Running a published project on another PC with only the robot

Hello all,
I am still practicing UiPath and encountered a problem:
I’ve published a file on my pc that has the studio installed. Now I transfered the published project to a windows server which only has the robot installed and it doesn’t launch when running the bot from (for example) a .bat file. Is it true that the robot has to be licensed first for this to work? As currently I do not intend to purchase and use the Orchestrator, as I’m still a novice and trying to grasp all of the content. Thanks in advance!
