Invalid <param> tag: Cannot load command parameter
I am using ubuntu 20.04 and ros-noetic. I tried to run "roslaunch ur_moveit_config demo_gazebo.launch", but get such error.
No such file or directory: /home/jensen/ur5_ws/src/franka_ros/franka_gazebo/robots/sensor/kinect_v2.urdf.xacro [Errno 2] No such file or directory: '/home/jensen/ur5_ws/src/franka_ros/franka_gazebo/robots/sensor/kinect_v2.urdf.xacro'
