold's Diamond Dogs
there's a lethal trap based on a triple pendulum, on the basis that its movement is almost impossible to predict in real-time even for an advanced AI with big computational resources

This is a normal post Never underestimate the difference an extra dimension makes.
I don't know if Reynolds was anywhere near right, but bear in mind that this one only moves in one plane.

This is a normal post That's just witchcraft
I've played with one of those control rails back in Uni. It was hard enough to get a single pendulum to stand upright. Doing so with three has to involve some form of sorcery.
