Let's say the robot doing the t-boning is geared at 12.76:1 with 3 cims per gear box, and semi deflated tires. Could it push the other bot easily?
What if the t-boning robot were to weigh more, say around 165 lbs. Would that allow the t-boning robot to push the second bot more easily?
In a head to head pushing match, could the t-boning robot described in the previous question easily push a robot that is not geared as high, has fully inflated wheels and weighs closer to 145 lbs?
We ask because we are waiting on our first set of pneumatic and probably won't have a second bot to test on?
Thanks for your experience.

My suggestions would be to perform some simple testing with your drive base and a bathroom scale. Tire pressure is an easy variable to change. See how much pushing force you generate with "fully inflated" tires and "partially inflated tires" (maybe a couple different levels of inflation?). Place the scale against the wall, drive the robot into the scale and record the peak force before the tires slip, then pick whatever pressure gives you the best performance. You may also consider configuration with different pressures at different locations as that may yield a different result.
It's safe to assume about the worst case scenario for the force required to push that robot sideways is in the 205-215 lb force range. This assumes a 147lb robot on an aggressive rough top tread.
If you're planning on playing defense, you can't really plan for any possible opponent configuration, but you can certainly optimize your configuration for the best results.
If you have any other questions, feel free to send me a PM and I'll see if I can help you out.
