When we stop the robot the change in angle is the same as when we moved the robot. Mostly it is a lot more than a couple of degrees per minute.

We ran the code and didnt move the robot for five minutes. During that five minutes we read 0.015... degree from gyro. Than we moved the robot and when we stopped the robot we had the same problem. Gyro continued giving different angle values.
We are making this up as we go along - please don't confuse us by telling us the way that it really should be done. - dlavery [more]
