Warning at step 3: Run AutoRace launch #12

Closed tranvnhan closed 6 years ago

tranvnhan commented 6 years ago

I got warning at step 3 after entering: roslaunch turtlebot3_autorace_camera turtlebot3_autorace_intrinsic_camera_calibration.launch

Here is what appeared afterward: ... logging to /home/nhan/.ros/log/848851d0-7e04-11e8-a6d2-ac7ba19ca973/roslaunch-nhan-zbook-6006.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

SUMMARY

PARAMETERS

NODES /camera/ image_proc (image_proc/image_proc) / republish (image_transport/republish)

ROS_MASTER_URI=http://localhost:11311

process[republish-1]: started with pid [6023] process[camera/image_proc-2]: started with pid [6024] [ WARN] [1530542037.119968670]: The input topic '/camera/camera_info' is not yet advertised

This seems to be the source of error since when I finish the rest of tutorial, the turtlebot is not running autonomously at all.

Hi :) tranvannhancu I am sorry for your inconvenience. This problem is the difference between the origin urdf and gazebo urdf topic names. We will solve and update it. But If you want to try it now, change to topic name in turtlebot3/turtlebot3_description/urdf/turtlebot3_burger_for_autorace.gazebo.xacro file.

Thanks, Gilbert

Hi, I have been facing the same problem. I tried with the same method in the correction for the topic name in turtlebot3/turtlebot3_description/urdf/turtlebot3_burger_for_autorace.gazebo.xacro file, but the warning still came out, and the turtlebot in the gazebo doesn't move automatically.

Is there any possible error could cause this to be happen?
