The simplest hexapod (Stewart platform) is a tool suspended by six wires.
The wires are attached approximately at 3 widely spaced points from above,
and connected to 3 points on the movable platform. This allows the platform
to be moved within the space, and to be tilted, as well.

If you've ever studied the mechanism used for full-motion flight simulators,
these are Stewart platforms. Turn it upside down and it makes a good
machining system, too.
