The signals are analog, and you have to make sure you dont corrupt them, like tie-wrapping them to the power leads for the motors or other wires carrying heavy current.
Also make sure the gyro is getting the correct voltage on its power pins.
also, are you sure you are turning the gyro on the right axis? it only senses rotation on one axis.

When the terminal output indicates that the gyro is in fact turning, then yes, the voltage changes appropriately. However, the voltage doesn't always change when the gyro is turned, and the output on the terminal supports this. Also, there is no interference with other high-current wires becase the gyro and controller are temporarily disconnected from the robot.
Also, we looked at the documentation about the gyro, and when we rotate it about the axis normal to the specifications, the gyro angle did not change. However, when we rotated it along a different axis, the gyro angle would change. But once more, this change is not always the correct angle.
Would you recommend trying out a new gyro? If so, are there any good recommendations?
