It accumulates the data passed on any number of topics and saves it in a database. Therefore, a new ROS 2 TypeSupport module library generated with the previously defined types must be created, This highly contributes to facilitating simulation of real life conditions, The recorded messages will be published by rosbag2 at their original publishing rate and the Subscriber application information, see readMessages for getting messages based on Tutorial level: Beginner. By default, the command will run in server mode (buffering data). It is intended to be high performance and avoids rosbag record subscribes to topics and writes a bag file with the contents of all messages published on those topics. The file contains interlaced, serialized ROS messages dumped directly to a single file as they come in over the wire. This is the most performance and disk-friendly recording format possible. For instance, suppose that my original teleop of turtlesim produced the following behavior: Suppose further that we want to test a control algorithm on only left turns in turtlesim. We are recording our sensor data (3 x 3D LiDAR, 3 x 2k rgb camera, IMU, GPS) in the following way and not running into any issues: Although we had some problems (frames dropping) with our network card of the computer since our cameras and lidars are ethernet based.
