remote_rosbag_record

ROS nodes that start/stop rosbag-record by a remote trigger

Usage

1. Launch recorder nodes with your favourite nodes. Use respawn options to record multiple times.

<launch>

  <group ns="console">
    <include file="console.machine"/>

    ... other console nodes ...
    
    <node name="console-record" pkg="remote_rosbag_record" type="record" respawn="true">
      <rosparam file="console_topics.yml"/>
      <param name="prefix" value="console"/>
      <param name="apped_date" value="true"/>
    </node>
  </group>

  <group ns="robot">
    <include file="robot.machine"/>

    ... other robot nodes ....

    <node name="robot-record" pkg="remote_rosbag_record" type="record" respawn="true">
      <rosparam file="robot_topics.yml"/>
      <param name="prefix" value="robot"/>
      <param name="apped_date" value="true"/>
    </node>
  </group>
  
</launch>

# xxx_topics.yml may look like this
topics:
- /joint_states
- /imu
- ...

1. Start rosbag-record at your own timing

• method 1: use remote_rosbag_record/trigger node

rosrun remote_rosbag_record trigger _regex:="/.*/start"

• method 2: use remote_rosbag_record/joy_listener node

rosrun remote_rosbag_record joy_listener _start_regex:="/.*/start" _start_button:=10 ...

• method 3: call trigger services from your teleoperation node

#include<remote_rosbag_record/call.hpp>

#include<boost/regex.hpp>

...

if (start_button_pressed) {
  remote_rosbag_record::call(boost::regex("/.*/start"));
}

1. Stop rosbag-record (similar to the previous step)
