2020-09-24 20:00:07 -0500 | marked best answer | A confusion about different distribution support in ROS2 Hi, After I read through the navigation2 document in navigation2 document, I find that the features and source code between different distribution has much difference. For example, navigation2 eloquent add serveral new packages and plugins and has a change on architectural design compared to dashing. And from my test, rviz2 in ROS2 eloquent support message filters now, but ROS2 dashing still don't support this feature. My confusion here is from the ROS2 index website, the ROS2 dashing will be supported until May 2021, but ROS2 eloquent will end its life on November 2020, why the new features or functions is not added on the ROS2 LTS distribution? Though ROS2 foxy LTS is released, but because the support packages is still limited and it's running on Ubuntu20.04 which is still not supported for our robot. Hope someone could ease my confusion, Thanks. |
