Hey @Jenny, after you registered one or multiple Robots from the same machine to Orchestrator, you are required to add the machine key and Orchestrator URL in the UiPath Robot Settings window. Once the information is complete and you click Connect, Orchestrator checks its database and tries to find a match with the machine name and key added in the UiPath Robot Settings window. A Robot is uniquely identified through a machine name, a username, and a machine key while a Floating Robot is uniquely identified through an Active Directory username and a machine key.
If a match is found, Orchestrator sends back a list of all the Robots with the specified machine name and key. From here, the Robot is registered to Orchestrator and appears online in the Robots page. The Robot starts reporting its status every 30 seconds. If the connection between Orchestrator and a Robot is lost for any reason, the last known status of the Robot is displayed in the Robots page and a red exclamation mark indicates that the Robot has not sent a status update in the last 2 minutes.
