The UiPath Robot is the execution host that runs processes built in UiPath Studio. In Orchestrator, a robot entity represents an image of the UiPath Robot and controls its capabilities.
In this guide, you will learn about the robot entity as found in Orchestrator and the capabilities it provides for the UiPath Robot. To learn more about the UiPath Robot, see the Robot documentation guide.
A machine represents a physical or virtual machine on which UiPath Robot is installed. In Orchestrator, there are two machine entities that work as API key generators, which authorize the connection between the UiPath Robot and Orchestrator. Learn About Machines.
My name is John Smith. I am a call center operator in a team of 20, working on whatever laptop I find available when I get to work. In Orchestrator, my system administrator needs to define one machine template for the 20 laptops we have and a floating robot using my username. This enables me to use each of the 20 laptops using my username and the machine template's key.
I cannot use UiPath Robot on multiple machines simultaneously. If I want to use a different laptop, I must log out of the initial session.See more sample scenarios and the recommended Orchestrator setup in modern folders.
The Robot component in the UiPath suite.
The physical or virtual machine used to host and deploy UiPath Robot. In this guide, it is usually referred to as a host machine, workstation or server, to differentiate it from the machine entity in Orchestrator.
Robot (Orchestrator Entity)
Orchestrator entity that controls the connection capabilities of UiPath Robot with respect to the host machine on which it's installed. It is to be used in conjunction with the machine entity. Details below.
Machine (Orchestrator Entity)
Orchestrator entity that works as an API key generator, offering authorization capabilities for UiPath Robot. It is to be used in conjunction with the robot entity. Details here.
Supervised Robots that run under human supervision. Can be further classified according to their licensing type as follows:
- Attended - Works on the same workstation as a human user and is launched through user events.
- RPA Developer - Connects your Studio to Orchestrator for development purposes.
- Citizen Developer - Connects your StudioX to Orchestrator for development purposes.
- RPA Developer Pro - Connects your StudioPro to Orchestrator for development purposes.
Only personal workspace owners can launch processes in Orchestrator on supervised Robots by using the machine template automatically generated on their behalf.
Apart from that, you cannot start or trigger processes in Orchestrator on supervised robots, and they cannot run under a locked screen. They can only be started from UiPath Assistant or the Command Prompt.
Autonomous Robots that don't require human supervision to execute jobs. Can be further classified according to their licensing type as follows:
- Unattended - Runs without human supervision in virtual environments and can automate any number of processes. Has all the capabilities of an attended robot plus remote execution, monitoring, scheduling, and support for work queues. Can execute any process type except for test cases.
- NonProduction - Works in unattended mode for development purposes only. Cannot execute test cases.
- Testing - Works in unattended mode for development and testing purposes. Can execute test cases.
Robots are automatically licensed when you connect UiPath Assistant. All types of robots except for Citizen Developer robots can run in debug mode in Studio.
For unattended robots, licensing is performed per allocated runtime (slot) entity instead of per user. That's why Unattended, NonProduction, Testing runtimes are assigned at the machine level.
Say you have a machine template defined with 10 unattended runtimes. For each workstation connected using the key generated by that template, a pool of 10 licenses is reserved from the total number of licenses at the tenant level. A runtime is only consumed from the pool of reserved licenses during job execution. If you connect 4 machines to Orchestrator using that template, you need 40 unattended runtime licenses at the tenant level. With 25 jobs running, there are still 15 slots available for execution.
Unattended robots can be used in attended mode in a production environment (the user logs on to the machine) for logging/testing/debugging purposes.
Floating robots are robots that enable multiple users to use UiPath Robot on multiple workstations, as the robot is not tied to a specific machine. All robots in modern folders are floating robots. With one Named UserNamed User - License. Ties the usage of UiPath software to an individual user. You must obtain a separate license for each uniquely identified user accessing the product or service. license, one user can use UiPath Robot on a maximum of three machines at a time.
A user that wants to change one of the three workstations they're working on requires them to log out of a previously used machine and log into the new one.
My name is John Smith, I am a call center operator in a team of 20 working on whatever laptop I find available when I get to work. In Orchestrator, my system administrator needs to define one machine template for the 20 laptops we have, and a floating robot using my username. This enables me to use each of the 20 laptops using my username and the key generated by the machine template.
Standard robots are the predecessors of floating robots, and you can only find them when working with classic folders. A standard robot restricts the user to use UiPath Robot on a single workstation, as the robot is tied to a specific machine, namely the one set when creating the standard robot in Orchestrator. Standard robots work only for users who always work on the same machine or whose name stays the same each time the user connects to it.
Changing the workstation requires deleting the initial standard robot and recreating it using the name of the new standard machine.
My name is John Smith, I am a call center operator working daily on the same laptop whose name is LA4324. In Orchestrator, my system administrator needs to define for me a standard machine with the same exact name as my laptop, and a standard robot using my username, robot configured to connect to the standard machine named LA4324. If I ever change my laptop, the system administrator needs to delete this robot, and create a new one, for the new machine.
Robot management is performed on the Users page and involves enabling automatic robot creation for the desired user identity. The robot is automatically created according to your settings. Robot management is done automatically: you enable automatic robot creation at the user level, define its execution settings and authentication credentials, and a floating robot is automatically created.
UiPath Robot has access to the resources residing in the folders the user (and machine for unattended) has access to.
Attended robots (or unattended used in attended mode) can be monitored at the tenant level on the Robots page. Unattended machines and runtimes can be monitored at the folder level (Monitoring > Machines).
Automatic robot management can be configured for directory users or directory groups as well. The automatic robot provisioning setting for a directory group that's added to Orchestrator is inherited by any user that is a member of that AD group. Robot auto-provisioning is only valid for attended robots.

- Username/Password Credentials - This is the default method.
- SmartCard Authentication
- HSM: Luna Credential System, nShield Key Storage Provider
Robot start commands are received through SignalR or requested on a heartbeat. The username and password UiPath Robot uses for authentication purposes are transmitted only on heartbeats, enabling it to log in and execute processes.
You cannot execute processes on unattended robots unless you provided the correct user credentials.
Regardless of the Windows version a machine is running on, if you have multiple users on it, you can register a Robot on each of the users. This feature is called High-Density Robots and ensures full utilization of each machine at your disposal at its maximum potential. It can be applied to all types of Robots (Attended, Unattended, and NonProduction).
The High-Density environment has the following advantages:
- On a machine with a Windows Server (2008 R2 or 2012 R2 or 2016) operating system:
- you can run the same process with all Robots at the same time;
- you can run different processes with all Robots at the same time.
To set up High-Density Robots on a Windows Server machine, please see the Setting Up Windows Server for High-Density Robots chapter.
On the same machine, you have to connect all users as Robots to Orchestrator, all with the same Machine Name and Key.
If you register a new Robot to Orchestrator on a machine while the UiPath Robot service is running, you have to restart the service.
If the username and/or password filled in when deploying the Robot to Orchestrator do not correspond to the Windows credentials for the specified user, the first job you run is faulted, and a "Logon failure" message is displayed in the Job Details window.
