create a bag file from gazebo simulation

[BurgyWu]

Hello, I am trying to use " $rostopic echo <path/to/my/robot/camera> | rostopic pub <my_robot>/camera/image sensor_msgs/CompressedImage &
$rostopic echo <path/to/my/robot/odom> | rostopic pub <my_robot>/odom nav_msgs/Odometry & $rosbag record -O <my_robot>.bag <my_robot>/camera/image <my_robot>/odom " to create a bag file. For the image msgs it works well. But with odom, it only works when just type rostopic echo <path/to/my/robot/odom> | rostopic pub <my_robot>/odom nav_msgs/Odometry,
.
When I trying to record the odom information, It has an error like
.

By the way, my Ubuntu version is 18.04 with gazebo 9

I missed this issue sorry - but it doesn't look like a RatSLAM issue. If you're still trying to do this, try using topic_tools / relay instead of the rostopic echo | rostopic pub.
