Gyros measure angular velocity, not acceleration. The first integral of the velocity it the distance, so integrating a gyro provides angular distance, or relative heading.
Using a gyro to measure the robot's heading is pretty common with FIRST robots. The parts teams used last year are the Analog Devices ADXRS150EB and ADXRS300EB. The only difference is that the 150 can measure +- 150 degrees per second and the 300 measures up to 300 degrees per second.
Lots of posts describing how to do it.
