ADXRS150 gyro yaw rate sensor

[Brian M.]

We have purchased a yaw-rate sensor from analog devices, but are having some issues. Our main problem is asymmetric outputs from clockwise rotation to counter clockwise rotation. When connected to a power supply on the bench top, the null voltage is 2.500 V, however when connected to the controller, the null voltage is 2.550 V (523 analog output). Another issue is when the gyro is rotated at a maximum rate, the output of the gyro is only 4.89 V (1006 analog output). I was just wondering how other teams were using the gyro or if any other teams have had similar problems and maybe a solution to these issues. Our plan is to use the gyro to monitor the angle of the robot to make a more intuitive drive system. Thanks for your help.
