Robots questions

Greetins all,
I am new to Uipath RPA. Can some one please tell me whether uipath studio has to be installed where we run the robots? Can someone please direct me to a good resource where I can learn how the robots attended and unattended are provisioned in real world to run and to schedule. Thanks a lot,

first stop for learning is Academy:

Thank you so much for your reply. I did work out academy.uipath. However it is not very clear to me. Are there any other good resources that give real time examples? Can anyone assign Uipath work for me for free? Thanks so much for answering all my questions.
