Re: Drifting Gyro with EasyC

I know that the gyro was a different one this year than last cause we couldn't simply change between the two without some very major changes to the code.

I will tell you that the gryo will slowly drift even when just sitting. We did some experiments in 2005 to see if we could get absolute positioning working with our swerve and found that it would get almost 45 degrees off with like 720 degrees of motion. Of course this was a drastically different gyro but we have found the same things to be true of both this years and last years gyro.

While I don't know if this is significant for a small bot I will tell you that it is meaningless noise for the operator of a FIRST bot. I barely notice when the gyro drifts because there are so many other factors that influence that bot.
