[ros-users] rosbag record from launch file

[Ivan Dryanovski]

Hi,

Can rosbag be invoked from a .launch file? I tried the following:

<launch>
  <node pkg="rosbag" type="record" name="record" output="screen" args="-a"/>
</launch>

It gives me the same console output as when i run "rosbag record -a".
This is the output after runnling the launch file:


... logging to /home/idryanov/.ros/log/24cb0a36-aa35-11df-82d4-00156d841fe0/roslaunch-idryanov-desktop-13809.log
