This is a question which often follows “What is Robotic Process Automation (RPA)”?
Essentially some software (called a “Software Robot” or “Bot”) simulates a person working on a computer. The “Software Robot” can simulate reading information displayed on the screen, can simulate typing on the keyboard and simulate mouse activity e.g. clicks. This enables a “Software Robot” to perform actions on computer systems just like a person. The repetitive process activity done by a person can be automated, hence “Robotic Process Automation”.
The “Software Robots” can work alongside a person, interacting with them, a bit like super “Shortcut” or a “Macro”. They act as a “Digital Assistant” to empower users to be more productive.
Alternatively, “Software Robots” can work “UnAttended” when the complete set of process tasks can be automated without people being involved. Freeing users to perform other tasks.
