I'm not sure that getBasis does what you think, I could be wrong though. I would try using getRotation which returns a quaternion, then grabbing the yaw from that.

tf::Quaternion q = transform_bot.getRotation(); 
double yaw = tf::getYaw(q);

Here is the getYaw documentation.

If that doesn't solve things could you edit your answer and describe what results you're observing with your current code?
