Re: how does one go about making a 6 wheel config drivetrain?

I don't understand your question about being pushed.

There is significant weight added. However, the bonus to that is that it is also lowering your CG. Omni wheels weigh just as much as regular wheels in most cases. You lose no traction. In fact, if using a grippy tread, like the KOP wheels or IFI nitrile tread, you gain a little traction.
say a robot is to come and push against a corner, wouldnt you spin and not be able to push back, if u have omni wheels for front and back?

and for the 1/8th lowered, why would u only want 4 wheels on the floor at the same time? i wouldnt think that the weight added would be worth the extra 2 wheels if u dont use them. you lose traction for the wheels that arent on the ground, say someone bumps into u around that area, you would spin

im not bashing 6wd, im trying to find out pros and cons
