Has 6 wheeled designs surpased tank treads

[crazykid234]

This year team 234 used the tank design mostly because it allowed us to fly over the six in. steps. again, the game dictates the design.

All you tank tread lovers, educate me on the following things:


1. Show me the math that shows tank treads have better pushing force (traction) than a wheeled design.

2. While doing number 1, assume whatever tread material you use for the tank tread can be wrapped around a wheel.

3. Leaving the obstacles out of the equation (stairs, ramps, etc.), why do certain vehicles have tank tread designs (tanks, excavators, snow mobiles, etc.)?

4. Again, leaving obstacles out of the equation; what advantages are there for FIRST robots to use treads? If you say pushing force, or traction; then prove it with math/physics.

I look forward to the range of answers.
