Great idea - however, please keep in mind that the provisioned cloud-based system does not include Pega Robotics - and even with it, using RPA to perform OCR might be overkill. However, and maybe this a possible direction for your submission - how about integrating a third-party components such as Amazon Textract or Google Cloud Vision, potentially even resulting in a new Smart Shape or component for the marketplace?

If you want to use Pega Robotics, then the easiest way to get your hands on Robot Studio is to take this Challenge on Pega Academy (no need to enroll into the entire course, or mission, as we call them). You'll still need to bring your own machine, ideally a VM, to run Studio and Runtime though.
