yea, go to yahoo and look up 6DOF (six degrees of freedom) you'll find quite a bit. I started looking at this stuff a couple years ago when trying to develop anti crash technology. Turns out this is very easy (relatively speaking) Problem is cost of components. I can make an anti crash box for less than a grand. But to sell it to the public means that device would be in the 5k market. Not too many people willing to pay that. Well, then I ran into the 6DOF stuff which kindof put the project on the back burner.

By Anti- Crash I want to take a plane, heli...doesn't matter get it in the air...flip it twist it...turn around and walk away with out a problem and have it land itself. Also, what to have it avoid people. Still not a problem. hopefully by this time next year I'll have something working
