Hi @Gokul_Jayakumar ,
A UiPath Robot is an essential and a required part of the Enterprise Platform for the execution of the Automation Project/Process. I do not think there is a possibility to achieve this without the Robot being installed somewhere on a server. Although it doesn’t have to be same system that the User/Client uses.
Maybe leveraging the use of Apps (a application could be used by the Client/User) where a user can just click on a button on the Apps and processes get executed on a Server could be helpful for your case ?
Let us know if this is not helpful.
