Re: Integrating accelerometer output

I tried it with a vex robot prior to the 2007 season, the code is in this old post of mine:

Based on my experience the kit accelerometer would be no good for an FRC robot (at least for inertial navigation). It may be possible with a better accelerometer, or a higher resolution ADC than that of the RC, but my stuff with a vex robot was off by a few inches when traveling less than 10 feet, which would put you off by over a foot when traveling a full FRC field.
