Subject: Re: [ros-users] tf and quaternions

Hello,

I am also fighting hard to grasp the concepts of quaternions.
Could you explain how to get back the Pich, Roll and Yaw values from a
quaternion?

I understand I should come back to the axis-angle representation, but how to
extract the roll value in radians for example?

Raph
