Yes, it is possible to run unattended Robot without Orchestartor. If the Robot is not connected to Orchestrator, you can still license it locally: Licensing a Robot.
If you have Unattended license key, it will know to “behave” as Unattended.
If we locally licensed the Robot as Unattended, it can do work as unattended Robot without connecting to Orchestrator.
That robot can run under locked screen, but you will first have to be logged in to the Robot machine, run your process manually, then lock your screen. Also there is this possibility to run the unattended robot using command line: or schedule it using windows task scheduler.
If you connect it to Orchestrator and run through Orchestrator you won’t need to have access to the Robot machine and you can run your process(Start a Job) from anywhere.
