Our team purchased an ADXRS150 from Spark Fun electronics for two reasons:
(1) It is 180 degrees/sec instead of the 80 degrees/sec one that came in the kit.
(2) It works with
Kevin Watson's gyro code and with
WPILib, but the one in the KoP works with neither.
However, we've been having some problems with the accuracy of the sensor. Nevertheless, using a gyro is
definitely better than dead reckoning. If you use timers or something, a slight change in battery voltage may affect your times. If you use loop count, adding more code will increase the time per loop.
