[ROS2 Wrapper] 4 ZED2i cameras same device in docker container

You can make a Python script that calls the reboot command for all the cameras before starting all the nodes.

Regarding the delay you can use this launch file as an example of how to use ROS2 TimerAction in a launch file:

stereolabs/zed-ros2-examples/blob/example_costmap2d/examples/zed_costmap2d_example/launch/start_example.launch.py#L177-L181


      
          # Delay Action for ZED Node and Rviz2
          delayed_nav2 = TimerAction(
              period=nav2_node_delay,
              actions=[nav2_launch]
          )

For those who have the same problem

In the end before launch several cams i reboot all of them to fix missing ones, аfter that all cams recognized by nodes
it’s worth paying attention to make reboot command work properly in docker container after installing ros and all nodes, be sure you have /usr/local/nvidia/bin at the beginning of PATH
