At least I don't think there are any teams out of Vietnam.

Maybe with some more information on the application, we could be of more help, nobtiba?

Oh, many universities in VietNam won many prizes in ROBOCON (robot contest of ASIA). I'm in Coleage of Technology (Ha Noi) team. If I can use gyro to measure angular exactly I can use it for stabilization. My duty is using ADXRS150 to do this.
ADXRS300 or the others only different in upper level (75, 150, 300 deg/s) but what about their bellow level?
I think if the sensor can't detect low rate it will lead to my following problems (in fact now):
1. Can't measure angular exactly
2. With the same real angular but measure very different values in different times
3. The same value positive and negative but measure different values (that means if you turn it clockwise then turn to starting point it never be zero)
So I wonder any body used ADXRS and measure angular exactly enough can tell me what to do?
