Configuring Soft Shutdown

Following these steps will allow the Build-in Computer to request the shutdown procedure on the User Computer or any computer you install.

If you are setting up your User Computer with the default IP address and username husarion select the Default configuration tab. In case the IP address or username differs from the defaults, select Custom configuration tab.

The default configuration assumes the system was installed following the steps in User Computer system reinstallation.

  1. SSH into User Computer ssh husarion@
  2. Exchange SSH public keys between the Built-in Computer and the User Computer with ssh-copy-id husarion@

By default, the ROS driver on the Built-in Computer will try shutting down the User Computer at IP address with the username husarion and the command sudo shutdown. That is why no other changes are required for it to work in the default configuration.

After following those steps, when pressing the Power Button sudo shutdown will be invoked on the User Computer. The Built-in Computer will wait for the User Computer until it gracefully shuts down before shutting down itself and powering off the robot.


The Built-in Computer's ROS driver is capable of shutting down not only one User Computer but as many as you want. It is also capable of running custom shutdown commands and much more. Refer to the panther_manager ROS package documentation to see how to edit shutdown_hosts.yaml to reflect your needs.
