tried that, but I think the way odom works is just one dimensional, or so what I've observed so far. I don't know if I'm wrong but I think to do sideways movement, it needs additional fixed odom frame which rviz doesn't allow. e.g rviz will only fix odom_frame but won't fix odom2_frame

robot_model release: 1.11.6.

The robot_state_publisher using robot_model release 1.11.7 still failed to launch when I built that robot_model in my workspace

It's finally working with the rebuilt robot_model, 1 version before the current one

I don't know if it's related, but running rviz returns bus error while most people complained about seg fault

Ok, I've tried rebuilding all of them. Now, the error code has changed from -7 to 127 and still died upon launch

EDIT: Nope, still error -7, and when rosrun robot_state_publisher just to check, it returns Bus error.

Sorry, quite a newbie here, what do you mean by building robot_model, i assume it's for turtlebot? What if I'm using my own robot model for rviz?

Hi, recently I upgraded my ODROID XU3 using apt-get and since then I haven't been able to launch robot state publisher which is crucial for my finals project. Whenever I want to launch my launch file, it always died with error code -7 and when I use rosrun for robot state publisher it returned 'Bus error' to the terminal.

1. Is there a quick solution to this?
2. If not, is there an alternative to robot state publisher? I intend to use my robot for gmapping, and I haven't been able to run robot state publisher in a separate machine like my laptop and connect to the ODROID that contains the gmapping, freenect, and differential drive package. It ended up with no mapping data received and the robot model has plenty of errors.
3. Is there an old ROS repository that I can download and replace the one in my ODROID?

Really need help real quick, it was stupid of me to update when I had the whole thing worked out, now I'm screwed.

weird, I'm still unable to make it work, it always die with error code -7

The gdb backtrace resulted in: Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".

Program received signal SIGBUS, Bus error. 0xb661ac74 in ?? () from /lib/arm-linux-gnueabihf/libpcre.so.3

PS. I'm using robot_state_publisher in my own robot, not turtlebot

the link you gave is the new robot state publisher, not the previous version

Yes I want to teleop a mecanum wheeled robot while also simultaneously do mapping, but I haven't been able to convert the encoder data into sideways movement that can be visualized using Rviz. What I've done so far is control sideways movement without Rviz visualizing it.

From what I understand, the package uses dwa_local_planner which is possible to plan a path using sideways movement, what I need is to map an area using sideways movement manually, commanded by keyboard or virtual joystick. Or am I missing something here?

I'm building a differential drive package for mecanum wheeled robot, I'm really stuck at how I can implement sideways movement into rviz, is it possible to add another odom frame that is always perpendicular to the first odom and is attached to the base_frame?

I can confirm it has stopped working on ODROID XU3 as well, I guess it only affects ARM processors. Is there a way to revert to the working version of robot_state_publisher? Need my robot to work real fast
