Re: Stabilizing robot on bridge with gyro or accelerometer

I suppose you could have it drive forward a certain distance, controlled by encoders, or time based, but that's tricky and tweaking it takes a long time and it may be too variable.

Thanks Matt, how sensitive is the accelerometer to vibration and motion? I assume this means that it gives back a noisy signal that's harder to make sense of? Will the bridge rocking back to level be any problem with this? We've never really used the accelerometer on a competition robot.

Yeah, the Kalman filter sounds nice. I've read a little bit about it and my first impression is that it's a little too advanced for most teams, including my team. But all the power to you if anyone could get it working with better results. That would be cool.
Honestly, if you look past the vocabulary and linear algebra (so just use single variables), Kalman Filters are not that bad.
