Yes.

The gyro is the most-used sensor for determining the orientation of your robot with respect to the field.

It is not perfect though. Notable drawbacks are

1) it can be knocked out of calibration if your robot is hit by another robot

2) some of the KoP units have a slow drift (the angle becomes inaccurate over time)

Both of the above can be mitigated somewhat by providing the driver with a button that re-calibrates the gyro when the driver turns the robot back to the zero position.
