We are trying to have each motor at the same speed and if the encoder notices that the speeds aren't the same we would like for the slower one to speed up or the faster one slow down so the speeds are equal. We were thinking that the motors start at the same speed but after a little while of running the speeds my get off, if they do we want to make them equal again. The loop essentially keeps the motors the same speed These motors are controlled by the driver and both with one button.
