Im wondering, would you want the high torque on the outside of the wheels or the inside? when you are leaning on the outside edges of the wheels your bot is more stable, which would be ideal in a shoving match, having more power to steer under heavy resistance
but having the outside edges down at high speed would also be good, if you are going to make high speed turns, to keep your bot from tipping
I could go either way on this one, depending on the game itself.

im with ken on this. no need for a universal. a "conventional motor>gearbox>wheels" can all rotate. no problems there..
hmm. well it does depend on traction and speed but a high speed robot will be faster at zero radius turning (as in angular acceleration) if the track width is smaller. but also harder to control that way. if you do the high speed on inside, high torque on the outside, and have all four wheels on a sort of parallel 4 bar link, and at "neutral", the robot is on about the "center" of the cone, you lean all 4 wheel to the left and the robot turns left in a gentle swoop. so itll kinda handle like a motorcycle. kinda...
but thats offtopic. sorry.
um. personally i think i would go with torquey on the inside. faster to turn with even massive "low gear" and more stability at high speeds.
