Compass and/or Gyro

Technical Sensors

We are trying to determine the best way to get a true accurate angular heading of the robot.

2 Years ago we tried using the rate gyro, to some success, but to abrupt of a turn, or a jolt and we would lose our heading. It was however successful enough to help with our autonomous.

I’ve read of the idea of using a compass to periodically reset the gyro, so here is my question.

How would you determine when it is appropriate to reset the gyro’s heading using the compass?

Is it better to do it based on an error percentage between the 2 sensors? or a time based reset period.

Thanks,

You should try using this year’s gyro before deciding it’s not good enough. FIRST massively upgraded the gyro between the 2008-2009 seasons so the current gyros are much better. Not sure as to how to use a compass to rese the gyro sorry.
