[Hawiian Cadder]

it is correct that they do not create a bump, however all of the rollers are not at 45 degrees relative to the ground, due how one roller is at the begging of its for lack of a better word contact zone, and the other is at the end, they are at a slightly different angle relative to the ground. while going forward or backward, or while strafing, this should not be very noticeable, but while going close to diagonal it causes the robot to move in more of a very small zig zag pattern, which causes accelerometer white noise. this caused problems for our attempt at a robot that could stay parallel to the field at all times. it did not work while going diagonally.
