What is the difference between robotic process automation (RPA) and artificial intelligence (AI)?

RPA and AI work nicely together. So, artificial intelligence (AI) is a broad term that refers to many different elements of how computers receive and process data. This is closer to how the human brain functions. RPA, on the other hand, automates tasks by following a pre-defined series of actions or phases, similar to spreadsheet macros. 

In addition, a digital worker will have human-like abilities to accomplish some activities, such as extracting data from a scanned document or invoice. Artificial intelligence is introduced to provide the required cognitive capabilities, which would need training over several cycles. Although, an AI algorithm can be incorporated into existing processes. RPA can provide the essential infrastructure, such as data sourcing and AI algorithms that offer the output reaction.
