You need to set a rotation speed so that the robot turns and monitor the 
current yaw until it reaches the correct value.  Then you stop.  This is only 
a very crude solution that will make you overshoot.  A better solution would 
be to implement a P (proportional) or better a PI (Proportional Integral) 
controller.  This is a very basic thing in robotics and any(?) book on 
robotics will cover that.  Wikipedia seems not too bad either.

Hope this helps.
