I an new to ROS and am trying to understand the units in which the values in the Odometry.orientation.w and z fields and what do they represent. I am trying to rotate a turtlebot by a specific number of degrees. Is there a way to achieve it as I am able to set only angular velocities and whose unit I don't know either.
