Gyro Filter

[Lloyd Burns]

Check the CD search feature - use "gyro filter" as the search parameters . The second oldest result I got was the Techokats' .pdf on using the gyro with a software filter to balance on the ramp.

The big problem with the gyro, if it is used for dead reckoning, is that it goes non-linear at turn rates less than 90 degrees/second. This is the turn rate of your forearm as you raise it from horizontal to vertical over a whole second ("one steamboat"). If your robot turns only that fast, it will appear quite sedate. If it turns faster, your robot can't tell where it is heading.
