Using navX MXP to get robot velocity

[Skyehawk]

Now that you bring it up I am really excited to give it a go before the season starts. Too bad I am a college student and don't have access to the hardware for this endeavor.

The way I see it though the noise of the accelerator will result in an error of many magnitudes greater than the error in robot velocity from drive train encoders.

While we are on the subject of sensors to obtain robot velocity, has anyone tried multi point sonar (or other range finder) velocity? Not that it would be in any way practical, but just a thought.

I don't mean to hijack this tread in any way, sorry if I do.
