I'm with Craig on this one, I know a lot of people on CD would be interested especially me. We have noticed with our Gyro that it walks and that over a bump or two its completely off.

More info would be amazing.

With our filed oriented steering we have not experienced much trouble with gyro drift. Not sure what we are doing right to avoid that. We're not doing a lot of frequent bump crossing so maybe that helps. We do have a gyro reset button at the driver's thumb. If he feels it is off he can quickly reset whenever the robot is square with the field.

indubitably

Two things we are doing is fine tuning the gain on the gyro and we have a temperature sensor.
