Error: when trying to execute roslaunch panda_moveit_config franka_control.launch robot_ip:=<fci_ip> #395

When I try to run the roslaunch panda_moveit_config franka_control.launch robot_ip:=<fci_ip> command, I get the following error.

FrankaHW: Failed to initialize libfranka robot. libfranka: Connection error: Host not found [ERROR] [1720028829.142093723]: franka_control_node: Failed to initialize FrankaHW class. Shutting down!

It shows 'You can start planning!' after this error but automatically shuts down everything. I am using ROS Noetic with Ubuntu 20.04. I have installed franka_ros. I also installed libfranka separately because I was not sure if the error was due to libfranka.

I would appreciate it if someone could help me out with this.

Thank you!

The reason is that the real-time kernel is not properly configured //1. Add real-time group license sudo addgroup realtime sudo usermod -a -G realtime $(whoami) //2. Add restrictions to real-time groups sudo gedit /etc/security/limits.conf //3. Add the following restrictions to the opened file //Restricted content @realtime soft rtprio 99 @realtime soft priority 99 @realtime soft memlock 102400 @realtime hard rtprio 99 @realtime hard priority 99 @realtime hard memlock 102400

Then restart the real-time kernel
