What tasks can a robot learn?
Simple. Any and all tasks performed on the computer using a mouse or keyboard that follow a set of well-defined actions capable of being documented (as if it were a recipe). The most common interactions involve actions performed on web pages, desktop applications, email, file systems, ERP’s, Office, among others.
The purpose of RPAs is not to replace humans, but to free them from boring and time-consuming tasks so that they can dedicate themselves to relevant tasks.
