Actually, I misspoke. I forgot that I'm using the IMU for turn rate also. But mostly I'm using the IMU heading so that I can "Turn 10 degrees left (of where you are now)" and it'll do it. The IMU heading drifts but I use the GPS heading to determine how much I need to turn, so it's not a big issue. --- [Visit Topic](https://discourse.ros.org/t/tractobots-my-attempts-at-field-robots/1486/57) or reply to this email to respond.
