Orchestrator is a cloud platform where you can run your process remotely or schedule the process to trigger at your ease !! You can learn about all these in the above link.
UiPath Orchestrator will be useful for to schedule automated processes etc.
If you want to run in your local system only then publish automated process from studio and it will generate package and same you can run it from system tray.
@lakshman Thanks. But the main question is: Is it absolutely necessary to use UiPath Orchestrator to create and deploy a UiPath Robot on on my localhost. Looking for a clean direction.
Orchestrator won’t create anything except connection between system robot which is present in your system and orchestrator.
For running workflows you required either UiPath studio and uirobot or Uirobot only which is used for running worklfows from orchestrator.
if my answer is not correct. Can you elaborate your question?
