I'm assuming that Arhowk tried this with the roboRIO's built-in accelerometer. Has anyone tried something similar with accelerometer data from the navX MXP expansion board? If integrating that data can give a reasonably accurate velocity, I could see this being another solution for simple autonomous motion profiling, rather than using encoders on the drive.
