thats the thing though; the only time that the mecanum wheels are acting like 'traditional' omni wheels are when the bot is moving at any angle between forward/back and side to side. when moving forward/back, they act like treads. when strafing, they act like propeller blades.

<hare-brained idea> on that note (prop. blades) i'd also like to throw out an idea that i got from watching the bots strafe back and forth. what if you were able to change the angle of the rollers? decreasing the angle would move you less distance per each "wheel" rotation, but would give you more pushing force.the angle of the rollers could be changed by a mechanism similar to the ones used to change the blade pitch on prop. aircraft. </hare-brained idea>
