I am writing to ask for an advice on how I could get a heading direction (yaw) of the husky robot. I have tried subscribing to the
/husky/odom and getting the orientation values. As described in the message type, I am expecting a quaternion which I convert to Euler angles. Then I visualized the values and I am a little bit surprised, in the simulation robot rotates by less than PI/ 2.0, however, plotted odometry values indicate several 2.0 * PI rotations. I am aware of the ROS coordinates system, but there might be a bug in my conversion script. However, I am guessing the there is a misunderstanding on what type of message is being published on that particular topic. Could somebody reassure that it is the quaternion that is being published or is there a misunderstanding and a bug?
