Introduction

The Robot is UiPath’s execution agent that enables you to run processes developed in Studio. Robots need to be connected to Orchestrator in order to execute processes or they have to be licensed locally (read more about licensing). The type of Robot you have at your disposal is determined by the license, while the Robot service is determined by the deployment.

The Robot is split into several components, each being dedicated to a particular task in your automation. The Robot components are as follows:

• Service

  • Service Mode
  • User Mode
• Executor
• Command Line Interface

• UiPath Assistant

  
  

  

  
  

Having the Robot components split as explained above helps developers, support users, and computers easily run, identify, and track what each component is executing. Special behaviors can be configured per component this way, such as setting up different Firewall rules for the Executor and the Service.

The Robot can open interactive Windows sessions, under the Local System account, and has all the rights of a Windows service. Learn more about Windows sessions.

Installing the Robot using UiPathStudio.msi deploys the Service Mode Robot by default. It can also be installed from the Command Prompt, as explained on this page.

Robots can also be installed in User Mode. For your Robot, this means that it has the exact same rights as the user under which it has been installed. Installing the Robot from UiPathStudioSetup.exe deploys the User Mode Robot by default. It can also be installed from UiPathStudio.msi, as explained here, or from the Command Prompt.

Both the Service Mode and User Mode Robots can be configured as HD Robots.

Please note that packages downloaded by the Service Mode Robot cannot be run by User Mode Robots. This is because the Service Mode Robot downloads packages in the Local System (not the local user), and the User Mode Robot does not have permissions for that folder. If this happens, it is recommended to delete all packages downloaded by the Service Mode Robot, which are located in the %userprofile%\.nuget\packages folder.

Regardless of the mode in which you installed the Robot, it can still be connected to Orchestrator.
