##### Could a sphere 10-25% enclosed by supports be moved in every axis?
« on: 10/10/2016 22:19:25 »
You know the car in iRobot driven by Will Smith with sphere's / ball's as tires?

Even though it never really worked in reality (build but not driven). It's still the easy version of a 360' sphere rotation system because around 75% (3/4) of the sphere are surrounded by support structures.

What I wan't to achieve is around 10-25% support structure around a sphere and still be able to move it around in every single axis possible.

If you didn't got the hang of it already you should Imagine a soccer ball (football!) and one single point on it. The system should be able to point this system in every single direction a sphere has: up, down, left, right, up-left... You get it, I am sure because we all know pi is there and the direction of a sphere are infinite.

I need to build this. But I am not sure how to get behind the problem of supporting it and still leave enough space for (okay let's face it) thrust. It's not a tire. It's more like a spherical turbine engine wich needs to be tilted in every direction in order to create revolutionary maneuverability. Since a turbine needs to suck air in and "breath" it out somewhere else, in our case the opposite side, I need to build the 360 spherical rotation system with the least amount of support structure around it wich is actually rotation the sphere thruster.

I can see the overall result right in front of me. Thats why is say no it's for sure not impossible. Nothing we human's every have imagined is impossible... When it is still in physical terms of course... As Bruce Lee once said: "Impossible is just a big word thrown around by small men."

If you don't have a answer but a kind of technology already existing in mind, wich is similar to what I wan't to achieve... Please tell me.

Thank you very much.

Look at a computer trackball.
