[kargarisaac]

Hi,

Any plan to support Carla v0.9.13?

Thanks

You can change the CARLA_VERSION file in the pkg of carla_ros_bridge to 0.9.13，so all is right. I can simulate in localhost machine with the above methods, but can't launch it with tcp.

您好，问一下。在本地主机上怎么打开ROS2。我也用的是Carla0.9.13，无法通过 ros2 launch carla_ros_bridge carla_ros_bridge.launch.py 这个指令打开ROS2。 期待您的答复。非常感谢！

I can't understand your question about how to launch ros2. If this, please cite on Ros2-Foxy. 我不是很清楚你所要表达的问题是否是关于如果启动Ros2，如果是这样的话，请参考Ros2官方文档Ros2-Foxy。

I wanted to test Carla0.9.13 with ROS2 and ROS bridge. The CARLA part is running correctly.Start the ROS bridge properly.(ros2 launch carla_ros_bridge carla_ros_bridge.launch.py), however when I try to launch Spawn objects, I get an error that one of the parameters is None.

My environment:

Ros 2 Foxy Carla0.9.13 on brach master Latest ROS bridge

Execution command : The CARLA part: ~$ cd carla
~$ make launch (play)

The ROS2 part: ~$ cd carla-ros-bridge ~$ source ./install/setup.bash ~$ ros2 launch carla_ros_bridge carla_ros_bridge.launch.py timeout:=30 In another terminal ~$ ros2 launch carla_spawn_objects carla_spawn_objects.launch.py

The full exception:

How can this error be resolved?

You can change the CARLA_VERSION file in the pkg of carla_ros_bridge to 0.9.13，so all is right. I can simulate in localhost machine with the above methods, but can't launch it with tcp.

Where is the CARLA VERSION file? Would you mind give a specific path to the file?

here is the file ~/carla-ros-bridge/catkin_ws/src/ros-bridge/carla_ros_bridge/src/carla_ros_bridge/CARLA_VERSION
