Re: Gyro not accurate - Problem
I don't know if this is an issue with the gyro from the KOP, but we use an ADXSR150 in a Robo-Magellan robot and found that the gyro gives different values when rotating clockwise vs. counterclockwise. So, when doing integration/averaging we use different denominators for values above and below the centerpoint.

Until we did this, it was impossible to rotate one way and back and get a angle value close to the starting value.
