That works great in physics class, but is a bit tricky in the real world. Have you considered using an encoder for measuring distance?
Early on we did some testing with accelerometers - it was difficult to simply measure velocity, let alone distance.

Yes, considered encoders, but with mecanums and traveling any direction, I'm not sure they would be very accurate ether. The any direction part makes an idler hard and the mecanum slip make encoders on the transmission hard.
