I’m currently working on a project for ROS navigation using NVIDIA Isaac simulator simulation and a custom three-wheeled omnidirectional cart. I’m using this particular model from GitHub GitHub - YugAjmera/omni3ros_pkg: A ROS Package for three-wheeled omnidirectional robots.
So far, I have managed to load the URDF file of the robot into the Isaac Simulator,and I can control the robot movement through teleop_twist_keyboard. But I encountered difficulties when navigating like Carter. After running the launch file, there is no map in the Fixed Frame in rviz, and the model of the robot cannot be loaded successfully.
Here is a picture of my Action Graph:
Please let me know if you need any more information or clarification about my issue. I’m looking forward to your help and insights.
