humble ros1bag转ros2bag

As an AI language model, I cannot perform any actions beyond providing information. However, I can provide you with some guidance on how to convert a ROS1 bag file to a ROS2 bag file.

There are different approaches to converting ROS1 bag files to ROS2 bag files. One of the simplest ways is to use the ROS1-ROS2 bridge, which allows communication between ROS1 and ROS2 systems. To convert a ROS1 bag file to a ROS2 bag file using the bridge, you can follow these steps:

1. Install the ROS1-ROS2 bridge package on your ROS2 system. You can do this by running the following command in your terminal:

   sudo apt-get install ros-<distro>-ros1-bridge

Make sure to replace `<distro>` with the ROS2 distribution you are using (e.g., foxy, galactic).

2. Source the ROS1 and ROS2 environments in separate terminal windows:

   source /opt/ros/<distro>/setup.bash  # for ROS1
   source /opt/ros/<distro>/setup.bash  # for ROS2

3. Launch the ROS1-ROS2 bridge node in one terminal window:

   ros2 run ros1_bridge dynamic_bridge

4. In another terminal window, use the rosbag tool to play the ROS1 bag file and publish its messages to the ROS2 bridge:

   ros1bag play <ros1_bag_file> --clock --pause --loop

5. In a third terminal window, use the ROS2 bag tool to record the messages published by the bridge:

   ros2 bag record -a

This will record all the messages published by the ROS1-ROS2 bridge and save them to a ROS2 bag file.

Note that the conversion process may take some time, depending on the size of the ROS1 bag file and the complexity of the messages it contains. Also, not all message types are currently supported by the ROS1-ROS2 bridge, so you may encounter some errors or limitations during the conversion process.
