Number of diagonal elements in the pose covariance matrix

asked 2021-08-09 15:01:52 -0500

The control.yaml file inside the husky_gazebo package defines the value of the pose_covariance_diagonal parameter as [0.001, 0.001, 0.001, 0.001, 0.001, 0.03].

A pose is made up of 7 elements - [x, y, z,q_x, q_y, q_z, q_w]. So, shouldn't the number of elements in the pose_covariance_diagonal parameter be 7?

That covariance doesn't use a quaternion for rotation portion, it uses: roll, pitch, yaw.

Makes sense. Thanks!
