Hi, could you please share the link to the interface docs about ROS2 interface which lists topic name, topic type and description? The screenshot is presented at timestamp 20.06
Hi tejalbarnwal7617, thanks for the reminder. I've gone through all the presentation videos and added links to the PDF or google slide docs where possible. There are still a few missing but hopefully within a day or two all videos will have link, thanks!
