The gyro can also be convenient in robot centric drive. With gyro feedback you can help to ensure that the robot is actually driving straight when you want it to or that it is rotating when you want it to. The same thing can be accomplished with encoders (or gear tooth sensors on the wheels). As a general rule closed loop control is better than open loop.
