The node is running high frequency, low level operations on the RT-Linux kernel - thus the need for root access. I've been trying to run the node as root but the other nodes (and also tools like ros2 topic echo) don't seem to communicate with each other. Echo doesn't print anything, and callbacks on my node's are not triggered. I've tried to set up ROS_DOMAIN_ID, also sourced .bashrc and /opt/ros/foxy/setup.bash nut neither of these things seem to solve the problem. The last thing that I've tried was creating a script that executed:
Has anyone done something like that? Is there any step that I'm missing? Googling doesn't really show up anything helpfull. |

| 2021-11-22 06:40:44 -0500 | marked best answer | ROS2 - robot_description/RobotModel - cannot use URDF with meshes Hello everyone, I am struggling with preparing my URDF model for ROS2 foxy. I cannot make the RobotModel in Rviz2 to show me my robot based on the URDF. I've generated my URDF using fusion2urdf plugin for Fusion360. The urdf seems to be correct, as I've successfully loaded it into pyBullet and all links and joints behave as expected there. I've closely followed the Tutorial: https://index.ros.org/doc/ros2/Tutori... changing joint state publisher, lauchfile and setup accordingly. As far as i can tell the state publisher is working fine, so is the TF. The problem is that the robot_description topic (coming from robot_state_publisher Node I suppose) does not seem to load my STL files correctly. In the Rviz I can see the TF being displayed correctly and the RobotModel shows me that the status is OK, and that all links have been parsed successfully. Sadly all the links seem to have no geometry set. Output from running the launchfile doesn't seem to give any errors. |
