6DOF Joystick Stewart Platform Remote Controller
You can find out about this and many more robots @ http://marginallyclever.com.
So... I suck at Kerbal Space program. I needed a better joystick to fly with and I know that - in theory - a stewart platform can be used as a 6DOF joystick. Unfortunately they're really hard to get. So I figure I'l just build my own. Maybe I can get the Minecraft guys in on this, too.
This is as far as I've got so far. If you know anything about forward kinematics, I'd very much like to hear from you.
