Re: 2 motor drive VS 4 motor drive

it all depends upon the application and drivetrain. we use mechanum drive, so we use 4 independent motors and gearboxes. we have used mechanum every year but '09, and we honestly have no problem w/ pushing power or inclines. we also have not had any chatter problems, although, in 2010, crossing the bumps took it's toll on the bot. we even managed to drive surprisingly well on 3 motors when a gearbox stripped out a pinion.
if your not gonna be pushing a whole lot, 2 motors will work fine. we use 2 motor RWD tank drive on our t-shirt cannon that is probably 50% heavier than a competition robot, and it works well.
