why do we actually need these?

Couldent we just use limit switches on each module? since the 2 wheels on each side are linked together,

Like in full-crab mode, have one joystick for "gas" and one that turns both sets of wheels the direction you point it? and the same for "ackerman"and "Slolam" modes?

And maybe have something coded so they return to the middle if you let off the sticks?
or is there something im missing?

also what motor could we use to turn the modules? ive seen alot of teams use globes,but they're not the fastest thing...only 100rpm
