In the highly useful and detailed documentation in the readme for this repo, it is sometimes/often unclear whether you are referring to the onboard raspi or the remote computer. For example:

This ambiguity occurs in various places and can be confusing.

Only serial micro-ROS agent and serial lidar driver need to be installed on the robot computer. The other packages can be installed on either robot computer or remote computer.

For micro-ROS wifi transport and LD19 wifi forwarder, there is no robot computer. All ROS2 packages are installed on the remote computer.

Personally, I prefer remote computers/servers because they are easier to use and much faster than raspi4/5. But this really depends on applications.
