I'm trying to get position and orientation of the robot calculated by gmapping.
I used this question link text and tutorial link text as a reference.

I can get the robot position using tf::Transform::getOrigin() which is /map -> /base_link transform.
However the robot angle obtained from tf::Transform::getRotation()::getAngle() is only from 0 to π.
To determine the angle of the robot from 0 to 2π, What should I do?

Use tf::getYaw:

tf::getYaw(transform.getRotation());
