While watching the Will Smith movie "I, Robot" (yea I know its a stupid movie, but it just came out, don't judge me!) I saw vehicles which had "metal balls" in place of wheels, and I thought, how the hell would that work, and heres how I think it would work. A hollow metal ball, coated in a gripping
surface, with permenant magnets embeded inside the ball, would be contained in a recessed area in the vehicle (the ball well) that would be sized so the ball couldn't fall out, around the inside of the ball well would be place electromagnets, under computer control, would levetate the vehicle away from the ball, and by truning the electromagnets on and off (and reversing their polarity) you could drive the ball in any direction, move all balls forward and you move forward, backward, backward, some forward some backward and you spin, basicly the car could go in any direction it wanted, want to park, just drive sideways, and no flat tires ever again. So what do you think?

Has it been since 2006 since someone poured brainpower into this hole. The time has come again. Can the fish move the bowl? Ponder the mystery. Ponder, damn you! [bungston, Jun 10 2009]

I think point contact area instead of line. I think very little or no traction. I think very low power brakes. I think very, very dangerous cornering (unless you're able to conduct huge torque forces to the balls to restrain side-forces during cornering, without affecting forwards rolling resistance).. |

You mean me? I assumed little robot hamsters were inside those big balls, communicating wirelessly with the driver. |

If you were magnetically levitating atop a ball containing permanent magnets, and you turned off the electromagnets in back of the ball, the vehicle would fall down onto the ball , pushing it forward (maybe). But the vehicle cannot fall down indefinitely. You could turn the electromagnet back on and come back up, then off and come back down, each time nudging the ball forward a little. Pretty bumpy ride. |

I think Ling had a posting for a ball-wheeled vehicle around here. Let me look. |

It could be done; but, as [Custardguts] points out, there's not much point, and it would be horribly power hungry (electromagnets hold the vehicle up the whole time, as well as counter-acting all acceleration forces). |

I don't agree with that mfd. What if you came up with a great idea for a heisenberg compensator. The name and function would be nothing new. But the actual explanation of how it could be made to work, now that would be a miracle and a novelty. |

I agree with zeno: a legitimate if poorly spelled speculation on how a solid unconnected ball wheel could be made to propel a vehicle. |

Sorry, I'm still a little preoccupied with //its (sic) a stupid movie, but it just came out//.
Is there really some part of the world where this film has just come out? |

"It could be done, but...there's not much point, and it would be horribly power-hungry" |

I'm not too happy about the //stupid// part either... |
|
| |
It was in a movie, but it appears to be a legitimate attempt to explain how such a thing would function. It's also sufficiently different from the other, similar idea, so I disagree with the mfd as well. |

//It just came out\\ [Hirudinea] has been lurking for years and is now posting the ideas he/she had in all those years. |
|

Just to clear up, when I said "It just came out", I had the IDEA when it came out, I just joined Halfbakery a few days ago. |

RUN ! RUN ! SAVE YOURSELF ! Get out while you can ...... it's too late for us, but you might be able to escape ..... run for the escape capsules, and DON'T LOOK BACK ..... |
