So, for example if we recorded some topics /input and /output in our ros2 bag play <bagfile> --clock For nodes to use the clock topic, specify use_sim_time: ros2 run rviz2 rviz2 --ros-args -p use_sim_time:=true API Tutorials The ROS documentation has ROS中remap一个topic 原创 最新推荐文章于 2025-09-28 13:06:16 发布 · 1w 阅读 See Also: roslaunch/XML/remap explanation and examples Names Remapping Arguments Any ROS name within a node can be remapped when it is launched at the command-line. With This page explains how to use ROS 2's bag recording and playback capabilities to save and replay message data from ROS 2 topics. The rosbag2 system allows you to record Learn how to use the ros2 bag command line tools to save topics into ROS2 bags, and later on play them again. I am not sure what is the syntax to do so in a top-level launch file to have it propagated to a nested launch file.

This document covers command To replay the data, always from the directory containing the records, you can replay the data by typing the command followed by the name of the bag file: ros2 bag play bag_file_name. The ros2 bag play command is used to replay recorded data, making it useful for testing, debugging, simulation, and algorithmic development.
