I got our compass working now on the Geobot. Its a bit tricky to deal with the numerical roll over from 359 to 1 degrees but I found a simple solution. Anyway, the robot takes a bearing upon turn on, and maintains it within about 2 degrees tolerance as it pounds its way across the rocks in our testing area. Its the damndest thing - I set the robot down, and it swerves around avoiding rocks and such, then turns toward the original bearing when its not hitting something! Very cool to watch.

I did run into one issue with the Devantech compass, it would not calibrate per instructions. I kept on rotating it and the done line never went high. I finall in desparation used the old cal proceedure with 4 points at 90d, and that worked. Id be intersted if anyone had a similar problem with thier compass?
