try the demo ? and u will see
"Making your own AI-controlled ships is a lot easier than it is in Space Engineers. If you use a shipyard to build a new ship, it will automatically be assigned a captain, which means you can issue some simple commands to it. Though, the command system could use a bit of work, unless I'm missing something"
not so easy dude you need a captain and to get a captain it's expensive... it's not that easy
