3. On the host machine: ros2 launch clearpath_viz view_navigation.launch.py namespace:=j100_0538

Are you able to receive point clouds using the official ouster-ros driver?

It's seem to be a problem with the CPU usage going to 95% when i run all Nav2 stuffs. Now i move all the Nav2 stuffs outside the robot pc. I will let you know if it will fix

Does the problem still exist?
