Has 6 wheeled designs surpased tank treads

[Pat Roche]

Paul, the kinematical physics say that surface area does not matter. A wheel and a track will slip once the coefficient of friction is broken regardless of surface area. I find that tracks handle vertical obsticles(step, bump, etc.) better than a six wheel bot because the track is always in contact with the edge of the obstacle. I guess all and all I believe that both have the same basic physical advantages. It's more a matter of preferences.

(What I meant in my previous post by pushing power before was that the bot itself was a very strong machine)
