They have a 5fps/16fps (or 6/15 I forget...). The high gear is very fast, and the low gear is putting out a significant amount of torque, probably just around traction limited knowing them (which is a lot, using gum rubber roughtop tread... which is about the highest coefficient of friction you can legally get for wheels). So, I'd say they can push if they need to; They're just too busy scoring.
I don't think they are using bumpers, and I think they are in the 110 lb weight class. So, they are at about 124lbs, with battery (maximum). I also read something about them weighing about 85lbs, because they were planning on adding ramps. If they didn't add weight to get to 110lbs, then they are really scrawny at 100lbs, with battery. That hurts their pushing power. 100*1.3 is equivalent to 150*.867, about the amount of traction advantage a full-weighted 4ft class robot would have with something even less grippy than the old wheelchair wheels that were in the kit. They have the torque, and they have the treads, but they are lacking the weight.
