When I run base.launch I see the following error:

[husky_node-1] process has died [pid 17563, exit code -6, cmd /home/phandat/husky_melodic/devel/lib/husky_base/husky_node __name:=husky_node __log:=/home/phandat/.ros/log/e16926c2-4489-11ed-bda3-ff2d4b6e1391/husky_node-1.log].

  1. Which base.launch file are you running? Because I can not find any such file mentioned in their documentation.
  2. Can you please add more information? For example, which command and packages are you using?
  3. Can you please share the complete information printed in the terminal?

I launch base.launch in https://github.com/husky/husky/tree/m... I had a husky A200 robot and now I am trying to connect its hardware

I read the base.launch. I think you are probably failing to set the port argument.

https://github.com/husky/husky/blob/d...

According to the following, either the destination specified in the HUSKY_PORT environment variable or /dev/prolific is the port.

Does that mean I have to replace HUSKY_PORT or /dev/prolific with the number representing HUSKY_PORT port? And where can I find it?

It is probably a string, not a number. This is inferred from the fact that the default value is /dev/prolific. I don't have Husky and have never run husky_base.

It seems that husky_base is the node for running the actual robot. Is there a /dev/prolific in the robot's control PC?

It seems that if you want to run a simulation, you need to run another node.

I finished the simulation run and now I am running the real thing I got the above error. Exactly, it's to connect to the Husky robot's hardware Do you know how to find /dev/prolific in the robot's control PC?

Perhaps /dev/prolific is present in Husky if the wiring in Husky is correctly connected. Is /dev/prolific or some other file under /dev created on the PC in Husky when you unplug and plug the USB?
