I am running a Gazebo simulation of a Husky robot equipped with a Velodyne LiDAR. I would like to record the Pointcloud message for SLAM. But whenever I start rosbag recordings, I am unable to move the robot with the Joystick. The moment I stop the recording, it moves just fine. Does anyone have a better idea to record this message in Gazebo? My computer has a big RAM, so that is not an issue.
