Great creative idea. So searching the Steamdeck device, I discovered its underlying OS is a version of Linux but could not determine the exact CPU type (presumably arm64) nor version (Ubuntu 22.04 as I see a display of jammy )in your post) . What is the output of uname -a? Have you determined if ROS2 could be installed?
