Rover Wheels HELP

Hey I am looking for a set of wheels. I once saw them at a robot site, but now can not find them again. They are servo driven wheels that are connected to another servo so the wheels can rotate 180* "Rover Style" (allowing the robot to change direction without changing its facing direction.)
Any help would be appreciated.

    Try www.lynxmotion.com

    Neat articulating chassis, but bucks. They seem the most commited to mechanical variations in servo driven bots.

    I think you are thinking about an "omni wheel"... there are many places to get them including Acroname.com

    Here is a link...>· http://omniwheel.com/omniwheel/omniwheel.htm

    thanks for the links but these are not the ones I am looking for.
    I guess they are almost wheel arms. they allow the robot to raise and lower its self.
    IT WAS AMAZING!!!!!
    and now gone in the wind....

    I didn't see it on the linxmotion site just now, but I believe you can (and I remember seeing a picture) use the servo brackets from there and mount you "drive" servo (continuous rotation) to the output of your steering servo with components from their "erector set" stuff.

    Special_K -

    The real deal, the Mars Rover Landers, use what's called a "rocker-bogie" independent wheel suspension system, and I too think I to have seen it simulated on the Lynxmotion web site with their "Erector Set" servo mounting parts, as John did. I'll see what I can find for you, presuming that's what you're after.

    Regards,

    Bruce Bates

    I couldn't find exactly what I was looking for on the Lynxmotion web site, but perhaps the following is what you were looking for, regarding a servo driven articulated wheel:

    Bruce;

    That's the one I was thinking of. Thanks for helping K (and for confirming I'm not going insane).
