Quaternion problem !?

Hello,

I have a problem with this function: geometry_msgs::Quaternion odom_quat= tf::createQuaternionMsgFromYaw(th);

when I give the input value "th" in degree it functions and the robot turns but with bad precision. And when I give the input in radians it doesn't function at all !!!

I don't know where's the problem !

Any suggestion please !

Regards.

This function definitely takes its input in radians. I just tested it with a few different yaw angles and the geometry_msgs::Quaternion created produced the expected values. I'm guessing the issue lies with your robot, its interfaces, or its controllers.
