You set a speed of 2pi per second, ie you instructed the robot to turn at a 
speed of 2pi per second, until you tell it to stop.

You need to understand the difference between setting the speed and setting 
the position.  In player, you can only control the speed of your robot, not 
its position.  If you need to control the position, then you need to use what 
I described to you a few days ago.

BTW, 2pi per second is fast.
