Error Loading Custom Robotic Manipulator Model in MoveIt2 on ROS2 Humble(error launching demo.py)
Hello everyone,
I'm trying to configure my custom-made robotic manipulator to use MoveIt2 and perform motion planning and simulation in Gazebo. I'm running into some issues when trying to run the demo.launch.py file. Specifically, I'm seeing several error messages related to the controller manager and robot model not being loaded.
Here are the details: ROS Distro: ROS2 Humble Packages: gazebo_ros2_control, moveit2, and a custom package for my robot
