Now that it is install on the robot, it seems not to respond the same. We get what appears to be a rate return instead of a position. The z angle changes as we spin the robot (our robot spins in circles really well), however when we stop the angle returns to 0. It appears like it is tracking the rate and not angle.

Does anyone know of a failure mode where this would happen? Any suggestions?

Thanks
Hi! You may be accessing the raw sensor outputs instead of the integrated sensor outputs. If you're using LabVIEW, you'll want to access the sensor using the Gyro Angle or AHRS Angle vi's.
